Description

Pneumatic Clamping Drill Press Fixtures

technical field

The utility model relates to the technical field of fixtures, in particular to a pneumatic clamping fixture for a drilling machine.

Background technique

The valve body as shown in accompanying drawings 1 and 2 needs to be installed on a vertical drilling machine. There is an inner hole 8 to be processed on the valve body. The drilling machine is used to drill the coaxial line of the valve body. Hole, M8mm threaded bottom hole and countersinking 2mm deep. workpiece with Outer mouth, The holes are respectively positioned on the positioning sleeve and the chamfering pin. However, there is no suitable clamp in the prior art, resulting in difficulty in positioning the valve body.

Utility model content

The utility model aims to solve the problems in the above-mentioned prior art, and provides a pneumatic clamping fixture for a drilling machine, which is convenient in positioning, simple in operation and automatic in clamping.

The technical solution adopted by the utility model to solve its technical problems: the pneumatic clamping drilling machine fixture includes a base, one end of the base is equipped with a fixed positioning seat, and the fixed positioning seat is provided with a positioning groove for positioning the outlet end of the valve body. A movable positioning seat is installed on the relative direction of the positioning seat. The movable positioning seat is installed on the piston rod of the cylinder, and the cylinder is connected with an air pump. The movable positioning seat includes a pressing plate fixed on the piston rod, a lifting seat installed on the base, and a lifting seat. A lifting support rod is slidably installed on the top, a column pin penetrating in the lifting seat is horizontally installed on the pressing plate, and a wedge-shaped block that promotes the lifting support rod lifting is installed on the outer end of the column pin.

In order to further improve, a transverse spring is installed between the pressing plate and the lifting seat. In this way, the pressing plate is automatically ejected from the lifting seat, and the operation is more convenient.

Further improvement, a longitudinal support spring is installed between the bottom end of the lifting support rod and the base.

The beneficial effects of the utility model are: the utility model has a reasonable structural design and convenient positioning. When the handle of the air distribution valve on the air pump is turned, the compressed air enters the film-type cylinder, and the piston rod pushes the pressure plate connected with the movable joint to clamp the workpiece. At the same time, the pressure plate pushes The column pin advances and is locked and supported by the wedge action. The hinged drilling template is designed for the convenience of loading and unloading workpieces.
