Grinding device for crankshaft remanufacturing

Abstract

The invention relates to a grinding device for crankshaft remanufacturing. The grinding device comprises a clamping assembly used for clamping the two ends of a crankshaft and driving the crankshaft to rotate, wherein the distance between the two ends of the clamping assembly can be adjusted; and the clamping assembly is provided with a plurality of grinding assemblies used for grinding shaft necks at different positions of the crankshaft at the same time. According to the grinding device, a plurality of sets of arch-shaped rods and grinding belts are arranged on a ratchet wheel rod, the arch-shaped rods drive the grinding belts to transversely move along the ratchet wheel rod, and one-to-one correspondence with the shaft necks of the crankshaft below is achieved; meanwhile, the arch-shaped rods and pawls for locking rotation of the arch-shaped rods are rotated, and the grinding belts can make contact with the shaft necks of the crankshaft; each set of grinding belts correspond to oneshaft neck of the crankshaft, the grinding belts are driven to rotate through transmission of a power rod, a first gear, a second gear and a transmission belt wheel, and multi-set synchronous rotationgrinding is achieved; and the multiple grinding belts conduct grinding at the same time, the grinding speed is increased, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical production and reprocessing, in particular to a grinding device for crankshaft remanufacturing. Background technique [0002] The crankshaft is the main rotating part of the engine. After the connecting rod is installed, the up and down (reciprocating) motion of the connecting rod can be changed into a circular (rotating) motion. It mainly includes the main journal, the connecting rod journal, and the main journal is installed on the cylinder block. The connecting rod neck is connected with the large end hole of the connecting rod, and the small end hole of the connecting rod is connected with the cylinder piston, which is used to bear the force transmitted from the connecting rod, convert it into torque and output it through the crankshaft and drive other accessories on the engine to work. Remanufacturing is the process of rejuvenating old machinery and equipment. It uses old machinery and equipment as ...

Problems solved by technology

However, the main journal and the connecting rod journal are not arranged on the same axis, so the traditional grinding device has to adopt the method of grinding one by one. This method is slow and seriously affects the efficiency of work.
