Description

Technical Field

[0001] The present invention relates to the technical field of welding, and more particularly to a welding device for automotive parts. Background Art

[0002] Welding devices based on the processing of automotive parts are mainly concerned with the connection, combination, strength, and durability requirements of various metal parts during the automotive manufacturing process. Welding technology is a crucial link in the automotive industry and is widely used in body manufacturing, chassis, engine components, exhaust systems, and the production of other key automotive parts.

[0003] Existing welding devices for automotive parts include a clamping structure and a welding processing structure. The clamping structure is installed on the left side of the positioning seat. The clamping structure is specifically composed of a chassis, cross screws, a sleeve, a snap ring, a sliding column, and a pressing plate. The cross screws penetrate through the interior of the chassis. The sleeve is welded to the right side of the chassis. A snap ring is arranged inside the sleeve. The outer surface of the sliding column is fitted with the snap ring. The pressing plate is welded to the right side of the sliding column. This welding device for automotive parts uses the pressing plate to clamp parts. However, when welding the outer surface of some tubular parts, the rapidly rotating welding head exerts a relatively large pressure on the outer surface of the tubular parts, which may cause the parts to bend at a certain angle, thus affecting the overall welding effect of the device. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a welding device for automotive parts, which solves the problems mentioned in the above background art. To achieve the above objectives, the present invention is realized through the following technical solutions: A welding device for automotive parts, including a base, on the top of the base is assembled a rotating table driven by a servo motor. Inside the rotating table is assembled a laser welding head driven by an electric push rod. Inside the base is rotatably connected a through screw rod. A sliding block is threadedly connected to the outside of the screw rod. A clamping seat is assembled on the top of the sliding block. A gear ring is fixedly connected to the outside of the rotating table. A gear is rotatably connected to the side of the base. The side of the gear is drivingly connected to a hydraulic chamber I. A moving block is slidably connected to the inner wall of the hydraulic chamber I through an elastic telescopic rod. An arc-shaped plate is slidably connected to the outside of the hydraulic chamber I. A hydraulic device is assembled between the base and the clamping seat. A force-receiving rod I is slidably connected to the bottom of the hydraulic device. A spring I is assembled on the top of the force-receiving rod I. The side of the hydraulic device is slidably connected to an inner wall support plate. A limiting component for maintaining stability is assembled on the side of the base. A cleaning component for cleaning welding slag is assembled on the top of the base. Through the setting of the device, the possibility of the parts bending can be reduced, and the overall welding effect of the device is improved.

[0005] Preferably, the gear is located on the side of the toothed ring and is in a meshing state with the toothed ring.

[0006] Preferably, one end of the first spring away from the first force-bearing rod is assembled on the inner wall of the first hydraulic chamber.

[0007] Preferably, the limiting assembly includes a second hydraulic chamber. One end of the second hydraulic chamber is slidably connected with a connecting rod, and the other end of the second hydraulic chamber is slidably connected with an elastic telescopic block. A pawl is assembled on the side of the elastic telescopic block, and a ratchet wheel is fixedly connected to the outer side of the lead screw. Through the setting of the limiting assembly, the possibility of the clamping effect deteriorating due to accidental contact with the lead screw during the use of the device is reduced.

[0008] Preferably, the connecting rod is located on the side of the first force-bearing rod and is in a fixed state with the first force-bearing rod.

[0009] Preferably, when the limiting assembly is in an enabled state, the ratchet wheel and the pawl are in a meshing state.

[0010] Preferably, the cleaning assembly includes a third hydraulic chamber. A moving rod driven by an electric telescopic rod is assembled on the top of the base. A cleaning brush is assembled at the bottom of the moving rod. A cam is drivingly connected to the side of the gear. One end of the third hydraulic chamber close to the cam is slidably connected with a second force-bearing rod. A second spring is assembled on the top of the second force-bearing rod. One end of the third hydraulic chamber away from the second force-bearing rod is slidably connected with a pressing plate. The top of the cleaning brush is connected with a force-bearing plate through an elastic telescopic member. Through the setting of the cleaning assembly, the cleaning effect of the cleaning brush on the welding slag on the top of the base can be improved, subsequent cleaning operations are reduced, and the device is made easier to use.

[0011] Preferably, the force-bearing plate is located on the top of the pressing plate and is in contact with the pressing plate.

[0012] The present invention provides a welding device for automotive parts. It has the following beneficial effects: (1) When the welding device for automotive parts performs corresponding welding operations on tubular parts, in cooperation with the toothed ring, gear, first hydraulic chamber, elastic telescopic rod, moving block, arc-shaped plate, hydraulic device, first force-bearing rod and first spring, the inner wall support plate moves towards the side close to the inner wall of the clamp seat, and cooperates with the clamp seat to support the inner wall of the tubular part, reducing the possibility of the part being bent and improving the overall welding effect of the device.

