Description

Technical Field

[0001] The present application relates to the technical field of box bracket welding, and particularly relates to a triangular iron welding fixture for a box bracket. Background Art

[0002] A triangular iron box bracket is a metal piece used to support and fix a box, usually made of triangular iron, and is used to support and fix various boxes. For example, the box distribution box commonly used in electrical equipment requires the use of a triangular iron box to directly install and protect the distribution box.

[0003] Before welding the triangular iron, it is necessary to clean impurities such as oil stains, rust, and oxide scale on the welding part of the box body of the triangular iron, and place the triangular iron to be welded on the box according to the design requirements, and use a fixture or electric welding for preliminary fixation to prevent displacement during the welding process.

[0004] Referring to the publication number CN220679855U, the theme name is a fixing device for welding an angle steel triangular frame. This device drives a pressing plate and a fixing block to fix the angle steel by using a first motor and a second motor, so as to reduce the offset of the angle steel during welding, and uses a fixing mechanism to fix the outer part of the angle steel to increase the stability of the angle steel during welding.

[0005] For the above technical solution, when welding the triangular iron into a box bracket, due to the differences in boxes, the positions of the welding machines are different. When welding boxes of different sizes, triangular irons of different lengths need to be fixed. Therefore, when welding and fixing triangular irons of different lengths, it is necessary to reposition the triangular irons. When welding the box bracket, the operator needs to press the vertical triangular iron on the already welded triangular iron base, and perform spot welding at the middle position between the vertical triangular iron to be welded and the already welded triangular iron base. When welding the vertical triangular iron to be welded, due to the angle problem of the operator, the welding of the triangular iron may be unstable. Summary of the Invention

[0006] In view of this, the present application provides a triangular iron welding fixture for a box bracket, aiming to solve the problems of welding position offset when welding a triangular iron box bracket and the need to readjust the positioning blocks on the welding plate when welding triangular irons of different lengths.

[0007] A triangular iron welding jig for a box body bracket provided by the present application adopts the following technical solutions, including a bracket and a rotating mechanism; a rotating flap is rotatably connected to the bracket, a first motor is slidably connected to the lateral side wall of the rotating flap, a second motor is slidably connected to the longitudinal side wall of the rotating flap, rotating lead screws are fixedly connected to the output shafts of the first motor and the second motor, one end of each rotating lead screw away from the first motor and the second motor is threadedly connected with a first clamping block, and second clamping blocks are fixedly connected to the first motor and the second motor respectively. Contact baffle plates for abutting against the outer side wall of the triangular iron are fixedly connected to the first clamping block and the second clamping block, and the first clamping block is used to abut against triangular irons of different lengths by following the rotation of the first motor or the second motor.

[0008] Precise control of the motor and the lead screw can make the alignment of the triangular iron before welding more accurate, reduce welding errors, and improve the quality of the welded joint. Since both the movement and positioning are mechanically controlled, it can ensure that the welding position and pressure are relatively consistent each time to a certain extent, thus realizing the consistency and repeatability of welding.

[0009] Optionally, a connecting block is fixedly connected to the rotating flap, and a connecting baffle plate is fixedly connected to the connecting block. The connecting baffle plate is used to abut against the outer side wall of the triangular iron.

[0010] By being applicable to triangular irons of different lengths, it reduces the welding tooling required for triangular irons of a single length, improves the versatility of the equipment. Through the precise control of the motor driving the lead screw, the triangular iron can be moved to the relative position, ensuring that triangular irons of different lengths can be accurately aligned, thus guaranteeing the welding quality.

[0011] Optionally, sliding rods are fixedly connected to the first clamping block and the second clamping block, a vertex clamping block is slidably connected at the intersection of the sliding rods, and vertex clamping blocks are slidably connected at the vertices of the rotating flap far away from the connecting block. The vertex clamping blocks are used to abut against the welding parts of the triangular iron.

