Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, in particular to a forklift gantry welding tooling. Background Art

[0002] The various components of the forklift mast need to be combined together. The welding tooling can fix the components so that they will not be displaced or deformed during the welding process, thereby ensuring that the mast meets the design requirements. The positioning and clamping of the tooling can improve the welding quality.

[0003] After searching, the Chinese patent announcement number is: CN217727676U. This utility model belongs to the technical field of forklift door frames, specifically to a tool for welding anti-deformation of forklift door frames, including a rotating rod, a pair of sleeves and a pair of supporting and fixing blocks. Each supporting and fixing block is U-shaped, and the two ends of the rotating rod are correspondingly inserted into the pair of sleeves and threadedly connected to the sleeves. The other end of the pair of sleeves is fixedly connected to one side of the U-shape of the pair of supporting and fixing blocks. The other side of the U-shape of the pair of supporting and fixing blocks is connected with a pair of tightening bolts. The forklift door frame is placed horizontally, and more than four upper The tooling is arranged horizontally and evenly at the lower end of the forklift mast. A pair of channel steel lower side plates of the forklift mast are correspondingly located on a pair of supporting fixing blocks. Each pair of tightening bolts is adjusted to clamp the pair of channel steel lower side plates. Therefore, after the forklift mast is welded, this tooling is used to fix it to control the welding deformation. After the welding is cooled sufficiently, the tooling is removed, thereby effectively controlling the welding deformation of the forklift mast. However, in actual use, when clamping the mast, it is necessary to tighten the bolts of multiple sleeves at the bottom of the mast, which is a relatively cumbersome operation, which increases the workload of the staff and reduces work efficiency. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a forklift mast welding tool, which aims to improve the problem in the prior art that the bolts of multiple sleeves at the bottom of the mast need to be tightened one by one, which is cumbersome to operate and reduces work efficiency.

[0005] The cam is fixedly provided with a toothed connecting strip which is cooperatively connected with the toothed connecting strip, and the toothed connecting strip is meshed with toothed connecting strips.

[0006] Through the above technical solution: when the motor is started, the output end of the motor drives the rotating rod to rotate, and multiple active bevel gears equidistantly fixed to the outer wall of the rotating rod rotate accordingly. Since multiple driven bevel gears are meshed and connected with the corresponding active bevel gears, when the active bevel gear rotates, it will drive the driven bevel gears to rotate, thereby causing the threaded rod to rotate in the hollow column. When the threaded rod rotates, the movable column threadedly connected to it will move along the axial direction of the threaded rod. The left ends of the multiple movable columns are commonly connected to the base plate 2, so when the movable column moves, it will drive the base plate 2 to move relative to the base plate 1. The vertical plates on the top of the base plate 1 and the base plate 2 play the role of supporting the sliding groove. The clamping blocks slidably connected at both ends of the sliding groove can slide in the sliding groove to adjust the position to adapt to forklift masts of different sizes for clamping and fixing.

[0007] As a further description of the above technical solution:

[0008] The hair dryer mechanism includes two movable grooves, which are respectively opened on the left and right sides of the right vertical plate. The top of the right vertical plate is slidably connected to a U-shaped plate, and the right side of the U-shaped plate is fixedly connected to a motor. The output end of the motor passes through the U-shaped plate and is fixedly connected to a roller. The left side of the roller is fixedly connected to an extension plate, and the left side of the extension plate is fixedly connected to a fan.

[0009] The above technical solution: When the motor is started, it drives the roller to rotate. The rotation of the roller provides power for the movement of the entire blower mechanism. Because the left side of the roller is fixedly connected to the extension plate, and the left side of the extension plate is fixedly connected to the fan, when the roller rotates, it drives the extension plate and the fan together. During the welding process of the forklift mast, the fan can move within the range of the movable slot, thereby expanding the blowing range and helping to reduce the temperature of the welding part.

[0010] As a further description of the above technical solution: a plurality of limiting holes are equidistantly provided on the side away from each other of the two vertical plates, and one end of each of the plurality of clamping blocks is rotatably connected to a limiting bolt.

[0011] Through the above technical solution: after the clamping block is adjusted to a suitable position in the sliding groove, the position of the clamping block can be fixed by screwing the limiting bolt into the corresponding limiting hole to ensure that the clamping block does not move during the welding process.

[0012] As a further description of the above technical solution: the two sides of the bottom plate 1 and the bottom plate 2 are fixedly connected with triangular cross plates, and the bottoms of the two triangular cross plates are in contact with the ground.

