Technical Field

[0001] This invention relates to the field of automotive component welding technology, specifically to a high-frequency welding device for automotive parts. Background Technology

[0002] In automobile manufacturing, welding production is characterized by large batch sizes, high production speeds, and high precision requirements for the assembly and welding of parts. It often adopts assembly line production methods, and different parts require different welding methods.

[0003] The traditional welding method involves workers placing the parts to be welded on an operating table, where a welding robot welds them. After welding, the welded car parts are removed, and the above operation is repeated to obtain several welded car parts.

[0004] However, this type of welding equipment has the problem that the welding robot can only be welded after the car parts are placed in place, and the welding robot stops working during the process of placing the car parts, which affects production efficiency. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a high-frequency welding device for automotive parts, which solves the problem of long downtime and reduced production efficiency caused by existing welding robots waiting for automotive parts to be installed and fixed.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a high-frequency welding equipment for automotive parts, comprising a frame, a welding worktable fixed on the frame, a through hole through the welding worktable, a welding robot fixed on the upper surface of the welding worktable and located beside the through hole, and C-shaped protective plates fixed on the front and rear sides of the inner cavity wall of the through hole, with oppositely arranged protective plates on both sides, and a plurality of base plates evenly arranged in the vertical direction between the two protective plates, the protective plates and each base plate being connected by a support assembly, and automotive parts for the welding robot to work on each of the base plates.

[0009] With the above technical solution, each car part to be welded is fixed on a base plate. Several base plates are evenly arranged in the vertical direction and located between two guard plates. The guard plates and base plates are connected by a support component. The welding robot performs welding work on the car part located at the top. After the car part is welded, it is removed. The welding robot can then weld the car parts fixed on the next base plate, reducing the welding robot's downtime and improving welding efficiency.

[0010] Preferably, the support assembly includes a first long shaft disposed within the protective plate, both ends of which are rotatably connected to the inner cavity wall of the protective plate. A support plate, which is fixedly connected to the first long shaft, is nested outside the first long shaft. One end of the support plate extends below the bottom plate, and a second long shaft is disposed above the other end. Both ends of the second long shaft are fixed to the inner cavity wall of the protective plate, and the upper surface of the support plate abuts against the second long shaft.

[0011] With the above technical solution, when the base plate overlaps the upper surface of the two support plates, the first long axis of the integrated structure and the limiting plate will not rotate under the limiting action of the second long axis, and the support plate supports the base plate and the automotive parts to be welded on the base plate.

[0012] Preferably, the upper surface of the support plate has a groove that matches the base plate, and the base plate is attached to the support plate through the groove.

[0013] By using the above technical solution, grooves are made in the support plate to improve the stability of the connection between the base plate and the support plate, and to reduce the possibility of the base plate coming off the support plate during movement.

[0014] Preferably, each of the base plates has a height-increasing plate fixed to its lower surface, and each of the base plates has a column fixed at one of its four corners on its upper surface. The top of the four columns is higher than the height of the automotive parts on the base plate, and the top of the four columns abuts against the height-increasing plate located above the columns. Neither the columns nor the height-increasing plates contact the support plate.

[0015] With the above technical solution, the vertical base plate is connected by mutually abutting columns and a heightening plate, which facilitates the control of all base plates moving up and down, and the heightening plate will not collide with and damage the car parts on the base plate.

[0016] Preferably, the frame is provided with a movable plate located to the lower left of the two guard plates. The upper surface of the movable plate is provided with a base plate on which the automotive parts to be welded are fixed. The frame is provided with a movable component that controls the movable plate to move under the guard plates and pushes the base plate to move upward.

[0017] Using the above technical solution, the workers place the base plate in a suitable position on the moving plate, then fix the car parts to be welded on the base plate. Power is provided by the moving component to move the moving plate and the base plate. While replenishing materials, the base plate is pushed up to facilitate the car parts to be welded at the top to the welding position.

