Description

Technical Field

[0001] The utility model relates to the technical field of fixed clamping tools, in particular to a fixed clamping tool for drilling piston pin seats. Background Technique

[0002] The piston pin seat is a structure on the piston that supports the piston pin. The piston pin can rotate freely within the piston pin seat, and there is lubricating oil between the two. When the piston works, the combustion gas pressure acts uniformly on the piston top, while the supporting reaction force given by the piston pin acts on the piston pin seat at the piston skirt, transmitting the force to the connecting rod, thereby driving the crankshaft to rotate. The top of the piston is affected by the gas pressure (i.e., the maximum combustion pressure). The piston transmits the force to the pin through the pin hole located within the pin seat, and the pin then transmits the acting force to the connecting rod, and finally to the crankshaft to be converted into rotational motion. To ensure the normal operation of the motion mechanism, the piston, pin, connecting rod, and crankshaft must all have sufficient strength and wear resistance. During the processing of the piston pin seat, a drilling operation is required.

[0003] A Chinese patent discloses a drilling processing device for piston pin seats. The patented technology includes a positioning disk. A limiting step is provided on the bottom end surface of the positioning disk. At the same time, two drill bushings are symmetrically arranged on the positioning disk. A connecting plate is provided on the bottom end surface of the positioning disk. The central axis of the connecting plate passes through the center of the positioning disk. Two groups of adjusting mechanisms are symmetrically arranged at the bottom end of the connecting plate. The adjusting mechanism includes two symmetrically distributed guide rods. The ends of the two guide rods are simultaneously movably connected to the top plate. Springs are also sleeved on the guide rods, and the springs are abutted between the connecting plate and the top plate.

[0004] However, during the use of the above-mentioned processing device, it is not easy to quickly fix and clamp the piston pin seat to be drilled, which affects the drilling efficiency. Therefore, those skilled in the art have provided a fixed clamping tool for drilling piston pin seats to solve the problems raised in the above background technique. Content of the Utility Model
