Description

A fixture for an automobile connecting rod boring machine

technical field

The utility model relates to the field of automobile connecting rod processing, more specifically, it relates to a clamp used for an automobile connecting rod boring machine.

Background technique

A boring machine is a machine tool that mainly uses a boring tool to bore an existing prefabricated hole in a workpiece. It is divided into horizontal boring machines, floor boring and milling machines, diamond boring machines and coordinate boring machines. Usually the main motion is the rotation of the boring tool, and the movement of the boring tool or the workpiece is the feed motion. It is mainly used to process high-precision holes or complete the finishing of multiple holes at one time. In addition, it can also process other processing surfaces related to hole finishing. The machining accuracy and surface quality of drilling, milling, and cutting are higher than those of drilling machines by using different tools and accessories.

The connecting rod is one of the main transmissions of the automobile engine. It connects the piston and the crankshaft. Its function is to convert the reciprocating motion of the piston into the rotational motion of the crankshaft, and transmit the force acting on the piston to the crankshaft to output power. The connecting rod is divided into a large end and a small end. During processing, the large end of the connecting rod often needs to be cut into two sections, one is the rod body connected to the small end of the rod body, and the other is cut to form an arc. Rod body two is convenient for subsequent fixing of the connecting rod on the crankshaft. The cutting direction of the connecting rod is generally vertical to the length of the connecting rod and cut vertically downward to the length of the connecting rod. However, both cutting methods divide the inner ring of the big end of the connecting rod into two parts . There are two sockets symmetrically arranged on the connecting rod. The axis direction of the two sockets is always perpendicular to the cutting direction of the big end of the connecting rod. At the same time, the two sockets are divided into two sections by the first rod body and the second rod body. Internal threads need to be provided in the jacks, which are used to thread the bolts to fix rod body one and rod body two. Therefore, the socket of the rod body 1 needs to be bored with a boring machine to bore out the internal thread matched with the bolt external thread, so as to fix the rod body 1 and the rod body 2.

And existing boring machine generally is that the connecting rod to be processed is fixed on the frame by vise when working, and then is processed. However, when processing automotive connecting rods, it is often not possible to directly fix the connecting rod to the bracket through a vise for processing. It needs to be assisted by other fixing parts, which is time-consuming and laborious. Therefore, a special tool is required for fixing the connecting rod to the bracket for processing. fixture.
