[0027] The embodiment of the utility model provides a clamping and positioning device for processing electric tricycle accessories.

[0028] See also Figure 1 and Figure 2 , including a clamping platform 1, a slide groove 2 is opened on the top surface of the clamping platform 1, and a bidirectional screw 3 is rotatably connected to the inner wall of the slide groove 2, and a motor 11 is fixedly installed on the outer surface of the clamping platform 1, and the bidirectional screw 3 and the output shaft of the motor 11 are fixedly connected. The bidirectional screw 3 and the motor 11 are both prior arts, and they will not be described in detail in this application. When the motor 11 is started, it can drive the bidirectional screw 3 to rotate, and the bidirectional screw 3 rotates half to the left and half to the right. When the bidirectional screw 3 rotates, it can drive the two sliding blocks 5 to move closer to or away from each other.

[0029] The bidirectional screw 3 is rotatably connected to the clamping platform 1, and the inner bottom wall of the slide groove 2 is slidably connected with a sliding block 5. The sliding block 5 is threadedly connected to the bidirectional screw 3. When the bidirectional screw 3 rotates, it can drive the two sliding blocks 5 to slide inside the slide groove 2, thereby driving the two clamping plates 7 to move closer to or away from each other, so that the clamping plates 7 can clamp brake pads 12 of different curvatures and sizes.

[0030] An auxiliary support rod 4 is fixedly connected inside the slide groove 2, and the sliding block 5 is slidably connected to the auxiliary support rod 4. The auxiliary support rod 4 provides auxiliary support for the sliding of the sliding block 5, so that the sliding block 5 can remain stable during the sliding process and avoid shaking of the sliding block 5 during the sliding process.

[0031] See also Figure 1 , Figure 2 and Figure 3 A card slot matched with the connecting rod 6 is provided on the bottom surface of the clamping plate 7, and a card hole 10 is provided on the top wall of the card slot. The card hole 10 is matched with the card column 9. The staff can plug the clamping plate 7 onto the connecting rod 6 to fix the clamping plate 7, so that the clamping plate 7 can be replaced according to the curvature of the brake pad 12 to be clamped, so that the device can clamp the brake pads 12 with different curvatures.

[0032] Two connecting rods 6 are fixedly connected to the top surface of the sliding block 5, and a clamping column 9 is fixedly connected to the top surface of each connecting rod 6. The connecting rods 6 provide support for the clamping operation of the clamping plate 7, so that the clamping plate 7 can remain stable during the clamping process to avoid shaking that affects the processing of the brake pad 12.

[0033] A limiting hole is opened inside the clamping column 9, and the limiting column 805 is slidably connected with the limiting hole. When the limiting column 805 slides through the limiting hole inside the clamping column 9, the limiting column 805 will limit the clamping column 9, so that the clamping column 9 and the clamping hole 10 maintain a relatively stable connection state, thereby improving the stability of the device.

[0034] See also Figure 2 and Figure 3 Two clamping plates 7 are arranged above the clamping platform 1. The clamping plates 7 are adapted to the curvature of the brake pad 12 and can better clamp the brake pad 12 that needs to be processed. When it is necessary to clamp brake pads 12 with different curvatures, it is only necessary to replace the clamping plates 7 corresponding to the curvature of the brake pad 12.

[0035] See also Figure 1A brake pad 12 is arranged between the two clamping plates 7. The brake pad 12 is a prior art and will not be described in detail in this application. The brake pad 12 is the main braking device of the electric tricycle. Its type and curvature will also change according to the needs of the electric tricycle on which it is installed, so that the brake pad 12 can be better applied to the electric tricycle.

[0036] See also Figure 3 and Figure 4 A limiting mechanism 8 is provided inside each clamping plate 7. The limiting mechanism 8 includes a sliding rod 801 slidably connected to the clamping plate 7. A button is installed at one end of the sliding rod 801 located outside the clamping plate 7. The staff can control the limiting mechanism 8 on the connecting rod 6 by pressing the button.

[0037] The outer surface of the sliding rod 801 is fixedly connected to a fixed ring 802, and the surface of the fixed ring 802 is fixedly connected to two connecting blocks 803. When the button is pressed, the sliding rod 801 will slide toward the inside of the clamping plate 7. The sliding of the sliding rod 801 can drive the fixed ring 802 to slide inside the clamping plate 7, and the sliding of the fixed ring 802 can drive the connecting blocks 803 to slide.

[0038] The interior of each connecting block 803 is hinged with a hinge rod 804 through a pin shaft, and one end of each hinge rod 804 is hinged with a limit column 805 through a pin shaft. Each limit column 805 is slidably connected to the clamping plate 7. When the connecting block 803 slides toward the inside of the clamping plate 7, the two limit columns 805 are pulled closer to each other by the connecting block 803 through the transmission action of the hinge rod 804, thereby canceling the limit on the clamping column 9. At this time, the clamping plate 7 can be easily removed from the connecting rod 6 for replacement, which is convenient for the device to clamp the brake pads 12 with different curvatures.

[0039] One end of the sliding rod 801 is fixedly connected to a connecting plate 806, and the outer surface of the connecting plate 806 is fixedly connected to a reset spring 807. The end of the reset spring 807 away from the connecting plate 806 is fixedly connected to the clamping plate 7. The elastic coefficient of the reset spring 807 is sufficient. Even if vibration occurs during the processing, it will not affect the clamping state of the limit column 805 and the clamping column 9. Through the setting of the reset spring 807, when the sliding rod 801 is not subjected to external force, the sliding rod 801 can be pushed to reset, so that the limit column 805 maintains the limit hole passing through the inside of the clamping column 9, so that the clamping column 9 is fixed in the clamping hole 10. At this time, the connecting rod 6 and the clamping plate 7 maintain a stably connected.

[0040] When the utility model is in use, the staff first selects a suitable clamping plate 7 according to the brake pad 12 to be clamped, and then presses the button at one end of the sliding rod 801, and the sliding rod 801 is forced to slide toward the inside of the clamping plate 7, and the sliding of the sliding rod 801 drives the fixed collar 802 to slide, and the fixed collar 802 drives the connecting block 803 to slide, and under the transmission action of the hinge rod 804, the two limit posts 805 will slide toward each other, so that the limit post 805 cancels the limiting effect on the clamping post 9, and at this time the staff aligns the clamping hole 10 opened on the bottom surface of the clamping plate 7 with the clamping post 9 at the top end of the connecting rod 6 for insertion. Then, the pressing button is released. At this time, the sliding rod 801 will automatically reset under the drive of the reset spring 807, so that the limit column 805 remains engaged with the clamping column 9, so that the clamping plate 7 is fixedly installed on the top of the connecting rod 6, which is convenient for the device to replace the clamping plate 7, and finally the device can clamp brake pads 12 with various curvatures. Finally, the motor 11 is started, and the motor 11 drives the bidirectional screw 3 to rotate. The rotation of the bidirectional screw 3 drives the two sliding blocks 5 to slide toward each other, so that the two clamping plates 7 are close to each other, and the brake pad 12 is clamped, which is convenient for subsequent processing operations.
