Description
Technical Field
[0001] This invention relates to the field of welding technology, specifically to a welding device for the production of mechanical supports. Background Technology
[0002] Mechanical supports are devices used to support, fix, or connect mechanical equipment. Mechanical supports are usually made of square tubes welded together. During welding, the square tubes are placed on a fixture and positioned manually before welding. After one side is welded, the support made of square tubes has a preliminary connection. Then the fixture is flipped over and the other side of the support is welded manually.
[0003] Existing supports are composed of multiple square tubes. After welding one side of the support manually, the entire support needs to be flipped over. At this time, the support composed of square tubes is relatively heavy, and manual flipping is physically demanding. Moreover, when the support is not fully welded, the weld points are not secure. During the flipping process, the support collides with the workbench, which can cause vibrations and loosen the weld points, resulting in a decrease in welding quality. Existing automated welding equipment requires sensors and control programs to achieve automated welding, which has high equipment costs and is not conducive to the development of micro-enterprises. Therefore, we propose a welding device for mechanical support production. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, after multiple square tubes are spliced together by the clamping component, the welding component first welds one side of the square tube, and then the flipping component drives the square tube on the clamping component to flip. Since the clamping component is suspended, it will not vibrate due to collision during the flipping process, which would cause the weld to loosen. The positioning component positions and supports the clamping component, ensuring the stability of the clamping component during the welding process.
[0014] In this invention, the positioning component and the flipping component work together to enable the clamping component to unlock and lock the positioning component before and after flipping, thereby simplifying the operation and improving operability.
[0015] In this invention, by using a triggering component and a welding component, the welding gun automatically performs welding when it moves to the weld seam position during the welding process, and stops welding when it leaves the weld seam position. The welding process does not require the intervention of sensors and control systems, which reduces the cost of the welding device and allows the welding gun to automatically avoid interference and collision when it moves to the pull sleeve position, thereby ensuring equipment safety and stable operation of the device.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see Figures 1-11 The present invention provides a technical solution: the welding device for the production of mechanical supports includes a base 1, side beams 11 are fixedly connected to the top two sides of the base 1, a clamping assembly is provided between the two side beams 11, a flipping assembly for flipping the clamping assembly 180 degrees is provided on the opposite side of the side beams 11, a support assembly is provided on the top of the side beams 11, a positioning assembly for positioning the clamping assembly in cooperation with the flipping assembly is provided on the top of the support assembly, a welding assembly is provided on the top side of the support assembly, a triggering assembly for cooperating with the welding assembly is provided on one side of the top of the support assembly, the clamping assembly is composed of a support part and a clamping part, the support part includes a rotating shaft 2 rotatably connected to the inside of the two side beams 11, a support plate 21 is fixedly connected to the opposite end of the two rotating shafts 2, a support platform 22 is fixedly connected to the opposite side of the two support plates 21, a slide 23 is fixedly connected to one side of the top of the support platform 22, and a rotating sleeve 24 is fixedly connected to the other side of the top of the support platform 22; Driven by the flipping component, the clamping component rotates the square tube 180 degrees. Before the flipping action, the positioning component releases the limit on the clamping component. After the flipping action is completed, the positioning component limits the clamping component again and provides stable support and positioning for the clamping component.
[0020] In this embodiment, as Figure 2 , Figure 3 and Figure 7 As shown, the clamping part includes two movable rods 3 slidably connected inside the slide block 23. The opposite ends of the two movable rods 3 are respectively fixedly connected to the pull sleeves 33. The inside of the rotating sleeve 24 is rotatably connected to a bidirectional threaded rod 31 through a bearing. The rotating sleeve 24 is located on the unthreaded section in the middle of the bidirectional threaded rod 31. The two ends of the bidirectional threaded rod 31 are respectively threaded to internal threaded sleeves 32. The opposite ends of the two internal threaded sleeves 32 are respectively fixedly connected to the opposite side of the two pull sleeves 33. The unthreaded section in the middle of the bidirectional threaded rod 31 is fixedly fitted with an anti-slip handle 34. The bottom of both sides of the pull sleeve 33 is fixedly connected to an extended base 35. The end of the extended base 35 away from the pull sleeve 33 is fixedly connected to a baffle 37 for limiting the square tube. The top side of the pull sleeve 33 is formed by bending a bending strip 36. After the clamping assembly is rotated 180 degrees by the flipping assembly, the bending strip 36 is positioned below, thereby supporting the square tube inside the pull sleeve 33; The threads at both ends of the bidirectional threaded rod 31 are left-handed and right-handed, respectively; The square tubes are placed into the support plate 21 and the two pull sleeves 33 respectively. After the two longer square tubes are placed into the pull sleeves 33, the longer square tubes are inserted from the top notch of the pull sleeves 33, and the ends of the square tubes are positioned by the baffles 37. Then, the anti-slip handle 34 is manually rotated to drive the bidirectional threaded rod 31 to rotate, so that the two internal threaded sleeves 32 move closer to the support platform 22. At the same time, the two movable rods 3 retract into the slide 23, thereby allowing the two longer square tubes to clamp the two shorter square tubes on the support plate 21, thus completing the accurate splicing between the square tubes of the mechanical support, which facilitates the accuracy of subsequent welding.
