[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a multifunctional welding table for welding metal products, comprising a fixed frame and a metal plate, a driving motor is arranged on the right side of the fixed frame, and also comprises a clamping device; wherein, the clamping device comprises a driving frame, a threaded rod, a limiting sleeve, a clamping plate, a positioning plate, a switching frame, an elastic telescopic rod, a balancing rod and a level, the driving frame is fixedly mounted on the output end of the driving motor, the threaded rod is rotatably mounted on the inner wall of the driving frame, the limiting sleeve is slidably mounted on the circumferential surface of the threaded rod, the clamping plate is threadedly mounted on the circumferential surface of the threaded rod, and the positioning plate is slidably mounted on the surface of the driving frame, The metal plate is placed on the inner wall of the positioning plate, and the positioning plates on both sides position the metal plate under the action of the No. 2 spring. The switching frame is rotatably mounted on the inner wall of the fixed frame, the fixed end of the elastic telescopic rod 1 is fixedly mounted on the surface of the switching frame, the balance rod is fixedly mounted on the movable end of the elastic telescopic rod 1, the level meter is fixedly mounted on the front side of the balance rod, and the metal plate is arranged on the top of the positioning plate. The clamping plate moves to extend the movable end of the elastic telescopic rod 1, and the extension of the movable end of the elastic telescopic rod 1 drives the balance rod to move, and the movement of the balance rod drives the level meter to move. The two are used to detect whether the two sides are level when the threaded rod is manually rotated for clamping; Wherein, a fixing device for auxiliary fixing of the switching frame and a protective device for preventing splashing during welding are arranged on the surface of the fixing frame.

[0007] According to the above technical solution, a No. 1 spring is arranged between the limit sleeve and the driving frame, and the limit sleeve is reset by the No. 1 spring. A No. 2 spring is arranged between the positioning plate and the driving frame, and the positioning plate is reset by the No. 2 spring.

[0008] According to the above technical solution, the fixing device includes a sliding rod, a limit button and a No. 3 spring. The sliding rod is slidably installed on the inner wall of the fixing frame, the limit button is slidably installed on the circumferential surface of the sliding rod, and the No. 3 spring is arranged between the limit button and the sliding rod. The limit button is reset by the arranged No. 3 spring, and the limit button moves by rotating the switching frame and contacting the arc surface of the limit button. The limit button compresses the No. 3 spring while moving. When the switching frame and the limit button are in the same plane, the No. 3 spring is released and drives the limit button to be inserted into the switching frame. At this time, the switching frame is fixed.

[0009] According to the above technical solution, the fixing device also includes a locking rod and an elastic telescopic rod 2. The locking rod is slidably installed on the surface of the fixing frame. A No. 4 spring is arranged between the locking rod and the fixing frame. The locking rod is driven to reset by the arranged No. 4 spring. The fixed end of the elastic telescopic rod 2 is fixedly installed on the surface of the switching frame. The locking rod is used to prevent the sliding rod from being accidentally touched. When the fixation needs to be released, the sliding rod is pulled outward to drive the limit button to disengage from the switching frame.

[0010] According to the above technical solution, the fixing device further includes a support plate and a traction rod. The support plate is fixedly installed at the movable end of the second elastic telescopic rod, and the traction rod is fixedly installed on the top of the support plate. The movement of the second elastic telescopic rod drives the support plate to move, and the movement of the support plate drives the traction rod to move at the same time. The arc surface of the support plate contacts the metal plate.

[0011] According to the above technical solution, the protection device includes a connecting plate, a chute plate, a protection plate and a brake block. The connecting plate is fixedly installed at the rear side of the fixing frame, the chute plate is slidably installed on the inner wall of the connecting plate, the protection plate is slidably installed on the inner wall of the chute plate, the brake block is fixedly installed on the surface of the protection plate close to the metal plate, and a fifth spring is arranged between the protection plate and the chute plate. The fifth spring drives the protection plate to reset. The contact between the outer wall of the metal plate and the brake block causes the protection plate to move, and the movement of the protection plate drives the chute plate to move, and the chute plate moves along the connecting plate.

