Therefore, a column assembly welding fixture is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a welding fixture for column components, which has the advantage of strong adaptability. It solves the problem that existing welding fixtures are not convenient for adjusting the position of short columns according to welding requirements when welding long and short columns, resulting in poor welding adaptability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding fixture for a column assembly, including a base plate, wherein the base plate is provided with a column welding auxiliary positioning structure;

[0007] The column welding auxiliary positioning structure includes two side plates fixedly installed on the upper surface of the base plate. A cylinder is fixedly installed on the surface of the side plate, and a fixing seat is fixedly installed at the output end of the cylinder. A groove is formed on the surface of the fixing seat, and a fixing component for fixing the end of the column is provided in the groove. A short column fixing frame is slidably installed on the surface of the base plate. A short column clamping component is provided inside the short column fixing frame, and a locking component is provided between the short column fixing frame and the base plate.

[0008] Furthermore, the number of cylinders is two, and the two cylinders are distributed on opposite sides of the two side plates.

[0009] Furthermore, the number of the fixed seats is the same as the number of cylinders, the two fixed seats are on the same horizontal line, and the fixed seats are in sliding contact with the base plate.

[0010] Furthermore, the fixing assembly includes a pad block fixedly installed inside the groove and two first electric telescopic rods, the output end of which is fixedly installed with an inclined block.

[0011] Furthermore, the pad is located between the two first electric telescopic rods, and an arc-shaped groove is formed on the upper surface of the pad, with the inclined surfaces of the two inclined blocks corresponding to each other.

[0012] Furthermore, the short column clamping assembly includes two second electric telescopic rods fixedly installed on opposite sides of the inside of the short column fixing frame. A semi-enclosed clamping plate is fixedly installed at the output end of the second electric telescopic rod, and the inner width of the semi-enclosed clamping plate gradually decreases from the opening towards the second electric telescopic rod.

[0013] Furthermore, the locking assembly includes a connecting plate fixedly installed on the lower surface of the short column fixing frame. A mounting cylinder penetrating the connecting plate is fixedly installed on the surface of the connecting plate. A plurality of damping rods are fixedly installed inside the mounting cylinder.

A rack and pinion groove and two T-shaped sliding grooves are formed on one side surface of the base plate. Two T-shaped sliders that are engaged with the T-shaped sliding grooves are fixedly installed on the surface of the connecting plate.

[0014] Furthermore, a tie rod extending through to the outside of the mounting cylinder is fixedly installed on the surface of the connecting block away from the rack and pinion plate, and both the mounting cylinder and the connecting block are square in shape.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. The welding fixture for this column assembly allows for the movement and fixation of the short column fixing frame via a locking component. When the position of the short column needs to be adjusted, the connecting block and rack and pinion plate can be moved by pulling the pull rod, releasing the lock with the rack and pinion slot, allowing the short column fixing frame to slide along the T-shaped slide groove. After adjusting to the appropriate position, the pull rod is released, and the damping rod pushes the connecting block and rack and pinion plate back into the rack and pinion slot, achieving locking. This makes the position adjustment operation of the short column fixing frame and the short column simple and flexible.

[0017] 2. The welding fixture for this column assembly uses two second electric telescopic rods and a semi-enclosed clamping plate to clamp the short column. The design of the semi-enclosed clamping plate with a gradually decreasing inner width can better fit the shape of the short column, provide more reliable clamping force, and ensure that the short column remains stable during the welding process.

[0018] 3. The welding fixture for the column assembly, by opening a groove on the surface of the fixed seat and setting a fixing component including a pad, two first electric telescopic rods and an inclined block in the groove, can fix the end of the column, which enhances the firmness and stability of the column fixation, prevents the column from moving during the welding process, and helps to improve the accuracy and quality of welding.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 3In this embodiment, a column assembly welding fixture includes a base plate 1. The base plate 1 is provided with a column welding auxiliary positioning structure. The column welding auxiliary positioning structure includes two side plates 2 fixedly installed on the upper surface of the base plate 1. A cylinder 3 is fixedly installed on the surface of the side plate 2. A fixing seat 4 is fixedly installed at the output end of the cylinder 3. A groove 5 is opened on the surface of the fixing seat 4. A fixing component for fixing the end of the column is provided in the groove 5. A short column fixing frame 6 is slidably installed on the surface of the base plate 1. A short column clamping component is provided inside the short column fixing frame 6. A locking component is provided between the short column fixing frame 6 and the base plate 1.

