Description

Technical Field

[0001] The invention relates to welding equipment technology, in particular to a high-efficiency assembly welding equipment for automobile beam frames. Background Art

[0002] As is known, the automobile beam frame is an important component of the automobile. Depending on the type of automobile, the beam frame structure is different. Some beam frames are composed of rods and sheet metals, and some beam frames are composed of rods connected to each other. In order to ensure the connection strength, the rods are connected by welding. At present, when assembling automobile beam frames on the market, automatic welding is generally performed using automatic semi-automatic arc, plasma arc welding machines and other equipment. During the welding process, the automobile beam frame is generally placed on a welding base, and multiple groups of beam frames are aligned before welding.

[0003] The disadvantage of the prior art is that, in the process of welding automobile beam frames, generally after the automobile beam frame is placed on the welding table, a welding frame with a welding machine installed inside is used to perform mobile welding on the welding table, and manual work is required to follow the welding position to knock on the position after welding, so as to knock off the welding slag at the welding position, and use a cleaning tool to clean the knocked-off welding slag after welding. This welding and cleaning method is inefficient. If the welding slag is not knocked off in time, it will affect the welding position, and it is also impossible for the staff to directly check whether there are welding cracks at the welding position. If the knocked-off welding slag is not cleaned up in time, the splashed welding slag will fall to the subsequent welding point position, which will affect the welding effect of the automobile beam frame. The existing method generally cannot realize the combination of the welding machine and the cleaning structure, and the welding position is knocked and the welding slag is removed synchronously after welding, which not only affects the welding effect, but also affects the welding efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide an efficient automobile beam frame assembly and welding device to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above-mentioned object, the present invention provides the following technical solution: comprising a welding table for welding automobile beam frames, the automobile beam frames waiting for welding after adding flux are placed on the surface of the welding table, a welding frame is movably installed above the welding table, and a welding machine for movably welding the automobile beam frames is installed inside the welding frame;

[0006] It also includes a striking piece for striking the position of the automobile beam frame after welding, and the striking piece transmits the power of the moving welding machine on the automobile beam frame to the striking piece and the adsorption piece through the resistance piece, so that the welding point is struck intermittently while the welding machine moves and welds, and the welding slag is cleaned in cooperation with the adsorption piece and the cleaning piece;

[0007] The striking piece includes a hammer for striking the welding point, the hammer is fixedly mounted on the top of the rotating plate, the inner side of the bottom end of the rotating plate is fixedly connected to the surface of the transmission gear through a rotating rod, the bottom of the front end of the rotating plate is fixedly connected to a gasket, the bottom of the gasket is elastically connected to the fixed plate through a buffer spring, the fixed plate is fixedly mounted on the bottom of the outer side of the welding machine, a sliding rod is fixedly mounted on the middle part of the rotating plate on the side that fits the surface of the welding machine, the sliding rod is slidably connected in the sliding groove through an extrusion spring, the sliding groove is arc-shaped and opened on the surface of the welding machine to adapt to the movement trajectory of the sliding rod when the rotating plate rotates, the striking end of the hammer is lifted by the intermittent clockwise rotation of the transmission gear, and the transmission gear and the striking end of the hammer are lifted. After the resistance rods are separated, the diagonal gear cooperates with the reset rotation of the torsion spring shaft and the buffer spring rebounds due to the tensile force it is subjected to when the hammer is lifted. Combined with the extrusion spring, the slide rod is reset in the slide groove, and the hammer is pulled downward to knock on the welded position and knock off the welding slag for cleaning. The setting of the buffer spring can keep the bottom of the hammer at a small distance from the welding position without contacting the welding point when knocking is not needed. At the same time, when knocking, the hammer can also knock on the welding position with a certain force under the force of the triple positioning.

