Technical Field

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

[0002] In the process of equipment production, a large number of components need to be connected and fixed by welding, and a welding workbench is inevitably required in the welding process.

[0003] There are many structures of welding workbenches in reality, but the height of most welding workbenches is fixed. When workers carry out welding operations, due to the different heights of different people, the welding workbench cannot be adjusted adaptively. Since the welding table cannot be lifted or lowered, workers need to adjust their postures, such as bending over or hunching their backs, to complete the welding operation. When the workload is large, it will bring great physical harm to the health of workers who weld for a long time, as well as potential safety hazards caused by physical fatigue. Summary of the Utility Model

[0004] Based on this, in view of the problem that the height of the welding table cannot be adjusted adaptively, it is necessary to provide a welding auxiliary equipment that can effectively change the height of the welding workbench quickly according to the height requirements of different working populations.

A bottom plate is inserted through the middle of the screw rods. An internal thread sleeve is sleeved on one end of the screw rod passing through the bottom plate. The sleeve is fixedly connected to the bottom of the bottom plate. Synchronous wheels that are in threaded cooperation with each other are sleeved on each screw rod inside the bottom plate, and the synchronous wheels are rotatably connected to the bottom plate. A synchronous belt is connected between each synchronous wheel. A driving wheel for driving the synchronous belt to drive is rotatably connected to the center of the bottom plate.

One end of the first connecting rod is rotatably connected to the first limiting wheel, and one end of the second connecting rod is rotatably connected to the second limiting wheel. The other ends of the first limiting wheel and the second connecting rod are respectively hinged to both sides of the first support. The driving assembly is installed inside the bottom plate, and the driving assembly is used to adjust the distance between the first support and the driving wheel.

[0009] As a preferred solution, the driving assembly is a leveling cylinder. The leveling cylinder is used to adjust the distance between the first support and the driving wheel. The leveling cylinder is fixedly connected to the bottom plate, and the piston rod of the bottom plate is connected to the first support.

[0022] Embodiment 1:

[0023] As Figures 1 - 3 shown,

[0024] An auxiliary device for welding, including a welding workpiece table 1. At least three screw rods 2 are arranged at the bottom of the welding workpiece table 1. A base plate 20 is inserted through the middle of the screw rod 2. One end of the screw rod 2 passing through the base plate 20 is sleeved with an internal thread sleeve 21. The sleeve 21 is fixedly connected to the bottom of the base plate 20. A synchronous pulley 3 that is threadedly matched with each screw rod 2 is sleeved on each screw rod 2 inside the base plate 20, and the synchronous pulley 3 is rotatably connected to the base plate 20. A synchronous belt 4 is connected between each synchronous pulley 3. A driving pulley 19 for driving the synchronous belt 4 to drive is rotatably connected to the center of the base plate 20. A driving motor for driving the driving pulley 19 to rotate inside the base plate 20 is installed on the base plate 20.

[0025] In the above structure, the base plate 20 is supported on the ground through the sleeve 21, and the number of sleeves 21 is equal to the number of screw rods 2, and each sleeve 21 corresponds to a screw rod 2. The purpose of setting at least three screw rods 2 is defined. When three screw rods 2 are set, the three screw rods 2 are distributed in a triangle, and based on the stability of the triangle, the stability of the welding workbench can also be achieved; more screw rods 2 can also be selected to improve the overall stable support. Each screw rod 2 is fixedly connected to the bottom of the welding workbench; in this embodiment, Figure 1 As can be seen, four screw rods 2 are selected and set, and the four screw rods 2 are respectively connected to the four corners of the bottom of the welding workpiece table 1. The screw rod 2 and the welding workpiece table 1 can be connected through a fixing seat. That is, under the condition that the screw rod 2 is threadedly matched with the synchronous pulley 3, the screw rod 2 itself can drive the welding workpiece table 1 to move vertically in the sleeve 21, so as to realize the height change of the welding workpiece table 1 from the ground.

[0026] The working process is as follows: The driving motor uses the base plate 20 as a support and drives the driving pulley 19 inside the base plate 20 to rotate. When the driving pulley 19 rotates, driven by the synchronous belt 4, the four synchronous pulleys 3 rotate synchronously inside the base plate 20. The synchronous pulley 3 is also threadedly matched with the screw rod 2, so as to drive the four screw rods 2 to vertically displace inside the sleeve 21, and then complete the height change of the welding workpiece table 1 from the ground.

