Description
Technical field
The utility model relates to a kind of measurement instrument.
Background technology
Milscale force measuring machine commonly used has two kinds, the most commonly is installed in the ratchet force measuring machine of milscale afterbody, and another kind is mounted in the force measuring machine on the microdrum, its patent No. 95228434.0, and name is called " milscale force measuring machine ".First kind of force measuring machine needs the bimanualness milscale, or milscale is fixed on the bearing, and using is not easily, when especially measuring little or light part; Second kind of force measuring machine can the one-handed performance milscale, and the another hand is taken tested part, uses more conveniently, but can not satisfy traditional use habit.In order to overcome above-mentioned shortcoming, the milscale that has has been used above-mentioned two kinds of force measuring machines simultaneously, but the ergometry size of two force measuring machines is difficult for making unanimity, and cost also increases to some extent in addition.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art to provide a kind of easy to use, simple in structure, makes easily, satisfies the monoblock type milscale force measuring machine of multiple requesting.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of monoblock type milscale force measuring machine, comprise micrometric screw, fixed hub, microdrum, the dynamometry overcoat, spring leaf, its principal feature is, described dynamometry overcoat is made up of the large cylinder of left end and the small cylinder of right-hand member, and the dynamometry overcoat is enclosed within on the microdrum, and dynamometry overcoat endoporus is provided with hook tooth, on microdrum, be provided with groove with hook tooth opposite position place, one spring leaf is arranged between dynamometry overcoat and microdrum, and an end of spring leaf is fixed in the groove of microdrum, the hook tooth Elastic Contact of the other end and dynamometry overcoat, the tail end of dynamometry overcoat is provided with dog screw, and dynamometry overcoat outside surface is provided with anti-skid design.
The beneficial effects of the utility model are: a kind of easy to use, simple in structure, make easily, and satisfy the monoblock type milscale force measuring machine of multiple requesting, be applicable to various micrometer measuring implements, external diameter series milscale for example, internal diameter series milscale.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cut-open view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
Embodiment: a kind of monoblock type milscale force measuring machine, comprise micrometric screw 42, fixed hub 43, microdrum 45, dynamometry overcoat 46, spring leaf 44, described dynamometry overcoat 46 is made up of the large cylinder of left end and the small cylinder of right-hand member; Dynamometry overcoat 46 is enclosed within on the microdrum 45, dynamometry overcoat 46 endoporus are provided with hook tooth 49, hook tooth 49 opposite position places with the dynamometry overcoat on microdrum 45 are provided with groove, one spring leaf 44 is arranged between dynamometry overcoat 46 and microdrum 45, one end of spring leaf 44 is fixed in the groove of microdrum 45, the other end and hook tooth 49 Elastic Contact, the tail end of dynamometry overcoat 46 is provided with dog screw 47, and dynamometry overcoat 46 outside surfaces are provided with anti-skid design.
During use, forward (dextrorotation) rotates dynamometry overcoat 46, by the friction force of spring leaf 44 with hook tooth 49 inclined-planes, driving microdrum 45 rotates, this moment, micrometric screw 42 and microdrum 45 relied on conical surface self-lock force to rotate together thereupon, screw pair by fixed hub 43 and micrometric screw 42 compositions, micrometric screw 42 and microdrum 45 produce synchronous straight-line displacement, rotate dynamometry overcoat 46 as reverse (left-handed), the free end of spring leaf 44 withstands on the stop surface of hook tooth 49, driving microdrum 45 reverse sync rotates, because the left end large cylinder of dynamometry overcoat 46 and the small cylinder of right-hand member can be handed rotation, and can apply identical ergometry, overcome the shortcoming of milscale force measuring machine noted earlier.
Application examples: a kind of external diameter series milscale of using the utility model structure, as Fig. 1, shown in Figure 2, when using this milscale, forward (dextrorotation) rotation dynamometry overcoat 46, spring leaf 44 under the effect of elastic force with the inclined-plane Elastic Contact of the hook tooth 49 of dynamometry overcoat 46, and produce constant friction force, relying on this friction force to drive microdrum 45 rotates, micrometric screw 42 and microdrum 45 rely on conical surface self-lock force to rotate together thereupon, screw pair by fixed hub 43 and micrometric screw 42 compositions, micrometric screw 42 and microdrum 45 produce synchronous straight-line displacement, at this moment, can read measured value by microdrum 45, because it is constant driving the friction force that produces when micrometric screw 42 rotates, so the ergometry that the measurement face of micrometric screw acts on the tested part also is constant, thereby reach the purpose of accurate measurement, can catch on milscale chi frame 41 with the right hand little finger of toe during use, thumb and forefinger rotate the large cylinder of dynamometry overcoat 46, also can hold milscale chi frame 41 or be clamped on the special-purpose rod support of milscale with left hand, the right hand rotates the small cylinder of dynamometry overcoat 46 and measures, and satisfies the needs when measuring different part and the use habit of different crowd.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
