Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel pipe processing equipment, specifically a polishing device for stainless steel pipe processing. Background Technology

[0002] In modern industrial production, stainless steel pipes are widely used in many fields such as building decoration, food processing, medical devices, and petrochemicals due to their excellent corrosion resistance, high strength, and aesthetics. However, during the manufacturing process, stainless steel pipes often have defects such as oxide scale, scratches, and burrs on their surface, which not only affect the appearance quality but may also reduce the corrosion resistance and service life of the pipes. Therefore, polishing has become an indispensable key step in the processing of stainless steel pipes.

[0003] The existing patent document CN220561231U discloses a polishing device for processing stainless steel pipes. This utility model can stably fix the stainless steel pipe body through a fixed mechanism to prevent movement during polishing. The moving mechanism drives the polishing wheel to move stably for polishing, thereby polishing the stainless steel pipe body more evenly.

[0004] However, existing polishing equipment for stainless steel pipe processing is not convenient for quick replacement of polishing heads according to processing needs. Traditional polishing equipment mostly adopts a single-head polishing structure. When faced with polishing tasks with different materials and roughness requirements, operators need to use special tools to disassemble, replace, and recalibrate. The entire process involves multiple steps such as bolt disassembly, centering and positioning, and torque tightening. Each replacement takes a long time, which seriously restricts processing efficiency. In addition, the mechanical wear caused by frequent disassembly and assembly will accelerate the aging of fixtures and connecting parts, shorten the equipment maintenance cycle, increase hidden production costs, and make it difficult to meet the continuous and automated production requirements pursued by modern industry. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this utility model is to provide a polishing device for stainless steel pipe processing, so as to solve the problem mentioned in the background art that the existing polishing devices for stainless steel pipe processing are not convenient to quickly change the polishing head according to processing needs.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a polishing device for processing stainless steel pipes, comprising a machine body, a support plate vertically arranged above the machine body, and a rotary motor installed on one side of the support plate;

[0009] The drive end of the rotary motor is fixedly connected to a drive shaft. A mounting plate is sleeved on the outer surface of the drive shaft. Multiple polishing motors are arranged in a ring array on the outer surface of the mounting plate. The drive end of each polishing motor is connected to a connecting shaft. A polishing head is mounted on the end of the connecting shaft away from the polishing motor.

[0010] As a further improvement to the above solution, an adjustment motor is installed on one side of the machine body, and the transmission end of the adjustment motor passes through the machine body and is fixedly connected to a first positioning seat.

[0011] As a further improvement to the above solution, a telescopic cylinder is installed on the side of the machine body away from the regulating motor, and the transmission end of the telescopic cylinder is fixedly connected to a connecting block through the machine body.

[0012] As a further improvement to the above solution, a second positioning seat is rotatably connected to the side of the connecting block away from the telescopic cylinder. The first positioning seat and the second positioning seat are coaxially corresponding, and multiple electric telescopic rods are distributed in a circular array on the outer surface of both the first positioning seat and the second positioning seat.

[0013] As a further improvement to the above solution, the transmission end of the electric telescopic rod extends to the inner side of the first positioning seat and the second positioning seat, and the end is connected to an arc-shaped positioning block.

[0014] As a further improvement to the above solution, support columns are symmetrically arranged on both sides of the upper surface of the body, and linear guide rails are installed on the top of the support columns.

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

[0017] 1. This polishing device for stainless steel pipe processing is designed to quickly switch polishing heads in different positions by rotating the mounting plate through a rotary motor. Compared with the traditional method of manually disassembling and replacing polishing heads, this structure can complete the switching of polishing heads in a short time, significantly reducing equipment downtime and improving production efficiency. At the same time, polishing heads of different specifications and materials can be pre-configured on the mounting plate and automatically rotated to the working position according to the actual polishing needs, realizing continuous operation of multiple processes such as rough grinding and fine grinding, further improving the continuity of the processing flow.

[0018] 2. This polishing device for stainless steel pipe processing, through the combination structure of the first positioning seat, the second positioning seat, the electric telescopic rod, and the arc-shaped positioning block, can automatically adjust the positioning and clamping range according to the diameter of the stainless steel pipe. Compared with the traditional fixed-specification clamping device, it does not require frequent manual replacement of clamps and can be adapted to stainless steel pipes of various diameters, significantly enhancing the versatility and applicability of the equipment. In addition, the design of the arc-shaped positioning block increases the contact area with the surface of the steel pipe, improves the clamping stability, effectively prevents the steel pipe from shaking during the polishing process, and ensures the polishing quality.

[0019] 3. The polishing device for stainless steel pipe processing uses a moving adjustment system composed of linear guide rails, electric sliders and hydraulic telescopic cylinders to precisely control the position of the support plate and polishing mechanism in the horizontal and vertical directions. During the polishing process, it can flexibly adjust the relative position of the polishing mechanism and the steel pipe to ensure that the polishing head fits the surface of the steel pipe. It can also make adaptive adjustments according to steel pipes of different lengths and curvatures to ensure polishing accuracy. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 4The present invention provides a technical solution: a polishing device for processing stainless steel pipes, including a body 1, a support plate 2 vertically arranged above the body 1, and a rotary motor 3 installed on one side of the support plate 2.

