Honing machine

Abstract

The present invention relates to a honing machine belonging to a mechanical technique field, including a spindle drive, a reciprocation drive mechanism, a work bench, a honing head feed mechanism, a honing head, a digital control system, and a pneumatic on-line measurement system; the honing head includes a main shaft, a set of coarse honing emery sticks and a set of micro honing emery sticks locating on the main shaft, the honing head is provided with a two-stage telescoping hydraulic cylinder which includes a first cylinder rod and a second cylinder rod, when the first cylinder rod is protruded, the coarse honing emery sticks are protruded outward to implement coarse honing under the action of the first cylinder rod, when the second cylinder rod is protruded, the micro honing emery sticks are protruded to implement micro honing under the action of the second cylinder rod; the work bench is provided with a first oil cylinder, the honing head is capable of moving up and down under the action of a cylinder rod of the first oil cylinder. The structure of the honing machine is simple, the layout is reasonable, the operation stability and reliability are all good, the machining precision is high, cost is low, and it is capable of implementing the honing machining of parts with an inner pore diameter from 10mm to 150mm.

Description

technical field [0001] The invention relates to a honing machine. Background technique [0002] Honing is a process of finishing the finished surface with a honing stick embedded in the honing head. It mainly processes various cylindrical holes with a diameter of 5 to 500 mm or even larger. The ratio of the processed hole depth to the hole diameter up to 10 or more. Under certain conditions, honing equipment can also process flat surfaces, outer circular surfaces, spherical surfaces, tooth surfaces, etc. The dimensional accuracy of the hole after honing is IT4~7, and the surface roughness can reach Ra0.04~0.32 microns. In the honing process, for the honing process of some inner holes, it is necessary to use a coarse-grained honing stick to grind out the inner surface of the deep groove texture, and then use a fine-grained honing stick to grind off the peaks on the surface of the deep groove texture. , to achieve higher precision. This just needs to have the honing head o...

Problems solved by technology

This requires a honing head with a set of fine honing stones and a set of coarse honing stones, and two honing heads need two driving mechanisms to make the honing head stretch out for honing, which increases the structure of the equipment

And the prior art honing machine, when honing is required, the workpiece needs to be manually transported to the honing machine, and some workpieces are heavy, which is very inconvenient to help transport, resulting in a safety hazard
