Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, in particular to a multi-hole processing fixture for a brake disc. Background Art

[0002] The brake disc is a friction pair of a disc brake and a component in the brake system that generates braking force to hinder the movement or movement trend of a vehicle. It has a general frictionless boosting effect, that is, the performance is relatively stable, the performance is less reduced after water ingress, and the size and weight are smaller than those of a drum brake under the same output braking torque. It is easier to achieve automatic clearance adjustment and other advantages. During the production and processing of the brake disc, holes need to be drilled on the surface of the brake disc so that the brake disc can be connected to other structures during installation. When drilling holes in the brake disc, a fixture needs to be used to clamp the brake disc to ensure the accuracy of the drilling position and the stability of the processing process. However, it still has the following disadvantages in actual use:

[0003] The utility model with publication number CN219444266U discloses a brake disc processing fixture, wherein the support mechanism includes a base, a rotating assembly is arranged inside the base, the rotating assembly includes a motor, a reducer is arranged at the output end of the motor, a rotating table is arranged on the side of the reducer away from the motor, a magnet block is embedded on the upper surface of the rotating table, and the fixture is mostly used for clamping and positioning on both sides of the brake disc, but the position and size of the fixture will affect the movement and operation of the drilling equipment. After one hole is processed, the brake disc needs to be rotated to process another hole, and the operation is relatively cumbersome;

[0004] When processing a brake disc, it is often necessary to place the brake disc on a base for operation. However, when drilling holes in the brake disc, the drilling equipment and the base are easily worn due to improper operation, which increases maintenance costs. Utility Model Content

[0005] The utility model aims to provide a multi-hole processing fixture for a brake disc, which solves the problem that in actual use of the brake disc processing fixture, the position and size of the fixture will affect the movement and operation of the drilling equipment, resulting in the need to move the brake disc after processing a hole, which is a relatively cumbersome operation. During the processing of the brake disc placed on a base for drilling, the drilling equipment and the base may be worn due to improper manual operation, thereby affecting subsequent use.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a multi-hole processing fixture for a brake disc, comprising a positioning box and a support plate, wherein a positioning opening is provided on the top of the positioning box, an exhaust fan is fixedly connected to the bottom of one side of the positioning box, support plates are slidably connected to the positioning opening on all sides, an air pump is fixedly connected to the bottom of each support plate, and a limiting cylinder is provided on one side of each support plate away from the center of the positioning box;

[0008] When drilling a hole in the brake disc, the brake disc is placed inside the positioning port, and the edge of the brake disc is supported and limited by multiple support plates to ensure the stability of the brake disc during processing, without blocking the surface of the brake disc, and facilitating the operation of the drilling equipment. When the drilling equipment is drilling, even if the operator operates improperly, causing the drilled workpiece to penetrate the surface of the brake disc, it will not cause wear to the drilling equipment and processing fixtures, avoiding affecting subsequent processing. The exhaust fan can drive the outside air to flow into the positioning port, so that the debris generated during drilling can be collected in the The waste box will not cause pollution to the environment, and can cool down the processing fixture and brake disc to avoid deformation of the brake disc caused by excessive temperature. The air between the brake disc and the support plate can be extracted by the air pump, and the brake disc is pressed against the top of the support plate by air pressure to ensure the stability of the processing process. The support plate can be driven to move and limit the edge of the brake disc by the limit cylinder, so that the processing fixture can quickly position brake discs of different sizes. There is no need to consider the thickness of the brake disc during the clamping process. The loading and unloading operations are simple and convenient, which improves the processing efficiency.

[0009] Furthermore, a control assembly is clamped and fixed on one side of the positioning box, anti-skid pads are clamped and fixed around the bottom of the positioning box, and sliding grooves are provided around the positioning opening;

[0010] The clamp can be controlled by the control component, so that the staff only needs to set the size of the brake disc to be processed, and after the brake disc is placed on the upper side of the support plate, the air pump is controlled by the control component again to make the brake disc adsorbed on the upper side of the support plate, thereby completing the clamping of the brake disc. The operation is simple and convenient.

