Abstract

The utility model provides a tool clamp with an inclination angle for a valve seat ring, which comprises a base, a backing plate and a working plate, wherein the base, the backing plate and the working plate are sequentially stacked and installed from bottom to top, the upper surface of the backing plate is an inclined plane, a cross-shaped track is arranged along the upper end of the working plate, a notch is arranged at the center of the working plate along the track, sliding blocks are arranged at four ends of the track in a sliding manner, a clamping seat is arranged on each sliding block, a mandril penetrates through the clamping seat along the surface of a step, and a clamping head is sleeved at one end, close to the notch, of the mandril; according to the utility model, the base plate is arranged to enable the working plate to have a certain angle, after the base plate is fixed with the lathe, the working plate generates a corresponding angle with a lathe processing plane, so that an end face angle can be directly processed on the valve seat ring, and the valve seat ring is clamped by the clamping seat from four angles through the arrangement of the rail, so that the processing efficiency is improved and low.

Description

Clamping tool with inclination angle for valve seat ring

Technical Field

The utility model mainly relates to the field of ball valve machining, in particular to a tool clamp with an inclination angle for a valve seat ring.

Background

The valve seat circle is critical part in the valve body sealing member, and to the valve seat circle that has inclination, need divide into two processes and accomplish at present, and to the valve seat circle of different size, still need change equipment, machining efficiency is low.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model provides a tool clamp with an inclination angle for a valve seat ring, which comprises a base 1, a backing plate 2 and a working plate 3 which are sequentially stacked from bottom to top, wherein the upper surface of the backing plate 2 is an inclined plane,

the working plate 3 has been seted up along the upper end and has been the track 4 of cross form, opening 5 has been seted up along track 4 center department to working plate 3, four equal slidable mounting in tracks 4 have slider 6, be equipped with holder 7 on slider 6, holder 7 wears to be equipped with ejector pin 8 along the step face, the pot head that ejector pin 8 is close to opening 5 is equipped with chuck 9.

Preferably, the collet 9 is made of a rubber material.

Preferably, the ejector rod 8 penetrates through the step surface of the clamp seat 7 in a threaded rotating mode.

Preferably, a baffle 10 for limiting the moving distance of the sliding block 6 is inserted at one end of the track 4 far away from the notch 5.

Preferably, the cross section of the track 4 is of an inverted T-shaped structure.

Preferably, the four corners of the working plate 3 are all inserted with positioning pins 11 for fixedly connecting with the backing plate 2.

Preferably, the inclined plane of the backing plate 2 forms an included angle x with the side wall, and the included angle x is more than 0 degree and less than or equal to 80 degrees.

The utility model has the beneficial effects that:

make the working plate have certain angle through setting up the backing plate, with bottom plate and fixed back of lathe, the working plate produces the angle that corresponds with lathe work plane promptly, can directly circle at the disk seat and process out the terminal surface angle, makes the holder follow four angles centre gripping disk seat circles through setting up the track, and it is low to improve machining efficiency.

Detailed Description

In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the utility model only and are not intended to limit the scope of the utility model.

As shown in fig. 1, the present invention includes: a base 1, a backing plate 2 and a working plate 3 which are sequentially stacked from bottom to top, wherein the upper surface of the backing plate 2 is an inclined plane,

In the present embodiment, the collet 9 is preferably made of a rubber material.

In this embodiment, the push rod 8 is preferably threaded through the step surface of the holder 7.

In this embodiment, a stop 10 for limiting the displacement distance of the slide 6 is preferably inserted into the end of the rail 4 remote from the notch 5.

In this embodiment, the cross section of the rail 4 is preferably an inverted T-shaped structure.

In this embodiment, it is preferable that the four corners of the working plate 3 are inserted with positioning pins 11 for fixedly connecting with the backing plate 2.

In the present embodiment, the inclined plane of the backing plate 2 forms an included angle x with the side wall, and the included angle x is 0 degrees and less than or equal to 80 degrees.

In use, through setting up the backing plate messenger's working plate there is certain angle, with the fixed back of bottom plate and lathe, the working plate produces the angle that corresponds with lathe work plane promptly, can directly process out the terminal surface angle on the disk seat circles, makes the holder follow four angles centre gripping disk seat circles through setting up the track, improves machining efficiency low.

The above-described embodiments are merely illustrative of the principles and utilities of the present patent application and are not intended to limit the present patent application. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of this patent application. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical concepts disclosed in the present application shall be covered by the claims of this patent application.
