Description

Technical Field

[0001] This utility model relates to the field of brake disc processing technology, specifically a brake disc processing fixture. Background Technology

[0002] Brake disc machining fixtures are a type of specialized fixture used in the production of brake discs to position, clamp, and assist in the machining of workpieces. Through precise positioning and stable clamping, they ensure the geometric accuracy and consistency of the machined surfaces of the brake discs, while improving production efficiency and reducing manual adjustment costs. These specialized process equipment, designed specifically for brake discs, achieve efficient positioning, rotary machining, and anti-deviation functions through a combination of mechanical and magnetic structures.

[0003] Referring to the existing Chinese patent with publication number CN222920051U, a fixture for processing brake discs is disclosed, which relates to the field of brake disc processing technology. The fixture includes a brake disc, a limiting mechanism is provided on the inner side of the brake disc, and an auxiliary fixing mechanism is provided on the left side below the limiting mechanism. The inner wall of the brake disc abuts against a top block. The limiting mechanism includes a first outer shell, the inner wall of the first outer shell is connected to a threaded rod by a thread, the right end of the threaded rod is rotatably connected to a slider by a bearing, the outer wall of the slider is slidably connected to two limiting plates, and the left side of each limiting plate is fixedly connected to the first outer shell.

[0004] The aforementioned brake disc machining fixture aligns the brake disc's axis with the axis of the first housing. A support block is inserted into the slot, and the operator places the brake disc on the support rod. This eliminates the need for the operator to repeatedly rotate the brake disc or constantly hold it, saving labor. The forward rotation of the threaded rod drives the slider, causing multiple sliding rods to slide synchronously outward along the inclined grooves machined on the slider. This means that when fixing the brake disc, the operator only needs to rotate one screw to move multiple top blocks synchronously outward, which is faster than rotating multiple bolts, thus improving work efficiency. However, this brake disc machining fixture still has some drawbacks. It relies on a single threaded rod to drive the synchronous slider, lacks a real-time clamping force monitoring and feedback mechanism, and is prone to deformation of thin-walled brake discs. Manual alignment of the brake disc and fixture axis is required, and the lack of an integrated automatic alignment mechanism means that human error significantly reduces machining consistency. Therefore, we need to propose a brake disc machining fixture. Utility Model Content

[0005] The purpose of this invention is to provide a brake disc processing fixture with the advantages of clamping force feedback and automatic centering mechanism, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a brake disc machining fixture, comprising a housing, a fixing mechanism for fixing the inner ring of the brake disc being provided on the outside of the housing, a connecting mechanism for connecting the fixing mechanism being provided on the inner wall of the housing, a closing mechanism for closing the housing being provided at one end of the housing, an installation mechanism for mounting a lathe jaws being provided at the end of the housing away from the closing mechanism, and a detection mechanism for detecting pressure when fixing the inner ring of the brake disc being fixed being provided on the surface of the fixing mechanism.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5This utility model provides a technical solution: a brake disc processing fixture, including a housing 1, with a fixing mechanism on the outside of the housing 1 for fixing the inner ring of the brake disc; the fixing mechanism includes a support plate 2, which is disposed outside the housing 1, with a baffle 3 on the surface of the support plate 2, a rubber plate 4 on the top of the support plate 2, and a servo electric cylinder 5 below the support plate 2 and connected to its output end. The servo electric cylinder 5 pushes the support plate 2 to expand radially, causing the rubber plate 4 to contact the inner ring of the brake disc.

[0025] The inner wall of the outer casing 1 is provided with a connecting mechanism for connecting the fixing mechanism; the connecting mechanism includes a dovetail block 6, which is disposed on the inner wall of the outer casing 1. A mounting plate 7 is provided on one side of the dovetail block 6, and dovetail grooves 8 are provided on both sides of the mounting plate 7 and are adapted to the dovetail block 6. The bottom of the servo electric cylinder 5 is connected to the mounting plate 7. The sliding pair between the dovetail block 6 and the dovetail grooves 8 ensures that multiple support plates move synchronously and an automatic centering brake disc is activated.

[0026] One end of the outer casing 1 is provided with a sealing mechanism for closing the outer casing 1; the sealing mechanism includes a sealing plate 9, which is disposed at one end of the outer casing 1. The surface of the sealing plate 9 has a mounting hole 10 that penetrates the outer casing 1 and extends into the interior of the outer casing 1. A screw 11 is disposed inside the mounting hole 10. The sealing plate 9 prevents cutting debris from entering the interior of the outer casing. Loosening the screw 11 allows the sealing plate 9 to be removed, facilitating maintenance of the internal mechanism.

[0027] The outer casing 1, at the end furthest from the sealing mechanism, is provided with a mounting mechanism for mounting lathe grippers. The mounting mechanism includes a mounting block 12, which is located at the end of the outer casing 1 furthest from the sealing plate 9. The surface of the mounting block 12 is provided with anti-slip grooves 13. The lathe grippers clamp the end of the outer casing 1 through the anti-slip grooves 13 of the mounting mechanism, forming a rigid connection.

[0028] The surface of the fixing mechanism is equipped with a detection mechanism for detecting pressure when fixing the inner ring of the brake disc. The detection mechanism includes a placement hole 14, which is formed on the surface of the rubber plate 4, penetrates the rubber plate 4, and extends into the interior of the support plate 2. A pressure sensor 15 is installed inside the placement hole 14. The pressure sensor 15 provides real-time feedback of the clamping force to the controller, realizing closed-loop force control. When the brake disc is placed on the surface of the rubber plate 4, the output end of the servo cylinder 5 extends and pushes the support plate 2, causing the rubber plate 4 to contact the inner wall of the brake disc. The pressure sensor 15 detects the pressure pressing against the inner wall of the brake disc and transmits it to the controller via an electrical signal. The controller controls the extension length of the output end of the servo cylinder 5. This prevents deformation of the thin-walled brake disc and significantly improves the processing yield.

[0029] A controller is provided on the surface of the mounting plate 7, and the controller is electrically connected to the servo cylinder 5 and the pressure sensor 15.
