[0033] The support includes a fixed plate 1 and a clamp 3, with the clamp 3 located at one end of the fixed plate 1;

[0034] The connector is used to complete the assembly between the fixed plate 1 and the clamp 3. The outer sides of both ends of the connector are threaded with a second nut 15, which allows the connector to fix the fixed plate 1 and the clamp 3.

[0035] The connecting parts are: the first double-ended bolt 2, which is suitable for the WS119.08.184 clutch cylinder liner; the second double-ended bolt 9, which is suitable for the WS119.08.217 / 188 clutch cylinder liner; the third double-ended bolt 10, which is suitable for the WS119.08.369 clutch cylinder liner; and the fourth double-ended bolt 11, which is suitable for the WS119.08.215 clutch cylinder liner.

[0036] The positioning component is located on the inner side of the fixed plate 1 near the clamp 3. The outer side of the positioning component and the end of the fixed plate 1 away from the clamp 3 are threaded with a first nut 12. The positioning component is assembled with the fixed plate 1 by the first nut 12, so that different outer circles can be machined by different positioning components.

[0037] The positioning component is the third positioning pin 8, which enables the cylinder liner to be machined on its outer diameter; the positioning component is the second positioning pin 6, which enables the cylinder liner to be machined on its outer diameter at one end; and the positioning component is the first positioning pin 5, which enables the cylinder liner to be machined on its outer diameter at the other end.

[0038] A pressure plate 7 is provided at the end of the clamp 3 away from the fixed plate 1. The pressure plate 7 and the clamp 3 are assembled by a fastener, and the fastener and the positioning element are threadedly connected. Thus, the pressure plate 7 can be fixed at one end of the clamp 3 by assembling the fastener and the positioning element.

[0039] The fasteners are: a first bolt 13, one end of which passes through the pressure plate 7 and the clamp 3 and is threaded to the third positioning pin 8, thereby fixing the position of the pressure plate 7 and assisting in machining the outer diameter of the cylinder liner; a second bolt 14, one end of which passes through the pressure plate 7 and the clamp 3 and is threaded to the second positioning pin 6, thereby fixing the position of the second positioning pin 6 and assisting in machining the outer diameter of one end of the cylinder liner; and a double-ended bolt 4, one end of which passes through the pressure plate 7 and the clamp 3 and is threaded to the first positioning pin 5, and the other end of the double-ended bolt 4 is threaded with a third nut 16, thereby fixing one end of the double-ended bolt 4 to the first positioning pin 5, and fixing the pressure plate 7 and the clamp 3 together through the third nut 16 on the outside of the second bolt 14, thus assisting in machining the outer diameter of the other end of the cylinder liner.

[0041] When machining the outer diameter of the cylinder liner, the third positioning pin 8 is selected as the positioning component and the first bolt 13 is selected as the fixing component. The third positioning pin 8 is then installed on the end of the fixed plate 1 near the clamp 3 through the first nut 12. The fixed plate 1 and the clamp 3 are then assembled through the corresponding connecting parts. The pressure plate 7 is then placed on the end of the clamp 3 away from the fixed plate 1, and the pressure plate 7 is fixed by the threaded connection between the first bolt 13 and the pressure plate 7 and the clamp 3 and the third positioning pin 8.

[0042] When machining the outer diameter of one end of the cylinder liner, the second locating pin 6 is selected as the positioning component, and the second bolt 14 is selected as the fixing component. The second locating pin 6 is then installed on the end of the fixing plate 1 near the clamp 3 using the first nut 12. The fixing plate 1 and the clamp 3 are then assembled using corresponding connecting components. The pressure plate 7 is then placed on the end of the clamp 3 away from the fixing plate 1, and the pressure plate 7 is fixed by the threaded connection between the second bolt 14 and the pressure plate 7 and the clamp 3 to the third locating pin 8. When machining the outer diameter of the other end of the cylinder liner, this… When selecting the positioning component as the first positioning pin 5 and the fixing component as the clamping double-ended bolt 4, the first positioning pin 5 is installed on the end of the fixed plate 1 near the clamp 3 through the first nut 12. At this time, the fixed plate 1 and the clamp 3 are assembled through the corresponding connecting parts. Then, the pressure plate 7 is placed on the end of the clamp 3 away from the fixed plate 1, and the pressure plate 7 is fixed by threading one end of the clamping double-ended bolt 4 through the pressure plate 7 and the clamp 3 to the third positioning pin 8, and the pressure plate 7 is fixed by the third nut 16 threaded to the other end of the clamping double-ended bolt 4.