[0013] Through the above technical solution: the bottom of the triangular horizontal plate fits with the ground, which increases the contact area between the tooling and the ground, disperses the pressure on the tooling, makes the tooling less likely to shake during the welding process, and provides a more stable working platform for welding operations.

[0014] As a further description of the above technical solution: a switch is fixedly connected to the top right side of the bottom plate 1, and the switch is electrically connected to the motor and the motor respectively.

[0015] Through the above technical solution: it is convenient for operators to centrally control the motor and the start and stop of the motor. Through a switch, the motor for adjusting the length of the forklift mast and the motor in the blower mechanism can be controlled, which improves the convenience of operation and work efficiency.

[0016] As a further description of the above technical solution: the bottoms of the bottom plate one and the bottom plate two are both fixedly connected with pads, and the bottoms of the two pads are both fixedly connected with rubber pads.

[0017] Through the above technical solution: the pad can play a role of buffering and protection, reducing the impact of the tooling on the ground during use, and the rubber pad fixedly connected to the bottom of the pad increases the friction between the pad and the ground.

[0018] As a further description of the above technical solution: one end of each of the limiting bolts passes through the limiting hole and is fixedly connected to one side of the corresponding clamping block, and the size of the limiting bolt is consistent with that of the limiting hole.

[0019] Through the above technical solution: one end of the limiting bolt passes through the limiting hole and is fixed to one side of the clamping block, and the limiting bolt is consistent in size with the limiting hole, ensuring that the limiting bolt can fit tightly with the limiting hole.

[0020] As a further description of the above technical solution: sliding grooves are opened on both sides of the interior of the plurality of hollow columns, and sliders are fixedly connected on both sides of the plurality of movable columns, and the plurality of sliders slide inside the corresponding sliding grooves respectively.

[0021] Through the above technical solution: when the moving column moves with the threaded rod, the slider slides in the slide groove, guiding and stabilizing the movement of the moving column, thereby preventing the moving column from deflecting or shaking during the movement.

[0022] The utility model has the following beneficial effects:

[0023] 1. In the utility model, by starting the motor to drive the rotating rod and the active bevel gear to rotate, the threaded rod is rotated in the hollow column, and then the movable column and the bottom plate are driven to move, so that the length of the tooling can be adjusted to adapt to different forklift masts. The vertical plate is used to support the sliding groove, so that the clamping block can be slid to adjust the position and is fixed by the limit bolt to achieve stable clamping of the forklift mast. It only needs to start the motor to drive the overall adjustment to adapt to masts of different sizes, thereby improving work efficiency.

[0024] 2. In the utility model, by starting the motor, the motor output end drives the roller to rotate. Since the roller is fixedly connected to the extension plate and the fan, the fan moves with the roller. During the welding process of the forklift mast, the motor drives the roller to rotate, so that the fan moves within the limited range of the moving groove, expanding the blowing range, realizing the heat dissipation and cooling function, and helping to reduce the temperature of the welding part.

[0033] Reference Figure 1 、 Figure 2 and Figure 3The utility model provides an embodiment of a forklift gantry welding tool, including a base plate 1, which serves as the foundation of the entire tool and provides support for other components. A groove 3 is provided inside the base plate 1 to provide installation space for the transmission part. The front end of the base plate 1 is fixedly connected to a motor 4, which is used to provide power to drive a rotating rod 5 to rotate. The output end of the motor 4 passes through the base plate 1 and is fixedly connected to a rotating rod 5. The rotating rod 5 is used to drive the active bevel gear 6 to rotate. The outer wall of the rotating rod 5 is fixedly connected to multiple active bevel gears 6 at equal intervals. The driving bevel gear 6 cooperates with the driven bevel gear 9 to realize transmission. A plurality of hollow columns 7 are fixedly connected at equal distances on the left side of the bottom plate 1. The hollow columns 7 provide support and rotation space for the threaded rod 8. The interiors of the plurality of hollow columns 7 are rotatably connected with the threaded rod 8. The threaded rod 8 drives the moving column 10 to move when it rotates. The right ends of the plurality of threaded rods 8 pass through the groove 3 and are fixedly connected with the driven bevel gear 9. The driven bevel gear 9 rotates under the drive of the driving bevel gear 6. The plurality of driven bevel gears 9 are meshed with the corresponding driving bevel gear 6. The outer wall is threadedly connected with a moving column 10. The moving column 10 moves with the rotation of the threaded rod 8, thereby driving the bottom plate 2 11 to move.

