Abstract
Description
Technical Field
[0001] This utility model belongs to the field of welding tooling technology, specifically relating to a welding positioning tooling for mop boxes. Background Technology
[0002] The mop box on a bus is typically welded from a U-shaped roller body and a reinforcing plate. Currently, welding these mop boxes usually doesn't use positioning fixtures or only clamps a few points. The unclamped areas are free during welding, requiring constant manual correction. Due to variations in the manufacturing of individual parts and the lack of fixtures for positioning and clamping, welding deformation and surface protrusions are common problems, resulting in inconsistent weld shapes. When weld deviations are too large, the weld needs to be cut open and re-welded. Given the current problems of poor overall weld consistency, low production efficiency, high labor intensity, and high production costs in mop box welding, it is necessary to design a positioning fixture for mop box welding to improve welding quality.

Detailed Implementation
[0023] See also Figure 1-6 This embodiment provides a welding positioning fixture for a mop box, including a base 1 and a transverse positioning part 2, a longitudinal positioning part 3, a longitudinal clamping part 4, and a linear drive module 5 disposed on the base 1. The positioning surfaces of the transverse positioning part 2 and the longitudinal positioning part 3 are both perpendicular to the surface of the base 1. The linear drive module 5 is connected to the longitudinal clamping part 4 to drive the longitudinal clamping part 4 to move relative to the longitudinal positioning part 3. A limiting part extending along the moving direction of the longitudinal clamping part 4 is detachably connected to one side of the transverse positioning part 2. The limiting part limits the distance between the longitudinal clamping part 4 and the longitudinal positioning part 3 during welding.
[0024] In this embodiment, the linear drive module 5 includes a ball screw 51 and a sliding guide structure. One end of the ball screw 51 is connected to a handwheel 52 for rotation, and the nut of the ball screw 51 is fixedly connected to the bottom of the longitudinal clamping part 4. The sliding guide structure includes a linear guide 53 extending along the moving direction of the longitudinal clamping part 4 and a slider 54 that slides in cooperation with the linear guide 53. The slider 54 is fixedly connected to the bottom of the longitudinal clamping part 4. By rotating the ball screw 51 in both forward and reverse directions, the longitudinal clamping part 4 is driven to move forward and backward, clamping and releasing the U-shaped roller box 71. When the handwheel 52 is rotated so that the longitudinal clamping part 4 abuts against the limiting part 6, the longitudinal clamping part 4 is in position. During the welding process, the U-shaped roller box 71 is always in a clamped state for welding, resulting in good product welding consistency and stable production. The combination design of the linear guide 53 and the ball screw 51 provides high tooling guidance accuracy and good cooperation of the longitudinal clamping part 4.
[0025] In this embodiment, two negative pressure suction cups 11 are provided on the surface of the base 1 where the welding parts are laid, and the negative pressure suction cups 11 do not extend beyond the surface of the base 1. The two negative pressure suction cups 11 are connected to the bottom vacuum suction cup system 13 through air pipe one 15 and air pipe two 17 respectively. Then the bottom vacuum suction cup system 13 is connected to the compressed air in the workshop. The negative pressure suction cups 11 better fix the L-shaped box reinforcement plate 73 by adsorption, preventing the L-shaped box reinforcement plate 73 from running along its own length direction during welding.
[0026] In this embodiment, the limiting part 6 includes a fixing part 61 fixedly connected to the transverse positioning part 2, an abutting part 63 threadedly connected to the fixing part 61, and a plurality of gaskets 66 placed between the fixing part 61 and the abutting part 63. The abutting part 63 abuts against the longitudinal clamping part 4 and limits the distance between the longitudinal clamping part 4 and the longitudinal positioning part 3 during welding. Therefore, during welding operations, only the gaskets 66 need to be added or removed to quickly adjust the limiting distance between the longitudinal clamping part 4 and the longitudinal positioning part 3. The limiting distance between the longitudinal clamping part 4 and the longitudinal positioning part 3 determines the size of the mop box body to be welded. Therefore, the limiting part 6 can be used to weld mop box bodies of different widths.
[0027] In this embodiment, the base 1 has a hollow structure. The positioning surfaces of the transverse positioning part 2, the longitudinal positioning part 3, and the surface of the base 1 used for placing the welded parts intersect in pairs to form an L-shape. The linear drive module 5 is installed inside the hollow structure of the base 1. The bottom of the longitudinal clamping part 4 is fixedly connected to the output end of the linear drive module 5, and the clamping surface of the longitudinal clamping part 4 is parallel to the positioning surface of the longitudinal positioning part 3. The transverse positioning part 2, the longitudinal positioning part 3, and the base 1 intersect in pairs to form an L-shape, allowing workers to directly place parts into the L-shaped backrest of the fixture during operation, achieving rapid part positioning and improving production efficiency. The transverse positioning part 2, the longitudinal positioning part 3, and the longitudinal clamping part 4 are used to perform a full clamping welding operation on the U-shaped roller box 71. The welding process does not require manual correction of the welding, improving welding efficiency and welding accuracy. The longitudinal positioning part 3 includes a longitudinal positioning plate 31 perpendicularly connected to the surface of the base 1 and a plurality of positioning support plates 33 perpendicularly connected to the longitudinal positioning plate 31. The positioning support plates 33 are also perpendicularly connected to the surface of the base 1, and the positioning support plates 33 enhance the structural strength of the longitudinal positioning part 3. The longitudinal clamping part 4 includes a longitudinal clamping plate 41 perpendicular to the surface of the base 1, a clamping connecting plate 43 perpendicularly connected to the longitudinal clamping plate 41 and coplanar or parallel to the surface of the base 1, and a plurality of clamping support plates 45 perpendicularly connected to the longitudinal clamping plate 41 and the clamping connecting plate 43 respectively. The linear drive module 5 is fixedly connected to the bottom of the clamping connecting plate 43, and the clamping support plates 45 enhance the structural strength of the longitudinal clamping part 4.
[0028] In other embodiments, the limiting part can also be designed as a plate-like structure with an oblong hole. The limiting part is threadedly connected to the transverse positioning part 2 through the oblong hole, and the oblong hole extends along the moving direction of the longitudinal clamping part 4; or, it can be designed as a bolt threadedly connected to the transverse positioning part 2, with the bolt's axis along the moving direction of the longitudinal clamping part 4, and the bolt's nut located on the side where the longitudinal clamping part 4 is located to abut against the longitudinal clamping part 4. As long as the limiting distance between the longitudinal clamping part 4 and the longitudinal positioning part 3 can be quickly adjusted, it is acceptable.
