Description

Technical Field

[0001] The utility model relates to the technical field of steel processing, in particular to a steel processing positioning base. Background Art

[0002] Steel pipe is a kind of steel with a hollow section, whose length is much larger than its diameter or circumference. Steel pipe is not only used to transport fluids and powdered solids, exchange heat energy, manufacture mechanical parts and containers, but it is also an economical steel.

[0003] The utility model with authorization announcement number CN218169507U provides a positioning tool for steel pipe processing, which can position the steel pipe by clamping it with two arc-shaped clamping plates when grinding or cutting, so as to keep it stable and facilitate the grinding or cutting process respectively.

[0004] However, in the above patent, the two arc-shaped clamps can only clamp and fix a steel pipe of a certain specific diameter with the inner arc surface of the arc-shaped clamps completely in contact with the wall of the steel pipe. When the two arc-shaped clamps clamp and fix a steel pipe with a larger or smaller diameter, the contact area between the arc-shaped clamps and the outer wall of the steel pipe becomes smaller, resulting in reduced clamping stability. At the same time, after the two arc-shaped clamps clamp and fix the steel pipe, the steel pipe cannot be rotated freely to adjust the processing position of the outer wall of the steel pipe. In view of this, we propose a steel processing positioning base. Summary of the invention

[0005] The purpose of the utility model is to provide a steel processing positioning base to solve the problems raised in the above background technology.

When clamping and fixing steel pipes of different diameters, the contact area between the clamping blocks and the steel pipe remains unchanged, so the clamping stability remains unchanged, and steel pipes of different diameters can be stably clamped. In addition, the steel pipe can be freely rotated by utilizing the lower rolling friction between the steel pipe and the roller, so that different positions of the steel pipe wall can be processed conveniently.

Example

[0026] See also Figure 1-Figure 4As shown, the present embodiment provides a steel processing positioning base, including a hollow table 1, a movable frame 2 is symmetrically and slidably connected to the top of the hollow table 1, a distance adjusting mechanism 4 is provided between the two movable frames 2, and a clamping mechanism 3 is provided above the movable frame 2. The distance adjusting mechanism 4 can drive the two movable frames 2 to move horizontally synchronously, and adjust the distance between the two clamping mechanisms 3. By sleeve-arranging the two clamping mechanisms 3 on the outer side of the steel pipe wall, the two clamping mechanisms 3 can clamp and fix steel pipes of different lengths. The clamping mechanism 3 includes an assembly frame 31 fixedly connected to the upper surface of the movable frame 2, a circular groove is provided on the side wall of the assembly frame 31, and a rotating frame 32 is rotatably connected to the inner wall of the circular groove. A plurality of clamping blocks 33 are rotatably connected to a circular array on one side of the assembly frame 31, and a sliding sleeve 34 is slidably sleeved on the outer wall of the clamping block 33, and the sliding sleeve 34 is rotatably connected to the inner wall of the rotating frame 32. One end of the clamping block 33 located in the rotating frame 32 rotates The rotating frame 32 is connected with a roller 35. The rotating frame 32 is a cylindrical structure with hollowed-out side walls. The circular groove is connected to the interior of the rotating frame 32. The steel pipe to be processed is passed through the circular groove and the interior of the rotating frame 32 to rotate the rotating frame 32. The rotating frame 32 drives the clamping block 33 to rotate through the sliding sleeve 34. During this process, the sliding sleeve 34 slides along the outer wall of the clamping block 33 until the clamping block 33 drives the roller 35 to rotate to a position against the outer wall of the steel pipe, and then the horizontal and vertical movement of the steel pipe is restricted by a plurality of rollers 35. After the steel pipe is clamped and fixed, the steel pipe can be freely rotated by utilizing the lower rolling friction between the steel pipe and the roller 35, so as to facilitate the adjustment of the processing position of the steel pipe wall. A linkage assembly 36 is provided on one side of the two rotating frames 32. The linkage assembly 36 is used to drive the two rotating frames 32 to rotate synchronously, so that after the steel pipe passes through the two rotating frames 32, the two sets of rollers 35 can quickly clamp and fix the steel pipe.

