Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, and in particular to an auxiliary welding fixture for attaching workpieces to platform terminal equipment. Background Technology

[0002] In critical areas such as railway stations and rail transit stations, it is usually necessary to install mounting devices above the platform to suspend terminal equipment such as cameras, clocks, and displays. Furthermore, since most current platforms are constructed of poured concrete and are designed with roof beams to increase the load-bearing capacity of the canopy, the mounting devices are typically fixed to the roof beams to avoid damaging the canopy structure during installation.

[0003] Existing common mounting components include a boom, with terminal equipment such as cameras, clocks, and displays fixedly mounted at the lower end of the boom. The upper end of the boom is then fixedly connected to the lower surface of the platform canopy's roof beam via a welded flange mounting plate. Since the lower surface of the roof beam is often sloped, to ensure the verticality of the terminal equipment mounted at the lower end of the boom, the angle of the flange mounting plate must be consistent with the angle of the lower surface of the roof beam—meaning the flange mounting plate and the end of the boom are welded at a certain angle.

[0004] However, currently, when welding between the flange mounting plate and the end of the boom, the lack of suitable auxiliary welding tools often leads to errors in the included angle between the flange mounting plate and the end of the boom, thus affecting the verticality of the terminal equipment after installation. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary welding fixture for attaching workpieces to platform terminal equipment. It can realize the pre-welding butt joint between the flange mounting plate and the end of the hanger rod, and adjust the included angle between the two to avoid errors in the included angle, thereby ensuring the verticality of the terminal equipment installation.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is: an auxiliary welding fixture for hanging workpieces on platform terminal equipment, including a base, a platform frame for horizontally fixing the hanging rod on the top of the base, and a rectangular support plate with its lower edge hinged to the base on one side of the platform frame. The lower edge of the rectangular support plate is horizontally set and its extension direction is perpendicular to the extension direction of the hanging rod.

[0007] The rectangular support plate has an adjustable support rod horizontally provided on the plate surface near the hanger to support the lower edge of the flange mounting plate. An angle adjustment component for adjusting the hinge angle of the rectangular support plate is provided between the lower plate surface of the rectangular support plate and the platform frame. An angle indicator component is also provided on the side edge of the rectangular support plate.

[0008] As a further improvement of this utility model, the top of the platform frame is provided with two parallel limiting ribs that extend in the same direction as the boom. Above the limiting ribs, there is also an elastic band for pressing the boom between the two limiting ribs. The two ends of the elastic band are detachably connected to the two sides of the platform frame.

[0009] As a further improvement of this utility model, the two ends of the elastic band are detachably connected to the door-type clamps on both sides of the platform frame via hooks.

[0010] As a further improvement of this utility model, the rectangular support plates on both sides of the adjustable support rod are provided with strip-shaped openings. The extension direction of the strip-shaped openings is perpendicular to the extension direction of the adjustable support rod, and both sides of the adjustable support rod are adjustablely mounted on the strip-shaped openings by locking bolts.

[0011] As a further improvement of this utility model, the angle adjustment component includes a mounting plate horizontally mounted on the platform frame. An adjustment screw that is clearance-fitted with the mounting plate is provided through the mounting plate, and the end of the adjustment screw near the rectangular support plate is hinged to the rectangular support plate. Anti-loosening nuts are threaded on the adjustment screws on both sides of the mounting plate.

[0012] As a further improvement of this utility model, the angle indicating component includes an indicating arrow extending in the same direction as the side edge of the rectangular support plate. A semi-circular angle ruler is also provided on the base side wall below the indicating arrow, and the origin of the semi-circular angle ruler coincides with one end of the lower edge of the rectangular support plate. The indicating end of the indicating arrow extends to the outside of the semi-circular angle ruler.

[0013] As a further improvement of this utility model, the lower surface of the base is also provided with a plurality of base legs.

[0014] Beneficial effects

[0015] Compared with the prior art, the advantages of the auxiliary welding fixture for attaching workpieces to platform terminal equipment according to this utility model are as follows:

[0016] 1. This tooling, through adjustable support rods, allows flange mounting plates to be stacked and installed on the rectangular support plate near the side closest to the hanger rod. In conjunction with the platform frame used for horizontally fixing the hanger rod, it enables pre-welding butt welding between the flange mounting plate and the end of the hanger rod.

[0017] Because the flange mounting plates are stacked on the rectangular support plate and the lifting rod is horizontally fixed to the top of the platform frame, workers can use the angle adjustment and angle indicator components to accurately adjust the angle between the flange mounting plate and the end of the lifting rod by adjusting the hinge angle of the rectangular support plate. During the adjustment process, the angle between the flange mounting plate and the end of the lifting rod is monitored in real time, thus avoiding errors in the angle and ensuring the verticality of the terminal equipment installation. Furthermore, since the angle between the flange mounting plate and the end of the lifting rod is adjustable, this fixture can also accommodate pre-welding butt joints of workpieces with various angles, giving it good versatility.

