Description

Technical Field

[0001] This application belongs to the field of clamping and drilling technology, and particularly relates to a brake disc drilling device based on an adjustable clamp. Background Technology

[0002] During the manufacturing process, brake discs require drilling holes. The protruding structure at the center of the brake disc is the mounting end, which connects to the axle on the vehicle. The outer side of the mounting end is the friction end, which works in conjunction with the brake pads or brake calipers. The friction end of the brake disc has a relatively large number of holes, typically no less than 30, while the mounting end has 5 or more holes. Throughout the drilling process, a clamp is used to hold the brake disc in place; therefore, the stability of the clamp holding the brake disc is crucial.

[0003] The current fixture has the following problems:

[0004] 1. The metal parts of the clamp are in direct contact with the surface of the brake disc, especially the outer surface, which may cause some minor scratches, affecting the smoothness and appearance of the brake disc surface;

[0005] 2. The gap between the brake disc and the bottom of the clamp is too small, which makes it difficult to remove the brake disc from the clamp;

[0006] 3. The drilling positions for the brake disc are the friction end and the mounting end, but the existing fixtures all fix or clamp the edge of the friction end of the brake disc, and the mounting end lacks effective support. Utility Model Content

[0007] In order to solve the above problems, this application provides a brake disc drilling device based on an adjustable clamp.

[0008] The purpose of this application is to provide a brake disc drilling device based on an adjustable clamp. This application uses a central column to center the brake disc, a movable plate to provide downward pressure on the edge of the brake disc, a spring seat to provide upward support force on the edge of the brake disc, and a support column to support the brake disc hub, thereby achieving stable clamping of the brake disc on the clamp.

[0009] To achieve the purpose of this application, the technical solution of this application is as follows:

[0010] A brake disc drilling device based on an adjustable clamp includes a clamp and a drilling machine. The drill bit of the drilling machine is arranged above the clamp. The clamp includes a base plate, on which a vertically arranged central column is provided. Multiple support columns and multiple spring seats are arranged around the central column. The distance from the spring seats to the central column is greater than the distance from the support columns to the central column. A clamping assembly is provided on the base plate. The clamping assembly includes a hinge seat, on which a movable plate is hinged. A through groove is formed at the end of the movable plate away from the central column, and the through groove penetrates the movable plate vertically. The threaded post is inserted into the through groove, and a stop is set at the top of the threaded post. A nut is screwed onto the threaded post. The stop is arranged above the movable plate, and the nut is arranged below the movable plate. The base plate is fixed to the base of the drilling machine by bolts. The movable plate provides downward pressure on the edge of the brake disc, and the spring seat provides upward support force on the edge of the brake disc. At the same time, the support post supports the brake drum of the brake disc, realizing the stable clamping of the brake disc on the fixture. The existing mature drilling machine is used to drill the brake disc after it is stably clamped.

[0011] Furthermore, the top edge of the center column is chamfered, and the center column centers the brake disc, making it easier for the center hole of the brake disc to enter the center column, and also allowing for a greater gap between the drill bit and the center column.

[0012] Furthermore, a pressure block is provided at the lower end of the movable plate. The pressure block is arranged at the end of the movable plate near the central column. This application avoids the metal movable plate from directly contacting the surface of the brake disc by using the pressure block, thereby reducing surface scratches on the brake disc. The processed brake disc has a smooth surface and is more aesthetically pleasing overall.

[0013] Furthermore, the nut is provided with a protrusion that protrudes from the surface of the nut, and the user of this application can rotate the nut by moving the protrusion.

[0014] Furthermore, a spring is provided on the spring seat, and the spring is arranged vertically.

[0015] Furthermore, the spring seat includes a fixed seat, with a column at the center of the fixed seat. The spring is arranged on the outside of the column, and the lower end of the spring is connected to the fixed seat. After the movable plate is released, the brake disc can create a larger gap with the base plate under the action of the spring, making it easier to remove the brake disc from the clamp.

[0016] Furthermore, the base plate is provided with threaded holes, and the lower end of the threaded post is screwed into the threaded holes of the base plate.

[0017] Furthermore, lifting rings are provided on the base plate to facilitate the movement of the clamp using lifting devices.

[0018] Compared with the prior art, the beneficial effects of this application are as follows:

[0019] 1. This application uses a center column to center the brake disc, a movable plate to provide downward pressure on the edge of the brake disc, a spring seat to provide upward support on the edge of the brake disc, and a support column to support the brake disc hub, thereby achieving stable clamping of the brake disc on the fixture. The drill bit is arranged above the brake disc, and the existing mature drilling machine is used to drill the brake disc after it is stably clamped.

[0020] 2. This application arranges a pressure block at the lower end of the movable plate to prevent the metal movable plate from directly contacting the surface of the brake disc.