[0012] Optionally, clamping cylinders are fixedly connected to the first clamping block and the second clamping block, a clamping plate is fixedly connected to the output shaft of the clamping cylinder, a clamping block is fixedly connected to the clamping plate, a clamping slide rod is slidably connected to the clamping block, a contact roller is rotatably connected to the clamping slide rod, and a contact spring for pushing the clamping slide rod to abut against the side wall of the triangular iron is fixedly connected to the clamping slide rod.

[0013] Optionally, a vertex cylinder is fixedly connected to the connection block and the vertex clamping block.

A push rod spring is fixedly connected to the sliding push rod. A connecting plate is fixedly connected to the end of the sliding push rod away from the abutting block. A connecting roller is rotatably connected to the connecting plate.

[0014] Since the angle iron may be deformed during the welding process, by abutting against the inner side wall and the outer side wall of the angle iron, it can help resist the thermal stress during welding, reduce the deformation of the angle iron during welding, and ensure that the angle iron maintains the correct position and shape during the welding process through support and abutment, thereby maintaining the dimensional accuracy of the welded structure.

[0015] Optionally, a downward moving connecting rod is rotatably connected to one end of the connecting plate close to the abutting block.

A tensioning push block is fixedly connected to the side of the tensioning rod away from the reinforcing plate. The tensioning push block is used to move the angle iron towards the reinforcing plate.

[0019] The vertical angle iron perpendicular to the bottom angle iron can form a more stable structure because this layout can better disperse and bear the forces from all directions. The vertical layout ensures that the load can be evenly transmitted, reduces local stress concentration, and improves the load-bearing capacity of the entire frame.

[0020] Optionally, the rotating mechanism includes a rotating shaft fixedly connected to the side wall of the rotating flap. A rotating motor is fixedly connected to the bracket. The output shaft of the rotating motor is fixedly connected to the rotating shaft.

[0021] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects: 1. Precise control of the motor and the lead screw can make the alignment of the angle iron before welding more accurate, reduce welding errors, and improve the quality of the welded joint. Since both the movement and positioning are mechanically controlled, it can ensure to a certain extent that the welding position and pressure are relatively consistent each time, thus achieving the consistency and repeatability of welding.

Based on the described embodiments of this application, all other embodiments obtained by those of ordinary skill in the art shall fall within the scope of protection of this application.

[0025] As Figure 1 shown, this embodiment provides a triangular iron welding fixture for a box body bracket 1, which includes a bracket 1, a diamond moving mechanism, a vertex mechanism, a clamping mechanism, and a vertex welding mechanism. The bracket 1 is placed on a horizontal plane, and a rotating flap 21 is rotatably connected to the bracket 1. The diamond moving mechanism is used to drive the triangular irons to be welded closer to each other. The vertex mechanism is used to fix the vertex positions of the triangular irons. The clamping mechanism is used to clamp the triangular irons. The vertex welding mechanism is used to fix the vertex positions of the triangular irons to assist in welding.

[0026] As Figure 3 and Figure 5 shown, the diamond moving mechanism includes a first motor 3, a second motor 31, a rotating lead screw 32, a first chuck 33, a second chuck 34, an abutting baffle 35, a connecting slide bar 7, and a connecting sleeve rod 71. The first motor 3 is horizontally slidably connected to the side wall of the rotating flap 21. The second motor 31 is vertically slidably connected to the side wall of the rotating flap 21. There are two rotating lead screws 32, which are respectively fixedly connected to the output shafts of the first motor 3 and the second motor 31. The first chuck 33 is threadedly connected to the rotating lead screws 32 on the first motor 3 and the second motor 31. Second chucks 34 are fixedly connected to both the first motor 3 and the second motor 31. The abutting baffle 35 is fixedly connected to the first chuck 33 and the second chuck 34.

