[0002] A door frame, generally referring to a door pocket, is mainly used for fixing a door leaf, protecting a wall corner, and for decoration purposes. When manufacturing and processing a door frame, generally two groups of metal parts are connected end to end and welded at the joints by a welding device to form a quadrilateral door frame. When welding a door frame, the fixation of the door frame is very important to avoid skewing.

[0003] It is found that the following problems have not been well solved: 1. When welding a door frame, the door frame is formed by splicing and welding loose parts. During the splicing process, even a little inclination deviation can easily cause the subsequent loose parts to be unable to be welded. Therefore, the fixation of the door frame is very important. Manual operation is prone to fatigue, which affects the welding effect; 2. Secondly, during the welding process, workers need to reciprocate to weld the four corners, and some welding points are located inside the door frame. The staff needs to move a lot, which is very easy to cause fatigue and affects the welding efficiency during continuous door frame welding operations. Summary of the Invention

[0012] A method for using a welding device for producing an anti-deformation door frame comprises the following steps: S1. With the start-up of the device, the staff puts the vertical rod and horizontal rod used for the door frame in the lock sleeve and the middle area of ​​the load-bearing plate respectively, and then drives the reduction motor, which drives the double-sided gear through the driving rod, and the double-sided gear meshes with the upper driving plate, thereby driving the upper driving plate to rotate. The upper driving plate continues to rotate, driving the transmission belt on its side to transmit, and the transmission belt outputs power to the transmission wheels on both sides. The transmission wheels synchronously drive the transmission rod to rotate. Since the left rod and the right rod are meshed, when the right rod rotates inward, it can synchronously drive the left rod to move synchronously; S2. As the right and left rods on both sides of the load-bearing plate are retracted inward, the vertical rods can be driven to close to the middle area through the locking sleeves and continuously contact the cross rods. When the vertical rods are in contact with the cross rods, the vertical rods stop moving. At this time, since the right and left rods are provided with a spring telescopic structure, the left and right rods begin to contract and continuously push the locking sleeves to close to the middle area of ​​the vertical rods. S3, then the two locking sleeves close and contact the pressure plate, at this time the pressure rod in the locking sleeve is pressed forward, pushing the wedge plate forward and squeezing the locking plate, the locking plate gradually rises, and the vertical rod is completely locked; The two transmission screw rods are simultaneously contracted and connected to each other, so that the transmission screw rods lose connection with the power storage wheel, and the transmission screw rods are quickly reset through the coil spring, thereby driving the C-shaped sleeves on both sides to move forward relatively, pushing the cross bar frame column on the bearing plate forward continuously, until the cross bar is pushed to the maximum distance, and the cross bar and the vertical rod are in a connected state; S4. At this time, due to the continuous forward movement of the two locking sleeves, the two locking sleeves continue to squeeze the pressure plate and shrink, and then the two locking sleeves squeeze the trigger plate, and the trigger plate pushes the extension plate downward, driving the double-sided gear to engage with the lower drive plate, and the lower drive plate drives the outer ring sleeve through the planetary gear to start to rotate slowly; S5. At the same time, the outer ring sleeve drives the toggle wheel meshing with it, and several toggle wheels are connected by friction belts, so that several toggle wheels rotate synchronously, and the fitting wheels on the side walls of several toggle wheels push the arc plate to perform circular motion in the arc frame, thereby pushing the welding rod to weld the welding point, and the setting of the contact head can control the length of the welding rod when it contacts the material, so as to facilitate precise welding. Finally, when the arc plate completes a circle of rotation, the reduction motor can be controlled to reverse, reset the arc plate, and at the same time push the power storage wheel on the upper drive plate to reverse, push the upper drive plate to reverse and reset all components, so as to facilitate the staff to perform subsequent material collection operations.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by setting the locking parts, transmission screw and power storage wheel on the supporting platform, the four placed metal rods can be automatically arranged and fixed during the operation of the equipment, quickly forming a door frame shape, and the workpiece can be locked, so that the workpiece is not prone to other movements during welding, thereby increasing the welding effect.

[0014] In the present invention, by setting the upper drive plate, the lower drive plate and the bidirectional gear, the power direction can be switched, which reduces the waste of extra power of the equipment, and is also convenient for streamlining the device and reducing the volume, so that the staff can operate it conveniently.

[0015] In the present invention, through the arrangement of the annular frame and the annular plate, when the workpiece is locked, the arc plate can be quickly switched to rotate in the arc frame, and the connection of the workpiece can be welded 360 degrees, which reduces the movement of workers at the four corners of the workpiece, reduces the labor intensity of the workers, and increases the production efficiency during continuous production.

