Description

Technical Field

[0001] This invention application relates to the field of fixture technology, specifically to a welding fixture for machining mechanical equipment. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Modern welding uses various energy sources, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. Besides its use in factories, welding can be performed in a variety of environments. Pipelines are devices made up of pipes, pipe fittings, and valves used to transport gases, liquids, or fluids containing solid particles. Typically, fluids are pressurized by blowers, compressors, pumps, and boilers, flowing from high-pressure areas to low-pressure areas in pipelines. They can also be transported using their own pressure or gravity. Pipelines have a wide range of applications, primarily in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects, and various industrial installations. When welding two pipe fittings, they need to be placed horizontally aligned before welding the joint. However, the fittings are prone to movement, leading to poor welding results and affecting weld quality. Therefore, clamps are needed to hold the fittings in place. Patent document CN220806005U discloses a welding fixture for machining. This assembly includes a fixed base, on which a clamping unit is fixedly connected. The clamping unit is equipped with a lifting cylinder, and a connecting seat is fixedly connected to the output end of the lifting cylinder. The connecting seat is fixedly connected to another set of clamping units. This utility model belongs to the field of tooling and fixture technology, specifically a welding fixture for machining. It effectively solves the problems of currently available welding fixtures for machining having relatively simple structures, inconvenient installation and disassembly, and increased maintenance and production costs; and the lack of clamping position indication, which easily leads to workpieces falling due to inadequate clamping. This invention enables convenient and quick disassembly of the clamping structure, reducing equipment maintenance costs, and improves efficiency by providing feedback on the clamping position through a sensing device.

[0003] In actual use, the aforementioned welding fixture for machining cannot adjust the angle of the metal tube after it is fixed and clamped. This results in the need to readjust the position of the metal tube after welding the top, which affects the welding efficiency of the metal tube. Therefore, a welding fixture for machining is proposed. Summary of the Invention

[0004] To address the aforementioned problems, a welding fixture for machining mechanical equipment is provided. By adjusting the angle of the metal material, it is easier to weld the unwelded parts of the metal material, thereby increasing the welding rate of the metal material.

[0005] To address the above problems, this invention provides a welding fixture for machining mechanical equipment, comprising: A placement plate, the top surface of which is provided with two mounting plates, and a placement hole is provided on one side of the mounting plate; A rotating ring is movably fitted inside the placement hole, and two pressing blocks are provided inside the rotating ring; A placement slot is provided on the top surface of the placement plate, and a collection box is movably installed inside the placement slot; An adjusting component, disposed inside the rotating ring, is used to adjust the position of the two extrusion blocks; A positioning component is disposed on the top surface of the placement plate and is used to position the mounting plate.

[0006] As a further supplement to this application, the adjustment component includes: A plurality of mounting slots are provided, all of which are formed on the inner wall of the rotating ring, and a cylinder is fixedly connected inside the mounting slots; Two connecting plates are disposed inside the rotating ring. The top surface of the connecting plates is fixedly connected to the bottom surface of the two cylinder telescopic shafts. The outer wall of the rotating ring is provided with a plurality of tooth grooves. The top surface of the mounting plate is provided with an adjustment hole. A gear is disposed inside the adjustment hole, and the gear meshes with the tooth grooves. A connector is disposed on the bottom surface of the extrusion block and is used to connect the extrusion block to the connecting plate.

[0007] As a further supplement to this application, the connector includes: Two connecting blocks are fixedly connected to the bottom surface of the extrusion block. Two connecting holes are opened on one side of the connecting plate, and the connecting blocks are movably fitted together with the connecting holes. Fixing holes are formed on the top surface of the connecting plate.

[0008] As a further supplement to this application, a bolt is movably fitted inside the fixing hole, a rotating groove is opened on the bottom surface of the extrusion block, the bolt is threadedly connected to the rotating groove, a limit groove is opened on the inner wall surface of the placement hole, a limit ring is fixedly connected to the outer wall surface of the rotating ring, and the limit ring is rotatably installed with the limit groove.

