Description

Technical Field

[0001] This utility model relates to a Y-type tee processing device for pipe connections, belonging to the field of pipe connection processing technology. Background Technology

[0002] During the manufacturing process of Y-type tees, annular grooves need to be machined on the three pipe ends. When the groove clamp is fastened onto the annular groove and the bolts are tightened, the inner edge of the clamp will be tightly inserted into the groove, forming a strong mechanical interlock. This connection method is called grooved connection.

[0003] Because of the irregular shape of the Y-type tee, which has a main pipe and an angled branch pipe, it is difficult to find a stable and reliable clamping point on a traditional lathe. Ordinary chucks or fixtures either cannot clamp effectively, or the workpiece is prone to loosening or jumping after clamping, resulting in clamping difficulties and instability. This leads to problems such as inaccurate groove dimensions and poor surface finish, failing to meet the requirements of high-precision sealing connections.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing a Y-type tee machining device that can achieve stable and reliable contour clamping, fundamentally eliminating workpiece jump and loosening, and ensuring extremely high machining accuracy.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: A Y-shaped tee processing device includes two clamping arms symmetrically arranged on the left and right, forming a clamping space between the two clamping arms that matches the shape of the Y-shaped tee. One end of each clamping arm is fixedly connected to a chuck. Connecting plates and clamping plates are provided at both ends of the clamping arms along the length direction. Multiple fastening holes are provided on the connecting plate of one of the clamping arms, and a first positioning element or a second positioning element is installed on the inner side of the connecting plate.

[0007] Furthermore, fastening holes are distributed on the upper and lower sides of the claw, and fasteners are inserted into the fastening holes to fix the first positioning member or the second positioning member to the inner side of the connecting plate.

[0008] Furthermore, the two jaws are located inside the lathe chuck.

[0009] Furthermore, the connecting plate and the clamping plate are located on the same side of the clamping arm, and the connecting plate is fixedly connected to the jaws.

[0010] Furthermore, a semi-circular clamping groove is provided on the side of the clamping plate away from the clamping arm.

[0011] Furthermore, a transverse ridge is provided on the upper inner side of the clamping arm, and an arc-shaped groove is provided on the transverse ridge.

[0012] Furthermore, the first positioning element is a block structure with a semi-circular groove on it.

[0013] Furthermore, the second positioning component consists of a straight plate and a right-angle plate, with the right-angle plate fixed to the side of the straight plate and the straight plate fixed to the inside of the connecting plate by fasteners.

[0014] Furthermore, it also includes cutting tools, which are mounted on a tool holder.

[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: The two clamping arms form a clamping space that matches the shape of the Y-shaped tee. The workpiece is clamped from multiple points simultaneously through the clamping groove and the arc groove. This annular clamping force stably transforms the irregular Y-shaped tee into a rotating body that can be safely rotated on the lathe, fundamentally eliminating runout and loosening. The tool can then accurately cut annular grooves with consistent size, regular shape, and smooth surface to meet the requirements of high-precision sealing connection. By replacing the first or second positioning component, the groove machining of the main pipe end and the branch pipe end can be completed respectively, which greatly reduces the number of clamping and alignment operations and significantly improves machining efficiency.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0019] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0020] like Figure 1 As shown, the Y-type tee 1 in the prior art includes a main pipe 11, and a branch pipe 12 connected to the main pipe 11 is provided on the main body of the main pipe 11. The center line of the branch pipe 12 is set at an angle to the center line of the main pipe 11. The pipe ends of the main pipe 11 and the branch pipe 12 are both machined with annular grooves 13.

[0021] like Figures 2-7 As shown in the figure, this utility model provides a Y-type tee processing device, including two clamping arms 2 arranged symmetrically on the left and right, forming a clamping space between the two clamping arms 2 that matches the shape of the Y-type tee 1, and one end of each of the two clamping arms 2 being fixedly connected to a chuck 3, with the two chucks 3 located inside the lathe chuck.

[0022] Power is transmitted sequentially from inside the lathe chuck to the jaws 3 and the clamping arms 2. When the two clamping arms 2 are closed, the Y-type tee 1 is clamped symmetrically and stably.

[0023] The clamping arm 2 has a connecting plate 21 and a clamping plate 23 at both ends along its length. The connecting plate 21 and the clamping plate 23 are located on the same side of the clamping arm 2, and the connecting plate 21 is fixedly connected to the claw 3. The clamping plate 23 has a semi-circular clamping groove 24 on the side away from the clamping arm 2, which is used to clamp the outer wall of the main pipe 11 or the branch pipe 12.

[0024] The clamping arm 2 has a transverse protrusion 25 on its inner upper side, and an arc groove 26 on the transverse protrusion 25. The arc groove 26 is used to grip the outer wall of the main pipe 11 or the branch pipe 12.

[0025] One of the clamping arms 2 has a plurality of fastening holes 22 on its connecting plate 21. The fastening holes 22 are distributed on the upper and lower sides of the claw 3. A first positioning member 4 or a second positioning member 5 is installed on the inner side of the connecting plate 21. Fasteners are inserted into the fastening holes 22 and the fasteners securely fix the first positioning member 4 or the second positioning member 5 to the inner side of the connecting plate 21.

[0026] The first positioning member 4 is a block structure with a semi-circular groove 41 on it. The semi-circular groove 41 is used to position the end of the main tube 11.

[0027] The second positioning component 5 consists of a straight plate 51 and a right-angle plate 52. The right-angle plate 52 is fixed to the side of the straight plate 51. The straight plate 51 is fixed to the inside of the connecting plate 21 by fasteners. The vertical space inside the right-angle plate 52 is used to position the end of the main tube 11.

[0028] This utility model also includes a cutting tool 6, which is mounted on a tool holder 7. During the rotation of the Y-shaped tee 1 driven by the lathe chuck, the cutting tool 6 can machine annular grooves 13 on the outer ends of the main pipe 11 and the branch pipe 12.

[0029] The specific working principle of this utility model is as follows: like Figure 8 As shown, when machining the groove 13 at the end of the main pipe 11 of the Y-type tee 1, the device uses the first positioning element 4; one end of the main pipe 11 is axially positioned by the first positioning element 4, and the pipe wall at the other end of the main pipe 11 is radially positioned by the clamping groove 24. The branch pipe 12 is clamped by the arc groove 26 to form a complete ring clamping force to prevent the Y-type tee 1 from jumping or loosening during rotation; the tool 6 machines the groove 13 on the pipe end of the main pipe 11 during the feeding process.

[0030] like Figure 9 As shown, when machining the groove 13 at the end of the branch pipe 12 of the Y-type tee 1, the device uses the second positioning element 5; one end of the main pipe 11 is axially positioned by the second positioning element 5, the outer wall of the main pipe 11 is clamped by the arc groove 26, and the pipe wall of the branch pipe 12 is radially positioned by the clamping groove 24; the tool 6 machines the groove 13 on the end of the branch pipe 12 during the feeding process.

[0031] This invention uses a contour-following, multi-point special fixture to stably transform an irregularly shaped and difficult-to-clamp Y-shaped tee into a rotating body that can be rotated on a lathe. This allows for efficient and precise machining of the annular groove at the pipe end using the standard cutting motion of the lathe (workpiece rotation, tool linear feed).