[0027] Place the angle iron to be welded on the first clamping block 33 and the second clamping block 34, and start the first motor 3 to make the output shaft of the first motor 3 rotate, driving the rotating screw rod 32 to rotate. The rotating screw rod 32 drives the first clamping block 33 threadedly connected to the rotating screw rod 32 on the first motor 3 to move towards the first motor 3, and drives the second clamping block 34 on the second motor 31 and the first clamping block 33 on the rotating screw rod 32 of the second motor 31 to move towards the vicinity of the first motor 3. When it moves to the welding position, turn off the first motor 3 and start the second motor 31 to make the second motor 31 drive the rotating screw rod 32 to rotate. The rotating screw rod 32 drives the first clamping block 33 threadedly connected to the rotating screw rod 32 on the second motor 31 to move towards the second motor 31, and drives the second clamping block 34 on the first motor 3 and the first clamping block 33 on the rotating screw rod 32 of the first motor 3 to move towards the vicinity of the second motor 31, so that the angle irons on the first clamping block 33 and the second clamping block 34 are abutted against each other.

[0028] As Figure 1 , Figure 3 , Figure 4 and Figure 6 shown, a sliding groove 72 is formed in the rotating flap 21. A sliding block 73 is fixedly connected to the connecting slide bar 7 and the connecting sleeve bar 71. An auxiliary slide bar 74 is slidably connected to the sliding block 73. The sliding block 73 can slide on the auxiliary slide bar 74, and the auxiliary slide bar 74 can slide on the sliding groove 72.

The vertex clamping block 43 is slidably connected to the sliding rod 42 and is arranged at the intersection position of the sliding rods 42 on the first clamping block 33 and the second clamping block 34.

[0030] When the first motor 3 or the second motor 31 is started, it drives the first clamping block 33 or the second clamping block 34 to move, making the first clamping block 33 and the second clamping block 34 approach each other. During the approaching process, it drives the fixedly connected sliding rod 42 to move, so that the sliding rod 42 drives the vertex clamping blocks 43 at the vertices to approach each other. The vertex clamping block 43 moves towards the end close to the connecting block 4 and fixes the adjacent welded joints of the angle irons.

[0031] As Figure 5 and Figure 10As shown, the clamping mechanism includes a clamping cylinder 5, a clamping plate 51, a clamping block 52, a clamping slide bar 53, a contact roller 54 and a contact spring 55. The clamping cylinder 5 is fixedly connected to the first clamping block 33 and the second clamping block 34. The clamping plate 51 is fixedly connected to the output shaft of the clamping cylinder 5. The clamping block 52 is fixedly connected to the clamping plate 51. The clamping slide bar 53 is slidably connected to the clamping slide bar 53. The contact roller 54 is rotatably connected to the clamping slide bar 53. The contact spring 55 is fixedly connected to the clamping slide bar 53, and one end of the contact spring 55 away from the clamping slide bar 53 is fixedly connected to the clamping block 52.

[0032] When it is necessary to abut against the inner side wall of the angle iron, start the clamping cylinder 5 to move the output shaft of the clamping cylinder 5, and place the angle iron at the middle position between the clamping block 52 and the contact baffle 35. Then, retract the output shaft of the clamping cylinder 5 to drive the clamping plate 51 to move towards the position close to the angle iron, so that the clamping plate 51 drives the clamping block 52 to move towards the inner side wall of the angle iron. When the contact roller 54 abuts against the inner side wall of the angle iron, it pushes the sliding rod 42 to move towards the side away from the inner side wall of the angle iron. When the abutment reaches a certain degree, under the push of the contact spring 55, the contact roller 54 and the contact steel plate clamp the angle iron to reduce the shaking of the angle iron.