[0008] As a further description of the above technical solution: the resistance member realizes the division of power into three parts through the intermittent transmission between the transmission gear arranged inside and the power member and the transmission member:

[0009] The first part drives the lifting and hammering of the hammer when the transmission gear is driven to rotate intermittently through the transmission member and the power member;

[0010] The second part is to drive the adsorption part to scrape against the surface of the welded automobile beam frame through the diagonal gears arranged in the abutment part;

[0011] The third part drives the cleaning part to clean the surface of the automobile beam frame through the rotation of the transmission gear, and sweeps the welding slag into the adsorption part for cleaning;

One end of the rod is inserted in the rotating sleeve and is intermittently inserted in the tooth groove on the surface of the transmission gear. The transmission gear is rotatably installed in the rotating sleeve, and the transmission gear has a certain thickness, and half of the thickness of the transmission gear is rotatably installed in the rotating sleeve, and the other half of the thickness of the transmission gear is exposed on the outside of the rotating sleeve and is meshed and connected to the diagonal gear on one side. The diagonal gear is arranged on the side of the transmission gear away from the transmission wheel, and one side of the diagonal gear is installed in the welding machine through a bearing, and the other side of the diagonal gear is installed on the inner wall of the other side of the welding machine through a torsion spring shaft that can rotate by itself. One side of the diagonal gear is meshed and connected to the rack on the other side of the transmission gear, and the rack is slidably installed on the end of the welding machine opposite to the transmission wheel through a limit piece.

[0013] As a further description of the above technical solution: a hammer for striking the welding position is arranged in the striking piece, and the hammer is lifted by the intermittent power generated by the resistance piece and quickly resets the hammer in cooperation with the torsion spring shaft and the extrusion spring to strike the welding position.

[0014] As a further description of the above technical solution: the resistance member is connected to the moving member through the power member and the transmission member to achieve power input to the resistance member;

[0015] The resistance member is provided with a diagonal gear with gears symmetrically arranged on the surface, which is meshed and connected with a transmission gear that is intermittently connected to the rotation of the power member. The meshing between the diagonal gear and the transmission gear, coordinated with the intermittent rotation of the transmission gear, realizes the lifting and striking of the hammer and the adhesion of the adsorption member to the surface of the automobile beam frame, and at the same time drives the cleaning member to clean the surface of the automobile beam frame.

[0016] As a further description of the above technical solution: the moving part is arranged at the bottom of the welding machine away from one end, the moving part is attached to the surface of the automobile beam frame and rotates with the movement of the welding frame, and cooperates with the transmission part to provide a power source for the resistance part and the striking part;

[0017] The moving part is a transmission wheel rotatably installed at one end of the bottom of the welding machine. When the welding frame is moved above the welding table, the welding machine moves the transmission wheel on the surface of the automobile beam frame placed on the surface of the welding table. The transmission wheel is installed through a bearing and connected to the transmission part. The clockwise rotation power generated by the transmission wheel when it moves from left to right is transmitted to the power part through the transmission part.

[0018] As a further description of the above technical solution: the transmission member is arranged between the moving member and the power member, and is used to transmit the power generated by the moving member into the power member, and keep the power member rotating with the rotation of the moving member;

[0019] The transmission member includes a transmission shaft installed on one side of the transmission wheel, and the other side of the transmission wheel is installed through a bearing. The transmission shaft is connected to the power member through a transmission belt, so that the transmission belt drives the power member to rotate clockwise during the clockwise rotation of the transmission wheel.

[0020] As a further description of the above technical solution: the power member is arranged between the transmission member and the resistance member, and transmits the power generated by the transmission member to the resistance member, so as to realize intermittent transmission of the resistance member to the striking member;

[0021] The power part includes a rotating column connected to the transmission shaft through a transmission belt. The rotating column is fixedly installed at the end of the rotating sleeve. The rotating column and the rotating sleeve are convexly formed as an integral unit, and the rotating sleeve is hollow. A cavity channel is also arranged in the rotating column. The cavity opened in the rotating sleeve realizes the rotational installation of the transmission gear arranged in the conflicting member. At the same time, the channel opened in the rotating column and connected to the cavity in the rotating sleeve facilitates the rotation of the rotating rod between the connecting transmission gear and the cleaning roller arranged in the cleaning member. The rotating sleeve is rotatably installed in a fixed sleeve arranged in the conflicting member, and the fixed sleeve is also arranged in a cavity shape and a through hole is opened at the center of the bottom to facilitate the rotation and insertion of the rotating column, and the rotating sleeve is fixedly installed in the welding machine.

