[0003] Currently, the machining tooling used in the processing of traction sheave seats has many shortcomings. The clamping method of the existing tooling is relatively cumbersome and the clamping efficiency is low, which not only increases the processing time cost but also reduces the production efficiency. In addition, the existing tooling has poor versatility. Different tooling is often required for different models and specifications of traction sheave seats, which makes the tooling clamping have certain limitations. Utility Model Content

[0004] In view of the problems existing in the machining tooling of the traction sheave seat, this utility model is proposed.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a machining fixture for a traction wheel seat.

[0025] This utility model provides, for example Figure 1-3 The traction sheave seat machining fixture shown includes a base 1. The top of the base 1 has an adjustment groove 2 with a cross-shaped cross section. The inner wall of the adjustment groove 2 is provided with multiple adjustment screws 3. The screws 3 are threaded with sliders 4. The sliders 4 are slidably disposed in the adjustment groove 2 and are fixedly provided with a support block 5 at their top. The upper side of the support block 5 is fixedly provided with a guide block 6. The guide block 6 is a T-shaped guide block. The guide block 6 is slidably fitted with a locking block 7. Each locking block 7 has a pushing inclined surface on the upper side of one of its opposite ends. The inside of the locking block 7 is provided with a guide hole that cooperates with the sliding of the guide block 6. An elastic telescopic rod 8 is fixed between the guide block 6 and the inner wall of the guide hole.

[0026] Before machining the traction sheave seat, the specifications of the traction sheave seat are first determined, and then the clamping range of the tooling is adjusted. First, the adjusting screw 3 is rotated. Due to the threaded engagement, the slider 4 will move along the axial direction of the adjusting screw 3 in the adjusting groove 2. At this time, the T-shaped guide block 6 engages with the guide hole of the clamping block 7, restricting the movement trajectory of the clamping block 7, so that it can only slide along the direction of the guide block 6, ensuring the stability of the movement of the clamping block 7. The pushing inclined surface design on the upper side of the clamping block 7 away from the traction sheave seat allows the pushing inclined surface to guide the traction sheave seat to smoothly push the clamping block 7 inward when the traction sheave seat is placed. At the same time, the elastic telescopic rod 8 plays a role in buffering and adaptive adjustment, ensuring that the clamping block 7 can fit tightly against the side of the traction sheave seat and achieve stable clamping.

[0027] To achieve synchronous rotation of multiple adjusting screws 3, facilitating rapid adjustment of the tooling's clamping range, such as... Figure 1-3As shown, a synchronous drive mechanism is provided between multiple adjusting screws 3. The synchronous drive mechanism is used to drive multiple adjusting screws 3 to rotate synchronously. The synchronous drive mechanism includes a drive rod 9, which is rotatably located inside the lower end of the base 1. The top of the drive rod 9 passes through the adjusting groove 2 and is fixedly provided with a drive bevel gear 10. A transmission bevel gear 11 is fixedly provided at one end of each of the multiple adjusting screws 3 that is close to each other. The drive bevel gear 10 and the transmission bevel gear 11 are configured to cooperate with each other. A rotating plate 12 is fixedly provided at the bottom of the drive rod 9.

[0028] When the clamping range of the tooling needs to be adjusted, the operator rotates the rotating plate 12. The rotating plate 12 drives the drive rod 9 to rotate as well. The drive bevel gear 10 at the top of the drive rod 9 rotates accordingly. Since the drive bevel gear 10 meshes with each transmission bevel gear 11, the rotation of the drive bevel gear 10 will drive multiple transmission bevel gears 11 to rotate synchronously, thereby realizing the synchronous rotation of multiple adjusting screws 3. This synchronous drive method allows the operator to adjust the position of multiple sliders 4 at one time.

[0029] To prevent the rotating plate 12 from rotating accidentally after adjustment, such as Figure 2-3 As shown, the side of the rotating plate 12 is provided with a plurality of spaced slots 13, and the back side of the base 1 is provided with a groove. A crossbar 14 is fixedly installed in the groove. A clamping plate 15 is rotatably fitted on the wall of the crossbar 14. The end of the clamping plate 15 is inserted into the slot 13. Both ends of the crossbar 14 are fitted with torsion springs 16. The two ends of the torsion springs 16 are fixedly connected to the crossbar 14 and the clamping plate 15, respectively.

[0030] When adjusting the rotating plate 12, the operator needs to overcome the elastic force of the torsion spring 16 and pull the retaining plate 15 out of the current retaining slot 13. At this time, the rotating plate 12 can be rotated freely. After adjusting to the appropriate position, the retaining plate 15 is released. Under the action of the torsion spring 16, the retaining plate 15 will automatically spring back and insert into the corresponding retaining slot 13 on the rotating plate 12, thereby restricting the rotation of the rotating plate 12 and preventing the adjusting screw 3 from rotating accidentally.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
