[0010] Refer to the attached Figures 1 to 8 A further detailed description is given to an embodiment of the adjusting mechanism of a leveling machine according to the present invention.

[0011] An adjusting mechanism of a leveling machine includes an upper seat 1 and a base 2 which are oppositely arranged. An upper leveling roller and a lower leveling roller are respectively rotatably arranged on the upper seat 1 and the base 2. The upper leveling roller and the lower leveling roller are oppositely arranged and cooperate with each other to level the steel plate. Driving oil cylinders 3 for driving the upper seat 1 to move up and down are arranged at the four corners above the upper seat 1. The lower end of the output shaft 31 of the driving oil cylinder 3 passes through the upper seat 1 and is fixed on the base 2. Supporting assemblies 4 for supporting the upper seat 1 are arranged at the four corners between the upper seat 1 and the base 2. The supporting assembly 4 includes a lower supporting sleeve 41 and an upper supporting sleeve 42 which are both sleeved on the output shaft 31 and a driving motor 43 for driving the lower supporting sleeve 41 to rotate. The lower end of the upper supporting sleeve 42 is in threaded cooperation with the lower supporting sleeve 41, and a vertical guide groove 421 is arranged on the inner side wall of its upper end. The vertical guide groove 421 is matched with a vertical guiding member on the outer side wall of the output shaft 31. A transmission member 411 is connected to the lower end of the lower supporting sleeve 41. A plurality of tooth columns 4111 are circumferentially arranged at intervals on the transmission member 411. The tooth columns 4111 are meshed with the gear 431 on the output shaft 31 of the driving motor 43. The driving motor 43 drives the transmission member 411 to rotate through the gear 431, and drives the lower supporting sleeve 41 to rotate. The lower supporting sleeve 41 drives the upper supporting sleeve 42 to move vertically relative to the upper seat 1, so that the upper end of the upper supporting sleeve 42 is separated from or abutted against the lower end surface of the upper seat 1. When it is necessary to adjust the gap between the upper seat 1 and the base 2 of the leveling machine, only the upper seat 1 needs to be vertically moved by driving the oil cylinder 3; then the driving motor 43 drives the transmission member 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 vertically move 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 surface of the upper seat 1 to support the upper seat 1, realizing the adjustment of the relative position between the upper seat 1 and the base 2 of the leveling machine; when the tooth column 4111 on the transmission member 411 is damaged, only the tooth column 4111 needs to be taken out and replaced alone, without moving the upper seat 1 of the leveling machine; making the maintenance operation of the transmission member 411 more convenient, reducing the maintenance time, and at the same time reducing the maintenance cost.

[0012] A plurality of jacks 412 are circumferentially spaced at the lower end of the transmission member 411, and a plurality of receiving holes 413 are circumferentially spaced at the upper end thereof. The jacks 412 and the receiving holes 413 are arranged in one-to-one correspondence; the lower end of the tooth column 4111 passes through the receiving hole 413 and is placed in the jack 412, and the head at the upper end of the tooth column 4111 is placed in the receiving hole 413; facilitating the assembly operation of the tooth column 4111 on the transmission member 411, and at the same time facilitating the disassembly operation, saving the disassembly and assembly operation time of the tooth column 4111 on the transmission member 411; The upper and lower ends of the tooth column 4111 are respectively rotatably arranged in the jack 412 and the receiving hole 413, so that it is possible to avoid jamming between the transmission member 411 and the gear 431 without adding lubricating oil, and effectively reduce noise.

[0013] The receiving hole 413 at the upper end of the transmission member 411 is covered by a cover plate 5; a plurality of lower fixing holes 4112 are provided on the upper end surface of the transmission member 411, and a plurality of upper fixing holes 51 are provided on the cover plate 5. After the fastener passes through the upper fixing hole 51, it cooperates with the lower fixing hole 4112 to fix the cover plate 5 above the transmission member 411; making the tooth column 4111 more stably installed on the transmission member 411 and improving the stability of the leveling machine.

[0014] An inner keyway 4113 is provided on the inner side wall of the transmission member 411, and an outer keyway 414 is provided on the outer side wall of the lower support sleeve 41. The inner keyway 4113 and the outer keyway 414 are connected by a key to connect the lower support sleeve 41 and the transmission member 411 together to realize the linkage between the two.