[0027] Based on this, in order to ensure that the tension of the synchronous belt 4 can be adjusted to prevent the synchronous belt 4 from slipping with the driving pulley 19, an adjusting device is designed to adjust the tension of the synchronous belt 4.

[0028] Inside the bottom plate 20, there is an adjusting device for adjusting the progress of the synchronous belt 4. The adjusting device includes a first arc-shaped guide rail 5, a first limiting wheel 6, a second limiting wheel 7, a first connecting rod 8, a second connecting rod 9, a first support 10 and a leveling cylinder 11. Among them, the first arc-shaped guide rail 5 is horizontally installed inside the bottom plate 20. The first limiting wheel 6 and the second limiting wheel 7 are slidably connected to the first arc-shaped guide rail 5, and the first limiting wheel 6 and the second limiting wheel 7 are symmetrically distributed on both sides of the first arc-shaped guide rail 5. One end of the first connecting rod 8 is rotatably connected to the first limiting wheel 6, and one end of the second connecting rod 9 is rotatably connected to the second limiting wheel 7. The other end of the first limiting wheel 6 and the other end of the second connecting rod 9 are jointly hinged on both sides of the first support 10. Inside the bottom plate 20, a driving component is installed, and the driving component is used to adjust the distance between the first support 10 and the driving wheel 19.

[0029] Among them, there are two designs for the driving component. The first is driven by a cylinder, and the second is manually rotated and adjusted. The user can select one for assembly according to actual needs.

[0030] The specific details of the first driving component are as follows:

[0031] The driving component is replaced by the leveling cylinder 11. The leveling cylinder 11 pulls the first support 10 to move, increasing the distance between the first support 10 and the driving wheel 19. As a result, the first limiting wheel 6 and the second limiting wheel 7 respectively connected by the first connecting rod 8 and the second connecting rod 9 slide centrally on the first arc-shaped guide rail 5. While the distance between the first limiting wheel 6 and the second limiting wheel 7 becomes shorter, the synchronous belt 4 will be pulled, making the synchronous belt 4 contact the surface of the driving wheel 19 to the greatest extent. Thus, the driving wheel 19 can better drive the synchronous belt 4, and there will be no slipping at the connection between the two, reducing the wear and tear between the two.

[0032] The specific details of the second driving component are as follows:

[0033] The driving component includes a guiding optical axis 12, a first push rod 13, a second push rod 14, a first nut 15, a second nut 16 and a first screw rod 17. Among them, both ends of the guiding optical axis 12 are longitudinally installed inside the bottom plate 20 through fixed seats, and a support is slidably connected to the guiding optical axis 12. Both ends of the first screw rod 17 are horizontally installed inside the bottom plate 20 through bearing seats. The first nut 15 and the second nut 16 are both sleeved on the first screw rod 17 that is in threaded cooperation. One end of the first push rod 13 is hinged to the first support 10, and the other end of the first push rod 13 is hinged to the first nut 15. One end of the second push rod 14 is hinged to the first support 10, and the other end of the second push rod 14 is hinged to the second nut 16.

[0034] During use, simply rotate the first screw 17. The first nut 15 and the second nut 16 move closer to each other. During the approaching process, the first push rod 13 and the second push rod 14 jointly push the first support 10 to approach the first screw 17 on the guiding optical axis 12, thereby pulling the first limiting wheel 6 and the second limiting wheel 7 respectively connected to the first connecting rod 8 and the second connecting rod 9 to perform centering displacement on the first arc-shaped guide rail 5. Thus, while tightening the synchronous belt 4, the contact area between the synchronous belt 4 and the driving wheel 19 is also increased, making it easier to drive the synchronous belt 4 to transmit power.

[0035] A handle 18 for driving the rotation of the first screw 17 is installed on the side of the bottom plate 20. The handle 18 is provided to facilitate manual rotation of the first screw 17, and then complete the adjustment of the tension of the synchronous belt 4.

[0036] The above-described embodiments merely represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
