Rapid drilling device for air compressor production

Abstract

The invention discloses a rapid drilling device for air compressor production, and belongs to the technical field of machine tool drilling equipment. A pair of dovetail sliding rails and a rail groove are arranged on the machine tool workbench, and a two-way screw rod is installed in the rail groove in a rotating mode. A left sliding plate and a right sliding plate are mounted on the dovetail sliding rail; the lower sides of the left sliding plate and the right sliding plate are in threaded connection with a bidirectional screw rod; a positioning tool is mounted on the right sliding plate; a vertical plate is fixed on the left sliding plate; a cantilever plate is fixed at the upper end of the vertical plate; a drill plate is embedded in the cantilever plate through hole; one side, close to the right sliding plate, of the left sliding plate is provided with a pair of extension arms; a positioning plate is embedded between the extension arm positioning grooves; the right sliding plate is located between the two extension arms and opposite to the positioning plate, and a sinking groove matched with the right sliding plate is formed in the side, close to the right sliding plate, of the positioning plate. A workpiece can be selected to be opposite to any drill plate, two drilling layouts of the workpiece are achieved, the workpiece drilling efficiency is improved, the workpiece is prevented from being transferred between different machine tools, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of machine tool drilling equipment, in particular to a quick drilling device for air compressor production. Background technique [0002] At present, in the field of public transportation, the share of new energy vehicles is getting higher and higher. There are many pneumatic components inside new energy vehicles, so air compressors are needed to provide air sources. The current air compressors mainly include motors, boxes, cylinders, and missing covers. and crankcase and other components. During the production process, parts such as the box body and the cylinder need to drill corresponding threaded holes or positioning holes to realize the subsequent assembly of complete products. [0003] The Chinese patent discloses a fixing fixture (CN204657999U) for drilling the crankcase of an air compressor, which includes a base and a pressing plate. The pressure plate can move up and down along the guide column un...

Problems solved by technology

[0004]The problem with the above technology is: when the workpiece is installed, the pressure plate needs to be raised, although the pressure plate has a certain height at this time, it will still affect the installation of the workpiece; Used as a positioning part and a drill guide at the same time, although it can reduce tooling, it will make it difficult to replace the drill guide. For workpieces that require double-sided or multi-type drilling, it must be processed in two processes, and the workpiece The transshipment will result in the reduction of processing efficiency and processing accuracy
