Description

Technical Field

[0001] The present application relates to the technical field of friction welding fixtures, and in particular to a friction welding fixture adapted for an electric control box of a new energy vehicle. Background Art

[0002] Friction welding is a method that uses the heat generated by the movement and friction between the end faces of the workpieces to make the ends reach a thermoplastic state, and then quickly forges them to complete the welding. Friction welding can easily connect the same or different materials, including metals, some metal-based composite materials, ceramics and plastics.

[0003] In the processing of electric control boxes for new energy vehicles, friction welding equipment is often used to weld components to the electric control boxes. At present, the industry still generally uses a completely manual operation method to complete the assembly of electric control boxes and components. Workers directly hold tools and align the positions and then fix the screws in sequence to assemble the components of the electric control box.

[0004] However, although this method is highly flexible, it is easy to cause problems such as welding point deviation due to uneven hand grip. Especially when dealing with highly integrated and complex components such as the electric control box of new energy vehicles, how to ensure that each welding can accurately achieve the expected effect has become one of the key problems that need to be solved urgently. Summary of the invention

[0005] In order to improve the accuracy of friction welding, the present application provides a friction welding fixture adapted for an electric control box of a new energy vehicle.

[0008] By adopting the above technical scheme, when the electric control box needs to be friction welded, the electric control box is first placed on the fixture base with the welding station facing upwards, and then the electric control box is pressed and fixed by the box fixing module, and then the parts to be welded are placed on the welding station, and then pressed and fixed by the parts squeezing module, and then the friction welding equipment is started. At this time, the processing end of the friction welding equipment performs friction welding on the parts to be welded, and the parts to be welded are pressed and fixed by the parts squeezing module to prevent the parts to be welded from moving during the friction welding process, and the electric control box is fixed by the box fixing module to prevent the electric control box from shifting during the friction welding process, which is beneficial to improve the accuracy of friction welding.

[0010] By adopting the above technical solution, when the cylinder is started, the telescopic end of the cylinder drives the extrusion rod to swing, and the extrusion rod swings with the hinge rod as the axis. At this time, one end of the extrusion rod presses the part to be welded through the buffer assembly. Similarly, when the cylinder is reset, the extrusion rod is reset and swung with the hinge rod as the axis, thereby releasing the extrusion of the entire electric control box, which is beneficial to improve the stability of the part to be welded fixed in the welding station.

[0012] By adopting the above technical solution, when the extrusion rod swings toward the direction approaching the part to be welded, the extrusion rod drives the extrusion block to squeeze downward. After the extrusion block squeezes the part to be welded, the extrusion block squeezes the first spring inward, thereby buffering and adapting the extrusion force of the extrusion rod to avoid deformation of the part to be welded due to excessive extrusion force.

[0013] Optionally, the box fixing module includes an upper pressure rod and a side pressure rod, the top surface of the base plate is provided with a plurality of fixing seats, the side pressure rod is hingedly arranged on one side of the fixing seat, rotating shafts are symmetrically arranged on both sides of the upper pressure rod, and sliding grooves are symmetrically opened on the inner side of the top surface of the fixing seat, the rotating shafts are rotatably and slidably connected to the sliding grooves, and the fixing seat is provided with a driving mechanism for simultaneously driving the upper pressure rod and the side pressure rod to squeeze and swing.

[0014] By adopting the above technical solution, when the electric control box needs to be fixed, the upper pressure rod is first pushed in the direction close to the electric control box, and then the upper pressure rod and the side pressure rod are simultaneously driven to swing in the direction close to the electric control box through the driving mechanism. The upper pressure rod is used to press the electric control box tightly on the clamp base, and the side pressure rod is used to prevent the electric control box from shifting horizontally, which is beneficial to improving the accuracy of friction welding.

