Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, and in particular to automobile parts welding equipment. Background Art

[0002] Auto parts refer to the various components and accessories that make up a car, including engines, gearboxes, steering systems, brake systems, chassis systems, body parts, electrical equipment, etc. These parts are assembled and installed to form a complete car. The quality and performance of auto parts are directly related to the safety and reliability of the car. Therefore, they have important research and development value in the automotive industry. In the processing of auto parts, welding is one of the important processing steps. Through welding, parts can be fixed together.

[0003] In the current automobile parts welding process, for most large automobile parts welding, robots or mechanical arms are generally used for automated welding and assembly line production. However, for some small-sized automobile parts, such as seat brackets, cylindrical pins, etc., manual welding with specific fixtures is still required during welding. The welding process is inefficient and the degree of automation is low. Therefore, an automobile parts welding equipment is proposed. Through the designed welding equipment, automatic clamping, docking, rotation and welding of some cylindrical parts on automobiles can be realized, and automated processing of some parts can be realized, thereby improving welding efficiency, reducing manual labor, and ensuring uniformity of welding quality. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides an automobile parts welding equipment. Through the designed welding equipment, it is possible to realize automatic clamping, docking, rotation and welding of some cylindrical parts on automobiles, realize automated processing of some parts, improve welding efficiency, reduce manual labor, and ensure uniformity of welding quality.

[0005] The technical solution adopted by the present invention to solve the technical problem is an automobile parts welding device, comprising a frame, a column is arranged on the top of the frame and a shaft sleeve is installed at the end of the column, an annular clamp seat corresponding to the position is installed at both sides of the shaft sleeve on the top of the frame, a top plate is fixedly connected to the middle position of the top of the frame and a cylinder is arranged on the top plate, and a welding gun located between the bottom of the top plate and the top of the annular clamp seat is installed at the power output end of the cylinder;

[0006] The outer circumference of the annular clamp seat is provided with arc-shaped clamp grooves corresponding to the positions. A fixing frame is fixedly connected to the inside of the annular clamp seat and a screw A is installed inside the fixing frame. A micro servo motor A connected to the power end of the screw A is provided at the end of the fixing frame and a screw sleeve A is connected to the surface of the screw A. A fixed clamp ring extending to the inside of the arc-shaped clamp groove is installed on the top of the screw sleeve A. A rotating shaft A is installed inside the fixed clamp ring and is movably connected to a movable clamp ring through the rotating shaft A.

[0007] By adopting the above technical solution, the fixed clamp ring and the movable clamp ring cooperate to clamp the workpiece and rotate with the annular clamp seat. During the rotation, the workpieces located inside the annular clamp seats on both sides are in a separated state. When it moves close to the bottom of the welding gun, the micro servo motor A runs, and the screw sleeve A drives the fixed clamp ring and the horizontal clamp ring to move through the rotation of the lead screw A. The workpieces inside the annular clamp seats on both sides move synchronously with each other until the welding ends are butted. At this time, the cylinder runs to drive the welding gun to move down to perform welding processing on the welding position.

[0008] Specifically, a cross frame is installed on one side of the bottom of the fixed clamp ring and a lead screw B is built into the cross frame. A micro servo motor B connected to the power end of the lead screw B is installed at the end of the cross frame and a screw sleeve B is connected to the surface of the lead screw B. A connecting rod is installed between the top of the screw sleeve B and the bottom end of the movable clamp ring, and a rotating shaft B is installed at the connection points at both ends of the connecting rod.

[0009] By adopting the above technical solution, the rotation of the screw B is controlled by the micro servo motor B. When the micro servo motor B is running, it controls the rotation of the screw B, and the screw sleeve B moves horizontally along the inside of the cross frame, and then drives the movable clamping ring to deflect around the position of the rotating shaft A through the connecting rod and the rotating shaft B. When the movable clamping ring deflects, the fixed clamping ring does not move. By controlling the deflection of the movable clamping ring, the size of the opening ends of the fixed clamping ring and the movable clamping ring can be opened and closed, which is convenient for clamping and discharging workpieces.

[0010] Specifically, rollers are embedded on opposite sides of the fixed clamp ring and the movable clamp ring, a micro motor is installed on the side of the fixed clamp ring surface close to the roller, and gears are installed on the bottom roller surface inside the fixed clamp ring and the power output end of the micro motor, and the gears are meshed with each other.