[0021] 3. The edge of the brake disc in this application is restricted by a spring and a pressure block. After the nut is loosened, the spring gradually returns and creates a larger gap between the brake disc and the base plate, making it easier to remove the brake disc from the clamp.

[0030] Example 1

[0031] This embodiment is a brake disc drilling device based on an adjustable clamp. The adjustable clamp is used to fix the brake disc 14 and to perform drilling operations on the fixed brake disc 14.

[0032] This embodiment includes a fixture and a drilling machine. The drilling machine is a vertical drilling device used in the prior art. The drill bit of the drilling machine is arranged above the fixture. The fixture includes a base plate 1, which is bolted to the base of the drilling machine. A vertically arranged central column 2 is installed on the base plate 1. The central column 2 is cylindrical. More specifically, in this embodiment, a chamfer is provided at the top edge of the central column 2, making the upper part of the central column 2 smaller. The central column 2 is used to center the brake disc 14. Because the upper part of the central column 2 is smaller, the center hole of the brake disc 14 is more easily inserted into the central column 2 during installation. Due to the presence of the chamfer, more space is left between the drill bit and the central column 2, which facilitates the drill bit to drill the position of the brake disc 14 near the edge of the central column 2 and avoids interference between the drill bit and the central column 2.

[0033] In this embodiment, multiple support columns 3 and multiple spring seats 4 are arranged around the central column 2. For example, in this embodiment, there are 4 support columns 3 and 3 spring seats 4. The distance from the spring seat 4 to the central column 2 is greater than the distance from the support column 3 to the central column 2, so that the support column 3 is closer to the central column 2. As a specific structure of the spring seat 4, a spring is installed on the spring seat 4. The spring is arranged vertically. More specifically, the spring seat 4 includes a fixed seat with a column at the center. The spring is arranged on the outside of the column. The lower end of the spring is connected to the fixed seat. The fixed seat is fixed to the base plate 1 by bolts or screws. After the movable plate 6 is released, under the action of the spring, the brake disc 14 can create a larger gap with the base plate 1, which makes it easier to remove the brake disc 14 from the clamp.

[0034] In this embodiment, a clamping assembly is also installed on the base plate 1. The clamping assembly includes a hinge seat 5, on which a movable plate 6 is hinged. A through groove 7 is provided at the end of the movable plate 6 away from the central column 2. The through groove 7 passes through the movable plate 6 in the vertical direction. A threaded column 8 on the base plate 1 passes through the through groove 7. The top of the threaded column 8 has a stop block 9. The size of the stop block 9 is larger than the size of the through groove 7. A nut 10 is screwed onto the threaded column 8. The stop block 9 is arranged above the movable plate 6, and the nut 10 is arranged below the movable plate 6. The stop block 9 and the nut 10 clamp and fix the movable plate 6. After the brake disc 14 is installed, the movable plate 6 provides downward pressure on the edge of the brake disc 14, and the spring seat 4 provides upward support force on the edge of the brake disc 14. At the same time, the support column 3 supports the brake hub of the brake disc 14, realizing the stable clamping of the brake disc 14 on the fixture. The brake disc 14 after stable clamping is drilled using an existing mature drilling machine.

[0035] As a fixing method for the threaded post 8, the base plate 1 of this embodiment has a threaded hole, and the lower end of the threaded post 8 is screwed into the threaded hole of the base plate 1.

[0036] To ensure the quality of the brake disc 14 at the factory, in this embodiment, a pressure block 12 is installed at the lower end of the movable plate 6. The pressure block 12 is arranged at the end of the movable plate 6 near the center column 2. The pressure block 12 avoids the metal movable plate 6 from directly contacting the surface of the brake disc 14, reducing surface scratches on the brake disc 14. The processed brake disc 14 has a smooth surface and is more aesthetically pleasing. In this embodiment, the pressure block 12 is made of rubber.

[0037] In this embodiment, the nut 10 needs to be rotated so that the movable plate 6 can be released or pressed against the brake disc 14. Therefore, in order to facilitate the rotation of the nut 10, a protrusion 11 is welded on the nut 10. For example, the protrusion 11 in this embodiment is columnar and protrudes from the surface of the nut 10. The user of this embodiment can rotate the nut 10 more conveniently by moving the protrusion 11.

[0038] To facilitate the movement of the base plate 1, a lifting ring 13 is installed on the base plate 1 in this embodiment. The lifting ring 13 is fixed to the base plate 1 by screwing or welding. Since this clamp has many metal parts and is heavy, this embodiment can use a lifting device to hook the lifting ring 13 and then move the clamp.

[0039] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0040] While the specific embodiments of this application have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of this application. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of this application are still within the scope of protection of this application.
