The present invention improves upon the linkage assembly 65 in high speed looms, which employ existing technology for other structures.

The slide bearing 34 of the present invention is of the prior art.

The working process of the invention is as follows: in the initial state, the lever mechanism a1 and the lever mechanism B24 are hinged to each other. The sliding bearing 34 in the lever mechanism B24 is nested on the round pin 31, the sliding bearing 34 is rotatably matched with the pin hole a4 in the lever mechanism a1, and the cambered surfaces 12 of the two pressing blocks a11 in the lever mechanism a1 are abutted against the sliding bearing 34 in a radial opposite mode. In the lever mechanism B24, the abutting sleeve 35 is nested on the round pin 31 and is located in the round slot 28 of one U-shaped seat 26, the position of the abutting sleeve 35 is fixed by the baffle B36 through the bolt 22, and the catch plate 33 matched with the catch slot 32 on the round pin 31 is fixed on the outer side of one U-shaped seat 26 through the bolt 22 and fixes the relative position of the round pin 31 and the U-shaped seat 26. Two low-voltage rings in the rod mechanism B24 are symmetrically distributed in the U seat 26, the abutting force of two groups of rollers 43 at two sides of the support lug 3 is in a balanced state, the abutting block C62 in each abutting mechanism 67 abuts against the corresponding abutting rod 45, the inclined plane D63 of each abutting block C62 abuts against the inclined plane C49 in the corresponding sliding groove H48, and a screw B58 is not screwed in the threaded hole B52 in each transmission shell 46. Each pressing block B13 on the support lug 3 of the lever mechanism A1 presses against the corresponding pressing block A11, the inclined plane B14 of each pressing block B13 presses against the inclined plane A7 in the corresponding sliding groove B6, and a screw A23 is not screwed in the threaded hole A10 on the end wall of each sliding groove D9. The positioning sleeves A19 in the lever mechanisms A1 are pressed into the corresponding sliding grooves D9 by the baffle plates A21 fixed on the support lugs 3 through the bolts 22, and the positioning sleeves B56 in the lever mechanisms B24 are pressed into the corresponding sliding grooves J51 by the baffle plates C59 fixed on the transmission shell 46 through the bolts 22.

In the initial state, the two springs a18 in the lever mechanism a1 are in an equally compressed state, the spring forces generated by the two springs a18 are equal, and the pressing forces of the two pressing pieces a11 on the sliding bearing 34 are equal. All the springs B44 in each abutting ring 37 in the lever mechanism B24 are in an equally compressed state, and the abutting forces of all the rollers 43 against the side wall of the lug 3 are equal. The springs C55 in the abutting mechanisms 67 are in a compressed state, and the springs C55 in all the abutting mechanisms 67 are in an equally compressed state, so that the abutting forces of all the abutting blocks C62 on the corresponding abutting rods 45 are equal.

When the rod mechanism A1 is assembled, the threaded holes A10 on the inner end wall of each sliding groove D9 are screwed into the screws A23 for a certain length, so that the screws A23 abut against the loaded sliding blocks A16, the abutting blocks B13 do not abut against the corresponding abutting blocks A11, the abutting blocks A11 are guaranteed to have a large moving space, and the sliding bearing 34 can be conveniently and smoothly inserted into the pin holes A4 on the support lugs 3 of the connecting rod A2. When the rod mechanism B24 is assembled, the threaded holes B52 in the inner end wall of each sliding groove J51 are screwed into the screws B58 for a certain length, and the length of each screw B58 penetrating into the sliding groove J51 is equal, so that the screws B58 are abutted against the loaded sliders C53, the abutting blocks C62 do not abut against the corresponding abutting rods 45, the abutting rods 45 are ensured to drive the corresponding low-pressure rings to have larger moving spaces, and the support lugs 3 of the connecting rods A2 can be smoothly inserted into the U seats 26.

