[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] like Figure 1 - Figure 5 As shown, this application provides a fixture for machining a gear blank, including a machining equipment 1 and a gear blank 2 disposed on the machining equipment 1; and further comprising:

[0027] Specifically, such as Figure 1As shown, a clamping assembly 3 is provided on the top of the processing equipment 1. The clamping assembly 3 is used to fix the gear blank 2. The clamping assembly 3 includes an inner clamp 302, which is slidably connected to the top of the processing equipment 1 and abuts against the inner wall of the gear blank 2. An outer clamp 301 is movably inserted into the side wall of the inner clamp 302 and abuts against the outer wall of the gear blank 2. By providing a clamping assembly 3 on the top of the processing equipment 1, the two sets of inner clamps 302 can be moved to clamp against the inner wall of the gear blank 2 to process the outer wall of the gear blank 2. Alternatively, the outer clamp 301 can be inserted into the side wall of the inner clamp 302 and moved to clamp against the outer wall of the gear blank 2 to process the inner wall of the gear blank 2, thereby improving its applicability and functionality.

[0028] Specifically, such as Figure 3 As shown, a connector 303 is fixedly connected to the side wall of the outer clamp 301, and a connecting groove 3031 is opened on the side wall of the inner clamp 302. The connector 303 is connected to the inside of the connecting groove 3031. A fixing rod 304 passes through the side wall of the connecting groove 3031. A fixing groove 3041 is opened on the side wall of the connector 303, and the fixing rod 304 is inserted into the inside of the fixing groove 3041.

[0029] Specifically, such as Figure 4 As shown, the top of the inner clamp 302 is threaded with a lead screw 305, and the bottom of the lead screw 305 is rotatably connected with a wedge 306. The wedge 306 is slidably connected inside the inner clamp 302, and the fixing rods 304 are slidably connected to both sides of the wedge 306. By rotating the lead screw 305 upward, the wedge 306 can be moved upward, and at the same time, the two sets of fixing rods 304 will slide on both sides of the wedge 306 and retract inside the inner clamp 302, so that the outer clamp 301 can be removed.

[0030] Both the outer clamp 301 and the inner clamp 302 are provided with rubber pads 307 on their side walls. The rubber pads 307 improve the tightness and stability of the outer clamp 301 and the inner clamp 302 when clamping the gear blank 2.

[0031] Specifically, such as Figure 5 As shown, an adjustment component 4 is provided at the bottom of the clamping component 3. The adjustment component 4 is used to move the clamping component 3. The adjustment component 4 includes a bidirectional screw 402, which is provided on the inner wall of the processing equipment 1. The inner clamp 302 is slidably connected above the bidirectional screw 402. By providing the adjustment component 4 at the bottom of the clamping component 3, the inner and outer positions of the clamping component 3 can be moved and adjusted according to the position to be processed of the gear blank 2 by rotating the bidirectional screw 402 on the adjustment component 4, thereby improving its ease of use.

[0032] The bottom of the inner clamp 302 is fixedly connected to a slider 401, and the top of the processing equipment 1 is provided with a slide groove 4011, in which the slider 401 is slidably connected.

[0033] The bidirectional screw 402 is rotatably connected inside the slide groove 4011, and the slider 401 is threadedly connected to the outer peripheral wall of the bidirectional screw 402. A motor is installed inside the slide groove 4011, and the output shaft of the motor is fixedly connected to the bidirectional screw 402. The motor can drive the bidirectional screw 402 to rotate, and at the same time, the bidirectional screw 402 can drive the two sets of sliders 401 and the inner clamp 302 to slide, so as to clamp and fix the gear blank 2.

[0034] The specific solution is as follows: When processing the outer wall of the gear blank 2, first move and merge the two sets of inner clamps 302, then place the gear blank 2 on the processing equipment 1, and then drive the bidirectional screw 402 to rotate by the motor. At the same time, the bidirectional screw 402 drives the two sets of sliders 401 and the inner clamps 302 to slide to both sides until the inner clamps 302 support and clamp the inner wall of the gear blank 2, so that the outer wall of the gear blank 2 can be processed.

[0035] When machining the inner wall of the gear blank 2, firstly, the two sets of inner clamps 302 are moved and unfolded. Then, the connector 303 on the outer clamp 301 is inserted into the connecting groove 3031 of the inner clamp 302. Next, by rotating the lead screw 305 downward, the lead screw 305 can drive the wedge 306 to move downward. At the same time, the two sets of fixing rods 304 slide on both sides of the wedge 306 and are inserted into the fixing groove 3041 of the connector 303 for fixation. Finally, the gear blank 2 is placed on the machining equipment 1, and the bidirectional screw 402 drives the two sets of outer clamps 301 and inner clamps 302 to slide towards each other until the outer wall of the gear blank 2 is clamped by the outer clamp 301, so that the inner wall of the gear blank 2 can be machined.