[0016] By adopting the above technical solution, when the cam rotates, the cam drives the upper pressure rod to swing with the rotating shaft as the axis. At this time, the upper pressure rod is pressed against the top surface of the electric control box. While the upper pressure rod is swinging, the upper pressure rod drives the pull rod to rise, and the pull rod then drives the side pressure rod to swing. At this time, the side pressure rod is pressed against the side wall of the electric control box. Similarly, when the cam is reset and rotated, under the action of the reset assembly, the upper pressure rod and the side pressure rod simultaneously release the clamping fixation of the electric control box, which is beneficial to improve the stability of the electric control box fixed on the clamp base.

[0017] Optionally, the reset assembly includes a second spring and a third spring, a lifting groove is opened in the fixed seat, the second spring is arranged in the lifting groove, the second spring is sleeved on the pull rod, one end of the second spring is connected to the side pressure rod, and the other end of the second spring is connected to the inner groove wall of the lifting groove, the third spring is arranged in the fixed seat, the third spring is sleeved on the pull rod, one end of the third spring is connected to the top surface of the fixed seat, and the other end of the third spring is fixedly connected to the side wall of the pull rod.

[0018] By adopting the above technical solution, when the cam finally drives the pull rod to move upward, the side pressure rod squeezes the second spring, and the pull rod stretches the third spring at the same time. When the cam resets and rotates, the second spring and the third spring release their elastic force at the same time, and drive the pull rod to move downward. At this time, the upper pressure rod and the side pressure rod both swing away from the electrical control box, which is beneficial to improve the stability of the swinging and squeezing of the side pressure rod and the upper pressure rod.

[0020] By adopting the above technical solution, the swing amplitude of the upper pressure rod is affected by the radius of the cam. When it is necessary to drive the upper pressure rod to move in a direction away from the electric control box, the upper pressure rod is first unlocked by the fixing member, and then driven to move in a direction away from the electric control box. At this time, the upper pressure rod slides relative to the slider. When it is necessary to fix the position of the upper pressure rod, the slider is fixed in the sliding hole by the fixing member. At this time, the upper pressure rod is fixed by the slider and the pull rod, and the upper pressure rod is fixed in the current position, which is beneficial to improve the stability of the electric control box placed on the fixture base.

[0021] Optionally, the fixing member is a bolt, a side wall of the bolt is sleeved with a gasket, the gasket is arranged on the top surface of the upper pressure rod, a thread groove is opened on the top surface of the sliding block, and the bolt is threadedly connected to the thread groove.

[0022] By adopting the above technical solution, when the bolt is tightened, the gasket is pressed against the top surface of the upper pressure rod, and under the action of friction, the slider is fixed in the slider.

[0023] Optionally, one end of the side pressure rod and the upper pressure rod are both provided with a rubber pad.

[0024] By adopting the above technical solution, under the protection of the rubber pad, it is helpful to prevent the extruded ends of the side pressure rod and the upper pressure rod from causing damage to the electric control box.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] Example:

[0035] See also Figure 1 and Figure 2 A friction welding fixture adapted to the electric control box of a new energy vehicle includes a bottom plate 1, the top surface of the bottom plate 1 is fixedly connected with a fixture base 2, the fixture base 2 is used to carry the electric control box 3, and the electric control box 3 is adapted to the fixture base 2. The electric control box 3 includes a welding surface, the welding surface is provided with a welding station 4, and a component 5 to be welded is placed in the welding station 4, and the component 5 to be welded is welded to the electric control box 3 through a friction welding device. The bottom plate 1 is equipped with a component extrusion module, and the component extrusion module is used to press the component 5 to be welded. The bottom plate 1 is also equipped with a box fixing module, and the box fixing module is used to clamp and fix the electric control box 3, and to center the electric control box 3.

