Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, a top view of the valve plate 16 shows, the valve plate 16 is provided with a plurality of processing holes 17, and the processing holes 17 include an outer valve hole 18, a center hole 19 and an inner valve hole 20. The machining holes 17 are all formed in a fine punching mode.

The valve plate checking fixture shown in fig. 2 and 3 is used for detecting the position degree of the machined hole 17 and finding a hole which is not machined.

The valve plate detection tool comprises a bottom plate 1, a base plate 2 and a detection pin 3. The base plate 1 and the backing plate 2 are detachably connected together by bolts I12. The detection pin 3 is detachably fixed with the pad 2.

As shown in fig. 4, a through hole 4 is formed in the backing plate 2, a groove 7 is formed at the bottom of the through hole 4, and the size of the groove 7 is slightly larger than that of the through hole 4. As shown in fig. 3, the detection pin 3 (the outer valve hole detection pin 9, the center hole detection pin 10, or the inner valve hole detection pin 11) includes a detection portion 5 and a fixing portion 6 which are integrally provided. The detecting part 5 is arranged in the penetrating hole 4 (see fig. 4) in a penetrating way, the fixing part 6 is arranged in the groove 7 (see fig. 4), the size of the fixing part 6 is slightly larger than that of the detecting part 5, or the size of the fixing part 6 is slightly larger than that of the penetrating hole 4, so that the fixing part 6 cannot enter the penetrating hole 4. When backing plate 2 and bottom plate 1 combine together, backing plate 2 and bottom plate 1 surface in opposite directions paste closely so that comparatively steadily do not rock between the two, will detect round pin 3 and fix in backing plate 2.

As shown in fig. 3, the detecting portion 5 of the detecting pin 3 is exposed on the upper surface of the backing plate 2 for insertion into the machining hole 17 of the valve plate 16 (see fig. 1) for comparison inspection.

As shown in fig. 3, the top edge of the outer valve wire hole detection pin 9 in the detection pin 3 is provided with a chamfer which is an R2.5 chamfer; the tops of a central hole inspection pin 10 and an inner valve line hole inspection pin 11 in the inspection pin 3 are provided with ball heads. The chamfer and bulb are for ease of insertion of the valve plate 16 (see FIG. 1).

The detection pin 3 is detachable, so that the detection pin 3 can be conveniently installed, and the damaged detection pin 3 can be conveniently replaced.

In other embodiments, instead of providing the groove 7, it is also possible to place the shim plate 2 and the base plate 1 at a distance from each other, which distance serves to accommodate the fixing portion 6. This is another way in which the fixing portion 6 is clamped between the underlay sheet 2 and the base sheet 1.

Referring to fig. 3 and 4, a plurality of cushion blocks 8 are further connected to the bottom of the bottom plate 1, and the cushion blocks 8 are detachably combined with the bottom plate 1 through bolts ii 13. The main function of the spacer 8 is to facilitate the adjustment of the height of the base plate 1 and the correction of horizontal skew, which is usually achieved by replacing spacers 8 of different heights. The number of the spacers 8 is not limited. The specific location of the spacer 8 is also not limited, for example, the spacer 8 may be attached to the side of the base plate 1.

As shown in fig. 2 and 3, the detection pins 3 are disposed in one-to-one correspondence with the machining holes 17 in the valve plate 16 (see fig. 1). The outer peripheral shape of the detection pin 3 is matched with the processing hole 17, and specifically, the outer peripheral shape of the detection part 5 on the detection pin 3 is matched with the processing hole 17. The sensing pin 3 includes an outer valve wire hole sensing pin 9, a center hole sensing pin 10, and an inner valve wire hole sensing pin 11, which correspond to an outer valve wire hole 18, a center hole 19, and an inner valve wire hole 20 in the valve plate 16, respectively (see fig. 1). And (3) putting the machining hole 17 of the valve plate 16 into the corresponding detection pin 3, wherein if the machining hole 17 corresponding to the valve plate 16 can smoothly and completely enter, the hole position degree is qualified, no machining hole is missed, and otherwise, the hole position degree is unqualified.

In order to better compare the edge of the valve plate 16 and prevent the machining hole 17 from being shifted as a whole, the edge of the shim plate 2 is disposed to correspond to the edge of the valve plate 16.

The utility model discloses an utensil is examined to the valve plate can carry out the inspection of valve plate processing hole site degree and leak protection processing hole, has improved detection efficiency, is applicable to batch production, easy operation.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