[0018] Preferably, the moving component includes mounting plates fixed at the four corners of the lower surface of the moving plate, each mounting plate having a first short shaft fixed thereon, wherein two of the first short shafts have rollers nested on their outer circumferential walls and rotatably connected to the first short shafts, a guide plate is fixed to the rear side of the frame, the guide plate has a guide groove extending through it, the guide groove is composed of horizontal and vertical sliding grooves that are interconnected, the rollers extend into the guide groove and are slidably connected to the guide groove, and the frame is provided with a control component for controlling the movement of the moving plate and the rollers.

[0019] Through the above technical solution, the control component provides power to drive the moving plate to move. The movement of the moving plate will drive the mounting plate integrated with the moving plate to move. The movement of the mounting plate will drive the first short shaft integrated with the mounting plate to move. The movement of the first short shaft will drive the roller rotatably connected to the first short shaft to move in the guide groove. When the roller moves in the horizontal slide groove, the moving plate and the bottom plate on the moving plate move towards the guard plate. When the roller moves into the vertical slide groove and moves upward in the vertical slide groove, it pushes the bottom plate on the moving plate to move upward into the guard plate.

[0020] Preferably, the control component includes a movable frame disposed below the movable plate, with a second short shaft fixed at each of the four corners of the movable frame. A connecting rod rotatably connected to the second short shaft is nested on the second short shaft. The end of the connecting rod away from the second short shaft is nested outside the first short shaft and rotatably connected to the first short shaft. The frame is provided with a guide component that guides the movement of the movable frame.

[0021] Through the above technical solution, the movement of the movable frame will drive the second short shaft integrated with the movable frame to move. The movement of the second short shaft will push the connecting rod to move, which in turn will drive the first short shaft rotatably connected to the connecting rod to move, thereby causing the roller to slide in the guide groove. When the roller moves into the vertical slide groove, it will push the movable plate to move upward.

[0022] Preferably, the guide assembly includes slide rails fixed on the front and rear sides of the frame, a slider slidably connected to the slide rails, the slider extending out of the slide rails, one end of the second short shaft passing through the movable frame and fixed to the movable frame, and the portion of the slider extending out of the slide rails being fixed to the portion of the second short shaft passing through the movable frame.

[0023] The above technical solution guides the movement of the device through the cooperation of the slider and the slide rail.

[0024] Preferably, the frame is equipped with a power unit for controlling the movement of the mobile frame.

[0025] The above technical solution provides power through a power component, which drives the moving frame to move, and in turn drives the moving plate to move.

[0026] Preferably, the power assembly includes a rack fixed on a movable frame, the long side of the rack being parallel to the moving direction of the movable frame, a drive shaft located below the movable frame being rotatably connected to the frame, a gear coaxially fixed to the drive shaft being nested outside the drive shaft, the gear meshing with the rack, and a motor for controlling the rotation of the drive shaft being fixed on the frame.

[0027] Through the above technical solution, the motor provides power to drive the transmission shaft, which is fixed coaxially with the output shaft of the motor, to rotate. The rotation of the transmission shaft will drive the gear fixed to the transmission shaft to rotate. The rotation of the gear will drive the rack meshing with the gear to move. The movement of the rack will drive the moving frame fixed to the rack to move.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] like Figure 1-8 As shown, the present invention provides a technical solution: a high-frequency welding equipment for automotive parts, including a frame 1, a welding workbench 2 fixed on the frame 1, a through hole 3 through the welding workbench 2, a welding robot 4 fixed on the upper surface of the welding workbench 2 located next to the through hole 3, and a gripping robot 5 provided on the top of the frame 1. The welding robot 4 and the gripping robot 5 are existing structures, so they will not be described in detail here.

[0043] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 The inner wall of the through hole 3 has C-shaped guard plates 6 fixed on both the front and rear sides. The guard plates 6 are axially arranged. Between the two guard plates 6, there are several base plates 7 evenly arranged in the vertical direction. The guard plates 6 and each base plate 7 are connected by a support component 8. Each base plate 7 has a car part 9 for the welding robot 4 to work on, which can be detachably fixed by a quick clamp.

[0044] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 Each automotive component 9 to be welded is fixed on a base plate 7. Several base plates 7 are evenly arranged vertically and located between two guard plates 6. The guard plates 6 and the base plates 7 are connected by a support assembly 8. The welding robot 4 performs welding work on the automotive component 9 located at the top. After the welding is completed, the automotive component 9 is removed, and the welding robot 4 can then weld the automotive component 9 fixed on the next base plate 7, reducing the downtime of the welding robot 4 and improving welding efficiency.