[0036] The friction welding device is used to weld the component 5 to be welded to the electric control box 3. First, the electric control box 3 is placed on the fixture base 2, and the welding station 4 is facing upward. Then the electric control box 3 is fixed to the fixture base 2 by the box fixing module. Then the component 5 to be welded is placed on the welding station 4, and then the component pressing module is used to press and fix the component 5 to be welded in the welding station 4. Then the friction welding device is started, and the processing end of the friction welding device performs friction welding on the component 5 to be welded.

[0037] For details, see Figure 1 and Figure 3The component extrusion module includes a cylinder 6. There are multiple cylinders 6, and the multiple cylinders 6 are respectively fixedly installed on the base plate 1, and the multiple cylinders 6 are evenly distributed along the circumference of the electric control box 3. The cylinder 6 includes a fixed end and a telescopic end. The fixed end of each cylinder 6 is fixedly connected to a support 7, and the two sides of the support 7 are respectively hinged with hinged rods 8, and the inner sides of the two hinged rods 8 are hinged with extrusion rods 9. The telescopic end of the cylinder 6 is hinged to one end of the extrusion rod 9, and the other end of the extrusion rod 9 is an extrusion end.

[0038] When the cylinder 6 is started and the telescopic end of the cylinder 6 is extended, the telescopic end of the cylinder 6 drives the extrusion rod 9 to swing, and the extrusion rod 9 swings around the hinge point of the hinge rod 8 and the support 7 until the extrusion end of the extrusion rod 9 is pressed on the top surface of the part to be welded 5. Conversely, when the telescopic end of the cylinder 6 is shortened, the telescopic end of the cylinder 6 drives the extrusion rod 9 to reset and swing, and the extrusion rod 9 resets and swings around the hinge point of the hinge rod 8 and the support 7 until the extrusion rod 9 completely detaches from the part to be welded 5. After the extrusion rod 9 completely detaches from the part to be welded 5, the extrusion rod 9 is vertically arranged, which is conducive to avoiding collision between the extrusion rod 9 and the friction welding equipment.

[0039] See also Figure 3 In order to prevent the extrusion end of the extrusion rod 9 from damaging the to-be-welded component 5 and causing deformation of the to-be-welded component 5, a buffer assembly is installed at the extrusion end of the extrusion rod 9, and the buffer assembly includes an extrusion block 10 and a first spring 11. A buffer groove 12 is provided at the extrusion end of the extrusion rod 9, and the extrusion block 10 is slidably disposed in the buffer groove 12. The first spring 11 is installed in the buffer groove 12, and one end of the first spring 11 is fixedly connected to the top surface of the extrusion block 10, and the other end of the first spring 11 is fixedly connected to the groove top wall of the buffer groove 12.

[0040] When the extrusion end of the extrusion rod 9 swings toward the direction close to the component to be welded 5, the extrusion block 10 first squeezes the top surface of the component to be welded 5 and squeezes the first spring 11. Under the action of the first spring 11, it is helpful to make the component to be welded 5 adapt to the extrusion force in advance, thereby avoiding deformation caused by the instantaneous excessive extrusion force.

[0041] For details, see Figure 1 and Figure 4 The box fixing module includes an upper pressure rod 13 and a side pressure rod 14. A plurality of cushion seats 15 are fixedly installed on the top surface of the bottom plate 1. The plurality of cushion seats 15 are evenly distributed on the peripheral side of the electric control box 3, and a fixing seat 16 is fixedly connected to the top surface of each cushion seat 15. The side pressure rod 14 is in a Z shape, and the side pressure rod 14 is hinged to one side of the fixing seat 16. The two sides of the upper pressure rod 13 are symmetrically fixedly connected with a rotating shaft 17, and the rotating shaft 17 is cylindrical. The inner side of the top surface of the fixing seat 16 is symmetrically provided with a slide groove 18, and the rotating shafts 17 on both sides rotate and slide in the slide groove 18 respectively.

