Abstract
Description
Technical Field
[0001] This utility model relates to the field of workpiece coating technology, specifically to a thermal grease coating fixture. Background Technology
[0002] Many devices currently rely on bearings for heat transfer. These devices typically operate in high-temperature, high-speed, or high-load environments. The bearings in these devices not only need to reduce friction and support rotating parts, but also need to effectively transfer or dissipate heat to prevent overheating and damage; examples include turbines.
[0003] However, after the inner shaft and outer seat are installed with the bearing, there will be a slight gap between the two contact surfaces, which will reduce the thermal conductivity, increase the thermal resistance, and hinder heat conduction. Therefore, it is necessary to fill the two contact surfaces with thermal grease to reduce the thermal resistance of the inner and outer contact surfaces, improve the thermal conductivity, and conduct heat better.
[0004] Because thermal grease is a paste-like substance, it is viscous and difficult to spread evenly. When applied manually, due to individual differences in feel and pressure, it is impossible to apply the thermal grease evenly to the two cylindrical surfaces. In addition, manual application also suffers from poor operation quality, low work efficiency, and high labor costs. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0027] Example 1
[0028] Reference Figure 1 A thermal grease application fixture includes a worktable 1, and a lead screw module 1 2, a lead screw module 2 3, a motor mounting bracket 4, a motor 5, a coupling 6, a felt mounting bracket 7, a felt applicator 8, and a positioning post 10 mounted on the worktable 1. It should be noted that the worktable 1 is a rectangular plate structure with a matrix array of fixing holes, wherein the lead screw module 1 2 and the workpiece to be tested are both fixed on the worktable 1 through the fixing holes.
[0029] Reference Figure 1 The lead screw module 12 is horizontally mounted on the worktable 1, and can adjust the coating position horizontally according to the position of the workpiece to be tested. The lead screw module 12 is threadedly connected to the module slide 1201, which can move horizontally along the lead screw module 12. The lead screw module 23 is mounted on the module slide 1201, which can drive the lead screw module 23 to move horizontally.
[0030] Reference Figure 1 The second lead screw module 3 is threadedly connected to the second module slide 301, which can move vertically along the second lead screw module 3. On one side of the second module slide 301, a motor mounting bracket 4 is detachably connected by bolts or pins. A motor 5 is mounted on the motor mounting bracket 4. The output end of the motor 5 faces the worktable 1. The output end of the motor 5 is connected to a wool felt mounting bracket 7 through a coupling 6. Wool felt sticks 8 are detachably connected to the bottom sides of the wool felt mounting bracket 7 facing the worktable 1 through bolts or pins.
[0031] In this embodiment 1, the workpiece to be coated is a circular bearing outer seat 9. The bearing outer seat 9 is fixed in the fixing hole on the worktable 1 by the positioning pin 10. The two wool felt applicator sticks 8 can be adjusted to contact the inner ring of the bearing outer seat 9. When the motor 5 drives the wool felt fixing frame 7 to rotate through the coupling, it can drive the two wool felt applicator sticks 8 to rotate in the inner ring of the bearing outer seat 9. When rotating, the two wool felt applicator sticks 8 fully contact the inner ring of the bearing outer seat 9 to achieve the application of thermal conductive silicone grease to the bearing outer seat 9.
[0032] In use, the bearing outer seat 9 is placed on the workbench, and multiple positioning pins 10 are inserted into the fixing holes of the workbench to fix the bearing outer seat 9 so that it cannot wobble. Then, the horizontal position of the wool felt applicator 8 is adjusted by the lead screw module 1 2 so that it is directly above the bearing outer seat 9. Then, the wool felt applicator 8 is adjusted by the lead screw module 2 3 to be placed vertically downward on the inner side of the bearing outer seat 9. At this time, the two wool felt applicator 8 are in close contact with the inner side of the bearing outer seat 9 and the surface to be coated. The motor above the wool felt applicator 8 rotates, which will drive the wool felt fixing frame 7 to rotate. The wool felt applicator 8 located at both ends of the wool felt fixing frame 7 will rotate accordingly. The thermal grease on the wool felt applicator 8 will be attached to the inner side of the bearing outer seat 9 as the wool felt applicator rotates.
[0033] Example 2
[0034] Reference Figure 2 The rest is the same as above. The difference from Example 1 is that the workpiece to be coated in Example 2 is the inner shaft 12 of the bearing, wherein the diameter of the inner shaft 12 is smaller than the diameter of the outer bearing seat 9. The distance between the two wool felt applicators 8 can also be adjusted according to the actual size of the inner shaft 12 to ensure that the wool felt applicators 8 can contact the workpiece to be coated. The wool felt applicators 8 need to apply thermal conductive silicone grease to the outer ring of the inner shaft 12. Therefore, the inner side of the inner shaft 12 is fixed with positioning pins 10. Then, the two wool felt applicators 8 contact the outer ring of the inner shaft 12 and apply it evenly when rotating.
[0035] Example 3
[0036] Reference Figure 3 The rest is the same as above, except that the two wool felt applicators 8 can be replaced with a wool felt brush 11. The wool felt brush 11 contacts the inner ring of the bearing outer seat 9 on both sides. The wool felt brush 11 is located directly below the wool felt fixing bracket 7. Thermal grease is applied to both ends of the wool felt brush 11, and it can apply thermal grease to the inner ring of the bearing outer seat 9 when rotating. As the wool felt brush 11 rotates, the thermal grease on the wool felt brush 11 will adhere to the inner side of the bearing outer seat 9.
[0037] Example 4
[0038] Reference Figure 4 The rest is the same as in Example 3. The difference from Example 3 is that the workpiece to be coated in Example 4 is a plate-shaped workpiece 13, and the bottom of the wool felt brush 11 is coated with thermal conductive silicone grease. The bottom of the wool felt brush 11 contacts the coating surface of the plate-shaped workpiece 13 under the drive of the lead screw module 2 3, and then moves horizontally through the lead screw module 1 2 to achieve coating of the plate-shaped workpiece 13.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
