Description

Technical Field

[0001] The present invention relates to the technical field of welding jigs, and specifically to a welding jig for sheet metal part processing. Background Art

[0002] A sheet metal part is a product processed through sheet metal technology, which includes various operations such as shearing, punching / cutting / combining, folding, welding, riveting, splicing, and forming. Sheet metal parts are widely used in various fields, such as electronic appliances, communications, the automotive industry, medical devices, aerospace, instrumentation, household appliances, etc. The sheet metal parts can be assembled and fixed by welding to ensure the stability during subsequent use.

[0003] Currently, the patent with the publication number CN218592235U discloses a welding jig for sheet metal part processing, including a bottom frame. The upper surface of the bottom frame is lapped with a top plate. The upper surface of the bottom frame is fixedly connected with a U-shaped frame. Both the left and right sides of the U-shaped frame are fixedly connected with positioning frames. The inner walls of both positioning frames are rotatably connected with lead screws. The side of any positioning frame is fixedly connected with a first motor. The output end of the first motor is fixedly connected with one end of the lead screw. The inner wall of the positioning frame is slidably connected with a movable plate. The opposite surfaces of both movable plates are fixedly connected with connecting rods, and the end of the connecting rod far from the movable plate is fixedly connected with a side clamping plate. Transmission components are installed on the surfaces of both lead screws; when placing the sheet metal part above the top plate and turning on the first motor, the lead screw rotates. At this time, through the first gear, transmission rod, second gear, and chain, the other lead screw is simultaneously driven to rotate synchronously, so as to drive the two movable plates to move towards the opposite surfaces, and drive the side clamping plates to clamp the sheet metal part from the side through the connecting rods. By turning on the second motor and the third motor, the top plate and the pressing plate can be driven to move towards the opposite surfaces through two sets of the same structures, so as to press the sheet metal part from the upper and lower surfaces, thus realizing clamping in different directions, facilitating adjusting the clamping position at will according to the actual situation, and facilitating welding operations at different positions of the sheet metal part.

[0004] However, the following problems still exist during the use of the current welding jig:

[0005] The above-mentioned device places the sheet metal part in a flat manner for welding during use. Therefore, during actual use, when some sheet metal parts need to be adjusted to a specified angle during welding, that is, when it is necessary to adjust the welding angle between two welded sheet metal parts, the sheet metal part cannot be welded stably and standardly at this time.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] See also Figure 1-Figure 9 The present invention provides a technical solution: a welding tool for sheet metal processing, comprising a workbench 1, a fixed plate 2 is symmetrically installed on the upper surface thereof, and a fixed rotating shaft 3 is fixedly installed on the fixed plate 2, a rotating plate 4 is rotatably arranged outside the fixed rotating shaft 3, a supporting plate 5 is fixedly installed on the rotating plate 4, a first motor 6 is fixed at the middle position of the lower end of the workbench 1, a connecting screw 7 is fixedly installed at the output end of the first motor 6, and a connecting sleeve 9 is threadedly connected to the upper end of the connecting screw 7, a first pulley 8 is fixedly installed at the lower end of the connecting screw 7, a pushing plate 10 is fixedly installed at the upper end of the connecting sleeve 9, and the upper end of the pushing plate 10 is fitted with the supporting plate 5, a first sliding groove is opened in the middle position of the workbench 1, and two first guide rods 11 are symmetrically arranged on the left and right sides of the lower surface of the pushing plate 10, and the first guide rod 11 is slidably connected to the workbench 1 through the first sliding groove opened on the workbench 1.

[0030] When it is necessary to adjust the welding angle between the two sheet metal parts, the first motor 6 starts working. Since the output end of the first motor 6 is equipped with a connecting screw 7, the connecting screw 7 starts to rotate at this time, and the connecting screw 7 and the connecting sleeve 9 form a threaded connection. Therefore, with the rotation of the connecting screw 7, the connecting sleeve 9 starts to move upward. Since a pushing plate 10 is installed on the upper end of the connecting sleeve 9, the pushing plate 10 starts to move upward under the action of the first guide rod 11, that is, with the movement of the pushing plate 10, the support plate 5 starts to be pushed. Since a rotating plate 4 is installed on the support plate 5, the rotating plate 4 starts to rotate around the fixed rotating shaft 3 at this time, that is, the support plate 5 starts to have a certain angle with the horizontal plane, and the sheet metal can be placed on the support plate 5 at this time. At this time, there is a certain angle between the two sheet metal parts that need to be welded, so as to realize the welding of sheet metal parts with different angle requirements.

