Description

Technical Field

[0001] This utility model belongs to the field of friction plate manufacturing technology, and in particular relates to a brazing positioning fixture for annular friction plates. Background Technology

[0002] Friction pads are functional components composed of a steel core and a layer of friction material, widely used in mechanical transmission fields such as automotive braking systems and automatic transmissions. Their core function is to convert kinetic energy into heat energy through contact friction, thereby enabling braking or power transmission.

[0003] Depending on the application, friction plates come in various shapes. One type, annular friction plates, requires multiple friction blocks to be arranged in a ring array on a back plate and fixed by brazing. To ensure the friction effect, the relative positions between the multiple friction blocks and between the friction blocks and the back plate are critical. During production, it is impossible to guarantee the accurate position of the multiple friction blocks and the back plate, requiring repeated adjustments, which seriously affects the production efficiency of annular friction plates. Utility Model Content

[0004] In view of the defects or deficiencies in the existing technology, this utility model provides a brazing positioning fixture for annular friction plates, which can position multiple friction blocks and back plates, thereby improving the production efficiency of annular friction plates.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An embodiment of this utility model provides a brazing positioning fixture for annular friction plates, including a positioning plate with annular cross-section. A reference plate is provided on the lower surface of the positioning plate. The reference plate is frustum-shaped and its axis coincides with the axis of the positioning plate. Multiple spacer plates are fixed on the outer wall of the positioning plate, and the distance between two adjacent spacer plates is equal to the width of the friction plate.

[0006] Furthermore, the outer diameter of the positioning plate is equal to the inner diameter of the annular structure composed of multiple friction blocks, which allows the multiple friction blocks to be tightly attached to the outer wall of the positioning plate, thereby positioning the multiple friction blocks using the positioning plate.

[0007] Furthermore, the maximum outer diameter of the reference plate is greater than the inner diameter of the back plate, and the minimum outer diameter of the reference plate is less than the inner diameter of the back plate, thereby ensuring that the axis of different back plates always coincides with the axis of the positioning plate, while avoiding inaccurate positioning due to the tolerance of the back plate.

[0008] Furthermore, the inner diameter of the positioning plate is smaller than the inner diameter of the back plate, and a through hole is opened at the axis of the reference plate, the diameter of which is the same as the inner diameter of the positioning plate.

[0009] Furthermore, multiple spacers are arranged in a circular array with the positioning plate axis as the center.

[0010] Furthermore, the spacer is positioned perpendicular to the plane containing the tangent of the outer wall of the positioning plate and extends away from the positioning plate, thereby ensuring consistent spacing between the multiple friction blocks.

[0011] Furthermore, a baffle is provided on the outer side of the positioning plate, and the baffle is annular.

[0012] Furthermore, one end of the partition plate is connected to the baffle plate and the other end is connected to the positioning plate, thereby fixing the partition plate and ensuring the stability of the overall structure.

[0013] Furthermore, the bottom surface of the partition plate has a sawtooth structure, and the bottom surface of the partition plate is in contact with the upper surface of the back plate. The sawtooth structure of the bottom surface of the partition plate can be used to evenly distribute the solder on the upper surface of the back plate, ensuring the uniformity of the solder coating.

[0014] Furthermore, a handle is provided on the upper surface of the positioning plate. The handle is located directly above the reference plate, which facilitates the picking up of the positioning fixture. At the same time, the positioning fixture can be rotated by the handle to facilitate the spreading of the solder on the upper surface of the back plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a positioning plate, which is annular. Multiple friction blocks can be evenly arranged along the outer wall of the positioning plate. Multiple spacer plates are fixed to the outer wall of the positioning plate to ensure the relative positions of the friction blocks. Furthermore, a reference plate is placed on the lower surface of the positioning plate, with its axis coinciding with the axis of the positioning plate. A back plate can be fitted onto the reference plate to ensure the relative positions of the back plate and the friction blocks. This eliminates the need for repeated adjustments, ensuring that the production requirements of the annular friction plate are met each time, thereby improving the production efficiency of the annular friction plate.

