Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1:

referring to fig. 1 to 4, the present embodiment provides a mechanical automatic clamping device, including: the device comprises an installation frame 1, a clamping component which is arranged on the installation frame 1 and used for clamping an object, and a lifting component which is connected with the clamping component and is suitable for lifting the clamping component. The whole mounting frame 1 is a door-shaped structure, the clamping component is positioned at the opening part of the door-shaped structure, and the lifting component is positioned at the top part of the door-shaped structure.

Specifically, the clamping assembly comprises: a mounting block 61 and a pair of clamping blocks 66 provided on the mounting block 61 for clamping an object; a grip plate 610 for directly contacting an object is also integrally provided on the grip block 66. The pair of holding blocks 66 are used for holding and releasing an object through the relative opening and closing movement thereof, and when the pair of holding blocks 66 are closed, the holding of the object is realized, and when the pair of holding blocks 66 are opened, the object is released.

Therefore, the pair of holding blocks 66 of the present embodiment is further connected with a driving structure adapted to drive the opening and closing thereof, based on the switching control of the opening and closing of the pair of holding blocks 66.

Referring to the drawings for illustrating an alternative implementation, the driving structure includes a first guide rod movably connected with a pair of clamping blocks 66, a first hydraulic cylinder 64 fixed on the mounting block 61, and a pair of symmetrically distributed inclined plates 62 arranged at one end of the mounting block 61 away from the rope 57; wherein the telescopic end of the first hydraulic cylinder 64 is connected with a first guide rod 65; a guide groove 67 which is in sliding fit with the guide rod is arranged in the clamping block 66; and a pair of clamp blocks 66 provided between the facing end surfaces of the pair of inclined plates 62; and a pair of clamp blocks 66 are slidably engaged with a pair of inclined plates 62 in a one-to-one correspondence. The mounting block 61 is concavely provided with a U-shaped concave cavity for assembling the first hydraulic cylinder 64; and a pair of gripping blocks 66 also extend partially into the U-shaped recessed cavity.

Note that, a pair of swash plates 62 are each disposed obliquely with respect to the first hydraulic cylinder 64; the distance between the ends of the pair of swash plates 62 remote from the first hydraulic cylinder 64 is smaller than the distance between the ends thereof close to the first hydraulic cylinder 64; and the matching surface of the clamping block 66 and the sloping plate 62 is an inclined surface; and the distance between the ends of the inclined surfaces of the pair of inclined plates 62, which are fitted with the clamp blocks 66, away from the first hydraulic cylinder 64 is smaller than the distance between the ends thereof, which are close to the first hydraulic cylinder 64.

Furthermore, a second chute 63 is provided on the inclined surface of the inclined plate 62 that engages with the clamp block 66 in the direction of inclination of the inclined plate 62; a second sliding block 68 which is suitable for being in sliding fit with the second sliding groove 63 is convexly arranged on the inclined surface of the clamping block 66 matched with the inclined plate 62; and a first spring 69 is also provided between the wall of the second runner 63 remote from the first hydraulic cylinder 64 and the second slide 68. With such a structure, when the extending end of the first hydraulic cylinder 64 is in an extending state, the pair of clamping blocks 66 slide along the second sliding grooves 63 on the sloping plate 62 to move in a direction away from the first hydraulic cylinder 64, so that the pair of clamping blocks 66 are relatively folded to clamp an object; when the extended end of the first hydraulic cylinder 64 is in the retracted state, the pair of holding blocks 66 slides along the second sliding slot 63 on the inclined plate 62 to move in a direction approaching the first hydraulic cylinder 64, so that the pair of holding blocks 66 are relatively opened to release the object.

After the object is clamped, the object is lifted by the lifting assembly so as to receive the next operation procedure. Therefore, the present embodiment achieves the above-mentioned needs by a lifting assembly, specifically, the lifting assembly comprises: the rope winding device comprises a rope 57 connected with a mounting block 61, a wire winding roller 56 for winding the rope 57, a rotating shaft 54 fixedly connected with the wire winding roller 56, and a rotary power structure connected with the rotating shaft 54 for driving the rotating shaft 54 to rotate. That is to say for the clamped object by means of the integral lifting of the mounting block 61.

And the mounting block 61 is in sliding fit with the mounting frame 1 based on the definition of the track of the mounting block 61 during lifting so as to prevent the mounting block 61 from deviating from the track during lifting; and the mounting block 61 is fixedly connected with a pair of first sliding blocks 4; and a pair of first sliding grooves 3 which are matched with the pair of first sliding blocks 4 one by one are arranged on the mounting frame 1. With such a structure, when the mounting block 61 performs the lifting movement, the first slider 4 moves along the first sliding chute 3.

