Description

Technical Field

[0001] This invention relates to the field of turntable technology, and more specifically to a turntable oil seal installation device. Background Technology

[0002] To improve the waterproof and dustproof performance of the gimbal, an oil seal needs to be installed between the horizontal axis and the bushing of the gimbal during assembly. Current installation procedures often rely on manual assembly, which can lead to uneven pressing force, causing the oil seal to tilt or deform. This affects the gimbal's friction, airtightness, and operational accuracy. Summary of the Invention

[0003] In order to overcome the shortcomings of the above technologies, this utility model provides a turntable oil seal installation device that enables the oil seal to be assembled in one go and improves the assembly accuracy.

[0004] The technical solution adopted by this utility model to overcome its technical problem is:

[0005] A turntable oil seal mounting device includes a turntable bushing and a horizontal shaft rotatably mounted within the turntable bushing via bearings, and further includes:

[0006] The support is fixed to the rear end of the turntable bushing via a connecting mechanism;

[0007] The lead screw is fixed to the support by a fixing mechanism, and the lead screw is coaxial with the horizontal axis;

[0008] The pressure plate, in a circular structure, is fitted onto the support, and its outer end face contacts the oil seal; and

[0009] The pressure plate drive mechanism is connected to the lead screw drive, and the pressure plate drive mechanism drives the pressure plate to move back and forth along the horizontal axis.

[0010] The aforementioned connecting mechanism includes N countersunk holes spaced apart on the support 3 along the circumferential direction and N screw holes correspondingly located at the rear end of the turntable bushing. The screws pass through the countersunk holes and are screwed into the screw holes.

[0011] Furthermore, the aforementioned fixing mechanism includes nuts respectively disposed on the inner and outer sides of the support, a lead screw inserted into the support, and nuts screwed onto the lead screw.

[0012] Furthermore, the aforementioned pressure plate drive mechanism includes a slide plate that is slidably inserted into the lead screw along the lead screw axis and a handwheel that is screwed onto the lead screw. The inner end of the handwheel is in contact with the outer end face of the slide plate. The outer ends of M support rods are fixed to the slide plate at intervals along the circumferential direction by bolts, and the inner ends of each support rod are fixed to the pressure plate.

[0013] To improve guidance, a guide shaft fixed to the support is also included. The guide shaft is slidably inserted into the slide plate, and the axis of the guide shaft is parallel to the axis of the horizontal axis.

[0014] Preferably, M is 3.

[0015] The beneficial effects of this utility model are as follows: the oil seal is placed in the installation area between the turntable bushing and the horizontal shaft, and then the support is fixed to the rear end of the turntable bushing through the connecting mechanism. The pressure plate is driven by the pressure plate drive mechanism to move the pressure plate inward along the axial direction of the lead screw. Since the lead screw and the horizontal shaft are coaxial, the oil seal can be smoothly pressed into place along the axial direction of the horizontal shaft. Pressing the oil seal in with the flat surface of the pressure plate can avoid the situation of the oil seal being tilted and difficult to assemble, thus improving the assembly efficiency of the turntable and ensuring that the friction, airtightness and operating accuracy of the turntable meet the standards after assembly.

[0019] The following is in conjunction with the appendix Figure 1 Appendix Figure 2 The present invention will be further described below.

[0020] A turntable oil seal mounting device includes a turntable bushing 8 and a horizontal shaft 9 rotatably mounted inside the turntable bushing 8 via a bearing 10. It also includes: a support 3 fixed to the rear end of the turntable bushing 8 via a connecting mechanism; a lead screw 2 fixed to the support 3 via a fixing mechanism, the lead screw 2 being coaxial with the horizontal shaft 9; a pressure plate 6 with a circular structure, the pressure plate 6 being fitted onto the support 3, the pressure plate 6 contacting the outer end face of the oil seal 11; and a pressure plate driving mechanism, which is connected to the lead screw 2 for transmission, the pressure plate driving mechanism driving the pressure plate 6 to move back and forth along the axial direction of the horizontal shaft 9. In use, the oil seal 11 is placed in the installation area between the turntable bushing 8 and the horizontal shaft 9. Then, the support 3 is fixed to the rear end of the turntable bushing 8 through the connecting mechanism. The pressure plate 6 is driven to move inward along the axis of the lead screw 2 through the pressure plate drive mechanism. Since the lead screw 2 and the horizontal shaft 9 are coaxial, the oil seal 11 can be smoothly pressed into place along the axis of the horizontal shaft 9. Pressing the oil seal 11 in with the flat surface of the pressure plate 6 can avoid the situation of the oil seal 11 being installed tilted and difficult to assemble, thus improving the assembly efficiency of the turntable and ensuring that the friction, airtightness and operating accuracy of the turntable meet the standards after assembly.

[0021] In one embodiment of this utility model, the connecting mechanism has the following structure: it includes N countersunk holes 13 spaced apart on the support 3 along the circumferential direction and N screw holes 14 correspondingly disposed at the rear end of the turntable bushing 8. The screws pass through the countersunk holes 13 and are screwed into the screw holes 14. The support 3 is connected and fixed to the turntable bushing 8 by screws, which facilitates connection and disassembly and improves efficiency.

[0022] In one embodiment of this utility model, the fixing mechanism has the following structure: it includes nuts 15 respectively disposed on the inner and outer sides of the support 3, a lead screw 2 inserted into the support 3, and nuts 15 screwed onto the lead screw 2. The lead screw 2 is fixed by tightening the nuts 15 arranged at the front and rear ends of the support 3, thereby achieving the clamping and fixing of the lead screw 2 onto the support 3. The installation is convenient, and loosening the nuts 15 can also easily adjust the axial position of the lead screw 2. After adjustment, the nuts 15 can be tightened.

[0023] In one embodiment of this utility model, the pressure plate driving mechanism has the following structure: a slide plate 4 slidably inserted into the lead screw 2 along the axial direction of the lead screw 2, and a handwheel 1 screwed onto the lead screw 2. The inner end of the handwheel 1 contacts the outer end face of the slide plate 4. The outer ends of M support rods 5 are fixed to the slide plate 4 at intervals along the circumferential direction by bolts 12. The inner ends of each support rod 5 are fixed to the pressure plate 6. Rotating the handwheel 1 causes it to move along the axial direction of the lead screw 2, thereby driving the slide plate 4 to slide inward. The slide plate 4 uses the support rods 5 to drive the pressure plate 6 to move inward, pressing the oil seal 11 into place. Preferably, in this embodiment, M is 3.

[0024] In one embodiment of this utility model, a guide shaft 7 fixed to the support 3 is further included. The guide shaft 7 is slidably inserted into the slide plate 4, and the axis of the guide shaft 7 is parallel to the axis of the horizontal axis 9. By setting the guide shaft 7, the guiding performance of the slide plate 4 during sliding can be improved, and the slide plate 4 can be prevented from rotating itself when moving axially.
