Description

Technical Field

[0001] This utility model relates to the field of spraying tooling technology, and more specifically, to a manual spray gun positioning tooling. Background Technology

[0002] Automotive wheel hub bearings are composed of two sets of tapered roller bearings or ball bearings. The installation, lubrication, sealing, and clearance adjustment of the bearings are all carried out on the automobile production line. This structure makes assembly difficult, costly, and unreliable at the automobile manufacturing plant. Moreover, when the car is maintained at a repair shop, the bearings also need to be cleaned, lubricated, and adjusted.

[0003] Because wheel hub bearings are very close to the ground and high-temperature components such as brake discs, they need to adapt to various complex road conditions and harsh driving environments. Therefore, the bearing seals must have good grease-leakage prevention performance, as well as good heat resistance, mud and sewage resistance.

[0004] Wear or damage to wheel bearings or wheel units can cause undesirable and costly failures while the vehicle is in motion, and may even pose a safety hazard.

[0005] Therefore, controlling the film thickness of wheel hub bearings has become a very important matter. The film thickness affects the corrosion resistance of wheel hub bearings and plays a decisive role in the service life of later installation and replacement.

[0006] In existing technologies, when using handheld sprayers to coat ring-shaped workpieces such as wheel hub bearings, the spraying distance angle and spraying time are difficult to control, resulting in uncontrollable film thickness data. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] Example 1:

[0030] like Figure 1As shown, this application provides a manual spray gun positioning fixture, including a base 1; a support rod 2 is connected to the upper part of the base 1, a slider 3 is slidably sleeved on the support rod 2, and a first fastening bolt 4 for fixing the slider 3 to the support rod 2 is provided on the side of the slider 3; a connecting plate 5 is provided on the side of the slider 3, and a transverse support rod 6 is provided on one side of the connecting plate 5. In order to adjust the height, the slider 3 can slide vertically on the support rod 2, and the slider 3 is fixed to a suitable height by tightening the first fastening bolt 4.

[0031] like Figure 4 As shown, the end of the horizontal support rod 6 passes through the rotating mounting base 7 and is rotatably connected to the rotating mounting base 7 via the rotating joint 13. In order to adjust the vertical angle during spraying, the horizontal support rod 6 rotates in the rotating mounting base 7 in the horizontal direction, thereby adjusting the vertical angle during spraying.

[0032] like Figure 2 and Figure 3 As shown, a semi-circular sliding groove 12 is provided on the connecting plate 5. A limit rod 10 is slidably installed in the sliding groove 12. The top of the limit rod 10 is connected to the spray gun fixing block 9. A positioning groove 11 is provided on the spray gun fixing block 9. When the limit rod 10 slides in the positioning groove 11, the left and right angles of the spray gun fixing block 9 can be adjusted.

[0033] Furthermore, the spray gun fixing block 9 is movably installed on the top or front of the sliding groove 12, and the opening of the sliding groove 12 is set away from the spray gun fixing block 9. In this embodiment, the spray gun fixing block 9 is movably installed. When the spray gun fixing block 9 is rotated, the limiting rod 10 and the inner wall of the sliding groove 12 are tightly fitted to ensure sufficient friction. Alternatively, the limiting rod 10 can be a prism to ensure that the position of the spray gun fixing block 9 is stable and not easy to shake after the position is adjusted.

[0034] Example 2:

[0035] like Figure 6 and Figure 7 As shown, the difference from the above embodiment is that the bottom of the spray gun fixing block 9 is provided with a rotating shaft 14; the connecting plate 5 is provided with a connecting hole 15 coaxial with the sliding groove 12. The spray gun fixing block 9 is rotatably installed on the top of the sliding groove 12 through the rotating shaft 14, and the opening surface of the sliding groove 12 is set away from the spray gun fixing block 9. In this embodiment, the position of the spray gun fixing block 9 is fixed but can be rotated. When rotating, the limiting rod 10 also moves in the sliding groove 12 to adjust the angle. Similarly, a rubber sleeve can be added to the outer wall of the rotating shaft 14 at the bottom of the spray gun fixing block 9 to obtain sufficient friction with the connecting hole 15 to ensure that the position of the spray gun fixing block 9 is stable and not easy to shake.

[0036] It should be noted that the tooling in this application is used in conjunction with a rotating platform, and the spraying time is controlled by a time relay. In contrast, in this application, when the existing spray gun is installed in the spray gun fixing block 9, hand-held spraying is required.

[0037] Based on the above embodiments, such as Figure 3 and Figure 6 As shown, the edge of the connecting plate 5 on the opposite side of the sliding groove 12 is chamfered.

[0038] Based on the above embodiments, such as Figure 5 As shown, both the support rod 2 and the slider 3 are rectangular aluminum profile tubing to prevent the slider 3 from rotating around the support rod 2.

[0039] Based on the above embodiments, such as Figure 2 and Figure 7 As shown, the positioning groove 11 extends through both the upper and lower ends of the spray gun fixing block 9. The positioning groove 11 includes a first mounting groove and a second mounting groove arranged sequentially from top to bottom. The bottom of the inner wall of the first mounting groove is horizontally arranged, and the connection between the first mounting groove and the second mounting groove is smoothly transitioned. The inner wall of the second mounting groove gradually slopes towards the front end face of the spray gun fixing block 9 from top to bottom. This structure is based on the existing handheld spray gun handle structure. The first mounting groove corresponds to the anti-pinch block of the spray gun handle, and the second mounting groove corresponds to the end of the handle. During spraying, the handheld spray gun is pressed and placed in the spray gun fixing block 9. After adjusting the angle, the workpiece is rotated to drive the car wheel hub bearing to rotate for spraying.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
