AI Technical Summary
The existing guide rollers have a fixed spacing, which cannot adapt to slight changes in the width of the workpiece, resulting in clamping that is too tight or too loose, failing to meet the requirements of steel rolling.
Design an eccentric shaft adjustment device that achieves continuous adjustment of eccentricity through a combination structure of eccentric disc and adjustment hole. Use a connection method of fixing bolts and nuts to ensure that the eccentric disc is reliably fixed on the adjustment disc.
This technology enables continuous adjustment of the eccentricity to meet steel requirements even with slight changes in the width of the rolled piece, thereby improving the stability and safety of steel section rolling.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of section steel processing, and in particular relates to an adjusting device for an eccentric shaft. Background Art
[0002] A guide is a device installed before and after the roll hole during the steel rolling process to help the rolled piece enter and exit the roll hole accurately and stably in a predetermined direction and state.
[0003] In the past, the distance between the two guide rollers of this structure was fixed. When there was a slight change in the width of the rolled piece, the clamping was either too tight or too loose, which could not meet the requirements of steel rolling. Therefore, an eccentric shaft adjustment device is now needed. Utility Model Content
[0004] The purpose of the utility model is to provide an eccentric shaft adjustment device with a simple structure and reasonable design in order to solve the above problems.
[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:
[0006] An adjustment device for an eccentric shaft comprises a main shaft, one end of the main shaft is integrally provided with an adjustment disk, one side of the adjustment disk is eccentrically provided with an eccentric disk, a plurality of adjustment holes are provided on the eccentric disk, a plurality of slots are provided on the inner side of the adjustment disk, and fixing bolts that are plugged into and matched with the adjustment holes are movably provided on the inner sides of the plurality of slots.
[0007] As a further optimization solution of the utility model, the longitudinal and transverse lines connecting the center points of the plurality of adjustment holes form a "cross" structure.
[0008] As a further optimization scheme of the utility model, the distances between the center points of the plurality of adjustment holes and the center points of the eccentric disks are connected in sequence from near to far to form a vortex line.
[0009] As a further optimization solution of the present utility model, there are two card slots, which are symmetrically arranged.
[0010] As a further optimization solution of the utility model, the clamping slot adopts a "T"-shaped structure, and one end of the clamping slot passes through the arc surface of the adjustment disk.
[0011] As a further optimization solution of the utility model, the threaded end of the fixing bolt passes through the adjustment hole and is connected to a fixing nut that fixes the eccentric disk on the adjustment disk.
[0012] The beneficial effect of the utility model is that in the utility model, the nut at one end of the fixing bolt slides on the inner side of the slot, so that the fixing bolt can be plugged into any adjusting hole on the eccentric disk, and then the nut is connected to the fixing bolt, so that the eccentric disk can be eccentrically fixed on one side of the adjusting disk, and the eccentricity can be adjusted. The distances of the connecting lines of the center points of the eccentric disks through the center points of several adjusting holes are connected in sequence from near to far to form a vortex line, so that the eccentricity can be continuously adjusted, and when there is a slight change in the width of the rolled piece, the steel passing requirement can also be met.

[0019] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.
[0020] Example 1
[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The eccentric shaft adjustment device shown in the figure comprises a main shaft 1 and an adjusting disk 2 integrally arranged with one end of the main shaft 1, an eccentric disk 4 is eccentrically arranged on one side of the adjusting disk 2, and a plurality of adjusting holes 5 are provided on the eccentric disk 4, and two clamping grooves 3 are provided on the inner side of the adjusting disk 2, and the two clamping grooves 3 are symmetrically arranged, and the clamping groove 3 adopts a "T"-shaped structure, through which the nut of the fixing bolt 7 can be clamped into the inner side of the clamping groove 3 and can be moved arbitrarily, and one end of the clamping groove 3 passes through the arc surface of the adjusting disk 2, so that the fixing bolt 7 can slide out from the inner side of the clamping groove 3, and the fixing bolt 7 is easy to replace after long-term use, and the fixing bolt 7 is prevented from being strained and affecting the safety of steel rolling, and the inner sides of the plurality of clamping grooves 3 are movably provided with fixing bolts 7 plugged and matched with the adjusting holes 5, and the threaded end of the fixing bolt 7 passes through the adjusting hole 5 to connect the fixing nut 6, and the eccentric disk 4 can be fixed to one side of the adjusting disk 2 through the connection between the fixing nut 6 and the fixing bolt 7, which is convenient for installation.
[0022] like Figure 1 , Figure 4 As shown, the distances of the center points of the plurality of adjustment holes 5 and the center lines of the eccentric disk 4 are connected in sequence from near to far to form a vortex line 8, and the longitudinal and transverse lines of the center points of the plurality of adjustment holes 5 form a "cross" structure. By connecting the plurality of adjustment holes 5 in sequence to form a vortex line 8, the eccentricity can be adjusted continuously, and the steel passing requirement can be met when there is a slight change in the width of the rolled piece. For example, when the eccentricity is set to 4mm, the adjustment range of the distance between the two guide rollers becomes ±8mm, so that the steel passing requirement can be met within a deviation of 8mm in the width of the rolled piece.
[0023] It should be noted that when using this eccentric shaft adjustment device, first pass the adjustment hole 5 on the eccentric disk 4 through the fixing bolt 7, and then fix the fixing nut 6 to one end of the fixing bolt 7, so that the eccentric disk 4 can be eccentrically fixed to one side of the adjustment disk 2 according to a certain eccentric distance. When there is a slight change in the width of the rolled piece, the steel passing requirement can also be met.
[0024] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
