A casing automatic chamfering grinding machine

Abstract

The invention discloses an automatic chamfering and grinding machine for sleeves. The automatic chamfering and grinding machine comprises a machine base, a feeding device, two first chamfering devices, two second chamfering devices, two grinding devices and a walking device, wherein the feeding device is arranged at the end part of the machine base, the two first chamfering devices are arranged on the machine base and chamfer the two ends of inner lining pipe bodies of the sleeves at the same time, the two second chamfering devices are arranged on the machine base and chamfer the two ends of outer pipe bodies of the sleeves at the same time, the two grinding devices are arranged on the machine base and grind the two ends of the outer pipe bodies of the sleeves at the same time, and the walking device is arranged on the machine base and is used for clamping the sleeves and moving the sleeves to machining stations; the two first chamfering devices, the two second chamfering devices and the two grinding devices are symmetrically arranged on the two sides of the walking device separately; first sliding rails, second sliding rails and third sliding rails are arranged on the machine base; and the first chamfering devices, the second chamfering devices and the grinding devices are arranged on the first sliding rails, the second sliding rails and the third sliding rails through sliding blocks respectively. The automatic chamfering and grinding machine has the advantages that the chamfering speed for the sleeves is high, continuous work for a long time can be realized, the chamfering quality is high, and the efficiency is high.

Description

technical field [0001] The invention belongs to the field of casing chamfering processing, and in particular relates to an automatic casing chamfering grinder. Background technique [0002] In order to increase the wear resistance and corrosion resistance of the casing, an inner liner is usually provided in the casing. At present, for workpieces, especially casing workpieces with inner liners, manual chamfering and grinding are generally used. However, manual operation has some shortcomings. On the one hand, there are many human factors, and the quality of workpiece chamfering and grinding is uneven. On the other hand, the chamfering and grinding speed is slow, the efficiency is low, the precision is poor, and the finished product is not very high. In addition, although manual grinding can be carried out in multiple bundles, the chamfering needs to be performed one by one, and the two ends of the workpiece cannot be chamfered at the same time, and it cannot work continuously...

Problems solved by technology

However, manual operation has some shortcomings. On the one hand, there are many human factors, and the quality of workpiece chamfering and grinding is uneven. On the other hand, the chamfering and grinding speed is slow, the efficiency is low, the precision is poor, and the finished product is not very high.

In addition, although manual grinding can be bundled together, the chamfering needs to be performed one by one. It is impossible to chamfer both ends of the workpiece at the same time, and it cannot work continuously for a long time.
