Description

Technical Field

[0001] This invention relates to the field of bracket welding technology, and more specifically to a welding device for a stage lamp bracket. Background Technology

[0002] Stage lighting is an indispensable and important component of stage performances. Through lighting equipment and technology, it presents a rich and colorful visual feast for the audience. Stage lighting, also known as "stage illumination" or simply "lighting," is one of the means of stage art design. It uses stage lighting equipment (such as lighting fixtures, slides, control systems, etc.) and technical means to display the environment, create atmosphere, highlight central characters, create a sense of stage space and time, shape the external image of the stage performance, and provide necessary lighting effects (such as wind, rain, clouds, water, lightning, etc.) as the plot develops. To facilitate the fixing of stage lights, T-shaped brackets are usually used for auxiliary installation. T-shaped brackets consist of horizontal and vertical plates. To facilitate the fixing of T-shaped brackets, round holes are set on the horizontal plates for bolts to pass through. When welding them, the horizontal plate is first placed flat on the welding table, then the vertical plate is placed on the horizontal plate and fixed. Finally, the horizontal and vertical plates are welded together to form a T-shaped bracket.

[0003] Chinese patent document CN116765720B discloses a bracket welding fixture, including a welding main table, a welding platform mounted on the top of the welding main table, a groove provided on the top of the welding platform, a vertical clamping assembly for clamping a vertical plate provided on the top of the welding platform, and a multi-directional clamping assembly for clamping an inclined plate provided in the groove of the welding platform. The vertical clamping assembly includes a base, a ball screw, a positioning bracket, and a pre-tightening assembly; the multi-directional clamping assembly includes a side plate, a positioning cylinder, a magnetic suction plate, and a placement groove formed on the positioning cylinder.

[0004] When using the tilting plate, first rotate the first handle so that the first handle drives the positioning arc plate to slide to the outside of the opening end of the placement groove through the central connecting shaft. Then, insert one end of the tilting plate into the placement groove and fix it by magnetic suction plate. Then press the other end of the tilting plate to fit against the vertical plate. Then release the first handle so that the first handle drives the central connecting shaft to rotate under the elastic restoring force of the torsion spring, thereby pressing the clamping half ring onto the upper inclined surface of the tilting plate for limiting.

[0005] However, the above-mentioned patent documents also have the following shortcomings: When laser welding is performed at the connection between the horizontal and vertical plates to form a T-shaped bracket, spatter will be generated. These spatter will eventually fall due to gravity. Some of the spatter will easily enter the round hole of the horizontal plate or the edge of the top of the round hole. Because the spatter contains high heat, it is easy for the spatter to adhere to the round hole of the horizontal plate or the edge of the top of the round hole, which will affect the subsequent bolting operation to fix the T-shaped bracket through the round hole. Summary of the Invention

[0006] This invention provides a welding device for a stage lamp bracket, which aims to solve the problem in related technologies where welding slag adheres to the inside of the circular holes in the horizontal plate or at the top edge of the circular holes.

[0007] The welding device for the stage lamp bracket of the present invention includes a control cabinet, a welding mechanism, and a clamping mechanism. The clamping mechanism includes a support part and a pressing part. The support part is rotatable. The device also includes a shielding mechanism including a shielding column, a movable part, an elastic part, a first driving member, and a second driving member. The shielding column is rotatably connected to the support part and can be inserted into a circular hole on a horizontal plate. The movable part is connected to the shielding column through the elastic part. The first driving member is connected to the support part and is used to drive the movable part to extend out of the shielding column and contact the top of the horizontal plate. The second driving member is connected between the shielding column and the control cabinet and is used to drive the shielding column to rotate. The movable part is driven by the shielding column to move along a circular trajectory with the axis of the shielding column as the center.

