Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and more specifically, to a steel pipe end grinding machine. Background Technology

[0002] Steel pipes are steel materials with hollow cross sections, whose length is much greater than their diameter or circumference. During the production process of steel pipes, burrs, uneven or irregular parts will appear at their ends. Therefore, a grinding machine is used to grind them to ensure that the ends of the steel pipes meet the required size and shape requirements.

[0003] Traditional end-grinding machines are typically designed for steel pipes of fixed dimensions and cannot adapt to steel pipes of different diameters or lengths, resulting in poor equipment versatility. Furthermore, the steel pipes are prone to shifting during the grinding process, leading to uneven grinding or damage to the steel pipes. Manual adjustment of the clamping position and grinding angle is required, which is cumbersome and inefficient. In view of this, we propose a steel pipe end-grinding machine. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a steel pipe end grinding machine. It solves the problems that existing grinding machines are usually designed for steel pipes of fixed size and cannot adapt to steel pipes of different diameters or lengths, resulting in poor equipment versatility. Furthermore, the steel pipe is prone to displacement during the grinding process, leading to uneven grinding or damage to the steel pipe. The machine also requires manual adjustment of the clamping position and grinding angle, which is cumbersome and inefficient.

[0005] To achieve the above objectives, this utility model provides a steel pipe end grinding machine, including a working platform. A guide rail is mounted on the upper surface of the working platform, and an mounting plate is slidably fitted above the guide rail. A groove is formed on the upper surface of the guide rail, and an electric telescopic rod is mounted on the side wall of the guide rail. The output end of the electric telescopic rod is disposed inside the groove and connected to the bottom surface of the mounting plate. A clamping assembly is mounted on the side wall of the mounting plate. A fixing frame is mounted on the upper surface of the working platform, and a grinding assembly is mounted on the upper surface of the fixing frame. In summary:

[0006] While the clamping assembly limits and fixes steel pipes of different sizes, it ensures that the center of each steel pipe is on the same horizontal line as the center of the grinding assembly for grinding.

[0007] The beneficial effects of this utility model are:

[0008] The clamping assembly accommodates steel pipes of varying sizes, expanding its adaptability. The center alignment design between the clamping and grinding assemblies ensures grinding precision. The guide rail and groove design enhance the accuracy and stability of the mounting plate's movement. The electrically operated telescopic rod allows for quick adjustment of the mounting plate's position to accommodate steel pipes of different lengths.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] As a further improvement to this technical solution, the clamping assembly includes a support plate and several clamping blocks. The bottom end of the support plate is connected to the side wall of the mounting plate. Two clamping blocks are symmetrically arranged and can move relative to the support plate. A clamping groove is formed on the inner surface of each clamping block. The clamping groove is configured as a V-shaped groove structure, and a sponge pad is provided inside the clamping groove.

[0011] The beneficial effects of adopting the above-mentioned further solutions are: V-groove design: automatically adapts to steel pipes of different diameters without manual adjustment; sponge pad: protects the surface of the steel pipe and prevents scratches.

[0012] As a further improvement to this technical solution, the support plate has a track groove on its surface, and a ball screw is installed inside the track groove. The ball screw is configured as a combination structure of two reverse spiral grooves. Two moving blocks are installed on the outer wall of the ball screw, each located on one of the two reverse spiral grooves. The two moving blocks move relative to each other in a straight line within the track groove due to the rolling of the balls between the ball screw and the screw nut inside the moving blocks. The outer surfaces of the two moving blocks are connected to the side walls of two clamping blocks, respectively. The top of the ball screw extends through the track groove to the outside, and a torsion block is installed at the top of the ball screw.

[0013] The advantage of adopting the above-mentioned further solution is that by using a ball screw and a moving block, the synchronous relative movement of the clamping block is achieved through a rotating torsion block, which is simple to operate and provides uniform clamping force.

[0014] As a further improvement to this technical solution, a limiting plate is installed on the upper surface of the fixing frame, and a stabilizing plate is installed at the edge of the upper surface of the fixing frame. The grinding assembly includes a drive motor and a grinding disc. A connecting rod is installed at the output end of the drive motor. The connecting rod passes through the limiting plate and the stabilizing plate in sequence, and the top end of the connecting rod is connected to the grinding disc.

[0015] The advantages of adopting the above-mentioned further solutions are that the limiting plate and stabilizing plate improve the stability of the grinding disc and ensure grinding accuracy; the drive motor provides efficient power, allowing the grinding disc to complete grinding quickly. The design of the clamping assembly and grinding assembly ensures that the center of steel pipes of different sizes is always aligned with the center of the grinding disc, improving grinding accuracy and avoiding uneven grinding or damage caused by steel pipe misalignment.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In this steel pipe end grinding machine, on the one hand, the V-groove double-inclined ball screw design can accommodate steel pipes of different diameters. The synchronous relative movement of the clamping blocks is achieved through the rotating torsion block, which is easy to operate and provides uniform clamping force. The geometric self-centering principle ensures that the steel pipe axis is aligned with the grinding components, avoiding uneven grinding or damage caused by steel pipe misalignment, reducing errors and improving grinding accuracy. On the other hand, the sponge pad buffers the clamping pressure and avoids scratches on the steel pipe surface. Attached Figure Description

