Abstract

The invention discloses a deep hole polishing machining device which comprises a disc-shaped tool body. An installation hole matched with a boring tool rod is arranged at the center of the tool body. Multiple installation grooves are evenly distributed in the outer surface of the tool body in the circumferential direction. Each installation groove is internally provided with a polishing assembly. Each polishing assembly comprises a polishing block, wherein the shape of the side edge of the polishing block is consistent with the shape of the side edge of the corresponding installation groove, and the side edge of the polishing block and the side edge of the corresponding installation groove are in sliding contact. The outer surface of each polishing block is provided with an arc face consistent with the hole face of a to-be-machined deep hole. Each polishing block is connected with the tool body through two connecting screws which are arranged in the radial direction of the tool body. Each connecting screw is sleeved with an elastic supporting piece. The two ends of each elastic supporting piece are pressed on the bottom of the corresponding installation groove and the inner surface of the corresponding polishing block correspondingly. By the adoption of the deep hole polishing machining device, floating type polishing can be conducted on the machined deep hole, and therefore the surface smoothness of the deep hole can be obviously improved, and the form and location tolerance of the deep hole can be corrected.

Description

technical field [0001] The invention belongs to the technical field of deep hole surface processing, in particular to a deep hole grinding device. Background technique [0002] When machining a hole on a workpiece, when the depth of the hole is more than 10 times the diameter of the hole, it is usually called a deep hole. The deeper the hole, the more difficult it is to process. At present, the processing of deep holes is usually realized on deep hole drilling and boring equipment. Generally, the surface finish of deep holes can reach 3.2. Affected by factors such as many process systems, it is difficult for existing processing equipment to meet the requirements. Contents of the invention [0003] In order to solve the technical problems in the known technology, the present invention provides a deep hole grinding processing device with simple structure and convenient operation, which can obviously improve the surface smoothness of the deep hole and correct the shape and p...
