[0001] The application relates to a correcting device, in particular to a quick correcting spline shaft coupling device of a multi-roller straightening machine, and belongs to the technical field of installation of a multi-roller straightening machine of a thick plate pickling unit. BACKGROUND

[0002] The thick plate pickling unit of Meigang is a newly put into operation unit. During the debugging and production stage, the multi-roller straightening machine often has roll printing defects, the roll surface of the straightening machine work roller needs to be polished, and then the straightening machine needs to be reassembled. There are 13 work rollers in the upper and lower roller boxes of the straightening machine. In the early stage, due to the lack of tooling, the reassembly time is as high as several hours for many times, which seriously affects the debugging and production plan of the unit. Therefore, there is an urgent need for a new scheme to solve the above installation technical problems. SUMMARY

[0003] The application is exactly aimed at the problems existing in the prior art, and provides a quick correcting spline shaft coupling device of a multi-roller straightening machine. The technical scheme mainly solves the technical problem of long reassembly time of the existing multi-roller straightening machine roll box. The device can quickly correct the position of the spline shaft coupling of the straightening machine, improve the accuracy of the butt joint of the work roller of the upper and lower roller boxes of the straightening machine and the spline shaft coupling, and thus improve the labor efficiency.

[0004] In order to achieve the above-mentioned purpose, the technical scheme of the application is as follows: a quick correcting spline shaft coupling device of a multi-roller straightening machine, the device comprises an inner spline shaft, an outer spline shaft, a quick connector, an inner spline wrench, a locking nut and a spline wrench handle, the inner spline shaft and the outer spline shaft are engaged with each other, have equal lengths and a 300mm engagement length, and can slide relative to each other, the inner spline shaft is connected with the inner spline wrench through the quick connector, the inner spline wrench is connected with the spline wrench handle through threads, and the locking nut is arranged.

[0005] As an improvement of the application, the inner spline shaft and the outer spline shaft are engaged with each other, have equal lengths and a 300mm engagement length. In the limited space, the total width of the inner spline shaft and the outer spline shaft is up to 500mm, the distance between the roll box and the coupling is 400mm, and thus the personnel can safely operate the correcting device.

[0006] As an improvement of the application, in order to facilitate the operation of the operator, the inner spline shaft and the outer spline shaft are made of plastic material (lightweight, one person can operate independently), the inner spline wrench is made of steel material, the inner spline wrench is separated from the quick connector, and the inner spline wrench is used to rotate the work roller of the straightening machine through the inner spline wrench and the spline wrench handle, so as to correct the position of the spline shaft coupling of the straightening machine one by one.

[0007] As an improvement of the application, the inner spline wrench handle and the locking nut are detachable and connected with the inner spline wrench through threads.

[0008] As an improvement of the present application, the external spline shaft can reversely impact on the shaft head of the work roll of the straightener, so that the correcting device can be quickly separated from the shaft head of the work roll of the straightener.

[0009] A method for quickly correcting the spline coupling of a multi-roll straightener,

[0010] Step 1) First, the driving motor is jogged to drive the chain to move the upper and lower roll boxes of the straightener body to be close to the inner spline coupling by 400 mm;

[0011] Step 2) The operator drives the multi-shaft spline coupling positioning device to realize accurate positioning of the upper and lower inner spline couplings;

[0012] Step 3) The operator enters the rack to install the quick correction multi-roll straightener spline coupling device, extracts the external spline shaft, inserts it into the inner spline of the spline coupling, and passes through if there is no jam. If it cannot be inserted into the inner spline of the spline coupling, the external spline shaft is rotated by using the inner spline wrench and the spline wrench handle, thereby driving the work roll of the straightener, and the insertion is repeated until there is no jam, so as to complete the positioning of the spline coupling of the straightener. The spline wrench handle is installed close to the side of the work roll (for easy disengagement of the rotating work roll), and then the outer spline positions of the shaft heads on the drive side of each work roll are corrected one by one to avoid interference, so that each work roll is accurately inserted into the inner spline coupling;

[0013] Step 4) After step 3 is completed, the driving motor is jogged again to make the multi-roll spline coupling butt joint. Check if there is a top tooth phenomenon (use a welding rod bent at 90° and inserted into the spline coupling. If it cannot be inserted normally, repeat step 3.

[0014] Step 5) After the multi-roll spline coupling is successfully inserted, first open the transmission shaft brake, rotate the transmission shaft in the forward and reverse directions respectively to eliminate the meshing interference resistance, then slightly open the spline coupling positioning device to make the spline coupling in a free state, and finally drive the motor again to drive the chain to make the work rolls of the upper and lower roll boxes of the straightener be inserted into the inner spline coupling.

[0015] Step 6) Open the multi-shaft spline coupling positioning device completely, return to the initial position, and fix the upper and lower roll boxes of the straightener body respectively;

[0016] Step 7) Finally, the work rolls of the straightener are corrected to zero, and the operation is completed.

[0017] Compared with the prior art, the present application has the following advantages: the technical scheme solves the technical problem of long roll box reloading time of the existing multi-roll straightening machine, the device can quickly correct the position of the spline coupling of the straightening machine, improves the accuracy of the butt joint of the working roll of the upper and lower roll boxes of the straightening machine and the spline coupling, thereby improving the labor efficiency and ensuring the maintenance time. At the same time, in order to ensure the convenience and safety of the operation of the operator, the material and its strength of the spline coupling device of the multi-roll straightening machine are carefully selected, and the personnel standing position and space arrangement in the limited space are obtained through multiple practices. The technology fills the gap in this process, cleverly uses the quick connector, integrates two materials into one, realizes the respective functions, achieves the expected effect, can obtain good social benefits, and is worth popularizing and using in the same industry.

