Description

Technical Field

[0001] The utility model relates to the technical field of brake disc processing equipment, in particular to an integrated processing tooling for wheel-mounted brake discs. Background Art

[0002] The brake disc is a friction couple of a disc brake. In addition to having the strength and stiffness required as a component, it should also have as high and stable a friction coefficient as possible, as well as appropriate wear resistance, heat resistance, heat dissipation, and heat capacity, etc.

[0003] During the processing of wheel-mounted brake discs, it is often necessary to machine heat dissipation rib grooves on one surface of the brake disc, and at the same time, it is also necessary to drill and expand holes on the opposite surface. Therefore, in the actual operation process, generally, one surface is machined on the machine first. After the machining is completed, the workpiece is taken off the machine. After changing to the other surface, it is put on the machine again for machining. The operation is complex, the processing efficiency is low, and there is also a risk of low processing accuracy in the two clamping operations. Once there is a clamping deviation, the concentricity of the two surfaces will be reduced. Summary of the Utility Model

[0004] An embodiment of the present application provides an integrated processing tooling for wheel-mounted brake discs, which can complete the processing of two surfaces with only one clamping, can reduce the time of loading and unloading the machine, improve the work efficiency, and at the same time can ensure the processing accuracy of the two surfaces.

[0005] An embodiment of the present application provides an integrated processing tooling for wheel-mounted brake discs, including a rotating mechanism and a fixing mechanism. The rotating mechanism includes a rotating table, a rotating tailstock, and a bridge plate. The rotating table and the rotating tailstock are relatively distributed in the same height direction. The bridge plate is vertically connected between the rotating end of the rotating table and the rotating tailstock in a suspended manner.

[0006] The fixing mechanism includes a tensioning element and a plurality of telescopic elements. The tensioning element is installed on one side of the bridge plate and is located in the middle of the bridge plate. The tensioning end of the tensioning element vertically penetrates the bridge plate. A plurality of the telescopic elements are symmetrically distributed on the other side of the bridge plate and are close to the outer edge of the bridge plate. The telescopic ends of the telescopic elements are all facing the tensioning end. The bridge plate is provided with an avoidance hole for avoiding the position to be processed.

[0007] In a possible implementation manner, the rotating table is implemented as a four-axis turntable.

[0008] In a possible implementation manner, adapter plates are symmetrically installed at the rotating end of the rotating table and the rotating tailstock. Horizontally extending support plates are symmetrically arranged on the opposite surfaces of the two adapter plates. The bridge plate connects the surfaces of the two support plates on the same side.

[0009] In a possible implementation, the tensioning element is implemented as a core-expanding oil cylinder.

[0010] In a possible implementation, the telescopic element is implemented as a clamping oil cylinder, and there are six telescopic elements.

[0011] In a possible implementation, a clamping pad is installed at the telescopic end of the telescopic element. The clamping pad is provided with an L-shaped structure at one end close to the tensioning end so as to be able to tightly press the brake disc synchronously on the upper side when clamping the brake disc.

[0012] In a possible implementation, the rotating mechanism further includes a bottom plate, and both the rotating table and the rotating tailstock are connected to the bottom plate through pads at the bottom.

[0013] Beneficial effects: Compared with the prior art, the integrated processing tooling for wheel-mounted brake discs provided by the present application fixes the brake disc through the bridge plate in cooperation with the tensioning element and the telescopic element. At the same time, avoidance holes are provided on the bridge plate. When one surface of the brake disc is processed, the bridge plate is rotated to the other surface through the rotating table in cooperation with the rotating tailstock, and the other surface opposite to the brake disc can be directly processed. During this period, the brake disc does not need to be disassembled. Therefore, the processing of two surfaces of the brake disc can be completed simultaneously through one clamping, thereby improving the working efficiency. At the same time, one clamping can also ensure the processing accuracy and avoid the problem of affecting the processing accuracy due to inconsistent clamping positions of the two surfaces.

[0014] These and other objects, features and advantages of the present utility model are fully embodied through the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the above terms should not be construed as a limitation to the present utility model.

[0019] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of this element can be multiple. The term "one" should not be construed as a limitation to the quantity.