[0011] By adopting the above technical solution, after the fixed clamp ring and the movable clamp ring cooperate to clamp the workpiece, the roller on its inner wall contacts the workpiece. When the workpiece is in the welding position for welding, the micro motor will drive the rotation of the gear, and the meshing of the gear will drive the bottom roller to rotate, thereby rotating the workpiece, so that the welding gun can perform complete and comprehensive welding processing on the welding position.

[0012] Specifically, a slide groove is opened horizontally on the top of the frame and a support plate is inserted on the top of the slide groove. A universal bamboo tube is arranged on the top of the support plate and a signal transmitter is installed on the side of the top of the universal bamboo tube facing the annular clamp seat.

[0013] By adopting the above technical solution, the required number of pallets can be inserted into the slide groove position on the top of the frame. A universal bamboo tube is provided on the top of the pallet. The horizontal position of the pallet is adjusted by sliding along the slide groove, and then the universal bamboo tube is bent to adjust the position of the signal transmitter at its end. Different signal transmitters are aligned with the starting positions of different processes on the surface of the annular clamp seat. The control end of the signal transmitter is connected to the main controller, which is pre-set by the main controller so that signal transmitters at different positions transmit different signals.

[0014] Specifically, a main controller is provided on one side of the frame surface, and a microcontroller and a signal receiver are built-in at positions corresponding to the arc-shaped clamp groove inside the annular clamp seat. The surface of the signal receiver extends to the surface of the annular clamp seat, and a communicator corresponding to the position is installed on the opposite side of the inner wall of the annular clamp seat, and the signal transmission end of the communicator is connected to the signal transmission end of the microcontroller.

[0015] By adopting the above technical solution, during the rotation of the annular clamp seat, the signal receivers inside the annular clamp grooves at different positions rotate synchronously. When they rotate to the vicinity of the signal transmitter at the corresponding position, they can receive the corresponding signal, and the microcontroller controls the internal components of the arc-shaped clamp grooves to operate according to the received signals, so that different operations can be performed at different positions. At the same time, after the signal receiver close to one side of the signal transmitter receives the signal, it will transmit the signal to the inside of the annular clamp seat on the other side through the communicator, so that the internal components of the annular clamp seats on both sides can perform operations synchronously.

[0016] Specifically, a gearbox is installed on the side of the frame surface away from the annular clamp seat and a motor is installed at the power output end of the gearbox. A transmission shaft passing through the frame is installed at the power output end of the motor through the gearbox. The transmission shaft passes through the shaft sleeve and the annular clamp seat and the annular clamp seats are connected by the transmission shaft.

[0017] By adopting the above technical solution, the power output end of the motor rotates when it is running. After being decelerated by the gearbox, the annular clamps on both sides of the sleeve can be driven to rotate at a preset speed through the transmission shaft, thereby realizing flow welding operations.

[0018] Specifically, the main controller control end is connected to the motor control end, the main controller signal output end is connected to the signal transmitter communication end, the signal receiver communication end is connected to the microcontroller communication end, and the microcontroller control end is connected to the micro servo motor A, micro servo motor B and micro motor control end.

[0019] By adopting the above technical solution, the main controller regulates the operation of the motor, controls the rotation speed of the equipment body, and sends different signals to the signal transmitters at different positions, so that each component operates according to the preset program. After receiving the signal at the corresponding position, the signal receiver regulates the operation of the micro servo motor A, micro servo motor B and micro motor through the micro controller, so as to realize the orderly progress of the welding process.

[0020] Specifically, the bottom of the support plate is fixedly connected with a sliding block inserted into the inside of the slide groove, and the outer periphery of the sliding block is covered with a rubber sleeve, and the rubber sleeve fits the inner wall of the slide groove.

[0021] By adopting the above technical solution, the pallet is connected to the slide groove through the slider at the bottom, so that the pallet and its top component can slide horizontally along the slide groove to adjust the position. At the same time, the rubber sleeve assembly increases the friction between the slider and the inner wall of the slide groove, so that the position of the pallet, universal bamboo tube and signal transmitter can be kept stable without applying external force.