The tooling length can be adjusted to adapt to different forklift door frames. The tops of the bottom plate 2 11 and the bottom plate 1 1 are fixedly connected with a vertical plate 12.

A blower mechanism 2 is provided on the top of the bottom plate 1, and the blower mechanism 2 can dissipate heat and remove welding smoke. A plurality of limiting holes 17 are equidistantly provided on the side away from each other of the two vertical plates 12. The limiting holes 17 cooperate with the limiting bolts 18 to fix the position of the clamping block 14. One end of the plurality of clamping blocks 14 is rotatably connected to the limiting bolt 18, and the limiting bolt 18 can fix the clamping block 14 in the desired position.

[0034] Specifically, when using the forklift gantry welding fixture, the motor 4 is started to drive the rotating rod 5 to rotate, and the multiple active bevel gears 6 fixedly connected to the outer wall of the rotating rod 5 at equal distances rotate accordingly. Since the multiple driven bevel gears 9 are meshed and connected with the corresponding active bevel gears 6, when the active bevel gear 6 rotates, it will drive the driven bevel gear 9 to rotate. The driven bevel gear 9 is fixed to the right end of the threaded rod 8, thereby causing the threaded rod 8 to rotate in the hollow column 7. When the threaded rod 8 rotates, the moving column 10 threadedly connected thereto will move along the axial direction of the threaded rod 8. The left ends of the multiple moving columns 10 are commonly connected to the bottom plate 2 11, so when the moving column 1 When 0 moves, it will drive the bottom plate 2 11 to move relative to the bottom plate 1 1. The bottom plate 1 1 and the vertical plate 12 on the top of the bottom plate 2 11 play the role of supporting the sliding groove 13. The clamping blocks 14 slidably connected at both ends of the sliding groove 13 can slide in the sliding groove 13 to adjust the position to adapt to forklift masts of different sizes for clamping and fixing. When the clamping block 14 is adjusted to a suitable position in the sliding groove 13, the position of the clamping block 14 can be fixed by turning the limit bolt 18 into the corresponding limit hole 17 to ensure that the clamping block 14 will not move during the welding process, thereby stably clamping the forklift mast and ensuring the accuracy of welding.

[0035] Reference Figure 1 and Figure 4 The hair dryer mechanism 2 includes two movable grooves 201, which are respectively opened on the left and right sides of the right vertical plate 12. The top of the right vertical plate 12 is slidably connected with a U-shaped plate 202. The U-shaped plate 202 is used to install a motor 203 and a connecting roller 204. The right side of the U-shaped plate 202 is fixedly connected with a motor 203. The motor 203 is used to provide power to drive the roller 204 to rotate. The output end of the motor 203 passes through the U-shaped plate 202 and is fixedly connected to the roller 204. The roller 204 is used to drive the extension plate 205 and the fan 206 to move. The left side of the roller 204 is fixedly connected to an extension plate 205, which is used to connect the roller 204 and the fan 206. The left side of the extension plate 205 is fixedly connected to the fan 206, which is used to dissipate heat and remove welding smoke. A plurality of limiting holes 17 are equidistantly provided on the opposite side of the two vertical plates 12. The limiting holes 17 cooperate with the limiting bolts 18 to fix the position of the clamping block 14. One end of the plurality of clamping blocks 14 is rotatably connected to the limiting bolts 18, which can fix the clamping block 14 in the desired position.

[0036] Specifically, when the motor 203 is started, the output end of the motor 203 drives the roller 204 to rotate. Since the left side of the roller 204 is fixedly connected to the extension plate 205, and the left side of the extension plate 205 is fixedly connected to the fan 206, when the roller 204 rotates, it will drive the extension plate 205 and the fan 206 to move together. During the welding process of the forklift mast, the roller 204 is driven to rotate by the motor 203, so that the fan 206 can move within the range limited by the movable groove 201, thereby expanding the range of blowing air and helping to reduce the temperature of the welding part.

