[0027] See also Figures 1 to 3 As shown, a special fixture for thin-walled gears includes a mounting base 1, a thin-walled gear clamping control component 2 is installed on the top of the mounting base 1, and a thin-walled gear clamping angle control component 3 is connected to the top of the thin-walled gear clamping control component 2, and a thin-walled gear clamping detection component 4 is arranged on the side of the thin-walled gear clamping angle control component 3; the thin-walled gear clamping detection component 4 includes a clamping block 401, a flexible pad 402, a pressure sensor 403, a processor 404, a control shell 405, a sliding inner core 406, a power supply 407, a rotating sheet 408, and a control power supply 409. 4 can avoid the damage of thin-walled gears caused by excessive clamping force. The sliding inner core 406 forms a sliding structure with the rotating piece 408 through the control shell 405, and the rotating piece 408 forms a rotating structure with the power supply 407 and the control power supply 409; the clamping block 401 is used to clamp the thin-walled gear. At this time, the flexible pad 402 can avoid the deformation of the thin-walled gear caused by the clamping block 401 being too hard. At the same time, the pressure sensor 403 can sense the clamping pressure of the thin-walled gear, thereby controlling the working condition of the motor 201, avoiding the damage of the thin-walled gear caused by excessive clamping force, and increasing the practicality of the device.

[0028] See also Figure 1 , Figure 2 and Figure 4As shown, a special clamp for thin-walled gears, a thin-walled gear clamping angle control component 3, includes a V-rod 301, a fixed seat 302, a threaded locking rod 303, a rotating ball 304, and a connecting rod 305. The thin-walled gear clamping angle control component 3 can adjust the clamp to clamp thin-walled gears of different sizes. The thin-walled gear clamping detection component 4 forms a rotating structure with the fixed seat 302 through the connecting rod 305, the rotating ball 304, and the rotating ball 304 forms a threaded detachable structure with the fixed seat 302 through the threaded locking rod 303; the clamping block 401 and the connecting rod 305 can be rotated through the rotating ball 304, so that the angle of the clamping block 401 can be adjusted, so that it can be adjusted to a suitable angle according to the size of the thin-walled gear, and thin-walled gears of different sizes can be firmly clamped. When the threaded locking rod 303 is tightened, the angle of the clamping block 401 can be fixed to avoid the clamping block 401 from loosening during the clamping of the thin-walled gear. The operation is simple and easy to use.

[0029] See also Figure 1 and Figure 5 As shown, a special clamp for thin-walled gears, a thin-walled gear clamping control component 2, includes a motor 201, a first gear 202, a lifting rod 203, a clamping control rod 204, and a second gear 205. The operation of the motor 201 can achieve the purpose of loosening the clamping of the thin-walled gear. The clamping control rod 204 forms a lifting structure through the lifting rod 203, the first gear 202 and the second gear 205, and the lifting rod 203 and the first gear 202 are meshed with each other. The thin-walled gear clamping angle control component 3 forms a rotating structure with the mounting base 1 through the second gear 205, and two second gears 205 are symmetrically arranged about the vertical center axis of the mounting base 1; through the operation of the motor 201 and through the transmission of the first gear 202 and the lifting rod 203, the clamping control rod 204 can be lifted and lowered, so that the two groups of second gears 205 can be controlled to rotate in opposite directions, so that the two clamping blocks 401 are displaced to clamp the thin-walled size.

[0030] Working principle: First, according to the size of the thin-walled gear to be clamped, the clamping block 401 is rotated to change the angle of the clamping block 401 to adapt to thin-walled gears of different sizes, so that the angle of the clamping block 401 can clamp the thin-walled gear. At this time, tighten the threaded locking rod 303 so that one end of the threaded locking rod 303 is against the rotating ball 304, and the angle of the clamping block 401 can be fixed. Then, the thin-walled gear to be clamped is placed between the two sets of clamping blocks 401 and the flexible pad 402. At this time, open The switch of the motor 201 drives the first gear 202 to rotate, so as to control the lifting rod 203 and the clamping control rod 204 to rise and fall. When the clamping control rod 204 rises, the protrusions on its side drive the two sets of second gears 205 to rotate and control the two clamping blocks 401 to separate. When the clamping control rod 204 falls, the protrusions on its side drive the two sets of second gears 205 to rotate and control the two clamping blocks 401 to close, so that the two clamping blocks 401 can clamp the thin-walled gear.

[0031] Next, when the thin-walled gear is clamped by the clamping block 401, the flexible pad 402 can prevent the clamping block 401 from being too hard and deforming the thin-walled gear clamp, and at this time the pressure sensor 403 can sense the clamping force. The pressure sensor 403 is a device or apparatus that can sense pressure signals and convert pressure signals into usable output electrical signals according to a certain rule. When the clamping pressure reaches a certain level and may cause damage to the thin-walled gear, the pressure value is sensed and processed by the processor 404 and transmitted in the form of an electrical signal, so that the sliding inner core 406 extends from the control shell 405 and pushes the rotating piece 408 to rotate around the power supply 407, thereby separating it from the control power supply 409. There is an electrical connection between the control power supply 409 and the motor 201, and the power supply 407 can provide electrical energy. When the rotating piece 408 is separated from the control power supply 409, the circuit of the motor 201 is disconnected, and the motor 201 stops working at this time, so that the thin-walled gear can be clamped and tightened while avoiding damage to the thin-walled gear.

[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.
