Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically a welding fixture. Background Technology

[0002] Welding fixtures are specialized tooling equipment used to fix, position, and support welding workpieces. Their core function is to ensure the accurate position and stable state of the workpiece during the welding process, thereby guaranteeing welding quality and efficiency. They can solve the problems of inaccurate workpiece placement and displacement during welding, and are an indispensable tool in mass welding production and high-precision welding operations.

[0003] For example, the authorization announcement number "CN216462352U" is a welding fixture. By setting the lower pressure part and the carrier part opposite to each other, the lower pressure part can cooperate with the carrier part and the pressing part on the lower pressure part can hold the component to be welded placed on the part to be welded. Most of the workpieces to be welded by the existing welding fixture are relatively precise welding components. Therefore, during the welding process, it is necessary to ensure that the welding part and the positioning groove inside the welding fixture are placed stably and accurately at all times. Once an accidental touch occurs during operation and causes the welding workpiece to move or shift, the welding position will be incorrect, affecting the final processing effect. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing welding fixtures have the problem that if the welding workpiece is moved or shifted due to accidental touch during operation, the welding position will be incorrect and the final processing effect will be affected. Therefore, a welding fixture is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a welding fixture, including a base plate, vertical plates and positioning grooves. The positioning grooves are fixedly connected to the inner side of the base plate. Multiple vertical plates are fixedly installed on both sides of the top of the base plate. A welding workpiece fixing structure is provided above the base plate, and a welding workpiece positioning structure is provided at the front end of the base plate.

[0007] In this setup, the positioning groove is used to embed the workpiece assembly to be welded into the base plate for fixation. The base plate and multiple vertical plates on the outside are all made of metal. The base plate and vertical plates are usually machined from No. 45 steel, which makes the structure sturdy and facilitates the installation of fixtures on the welding platform for use.

[0008] Preferably, the welding workpiece positioning structure includes splicing blocks and outer plates. Two splicing blocks are connected to the front end of the base plate by bolts and threads. An outer plate is fixedly installed on the outer side of the two splicing blocks. A crossbeam is fixedly connected above the two outer plates. Multiple mounting holes are fixedly opened on the inner side of the crossbeam. A semiconductor laser is threadedly connected to the inner side of the mounting holes. A control button is fixedly installed above the semiconductor laser. A connection line is fixedly connected to the rear side of the semiconductor laser.

[0009] This setup uses a gallium arsenide semiconductor laser, powered by DC or pulsed current. It utilizes the cleavage surface of the semiconductor chip to form a common visible light beam, which is projected forward and illuminates the workpiece being welded. If the workpiece shifts, the projected visible light beam will shift from its original position, making it easy for staff to adjust and reducing inaccurate welding caused by accidental shifting of the workpiece.

[0010] Preferably, the front end of the external plate is movably connected to the edge of the base plate, and the front end of the semiconductor laser is perpendicular to the crossbeam.

[0011] In this configuration, the splicing block can carry the stainless steel outer plate on the back and insert it into the inner side of the base plate for positioning. Then, the connection is achieved by tightening the bolts. A horizontal plate is welded on top of the two protruding outer plates and placed horizontally on the crossbeam. Threaded holes are drilled at equal intervals on the inner side of the crossbeam, so that the semiconductor laser can be rotated and screwed into the corresponding placement hole.

[0012] Preferably, the welding workpiece fixing structure includes a frame and a positioning frame. The frame is fixedly installed on both sides of the top of the base plate. A movable clamping plate is slidably connected to the inner side of the frame. A connecting piece is movably connected to the rear side of the movable clamping plate. The positioning frame is fixedly connected to one side above the base plate. A cylinder is fixedly installed at the front end of the positioning frame.

[0013] In this setup, the frame is welded to both sides of the base plate for fixation. The movable clamping plate is used to slide forward and clamp the workpiece that needs to be fixed. The cylinder fixed at the front end of the positioning frame can be started at any time. The cylinder 4 generates a pushing force to drive the movable clamping plate to slide along the inner side of the frame. The connecting frame can provide the movable clamping plate with sufficient space to move, and then the workpiece is clamped as required.

[0014] Preferably, the front end of the cylinder is movably connected to the rear side of the connector via a pin, and the movable clamping plate is slidably connected to the inner side of the positioning groove.

[0015] Preferably, protrusions are fixedly installed on the inner walls of the two frames, and a travel limit block is fixedly connected to the front end of the protrusion.

[0016] In this configuration, the protrusions are welded laterally to the inner sides of the two frames. The front end of the protrusions protrudes and fixes two opposing travel limit blocks. The travel limit blocks restrict the extreme sliding position of the sliding clamp, preventing damage caused by excessive compression of the workpiece.

[0017] The welding fixture proposed in this utility model has the following advantages: the semiconductor laser is a gallium arsenide semiconductor chip, which is powered by DC or pulsed current. It uses the cleavage surface of the semiconductor chip to form a common visible light beam. The visible light beam is projected forward and will illuminate the workpiece being welded. Once the workpiece is shifted, the projected visible light beam will shift from the original positioning point, which makes it easy to remind the staff to pay attention to the adjustment and reduces the problem of inaccurate welding caused by accidental shift of the workpiece.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] Example:

[0027] Please see Figure 1-6In this embodiment, a welding fixture includes a base plate 1, vertical plates 2, and positioning grooves 3. The positioning grooves 3 are fixedly connected to the inner side of the base plate 1. The positioning grooves 3 are used for the workpieces to be welded to be embedded into the base plate 1 for fixation. The base plate 1 and the multiple vertical plates 2 on the outer side are all made of metal. The base plate 1 and the vertical plates 2 are usually processed from 45# steel, with a sturdy structure, which facilitates the installation of the fixture on the welding platform for use. The multiple vertical plates 2 are fixedly installed on both sides of the top of the base plate 1. A welding workpiece fixing structure 4 is provided above the base plate 1, and a welding workpiece positioning structure 5 is provided at the front end of the base plate 1.

