Pneumatic drilling equipment

Abstract

The invention discloses pneumatic drilling equipment comprising a machine table, wherein a positioning mechanism, a workpiece clamping mechanism and a drilling mechanism are arranged on the machine table; the drilling mechanism comprises a fixed support and a drill body; the drill body comprises an outer barrel, a linear pneumatic drill, and a cylinder; an oilless bush is arranged on the inner wall of the outer barrel, and an inner barrel capable of axially moving is arranged in the oilless bush; an end cover is arranged at the upper end of the inner barrel; the linear pneumatic drill is fixedly arranged in the inner barrel; a fixed cover is arranged at the piston outlet end of the cylinder body of the cylinder; the piston end of the cylinder is connected to the end cover, and the cylinder body of the cylinder is connected to one end of the outer barrel via the fixed cover; and the drill body is arranged above the positioning mechanism. According to the invention, a to-be-drilled piece is placed on the positioning mechanism, and after the to-be-drilled piece is automatically clamped by using the workpiece clamping mechanism, the cylinder pushes the inner barrel to drive the pneumatic drill to press downwards and drill along the oilless bush. The pneumatic drilling equipment is simple in operation, low in production cost, reliable in performance, practical, safe, and capable of reducing the labour intensity.

Description

technical field [0001] The invention relates to a drilling device, in particular to a pneumatic drilling device. Background technique [0002] At present, in order to prevent the corrosion of the automobile exhaust pipe, the water in the exhaust pipe is discharged in time by drilling holes in the tail section of the exhaust pipe to prolong the service life of the exhaust pipe. In the prior art, most of the drilling work at the tail section of the exhaust pipe is done manually, which is not only labor-intensive, time-consuming and labor-intensive, but also has high production costs, and the depth of drilling is difficult to control manually, which makes the product quality The yield rate is low. In addition, the manual punching method is easy to cause injury to the operator, and there is a great potential safety hazard. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to propose a pneumatic drillin...