[0031] A second motor 12 is fixedly installed at the lower end of the rotating plate 4, a moving screw 14 is rotatably installed on the rotating plate 4, and the moving screw 14 is rotatably installed on the supporting plate 5, a clamping slider 34 is provided on the moving screw 14, and a clamping plate 35 is fixedly installed on the upper end of the clamping slider 34, an extension plate 18 is fixedly installed on the side of the supporting plate 5, and a supporting screw 17 is rotatably installed on the extension plate 18, and a pressing plate 19 is threadedly connected to the upper end of the supporting screw 17, an electric telescopic rod is fixedly installed at the lower end of the pressing plate 19, and a bonding plate 20 is fixedly installed at the lower end of the electric telescopic rod, a left transverse gear 131 is fixedly installed at the output end of the second motor 12, and a left vertical gear 132 is meshed on the right side of the left transverse gear 131, and the left transverse gear 131 and the left vertical gear 132 form a first gear set 13, the left vertical gear 132 is fixedly installed on the left side of the moving screw 14, and a right transverse gear 151 is fixedly installed on the right side of the moving screw 14, and A right vertical gear 152 is meshed on the right side of the right transverse gear 151, and the right transverse gear 151 and the right vertical gear 152 form a second gear set 15, a second pulley 16 is coaxially installed on the lower end of the right vertical gear 152, and the second pulley 16 is fixedly installed at the lower end of the support screw 17, a first bearing is installed in the middle position of the extension plate 18, and the support screw 17 is rotatably connected with the extension plate 18 through the first bearing installed on the extension plate 18, an adsorption magnet 36 is fixedly installed on the left side of the clamping slider 34, and a third slide bar 40 is fixedly installed on the side of the clamping slider 34, and the third slide bar 40 is slidably connected with the support plate 5, a square groove is provided on the rotating plate 4, and a push spring 37 is fixedly installed in the groove provided on the rotating plate 4, and a push guide plate 38 is fixedly installed on the push spring 37, a positioning rod 39 is fixedly installed on the push guide plate 38, and a cylindrical positioning groove with equal angles is provided on the fixed shaft 3.

[0032] As the sheet metal is placed on the support plate 5, the second motor 12 starts to work. Because the output end of the second motor 12 is connected to the left transverse gear 131, the left transverse gear 131 starts to rotate. Because the left transverse gear 131 is meshed with the left vertical gear 132, the left vertical gear 132 starts to rotate. Because the left vertical gear 132 is installed on the moving screw 14, the moving screw 14 starts to rotate. Because the moving screw 14 is threadedly connected with the clamping slider 34, the clamping slider 34 starts to move. Because the clamping slider 34 is installed with a clamping plate 35, the clamping plate 35 starts to move, so that The placed sheet metal parts are pushed until the two sheet metal parts fit together to facilitate the subsequent welding of the sheet metal parts. As the clamping slider 34 moves, the adsorption magnet 36 installed on the clamping slider 34 also starts to move. At this time, the adsorption magnet 36 starts to move away from the push guide 38, that is, the adsorption magnet 36 no longer adsorbs the push guide 38 (the push guide 38 is set to be an adsorbable iron material, and the push spring 37 is set to be a stainless steel material). At this time, as the adsorption magnet 36 recovers its deformation, the adsorption magnet 36 starts to push the push guide 38 and the positioning rod 39 (when the clamping slider 34 and the clamping plate 35 move towards the direction of the push guide 38). When moving, the push guide plate 38 begins to be moved and adsorbed, that is, the push spring 37 begins to be squeezed and deformed) until the positioning rod 39 fits with the positioning groove provided on the fixed shaft 3. At this time, the fixed shaft 3 and the rotating plate 4 can be positioned and fixed. Because the right transverse gear 151 is installed on the moving screw 14, and because the right transverse gear 151 and the right vertical gear 152 are meshed with each other, the right vertical gear 152 begins to rotate at this time, and because the right vertical gear 152 is coaxially connected with the second pulley 16, the second pulley 16 begins to rotate at this time. Because the second pulley 16 is installed at the lower end of the support screw 17, the support screw 17 begins to rotate at this time. The pressing plate 19 starts to move downward because the supporting screw 17 is connected to the pressing plate 19. The pressing plate 19 starts to move downward because the laminating plate 20 is installed at the lower end of the pressing plate 19. The laminating plate 20 starts to move downward until the laminating plate 20 is tightly fitted with the upper surface of the sheet metal (the pressing plate 19 is installed with an electric telescopic rod at the lower end, and the laminating plate 20 is installed at the lower end of the electric telescopic rod. When different batches of sheet metal need to be welded, the distance between the pressing plate 19 and the laminating plate 20 can be adjusted by the electric telescopic rod, so that different batches of sheet metal can be pressed and fixed). This can effectively prevent the sheet metal from moving or deviating during the welding process.