DETAILED DESCRIPTION

[0024] In order to deepen the understanding of the present application, the present embodiment will be described in detail below with reference to the accompanying drawings.

[0025] Example 1: see Figure 1 — Figure 5The application discloses a quick calibration multi-roller straightening machine spline coupling device, which comprises an inner spline shaft 9, an outer spline shaft 10, a quick joint 11, an inner spline wrench 12, a locking nut 13 and a spline wrench handle 14. The inner spline shaft 9 and the outer spline shaft 10 are engaged with each other, have equal lengths and a 300mm engagement length, and can slide relative to each other. The inner spline shaft 9 is connected with the inner spline wrench 12 through the quick joint 11, the inner spline wrench 12 is connected with the spline wrench handle 14 through screw threads, and the locking nut 13 is arranged. The inner spline shaft 9 and the outer spline shaft 10 are engaged with each other, have equal lengths and a 300mm engagement length. In a limited space, the total width of the inner spline shaft 9 and the outer spline shaft 10 can reach 500mm, the distance between the roller box and the coupling is 400mm, and thus the personnel can safely operate the calibration device. In order to facilitate the operation of the personnel, the inner spline shaft 9 and the outer spline shaft 10 are made of plastic, and the inner spline wrench 12 is made of steel. The inner spline wrench 12 is separated from the quick joint 11 and acts on the straightening machine working roller alone. The inner spline wrench handle 14 and the locking nut 13 can be disassembled and connected with the inner spline wrench through screw threads. The outer spline shaft 10 can reversely impact on the straightening machine working roller shaft head, so that the calibration device can be quickly separated from the straightening machine working roller shaft head.

[0026] In the scheme, the straightening machine comprises two upper and lower roller boxes, the straightening machine enters the machine rack through a driving motor and a chain, the straightening machine roller box has a plurality of working rollers, the working roller transmission side shaft head is an outer spline shaft, and the straightening machine upper and lower roller boxes can rotate only when the working roller transmission side shaft head is accurately inserted into the inner spline coupling and the transmission shaft is driven by the transmission motor, so that the straightening machine upper and lower roller boxes can rotate to straighten the steel strip and improve the plate shape. If the position of the outer spline of the working roller transmission side shaft head of the straightening machine roller box is not calibrated, the straightening machine roller box cannot be smoothly completed, and the working space in the machine rack is small. The quick calibration multi-roller straightening machine spline coupling device can improve the accuracy of the connection between the working rollers of the straightening machine upper and lower roller boxes and the spline coupling, and improve the labor efficiency. When the straightening machine body upper and lower roller boxes are moved to be close to the inner spline coupling, the device is installed on the working roller transmission side shaft head of the straightening machine, at this time, the outer spline shaft is extended to be matched with the inner spline coupling. When the matching is not good, the locking nut, the inner spline wrench handle and the inner spline wrench are connected, the quick joint is separated, and the working roller of the straightening machine roller box can be rotated, so that the accuracy of the connection between the working rollers of the straightening machine upper and lower roller boxes and the spline coupling is improved, and the labor efficiency is improved. The inner spline shaft and the outer spline shaft are engaged with each other, have equal lengths and can slide relative to each other. The inner spline shaft is connected with the inner spline wrench through the quick joint.

[0027] Embodiment 2: see Figure 1 — Figure 5The application relates to a method for quickly correcting a multi-roller straightening machine spline coupling, and the method comprises the following steps:

[0028] Step 1) first, a driving motor 1 is jogged to drive a chain 2 to move a straightening machine body upper and lower roller boxes 3 to a position close to the inner spline coupling by 400 mm;

[0029] Step 2) an operator drives a multi-axle spline coupling positioning device 4 to realize accurate positioning of the upper and lower inner spline couplings;

[0030] Step 3) the operator enters the rack to install the quick correction multi-roller straightening machine spline coupling device, draws out an outer spline shaft 10, inserts the outer spline shaft into the inner spline of the spline coupling, and passes through if no jamming occurs; if the outer spline shaft cannot be inserted into the inner spline of the spline coupling, the outer spline shaft 10 is rotated through an inner spline wrench 12 and a spline wrench handle 14, thereby driving the straightening machine working roller, and the insertion is repeated until the insertion is completed without jamming, so that the position of the straightening machine spline coupling is corrected; the inner spline wrench handle is installed close to the working roller side (to facilitate the disengagement of the rotating working roller), and then the outer spline positions of the working roller transmission side shaft heads are corrected one by one to avoid interference, so that each working roller is accurately inserted into the inner spline coupling;

[0031] Step 4) after step 3 is completed, the driving motor 1 is jogged again to make the multi-roller spline coupling butt joint; the existence of the top tooth phenomenon (a welding rod is bent into 90 degrees and inserted into the spline coupling, and the normal insertion cannot be performed) is checked; if the jamming and the non-insertion exist, the step 3 operation is repeated.

[0032] Step 5) after the multi-roller spline coupling is successfully inserted, the transmission shaft holding brake 7 is first opened, the transmission shaft is rotated in the forward direction and the reverse direction respectively to eliminate the meshing interference resistance, then the spline coupling positioning device is slightly opened to make the spline coupling in a free state, and finally the driving motor drives the chain to make the straightening machine upper and lower roller boxes work rollers all be inserted into the inner spline coupling.

[0033] Step 6) the multi-axle spline coupling positioning device 4 is completely opened, and the initial position is returned; the straightening machine body upper and lower roller boxes 3 are respectively fixed;

[0034] Step 7) finally, the straightening machine working roller is zeroed, and the operation is completed.

[0035] It is to be noted that the above embodiment is not used to limit the protection scope of the application, and equivalent transformations or substitutions made on the basis of the above technical solution all fall within the protection scope of the application claims.
