[0008] The pushing and returning mechanism includes a pressing head. The pressing head slides in the guiding fixed sleeve through a wear-resistant sleeve, and the rotating part is pushed to slide along the guiding fixed sleeve by the pressing head.

[0009] The technical effect of adopting the above technical solution is as follows: The operator first uses the positioning mechanism to fix the position of the bushing installation tooling, places the rotating part, such as a bushing or a shaft sleeve, in the guiding fixed sleeve. By pressing the pressing head with a pressing rod (the pressing rod is generally arranged on a press), the pressing head slides in the guiding fixed sleeve, thereby pushing the rotating part to slide along the guiding fixed sleeve, and then pressing the rotating part into the hole to be installed. Through the methods of guiding, positioning, and fixing, the automatic installation of parts such as bearings and bushings is realized, and at the same time, the installation surface of the parts will not be damaged, ensuring the installation accuracy.

[0010] Further, the pushing and returning mechanism further includes a spring fixed ring located on one side of the pressing head, and a spring moving side fixed ring is provided on the other side of the pressing head. The spring fixed ring is installed on the guiding fixed sleeve through bolts, and the spring moving side fixed ring is connected to the pressing head, so that the spring moving side fixed ring slides synchronously with the pressing head. A spring is connected between the spring moving side fixed ring and the spring fixed ring. After the rotary part is press-fitted, the spring is used to reset the pressing head.

[0011] The technical effect of adopting the above technical solution is that by connecting the spring fixed ring and the spring moving side fixed ring with a spring, and the spring moving side fixed ring is connected to the pressing head. After the press-fitting is completed, the spring can pull the pressing head back to the starting position, that is, automatically reset the pressing head, which is convenient for the next use, improves the convenience of using the pressing head, and does not require manual adjustment of the initial position of the pressing head repeatedly.

[0012] Further, both ends of the spring are respectively connected to the spring moving side fixed ring and the spring fixed ring through pull rings.

[0013] The technical effect of adopting the above technical solution is that after long-term use, if the spring is deformed, the operator can easily disassemble and replace the spring by disassembling the pull ring.

[0014] Further, a plurality of springs are provided, and the plurality of springs are evenly arranged along the circumference of the spring fixed ring.

[0015] The technical effect of adopting the above technical solution is that the setting of a plurality of springs further improves the stability of the pressing head reset, and if one spring is damaged, the other springs can still reset the pressing head.

[0016] Further, a guiding portion is provided on the side of the spring moving side fixed ring close to the pressing head, and the end of the spring is placed on the guiding portion. The guiding portion is used to guide the expansion and contraction of the spring.

[0017] The technical effect of adopting the above technical solution is that during the expansion and contraction of the spring, the spring is guided by the guiding portion, which further improves the stability of the spring during the expansion and contraction process.

[0018] Further, a limiting portion is provided on the side of the pressing head close to the spring fixed ring, and the limiting portion is conical.

[0019] The technical effect of adopting the above technical solution is that when the pressing rod applies pressure to the pressing head, the setting of the limiting portion can prevent the force from being skewed and affect the press-fitting effect.

[0020] Further, the positioning portion includes a first positioning plate and a second positioning plate. The first positioning plate is used for horizontally positioning the guiding fixed sleeve, and the second positioning plate is used for vertically positioning the guiding fixed sleeve.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The principles and features of the present invention will be described below in conjunction with all the drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0032] An embodiment of the present invention discloses a bearing shell installation tooling.

[0033] Refer to Figures 1-8, a bearing bush installation tooling, comprising a positioning mechanism and a pushing and returning mechanism. The positioning mechanism includes a guiding fixed sleeve 8 and a positioning part for positioning the guiding fixed sleeve 8. The positioning part includes a first positioning plate 2 and a second positioning plate 3. The first positioning plate 2 is used for horizontally positioning the guiding fixed sleeve 8 to position the guiding fixed sleeve 8 in the horizontal direction, and the second positioning plate 3 is used for vertically positioning the guiding fixed sleeve 8. The limiting of the guiding fixed sleeve 8 is realized through the first positioning plate 2 and the second positioning plate 3. Among them, the first positioning plate 2 and the second positioning plate 3 can be connected to the guiding fixed sleeve 8 through bolts.

[0034] The positioning mechanism further includes a locking mechanism 4, which is also used for limiting the tooling. The purpose of fixing the tooling to the cylinder head is realized through the combined action of the first positioning plate 2, the second positioning plate 3 and the locking mechanism 4, and the positioning purpose of the tooling is realized, that is, the quick clamp locks the tooling and the cylinder head. The locking mechanism 4 enables the contact surface 15 (the end face close to the quick clamp) of the guiding fixed sleeve 8 to lean against the body to be installed (i.e., the cylinder head). Through the combined action, the whole tooling is relatively positioned and fixed with the cylinder head, so as to facilitate the subsequent pressing operation. The locking mechanism 4 is connected to the second positioning plate 3. The locking mechanism 4 is a quick clamp and can also be other forms of locking mechanisms 4.