[0011] Furthermore, a slot is provided on one side of the positioning box, the slot is connected to the positioning port, a filter element is connected to one side of the slot, a waste box is connected to the other side of the slot, one end of the filter element is connected to one side of the waste box, and the exhaust fan is connected to the waste box through the filter element;

[0012] When the drilling equipment is drilling a hole in the brake disc, the exhaust fan draws air from the waste box, and the outside air is drawn into the waste box through the positioning port, driving the debris generated by the drilling into the waste box to prevent the debris generated by the drilling from polluting the environment. The flowing air can cool the brake disc to prevent the brake disc from overheating and easily deforming. The air can be filtered through the filter element and the filtered air is discharged, while the debris is retained in the waste box, which is convenient for centralized processing of the debris.

[0013] Furthermore, a limiting frame is welded and fixed on one side of the top of each support plate, a telescopic tube is clamped on one side of the limiting frame, the telescopic tube is slidably clamped on one end of the limiting cylinder, one of the support plates and the limiting frame is slidably plugged into the inner side of a slide groove, and one of the limiting cylinders is clamped on the inner side of a slide groove;

[0014] The movement of the telescopic tube is driven by the limit cylinder, which further drives the movement of the support plate and the limit frame, so that brake discs of different sizes can be supported and limited, thereby improving the flexibility of the use of the fixture, and the fixture can be clamped and positioned at the edge of the brake disc without blocking the upper surface of the brake disc, thereby facilitating the operation of the drilling equipment. When the drilling equipment is drilling, even if the staff operates improperly, causing the drilled workpiece to penetrate the surface of the brake disc, it will not cause wear to the drilling equipment and the processing fixture, thereby avoiding affecting subsequent processing.

[0015] Furthermore, a sealing gasket is clamped and fixed on one side of the top of each support plate, and an air extraction pipe is clamped through the top of each air pump, and the air extraction pipe is clamped through the bottom of the support plate, the air extraction pipe is located on the inner side of the sealing gasket, and the sealing gasket is located on the other side of the support plate relative to the limiting frame;

[0016] After the brake disc is placed on the upper side of the support plate and limited by the limit frame, air is pumped between the brake disc and the sealing pad through an air pump, so that the brake disc is tightly attached to the support plate and the upper side of the sealing pad under the action of air pressure, ensuring the stability of the brake disc during processing.

[0017] The utility model has the following beneficial effects:

[0018] The utility model solves the problem that most clamps are clamped and positioned on both sides of the brake disc, but the position and size of the clamp will affect the movement and operation of the drilling equipment. After one hole is processed, the brake disc needs to be rotated in order to process another hole, which is a cumbersome operation. When drilling the brake disc, the limit cylinder is controlled according to the size of the brake disc to drive the support plate to a suitable position, the brake disc is placed on the upper side of the four support plates, the limit frame is fitted to the edge of the brake disc to limit it, and the air pump is controlled to evacuate air between the brake disc and the sealing pad, so that the brake disc is tightly attached to the upper side of the support plate and the sealing pad, thereby completing the clamping and positioning of the brake disc, and the clamp is clamped and positioned at the edge of the brake disc, without blocking the upper surface of the brake disc, which is convenient for the operation of the drilling equipment.

[0019] The utility model solves the problem that when processing the brake disc, the brake disc often needs to be placed on a base for operation, but the drilling equipment and the base are easily worn due to improper operation when drilling the brake disc, thereby increasing maintenance expenses. After the brake disc is clamped and positioned by the support plate, the support plate is located at the edge of the brake disc, and the center of the brake disc is suspended in the positioning port. When the brake disc is drilled by the drilling equipment, even if the staff operates improperly, causing the drilled workpiece to penetrate the surface of the brake disc, it will not cause wear to the drilling equipment and the processing fixture, thereby avoiding affecting subsequent processing.