[0021] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the support assembly includes uprights 9 fixedly connected to both sides of the top of each side beam 11, and a support platform 91 is fixedly connected to the top of the four uprights 9. The support platform 91 is used to support the positioning component, welding component and triggering component.
[0022] In this embodiment, as Figure 2 , Figure 9 and Figure 10 As shown, the positioning assembly includes a second support seat 92 fixedly connected to the top two sides of the support platform 91 respectively. The two second support seats 92 are slidably connected to a positioning rod 93 that can move laterally back and forth. The two ends of the positioning rod 93 respectively pass through the two side beams 11. The two support plates 21 are fixedly connected to the opposite corners of the opposite side, and the two ends of the positioning rod 93 can be alternately inserted into the two positioning sleeves 94. The positioning rod 93 consists of two L-shaped rods and a horizontal rod located between the two L-shaped rods. As the positioning rod 93 moves back and forth, its two ends can be alternately inserted into the positioning sleeves 94 of the two support plates 21, thereby improving the stability of the clamping assembly and ensuring stability in the subsequent welding process.
[0023] When one end of the positioning rod 93 is inserted into a positioning sleeve 94, the other end of the positioning rod 93 is away from the other positioning sleeve 94. When both ends of the positioning rod 93 are not inside the positioning sleeve 94, the two ends of the positioning rod 93 are not on the rotation path of the positioning sleeve 94, so it will not hinder the support plate 21 from driving the positioning sleeve 94 to rotate and move.
[0024] In this embodiment, as Figure 5 , Figure 6 and Figure 8 As shown, the flipping assembly consists of a composite drive unit and a transmission unit. The composite drive unit includes a support plate 8 fixedly connected to one side of the base 1. An electric push rod 81 is fixedly connected to the top of the support plate 8. A telescopic sleeve 45 is fixedly connected to the output end of the electric push rod 81. A guide pin 46 is fixedly passed through the outer wall of the telescopic sleeve 45. A cylindrical cam 43 is movably sleeved inside the telescopic sleeve 45. A groove 44 is opened on the outer wall of the cylindrical cam 43, and one end of the guide pin 46 extends into the groove 44, so that the guide pin 46 and the groove 44 slide in cooperation. An extension handle 47 is fixedly connected to the outer wall of the telescopic sleeve 45. The other end of the extension handle 47 is fixedly connected to the positioning rod 93. One of the rotating shafts 2 is fixedly connected to the cylindrical cam 43. The composite drive unit can provide rotational force and lateral force, wherein the rotational force is used to drive the clamping assembly to flip, and the lateral force is used to drive the positioning assembly to position and support the clamping assembly; The slide 44 is composed of a spiral groove and a straight groove connecting the two ends of the spiral groove. The two straight grooves are distributed at 180 degrees around the central axis of the cylindrical cam 43, and the straight grooves extend in the longitudinal direction of the cylindrical cam 43. When the electric push rod 81 drives the telescopic sleeve 45 and guide pin 46 to approach the side beam 11, the guide pin 46 first slides in the straight groove near the electric push rod 81. At this time, the L-shaped rod near the electric push rod 81 slides in the side beam 11 and moves towards the clamping assembly. At the same time, the end of the other L-shaped rod gradually pulls out of the positioning sleeve 94. When the guide pin 46 leaves the straight groove and is about to enter the spiral groove, the other L-shaped rod will completely leave the positioning sleeve 94. After the guide pin 46 enters the spiral groove, it will exert a force on the side wall of the spiral groove, causing the cylindrical cam 43 to rotate. When the guide pin 46 enters the other straight groove, the cylindrical cam 43 completes a 180-degree rotation. During this process, one end of each of the two L-shaped rods is not on the rotation path of the positioning sleeve 94. The clamping assembly is driven to rotate 180 degrees synchronously by the cylindrical cam 43. The specific transmission process is described below. When the guide pin 46 slides in the other straight groove, the end of the L-shaped rod near the electric push rod 81 is inserted into the positioning sleeve 94 near the electric push rod 81 through the extension handle 47.
