Description
Technical Field
[0001] This utility model relates to the field of idler roller production technology, and in particular to an idler roller welding fixture. Background Technology
[0002] Idler rollers are key rolling components on belt conveyors. The self-aligning bracket for rotating the rollers typically consists of bottom angle steel, intermediate supports, and outer supports. The materials for the bottom angle steel, intermediate supports, and outer supports are generally angle steel and channel steel. These parts need to be welded together to form a whole. Idler roller welding fixtures are auxiliary tools used to accurately position the various parts of the self-aligning bracket during the manufacturing process of the idler roller bracket. Their core objective is to ensure welding quality, improve production efficiency, and reduce labor intensity. Existing idler roller welding fixtures only focus on limiting the horizontal distance between the intermediate supports and outer supports, without paying attention to whether the grooves on the roller shafts on the intermediate supports and outer supports are on the same plane or coaxial. This can easily cause the rollers to rotate in different directions after installation, affecting the normal operation of the belt conveyor. Utility Model Content

A nut is screwed onto the hexagonal head bolt and is detachably fixed to the middle support positioning plate and the outer support positioning plate.
[0005] Furthermore, the T-shaped telescopic mechanism includes: a T-shaped housing, a micro motor, a first transmission wheel, a transmission belt, a second transmission wheel, a bidirectional internally threaded tube, a screw, and an adjusting rod. The bidirectional internally threaded tube is rotatably installed in the T-shaped housing. The first transmission wheel is fixedly installed on the outer side of the middle of the bidirectional internally threaded tube. The first transmission wheel and the second transmission wheel are connected by a transmission belt. A transmission rod is fixedly connected to the center of the second transmission wheel. The micro motor is fixedly installed at the lower end of the T-shaped housing. The transmission rod passes through the wall of the T-shaped housing and is fixedly connected to the output end of the micro motor. The two ends of the bidirectional internally threaded tube are respectively threaded with screws. Adjusting rods are fixedly connected to the outer sides of the screws. The outer side of the adjusting rod extends out of the T-shaped housing and is fixedly connected to the oblique connecting rod.
[0006] Furthermore, the horizontal adjusting square steel is provided with horizontal adjusting grooves at both ends, and the horizontal rod is provided with a horizontal positioning hole on its inner side.

[0009] Furthermore, a synchronizing rod is fixedly connected between the vertical telescopic rods.
[0010] The beneficial effects of this utility model are as follows: By accurately positioning the bottom angle steel, intermediate support, and outer support of the self-aligning bracket, this utility model ensures that the roller grooves on the intermediate support and outer support are connected so that their axes are in the same plane, avoiding problems such as eccentricity caused by manual positioning. This ensures that after the rollers are installed on the self-aligning bracket, their movement direction is consistent and their rotation is smooth, resulting in low resistance, low noise, and long service life of the belt conveyor during operation; it also provides a stable welding position and improves welding efficiency.

A nut 302 is screwed onto the hexagonal head bolt 301 and is detachably fixed on the middle support positioning plate 30 and the external support positioning plate 40.
[0018] Specifically, the length of the vertical telescopic rod 6 is adjusted, the T-shaped telescopic mechanism 1 is adjusted, the horizontal adjusting square steel 5 and the horizontal rod are fixedly connected, the bottom angle steel positioning plate 60 is placed above the bottom angle steel, the middle support is positioned by the middle support positioning plate 30, and the outer support is positioned by the outer support positioning plate 40. When positioning the middle support and the outer support, the hexagonal head bolt 301 passes through the roller rod slots opened on the middle support and the outer support to limit the front and rear positions of the middle support and the outer support.
[0019] The T-shaped telescopic mechanism 1 includes: a T-shaped housing 10, a micro motor 11, a first transmission wheel 12, a transmission belt 13, a second transmission wheel 14, a bidirectional internally threaded tube 15, a screw 16, and an adjusting rod 17.

[0025] Two positioning blocks 7 are fixedly installed on the top of the T-shaped telescopic mechanism 1, and positioning holes are provided on the positioning blocks 7. When using external tools to fix the fixture, they can cooperate with the positioning holes to prevent shaking.
[0026] Synchronizing rods 61 are fixedly connected between the vertical telescopic rods 6 to ensure that the vertical telescopic rods 6 extend and retract synchronously.
[0027] The working principle of this utility model is as follows: First, adjust the vertical length of the vertical telescopic rod 6, then turn on the micro motor 11 to adjust the horizontal length of the T-shaped telescopic mechanism 1. When adjusting the T-shaped telescopic mechanism 1, the horizontal rod 3 moves horizontally in the horizontal adjusting square steel 5. After the horizontal length of the T-shaped telescopic mechanism 1 is determined, tighten the bolts to fix the horizontal adjusting square steel 5 and the horizontal rod 3. Adjust the position of the oblique adjusting square steel 41 on the side rod 4, and tighten the bolts to fix the oblique adjusting square steel 41 and the side rod 4. Then, place the bottom angle steel positioning plate 60 above the bottom angle steel, position the middle support through the middle support positioning plate 30, and position the outer support through the outer support positioning plate 40. When positioning the middle support and the outer support, the hexagonal head bolt 301 passes through the roller rod slots opened on the middle support and the outer support to limit the front and rear positions of the middle support and the outer support.
