In recent years, the development trend of the domestic round bale bundling machine is gradually good, a plurality of enterprises are in progress, but the cost is reduced and the failure rate is still a big problem for convenience of common people, wherein the bearing damage rate of the roller is a large part. The round bale bundling machine is mainly used for picking up, cutting up and packaging straws in a field, dust and grass scraps in a working environment are more, the dust and the grass scraps easily enter the roller, friction resistance caused by the dust and poor lubricating effect of the lubricant can be worn on the bearing, and when the wear reaches a certain degree, the bearing cannot operate and can only be replaced, so that the service life of the bearing is reduced. The problem is solved from the source and the entry of dust is reduced. When the bearing is assembled, the outer end face is sealed by the matched sealing device, and only a gap exists between the web disc and the inner wall of the roller, so that the gap between the web disc and the inner wall of the roller is reduced, the entry of dust is reduced, and the purpose of prolonging the service life of the bearing is achieved. However, after the gap between the two is reduced, the outer circular surface of the web disc is easy to collide with one side of the inner wall of the roller after being installed, the gap on one side is too large, even the two are directly collided, and the installation cannot be carried out, so that the coaxiality of the inner wall of the roller and the outer circular surface of the web disc is required to be ensured. Because the round bale bundling machine roller needs to process the inner wall of the roller after welding to ensure the coaxiality of the inner wall of the roller and the shaft head, and the spoke plates are installed and positioned through the shaft head, the coaxiality between the inner holes and the outer circles of the spoke plates is ensured at the moment, so that the outer circles of the spoke plates do not interfere with the inner wall of the roller when the roller rotates after the side spoke plates are assembled. If the coaxiality of the spoke plates is checked after the spoke plates are installed, the check is inconvenient, and if the spoke plates are found to be different in coaxiality, the spoke plates are required to be detached and replaced for reinstallation check, the installation and detachment process is complex, excessive manpower and time cost are required to be consumed, and the working efficiency is reduced.

Detailed Description
The present application is further described below with reference to the drawings and examples.
Referring to fig. 1 to 3, in an embodiment 1 of the present utility model, the present utility model provides an adjustable disc coaxiality inspection tool, which includes a base 1 and a sleeve 3 sleeved on the base 1. The base 1 is integrally cylindrical, a cylindrical bulge is arranged in the middle of the base 1, an annular bulge is arranged on the outer diameter part of the base, and the cross section of the base 1 is shaped like a Chinese character 'shan'. The whole hollow cylindrical shape that is of axle sleeve 3, the cylindrical arch in base 1 middle part is equal to axle sleeve 3 internal diameter size, the external diameter of axle sleeve 3 equals the internal hole diameter of spoke dish 2, and the protruding internal diameter of base 1 annular equals the external diameter of spoke dish 2. The central cylindrical bulge axis of the base 1 is collinear with the inner and outer circular axes of the shaft sleeve 3 and the annular bulge inner circular axis of the base 1. The outer diameter of the shaft sleeve 3 has a plurality of different sizes, and can meet the detection requirements of the discs 2 with different sizes. Preferably, a slope is arranged between the annular bulge of the base 1 and the middle cylindrical bulge, so that the sliding distance of the shaft sleeve 3 is reduced, and the detection efficiency is improved.
When the device is used, the base 1 is placed on a horizontal tabletop, after no foreign matters exist in the area between the annular bulge of the base 1 and the cylindrical bulge in the middle, the to-be-detected web disc 2 passes through the cylindrical bulge in the middle of the base 1 and is placed on the base 1, the outer circular surface of the web disc 2 is just in contact with the inner circular surface of the annular bulge of the base 1 without gaps, and if gaps exist or cannot be placed at the bottom, the web disc 2 is wrongly processed, and the web disc 2 is replaced for detection. Then selecting a shaft sleeve 3 matched with the diameter of the inner hole of the to-be-detected spoke plate 2, and installing the shaft sleeve 3 through a cylindrical bulge in the middle of the base 1, wherein if the shaft sleeve 3 passes through the inner hole of the spoke plate 2 and falls to the bottom of the base 1, the inner diameter and the outer circle of the spoke plate 2 are coaxial, so that the installation requirement is met; if the shaft sleeve 3 does not pass through the inner hole of the web disc 2 and falls on the web disc 2, the contact position of the inner hole of the web disc 2 and the shaft sleeve 3 is observed, and the selected shaft sleeve 3 is matched with the inner hole of the web disc 2, so that the condition that the outer diameter of the shaft sleeve 3 is larger than the inner diameter of the web disc 2 does not exist, the contact position of the web disc 2 and the shaft sleeve 3 is provided with a gap, and the side of the contact position is provided with no gap, at the moment, the position of the inner hole of the web disc 2 is proved to be deviated and not coaxial with the outer circle, and therefore, if the web disc 2 is installed and not coaxial with the inner wall of a roller, the web disc 2 is judged to be a defective product. During detection, the shaft sleeve 3 can be placed at the bottom of the base 1, the inner hole of the web disc 2 passes through the cylindrical bulge in the middle of the base 1, then the plane of the web disc 2 is pressed, whether the web disc is swayed or not is observed, the bottom surface is contacted with the base 1 or not, if swayed, the web disc is not installed to the bottom, the position of the inner hole of the web disc 2 has deviation, and is not coaxial with the inner wall of the roller, and otherwise coaxial. Both detection modes can check whether the discs 2 are coaxial or not, while the second mode is more time-saving and labor-saving for detecting discs of the same model in large batches.
As shown in fig. 4 to 5, in embodiment 2 of the present utility model, the same parts as those of embodiment 1 are not repeated, and the difference from embodiment 1 is that in embodiment 2, a plurality of adjusting rings 4 are added at the annular protrusion of the base 1. The adjusting ring 4 is sleeved at the inner circle of the annular bulge of the base 1, and can be mutually spliced to meet the detection requirements of the discs 2 with different outer diameters.
As shown in fig. 6 to 7, in embodiment 3 of the present utility model, the difference between the embodiment 1 and embodiment 2 is that a plurality of adjusting blocks 5 are added, the adjusting blocks 5 are disposed at the inner circle of the annular protrusion of the base 1, the whole is arc-shaped, the outer circle surface of the adjusting blocks 5 can be attached to the inner circle surface of the annular protrusion of the base 1, the push rod 6 horizontally passes through the annular protrusion of the base 1 and is fixedly connected with the adjusting blocks 5, each adjusting block 5 is fixedly connected with a push rod 6, and a limit screw 7 is vertically disposed at the corresponding position of the annular protrusion of the base 1, so as to prevent the deviation of the detection result caused by the displacement of the push rod 6 in the detection process. The adjusting block 5 is made of a complete circular ring which is cut in equal parts and cut off at a certain angle.
In addition to the above embodiments, other embodiments may be provided, and all technical solutions formed by equivalent substitution or equivalent transformation are within the scope of protection claimed in the present application.
