[0005] The purpose of this invention is to address the following shortcomings in the prior art: when two workpieces need to be welded at a certain angle, it is inconvenient to use and there is room for improvement. Therefore, this invention proposes a welding fixture for manufacturing mechanical equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

Mounting plates are installed at both ends of the support frame via lifting components. A placement plate is fixedly installed between the two mounting plates. The placement plate has a second clamping component for clamping the workpiece. The placement plate has a rectangular opening, in which a trapezoidal block with a trapezoidal longitudinal section is slidably installed horizontally via an adjusting component. Both sides of the trapezoidal block are in sliding contact with the inner wall of the rectangular opening. The slider has a locking component for locking itself.

[0009] As a preferred embodiment, the fixed base is provided with a movable groove. The first clamping assembly includes a first threaded rod with opposite thread directions at its left and right ends, two symmetrically threaded movable blocks sleeved on the first threaded rod, and two clamping blocks respectively fixedly installed on the two movable blocks. The two movable blocks are horizontally slidably installed in the movable groove. One end of the first threaded rod extends out of the movable groove and is fixedly installed with a rotating block.

[0010] As a preferred embodiment, the support frame is provided with a lifting hole, and the lifting assembly includes a second threaded rod that is vertically rotatably installed in the lifting hole and a lifting block that is threaded onto the second threaded rod. The lifting block is vertically slidably installed in the lifting groove and is fixedly connected to the mounting plate. One end of the second threaded rod passes through the lifting hole and is fixedly installed with a first adjusting wheel.

[0011] As a preferred embodiment, the second clamping assembly includes a rectangular block symmetrically slidably mounted on the lower surface of the placement plate via an elastic component, two positioning plates respectively fixedly mounted on the two rectangular blocks, and two rotating disks respectively rotatably mounted on the two positioning plates, the two rotating disks being symmetrically arranged on the placement plate.

[0012] As a preferred embodiment, the elastic component includes a slide rail fixedly mounted on the lower surface of the placement plate by a fixing block and two first telescopic springs symmetrically sleeved on the slide rail, with the two ends of the first telescopic springs fixedly connected to the fixing block and the rectangular block, respectively.

[0013] As a preferred embodiment, the adjustment assembly includes a third threaded rod rotatably mounted in a rectangular opening, a U-shaped frame threaded onto the third threaded rod, and a second adjustment wheel fixedly mounted on one end of the third threaded rod. The U-shaped frame is fixedly mounted on the side of the placement plate, and the trapezoidal block is threaded onto the third threaded rod.

[0014] As a preferred embodiment, the locking assembly includes a mounting block fixedly mounted on the slider, a movable rod vertically mounted on the mounting block via an elastic component, a resistance block fixedly mounted on one end of the movable rod, and an annular rubber pad fixedly mounted on the base. The resistance block is in contact with the annular rubber pad. The mounting block has a movable hole, and the movable rod is vertically slidably mounted in the movable hole. Multiple steel needles are fixedly mounted on the lower surface of the resistance block.

[0015] As a preferred embodiment, the elastic component includes a pull rod fixedly installed at the end of the moving rod away from the resistance block and a second telescopic spring sleeved on the moving rod, with the two ends of the second telescopic spring fixedly connected to the pull rod and the mounting block, respectively.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Reference Figures 1-9 A welding fixture for manufacturing mechanical equipment includes a base 1, a fixed seat 2 fixedly installed at the center of the base 1, a first clamping assembly for clamping workpieces on the fixed seat 2, a movable groove on the fixed seat 2, and the first clamping assembly includes a first threaded rod 9 with opposite thread directions at its left and right ends, two symmetrically threaded movable blocks 10 sleeved on the first threaded rod 9, and two clamping blocks 11 respectively fixedly installed on the two movable blocks 10. The two movable blocks 10 are horizontally slidably installed in the movable groove, and one end of the first threaded rod 9 extends out of the movable groove and is fixedly installed with a rotating block 12.

[0035] The fixed base 2 is installed at the center of the base 1. When clamping and fixing one of the workpieces, the workpiece is placed between the two clamping blocks 11. Then, the rotating block 12 is rotated, which drives the first threaded rod 9 to rotate. Since the threads at the left and right ends of the first threaded rod 9 are opposite, the two moving blocks 10 will move closer to each other. Then, the two moving blocks 10 will drive the two clamping blocks 11 to move closer to each other until both clamping blocks 11 are in contact with the workpiece, thus clamping and fixing the workpiece on the fixed base 2.

