A turning tool for model racing wheels

Abstract

The invention discloses a turning tool used for a model racing bicycle wheel. The turning tool comprises a linear cylindrical guide rail assembled on a bottom plate, a shaft sleeve installed on the peripheral surface of the linear cylindrical guide rail in a sleeving mode, a turning tool arm fixed to the shaft sleeve and a turning tool body fixed to the turning tool arm. The shaft sleeve can move and rotate along or around the center axis of the linear cylindrical guide rail, the two movements are independent of each other without mutual influences, and therefore feeding of the turning tool body is achieved. The axis of the linear cylindrical guide rail is perpendicular to the rotating axis of the wheel clamped to the tool, a straight long turning tool edge is perpendicular to the axis of the linear cylindrical guide rail, and then the model racing bicycle wheel is turned accurately. The turning tool has the advantages that in the prior art, the track of turning tool feeding is changed into a circular arc from a straight line, sharing of feeding components is achieved, and the turning tool is simple in structure, good in portability and low in cost.

Description

technical field [0001] The invention relates to the field of turning the circumferential surface of tires on wheels, in particular to the field of turning tires of model racing cars. Background technique [0002] Model racing cars have high requirements on the stability of the tire contact area and the radial runout of the tire circumferential surface. These two parameters affect the grip of the tire and the ride comfort. However, there are parting lines and burrs on the surface of new tires. During the high-speed rotation of the tires during model racing competitions, when the parting lines and burrs on the tire surface contact the ground, they will slightly lift the tires, reducing the ground contact area, thus The grip of the tire is reduced; and because the tire and the rim are randomly assembled, the accumulation of errors between the two will cause a large radial runout error on the tire circumferential surface. The rolling radius is different, which affects the ride ...

However, there are parting lines and burrs on the surface of new tires. During the high-speed rotation of the tires during model racing competitions, when the parting lines and burrs on the tire surface contact the ground, they will slightly lift the tires, reducing the ground contact area, thus The grip of the tire is reduced; and because the tire and the rim are randomly assembled, the accumulation of errors between the two will cause a large radial runout error on the tire circumferential surface. The rolling radius is different, which affects the ride comfort of the model car

[0003] The existing technology is based on the structure of the ordinary lathe, and the design is reduced and simplified to be a lathe that can turn the wheel assembly of the model racing car, and the tread of the wheel assembly is turned. Although the above-mentioned purpose can be achieved, because the ordinary lathe structure is used, the structure Complicated, takes up a lot of space, and poor portability

Because the feeding and cutting functions of traditional tools need to be realized by two sets of linear motion units, four sets of brackets, four sets of linear cylindrical guide rails, two sets of screws, two sets of screw bearings, two sets of handwheels, and two sets of The scale and two sets of locking mechanisms are very expensive
