Description

Technical Field

[0001] This application relates to the field of auxiliary tools for workpiece processing, and in particular to a device for welding the sealing plates of the forklift overhead guard legs. Background Technology

[0002] Forklift overhead guard legs are an important component of the forklift overhead guard structure. Their main function is to support the overhead guard and withstand various forces from above to protect the forklift driver from falling objects. Among them, the bent part of the forklift overhead guard leg is the most important load-bearing part of the entire leg structure.

[0003] In the actual processing of forklift overhead guard legs (hereinafter referred to as legs), a sealing plate needs to be welded to one end face of the legs. Since placing the legs on the ground and welding the sealing plate requires the operator to bend over or squat down, which is very inconvenient and puts a certain physical burden on the operator, it is generally preferred to place the legs on the welding device.

[0004] Reference Figure 1 The welding device typically includes a support base 1 and multiple partitions 2 disposed on the top of the support base 1. The adjacent partitions 2 are spaced apart and form a placement area 21 for placing the support leg 6. By inserting one end of the support leg 6 to be welded to the sealing plate 7 into the placement area 21, the other end of the support leg 6 rests against the ground foundation, so that the support leg 6 can be easily erected to facilitate welding operations on the support leg 6.

[0005] However, in the specific welding process of welding the sealing plate to the outrigger, the operator needs to use one hand to hold the sealing plate against the side end face of the outrigger and use the other hand to hold the welding gun to perform the welding operation. Under this operation method, the welding quality is difficult to guarantee, and the skill level of the operator is relatively high, which needs to be improved. Utility Model Content

[0006] Based on this, this application provides a device for welding the sealing plate of the forklift overhead guard leg, which can fix the sealing plate and keep it against the side end face of the leg to ensure the quality of the welding operation and reduce the dependence on the skill level of the operator.

[0007] The forklift overhead guard support leg sealing plate welding device provided in this application adopts the following technical solution:

[0008] A device for welding the end plates of forklift overhead guard legs includes a support base and multiple partitions disposed on the top of the support base. The partitions are spaced apart to form a placement area for placing the legs. The device also includes a placement seat movably connected to the support base. The placement seat is located below the placement area and is used to place the end plates. A multi-angle adjustment mechanism is provided between the placement seat and the support base to enable the placement seat to rotate freely in the vertical plane. A snap-fit ​​member is elastically connected to the side of the placement seat. The snap-fit ​​member is used to engage with the structural groove at the bottom of the leg to abut the end plate against the side face of the leg.

[0009] By adopting the above-mentioned technical solution, the outrigger sealing plate welding device of this application is fixed to the ground foundation by a support base. When welding the outrigger and the sealing plate, the outrigger is placed in the placement area formed between adjacent partitions, and then the sealing plate is placed on the placement seat. The placement seat and the sealing plate are moved by a multi-angle adjustment mechanism. By matching and locking the snap-fit ​​parts into the structural groove at the bottom of the outrigger, the sealing plate can be tightly abutted against the outrigger. At this time, the operator does not need to use his hands to assist in positioning the sealing plate. It is more conducive to the operator to adjust the position and perform welding operations on the abutment position of the sealing plate and the outrigger in a position that is convenient for him to weld. This ensures the quality of the welding operation and reduces the dependence on the skill level of the operator.

[0010] Optionally, the multi-angle adjustment mechanism includes a suspension rod and a movable rod. The suspension rod is fixedly connected to the support base, and a rotating seat is rotatably mounted on the end of the suspension rod. The rotating seat has a through-hole, and the movable rod is movably inserted into the through-hole. The placement seat is rotatably connected to the end of the movable rod.

[0011] By adopting the above technical solution, by making the movable rod movably inserted into the insertion hole of the rotating seat, the rotation of the rotating seat can make the movable rod move in the vertical plane, and change the insertion position of the movable rod in the insertion hole, thereby adjusting the relative position of the placement seat and the side end face of the support leg, so as to adjust the placement seat to the outside of the support leg, and after the sealing plate is placed in the placement seat, make the sealing plate tightly abut against the side end face of the support leg.