[0022] As a further description of the above technical solution: the adsorption member is arranged at one end of the welding machine away from the moving member through a limiting member, so as to knock the position after welding by the welding machine, and adsorb and clean the knocked welding slag to maintain the cleanliness of the surface of the automobile beam frame;

[0023] The adsorption member cooperates with the intermittent transmission of the abutment member to realize that the vacuum cleaner arranged in the adsorption member moves up and down on the surface of the automobile beam frame, and performs intermittent bonding cleaning on the surface of the automobile beam frame;

[0024] The adsorption part includes a vacuum cleaner installed at the bottom end of the rack. The dust suction port opened at the top of the vacuum cleaner is rotatably installed with a scraper for scraping against the surface of the automobile beam frame. At the same time, the scraper can cooperate with the cleaning part to provide guidance for the welding slag cleaned by the cleaning part, and the welding slag is guided into the vacuum cleaner through the scraper for adsorption and cleaning.

[0025] As a further description of the above technical solution: the cleaning member cooperates with the intermittent transmission of the abutment member to drive the cleaning roller in the cleaning member to intermittently rotate on the surface of the automobile beam frame, and cooperates with the adsorption member to automatically clean the welding slag on the surface of the automobile beam frame;

[0026] The cleaning member includes a cleaning roller fixedly connected to the transmission gear through a rotating rod. When the cleaning roller rotates clockwise on the moving wheel, when there is no interference between the interference member and the transmission gear, the transmission gear is fixed and does not rotate, and the cleaning roller does not rotate either. When there is interference between the interference member and the transmission gear, the transmission gear rotates clockwise, and the transmission gear drives the cleaning roller to rotate clockwise through the rotating rod. When the adsorption member is lowered to adsorb the welding slag in cooperation with the limiting member, the cleaning roller rotates clockwise, thereby sweeping the welding slag away from the position of the adsorption member into the adsorption member, thereby improving the cleaning efficiency of the welding slag on the surface of the automobile beam frame.

[0027] In the above technical solution, the present invention provides an efficient automobile beam frame assembly welding device, wherein the intermittent meshing connection between the rack provided in the limiter and the diagonal gear provided in the abutment member realizes the intermittent deployment of the adsorption member at the bottom of the welding machine and the automatic cleaning of the automobile beam frame surface by the cleaning member;

[0028] The limiting member includes an upper sliding block connected to the rack away from the top of one side of the diagonal gear by a hinge, and the middle section of the rack is connected to the lower sliding block by a limiting spring, and the upper sliding block and the lower sliding block are both slidably connected in the sliding rail, and the sliding rail is for an inner wall of the top end of the welding machine, and a cross bar is fixedly installed at the bottom of the sliding rail for limiting the sliding trajectory of the rack, and the cross bar is slidably inserted in the limiting groove opened at the bottom end of the rack, and the cross bar slides in the limiting groove, and the angle opened by the limiting groove is matched with the movement trajectory of the rack when the diagonal gear rotates. The circular arc movement of the surface teeth of the surface is better, and the meshing movement between the rack and the diagonal gear is better. An adsorption member is installed at the bottom end of the rack, and the rack drives the adsorption member to move downward when the diagonal gear rotates counterclockwise, and the adsorption member is attached to the surface of the automobile beam frame, and the welding slag knocked off the surface of the automobile beam frame by the knocking member is adsorbed and cleaned, and when the diagonal gear rotates clockwise to reset, the adsorption member is pulled upward and reset by the rack.

