Description

Technical Field

[0001] This utility model relates to a positioning device for steel pipe processing, specifically a positioning device for seamless steel pipe processing. Background Technology

[0002] In the production and processing of existing seamless steel pipes, positioning, or clamping, is generally required to prevent shaking, errors, and impact on processing quality. However, the distance between the structures used for clamping in existing positioning devices is fixed and cannot be changed. This results in the pipe's suspended length being fixed and cannot be altered. Consequently, when punching, if the suspended length of the pipe is too long, it will cause the pipe to bend. When grinding, if the suspended length of the pipe is too short, multiple clamping operations are required.

[0003] For example, a positioning device for seamless steel pipe processing disclosed in Chinese Patent Publication No. CN113894202A reduces or increases the length of the suspended part of the pipe by pushing the sliding clamp group closer to or away from the fixed clamp group, thereby changing the length of the suspended part of the pipe. This solves the problem that the length of the suspended part of the pipe is fixed and cannot be changed in existing devices. That is, when the sliding clamp group is rotated to perform the clamping action, the double-sided toothed belt drive synchronously drives the fixed clamp group to perform the clamping action, thereby reducing the operator's operating intensity and improving the operating efficiency of the device.

[0004] The existing technology has the following problems:

[0005] However, while the above-mentioned device reduces the operator's workload by clamping the toothed belt during the actual clamping process, the three-jaw chuck is difficult to stop urgently during the clamping process, and the clamping stability needs to be improved, as the stability is not high. Utility Model Content

[0006] This utility model provides a positioning device for seamless steel pipe processing to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A positioning device for processing seamless steel pipes includes a processing base. A clamping device is mounted on the processing base. The clamping device includes a steel pipe clamping unit, a multi-angle processing unit, and a stopping unit. The steel pipe clamping unit is mounted on the processing base. The multi-angle processing unit is fixedly mounted on the steel pipe clamping unit. The stopping unit is slidably connected to the multi-angle processing unit. The steel pipe clamping unit includes a limiting slide block, which is fixedly mounted on the processing base. A sliding groove is formed within the limiting slide block. A sliding connecting block is provided within the sliding groove. A through groove is provided within the through groove. A bidirectional screw is provided within the through groove.

[0009] A further improvement of this utility model is that: the sliding connecting block is slidably connected to the limiting slide block through the sliding groove, the inner wall of the sliding connecting block through the groove is provided with a threaded groove, the bidirectional screw is threadedly connected to the sliding connecting block, and a handle is fixedly installed at the end of the bidirectional screw away from the limiting slide block. By rotating the bidirectional screw through the handle, because the inner wall of the sliding connecting block through the groove is provided with a threaded groove, the sliding connecting block begins to slide in the sliding groove of the limiting slide block while the bidirectional screw is rotating.

[0010] A further improvement of this utility model is that: the sliding connecting blocks are in two sets, and a buffer layer is provided between the two sliding connecting blocks. The buffer layer is fixedly installed in the limiting slide seat, and a telescopic rod is fixedly installed on the top of the buffer layer. A placement base is fixedly installed on the top of the telescopic rod, and the steel pipe is placed on the placement base. By utilizing the telescopic characteristics of the telescopic rod, the height of the steel pipe and the steel pipe clamping unit on the sliding connecting block is changed, so that steel pipes of different thicknesses and models can be clamped. In addition, the buffer layer also ensures that the two sliding connecting blocks do not collide or squeeze during sliding.

[0011] A further improvement of this utility model is that, in order to ensure that the two sliding connecting blocks can move toward each other when the bidirectional screw rotates, thereby achieving clamping capability, the bidirectional screw is provided with a positive thread at the connection point with one of the sliding connecting blocks, and the bidirectional screw is provided with a reverse thread at the connection point with the other sliding connecting block.

[0012] A further improvement of the present invention is that: a connecting block is fixedly installed on the top of the two sliding connecting blocks, and a chuck is provided at one end of each of the two connecting blocks that is close to each other. In order to avoid damage to the steel pipe during the clamping process due to the chuck being too hard, a rubber pad is fixedly installed at one end of the chuck.

[0013] A further improvement of the present invention is that the multi-angle processing unit includes a connecting column, the connecting column is located in the mounting hole of the connecting block, the connecting column is rotatably connected to the connecting block, the connecting column is fixedly connected to the chuck, and a limit plate is fixedly installed at the other end of the connecting column, the limit plate is slidably connected to the braking unit.

[0014] A further improvement of this utility model is that: the stopping unit includes a gasket, which is fixedly installed on the sliding connecting block by fasteners. One end of the gasket is fixedly connected to a connecting block, and a stopping shaft is rotatably connected inside the connecting block. A stopping block is fixedly installed on the stopping shaft. The limiting plate has one or more slots, and the stopping block is slidably connected to the slot. A rotating component is fixedly installed on one end of the stopping shaft. By rotating the rotating component, the stopping shaft rotates, and the stopping block on the stopping shaft begins to perform circular motion. When the stopping block is located at the slot on the limiting plate, the limiting plate cannot rotate, thereby preventing the limiting plate from driving the connecting column to rotate.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] This utility model provides a positioning device for seamless steel pipe processing. Through the steel pipe clamping unit and the multi-angle processing unit, the steel pipe can be clamped while other surfaces of the steel pipe need to be processed. The steel pipe can rotate while being clamped, and no vibration is generated during the rotation process. This ensures that the steel pipe does not shake or shift during processing, thus guaranteeing successful processing.