[0012] Optionally, a limiting plate is provided on the side of the placement seat away from the movable rod, and the limiting plate is connected to the placement seat by several connecting posts; the limiting plate is provided with a fitting groove for the sealing plate to be fitted and installed, and when the sealing plate abuts against the side end face of the support leg, the abutting position of the sealing plate and the support leg is directly opposite the connecting post.

[0013] By adopting the above technical solution, when welding the sealing plate and the outrigger, the sealing plate is embedded in the mounting groove, and the sealing plate can be partially exposed in the mounting groove; then, the placement seat is moved by the multi-angle adjustment mechanism so that the sealing plate is tightly against the side end face of the outrigger. At this time, the contact position between the sealing plate and the outrigger can be directly opposite the connecting column, and the operator can easily weld the sealing plate and the outrigger through the gap between the adjacent connecting columns.

[0014] Optionally, the outrigger is a rectangular square steel structure, and the side of the snap-fit ​​component is provided with a snap-fit ​​groove, the thickness of which is adapted to the wall thickness of the outrigger; when the snap-fit ​​component partially enters the structural groove, the outrigger is matched and snapped into the snap-fit ​​groove.

[0015] By adopting the above technical solution and setting a snap-fit ​​groove, when the snap-fit ​​part partially enters the structural groove, the snap-fit ​​part can move towards the placement seat under the action of elastic force, so that the support leg is partially snapped into the snap-fit ​​groove, so as to smoothly and tightly abut the sealing plate against the side end face of the support leg.

[0016] Optionally, the side of the placement base is provided with a sliding groove, and the snap-fit ​​component is slidably installed in the sliding groove; a return spring is provided between the snap-fit ​​component and the inner wall of the sliding groove, and the return spring normally forces the snap-fit ​​component to move towards the placement base.

[0017] By adopting the above technical solution, the reset spring can generate an elastic force acting on the snap-fit ​​component, thereby forcing the snap-fit ​​component to move normally towards the placement seat, so as to force the placement seat to press the sealing plate against the side end face of the support leg, thus facilitating the subsequent welding operation between the sealing plate and the support leg.

[0018] Optionally, a support plate is slidably installed on the side of the placement area, and the sliding direction of the support plate is perpendicular to the arrangement direction of the partition; a connecting rod is fixedly connected to the support plate, and a support seat is provided at the end of the connecting rod away from the support plate, which is used for the support leg to abut against and be placed.

[0019] By adopting the above technical solution, when the outrigger is placed on the support plate, one end of the outrigger can abut against the support seat; after the outrigger and the sealing plate are welded, the outrigger can be moved together by moving the support plate, so that when welding multiple outriggers, the outriggers that have been welded and the outriggers to be welded can be separated, thus improving the convenience of welding operations.

[0020] Optionally, the top surface of the support plate is provided with a polyurethane pad.

[0021] By adopting the above technical solution and setting a polyurethane pad, the outriggers can flexibly contact the polyurethane pad when placed on the support plate, which can reduce the frictional damage to the outriggers when the support plate moves them, thus helping to ensure the forming quality of the outriggers.

[0022] Optionally, a tool tube for placing the welding torch is fixed to the side of the support base.

[0023] By adopting the above technical solution, the tool tube can be used to temporarily place the welding torch during welding operations, so as to facilitate other operations during the welding process and improve operational convenience.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By placing the outriggers in the placement area formed between adjacent partitions, and then placing the sealing plate on the placement seat, the placement seat and sealing plate are moved using a multi-angle adjustment mechanism, and the sealing plate is tightly pressed against the side end face of the outriggers using snap-fit ​​components. This eliminates the need for operators to manually position the sealing plate, ensuring the quality of welding operations and reducing reliance on the skill level of the operators.