[0025] In this embodiment, Figure 6 , Figure 8 , Fig. 9 and Fig.10 As shown, the transmission mechanism 4 also includes an arc frame 49, the outer wall of the arc frame 49 is fixedly connected to the inner wall of the workbench 1 and the bearing plate 31, the inner wall of the arc frame 49 is slidably connected with an arc plate 410, the inner wall of the arc plate 410 is fixedly connected with a welding rod 411, and the welding rod 411 is a spring telescopic rod structure, and the front end of the welding rod 411 is fixedly connected with a contact head 412, and the top end of the contact head 412 has an arc surface formed by mechanical processing; One side of the arc frame 49 is fixedly connected to a limit plate 413, and a plurality of toggle wheels 414 are arranged in a circular array on the outer wall of the limit plate 413, and the plurality of toggle wheels 414 are connected by a transmission belt 34, and a fitting wheel 415 is fixedly connected to the side walls of the plurality of toggle wheels 414, and the outer wall of the fitting wheel 415 is fitted to the outer wall of the arc plate 410; The side wall of the bottommost toggle wheel 414 on the limiting plate 413 has a helical gear structure formed by machining, and the outer wall of the toggle wheel 414 is meshed with the top of the outer ring sleeve 48, which can control the welding rod 411 to rotate 360 ​​degrees, facilitating rapid welding and reducing the labor intensity of the staff.

[0026] In this embodiment, Figures 1 to 10 As shown, a method for using a welding device for producing an anti-deformation door frame comprises the following steps: S1. With the start of the device, the staff puts the vertical rod and the horizontal rod used for the door frame in the lock sleeve 39 and the middle area of ​​the bearing plate 31 respectively, and then drives the reduction motor, which drives the double-sided gear 44 through the driving rod 2. The double-sided gear 44 meshes with the upper driving plate 32, thereby driving the upper driving plate 32 to rotate. The upper driving plate 32 continues to rotate, driving the transmission belt 34 on its side to transmit. The transmission belt 34 outputs power to the transmission wheels 35 on both sides, and the transmission wheels 35 synchronously drive the transmission rod 36 to rotate. Since the left rod 38 and the right rod 37 are meshed, when the right rod 37 rotates inward, it can synchronously drive the left rod 38 to move synchronously; S2. As the right rod 37 and the left rod 38 on both sides of the bearing plate 31 are retracted inward, the locking sleeve 39 can drive the vertical rod to close to the middle area and continuously contact the cross rod. When the vertical rod and the cross rod are in contact, the vertical rod does not move. At this time, since the right rod 37 and the left rod 38 are set with a spring telescopic structure, the left rod 38 and the right rod 37 begin to contract and continuously push the locking sleeve 39 to close to the middle area of ​​the vertical rod. S3, the two locking sleeves 39 are then closed and contact the pressure plate 318, at which time the pressure rod 396 in the locking sleeve 39 is pressed forward, pushing the wedge plate 393 forward and squeezing the locking plate 395, and the locking plate 395 gradually rises to completely lock the vertical rod; As the upper driving plate 32 continues to rotate, the upper driving plate 32 drives the power storage wheel 313 to rotate continuously. The power storage wheel 313 and the two transmission screws 310 are plugged into each other, so that the power storage wheel 313 can drive the two transmission screws 310 to rotate in the limiting sleeve 311 and continuously store power through the coil spring. When the power storage wheel 313 rotates, the limiting rod 314 on the power storage wheel 313 squeezes the tooth block 312 to contract, so that the power storage wheel 313 can currently only rotate in one direction until the locking sleeve 39 contacts the pressure plate 318, the pressure plate 318 moves inward, compresses the telescopic spring rod, and the pressure plate 318 moves inward. 18 contacts the connecting rod 317 at the same time, and squeezes the two connecting rods 317 arranged opposite to each other inwardly about the shaft rod, at which time the ends of the two connecting rods 317 are in an unfolded state, and the connecting rod 317 pulls the two limiting sleeves 311 away from the power storage wheel 313, and at the same time, the ends of the two transmission screws shrink synchronously, causing the transmission screw to lose connection with the power storage wheel 313, and the transmission screw is quickly reset by the coil spring, thereby driving the C-shaped sleeves on both sides to move forward relatively, and the cross bar frame column on the bearing plate 31 is continuously pushed forward until the cross bar is pushed to the maximum distance, and the cross bar and the vertical bar are in a connected state; S4, at this time, due to the continuous forward movement of the two locking sleeves 39, the two locking sleeves 39 continue to squeeze the pressing plate 318 and shrink, and the two locking sleeves 39 squeeze the trigger plate 46, and the trigger plate 46 pushes the extension plate 45 to move downward, driving the double-sided gear 44 to mesh with the lower driving plate 42, and the lower driving plate 42 drives the outer ring sleeve 48 through the planetary gear 47 to start to rotate slowly; S5. At the same time, the outer ring sleeve 48 drives the toggle wheel 414 meshing with it. Several toggle wheels 414 are connected by friction belts, so that several toggle wheels 414 rotate synchronously. The fitting wheels 415 on the side walls of several toggle wheels 414 push the arc plate 410 to perform circular motion in the arc frame 49, thereby pushing the welding rod 411 to weld the welding point, and the setting of the contact head 412 can control the length of the welding rod 411 when it contacts the material, so as to facilitate precise welding. Finally, when the arc plate 410 completes a circle of rotation, the reduction motor can be controlled to reverse, reset the arc plate 410, and at the same time push the power storage wheel 313 on the upper drive plate 32 to reverse, push the upper drive plate 32 to reverse and reset all components, so as to facilitate the staff to perform subsequent material collection operations.

