Description

Technical Field

[0001] The utility model relates to the technical field of billet positioning, in particular to a billet positioning device. Background Technique

[0002] During production, the specified length range of the charged billets is between 2.3 meters and 3.5 meters, and the length changes frequently. To ensure that the charged billets are centered and prevent the billets from being loaded off-center, the positions of the billets need to be adjusted frequently.

[0003] The existing Chinese utility model patent with the reference publication number of CN217666806 discloses a positioning device for billet cutting, including a base and a first fixing plate. At the inner wall position of the upper end of the base, there are a first sliding groove and a second sliding groove. At the front surface position of the first fixing plate, there is an anti-slip pad A. At the left surface position of the movable clamping plate, there is an anti-slip pad B. At the front and rear sides of the bottom of the movable clamping plate, there are sliding blocks. At the front and rear sides of the sliding blocks, there are rolling beads. The screw hole of the second fixing plate and the movable clamping plate are connected by a pull rod. At the top position of the right end of the pull rod, there is an adjusting screw knob. At the top position of the left end of the pull rod, there is a raised block, which can increase the positioning of the workpiece clamping, and can also avoid the workpiece deformation caused by excessive clamping force, and can well avoid scratches on the appearance shape surface of the workpiece, make the movable clamping plate more flexible in movement during adjustment, improve the efficiency of the entire processing operation, and at the same time reduce the labor intensity of the staff.

[0004] The existing billet positioning device generally uses screw drive. When the positioning device pushes the billet to move, the screw will bear a large force, and the screw is prone to problems such as slipping threads, and the service life of the screw is short, resulting in the device needing to be regularly overhauled and maintained. At the same time, this method is very inconvenient as it requires manual use of a connecting rod to drive. Summary of the Utility Model

[0015] Compared with the prior art, the utility model provides a billet positioning device, which has the following beneficial effects:

[0016] 1. Through the setting of the slide rails, the slide rails are symmetrically installed on the inner sides of the support frames on the left and right. A sliding connection is formed between the sliders and the slide rails. The balls are fitted and installed under the sliders. The positions of the balls are restricted by the limiting plates. The bottom ends of the balls are located below the limiting plates and in contact with the sliders. The balls can reduce the relative friction between the sliders and the slide rails. The roller frames are fixedly installed above the sliders and can slide above the slide rails through the sliders. The racks are fixedly installed on the left and right sides of the bottom surface of the roller frames through connecting plates. The racks are meshed with the driving gears. The driving gears are inserted and installed outside the output shafts of the gearboxes. The gearboxes are driven by driving motors. The distance measuring instruments are symmetrically installed on the front and back sides of the support frames in a front-back mirror image with the center of the support frames as the reference. The controller can control the rotation direction and startup duration of the driving motor according to the detection data of the distance measuring instruments. When in use, the distance measuring instruments can detect the distances between the front and back sides of the support frames and the two sides of the billet. The controller can output the startup duration and direction of the driving motor according to the values of the distance measuring instruments on both sides. After the driving motor starts, it drives the gearbox to rotate. The gearbox can increase the output torque of the driving motor, so that the driving gears rotate with a greater torque, so as to drive the roller frames to move back and forth, thereby adjusting the left-right position of the billet. When the detection data of the distance measuring instruments on both sides are the same, the driving motor stops rotating, so that the billet is located at the center of the support frame. This method can reduce manual operation during adjustment, so as to adjust the billet position more quickly.

[0017] 2. Through the setting of the balls, the driving gears drive the racks to move, so that the billets above the roller frames and the supporting rollers move. Since the gravity of the billets is only transmitted to the balls, there is no vertical relative pressure between the driving gears and the racks. The balls can reduce the relative friction between the sliders and the slide rails to reduce the influence of the friction on the movement of the sliders. After the sliders bear the gravity of the billets, they can move easily, so that when the driving gears rotate, they only generate lateral forces with the racks, thereby reducing the wear rate of the driving gears and the racks, so as to improve the service life.

A support roller 21 is movably installed inside the roller frame 2. A connecting plate 22 is fixedly installed below the roller frame 2. The rack 23 is fixedly installed below the connecting plate 22.

[0032] The roller frame 2 is symmetrically installed at the front and rear ends of the slider 17 with the center of the slider 17 as the reference. The support rollers 21 are equidistantly installed on the left and right inside the roller frame 2. A rotational connection is formed between the support rollers 21 and the roller frame 2.

[0033] The bottom surface of the roller frame 2 is fixedly connected to the top surface of the slider 17. The roller frame 2 forms a sliding connection through the slider 17 and the slide rail 16.

[0034] The connecting plate 22 is symmetrically installed on the left and right sides of the roller frame 2 with the center of the roller frame 2 as the reference. The rack 23 is symmetrically installed on the bottom surfaces of the connecting plates 22 on the left and right sides below the roller frame 2 with the center of the roller frame 2 as the reference, and the rack 23 meshes with the driving gear 15.

[0036] In use, the slide rails 16 are symmetrically installed on the inner side of the support frame 1 from left to right. A sliding connection is formed between the slider 17 and the slide rails 16. The balls 18 are fitted and installed below the slider 17. The position of the balls 18 is restricted by the limiting plate 19. The bottom ends of the balls 18 are located below the limiting plate 19 and in contact with the slider 17. The balls 18 can reduce the relative friction between the slider 17 and the slide rails 16. The roller frame 2 is fixedly installed above the slider 17 and can slide above the slide rails 16 through the slider 17.

The controller 110 can output the startup duration and direction of the driving motor 13 according to the values of the distance measuring instruments 11 on both sides. After the driving motor 13 starts, it drives the gear box 14 to rotate. The gear box 14 can increase the output torque of the driving motor 13, so that the driving gears 15 rotate with a greater torque, so as to drive the roller frame 2 to move back and forth, thereby adjusting the left and right positions of the steel billet. When the detection data of the distance measuring instruments 11 on both sides are the same, the driving motor 13 stops rotating, so that the steel billet is located at the center of the support frame 1. This method can reduce the manual operation during adjustment, so as to adjust the position of the steel billet more quickly. By driving the racks 23 to move through the driving gears 15, the steel billet above the roller frame 2 and the support rollers 21 moves. Since the gravity of the steel billet is only transmitted to the balls 18, there is no vertical relative pressure between the driving gears 15 and the racks 23. The balls 18 can reduce the relative friction between the slider 17 and the slide rails 16 to reduce the influence of the friction on the movement of the slider 17, so that the slider 17 can move easily after bearing the gravity of the steel billet, so that only a lateral acting force is generated between the driving gears 15 and the racks 23 when the driving gears 15 rotate, thereby reducing the wear rate of the driving gears 15 and the racks 23 and improving the service life.
