Description
The utility model belongs to the measurement instrument technical field, relates in particular to a kind of dead-beat milscale.
In the existing micrometer measuring implement, two kinds of feed mechanisms are arranged, a kind of is rotary feed mechanism, and another kind is the dead-beat feed mechanism.The milscale of rotary feed mechanism can not be realized the translation of the face of measuring.The milscale of existing dead-beat feed mechanism then has complex structure, and surface of contact is many, and friction force is big, moves difficulty, and each error of perpendicularity that contacts end face directly influences defectives such as measurement face feed accuracy.
The purpose of this utility model is the shortcoming that overcomes existing dead-beat milscale, designs a kind of novel dead-beat milscale, simple in structure, easy mobile, feed accuracy advantages of higher that this milscale has.
The dead-beat milscale of this utility model is by movable gauge head, fixing gauge head, the chi frame, orienting sleeve, axle sleeve, the location edge of a knife, adapter sleeve, micrometric screw, fixed sleeving, microdrum, setting nut, Knurling drum, parts such as dynamometer spring are formed, orienting sleeve one end closely is connected with movable gauge head, the other end and adapter sleeve are with being threaded, fixedly gauge head is fixed on the chi frame, axle sleeve is sleeved on the orienting sleeve, ∨ shape groove on the orienting sleeve contacts with the ∨ shape location edge of a knife, one end of micrometric screw is fixed in the orienting sleeve by movable gauge head and adapter sleeve, micrometric screw is that point contacts with the surface of contact of movable gauge head, the other end is contained in the axle sleeve, Knurling drum is sleeved on the microdrum outside, between Knurling drum and microdrum dynamometer spring is housed, and microdrum is sleeved on the fixed sleeving, fixed sleeving is sleeved on the axle sleeve, and setting nut is sleeved on the axle sleeve afterbody.For the ease of fast moving, the micrometric screw afterbody can be provided with the fast moving device.In order to improve measuring accuracy, prevent that the human heat from importing the chi frame and bringing error to measurement, on the chi frame, be provided with backplate, play heat-blocking action.Backplate is two of front and back, heat-barrier material manufacturings such as available plastics, timber.Movable gauge head and fixedly gauge head be the parts that when measuring, block testee, movable gauge head in use can be along the micrometric screw axially-movable, so be referred to as movable gauge head, fixedly gauge head then is solidified as a whole with the chi body, maintains static during use, so be called fixedly gauge head.The chi frame is the support of milscale, and its end is fixed with fixedly gauge head, and the other end is fixed other parts by axle sleeve, forms the dead-beat milscale of an integral body.One ∨ type groove is arranged on the orienting sleeve, and it contacts with the ∨ type location edge of a knife, and make it and can not rotate, thus the accurate translation of the measurement face of realization.Axle sleeve is fixing micrometric screw and make it the parts of axially-movable, and it is sleeved on the orienting sleeve.The location edge of a knife is made as the ∨ type, in the use when it when ∨ type groove on the orienting sleeve contacts, just can prevent the orienting sleeve rotation.Adapter sleeve and orienting sleeve are with being threaded.The column part of micrometric screw is fixed in the endoporus of orienting sleeve by movable gauge head and adapter sleeve, and the threaded hole of threaded portion and axle sleeve is formed screw pair, and the effect of setting nut is the gap of adjusting this screw pair, prevents the micrometric screw play, guarantees measuring accuracy.Fixed sleeving and microdrum are provided with scale, form reading device.Fixed sleeving is sleeved on the axle sleeve, and microdrum then is sleeved on the fixed sleeving.Be provided with dynamometer spring between Knurling drum and microdrum, this spring is a spring leaf, and its effect is to guarantee that dynamometry is constant.
During use, the forward rotation Knurling drum, driving micrometric screw by microdrum and dynamometer spring rotates, micrometric screw promotion activity gauge head produces translation, movable gauge head closely connects together with orienting sleeve, and the ∨ type groove on the orienting sleeve is located by the ∨ type that the edge of a knife is spacing can not to rotate, and orienting sleeve is with the translation forward of movable gauge head, the distance of translation is read from fixed sleeving and microdrum, realizes the accurately purpose of measurement with this.
The movable gauge head sphere of this dead-beat milscale contacts for point with the micrometric screw end face, and friction force is very little, and the error of perpendicularity is also minimum to the feed accuracy influence, and micrometric screw other end and adapter sleeve are annular contact surface, so friction force is also very little.Thereby it has advantage simple in structure, that moving resistance is little, feed accuracy is high.
Fig. 1 is the example structure synoptic diagram of the utility model dead-beat milscale.
Fig. 2 is the A-A sectional structure synoptic diagram of Fig. 1.
Fig. 1 is among Fig. 2: 1 movable gauge head; 2 orienting sleeves; 3 axle sleeves; The 4 location edges of a knife; 5 adapter sleeves; 6 micrometric screws; 7 fixed sleevings; 8 microdrums; 9 setting nuts; 10 Knurling drums; 11 dynamometer springs; 12 fast moving devices; 13 chi framves; 14 backplates; 15 fixing gauge heads.