When the connecting rod A2 is inserted into the U seat 26 and the assembly of the pin hole A4, the sliding bearing 34 and the round pin 31 is finished, the middle position of the connecting rod A2 in the U seat 26 is kept unchanged, and the screw B58 on each abutting mechanism 67 is sequentially and completely disassembled. The slide block C53 in each abutting mechanism 67 further penetrates into the corresponding slide slot J51 under the action of the corresponding spring C55, and the slide block C53 drives the abutting block C62 to quickly abut against the inclined surface C49 in the corresponding slide slot H48 and the corresponding abutting rod 45 through the corresponding telescopic rod B61 and pushes the abutting rod 45 to move towards the side wall of the support lug 3. The pressing rod 45 pushes the low-pressure ring to move towards the side wall of the support lug 3 and finally all the rollers 43 on the low-pressure ring are pressed against the side wall of the support lug 3. Because the support lug 3 is positioned at the middle position in the U seat 26, the two low-pressure rings are symmetrically distributed in the U seat 26 and laterally press the support lug 3, and the support lug 3 is kept at the middle position of the U seat 26 under the self-locking action of the inclined plane D63 on the pressing block C62 in each pressing mechanism 67 and the inclined plane D63 in the corresponding sliding groove H48.

When the mutually hinged lever mechanism a1 and lever mechanism B24 operate at high speed for a certain period of time, a certain degree of radial wear occurs between the two pressing blocks a11 and the sliding bearing 34, and a certain degree of lateral wear also occurs between the two sides of the support lug 3 of the connecting rod a2 and the two low-pressure rings.

When a certain degree of radial wear occurs between the two pressing blocks a11 and the sliding bearing 34, a large gap is formed between the two pressing blocks a11 and the sliding bearing 34, so that the lug 3 and the clevis 26 tend to shake radially. At this time, the two springs a18 drive the corresponding pressing block B13 to further penetrate into the corresponding sliding groove B6 through the corresponding sliding block a16 and the telescopic rod a15, respectively, the pressing block B13 radially presses the corresponding pressing block a11 against the sliding bearing 34 under the interaction of the upper inclined plane B14 of the pressing block B13 and the inner inclined plane a7 of the corresponding sliding groove B6, and instantly completes the wear compensation between the sliding bearing 34 and the pressing block a11, so that the two pressing blocks A11 tightly abut against the sliding bearing 34 again, the self-locking function of the inclined planes B14 on the two pressing blocks B13 and the inner inclined plane A7 of the corresponding sliding groove B6 ensures that the two pressing blocks A11 continuously abut against the sliding bearing 34 without moving, thereby ensuring that the connecting rod A2 support lug 3 and the sliding bearing 34 can not generate shaking along the radial direction of the round pin 31 after the rotating abrasion is generated between the connecting rod A2 support lug and the sliding bearing 34, therefore, the normal high-speed operation of the connecting rod assembly 65 is ensured, and the vibration between the connecting rod A2 and the connecting rod B25 caused by the rotation abrasion of the connecting rod A2 support lug 3 and the sliding bearing 34 is avoided.

When lateral abrasion is generated between two sides of the support lug 3 of the connecting rod A2 and the two low-pressure rings to a certain degree, a large gap is generated between the connecting rod A2 and the connecting rod B25 along the axial direction of the round pin 31, so that a large lateral amplitude shaking tendency is generated between the connecting rod A2 and the connecting rod B25. At this time, the slide block C53 in each abutting mechanism 67 on one side of each abutting ring 37 drives the corresponding abutting block C62 to further penetrate into the corresponding sliding groove H48 through the telescopic rod B61 under the action of the corresponding spring C55, the abutting block C62 drives the corresponding side abutting ring 37 to move towards the side wall of the support lug 3 of the connecting rod a2 through the corresponding abutting rod 45 under the interaction between the inclined surface D63 on the abutting ring C62 and the inner inclined surface C49 of the corresponding sliding groove D9, and instantaneously re-abuts against the side wall of the support lug 3 of the connecting rod a2, so that the re-abutting of the side wall of the support lug 3 of the connecting rod a2 after the rotating abrasion between the abutting ring 37 and the support lug 3 of the connecting rod a2 is performed to instantaneously compensate the abrasion between the abutting ring 37 and the support lug 3, so as to ensure that two low-pressure rings continuously and tightly abut against two sides of the support lug 3, thereby preventing the connecting rod a2 and a connecting rod B25 from greatly shaking along the axial direction of the round pin 31 due to generate abrasion between the support lug 3 and two low-pressure rings, and ensuring the continuous high-speed and high-efficiency operation of the connecting rod assembly 65.

The automatic instant compensation of the abrasion between the pressing block A11 and the sliding bearing 34 and the automatic instant compensation of the abrasion between the low-pressure ring and the connecting rod A2 support lug 3 can continuously and effectively ensure the continuous high-speed and high-efficiency operation of the connecting rod assembly 65, reduce the maintenance cost and the maintenance frequency of the connecting rod assembly 65 due to the abrasion of the hinged part, reduce the maintenance cost and improve the working efficiency of the connecting rod assembly 65.