[0020] Reference Figure 1 and Figure 2 Referring to and, an integrated processing tool for wheel-mounted brake discs provided by an embodiment of the present application includes a rotating mechanism and a fixing mechanism. The rotating mechanism includes a rotating table 10, a rotating tailstock 20, and a bridge plate 30. The rotating table 10 and the rotating tailstock 20 are both implemented as four-axis turntables, such as 400 servo turntables. The rotating table 10 and the rotating tailstock 20 are distributed relatively in the same height direction. At the same time, the bridge plate 30 is vertically connected between the rotating end of the rotating table 10 and the rotating tailstock 20 in a suspended manner, so that the bridge plate 30 can be driven to flip by the cooperation of the rotating table 10 and the rotating tailstock 20.

[0021] The fixing mechanism includes a tensioning element 40 and a plurality of telescopic elements 50. The tensioning element 40 is installed on one side of the bridge plate 30 and is located in the middle of the bridge plate 30. At the same time, the tensioning end of the tensioning element 40 vertically penetrates the bridge plate 30 and is used for centering in the inner hole of the brake disc 60 to preliminarily fix the brake disc 60 in a tensioning manner. The plurality of telescopic elements 50 are symmetrically distributed on the other side of the bridge plate 30 and are close to the outer edge of the bridge plate 30. At the same time, the telescopic ends of the telescopic elements 50 are all facing the tensioning end, so as to be able to clamp and fix the brake disc 60 on the outer circumference. In addition, the bridge plate 30 is provided with an avoidance hole for avoiding the position to be machined.

[0022] The operation steps are roughly as follows:

[0023] Drive the bridge plate 30 to flip through the cooperation of the rotating table 10 and the rotating tailstock 20 to keep the bridge plate 30 horizontal, and at the same time, the tensioning element 40 is located at the bottom of the bridge plate 30.

[0024] Place the brake disc 60 on the bridge plate 30, tighten it through the tightening end of the tightening element 40 in the inner hole of the brake disc 60 to center it, and then control the telescopic element 50 to synchronously extend its telescopic end to clamp the brake disc 60 on the outside. In this way, the brake disc 60 is fixed on the bridge plate 30 through the cooperation of the bridge plate 30, the tightening element 40 and the telescopic element 50, and the movement of the brake disc 60 during the machining process is prevented;

[0025] After the first surface of the brake disc 60 is machined, the rotary table 10 drives the bridge plate 30 to flip to the opposite surface, and then the second surface of the brake disc 60 is machined. During this period, the brake disc 60 does not need to be disassembled. Thus, the machining of the two surfaces of the brake disc 60 can be completed simultaneously by one-time clamping, with high working efficiency. At the same time, one-time clamping can also ensure the machining accuracy and avoid the problem of affecting the machining accuracy due to inconsistent clamping positions of the two surfaces.

[0026] The tightening element 40 is implemented as a core tightening oil cylinder. The telescopic element 50 is implemented as a clamping oil cylinder, and there are six telescopic elements 50 symmetrically distributed on the outer edge of the bridge plate 30.

[0027] In one embodiment, adapter plates 11 are symmetrically installed at the rotating end of the rotary table 10 and the rotating tailstock 20. At the same time, on the opposite surfaces of the two adapter plates 11, support plates 12 extending in the horizontal direction are symmetrically arranged, and the bridge plate 30 is connected to the surfaces of the two support plates 12 on the same side. Thereby, the contact area with the bridge plate 30 can be increased, the structural connection strength between the rotary table 10, the rotating tailstock 20 and the bridge plate 30 can be improved, and the bridge plate 30 can be supported by the support plates 12 when the bridge plate 30 is located on top of the support plates 12.

[0028] In one embodiment, a clamping pad 51 is installed at the telescopic end of the telescopic element 50. The clamping pad 51 is provided with an L-shaped structure 52 at one end close to the tightening end, so as to be able to tightly press the brake disc 60 on the upper side when clamping the brake disc 60, thereby further ensuring the stability and firmness of the telescopic element 50 clamping the brake disc 60 and avoiding longitudinal movement and lateral movement during the machining process.

[0029] In one embodiment, the rotating mechanism further includes a bottom plate 70. The rotary table 10 and the rotating tailstock 20 are both connected to the bottom plate 70 through pads 13 at the bottom, making this tooling an integral tooling, which is convenient for movement and use. In addition, the consistency of the heights of the rotary table 10 and the rotating tailstock 20 can be ensured through the pads 13, and further the levelness of the bridge plate 30 and the machining accuracy of the brake disc 60 can be ensured.

[0030] It should be noted that the terms "first, second" in the present application are only used for descriptive purposes and do not indicate any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.

[0031] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention.
