[0002] The automobile scroll compressor accessory includes: static scroll and valve piece. In the assembly process of the static scroll and the valve piece, the valve piece needs to be positioned using a positioning template. The current positioning template is a unitary piece. Because the top surface of the static scroll has two reference surfaces with different reference heights, the bottom surface of the positioning template is processed into a stepped surface. If the stepped surface has a processing error, the positioning template can only fit one of the reference surfaces and have a gap with the other reference surface, thereby causing positioning error and instability in the assembly process. SUMMARY

[0012] The utility model will be further described in detail through specific implementation manners and with reference to the drawings. It needs to be explained here that the description of the implementation manners is used to help understanding the utility model, but does not constitute the limitation to the utility model. In addition, the technical features involved in each implementation manner of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0013] Reference is made to Figs. 1 to 3, and a double-layer template positioning tool is shown in the figure. The double-layer template positioning tool is fixed on the top surface of the static scroll 100. The double-layer template positioning tool is used for the assembly of the static scroll 100 and the valve plate 200. The top surface of the static scroll 100 includes a valve plate part 101, a first reference part 102 around the valve plate part 101, and a second reference part 103 around the first reference part 102, etc. The first reference part 102 and the second reference part 103 have different reference heights. In a specific implementation, the reference height of the first reference part 102 is greater than the reference height of the second reference part 103. The bottom surface of the static scroll 100 is abutted against the base 5.

[0014] The double-layer template positioning tool includes a lower layer template 1, an upper layer template 2, a template guide column 3, and a positioning compression spring 4, etc.

[0015] The lower layer template 1 is above the static scroll 100. The bottom surface of the lower layer template 1 is abutted against the second reference part 103 on the top surface of the static scroll 100. The lower layer template 1 is supported by the second reference part 103 on the top surface of the static scroll 100. The lower layer template 1 has a lower layer hollow part for the valve plate part 101 and the first reference part 102 on the top surface of the static scroll 100. That is, the lower layer template 1 only covers the second reference part 103 on the top surface of the static scroll 100 and does not cover the valve plate part 101 and the first reference part 102 on the top surface of the static scroll 100, so that the valve plate part 101 and the first reference part 102 on the top surface of the static scroll 100 are exposed.

[0016] The upper layer template 2 is above the lower layer template 1. The bottom surface of the upper layer template 2 is abutted against the first reference part 102 on the top surface of the static scroll 100 through the lower layer hollow part. The upper layer template 2 is supported by the first reference part 102 on the top surface of the static scroll 100. The upper layer template 2 has an upper layer hollow part for the valve plate part 101 on the top surface of the static scroll 100. That is, the upper layer template 2 only covers the first reference part 102 on the top surface of the static scroll 100 and does not cover the valve plate part 101 on the top surface of the static scroll 100, so that the valve plate part 101 on the top surface of the static scroll 100 is exposed. The upper layer hollow part is a profiling hole, which has a common shape and size with the valve plate 200.

[0017] The template guide column 3 is fixed on the top surface of the lower layer template 1. The upper layer template 2 has a template guide hole matched with the template guide column 3. The upper layer template 2 can be displaced up and down along the template guide column 3. Since the template guide column 3 and the template guide hole are matched with each other, the template guide column 3 limits the upper layer template 2 horizontally, and the upper layer template 2 cannot be displaced relative to the lower layer template 1 in the horizontal direction.

[0018] The positioning compression spring 4 is above the upper die plate 2. The upper end of the positioning compression spring 4 is a fixed end. The lower end of the positioning compression spring 4 is a movable end. The positioning compression spring 4 abuts against the upper die plate 2. The positioning compression spring 4 is in a compressed state. Through the positioning compression spring 4, the upper die plate 2 closely abuts against the first reference part 102 on the top surface of the static scroll 100.

[0019] When the valve plate 200 is placed on the valve plate part 101 on the top surface of the static scroll 100, the valve plate 200 is horizontally limited by the upper hollow part, so as to ensure the position requirement of the valve plate 200.

[0020] In specific implementation, the die plate guide column 3 penetrates upward through the die plate guide hole. The positioning compression spring 4 surrounds the die plate guide column 3. The die plate guide column 3 has a guide column shoulder part 31 above the positioning compression spring 4. The upper end of the positioning compression spring 4 abuts against the guide column shoulder part 31. Thus, the upper end of the positioning compression spring 4 is fixed.

[0021] In specific implementation, the number of the die plate guide column 3 is not less than four, which are respectively arranged at the corner positions of the upper die plate 2, so as to uniformly apply force to the upper die plate 2.

[0022] The above only expresses the implementation mode of the present application, and the description is relatively specific and detailed, but it cannot be understood as the limitation of the scope of the present application. It should be noted that, for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
