Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and more specifically, to an adjustable automatic alignment clamp for assembling H-beams. Background Technology

[0002] Currently, H-beam welding is widely produced using assembly lines, and H-beam erecting machines are widely used. However, after the steel components are assembled, external welding equipment is needed to assist in welding them. Some companies have developed welding devices that can be mounted on the frame, but these devices lack flexibility and are difficult to weld irregular H-beams. The angle or working position of the welding torch is not adjustable, which significantly affects the welding effect. This type of erecting machine also has difficulty clamping H-beams that are bent irregularly, so its application range is limited.

[0003] To address the aforementioned issues, patent document publication number CN206536161UH describes a steel profile erecting machine, comprising a frame, a vertical pressing unit, a retractable side pressing unit, and a welding device. The vertical pressing unit includes an upper pressing device for pressing the top horizontal plate and a transmission roller located at the lower part of the frame for supporting the bottom horizontal plate. The side pressing units are symmetrically distributed on both sides of the frame, and the output end of each side pressing unit is movably equipped with a side pressing wheel for pressing the vertical plate. The welding device is slidably mounted on both sides of the frame and includes a cylinder, a welder, and a retractable welding torch mounted on the welder. The welder is rotatably mounted on the output end of the cylinder.

[0004] However, it still has some shortcomings in actual use. For example, before the H-beam is welded, it consists of three independent steel plates. When the assembly machine is welded, it lacks a mechanism to stand the steel plates vertically and fix them. It cannot fix the dispersed steel plates stably during welding, which will affect the welding accuracy.

[0005] Therefore, an adjustable automatic alignment fixture for H-beam assembly is proposed to solve the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable automatic alignment fixture for H-beam assembly, so as to solve the problem that the prior art assembly machine lacks a mechanism to vertically stand up and fix the steel plate during welding, and cannot fix the dispersed steel plate stably during welding, thus affecting the welding accuracy.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjustable automatic alignment fixture for assembling H-beams, comprising...

[0008] Hydraulic rod;

[0009] A placement plate, which is fixedly installed on the top of the hydraulic rod;

[0010] The vertical assembly consists of two sets, which are respectively arranged on both sides of the hydraulic rod;

[0011] The erecting assembly includes a base frame, a top plate, a limiting plate, a first motor, a connecting rod, a first connecting rod, and a second connecting rod. One side of the top plate is rotatably connected to the top edge of the base frame. The limiting plate is fixedly installed on the edge of the top plate. The first motor is fixedly installed on one side of the base frame. One end of the connecting rod is rotatably connected to the top of the base frame, and the other end of the connecting rod is fixedly connected to the output end of the first motor. One end of the first connecting rod is fixedly connected to the end of the connecting rod near the first motor, and the other end of the first connecting rod is rotatably connected to one end of the second connecting rod. The end of the second connecting rod away from the first connecting rod is rotatably connected to the bottom of the top plate.

[0012] The upright assembly also includes a rubber block, which is fixedly installed on the top of the base frame, with the top of the rubber block in contact with the bottom of the top plate.

[0013] It also includes an alignment component, which is disposed below the hydraulic rod.

[0014] The alignment assembly includes a strip plate, a second motor, a slide groove, a lead screw, and a sliding block. The center of the top of the strip plate is fixedly connected to the bottom end of the hydraulic rod. The second motor is fixedly installed at the end of the strip plate. The slide groove is formed on the top of the strip plate. One end of the lead screw is rotatably connected to the inside of the slide groove, and the other end of the lead screw is fixedly connected to the output end of the second motor. The outer surface of the sliding block is slidably connected to the inside of the slide groove, and the inside of the sliding block is threadedly connected to the outer surface of the lead screw. The top of the sliding block is fixedly connected to the bottom of the base frame.

[0015] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0016] In the above scheme, a hydraulic rod, a placement plate, and an erecting assembly are set up. Before welding begins, a steel plate is placed on top of the placement plate and the hydraulic rod is activated to raise it to a suitable height. The other two steel plates are placed on the two top plates respectively. The first motor is started, which drives the connecting rod to rotate, causing the first connecting rod to rotate, which in turn drives the second connecting rod to rotate, thereby causing the top plate to flip around the top of the base frame as an axis, thus flipping the steel plate to a vertical state. Through the above structure, the steel plates on both sides of the H-beam are flipped to a vertical state before welding, saving manpower and ensuring the accuracy of subsequent welding.

[0017] The alignment assembly is set up so that after the steel plate is flipped up, the second motor is started. The second motor drives the lead screw to rotate. When the lead screw rotates, it causes the sliding block to slide inside the slide groove, thereby driving the two sets of vertical components to move towards the middle, so that the two vertical steel plates are attached to the two sides of the horizontal steel plate. Through the above structure, the three steel plates used for welding the H-beam remain stable and avoid displacement during welding. Attached Figure Description

[0031] The upright assembly 3 also includes a rubber block 38, which is fixedly installed on the top of the base frame 31, and the top of the rubber block 38 is in contact with the bottom of the top plate 32.

[0032] It also includes an alignment component 4, which is located below the hydraulic rod 1.

[0033] The alignment component 4 includes a strip plate 41, a second motor 42, a slide groove 43, a lead screw 44, and a sliding block 45. The top center of the strip plate 41 is fixedly connected to the bottom end of the hydraulic rod 1. The second motor 42 is fixedly installed at the end of the strip plate 41.

[0036] After the steel plate is flipped up, the second motor 42 is started. The second motor 42 drives the lead screw 44 to rotate. When the lead screw 44 rotates, the sliding block 45 will slide inside the slide groove 43, thereby driving the two sets of vertical components 3 to move towards the middle, so that the two vertical steel plates are attached to the two sides of the horizontal steel plate.
