Embodiment 1

[0025] Embodiment 1: as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 In the shown embodiment, a tire nut fastening device includes an air gun joint 1, a main shaft 2, and four driven parts 3, and the four driven parts are evenly distributed around the outside of the main shaft with the main shaft axis as the center line. The driven part includes a power frame 4, a sleeve joint 5 for fastening tire nuts, a driven gear 6 for driving the sleeve joint to rotate, the driven gear is in the power frame, and the power The frame is provided with a sleeve bearing, and the sleeve joint is connected with the sleeve bearing. The main shaft is provided with a driving gear 7 coaxial with the main shaft, and the driving gear meshes with each driven gear.

[0026] When it is necessary to fasten the tire nuts on the tire, you can put the four tire nuts on one tire into the sleeve joint respectively (this sleeve joint is directly matched with the tire nut, and if the tire nut need...

Embodiment 2

[0035] Embodiment 2: the basic structure and implementation mode of this embodiment are the same as embodiment 1, and its difference is, as Figure 6 , Figure 7 As shown in , the driven gear and the sleeve joint no longer have structures such as ratchets and tooth grooves, but adopt the structure of driving ball 31 and driving groove 32, as follows: figure 2 As shown in , the power frame is provided with an adjustment cylinder coaxial with the driven gear, one end of the adjustment cylinder extends into the power frame, and one end of the adjustment cylinder is provided with an adjustment pressure screw threaded with the adjustment cylinder. The other end of the adjustment cylinder is facing the driven gear. The adjustment cylinder is provided with an adjustment push rod. A spring is arranged between one end of the adjustment push rod and the adjustment pressure head. The other end of the adjustment push rod contacts the driven gear. One end face, the other end face of the ...

Abstract

The invention discloses a tire nut fastening device, and aims to provide a fastening device which is reasonable in structure, can effectively screw automobile tire nuts, is stable and efficient in working process and can ensure that the tightening degrees of four tire nuts on one tire are basically consistent. The tire nut fastening device comprises an air gun joint, a main shaft and four driven parts, wherein the four driven parts are uniformly and annularly distributed on the outer side of the main shaft from the axial line, serving as a central line, of the main shaft; the driven parts comprise power frames, sleeve joints for fastening the tire nuts and driven gears for driving the sleeve joints to rotate; the driven gears are located in the power frames; sleeve bearings are arranged on the power frame; the sleeve joints are connected with the sleeve bearings in a matched manner; a driving gear coaxial with the main shaft is arranged on the main shaft; the driving gear is meshed with each driven gear.

Description

technical field [0001] The invention belongs to the field of tire nut assembly devices, in particular to a tire nut fastening device. Background technique [0002] Several (four) tire nuts are usually arranged on the automobile tire, and the wheel is connected and fixed with the axle shaft through the tire nuts. At present, when the tire nuts of automobiles are fastened, it is mostly realized by means of air guns, nut wrenches, etc. However, there are usually four tire nuts on a wheel, and the tire nuts need to be tightened one by one when installing the tire. The force is too large. [0003] Chinese Patent Publication No. CN201516550U discloses a portable car electric tire nut dismounting machine, which includes a housing, a main shaft, and a motor. The key is that a clutch device is arranged between the main shaft and the motor. The clutch device includes a hammer barrel, a clutch spring, an internal spline and a swing block; the bottom of the hammer barrel is provided ...
