[0022] This assembly fixture, suitable for machining the end face of a meat grinder casing, includes a main casing 3, a bottom cover 1, a small bevel gear 7, a large bevel gear disc 6, a chuck 4, and an inner chuck 5 (see the instruction manual appendix). Figure 1 , 2 and 3).

[0023] The main housing 3 is fixed to one end of the bottom cover 1 by a screw 2; during assembly, the assembly fixture can be mounted on a lathe through the bottom cover 1.

[0024] One end of the main housing 3 is equipped with multiple claws 4 that slide along evenly spaced slide rails (see instruction manual appendix). Figure 1 and 2 The two sides of the claw 4 are provided with sliding grooves 14 (see the instruction manual). Figure 8 The claw 4 is slidably connected to the main housing 3 via the slide groove 14. When the claw 4 is under force, it can slide along the slide rail.

[0025] The main housing 3 contains a movable large bevel gear disk 6 (see the instruction manual appendix). Figure 5 , 7 (8 and 9). The large bevel gear disk 6 is meshed with the chuck 4; multiple small bevel gears 7 are movably installed on the circumferential surface of the main housing 3 on one side of the large bevel gear disk 6; the small bevel gears 7 are meshed with the large bevel gear disk 6.

[0026] The large bevel gear disk 6 has a bevel gear ring 11 at its front end; a spiral groove 12 is provided on the back of the large bevel gear disk 6; the large bevel gear disk 6 is meshed with the small bevel gear 7 through the bevel gear ring 11. A wrench position 10 is provided at the end of the small bevel gear 7. During operation, the large bevel gear disk 6 can be driven to rotate forward or backward by rotating the small bevel gear 7 through the wrench position 10.

[0027] The bottom of the chuck 4 is provided with a spiral chuck tooth 13 (see the instruction manual). Figure 7 and 8 The large bevel gear disk 6 is connected to the pawl 4 via the helical groove 12 and the helical teeth 13. With this configuration, the large bevel gear disk 6 can drive the pawl 4 to slide along the slide groove 14 via the helical groove 12 during rotation. During operation, the large bevel gear disk 6 can be driven to rotate in either direction by rotating the small bevel gear 7. During the forward or reverse rotation of the large bevel gear disk 6, the pawl 4 can be pushed together or separated.

[0028] One end of the claw 4 is fixedly fitted with an inner locking rod 5 (see instruction manual appendix). Figure 1 and 2The inner clamping rod 5 is an integral structure, comprising a positioning plate 8 and a long rod 9; one end of the clamping claw 4 is fitted with the long rod 9 via the positioning plate 8; the outer surface of the long rod 9 has an arc-shaped structure; when the various inner clamping rods 5 on the assembly fixture are brought together, the long rods 9 form a conical structure. The purpose of this design of the inner clamping rod 5 is to allow the surface of the inner clamping rod 5 to fit against the inner surface of the meat grinder housing, thereby enabling the inner clamping rod 5 to clamp and fix the meat grinder housing by supporting it outward through the long rod 9 during operation.

[0029] When this assembly fixture is in operation, it is first mounted on the lathe via the bottom cover 1; then, the large bevel gear 6 is driven to rotate in the opposite direction by the reverse rotation of the small bevel gear 7; during the reverse rotation of the large bevel gear 6, the jaws 4 and the inner clamping rod 5 are pushed together. When the inner clamping rod 5 is fully closed to form a conical integral structure (see the instruction manual appendix), Figure 1 and 2 Stop rotating the small bevel gear 7.

[0030] After the above steps are completed, insert the workpiece to be processed, the meat grinder housing, into the bottom end of the long rod 9 of the inner clamping rod 5. At this time, the inner clamping rod 5 positions the meat grinder housing through the positioning plate 8. Then, rotate the small bevel gear 7 forward to drive the large bevel gear disk 6 to rotate forward. During the forward rotation of the large bevel gear disk 6, the jaws 4 and the inner clamping rod 5 will separate from each other. When the long rod 9 of the inner clamping rod 5 contacts and locks against the inner hole of the meat grinder housing, stop rotating the small bevel gear 7.

[0031] At this point, the assembly fixture has completed the clamping of the meat grinder housing. After the lathe is started to complete the end face machining of the meat grinder housing, the assembly fixture can enter the next work cycle.

[0032] This assembly fixture, suitable for machining the end face of a meat grinder housing, has a compact structure and ingenious design. During operation, the workpiece meat grinder housing can be quickly mounted on a lathe using this assembly fixture, thereby solving the problems of inconvenient clamping and low machining efficiency in existing machining methods for meat grinder housings. It is particularly suitable for the needs of machining the end face of meat grinder housings.
