Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and more specifically, it relates to an adjustment mechanism for a leveling machine. Background Technology

[0002] A leveling machine is a device used to correct the flatness of steel plates. Its working principle is that the motor drives the upper and lower leveling rollers, which are set opposite each other, to rotate simultaneously. The steel plate is repeatedly twisted by the two sets of leveling rollers to eliminate the internal stress of the steel plate, thereby achieving the effect of flattening the steel plate.

[0003] Because steel plate thickness varies in practical applications; in order to enable the leveling machine to be used for leveling steel plates of different specifications, people have designed an adjustment function for the leveling machine; the existing leveling machine's adjustment mechanism is equipped with a gear, which meshes with a gear on the output shaft of the drive motor to achieve the transmission purpose, thereby realizing the leveling function of the leveling machine.

[0004] However, since the gears on the leveling machine's adjustment mechanism are mounted on the leveling machine, when the gears on the adjustment mechanism are damaged, the upper seat of the leveling machine needs to be removed before the gears on the adjustment mechanism can be replaced, which presents a troublesome replacement operation problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustment mechanism for a leveling machine.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An adjustment mechanism for a leveling machine includes an upper seat and a base arranged opposite to each other. Each of the four corners of the upper seat is equipped with a drive cylinder for moving the upper seat up and down. The lower end of the output shaft of each drive cylinder passes through the upper seat and is fixed to the base. Support assemblies for supporting the upper seat are provided at each of the four corners between the upper seat and the base. Each support assembly includes a lower support sleeve and an upper support sleeve, both sleeved on the output shaft, and a drive motor for rotating the lower support sleeve. The lower end of the upper support sleeve is threaded into the lower support sleeve, and its upper inner wall has a vertical guide groove that engages with a vertical guide member on the outer wall of the output shaft. The lower end of the lower support sleeve is connected to a transmission member, which has several circumferentially spaced toothed columns that mesh with gears on the output shaft of the drive motor.

[0008] The drive motor drives the transmission component to rotate via gears, which in turn drives the lower support sleeve to rotate. The lower support sleeve drives the upper support sleeve to move vertically relative to the upper seat, causing the upper end of the upper support sleeve to separate from or abut against the lower end face of the upper seat.

[0009] The present invention further provides that: the lower end of the transmission component is provided with a plurality of insertion holes spaced apart circumferentially, and the upper end is provided with a plurality of receiving holes spaced apart circumferentially, wherein the insertion holes and the receiving holes are provided in a one-to-one correspondence;

[0010] The lower end of the toothed post passes through the bearing hole and is placed inside the insertion hole, while the upper head of the toothed post is placed inside the bearing hole.

[0011] The present invention is further provided that the bearing hole at the upper end of the transmission component is covered by a cover plate;

[0012] The upper end face of the transmission component is provided with several lower fixing holes, and the cover plate is provided with several upper fixing holes. The fastener passes through the upper fixing holes and cooperates with the lower fixing holes to fix the cover plate above the transmission component.

[0013] The present invention further comprises: an inner keyway on the inner side wall of the transmission component and an outer keyway on the outer side wall of the lower support sleeve; the inner keyway and the outer keyway are connected by a key to connect the lower support sleeve and the transmission component together.

[0014] The beneficial effects of this utility model are as follows: When it is necessary to adjust the gap between the upper seat and the base of the leveling machine, it is only necessary to move the upper seat vertically by driving the hydraulic cylinder; then, the drive motor drives the transmission component to rotate through the gears, and drives the lower support sleeve to rotate. The lower support sleeve drives the upper support sleeve to move vertically relative to the upper seat to a suitable position, so that the upper end of the upper support sleeve abuts against the lower end face of the upper seat, supporting the upper seat and realizing the adjustment of the relative position between the upper seat and the base of the leveling machine; when the tooth column on the transmission component is damaged, it is only necessary to remove the tooth column separately for replacement, without moving the upper seat of the leveling machine; this makes the maintenance operation of the transmission component more convenient, reduces maintenance time, and lowers maintenance costs.

[0024] See attached document Figures 1 to 8 The present invention provides a more detailed description of an embodiment of the adjustment mechanism of a leveling machine.

