Auxiliary positioning device

Abstract

According to the auxiliary positioning device provided by the embodiment of the invention, the to-be-welded pipe type steel structural part penetrates through the positioning hole and is placed on the supporting base, and the supporting base can be forced to move downwards by the gravity of the steel structural part. Due to the fact that the supporting base is connected with the auxiliary clamping block through the steel wire rope, the auxiliary clamping block can move in the direction close to the steel structural part until the auxiliary clamping block abuts against the steel structural part. And then the telescopic air cylinder is controlled to fix the steel structural part between the first clamping block and the second clamping block, so that follow-up welding treatment is facilitated. When the steel structural part needs to be rotated, the second clamping block is moved in the opposite direction firstly, then the steel structural part is rotated in the positioning hole until the steel structural part reaches the preset welding position, and then the telescopic air cylinder is controlled to fix the steel structural part again through the second clamping block. By the adoption of the structural design, the steel structural part can rotate in the positioning hole by directly controlling the telescopic air cylinder to move, so that the rotating procedure of the steel structural part is simplified, and the overall welding efficiency is improved.

[0002] Welding is a process of melting the surfaces to be welded of two metals by the combustion of an acetylene flame, and then bringing the two melted surfaces into contact and cooling and hardening them to fix them together. Ordinary welding can be completed with a welding torch, and the user can directly weld the metal parts by holding the welding torch. For metal parts with larger specifications or certain requirements for the welding surface, an auxiliary positioning device is required to fix or move the metal parts to achieve the desired welding effect.

[0003] In the related art, seamless welding is generally required for the ends of steel structure parts such as pipes. Therefore, during actual operation, the steel structure parts are rotated while welding. However, the traditional auxiliary positioning device does not have a separate rotation function when fixing steel structure parts such as pipes. Therefore, each time it is rotated, the steel structure parts need to be loosened and then rotated to the welding position, which greatly reduces the welding efficiency. Summary of the Utility Model

[0004] In view of this, the embodiments of this application provide an auxiliary positioning device to solve the problem that the traditional auxiliary positioning device in the related art does not have a separate rotation function for steel structure parts such as pipes, resulting in low welding efficiency.

Specific embodiments

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] As Figures 1 - 3 shown, the auxiliary positioning device provided by the embodiment of the present application includes a workbench 100, a first clamping block 200, a telescopic cylinder 300, a second clamping block 400, an auxiliary clamping block 500, and a support base 700. Among them, steel structure parts in the shape of steel pipes are welded on the upper surface of the workbench 100. Support legs 110 are fixedly arranged on the lower surface of the workbench 100, and the workbench 100 is erected at a designated position on the ground through the support legs 110. A positioning hole 120 is also formed in the workbench 100 along the thickness direction, and the positioning hole 120 is a circular hole. During actual use, the steel structure parts in the shape of steel pipes to be welded can be inserted into the positioning hole 120 to determine their positions.

[0028] The upper surface of the workbench 100 is fixedly provided with a first clamping block 200. Specifically, the first clamping block 200 is located beside the positioning hole 120, and a first arc surface 210 is provided at the wall surface of the first clamping block 200 close to the positioning hole 120. The upper surface of the workbench 100 is also fixedly provided with a telescopic cylinder 300, and the telescopic cylinder 300 is located on the opposite side of the first clamping block 200. Moreover, a second clamping block 400 is fixedly provided at the driving end of the telescopic cylinder 300, and the second clamping block 400 is located beside the positioning hole 120. The second clamping block 400 can move along with the driving end of the telescopic cylinder 300 to clamp and fix the steel structure parts in the shape of a steel pipe located inside the positioning hole 120. In addition, a second arc surface 410 is provided at the wall surface of the second clamping block 400 close to the positioning hole 120.

[0029] In this embodiment, two auxiliary clamping blocks 500 are also slidably provided on the upper surface of the workbench 100. The two auxiliary clamping blocks 500 are located beside the positioning hole 120, and the connection line between the two auxiliary clamping blocks 500 is perpendicular to the connection line between the first clamping block 200 and the second clamping block 400. The two auxiliary clamping blocks 500 can approach or move away from each other. When the two auxiliary clamping blocks 500 approach each other, they can act on the steel structure parts in the shape of a steel pipe located inside the positioning hole 120 to achieve the purpose of secondary clamping and fixing.

[0030] A support base 700 is also provided below the workbench 100. Specifically, the support base 700 is located directly below the positioning hole 120, and the center of the support base 700 coincides with the center of the positioning hole 120. The support base 700 is connected to the two auxiliary clamping blocks 500 through a steel wire rope 600. Therefore, when the steel structure parts in the shape of a steel pipe pass through the positioning hole 120 and are placed on the support base 700, the support base 700 will move downward and pull the two clamping blocks to move towards the direction close to the positioning hole 120 through the steel wire rope 600 to achieve the function of clamping the steel structure parts in the shape of a steel pipe.

[0031] In the auxiliary positioning device provided in the embodiments of the present application, the steel pipe structure to be welded is passed through the positioning hole 120 and placed on the support base 700. The gravity of the steel structure itself will force the support base 700 to move downward. Since the support base 700 is connected to the auxiliary clamping block 500 through the steel wire rope 600, the auxiliary clamping block 500 will move towards the direction close to the steel structure until it abuts against it. Then, the telescopic cylinder 300 is controlled to fix the steel structure between the first clamping block 200 and the second clamping block 400, so as to facilitate subsequent welding treatment. When it is necessary to rotate the steel structure, first move the second clamping block 400 in the opposite direction, then rotate the steel structure in the positioning hole 120 until the preset welding position, and then control the telescopic cylinder 300 to fix the steel structure again through the second clamping block 400. With the above structural design, the steel structure can be directly rotated in the positioning hole 120 by controlling the movement of the telescopic cylinder 300, thereby simplifying the rotation process of the steel structure and improving the overall welding efficiency.

[0032] In some embodiments, a T-shaped sliding portion 510 is provided at the bottom end of the auxiliary clamping block 500, and a T-shaped sliding groove 130 is provided on the upper surface of the workbench 100. The auxiliary clamping block 500 is slidably arranged in the T-shaped sliding groove 130 of the workbench 100 through the T-shaped sliding portion 510. In addition, a spring 800 is also provided in the T-shaped sliding groove 130, and the spring 800 is fixedly connected to the T-shaped sliding portion 510 and the groove wall of the T-shaped sliding groove 130 respectively. When the steel pipe structure disengages from the support base 700, under the action of the spring 800, the auxiliary clamping block 500 will move away from the positioning hole 120, so as to facilitate the removal of the steel pipe structure from the positioning hole 120.

[0033] In some embodiments, the steel wire rope 600 passes through the groove wall of the positioning hole 120 and is located in the T-shaped sliding groove 130. The two ends of the steel wire rope 600 are respectively fixedly connected to the upper surface of the support base 700 and the T-shaped sliding portion 510 of the auxiliary clamping block 500, so that the steel wire rope 600 can move in the T-shaped sliding groove 130.

[0034] In some embodiments, a circular ring clamping platform 900 is fixedly provided on the upper surface of the support base 700. The circular ring clamping platform 900 is used for clamping with the inner surface of the steel pipe structure, so that the steel pipe structure can be rotationally limited on the support base 700. Preferably, a plurality of balls 910 are provided on the wall surface of the circular ring clamping platform 900. Each ball 910 can rotate on the wall surface of the circular ring clamping platform 900. The circular ring clamping platform 900 contacts the steel pipe structure through the balls 910, which can improve the rotation smoothness of the steel pipe structure, thereby facilitating seamless welding thereof.
