Description
Technical Field
[0001] The utility model relates to the technical field of welding tooling, in particular to a laser welding tooling for arc horizontal bends. Background Technique
[0002] As Figure 1 shown in the arc horizontal bend structure, it is a channel formed by arc-shaped plate components on the inner and outer sides and two cross beams at the bottom through laser welding. After docking with the straight cable trays at both ends, it can smoothly turn the cable by 90 degrees to meet the cable laying requirements.
[0003] The welding precision of the arc-shaped plate component and the end of the cross beam will directly affect the form and position tolerance of the arc horizontal bend. Therefore, in the prior art, tooling is used to fix the positions of the arc-shaped plate components on both sides and the two cross beams before welding to improve the welding precision. However, the fixing form is single. For similar products with the same radian and different distances between the arc-shaped plate components on both sides, multiple toolings need to be reserved, occupying the storage space in the factory area and being not flexible enough to use.
[0004] In order to solve the above problems, a laser welding tooling for arc horizontal bends is proposed. Content of the Utility Model
[0005] The purpose of the utility model is to provide a laser welding tooling for arc horizontal bends, which has three fixing forms and can clamp and position similar products, thus solving the problems proposed in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solutions:
[0007] The laser welding tooling for arc horizontal bends includes a fan-shaped box. An arc plate clamping member is arranged on the upper side of the fan-shaped box, and three arc plate clamping members are evenly distributed along the arc side direction of the fan-shaped box; two pairs of straight plates are fixedly installed on the upper side of the fan-shaped box, and the symmetry axes of each pair of straight plates are arranged along the radial direction of the fan-shaped box. Each pair of straight plates is located between two adjacent arc plate clamping members. A transmission component for connecting the arc plate clamping members and a driving component for driving the transmission component are arranged inside the fan-shaped box.
[0008] Specifically, the arc plate clamping member includes a first arc plate and a second arc plate. The first arc plate is fixedly assembled with the fan-shaped box, and the second arc plate is slidably assembled with the fan-shaped box. The first arc plates are arranged along the radial direction of the fan-shaped box. There are three first arc plates close to the arc side of the fan-shaped box and one first arc plate far from the arc side of the fan-shaped box. Second arc plates are arranged on the same side of each first arc plate. Guide grooves are opened at the top of the fan-shaped box, and a pair of guide grooves are arranged below each second arc plate.
[0009] Specifically, the transmission assembly includes a transmission frame, a spring and a guide cylinder. A pair of guide cylinders are fixedly installed at the inner bottom of the sector box and below the arc plate clamping member. Each pair of guide cylinders slidably mounts a transmission frame. A plurality of pairs of connecting columns are evenly and fixedly installed on the upper side of the transmission frame. The upper end of each pair of connecting columns passes through the guide groove and is fixedly assembled with a second arc plate. The transmission frame is sleeved with a spring, and the spring is located between the arc side of the sector box and the guide cylinder. One end of the spring abuts against the guide cylinder, and the other end is fixedly assembled with the transmission frame through a positioning ring.
[0010] Specifically, the driving assembly includes a worm, a winding roller and a worm gear.

[0012] The beneficial effects of the present utility model are as follows:
[0013] By controlling the driving assembly, all the second arc plates can be simultaneously controlled through the transmission assembly, so that the second arc plates and the first arc plates can form an opening and closing action to clamp and position the arc plate components on both the inner and outer sides. In addition, the two pairs of straight plates can position crossbeams of different lengths, and one tooling can meet the welding and positioning requirements of three similar products; compared with the existing tooling, the spare quantity and the occupied storage space are smaller, and the use is more flexible.

Detailed Embodiment
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Embodiment:
[0021] Please refer to Figure 2 、 Figure 3 and Figure 4 The present utility model provides a laser welding tooling for an arc horizontal bend, including a sector box 1, which is formed by buckling a sector box body and a sector box cover. An arc plate clamping member 3 is arranged on the upper side of the sector box 1. Three arc plate clamping members 3 are evenly distributed along the arc side direction of the sector box 1. The arc plate clamping member 3 is used to clamp and fix two arc plate components of the arc horizontal bend. The distribution mode of the three arc plate clamping members 3 can clamp the two ends and the middle of the arc plate component respectively, which is beneficial to maintaining the radian of the arc plate component.