[0008] Beneficial effects: When the horizontal and vertical plates are welded into a T-shaped bracket by the welding mechanism, the clamping mechanism clamps and fixes the horizontal and vertical plates. At the same time, the shielding column passes through the round hole on the horizontal plate, shielding the round hole and limiting the horizontal plate. Then, the first driving component drives the movable part to extend the shielding column and contact the top of the horizontal plate. The movable part shields the upper edge of the round hole on the upper surface of the horizontal plate. When the support rotates, it drives the horizontal and vertical plates to rotate and drives the shielding column to move along a circular trajectory with the axis of the support as the center. At this time, the second driving component drives the shielding column to rotate. When the shielding column rotates, it drives the movable part to move along a circular trajectory with the axis of the shielding column as the center. This avoids the waste generated during laser welding from adhering to the inner wall of the round hole or the upper edge of the round hole, so as to facilitate the bolts to pass through the round hole and fix the T-shaped bracket.

[0009] Preferably, the shielding post and the circular hole on the horizontal plate are both set to four, and the four shielding posts can be inserted into the four circular holes respectively.

[0010] Its effect is that the four shielding posts can shield the four round holes respectively, so as to prevent waste residue from adhering inside the round holes and affecting the subsequent bolts passing through the round holes.

[0011] Preferably, the movable part and the elastic part are each configured as four groups, with each group containing four movable parts and each group containing four elastic parts. The four groups of movable parts are connected to the four shielding columns through the four groups of elastic parts.

[0012] Its effect is that the four sets of elastic parts can drive the four sets of moving parts to reset.

[0013] Preferably, the first driving component includes a moving part, a second lifting part, and a pushing part. The second lifting part is connected to the support part, the moving part is connected to the telescopic end of the second lifting part, and four pushing parts are provided, all of which are connected to the top of the moving part.

[0014] Its effect is that the lifting part 2 pushes the moving part upward, which can drive the four pushing parts to push the four groups of moving parts respectively, so that the four moving parts in the same group can move in the direction of the extended blocking column, thereby providing power for the movement of the moving parts.

[0015] Preferably, the pushing part is shaped like a frustum conical, and the outer diameter of the pushing part gradually increases from top to bottom.

[0016] Its effect is that, through the frustum-shaped push part, it can avoid the push part from contacting the four moving parts in the same group and affecting the movement of the four moving parts along the circular trajectory.

[0017] Preferably, the second driving component includes an internal gear ring, a connecting arm, and gears. The internal gear ring is connected to the control cabinet through the connecting arm. There are four gears, which are respectively connected to four shielding columns. All four gears are meshed with the internal gear ring.

[0018] Its effect is that when the support rotates, it can drive the four blocking columns to move along a circular trajectory with the axis of the internal gear ring as the center. During this process, the gears on the blocking columns mesh with the internal gear ring, thereby providing power for the rotation of the blocking columns.

[0019] Preferably, the internal toothed ring is coaxially arranged with the support portion.

[0020] Preferably, the distances between the four shielding posts and the support are equal.

[0021] Preferably, the pressing component includes a lifting part, a horizontal arm, and a rotating part. The lifting part is connected to the control cabinet, the horizontal arm is connected to the telescopic end of the lifting part, and the rotating part is rotatably connected to the horizontal arm.

[0022] Its effect is that the lifting part drives the horizontal arm and the rotating part to move down, so that the bottom of the rotating part is in close contact with the top of the vertical plate, thereby clamping and fixing the horizontal and vertical plates to ensure the stability of the horizontal and vertical plates during welding.

[0023] Preferably, the bottom of the rotating part is connected to a limiting part for limiting and supporting the vertical plate.

[0024] The beneficial effects of this invention are:

[0025] 1. The circular hole is blocked by the shielding column, and the horizontal plate is limited. The movable part is driven by the first drive to extend the shielding column and contact the top of the horizontal plate. The movable part blocks the upper edge of the circular hole on the upper surface of the horizontal plate. At the same time, the second drive drives the shielding column to rotate. When the shielding column rotates, it drives the movable part to move along a circular trajectory with the shielding column axis as the center. This is to prevent the waste generated during laser welding from adhering to the inner wall of the circular hole or the upper edge of the circular hole, so as to facilitate the bolt to pass through the circular hole and fix the T-shaped bracket.