[0027] A drive shaft 4 is fixedly connected to the transmission end of the rotary motor 3. A mounting plate 5 is sleeved on the outer surface of the drive shaft 4. Multiple polishing motors 6 are arranged in a ring array on the outer surface of the mounting plate 5. A connecting shaft 7 is connected to the transmission end of each polishing motor 6. A polishing head 8 is assembled at the end of the connecting shaft 7 away from the polishing motor 6.

[0028] The operator starts the rotary motor 3, which drives the drive shaft 4 to rotate synchronously, causing the mounting plate 5 and the polishing motor 6 of the ring array to rotate. According to the polishing requirements, different specifications of polishing heads 8 can be quickly switched to the working position, such as rotating the coarse grinding head directly above the stainless steel pipe for preliminary polishing.

[0029] An adjustment motor 9 is installed on one side of the body 1. The transmission end of the adjustment motor 9 passes through the body 1 and is fixedly connected to a first positioning seat 10. A telescopic cylinder 11 is installed on the side of the body 1 away from the adjustment motor 9. A connecting block 12 is fixedly connected to the transmission end of the telescopic cylinder 11. A second positioning seat 13 is rotatably connected to the side of the connecting block 12 away from the telescopic cylinder 11. The first positioning seat 10 and the second positioning seat 13 are coaxially corresponding. Multiple electric telescopic rods 14 are arranged in a circular array on the outer surfaces of the first positioning seat 10 and the second positioning seat 13. The transmission end of the electric telescopic rod 14 extends to the inner side of the first positioning seat 10 and the second positioning seat 13, and the end is connected to an arc-shaped positioning block 15. Support columns 16 are symmetrically arranged on both sides of the upper surface of the body 1. A linear guide rail 17 is installed on the top of the support column 16. An electric slider 18 is arranged inside the linear guide rail 17. A hydraulic telescopic cylinder 19 is vertically installed at the bottom end of the electric slider 18. The support plate 2 is located at the transmission end of the bottom end of the hydraulic telescopic cylinder 19.

[0030] When using this device to polish stainless steel pipes, the stainless steel pipe to be processed is first placed above the machine body 1. At this time, the telescopic cylinder 11 is automatically activated, pushing the connecting block 12 to move the second positioning seat 13 towards the first positioning seat 10, precisely aligning the two ends of the steel pipe. Then, the electric telescopic rods 14 on the outer surfaces of the two positioning seats extend synchronously, and the arc-shaped positioning blocks 15 at the ends fit tightly against the outer wall of the steel pipe. The clamping force is automatically adjusted by the feedback from the pressure sensor (not shown in the figure), realizing adaptive and stable clamping of stainless steel pipes of different diameters, effectively avoiding pipe shaking during the polishing process. The electric slider 18 is moved horizontally on the linear guide rail 17 by operation. The hydraulic telescopic cylinder 19 drives the support plate 2 to rise and fall vertically, so that the polishing head 8 is precisely positioned to the area to be polished. During the polishing operation, the polishing motor 6 drives the polishing head 8 to rotate at high speed. At the same time, the hydraulic telescopic cylinder 19 precisely controls the contact pressure between the polishing head 8 and the surface of the stainless steel pipe to ensure uniform polishing effect. During this process, the adjustment motor 9 drives the first positioning seat 10 to rotate at a uniform speed, and drives the second positioning seat 13 to rotate synchronously through the stainless steel pipe. The rotating pair design between the second positioning seat 13 and the connecting block 12 ensures the smoothness of the rotation process, so that the steel pipe is fully polished during the flipping process, effectively eliminating polishing blind spots, and finally achieving high-precision processing.

[0031] Working Principle: When using this device for stainless steel pipe polishing, the stainless steel pipe to be processed is first placed above the machine body 1. At this time, the telescopic cylinder 11 automatically starts, pushing the connecting block 12 to move the second positioning seat 13 towards the first positioning seat 10, precisely aligning both ends of the steel pipe. Then, the electric telescopic rods 14 on the outer surfaces of the two positioning seats extend synchronously, and the arc-shaped positioning blocks 15 at the ends tightly fit against the outer wall of the steel pipe. The clamping force is automatically adjusted through feedback from a pressure sensor (not shown in the figure), achieving adaptive and stable clamping for stainless steel pipes of different diameters, effectively preventing the pipe from shaking during polishing. After positioning is completed, the operator starts the rotary motor 3, and the drive shaft 4 rotates synchronously, driving the mounting plate 5 and the polishing motors 6 in the ring array to rotate. According to the polishing requirements, different specifications of polishing heads 8 can be quickly switched. In the working position, the coarse grinding head is rotated directly above the stainless steel tube for initial polishing. Subsequently, the electric slider 18 is moved horizontally on the linear guide rail 17, and the hydraulic telescopic cylinder 19 is controlled to drive the support plate 2 to rise and fall vertically, so that the polishing head 8 is precisely positioned in the area to be polished. During the polishing operation, the polishing motor 6 drives the polishing head 8 to rotate at high speed, while the hydraulic telescopic cylinder 19 precisely controls the contact pressure between the polishing head 8 and the surface of the stainless steel tube to ensure uniform polishing effect. During this process, the adjusting motor 9 drives the first positioning seat 10 to rotate at a uniform speed, and synchronously drives the second positioning seat 13 to rotate through the stainless steel tube. The rotating pair design between the second positioning seat 13 and the connecting block 12 ensures the smoothness of the rotation process, so that the steel tube receives full polishing during the flipping process, effectively eliminating polishing blind spots, and finally achieving high-precision processing.

Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