[0022] Two pairs of straight plates 4 are fixedly installed on the upper side of the sector box 1. The symmetry axes of each pair of straight plates 4 are arranged along the radial direction of the sector box 1. Each pair of straight plates 4 is located between two adjacent arc plate clamping members 3. The two pairs of straight plates 4 are used to place two cross beams of the arc horizontal bend; a transmission component 5 for connecting the arc plate clamping members 3 and a driving component 7 for driving the transmission component 5 are arranged inside the sector box 1. By operating the driving component 7, the opening and closing actions of all arc plate clamping members 3 can be controlled simultaneously through the transmission component 5, which is convenient for placing and clamping and fixing the arc plate component.
[0023] Specifically, the arc plate clamping member 3 includes a first arc plate 31 and a second arc plate 32. The first arc plate 31 is fixedly assembled with the sector box 1, and the second arc plate 32 is slidably assembled with the sector box 1. The first arc plate 31 is distributed along the radial direction of the sector box 1. There are three first arc plates 31 close to the arc side of the sector box 1 and one first arc plate 31 far from the arc side of the sector box 1. The second arc plate 32 is arranged on the same side of each first arc plate 31. A guide groove 2 is opened at the top of the sector box 1. A pair of guide grooves 2 are arranged below each second arc plate 32; the first arc plate 31 and the second arc plate 32 far from the arc side of the sector box 1 are used to clamp the inner arc plate component at the same position, while the first arc plate 31 and the second arc plate 32 close to the arc side of the sector box 1 form three distance positions for clamping the outer arc plate component, and three arc horizontal bends with different widths can be made.
[0024] Specifically, as Figure 4As shown in the figure, the transmission assembly 5 includes a transmission frame 51, a spring 53, and a guide cylinder 54. A pair of guide cylinders 54 are fixedly installed at the inner bottom of the sector box 1 and below the arc plate clamping member 3. Each pair of guide cylinders 54 slidably mounts a transmission frame 51. A plurality of pairs of connecting columns 52 are evenly fixedly installed on the upper side of the transmission frame 51. The upper ends of each pair of connecting columns 52 pass through the guide groove 2 and are fixedly assembled with a second arc plate 32. A spring 53 is sleeved on the transmission frame 51, and the spring 53 is located between the arc side of the sector box 1 and the guide cylinder 54. One end of the spring 53 abuts against the guide cylinder 54, and the other end is fixedly assembled with the transmission frame 51 through a positioning ring. The spring 53 can apply a force to move the transmission frame 51 closer to the arc side of the sector box 1 through the positioning ring, so that the second arc plate 32 on the connecting column 52 has a force to move towards the first arc plate 31, clamping the arc plate component located between the second arc plate 32 and the first arc plate 31.
[0025] Specifically, as Figure 3 shown, the drive assembly 7 includes a worm 71, a winding roller 72, and a worm gear 73. The inner bottom of the sector box 1 is rotatably installed with a worm 71 through a pair of bearing seats, and a winding roller 72 and a worm gear 73 are also rotatably installed through a vertical rod. The winding roller 72 is fixedly installed on the upper side of the worm gear 73. The worm gear 73 is meshed and assembled with the worm 71. The number of vertical rods is three and they are located between the worm 71 and the transmission frame 51. One end of a steel cable 74 is fixedly installed on the winding roller 72, and the other end of the steel cable 74 is fixedly assembled with the transmission frame 51 respectively. The rotating worm 71 can rotate the worm gear 73 and the winding roller 72 thereon at the same time, so as to wind or release the steel cable 74 at the same time, completing the operation of pulling or putting back the transmission frame 51. Due to the meshing of the worm 71 and the worm gear 73, there is also a reverse braking ability, so that the winding roller 72 that rotates during winding will not reverse and reset by itself.
[0026] Furthermore, one end of the worm 71 passes through the sector box 1 and is fixedly installed with a handwheel 6. The setting of the handwheel 6 is beneficial to rotating the worm 71.
[0027] The working principle of this embodiment:
[0028] During use, first rotate the handwheel 6 forward. After transmission, the rotating winding roller 72 winds the steel cable 74, pulls the transmission frame 51 along the guide cylinder 54 in the direction away from the arc side of the sector box 1, and compresses the spring 53 to store energy. At this time, the second arc plate 32 moves away from the first arc plate 31 and is positioned, facilitating placing the arc plate components on the inner and outer sides at the matching positions and placing the cross beam between the two pairs of straight plates 4.
[0029] Rotate the handwheel 6 in the reverse direction. The restoration of the spring 53 causes the transmission frame 51 to reset along the guide cylinder 54, and at the same time drives the second arc plate 32 to move closer to the first arc plate 31, clamping the inner arc plate component. At the same time, the two ends of the cross beam respectively abut against the arc plate components on both sides.
[0030] Each part of the arc horizontal bend is accurately positioned, formed by laser welding, with high finished product form and position accuracy and flexible use.
[0031] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
