[0032] Example 1

[0033] Reference Figure 1 , Figure 2 , Figure 5 This is the first embodiment of the present utility model, which provides a fixture for machining motor shafts, which includes a machining table 100.

[0034] The fixing unit 200 includes a connecting plate 201 disposed on the processing table 100, a cylinder 204 disposed on the connecting plate 201, a connecting member 202 disposed at the output end of the cylinder 204, and a clamping member 203 disposed on the connecting member 202.

[0035] The adjustment unit 300 includes a drive member 301 disposed on the processing table 100, and a motion member 302 disposed on the drive member 301. The motion member 302 is used to control the clamping member 203 to move.

[0036] When in use, adjust one side of the cylinder 204, and the connecting member 202 drives the clamping member 203 to fix one end of the rotating shaft. Then, open the driving member 301, and the driving member 301 drives the clamping members 203 on both sides to move closer until the other end of the rotating shaft moves into the driving clamping member 203 on the other side. Then, the cylinder 204 and the connecting member 202 can drive the clamping member 203 to fix it. The clamping range and the amplitude of movement can be adjusted according to the actual situation.

[0037] Example 2

[0038] Reference Figures 1 to 6 This is the second embodiment of the present invention. Unlike the previous embodiment, the connecting member 202 includes a sleeve 202a fixedly mounted on the connecting plate 201. The sleeve 202a has a connecting groove 202b. A sliding cylinder 202c is fitted onto one end of the sleeve 202a. A sliding groove 202d is provided on the sliding cylinder 202c. A limit block 202e is provided on the sleeve 202a. The output end of the cylinder 204 passes through the connecting groove 202b and is fixedly connected to the sliding cylinder 202c.

[0039] The clamping component 203 includes a first connecting rod 203a disposed on the sleeve 202a, a second connecting rod 203b disposed on the sliding cylinder 202c, a first connector 203c disposed on the first connecting rod 203a, a second connector 203d disposed on the second connecting rod 203b, a clamping plate 203e fixedly disposed on the first connector 203c, and an anti-slip pad 203f fixedly disposed on the clamping plate 203e. The first connecting rod 203a is slidably connected to the first connector 203c, the second connecting rod 203b is slidably connected to the second connector 203d, and the anti-slip pad 203f is made of rubber.

[0040] When cylinder 204 is opened, the output end of cylinder 204 drives the sliding cylinder 202c to move laterally along the slide groove 202d under the action of the limit block 202e. Then, under the action of the first connecting rod 203a and the second connecting rod 203b, the clamping plate 203e moves accordingly. It can be adjusted according to the actual size of the rotating shaft. The rotating shaft can be fixed under the action of the anti-slip pad 203f.

[0041] The driving component 301 includes a motor 301a fixedly mounted on the processing table 100. A starting bevel gear 301b is fixedly mounted at the output end of the motor 301a. A transmission rod 301c is rotatably mounted inside the processing table 100. A connecting bevel gear 301d is fixedly mounted at one end of the transmission rod 301c, and a transmission bevel gear 301e is fixedly mounted at the other end of the transmission rod 301c. The starting bevel gear 301b meshes with the connecting bevel gear 301d, and the transmission bevel gear 301e meshes with the rotating bevel gear 302c.

[0042] When motor 301a is turned on, the output end of motor 301a drives the starting bevel gear 301b to rotate, which in turn drives the transmission rod 301c to rotate under the action of the connecting bevel gear 301d, thereby driving the transmission bevel gear 301e to rotate.

[0043] The moving component 302 includes a limiting groove 302a formed on the processing table 100, a first threaded rod 302b rotatably provided on the processing table 100, a rotating bevel gear 302c fixedly provided at one end of the first threaded rod 302b, a second threaded rod 302e fixedly provided at one end of the first threaded rod 302b, two sets of sliders 302d slidably provided on the limiting groove 302a, the sliders 302d having threaded grooves, and sliders 302d being screwed onto both the first threaded rod 302b and the second threaded rod 302e, the sliders 302d being fixedly connected to the connecting plate 201.

[0044] The transmission bevel gear 301e drives the rotating bevel gear 302c to rotate, which in turn drives the first threaded rod 302b and the second threaded rod 302e to rotate, thereby causing the sliders 302d on both sides to move closer to the center or further away from the sides in the limiting groove 302a.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it.