[0026] 2. The cone-shaped pusher can prevent the pusher from contacting the four moving parts in the same group and affecting their movement along the circular trajectory. Attached Figure Description

[0035] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] like Figures 1 to 6 As shown, the welding device for the stage light bracket of the present invention includes a control cabinet 1, a welding mechanism 2, a clamping mechanism 3, and a shielding mechanism 6. The welding mechanism 2 and the clamping mechanism 3 are both connected to the control cabinet 1. The clamping mechanism 3 is used to fix the horizontal plate 4 and the vertical plate 5 so that the horizontal plate 4 and the vertical plate 5 can be laser welded to form a T-shaped bracket. The welding mechanism 2 is used to laser weld the contact parts of the horizontal plate 4 and the vertical plate 5 to form a T-shaped bracket. The control cabinet 1 can drive the clamping mechanism 3 to rotate so that the welding mechanism 2 can laser weld the horizontal plate 4 and the vertical plate 5. The shielding mechanism 6 is connected between the control cabinet 1 and the clamping mechanism 3 and is used to shield the inside of the circular hole 41 on the horizontal plate 4 and the edge of the top of the circular hole 41 to prevent residue from adhering to the inside of the circular hole 41 or the edge of the top of the circular hole 41 so that the bolts can pass through the circular hole 41 to fix the T-shaped bracket.

[0037] In use, the horizontal plate 4 and the vertical plate 5 are first placed on the clamping mechanism 3 for clamping, with the horizontal plate 4 placed horizontally and the vertical plate 5 placed vertically. Then, the welding mechanism 2 is started to perform laser welding on the horizontal plate 4 and the vertical plate 5. At the same time, the control cabinet 1 drives the clamping mechanism 3 to rotate the horizontal plate 4 and the vertical plate 5, thereby laser welding the horizontal plate 4 and the vertical plate 5 into a T-shaped bracket. While the horizontal plate 4 and the vertical plate 5 are being laser welded, the shielding mechanism 6 shields the inside of the round hole 41 on the horizontal plate 4 and the edge of the top of the round hole 41, so that the welding slag does not adhere to the round hole 41 or the edge of the top of the round hole 41, so that the bolts can be passed through the round hole 41 to fix and install the T-shaped bracket.

[0038] like Figures 1 to 3As shown, the clamping mechanism 3 includes a support part 31 and a pressing member 32. The support part 31 is rotatably connected to the top of the control cabinet 1. A drive source, which is a motor, is installed inside the control cabinet 1. The output shaft of the motor is connected to the bottom of the support part 31, and the motor can control the rotation of the support part 31. The support part 31 is used to support the horizontal plate 4, and the pressing member 32 is used to limit and support the vertical plate 5. The pressing member 32 includes a lifting part 321, a horizontal arm 322, a rotating part 323, and a limiting part 324. The lifting part 321 is connected to the control cabinet 1 and is a cylinder with its telescopic end facing upwards. The horizontal arm 322... The rotating part 323 is rotatably connected to the horizontal arm 322 and is coaxially arranged with the support part 31 so that the rotating part 323 and the support part 31 can rotate coaxially. The bottom of the rotating part 323 can be in contact with the top of the vertical plate 5, and the rotating part 323 can apply downward pressure to the vertical plate 5 so that the horizontal plate 4 and the vertical plate 5 are in close contact. At the same time, when the support part 31 rotates, it can drive the horizontal plate 4, the vertical plate 5 and the rotating part 323 to rotate. The limiting part 324 is connected to the bottom of the rotating part 323. The limiting part 324 is U-shaped and is used to limit the vertical plate 5.

[0039] In use, the horizontal plate 4 is placed on the support part 31, and then the vertical plate 5 is placed vertically on the support part 31. The vertical plate 5 is limited by the limiting part 324. The lifting part 321 is activated to drive the horizontal arm 322, the rotating part 323 and the limiting part 324 to move down until the bottom of the rotating part 323 is in close contact with the top of the vertical plate 5. Finally, the welding mechanism 2 performs laser welding on the contact part of the horizontal plate 4 and the vertical plate 5 to form a T-shaped bracket.

