[0002] The guide rail positioning welding workbench is a device specially used for welding operations. It mainly uses guide rails to achieve precise positioning and stable support of the workpiece, aiming to improve welding efficiency and welding quality.

[0016] Beneficial Effects

[0017] Compared with the prior art, the present invention provides a new type of guide rail positioning welding workbench, which has the following beneficial effects:

[0018] 1. The new guide rail positioning welding workbench drives the bidirectional screw to rotate by the first motor, and the two sliders and the two L-shaped plates are close to each other. For round pipes, square pipes and tapered pipes, multiple rotating columns can contact the two ends of the pipes. The rotating column rotates to drive the T-shaped column and the movable plate to move until the adjustment block contacts the movable plate, and the end of the T-shaped column away from the connecting block moves to one end of the column groove, and the rotating column is limited in rotation to complete the clamping of the square pipe or round pipe.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] See also Figure 1 , Figure 4 , Figure 6 , Figure 8 and Fig.10 A novel guide rail positioning welding workbench comprises a workbench body 1, a guide rail 11 arranged on the upper surface of the workbench body 1, a slider 12 symmetrically slidably connected to both ends of the guide rail 11, a first motor 13 fixedly connected to the side of the workbench body 1, a bidirectional screw rod 14 fixedly connected to the output shaft of the first motor 13, an L-shaped plate 15 fixedly connected above the slider 12, and a welding assembly 16 arranged on the back of the workbench body 1, the bidirectional screw rod 14 is connected to the two sliders 12 by threads, a clamping mechanism 2 for clamping conical pipe fittings, square pipe fittings and round pipe fittings is arranged on the surface of the L-shaped plate 15, a feeding mechanism 3 for feeding conical pipe fittings, square pipe fittings and round pipe fittings is arranged on the upper surface of the workbench body 1 next to the guide rail 11, and a support plate 4 is symmetrically fixedly connected to the side wall of the workbench body 1;

[0037] The feeding mechanism 3 includes a positioning assembly 31 arranged above the support plate 4 for temporarily placing and positioning conical pipes, square pipes and round pipes, and an adjusting assembly 32 arranged on the side of the L-shaped plate 15 for adjusting the movement of the positioning assembly 31.

[0038] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 The clamping mechanism 2 includes a transverse column 21 rotatably connected to the surface of the L-shaped plate 15, wherein a second motor 22 is fixedly connected to the surface of one of the L-shaped plates 15, and an output shaft of the second motor 22 is fixedly connected to the transverse column 21. The surface of the transverse column 21 is provided with transverse grooves 23 evenly distributed in an annular shape, and a rotating column 24 is installed at one end of the groove wall of multiple transverse grooves 23 away from the L-shaped plate 15 through a torsion spring, and a rectangular groove 25 is provided on the surface of the rotating column 24, and a cylinder 26 is fixedly connected to the groove wall of the rectangular groove 25, and a first spring 27 is sleeved on the outer side of the cylinder 26, and a clamping block 28 is fixedly connected to one end of the first spring 27, and the clamping block 28 is slidably connected to the cylinder 26 and the groove wall of the rectangular groove 25, and the surfaces of multiple rotating columns 24 close to the L-shaped plate 15 are connected by a torsion spring. The force spring is installed with a connecting block 29, and a T-shaped column 210 is symmetrically fixedly connected to the surface of the connecting block 29. A movable plate 211 is installed in cooperation with the wall of the rectangular groove 25. A column groove 212 is symmetrically opened on the surface of the movable plate 211. The T-shaped column 210 is slidably connected to the wall of the column groove 212. A first connecting spring 213 is sleeved on the outer side of the T-shaped column 210. One end of the first connecting spring 213 is fixedly connected to the wall of the column groove 212, and the other end of the first connecting spring 213 is fixedly connected to the end of the T-shaped column 210 away from the connecting block 29. The ends of the walls of the multiple rectangular grooves 25 close to the L-shaped plate 15 are all slidably connected with adjustment blocks 214. The surfaces of the multiple adjustment blocks 214 are rotatably connected with adjustment rings 215, and the adjustment ring 215 is connected to the cross column 21 through threads.

[0039] It should be noted that the first motor 13 drives the bidirectional screw rod 14 to rotate, the two sliders 12 approach each other, and the two L-shaped plates 15 approach each other. For round pipes, square pipes and tapered pipes, multiple rotating columns 24 can contact both ends of the pipes. The rotating column 24 rotates to drive the T-shaped column 210 and the movable plate 211 to move until the adjustment block 214 contacts the movable plate 211, and the end of the T-shaped column 210 away from the connecting block 29 moves to one end of the column groove 212, and the rotating column 24 is rotated to limit the position, so as to complete the clamping of the square pipe or the round pipe. The second motor 22 drives one of the cross columns 2 1 is rotated, and then the pipe fitting is welded. By rotating the adjusting ring 215, the adjusting block 214 can be driven to move on the surface of the transverse groove 23, so that when the end of the T-shaped column 210 away from the connecting block 29 contacts the end surface of the column groove 212 close to the transverse groove 23, the inclination angle of the rotating column 24 compared with the transverse column 21 can be adjusted to increase or decrease, so that it can adapt to clamping pipe fittings of different diameters. According to actual use requirements, when different types of pipe fittings are replaced for welding, there is no need to stop the equipment, and different types of pipe fittings can be quickly switched for welding, thereby improving the overall welding processing efficiency.

