[0002] As a common gasket component, flat springs 7 play an important role in various mechanical structures and devices. During the processing of flat springs 7, ensuring accurate positioning of the flat springs 7 is crucial for ensuring product quality. However, most existing processing equipment lacks effective positioning fixtures, resulting in inaccurate positioning of the flat springs 7 during processing, affecting processing efficiency and product quality. Utility Model Content

[0003] In order to overcome the problem that most of the existing processing equipment in the background technology lacks an effective positioning fixture, resulting in inaccurate positioning of the flat spring 7 during the processing, affecting the processing efficiency and product quality, the utility model provides a flat spring processing positioning fixture; two sets of coaxial arc-shaped positioning clamps are installed on the annular base, and are used in conjunction with a slider and a bidirectional screw to radially clamp the flat spring to be processed so that it is coaxial with the annular base, ensuring the accurate positioning of the flat spring during the processing, greatly reducing the processing error caused by inaccurate positioning, and improving the processing quality and precision of the product. The setting of the bidirectional screw makes the installation and positioning process of the flat spring simpler and faster, thereby improving the operating efficiency.

[0004] To achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a plane spring processing positioning fixture mainly includes an annular base, an arc-shaped positioning clamp, a support block, a bidirectional screw, and a slider. The outer diameter of the annular base is larger than the outer diameter of the plane spring, and the inner diameter of the annular base is smaller than the outer diameter of the plane spring. Two groups of guide grooves are symmetrically opened on the outer wall of the annular base, and a radially slidable slider is installed in the guide groove. The arc-shaped positioning clamp is fixed to the slider by screws and is coaxial with the annular base. It is located at the top of the annular base. Support blocks are evenly installed on the inner wall of the annular base in the circumferential direction. The top surface of the support block is higher than the top surface of the annular base. The bidirectional screw is installed on the support block through a bearing, and the end passes through the outer wall of the annular base and is threadedly connected to the slider.

[0005] The inner wall of the arc-shaped positioning clamp is provided with an arc-shaped positioning groove for clamping the outer edge of the plane spring. The cross section of the arc-shaped positioning groove is a V-shaped structure, and the height of the arc-shaped positioning groove is consistent with the height of the top surface of the support block.

[0006] Connecting blocks fixedly connected to the workbench are evenly arranged on the outer wall of the annular base along the circumferential direction.

[0007] A handle is vertically installed at one end of the bidirectional screw.

[0008] Beneficial effects of the utility model:

[0009] The utility model installs two sets of coaxial arc-shaped positioning clamps on the annular base, and is used in conjunction with a slider and a bidirectional screw to radially clamp the plane spring to be processed so that it is coaxial with the annular base, ensuring the accurate positioning of the plane spring during the processing, greatly reducing the processing error caused by inaccurate positioning, and improving the processing quality and precision of the product. The setting of the bidirectional screw makes the installation and positioning process of the plane spring simpler and faster, thereby improving the operating efficiency.

[0013] In order to make the purpose, technical solutions and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0014] The utility model discloses a plane spring processing positioning fixture, which mainly includes an annular base 1, an arc-shaped positioning clamp 2, a support block 3, a bidirectional screw 4, and a slider 5. The outer diameter of the annular base 1 is larger than the outer diameter of the plane spring, and the inner diameter of the annular base 1 is smaller than the outer diameter of the plane spring. Two groups of guide grooves 101 are symmetrically opened on the outer wall of the annular base 1, and a radially slidable slider 5 is installed in the guide groove 101. The arc-shaped positioning clamp 2 is fixed to the slider 5 by screws and is coaxial with the annular base 1 and is located at the top of the annular base 1. Support blocks 3 are evenly installed on the inner wall of the annular base 1 along the circumferential direction. The top surface of the support block 3 is higher than the top surface of the annular base 1. The bidirectional screw 4 is installed on the support block 3 through a bearing, and the end portion passes through the outer wall of the annular base 1 and is threadedly connected to the slider 5.

[0015] During use, the operator places the planar spring 7 to be processed on the support block 3, and then rotates the bidirectional screw 4, and drives the slider 5 and the arc-shaped positioning clamp 2 to move radially toward each other along the annular base 1 through the bidirectional screw 4, and radially clamps the planar spring 7 to be processed so that it is coaxial with the annular base 1, ensuring the precise positioning of the planar spring 7 during the processing process, greatly reducing the processing error caused by inaccurate positioning, and improving the processing quality and precision of the product. The setting of the bidirectional screw 4 makes the installation and positioning process of the planar spring simpler and faster, and improves the operating efficiency.

[0016] An arc-shaped positioning groove 201 for clamping the outer edge of the planar spring is provided on the inner wall of the arc-shaped positioning clamp 2. The cross-section of the arc-shaped positioning groove 201 is a V-shaped structure, and the height of the arc-shaped positioning groove 201 is consistent with the height of the top surface of the support block 3; the V-shaped structure of the arc-shaped positioning groove 201 can tightly clamp the outer edge of the planar spring to be processed, providing stable positioning and fixing, and avoiding processing errors caused by the movement of the planar spring 7 to be processed.

[0017] Connecting blocks 102 fixedly connected to the workbench are evenly arranged on the outer wall of the annular base 1 along the circumferential direction to ensure the stability of the entire fixture.

[0018] A handle 6 is vertically mounted on one end of the bidirectional screw 4 , so that an operator can control the rotation of the bidirectional screw 4 by manually rotating the handle 6 .

[0019] Working process:

[0020] During use, the operator places the plane spring 7 to be processed on the support block 3, and then controls the rotation of the bidirectional screw 4 by manually rotating the handle 6. The bidirectional screw 4 drives the slider 5 and the arc-shaped positioning clamp 2 to move toward each other along the radial direction of the annular base 1, and radially clamps the plane spring 7 to be processed so that it is coaxial with the annular base 1, ensuring the precise positioning of the plane spring 7 during the processing, greatly reducing the processing error caused by inaccurate positioning, and improving the processing quality and precision of the product. After the processing is completed, the bidirectional screw 2 is rotated in the opposite direction by the handle 6, further driving the arc-shaped positioning clamp 2 to disengage from the plane spring 7, making it convenient for the operator to remove the plane spring 7; the setting of the bidirectional screw 4 makes the installation and positioning process of the plane spring simpler and faster, and improves the operating efficiency.

[0021] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
