Technical Field
[0001] This utility model relates to the field of wheel hub technology, and in particular to an adjustable auxiliary bracket for processing wheel hubs of three-wheeled vehicles. Background Technology
[0002] Tricycles are a common mode of transportation, a combination of human-powered vehicles and bicycles. They are divided into several types, including human-powered tricycles, electric tricycles, motorized tricycles, and children's tricycles. They are mainly used for passenger transport, cargo transport, and leisure and entertainment. The wheel hub is a metal part that supports the tire as the inner contour of the tire, and its surface is generally treated with processes such as painting and electroplating.
[0003] Current adjustable tricycle wheel hub processing auxiliary brackets can only be used for fixing during drilling and cutting processes. However, they cannot cover the wheel hub surface during painting and electroplating processes. In addition, the angle of ordinary brackets is fixed and cannot be adjusted with drill bits or cutters.
[0004] Therefore, in view of the existing auxiliary brackets for processing wheel hubs of three-wheeled vehicles, which cover the surface of the wheel hub during painting and electroplating processes, and whose bracket angle is fixed, the wheel hub can be fixed by the friction between the rubber pad and the wheel hub. The rotating ring seat makes it easy to loosen the three second knobs for adjustment, which is convenient for multi-angle drilling and cutting of the wheel hub. The setting of multiple balls facilitates the rotation of the wheel hub, so as to achieve the effect of convenient all-round spraying of the wheel hub. Utility Model Content
[0005] To overcome the problem that most wheel hub processing auxiliary brackets can only be used for fixing during processing such as drilling and cutting, while they cover the wheel hub surface during painting and electroplating processes, and that the angle of ordinary brackets is fixed and cannot be adjusted with drill bits and cutters.

[0014] The beneficial effects of this utility model are:
[0015] When using the wheel hub processing auxiliary bracket, loosening the first and second knobs allows the lower and upper brackets to rotate freely. The wheel hub can be adjusted to a suitable position for the worker based on its size and the worker's height. The wheel hub is secured by the friction between the rubber pad and the wheel hub. Rotating the ring seat allows for easy loosening of the three second knobs for adjustment, facilitating multi-angle drilling and cutting of the wheel hub.

An upper support 35 is provided on the upper end of the lower support 34. A universal joint 41 is provided on the upper end face of the upper support 35. A mounting clip 42 is fixedly installed on the outer side of the universal joint 41. A limiting groove 43 is provided on the inner side of the mounting clip 42. A sliding rod 44 is provided on the inner side of the limiting groove 43. A rubber pad 45 is fixedly installed on the outer side of the sliding rod 44. A rotating groove 46 is provided on the inner side, and a ball bearing 47 is provided on the inner side of the rotating groove 46. A retaining ring 48 is provided on the outer side of the mounting clip 42. The universal ball joint 41 facilitates the overall rotation of the mounting clip 42. The two sliding rods 44 are pushed into the limiting groove 43. The retaining ring 48 is rotated to limit the sliding rods 44. The two rubber pads 45 are provided to clamp the wheel hub to prevent the wheel hub from rotating. Pulling the sliding rods 44 outward pulls the rubber pads 45 into the limiting groove 43. The multiple balls 47 are provided to rotate in the recess of the wheel hub, so that the wheel hub itself rotates, which is convenient for the wheel hub to be painted or electroplated. The universal ball joint 41, together with the support component, facilitates the multi-angle rotation of the wheel hub, making cutting and drilling more convenient.