When the cleaning roller 1201 rotates clockwise on the moving wheel, when there is no conflict between the abutment 8 and the transmission gear 807, the transmission gear 807 is fixed and does not rotate, and the cleaning roller 1201 does not rotate either. When there is conflict between the abutment 8 and the transmission gear 807 and the transmission gear 807 rotates clockwise, the transmission gear 807 drives the cleaning roller 1201 to rotate clockwise through the rotating rod 1202. When the adsorption member 11 is lowered to adsorb the welding slag in cooperation with the limiting member 10, the cleaning roller 1201 rotates clockwise, thereby sweeping the welding slag away from the position of the adsorption member 11 into the adsorption member 11, thereby improving the cleaning efficiency of the welding slag on the surface of the automobile beam frame 4.

[0083] In another embodiment provided by the present invention, preferably, the intermittent meshing connection between the rack 804 provided in the limiting member 10 and the diagonal gear 803 provided in the abutting member 8 is realized to realize the intermittent deployment of the adsorption member 11 at the bottom of the welding machine 3 and the automatic cleaning of the surface of the automobile beam frame 4 by the cleaning member 12;

[0084] The limiting member 10 includes an upper slider 1005 connected to the top of the side of the rack 804 away from the diagonal gear 803 through a hinge 1006, and the middle section of the rack 804 is connected to the lower slider 1001 through a limiting spring 1007. The upper slider 1005 and the lower slider 1001 are both slidably connected in the slide rail 1002. The slide rail 1002 is provided on the inner wall of the top end of the welding machine 3, and a cross bar 1004 for limiting the sliding trajectory of the rack 804 is fixedly installed at the bottom of the slide rail 1002. The cross bar 1004 is slidably inserted in the limiting groove 1003 provided at the bottom end of the rack 804. The movement of the rack 804 is coordinated with the angle of the limit groove 1003, and the movement trajectory of the rack 804 is adapted to the circular arc movement of the surface teeth of the diagonal gear 803 when it rotates, so as to better achieve the meshing movement between the rack 804 and the diagonal gear 803. An adsorption member 11 is installed at the bottom end of the rack 804, and the rack 804 drives the adsorption member 11 to move downward while the diagonal gear 803 rotates counterclockwise, and the adsorption member 11 is attached to the surface of the automobile beam 4, and the welding slag knocked off the surface of the automobile beam 4 by the knocking member 9 is adsorbed and cleaned, and when the diagonal gear 803 rotates clockwise to reset, the adsorption member 11 is pulled upward to reset through the rack 804.

[0085] During use, the automobile beam frame 4 to be welded is fixed on the surface of the welding table 1 using a crane or other equipment, and after the welding is done, and the required flux is added, the welding frame 2 moves from left to right above the welding table 1 under the limitation of its own power and the track on the welding table 1, and the welding machines 3 arranged at both ends of the bottom of the welding frame 2 are used to synchronously weld the butt joints on both sides of the automobile beam frame 4, and the driving wheel 501 at one end of the bottom of the welding machine 3 is attached to the surface of the automobile beam frame 4, and rotates in contact with the surface of the automobile beam frame 4 as the welding frame 2 moves from left to right, and the welding machine 3 welds while moving;