The number and the distribution of the rollers 43 on the two low-pressure rings are in one-to-one correspondence, so that the two low-pressure rings are ensured to have equivalent abutting force on the support lugs 3 through the corresponding group of rollers 43. Under the normal operation condition of the connecting rod A2 and the connecting rod B25, the connecting rod A2 and the connecting rod B25 cannot generate large shake along the axial direction of the round pin 31, when the connecting rod A2 and the connecting rod B25 generate small-amplitude shake along the axial direction of the round pin 31 due to external vibration, the springs B44 corresponding to the rollers 43 on the two low-pressure rings deform to a corresponding degree under the action of the support lugs 3, the rollers 43 on the two low-pressure rings always form abutting pressure on the two sides of the support lug 3 of the connecting rod A2 under the action of the corresponding spring B44, meanwhile, the small-amplitude generated along the axial direction of the round pin 31 between the connecting rod A2 and the connecting rod B25 is effectively buffered, the impact between the support lug 3 of the connecting rod A2 and the low-pressure rings is avoided, and the abrasion between the side wall of the support lug 3 and the two low-pressure rings is reduced to the maximum extent.

When the plain bearing 34 experiences more severe damage or wear over a long period of use, the plain bearing 34 may need to be replaced. At the moment, the two screws are respectively screwed into the corresponding threaded holes A10 for a certain length and abut against the corresponding sliding blocks A16, so that the abutting blocks B13 are ensured not to drive the abutting blocks A11 to move under the action of the corresponding springs A18 after the sliding bearing 34 is axially separated from the two abutting blocks A11 along the round pin 31, and the interference of the two abutting blocks A11 on the axial installation of the new sliding bearing 34 on the round pin 31 is avoided.

After the positions of the two sliding blocks A16 are respectively fixed by the corresponding screw rods A23, the baffle B36 is removed, and a push rod A20 with larger length is inserted into the insertion hole 30 of one side wall of the U-shaped seat 26 to axially push the damaged sliding bearing 34 away from the round pin 31, and meanwhile, the damaged sliding bearing 34 pushes the abutting sleeve 35 away from the round pin 31. After the sliding bearing 34 to be damaged is separated from the round pin 31, a new sliding bearing 34 shaft is axially installed on the round pin 31 through the round groove 28 on one branch of the U-shaped seat 26 and inserted into the pin hole A4 on the lug 3. Then, the pressing sleeve 35 is remounted in the circular groove 28 on one of the U-shaped seats 26, the baffle B36 is remounted on one of the outer sides of the U-shaped seats 26 through the bolts 22 to fix the position of the pressing sleeve 35, and then the two screws A23 are removed. After the screw a23 is removed, the two sliding blocks a16 respectively drive the corresponding pressing block B13 to press the pressing block a11 again through the telescopic rod a15 under the action of the corresponding spring a18, and the two pressing blocks a11 simultaneously press the new sliding bearing 34 to form a pressing rotation fit.

In conclusion, the beneficial effects of the invention are as follows: the rod mechanism A1 in the connecting rod assembly 65 is in hinged fit with the rod mechanism B24 through the sliding bearing 34 nested on the round pin 31, and the rod mechanism A1 can continuously and effectively compensate the rotary abrasion between the rod mechanism A and the sliding bearing 34, so that the radial shaking of the round pin 31 at the hinged part of the connecting rod assembly 65 caused by the rotary abrasion is avoided. Meanwhile, the rod mechanism B24 can continuously and effectively compensate abrasion between the rod mechanism B24 and the rod mechanism A1 in the axial direction of the round pin 31 due to rotation operation, the rod mechanism A1 and the rod mechanism B24 are guaranteed not to shake in the axial direction of the round pin 31 due to abrasion, the continuous normal operation of the connecting rod assembly 65 is guaranteed, and then the high-speed loom is guaranteed not to shake noise and vibration caused by the rod mechanism A1 and the rod mechanism B24 due to mutual abrasion, the continuous normal operation of the high-speed loom is guaranteed, and the maintenance frequency and the maintenance cost of the connecting rod assembly 65 are reduced.

When the sliding bearing 34 is broken and damaged, the sliding bearing 34 can be replaced along the axial direction of the round pin 31 under the condition that the mutual hinged relation between the connecting rod A2 and the connecting rod B25 is maintained, and the maintenance efficiency of the connecting rod assembly 65 is improved.
