Problems solved by technology

[0002] There are many ways to make connecting rods, but there are some problems, such as insufficient strength of connecting rods, insufficient hole precision of connecting rods, and overall shape of connecting rods that do not meet the requirements, etc. Such connecting rods cannot meet the needs of the market. Demand is not conducive to the smooth progress of production, so in order to better meet the requirements of the connecting rod, a processing method is proposed to solve this problem

Abstract

The invention discloses a machining technology of a connecting rod. The machining technology of the connecting rod comprises the steps of: step 1, cutting a material by using a laser cutting machine to cut out the outline of the product preliminarily, wherein the product is 315 mm in length, 65 mm in width and 25 mm in thickness; step 2, performing further finish machining on the well-cut product by using a milling machine, performing finish machining the size according to drawing requirements until the length is 208+ / -0.2 mm, the width is 60+ / -0.1 mm and the thickness is 20+ / -0.1 mm; step 3, performing chamfering process on the four corners of the material, wherein the chamfering size is 17.5 mmX45 degrees; step 4, performing rounding process at the joint after the chamfering is finished, and chamfering a R5 circular bead; step 5, performing surface polishing on the finished product until the surface roughness is Ra3.2; step 6, performing stress treatment on the finished product; step 7, inspecting the product and putting the product into a warehouse. By virtue of outline cutting by the laser cutting machine, finish milling by the milling machine, chamfering process, rounding process, surface polishing and stress treatment, production requirements are satisfied, precision and intensity of the produced connecting rod are improved to meet with requirements, defective rate is reduced, and production cost is lowered.