[0045] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 The support assembly 8 includes a first long shaft 801 disposed within the guard plate 6. Both ends of the first long shaft 801 are rotatably connected to the inner cavity wall of the guard plate 6. A support plate 802, which is fixedly connected to the first long shaft 801, is nested outside the first long shaft 801. One end of the support plate 802 extends below the bottom plate 7, and a second long shaft 803 is disposed above the other end. Both ends of the second long shaft 803 are fixed to the inner cavity wall of the guard plate 6. The upper surface of the support plate 802 abuts against the second long shaft 803. The support plate 802 and the guard plate 6 are connected by a torsion spring. When the bottom plate 7 overlaps the upper surfaces of the two support plates 802, the integrated structure of the first long shaft 801 and the limiting plate will not rotate under the limiting action of the second long shaft 803. The support plate 802 supports the bottom plate 7 and the automotive parts 9 to be welded on the bottom plate 7.

[0046] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 The upper surface of the support plate 802 is provided with a groove 804 that is adapted to the base plate 7. The base plate 7 overlaps the support plate 802 through the groove 804. By providing the groove 804 on the support plate 802, the stability of the connection between the base plate 7 and the support plate 802 is improved, and the possibility of the base plate 7 coming off the support plate 802 during movement is reduced.

[0047] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5Each base plate 7 has a raised plate 805 fixed to its lower surface, and each base plate 7 has a column 806 fixed at one of its four corners on its upper surface. The top of the four columns 806 is higher than the height of the car parts 9 on the base plate 7. The top of the four columns 806 abuts against the raised plate 805 located above the column 806. Neither the column 806 nor the raised plate 805 contacts the support plate 802. The base plates 7 in the vertical direction are connected by the mutually abutting columns 806 and raised plates 805, which facilitates the control of all base plates 7 moving upward, and the raised plate 805 will not collide with or damage the car parts 9 on the base plate 7.

[0048] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 In order to further improve the stability of the connection between the base plates 7, the riser plate 805 is provided with several cylindrical slots that are compatible with the column 806. The column 806 and the riser plate 805 located above the column 806 are connected by inserting the cylindrical slots, which improves the stability of the connection without affecting the disassembly and assembly of the base plates 7.

[0049] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 7 and Figure 8 The frame 1 is equipped with a movable plate 10 located to the lower left of the two guard plates 6. The upper surface of the movable plate 10 is covered with a base plate 7 on which the automotive part 9 to be welded is fixed. The frame 1 is equipped with a movable component 11 that controls the movable plate 10 to move under the guard plate 6 and pushes the base plate 7 upward. The operator places the base plate 7 in a suitable position on the movable plate 10, and then fixes the automotive part 9 to be welded on the base plate 7. The movable component 11 provides power to move the movable plate 10 and the base plate 7. While replenishing the material, it pushes the base plate 7 upward, making it easier for the automotive part 9 to be welded at the top to be welded to the welding position.

[0050] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 7 and Figure 8 To improve the stability of the connection between the movable plate 10 and the base plate 7, four positioning posts adapted to the cylindrical slots are fixed on the movable plate 10. The movable plate 10 and the height-increasing plate 805 are connected through the positioning posts and the cylindrical slots. The diameter of the cylindrical slots is larger than the diameter of the positioning posts. The height-increasing plate 805 and the base plate 7 are positioned through the positioning posts and the cylindrical slots without affecting the movement of the height-increasing plate 805 and the base plate 7.

[0051] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 7 and Figure 8 The moving component 11 includes mounting plates 1101 fixed at the four corners of the lower surface of the moving plate 10. Each mounting plate 1101 is fixed with a first short shaft 1102. The outer circumferential walls of two of the first short shafts 1102 are nested with rollers 1103 that are rotatably connected to the first short shafts 1102. A guide plate 1104 is fixed to the rear side of the frame 1. A guide groove 1105 is passed through the guide plate 1104. The guide groove 1105 is composed of a horizontal slide groove 1105-1 and a vertical slide groove 1105-2 that are interconnected. The rollers 1103 extend into the guide groove 1105 and are slidably connected to the guide groove 1105. The frame 1 is provided with a control component for controlling the movement of the moving plate 10 and the rollers 1103.

