The invention discloses a fixture for machining a connecting rod hole, which comprises a baseboard, a guide shaft, a compressing device, a positioning block, a slide block, locking screws, a fixed board and adjusting screws; one end of the baseboard is fixedly connected with the guide shaft, and the other end of the baseboard is provided with the slide block; the slide block is further provided with guide slots and can slide in the guide slots; the slide block is further coaxially and fixedly connected with a positioning shaft; and one side of the slide block is limited by the fixed board and the adjusting screws, locking nuts are arranged on the locking screws, and the positioning block is arranged between the guide shaft and the slide block. Due to the adoption of the fixture for machining the connecting rod hole, the coaxiality of two holes can be well guaranteed only by aligning the center of a large-end hole with the positioning shaft on the slide block, so that the operation is simple, and the production efficiency of products is improved.
Description
technical field [0001] The invention relates to a jig, in particular to a jig used for processing the big end hole of a connecting rod. Background technique [0002] The function of the connecting rod is to transmit the force borne by the piston to the crankshaft, and convert the reciprocating motion of the piston into the rotational motion of the crankshaft. The connecting rod is composed of connecting rod body, connecting rod cover, connecting rod bolt and connecting rod bearing bush. Since the connecting rod is one of the main parts of the engine, it requires relatively high machining accuracy, and the connecting rod is an irregular part, which requires many processing procedures and needs to be processed on different machine tools. It is also troublesome to clamp the rod itself. It needs to be clamped in a specific fixture. When processing the big and small holes of the connecting rod, the accuracy of the coaxiality between the two holes also needs to be very high. High...
