[0018] According to an embodiment of this application, a sliding groove is provided on the upper end face of the frame, and a slider is slidably installed in the groove. A support block is installed on the top of the slider, and a connecting rod is provided on the surface of the support block. One end of the connecting rod is fixedly connected to the limiting rod.

[0019] According to an embodiment of this application, a limiting ring is fastened to the surface of the sliding sleeve, and two limiting rings are provided, with the two limiting rings located on both sides of the ring plate respectively.

[0020] According to an embodiment of this application, both the double-ended screw and the prism are offset from the center of the turntable, and the double-ended screw and the prism are parallel to each other.

[0021] According to an embodiment of this application, the cross-section of the slider is convex, and the connection between the support block and the connecting rod is integrally formed.

[0022] According to an embodiment of this application, the two limiting rods are symmetrically arranged, and anti-slip textures are engraved on the opposite sides of the two limiting rods.

[0023] According to an embodiment of this application, the surface of the sliding sleeve is provided with an adjustment mechanism, the adjustment mechanism including a telescopic member and a sliding rod, the telescopic member is installed on the surface of the sliding sleeve, and a support plate is fixed to the movable end of the telescopic member, the sliding rod is rotatably installed on the surface of the support plate, and one end of the sliding rod slides through the sliding sleeve, push blocks are provided at intervals on the surface of the sliding sleeve, and a slot is formed between two adjacent push blocks, a second motor is installed on the surface of the support plate, and the output shaft of the second motor is connected to the sliding rod in a transmission manner.

[0024] According to an embodiment of this application, a friction block is mounted on the surface of the slide rod, and a groove corresponding to the double-ended screw is formed on the surface of the friction block.

[0025] According to an embodiment of this application, the surface of the sliding sleeve is provided with through holes corresponding to the sliding rod and the push block.

[0026] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become obvious from the description below, or will be learned through practice of the present application.

[0027] If the beam vibrates during welding, it may move and shift off the workbench, affecting subsequent processing.

[0028] Once the vehicle beam is inserted into the positioning groove on the surface of the positioning component, the first motor is started, which drives the double-headed screw to rotate. The two sliding sleeves on the surface of the double-headed screw will move relative to each other or in opposite directions. The sliding sleeves will also drive the corresponding ring plate and limit rod to move. After the two limit rods are in contact with the two sides of the vehicle beam on opposite sides, the two limit rods will restrict the movement of the vehicle beam, achieving the effect of positioning the vehicle beam. This makes the vehicle beam more stable and reduces the possibility of the vehicle beam moving.

[0029] Furthermore, when the ring plate moves, it will drive the connecting rod to move, and the connecting rod will pull the support block. After the limit rod moves to the side of the vehicle beam, the support block will move to the bottom of the vehicle beam. The support block will fill the area between the vehicle beam and the frame, so the frame and the support block can support the frame, which can reduce the possibility of the vehicle beam falling and make the vehicle beam more stable. In addition, by supporting the vehicle beam, the pressure of the vehicle beam on the rotating parts can be distributed, thus reducing the pressure on the rotating parts and reducing the possibility of the rotating parts being crushed.

[0030] Furthermore, when the support block moves, it drives the slider to move within the groove. The frame restricts the direction of slider movement, thereby making the movement of the support block more stable. Moreover, by supporting the support block, the frame can also support the connecting rod, ring plate, and sliding sleeve. The sliding sleeve, in turn, supports the double-ended screw and the rib, reducing the possibility of bending deformation of the double-ended screw and the rib under pressure, lowering the possibility of damage to the double-ended screw and the rib, and increasing the service life of the double-ended screw and the rib.

[0031] When a positioning sleeve is fitted onto the surface of a vehicle beam, the positioning sleeve will block part of the vehicle beam, making it impossible to weld parts of the vehicle beam. Furthermore, the positioning sleeve is inconvenient to move, which affects the processing of the beam.

