Description

Technical Field

[0001] The utility model relates to the technical field of camshaft processing, in particular to a clamp for camshaft processing. Background Art

[0002] The camshaft is an important component in the internal combustion engine. It is responsible for controlling the opening and closing time of the valve, thereby controlling the flow of gas in and out of the cylinder, affecting the performance and efficiency of the engine. The camshaft processing fixture is a device used to fix and position the camshaft for processing. This fixture is usually made of high-strength metal, such as steel or aluminum alloy, to ensure sufficient rigidity and durability, to ensure that the camshaft is firmly fixed during the processing process to avoid processing errors and damage, and to provide accurate positioning to ensure processing accuracy and consistency.

[0003] Patent document CN219881857U discloses a clamp for automobile camshaft processing, "which includes: a clamp body, the side surface of which is detachably connected to a first support plate by screws, and the upper surface of the clamp body is provided with a main clamping assembly; a secondary clamping assembly, the secondary clamping assembly includes a threaded rod, a clamping piece, a locking rod and an external member, the threaded rod is threadedly connected to the first support plate, the clamping piece is fixedly connected to one end of the threaded rod, a threaded hole is provided on the upper surface of the clamping piece, and the locking rod is threadedly connected in the threaded hole, and the external member is fixedly connected to one end of the threaded rod away from the clamping piece. By setting the secondary clamping assembly, the main clamping assembly is matched with the clamping assembly. By using the clamp, the middle and end parts of the camshaft workpiece can be clamped, ensuring that the clamp can firmly clamp the camshaft workpiece, avoiding affecting the processing tightness of the camshaft workpiece by the external processing device", however, the clamp for automobile camshaft processing in the above-mentioned public document mainly considers improving the clamping of the middle and end parts of the camshaft workpiece, ensuring that the clamp can firmly clamp the camshaft workpiece, without considering that the disassembly and assembly of the clamp is relatively complicated, and the staff needs to use tools to disassemble and assemble the clamp. The complicated disassembly and assembly process will affect the production process, thereby increasing the production cycle and reducing the production efficiency. Therefore, it is necessary to develop a camshaft processing clamp that can quickly disassemble and assemble the clamp. Utility Model Content