[0017] The annular friction plate in this invention includes a back plate 7 and multiple friction blocks 8, such as... Figure 3As shown, the back plate 7 is an annular plate, the cross-section of the friction block 8 is fan-shaped, and multiple friction blocks 8 are evenly distributed on the upper surface of the back plate 7 in an annular array. The distance between two adjacent friction blocks 8 is set so that the multiple friction blocks 8 form an annular structure, and the axis of the annular structure formed by the multiple friction blocks 8 coincides with the axis of the back plate 7. The upper surface of the back plate 7 is coated with solder, and the bottom surface of the friction block 8 is welded and fixed to the upper surface of the back plate 7 by brazing.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] A typical embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, a brazing positioning fixture for annular friction plates includes a positioning plate 1. The transverse cross-section of the positioning plate 1 is annular, and its outer diameter is equal to the inner diameter of the annular structure composed of multiple friction blocks 8. In use, the multiple friction blocks 8 are tightly attached to the outer wall of the positioning plate 1, thereby using the positioning plate 1 to position the multiple friction blocks 8 and ensuring that the axis of the annular structure composed of multiple friction blocks 8 coincides with the axis of the positioning plate 1.

[0020] The inner diameter of the positioning plate 1 is smaller than the inner diameter of the back plate 7. A reference plate 2 is provided on the lower surface of the positioning plate 1. The reference plate 2 is frustum-shaped, and the axis of the reference plate 2 coincides with the axis of the positioning plate 1. A through hole 3 is opened at the axis of the reference plate 2. The diameter of the through hole 3 is the same as the inner diameter of the positioning plate 1. The positioning plate 1 and the reference plate 2 are integrally formed.

[0021] In use, the back plate 7 is fitted onto the outside of the reference plate 2 to position the back plate 7. Since the reference plate 2 is frustum-shaped, its outer wall is inclined. The maximum outer diameter of the reference plate 2 is greater than the inner diameter of the back plate 7, and the minimum outer diameter of the reference plate 2 is smaller than the inner diameter of the back plate 7. This ensures that the axis of different back plates 7 always coincides with the axis of the positioning plate 1, and avoids inaccurate positioning due to the tolerance of the back plate 7.

[0022] Multiple partition plates 4 are provided on the outer wall of the positioning plate 1. The multiple partition plates 4 are arranged in a circular array with the axis of the positioning plate 1 as the center. The partition plates 4 are set perpendicular to the plane where the tangent of the outer wall of the positioning plate 1 is located and extend in a direction away from the positioning plate 1. A baffle 5 is provided on the outer side of the positioning plate 1. The baffle 5 is circular. One end of the partition plate 4 is connected to the baffle 5 and the other end is connected to the positioning plate 1, thereby fixing the partition plate 4 and ensuring the stability of the overall structure.

[0023] Furthermore, the distance between two adjacent spacers 4 is equal to the width of the friction block 8. In use, two adjacent friction blocks 8 are separated by spacers 4, thereby ensuring that the spacing between multiple friction blocks 8 is consistent.

[0024] The bottom surface of the partition plate 4 has a sawtooth structure. When in use, the bottom surface of the partition plate 4 contacts the upper surface of the back plate 7. The rotating positioning fixture can use the sawtooth structure of the bottom surface of the partition plate 4 to evenly distribute the solder on the upper surface of the back plate 7, ensuring the uniformity of the solder coating and thus ensuring the welding effect.

[0025] A handle 6 is provided on the upper surface of the positioning plate 1. The handle 6 is located directly above the reference plate 2. The handle 6 makes it easy to pick up the positioning fixture. At the same time, the positioning fixture can be rotated by the handle 6 to facilitate the spreading of solder on the upper surface of the back plate 7.

[0026] By setting a positioning plate, which is an annular plate, multiple friction blocks can be evenly arranged along the outer wall of the positioning plate. At the same time, multiple spacer plates are fixed on the outer wall of the positioning plate to ensure the relative position between the multiple friction blocks. In addition, a reference plate is set on the lower surface of the positioning plate, and the axis of the reference plate coincides with the axis of the positioning plate. The back plate can be fitted on the reference plate to ensure the relative position between the back plate and the multiple friction blocks. Without repeated adjustments, the production requirements of the annular friction plate can be met every time, thereby improving the production efficiency of the annular friction plate.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
