Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub painting, in particular to a fixing bracket for brake wheel hub painting. Background Technique

[0002] Wheel hub painting is a method to beautify and protect the surface of the wheel hub, which can make the wheel hub look more fashionable and personalized. When carrying out wheel hub painting, it is necessary to pay attention to selecting suitable painting products and tools, following the operation specifications, and ensuring safe operation. Therefore, a fixing bracket is needed to assist in spraying when carrying out wheel hub painting.

[0003] The traditional fixing bracket for brake wheel hub painting is not stable enough when fixing the wheel hub, which is likely to cause the wheel hub to slip. Moreover, the center point positions are different after fixing wheel hubs of different sizes, so that the painting device needs to adjust the painting according to the offset position of the wheel hub center point.

[0004] Therefore, the technical personnel in this field provide a fixing bracket for brake wheel hub painting to solve the problems put forward in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art, and a fixing bracket for brake wheel hub painting is proposed. When fixing the wheel hub, the device drives the thread sleeves on both sides to move by rotating the double-headed threaded lead screw. The thread sleeves drive the two clamping blocks to move, so as to realize the clamping and fixing of the wheel hub. The middle parts of the two clamping blocks are in an open shape, with more contact points, which can clamp more firmly, and it can ensure that the center points of wheel hubs with different diameters are in the same position after being fixed, so as to facilitate the later painting device to carry out painting.

[0006] To achieve the above purpose, the utility model provides the following technical scheme:

[0007] A fixing bracket for brake wheel hub painting, including a clamping box and an installation cylinder. A double-headed threaded lead screw is rotatably arranged inside the clamping box. Thread sleeves are sleeved on both sides of the double-headed threaded lead screw. Moving plates are fixedly arranged at the tops of the two thread sleeves. Clamping blocks are fixedly arranged on the opposite sides of the tops of the moving plates. A control box is fixedly arranged on one side of the clamping box. A driven bevel gear is rotatably arranged inside the control box. The driven bevel gear is fixedly connected with the double-headed threaded lead screw. A driving bevel gear is rotatably arranged at the front end of the control box. The driving bevel gear is meshed with the driven bevel gear. A control wheel is fixedly arranged on the front end face of the driving bevel gear.

[0008] Through the above technical solution, when fixing, the rotation of the control wheel can drive the double-headed threaded lead screw to rotate, drive the clamping blocks on both sides to move inward simultaneously, and clamp and fix the hub. The opposite sides of the clamping blocks on both sides are designed with openings, which can increase the contact points, making it more stable. Moreover, the control of the double-headed threaded lead screw can ensure that the center points of different hubs are in the same position after fixation, facilitating the painting device to spray paint.

A rotating block is sleeved at the bottom of the fixed shaft. Adjusting bolts are threadedly sleeved on both sides of the front end face of the rotating block.

[0010] Through the above technical solution, the extension plates and the rotating block are connected by the fixed shaft. The position above the extension plates can be tilted at an angle around the fixed shaft and is supported by the adjusting bolts on both sides, so that the inclination angle of the hub can be adjusted by controlling the two bolts.

[0011] Further, a linear bearing is fixedly arranged at the top end of the installation cylinder. A rotating shaft is fixedly arranged in the middle of the bottom end of the rotating block. The rotating shaft is rotatably connected with the linear bearing.

[0012] Through the above technical solution, the connection between the linear bearing and the rotating shaft enables the top of the bracket to rotate, facilitating the adjustment of the direction of the inclination of the hub.

[0013] Further, a top cover is fixedly arranged at the top of the clamping box.

[0014] Through the above technical solution, the top cover can not only block the paint for spraying the hub but also block dust, preventing impurities from eroding the lead screw.

[0015] Further, a bottom plate is fixedly arranged at the bottom of the installation cylinder.

[0016] Through the above technical solution, the bottom plate increases the grounding area, thereby preventing the bracket from tipping over after fixing the hub.

[0017] Further, anti-slip rubber sheets are fixedly arranged on the opposite sides of the two clamping blocks.

[0018] Through the above technical solution, the anti-slip rubber sheets can increase the friction at the contact points, making it more stable.