[0033] As Figure 7 、 Figure 8 and Figure 9 shown, the apex welding mechanism includes an apex cylinder 6, an apex push block 61, a contact stop block 62, a sliding push rod 63, a push rod spring 64, a connecting plate 65 and a connecting roller 66. The apex cylinder 6 is fixedly connected to the connecting block 4 and the apex clamping block 43. The apex push block 61 is fixedly connected to the output shaft of the apex cylinder 6. The contact stop block 62 is fixedly connected to the apex push block 61 and is used to abut against the inner side walls of two adjacent angle irons. The sliding push rod 63 is slidably connected to the contact stop block 62. The push rod spring 64 is fixedly connected to the sliding push rod 63. The connecting plate 65 is fixedly connected to the sliding push rod 63, and a connecting roller 66 is rotatably connected to the connecting plate 65.

[0034] When it is necessary to fix the welding part of the angle iron, start the apex cylinder 6 to drive the apex push block 61 to move. Before the movement, under the drive of the first motor 3 and the second motor 31, the welding parts of two adjacent angle irons are abutted together. Then, retract the output shaft of the apex cylinder 6 to drive the apex push block 61 to move, so that the contact stop block 62 drives the sliding push rod 63 to move, and the sliding push rod 63 drives the connecting roller 66 on the connecting plate 65 to abut against the inner side wall of the angle iron. After the abutment, the push rod spring 64 is compressed. When the compression reaches a certain degree, under the push of the push rod spring 64, it abuts against the inner side wall of the angle iron.

[0035] AsFigure 9 As shown, one end of the connecting plate 65 close to the abutting stopper 62 is rotatably connected with a downward moving connecting rod 67. One end of the downward moving connecting rod 67 away from the connecting plate 65 is rotatably connected with a lower pressing plate 68. A lower pressing roller 69 is rotatably connected to the lower pressing plate 68.

[0036] When the connecting plate 65 moves towards the side away from the angle iron, it drives the downward moving connecting rod 67 to move, causing the downward moving connecting rod 67 to push the lower pressing plate 68 towards the side close to the bottom wall of the angle iron, so that the lower pressing roller 69 abuts against the bottom wall of the angle iron.

[0037] As Figure 8 shown, a clamping groove 8 is formed in the connecting block 4 and the apex angle clamping block 43. A reinforcing plate 81 is detachably connected in the clamping groove 8. A tension rod 82 is slidably connected to the reinforcing plate 81. A tension spring 83 is fixedly connected to the tension rod 82. A tension pushing block 84 is fixedly connected to the side of the tension rod 82 away from the reinforcing plate 81. The tension pushing block 84 is used to move the angle iron towards the reinforcing plate 81.

[0038] After welding the tripod at the bottom, the reinforcing plate 81 is clamped in the clamping groove 8, and the tension rod 82 is pushed, so that the tension pushing block 84 moves towards the side away from the reinforcing plate 81. The angle iron to be vertically welded is placed in the middle position between the tension pushing block 84 and the reinforcing plate 81. Under the action of the tension spring 83, the tension pushing block 84 is pulled to fix the angle iron, and the vertically placed angle iron and the welded tripod at the bottom are welded together.

[0039] As Figure 1 shown, a rotating mechanism 2 is arranged on the bracket 1. The rotating mechanism 2 includes a rotating shaft 22 fixedly connected to the side wall of the rotating flap 21. A rotating motor 23 is fixedly connected to the bracket 1. The output shaft of the rotating motor 23 is fixedly connected to the rotating shaft 22.

[0040] When this application is in use, place the angle iron to be welded on the first clamping block 33 and the second clamping block 34, and start the first motor 3 to make the output shaft of the first motor 3 rotate, driving the rotating lead screw 32 to rotate. The rotating lead screw 32 drives the first clamping block 33 threadedly connected to the rotating lead screw 32 on the first motor 3 to move towards the first motor 3, and drives the second clamping block 34 on the second motor 31 and the first clamping block 33 on the rotating lead screw 32 of the second motor 31 to move towards the vicinity of the first motor 3. After moving to the welding position, turn off the first motor 3 and start the second motor 31 to make the second motor 31 drive the rotating lead screw 32 to rotate. The rotating lead screw 32 drives the first clamping block 33 threadedly connected to the rotating lead screw 32 on the second motor 31 to move towards the second motor 31, and drives the second clamping block 34 on the first motor 3 and the first clamping block 33 on the rotating lead screw 32 of the first motor 3 to move towards the vicinity of the second motor 31, so that the angle irons located on the first clamping block 33 and the second clamping block 34 are abutted against each other.