8. The method for using the welding device for producing anti-deformation door frames according to claim 7, characterized in that: The steps include: S1. With the start-up of the device, the staff places the vertical rod and the horizontal rod used for the door frame in the lock sleeve (39) and the middle area of ​​the bearing plate (31), respectively. At this time, the reduction motor is driven. The reduction motor drives the double-sided gear (44) through the driving rod (2). The double-sided gear (44) is meshed with the upper driving plate (32), thereby driving the upper driving plate (32) to rotate. The upper driving plate (32) continues to rotate, driving the transmission belt (34) on its side to transmit power. The transmission belt (34) outputs power to the transmission wheels (35) on both sides. The transmission wheels (35) synchronously drive the transmission rod (36) to rotate. Since the left rod (38) and the right rod (37) are meshed, when the right rod (37) rotates inward, it can synchronously drive the left rod (38) to move synchronously; S2, as the right rod (37) and the left rod (38) on both sides of the bearing plate (31) are retracted inward, the vertical rod can be driven to close to the middle area through the locking sleeve (39) and continuously contact the cross rod. When the vertical rod and the cross rod are in contact, the vertical rod does not move. At this time, since the right rod (37) and the left rod (38) are provided with a spring telescopic structure, the left rod (38) and the right rod (37) begin to contract and continuously push the locking sleeve (39) to close to the middle area of ​​the vertical rod; S3, the two locking sleeves (39) are then closed and contact the pressure plate (318), at which time the pressure rod (396) in the locking sleeve (39) is pressed forward, pushing the wedge plate (393) forward and squeezing the locking plate (395), so that the locking plate (395) gradually rises and completely locks the vertical rod; As the upper drive plate (32) continuously rotates, the upper drive plate (32) drives the power storage wheel (313) to continuously rotate. The power storage wheel (313) and the two transmission screws (310) are plugged into each other, so that the power storage wheel (313) can drive the two transmission screws (310) to rotate in the limiting sleeve (311) and continuously store power through the coil spring. When the power storage wheel (313) rotates, the limiting rod (314) on the power storage wheel (313) squeezes the tooth block (312) to contract, so that the power storage wheel (313) can currently only rotate in one direction until the locking sleeve (39) contacts the pressure plate (318), and the pressure plate (318) moves inward, compressing and retracting. The spring rod and the pressure plate (318) contact the connecting rod (317) at the same time, and squeeze the two connecting rods (317) arranged in an interlaced manner inwardly about the shaft rod to close. At this time, the ends of the two connecting rods (317) are in an unfolded state, and the connecting rods (317) pull the two limit sleeves (311) away from the power storage wheel (313). At the same time, the ends of the two transmission screw rods are synchronously contracted, causing the transmission screw rod to lose connection with the power storage wheel (313). The transmission screw rod is quickly reset by the coil spring, thereby driving the C-shaped sleeves on both sides to move forward relatively, and the cross bar frame column on the bearing plate (31) is continuously pushed forward until the cross bar is pushed to the maximum distance, and the cross bar and the vertical rod are in a connected state; S4, at this time, due to the continuous forward movement of the two locking sleeves (39), the two locking sleeves (39) continuously squeeze the pressure plate (318) and after the pressure plate (318) contracts, the two locking sleeves (39) squeeze the trigger plate (46), and the trigger plate (46) pushes the extension plate (45) to move downward, driving the double-sided gear (44) to mesh with the lower driving plate (42), and the lower driving plate (42) drives the outer ring sleeve (48) through the planetary gear (47) to start to rotate slowly; S5. At the same time, the outer ring sleeve (48) drives the toggle wheel (414) meshed therewith, and the plurality of toggle wheels (414) are connected by a friction belt, so that the plurality of toggle wheels (414) rotate synchronously, and the fitting wheels (415) on the side walls of the plurality of toggle wheels (414) push the arc plate (410) to perform a circular motion in the arc frame (49), thereby pushing the welding rod (411) to weld the welding point, and the contact head (412) is arranged so that when it contacts the material, the length of the welding rod (411) can be controlled to facilitate precise welding. Finally, when the arc plate (410) completes one circle of rotation, the reduction motor can be controlled to reverse, the arc plate (410) can be reset, and at the same time, the power storage wheel (313) on the upper drive plate (32) can be reversed, and the upper drive plate (32) can be pushed to reverse to reset all components, thereby facilitating the subsequent material taking operation of the staff.
