Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an auxiliary welding tool for the reel flange to solve the problem that the existing reel flange will destroy the overall structure of the reel during welding, which will easily cause deformation of the rope groove and damage the reel. Under the support of the outer support, it is easy to produce axial jump when rotating, which affects the stability of the drum support

Embodiment 1

[0052] like Figure 1-3As shown, a reel sidewall auxiliary welding tool includes a bottom plate 106, a reel clamping fixture 3, and a sidewall fixture 4. The upper side of the bottom plate 106 is provided with a number of first guide grooves 107, and one end of the bottom plate 106 is provided with a The fixed seat 110, the other end of the bottom plate 106 is provided with a sliding seat 111 that is slidably installed inside the first guide groove 107, and one end of the bottom plate 106 close to the sliding seat 111 is provided with a support plate 109, the support plate 109 is threadedly connected with an adjusting screw 112 , one end of the adjusting screw 112 is movably connected with the sliding seat 111, and the other end of the adjusting screw 112 is provided with a hand wheel 113; the adjusting screw 112 is used to adjust the distance between the fixed seat 110 and the sliding seat 111, so as to facilitate the reels of different lengths Supporting use; one side of the...

Embodiment 2

[0059] The difference from Example 1 is that as Figure 11 As shown, in this embodiment, the reel pressing fixture 3 includes a plurality of L-shaped fixing brackets 313 fixedly installed on the support arm 2 and a cone 309 slidably installed on the support arm 2. One end is provided with a first bushing 314, a third support rod 311 is slidably installed inside the first bushing 314, the upper end of the third support rod 311 is rotatably connected with a support wheel 312, and the cone 309 is provided with several The guide rail 310 and the lower end of the third support rod 311 are connected with a guide wheel, and the guide wheel is slidably installed inside the guide rail 310 . When the reel 7 is pressed tightly, the first screw sleeve 308 is rotated to move the cone 309 to the middle of the reel 7. When the cone 309 moves, the guide wheel at the lower end of the third support rod 311 slides on the outer wall of the cone 309 to drive the first The three support rods 311 m...

Embodiment 3

[0063] The difference from Example 1 is that as Figure 12-14As shown, in this embodiment, the beating mechanism includes a second driving bevel gear 612 fixedly mounted on the connecting sleeve 604, and two sets of second shaft sleeves 614 are connected to the inner side of the support frame 601. A drive shaft 615 is rotatably connected to the second bushing 614. The lower end of the drive shaft 615 is provided with a second driven bevel gear 613 meshing with the second drive bevel gear 612, and the upper end of the drive shaft 615 is provided with a plurality of drive teeth 617. The upper second shaft sleeve 614 is provided with a beating shaft 616, and there are several guide grooves (not shown in the figure) on the side wall of the jumping shaft 616. A guide bar (not shown in the figure), so that the jumping shaft 616 can only slide up and down in the second sleeve 614, but cannot rotate in the second sleeve 614; the lower end of the jumping shaft 616 is provided with a pl...

Abstract

The invention discloses an auxiliary welding tool for the sidewall of a reel, which comprises a bottom plate, a reel top-tightening fixture and a sidewall fixture. One end of the bottom plate is provided with a fixing seat, and the other end of the bottom plate is provided with a sliding seat for sliding installation and inside a first guide groove. ;One side of the fixed seat and the sliding seat are rotatably connected with a support arm, the reel clamping fixture is arranged inside the reel, and the reel clamping fixture is a retractable structure; the sidewall clamp includes a chuck body, and the inside of the chuck body is There is a large bevel gear, one side of the large bevel gear is provided with a spiral groove, one side of the spiral groove is screwed with a number of claws, the end of the claws is provided with steps, and the claws are slidably connected with the chuck body; One side of the gear is meshed with several small bevel gears. The reel clamping fixture of the invention pushes the inner wall of the reel, avoids damage to the rope groove of the reel when the reel is supported, and avoids the axial jump when the reel is rotated during the welding process, ensuring that the reel is The stability of the support ensures the welding quality of the flange and the drum.

Description

technical field [0001] The invention belongs to the technical field of reel welding, and in particular relates to an auxiliary welding tool for the sidewall of a reel. Background technique [0002] As a key accessory of hoisting equipment, the drum is widely used in high-end engineering equipment such as crawler, rotary drilling rig, port crane, large tower crane, etc. The performance of the drum determines the height and tonnage of the hoisting equipment, and even seriously affects the The service life of the wire rope. The reel generally includes a cylinder with a spiral rope groove and ribs (flanges) welded at both ends of the cylinder. When the ribs are welded to the cylinder, it is not only necessary to ensure the parallelism of the ribs on both sides, but also the ribs. Perpendicularity to the barrel. [0003] The Chinese utility model patent publication number CN210209265U discloses an electric hoist reel shell welding fixture, and specifically discloses: the fixtur...
