Description

Technical Field

[0001] The utility model relates to the technical field of pipe intersecting line cutting tooling, in particular to a pipe intersecting line processing fixture. Background Art

[0002] The shape of mechanical parts is often formed by combining two or more basic solids in different ways. When combined, the two solids will intersect. The intersection of two solids is called the intersection of two solids. The intersection line formed on their surfaces is called the intersection line, which belongs to the category of descriptive geometry research and is often used in engineering construction. The intersection line is the common line of the two solid surfaces and the dividing line of the two solids; the points on the intersection line are the common points of the two solid surfaces.

[0003] Intersecting line cutting is a processing method that cuts along the intersecting lines of three-dimensional objects. Currently, the more common intersecting line cutting is the intersecting line cutting of pipe components.

[0004] At present, there are generally four methods for processing the intersection line of the pipe: the first is to use a CNC intersection line cutting machine, but after the thick-walled pipe is cut, the cross section needs to be ground again, so this processing method is only suitable for processing thin-walled pipes. The second is the wire cutting processing method, which has the advantage of processing relatively complex graphic structures with high precision, but the feed speed of the electrode wire is restricted by the parameters of the wire cutting machine, and there is not much room to increase the feed cutting speed, and only one product can be processed at a time, so its processing efficiency is low, resulting in high production costs. The third is the CNC machining center milling forming method. Although this method takes into account the advantages of the above two processing methods, it is limited by the processing capacity of the machinery factory and can only be applied to specific processing manufacturers. The fourth is the lathe turning processing method, which can turn the outer circle, inner circle, and the end face of the shaft and pipe, and can also turn the plane. It has strong adaptability and high production efficiency, but it needs to cooperate with special tooling fixtures, has a complex structure, low clamping efficiency, and is not convenient to adjust the radial size of the arc-shaped intersection line of the pipe end face. Utility Model Content

[0005] In order to solve the technical problems of low clamping efficiency and inconvenience in adjusting the radial dimension of the arc-shaped intersection line of the pipe end face of the existing intersection line cutting fixture, the utility model provides a pipe intersection line processing fixture.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A pipe intersection line processing fixture includes a positioning disk, a fixing plate is installed on the positioning disk, the fixing plate can slide and lock along a radial direction of the positioning disk, the fixing plate is connected to a sleeve on the side away from the positioning disk, the axial direction of the sleeve is set along the sliding direction of the fixing plate, and the end of the sleeve close to the center of the positioning disk is open.

[0008] By adopting the above-mentioned structural scheme, the positioning disk is installed on the turning machine tool, and the connecting pipe is placed in the sleeve so that the end of the connecting pipe close to the center of the positioning disk extends out of the sleeve, and the relative position of the connecting pipe and the sleeve is fixed. Then, the position of the fixed plate is slid according to the radius of the arc to be processed on the end face of the connecting pipe. The fixed plate drives the sleeve and the connecting pipe to move, and then the position of the fixed plate on the positioning disk is locked, thereby completing the clamping of the connecting pipe. Then, the main power supply of the turning machine tool is turned on, and the spindle of the machine tool drives the positioning disk to rotate and move forward, cutting the end face of the connecting pipe close to the center of the positioning disk, and processing the required arc-shaped intersection line. The present application has a simple structure, is convenient for clamping the connecting pipe, and is also convenient for adjusting the radial position of the sleeve on the positioning disk, thereby changing the radial size of the arc on the end face of the connecting pipe.

[0011] As a preferred implementation of a pipe intersection line processing fixture, a plurality of first bolt holes are provided.

[0012] The above structural solution can enhance the locking effect of the positioning plate and the fixing plate.

[0013] As a preferred implementation of a pipe intersection line processing fixture, a second bolt hole penetrating through the side wall of the sleeve is opened on the side wall of the sleeve, and the second bolt passes through the second bolt hole from the outside of the sleeve.

[0014] By adopting the above structural solution, the second bolt is tightened so that one end of the second bolt that penetrates into the sleeve abuts against the outer wall of the connecting pipe, thereby locking the connecting pipe and the sleeve.

[0015] As a preferred implementation of a pipe intersection line processing fixture, the second bolt hole is located at the top of the sleeve.

[0016] By adopting the above structural solution, the position of the connecting pipe in the sleeve can be fixed more reliably.

[0017] As a preferred implementation of a pipe intersection line processing fixture, a plurality of second bolt holes are provided.

[0020] By adopting the above structural solution, the limiting pin can limit the position of the connecting pipe, so that the connecting pipe can be put into place in one step, thereby improving the clamping tightness of the connecting pipe in the sleeve and saving clamping time.

[0021] As a preferred implementation of a pipe intersection line processing fixture, a through hole is opened at the center of the positioning plate, and the through hole penetrates the positioning plate in the thickness direction.

[0022] By adopting the above structural solution, the through hole can make way for the tool on the turning machine tool.

[0024] By adopting the above structural solution, multiple connecting pipes can be processed at one time, thereby improving the processing efficiency.

[0025] As a preferred implementation of a pipe intersection line processing fixture, the number of fixing plates is an even number, and every two fixing plates are located on the same diameter.

[0026] By adopting the above structural solution, the positioning plate is more balanced when rotating, thereby improving the processing quality.

[0036] Reference Figure 1-3The present embodiment proposes a pipe intersection line processing fixture, including a positioning plate 1, the positioning plate 1 is installed on a turning machine tool, a through hole 12 is opened in the center of the positioning plate 1, and the through hole 12 runs through the thickness direction of the positioning plate 1. A plurality of fixed plates 2 are slidably installed on the positioning plate 1, and the plurality of fixed plates 2 are arranged along the circumferential direction of the positioning plate 1. The number of fixed plates 2 is an even number, such as 2, 4, and 8, and every two fixed plates 2 are located on the same diameter of the positioning plate 1. The positioning plate 1 is provided with a plurality of sliding grooves 11 penetrating the thickness direction of the positioning plate 1.

The outer diameter of the bolt head of the first bolt 4 is greater than the width of the sliding groove 11. When the first bolt 4 is tightened, the positioning plate 1 and the fixing plate 2 can be locked. After the first bolt 4 is loosened, the fixing plate 2 can move in the length direction of the sliding groove 11. Therefore, each fixing plate 2 can slide and lock along a radial direction of the positioning plate 1. A sleeve 3 is welded on the side of each fixing plate 2 away from the positioning plate 1. The axial direction of the sleeve 3 is arranged along the sliding direction of the fixing plate 2. Both ends of the sleeve 3 are open.