[0033] A pushing screw 21 is fixedly installed on the upper end of the first pulley 8, a second bearing is installed on the rear side of the workbench 1, and the pushing screw 21 is rotatably connected to the workbench 1 through the second bearing installed on the workbench 1, a receiving plate 22 is threadedly connected to the pushing screw 21, and second guide rods 23 are symmetrically installed on the left and right sides of the lower end of the receiving plate 22, a second slide groove is provided on the rear side of the workbench 1, and the second guide rod 23 is slidably connected to the workbench 1 through the second slide groove provided on the workbench 1, support columns 24 are symmetrically installed on the left and right sides of the upper surface of the receiving plate 22, and an additional plate 25 is fixedly installed on the upper end of the support column 24, a moving motor 26 is fixedly installed on the right side of the additional plate 25, and the output end of the moving motor 26 is connected to the slider screw 27, a support bearing is installed on the upper end of the additional plate 25, and the slider screw 27 is rotatably connected to the additional plate 25 through the support bearing installed on the additional plate 25, A movable slider 28 is slidably provided on the upper end of the mounting plate 25, and a threaded hole is provided in the middle position of the movable slider 28, and the movable slider 28 is connected to the slider screw 27 through the threaded hole, an adjusting motor 29 is fixedly installed on the upper left end of the movable slider 28, a rotating gear 30 is installed on the output end of the adjusting motor 29, and a mounting rack 31 is meshed and connected on the side of the rotating gear 30, a first groove 311 is provided on the right side of the mounting rack 31, and a second groove 312 is provided at the lower end of the mounting rack 31, a second slide bar 33 is fixedly installed in the middle position of the upper end of the movable slider 28, and the second slide bar 33 is slidably connected to the mounting rack 31 through the second groove 312, a first slide bar 32 is fixedly installed on the right side of the upper end of the movable slider 28, and the first slide bar 32 is slidably connected to the mounting rack 31 through the first groove 311, and a welding machine head 41 is fixedly installed at the front side of the mounting rack 31.

[0034] Because the first pulley 8 is fixedly installed at the lower end of the connecting screw 7, the first pulley 8 starts to rotate at this time. Because the first pulley 8 is installed at the lower end of the pushing screw 21, the pushing screw 21 starts to rotate at this time. Because the pushing screw 21 is threadedly connected to the receiving plate 22, the receiving plate 22 starts to move downward under the action of the second guide rod 23. Because the supporting column 24 is installed at the upper end of the receiving plate 22, and the additional plate 25 is fixedly installed on the supporting column 24, the additional plate 25 starts to move downward at this time, that is, the welding head 41 starts to move downward, thereby reducing the height of the welding head 41, which is convenient for subsequent welding processing, and then the mobile motor 26 starts to work, because the output end of the mobile motor 26 is connected to the receiving plate 22. The slider screw 27 is connected to each other. At this time, as the slider screw 27 rotates, the movable slider 28 begins to move, which can drive the welding head 41 to move, so that the welding head 41 moves to the position where the two sheet metal parts are fitted, and then the welding head 41 starts to work, and then the adjusting motor 29 starts to work. Because the output end of the adjusting motor 29 is installed with a rotating gear 30, the rotating gear 30 starts to drive the installation rack 31 to move. With the cooperation of the first groove 311, the second groove 312, the first slide bar 32 and the second slide bar 33, the installation rack 31 can be stably moved, which can drive the welding head 41 to move, so as to realize the welding processing at the position where the two sheet metal parts are fitted.
