The upper lifting cylinder is mounted on a fixed base plate, and the oil seal fixing block is mounted on the rod of the upper lifting cylinder to support and fix the oil seal. The oil seal is placed on the oil seal fixing block.

[0012] In a preferred embodiment of this utility model, the cylinder push-pull plate is disposed between the upper and lower cylinder mounting plates and the linear bearing mounting plate, and the outer bushing fixing plate is disposed below the linear bearing mounting plate.

The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] This utility model relates to a preferred embodiment of an oil seal sleeve spring collet mechanism.

[0025] Please see Figure 1 The oil seal sleeve spring collet mechanism includes a fixing component, and a push-down component and an up-top component disposed on the fixing component. The push-down component is configured to drive the spring collet 9 holding the oil seal spring 11 to move downward, and the up-top component is configured to drive the oil seal fixing block 13 carrying the oil seal 14 to move upward, so as to realize that the oil seal spring 11 is quickly pressed into the inner groove of the oil seal 14.

[0026] Specifically, the first component is the fixing assembly, which includes a fixed base plate 15 and a side fixing plate 1. The fixed base plate 15 serves as the supporting foundation for the entire mechanism, and the side fixing plate 1 is vertically mounted on the fixed base plate 15, providing mounting positions for other mounting plates.

[0027] The side fixing plate 1 is connected to the upper and lower cylinder mounting plates 2, the linear bearing mounting plate 7 and the outer bushing fixing plate 8. A cylinder push-pull plate 4 is provided between the upper and lower cylinder mounting plates 2 and the linear bearing mounting plate 7. The outer bushing fixing plate 8 is located below the linear bearing mounting plate 7.

[0028] Secondly, there is a push-down assembly, which includes: upper and lower cylinders 3, cylinder push-pull plate 4, linear bearing 6, outer bushing 10 and spring collet 9. This push-down assembly can drive the spring collet 9 to move downward.

[0029] More specifically, upper and lower cylinders 3 are mounted on the upper surface of the upper and lower cylinder mounting plate 2, the output shaft of the upper and lower cylinders 3 is connected to the center of the cylinder push-pull plate 4, guide shafts 5 are provided at both ends of the cylinder push-pull plate 4, and linear bearings 6 are mounted at both ends of the linear bearing mounting plate 7.

[0030] Furthermore, one end of the guide shaft 5 is connected to the cylinder push-pull plate 4, and the other end of the guide shaft 5 passes through the linear bearing 6 and the linear bearing mounting plate 7 in sequence and is connected to the outer bushing fixing plate 8. The outer bushing 10 is installed on the outer bushing fixing plate 8. The guide shaft 5 plays a guiding role through the linear bearing 6, and the smooth movement and movement accuracy of the cylinder push-pull plate 4 are ensured by the guide shaft 5.

[0031] The spring collet 9 is used to hold the oil seal spring 11. The top of the spring collet 9 is connected to the bottom of the linear bearing mounting plate 7, and the bottom of the spring collet 9 passes through the outer bushing 10. The spring collet 9 and the outer bushing 10 are coaxial, which improves the machining accuracy and enhances the transmission efficiency. The oil seal spring 11 is fitted on the outer ring of the outer bushing 10 so that it can be firmly clamped by the spring collet 9.

[0032] In addition, there is an upper lifting assembly, which includes an upper lifting cylinder 12 and an oil seal fixing block 13, which can drive the oil seal 14 to move upward.

[0033] More specifically, the upper cylinder 12 is mounted on the fixed base plate 15, and the oil seal fixing block 13 is mounted on the rod of the upper cylinder 12 to support and fix the oil seal 14. The oil seal 14 is placed on the oil seal fixing block 13, and the oil seal 14 moves up and down through the lifting action of the upper cylinder 12.

[0034] Through the cooperation of the above components, the oil seal sleeve spring chuck mechanism can realize the automatic clamping, lifting and fixing of the oil seal, thereby improving the efficiency and accuracy of oil seal installation.

[0035] The operating process of this utility model oil seal sleeve spring collet mechanism is as follows:

[0036] In the initial state, the oil seal spring 11 is manually placed on the outer bushing 10 of the spring collet 9, and the oil seal 14 is placed on the oil seal fixing block 13;

[0037] When the start button is pressed, the upper cylinder 12 begins to work. The piston rod of the upper cylinder 12 extends and pushes the oil seal fixing block 13 and the oil seal 14 connected to it to rise to a certain height, so that the oil seal spring 11 is partially inserted into the inner groove of the oil seal 14. The purpose is to lift the oil seal 14 to a predetermined position so that subsequent assembly operations can be carried out smoothly.

[0038] The output shaft of the upper and lower cylinders 3 extends downward, causing the cylinder push-pull plate 4 to descend. The descent of the cylinder push-pull plate 4 further causes the guide shaft 5, the outer bushing fixing plate 8, and the outer bushing 10 to press down as a whole. During this action, the outer bushing 10 gradually approaches the oil seal, pushing the oil seal spring 11 into the inner groove of the oil seal 14.

[0039] Just as the oil seal spring 11 is about to be pressed into the inner groove of the oil seal 14, the spring collet 9 will extend and retract. The extension and retraction of the spring collet 9 increases the gap in the inner wall of the oil seal 14, providing the necessary space for the oil seal spring 11 to be pressed into the inner side of the oil seal 14 smoothly.

[0040] The beneficial effects of this utility model oil seal sleeve spring collet mechanism are:

[0041] It can achieve stable and rapid fixing and assembly, and efficiently insert the oil seal spring into the oil seal;

[0042] Compared with traditional manual assembly, this structure, when used with automated equipment, achieves a threefold increase in production efficiency, shortens the production cycle, and significantly increases output per unit time.

[0043] It eliminates the need for extensive manual labor, reducing labor costs while accelerating production and avoiding errors and waste caused by manual operation.

[0044] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