[0026] 2. By rotating the rotating seat, the movable rod can be moved in the vertical plane and the insertion position of the movable rod in the insertion hole can be changed. The relative position of the placement seat and the side end face of the support leg can be adjusted so that the placement seat can be adjusted to the outside of the support leg and the sealing plate can be tightly abutted against the side end face of the support leg after the sealing plate is placed in the placement seat.

[0027] 3. By setting up support plates and support seats, after the outriggers are welded to the sealing plate, the outriggers can be moved together by moving the support plate. This allows the welded outriggers to be separated from the outriggers to be welded when welding multiple outriggers, thus improving the convenience of welding operations. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 2-5 This application will be described in further detail.

[0035] This application discloses a device for welding the forklift top guard leg sealing plate.

[0036] Reference Figure 2 A welding device for forklift overhead guard leg end plates includes a support base 1, partitions 2, and a placement seat 3. The support base 1 includes a base frame 11 and a steel beam 12 horizontally arranged on the base frame 11. The support base is placed on the ground foundation via the base frame 11. A tool tube 13 is welded and fixed to the side of the base frame 11 for temporary placement of a welding torch. Multiple partitions 2 are provided, each partition 2 is welded and fixed to the top surface of the steel beam 12, and all partitions 2 are equidistantly arranged along the extension direction of the steel beam 12. A placement area 21 for placing the outriggers 6 is formed between adjacent partitions 2.

[0037] Reference Figure 3 A support plate 5 is slidably disposed inside the placement area 21, and a polyurethane pad 51 is bonded to the top surface of the support plate 5. A plug-in post 52 is fixedly mounted at the bottom of the support plate 5, and a sliding insertion hole 121 is opened on both sides through the steel beam 12. The opening direction of the sliding insertion hole 121 is the same as the extension direction of the steel beam 12, and the inner diameter of the sliding insertion hole 121 is equal to the outer diameter of the plug-in post 52. By inserting the plug-in post 52 into the sliding insertion hole 121, the support plate 5 can slide inside the placement area 21, and the sliding direction of the support plate 5 can be perpendicular to the arrangement direction of the partition 2. In addition, the end of the plug-in post 52 is provided with an anti-detachment part 521 to prevent the plug-in post 52 from directly detaching from the sliding insertion hole 121.

[0038] Simultaneously refer to Figure 2 A connecting rod 53 is fixedly connected to the side of the support plate 5, and a support seat 54 is connected to the end of the connecting rod 53 away from the support plate 5. In this embodiment, by bending the connecting rod 53, the support seat 54 can be normally close to the ground foundation. When the support plate 5 is placed on the support leg 6, the other end face of the support leg 6 away from the end to be welded can abut against the support seat 54. Then, by pushing the support plate 5, the entire support leg 6 can be easily moved together, so that when welding multiple support legs 6, the support leg 6 that has been welded can be separated from the support leg 6 to be welded, thereby improving the convenience of welding operations.

[0039] Reference Figure 4The placement seat 3 is used to place the sealing plate 7, and a multi-angle adjustment mechanism 4 is provided between the placement seat 3 and the steel beam 12. The placement seat 3 is movably connected to the support base 1 through the multi-angle adjustment mechanism 4, so that the placement seat 3 can rotate freely in the vertical plane. The multi-angle adjustment mechanism 4 includes a suspension rod 41 and a movable rod 42. The suspension rod 41 is fixedly connected to the bottom of the steel beam 12, and a rotating seat 411 is rotatably installed at the bottom end of the suspension rod 41. The rotating seat 411 is provided with an axially penetrating insertion hole 412. In this embodiment, the shape of the insertion hole 412 is directional, and the external dimensions of the movable rod 42 are equal to the internal dimensions of the insertion hole 412, so that the movable rod 42 can be inserted into the insertion hole 412 and move within the insertion hole 412.

