Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel pipe polishing technology, specifically a steel pipe inner surface polishing machine. Background Technology
[0002] Currently, when polishing the inner surface of steel pipes, the steel pipe is usually fixed, and then the polishing wheel moves inside the steel pipe to complete the polishing. After polishing, the polishing wheel needs to be withdrawn from the steel pipe along the original path. When the steel pipe is long, the polishing wheel takes a long time to withdraw from the steel pipe, which reduces the processing efficiency of the steel pipe. In view of the above situation, we will carry out technical innovation based on the existing steel pipe inner surface polishing machine. Utility Model Content
[0003] The purpose of this invention is to provide a steel pipe inner surface polishing machine to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a steel pipe inner surface polishing machine, comprising: The base contains a bidirectional lead screw, and a set of internally threaded sliders are screwed to the left and right sides of the outer side wall of the bidirectional lead screw. An L-plate and a hydraulic pipe clamping machine are respectively placed on the left and right sides of the top of the base. A first servo motor is located on the left side of the L-plate, and the output end of the first servo motor passes through the right side of the L-plate and is connected to a connecting shaft. A polishing wheel is located on the right side of the connecting shaft. A steel pipe is clamped and fixed inside the hydraulic pipe clamping machine, and the polishing wheel corresponds to the steel pipe. Two sets of connecting plates are evenly arranged between the L-plate, the hydraulic pipe clamping machine, and the two sets of internally threaded sliders.
[0005] Preferably, rollers are evenly arranged at the bottom of the L-plate and the hydraulic pipe clamping machine, and the rollers are located at the top of the base.
[0006] Preferably, a sliding groove is provided through the front side of the base, the bidirectional lead screw is rotatably disposed in the sliding groove, and the internal threaded slider is slidably disposed in the sliding groove.
[0007] Preferably, a second servo motor is provided on the left side of the base, and the output end of the second servo motor is connected to a bidirectional lead screw through a sliding groove.
[0008] Preferably, two sets of cells are evenly arranged on the rear side of the inner side wall of the support frame base, and a first support sleeve is sleeved on the outer side wall of the bidirectional lead screw, and the first support sleeve is disposed in the slide groove.
[0009] Preferably, a second support sleeve is rotatably sleeved on the outer side wall of the connecting shaft, and the second support sleeve is disposed on the top of the base.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a second servo motor to drive the polishing wheel and the steel pipe to move inward synchronously, which can significantly shorten the required travel distance of the polishing wheel and thus significantly shorten the overall length of the device. After polishing is completed, the second servo motor reverses to drive the polishing wheel and the steel pipe to move outward synchronously, allowing the polishing wheel to quickly exit from the steel pipe, thereby improving the processing efficiency of the steel pipe.
[0011] By installing the bidirectional lead screw inside the base, it is possible to effectively prevent polishing debris from contacting the bidirectional lead screw and affecting its normal operation, thereby improving the reliability of the device. Attached Figure Description

[0014] 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.
[0015] Please see Figures 1-3A steel pipe inner surface polishing machine includes a base 1. A bidirectional lead screw 23 is housed inside the base 1. A set of internally threaded sliders 12 are screwed onto the left and right sides of the outer side wall of the bidirectional lead screw 23. An L-plate 14 and a hydraulic pipe clamping machine 15 are respectively placed on the left and right sides of the top of the base 1. A first servo motor 21 is fixedly installed on the left side of the L-plate 14. The output end of the first servo motor 21 passes through the right side of the L-plate 14 and is connected to a connecting shaft 19. A polishing wheel 2 is fixedly installed on the right side of the connecting shaft 19. A steel pipe 17 is clamped and fixed inside the hydraulic pipe clamping machine 15. The steel pipe 17 is clamped and fixed using a hydraulic pipe clamping machine 15. The polishing wheel 2 corresponds to the steel pipe 17. Two sets of connecting plates 13 are evenly fixed between the L-plate 14, the hydraulic pipe clamping machine 15, and the two sets of internal threaded sliders 12. Rollers 16 are evenly fixed at the bottom of the L-plate 14 and the hydraulic pipe clamping machine 15, assisting the L-plate 14 and the hydraulic pipe clamping machine 15 in stable movement. The second servo motor 22 drives the bidirectional lead screw 23 to rotate, which in turn drives the two sets of internal threaded sliders 12 to move inward synchronously, thus connecting... Plate 13 drives L-plate 14 and hydraulic pipe clamping machine 15 to move inward synchronously, which in turn drives polishing wheel 2 and steel pipe 17 to move inward synchronously, so that polishing wheel 2 can move inside steel pipe 17. At the same time, the first servo motor 21 drives connecting shaft 19 to rotate, which in turn drives polishing wheel 2 to rotate. So when polishing wheel 2 is inserted into steel pipe 17, the rotating polishing wheel 2 can polish the inner surface of steel pipe 17. Roller 16 is located on the top of base 1. A sliding groove is opened through the front side of base 1, and bidirectional screw 23 is rotatably set in the sliding groove. The internal threaded slider 12 is slidably disposed in the slide groove. A second servo motor 22 is fixedly disposed on the left side of the base 1. The output end of the second servo motor 22 passes through the slide groove and is connected to the bidirectional lead screw 23. A first support sleeve 11 is sleeved on the outer wall of the bidirectional lead screw 23. The first support sleeve 11 is fixedly disposed in the slide groove and supports the rotation of the bidirectional lead screw 23. A second support sleeve 18 is sleeved on the outer wall of the connecting shaft 19. The second support sleeve 18 is fixedly disposed on the top of the base 1 and supports the rotation and sliding of the connecting shaft 19.
[0016] Working principle: The hydraulic pipe clamping machine 15 clamps and fixes the steel pipe 17. The second servo motor 22 drives the bidirectional lead screw 23 to rotate, which in turn drives the two sets of internal threaded sliders 12 to move inward synchronously. This, in turn, drives the L-plate 14 and the hydraulic pipe clamping machine 15 to move inward synchronously through the connecting plate 13, which in turn drives the polishing wheel 2 and the steel pipe 17 to move inward synchronously. This allows the polishing wheel 2 to move inside the steel pipe 17. At the same time, the first servo motor 21 drives the connecting shaft 19 to rotate, which in turn drives the polishing wheel 2 to rotate. When the polishing wheel 2 is inserted into the steel pipe 17, the rotating polishing wheel 2 can polish the inner surface of the steel pipe 17. By moving the polishing wheel 2 and the steel pipe 17 relative to each other, the required travel distance of the polishing wheel 2 can be greatly shortened, thereby greatly shortening the overall length of the entire device.
[0017] After polishing is completed, the second servo motor 22 drives the bidirectional lead screw 23 to reverse, thereby driving the polishing wheel 2 and the steel pipe 17 to move outward synchronously. This allows the polishing wheel 2 to quickly exit from the steel pipe 17, thereby improving the processing efficiency of the steel pipe 17. By installing the bidirectional lead screw 23 inside the base 1, it is possible to effectively prevent the polishing debris from contacting the bidirectional lead screw 23 and affecting its normal operation, thereby improving the reliability of the device.
