Description

A pneumatic chuck device

technical field

The utility model relates to a pneumatic chuck, which is particularly suitable for high-precision machining on a machining center that needs to be positioned by an outer circle or an inner hole.

Background technique

Chucks are generally used on lathes to process the outer circle and inner hole of shaft parts. When the three-jaw clamping parts are installed on the chuck, the requirements for the outer circle or inner hole size of the clamping place are not high; the machining center milling, drilling When the tooling used is positioned by the inner hole or the outer circle, the tolerance of the inner hole and the outer circle needs to be controlled, and the size is stable so that it can be used for positioning and control the related position dimensions. Common chucks cannot meet the size requirements.

Contents of the invention

In order to solve the above problems, the utility model provides a pneumatic chuck device, which has a simple structure, can conveniently realize effective positioning, is easy to operate, and improves the dimensional qualified rate.

Its technical scheme is as follows: a kind of pneumatic chuck device, it is characterized in that, it comprises base plate, and cylinder is installed vertically on described base plate, and chuck is installed on the piston rod of described air cylinder through pulling cap, and described base plate A support column is also installed on the support column, and a horizontally arranged connection base is fixedly installed on the support column. A through hole is opened on the connection base. The piston rod of the cylinder passes through the through hole, and the piston rod of the cylinder When retracted, the chuck is supported on the connecting base.

It is further characterized in that an annular boss is installed on the connecting base;

Three support columns are evenly arranged on the bottom plate;

The size of the through hole is larger than the size of the pull cap.

After adopting the structure of the utility model, the chuck is connected to the cylinder by pulling the cap, and the change of the position of the chuck can be realized by controlling the expansion and contraction of the piston rod of the cylinder, so as to adapt to the size of the workpiece, and the effective positioning can be realized through simple structural settings , to ensure the size pass rate, and easy to operate.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

As shown in Figure 1, a pneumatic chuck device includes a base plate 1, a cylinder 2 is vertically installed on the base plate 1, a chuck 4 is installed on the piston rod of the cylinder 2 through a pull cap 3, and three cylinders are installed on the base plate 1. A support column 5 evenly arranged, the support column 5 is fixedly installed with the connection base 6 arranged horizontally, to ensure the support of the connection base 6 is stable, there is a through hole 7 in the middle of the connection base 6, and the size of the through hole 7 is larger than the size of the pull cap 3 , so that the pull cap 3 can pass through the through hole to further realize the up and down movement of the chuck 4, the piston rod of the cylinder 2 passes through the through hole 7, and the chuck 4 is supported on the connecting base 6 when the piston rod of the cylinder 2 is retracted. The connection base 6 plays the role of supporting the chuck 4. When the chuck 4 is not in operation, the piston rod of the cylinder 2 retracts, the connection base 6 supports the chuck 4, reduces the pressure of the cylinder 2, protects the cylinder 2, and connects the base 6 An annular boss 8 is installed to further support the chuck 4, and at the same time, it can play the role of guiding the limit chuck 4; the required three claws can be installed on the chuck 4 according to the processing needs, and the processing operation can be realized through the three claws .
