Abstract
The utility model discloses a guide mechanism which comprises a guide sleeve (1) and a guide pillar (3), wherein the guide pillar (3) is arranged in the guide sleeve (1), a circle of groove is arranged in the guide sleeve (1), a bush (2) is arranged in the groove, and a layer of lining (4) is arranged between the bush (2) and the guide pillar (3). According to the utility model, through a structure that the bush is arranged in the guide sleeve and matched with the lining, the guide sleeve can achieve an effect of high concentricity and small gap with the guide pillar under the condition that the machining accuracy of the guide sleeve is not high.
Description
Technical field
The utility model relates to the guide mechanism of a kind of guide mechanism, particularly a kind of vertical lift.
Background technique
Traditional vertical lift guide mechanism; Basically continue to use the simple mode that directional post is set in the guide sleeve, but this navigation mode is had relatively high expectations to material chosen and concentricity precision; Otherwise under the bigger situation of pressure; Make the eccentric aggravation of directional post easily, thereby cause frictional force to increase, and cause bigger noise.And long-term use can cause than galling, and the gap of directional post and guide sleeve is progressively become greatly, and the stability of guiding also can reduce gradually.For fear of the problems referred to above, adopt the method that improves machining accuracy and material wear-resistant performance usually, but will certainly improve cost of production greatly like this.
The model utility content
The purpose of the utility model is, a kind of guide mechanism is provided.It can guarantee the gap and the concentric rate of directional post and guide sleeve, and reduces the required precision of component processing.
The technological scheme of the utility model: a kind of guide mechanism, comprise the directional post in guide sleeve and the guide sleeve, be characterized in: be provided with a circle groove in the said guide sleeve, be provided with lining in the groove, also be provided with one deck liner between lining and the directional post.
In the above-mentioned guide mechanism, said guide sleeve comprises two axially part guiding pieces of symmetry, is equipped with connecting plate on two part guiding pieces, passes through screw between the connecting plate, two part guiding pieces is held tightly be fixed into complete pipe shape guide sleeve.
In the aforesaid guide mechanism, said liner is wear-resisting glue-line (an available polytetrafluoroethylene floor).
In the aforesaid guide mechanism, said lining is axially arranged with opening, is the pipe shape that does not seal.Therefore entire mechanism allows each parts that the certain precision error is arranged from the can regulate state.
Compared with prior art, the utility model is through being provided with lining and cooperating the structure of liner in guide sleeve, can make guide sleeve under machining accuracy is not very high situation, can realize high concentric rate and little gap with directional post.The utility model not only can each parts requirement on machining accuracy, reduce production costs, and can effectively reduce noise and wearing and tearing.The utility model can reduce production costs more than 30%, and the noise that directional post goes up and down can be reduced to below 70 decibels.