[0040] See also Figure 5 , a stopper 216 is fixedly connected to the wall of the rectangular groove 25;

[0041] The setting of the stop block 216 can form a block for the clamping block 28. When the clamping block 28 contacts the two ends of the pipe fitting, that is, when the diameter of the pipe fitting is small, multiple clamping blocks 28 can contact the two ends of the pipe fitting, and relative movement occurs between the clamping block 28 and the cylinder 26 and the rectangular groove 25. The first spring 27 is compressed until the stop block 216 contacts the surface of the clamping block 28, which can ensure that the pipe fitting is stably clamped.

[0042] See also Figure 1 , Figure 2 , Fig.10 and Fig.11The adjusting assembly 32 includes a fixed block 321 fixedly connected to the side of the L-shaped plate 15, a limiting sleeve 322 is symmetrically fixedly connected above the fixed block 321, a first limiting rod 323 is slidably connected to the inner wall of the limiting sleeve 322, a lifting block 324 is fixedly connected above the two first limiting rods 323, a second connecting spring 325 is sleeved on the outer side of the limiting sleeve 322, the upper ends of the two second connecting springs 325 are fixedly connected to the lifting block 324, the lower ends of the two second connecting springs 325 are fixedly connected to the fixed block 321, a limiting column 326 is fixedly connected to the side of the workbench body 1, and the limiting column 326 is fixedly connected to the side of the workbench body 1. The surface of the movable block 327 is symmetrically slidably connected with the movable block 327, and the movable block 327 is installed in cooperation with the lifting block 324. The surface of the movable block 327 is fixedly connected with a return spring 328, and the two return springs 328 are both sleeved on the outside of the limit column 326. The two movable blocks 327 are both slidably connected with the workbench body 1. The upper surface of the workbench body 1 is symmetrically slidably connected with a rack plate 329, and one end of the rack plate 329 is fixedly connected with the movable block 327. The surface of the workbench body 1 is located at the end of the rack plate 329 away from the movable block 327. An inclined block 3210 is fixedly connected, and an inclined groove 3211 is provided on the side of the lifting block 324;

[0043] It should be noted that the adjustment component 32 can adjust the pipe fittings for loading, so that the pipe fittings can be conveyed at the same time during the adjustment and movement of the clamping mechanism 2, thereby completing the clamping. In the process of the two L-shaped plates 15 being adjusted to be close to each other, the fixed block 321 moves with the movement of the L-shaped plate 15. The cooperation of the first limiting rod 323 and the limiting sleeve 322 can ensure the stability of the lifting block 324 when it is adjusted up and down. The elasticity and elasticity of the second connecting spring 325 can facilitate the reset of the lifting block 324 after adjustment. Initially, the lifting block 324 can contact the movable block 327, and the movement of the lifting block 324 can drive the movable block 327 to move. The reset spring 328 is further compressed, and relative movement occurs between the movable block 327 and the limiting column 326. The plate 329 moves with the movable block 327 until the inclined groove 3211 contacts the surface of the inclined block 3210, and the lifting block 324 is adjusted to move upward until it is separated from the movable block 327. The movable block 327 is restored to its initial state under the elastic force of the reset spring 328, and the rack plate 329 is also restored to its initial state. The movement of the rack plate 329 drives the first transmission gear 311 to rotate. When the L-shaped plate 15 is adjusted to move to the initial position, the chamfered plane on the surface of the lifting block 324 can contact the chamfered plane on the surface of the movable block 327 and produce relative movement, so that the lifting plate can move upward, and relative movement occurs between the limiting sleeve 322 and the first limiting rod 323. The second connecting spring 325 is stretched, and the lifting block 324 can be adjusted to the initial position.

[0044] See also Figure 1, the initial state of the return spring 328 is a compressed state;

[0045] It should be noted that the reaction force generated by the compression of the return spring 328 acts on the surface of the movable block 327, so as to facilitate the return of the movable block 327.