[0025] An adjusting mechanism for a leveling machine includes an upper seat 1 and a base 2 arranged opposite to each other. An upper leveling roller and a lower leveling roller are rotatably mounted on the upper seat 1 and base 2, respectively, and are arranged opposite to each other to cooperate in leveling the steel plate. At each of the four corners of the upper seat 1, a drive cylinder 3 is provided to drive the upper seat 1 to move up and down. The lower end of the output shaft 31 of the drive cylinder 3 passes through the upper seat 1 and is fixed to the base 2. At each of the four corners between the upper seat 1 and the base 2, a support assembly 4 is provided to support the upper seat 1. The support assembly 4 includes components sleeved on... The output shaft 31 includes a lower support sleeve 41 and an upper support sleeve 42, as well as a drive motor 43 that drives the lower support sleeve 41 to rotate. The lower end of the upper support sleeve 42 is threadedly engaged with the lower support sleeve 41, and its upper end inner wall is provided with a vertical guide groove 421, which engages with a vertical guide member on the outer wall of the output shaft 31. The lower end of the lower support sleeve 41 is connected to a transmission member 411, which is provided with a plurality of toothed columns 4111 circumferentially spaced, and the toothed columns 4111 mesh with a gear 431 on the output shaft 31 of the drive motor 43.

[0026] The drive motor 43 drives the transmission component 411 to rotate through the gear 431, and drives the lower support sleeve 41 to rotate. The lower support sleeve 41 drives the upper support sleeve 42 to move vertically relative to the upper seat 1, so that the upper end of the upper support sleeve 42 is separated from or abuts against the lower end face of the upper seat 1.

[0027] When it is necessary to adjust the gap between the upper seat 1 and the base 2 of the leveling machine, the upper seat 1 only needs to be moved vertically by the drive cylinder 3; then the drive motor 43 drives the transmission component 411 to rotate through the gear 431, which in turn drives the lower support sleeve 41 to rotate. The lower support sleeve 41 drives the upper support sleeve 42 to move vertically relative to the upper seat 1 to a suitable position, so that the upper end of the upper support sleeve 42 abuts against the lower end face of the upper seat 1, supporting the upper seat 1 and realizing the adjustment of the relative position between the upper seat 1 and the base 2 of the leveling machine. When the toothed column 4111 on the transmission component 411 is damaged, it is only necessary to remove the toothed column 4111 separately for replacement, without moving the upper seat 1 of the leveling machine. This makes the maintenance of the transmission component 411 more convenient, reduces maintenance time, and lowers maintenance costs.

[0028] The transmission component 411 has a plurality of insertion holes 412 spaced apart on its lower end and a plurality of bearing holes 413 spaced apart on its upper end, with the insertion holes 412 and bearing holes 413 corresponding one-to-one; the lower end of the toothed column 4111 passes through the bearing hole 413 and is placed in the insertion hole 412, while the head of the upper end of the toothed column 4111 is placed in the bearing hole 413; this facilitates the assembly and disassembly of the toothed column 4111 on the transmission component 411, and saves the time required for assembly and disassembly of the toothed column 4111 on the transmission component 411;

[0029] The upper and lower ends of the gear 4111 are rotatably mounted in the insertion hole 412 and the bearing hole 413, respectively, so that no lubricating oil is needed to avoid jamming between the transmission component 411 and the gear 431, and the noise can be effectively reduced.

[0030] The bearing hole 413 at the upper end of the transmission component 411 is covered by the cover plate 5; the upper end face of the transmission component 411 is provided with a plurality of lower fixing holes 4112, and the cover plate 5 is provided with a plurality of upper fixing holes 51, wherein the fastener passes through the upper fixing holes 51 and cooperates with the lower fixing holes 4112 to fix the cover plate 5 above the transmission component 411; so that the tooth column 4111 can be installed more stably on the transmission component 411, thereby improving the stability of the leveling machine.

[0031] The inner wall of the transmission component 411 is provided with an inner keyway 4113, and the outer wall of the lower support sleeve 41 is provided with an outer keyway 414. The inner keyway 4113 and the outer keyway 414 are connected by a key to connect the lower support sleeve 41 and the transmission component 411 together, so as to realize the linkage between the two.

[0032] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
