Description

Technical Field

[0001] This utility model relates to the field of steel plate welding, specifically to a steel plate fixing device for a steel plate beveling machine. Background Technology

[0002] In the existing steel manufacturing industry, in order to better weld two steel plates, a steel plate beveling machine is usually used to grind and cut the bevel on the side to be welded. During the cutting process, in order to ensure that the steel plate does not have uneven cutting edges, a steel plate fixing device is usually used to fix the steel plate on the top and bottom to ensure the uniformity of the thickness of the bevel cut.

[0003] The existing steel plate fixing device for steel plate beveling machines typically refers to a driven roller located on one side of the top of the steel plate beveling machine and a driving roller located below the driven roller (the driven roller is located above the cutting wheel of the steel plate beveling machine, and the driving roller is located below the cutting wheel of the steel plate beveling machine; both the driven roller and the driving roller are fixed to the bracket at the top of the steel plate beveling machine using rotary bearings), and a positioning plate groove located below the driving roller. A height adjustment device is then fixed to the bottom surface of the positioning plate groove. The distance between the driven roller and the driving roller is adjusted by the height adjustment device to accommodate steel plates of different thicknesses.

[0004] Although the steel plate fixing device of this steel plate beveling machine can ensure that the steel plate will not have uneven cut thickness when cutting the beveling, if the position of the steel plate is not calibrated before cutting when processing long steel plates, the left and right beveling will be different during the processing. As the steel plate continues to move, this deviation will continue to increase, eventually leading to uneven beveling size. Utility Model Content

[0005] The technical problem this utility model aims to solve is that the existing steel plate fixing device for steel plate beveling machines can no longer continuously calibrate the left and right positions of the steel plate during processing, resulting in different bevel sizes during processing.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a steel plate fixing device for a steel plate beveling machine, including a steel plate beveling machine, a steel plate fixing mechanism is provided on one side of the steel plate beveling machine, the steel plate fixing mechanism includes a plurality of driven rollers located on one side of the housing of the steel plate beveling machine, a plurality of driving rollers located below the driven rollers, and a height adjustment device located below the lower driving rollers. A positioning plate groove for fixing the driving rollers is provided below the driving rollers. A steel plate limiting mechanism is provided on one side of the driving rollers. The steel plate limiting mechanism includes a limiting ring sleeved on the outer wall of the driving rollers and a spring located on one side of the limiting ring. A plurality of locking blocks are provided on the inner wall end of the limiting ring. The locking blocks pass through the side wall of the driving rollers. A spring groove for storing the springs is provided inside the driving rollers. A fixing screw for closing the spring groove is provided on one side of the spring groove. The fixing screw and the limiting ring are opposite to each other.

[0007] As an improvement, the sidewall of the positioning plate groove is connected to the driving roller and the driven roller is connected to the sidewall of the steel plate beveling machine through a rotary bearing, and the height adjustment device is connected to the bottom surface of the positioning plate groove through a pin structure.

[0008] As an improvement, the locking block and the fixing screws are all welded to both ends of the spring using an electric welding device.

[0009] As an improvement, a number of steel plate auxiliary wheels are provided on one side of the groove of the positioning plate, and the steel plate auxiliary wheels are on the same side as the fixing screw.

[0010] As an improvement, the steel plate auxiliary wheel is connected to the top surface of the groove of the positioning plate through a bolt structure.

[0011] As an improvement, a rotary motor that drives the active roller is provided on one side of the positioning plate groove.

[0012] The advantages of this invention compared with the prior art are as follows: This device installs a limiting ring on the cylindrical surface of the active roller, and slides the locking block of the inner ring of the limiting ring into the locking groove on one side of the active roller. In order to ensure that the limiting ring can always keep the cutting end of the steel plate tightly pressed against the straight line formed by the auxiliary wheel of the steel plate, a spring is installed in the spring groove on the side of the locking groove inside the active roller, and one side of the spring is welded to the locking block using an electric welding machine (in order to facilitate fixing the other end of the spring to the active roller, the other end of the spring will be welded to the fixing screw, and then the fixing screw will be screwed into the spring groove).

The rotary motor 26 is installed on one side of the drive roller 22, which is located directly below the cutting point of the steel plate beveling machine 1. The output shaft of the rotary motor 26 and the connecting shaft on one side of the drive roller 22 are usually connected by a connecting key. The side of the positioning plate groove 24 is welded with a fixing plate to support the rotary motor 26, and the rotary motor 26 is fixed to the fixing plate with screws. The output shaft of the height adjustment device 23 is inserted into the fixing hole on the bottom surface of the positioning plate groove 24, the pin holes of the two are aligned, and the pins are inserted for fixing. The position of the rotary motor 26 is on the opposite side of the cutting end of the steel plate beveling machine 1 (in order to facilitate the discharge of cutting debris, there is usually a chip discharge groove on the bottom surface of the positioning plate groove 24).

[0020] The positioning plate groove 24 has several steel plate auxiliary wheels 25 on one side of the groove opening. The steel plate auxiliary wheels 25 are connected to the top surface of the groove opening of the positioning plate groove 24 by bolt structure.