[0042] See also Figure 4 In order to facilitate the simultaneous swinging of the upper pressure rod 13 and the side pressure rod 14, and to squeeze and limit the electric control box 3, the fixed seat 16 is equipped with a driving mechanism. The driving mechanism includes a pull rod 19 and a cam 20. The cam 20 is rotatably installed on the side of the fixed seat 16 away from the side pressure rod 14. The upper pressure rod 13 also includes an extrusion end and a swing end, and the surface of the cam 20 abuts against the swing end of the upper pressure rod 13. The pull rod 19 is lifted and installed in the fixed seat 16, and the top end of the pull rod 19 slides and is hinged with the upper pressure rod 13, and the bottom end of the pull rod 19 is hinged with the side pressure rod 14.

[0043] See also Figure 4 In order to cooperate with the reset swing of the upper pressure rod 13 and the side pressure rod 14, the fixed seat 16 is also equipped with a reset assembly, which includes a second spring 21 and a third spring 22. A lifting groove 23 is provided in the fixed seat 16, and the second spring 21 is installed in the lifting groove 23. The second spring 21 is sleeved on the pull rod 19, and one end of the second spring 21 is fixedly connected to the top surface of the side pressure rod 14, and the other end of the second spring 21 is fixedly connected to the groove top wall of the lifting groove 23. The third spring 22 is arranged in the fixed seat 16, and the third spring 22 is also sleeved on the pull rod 19, and one end of the third spring 22 is fixedly connected to the side wall of the pull rod 19, and the other end of the third spring 22 is fixedly connected to the inner top surface of the fixed seat 16.

[0044] When the cam 20 rotates and the protruding surface of the cam 20 abuts against the swinging end of the upper pressure rod 13, the upper pressure rod 13 swings toward the direction close to the electric control box 3 with the rotating shafts 17 on both sides as the axis, and the extrusion end of the upper pressure rod 13 squeezes the top surface of the electric control box 3. During the extrusion and swinging process of the upper pressure rod 13, the upper pressure rod 13 drives the pull rod 19 to rise, and the pull rod 19 then drives the side pressure rod 14 to swing toward the direction close to the electric control box 3, and the side pressure rod 14 squeezes the side wall of the electric control box 3. It should be noted that during the rising process of the pull rod 19, the side pressure rod 14 squeezes the second spring 21, and the pull rod 19 stretches the third spring 22.

[0045] The plurality of side pressure rods 14 together squeeze and fix the side wall of the electric control box 3, which is conducive to centering the electric control box 3. The plurality of upper pressure rods 13 together squeeze and fix the top surface of the electric control box 3, which is conducive to tightly fixing the electric control box 3 on the fixture base 2.

[0046] It is worth mentioning that see Figure 4 The side wall of the cam 20 is fixedly connected with a handle 24, and the handle 24 is fixedly connected to the axis of the cam 20. The cam 20 is driven to rotate by the handle 24, thereby improving the convenience of the cam 20 rotation.

[0047] See also Figure 4 and Figure 5Since the swinging range of the upper pressure rod 13 is limited, it is easy to affect the removal of the electric control box 3 from the fixture base 2. For this reason, a sliding hole 25 is penetrated through the top surface of the upper pressure rod 13, and a slider 26 is slidably installed in the sliding hole 25, and the top of the pull rod 19 is hinged to the bottom surface of the slider 26. A handle 27 is fixedly connected to the top surface of the swinging end of the upper pressure rod 13.

[0048] See also Figure 4 and Figure 5 In order to fix the slider 26 in the slide hole 25 and fix the position of the upper pressure rod 13, the upper pressure rod 13 is provided with a fixing member, which is a bolt 28. The side wall of the bolt 28 is sleeved with a gasket 29, and the gasket 29 abuts against the top surface of the upper pressure rod 13. The top surface of the slider 26 is provided with a thread groove 30, and the fixed end of the bolt 28 is threadedly connected to the thread groove 30.

