Detailed Description

The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-6, a convenient clamping anchor clamps, including the three-jaw chuck device that has chuck body 1, movable jack catch 2 and jack catch actuating mechanism, equal rigid connection is provided with the fan-shaped mounting disc 3 that is not more than 120 circumferential angle on every movable jack catch 2, the preceding terminal surface of mounting disc 3 is parallel with 1 terminal surface of chuck body, 3 outer edge positions of mounting disc 3 lean on mounting disc 3 direction side to have by platform 4, and 3 inboards of mounting disc have a plurality of ka tai 5 that are fan-shaped and arrange, the preceding terminal surface of ka tai 5 perpendicular to mounting disc 3, and the preceding terminal surface direction side that ka tai 5 kept away from mounting disc 3 is provided with to 3 outer edge direction side extension's of mounting disc 6, mounting disc 3 can be along with the activity of jack catch actuating mechanism movable jack catch 2 amalgamation to the whole circle, and the ka tai 5 of all mounting discs 3 at this moment is whole circumference and distributes.

The convenient clamping fixture is used for quickly clamping and positioning the disc-shaped part 17 to be machined when the disc-shaped part is machined. When in use, the convenient clamping fixture of the invention can be integrated and applied to a milling machine or a lathe, so that the disc-shaped part 17 can be machined by the lathe or the milling machine. The tips of the key teeth are machined by a milling or turning machine apparatus.

The application mode of the integrated lathe is that the mounting disc 3 is connected with a main shaft of the lathe, and a gear end is turned by a lathe cutter. This convenient clamping anchor clamps accessible jack catch actuating mechanism drive activity jack catch 2 moves down, makes things convenient for the dish type part to place on the mounting disc, is the ka tai card between the tooth's socket to the portion of colluding that utilizes the ka tai colludes the card and follows the position in the dish type part. The movable clamping jaws 2 are driven to move oppositely by the clamping jaw driving mechanism, when the mounting disc 3 can be assembled into a whole circle along with the movable clamping jaws 2 driven by the clamping jaw driving mechanism to move, the clamping table 5 is hooked and clamped on the inner edge of the disc-shaped part 17 to realize mounting and fixing of the disc-shaped part, and at the moment, the lathe spindle can be rotated and the tool table is matched to move to perform machining operation.

Further, to ensure the mounting efficiency and the ease of operation of the disk type part 17. The clamping platforms 5 are distributed on the mounting disc 3 at equal intervals, and when the mounting disc 3 can be movably spliced into a whole circle along with the movable clamping jaws 2 driven by the clamping jaw driving mechanism, the clamping platforms 5 are uniformly distributed in the whole circumference. And the clamping table 5 is arc-shaped close to the extension direction side of the mounting disc 3. The circle of the circular arc-shaped outline of the clamping table 5 close to the extension direction side of the mounting disc 3 is concentric with the circle of the sector of the mounting disc 3. The arc profile of the clamping table 5 is consistent with the radian of the profile of the bottom of the tooth groove of the disc-shaped part 17 and is positioned on the same circle.

Furthermore, in order to facilitate the design and manufacture of the convenient clamping fixture, an embedding groove 7 matched with the clamping table 5 is formed in the mounting disc 3, and the clamping table 5 is embedded in the embedding groove 7 and connected with the mounting disc 3 through a first screw. And a connecting block 8 is arranged between the movable clamping jaw 2 and the mounting disc 3, the connecting block 8 is connected with the movable clamping jaw 2 through a second screw 9, and the connecting block 8 is connected with the mounting disc 3 through a third screw. Meanwhile, the movable clamping jaw 2 is provided with a first limiting part 10 arranged along the direction of stroke and a first limiting groove 11 vertical to the first limiting part 10, the connecting block 8 is provided with a second limiting part 12 matched with the first limiting part 10, and a second limit groove 13 matched with the first limit part 10, the second screw 9 passes through the connecting block 8 to be in threaded connection with the movable clamping jaw 2 so as to lock the connecting block 8, the mounting plate 3 is provided with a third limiting groove 14 parallel to the first limiting part 10, two side walls of the connecting block 8 can be embedded in the third limiting groove 14, the connecting block 8 is provided with a third limiting part 15, the mounting plate 3 is provided with a fourth limiting groove 16, the third limiting portion 15 is embedded in the fourth limiting groove 16 and enables the front side and the rear side of the third limiting portion 15 in the length direction of the connecting block 8 to be matched with the front wall and the rear wall of the fourth limiting groove 16, and the third screw penetrates through the mounting disc 3 and is in threaded connection with the connecting block 8 to lock the mounting disc 3.

Like this, just can very conveniently assemble the concatenation between mounting disc 3 and the activity jack catch, guarantee the stability of assembling the location, then maintain convenience very. More importantly, the processing and manufacturing difficulty is reduced, for example, the installation disc, the movable clamping jaws and the clamping table are obtained by simple and integrated processing, manufacturing and forming, so that the processing difficulty is quite large, the manufacturing cost is higher, and no economic value is achieved. The arrangement has the effect of saving materials, particularly the movable clamping jaws and the mounting disc are simple and integrated, the positioning is inconvenient during processing, the required design precision is difficult to process, and meanwhile, the processing difficulty of the combined part formed by the mounting disc 3 and the movable clamping jaws, which is obtained by removing materials from solid materials with larger volume, is higher, the cost is high, the material consumption is large, and the processing time is long and the waste is serious.

Further, the length direction of the movable clamping jaws 2 is positioned on a bisector of the mounting disc 3. Therefore, the inertia stress of the joint in the construction process is reduced.

If the convenient clamping fixture is applied to a milling machine, the chuck body is directly arranged on a mounting table of the milling machine, and the mounting method of the disc-shaped part 17 is the same as that of the scheme.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