[0009] As a further supplement to this application, a drive motor is fixedly connected to the top surface of the mounting plate, and one end of the drive shaft of the drive motor is fixedly connected to one end of the gear.

[0010] As a further supplement to this application, the positioning component includes: Two adjustment slots are provided, both of which are formed on the top surface of the placement plate. An adjustment block is fixedly connected to the bottom surface of the mounting plate, and the adjustment block is slidably installed together with the adjustment slot. A rotating hole is provided on one side of the adjusting block; An adjusting element is disposed inside the rotating hole and is used to adjust the position of the adjusting block.

[0011] As a further supplement to this application, the adjusting element includes: A lead screw is threaded into the interior of the rotating hole, and a motor slot is provided on one side of the adjustment groove. A stepper motor is fixedly connected inside the motor slot. One end of the stepper motor's drive shaft is fixedly connected to one end of the lead screw. A fixing slot is provided on one side of the adjustment slot, and one end of the lead screw is rotatably mounted to the fixing slot.

[0012] As a further supplement to this application, sliding grooves are provided on both the left and right sides of the placement plate, and limiting plates are fixedly connected to both the left and right sides of the mounting plate. A sliding block is fixedly connected to one side of the limiting plate, and the sliding block is slidably installed together with the sliding groove.

[0013] The advantages of this invention application compared to the prior art are: 1. This application incorporates rotating rings. When workers place the metal materials to be welded inside the two rotating rings, they adjust the positions of the two pressing blocks using an adjusting component. These pressing blocks work together to clamp and fix the metal materials inside the rotating rings. A positioning component positions the two mounting plates, controlling their position on the top surface of the placement plate. This ensures the welding points of the two metal materials fit together, facilitating subsequent welding. A gear, rotating within the adjusting hole, drives the rotating rings, adjusting the angle of the metal materials. This allows for welding of unwelded areas, improving welding efficiency and enabling welding of different locations on the metal materials. A collection box collects the metal debris generated during welding at the center of the top surface of the placement plate, allowing the debris to fall downwards under its own weight.

[0014] 2. This application uses a cylinder. When the cylinder's telescopic shaft moves the connecting plate, the extrusion block can be fixed on the top surface of the connecting plate because the connecting block and the connecting hole are movably fitted together. At this time, the moving connecting plate can move the extrusion block, thereby facilitating the control of the distance between the two extrusion blocks. This allows metal materials of different sizes and thicknesses to be fixed inside the rotating ring. Since the limiting ring and the limiting groove are movably fitted together, the limiting ring can limit the rotating ring, thereby preventing the rotating ring from moving out of the placement hole.

[0015] 3. This application sets up a drive motor and controls two drive motors to work simultaneously, so that two gears can synchronously drive two rotating rings to rotate, thereby adjusting the angle of the fixed metal material inside the rotating rings. By setting up a stepper motor, when the drive shaft of the stepper motor drives the lead screw to rotate, the adjustment block can move inside the adjustment groove. The adjustment block can drive the mounting plate to move when it moves, which facilitates the subsequent adjustment of the position of the mounting plate on the top surface of the placement plate.

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this invention application, the invention application will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0025] See Figures 1-7 As shown, a welding fixture for machining mechanical equipment includes: a placement plate 1, two mounting plates 2 on the top surface of the placement plate 1, a placement hole 3 on one side of the mounting plate 2, a rotating ring 4 movably fitted inside the placement hole 3, two extrusion blocks 5 inside the rotating ring 4, a placement groove 6 on the top surface of the placement plate 1, a collection box 7 movably installed inside the placement groove 6, several toothed grooves 18 on the outer wall of the rotating ring 4, an adjustment hole 19 on the top surface of the mounting plate 2, a gear 20 inside the adjustment hole 19, the gear 20 meshing with the toothed groove 18, an adjustment component inside the rotating ring 4 for adjusting the position of the two extrusion blocks 5, and a positioning component on the top surface of the placement plate 1 for positioning the mounting plate 2. The system incorporates a rotating ring 4. When the worker places the metal material to be welded inside the two rotating rings 4, the position of the two pressing blocks 5 is adjusted using an adjusting component. This allows the two pressing blocks 5 to work together to clamp and fix the metal material inside the rotating rings 4. A positioning component is used to position the two mounting plates 2, controlling their position on the top surface of the placement plate 1. This ensures that the areas where the two metal materials need to be welded are close together, facilitating subsequent welding. A gear 20, rotating inside the adjusting hole 19, drives the rotating rings 4 to rotate, adjusting the angle of the metal material. This facilitates welding of unwelded areas, improving welding efficiency and allowing for welding of different locations on the metal material. A collection box 7 collects the metal debris generated during welding when the metal material is welded at the center of the top surface of the placement plate 1, allowing the debris to fall downwards under its own weight.