[0032] Before placing the positioning piece on the surface of the vehicle beam, start the second motor to drive the slide bar to rotate. This will cause the push block and friction block on the surface of the slide bar to move until the push block and the positioning piece are misaligned. Then move the positioning piece. This will prevent the push block from obstructing the movement of the positioning piece. In addition, the friction block on the surface of the slide bar will move to the surface of the double-ended screw. When the friction block is in close contact with the double-ended screw, it will increase the resistance encountered by the double-ended screw when it rotates. Therefore, even if the staff accidentally touches the double-ended screw when sliding the positioning piece, it will not easily cause the double-ended screw to rotate.

[0033] When adjusting the position of the positioning component, after the two limiting rods are placed against the opposite sides of the vehicle beam, the two limiting rods will restrict the movement of the vehicle beam. Then, the second motor is restarted and coordinated with the telescopic component. The second motor drives the slide rod to rotate, moving the push block on the surface of the slide rod to the surface of the positioning component. The telescopic component moves through the support plate, which in turn drives the slide rod and the push block on its surface to move. After the positioning component is inserted into the slot formed between the two push blocks, the moving end of the telescopic component continues to support the support plate to move, which allows the slide rod and push block to push the positioning component to move and adjust its position. After the positioning component is moved from its original position, the part of the vehicle beam at the original position of the positioning component can be welded, which can reduce the possibility of welding blind spots and make the processing of the vehicle beam more convenient.

Detailed Implementation

[0044] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] The following description, with reference to the accompanying drawings, describes a beam flipping and positioning device for welding and processing vehicle parts according to an embodiment of this application.

[0047] like Figures 1-8 As shown, the vehicle component welding processing beam flipping and positioning device according to an embodiment of this application includes: a frame mechanism 100, a flipping mechanism 200, and a drive motor 300.

[0048] The tilting mechanism 200 is disposed on the surface of the frame mechanism 100, and the drive motor 300 is used to drive the tilting mechanism 200 so that the tilting mechanism 200 can tilt the vehicle beam.

[0049] The frame structure 100 includes a frame 110 and a frame rod 120. The frame rod 120 is fixed inside the frame 110, and a frame plate 130 is installed on the upper end face of the frame 110. In specific implementation, the frame rod 120 can be fixed inside the frame 110 by welding. The setting of the frame rod 120 can improve the strength of the frame 110.

[0050] The flipping mechanism 200 includes a rotating component 210 and a positioning component 220. The rotating component 210 is rotatably mounted on the surface of the frame plate 130, and the positioning component 220 is disposed on the surface of the rotating component 210. The surface of the positioning component 220 is provided with a contour groove 230. In specific implementation, the vehicle beam is inserted into the contour groove 230, and the rotating component 210 rotates, which drives the positioning component 220 and the vehicle beam inside it to rotate, thereby achieving the purpose of flipping the vehicle beam.

[0051] The drive motor 300 is mounted on the surface of the frame 110, and the drive end of the drive motor 300 is connected to the rotating component 210 in a transmission manner. In a specific implementation, the drive motor 300 is used to drive the rotating component 210 to rotate.

[0052] The working process of a beam flipping and positioning device for welding and processing vehicle parts according to a specific embodiment of this application is described below with reference to the accompanying drawings.

[0053] First, use hoisting equipment such as gantry cranes to hoist the vehicle beams to be welded onto the surface of the frame 110;

[0054] Then slide the positioning piece 220 and place it on the surface of the vehicle beam. The vehicle beam will then be inserted into the contour groove 230 on the surface of the positioning piece 220.

[0055] When the drive motor 300 is started, the rotating component 210 is driven to rotate, which in turn causes the positioning component 220 and the vehicle beam to rotate, thus causing the vehicle beam to flip.

[0056] Therefore, the vehicle component welding processing beam flipping and positioning device according to the embodiment of this application uses a plug-in method to insert the vehicle beam into the contour groove 230 on the surface of the positioning member 220, so that the positioning member 220 can position the vehicle beam. By cooperating with the drive motor 300 and the rotating member 210, the positioning member 220 and the vehicle beam are driven to rotate, so that the vehicle beam can be flipped. The degree of automation is high and the workload of the workers is reduced.