[0013] (2) After the automotive part welding equipment completes the preliminary clamping of the parts, when welding operations are carried out, the first stress rod moves. In cooperation with the second hydraulic chamber, the connecting rod, the elastic telescopic block, the ratchet pawl and the ratchet wheel, the two clamping seats can only move towards each other to further clamp the parts, reducing the possibility that the clamping effect deteriorates due to accidental contact with the lead screw during the use of the device.

[0014] (3) When the automotive part welding equipment performs welding operations, the electric telescopic rod is started to drive the moving rod to reciprocate horizontally. In cooperation with the third hydraulic chamber, the cam, the second stress rod, the second spring, the pressing plate, the elastic telescopic member and the stress plate, the cleaning effect of the cleaning brush on the welding slag on the top of the base can be improved, reducing subsequent cleaning operations and making the device easier to use.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] Example 1, please refer to Figures 1 - 5 , an automotive parts welding device, including a base 100, a rotating table 200 driven by a servo motor is assembled on the top of the base 100, a laser welding head 300 driven by an electric push rod is assembled inside the rotating table 200, a through screw rod 400 is rotatably connected inside the base 100, a sliding block 500 is connected to the outside of the screw rod 400 through a thread, and a clamping seat 600 is assembled on the top of the sliding block 500. Place the tubular part between the two clamping seats 600 to Figure One and Figure Two As shown in, rotate the screw rod 400 clockwise to drive the two sliding blocks 500 and the clamping seats 600 respectively assembled on the two sliding blocks 500 to move towards each other, completing the preliminary clamping of the tubular part. Subsequently, start the servo motor and the electric push rod to drive the rotating table 200 and the laser welding head 300 to rotate, and perform corresponding welding operations on the tubular part; A gear ring 701 is fixedly connected to the outside of the rotating table 200, a gear 702 is rotatably connected to the side of the base 100, the gear 702 is located on the side of the gear ring 701 and is in a meshing state with the gear ring 701, and a first hydraulic chamber 703 is drivingly connected to the side of the gear 702. Perform corresponding welding operations. At this time, the rotating table 200 drives the gear ring 701 fixedly connected thereto to rotate, so that the gear ring 701 drives the gear 702 meshing with it to rotate rapidly, and the gear 702 then drives the first hydraulic chamber 703 drivingly connected to it to rotate rapidly.

[0019] A moving block 705 is slidably connected to the inner wall of the first hydraulic chamber 703 through an elastic telescopic rod 704, and an arc-shaped plate 706 is slidably connected to the outside of the first hydraulic chamber 703. When the first hydraulic chamber 703 rotates rapidly, the moving block 705 in the first hydraulic chamber 703 slides along the inner wall of the first hydraulic chamber 703 by stretching the elastic telescopic rod 704 under the action of centrifugal force, increasing the pressure in the first hydraulic chamber 703 and driving the arc-shaped plate 706 slidably connected to the first hydraulic chamber 703 to move.

[0020] A hydraulic device 707 is assembled between the base 100 and the clamping seat 600. A first force-bearing rod 708 is slidably connected to the bottom of the hydraulic device 707. A first spring 709 is assembled at the top of the first force-bearing rod 708. One end of the first spring 709 away from the first force-bearing rod 708 is assembled on the inner wall of the first hydraulic chamber 703. An inner wall support plate 710 is slidably connected to the side of the hydraulic device 707. While rotating, the arc-shaped plate 706 extends, thereby squeezing the first force-bearing rod 708. Cooperating with the hydraulic device 707 slidably connected to the first force-bearing rod 708, the pressure inside the hydraulic device 707 is increased, driving the inner wall support plate 710 slidably connected to the hydraulic device 707 to move. The inner wall support plate 710 moves towards the side close to the inner wall of the clamping seat 600, cooperating with the clamping seat 600 to support the inner wall of the tubular component. The possibility of the component being bent is reduced, and the overall welding effect of the device is improved.

[0021] After completing the corresponding welding operation, stop the device, so that the rotating table 200 stops rotating. Similarly, stop the first hydraulic chamber 703 from rotating. Under the action of the elastic telescopic rod 704, the moving block 705 can be reset without the action of centrifugal force. Similarly, reset the arc-shaped plate 706. Without the action of the arc-shaped plate 706 on the first force-bearing rod 708, the first force-bearing rod 708 can be reset under the action of the first spring 709, thereby completing the reset of the device. Facilitating the next use of the device.