[0028] The welding workpiece positioning structure 5 includes splicing blocks 51 and outer plates 52. Two splicing blocks 51 are connected to the front end of the base plate 1 by bolt threads. The splicing blocks 51 can carry the stainless steel outer plates 52 on the rear side and insert them into the inner side of the base plate 1 for positioning. Then, the connection is achieved by tightening the bolts. The outer plates 52 are fixedly installed on the outer sides of the two splicing blocks 51. A horizontally placed crossbeam 53 is welded horizontally above the two protruding outer plates 52. Threaded mounting holes 54 are drilled at equal intervals on the inner side of the crossbeam 53, so that the semiconductor laser 56 can be rotated and screwed into the corresponding mounting holes 54. The crossbeam 53 is fixedly connected above the two outer plates 52. Multiple mounting holes 54 are fixedly opened on the inner side of the crossbeam 53. The semiconductor laser 56 is threadedly connected to the inner side of the mounting holes 54. The conductor laser 56 is a gallium arsenide semiconductor chip, powered by DC or pulsed current. It uses the cleavage surface of the semiconductor chip to form a common visible light beam, which is projected forward and illuminates the workpiece being welded. If the workpiece shifts, the projected visible light beam will also shift from its original position, allowing the operator to easily adjust it. A control button 55 is fixedly installed on the top of the semiconductor laser 56, which can be manually pressed to turn the laser on or off. A power supply line 57 is fixedly connected to the rear of the semiconductor laser 56, which is powered by an external power supply (not shown in the power supply diagram).

[0029] The front end of the external plate 52 is movably connected to the edge of the base plate 1, and the front end of the semiconductor laser 56 is perpendicular to the crossbeam 53.

[0030] The welding workpiece fixing structure 4 includes a frame 41 and a positioning frame 42. The frame 41 is fixedly installed on both sides of the top of the base plate 1. The frame 41 is welded to both sides of the base plate 1 for fixation. A movable clamping plate 45 is slidably connected to the inner side of the frame 41. The movable clamping plate 45 is used to slide forward to clamp the workpiece that needs to be fixed. The cylinder 43 fixed at the front end of the positioning frame 42 can start working at any time. The cylinder 43 generates a pushing force to drive the movable clamping plate 45 to slide along the inner side of the frame 41. The connecting frame 44 can provide sufficient space for the movable clamping plate 45 to achieve the clamping requirements of the workpiece. A connecting piece 44 is movably connected to the rear side of the movable clamping plate 45. The positioning frame 42 is fixedly connected to the upper side of the base plate 1. The cylinder 43 is fixedly installed at the front end of the positioning frame 42.

[0031] The front end of the cylinder 43 is movably connected to the rear side of the connector 44 via a pin, and the movable clamping plate 45 is slidably connected to the inner side of the positioning groove 3.

[0032] The inner walls of the two frames 41 are fixedly installed with protrusions 61. The protrusions 61 are horizontally welded to the inner side of the two frames 41. The front end of the protrusions 61 protrudes and fixes two oppositely arranged travel limit blocks 62. The travel limit blocks 62 will limit the extreme sliding position of the sliding clamp 45 and can prevent damage caused by excessive compression of the workpiece. The front end of the protrusions 61 is fixedly connected to the travel limit blocks 62.

[0033] Working principle:

[0034] Welding fixtures are specialized tooling equipment used to fix, position, and support welding workpieces. Their core function is to ensure the accurate position and stable condition of the workpiece during the welding process, thereby guaranteeing welding quality and efficiency.

[0035] The positioning groove 3 is used to embed the workpiece group that needs to be welded into the base plate 1 for fixation. The base plate 1 and the multiple vertical plates 2 on the outside are all made of metal. The base plate 1 and the vertical plates 2 are usually processed from No. 45 steel, which makes the structure sturdy and convenient for the fixture to be installed on the welding platform for use.

[0036] The splicing block 51 carries the stainless steel outer plate 52 on its rear side, which is inserted into the inner side of the base plate 1 for positioning. The connection is then achieved by tightening bolts. A horizontally mounted plate is welded above the two protruding outer plates 52 and placed on a crossbeam 53. Threaded mounting holes 54 are drilled at equal intervals on the inner side of the crossbeam 53, allowing the semiconductor laser 56 to be rotated and screwed into the corresponding mounting holes 54. The semiconductor laser 56 is a gallium arsenide semiconductor chip, powered by DC or pulsed current. It utilizes the cleavage surface of the semiconductor chip to form a common visible light beam, which points directly forward. The projected beam will illuminate the workpiece being welded. If the workpiece shifts, the projected visible light beam will shift from its original position, making it easy to remind the staff to make adjustments. A control button 55 is fixedly installed on the top of the semiconductor laser 56. The control button 55 can be manually pressed to turn the semiconductor laser 56 on or off, making it easy to control the semiconductor laser 56. A connection line 57 is fixedly connected to the rear of the semiconductor laser 56. The connection line 57 relies on an external power supply to power the semiconductor laser 56 (not marked in the power supply diagram).

[0037] The frame 41 is welded to both sides of the base plate 1 for fixation. The movable clamping plate 45 is used to slide forward to clamp the workpiece that needs to be fixed. The cylinder 43 fixed at the front end of the positioning frame 42 can start working at any time. The cylinder 43 generates a pushing force to drive the movable clamping plate 45 to slide along the inner side of the frame 41. The connecting frame 44 can provide sufficient space for the movable clamping plate 45 to move, and then achieve the clamping requirements of the workpiece.