[0041] When the first motor 3 or the second motor 31 is started, it drives the first clamping block 33 or the second clamping block 34 to move, making the first clamping block 33 and the second clamping block 34 approach each other. During the approaching process, it drives the fixedly connected sliding rod 42 to move, so that the sliding rod 42 drives the apex clamping blocks 43 located at the apexes to approach each other. The apex clamping blocks 43 move towards one end close to the connecting block 4 and fix the welded part of the adjacent angle irons.

[0042] When it is necessary to abut against the inner side wall of the angle iron, start the clamping cylinder 5 to make the output shaft of the clamping cylinder 5 move, and place the angle iron at the middle position between the clamping block 52 and the abutting baffle 35. Then, retract the output shaft of the clamping cylinder 5 to drive the clamping plate 51 to move towards the position close to the angle iron, so that the clamping plate 51 drives the clamping block 52 to move towards the inner side wall of the angle iron. After the abutting roller 54 abuts against the inner side wall of the angle iron, it pushes the sliding rod 42 to move towards the side away from the inner side wall of the angle iron. After abutting to a certain extent, under the push of the abutting spring 55, the abutting roller 54 and the abutting steel plate clamp the angle iron to reduce the shaking of the angle iron.

[0043] When it is necessary to fix the welded joint of the triangular iron, start the apex angle cylinder 6, so that the apex angle cylinder 6 drives the apex angle push block 61 to move, and before moving, under the drive of the first motor 3 and the second motor 31, make the welded joints of two adjacent triangular irons abut against each other. The output shaft of the apex angle cylinder 6 retracts, drives the apex angle push block 61 to move, so that the abutting stop block 62 drives the sliding push rod 63 to move, and the sliding push rod 63 drives the connecting roller 66 on the connecting plate 65 to abut against the inner side wall of the triangular iron, and after abutting, the push rod spring 64 is compressed. When compressed to a certain extent, under the push of the push rod spring 64, it abuts against the inner side wall of the triangular iron.

[0044] When the connecting plate 65 moves towards the side away from the triangular iron, it drives the downward moving connecting rod 67 to move, so that the downward moving connecting rod 67 pushes the downward pressing plate 68 to move towards the side close to the bottom wall of the triangular iron, and the downward pressing roller 69 abuts against the bottom wall of the triangular iron, and welds the welded joints of the adjacent triangular irons.

[0045] After welding the triangular frame at the bottom, snap the reinforcing plate 81 into the snap groove 8, and push the tension rod 82, so that the tension push block 84 moves towards the side away from the reinforcing plate 81, and place the triangular iron to be vertically welded at the middle position between the tension push block 84 and the reinforcing plate 81. Under the action of the tension spring 83, pull the tension push block 84 to fix the triangular iron, and weld the vertically placed triangular iron and the triangular frame after bottom welding together.

[0046] In this embodiment, the stable apex angle of the triangular iron is ensured by the fixedly connected apex angle clamping block 43, so as to improve the quality of the welded joint, reduce welding defects, and be applicable to triangular irons of different sizes and shapes. By adjusting the apex angle clamping block 43, different welding requirements can be met.

[0047] In this embodiment, fixing the position of the welding apex angle can effectively reduce the thermal deformation during the welding process, and provide additional support for the welding maintenance of the triangular iron, which helps to maintain the original shape of the triangular iron.