[0025] It should be noted that there are two cylinders 3, which are distributed on opposite sides of the two side plates 2. The number of fixing seats 4 is the same as the number of cylinders 3. The two fixing seats 4 are on the same horizontal line and slide in contact with the base plate 1.

[0026] The fixing component includes a pad 7 fixedly installed inside the groove 5 and two first electric telescopic rods 8. The output end of the first electric telescopic rod 8 is fixedly installed with a bevel block 9. The fixing component facilitates the fixing of both ends of the column.

[0027] Among them, the pad 7 is located between the two first electric telescopic rods 8, and the upper surface of the pad 7 is provided with an arc groove 10, and the inclined surfaces of the two inclined blocks 9 correspond to each other.

[0028] The short column clamping assembly includes two second electric telescopic rods 11 fixedly installed on opposite sides of the inside of the short column fixing frame 6. A semi-enclosed clamping plate 12 is fixedly installed at the output end of the second electric telescopic rod 11. The inner width of the semi-enclosed clamping plate 12 gradually decreases from the opening towards the second electric telescopic rod 11.

[0029] The locking assembly includes a connecting plate 13 fixedly installed on the lower surface of the short column fixing frame 6. A mounting cylinder 14 is fixedly installed on the surface of the connecting plate 13, penetrating the connecting plate 13. A plurality of damping rods 15 are fixedly installed inside the mounting cylinder 14. A connecting block 16 is fixedly installed at the output end of the damping rod 15. A rack and pinion plate 17 is fixedly installed on one side surface of the connecting block 16. A rack and pinion groove 18 and two T-shaped slide grooves 19 are opened on one side surface of the base plate 1. Two T-shaped sliders 20 are fixedly installed on the surface of the connecting plate 13 and engage with the T-shaped slide grooves 19, which facilitates the movement of the short column fixing frame 6 on the base plate 1 and also facilitates locking the position of the short column fixing frame 6.

[0030] Among them, a tie rod 21 is fixedly installed on the surface of the connecting block 16 away from the rack and pinion plate 17, extending through to the outside of the mounting cylinder 14. Both the mounting cylinder 14 and the connecting block 16 are square in shape.

[0031] It should be noted that in this embodiment, the multiple first electric telescopic rods 8 and the second electric telescopic rods 11 are precisely controlled by a programmable logic controller, and the synchronous movement of the multiple first electric telescopic rods 8 and the second electric telescopic rods 11 is achieved through programming.

[0032] The working principle of the above embodiments is as follows:

[0033] When positioning the long column is required, cylinder 3 is activated, and its output end extends, pushing the fixing seat 4 to slide on the base plate 1. Both fixing seats 4 move simultaneously towards the center, close to both ends of the long column, placing the ends of the long column in the groove 5 and contacting the arc-shaped groove 10 on the pad 7. Once the fixing seat 4 has moved to the appropriate position, the two first electric telescopic rods 8 are activated, extending their output ends and driving the inclined blocks 9 towards the ends of the long column, causing the inclined surfaces of the two inclined blocks 9 to gradually approach and press against the surface of the long column, thus fixing the long column. The short column is then placed between the two semi-enclosed clamping plates 12, and the first... The two electric telescopic rods 11 push the semi-enclosed clamping plate 12 towards the short column. The special shape of the inner side of the semi-enclosed clamping plate 12 can better fit the short column, thus firmly clamping it. When the position of the short column needs to be adjusted, the operator manually pulls the pull rod 21. The pull rod 21 drives the connecting block 16 to move inside the mounting cylinder 14, while simultaneously compressing the damping rod 15. The movement of the connecting block 16 will cause the rack and pinion plate 17 to disengage from the rack and pinion groove 18 on the base plate 1. At this time, the lock between the short column fixing bracket 6 and the base plate 1 is released, and the short column fixing bracket 6 can slide along the T-shaped slide groove 19 on the base plate 1, thereby moving the clamped short column. When the short column moves to the appropriate position, the pull rod 21 is released, the damping rod 15 returns to its original state, and the connecting block 16 and the rack and pinion plate 17 are pushed back into the rack and pinion groove 18, relocking the short column fixing bracket 6 onto the base plate 1, thus realizing the adjustment and fixation of the short column position.