[0012] According to the above technical solution, the protection device further includes a limit block and a connecting block. The limit block is slidably installed on the surface of the protection plate, and a sixth spring is arranged between the limit block and the protection plate. The sixth spring drives the limit block to reset. The connecting block is fixedly installed on the right side of the limit block, and the bottom of the limit block is set as an inclined surface, so that the limit block disengages from the hollow block.

[0013] According to the above technical solution, the protection device further includes a connecting rod, a traction rope and a hollow block. The connecting rod is rotatably installed on the surface of the connecting block, the traction rope is arranged inside the connecting rod, and the hollow block is fixedly installed on the top of the chute plate. When the traction rope reaches the maximum pulling distance, the connecting rod is pulled to move downward, driving the limit block to disengage from the hollow block. At this time, the fifth spring drives the protection plate to move upward.

[0014] The present invention provides a multifunctional welding table for welding metal products. It has the following beneficial effects: (1) In this invention, through the setting of the clamping device, the metal plate is positioned by the two side positioning plates. Through positioning, the relative position of the metal plate can be ensured to be correct, so that the welding position is at the predetermined position, avoiding the deviation or misalignment of the weld. After the metal plate is positioned, the metal plate is clamped by the clamping plate. The balance rod and the level are used to detect whether both sides are level when manually rotating the threaded rod for clamping. When the two sides of the metal plate are not clamped evenly, during the welding process, due to uneven stress, the metal plate will produce uneven thermal expansion and contraction, resulting in welding deformation. By this method, the stress on the metal plate during welding can be made uniform, reducing the possibility of deformation, and ensuring that the size and shape of the welded metal plate meet the requirements. The driving motor drives the driving frame to rotate, so that the metal plate is turned over, and the limit sleeve is used to prevent the clamping from losing its effect, thus affecting the subsequent welding operation.

[0015] (2) In this invention, through the setting of the fixing device, when welding a metal plate, the bottom of the metal plate is supported by the support plate. The bottom support can provide uniform supporting force, effectively resist the influence of thermal stress, reduce the possibility of deformation, keep the weld seam flat, improve the welding quality. The switching frame is fixed by the limit button to prevent the position of the switching frame from deviating after switching, which may affect the welding operation. The sliding rod is prevented from being accidentally touched by the clamping rod. When it is necessary to release the fixation, the sliding rod can be pulled outwards to drive the limit button to disengage from the switching frame.

[0016] (3) In this invention, through the setting of the protection device, the protection plate is driven to move by the traction rod and the traction rope, so as to block the splash welding slag generated during welding. When protecting metal plates of different sizes, the protection device can adapt to the size of different metal plates through the brake block, improving the applicability of the device.

Detailed Embodiments

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , an embodiment of the present invention is: a multi-functional welding table for welding metal products, including a fixing frame 1 and a metal plate 2. A driving motor is arranged on the right side of the fixing frame 1, and a clamping device is further included; wherein, the clamping device includes a driving frame 3, a threaded rod 4, a limiting sleeve 5, a clamping plate 6, a positioning plate 7, a switching frame 8, a first elastic telescopic rod 9, a balance rod 10 and a level 11. The driving frame 3 is fixedly installed at the output end of the driving motor. The threaded rod 4 is rotatably installed on the inner wall of the driving frame 3. The limiting sleeve 5 is slidably installed on the circumferential surface of the threaded rod 4. The clamping plate 6 is threadedly installed on the circumferential surface of the threaded rod 4. The positioning plate 7 is slidably installed on the surface of the driving frame 3. Through positioning, the relative position of the metal plate 2 can be ensured to be correct, so that the weld is located at a predetermined position, avoiding weld offset or dislocation. The switching frame 8 is rotatably installed on the inner wall of the fixing frame 1. The fixed end of the first elastic telescopic rod 9 is fixedly installed on the surface of the switching frame 8. The balance rod 10 is fixedly installed at the movable end of the first elastic telescopic rod 9. The level 11 is fixedly installed on the front side of the balance rod 10. The metal plate 2 is arranged on the top of the positioning plate 7. When the clamping on both sides of the metal plate 2 is unbalanced, during the welding process, due to uneven force, the metal plate 2 will have uneven thermal expansion and contraction, resulting in welding deformation.