[0057] In addition, the beam flipping and positioning device for welding and processing vehicle parts according to the embodiments of this application also has the following additional technical features:

[0058] According to embodiments of this application, such as Figure 1 and Figure 2 As shown, the bottom of the frame 110 is provided with support legs 111, and the support legs 111 are arranged in pairs opposite each other. In specific implementation, the support legs 111 are provided to support the frame 110 and increase the distance between the frame 110 and the ground.

[0059] According to embodiments of this application, such as Figure 1 and Figure 2 As shown, at least two support rods 120 are spaced apart along the length of the frame 110, and a cavity is formed between two adjacent support rods 120. In specific implementation, when the vehicle beam is placed above the frame 110, the multiple support rods 120 can support the vehicle beam.

[0060] According to embodiments of this application, such as Figure 1 , Figure 3 and Figure 4As shown, the rotating component 210 includes a turntable 211 and a prism rod 212. The turntable 211 is rotatably mounted on the surface of the frame plate 130, and the prism rod 212 is fixed to the surface of the turntable 211. In a specific implementation, a bearing is provided at the connection between the turntable 211 and the frame plate 130. When the turntable 211 rotates, the prism rod 212 can move. It can be understood that there are two frames 130 and two turntables 211, and the two turntables 211 are located on both sides of the prism rod 212. The two frames 130 and two turntables 211 can better support the prism rod 212. It should be noted that the drive motor 300 is a servo motor, and the output shaft of the drive motor 300 is connected to the turntable 211 for transmission. The drive motor 300 is used to drive the turntable 211 to rotate. Furthermore, the drive motor 300 has a servo system, which can control the speed and has very accurate position. It can convert voltage signals into torque and speed to drive the controlled object. Servo motor rotor speed is controlled by input signal and can respond quickly. In automatic control systems, it is used as an actuator and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft.

[0061] According to embodiments of this application, such as Figure 1 , Figure 3 and Figure 4 As shown, at least two positioning elements 220 are spaced apart along the length of the rib 212. The presence of multiple positioning elements 220 facilitates the positioning of the vehicle beam.

[0062] According to embodiments of this application, such as Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the positioning component 220 includes a prism sleeve 221 and a positioning sleeve 222. The prism sleeve 221 is slidably fitted onto the surface of the prism rod 212, and the positioning sleeve 222 is fixed to the surface of the prism sleeve 221. A contour groove 230 is formed on the surface of the positioning sleeve 222. It can be understood that the specifications of the contour groove 230 can be determined according to the specifications of the vehicle beam to be welded in the actual situation. When the prism sleeve 221 moves on the surface of the prism rod 212, it can drive the positioning sleeve 222 to move, thereby adjusting the position of the positioning component 220 on the surface of the prism rod 212. It should be noted that a fastening bolt 223 is screwed onto the surface of the positioning sleeve 222. One end of the fastening bolt 223 is slidably inserted into the contour groove 230. After the vehicle beam is inserted into the contour groove 230, the fastening bolt 223 is rotated to move the fastening bolt 223 toward the vehicle beam until one end of the fastening bolt 223 contacts the vehicle beam, thus fixing the vehicle beam and making the connection between the vehicle beam and the fastening bolt 223 more stable. Preferably, the connection between the prism sleeve 221 and the positioning sleeve 222 is integrally formed, and both the surface of the prism sleeve 221 and the surface of the positioning sleeve 222 are provided with rounded corners. The integral forming design can make the connection between the prism sleeve 221 and the positioning sleeve 222 more stable.

[0063] If the beam vibrates during welding, it may move and shift off the workbench, affecting subsequent processing.

