Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipe processing technology, specifically a leveling device for pipe ends. Background Technology
[0002] Polyethylene pipes, also known as PE pipes, are most widely used in water supply and gas pipes. PE resin is polymerized from ethylene monomers. After production, the ends of polyethylene pipes are not always smooth. Due to installation requirements, the pipe ends need to be smooth and neat to ensure the sealing after pipe connection. Therefore, it is necessary to use a tool to process the pipe ends. Traditionally, when smoothing the pipe ends, the pipe is placed on a workbench and then trimmed with a tool. During the trimming process, the pipe needs to be rotated to complete the circumferential trimming. However, manual processing has low precision and cannot accurately ensure that the processed end is perpendicular to the pipe axis, thus affecting the sealing of subsequent pipe connections. Therefore, improvements are needed to address the above problems. Utility Model Content
[0003] To achieve the above objectives, this utility model provides the following technical solution: a leveling device for pipe ends, comprising a platform, four support legs fixedly installed at the bottom of the platform, an adjustable support plate installed at the top of the platform, a groove opened at the top of the support plate, a plurality of rollers 1 evenly spaced on both sides inside the groove, a first motor for driving the rollers 1 installed at one end of the support plate, a vertical plate fixedly installed at the top of the platform, a fixing plate fixedly installed at the top of the vertical plate, a plurality of rollers 2 rotatably installed at equal distances at the bottom of the fixing plate, and a movable horizontal cutting blade installed on one side of the vertical plate.
[0004] Preferably, four inverted T-shaped inserts are movably installed through the middle of the platform. The tops of the four inverted T-shaped inserts are fixedly connected to the bottom of the support plate, and springs are sleeved on the lower parts of the four inverted T-shaped inserts. The two ends of the springs are fixedly connected to the bottom of the platform and the lower end of the inverted T-shaped inserts, respectively. Two right-angled trapezoidal pressure blocks are symmetrically fixedly installed on the bottom of the support plate.
[0005] Preferably, the top of the platform has two symmetrically formed grooves, and a bidirectional threaded shaft is rotatably installed between the two grooves. The bidirectional threaded shaft is threadedly connected to an inverted T-shaped extrusion block inside each of the two grooves. The upper part of each of the two inverted T-shaped extrusion blocks has a sloping structure, and the two sloping structures are respectively connected to the sloping surfaces of the two right-angled trapezoidal pressure blocks. A second motor is installed at one end of the platform, and the output end of the second motor is connected to one end of the bidirectional threaded shaft.
[0006] Preferably, the inner sides of the pallet are provided with wheel grooves that communicate with the groove at equal intervals. The number of wheel grooves is the same as the number of rollers. An installation shaft is rotatably installed between the wheel grooves on the same side of the pallet. Roller is fixedly installed on the surface of the installation shaft located inside the wheel groove. The output end of the first motor is connected to one end of one of the installation shafts.
[0007] Preferably, two insert rods are movably installed through one end of the vertical plate, the cutting blade is fixedly installed between one end of the two insert rods, and an electric telescopic cylinder located between the two insert rods is installed at one end of the vertical plate, with the telescopic end of the electric telescopic cylinder being fixedly connected to the cutting blade.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: This pipe end leveling device has clamping and fixing and rotation adjustment functions, which can effectively fix and reliably rotate the pipe whose end needs to be leveled, thereby effectively ensuring the accuracy of the processing and effectively ensuring that the end of the pipe is perpendicular to the pipe axis after processing. The pipe is placed inside the groove and between the surface of the first roller; then the second motor is started to rotate the bidirectional threaded shaft. The rotation of the bidirectional threaded shaft will cause the two inverted T-shaped extrusion blocks to move relative to each other. The two inverted T-shaped extrusion blocks that move relative to each other will squeeze the two right-angled trapezoidal pressure blocks, causing the pallet to move upward. The pallet can move upward stably through the four inverted T-shaped inserts and compress the four springs. The upward movement of the pallet will drive the pipe to move towards the fixed plate, and finally make the pipe abut against the second roller, thereby abutting and clamping the pipe. Then, by starting the first motor, one of the mounting shafts is rotated. The rotation of the mounting shaft will drive the first roller on it to rotate. The rotation of the first roller on the mounting shaft will drive the pipe to rotate through the other rotatable mounting shaft and its first roller, as well as through the second roller.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0012] Depend on Figures 1 to 4 The present invention includes a platform 1, four support legs 2 fixedly installed at the bottom of the platform 1, an adjustable support plate 3 installed at the top of the platform 1, a groove 4 opened at the top of the support plate 3, a plurality of rollers 5 evenly spaced on both sides inside the groove 4, a first motor 6 for driving the rollers 5 installed at one end of the support plate 3, a vertical plate 7 fixedly installed at the top of the platform 1, a fixing plate 8 fixedly installed at the top of the vertical plate 7, a plurality of rollers 9 rotatably installed at equal distances at the bottom of the fixing plate 8, the rollers 9 being located directly above the groove 4, and a movable horizontal cutting blade 10 installed on one side of the vertical plate 7.
