The invention discloses a locating device for machining of a spherical end of an automobile gear shift oscillating bar. Jacking air cylinders are symmetrically arranged at the left end and the right end of the top of a base. Piston rods of all the jacking air cylinders are connected with ejector rods. A locating block is arranged between the two jacking air cylinders and provided with a locating mandrel. A compressing oil cylinder is arranged behind the locating block. A piston rod of the compressing oil cylinder stretches vertically upwards and stretches in a U-shaped gap in the rear end of a pressing bar. The piston rod of the compressing oil cylinder is hinged to the rear end of the pressing bar through a first pin. The pressing bar and the locating mandrel are located in the same vertical plane. Connecting blocks are symmetrically arranged on the left side and the right side of the rear portion of the pressing bar. The upper ends of the two connecting blocks are hinged to the rear portion of the pressing bar through the same second pin, and the lower ends of the connecting blocks are connected with a support on a cylinder body of the compressing oil cylinder. By means of cooperation of the ejector rods on the left side and the right side, the locating block, the locating mandrel and the pressing bar, the gear shift oscillating bar can be located accurately, clamping firmness is good, and clamping efficiency is high.
Description
technical field [0001] The invention relates to a positioning device for processing the ball end of an automobile shift rod, which is used for clamping the shift rod to process the ball end. Background technique [0002] The shift lever is an important part of the car gearbox. The existing shift lever is generally a steel forging, which is composed of a shaft sleeve, a ball head, a leg and a corrugated surface. There are pin holes, and the female and female pins are passed through the pin holes, so that the bushing and the shaft are fixed. The ball head of the gearshift lever is further processed on a lathe, and the gearshift lever must be positioned on the lathe with the aid of a specially made clamping device. The existing clamping device has a complex structure and a large volume, which is not only difficult to assemble, but also has high production costs, and the clamping operation is cumbersome, the clamping efficiency is not high, and the clamping reliability is not ...
