Detailed Description

The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without inventive labor based on the embodiments of the present invention all belong to the protection scope of the present invention. In addition, all the connection relations mentioned herein do not mean that the components are directly connected, but mean that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The utility model discloses each technical feature in the creation can the interactive combination under the prerequisite that does not contradict conflict each other.

With reference to fig. 1 to 4, this is an embodiment of the invention, in particular:

the valve seat tool comprises a mounting seat 1 and a positioning column 2 fixedly arranged on the mounting seat 1, wherein a plurality of stop blocks 21 are arranged on the positioning column 2, the lower parts of the stop blocks 21 are fixedly connected with the positioning column 2, the upper parts of the stop blocks 21 are arranged above the positioning column 2, and the valve seat tool further comprises positioning protrusions 3 fixedly arranged on the mounting seat 1, and the positioning protrusions 3 are arranged at the side of the mounting seat 1.

The principle of the utility model is that: the valve seat main body 41 is clamped between the stop blocks 21 from top to bottom, the valve seat main body 41 is arranged above the positioning column 2, one air passage joint 42 of the valve seat 4 is sleeved on the positioning bulge 3, and the positioning bulge 3 and the stop blocks 21 jointly act to achieve the rotation stopping effect; the heights of the stop block 21, the positioning column 2 and the positioning bulge 3 are set according to the shape and the structure of the valve seat 4 so as to match the length of the air passage joint 42 of the valve seat 4 and limit the height of the valve seat 4; the spacing between the several stoppers 21 is set according to the size of the valve seat body 41 so that the stoppers 21 are interference-fitted or over-fitted with the valve seat body 41 to define the position of the valve seat 4 body. The utility model discloses a disk seat frock can 4 positions of fixed valve seat to can spline, disk seat main part 41 is favorable to quick installation and dismantlement with dog 21 joint, the mode that gas circuit joint 42 cup jointed with location arch 3.

Further, the number of the positioning protrusions 3 is two, and the two positioning protrusions 3 are arranged at intervals. Two protruding 3 of location are used for cup jointing with two different gas circuit connectors 42 on the disk seat, and two protruding 3 of location, reference column 2 form three places jointly and are connected between the disk seat, and gas circuit connector 42 on the disk seat is more usually, suitably sets up the distance between three connections, can surround the focus of disk seat between three tie point to avoid the disk seat to heel, be favorable to improving positioning accuracy. In addition, in the actual machining process, in order to machine different positions on the valve seat 4 at specific stations, the valve seat 4 generally needs to be rotated. Adopt the utility model discloses a structure comes the location, can follow this disk seat frock with disk seat 4 and take off, and rotatory certain angle carries out the clamping again, and rotatory back, gas circuit joint 42 with be different from the initial location protruding 3 of the location of cup jointing another location protruding 3 cup joint can. So, can guarantee the precision of the rotatory contained angle between two kinds of positions of disk seat 4 to this mode need not to increase specific rotation control mechanism, only needs manipulator or workman to take off disk seat 4 from this disk seat frock, rotatory after again with this disk seat frock be connected can. Because the position state of the valve seat 4 has a plurality of types, a plurality of positioning bulges 3 can be arranged to provide a plurality of clamping angles.

In some embodiments, the positioning protrusion 3 includes a lower step column and an upper step column fixed on the lower step column, the upper step column has a diameter smaller than that of the lower step column, and an upper end of the upper step column is provided with an oblique chamfer. Protruding 3 including lower step post and last step post in location, lower step post be used for with the bottom surface butt of gas circuit joint 42, go up the step post and be used for stretching into inside the gas circuit joint 42 and cup joint with gas circuit joint 42, the gas circuit joint 42 cup joints more smoothly with protruding 3 in location behind the chamfer.

In some embodiments, the stopper 21 is provided with a guiding inclined surface, and the guiding inclined surface is provided at an upper end of an inner side surface of the stopper 21. The surface of the stopper 21 facing the center axis of the positioning column 2 is the inner side surface of the stopper 21, and the upper end of the inner side surface of the stopper 21 is provided with a guide slope, which facilitates connection with the valve seat body 41.

In some embodiments, the cross section of the positioning column 2 is polygonal, and the lower portion of the stop 21 is bolted to the sidewall of the positioning column 2. The cross section of the positioning column 2 is polygonal, so that the side wall of the positioning column 2 is a plane, and the stop block 21 is conveniently fixed on the side wall of the positioning column 2.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