[0086] When the welding machine 3 moves from left to right for welding, the transmission wheel 501 installed at the bottom of the welding machine 3 rotates clockwise, and the rotating sleeve 701 and the rotating column 702 rotate clockwise through the transmission belt 602 and the transmission shaft 601. When the rotating sleeve 701 rotates clockwise, when the inner wall of the fixed sleeve 801 contacts and slides with the top of the interference rod 805, the interference rod 805 is not subjected to the extrusion force and therefore is not inserted into the rotating sleeve 701. At this time, the transmission gear 807 is in a stationary state. When the rotating sleeve 701 rotates to make the top of the interference rod 805 contact and slide with the surface of the protrusion 809 set on the inner wall of the fixed sleeve 801, the interference rod 805 is self-extruded by the protrusion 809. Due to the limitation of the body size, the bottom end of the resistance rod 805 is inserted into the rotating sleeve 701, so that the bottom end of the resistance rod 805 is inserted into the tooth groove of the transmission gear 807 provided in the rotating sleeve 701, so that under the limiting effect of the resistance rod 805, a power connection is formed between the transmission gear 807 and the rotating sleeve 701, so that the rotational force of the rotating sleeve 701 drives the transmission gear 807 to rotate clockwise through the resistance rod 805, and the fixed sleeve 801 is fixed. The rotating sleeve 701 rotates clockwise in the fixed sleeve 801, thereby cooperating with the resistance rod 805 to drive the transmission gear 807 to rotate. When the transmission gear 807 rotates, the power is divided into three parts for transmission:

[0087] In the first part, the transmission member 6 and the power member 7 drive the intermittent rotation of the transmission gear 807, thereby driving the hammer 901 to be lifted and hammered;

[0088] The transmission gear 807 rotates through the rotating rod 1202 connected to the surface to drive the rotating plate 905 and the hammer 901 to rotate clockwise, thereby lifting the striking end of the hammer 901;

[0089] In the second part, the diagonal gear 803 provided in the abutment member 8 drives the adsorption member 11 to scrape against the surface of the welded automobile beam frame 4;

[0090] The transmission gear 807 rotates clockwise to drive the diagonal gear 803 meshing on one side to rotate counterclockwise, and the gear on the other side of the diagonal gear 803 meshes with the rack 804, so that the rack 804 slides downward. The rack 804 is restricted by the sliding track of the upper slider 1005 and the lower slider 1001 in the slide rail 1002 and the sliding track of the cross bar 1004 in the limit groove 1003, so that the vacuum cleaner 1101 slides downward, and the scraper 1102 set on the top of the vacuum cleaner 1101 is attached to the surface of the automobile beam frame 4, so as to absorb and clean the welding slag knocked off the surface of the automobile beam frame 4;

[0091] The third part, through the rotation of the transmission gear 807, drives the cleaning member 12 to clean the surface of the automobile beam frame 4, and sweeps the welding slag into the adsorption member 11 for cleaning;

[0092] The transmission gear 807 rotates clockwise along with the rotating sleeve 701 under the resistance of the resistance rod 805, and drives the cleaning roller 1201 to rotate clockwise through the rotating rod 1202. Therefore, when the cleaning roller 1201 rotates clockwise, the welding slag that is far away from the vacuum cleaner 1101 and is knocked on the surface of the automobile beam frame 4 is swept to the vacuum cleaner 1101 attached to the surface of the automobile beam frame 4, and the scraper 1102 is cooperated to adsorb the welding slag in the vacuum cleaner 1101, so as to realize the adsorption and cleaning of the knocked welding slag during the welding process.

[0093] The rotating sleeve 701 continues to rotate clockwise. After the top end of the resistance rod 805 slides to separate from the protrusion 809, the top end of the resistance rod 805 contacts the inner wall of the fixed sleeve 801. The resistance rod 805 pops out from the rotating sleeve 701 under the rebound action of the return spring 810, thereby separating the bottom end of the resistance rod 805 from the transmission gear 807. After the resistance rod 805 and the transmission gear 807 are separated, the transmission gear 807 stops rotating. At this time, the rotating sleeve 701 continues to rotate clockwise. When the transmission gear 807 stops rotating clockwise, it is subjected to three counterclockwise forces:

[0094] Part 1: When the diagonal gear 803 rotates counterclockwise, it drives the torsion spring shaft 802 connected between the diagonal gear 803 and the inner wall of the welding machine 3 to tighten and rotate. After the diagonal gear 803 loses the rotation force of the transmission gear 807, the torsion spring shaft 802 in the diagonal gear 803 will automatically rotate clockwise, thereby driving the transmission gear 807 to rotate counterclockwise;