[0022] Beneficial effects of the present invention:

[0023] (1) The present invention discloses an automobile parts welding device. When the micro servo motor B is running, it controls the lead screw B to rotate, and the screw sleeve B moves horizontally along the inside of the cross frame, and then drives the movable clamp ring to deflect around the position of the rotating shaft A through the connecting rod and the rotating shaft B. When the movable clamp ring deflects, the fixed clamp ring does not move. By controlling the deflection of the movable clamp ring, the size of the opening ends of the fixed clamp ring and the movable clamp ring can be opened and closed, which is convenient for clamping and discharging the workpiece. The fixed clamp ring and the movable clamp ring cooperate to complete the clamping of the workpiece and rotate with the annular clamp seat. During the rotation, the workpieces located inside the annular clamp seats on both sides are in a separated state. When it moves to near the bottom of the welding gun, the micro servo motor A is running. Through the rotation of the lead screw A, the screw sleeve A drives the fixed clamp ring and the horizontal clamp ring to move. The workpieces inside the annular clamp seats on both sides move synchronously relative to each other until the welding ends are butted. At this time, the cylinder drives the welding gun to move downward to perform automated welding processing on the welding position.

[0024] (2) In the automobile parts welding equipment described in the present invention, after the clamping assembly clamps the parts to be welded, the roller on the inner wall contacts the workpiece. When the workpiece is in the welding position for welding, the micro motor will drive the gear to rotate, and the meshing of the gears will drive the bottom roller to rotate, so that the parts can rotate inside the clamping assembly, so that the welding gun can perform a complete and comprehensive welding process on the welding position.

[0025] (3) The automobile parts welding equipment described in the present invention adjusts the slider, the support plate and the universal bamboo tube to align different signal transmitters with the starting positions of different processes on the surface of the annular clamp seat. The main controller performs pre-settings so that signal transmitters at different positions transmit different signals. After the signal receiver runs to different positions and receives the signals at the corresponding positions, the micro-controller controls the operation of the micro-servo motor A, the micro-servo motor B and the micro-motor to achieve orderly progress of the welding process.

When the micro servo motor B409 is running, it controls the rotation of the screw B410, and the screw sleeve B411 moves horizontally along the inside of the cross frame 408, and then drives the movable clamping ring 407 to deflect around the position of the rotating shaft A406 through the connecting rod 412 and the rotating shaft B413. When the movable clamping ring 407 deflects, the fixed clamping ring 405 does not move. By controlling the deflection of the movable clamping ring 407, the opening ends of the fixed clamping ring 405 and the movable clamping ring 407 can be opened and closed, which is convenient for clamping and discharging workpieces.

[0044] When in use, after the fixed clamp ring 405 and the movable clamp ring 407 cooperate to clamp the workpiece, the roller 5 on its inner wall contacts the workpiece. When the workpiece is in the welding position for welding, the micro motor 501 will drive the gear 502 to rotate, and the meshing of the gear 502 will drive the bottom roller 5 to rotate, thereby rotating the workpiece, so that the welding gun 302 can perform a complete and comprehensive welding process on the welding position.

[0045] When in use, the frame 1 is fixed at the welding station, and conveyor lines for loading and unloading can be installed on both sides. The ends of the conveyor lines are located on both sides of the surface of the annular clamp seat 202 and are aligned with the arc clamp groove 4. During operation, the annular clamp seat 202 rotates counterclockwise. The conveyor line on the right side of the front of the frame 1 is the loading conveyor line, and the conveyor line on the left side of the frame 1 is the discharge conveyor line. In the unloaded state, the opening between the fixed clamp ring 405 and the movable clamp ring 407 is larger, which is convenient for the workpiece to enter the arc clamp. Inside the slot 4, the micro servo motor B409 controls the screw B410 to rotate when in operation, and the screw sleeve B411 moves horizontally along the inside of the cross frame 408, and then drives the movable clamp ring 407 to deflect around the position of the rotation axis A406 through the connecting rod 412 and the rotation axis B413. When the movable clamp ring 407 deflects, the fixed clamp ring 405 does not move. By controlling the deflection of the movable clamp ring 407, the size of the opening end of the fixed clamp ring 405 and the movable clamp ring 407 can be opened and closed, which is convenient for clamping and discharging. The fixed clamp ring 405 and the movable clamp ring 407 cooperate to clamp the workpiece and rotate with the annular clamp seat 202. During the rotation, the workpieces located inside the annular clamp seats 202 on both sides are in a separated state. When it moves close to the bottom of the welding gun 302, the micro servo motor A402 runs, and the screw sleeve A404 drives the fixed clamp ring 405 and the horizontal clamp ring to move through the rotation of the lead screw A403. The workpieces inside the annular clamp seats 202 on both sides move synchronously relative to each other until the welding ends are butted. At this time, the cylinder 301 runs to drive the welding gun 302 to move downward to perform automated welding processing on the welding position.

