Description

Technical Field

[0001] This utility model relates to the field of tapered tube and flange assembly technology, and in particular to a tapered tube assembly tooling. Background Technology

[0002] The core purpose of tapered pipes is to achieve smooth connections between pipes of different diameters, optimize fluid / gas transport efficiency, and adapt to specific structural support requirements. They are widely used in industry, construction, transportation, and other fields. In the splicing of pipes of different diameters, we generally use flanged connections. Tapered pipe and flanged connections have two main advantages: 1) Easy installation: When splicing pipes of different diameters, simply align the two flanges and tighten them with bolts; 2) High reliability: The connection between tapered pipes and flanges is highly reliable, able to withstand high temperatures and pressures, and can operate in various harsh environments. Currently, flange and tapered pipe splicing is mainly done manually, which is inefficient and has poor performance. In view of the above, it is necessary to improve the existing flange and tapered pipe assembly method so that it can meet the current needs of flange and tapered pipe assembly. Utility Model Content

[0003] The purpose of this invention is to solve the above problems by designing a tapered tube assembly tool.

[0004] The technical solution of this utility model to achieve the above objectives is a tapered tube assembly tooling, including a base plate, a supporting steel plate disposed on the base plate, a plurality of first positioning pins arranged in a circumferential array on the base plate, a plurality of positioning columns arranged in a circumferential array on the base plate, and a second positioning pin disposed on the positioning columns. The center of the base plate and the supporting steel plate are coaxial, the center of the circumferential array of first positioning pins and positioning columns is coaxial, the first positioning pins and positioning columns are fixedly installed on the base plate, and the center of the second positioning pins and positioning columns is coaxial.

[0005] As a further supplement to this technical solution, the first positioning pin is located at the mounting hole position of the tapered tube small flange, and the diameter of the first positioning pin is smaller than the diameter of the mounting hole of the tapered tube small flange.

[0006] As a further supplement to this technical solution, the second locating pin is located at the mounting hole position of the tapered pipe large flange, and the diameter of the second locating pin is smaller than the diameter of the mounting hole of the tapered pipe large flange.

[0007] As a further supplement to this technical solution, the outer diameter of the supporting steel plate is half the sum of the outer diameter and inner diameter of the small end of the tapered tube.

[0008] As a further supplement to this technical solution, the thickness of the supporting steel plate is the distance between the plane of the small flange of the tapered tube and the plane of the tapered tube.

[0009] As a further supplement to this technical solution, the length of the positioning post is set according to the overall height of the tapered tube, and the diameter of the positioning post is greater than the diameter of the mounting hole of the large flange of the tapered tube.

[0010] Its beneficial effects are: 1) It is easy to assemble and improves production efficiency. The small flange, tapered pipe and large flange are assembled in sequence, which is simple and convenient and has high assembly efficiency. 2) Positioning and assembly improve product quality; the coaxiality of the center of the multiple first and second positioning pin arrays in the circumferential array can ensure the coaxiality of the large and small flanges and the relative position of the holes; the size of the second positioning pin can ensure the overall height of the tapered tube. By assembling the first and second positioning pins, the coaxiality between all dimensions of the tapered tube and the flange can be guaranteed. Attached Figure Description

[0012] To facilitate a clearer understanding of this technical solution for those skilled in the art, the following will be described in conjunction with the appendix. Figure 1-2 Detailed explanation of the specific structure and principle of this technical solution: First, it should be noted that this technical solution applies to the assembly of a tapered pipe and a flange. Since the two ends of the tapered pipe have different diameters, this technical solution refers to the smaller diameter end as the small end of the tapered pipe and the larger diameter end as the large end. Therefore, in this technical solution, the small flange refers to the end with the smaller diameter of the tapered pipe, and the large flange refers to the end with the larger diameter of the tapered pipe. The mounting holes on the small flange refer to the multiple mounting holes arranged in a circumferential array on the small flange, and the mounting holes on the large flange refer to the multiple mounting holes arranged in a circumferential array on the large flange. This technical solution will be described in detail below: A tapered tube assembly fixture includes a base plate 1, a supporting steel plate 2 mounted on the base plate 1, a plurality of first positioning pins 3 arranged in a circumferential array on the base plate 1, a plurality of positioning posts 4 arranged in a circumferential array on the base plate 1, and a second positioning pin 5 mounted on the positioning posts 4. The base plate 1 and the supporting steel plate 2 are coaxial in center. The first positioning pins 3 and the positioning posts 4 are coaxial in center. The first positioning pins 3 and the positioning posts 4 are fixedly installed on the base plate 1. The second positioning pins 5 and the positioning posts 4 are coaxial in center. The base plate 1 is the assembly plane, the supporting steel plate 2 is mounted on the base plate 1, and the centers of the base plate 1 and the supporting steel plate 2 are coaxial with the centers of the first positioning pins 3 and the positioning posts 4 arranged in a circumferential array.

[0013] The first positioning pin 3 is located at the position of the tapered tube small flange mounting hole 7, and the diameter of the first positioning pin 3 is smaller than the diameter of the tapered tube small flange mounting hole 7. The first positioning pin 3 can position the tapered tube small flange 6, which facilitates the subsequent installation of the tapered tube 10.

[0014] The second positioning pin 5 is located at the mounting hole 9 of the tapered pipe large flange, and the diameter of the second positioning pin 5 is smaller than the diameter of the mounting hole 9 of the tapered pipe large flange. The second positioning pin 5 can position the tapered pipe large flange 8, which facilitates the connection between the tapered pipe 10 and the large flange, controls the flange assembly position, and improves production quality.

[0015] The outer diameter of the supporting steel plate 2 is half the sum of the outer diameter and inner diameter of the small end of the tapered tube 10. The supporting steel plate 2 is the supporting surface of the tapered tube 10. The thickness of the supporting steel plate 2 is the distance between the plane of the small flange 6 of the tapered tube and the plane of the tapered tube 10.

[0016] The length of the positioning post 4 is set according to the overall height of the tapered tube 10. The diameter of the positioning post 4 is larger than the diameter of the large flange mounting hole 9 of the tapered tube. The second positioning pin 5 is used to position the large flange mounting hole. The positioning post 4 can support the large flange.

[0017] The overall working principle of this utility model will be explained in the following system: First, the small flange is positioned and assembled by the first positioning pin 3. Then, the tapered tube 10 is assembled on the support plate. The gap between the tapered tube 10 and the small flange is uniform. Then, the large flange is positioned by the second positioning pin 5 to complete the assembly of the large flange. The whole process ensures the coaxiality of the large flange and the small flange and the relative position of the holes. Compared with the traditional assembly method, it greatly improves production efficiency and product quality.

[0018] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
