Abstract
The utility model relates to a micrometer force measuring mechanism. The inner layer of the micrometer force measuring mechanism is provided with a differential cylinder, and the outer layer is provided with a ratchet sleeve; a spring lamination is arranged between the differential cylinder and the ratchet sleeve; a small groove is arranged on the differential cylinder; one end of the spring lamination is bent into a small hook to hang in the small groove on the differential cylinder, and the other end contacts a ratchet tooth of an inner bore of the ratchet sleeve at the outer layer by means of the elasticity of the spring lamination. When the ratchet sleeve forwardly rotates, the free end of the spring lamination contacts the slope of the ratchet tooth, the constant frictional force is generated, and therefore, the differential cylinder is driven to rotate. When the installing direction of the spring lamination and the installing direction of the ratchet sleeve are turned for 180 DEG, the force measuring direction can be changed. The mechanism which has the advantages of simple structure, convenient batch production and convenient use is suitable for various micrometer measuring tools.
Description
The utility model relates to a kind of measurement instrument.
Existing milscale force measuring machine is two ratchet force measuring machines, its complex structure, and part is many, makes difficulty, and can only be installed in the afterbody of milscale, uses inconvenient operation, and this structure can not realize two-way dynamometry.
The purpose of this utility model overcomes above-mentioned shortcoming exactly, provides a kind of simple in structure, makes easily, can change the dynamometry direction, and can guarantee the milscale force measuring machine of request for utilization.
The purpose of this utility model realizes like this: its internal layer has microdrum, skin has and has a sulculus on the ratchet sleeve microdrum, the ratchet sleeve endoporus has hook tooth, there is a spring leaf microdrum outside, one end of spring leaf curves a little hook, hang in the sulculus of microdrum, the other end is free state, rely on the elasticity of itself to contact with the hook tooth of the ratchet sleeve endoporus of its outside, the long inclined-plane of hook tooth is a rubbing surface, and short facing directly is stop surface, during the ratchet sleeve forward rotation, the free end of spring leaf contacts with the hook tooth inclined-plane, produces constant friction force (being the milscale dynamometry), rotates thereby drive microdrum.During the backward rotation ratchet sleeve, the free end of spring leaf withstands on the stop surface of hook tooth, and microdrum is reversed together.The utility model only needs that the installation direction of spring leaf and ratchet sleeve is turned 180 ° can change the dynamometry direction, thereby realizes that same structure has two-way dynamometry.
The utility model is simple in structure, is convenient to produce in batches, and is easy to use, good looking appearance.Be applicable to various micrometer measuring implements, for example: external diameter series milscale, internal diameter series milscale.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model embodiment.
As figure is to adopt outside micrometer of the present utility model, when using this milscale, forward rotation ratchet sleeve (6), spring leaf (7) contacts with ratchet sleeve (6) under the effect of elastic force, and produce constant friction force, relying on this friction force to drive microdrum (4) rotates, because jackscrew (8) is connected as a single entity microdrum and micrometric screw (1), so micrometric screw (1) also rotates thereupon, by the screw pair of axle sleeve (2) with micrometric screw (1) composition, micrometric screw (1) and microdrum (4) produce synchronous axial straight-line displacement, because the friction force that micrometric screw (1) is rotated is constant, so the axial ergometry that is applied on the micrometric screw (1) also is constant, at this moment, can read measured value by microdrum (4) and fixed sleeving (3).Thereby reach the purpose of accurate measurement.The effect of regulating nut (5) is the gap of adjustable screw pair.As counter-rotation ratchet sleeve (6), the free end of spring leaf (7) withstands ratchet, and the stop surface of tooth (12) reverses microdrum (4) together, and can drive micrometric screw (1) and draw back.When using milscale of the present utility model, can be because ratchet sleeve (6) and chi frame (10) distance are very near only with a manual manipulation milscale, that is: hook chi frame (10) with little finger, thumb and forefinger rotating ratchet cover (6), the another hand is held tested part, use before this miking, can use annular knurl cap (9) fast moving micrometric screw (1) earlier, re-use force measuring machine and accurately measure near measured value.The utility model can also change the dynamometry direction easily, only needs ratchet sleeve (6) and spring leaf (7) are turned round 180 °, has just changed the dynamometry direction.
Claims (1)
1, a kind of milscale force measuring machine, the internal layer that it is characterized in that it has microdrum (4), skin has ratchet sleeve (6), between microdrum (4) and the ratchet sleeve (6) spring leaf (7) is arranged, have sulculus (11) on the microdrum (4), ratchet sleeve (6) endoporus has hook tooth (12), and an end of spring leaf (7) curves a little hook, hang in the sulculus (11) on the microdrum (4), the other end is free state and contacts with the hook tooth of ratchet sleeve (6) endoporus.