[0013] Four inverted T-shaped inserts 11 are movably installed through the middle of the platform 1. The tops of the four inverted T-shaped inserts 11 are fixedly connected to the bottom of the support plate 3, and springs 12 are sleeved on the lower parts of the four inverted T-shaped inserts 11. The two ends of the springs 12 are fixedly connected to the bottom of the platform 1 and the lower ends of the inverted T-shaped inserts 11, respectively. Two right-angled trapezoidal pressure blocks 13 are symmetrically fixedly installed on the bottom of the support plate 3. Two sliding grooves 14 are symmetrically opened on the top of the platform 1. A bidirectional threaded shaft 15 is rotatably installed between the two sliding grooves 14. Inverted T-shaped extrusion blocks 16 are threadedly connected to the bidirectional threaded shaft 15 inside the two sliding grooves 14. The upper part of the two inverted T-shaped extrusion blocks 16 is provided with an inclined structure. Two inclined structures are respectively connected to the inclined surfaces of two right-angled trapezoidal pressure blocks 13. A second motor 17 is installed at one end of the platform 1. The output end of the second motor 17 is connected to one end of the bidirectional threaded shaft 15, so as to effectively place and clamp the pipe. The inner sides of the support plate 3 are equally spaced wheel grooves 18 that communicate with the groove 4. The number of wheel grooves 18 is the same as the number of rollers 5. The mounting shaft 19 is rotatably installed between the wheel grooves 18 on the same side of the support plate 3. The rollers 5 are fixedly installed on the surface of the mounting shaft 19 located inside the wheel groove 18. The output end of the first motor 6 is connected to one end of one of the mounting shafts 19, so as to effectively rotate the pipe.
[0014] Specifically, the pipe is placed inside the groove 4 and between the surface of the roller 5; then the second motor 17 is started to rotate the bidirectional threaded shaft 15. The rotation of the bidirectional threaded shaft 15 will cause the two inverted T-shaped extrusion blocks 16 to move relative to each other. The two inverted T-shaped extrusion blocks 16 will extrude the two right-angled trapezoidal pressure blocks 13, causing the support plate 3 to move upward. The support plate 3 can move upward stably through the four inverted T-shaped inserts 11 and compress the four springs 12. The upward movement of the support plate 3 will drive the pipe to move towards the fixed plate 8, and finally make the pipe abut against the roller 9, thereby abutting and clamping the pipe. Then, by starting the first motor 6, one of the mounting shafts 19 is rotated. The rotation of the mounting shaft 19 will drive the roller 5 on it to rotate. The rotation of the roller 5 on the mounting shaft 19 will drive the pipe to rotate through the other rotatable mounting shaft 19, the roller 5 on it, and the roller 9.
[0015] Two insert rods 20 are movably installed through one end of the vertical plate 7. The cutting blade 10 is fixedly installed between one end of the two insert rods 20. An electric telescopic cylinder 21 located between the two insert rods 20 is installed at one end of the vertical plate 7. The telescopic end of the electric telescopic cylinder 21 is fixedly connected to the cutting blade 10, thereby enabling effective cutting and smoothing of the pipe end.
[0016] Specifically, when the support plate 3 moves upward and clamps the pipe with the roller 9, the end of the pipe is aligned with the cutting blade 10. At the same time, when the pipe rotates, the electric telescopic cylinder 21 is activated to push the cutting blade 10 toward the rotating pipe, so that the cutting blade 10 performs a flat cutting operation on the end of the rotating pipe.
[0017] This pipe end leveling device has clamping and fixing functions as well as rotation adjustment. It can effectively fix and reliably rotate and adjust the pipe end that needs to be leveled, thereby ensuring the accuracy of the processing and ensuring that the end of the pipe is perpendicular to the pipe axis after processing. At the same time, the pipe end leveling device has a simple structural design, is convenient to use and operate, and has stable and reliable fixing and rotation. Its performance can meet the requirements of pipe end leveling, thereby effectively ensuring the sealing of the pipe connection.