[0027] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0028] Example:

[0029] The specific embodiments of this utility model are as follows: Figure 1 , 4 As shown, an auxiliary welding fixture for attaching workpieces to a platform terminal device includes a base 1, and a plurality of base legs 11 are provided on the lower surface of the base 1. In this embodiment, the base 1 adopts a horizontally arranged rectangular frame structure. There are four base legs 11, which are located at the four corners of the lower surface of the base 1. The top of the base 1 is provided with a platform frame 2 for horizontally fixing the hanger rod. Specifically, the lower ends of both sides of the platform frame 2 are fixedly connected to the long sides of the rectangular frame structure of the base 1. At the same time, a rectangular support plate 3 is vertically provided on one side of the platform frame 2, with its lower edge hinged to the short side of one side of the base 1. In this embodiment, the lower edge of the rectangular support plate 3 is horizontally arranged and its extension direction is perpendicular to the extension direction of the hanger rod. Furthermore, an adjustable support rod 32 is horizontally provided on the plate surface of the rectangular support plate 3 near the hanger rod to support the lower edge of the flange mounting plate. In addition, an angle adjustment component for adjusting the hinge angle of the rectangular support plate 3 is provided between the lower plate surface of the rectangular support plate 3 and the platform frame 2, and an angle indicator component is also provided on the side edge of the rectangular support plate 3.

[0030] When using this tooling, first adjust the hinge angle of the rectangular support plate 3 using the angle adjustment component; then, stack the flange mounting plate on the side of the rectangular support plate 3 closest to the platform frame 2; finally, fix the hanger horizontally on the top of the platform frame 2, and make the end of the hanger close to the flange mounting plate contact the flange mounting plate, thereby achieving the pre-welding butt joint between the flange mounting plate and the end of the hanger.

[0031] In this fixture, the flange mounting plates are stacked on the rectangular support plate 37, and the lifting rod is horizontally fixed to the top of the platform frame 2. Therefore, workers can use the angle adjustment and angle indicator components to accurately adjust the angle between the flange mounting plate and the end of the lifting rod by adjusting the hinge angle of the rectangular support plate 3, and obtain the angle in real time during the adjustment process. This fixture avoids errors in the angle between the flange mounting plate and the end of the lifting rod, thus ensuring the verticality of the terminal equipment installation. Furthermore, because the angle between the flange mounting plate and the end of the lifting rod is adjustable, this fixture can also accommodate pre-welding butt joints of workpieces with various angles, giving it good versatility.

[0032] In this tooling, such as Figure 3 As shown, the top of the platform frame 2 has two parallel limiting ribs 21 that extend in the same direction as the hanger. The hanger is placed between the two limiting ribs 21 to prevent it from rolling freely. Simultaneously, an elastic band 22 is provided above the limiting ribs 21 to press the hanger between the two limiting ribs 21, and both ends of the elastic band 22 are detachably connected to both sides of the platform frame 2. The elastic band 22 further secures the hanger, preventing axial rotation and ensuring the hanger's position is fixed during welding.

[0033] In this embodiment, to achieve the installation of the elastic band 22 on the platform frame 2, both ends of the elastic band 22 are detachably connected to the latch-type clamps 23 located on both sides of the platform frame 2 via hooks 221. Since the latch-type clamps 23 are well-known products in the prior art and their structure is generally familiar to those skilled in the art, their specific structure will not be described in detail in this embodiment.

[0034] Meanwhile, regarding the adjustable support rod 32, such as Figure 2 As shown, both sides of the adjustable support rod 32 have rectangular support plates 3 with strip-shaped openings 31. The extension direction of the strip-shaped openings 31 is perpendicular to the extension direction of the adjustable support rod 32, and both sides of the adjustable support rod 32 are adjustablely mounted on the strip-shaped openings 31 by locking bolts 321. By tightening the locking bolts 321, the operator can adjust the position of the adjustable support rod 32 along the extension direction of the strip-shaped openings 31 as needed, thereby adjusting the horizontal height of the adjustable support rod 32.

[0035] Regarding the specific structure of the angle adjustment component: In this embodiment, the angle adjustment component includes a mounting plate 41 horizontally mounted on the platform frame 2. An adjustment screw 4, which is clearance-fitted to the mounting plate 41, is threaded through the mounting plate 41. The end of the adjustment screw 4 closest to the rectangular support plate 3 is hinged to the rectangular support plate 3. Anti-loosening nuts 42 are threaded onto the adjustment screws 4 on both sides of the mounting plate 41. By tightening the anti-loosening nuts 42, the length of the adjustment screw 4 between the mounting plate 41 and the rectangular support plate 3 can be adjusted. Combined with the hinge between the adjustment screw 4 and the rectangular support plate 3, and the clearance fit between the adjustment screw 4 and the mounting plate 41, the angle of the rectangular support plate 3 can be adjusted.

[0036] Meanwhile, regarding the specific structure of the angle indicating component: In this embodiment, the angle indicating component includes an indicating arrow 51 extending in the same direction as the side edge of the rectangular support plate 3. A semi-circular angle ruler 5 is also provided on the side wall of the base 1 below the indicating arrow 51. The origin of the semi-circular angle ruler 5 coincides with one end of the lower edge of the rectangular support plate 3, and the indicating end of the indicating arrow 51 extends to the outside of the semi-circular angle ruler 5. Therefore, through the indication of the semi-circular angle ruler 5 and the indicating arrow 51, the operator can know the hinge angle of the rectangular support plate 3 in real time, and thus know the included angle between the flange mounting plate and the end of the hanger rod.

[0037] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
