Vertical and horizontal dual-purpose special angle head suitable for special machining

Abstract

The invention discloses a vertical and horizontal dual-purpose special angle head suitable for special machining. The vertical and horizontal dual-purpose special angle head suitable for special machining comprises a box, a main shaft and a transmission mechanism which is installed between the box and the main shaft. The vertical and horizontal dual-purpose special angle head suitable for special machining is characterized in that the box is composed of an upper box and a lower box, and a plurality of needle bearings are installed between the upper box and the transmission mechanism; a front main-shaft bearing pedestal is fixedly installed on the lower box, the front end of the main shaft is fixed on the front main-shaft bearing pedestal through a first back-to-back angular contact ball bearing, and the rear end of the main shaft is fixed on the lower box through a second back-to-back angular contact ball bearing; the included angle ranging from 30 degrees to 45 degrees is formed between the main shaft and the transmission shaft. The vertical and horizontal dual-purpose special angle head suitable for special machining has the advantages of being good in rigidity, large in torque, small in size, beautiful, capable of achieving high machining accuracy under the vertical and horizontal dual-purpose conditions, suitable for rough machining and semi-finish machining of deep cavities, capable of achieving finish machining, capable of being applied to special machining of gantry machine tools and floor type boring machine tools, and particularly suitable for machining bumper bars of automobiles.

Description

technical field [0001] The invention relates to an automatic head, in particular to a vertical and horizontal dual-purpose special-angle head suitable for special processing. Background technique [0002] Difficulties in the existing die processing of automobile bumpers are: deep cavity, small tool, and often use 3+2 spindle heads to process, but the rigidity of 3+2 spindle heads is not enough, so it can only be used for final finishing, so The semi-finishing of the mold is still more troublesome. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a vertical and horizontal dual-purpose special angle head suitable for special processing in view of the deficiencies of the prior art. [0004] The technical solution adopted by the present invention to solve the above technical problems is: a vertical and horizontal dual-purpose special angle head suitable for special processing, including a box body, a main shaft, a tr...
