Abstract
The invention relates to a micrometer which comprises a stationary contact, a micrometering screw rod, a fixed sleeve, a differential cylinder, a ratchet wheel rotating cylinder, a connecting rod, a sleeve, a guide rail, a motor cell, a gauge frame, a switching button, a position switch, and the like, wherein an electric motor is additionally arranged on a ratchet wheel to replace manual rotation; the connecting rod on the electric motor is connected with a guide rail on the sleeve; the electric motor can move left and right on the guide rail in the sleeve; the position switch is used for carrying out stroke excess protection to prevent motor from being damaged by stroke excess; the sleeve is fixed on the gauge frame by a bracket; a cell is installed on the bracket for supplying power for a motor; and a change-over switch is arranged on the gauge frame to control the positive and negative rotation of the electric motor so as to achieve the aim of rapidly decreasing or increasing the distance between two contacts. The micrometer provided by the invention has the advantages of simplicity and rapidness for measurement, simple structure, convenience in operation, and the like.
Description
Technical field
The present invention relates to a kind of measurer, relate in particular to a kind of milscale.
Background technology
At present, known milscale has two relative contacts, the reading of milscale is the distance between two contacts, during measurement, these two contacts are the contact measured element respectively, the reading of milscale is the thickness of element at this moment, armrest moves and rotates chaste tree wheel and drive microdrum the distance between two contacts is changed, but because manual operation microdrum rotational speed is limited, when measured value and milscale when actual value differed too big at that time, or after receiving milscale use end, during the box tool of packing into keeping, all want the expensive time to rotate microdrum and be transferred to our needed big probable value, so in use, always require a great deal of time and adjust milscale, thereby wasted a large amount of time.Also have the people once patent of invention number be 200710202193.9 milscale, it comprises two relative contact and auxiliary fixtures, comprise a fixed cover and a contact site to auxiliary fixture, the length of this fixed cover is fixing, and on the contact located therein, this fixed cover has and this another gauge head opposing end faces.This contact site is fixed in this end face, this contact site is used for contacting with the thin part of this element under test, the surface of contact of this contact site and element under test is first distance with respect to the distance of the end face of this fixed cover, this element under test be second distance in the part of the relative side of this fixed cover with respect to the distance of the surface of contact of this contact site and this element under test than thickness portion, this first distance is greater than this second distance.This milscale adopts auxiliary fixture to measure the thickness of thickness smaller portions of the element of uneven thickness, and need not to change the milscale than small dimension, but this milscale more complicated in use, and makes mistakes easily in the process that converts.
Summary of the invention
In order to overcome the deficiency of above-mentioned milscale, it is accurate to the invention provides a kind of measurement, can save the very long time of rotating microdrum, the milscale of high efficiency.
The technical solution adopted for the present invention to solve the technical problems is: it comprises static contact a kind of milscale, micrometering screw rod, fixed muffle microdrum, compositions such as chaste tree wheel rotating cylinder.Described brambles rotating cylinder afterbody is connected with electro-motor.
Described electro-motor is arranged on the guide rail above the sleeve, and has position switch to make overtravel protection.
Described sleeve links to each other with connecting rod, and is fixed on the chi frame, and battery is housed on the connecting rod.
Switch and electro-motor and battery Electricity Federation are installed on the described chi frame.
The invention has the beneficial effects as follows: have simple to operately, easy to use, can dwindle or increase distance between two contacts fast and make advantages such as measuring simple and fast.
Description of drawings
Fig. 1 is a structural diagrams intention of the present invention.
1 is static contact among the figure, and 2 are the micrometering screw rod, and 3 is fixed muffle, and 4 is microdrum, and 5 are chaste tree wheel rotating cylinder, and 6 is connecting rod, and 7 is sleeve, and 8 is guide rail, and 9 is electro-motor, and 10 is battery, and 11 is the chi frame, and 12 is switching button, and 13 is position switch, and 14 is support, and 15 is scale.
Embodiment
Below in conjunction with accompanying drawing the present invention is specifically further specified.As shown in Figure 1,1, a kind of milscale it comprise static contact 1, micrometering screw rod 2, fixed muffle 3 microdrums 4, chaste tree wheel rotating cylinder 5 compositions such as grade.Described brambles rotating cylinder 5 afterbodys are connected with electro-motor 9.
Described electro-motor 9 is arranged on the guide rail 8 above the sleeve 7, and has position switch 13 to make overtravel protection.
Described sleeve 7 links to each other with connecting rod 6, and is fixed on the chi frame 11, and battery 10 is housed on the connecting rod 6.
Switch 12 and electro-motor 9 and battery 10 Electricity Federations are installed on the described chi frame 11.
Principle of work:
Switch 12 during use on the operation chi frame 11; the rotating of control electro-motor 9; thereby driving chaste tree wheel rotating cylinder 5 rotates; replace traditional armrest to rotate the chaste tree wheel; reach the purpose of measurement; there is the guide rail 8 above connecting rod 6 and the sleeve 7 to link to each other on the electro-motor 10; electro-motor 9 is when rotating; variation along with the distance between contact; electro-motor 9 can be on the guide rail 8 of sleeve 7 the insides move left and right; and there is position switch 13 to make overtravel protection in case the excess of stroke is damaged motor; when we to dwindle between two contacts apart from the time; press the just commentaries on classics button of switch 12; electro-motor 9 drives chaste tree wheel rotating cylinder 6 and rotates; when having testee to hinder between two contacts; device for measuring force in the chaste tree wheel rotating cylinder will make the idle running of chaste tree wheel rotating cylinder; when we to increase between two contacts apart from the time; as long as press the invert button of switch 12; electro-motor 9 just drives 5 counter-rotatings of chaste tree wheel rotating cylinder; thereby the counter-rotating that drives microdrum reaches the distance that increases between two contacts, and motor 10 can be depressed the position switch 13 that is located in the sleeve 7, disconnecting circuit when being inverted to certain limit simultaneously; motor 9 quits work, and reaches the effect of protection.
