Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline treatment technology, and in particular to a pipeline edge grinding device. Background Technology
[0002] As is well known, PVC pipes, or rigid polyvinyl chloride pipes, are made by extruding polyvinyl chloride resin with stabilizers, lubricants, and other additives using a hot-pressing method. They were among the earliest plastic pipe materials developed and applied. PVC pipes are commonly used, and during production, they need to be cut and then the edges at both ends are ground. Traditional grinding equipment grinds one end of the pipe, then disassembles and re-fixes it before grinding the other end. This process is extremely inefficient, and the re-fixing process increases the number of clamping marks on the outside of the pipe, potentially affecting its strength. Utility Model Content
[0003] The purpose of this invention is to solve the problem that the existing technology involves grinding one end of a pipe, disassembling the pipe, re-fixing it, and then grinding the other end of the pipe, which is very inefficient. Therefore, this invention proposes a pipe edge grinding device.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:

Fixed plates are provided on both sides of the moving block. A pneumatic telescopic rod is provided at one end of each of the two fixed plates. The extension rods of the two pneumatic telescopic rods abut against the outer ring of the fixed ring.
[0007] Preferably, the two pneumatic telescopic rods are arranged symmetrically around the moving block.
[0008] Preferably, one end of the extension rod of both pneumatic telescopic rods is set to be arc-shaped.
[0009] Preferably, an indicator groove is provided on the outer side of the fixing ring, and one end of the extension rod of each of the two pneumatic telescopic rods is pressed against the indicator groove.

[0012] Preferably, the outer side of the moving block is provided with a wear-resistant coating.
[0013] The present invention provides a pipe edge grinding device, which has the following advantages: after grinding one end of the pipe, the pipe does not need to be re-fixed when grinding the other end, thereby improving the efficiency of pipe grinding. In addition, the clamping marks on the outside of the pipe will be reduced, reducing the adverse factors that affect the strength of the pipe. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Example 1: Refer to Figure 1-4 A pipe edge grinding device includes a body 1, a grinding component 2 is provided on one side of the body 1, a fixing ring 3 is placed on one side of the body 1, a plurality of hydraulic telescopic rods 4 are provided inside the fixing ring 3, a pipe 5 is clamped between the extension rods of the plurality of hydraulic telescopic rods 4, a moving block 6 is provided on one side of the top of the body 1, a moving mechanism 13 is provided between the moving block 6 and the body 1, and an adjustment mechanism is provided between the moving block 6 and the fixing ring 3;
[0021] The adjustment mechanism includes a servo motor 7 located at the bottom of the moving block 6. The output shaft of the servo motor 7 is mounted on the outer ring of the fixed ring 3. Fixed plates 8 are provided on both sides of the moving block 6. Pneumatic telescopic rods 9 are provided at one end of each of the two fixed plates 8. The extension rods of the two pneumatic telescopic rods 9 abut against the outer ring of the fixed ring 8.
[0022] Combined with appendix Figure 1-3 The moving mechanism 13 is a long slot opened on the machine body 1. A lead screw is installed in the long slot through a bearing. One end of the moving block 6 is slidably installed in the long slot. The lead screw thread passes through the moving block 6, so that the fixed ring 3 moves more stably when the moving mechanism 13 moves with the moving block 6 on the machine body 1.
[0023] After aligning the pipe 5 to be ground with the center of the fixing ring 3, activate several hydraulic telescopic rods 4. The hydraulic telescopic rods 4 will clamp the pipe 5. Then, activate the moving mechanism to move one end of the pipe 5 towards the grinding assembly 2, allowing one end of the pipe 5 to be ground. After one end of the pipe 5 is ground, activate the moving mechanism to return the fixing ring 3 to its original position. Then, activate the two pneumatic telescopic rods 9, moving the extension rods of the two pneumatic telescopic rods 9 away from the outside of the fixing ring 3. Finally, activate the servo motor 7. The output shaft of the servo motor 7 will rotate the fixing ring 3, causing the other end of the pipe 5 to be ground. After aligning one end with the grinding component 2, the extension rods of the two pneumatic telescopic rods 9 are pressed against the outside of the fixing ring 3. Then, the moving mechanism is activated to move the other end of the pipe 5 toward the grinding component 2, so that the other end of the pipe 5 is also ground. This way, when grinding the other end of the pipe 5 after grinding one end, the pipe 5 does not need to be re-fixed, avoiding repeated clamping of the pipe 5, thereby improving the grinding efficiency of the pipe 5. Moreover, the clamping marks on the outside of the pipe 5 will be reduced, making the strength of the pipe 5 less likely to be affected.
[0024] Example 2: An optimization based on Example 1, with reference to... Figure 1-4 Two pneumatic telescopic rods 9 are symmetrically arranged around the moving block 6. One end of the extension rod of each pneumatic telescopic rod 9 is set in an arc shape. An indicator groove 10 is provided on the outside of the fixing ring 3. One end of the extension rod of each pneumatic telescopic rod 9 is pressed against the indicator groove 10.
[0025] Combined with appendix Figure 2-4 An indicator groove 10 is provided so that the bottom of the extension rods of the two pneumatic telescopic rods 9 are round, thereby reducing the difficulty of aligning the pipe 5 clamped in the fixing ring 3 in embodiment 1 with the grinding assembly 2, thus facilitating the grinding of the pipe 5.
[0026] Example 3: An optimization based on Example 1, with reference to... Figure 1-4Each of the extension rods of the hydraulic telescopic rods 4 is equipped with an auxiliary clamping block 11. Each of the auxiliary clamping blocks 11 has a slot 12 at its bottom. The bottom edge of each of the auxiliary clamping blocks 11 is arc-shaped. The outer side of the moving block 6 is provided with a wear-resistant coating.
[0027] The wear-resistant coating is formed by nitriding, which improves the mechanical properties of the moving block 6 and thus increases its service life.
[0028] By setting auxiliary clamping blocks 11 in conjunction with slots 12, the bottom edges of the auxiliary clamping blocks 11 are all opened into arc shapes, which increases the area of the auxiliary clamping blocks 11 in contact with the pipe 5, thereby increasing the clamping area of the hydraulic telescopic rods 4 on the pipe 5 in embodiment 1, thereby improving the fixing effect on the pipe 5.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