[0017] This utility model provides a positioning device for seamless steel pipe processing. The stopping unit enables the circuit to limit the multi-angle processing unit during the processing, preventing the steel pipe from rotating and shifting to a certain extent due to the influence of impact and friction during processing, ensuring the clamping degree of the steel pipe and improving the practicality of the overall device.

[0023] Please see Figures 1-4 This utility model provides a technical solution: Example 1

[0024] A positioning device for seamless steel pipe processing includes a processing base 1. A clamping device is provided on the processing base 1, comprising a steel pipe clamping unit, a multi-angle processing unit, and a stopping unit. The steel pipe clamping unit is mounted on the processing base 1, and the multi-angle processing unit is fixedly mounted on the steel pipe clamping unit. The stopping unit is slidably connected to the multi-angle processing unit. The steel pipe clamping unit includes a limiting slide 201, which is fixedly mounted on the processing base 1. A sliding groove is formed within the limiting slide 201, and a sliding connecting block 202 is provided within the sliding groove. A through groove is provided within the through groove, and a bidirectional screw 203 is provided within the through groove. The sliding connecting block 202 is slidably connected to the limiting slide 201 through the sliding groove. A threaded groove is provided on the inner wall of the through groove of the sliding connecting block 202, and the bidirectional screw 203 is threadedly connected to the sliding connecting block 202. A handle 204 is fixedly installed at the end of the bidirectional screw 203 away from the limiting slide 201. In this invention, the bidirectional screw 203 is rotated by the handshake 204. Because the inner wall of the sliding connecting block 202 through groove is provided with a threaded groove, the sliding connecting block 202 begins to slide in the sliding groove of the limiting slide block 201 while the bidirectional screw 203 is rotating.

[0025] There are two sets of sliding connecting blocks 202, and a buffer layer 205 is provided between the two sliding connecting blocks 202. The buffer layer 205 is fixedly installed in the limiting slide 201. A telescopic rod 206 is fixedly installed on the top of the buffer layer 205, and a placement base 207 is fixedly installed on the top of the telescopic rod 206. The steel pipe is placed on the placement base 207. Through the telescopic characteristics of the telescopic rod 206, the height of the steel pipe and the steel pipe clamping unit on the sliding connecting block 202 is changed, so that steel pipes of different thicknesses and models can be clamped. The buffer layer 205 also ensures that the two sliding connecting blocks 202 do not collide or squeeze each other during sliding.

[0026] To ensure that the two sliding connecting blocks 202 can move towards each other when the bidirectional screw 203 rotates, thereby achieving clamping capability, the bidirectional screw 203 is provided with a positive thread at the connection point with one of the sliding connecting blocks 202, and the bidirectional screw 203 is provided with a reverse thread at the connection point with the other sliding connecting block 202. Example 2

[0027] Based on Example 1:

[0028] Two sliding connecting blocks 202 are fixedly installed with connecting blocks 208 on their tops. Each of the two connecting blocks 208 is provided with a chuck 209 at one end close to the other. In order to prevent the chuck 209 from being too hard and causing damage to the steel pipe during the clamping process, a rubber pad 210 is fixedly installed at one end of the chuck 209. Example 3

[0029] Based on Example 1:

[0030] The multi-angle machining unit includes a connecting column 301, which is located in the mounting hole of the connecting block 208. The connecting column 301 is rotatably connected to the connecting block 208 and is fixedly connected to the chuck 209. A limit plate 302 is fixedly installed at the other end of the connecting column 301 and is slidably connected to the braking unit.

[0031] The braking unit includes a gasket 401, which is fixedly mounted on the sliding connecting block 202 by fasteners. One end of the gasket 401 is fixedly connected to a connecting block 402, and a stop shaft 403 is rotatably connected inside the connecting block 402. A stop block 404 is fixedly mounted on the stop shaft 403. The limiting plate 302 has one or more slots 405. The stop block 404 is slidably connected to the slot 405. One end of the stop shaft 403 is fixedly mounted with a rotating component 406. The stop shaft 403 rotates by rotating the rotating component 406, and the stop block 404 on the stop shaft 403 begins to perform circular motion. When the stop block 404 is located at the slot 405 on the limiting plate 302, the limiting plate 302 cannot rotate, thereby preventing the limiting plate 302 from driving the connecting column 301 to rotate.

[0032] This device uses a steel pipe placed on a base 207. The telescopic rod 206 changes the height of the steel pipe clamping unit on the sliding connecting block 202, allowing steel pipes of different thicknesses and models to be clamped. The buffer layer 205 ensures that the two sliding connecting blocks 202 do not collide or squeeze during sliding. The bidirectional screw 203 is rotated via the handle 204. Because the inner wall of the sliding connecting block 202 has a threaded groove, the sliding connecting block 202 begins to slide in the sliding groove within the limiting slide block 201 as the bidirectional screw 203 rotates. This is because the bidirectional screw 203 has forward and reverse threads. When the bidirectional screw 203 rotates, the two sliding connecting blocks 202 can move towards each other to achieve clamping capability. When the steel pipe is clamped and other surfaces need to be ground, the limiting plate 302 is rotated, causing the connecting column 301 to rotate. Then, the chuck 209 drives the steel pipe to rotate. When the steel pipe does not need to rotate or move during processing, the rotating part 406 rotates, causing the stop shaft 403 to rotate. The stop block 404 on the stop shaft 403 starts to make a circular motion. When the stop block 404 is located at the insertion port 405 on the limiting plate 302, the limiting plate 302 cannot rotate, thus preventing the limiting plate 302 from driving the connecting column 301 to rotate.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
