For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following will explain the implementation manners according to the overall structure of the present utility model.

[0028] Referring to Figure 1 as shown, an embodiment of the present application provides a cylinder block processing tooling, including:

[0029] A base 1, the base 1 has a central axis, and the base 1 is used for placing the cylinder block 2;

[0030] A plurality of mounting holes 11 provided on the base 1, the plurality of mounting holes 11 are symmetrically opened on both sides of the central axis, and the plurality of mounting holes 11 are symmetrically distributed in a direction away from the central axis;

[0031] Any mounting hole 11 has a first end 111 and a second end 112 that are far away from each other. The first end 111 of any mounting hole 11 is connected to a bottom cover 3, and the second end 112 of any mounting hole 11 is connected to a limiting part 4. An elastic member 5 is installed between any bottom cover 3 and its corresponding limiting part 4;

[0032] The side walls of the cylinder block 2 distributed on both sides of the central axis are respectively in contact with the side walls of the adjacent limiting parts 4, and are used for limiting the cylinder block along the direction perpendicular to the central axis.

[0033] According to Figure 1 , those skilled in the art fix and place the cylinder block 2 through the base 1. Among them, the base 1 has a central axis, and a plurality of mounting holes 11 are distributed on both sides of the central axis. By arranging the limiting parts 4 in the mounting holes 11, the positioning of the cylinder block 2 can be completed.

[0034] Specifically, in the above structure, a plurality of mounting holes 11 are symmetrically distributed on both sides of the central axis. Those skilled in the art set a first end 111 and a second end 112 that are far away from each other on any one mounting hole 11.

[0035] Furthermore, those skilled in the art can set a bottom cover 3 on the first end 111 of the mounting hole, so as to seal the second end of the first end 111. Preferably, the bottom cover 3 is connected to the first end 111 by threads. Even further, those skilled in the art can also set a limiting part 4 in the second end 112 of the mounting hole. It can be understood that a part of the limiting part 4 is arranged in the mounting hole, and the other part is arranged outside the mounting hole.

[0036] In order to enable the limiting part 4 to position cylinder blocks 2 of various sizes, those skilled in the art can arrange an elastic member 5 between the limiting part 4 and the bottom cover 3. That is, the two ends of the elastic member 5 are respectively in contact with the limiting part 4 and the bottom cover 3.

[0037] With the above structure, under the action of the elastic member 5, the limiting part 4 is in a state of passing through the mounting hole 11. When the side of the cylinder block 2 facing the base 1 presses against the top of the limiting part 4, the limiting part 4 can be pressed into the mounting hole 11. When the side of the cylinder block 2 facing the base 1 does not press against the top of the limiting part 4, the limiting part 4 is in a state of passing through the mounting hole 11.

[0038] After the cylinder block 2 is fixed, the limiting part 4 and the cylinder block 2 are in contact with each other. Specifically, when the cylinder block 2 is in a fixed state, the side wall of the limiting part 4 and the side wall of the cylinder block 2 are in contact with each other. The wall surface of the cylinder block 2 facing the base 1 is completely in close contact with the base 1, so that the middle position of the cylinder block 2 can be determined more accurately.

[0039] In summary, those skilled in the art have provided mounting holes 11 on both sides of the middle axis on the side wall of the base 1. A bottom cover 3, a limiting portion 41, and an elastic member are provided in the mounting holes 11, so that cylinders 2 of different sizes can be fixed. At the same time, the middle axis of the base 1 can be used to conveniently determine the center position of cylinders 2 of different sizes.

[0040] It can be understood that the above operations avoid the redundant tool setting operations after placing and fixing cylinders 2 of multiple specifications, and thus can effectively improve the processing efficiency of cylinders 2.

[0041] In the above setting, preferably, those skilled in the art can set the ends of multiple limiting portions 4 away from the mounting holes 11 as arc surfaces. That is, in the above embodiment, there are cases where the cylinder 2 directly abuts against the ends of the limiting portions 4 away from the mounting holes 11, and there are also cases where the cylinder 2 contacts and rubs against the limiting portions 4. In this embodiment, setting the ends of multiple limiting portions 4 away from the mounting holes 11 as arc surfaces can effectively prevent the material on the cylinder 2 from being damaged by the limiting portions 4 during installation.