[0036] An annular groove is provided on the base 1, and a slider 3 is slidably installed in the annular groove. A U-shaped support frame 5 is fixedly installed on the slider 3. Mounting plates 6 are installed at both ends of the support frame 5 through lifting components. A placement plate 7 is fixedly installed between the two mounting plates 6. A second clamping component for clamping the workpiece is provided on the placement plate 7. A rectangular opening is provided on the placement plate 7. A trapezoidal block 8 with a trapezoidal longitudinal section is horizontally slidably installed in the rectangular opening through an adjustment component. Both sides of the trapezoidal block 8 are in sliding contact with the inner wall of the rectangular opening. A locking component for locking itself is provided on the slider 3.

[0037] When fixing another workpiece, the workpiece is placed on the placement plate 7 and clamped on the placement plate 7 by the second clamping assembly. Then, the height of the placement plate 7 is adjusted by the lifting assembly so that the welding joints of the two workpieces are on the same horizontal plane. The slider 3 can be moved in the annular groove, thereby causing the workpiece to rotate around the fixed seat 2, so that the welding joints of the two workpieces come into contact. Then, the trapezoidal block 8 is moved on the placement plate 7 by the adjusting assembly. When the trapezoidal block 8 moves, the tilt angle of the workpiece on the placement plate 7 can be adjusted to adjust the angle of the two workpieces to the required welding angle. Finally, welding is performed. When fixing two workpieces, it is convenient to fix the two workpieces at a certain angle before welding. The operation is convenient and effectively improves the practicality of the device.

[0038] The support frame 5 has a lifting hole. The lifting assembly includes a second threaded rod 13 that is vertically rotatably installed in the lifting hole and a lifting block 14 that is threaded onto the second threaded rod 13. The lifting block 14 is vertically slidably installed in the lifting groove and is fixedly connected to the mounting plate 6. One end of the second threaded rod 13 passes through the lifting hole and is fixedly installed with a first adjusting wheel 15. When it is necessary to adjust the height of the placement plate 7, the two first adjusting wheels 15 on the support frame 5 can be rotated by hand at the same time, thereby driving the two second threaded rods 13 to rotate simultaneously. Under the action of the second threaded rods 13, the two lifting blocks 14 can be driven to move up and down on the support frame 5 at the same time, thereby driving the placement plate 7 to move up and down on the support frame 5 through the mounting plate 6, realizing the adjustment of the height of the placement plate 7, so that the welding joints of the two workpieces are on the same horizontal plane.

[0039] The second clamping assembly includes a rectangular block 16 symmetrically slidably mounted on the lower surface of the placement plate 7 via an elastic component, two positioning plates 17 respectively fixedly mounted on the two rectangular blocks 16, and two rotating disks 18 respectively rotatably mounted on the two positioning plates 17. The two rotating disks 18 are symmetrically arranged on the placement plate 7. The elastic component includes a slide rail 19 fixedly mounted on the lower surface of the placement plate 7 via a fixing block and two first telescopic springs 20 symmetrically sleeved on the slide rail 19. The two ends of the first telescopic springs 20 are fixedly connected to the fixing block and the rectangular block 16 respectively. Under the action of the elastic force of the first telescopic springs 20, the two rectangular blocks 16 tend to move closer to each other. When clamping and fixing one of the workpieces, the two positioning plates 17 are driven away from each other, the first telescopic springs 20 are compressed, and then the workpiece is placed between the two positioning plates 17. The two positioning plates 17 are released, and under the action of the elastic force of the first telescopic springs 20, the rectangular blocks 16 drive the two positioning plates 17 to move closer to each other until the two rotating disks 18 contact the two sides of the workpiece. Under the action of the elastic force, the workpiece is clamped and fixed on the placement plate 7.

[0040] The adjustment assembly includes a third threaded rod 21 rotatably mounted in a rectangular opening, a U-shaped frame 22 threaded onto the third threaded rod 21, and a second adjusting wheel 23 fixedly mounted on one end of the third threaded rod 21. The U-shaped frame 22 is fixedly mounted on the side of the placement plate 7, and the trapezoidal block 8 is threaded onto the third threaded rod 21. When the workpiece is clamped and fixed on the placement plate 7, the third threaded rod 21 can be rotated by rotating the second adjusting wheel 23. When the third threaded rod 21 rotates, it can move the trapezoidal block 8 within the rectangular opening. When the inclined surface of the trapezoidal block 8 contacts one end of the workpiece, the movement of the trapezoidal block 8 can cause the workpiece to rotate between the two positioning plates 17. When rotating, it causes the rotating disk 18 to rotate on the positioning plate 17, thereby adjusting the welding angle of the two workpieces.