[0021] A first spring is arranged between the limiting sleeve 5 and the driving frame 3, and the first spring drives the limiting sleeve 5 to reset. A second spring is arranged between the positioning plate 7 and the driving frame 3, and the second spring drives the positioning plate 7 to reset.

[0022] During the operation of this embodiment, the metal plate 2 is placed on the inner wall of the positioning plate 7. Under the action of the second spring, the two positioning plates 7 position the metal plate 2. Through positioning, the relative position of the metal plate 2 can be ensured to be correct, so that the weld is located at the predetermined position, avoiding weld offset or misalignment. After the metal plate 2 is positioned, the clamping plates 6 on the upper and lower sides are moved closer to the metal plate 2 by rotating the threaded rod 4 and finally clamp it. The movement of the clamping plate 6 causes the movable end of the first elastic telescopic rod 9 to extend. The extension of the movable end of the first elastic telescopic rod 9 drives the balance rod 10 to move, and the movement of the balance rod 10 drives the level 11 to move. By detecting with these two, it can be determined whether both sides are level when manually rotating the threaded rod 4 for clamping. When the two sides of the metal plate 2 are not clamped evenly, during the welding process, due to uneven force, the metal plate 2 will have uneven thermal expansion and contraction, resulting in welding deformation. By this method, the metal plate 2 can be evenly stressed during welding, reducing the possibility of deformation, and ensuring that the size and shape of the metal plate 2 after welding meet the requirements. When it is necessary to turn over, rotate the switching frame 8 out of the rotation range of the metal plate 2. At this time, the driving motor drives the driving frame 3 to rotate, so that the metal plate 2 is turned over. When the threaded rod 4 is rotated clockwise, the rotation of the threaded rod 4 is limited by the limit sleeve 5, so that the threaded rod 4 cannot rotate, because the threaded rod 4 has no self-locking ability. By this method, the clamping effect is prevented from being lost, thus affecting the subsequent welding operation. When it is necessary to release the clamping, move the limit sleeve 5 downward so that it is out of the rotation range of the threaded rod 4. At this time, the threaded rod 4 can be rotated normally.

[0023] Please refer to Figures 1-8 , on the basis of the above embodiment, in another embodiment of the present invention, a fixing device for assisting in fixing the switching frame 8 and a protection device for preventing spatter during welding are provided on the surface of the fixing frame 1. The fixing device includes a slide rod 20, a limit button 21 and a third spring 22. The slide rod 20 is slidably installed on the inner wall of the fixing frame 1, and the limit button 21 is slidably installed on the circumferential surface of the slide rod 20 to prevent the position of the switching frame 8 from deviating after switching, thus affecting the welding operation. The third spring 22 is arranged between the limit button 21 and the slide rod 20, and the third spring 22 drives the limit button 21 to reset.

[0024] The fixing device further includes a clamping rod 23 and a second elastic telescopic rod 24. The clamping rod 23 is slidably installed on the surface of the fixing frame 1. A fourth spring is arranged between the clamping rod 23 and the fixing frame 1, and the fourth spring drives the clamping rod 23 to reset. The fixed end of the second elastic telescopic rod 24 is fixedly installed on the surface of the switching frame 8, and the clamping rod 23 prevents the slide rod 20 from being accidentally touched.

[0025] The fixing device further includes a support plate 25 and a traction rod 26. The support plate 25 is fixedly installed at the movable end of the second elastic telescopic rod 24, and the traction rod 26 is fixedly installed on the top of the support plate 25. The bottom of the metal plate 2 is supported by the support plate 25. The bottom support can provide uniform support force, effectively resist the influence of thermal stress, reduce the possibility of deformation, keep the weld seam flat, and improve the welding quality.

