Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of piston processing, in particular to a high-efficiency tooling for five-axis multi-angle processing of a piston. BACKGROUND

[0002] When the piston is processed by five-axis multi-angle processing, the tooling needs to be installed in the five-axis machining area first, then the piston is placed in the limiting groove of the positioning tooling, the pressure plate is fixed in the corresponding position by using the bolt to press the piston tightly, after the clamping and fixing of the piston are completed, the piston is processed by multi-angle through the flexible swing of the five-axis machine rotating shaft, the tooling will not interfere with the machining action of the five-axis machine, the multi-angle feature processing can be completed at one time, the clamping times of the piston are reduced, the auxiliary clamping time is significantly shortened, the overall processing efficiency is improved, and more importantly, the positioning error caused by multiple clamping is avoided.

[0003] For example, the patent with publication number CN211305618U discloses a five-axis machining center tooling suitable for various automobile front steering knuckles, which comprises a bottom plate, a hydraulic cylinder is arranged on the bottom plate, a positioning mandrel is arranged on the hydraulic cylinder, the upper part of the positioning mandrel has a smaller diameter than the lower part, a through hole, a positioning pin and a limiting missing groove are arranged in the center of the positioning mandrel, the positioning pin and the limiting missing groove are matched with the positioning groove and the positioning protrusion on the pressure plate respectively, the drawbar can pass through the positioning groove and the through hole in sequence from top to bottom and then be screwed with the piston rod of the hydraulic cylinder, and the pressure plate can be tightened under the drive of the hydraulic cylinder, so that the front steering knuckle is clamped, fixed blocks are arranged on the bottom plate, and a positioning plate can move forward and backward under the drive of power, the fixed blocks and the positioning plate are located on the left side and the right side of the positioning mandrel respectively, and protrusions are arranged on the side of the fixed blocks and the positioning plate close to the positioning mandrel; the present utility model effectively avoids displacement and deformation of the front steering knuckle in the processing process, and ensures the machining precision.

[0004] However, after the piston processing is completed, the tooling pressure plate needs to be removed to cancel the fixation of the piston, at this time, the debris generated in the processing process is easy to float into the installation hole of the pressure plate, which not only affects the pressing reliability of the pressure plate on the piston when clamped next time, but also directly reduces the positioning accuracy of the piston, and further causes slight shaking in the processing process of the piston, affecting the processing precision of the piston. SUMMARY

[0005] Therefore, the present application provides a high-efficiency tool for five-axis multi-angle machining of a piston, which can effectively prevent machining debris from entering the pressing plate mounting hole by forming a directional airflow barrier through the synergistic effect of a micro vortex air pump and a gas guide pipe, thereby avoiding problems such as reduced pressing reliability and positioning accuracy deviation caused by debris residue, ensuring the stability of piston positioning during subsequent clamping, eliminating piston shaking caused by inaccurate positioning during machining, ensuring the precision consistency of five-axis multi-angle machining, and realizing precise guidance of pressing plate installation through the cooperation of the guide limiting insertion hole and the guide limiting insertion plate. The corresponding design of the piston limiting groove and the piston positioning groove allows the piston to be clamped more closely. The wear-resistant clamping gasket plated with a TiN wear-resistant coating not only enhances the wear resistance of the clamping surface, prolongs the service life of the tool, but also improves the stability of clamping. In combination with the heat insulation effect of the ceramic heat insulation lining, the tool can effectively block the diffusion of heat generated during machining, thereby avoiding deformation of the tool due to temperature difference and further ensuring the positioning accuracy. The tool can also issue an alarm when the piston is not installed, thereby avoiding safety accidents caused by incorrect operation of the five-axis machine. In addition, the tool can timely remind maintenance in the event of abnormal conditions such as wear of the wear-resistant gasket, thereby preventing the production of defective products caused by tool failure. The wear-resistant clamping gasket can be individually replaced after wear, without the need for overall replacement of the tool, thereby significantly reducing the use cost and maintenance cycle. The tool can simultaneously fix multiple pistons, thereby improving the processing efficiency of the pistons.