[0052] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 7 and Figure 8 Power is provided by the control component to drive the movable plate 10 to move. The movement of the movable plate 10 will drive the mounting plate 1101 integrated with the movable plate 10 to move. The movement of the mounting plate 1101 will drive the first short shaft 1102 integrated with the mounting plate 1101 to move. The movement of the first short shaft 1102 will drive the roller 1103 rotatably connected to the first short shaft 1102 to move in the guide groove 1105. When the roller 1103 moves in the horizontal slide groove 1105-1, the movable plate 10 and the bottom plate 7 on the movable plate 10 move toward the guard plate 6. When the roller 1103 moves into the vertical slide groove 1105-2 and moves upward in the vertical slide groove 1105-2, it pushes the bottom plate 7 on the movable plate 10 to move upward into the guard plate 6.

[0053] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 7 and Figure 8The control component includes a movable frame 1106 disposed below the movable plate 10. A second short shaft 1107 is fixed at each of the four corners of the movable frame 1106. A connecting rod 1108, rotatably connected to the second short shaft 1107, is nested on the second short shaft 1107. One end of the connecting rod 1108, away from the second short shaft 1107, is nested outside and rotatably connected to the first short shaft 1102. A guide component is provided on the frame 1 to guide the movement of the movable frame 1106. The movement of the movable frame 1106 will drive the second short shaft 1107, which is integrally formed with the movable frame 1106, to move. The movement of the second short shaft 1107 will push the connecting rod 1108 to move, thereby driving the first short shaft 1102, rotatably connected to the connecting rod 1108, to move. This will cause the roller 1103 to slide within the guide groove 1105. When the roller 1103 moves into the vertical slide groove 1105-2, it will push the movable plate 10 upwards.

[0054] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 7 and Figure 8 The guiding assembly includes slide rails 1109 fixed on the front and rear sides of the frame 1. A slider 1110 is slidably connected to the slide rails 1109. The slider 1110 extends out of the slide rails 1109. One end of the second short shaft 1107 passes through the movable frame 1106 and is fixed to the movable frame 1106. The part of the slider 1110 extending out of the slide rails 1109 is fixed to the part of the second short shaft 1107 passing through the movable frame 1106. Through the cooperation of the slider 1110 and the slide rails 1109, the movement of the device is guided.

[0055] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 7 and Figure 8 The frame 1 is equipped with a power assembly that controls the movement of the movable frame 1106. The power assembly provides power to drive the movable frame 1106 to move, which in turn drives the movable plate 10 to move.

[0056] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 7 and Figure 8The power assembly includes a rack 1111 fixed on a movable frame 1106, with the long side of the rack 1111 parallel to the moving direction of the movable frame 1106. A drive shaft 1113 located below the movable frame 1106 is rotatably connected to the frame 1. A gear 1112 coaxially fixed to the drive shaft 1113 is nested outside the drive shaft 1113. The gear 1112 meshes with the rack 1111. A motor that controls the rotation of the drive shaft 1113 is fixed on the frame 1. The motor provides power to drive the drive shaft 1113, which is coaxially fixed to the output shaft of the motor, to rotate. The rotation of the drive shaft 1113 will drive the gear 1112, which is fixed to the drive shaft 1113, to rotate. The rotation of the gear 1112 will drive the rack 1111, which meshes with the gear 1112, to move. The movement of the rack 1111 will drive the movable frame 1106, which is fixed to the rack 1111, to move.

[0057] When in use, connect the power supply and turn on the switch. The operator is positioned next to the mobile frame 1106. Take a base plate 7 and place it on the mobile plate 10, so that the raising plate 805 of the base plate 7 is connected to the positioning post of the mobile plate 10 through the column slot, so as to position the base plate 7. Then place the car part 9 to be welded on the base plate 7 and fix the car part 9 to be welded by the quick clamp on the base plate 7.