[0095] Part 2: When the transmission gear 807 drives the rotating plate 905 and the hammer 901 to rotate and lift clockwise through the rotating rod 1202, the rotating plate 905 will pull the buffer spring 903 connected to the fixed plate 902 through the gasket 904. When the transmission gear 807 cannot rotate clockwise with the rotating sleeve 701, the buffer spring 903 will be stretched and reset to pull the rotating plate 905 to rotate downward, thereby pulling the transmission gear 807 to rotate counterclockwise through the rotating rod 1202;

[0096] Part 3: When the transmission gear 807 drives the rotating plate 905 and the hammer 901 to rotate and lift clockwise through the rotating rod 1202, the sliding rod 906 provided in the middle section of the inner side of the rotating plate 905 slides in the sliding groove 908 and compresses the squeezing spring 907. After the transmission gear 807 loses the power to rotate, the squeezing spring 907 is squeezed and reset, thereby squeezing the sliding rod 906 downward in the sliding groove 908, thereby driving the transmission gear 807 to rotate counterclockwise through the rotating plate 905;

[0097] Under the action of these three parts, the following three effects are achieved:

[0098] The first effect: the counterclockwise rotation of the transmission gear 807 drives the cleaning roller 1201 to rotate counterclockwise, so as to clean the welding slag on the surface of the automobile beam frame 4 away from the vacuum cleaner 1101 to the side away from the vacuum cleaner 1101, so as to prevent the welding slag that has not been cleaned from being missed by the vacuum cleaner 1101 as the welding machine 3 moves from left to right when the welding machine 3 continues to move forward, resulting in a part of the welding slag on the surface of the automobile beam frame 4 being lost and not cleaned, and manual cleaning is required;

[0099] The second effect: the clockwise rotation of the diagonal gear 803 drives the meshing rack 804 to lift up, thereby lifting the vacuum cleaner 1101 upward, and at this time, the deformation ability and rotation of the scraper 1102 itself continue to fit the surface of the automobile beam frame 4, scraping and cleaning the surface of the automobile beam frame 4, and cooperating with the first effect to better clean the surface of the automobile beam frame 4, but at this time, the scraper 1102 has a smaller scraping force on the surface of the automobile beam frame 4, reducing the scraping force of the scraper 1102 on the position where the welding slag has just been knocked off, and at the same time, the uncleaned welding slag scraped off by the scraper 1102 can also be adsorbed and cleaned by the vacuum cleaner 1101;

[0100] The third effect: the clockwise rotation of the diagonal gear 803 drives the counterclockwise rotation of the transmission gear 807. At the same time, the rotating plate 905 connected to the transmission gear 807 drives the hammer 901 to knock downward under the multiple effects of the elastic force of the extrusion spring 907 connected to the slide bar 906 and the elastic force of the buffer spring 903, so that the rotating plate 905 drives the hammer 901 to knock downward, thereby knocking the welded position with a certain force, so that after welding, the welded position is automatically knocked, and the welding slag at the welding position is knocked off and cleaned;

[0101] As the welding machine 3 continues to move from left to right for welding, the rotating sleeve 701 will continue to rotate. After the hammer 901 is knocked down, the top of the abutment rod 805 will continue to slide on the inner wall of the fixed sleeve 801 for a distance and then contact the next protrusion 809. The protrusion 809 squeezes the abutment rod 805, thereby continuing to lift the hammer 901 and move the vacuum cleaner 1101 downward, while driving the cleaning roller 1201 to clean. This movement is repeated to achieve intermittent and synchronous knocking on the welding position during the welding process, and knocking the welding slag after the welding position is cooled for a period of time after welding.

[0102] The welding position can be automatically knocked off the welding slag and cleaned after cooling for a period of time, without the need for manual knocking of the welding position and cleaning of the welding slag, thereby improving the welding efficiency of the automobile beam frame 4 and the cleanliness after welding, and preventing the welding slag from affecting subsequent welding positions.

[0103] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
