Description

Technical Field

[0001] The utility model relates to the technical field of brake disc processing equipment, in particular to a novel brake disc drilling fixture. Background Art

[0002] Brake discs are the most critical safety component. Their replacement is closely tied to driving habits. Hard braking wears out the discs the most. Factors influencing braking force are the size and type of discs. When a driver encounters an emergency and steps on the brake pedal, the brake fluid in the oil pipe is pushed. Ultimately, the fluid is pushed to the brake caliper, which squeezes the disc to create braking force, ultimately achieving deceleration or stopping. Therefore, the brake disc is the final link in the "compression" process that generates braking force, and its importance is undeniable.

[0003] The brake disc is part of the brake assembly, and its assembly is inseparable from the processing quality and precision of the fitting surface. In addition to having the strength and rigidity required as a component, the friction couple of the disc brake should also have the highest possible and stable friction coefficient, as well as appropriate wear resistance, heat resistance, heat dissipation and heat capacity. To achieve a stable friction coefficient, the surface roughness of the braking surface and the stability of the texture are essential. To better demonstrate the performance of the brake disc, the fitting accuracy during the assembly process must not be lost.

[0004] During the machining of brake discs, it is difficult to control the fit of the assembly surface. The fit of the assembly surface and the machining quality of the assembly holes on the fitting surface are inseparable from the stability of the machining process. Currently, the clamping of the brake disc during the drilling process is unstable, which will cause the brake disc surface tool to easily vibrate and need to be replaced. However, the actual life of the tool has not yet expired, resulting in a waste of tool costs and low efficiency. In addition, the current brake disc machining still has the following problems:

[0005] 1. The brake disc drilling fixture is a special fixture for a product. It needs to be disassembled when changing the model, which makes the change slow.

[0006] 2. When drilling the brake disc, there are many iron chips, which are easy to accumulate around the fixture, making it difficult to clean and requiring a long maintenance time.

[0007] To meet the needs of the modern machinery industry's development towards high-end, precision, and cutting-edge technology, as well as the characteristics of multi-brand, small-batch production, modern production and processing technology is developing in the direction of precision, efficiency, flexibility, and standardization. To this end, we provide a new brake disc drilling fixture. Utility Model Content

[0008] The utility model aims to provide a novel brake disc drilling fixture, which solves the problems of easy accumulation of iron cuttings around the fixture and slow mold change during the processing of the existing brake disc.

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new brake disc drilling fixture, comprising a base, a triangular slide inclined along the top to the front and rear sides is installed on the base, a center positioning fixture is detachably installed at the center of the triangular slide, and a support mechanism and a clamping assembly are also detachably installed around the center positioning fixture on the triangular slide, the clamping assembly comprises a hydraulic cylinder, a clamping arm, an upper clamping block and a lower clamping mechanism, the hydraulic cylinder and the lower clamping mechanism are both fixed to the triangular slide in the vertical direction, one end of the clamping arm is detachably fixed to the telescopic end of the hydraulic cylinder, and the other end of the clamping arm is fixed to the upper clamping block, the bottom surface of the upper clamping block and the top surface of the lower clamping mechanism correspond to each other to form a clamping surface and are clamped on the outer edge end surface of the brake disc, and the center hole of the brake disc is installed corresponding to the center positioning fixture, and the support mechanism is supported on the outer edge end surface of the brake disc.

[0010] Preferably, the support mechanisms are symmetrically arranged in at least two groups with the axis of the center positioning fixture as the symmetry axis, and the support mechanisms and the clamping components are staggered in the circumferential direction of the center positioning fixture.

[0011] Preferably, the clamping components are symmetrically arranged in at least two groups with the axis of the central positioning fixture as the symmetry axis.

[0012] Preferably, the center positioning fixture includes a fixed column mounted on a triangular slide, a supporting column supporting an edge end surface of the center hole of the brake disc, and a convex column mounted with the center hole of the brake disc.

[0013] Preferably, the center positioning fixture, the supporting mechanism and the lower clamping mechanism are all detachably fixed to the triangular slide by bolts, and the clamping arm is detachably fixed to the telescopic end of the hydraulic cylinder by a nut.

