Description

Technical Field

[0001] This utility model relates to the field of commercial vehicle brake caliper hole processing technology, and in particular to a device for improving the processing efficiency and accuracy of commercial vehicle brake caliper holes. Background Technology

[0002] In commercial vehicles, the braking system is a critical component, requiring accurate braking in emergency situations to prevent accidents. As an important part of the vehicle braking system, the caliper plays a key role in the braking process, thus requiring higher processing technology and precision during manufacturing to ensure product stability.

[0003] During the assembly process of the clamp body, it needs to be assembled with the brake pads of the brake bracket. The 40mm diameter mounting holes at both ends of the clamp body serve as a connection, requiring a high level of assembly and fitting technology. To improve the assembly performance, the machining accuracy of the holes must be very high to ensure the stability of product processing. However, after a period of use, traditional drilling tools will have a smaller outer diameter than the initial size due to wear and other reasons. This results in the 40mm diameter mounting holes drilled at both ends of the clamp body being smaller than the actual set value. At this time, the tool needs to be replaced. However, tool replacement not only reduces processing efficiency, but also has a high cost.

[0004] To address this, we propose a device for improving the machining efficiency and precision of brake caliper body holes in commercial vehicles. Utility Model Content

[0005] The purpose of this invention is to provide a device for improving the processing efficiency and accuracy of brake caliper body holes in commercial vehicles, thereby solving or at least alleviating one or more of the aforementioned problems and other issues existing in the prior art.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] A device for improving the machining efficiency and accuracy of brake caliper holes in commercial vehicles includes a cutting head, a washer, and a bolt. The washer is frustum-shaped. A tapered groove is formed on one side of the cutting head, which fits against the outer wall of the washer. The washer is disposed in the tapered groove. A threaded groove is formed inside the cutting head, which communicates with the tapered groove. One end of the bolt passes through the washer and is threaded into the threaded groove. By tightening the bolt, the washer can move into the tapered groove, thereby increasing the outer diameter of the cutting head.

[0008] In a device according to the present invention for improving the processing efficiency and accuracy of brake caliper holes in commercial vehicles, the included angle of the top of the washer is 12°.

[0009] In a device for improving the processing efficiency and accuracy of brake caliper holes for commercial vehicles according to the present invention, a chamfer is provided at the connection between the threaded groove and the tapered groove.

[0010] In a device for improving the processing efficiency and accuracy of brake caliper holes for commercial vehicles according to the present invention, the chamfer is 30° with the horizontal direction.

[0011] The device according to this utility model for improving the processing efficiency and accuracy of brake caliper body holes in commercial vehicles also includes a handle, and the cutting head is fixedly installed at one end of the handle.

[0012] According to the present invention, a device for improving the processing efficiency and accuracy of brake caliper body holes in commercial vehicles is provided, wherein the handle has a first through hole inside, the cutter head has a connecting hole, a plugging hole and an internal cooling hole inside, the first through hole is connected to the connecting hole, the connecting hole is connected to the plugging hole, the internal cooling hole is connected to the plugging hole, and the washer has a second through hole, the internal cooling hole is connected to the second through hole.

[0013] This utility model has at least the following beneficial effects:

[0014] Improved machining accuracy: By designing a device that includes a cutting head, washer, and bolt, when the outer diameter decreases due to tool wear, tightening the bolt moves the washer into the conical groove, thereby increasing the outer diameter of the cutting head. This ensures that the assembly holes drilled at both ends of the clamp body maintain the set diameter of 40, significantly improving machining accuracy. This design effectively solves the problem of small hole diameter caused by wear of traditional drilling tools, eliminating the need for frequent tool replacements and ensuring the stability of product processing.

[0015] Improved machining efficiency: Since the outer diameter of the tool can be restored by adjusting the shims after tool wear without replacing the entire tool, the time interrupted by tool replacement is greatly reduced, which significantly improves machining efficiency. This not only helps to reduce production costs, but also shortens the production cycle and improves overall production efficiency.

[0016] Reduced maintenance costs: The tool can be restored to its working condition with simple adjustments, extending its service life and thus reducing maintenance costs;

[0017] The structure is ingenious and easy to operate: the washer is set in the shape of a frustum, which fits perfectly with the conical groove on the cutter head. The outer diameter can be adjusted by tightening the bolt, making the operation simple and quick.

[0018] By creating interconnected through holes and internal cooling holes in the handle, cutter head, and washers, effective cooling of the cutting tool is achieved. Coolant spraying is provided during machining to cool and lubricate, further improving machining accuracy and tool life. Attached Figure Description