[0037] Reference Figure 1 and Figure 2 , the sides away from the bottom plate 1 and the bottom plate 2 11 are fixedly connected with a triangular horizontal plate 19, the triangular horizontal plate 19 is used to enhance the stability of the tooling, the bottoms of the two triangular horizontal plates 19 are in contact with the ground, the top right side of the bottom plate 1 is fixedly connected with a switch 20, the switch 20 is used to control the start and stop of the motor 4 and the motor 203, the switch 20 is electrically connected to the motor 4 and the motor 203 respectively, the bottom of the bottom plate 1 and the bottom of the bottom plate 2 11 are fixedly connected with a pad 21, the pad 21 is used for buffering and protection, the bottom of the two pads 21 are fixedly connected with a rubber pad 22, the rubber pad 22 is used to increase friction and buffering;

[0038] Specifically, the bottom of the triangular horizontal plate 19 fits with the ground, which increases the contact area between the tooling and the ground, disperses the pressure on the tooling, and makes the tooling less likely to shake during welding, providing a more stable working platform for welding operations, and facilitating the operator to centrally control the start and stop of the motor 4 and the motor 203. The motor 4 for adjusting the length of the forklift mast and the motor 203 in the blower mechanism 2 can be controlled by the switch 20, thereby improving the convenience of operation and work efficiency. The rubber pad 22 fixedly connected to the bottom of the pad 21 further enhances the buffering effect, and can also increase the friction between the ground to prevent the tooling from sliding during welding.

[0039] Reference Figure 2 and Figure 3, one end of multiple limiting bolts 18 passes through the limiting holes 17 and is fixedly connected to one side of the corresponding clamping block 14, the limiting bolts 18 are used to fix the clamping block 14 in the required position, the limiting bolts 18 are consistent with the size of the limiting holes 17 to ensure the fixing effect, the away side of the bottom plate 1 and the bottom plate 2 11 are fixedly connected with a triangular cross plate 19, the triangular cross plate 19 is used to enhance the stability of the tooling, the bottoms of the two triangular cross plates 19 are in contact with the ground, a switch 20 is fixedly connected to the top right side of the bottom plate 1, the switch 20 is used to control the start and stop of the motor 4 and the motor 203, the switch 20 is electrically connected to the motor 4 and the motor 203 respectively, the bottom of the bottom plate 1 and the bottom of the bottom plate 2 11 are fixedly connected with a pad 21, the pad 21 is used for buffering and protection, the bottom of the two pads 21 are fixedly connected with a rubber pad 22, the rubber pad 22 is used to increase friction and buffering;

[0040] Specifically, the limiting bolt 18 is consistent in size with the limiting hole 17, ensuring that the limiting bolt 18 can fit tightly with the limiting hole 17, which further strengthens the fixing effect of the clamping block 14. The sliding grooves 15 on both sides of the hollow column 7 are used in conjunction with the sliders 16 fixedly connected to both sides of the movable column 10. When the movable column 10 moves along with the threaded rod 8, the sliders 16 slide in the sliding grooves 15, guiding and stabilizing the movement of the movable column 10, thereby preventing the movable column 10 from deflecting or shaking during movement.

[0041] Working principle: When using the forklift gantry welding fixture, the motor 4 is started and the rotating rod 5 is driven to rotate, and the multiple active bevel gears 6 fixedly connected to the outer wall of the rotating rod 5 at equal distances rotate accordingly. Since the multiple driven bevel gears 9 are meshed and connected with the corresponding active bevel gear 6, when the active bevel gear 6 rotates, it will drive the driven bevel gear 9 to rotate. The driven bevel gear 9 is fixed to the right end of the threaded rod 8, thereby causing the threaded rod 8 to rotate in the hollow column 7. When the threaded rod 8 rotates, the moving column 10 threadedly connected thereto will move along the axial direction of the threaded rod 8. The left ends of the multiple moving columns 10 are commonly connected to the bottom plate 2 11, so when the moving column 10 moves, it will drive the bottom plate 2 11 to move relative to the bottom plate 1 1. The vertical plates 12 on the top of the bottom plate 1 and the bottom plate 2 11 play the role of supporting the sliding groove 13.

[0042] Furthermore, when the motor 203 is started, the output end of the motor 203 drives the roller 204 to rotate. Since the left side of the roller 204 is fixedly connected to the extension plate 205, and the left side of the extension plate 205 is fixedly connected to the fan 206, when the roller 204 rotates, it will drive the extension plate 205 and the fan 206 to move together. During the welding process of the forklift mast, the roller 204 is driven to rotate by the motor 203, so that the fan 206 can move within the range limited by the movable groove 201, thereby expanding the range of blowing air and helping to reduce the temperature of the welding part.
