The holding block 306 forms an elastic structure with the support frame 301 through the second spring 307, and the support frame 301 forms a detachable structure with the clamping control component 2 through the insertion rod 304, and the insertion rod 304 forms an elastic structure with the fixing seat 302 through the first spring 303; due to the elasticity of the first spring 303, the insertion rod 304 is separated from the support block 206, the support frame 301 can be disassembled, and the clamping block 306 meshing with the thin-walled gear body 5 can be replaced and then installed. The appropriate clamping block 306 can be replaced and adjusted according to the tooth groove depth of different thin-walled gear bodies 5. The operation is simple and easy to use.

[0028] See also Figure 1 , Figure 3 and Figure 4 As shown, a clamping device for processing thin-walled gears, a clamping control component 2, includes a servo motor 201, a buffer spring 202, a shock-absorbing support sponge 203, a control gear 204, a first moving seat 205, a support block 206, and a second moving seat 207. The clamping operation can be performed according to the diameter of different thin-walled gear bodies 5. The first moving seat 205 and the second moving seat 207 are both formed into a sliding structure with the control gear 204, the servo motor 201 and the clamping device base 1, and the first moving seat 205 and the second moving seat 207 are both connected to the control gear 204. The control gears 204 are meshed with each other, and the buffer spring 202 and the shock-absorbing support sponge 203 are distributed in a ring array about the bottom of the servo motor 201, and the material of the shock-absorbing support sponge 203 is set to PU sponge; when the control gear 204 rotates clockwise, the second movable seat 207 will slide to the right, and the first movable seat 205 will slide to the left, so that the support block 206 can clamp the thin-walled gear body 5 by sliding, and can be adjusted according to the diameter of different thin-walled gear bodies 5, making the device more practical.

[0029] See also Figure 1 and Figure 5As shown, a clamping device for processing thin-walled gears, an induction alarm component 4, includes a pressure sensor 401, a telescopic shell 402, a telescopic inner core 403, a main power supply 404, a rotating piece 405, a control power supply 406, and a buzzer 407. The induction alarm component 4 is provided to assist clamping to prevent the thin-walled gear body 5 from being deformed. The telescopic inner core 403 forms a sliding structure with the rotating piece 405 through the telescopic shell 402, and the rotating piece 405 forms a rotating structure with the control power supply 406 through the main power supply 404; by providing a pressure sensor 401, when the clamping block 306 clamps the thin-walled gear body 5, the clamping block 306 will slide to one side through the slide groove 305, and the second spring 307 will provide a certain resistance. When the clamping block 306 touches the pressure sensor 401, the buzzer 407 can be controlled to work, so as to assist clamping and prevent the thin-walled gear body 5 from being deformed during clamping.

[0030] Working principle: First, select a suitable gear clamping assembly 3 according to the thin-walled gear body 5, squeeze the first spring 303 through the insertion rod 304, and then bring the fixing seat 302 close to the hole on the side of the support block 206. At this time, release the insertion rod 304, and the insertion rod 304 will be inserted into the hole on the side of the support block 206 under the elastic force of the first spring 303, so as to fix the support frame 301. Then, place the thin-walled gear body 5 on the surface of the clamping device base 1, and turn on the switch of the servo motor 201. At this time, the servo motor 201 The control gear 204 will be driven to rotate. Since the control gear 204 is meshed with the first movable seat 205 and the second movable seat 207, when the control gear 204 rotates clockwise, the second movable seat 207 will slide to the right, and the first movable seat 205 will slide to the left, so that the gear clamping assembly 3 on the top of the support block 206 can clamp the thin-walled gear body 5 by sliding. During the clamping process, the clamping block 306 will slide to one side through the slide groove 305, and the second spring 307 will provide a certain resistance.

[0031] Next, since a pressure sensor 401 is provided, the pressure sensor 401 converts the pressure into a small electrical signal, which is then transmitted and displayed. When the clamping block 306 touches the pressure sensor 401, electricity is transmitted in the form of a signal, and the telescopic inner core 403 extends from the telescopic outer shell 402, thereby pressing against the rotating piece 405 to rotate around the main power supply 404, thereby touching the control power supply 406. At this time, the circuit is connected, and the buzzer 407 will sound an alarm to remind the staff not to continue clamping to avoid deformation of the thin-walled gear body 5. Finally, since a buffer spring 202 and a shock-absorbing support sponge 203 are provided at the bottom of the servo motor 201, excessive vibration of the servo motor 201 during operation can be prevented to prevent deformation of the thin-walled gear body 5.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
