[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme of the embodiments of the utility model will be clearly and completely described in conjunction with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0027] As Figure 1 The device for quickly assembling a guide bushing comprises a pressing machine 1, a pressing rod 2, a bushing 3, a guide 4 and a positioning sleeve 5.

[0028] Specifically, the guide 4 is an axisymmetric structure and has a through central hole along a central axis, a middle section of the central hole is a bushing mounting hole for mounting the bushing, and the central hole has the smallest size at the position. The upper part of the bushing mounting hole has a positioning sleeve mounting hole for mounting the positioning sleeve 5, the positioning sleeve 5 is an annular structure, and the outer wall of the positioning sleeve 5 is in clearance fit with the positioning sleeve mounting hole. The height of the positioning sleeve 5 is greater than the distance between the step surface of the positioning sleeve mounting hole and the top surface of the guide 4, that is, the height of the positioning sleeve 5 can make the positioning sleeve 5 protrude from the top surface of the guide 4, thereby facilitating taking and placing.

[0029] The inner diameter of the positioning sleeve 5 is slightly greater than the outer diameter of the bushing 3, so that the bushing 3 can move downward from the positioning sleeve 5, and the bushing 3 can be well fixed in the inner hole of the positioning sleeve 5.

[0030] The positioning sleeve 5 can limit the moving path of the bushing 3 in the embodiment, and is used in combination with the pressing rod 2, so that the bushing 3 is loaded into the bushing mounting hole of the guide 4 along a substantially vertical direction.

[0031] The positioning sleeve 5 in the embodiment can be replaced according to different sizes of the bushing 3 and the guide 4, but needs to meet the above requirements.

[0032] The pressing rod 2 is a cylindrical structure, and the bottom of the pressing rod 2 comprises a limiting structure for mounting the bushing 3. In the embodiment, the limiting structure is a step-shaped structure formed by removing the annular structure on the outer wall of the bottom of the pressing rod 2, so as to form a reduced diameter. The outer diameter of the step-shaped structure is slightly smaller than the inner diameter of the bushing 3, and the step-shaped structure is sleeved in the inner hole of the bushing 3, thereby playing a limiting and fixing role. The engagement of the bushing 3 and the step-shaped structure means that the step surface of the step-shaped structure is attached to the top surface of the bushing 3, thereby facilitating uniform stress. The height of the step-shaped structure is not limited, and is preferably greater than 0.5 times the height of the bushing 3, so as to better support the bushing 3. The upper part of the outer circle step-shaped structure of the upper end of the pressing rod 2 has a diameter slightly smaller than the inner hole of the positioning sleeve 5, so that the outer circle of the pressing rod 2 does not touch the inner hole of the positioning sleeve 5 during the pressing process of the bushing.

[0033] The press 1 is a manual press, comprising an upper press head 11 and a lower base plate 12. The bottom surface of the press head 11 is connected to a press rod 2, and the top surface of the press rod 2 is in planar contact with the bottom surface of the press head 11. Meanwhile, the press rod 2 can be replaced to adapt to different sizes of the shaft sleeve 3 and the guide 4.

[0034] Working process of the embodiment:

[0035] The guide 4 is placed on the base plate 12 of the manual press, the positioning sleeve 5 is placed in the positioning sleeve mounting hole of the guide 4, and the shaft sleeve 3 is placed in the inner hole of the positioning sleeve 5. The shaft sleeve 3 is pressed manually to ensure that it is inserted to about half of the position, and then the press rod 2 is sleeved into the shaft sleeve 3. The whole workpiece is placed directly below the press head 11 of the manual press, and the press rod 2 is slowly pressed down until the shaft sleeve 3 is completely sleeved into the guide 4. Then the press rod 2 and the positioning sleeve 5 are removed, and the installation is completed.

[0036] The device in the embodiment has simple structure, convenient use and strong universality. Different models of the shaft sleeve 3 can be quickly replaced to improve the efficiency. The press head 11 is made of pure copper to protect the shaft sleeve 3 from being damaged. The bottom of the press rod 2 has a guide and positioning structure to ensure the accuracy of the shaft sleeve 3 during the pressing and assembling.

[0037] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalent ones. These modifications or replacements do not change the essence of the corresponding technical solutions, and do not deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