[0041] The locking assembly includes a mounting block 24 fixedly mounted on the slider 3, a moving rod 25 vertically mounted on the mounting block 24 via an elastic component, a resistance block 26 fixedly mounted on one end of the moving rod 25, and an annular rubber pad 27 fixedly mounted on the base 1. The resistance block 26 is in contact with the annular rubber pad 27. The mounting block 24 has a moving hole, and the moving rod 25 is vertically slidably mounted in the moving hole. Multiple steel needles 30 are fixedly mounted on the lower surface of the resistance block 26. The elastic component includes a pull rod 28 fixedly mounted on the end of the moving rod 25 away from the resistance block 26 and a second telescopic spring 29 sleeved on the moving rod 25. The two ends of the second telescopic spring 29 are fixedly connected to the pull rod 28 and the mounting block 24, respectively.

[0042] When the two workpieces are respectively mounted on the fixed base 2 and the placement plate 7, the pull rod 28 can be pulled to move the moving rod 25 upward. The second telescopic spring 29 is compressed, causing the resistance block 26 to separate from the annular rubber pad 27. At the same time, multiple steel needles 30 are also separated from the annular rubber pad 27, which in turn causes the slider 3 to move in the annular groove. This allows the workpiece on the placement plate 7 to rotate around the workpiece on the fixed base 2, bringing the welding joints of the two workpieces into contact. Then, the pull rod 28 is released. Under the elastic force of the second telescopic spring 29, the moving rod 25 moves the resistance block 26 towards the annular rubber pad 27 until the resistance block 26 contacts the annular rubber pad 27. Under the action of friction, the slider 3 is restricted from sliding in the annular groove. At the same time, when the resistance block 26 contacts the annular rubber pad 27, multiple steel needles 30 will insert into the annular rubber pad 27, further increasing the resistance between the resistance block 26 and the annular rubber pad 27, making the locking of the slider 3 more stable, preventing the two workpieces from moving relative to each other during welding, and avoiding deviations in the welding angle.

[0043] Fans 31 are fixedly installed on both sides of the slider 3. A fume recovery pipe 32 and a suction pipe 33 are installed on the fans 31. A suction hood 34 is fixedly connected to the end of the suction pipe 33 away from the fans 31. A recycling component for recycling debris is installed on the suction pipe 33. When the fans 31 are in use, a large suction force can be generated at the suction hood 34 through the suction pipe 33. When welding, the fans 31 are started, so that the fumes generated during welding can be sucked into the suction pipe 33 through the suction hood 34. Then, the fumes are sucked into the fume recovery pipe 32 by the fans 31. One end of the fume recovery pipe 32 is connected to a fume purification device (the fume purification device is existing technology and is not shown in the figure) to collect the fumes generated during welding, so as to avoid the fumes being emitted into the air, polluting the environment and affecting the health of the workers.

[0044] The recycling component includes a connector 35 fixedly connected to the suction pipe 33, a waste collection tank 36 threadedly connected to the connector 35, and a filter plate 4 inclinedly fixedly installed on the suction pipe 33. The connector 35 is connected to the suction pipe 33, and the filter plate 4 is located directly above the connector 35. When the fan 31 is running, it can suck the waste generated during welding into the suction pipe 33. Under the action of the filter plate 4, the waste is blocked in the suction pipe 33, while the flue gas passes through the suction pipe 33. Since the filter plate 4 is inclinedly installed in the suction pipe 33 and located above the connector 35, the filtered waste will automatically fall into the waste collection tank 36, thereby collecting the waste generated during welding, preventing the waste from falling onto the base 1, and facilitating later cleaning.

[0045] In this invention, when welding two workpieces, one workpiece is clamped and fixed on the fixing base 2. When fixing the other workpiece, the workpiece is placed on the placement plate 7 and clamped on the placement plate 7 by the second clamping assembly. Then, the height of the placement plate 7 is adjusted by the lifting assembly so that the welding joints of the two workpieces are on the same horizontal plane. The workpieces can be rotated around the fixing base 2 by moving the slider 3 in the annular groove so that the welding joints of the two workpieces come into contact. Then, the trapezoidal block 8 is moved on the placement plate 7 by the adjusting assembly. When the trapezoidal block 8 moves, the tilt angle of the workpieces on the placement plate 7 can be adjusted so that the angle of the two workpieces is adjusted to the required welding angle. Finally, welding is performed. When fixing two workpieces, it is convenient to fix the two workpieces at a certain angle before welding. The operation is convenient and effectively improves the practicality of the device.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
