Referring to fig. 1-10, the present invention provides a technical solution:

a novel cylinder liner honing positioning device is characterized by comprising: the cylinder sleeve positioning disc comprises a cylinder sleeve positioning disc 1, a cylinder sleeve seat hole 3 is formed in the middle of the cylinder sleeve positioning disc 1, and grooves 2 are symmetrically formed in the cylinder sleeve positioning disc 1 on two sides of the cylinder sleeve seat hole 3.

The utility model discloses in the preferred embodiment, 2 cross-sections of recess are positive protruding type structures, 2 recess are close to 1 marginal end of cylinder liner positioning disk and are equipped with a circular counter bore 8, circular counter bore 8 links to each other with recess 2.

The utility model discloses a theory of operation and use flow are as follows:

1. the installation process comprises the following steps: firstly, the positioning bolt 4 is turned upside down, the nut of the positioning bolt is arranged in the groove 2, then the mounting hole in the middle of the positioning pressing block 5 penetrates through the positioning bolt 4, at the moment, the cylinder sleeve 7 is placed in the cylinder sleeve seat hole 3 and is pressed tightly by the positioning pressing block 5, and finally the positioning pressing block 5 is fixed on the positioning bolt 4 by the nut 6.

2. The use process comprises the following steps: the force that cylinder liner 7 received during honing is upper and lower direction, consequently, the effort that acts on the inner wall of cylinder liner 7 transmits positioning briquetting 5, again from positioning briquetting 5 transmit between positioning bolt 4 and the nut 6, this kind of structure is because positioning bolt 4 is invertedly set up in recess 2, the condition that the smooth tooth of cylinder liner positioning disk 1 damaged can not appear, consequently only can arouse smooth tooth between positioning bolt 4 and the nut 6, only need change positioning bolt 4 and nut 6 can, need not to change cylinder liner positioning disk 1, thereby reach the life who prolongs cylinder liner positioning disk 1, the frequency of maintenance change has been reduced, production time has been ensured, production efficiency has been improved, the purchase cost of cylinder liner positioning disk 1 has been reduced, the economic benefits of enterprise has been promoted, be favorable to the purpose of environmental protection.

3. Circular counter bore 8 links to each other with recess 2, changes positioning bolt 4 and can follow the circular counter bore 8 that links to each other with recess 2 and take out, also can follow the other end of recess 2 and take out, changes positioning bolt 4 convenient and fast more.
