Description

Technical Field

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

[0002] Channel steel is a long steel strip with a groove-shaped cross section. It is a carbon structural steel used for construction and machinery. Its cross-sectional shape is a groove. Channel steel is welded using welding equipment during production and processing.

[0003] When welding the groove steel, the operator will place two groups of groove steel on the holder, and limit the groove steel on the holder through the cooperation of the limit plate and the bolt, and use the welding end to weld the limited groove steel. This processing method leads to the following shortcomings when used: because the two holders are welded to the welding equipment, the two holders can only limit one type of groove steel. If the two groups of groove steels are spliced ​​into a right-angle structure, it is necessary to replace the welding equipment, which affects the adaptability of the welding equipment and makes it impossible for the welding equipment to weld different types of groove steels. Because the groove steel is limited, the limit plate is used to press the groove steel, and the limit plate and the holder are connected by two nuts. This method requires a certain amount of time to disassemble the bolts when replacing the groove steel, which affects the efficiency and level of groove steel welding. Utility Model Content

[0004] The utility model aims to solve the problem that welding equipment in the prior art uses bolts to limit the groove steel, which causes inconvenience in disassembly, and proposes a groove steel welding device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A channel steel welding device comprises a processing table, a fixed seat, a movable seat, and a lifting welding head, wherein a driving rod is rotatably mounted on the fixed seat, and the lifting welding head is arranged on the driving rod, a matching operating table and a motor are fixedly mounted in the processing table, and a rotating shaft is fixedly connected to the output end of the motor, a traction rod is fixedly mounted on the rotating shaft, and a guide rod is fixedly mounted on the traction rod, and the movable seat is arranged on the guide rod;

[0007] The fixed seat and the movable seat are both provided with symmetrically arranged pressure rods in sliding sleeves, and a pressure plate is integrally connected between the two pressure rods, and a limit block for limiting the groove steel is fixedly installed on the pressure plate, and the fixed seat and the movable seat are both fixedly provided with symmetrically arranged sleeves, and a limit assembly for limiting the pressure rod is installed in the sleeve.

[0008] Preferably, the fixed seat and the movable seat are both concave structures, and the rotating shaft is vertically arranged.

[0009] Preferably, the movable seat and the guide rod extend to an upper end position outside the processing table, and a long guide hole for guiding the guide rod is provided on the processing table.

[0010] Preferably, the limiting assembly comprises a slider slidably sleeved in a sleeve, a spring is welded between the slider and the sleeve, and a positioning rod corresponding to the pressure rod is fixedly mounted on the slider.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4 A groove steel welding device comprises a processing table 1, a fixed seat 2, a movable seat 3, and a lifting welding head 5. A driving rod 4 is rotatably mounted on the fixed seat 2, and the lifting welding head 5 is arranged on the driving rod 4. By rotating the driving rod 4, the lifting welding head 5 can perform welding processing on groove steels at different positions;

[0023] A matching operating table and motor 6 are fixedly installed in the processing table 1. The operator can start and close the motor 6 according to the prior art, and a rotating shaft 7 is fixedly connected to the output end of the motor 6. The fixed seat 2 and the movable seat 3 are both concave structures, and the rotating shaft 7 is vertically arranged. A traction rod 8 is fixedly installed on the rotating shaft 7, and a guide rod 9 is fixedly installed on the traction rod 8. The movable seat 3 is arranged on the guide rod 9;

[0024] When welding the groove steel, if the two groups of groove steel are connected to form a straight structure, there is no need to start the motor 6. If the two groups of groove steel are connected to form a right-angle structure, the motor 6 is turned on to make the guide rod 9 drive the moving seat 3 to deflect to one side of the fixed seat 2, so that the welding equipment can perform welding processing on different types of groove steels;

[0025] The movable seat 3 and the guide rod 9 extend to the upper end position outside the processing table 1, and the processing table 1 is provided with a guide long hole 10 for guiding the guide rod 9. The guide long hole 10 guides the guide rod 9. Supplementary explanation: when the movable seat 3 deflects to the position on one side of the fixed seat 2, the groove steel on the movable seat 3 is first placed, according to the attached manual Figure 1 As shown, the guide slot 10 is an arc-shaped structure;