[0042] By setting the ends of multiple limiting portions 4 away from the mounting holes 11 as described above, the cylinder can be effectively prevented from failing during installation, and thus the rejection rate of cylinder processing can be reduced.

[0043] In the above setting, those skilled in the art provide an elastic member 5 between the bottom cover 3 and the limiting portion 4. Preferably, a receiving groove 41 is provided on the end side of any limiting portion 4 facing the elastic member 5 for receiving the end of the elastic member 5. According to Figure 2 , the end of the elastic member 5 facing the limiting portion 4 is received in the receiving groove 41, so that the elastic member 5 can maintain the stability of the end abutment during the movement of the limiting portion 4.

[0044] For the setting of the limiting portion 4, preferably, any limiting portion 4 includes a head portion 42 and a blocking portion 43. The head portion 42 penetrates through the second end portion 112 of the mounting hole 11, and the outer diameter of the blocking portion 43 is larger than the inner diameter of the second end portion 112, so as to form a structure in which the blocking portion 43 abuts against the inner wall of the mounting hole 11.

[0045] In this embodiment, those skilled in the art provide that the limiting portion 4 includes a head portion 42 and a blocking portion 43. Generally, the head portion 42 penetrates through the second end portion 112 of the mounting hole 11, and the blocking portion 43 abuts against the inner wall of the second end portion 112, thereby forming a structure for limiting the position where the limiting portion 4 penetrates through the mounting hole 11.

[0046] That is, the end of the elastic member 5 facing the limiting portion 4 abuts against the limiting portion 4, and the elastic force of 5 pushes the limiting portion 4 outward toward the outside of the mounting hole 11, so that the blocking portion 43 of the limiting portion 4 abuts against the inner wall of the second end portion 112, thereby completing the positioning of the position of the limiting portion 4.

[0047] With the above structure, by providing the blocking portion 43 and the head portion 42, the relative position of the limiting portion 4 can be effectively restricted, making the movement of the limiting portion 4 more stable.

[0048] In one embodiment, those skilled in the art can group multiple limiting portions 4. For example, the limiting portions 4 on both sides of the middle axis closest to the base 1 are the first limiting portion group. The direction toward the middle axis can be set as inward, and the direction away from the middle axis can be set as outward. That is, a second limiting portion group is provided outside the first limiting portion group. It can be understood that the distances of all the limiting portions 4 in the second limiting portion group from the middle axis are equal. By analogy with the foregoing settings, multiple limiting portion groups can be provided on both sides of the middle axis.

[0049] With the above structure, when positioning cylinders 2 of various sizes, the relative position of the cylinder 2 can be fixed by matching different limiting portion groups. At the same time, after positioning, the cylinder 2 can be placed in the center, and the origin of the part coordinate system remains unchanged, reducing the tool setting time and the labor intensity of the operator. Preferably, the symmetry axis of the side wall of the cylinder 2 facing the base 1 and the middle axis of the base 1 are in the same plane, thereby ensuring accurate centering placement of the cylinder 2.

[0050] In an alternative embodiment, preferably, the distances between the mounting holes 11 on either side of the middle axis and the adjacent mounting holes 11 are equal. That is, the multiple mounting holes 11 on either side of the middle axis are evenly arranged, and thus can accommodate the fixation of cylinders 2 of more sizes.

[0051] Although different specific embodiments are mentioned in the content of this application, this application is not limited to the situations described by industry standards or embodiments. Some industry standards or implementation methods slightly modified on the basis of the implementation described by custom methods or embodiments can also achieve the same, equivalent or similar, or predictable implementation effects after deformation as the above embodiments. The embodiments of data acquisition, processing, output, judgment methods, etc. using these modifications or deformations still fall within the scope of the optional implementation methods of this application.

[0052] Although this application is depicted through embodiments, those of ordinary skill in the art know that this application has many deformations and changes without departing from the spirit of this application. It is hoped that the appended embodiments include these deformations and changes without departing from this application.