Next, by way of example, with reference to the accompanying drawings, an alternative embodiment is illustrated, in which the rotary power structure includes: a pair of fixing lugs 53 fixedly arranged at the top of the mounting frame 1 and rotationally matched with the rotating shaft 54, a second gear 55 connected with one end of the rotating shaft 54, a first gear 52 in transmission connection with the second gear 55, and a rotating motor 51 fixedly connected with the first gear 52; the top of the mounting frame 1 is provided with a through hole 2 for the rope 57 to pass through. The lifting movement of the mounting block 61 is achieved by the rotation of the rotating shaft 54 driven by the operation of the rotating motor 51 to release and wind the rope 57.

In summary, for the mechanical automatic clamping device of the embodiment, when the mechanical automatic clamping device is used, the first hydraulic cylinder 64 is started, the first hydraulic cylinder 64 drives the first guide rod 65 to descend, the first guide rod 65 is matched with the guide groove 67 to drive the clamping block 66 to descend, and then the second sliding groove 63 on the inclined plate 62 is matched with the second sliding block 68 on the clamping block 66 to drive the clamping block 66 to move towards each other, so as to drive the clamping plate 610 on the clamping block 66 to clamp the goods, the rotating motor 51 is started, the rotating motor 51 drives the first gear 52 to rotate, the first gear 52 drives the second gear 55 to rotate, the second gear 55 drives the wire take-up roller 56 on the rotating shaft 54 to rotate, so as to drive the rope 57 to take up the goods and lift the goods.

Example 2:

referring to fig. 5, based on the mechanical automatic clamping device of embodiment 1, the mechanical automatic clamping device of this embodiment further includes a braking component connected to the rotating shaft 54.

Referring to the drawings for an alternative embodiment, the brake assembly includes a disc 71 connected to the shaft 54 and having a hollow cavity 72 extending through both axial ends thereof, a pair of friction blocks 77 disposed in the hollow cavity 72 of the disc 71 and adapted to abut against the walls of the hollow cavity 72, and a brake power structure connected to the pair of friction blocks 77 and adapted to drive the pair of friction blocks 77 to move toward and away from each other. The braking power structure comprises a pair of connecting rods 76 which are connected with a pair of friction blocks 77 in a one-to-one hinged mode, a mounting rod 75 which is movably connected with the pair of connecting rods 76 at the same time, and a second hydraulic cylinder 74 which is fixedly connected with the mounting rod 75. The rotating shaft 54 penetrates through the fixing lug 53 and is connected with the disc 71.

The relative opening and closing movement of the pair of friction blocks 77 is achieved by the action of the second hydraulic cylinder 74 in cooperation with the mounting rod 75 and the pair of connecting rods 76. When the pair of friction blocks 77 are relatively opened, the disc 71 can be abutted against the cavity wall of the hollow inner cavity 72 of the disc 71, so that the disc 71 is braked by the pair of friction blocks 77 and cannot rotate together with the rotating shaft 54, and the function of restraining the rotation of the rotating shaft 54 is also realized, so that the rotating shaft 54 cannot normally rotate.

In addition, in an alternative implementation, a mounting plate 73 is further fixedly arranged on the top of the mounting frame 1; one end of each friction block 77, which is far away from the rotating shaft 54, is provided with a moving block 79, and the moving blocks 79 are movably matched with second guide rods 710; the second guide rod 710 is fixedly arranged in the mounting groove 78 arranged on the mounting plate 73; a second spring 711 is sleeved on the second guide rod 710; and both axial ends of the second spring 711 are restricted between one of the groove walls of the mounting groove 78 and the moving block 79. The mounting plate 73 here also serves as a fixing for the second hydraulic cylinder 74. The second spring 711 is provided to quickly return the pair of friction blocks 77 when the second hydraulic cylinder 74 is deactivated, i.e., the friction blocks 77 are disengaged from the wall of the hollow cavity 72 of the disc 71, so that the rotating shaft 54 can return to its rotating state.

In summary, in the mechanical automatic clamping device of the present embodiment, when the position of the lifted goods is fixed, the second hydraulic cylinder 74 is activated, the second hydraulic cylinder 74 drives the mounting rod 75 to move, and then the mounting rod 75 drives the two connecting rods 76 to push the friction block 77 to be closely attached to the inner wall of the friction groove 72 through the mounting groove 78, the moving block 79 and the second guide rod 710, so that the rotation of the rotating shaft 54 is stopped, the rope 57 is stopped to be contracted, and the lifted goods are also stopped.