[0027] In order to enable the two groups of rollers 35 in the two rotating frames 32 to synchronously clamp and fix the steel pipe after the steel pipe is placed inside the two rotating frames 32, a linkage assembly 36 is set on the outside of the two rotating frames 32, so that workers can synchronously rotate the two rotating frames 32, and the structure of the linkage assembly 36 is refined. The two linkage assemblies 36 include an extension rod 361 fixedly connected to the outer wall of the circumference of the rotating frame 32, a sleeve 362 is slidably sleeved on the outer side of the extension rod 361, a square tube 363 is rotatably connected to one side of the sleeve 362, and a lifting rod 365 is slidably connected to the inner walls of the two square tubes 363. The linkage assembly 36 also includes a threaded rod 364 rotatably connected to the top of the hollow table 1, the lifting rod 365 is threadedly connected to the outer wall of the circumference of the threaded rod 364, and a rotating rod 366 is rotatably connected to one side of the hollow table 1. The rotating rod 366 and the threaded rod 364 are located inside the hollow table 1 One end is fixedly connected with a bevel gear 367, and the two bevel gears 367 are meshed with each other. When the rotating rod 366 is turned to drive one of the bevel gears 367 to rotate, the other bevel gear 367 drives the threaded rod 364 to rotate, and then the lifting rod 365 drives the two square tubes 363 to move vertically upward. The square tube 363 drives the extension rod 361 to flip through the sleeve 362. In the process of the extension rod 361 driving the rotating frame 32 to rotate, the sleeve 362 slides along the outer wall of the extension rod 361 to achieve the purpose of synchronously rotating the two rotating frames 32. When the movable frame 2 moves horizontally, the square tube 363 slides along the outer wall of the lifting rod 365. In the horizontal movement range of the movable frame 2, the square tube 363 will not be out of contact with the lifting rod 365, and then after adjusting the spacing between the two clamping mechanisms 3, the two rotating frames 32 can still be rotated synchronously through the linkage assembly 36.

[0028] In order to adjust the spacing between the two clamping mechanisms 3 so that the two clamping mechanisms 3 can clamp and fix steel pipes of different lengths, a spacing adjustment mechanism 4 is arranged between the two movable frames 2, and the structure of the spacing adjustment mechanism 4 is refined. The spacing adjustment mechanism 4 includes a screw rod 41 rotatably connected to the side wall of the hollow table 1, and the circumferential outer wall of the screw rod 41 is provided with a positive thread and a negative thread, and the circumferential outer walls of the positive thread and the negative thread are threadedly connected with nuts 42, and the two movable frames 2 are respectively fixedly connected to the tops of the two nuts 42, and two movable grooves 43 are provided on the top of the hollow table 1. The two movable frames 2 are slidingly connected to the inner walls of the two movable grooves 43. The screw rod 41 is turned so that the two nuts 42 respectively drive the two movable frames 2 to move horizontally along the inner walls of the movable grooves 43, and the two movable frames 2 respectively drive the two clamping mechanisms 3 to move toward or away from the threaded rod 364, thereby adjusting the spacing between the two clamping mechanisms 3, so that the two rotating frames 32 can be sleeved on the outer sides of the pipe walls of steel pipes of different lengths.

[0029] In summary, the working principle of the present scheme is as follows: the screw rod 41 is turned to make the two movable frames 2 move horizontally synchronously in a direction away from or close to the threaded rod 364. After adjusting the spacing between the two assembly frames 31, the steel pipe to be processed is passed through the inside of the two rotating frames 32, so that the two rotating frames 32 are both sleeved on the outside of the steel pipe wall, and then the rotating rod 366 is turned to make the lifting rod 365 drive the square pipe 363 to move upward synchronously, so that the two rotating frames 32 rotate synchronously, and the clamping block 33 drives the roller 35 to flip to a position against the steel pipe wall, and then the horizontal and vertical movement of the steel pipe is limited by a plurality of rollers 35, and the steel pipe is clamped and fixed, and then the lower rolling friction between the steel pipe and the roller 35 is utilized to freely rotate the steel pipe, so as to facilitate the processing of different positions of the steel pipe wall.