[0022] A limiting component 800 for maintaining stability is assembled on the side of the base 100, and a cleaning component 900 for cleaning welding slag is assembled on the top of the base 100.

[0023] During use, place the tubular component between the two clamping seats 600 to Figure One and Figure TwoAs shown in the figure, rotate the lead screw 400 clockwise to drive the two sliding blocks 500 and the clamping seats 600 respectively assembled on the two sliding blocks 500 to move towards each other, completing the preliminary clamping of the tubular component. Subsequently, start the servo motor and the electric push rod to drive the rotating table 200 and the laser welding head 300 to rotate, and perform corresponding welding operations on the tubular component. At this time, the rotating table 200 drives the gear ring 701 fixedly connected thereto to rotate, causing the gear ring 701 to drive the gear 702 meshing with it to rotate rapidly. The gear 702 then drives the hydraulic chamber 703 connected to it by transmission to rotate rapidly. The moving block 705 in the hydraulic chamber 703 is then stretched by the elastic telescopic rod 704 and slides along the inner wall of the hydraulic chamber 703 under the action of centrifugal force, increasing the pressure in the hydraulic chamber 703 and driving the arc-shaped plate 706 slidably connected to the hydraulic chamber 703 to move. At this time, the arc-shaped plate 706 extends while rotating, thus squeezing the force-bearing rod 708. Cooperating with the hydraulic device 707 slidably connected to the force-bearing rod 708, the pressure in the hydraulic device 707 is increased, driving the inner wall support plate 710 slidably connected to the hydraulic device 707 to move. The inner wall support plate 710 moves towards the side close to the inner wall of the clamping seat 600 to support the inner wall of the tubular component in cooperation with the clamping seat 600; after completing the corresponding welding operation, stop the device, causing the rotating table 200 to stop rotating. Similarly, cause the hydraulic chamber 703 to stop rotating. When the moving block 705 loses the action of centrifugal force, it can be reset under the action of the elastic telescopic rod 704. Similarly, cause the arc-shaped plate 706 to be reset. The force-bearing rod 708 loses the action of the arc-shaped plate 706 and can be reset under the action of the spring 709, thus causing the device to complete the reset.

[0024] Embodiment 2. Please refer to Figures 1 - 6 , on the basis of Embodiment 1, the limiting component 800 includes a hydraulic chamber 801. One end of the hydraulic chamber 801 is slidably connected with a connecting rod 802. The connecting rod 802 is located on the side of the force-bearing rod 708 and is in a fixed state with the force-bearing rod 708. The other end of the hydraulic chamber 801 is slidably connected with an elastic telescopic block 803. After completing the preliminary clamping of the component, when performing the welding operation, the force-bearing rod 708 moves, causing the force-bearing rod 708 to drive the connecting rod 802 fixedly connected thereto to move upward. Cooperating with the hydraulic chamber 801 slidably connected to the connecting rod 802, the pressure in the hydraulic chamber 801 is increased, driving the elastic telescopic block 803 slidably connected to the hydraulic chamber 801 to move laterally.

[0025] A pawl 804 is assembled on the side of the elastic expansion block 803, and a ratchet 805 is fixedly connected to the outer side of the lead screw 400. When the limiting component 800 is in the enabled state, the ratchet 805 and the pawl 804 are in an engaged state. When the elastic expansion block 803 moves laterally, the elastic expansion block 803 immediately drives the pawl 804 assembled on its side to move laterally, and the pawl 804 then moves to the ratchet 805 on the lead screw 400, and the lead screw 400 is restricted to a certain extent through the ratchet 805. At this time, the pawl 804 used in conjunction with the elastic expansion block 803 restricts the ratchet 805 and the lead screw 400 to only rotate clockwise in this case, that is, only the two clamping seats 600 can move towards each other to further clamp the components, while the ratchet 805 and the lead screw 400 cannot rotate counterclockwise in this case, resulting in a poor clamping effect of the clamping seat 600 on the components. In this way, the possibility of the clamping effect deteriorating due to accidental contact with the lead screw 400 during the use of the device can be reduced.

[0026] After welding is completed and the device is deactivated, when the force-bearing rod one 708 is reset under the action of the spring one 709, the connecting rod 802 fixedly connected to the force-bearing rod one 708 is reset synchronously, so that the limiting component 800 is reset. This facilitates the next activation of the limiting component 800.

