Magnetic handwheel

Abstract

The invention discloses a magnetic handwheel. The wall surface of an accommodating area which is in the centre of the handwheel body and is sleeved with a wheel-shaped body is provided with a plurality of embedded parts, wherein the embedded parts are provided with magnetic bodies which extend towards the wheel-shaped body so that the wheel-shaped body can produce a magnetic auxiliary positioning effect of non-direct contact friction with the handwheel body during the rotation to simplify a structure, effectively reduce assembly working procedures and further achieve the substantial benefitsof no mechanical wear and accurate positioning; and in addition, the wall surface of the accommodating area of the handwheel body is provided with the plurality of embedded parts, so the quantity of the magnetic bodies can be increased and reduced according to the hand feeling demand of operation positioning, thereby having the added value of highly flexible application.

Description

technical field [0001] The invention relates to an electronic hand wheel in a computer numerical control machine tool (CNC). Background technique [0002] see figure 1 and figure 2 As shown, the structure of the electronic handwheel currently used in computer numerical control machinery (CNC) machine tools includes: [0003] The handwheel body 50 has an accommodating area 51, and a central shaft 53 of a bearing 52 is provided at the central position of the accommodating area 51 for socketing the wheel-shaped body 60, so that the wheel-shaped body 60 is located in the accommodating Placed in the area 51, and a limiting space 54 is formed at the periphery of the accommodating area 51, and the limiting space 54 is connected with a strip-shaped positioning groove 55 for the elastic limiting group 70 to be disposed therebetween; [0004] The wheel-shaped body 60, wherein the hole 61 corresponds to the central axis 53 of the hand-wheel body 50 is sleeved in the hand-wheel body...

Problems solved by technology

[0007] However, due to the structure of the above-mentioned existing electronic handwheel, it is to rely on the stopper 72 of the elastic limit group 70 to carry out a single tooth between the highest position and the lowest position of the concave and convex tooth-shaped part 62 of the wheel-shaped body 60 through the elastic member 71. Toggle positioning, so the manufacturer can produce the required functions in order to achieve the core structure of the above-mentioned electronic handwheel, so that the entire process of design, production and assembly between the handwheel body 50 and the elastic limit group 70 parts can still be completed. Many labor-hour constraints and tooling cost issues must be taken into account

[0008] In addition, the above-mentioned existing electronic handwheel uses the stopper 72 protruding from the handwheel body 50 to produce direct friction with the surface of the concave and convex tooth-shaped part 62 of the wheel-shaped body 60 through the elastic contact of the elastic member 71. The contact fit will cause mechanical wear problems after a period of use. This wear problem alone will affect the unstable quality of the entire electronic handwheel and the accuracy of the positioning feel, and will also shorten the service life of the electronic handwheel structure.
