Description

Technical Field

[0001] The present application relates to the technical field of brake disc processing, and in particular to a drilling mechanism for a brake disc. Background Art

[0002] Brake disc drilling is a common processing method used to improve the heat dissipation performance and reduce the weight of the brake disc.

[0003] First, the brake disc needs to be fixed on the drilling equipment, and then the position and size of the drilling hole are determined according to the design requirements. Next, use a suitable drill bit and appropriate speed to drill, ensuring that the diameter and depth of the drilling hole meet the requirements.

[0004] Brake discs are mostly circular discs that need to be drilled with multiple holes around the center of the circle, so as to be further processed into flange holes for the installation of the brake disc. Due to the large number of flange holes, the drilling mechanisms currently used mostly drill holes one by one through an intermittent rotating seat and a drill rod, and the drilling efficiency is low. In this regard, a drilling mechanism for a brake disc is proposed to solve the above-mentioned problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides a drilling mechanism for a brake disc, which has the advantages of being easy to perform multi-hole processing at the same time, having a simple structure and low cost.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a drilling mechanism for a brake disc, comprising a machine base, on which a clamping seat for loading and fixing the brake disc is installed, a fixing frame is fixedly installed on the surface of the machine base, and a drill bit for drilling is arranged on the fixing frame;

[0007] The fixing frame is fixedly mounted with a mounting plate, and four rotating sleeves are fixedly mounted on the mounting plate. A connecting shaft is fixedly mounted on one end of the drill bit, and the connecting shaft passes through the rotating sleeve and is slidably connected to the rotating sleeve.

[0008] A servo motor for driving is fixedly mounted on the fixing frame, and a connecting mechanism is arranged between the servo motor and the connecting shaft.

[0009] Furthermore, the connection mechanism includes a connection piece fixedly mounted on one end of the connection shaft passing through the rotating sleeve, a cross is rotatably connected between four of the connection pieces, and the cross and the output end of the servo motor are connected via a cam piece.

[0010] Furthermore, the cam member includes a cam plate fixedly mounted on the output end of the servo motor, and a connecting pin is rotatably mounted on one end of the cam plate away from the output end of the servo motor, and the connecting pin corresponds to the center position of the cross.

[0011] Furthermore, the connecting piece is composed of two sleeves connected by welding, wherein the cross section of one end of the connecting shaft is cross-shaped.

[0012] Furthermore, the four ends of the cross are fixedly mounted with connecting sleeves, and an insert rod is rotatably connected between the connecting sleeve and another sleeve of the connecting piece.

[0013] Furthermore, the servo motor and the mounting plate are both fixed to the fixing frame via an integrated extension portion of the fixing frame.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The drilling mechanism of the brake disc has a total of multiple drill bits installed on the mounting disc, and circular trajectory motion is performed through connecting parts and a cross to achieve synchronous traction and rotation of the multi-axis drill bits, so that the flange hole on the brake disc can be processed in a single drilling, thereby improving the processing efficiency. At the same time, the cross is connected by a servo motor and a cam disc, which reduces the design cost of multi-axis and multi-drive and improves the practicability of the device.

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] See also Figure 1-3 A brake disc drilling mechanism in this embodiment includes a machine base 1, on which is mounted a clamping base 2 for loading and fixing the brake disc, a fixing frame 3 is fixedly mounted on the surface of the machine base 1, and a drill bit 7 for drilling is arranged on the fixing frame 3.

[0022] Specifically, by adjusting the position of the clamping seat 2 relative to the drill bit 7, the brake seat can be lifted up for drilling.

[0023] In this embodiment, a mounting plate 4 is fixedly mounted on the fixed frame 3, four rotating sleeves 5 are fixedly mounted on the mounting plate 4, a connecting shaft 6 is fixedly mounted on one end of the drill bit 7, the connecting shaft 6 passes through the rotating sleeve 5 and is slidably connected to the rotating sleeve 5, so that the drill bit 7 can rotate relative to the mounting plate 4 to drill holes.

[0024] It should be noted that a servo motor 12 for driving is fixedly mounted on the fixed frame 3, and a connecting mechanism is provided between the servo motor 12 and the connecting shaft 6 for transmitting torque. The connecting mechanism includes a connecting member 8 fixedly mounted on the connecting shaft 6 passing through one end of the rotating sleeve 5, and a cross 9 is rotatably connected between the four connecting members 8, and the cross 9 and the output end of the servo motor 12 are connected via a cam member.

[0025] The cam member in this embodiment includes a cam plate 13 fixedly mounted on the output end of the servo motor 12, and a connecting pin 14 is rotatably mounted on one end of the cam plate 13 away from the output end of the servo motor 12. The connecting pin 14 corresponds to the center position of the cross 9, so that the cam plate 13 can pull the cross 9 to rotate around the axis core position of the servo motor 12.

[0026] In this embodiment, the connecting member 8 is composed of two sleeves welded together, wherein the cross section of one end of the connecting shaft 6 is cross-shaped, so that the relative rotation between the connecting shaft 6 and the connecting member 8 is limited.

[0027] It should be noted that the four ends of the cross 9 are fixedly installed with connecting sleeves 10, and an insert rod 11 is rotatably connected between the connecting sleeve 10 and another sleeve of the connecting member 8, so that the cross 9 can drive the connecting member 8 to swing around the connecting shaft 6, thereby realizing rotational traction of the four connecting shafts 6.

[0028] It can be explained that the servo motor 12 and the mounting plate 4 are both fixed to the fixing frame 3 via the integrated extension of the fixing frame 3 , so that the cam plate 13 has enough swing space.

[0029] In another embodiment, the number of the rotating sleeves 5 and the drill bits 7 disposed on the mounting plate 4 may also be six or eight, and the corresponding cross 9 is replaced with a shape having a corresponding number of sides.

[0030] The working principle of the above embodiment is:

[0031] The drill bit 7 to be drilled is installed at the lower end of the connecting shaft 6 and extends to the position below the mounting plate 4, and the brake disc to be processed is placed on the clamp seat 2 for fixing. At the same time, the clamp seat 2 pushes the brake disc close to the drill bit 7 for drilling. The turned-on servo motor 12 drives the cam plate 13 fixedly connected on the output end to rotate. The cam plate 13 drives the center of the cross 9 to move in a circular trajectory through the connecting pin 14 at the end. The cross 9 is connected to the four connecting parts 8 through the connecting sleeve 10 at the end, thereby driving the connecting parts 8 to rotate around the outside of the connecting shaft 6, forcing several connecting shafts 6 to rotate synchronously, thereby realizing the synchronous traction of multiple drill bits 7 to drill flange holes.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0033] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