[0027] During use, on the basis of Embodiment 1, after the preliminary clamping of the components is completed and welding operation is carried out, the force-bearing rod one 708 moves, causing the force-bearing rod one 708 to drive the connecting rod 802 fixedly connected to it to move upward. In cooperation with the hydraulic chamber two 801 slidably connected to the connecting rod 802, the pressure in the hydraulic chamber two 801 increases, driving the elastic expansion block 803 slidably connected to the hydraulic chamber two 801 to move laterally. The elastic expansion block 803 immediately drives the pawl 804 assembled on its side to move laterally, and the pawl 804 then moves to the ratchet 805 on the lead screw 400, and the lead screw 400 is restricted to a certain extent through the ratchet 805. At this time, the pawl 804 used in conjunction with the elastic expansion block 803 restricts the ratchet 805 and the lead screw 400 to only rotate clockwise in this case, that is, only the two clamping seats 600 can move towards each other to further clamp the components, while the ratchet 805 and the lead screw 400 cannot rotate counterclockwise in this case, resulting in a poor clamping effect of the clamping seat 600 on the components. After welding is completed and the device is deactivated, when the force-bearing rod one 708 is reset under the action of the spring one 709, the connecting rod 802 fixedly connected to the force-bearing rod one 708 is reset synchronously, so that the limiting component 800 is reset.

[0028] Embodiment 3, please refer to Figures 1 - 8On the basis of the first and second embodiments, the cleaning assembly 900 includes a hydraulic chamber 3 901, a moving rod 902 driven by an electric telescopic rod is mounted on the top of the base 100, and a cleaning brush 903 is mounted on the bottom of the moving rod 902. When welding, the electric telescopic rod is started to drive the moving rod 902 driven by the electric telescopic rod to reciprocate in the horizontal direction, and the moving rod 902 then drives the cleaning brush 903 mounted at its bottom to reciprocate on the top of the base 100, sweeping the welding slag on the top of the base 100 from the opening at the top of the base 100 into the base 100.

[0029] The side of the gear 702 is connected to the cam 904 in a transmission manner, and the end of the hydraulic chamber 3 901 close to the cam 904 is slidably connected to the force rod 2 905, and the top of the force rod 2 905 is equipped with a spring 2 906. During the welding operation, the fast-rotating gear 702 drives the cam 904 connected thereto to rotate, and when the protruding part of the cam 904 rotates to the force rod 2 905, the force rod 2 905 can be squeezed to compress the spring 2 906 and move upward, and when the protruding part of the cam 904 continues to rotate away from the force rod 2 905, the force rod 2 905 can be reset under the action of the spring 2 906, so that the force rod 2 905 can be reciprocated in the vertical direction.

[0030] The end of the hydraulic chamber 3 901 away from the stress rod 2 905 is slidably connected with a pressure plate 907. The top of the cleaning brush 903 is connected with a stress plate 909 by setting an elastic telescopic member 908. The stress plate 909 is located at the top of the stress plate 907 and is in contact with the stress plate 907. When the stress rod 2 905 moves back and forth in the vertical direction, the hydraulic chamber 3 901 slidably connected to the stress rod 2 905 can drive the pressure plate 907 slidably connected to the hydraulic chamber 3 901 to move back and forth in the vertical direction. The pressure plate 907 can intermittently provide an additional force to the cleaning brush 903 through the stress plate 909 and the elastic telescopic member 908, thereby improving the cleaning effect of the cleaning brush 903 on the welding slag on the top of the base 100. The subsequent cleaning operation is reduced, making the device easier to use.

[0031] In use, on the basis of the first and second embodiments, when performing the welding operation, start the electric telescopic rod, drive the moving rod 902 driven by the electric telescopic rod to reciprocate horizontally. The moving rod 902 then drives the cleaning brush 903 assembled at its bottom to reciprocate on the top of the base 100, sweeping the welding slag on the top of the base 100 from the opening on the top of the base 100 into the base 100. At this time, the rapidly rotating gear 702 drives the cam 904 connected to it in transmission to rotate. When the protruding part of the cam 904 rotates to the force receiving rod two 905, it can squeeze the force receiving rod two 905 to compress the spring two 906 and move upward. When the protruding part of the cam 904 continues to rotate and moves away from the force receiving rod two 905, the force receiving rod two 905 can be reset under the action of the spring two 906. In this way, the force receiving rod two 905 can reciprocate vertically. Cooperating with the hydraulic chamber three 901 slidably connected to the force receiving rod two 905, it can drive the pressing plate 907 slidably connected to the hydraulic chamber three 901 to reciprocate vertically. The pressing plate 907 can intermittently provide an additional force to the cleaning brush 903 through the force receiving plate 909 and the elastic telescopic member 908, thereby improving the cleaning effect of the cleaning brush 903 on the welding slag on the top of the base 100.

[0032] As mentioned above, the above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