[0048] In the embodiment of the present application, the implementation principle of a triangular iron welding fixture for a box body bracket 1 is as follows: Place the triangular iron to be welded on the first clamping block 33 and the second clamping block 34, and start the first motor 3 to rotate the output shaft of the first motor 3, driving the rotating screw rod 32 to rotate. The rotating screw rod 32 drives the first clamping block 33 threaded with the rotating screw rod 32 on the first motor 3 to move towards the first motor 3, and drives the second clamping block 34 on the second motor 31 and the first clamping block 33 on the rotating screw rod 32 of the second motor 31 to move towards the vicinity of the first motor 3. After moving to the welding position, turn off the first motor 3 and start the second motor 31 to drive the rotating screw rod 32 to rotate. The rotating screw rod 32 drives the first clamping block 33 threaded with the rotating screw rod 32 on the second motor 31 to move towards the second motor 3, and drives the second clamping block 34 on the first motor 3 and the first clamping block 33 on the rotating screw rod 32 of the first motor 3 to move towards the vicinity of the second motor 3, causing the triangular irons on the first clamping block 33 and the second clamping block 34 to abut against each other.

[0049] When the first motor 3 or the second motor 31 is started, it drives the first clamping block 33 or the second clamping block 34 to move, causing the first clamping block 33 and the second clamping block 34 to approach each other. During the approaching process, it drives the fixedly connected sliding rod 42 to move, causing the sliding rod 42 to drive the apex clamping blocks 43 at the apexes to approach each other. The apex clamping blocks 43 move towards one end close to the connecting block 4 and fix the welded joints of the adjacent triangular irons.

[0050] When it is necessary to abut against the inner side wall of the triangular iron, start the clamping cylinder 5 to move the output shaft of the clamping cylinder 5, and place the triangular iron at the middle position between the clamping block 52 and the abutting baffle 35. Recover the output shaft of the clamping cylinder 5 to drive the clamping plate 51 to move towards the position close to the triangular iron, causing the clamping plate 51 to drive the clamping block 52 to move towards the inner side wall of the triangular iron. After the abutting roller 54 abuts against the inner side wall of the triangular iron, it pushes the sliding rod 42 to move towards the side away from the inner side wall of the triangular iron. After abutting to a certain extent, under the push of the abutting spring 55, the abutting roller 54 and the abutting steel plate clamp the triangular iron to reduce the shaking of the triangular iron.

[0051] When it is necessary to fix the welded joint of the triangle iron, start the apex angle cylinder 6, so that the apex angle cylinder 6 drives the apex angle push block 61 to move, and before the movement, under the drive of the first motor 3 and the second motor 31, make the welded joints of two adjacent triangle irons abut against each other. The output shaft of the apex angle cylinder 6 retracts, drives the apex angle push block 61 to move, makes the abutting stop block 62 drive the sliding push rod 63 to move, makes the sliding push rod 63 drive the connecting roller 66 on the connecting plate 65 to abut against the inner side wall of the triangle iron, and after the abutment, makes the push rod spring 64 compress. When compressed to a certain extent, under the push of the push rod spring 64, it abuts against the inner side wall of the triangle iron.

[0052] When the connecting plate 65 moves towards the side away from the triangle iron, it drives the downward moving connecting rod 67 to move, makes the downward moving connecting rod 67 push the lower pressing plate 68 to move towards the side close to the bottom wall of the triangle iron, makes the lower pressing roller 69 abut against the bottom wall of the triangle iron, and welds the welded joints of the adjacent triangle irons.

[0053] After welding the triangle frame at the bottom, snap the reinforcing plate 81 into the snap groove 8, and push the tension rod 82, so that the tension push block 84 moves towards the side away from the reinforcing plate 81, and place the triangle iron to be vertically welded at the middle position between the tension push block 84 and the reinforcing plate 81. Under the action of the tension spring 83, pull the tension push block 84 to fix the triangle iron, and weld the vertically placed triangle iron and the triangle frame after bottom welding together.

[0054] The above is the preferred implementation manner of the present application. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle described in the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
