Description

Technical Field

[0001] The utility model relates to the technical field of polishing devices, and more specifically, the utility model relates to a polishing device for the inner and outer surfaces of steel pipes. Background Art

[0002] Polishing refers to the treatment of the surface roughness of metal raw materials using polishing tools. Commonly used polishing tools include polishing rods, polishing powders, sandpapers, etc., in order to obtain metal raw materials with smooth surfaces. After the production of some parts is completed, due to reasons such as process technology, the surface of the parts is not smooth enough, which affects the assembly or use of subsequent parts. Generally, polishing treatment is carried out on materials when high requirements are placed on the surface quality of the materials. The polishing of the inner and outer walls of steel pipes is one type of polishing treatment. The traditional operation method for polishing the inner and outer walls of steel pipes is to first place the steel pipe on an outer wall polishing device, drive the steel pipe to rotate using power equipment such as motors, and use fixed polishing tools to polish the outer wall of the steel pipe. Then, an inner wall polishing tool is used to polish the inner wall of the steel pipe. Although this treatment method can polish both the inner and outer walls of the steel pipe, since the inner and outer surfaces of the steel pipe need to be polished separately and two sets of equipment are required during the polishing process, the workload of the entire working process is large and the production efficiency is low. In order to solve the deficiencies of the prior art, we propose a polishing device for the inner and outer surfaces of steel pipes. Summary of the Utility Model

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a polishing device for the inner and outer surfaces of steel pipes to solve the problems of large workload and low production efficiency in the entire working process.

[0004] To solve the above technical problems, the utility model provides the following technical solution: A polishing device for the inner and outer surfaces of steel pipes, including a base body, wherein a polishing assembly is arranged on the outer surface of the upper side of the base body, and a transportation assembly is arranged on one side of the polishing assembly;

[0005] The polishing assembly includes a motor frame, on one side outer surface of which a roller motor is fixedly installed. On one outer wall of the rotating shaft of the roller motor, a large gear is fixedly sleeved. On one outer surface of the rotating shaft of the large gear, a gear frame is rotatably connected. Two small gears are meshed with the outer edge of the large gear. On the inner walls of the two small gears, a rolling shaft is fixedly sleeved. On the outer surfaces of both sides of the rolling shaft, two roller frames are rotatably connected. Above the rolling shaft, there is a large bracket. On the upper side outer surface of the large bracket, a fixing plate is detachably installed. Inside the fixing plate, a movable bolt is slidably connected. On one outer surface of the movable bolt, a polishing block is threadedly connected. A spring is movably sleeved on the outer wall of the movable bolt. On one side of the rolling shaft, there is a heightening bracket. On the upper side outer surface of the heightening bracket, a cylinder is fixedly installed. At one end outer surface of the piston rod of the cylinder, a T-shaped slider is fixedly connected. Inside the T-shaped slider, an inner polishing motor is fixedly installed. On one outer wall of the rotating shaft of the inner polishing motor, a thousand-leaf wheel is fixedly sleeved.

[0006] Among them, the motor frame is fixedly installed on the upper side edge outer surface of the base body. The roller frame is fixedly installed on the upper side middle outer surface of the base body. The large bracket is fixedly installed on the upper side outer surface of the base body on one side of the motor frame. The T-shaped slider is slidably connected to the inner wall of the bottom of the large bracket.

[0007] Among them, the conveying assembly includes a feeding frame. On one side outer surfaces of the two feeding frames, a feeding motor is fixedly installed. On one outer surface of the rotating shaft of the feeding motor, a crank is fixedly installed. On one outer surface of the crank, a connecting rod is rotatably connected. On one outer surface of the connecting rod, a cylindrical slider is rotatably connected. The outer wall of the cylindrical slider is slidably connected to a loading machine. On the upper side outer surface of the loading machine, a feeding port is opened. On one outer surface of the loading machine, an outlet is opened. On one side of the loading machine, there is an inclined rail. On one outer surface of the inclined rail, a material box is welded.

[0008] Among them, the feeding frame is fixedly installed on the upper side outer surface of the base body. The loading machine is fixedly installed on the upper side outer surface of the base body on one side of the feeding frame. The inclined rail is welded on one outer surface of the base body. The material box is welded on one outer surface of the base body on one side of the inclined rail.

[0009] Among them, the cross-sectional diameter of one side of the rolling shaft is smaller than that of the other side. At one side edge of the bottom of the polishing block, a fillet is provided.