[0046] See also Figure 6 , Figure 7 , Fig. 9 , Fig.10 , Fig.12 and Fig.13 The positioning assembly 31 includes a first transmission gear 311 meshedly connected to the top of the rack plate 329, the first transmission gear 311 is rotatably connected to the inclined block 3210, an adjusting column 312 is fixedly connected to the surface of the first transmission gear 311, an L-shaped block 313 is rotatably connected to the end of the surface of the adjusting column 312 close to the first transmission gear 311, and the two L-shaped blocks 313 are fixedly connected to the workbench body 1, a spiral groove 314 is provided on the surface of the adjusting column 312, and a protrusion 315 is installed on the wall of the spiral groove 314, a movable sleeve 316 is sleeved on the outer side of the adjusting column 312, and the protrusion 315 is fixedly connected to the inner wall of the movable sleeve 316, and the upper side of the movable sleeve 316 is meshed with the second transmission gear 31 7. Vertical plates 318 are symmetrically fixedly connected above the support plate 4. Both vertical plates 318 are rotatably connected to the second transmission gear 317. A rack column 319 is meshedly connected above the second transmission gear 317. Both vertical plates 318 are slidably connected to the rack column 319. A top plate 3110 is fixedly connected above the rack column 319. Multiple vertical holes 3111 are provided on the upper surfaces of the two top plates 3110 near the end of the workbench body 1. Lifting columns 3112 are slidably connected to the walls of the vertical holes 3111. Support springs 3113 are sleeved on the outer sides of the lifting columns 3112. A placement plate 3114 is fixedly connected to the upper ends of the four lifting columns 3112. An arc-shaped placement groove 3115 is provided on the upper surface of the placement plate 3114.

[0047] It should be noted that the positioning assembly 31 can temporarily position the pipe. After the rack plate 329 is adjusted and moved, the first transmission gear 311 rotates with the movement of the rack plate 329, and the adjustment column 312 rotates with the rotation of the first transmission gear 311. The protrusion 315 and the spiral groove 314 move relative to each other, driving the movable sleeve 316 to move away from the workbench body 1. The second transmission gear 317 rotates with the movement of the movable sleeve 316, thereby driving the rack column 319 to move, and the top plate 311 rotates. 0 As the rack column 319 moves, the top plate 3110, the placement plate 3114 and the pipe fittings all move toward between the two L-shaped plates 15, that is, in the process of the two L-shaped plates 15 and the clamping mechanism 2 approaching each other, the square pipe fittings, the round pipe fittings or the tapered pipe fittings are fed, so that the automatic feeding of the pipe fittings is completed in the clamping process. The automatic feeding reduces the need for manual intervention, so that the pipe fittings can be quickly and continuously supplied to the welding workbench, reducing the waiting time between processes, thereby further improving the overall welding processing efficiency;

[0048] It should be noted that the arrangement of the lifting column 3112 and the supporting spring 3113 enables the placement plate 3114 to be adjusted and moved up and down. When the pipes to be surface-welded are relatively long, they will be immediately clamped when transported between the two L-shaped plates 15. The elasticity of the supporting spring 3113 can facilitate the reset of the top plate 3110 and the placement plate 3114.

[0049] It should be noted that when the top plate 3110, the placement plate 3114 and the pipe fittings are transported between the two L-shaped plates 15, as the rack plate 329 continues to organize, the first transmission gear 311 continues to rotate, the protrusion 315 and the spiral groove 314 continue to move relative to each other, and the second transmission gear 317 continues to rotate. When the second transmission gear 317 engages with the first rack 3122, it will continuously drive the first rack 3122 and the connecting column 3120 to move in the direction of compressing the third connecting spring 3121. The first rack 3122 will continuously engage, separate, and then engage with the second transmission gear 317, that is, the rotation of the second transmission gear 317 can no longer temporarily adjust the movement of the rack column 319, and the same is true when the rack column 319, the top plate 3110 and the placement plate 3114 are reset. Regardless of whether the first rack 3122 moves toward or away from the rack column 319, the connecting column 3120 is not separated from the circular groove 3119.

[0050] See also Figure 4 A second limiting rod 3116 is fixedly connected to the surface of the L-shaped block 313, one end of the second limiting rod 3116 is fixedly connected to the L-shaped block 313, and the second limiting rod 3116 is slidably connected to the movable sleeve 316;

[0051] It should be noted that the second limiting rod 3116 is configured to limit the movement of the movable sleeve 316. When the adjusting column 312 rotates and relative movement occurs between the protrusion 315 and the spiral groove 314, the movable sleeve 316 cannot rotate along with the adjusting column 312, thereby ensuring the stability of the movable sleeve 316 when being adjusted.

[0052] See also Figure 1 , Figure 4 , Figure 6 , Figure 7 and Fig. 9 , a top block 3117 is fixedly connected to one side of the top plate 3110, an L-shaped column 3118 is fixedly connected to the surface edge of the support plate 4, circular grooves 3119 are provided on both end faces of the rack column 319, a connecting column 3120 is slidably connected to the groove wall of the circular groove 3119, a third connecting spring 3121 is sleeved on the outer side of the connecting column 3120, one end of the third connecting spring 3121 is fixedly connected to the rack column 319, the other end of the third connecting spring 3121 is fixedly connected to the first rack 3122, and the first rack 3122 is fixedly connected to the connecting column 3120;

[0053] It should be noted that the L-shaped column 3118 cooperates with the top block 3117 to form a block for the top plate 3110, so that the placement plate 3114 and the arc-shaped placement groove 3115 and the transported pipe can be adjusted between the two L-shaped plates 15, and the clamping mechanism 2 can clamp the pipe;

[0054] The arrangement of the first rack 3122, the connecting column 3120 and the third connecting spring 3121 can ensure that the top plate 3110 can reach the designated position during the adjustment and movement process, that is, the pipe can be sent to the designated position.