[0049] When the bolt 28 is tightened, the bolt 28 is pressed against the top surface of the upper pressure rod 13 through the gasket 29. Under the friction force of the gasket 29, the upper pressure rod 13 is connected and fixed with the pull rod 19. Since the horizontal position of the pull rod 19 is limited, the upper pressure rod 13 cannot move in the horizontal direction at this time. When the bolt 28 is loosened, the slider 26 and the upper pressure rod 13 are released from the restriction at the same time, and the upper pressure rod 13 is driven to move in the horizontal direction away from the electric control box 3 through the handle 27, so as to facilitate the electric control box 3 to be taken and placed on the fixture base 2.

[0050] It is worth noting that see Figure 4 In order to prevent the extruded ends of the side pressure rod 14 and the upper pressure rod 13 from damaging the electric control box 3 , the extruded ends of the upper pressure rod 13 and the side pressure rod 14 are fixedly connected with rubber pads 31 .

[0051] Working principle of a friction welding fixture adapted to the electric control box of new energy vehicles:

[0052] Use friction welding equipment to weld the component 5 to the electric control box 3. First, loosen the bolt 28, and then drive the upper pressure rod 13 away from the fixture base 2, then place the electric control box 3 on the fixture base 2, and make the welding station 4 face upward. Then drive the upper pressure rod 13 to move in the direction close to the electric control box 3, and the upper pressure rod 13 moves to the required position according to the actual model of the electric control box 3, and then tighten the bolt 28 to fix the upper pressure rod 13 in the current position. Then, rotate the cam 20 through the handle 24, and lift the swing end of the upper pressure rod 13 upward through the protruding surface of the cam 20. The upper pressure rod 13 swings in the direction close to the electric control box 3 with the rotating shafts 17 on both sides as the axis. At this time, the extrusion end of the upper pressure rod 13 extrudes the top surface of the electric control box 3. During the squeezing and swinging of the upper pressure rod 13, the upper pressure rod 13 drives the pull rod 19 to rise, and the pull rod 19 then drives the side pressure rod 14 to swing toward the direction close to the electric control box 3, and at this time the side pressure rod 14 squeezes the side wall of the electric control box 3. It should be noted that during the rising process of the pull rod 19, the side pressure rod 14 squeezes the second spring 21, and the pull rod 19 stretches the third spring 22. Under the action of the side pressure rod 14 and the upper pressure rod 13, the electric control box 3 is fixed in the center.

[0053] Then, the component 5 to be welded is pre-placed on the welding station 4. After the component 5 to be welded is placed, the cylinder 6 is started and the telescopic end of the cylinder 6 is extended. The telescopic end of the cylinder 6 drives the extrusion rod 9 to swing, and the extrusion rod 9 swings around the hinge point of the hinge rod 8 and the support 7 until the extrusion end of the extrusion rod 9 is pressed on the top surface of the component 5 to be welded. When the extrusion end of the extrusion rod 9 swings toward the direction close to the component 5 to be welded, the extrusion block 10 first presses on the top surface of the component 5 to be welded and compresses the first spring 11. Under the action of the first spring 11, it is helpful to make the component 5 to be welded adapt to the extrusion force in advance, thereby avoiding deformation caused by excessive instantaneous extrusion force.

[0054] After the parts to be welded 5 are pressed, the friction welding device is started, and the friction welding device performs welding along the contour of the parts to be welded 5. It should be emphasized that when the processing end of the friction welding device is close to the extrusion rod 9, the corresponding telescopic end of the cylinder 6 resets and moves, actively making room for the processing end of the friction welding device to maintain processing.

[0055] To summarize, the component to be welded 5 is pressed and fixed by the component extrusion module to prevent the component to be welded 5 from moving during the friction welding process, and the electric control box 3 is limited and fixed by the box fixing module so that the electric control box 3 is centered and fixed on the fixture base 2 to prevent the electric control box 3 from shifting during the friction welding process, which is beneficial to improve the accuracy of friction welding.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