[0010] Among them, the inclined rail is directly below the side with the smaller cross-sectional diameter of the rolling shaft.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] The utility model realizes the simultaneous polishing of the inner and outer surfaces of a steel pipe by setting a polishing assembly, which includes a motor frame. A roller motor drives a rolling shaft to rotate, and the steel pipe will rotate with the rolling shaft. At this time, a polishing block will polish the outer wall of the steel pipe. Since an inner polishing motor is fixedly installed on the inner wall of a T-shaped slider, and a thousand-leaf wheel is fixedly sleeved on the outer wall of one end of the rotating shaft of the inner polishing motor, the thousand-leaf wheel will polish the inner wall of the steel pipe at this time. By using the above structure, the steel pipe is polished by the polishing block and the thousand-leaf wheel, reducing the workload of the whole working process and improving the production efficiency.

[0013] The utility model realizes the automatic polishing of the steel pipe and the automatic loading of the steel pipe into a material box by setting a conveying assembly, which includes a feeding frame. Multiple steel pipes are put into the feeding port. At this time, under the action of a feeding motor, a cylindrical slider will periodically push the steel pipe onto the rolling shaft. The latter steel pipe will push the former steel pipe under the polishing block. After polishing, since one end of the piston rod of a cylinder is fixedly connected to a T-shaped slider, and the T-shaped slider is slidably connected to the inner wall of the bottom of a large bracket, the piston rod of the cylinder will drive the T-shaped slider to retract. Since the cross-sectional diameter of one end of the rolling shaft is smaller than the rest, the latter steel pipe will push the former steel pipe into this section at this time, and the steel pipe will fall into an inclined rail through the gap between the two rolling shafts and finally into a material box. By using the above structure, the steel pipe is periodically pushed by the cylindrical slider, realizing the automatic polishing of the steel pipe and the automatic loading of the steel pipe into the material box. Only by putting in the steel pipe on time can the whole polishing operation be completed, improving the practicability of the device. Description of the Drawings

[0023] As shown in the attached Figure 1 to the attached Figure 6 An embodiment of the present utility model provides a polishing device for the inner and outer surfaces of steel pipes, including a base body 1. A polishing assembly 2 is arranged on the outer surface of the upper side of the base body 1, and a conveying assembly 3 is arranged on one side of the polishing assembly 2;

[0024] The polishing assembly 2 includes a motor frame 21. A roller motor 22 is fixedly installed on the outer surface of one side of the motor frame 21.

A gear frame 24 is rotatably connected to the outer surface of one side of the rotating shaft of the large gear 23. Two small gears 25 are meshed with the outer edge of the large gear 23. Two rolling shafts 26 are fixedly sleeved on the inner walls of the two small gears 25. Two roller frames 27 are rotatably connected to the outer surfaces of both sides of the rolling shaft 26. A large bracket 28 is arranged on the upper side of the rolling shaft 26. A fixed plate 29 is detachably installed on the outer surface of the upper side of the large bracket 28. A movable bolt 210 is slidably connected to the inner wall of the fixed plate 29. A polishing block 211 is threadedly connected to the outer surface of one side of the movable bolt 210. A spring 212 is movably sleeved on the outer wall of the movable bolt 210. A raising frame 213 is arranged on one side of the rolling shaft 26. A cylinder 214 is fixedly installed on the outer surface of the upper side of the raising frame 213. One end of the piston rod of the cylinder 214 is fixedly connected to a T-shaped slider 215. An inner polishing motor 216 is fixedly installed on the inner wall of the T-shaped slider 215. A thousand-leaf wheel 217 is fixedly sleeved on the outer wall of one end of the rotating shaft of the inner polishing motor 216.

[0025] Among them, the motor frame 21 is fixedly installed on the outer surface of the upper side edge of the base body 1, the roller frame 27 is fixedly installed on the outer surface of the middle of the upper side of the base body 1, the large bracket 28 is fixedly installed on the outer surface of the upper side of the base body 1 on one side of the motor frame 21, and the T-shaped slider 215 is slidably connected to the inner wall of the bottom of the large bracket 28;

[0026] The large gear 23 is driven to rotate by the roller motor 22. Since the outer edge of the large gear 23 meshes with the small gear 25, and the inner wall of the small gear 25 is fixedly sleeved with the rolling shaft 26, at this time the rolling shaft 26 will drive the steel pipe to rotate. Since the inner wall of the fixing plate 29 is slidably connected with the movable bolt 210, the outer surface of one side of the movable bolt 210 is threadedly connected with the polishing block 211, and the outer wall of the movable bolt 210 is movably sleeved with the spring 212. At this time, the polishing block 211 will polish the outer wall of the steel pipe. Since the thousand-leaf wheel 217 is fixedly sleeved on the outer wall of one end of the rotating shaft of the inner polishing motor 216, at this time the thousand-leaf wheel 217 polishes the inner wall of the steel pipe.