[0058] After the automotive part 9 to be welded is fixed, the motor is turned on, providing power to rotate the transmission shaft 1113, which is coaxially fixed to the motor output shaft. The rotation of the transmission shaft 1113 will drive the gear 1112, which is coaxially fixed to the transmission shaft 1113, to rotate. The rotation of the gear 1112 will drive the rack 1111, which meshes with the gear 1112, to move. The movement of the rack 1111 will drive the moving frame 1106, which is fixed to the rack 1111, to move. The movement of the moving frame 1106 will drive the second short shaft 1107, which is fixed to the moving frame 1106, to move. The movement of the second short shaft 1107 will drive the slider, which is fixed to the second short shaft 1107, to move. 1110 moves, and slider 1110 moves on slide rail 1109. Through the cooperation of slider 1110 and slide rail 1109, the movement of moving frame 1106 is guided and limited. The movement of second short shaft 1107 will drive the connecting rod 1108 movably connected to second short shaft 1107 to move. The movement of connecting rod 1108 will drive the first short shaft 1102 movably connected to connecting rod 1108 to move. The movement of first short shaft 1102 will drive the roller 1103 rotatably connected to first short shaft 1102 to move in guide groove 1105. At the same time, it will drive the mounting plate 1101 and moving plate 10 fixed to first short shaft 1102 to move.

[0059] When the roller 1103 moves in the horizontal slide 1105-1, the moving plate 10 moves in the horizontal direction toward the guard plate 6. When the bottom plate 7 on the moving plate 10 moves below the two guard plates 6, the roller 1103 moves to the bottom of the vertical slide 1105-2. At this time, the moving frame 1106 continues to move, pushing the roller 1103 to move upward in the vertical slide 1105-2, which in turn drives the moving plate 10 to move upward. The moving plate 10 moves upward and drives the bottom plate 7 on the moving plate 10 to move toward the two guard plates 6.

[0060] When the base plate 7 on the movable plate 10 moves into the two guard plates 6, the base plate 7 extends out to the front and rear sides of the heightening plate 805 and moves upward, pushing the support plate 802 to rotate around the first long axis 801 until the base plate 7 moves to the point where it is disconnected from the support plate 802. At this time, the movable plate 10 still does not contact the bottom end of the guard plate 6, the support plate 802 is not interfered with by external force, the torsion spring rebounds, and drives the support plate 802 to rotate to the initial position, and the upper surface of the support plate 802 abuts against the second long axis 803.

[0061] At this time, the control motor drives the transmission shaft 1113 to reverse, the gear 1112 to reverse, the moving frame 1106 moves in the opposite direction, and drives the moving plate 10 to move down until the bottom plate 7 and the support plate 802 come into contact. At this time, the support plate 802 supports the bottom plate 7 under the action of the second long shaft 803, the bottom plate 7 and the moving plate 10 are disconnected, and the moving plate 10 returns to its original position.

[0062] Repeat the above operation, then move the base plate 7 of the other fixed car component 9 below the guard plate 6. The moving plate 10 moves upward, causing the base plate 7 to move upward as well. The upward movement of the base plate 7 causes the column 806 on the base plate 7 to insert into the columnar slot of the riser plate 805 located above the base plate 7. The movement of the base plate 7 will cause the base plate 7 above it to move. At this time, the base plate 7 moves to connect with the bottommost support plate 802, and the base plate 7 above it connects with the uppermost support plate 802. Repeat the above operation until the base plate 7 is connected with the topmost support plate 802. At this time, turn on the welding robot 4 and use the welding robot 4 to weld the base plate 7. The automotive component 9 on plate 7 is welded. After welding, the gripping robot 5 removes the base plate 7 and the welded automotive component 9 from the base plate 7. At the same time, the moving plate 10 moves again, moving the fixed automotive component 9 and its base plate 7 onto the guard plate 6, and pushing another base plate 7 to the position of the topmost support plate 802. This facilitates the welding work of the welding robot 4, shortens the downtime of the welding robot 4, and improves the working efficiency of the welding robot 4. This is the usage process of the high-frequency welding equipment for automotive parts. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.
