Description

Technical Field

[0001] This utility model relates to the field of angle iron flange processing technology, specifically a magnetic auxiliary tooling for positioning angle iron flanges. Background Technology

[0002] Angle iron flanges are not like traditional round flanges. Instead, they are components welded from angle steel and right-angle flanges. They are commonly used in ventilation systems to connect different sections of ventilation ducts. The angle steel at the edge has a ring of holes inside for connecting bolts and nuts to lock it in place.

[0003] When cutting or stamping, the angle iron and flanges of this component inevitably have burrs at the edges that need to be cleaned. In order to prevent the angle iron flange from shaking, auxiliary tooling is needed to use magnetic force to attract it. However, the tooling equipment used in the past often assembled the structure in advance according to the volume of the angle iron flange, and the spacing of the structure could not be adjusted in time, which was quite inconvenient to use.

[0004] Now, a novel magnetic auxiliary tooling for positioning angle iron flanges is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic auxiliary tooling for positioning angle iron flanges, so as to solve the problem of inconvenient adjustment of structural spacing mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a magnetic auxiliary tooling for positioning angle iron flanges, comprising a base plate, a groove horizontally provided at the front end of the center of the base plate, a handle movably connected to the lower left corner of the front surface of the base plate, a slot provided inside the lower left corner of the base plate, a worm gear movably connected between the upper left and right sides of the slot, a worm gear movably connected between the lower front and rear sides of the slot, a transverse groove provided between the lower left and right sides of the base plate, a lead screw movably connected between the left and right sides of the transverse groove, threaded sleeves threadedly connected to both sides of the lead screw, a support rod fitting between the front end of the threaded sleeve and the base plate, an angle iron flange body placed between the front of the two support rods, and holes provided around the edges of the angle iron flange body.

[0007] As a further technical solution of this utility model, the rear of the swivel handle is fixedly connected to the worm gear, and the left side of the lead screw is fixedly connected to the worm wheel.

[0008] As a further technical solution of this utility model, brackets are fixed on both sides of the front end of the threaded sleeve, and a retaining sleeve is movably connected between the upper and lower parts inside the bracket. A bolt is threadedly connected to the top of the outer side of the bracket. A retaining groove is provided on both sides below the front end of the support rod. Two sets of connecting pieces are fixed on the outer side of the support rod. A limiting groove is provided between the left and right sides of the top end inside the groove, and guide plates are movably connected to both sides inside the limiting groove. Screws are threadedly connected between the guide plates and the connecting pieces.

[0009] As a further technical solution of this utility model, the sleeve is embedded in the slot, the bolt two abuts against the sleeve in the bracket, and the top of the guide plate is embedded in the limiting groove.

[0010] As a further technical solution of this utility model, a slide rail is provided between the upper and lower parts inside the front end of the support rod, and a toothed rack is fixed longitudinally on the right side inside the slide rail. Two sets of sliders are movably connected in the slide rail, and a positioning block is fixed at the front end of the slider. A sleeve is fixed on the outer side of the positioning block. An insert rod is movably connected between the two sleeves. A magnet is fixed inside the front end of the positioning block. Assembly pieces are fixed at the top and bottom of the slider, and a bolt is threaded into the assembly piece. Ball bearings are movably embedded at the upper and lower parts on the left side of the slider. Gears are movably connected at the upper and lower parts on the right side of the slider. A screw hole is provided between the upper and lower parts at the rear of the slide rail.

[0011] As a further technical solution of this utility model, the ball is in contact with the inner wall of the slide, the right side of the gear meshes with the gear rack, and the bolt is embedded between the screw hole and the assembly piece.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the magnetic auxiliary tooling for positioning angle iron flanges not only realizes the adjustment of the spacing of the support structure and facilitates the disassembly and installation of various components, but also achieves the stability of maintaining the magnetic adsorption. (1) By providing a transverse groove between the left and right sides inside the base plate, the support rods on both sides are installed on the outside of the threaded sleeve. Then, the handle in the lower left corner is rotated to mesh with the worm gear by rotating the handle, and then the screw is guided to rotate in the transverse groove. The spacing of the symmetrical support rods is adjusted by self-locking so that the angle iron flange body is attached between the four sets of positioning blocks. It is fixed by the magnet in the positioning block, and the two adjacent positioning blocks are balanced by the sleeve and the insertion rod. (2) By moving the sleeve between the upper and lower parts inside the bracket, the bottom of the support rod is attached to the surface of the threaded sleeve on both sides. After aligning with the slots on the lower sides, the sleeve is moved inside the bracket until it is embedded in the slot. Tighten the bolts to prevent the sleeve from loosening. Then, the connecting piece on the side of the support rod is installed on the guide plate with screws, so that the support rod moves with the threaded sleeve, and the guide plate slides left and right along the groove and the limiting groove, ensuring smooth movement of the tooling parts and facilitating disassembly and installation. (3) Two sets of sliders are connected in the slide. Each support rod has two sets of sliders in the slide. Under the lubrication of the ball on the left and the meshing transmission of the gear and tooth row on the right, the positioning block moves along the slide. After aligning with the screw hole, the bolt is screwed in to lock the position so that the magnet can be attracted and fixed to the holes on both sides of the angle iron flange body. The attraction position is variable and can be adjusted according to the specifications of the angle iron flange body. Attached Figure Description