[0027] Among them, the conveying component 3 includes a feeding frame 31. On the outer surface of one side of the two feeding frames 31, a feeding motor 32 is fixedly installed. On the outer surface of one end of the rotating shaft of the feeding motor 32, a crank 33 is fixedly installed. On the outer surface of one side of the crank 33, a connecting rod 34 is rotatably connected. On the outer surface of one side of the connecting rod 34, a cylindrical slider 35 is rotatably connected. The outer wall of the cylindrical slider 35 is slidably connected with a loading machine 36. On the upper side outer surface of the loading machine 36, a feeding port 37 is opened. On the outer surface of one side of the loading machine 36, an outlet 38 is opened. On one side of the loading machine 36, an inclined rail 39 is arranged. On the outer surface of one side of the inclined rail 39, a material box 310 is welded;

[0028] The crank 33 is driven to rotate by the feeding motor 32, and at the same time the connecting rod 34 is driven to rotate together. The cylindrical slider 35 will perform periodic reciprocating motion inside the loading machine 36. Since the feeding port 37 is opened on the upper side outer surface of the loading machine 36, the steel pipe will be periodically pushed onto the rolling shaft 26 by the cylindrical slider 35. The polished steel pipe will be pushed into the inclined rail 39 by the next steel pipe to be polished, and finally fall into the material box 310.

[0029] Among them, the feeding frame 31 is fixedly installed on the outer surface of the upper side of the base body 1, the loading machine 36 is fixedly installed on the outer surface of the upper side of the base body 1 on one side of the feeding frame 31, the inclined rail 39 is welded on the outer surface of one side of the base body 1, and the material box 310 is welded on the outer surface of one side of the base body 1 on one side of the inclined rail 39.

[0030] Among them, the cross-sectional diameter of one side of the rolling shaft 26 is smaller than that of the other side, and a fillet is arranged at the bottom edge of one side of the polishing block 211;

[0031] A rounded corner is provided at the bottom side edge of the polishing block 211, so that the steel pipe will not be blocked when it is pushed under the polishing block 211. Since the cross-sectional diameter of one end of the rolling shaft 26 is smaller than that of the other side, when the steel pipe is pushed into this section, it will fall into the inclined rail 39 through the gap between the two rolling shafts 26.

[0032] Among them, the inclined rail 39 is directly below the side with a smaller cross-sectional diameter of the rolling shaft 26.

[0033] The working process of the utility model is as follows:

[0034] First, multiple steel pipes are placed from the feed port 37. At this time, under the action of the feeding motor 32, the cylindrical slider 35 will periodically push the steel pipes onto the rolling shaft 26. The latter steel pipe will push the former steel pipe under the polishing block 211. Since the roller motor 22 will drive the rolling shaft 26 to rotate, the steel pipe will rotate with the rolling shaft 26. At this time, the polishing block 211 will polish the outer wall of the steel pipe. Since the inner wall of the T-shaped slider 215 is fixedly installed with an inner polishing motor 216, and one end of the rotating shaft of the inner polishing motor 216 is fixedly sleeved with a thousand-leaf wheel 217, at this time, the thousand-leaf wheel 217 will polish the inner wall of the steel pipe. After the polishing is completed, since one end of the piston rod of the air cylinder 214 is fixedly connected to the T-shaped slider 215, and the T-shaped slider 215 is slidably connected to the bottom inner wall of the large bracket 28, the piston rod of the air cylinder 214 will drive the T-shaped slider 215 to retract. Since the cross-sectional diameter of one end of the rolling shaft 26 is smaller than that of the other side, at this time, the latter steel pipe will push the former steel pipe into this section, and at this time, the steel pipe will fall into the inclined rail 39 through the gap between the two rolling shafts 26, and finally the steel pipe will fall into the material frame 310.