[0014] Preferably, the triangular slide is provided with an assembly hole type that is adapted to the shape of the center positioning fixture, the support mechanism and the clamping assembly.

[0015] Preferably, the concave inner assembly surface of the brake disc is mounted upward on a center positioning fixture.

[0016] The utility model has the following beneficial effects:

[0017] 1. The brake disc is positioned and supported by a center positioning fixture, further supported by a supporting mechanism, and stably clamped by a clamping assembly. Support is provided at the center and edge of the brake disc, and multi-directional support and fixation ensure the stability of the brake disc during processing;

[0018] 2. When improving the design of the fixture, the outline of the fixture is enlarged to take into account the positioning and clamping methods of all brake discs. Only the center positioning fixture, support mechanism, lower clamping mechanism, clamping arm and the upper clamping block on it need to be replaced, which greatly improves the changeover efficiency;

[0019] 3. When designing the fixture, we took into account that iron chips are prone to accumulation, so the entire shape was changed to a triangular slide. After processing, the iron chips can slide directly into the chip discharge port of the equipment, reducing maintenance time while ensuring the normal operation of the fixture.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-2As shown, the utility model provides a technical solution: a new brake disc drilling fixture, comprising a base 1, a triangular slide 2 is installed on the base 1, which is inclined to the front and rear sides along the top, and a center positioning fixture 3 is detachably installed in the center of the triangular slide 2. The center positioning fixture 3 includes a fixed column 31 installed on the triangular slide 2, a support column 32 supporting the edge end face of the center hole of the brake disc 6, and a convex column 33 installed with the center hole of the brake disc 6. A supporting mechanism 4 and a clamping assembly 5 are also detachably installed around the center positioning fixture 3 on the triangular slide 2. The supporting mechanism 4 is symmetrically arranged in at least two groups with the axis of the center positioning fixture 3 as the symmetry axis, and the supporting mechanism 4 and the clamping assembly 5 are staggered circumferentially on the center positioning fixture 3. The clamping assembly 5 is symmetrically arranged in at least two groups with the axis of the center positioning fixture 3 as the symmetry axis. The clamping assembly 5 includes a hydraulic cylinder 51, a clamping arm 52, an upper clamping block 53 and a lower clamping mechanism 54. The hydraulic cylinder 51 and the lower clamping mechanism 54 are both fixed on the triangular slide 2 in the vertical direction. One end of the clamping arm 52 is detachably fixed to the telescopic end of the hydraulic cylinder 51, and the other end of the clamping arm 52 is fixed to the upper clamping block 53. The bottom surface of the upper clamping block 53 and the top surface of the lower clamping mechanism 54 correspond to each other to form a clamping surface and are clamped on the outer edge end surface of the brake disc 6, and the center hole of the brake disc 6 is installed corresponding to the center positioning fixture 3, and the supporting mechanism 4 is supported on the outer edge end surface of the brake disc 6, and the concave inner assembly surface of the brake disc 6 is upwardly mounted on the center positioning fixture 3;

[0025] The center positioning fixture 3, the supporting mechanism 4 and the lower clamping mechanism 54 are all detachably fixed to the triangular slide 2 by bolts 7, and the clamping arm 52 is detachably fixed to the telescopic end of the hydraulic cylinder 51 by nuts 8. When changing the model, it is only necessary to remove the bolts 7 and nuts 8 to replace the center positioning fixture 3, the supporting mechanism 4 and the lower clamping mechanism 54 and the clamping arm 52 and the upper clamping block 53 thereon, which greatly improves the model changing efficiency. The triangular slide 2 is provided with an assembly hole type that is adapted to the shape of the center positioning fixture 3, the supporting mechanism 4 and the clamping component 5. Combined with the inclined surfaces on the front and rear sides of the triangular slide 2, iron cuttings are not easily accumulated on the triangular slide 2. After processing, the iron cuttings can be directly slid into the cutting outlet of the equipment, which reduces maintenance time while ensuring the normal operation of the fixture.