[0025] In this embodiment, as Figure 4 , Figure 6 and Figure 7 As shown, there are two sets of transmission parts, distributed on the opposite side of the two side beams 11. The transmission part includes an arc groove 4 opened on the opposite side of the two side beams 11, and the arc groove 4 has a span of 180 degrees. An extension rod 42 is fixedly connected to the outer wall of the rotating shaft 2. A limit post 41 is fixedly connected to the side of the extension rod 42 near the side beam 11. The limit post 41 is slidably connected inside the arc groove 4, and the limit post 41 is slidably adapted to the arc groove 4. The cylindrical cam 43 is fixedly connected to one of the rotating shafts 2. When the guide pin 46 slides along the spiral groove, it drives the cylindrical cam 43 to rotate the rotating shaft 2, thereby causing the support plate 21 and the support platform 22 fixedly connected to the rotating shaft 2 to rotate 180 degrees. During the rotation of the support plate 21 and the support platform 22, although the positioning rod 93 also moves, the length of the end of the positioning rod 93 is insufficient to interfere with the positioning sleeve 94. Only when the guide pin 46 slides laterally from the spiral groove into the straight groove can one end of the positioning rod 93 be inserted into the positioning sleeve 94. After the positioning rod 93 is inserted into the positioning sleeve 94, it locks the clamping assembly, thereby ensuring the stability of the clamping assembly and the square tube.
[0026] In this embodiment, as Figure 2 and Figure 10As shown, the welding assembly includes a transverse section and a lifting section. The transverse section includes three first support seats 5 fixedly connected to the top two sides of the support platform 91. A slide rod 51 is fixedly connected between the opposite sides of two of the first support seats 5. A lead screw 54 is rotatably connected to the side of the other first support seat 5 away from the electric push rod 81. A drive motor 52 is fixedly connected to the top of the support platform 91. The output end of the drive motor 52 is fixedly connected to the other end of the lead screw 54. A transverse platform 53 is slidably connected to the outer wall of the slide rod 51, and the lead screw 54 passes through the transverse platform 53 and is threadedly connected to it. The first support base 5 is rotatably connected to the unthreaded end of the lead screw 54 via a bearing. After the drive motor 52 starts, it drives the lead screw 54 to rotate, thereby driving the transverse table 53 to move laterally.
[0027] In this embodiment, as Figure 2 and Figure 10 As shown, the lifting section includes two lifting rods 6 that vertically and movably pass through the transverse platform 53. The bottom of the two lifting rods 6 is fixedly connected to a lower crossbeam 62. Welding guns 64 are fixedly connected to both ends of the lower crossbeam 62. The top of the two lifting rods 6 is fixedly connected to an upper crossbeam 61. A mounting base 66 is fixedly connected to the middle of the bottom of the upper crossbeam 61. A roller 67 is rotatably connected inside the mounting base 66. A guide rod 65 is fixedly connected to the top of the support platform 91. The roller 67 contacts the top of the guide rod 65 under the action of gravity. The lifting rod 6 and the lower crossbeam 62 can be replaced with a telescopic rod fastened with bolts, which allows welding of square tubes of different specifications to improve the applicability of the device. The guide rod 65 consists of a horizontal support, two inclined supports symmetrically connected to both ends of the horizontal support, and L-shaped supports respectively connected to opposite ends of the two inclined supports. The roller 67 moves along the top of the guide rod 65 as the horizontal table 53 moves. When moving from the L-shaped support to the horizontal support, the roller 67 first moves horizontally along the horizontal section of the L-shaped support. Then, when passing the inclined support, it overcomes gravity and causes the welding gun 64 to move upward through the lifting rod 6 and the roller 67, so that the welding gun 64 avoids the support plate 21. The drive motor 52 drives the lead screw 54 to rotate, which causes the transverse table 53 to move the lifting part, thereby enabling the welding gun 64 to perform welding operations. When it is necessary to flip the mechanical support, the welding gun 64 moves to one end of the slide bar 51 or the lead screw 54. At this time, the welding gun 64 will not obstruct the normal rotation of the clamping part and the positioning sleeve 94.