[0040] The placement seat 3 is rotatably connected to the end of the movable rod 42; at the same time, refer to Figure 5 A limiting plate 31 is provided on the side of the placement seat 3 away from the movable rod 42. The limiting plate 31 is connected to the placement seat 3 by a number of connecting posts 32. In this embodiment, the number of connecting posts 32 is set to 3, but in other feasible embodiments, the number of connecting posts 32 can also be 1, 2 or 4, as long as the limiting plate 31 is stably connected to the placement seat 3. The side of the limiting plate 31 near the movable rod 42 is provided with an insert groove 311. The internal dimensions of the insert groove 311 are equal to the external dimensions of the sealing plate 7, and the thickness of the sealing plate 7 is greater than the depth of the insert groove 311. So when the sealing plate 7 is placed in the insert groove 311, the side of the sealing plate 7 away from the placement seat 3 can be exposed in the insert groove 311.

[0041] Reference Figure 5 The side of the placement base 3 is provided with a sliding groove 33, and a snap-fit ​​component 34 is slidably installed inside the sliding groove 33. A return spring 35 is provided between the snap-fit ​​component 34 and the inner wall of the sliding groove 33. The setting of the return spring 35 makes the snap-fit ​​component 34 elastically connected to the placement base 3, and can normally force the snap-fit ​​component 34 to move closer to the placement base 3. Specifically, the sliding groove 33 extends through one side wall of the placement base 3, and a fastening bolt 36 is threadedly connected to the inner wall of the sliding groove 33. The smooth part of the fastening bolt 36 passes through the snap-fit ​​component 34. The return spring 35 is sleeved on the outer periphery of the fastening bolt 36. One end of the return spring 35 abuts against the bolt end of the fastening bolt 36, and the other end abuts against the snap-fit ​​component 34, thereby generating an elastic force acting on the snap-fit ​​component 34 to force the snap-fit ​​component 34 to normally abut against the inner wall of the sliding groove 33.

[0042] In addition, refer to Figure 4It should be noted that the support leg 6 in this embodiment is a rectangular square steel structure with a hollow interior, and a structural groove 61 is provided at the bottom of the support leg 6; the snap-fit ​​member 34 has a snap-fit ​​groove 341 on the side near the placement seat 3, and the width of the snap-fit ​​groove 341 is set to be equal to the wall thickness of the support leg 6. After the sealing plate 7 is placed in the mounting groove 311, the snap-fit ​​member 34 is partially inserted into the structural groove 61 by moving the placement seat 3, and the support leg 6 is matched and snapped into the snap-fit ​​groove 341. Under the elastic force of the return spring 35, the sealing plate 7 can be forced to tightly abut against the side end face of the support leg 6, and at this time the abutment position of the sealing plate 7 and the support leg 6 can be directly opposite the connecting post 32, which can facilitate the operator to perform welding operations on the sealing plate 7 and the support leg 6 through the gap between the adjacent connecting posts 32.

[0043] The implementation principle of the forklift overhead guard support leg sealing plate welding device in this application embodiment is as follows:

[0044] The welding device for the support leg 6 and the sealing plate 7 is fixed to the ground foundation by the support base 1. When welding the support leg 6 and the sealing plate 7, the support leg 6 is placed in the placement area 21 formed between adjacent partitions 2, and then the sealing plate 7 is placed in the mounting groove 311 of the limiting plate 31. The placement base 3 and the sealing plate 7 are moved by the multi-angle adjustment mechanism 4. The snap-fit ​​part 34 is partially inserted into the structural groove 61, and the support leg 6 is matched and snapped into the snap-fit ​​groove 341. Under the elastic force of the return spring 35, the sealing plate 7 can be tightly pressed against the support leg 6. At this time, the operator does not need to use his hands to assist in positioning the sealing plate 7. It is more conducive to the operator to adjust the position and perform welding operations on the contact position between the sealing plate 7 and the support leg 6 in a position that is convenient for him to weld. This ensures the quality of the welding operation and reduces the dependence on the skill level of the operator.

[0045] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