[0064] According to embodiments of this application, such as Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, a limiting mechanism 400 is provided on the surface of the rotating component 210. The limiting mechanism 400 includes a double-ended screw 410 and a first motor 420. The double-ended screw 410 is rotatably mounted on the surface of the turntable 211. The first motor 420 is connected to the turntable 211, and the output shaft of the first motor 420 is drively connected to the double-ended screw 410. Both threaded sections of the double-ended screw 410 are threadedly fitted with sliding sleeves 430. The end of the rib 212 slides through the sliding sleeves 430, and the surfaces of the two sliding sleeves 430 are rotatably fitted with... There is a ring plate 440, and a limit rod 450 is fixed on the surface of the ring plate 440. The double-headed screw 410 is composed of two screws of the same specification welded symmetrically. The first motor 420 is used to drive the double-headed screw 410 to rotate. The upper end face of the frame 110 is provided with a sliding groove 112, and a slider 460 is slidably installed in the groove of the sliding groove 112. A support block 470 is installed at the top of the slider 460, and a connecting rod 480 is provided on the surface of the support block 470. One end of the connecting rod 480 is fixedly connected to the limit rod 450.

[0065] In practical implementation, after the vehicle beam is inserted into the positioning groove on the surface of the positioning component 220, the first motor 420 is started, and the first motor 420 drives the double-headed screw 410 to rotate. Then, the two sliding sleeves 430 on the surface of the double-headed screw 410 will move relative to each other or in opposite directions. Moreover, the sliding sleeves 430 will drive the corresponding ring plate 440 and the limiting rod 450 to move. After the two limiting rods 450 are attached to the two sides of the vehicle beam on opposite sides, the two limiting rods 450 will restrict the movement of the vehicle beam, achieve the effect of positioning the vehicle beam, make the vehicle beam more stable, and reduce the possibility of the vehicle beam moving.

[0066] Furthermore, when the ring plate 440 moves, it will drive the connecting rod 480 to move, and the connecting rod 480 will pull the support block 470. After the limit rod 450 moves to the side of the vehicle beam, the support block 470 will move to the bottom of the vehicle beam. The support block 470 will fill the area between the vehicle beam and the frame 110, so the frame 110 and the support block 470 can support the frame 110, which can reduce the possibility of the vehicle beam falling and make the vehicle beam more stable. In addition, by supporting the vehicle beam, the pressure of the vehicle beam on the rotating part 210 can be distributed. By reducing the pressure on the rotating part 210, the possibility of the rotating part 210 being crushed is reduced.

[0067] Furthermore, when the support block 470 moves, it drives the slider 460 to move within the slide groove 112. The frame 110 restricts the movement direction of the slider 460, thereby making the movement of the support block 470 more stable. Moreover, by supporting the support block 470, the frame 110 can also support the connecting rod 480, the ring plate 440, and the sliding sleeve 430. The sliding sleeve 430 supports the double-ended screw 410 and the rib 212, reducing the possibility of bending deformation of the double-ended screw 410 and the rib 212 under pressure, reducing the possibility of damage to the double-ended screw 410 and the rib 212, and improving the service life of the double-ended screw 410 and the rib 212.

[0068] According to an embodiment of this application, a limiting ring 431 is fastened to the surface of the sliding sleeve 430, and two limiting rings 431 are provided. The two limiting rings 431 are respectively located on both sides of the ring plate 440. In a specific implementation, a bearing is provided at the connection between the sliding sleeve 430 and the ring plate 440, and the limiting ring 431 can be fixed to the sliding sleeve 430 by welding. By providing two limiting rings 431, the movement of the ring plate 440 can be restricted, and the ring plate 440 can be more stably installed on the surface of the sliding sleeve 430.

[0069] According to the embodiments of this application, both the double-ended screw 410 and the prism 212 are offset from the center of the turntable 211, and the double-ended screw 410 and the prism 212 are parallel to each other. Since the double-ended screw 410 and the prism 212 are parallel, their length directions are the same. When the sliding sleeve 430 moves along the length direction of the double-ended screw 410, the prism 212 can restrict the movement direction of the sliding sleeve 430, making the movement of the sliding sleeve 430 more stable.