[0026] The adjusting component includes several mounting slots 8, all of which are opened on the inner wall of the rotating ring 4. A cylinder 9 is fixedly connected inside the mounting slot 8. Two connecting plates 10 are provided inside the rotating ring 4. The top surface of the connecting plate 10 is fixedly connected to the bottom surface of the telescopic shaft of the two cylinders 9. A connector is provided on the bottom surface of the extrusion block 5 for connecting the extrusion block 5 to the connecting plate 10. In this design, by setting up cylinder 9, when the telescopic shaft of cylinder 9 drives the connecting plate 10 to move, the connecting plate 10 can drive the pressing block 5 to move when it moves by connecting the pressing block 5, so as to facilitate the control of the distance between the two pressing blocks 5, thereby fixing metal materials of different sizes and thicknesses inside the rotating ring 4.

[0027] The connector includes two connecting blocks 11, both of which are fixedly connected to the bottom surface of the extrusion block 5. Two connecting holes 12 are opened on one side of the connecting plate 10. The connecting blocks 11 are movably fitted together with the connecting holes 12. A fixing hole 13 is opened on the top surface of the connecting plate 10. By setting the connecting block 11, since the connecting block 11 and the connecting hole 12 are movably fitted together, the extrusion block 5 can be fixed on the top surface of the connecting plate 10. At the same time, it is convenient to replace the extrusion block 5 of different sizes later and fix metal materials of different shapes.

[0028] Bolt 14 is movably fitted inside the fixing hole 13. Rotating groove 15 is opened on the bottom surface of the extrusion block 5. Thread is provided on the inner wall of the rotating groove 15. Bolt 14 is threaded together with the rotating groove 15. Limiting groove 16 is opened on the inner wall of the placement hole 3. Limiting ring 17 is fixedly connected to the outer wall of the rotating ring 4. Limiting ring 17 is rotatably installed together with limiting groove 16. By setting bolt 14 and threading bolt 14 to rotating groove 15, the extrusion block 5 can be fixed together with the connecting plate 10, which facilitates the later fixing of the extrusion block 5. Since the limiting ring 17 is movably sleeved with the limiting groove 16, the limiting ring 17 can limit the rotating ring 4, thereby preventing the rotating ring 4 from moving out of the placement hole 3.

[0029] A drive motor 21 is fixedly connected to the top surface of the mounting plate 2. The drive motor 21 is a motor with a reducer, and one end of the drive shaft of the drive motor 21 is fixedly connected to one end of the gear 20. By setting up a drive motor 21 and controlling two drive motors 21 to work simultaneously, the two gears 20 can synchronously drive the two rotating rings 4 to rotate, thereby adjusting the angle of the metal material fixed inside the rotating rings 4.

[0030] The positioning component includes two adjustment slots 22, both of which are opened on the top surface of the placement plate 1. An adjustment block 23 is fixedly connected to the bottom surface of the mounting plate 2. The adjustment block 23 is slidably installed with the adjustment slots 22. A rotating hole 24 is opened on one side of the adjustment block 23. The inner wall of the rotating hole 24 is threaded. An adjustment component is provided inside the rotating hole 24 for adjusting the position of the adjustment block 23. By setting an adjustment block 23, and after the adjustment block 23 is movably fitted together with the adjustment groove 22, the mounting plate 2 can move on the top surface of the placement plate 1. At the same time, by using the adjustment component to adjust the position of the adjustment block 23 inside the adjustment groove 22, it is convenient to adjust the position of the two mounting plates 2 on the top surface of the placement plate 1 later.