[0035] The pushing and returning mechanism includes a pressure head 10, which is of a cylindrical structure. The pressure head 10 slides in the guiding fixed sleeve 8 through a wear-resistant sleeve 5. The rotary part 11 is placed in the guiding fixed sleeve 8. The pressure head 10 is used to push the rotary part 11 to slide along the guiding fixed sleeve 8. The pressure rod 1 is used to drive the pressure head 10. The pressure rod 1 is generally arranged on a press and is used to provide pressure to the pressure head 10. Through the sliding of the pressure head 10, the rotary part 11 is pressed into the hole to be installed. Through the methods of guiding, positioning and fixing, the automatic installation of bearing and bearing bush parts is realized, and the installation surface of the parts will not be damaged, ensuring the installation accuracy. The pressure rod 1 and the pressure head 10 are of a split design, that is, there is no connection relationship between the pressure rod 1 and the pressure head 10. Only the pressure rod 1 is used to drive the pressure head 10 to slide. Such a design can facilitate the movement or replacement of the entire installation tooling, improving the convenience of use.

[0036] A limiting part 6 is arranged on the side of the pressure head 10 in contact with the pressure rod 1. The limiting part 6 is conical. As Figure 5 shown, the limiting part 6 is located at the middle position of the pressure head 10. When the pressure rod 1 applies pressure to the pressure head 10, the setting of the limiting part 6 can provide position guidance for the pressure rod 1 and limit it to prevent slipping and moving to the edge position of the pressure head 10, preventing the force on the pressure head 10 from being skewed and affecting the pressing effect.

[0037] The pushing and returning mechanism further includes a spring fixing ring 9 located on one side of the pressure head 10. The spring fixing ring 9 is arranged on the side of the pressure head 10 close to the limiting part 6. On the other side of the pressure head 10, there is a spring moving-side fixing ring 12. The spring fixing ring 9 is installed on the guiding fixing sleeve 8 through bolts. The spring moving-side fixing ring 12 is connected to the pressure head 10, so that the spring moving-side fixing ring 12 slides synchronously with the pressure head 10, as Figure 5 shown; through holes for the spring 13 to pass through are formed in the edge of the pressure head 10. The spring moving-side fixing ring 12 and the spring fixing ring 9 are connected by the spring 13. After the rotary part 11 is press-fitted, the spring 13 is used to reset the pressure head 10. After the press-fitting is completed, the pressure head 10 can be pulled back to the starting position by the spring 13, that is, the pressure head 10 is automatically reset, which is convenient for the next use and improves the convenience of using the pressure head 10 without the need for manual repeated adjustment of the initial position of the pressure head 10. Among them, the moving distance of the pressure head 10 is determined by the stroke of the pressure rod 1, which is determined by the pressure rod 1 in the forward direction (the direction of pushing the rotary part). When resetting, the spring fixing ring 9 can limit the pressure head 10 to prevent the pressure head 10 from sliding out of the guiding fixing 8.

[0038] Fixing blocks 7 are arranged on both the spring moving-side fixing ring 12 and the spring fixing ring 9. The two ends of the spring 13 are respectively connected to the fixing blocks 7 of the spring moving-side fixing ring 12 and the spring fixing ring 9 through pull rings 14, as Figure 1 and Figure 4 shown. After long-term use, if the spring 13 is deformed, the operator can easily disassemble the spring 13 for replacement by disassembling the pull ring 14.

[0039] A plurality of springs 13 are provided, and the plurality of springs 13 are evenly arranged along the circumferential direction of the spring fixing ring 9. In the embodiment of the present utility model, three springs 13 are provided, and the three springs 13 are evenly distributed along the circumferential direction of the spring fixing ring 9 / the spring moving-side fixing ring 12. The arrangement of the plurality of springs 13 further improves the stability of the reset of the pressure head 10, and if one spring 13 is damaged, the other springs 13 can still reset the pressure head 10.

[0040] A guiding part 16 is arranged on the side of the spring moving-side fixing ring 12 close to the pressure head 10. The number and position of the guiding parts 16 correspond to the number and position of the springs 13 one by one, that is, three guiding parts 16 are provided. The ends of the springs 13 are placed on the guiding parts 16, and the guiding parts 16 are used to guide the expansion and contraction of the springs 13. During the expansion and contraction of the springs 13, the guiding parts 16 guide the springs 13, further improving the stability of the expansion and contraction process of the springs 13.

[0041] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