[0023] Please see Figure 1 and Figure 2 In this embodiment, the base 1 and the ring seat 2 are slidably connected. The cross-section of the base 1 is a convex structure, and the cross-section of the ring seat 2 is an inverted concave structure. Three sets of support components are equally spaced on the upper end face of the ring seat 2. The support components include a clamping plate 31, a first screw 32, a first knob 33, a lower bracket 34, an upper bracket 35, a second screw 36, and a second knob 37. The first screw 32 is provided on the inner side of the clamping plate 31, and the first knob 33 is provided on the outer side of the first screw 32. The first knob 33 is threadedly connected to the first screw 32. The lower bracket 34 is provided on the outer side of the first screw 32, and the lower bracket 34 is rotatably connected to the first screw 32. The lower support 34 has a second screw 36 on its inner side and a second knob 37 on its outer side. The second knob 37 and the second screw 36 are threaded together. The upper support 35 is located on the outer side of the second screw 36 and is rotatably connected to the second screw 36. The upper support 35 rotates on the base 1 via the ring seat 2, which facilitates the operation of the three support components. Loosening the first knob 33 and the second knob 37 allows the lower support 34 and the upper support 35 to rotate freely. The wheel hub can be adjusted to a suitable position for the worker based on the size of the wheel hub and the height of the worker. Tightening the first knob 33 and the second knob 37 fixes the lower support 34 and the upper support 35.
[0024] Please see Figure 3 and Figure 4 In this embodiment, the universal ball joint 41 is rotatably connected to the upper bracket 35. There is one limiting groove 43 on each of the upper and lower sides of the mounting clip 42. The sliding rod 44 is slidably connected to the limiting groove 43. The length of the sliding rod 44 is less than the width of the mounting clip 42. Three sets of rotating grooves 46 are opened on the same plane as the limiting groove 43. The ball bearing 47 is rotatably connected to the rotating groove 46. The highest point of the ball bearing 47 is higher than the horizontal plane of the limiting groove 43. The retaining ring 48 is rotatably connected to the mounting clip 42. The friction between the rubber pad 45 and the hub fixes the hub, which is convenient for drilling and cutting operations. When the rubber pad 45 slides into the limiting groove 43, the ball bearing 47 contacts the groove of the hub, which is convenient for the hub to rotate and perform painting and electroplating treatment.
[0025] When working, first loosen the first knob 33 and the second knob 37 to make the lower bracket 34 rotate along the first screw 32 and the upper bracket 35 rotate along the second screw 36, so that the lower bracket 34 and the upper bracket 35 can be folded freely. Then, the wheel hub is clamped by the mounting clip 42. At this time, the lower bracket 34 and the upper bracket 35 are folded according to the size of the wheel hub and the height of the employee to adjust the wheel hub to a suitable processing position. The wheel hub is then fixed by turning the first knob 33 and the second knob 37.
[0026] When performing wheel hub cutting and drilling, press the two slide rods 44 in opposite directions, rotate the retaining ring 48 to limit the slide rods 44, and the rubber pad 45 leaves the limiting groove 43. The wheel hub is fixed by the friction between the rubber pad 45 and the wheel hub. Rotating the ring seat 2 makes it easy to loosen the three second knobs 37 for adjustment, which is convenient for multi-angle drilling and cutting of the wheel hub.
[0027] When performing wheel hub painting and electroplating processes, rotating the retaining ring 48 causes the sliding rod 44 to slide. The sliding rod 44 drives the rubber pad 45 to slide into the limiting groove 43, so that the ball 47 contacts the recessed part of the wheel hub. The arrangement of multiple balls 47 facilitates the rotation of the wheel hub and makes it convenient for the wheel hub to be painted in all directions.
[0028] Through the above steps, by loosening the first knob 33 and the second knob 37, the lower bracket 34 and the upper bracket 35 can rotate freely. The wheel hub can be adjusted to a suitable position for the worker according to the size of the wheel hub and the height of the worker. The wheel hub is fixed by the friction between the rubber pad 45 and the wheel hub. Rotating the ring seat 2 makes it easy to loosen the three second knobs 37 for adjustment, which is convenient for multi-angle drilling and cutting of the wheel hub. The setting of multiple balls 47 facilitates the rotation of the wheel hub, so as to achieve the effect of convenient all-round spraying of the wheel hub.
[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