[0026] The fixed seat 2 and the movable seat 3 are both provided with symmetrically arranged pressure rods 12, and a pressure plate 13 is integrally connected between the two pressure rods 12, and a limit block 14 for limiting the channel steel is fixedly installed on the pressure plate 13, and symmetrically arranged sleeves 11 are fixedly installed on the fixed seat 2 and the movable seat 3;

[0027] A limiting assembly for limiting the pressure rod 12 is installed in the sleeve 11;

[0028] The limiting assembly includes a slider 16 slidably sleeved in the sleeve 11, and a spring 17 is welded between the slider 16 and the sleeve 11. A positioning rod 19 corresponding to the pressure rod 12 is fixedly installed on the slider 16. The spring 17 is horizontally welded, and a positioning hole 15 corresponding to the positioning rod 19 is opened on the pressure rod 12. By pressing the pressure plate 13, the positioning rod 19 is pushed to one side by the pressure rod 12. When the positioning hole 15 on the pressure rod 12 corresponds to the positioning rod 19, the position of the pressure plate 13 can be locked, so that the limiting block 14 can limit the groove steel, which makes it more convenient for the operator to limit the groove steel;

[0029] A clamping plate 18 is fixedly mounted on the slider 16, and a limiting hole for guiding the clamping plate 18 is provided on the sleeve 11. By pulling the clamping plate 18, the slider 16 drives the positioning rod 19 to disconnect from the pressure rod 12, making it more convenient for the operator to disassemble the channel steel;

[0030] It should be noted that the specific models and specifications of the lifting welding head 5 and the motor 6 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0031] The functional principle of the utility model can be explained through the following operation modes:

[0032] When welding the channel steel, check whether the motor 6 needs to be driven according to the required welding form;

[0033] When the two sets of groove steel are connected to form a straight groove steel, there is no need to start the motor 6, and the two sets of groove steel are placed in the fixed seat 2 and the movable seat 3 respectively, so that the connection ends of the two sets of groove steel can correspond to each other;

[0034] When the two groups of groove steels are spliced ​​to form a right-angle groove steel, the operating table sends a command to the motor 6, and the output end of the motor 6 drives the rotating shaft 7 to rotate. When the rotating shaft 7 rotates, it drives the traction rod 8 and the guide rod 9 to rotate. When the guide rod 9 rotates in the guide long hole 10, it drives the movable seat 3 to rotate, so that the movable seat 3 is deflected to the side of the fixed seat 2, and the two groups of groove steels are placed in the fixed seat 2 and the movable seat 3 respectively, so that the connection ends of the two groups of groove steels can correspond to each other;

[0035] The pressure plate 13 on the fixing seat 2 is manually pressed, so that the pressure plate 13 drives the pressure rod 12 to slide in the fixing seat 2. When the pressure rod 12 slides in the fixing seat 2, it flexibly abuts against the positioning rod 19. When the positioning rod 19 is abutted, it drives the slider 16 to slide in the sleeve 11. The spring 17 is stressed. The continuous downward movement of the pressure rod 12 causes the positioning rod 19 to extend into the positioning hole 15 under the action of the spring 17.

[0036] Repeat the above steps and press the pressure plate 13 on the movable seat 3. When the pressure plate 13 moves downward, it drives the limit block 14 to limit the channel steel. The position of the limit block 14 can be locked by the mutual cooperation between the positioning rod 19 and the positioning hole 15.

[0037] The driving rod 4 is pulled according to the welding position of the channel steel, and the lifting welding head 5 can perform welding processing on the channel steel below;

[0038] When the channel steel is welded, the two clamping plates 18 are pulled so that the clamping plates 18 slide in the limiting holes and drive the slider 16 and the positioning rod 19 to move, so that the positioning rod 19 is disconnected from the positioning hole 15 on the pressure rod 12, and the pressure plate 13 is pulled out to take out the welded channel steel.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