[0040] like Figures 1 to 6 As shown, the cross-section of the support part 31 is I-shaped. The blocking mechanism 6 includes a blocking post 61, a movable part 62, an elastic part 63, a driving member one, and a driving member two. The blocking post 61 is rotatably connected to the support part 31. The top end of the blocking post 61 extends through to the top of the support part 31, and the bottom end of the blocking post 61 extends into the support part 31. The blocking post 61 is hollow, and an opening is provided at the bottom of the blocking post 61. There are four circular holes 41 and four blocking posts 61. The four blocking posts 61 are configured to cooperate with the four circular holes 41 on the horizontal plate 4. The four blocking posts 61 can block the four circular holes 41 on the horizontal plate 4. Hole 41 is used to block and position the horizontal plate 4. The movable part 62 and the elastic part 63 are both set to four groups. The number of movable parts 62 and elastic parts 63 in each group is set to four. The four groups of movable parts 62 are connected to the four blocking posts 61 through the four groups of elastic parts 63. The top of the outer side of the blocking post 61 is provided with four sockets. The four movable parts 62 in the same group are respectively inserted into the four sockets on the blocking post 61. The four movable parts 62 in the same group are respectively connected to the blocking post 61 through the four elastic parts 63 in the same group. The bottom end of the movable part 62 extends out of the opening at the bottom of the blocking post 61.

[0041] A drive unit 1 is connected to the support 31 and is used to drive the four sets of movable parts 62 to move, so that all four movable parts 62 in the same group move toward the direction of the extended shielding column 61 and contact the top of the horizontal plate 4, thereby shielding the upper edge of the circular hole 41 on the horizontal plate 4. A drive unit 2 is connected to the shielding column 61 and the control cabinet 1 and is used to drive the shielding column 61 to rotate when the support 31 rotates, and the shielding column 61 drives the movable parts 62 to move in a circle around the axis of the shielding column 61, so as to avoid welding slag adhering between the shielding column 61 and the horizontal plate 4 or between the movable parts 62 and the horizontal plate 4, thereby preventing the shielding column 61 from being fixed to the horizontal plate 4 due to welding slag or the movable parts 62 from being fixed to the horizontal plate 4 due to welding slag.

[0042] After the horizontal plate 4 is placed on the support, four shielding posts 61 are inserted into the four round holes 41 on the horizontal plate 4 to position the horizontal plate 4 and prevent it from shifting. After the shielding posts 61 are inserted into the round holes 41, they can shield the inner wall of the round holes 41 to prevent slag from adhering to the inner wall of the round holes 41. In use, the driving component drives the four sets of movable parts 62 to move so that the four movable parts 62 in the same group move towards the direction of the shielding posts 61 and contact the top of the horizontal plate 4. When the support 31 rotates, it drives the shielding posts 61 to rotate, and the shielding posts 61 drive the movable parts 62 to move in a circle around the axis of the shielding posts 61 to prevent welding slag from adhering between the shielding posts 61 and the horizontal plate 4 or between the movable parts 62 and the horizontal plate 4. This prevents the shielding posts 61 from being fixed to the horizontal plate 4 due to welding slag or the movable parts 62 from being fixed to the horizontal plate 4 due to welding slag.

[0043] Continue to refer to Figures 1 to 6 As shown, the drive unit includes a moving part 64, a lifting part 65, and a pushing part 66. The lifting part 65 is connected to the inner bottom wall of the support part 31 and is an electric telescopic rod with its telescopic end facing upwards. The moving part 64 is connected to the telescopic end of the lifting part 65. There are four pushing parts 66, all of which are connected to the top of the moving part 64 and are located directly below the four blocking posts 61. The pushing part 66 is shaped like a frustum of a cone, and its outer diameter extends from top to bottom. The size gradually increases so that when the pushing part 66 moves upward, it can push the four movable parts 62 in the same group to move in the direction of the extending blocking post 61. The four sets of blocking posts 61 squeeze the four sets of elastic parts 63, so that the four movable parts 62 come into contact with the upper edge of the circular hole 41 on the horizontal plate 4, thereby blocking the upper edge of the circular hole 41. At the same time, the truncated cone shape of the pushing part 66 will not affect the rotation of the blocking post 61 or the circular movement of the movable parts 62 around the axis of the blocking post 61.