[0028] In this embodiment, as Figure 10 and Figure 11As shown, the triggering assembly includes an extension plate 7 fixedly connected to the bottom of the horizontal moving platform 53 at the end away from the drive motor 52. A pulley 71 is rotatably connected to the top of the extension plate 7. Fixed platforms 72 are fixedly connected to the top two sides of the support platform 91. The fixed platform 72 is composed of a horizontal plate and a vertical plate. Two synchronously moving horizontal moving rods 73 are slidably connected inside the vertical plate. A push plate 74 is connected to the end of the two horizontal moving rods 73 away from the fixed platform 72. A spring 75 is fixedly connected between the push plate 74 and the vertical plate. An insulating plate 76 is fixedly connected to the end of the two horizontal moving rods 73 away from the push plate 74. A first electric plate 77 is fixedly connected to the side of the insulating plate 76 away from the horizontal moving rods 73. An insulating pad 78 is fixedly connected to the top of the horizontal plate. A second electric plate 79 is fixedly connected to the top of the insulating pad 78. The push plate 74 consists of two inclined plates and a flat plate located between the two inclined plates; The pulley 71 and the extension plate 7 move synchronously with the transverse table 53. When the pulley 71 contacts the push plate 74, it slides along the inclined plate of the push plate 74, causing the push plate 74 to overcome the elastic force of the spring 75. The first electric plate 77 and the second electric plate 79 approach each other. When the pulley 71 is about to move from the inclined plate to the flat plate, the pulley 71 pushes the inclined plate first, so that the first electric plate 77 contacts the second electric plate 79. The welding gun 64, which is electrically connected to the first electric plate 77 and the second electric plate 79, is turned on. At this time, the gun head of the welding gun 64 is just aligned with the starting point of the square tube weld and welding is performed. Then the pulley 71 will move to the flat plate position to continue welding along the weld. When the weld is about to be completed, the pulley 71 will separate from the inclined plate position on the other side. At the same time, the first electric plate 77 and the second electric plate 79 separate. At this time, the gun head of the welding gun 64 is located at the end point of the weld.
[0029] The method of use and advantages of the present invention: The welding device for the production of mechanical supports operates as follows: When in use, firstly, manually place multiple square tubes into the tray 21 and two pull sleeves 33 respectively. Then, rotate the anti-slip handle 34, and the two-way threaded rod 31 will drive the two pull sleeves 33 to move closer to each other, so that the square tubes in the pull sleeves 33 clamp the two ends of the square tubes in the tray 21. Then the drive motor 52 is started, and the output end of the drive motor 52 drives the lead screw 54 to rotate, so that the transverse table 53 moves laterally, thereby allowing the welding gun 64 to move laterally. At this time, the roller 67 slides on the horizontal section of the L-shaped bracket. When the pulley 71 pushes the push plate 74, the first electric plate 77 and the second electric plate 79 come into contact and are energized. The welding gun 64 is started and welds the square tube in the support plate 21 and the pull sleeve 33, completing the connection between the square tube on one side of the support plate 21 and the square tube in the two pull sleeves 33. When the roller 67 moves to the inclined bracket of the guide rod 65, the welding gun 64 is raised with the lifting rod 6, and the gun head is away from the clamping assembly to avoid damage to the gun head from impact. When the roller 67 moves from the horizontal bracket to another inclined bracket, the welding gun 64 is lowered with the lifting rod 6, the upper crossbar 61 and the lower crossbeam 62 under the action of gravity, so that the gun head is close to the square tube again. When the pulley 71 passes another push plate 74, the welding gun 64 is started again, so that the square tube on the other support plate 21 and the square tube on the pull sleeve 33 are welded. At this time, the welding of one side has been completed. After welding is completed, the drive motor 52 drives the transverse table 53 to move, and its side abuts against the first support seat 5. At this time, the transverse table 53 reaches the limit of its stroke. At the same time, the lifting rod 6, the lower crossbeam 62 and the welding gun 64 are all located in the gap formed by the side beam 11 and the baffle 37, so that the clamping assembly will not interfere with the welding gun 64 when it is flipped.
[0030] When flipping, the electric push rod 81 is activated, and its output end retracts, driving the telescopic sleeve 45 to move towards the electric push rod 81. At this time, the guide pin 46 will slide laterally in the straight groove on the side of the cylindrical cam 43 away from the electric push rod 81, so that the extension handle 47 moves laterally along with the positioning rod 93. The end of the positioning rod 93 near the electric push rod 81 separates from the positioning sleeve 94 on the corresponding side. When the guide pin 46 slides in the spiral groove, the cylindrical cam 43 drives the rotating shaft 2 to rotate. After rotating 180 degrees, the bending strip 36 is located below, thereby supporting the square tube inside the pull sleeve 33. After the guide pin 46 enters the straight groove of the cylindrical cam 43 near the electric push rod 81, the end of the positioning rod 93 away from the electric push rod 81 is inserted into the positioning sleeve 94 on the corresponding side. Then the drive motor 52 is started in reverse, and the welding gun 64 moves in reverse, so that the welding gun 64 welds the flipped square tube. After welding is completed, the electric push rod 81 is activated in reverse to extend the output end of the electric push rod 81, causing the clamping assembly to flip and reset in the opposite direction. Then, the anti-slip grip 34 is reversed to release the fixation of the pull sleeve 33, thereby allowing the bracket formed by welding the square tube to be removed.
