Description

One kind refutes axis

Technical field

Mechanical material field is the utility model is related to, one kind is specifically related to and refutes axis.

Background technology

Refute axis usually to use as connector in mechanical apparatus field, refute the cheap of axis, refute the stability of axis connection Height, and axis connection generally use point branch mode is refuted, the area occupied of component is small, light and handy convenient, will not be to the device body of connection Function impact；There is a big advantage using the device for refuting shaft assembly connection, when device is subject to extraneous deformation force, refute axis The supporting item for refuting axis can be effectively directly passed to, eliminates damage of the external force to device.

But axis of the prior art of refuting is typically that a gap is set in the case where refuting shaft body, and fixed link is adjusted position Put, be positioned among the gap, be fixed afterwards with positioning jackscrew, it is spacing anti-refuting the tip of the axis with a trip bolt and playing De- effect, is typically that small casing is connected by the way of being spirally connected with big casing with female in the inside of big casing, The top center of small casing has the internal thread that is connected with screw empty, equally plays the role of positioning anticreep, but this kind Refute that the concentricity of axis is not high, influence the connection of casing and device, the stability after connection component is connected with device is not high；And mesh Preceding refuting is relatively complicated when being dismantled after axis is connected with supporting item, adds the workload of worker, reduces production efficiency.

Utility model content

The purpose of this utility model is to provide a kind of concentricity it is higher refute shaft assembly, make its have after being connected with device compared with Strong stability, while to refute axis again easy to disassemble after using for this kind, saves manpower, improves work efficiency.

In order to achieve the above object, the utility model is achieved through the following technical solutions：One kind refutes axis, including refutes axis Body, big casing and small casing, the big casing are fixedly connected on the left side for refuting shaft body, ensure concentricity, the small casing It is socketed in the big casing, ensures concentricity, this kind of structure can farthest ensures concentricity, and guarantee is refuted axis and connected with device Stability after connecing.

Further, the big casing is hollow structure, and front and rear sides center inside it is respectively horizontally arranged with One of slider bar, is respectively horizontally arranged with one of sliding slot, the sliding slot is pluggable in the front and rear sides center of shown small casing On the slider bar, and disengaging is slided in big casing using the slider bar, using described in the connection of this slide construction Large and small casing, the enhanced convenience during using installing, is spirally connected without carrying out rotation as refuting axis in the prior art, The set-up time is saved, improves service efficiency.

A position line is horizontally arranged with the centre position of the front and rear sides for refuting shaft body, in the position line , each side there is an ear room in upper end, axisymmetric equipped with other two in the lower end of the position line and upper end Liang Geer rooms A ear room.

Further, the ear room is hollow domes, has a positioning hole in the bottom of upper end ear room, in lower end ear There are positioning sky, the bottom location hole of the position line upper end ear room and the top of the lower end ear room of axial symmetry setting in the top of room Location hole through connection, is fixedly connected using positioning jackscrew through the location hole with the device to be connected afterwards, profit Prevent even if not connecting a trip bolt respectively in the front end for refuting the end of shaft body and small casing with this structure and may also function as positioning De- effect, saves process and material, effectively improves work efficiency.

The beneficial effects of the utility model are：This kind refutes axle construction concentricity height, the overall structure after being connected with device It is firm, effectively extraneous deformation force can be transformed into fixed link, reduce infringement of the external force to device, extend device uses the longevity Life；Meanwhile this kind is refuted axis and need to be only connected refuting the left and right sides of shaft body with fixed link using positioning jackscrew, when dismantling It is very convenient, the workload of worker is reduced, is improved work efficiency.