[0031] The adjusting component includes a lead screw 25, which is threaded into the interior of the rotating hole 24. A motor slot 26 is provided on one side of the interior of the adjusting groove 22. A stepper motor 27 is fixedly connected inside the motor slot 26. One end of the drive shaft of the stepper motor 27 is fixedly connected to one end of the lead screw 25. A fixing slot 28 is provided on one side of the interior of the adjusting groove 22. One end of the lead screw 25 is rotatably mounted to the fixing slot 28. Among them, by setting a stepper motor 27, when the drive shaft of the stepper motor 27 drives the lead screw 25 to rotate, the adjustment block 23 can move inside the adjustment groove 22. When the adjustment block 23 moves, it can drive the mounting plate 2 to move, thereby facilitating the later adjustment of the position of the mounting plate 2 on the top surface of the placement plate 1.

[0032] Sliding grooves 29 are provided on both the left and right sides of the placement plate 1. Limiting plates 30 are fixedly connected to both the left and right sides of the mounting plate 2. A sliding block 31 is fixedly connected to one side of the limiting plate 30. The sliding block 31 is slidably installed together with the sliding groove 29. Among them, by setting the limiting plate 30, since the sliding block 31 and the sliding groove 29 are slidably installed together, the limiting plate 30 can limit the mounting plate 2, thereby reducing the shaking of the mounting plate 2 on the top surface of the placement plate 1.

[0033] In use, by setting up rotating rings 4, after the workers place the metal materials to be welded into the two rotating rings 4 respectively, the positions of the two pressing blocks 5 are adjusted by the adjusting component, so that the two pressing blocks 5 work together to clamp and fix the metal materials inside the rotating rings 4. By using the positioning component to position the two mounting plates 2, the position of the two mounting plates 2 on the top surface of the placement plate 1 is controlled, so that the two metal materials to be welded can fit together, which facilitates the subsequent welding of the metal materials. By setting up gear 20, when gear 20 rotates in the adjusting hole 19, gear 20 can drive rotating ring 4 to rotate, thereby adjusting the angle of the metal materials, which facilitates the subsequent welding of the unwelded parts of the metal materials, thereby improving the welding efficiency of the metal materials and facilitating the subsequent welding of different positions of the metal materials. By setting up collection box 7, when the metal materials are welded at the center position of the top surface of the placement plate 1, the metal debris generated during welding falls down under its own gravity, and collection box 7 can collect the falling metal debris. By setting cylinder 9, when the telescopic shaft of cylinder 9 drives the connecting plate 10 to move, the connecting block 11 and the connecting hole 12 are movably fitted together, so that the extrusion block 5 can be fixed on the top surface of the connecting plate 10. At this time, the moving connecting plate 10 can drive the extrusion block 5 to move, thereby making it easier to control the distance between the two extrusion blocks 5, so as to fix metal materials of different sizes and thicknesses inside the rotating ring 4. Since the limiting ring 17 and the limiting groove 16 are movably fitted together, the limiting ring 17 can limit the rotating ring 4, thereby preventing rotation. Ring 4 is moved out of the placement hole 3. By setting a drive motor 21 and controlling two drive motors 21 to work simultaneously, two gears 20 can synchronously drive two rotating rings 4 to rotate, thereby adjusting the angle of the metal material fixed inside the rotating ring 4. By setting a stepper motor 27, when the drive shaft of the stepper motor 27 drives the lead screw 25 to rotate, the adjusting block 23 can move inside the adjusting groove 22. When the adjusting block 23 moves, it can drive the mounting plate 2 to move, thereby facilitating the later adjustment of the position of the mounting plate 2 on the top surface of the placement plate 1.

[0034] The above embodiments only illustrate one or more implementation methods of this invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these all fall within the protection scope of this invention. Therefore, the protection scope of this invention should be determined by the appended claims.