[0044] Continue to refer to Figures 1 to 6As shown, the distances between the four shielding posts 61 and the support part 31 are equal. The second driving component includes an internal gear ring 67, a connecting arm 68, and gears 69. The internal gear ring 67 is connected to the control cabinet 1 through the connecting arm 68. The internal gear ring 67 is coaxially arranged with the support part 31. There are four gears 69, which are respectively connected to the four shielding posts 61. All four gears 69 are meshed with the internal gear ring 67. When the support part 31 rotates, it drives the four shielding posts 61 to move in a circle with the axis of the support part 31 as the center. At this time, it drives the gears 69 to mesh with the internal gear ring 67 to drive the support part 31 to rotate along its own axis. At the same time, it drives the four sets of movable parts 62 to move in a circle with the axis of the four shielding posts 61 as the center, so as to avoid the welding slag adhering between the shielding posts 61 and the horizontal plate 4 or between the movable parts 62 and the horizontal plate 4, thereby avoiding the shielding posts 61 being fixed to the horizontal plate 4 due to welding slag or the movable parts 62 being fixed to the horizontal plate 4 due to welding slag.

[0045] Working principle:

[0046] Place the horizontal plate 4 on top of the support part 31, and insert the four blocking posts 61 into the four round holes 41 on the horizontal plate 4 respectively, with the tops of the four blocking posts 61 extending out of the tops of the four round holes 41 respectively. Then, place the vertical plate 5 vertically on top of the horizontal plate 4 and fit it against the inner side of the limiting part 324 so that the limiting part 324 limits the vertical plate 5.

[0047] The lifting unit 321 is activated, which drives the pressing part 32, the horizontal arm 322, the rotating part 323 and the limiting part 324 to move down, so that the bottom of the rotating part 323 is in close contact with the top of the horizontal arm 322, thereby achieving the clamping and fixing of the horizontal plate 4 and the vertical plate 5.

[0048] The lifting unit 65 is activated, which drives the moving part 64 and the four pushing parts 66 to move upward. This pushes the four movable parts 62 in the same group to move in the direction of the extending blocking column 61. The four blocking columns 61 then press the four elastic parts 63, so that the four movable parts 62 contact the upper edge of the four round holes 41 on the horizontal plate 4, thereby blocking the upper edge of the four round holes 41.

[0049] The motor inside the control cabinet 1 is started to drive the support part 31 to rotate. When the support part 31 rotates, it drives the horizontal plate 4, the vertical plate 5, the limiting part 324 and the rotating part 323 to rotate. Then, the welding mechanism 2 is started to perform laser welding on the connection position of the horizontal plate 4 and the vertical plate 5 to form a T-shaped bracket. During the laser welding process, the waste residue generated is blocked by four shielding columns 61 and four sets of moving parts 62 so that the waste residue will not adhere to the round hole 41 on the horizontal plate 4 or adhere to the edge of the upper end of the round hole 41.

[0050] When the support part 31 rotates, it drives the four blocking columns 61 to move in a circle around the axis of the support part 31. At this time, it drives the gear 69 to mesh with the internal gear ring 67 to drive the support part 31 to rotate along its own axis. At the same time, it drives the four sets of movable parts 62 to move in a circle around the axis of the four blocking columns 61 respectively.

[0051] After welding is completed, welding mechanism 2 moves away from the formed T-shaped bracket. Then, lifting part 2 65 is activated to drive moving part 64 and four pushing parts 66 to move down and reset. After the four pushing parts 66 separate from the four sets of movable parts 62, the four sets of movable parts 62 lose the thrust of the four pushing parts 66. At this time, under the action of the four sets of elastic parts 63, the four sets of movable parts 62 are driven to reset, so that the four sets of movable parts 62 retract into the four blocking columns 61 respectively.

[0052] Start the lifting unit 321 to move the horizontal arm 322, the rotating part 323 and the limiting part 324 upward, so that the rotating part 323 and the limiting part 324 separate, and finally remove the formed T-shaped bracket.

[0053] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
