Description

Technical Field

[0001] The utility model relates to the technical field of threaded bushings, in particular to a clamping device for processing threaded bushings. Background Art

[0002] A threaded bushing is a part that fits over a thread. Its interior is finely machined into a threaded shape that can cooperate with the external thread to make the assembly tighter and more stable. It is often used for connecting and fixing mechanical shafts to improve the working efficiency and operating stability of mechanical equipment. At the same time, threaded bushings can also be used to repair damaged threaded holes. It is a new type of internal thread fastener product that repairs and strengthens internal threads.

[0003] The clamping devices currently used in threaded bushing processing generally have the problem of inconvenient adjustment, especially when adapting to threaded bushings of different sizes. In addition, the clamping device often lacks special treatment of the clamping block when contacting and clamping the threaded bushing, which directly leads to the tooth part of the threaded bushing being easily damaged.

[0030] Example 2:

[0031] On the basis of the first embodiment, a preferred embodiment of a clamping device for threaded bushing processing provided by the present invention is as follows: Figure 1-4 As shown, the braking part 3 includes: a fixed frame 311, fixedly connected to the top of the workbench 1; a rotating column 312, rotatably connected to the top of the workbench 1; and a motor 320, fixedly connected to the top of the limit frame 212.

[0032] The top of the rotating column 312 is fixedly connected to a gear 1 313, the outer wall of the rotating column 312 is fixedly connected to an eccentric disk 1 314, the top of the eccentric disk 1 314 is provided with an annular groove 1, the top of the fixed frame 311 is fixedly connected to a gear 2 315, the output end of the motor 320 passes through the top of the limit frame 212 and extends downward, the output end of the motor 320 is fixedly connected to the top of the gear 2 315, and the gear 2 315 is meshed with the gear 1 313.