[0046] Embodiment 2:

[0047] The technical solution adopted by the present invention to solve the technical problem is an automobile parts welding device, comprising a frame 1, a column 2 is arranged on the top of the frame 1 and a shaft sleeve 201 is installed at the end of the column 2, an annular clamp seat 202 corresponding to the position is installed at both sides of the shaft sleeve 201 on the top of the frame 1, a top plate 3 is fixedly connected to the middle position of the top of the frame 1 and a cylinder 301 is arranged on the top plate 3, and a welding gun 302 located between the bottom of the top plate 3 and the top of the annular clamp seat 202 is installed at the power output end of the cylinder 301;

[0048] The outer circumference of the annular clamp seat 202 is provided with arc-shaped clamp grooves 4 corresponding to the positions, the annular clamp seat 202 is fixedly connected to a fixing frame 401 inside and a lead screw A403 is installed inside the fixing frame 401, a micro servo motor A402 connected to the power end of the lead screw A403 is provided at the end of the fixing frame 401, and a screw sleeve A404 is connected to the surface of the lead screw A403, a fixed clamp ring 405 extending to the inside of the arc-shaped clamp groove 4 is installed on the top of the screw sleeve A404, a rotating shaft A406 is installed inside the fixed clamp ring 405 and a movable clamp ring 407 is movably connected through the rotating shaft A406.

[0049] When in use, the fixed clamp ring 405 and the movable clamp ring 407 cooperate to clamp the workpiece and rotate with the annular clamp seat 202. During the rotation, the workpieces inside the annular clamp seats 202 on both sides are in a separated state. When it moves close to the bottom of the welding gun 302, the micro servo motor A402 runs, and through the rotation of the lead screw A403, the screw sleeve A404 drives the fixed clamp ring 405 and the horizontal clamp ring to move. The workpieces inside the annular clamp seats 202 on both sides move synchronously with each other until the welding ends are butted. At this time, the cylinder 301 runs to drive the welding gun 302 to move downward to perform welding processing on the welding position.

[0050] Specifically, a slide groove 6 is horizontally opened on the top of the frame 1 and a support plate 601 is inserted on the top of the slide groove 6. A universal bamboo tube 603 is arranged on the top of the support plate 601 and a signal transmitter 604 is installed on the side of the top of the universal bamboo tube 603 facing the annular clamp seat 202.

[0051] When in use, the required number of pallets 601 can be inserted into the slide groove 6 on the top of the frame 1. A universal bamboo tube 603 is provided on the top of the pallet 601. The horizontal position of the pallet 601 is adjusted by sliding along the slide groove 6, and then the universal bamboo tube 603 is bent to adjust the position of the signal transmitter 604 at its end. Different signal transmitters 604 are aligned with the starting positions of different processes on the surface of the annular clamp seat 202. The control end of the signal transmitter 604 is connected to the main controller 7, and the main controller 7 is pre-set so that the signal transmitters 604 at different positions transmit different signals.

[0052] Specifically, a main controller 7 is provided on one side of the surface of the frame 1, and a microcontroller 701 and a signal receiver 702 are built-in at positions corresponding to the arc-shaped clamping groove 4 inside the annular clamp seat 202. The surface of the signal receiver 702 extends to the surface of the annular clamp seat 202, and a communicator 703 corresponding to the position is installed on the opposite side of the inner wall of the annular clamp seat 202, and the signal transmission end of the communicator 703 is connected to the signal transmission end of the microcontroller 701.

[0053] During use, during the rotation of the annular clamp seat 202, the signal receivers 702 inside the annular clamp grooves at different positions rotate synchronously. When they rotate to the vicinity of the signal transmitter 604 at the corresponding position, they can receive the corresponding signal, and the microcontroller 701 controls the internal components of the arc clamp groove 4 to operate according to the received signal, so that different operations can be performed at different positions. At the same time, after the signal receiver 702 on one side close to the signal transmitter 604 receives the signal, it will transmit the signal to the inside of the annular clamp seat 202 on the other side through the communicator 703, so that the internal components of the annular clamp seat 202 on both sides can perform operations synchronously.

[0054] Specifically, a gearbox 203 is installed on the side of the surface of the frame 1 away from the annular clamp seat 202, and a motor 204 is installed at the power output end of the gearbox 203. A transmission shaft 205 that passes through the frame 1 is installed at the power output end of the motor 204 through the gearbox 203. The transmission shaft 205 passes through the shaft sleeve 201 and the annular clamp seat 202, and the annular clamp seats 202 are connected through the transmission shaft 205.