[0026] The protection device includes a connecting plate 30, a chute plate 31, a protection plate 32 and a brake block 33. The connecting plate 30 is fixedly installed at the rear side of the fixing frame 1. The chute plate 31 is slidably installed on the inner wall of the connecting plate 30, and the protection plate 32 is slidably installed on the inner wall of the chute plate 31. The protection plate 32 blocks the splash welding slag generated during welding. The brake block 33 is fixedly installed on the surface of the protection plate 32 close to the metal plate 2. A fifth spring is arranged between the protection plate 32 and the chute plate 31, and the fifth spring drives the protection plate 32 to reset.

[0027] The protection device further includes a limiting block 34 and a connecting block 35. The limiting block 34 is slidably installed on the surface of the protection plate 32. A sixth spring is arranged between the limiting block 34 and the protection plate 32, and the sixth spring drives the limiting block 34 to reset. The connecting block 35 is fixedly installed on the right side of the limiting block 34. The bottom of the limiting block 34 is set as an inclined surface, and the protection plate 32 is reset manually.

[0028] The protection device further includes a connecting rod 36, a traction rope 37 and a hollow block 38. The connecting rod 36 is rotatably installed on the surface of the connecting block 35. The traction rope 37 is arranged inside the connecting rod 36. The hollow block 38 is fixedly installed on the top of the chute plate 31. Since the traction rod 26 is elastic, when the protection plate 32 drives the traction rope 37 to move, the traction rope 37 is disengaged from the traction rod 26, preventing the position of the support plate 25 from interfering with the operation due to the rising of the protection plate 32.

[0029] During the operation of this embodiment, when welding the metal plate 2, the rotation of the switching frame 8 drives the movement of the second elastic telescopic rod 24. The movement of the second elastic telescopic rod 24 drives the movement of the support plate 25. While the support plate 25 is moving, it drives the movement of the traction rod 26. The arc surface of the support plate 25 contacts the metal plate 2, so that the movable end of the second elastic telescopic rod 24 reaches a distance where it can provide support. At this time, the bottom of the metal plate 2 is supported by the support plate 25. The bottom support can provide uniform support force, effectively resist the influence of thermal stress, reduce the possibility of deformation, keep the weld smooth, improve the welding quality. The rotation of the switching frame 8 contacts the arc surface of the limit button 21, causing the limit button 21 to move. While the limit button 21 is moving, it compresses the third spring 22. When the switching frame 8 and the limit button 21 are in the same plane, the third spring 22 is released and drives the limit button 21 to insert into the switching frame 8. At this time, the switching frame 8 is fixed, preventing the position of the switching frame 8 from deviating after the switching is completed, thus affecting the welding operation. The anti-misoperation of the sliding rod 20 is carried out by the clamping rod 23. When it is necessary to release the fixation, the sliding rod 20 is pulled outwards to drive the limit button 21 to disengage from the switching frame 8; The movement of the traction rod 26 contacts the traction rope 37. When the traction rope 37 reaches the maximum pulling distance, it pulls the connecting rod 36 to move downwards, driving the limit block 34 to disengage from the hollow block 38. At this time, the fifth spring drives the protection plate 32 to move upwards. Because the traction rod 26 has elasticity, when the protection plate 32 drives the traction rope 37 to move, the traction rope 37 disengages from the traction rod 26, preventing the position of the support plate 25 from interfering with the operation due to the upward movement of the protection plate 32. The protection plate 32 blocks the splashed welding slag generated during welding. When protecting metal plates 2 of different sizes, the outer wall of the metal plate 2 contacts the brake block 33, causing the protection plate 32 to move. The movement of the protection plate 32 drives the movement of the chute plate 31. The chute plate 31 moves along the connecting plate 30, enabling the protection device to adapt to the sizes of different metal plates 2 and improving the applicability of the device.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and deformations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
