Positioning clamp for welding

Abstract

According to the positioning clamp for welding, the abutting block is arranged on the upper surface of the cross beam in the sliding mode, and the trapezoidal groove capable of clamping tubular steel structures such as steel pipes is formed in the upper surface of the abutting block. In actual use, if tubular steel structures such as steel pipes need to be fixed, the abutting blocks can be moved upwards to be located above the rolling wheels, and fixing and clamping are conducted through the screw rods on the support. When the plate-shaped steel structure needs to be fixed, the abutting block can be moved downwards to be located below the rolling wheel, and then the steel plate steel structure is clamped and fixed to the rolling wheel through the screw on the support. By the adoption of the structural design, different types of steel structures can be clamped and fixed, and subsequent welding treatment on the steel structures is facilitated.

Description

Technical Field

[0001] This application relates to the technical field of welding positioning jigs, and more specifically, to a positioning fixture for welding. Background Art

[0002] A fixture refers to a device used to fix a machining object during the mechanical manufacturing process, so that it occupies the correct position to receive construction or inspection, also known as a chuck. Generally speaking, any device used to quickly, conveniently and safely install a workpiece in any process of the technological process can be called a fixture.

[0003] A welding fixture is a fixture specifically used to fix, position and support workpieces to be welded. It can be used in various welding processes such as arc welding, gas welding, laser welding or plasma welding. In actual use, a welding fixture is used to clamp and position different types of steel structure components for subsequent welding treatment.

[0004] However, since the current welding fixtures can only clamp and position a single type of steel structure component (for example, due to its own structural limitations, a fixture for steel pipes can only clamp and fix steel pipe products), the welding positioning fixture has great limitations in use, so its practicability is relatively low. Utility Model Content

[0005] In view of this, the embodiments of this application provide a positioning fixture for welding to solve the problem of the relatively single functional use of welding fixtures in related technologies.

[0006] In order to achieve the above purpose, the embodiments of this application provide the following technical solutions:

[0013] In some possible implementation manners, positioning holes for cooperating with the fastening bolts and the positioning holes are arranged on the side surface of the cross beam.

[0014] In some possible implementation manners, both ends in the length direction of the cross beam are connected to the columns.

[0015] In some possible implementation manners, bearing seats are arranged at the top ends of the two columns, rotating shafts for cooperating with the bearing seats are arranged at both ends of the cross beam, and the cross beam can rotate relative to the columns.

Detailed implementation manners

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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 Figure 1 - Figure 2 shown, the positioning fixture for welding provided by the embodiment of the present application includes a frame 100, an abutting block 400, a fastening bolt 700, a bracket 800, and a roller 900. Among them, the frame 100 is the loading mechanism of the positioning fixture for welding. The frame 100 is formed by splicing two columns 200 and a cross beam 300. The cross beam 300 is arranged at the top positions of the two columns 200, and both ends in the length direction of the cross beam 300 are connected to the tops of the two columns 200. The cross beam 300 is also provided with a plurality of rectangular through holes 310 along the thickness direction, and the plurality of rectangular through holes 310 extend along the length direction of the cross beam 300.

[0028] The abutting block 400 is slidably arranged in the rectangular through-hole 310, and the abutting block 400 can move up and down relative to the cross beam 300 within the rectangular through-hole 310. A trapezoidal groove 410 is arranged on the upper surface of the abutting block 400, and the outer diameter of the top edge opening of the trapezoidal groove 410 is larger than that of the bottom edge opening. The abutting block 400 limits and fixes the tubular steel structure products through the trapezoidal groove 410. An L-shaped plate 500 is also fixedly arranged on one side surface of the abutting block 400. The L-shaped plate 500 and the side edge of the abutting block 400 jointly form a U-shaped sleeve 600. The U-shaped sleeve 600 is sleeved at the rectangular through-hole 310 of the cross beam 300, and the abutting block 400 realizes the structure of being slidably connected to the cross beam 300 through the U-shaped sleeve 600. In addition, a vertically arranged positioning hole 510 is opened in the vertical part of the L-shaped plate 500 along the thickness direction.

[0029] In this embodiment, a fastening bolt 700 is inserted into the positioning hole 510. The fastening bolt 700 can penetrate through the positioning hole 510 and abut against the side surface of the cross beam 300, so as to achieve the purpose of fixing the abutting block 400 at the preset position of the cross beam 300 through the fastening bolt 700. Preferably, the side surface of the cross beam 300 can be provided with a positioning hole 510 adapted to the positioning hole 510, so that the end of the fastening bolt 700 can penetrate through the positioning hole 510 of the L-shaped plate 500 and extend into the positioning hole 510 on the side surface of the cross beam 300, thereby improving the connection stability of the abutting block 400 relative to the cross beam 300.

[0030] The bracket 800 is arranged on the upper surface of the cross beam 300 and beside the rectangular through-hole 310. Specifically, a screw rod 810 is threadedly connected to the top end of the bracket 800. The screw rod 810 is arranged vertically downward, and the screw rod 810 is located above the rectangular through-hole 310 and the abutting block 400. The screw rod 810 moves up and down by means of threaded connection at the top end of the bracket 800. When the screw rod 810 moves towards the direction close to the abutting block 400, the screw rod 810 can clamp and fix the tubular steel structure component clamped in the trapezoidal groove 410.

[0031] In addition, a plurality of rollers 900 are arranged on the upper surface of the cross beam 300. The plurality of rollers 900 are rotatably arranged on the upper surface of the cross beam 300, and the outer wall surfaces of the plurality of rollers 900 are all higher than the upper surface of the cross beam 300.

[0032] In the positioning fixture for welding provided in the embodiments of the present application, an abutting block 400 is slidably arranged on the upper surface of the cross beam 300, and a trapezoidal groove 410 for clamping tubular steel structures such as steel pipes is arranged on the upper surface of the abutting block 400. During actual use, when it is necessary to fix a tubular steel structure such as a steel pipe, the abutting block 400 can be moved upward and located above the roller 900, and fixed and clamped by the screw 810 on the bracket 800. When it is necessary to fix a plate-shaped steel structure, the abutting block 400 can be moved downward and located below the roller 900, and then the steel plate-shaped steel structure is clamped and fixed on the roller 900 by the screw 810 on the bracket 800. With the above structural design, different types of steel structures can be clamped and fixed, facilitating subsequent welding treatment.

[0033] In some embodiments, bearing seats 210 are arranged at the tops of both columns 200, and rotating shafts 220 are arranged at both ends of the cross beam 300 in the length direction. The rotating shafts 220 are inserted into the inner rings of the bearing seats 210 and fixedly connected to the inner rings, so that the cross beam 300 can rotate relative to the columns 200.

[0034] Preferably, as Figure 2 shown, a disk 320 is further arranged at one end of the cross beam 300 in the length direction. The disk 320 is provided with a plurality of holes 321 along the thickness direction, and the plurality of holes 321 are circumferentially distributed on the disk 320. In addition, a quick clamp 330 is arranged at the top of the column 200. The quick clamp 330 is located beside the holes 321 of the disk 320. The clamp body of the quick clamp 330 can extend into the holes 321 to fix the cross beam 300 at a preset position through the disk 320. With the above structural design, the steel structure component to be welded that is clamped and fixed can be rotated according to the needs of the staff, facilitating the staff to weld the steel structure component from multiple different angles, thereby improving the efficiency of the welding treatment.