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Please see Figures 1-4As shown, this embodiment provides a steel pipe end grinding machine, including a working platform 100. Considering that traditional grinding machines are usually designed for steel pipes of fixed size and cannot adapt to steel pipes of different diameters or lengths, resulting in poor equipment versatility, and that the steel pipe is prone to displacement during grinding, leading to uneven grinding or damage to the steel pipe, requiring manual adjustment of the clamping position and grinding angle, which is cumbersome and inefficient, the following is specifically provided: A guide rail 101 is installed on the upper surface of the working platform 100, and a mounting plate 1010 is slidably fitted above the guide rail 101. A groove is formed on the upper surface of the guide rail 101, and an electric telescopic rod 1011 is installed on the side wall of the guide rail 101. The output end of the electric telescopic rod 1011 is located inside the groove and connected to the bottom surface of the mounting plate 1010. A clamping assembly 200 is installed on the side wall of the mounting plate 1010. A fixing frame 102 is installed on the upper surface of the working platform 100, and a grinding assembly 300 is installed on the upper surface of the fixing frame 102.

[0026] While the clamping component 200 limits and fixes steel pipes of different sizes, it also ensures that the center of the steel pipes of different sizes is on the same horizontal line as the center of the grinding component 300 for grinding.

[0027] The improvement in this embodiment is as follows:

[0028] The clamping assembly 200 adapts to clamping and fixing steel pipes of different sizes, increasing its adaptability. The center alignment design between the clamping assembly 200 and the grinding assembly 300 ensures grinding accuracy. The guide rail 101 and its groove design improve the accuracy and stability of the mounting plate 1010's movement. The electric telescopic rod 1011 allows for quick adjustment of the mounting plate 1010's position, accommodating steel pipes of different lengths.

[0029] First, to clamp and fix steel pipes of different sizes and improve the adaptability of the equipment, the clamping assembly 200 includes a support plate 201 and several clamping blocks 202. The bottom end of the support plate 201 is connected to the side wall of the mounting plate 1010. Two clamping blocks 202 are symmetrically arranged and can move relative to the support plate 201. A clamping groove 2020 is formed on the inner surface of the clamping block 202. The clamping groove 2020 is set with a V-shaped groove structure, and a sponge pad is placed inside the clamping groove 2020. The support plate 201 has a track groove 2010 on its surface. A ball screw 2011 is installed inside the track groove 2010. The ball screw 2011 is configured as a combination of two reverse spiral grooves. Two moving blocks 2012 are installed on the outer wall of the ball screw 2011, one on each of the two reverse spiral grooves. The two moving blocks 2012 move relative to each other in a straight line within the track groove 2010 by the rolling of the balls between the ball screw 2011 and the screw nut inside the moving block 2012. The outer surfaces of the two moving blocks 2012 are connected to the side walls of two clamping blocks 202, respectively. The top of the ball screw 2011 extends through the track groove 2010 to the outside, and a torsion block 2013 is installed at the top of the ball screw 2011.

[0030] By rotating the torsion block 2013, the ball screw 2011 is driven to rotate, and the two moving blocks 2012 move in a straight line relative to each other along the track groove 2010, pushing the two clamping blocks 202 to move closer together. The V-shaped clamping groove 2020 and the sponge pad clamp the steel pipe, while ensuring that the center of the steel pipe is aligned with the center of the grinding disc 302. Then, the electric telescopic rod 1011 is activated, pushing the mounting plate 1010 to slide along the guide rail 101, so that the end of the steel pipe is accurately aligned with the grinding disc 302.

[0031] Secondly, in order to realize the grinding operation of the steel pipe end, a limit plate 1020 is installed on the upper surface of the fixed frame 102, and a stabilizing plate 1021 is installed at the edge of the upper surface of the fixed frame 102. The grinding assembly 300 includes a drive motor 301 and a grinding disc 302. A connecting rod 3010 is installed at the output end of the drive motor 301. The connecting rod 3010 passes through the limit plate 1020 and the stabilizing plate 1021 in sequence, and the top end of the connecting rod 3010 is connected to the grinding disc 302.

[0032] By starting the drive motor 301, the grinding disc 302 rotates at high speed and grinds the end of the steel pipe to remove burrs or uneven parts. During the grinding process, the clamping component 200 keeps the steel pipe stable to ensure grinding accuracy.

[0033] In practical use, the steel pipe end grinding machine of this utility model is used to place the steel pipe on the V-shaped clamping groove 2020 of the lower clamping block 202, with the end of the steel pipe close to the grinding disc 302; the rotating torsion block 2013 drives the ball screw 2011 to rotate, and the two moving blocks 2012 move in a relatively linear motion along the track groove 2010, pushing the two clamping blocks 202 to move closer to the middle, and the V-shaped clamping groove 2020 and the sponge pad clamp the steel pipe, while ensuring that the center of the steel pipe is aligned with the center of the grinding disc 302. Next, the electric telescopic rod 1011 is activated, pushing the mounting plate 1010 to slide along the guide rail 101, so that the end of the steel pipe is accurately aligned with the grinding disc 302. The limiting plate 1020 and the stabilizing plate 1021 fix the position of the grinding disc 302 to prevent shaking during the grinding process. The drive motor 301 is activated, and the grinding disc 302 rotates at high speed. The grinding disc 302 grinds the end of the steel pipe to remove burrs or uneven parts. During the grinding process, the clamping component 200 keeps the steel pipe stable to ensure grinding accuracy. After the grinding is completed, the drive motor 301 is turned off, the electric telescopic rod 1011 retracts the mounting plate 1010, and the ground steel pipe is moved away from the grinding disc 302. The torsion block 2013 is rotated to release the clamping block 202 and the steel pipe is taken out.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