[0055] When in use, the power output end of the motor 204 rotates when it is running, and after being decelerated by the gearbox 203, the annular clamping seats 202 on both sides of the sleeve 201 can be driven to rotate at a preset speed through the transmission shaft 205 to realize flow welding operation.

[0056] Specifically, the control end of the main controller 7 is connected to the control end of the motor 204, the signal output end of the main controller 7 is connected to the communication end of the signal transmitter 604, the communication end of the signal receiver 702 is connected to the communication end of the microcontroller 701, and the control end of the microcontroller 701 is connected to the control ends of the micro servo motor A402, the micro servo motor B409 and the micro motor 501.

[0057] When in use, the main controller 7 regulates the operation of the motor 204, controls the rotation speed of the equipment body, and sends different signals to the signal transmitter 604 at different positions, so that each component operates according to the preset program. After receiving the signal at the corresponding position, the signal receiver 702 regulates the operation of the micro servo motor A402, micro servo motor B409 and micro motor 501 through the micro controller 701, so as to realize the orderly progress of the welding process.

[0058] Specifically, the bottom of the support plate 601 is fixedly connected with a slider 602 inserted into the slide groove 6 , and the outer periphery of the slider 602 is covered with a rubber sleeve 605 , and the rubber sleeve 605 fits the inner wall of the slide groove 6 .

[0059] When in use, the support plate 601 is connected to the slide groove 6 through the slider 602 at the bottom, so that the support plate 601 and its top component can slide horizontally along the slide groove 6 to adjust the position. At the same time, the rubber sleeve 605 component increases the friction between the slider 602 and the inner wall of the slide groove 6, so that without applying external force, the position of the support plate 601, the universal bamboo tube 603 and the signal transmitter 604 can remain stable.

[0060] When in use, by adjusting the slider 602, the support plate 601 and the universal bamboo tube 603, different signal transmitters 604 are aligned with the starting positions of different processes on the surface of the annular clamp seat 202, and the main controller 7 is pre-set so that the signal transmitters 604 at different positions transmit different signals. After the signal receiver 702 runs to different positions and receives the signals at the corresponding positions, the micro-controller 701 is used to regulate the operation of the micro-servo motor A402, the micro-servo motor B409 and the micro-motor 501 to realize the orderly progress of the welding process. For example, in the normal use state, the number of signal transmitters 604 arranged is five. The first group is arranged near the loading end of the parts to transmit the loading preparation signal, the second group is arranged at the top of the loading end to transmit the clamping signal, the third group is arranged near the welding position to transmit the parts docking signal, the fourth group is arranged near the welding position to transmit the rotation signal, the fifth group is arranged near the unloading end to transmit the unloading and reset signal, and the signal transmitter 604 near the loading end of the parts transmits the loading preparation signal. When the arc-shaped clamping groove 4 inside the annular clamp seat 202 runs to this position, the signal receiver 702 receives the signal, and the micro servo motor B40 inside the annular clamp seats 202 on both sides is driven by the linkage. 9 operation, the active clamp ring 407 is driven to deflect by the lead screw assembly, and the distance between it and the fixed clamp ring 405 is increased to facilitate loading. After the parts enter the clamping assembly, they rotate with the annular clamp seat 202. When they run to the second group of signal transmitters 604, the active clamp ring 407 is reversely deflected to cooperate with the fixed clamp ring 405 to complete the clamping and fixing of the parts. When they run to the third group of signal transmitters 604, the micro servo motor A402 located at the corresponding position inside the annular clamp seat 202 on both sides of the shaft sleeve 201 is operated, so that the electric parts of the fixed clamp seat move synchronously relative to each other until the ends are butted. When the signal receiver 702 is connected When the signal from the fourth group of signal transmitters 604 is received, it means that the parts have reached the welding position. At this time, the annular clamp seat 202 stops running, and the micro motor 501 runs to control the rotation of the parts to achieve annular welding processing of the parts welding position. After welding, the annular clamp seat 202 continues to rotate. When the signal emitted by the fifth group of signal transmitters 604 is received, the clamping component opens to discharge the welded parts, and the internal components are reset at the same time to prepare to clamp the next group of parts to be welded. This cycle is repeated to achieve automated welding processing. At the same time, hardware and programming can be added according to different usage requirements so that the internal components can perform other operations.