[0070] According to an embodiment of this application, the cross-section of the slider 460 is convex, and the connection between the support block 470 and the connecting rod 480 is integrally formed. The integrally formed design makes the connection between the support block 470 and the connecting rod 480 more secure.

[0071] According to an embodiment of this application, two limiting rods 450 are symmetrically arranged, and anti-slip textures are engraved on the opposite sides of the two limiting rods 450. The anti-slip texture design can increase the friction between the limiting rods 450 and the vehicle beam, which is more conducive to the positioning of the vehicle beam.

[0072] When a positioning sleeve is fitted onto the surface of a vehicle beam, the positioning sleeve will block part of the vehicle beam, making it impossible to weld parts of the vehicle beam. Furthermore, the positioning sleeve is inconvenient to move, which affects the processing of the beam.

[0073] According to embodiments of this application, such as Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the surface of the sliding sleeve 430 is provided with an adjustment mechanism 500, which includes a telescopic member 510 and a sliding rod 520. The telescopic member 510 is installed on the surface of the sliding sleeve 430, and a support plate 530 is fixed to the movable end of the telescopic member 510. The sliding rod 520 is rotatably installed on the surface of the support plate 530, and one end of the sliding rod 520 slides through the sliding sleeve 430. Push blocks 540 are spaced apart on the surface of the sliding sleeve 430, and a slot is formed between two adjacent push blocks 540. A second motor 550 is installed on the surface of the support plate 530, and the output shaft of the second motor 550 is connected to the sliding rod 520 for transmission. A friction block 560 is installed on the surface of the sliding rod 520, and a groove corresponding to the double-ended screw 410 is opened on the surface of the friction block 560. In specific implementation, the telescopic member 510 can be any one of a cylinder, an electric cylinder, an electric push rod, and a hydraulic cylinder.

[0074] In practical implementation, before placing the positioning component 220 on the surface of the vehicle beam, the second motor 550 is started first, causing the second motor 550 to drive the slide rod 520 to rotate. This will cause the push block 540 and friction block 560 on the surface of the slide rod 520 to move until the push block 540 and the positioning component 220 are misaligned. Then the positioning component 220 is moved. This avoids the push block 540 from obstructing the movement of the positioning component 220. Moreover, the friction block 560 on the surface of the slide rod 520 will move to the surface of the double-ended screw 410. When the friction block 560 is in close contact with the double-ended screw 410, it will increase the resistance encountered by the double-ended screw 410 when it rotates. Therefore, when sliding the positioning component 220, even if the staff accidentally touches the double-ended screw 410, it will not easily cause the double-ended screw 410 to rotate.

[0075] When adjusting the position of the positioning component 220, after the two limiting rods 450 are respectively attached to the two sides of the vehicle beam, the two limiting rods 450 will restrict the movement of the vehicle beam. When the second motor 550 is restarted and coordinated with the telescopic component 510, the second motor 550 will drive the slide rod 520 to rotate, moving the push block 540 on the surface of the slide rod 520 to the surface of the positioning component 220. The telescopic component 510 moves through the support plate 530, thereby driving the slide rod 520 and its surface. As the push block 540 moves, after the positioning member 220 is inserted into the slot formed between the two push blocks 540, the movable end of the telescopic member 510 continues to support the support plate 530, which can cause the slide rod 520 and the push block 540 to push the positioning member 220 to move and adjust the position of the positioning member 220. After the positioning member 220 is moved away from its original position, the part of the vehicle beam at the original position of the positioning member 220 can be welded, which can reduce the possibility of welding blind spots and make the processing of the vehicle beam more convenient.

[0076] According to an embodiment of this application, the surface of the sliding sleeve 430 is provided with through holes corresponding to the sliding rod 520 and the push block 540. The through holes reduce the obstruction caused by the sliding sleeve 430 to the movement of the sliding rod 520 and the push block 540.

[0077] Other components and operations of the beam flipping and positioning device for welding and processing vehicle parts according to the embodiments of this application are known to those skilled in the art and will not be described in detail here.
