Abstract
The utility model discloses an instrument for measuring the internal diameter of a cycle trough, composed of a moving measuring head, a contact head, a changeable measuring head, a 90 DEG equal-arm lever inversely arranged, a locking apparatus, a push rod, and a gauge head. The contact head is fixed at the tail part of the moving measuring head, having the functions of contacts and guiding. The changeable measuring head is used for replacing a fixed measuring head, the changeable measuring head can be changed according to different measuring objects, applied to the measurement of the internal diameters of various cycle troughs, the 90 DEG equal-arm lever inversely arranged causes the displacement quantity of the moving measuring head to be increased, the convenience of putting in and taking off of the moving measuring head is ensured by the locking apparatus, and the utility model follows the Abbe measuring principle. The utility model has the advantages of small size, high measuring precision, convenient operation and use, and reliability. The measurement of the inner diameter of the deep hole cycle trough can be realized through lengthening the lengths of the push rod and a straight pipe.
Description
The present invention relates to a kind of measurer, particularly a kind of measurer of surveying the ring groove interior diameter.
Continuous development along with industry, people more and more pay attention to the sealing that how to improve axial workpiece, this is because the bad waste that not only can cause the energy, material of airtight quality, also can make and omit the thing contaminated environment, therefore, measure annular groove inner diameter size is the key that guarantees the axial workpiece airtight quality exactly.At present, recognize that from domestic and international various data and sample the measurer of measure annular groove interior diameter structurally is scissors fork structure, this kind structure has bigger defective on measuring principle, that is, do not meet Abbe's principle, in addition, on the rigidity of structure, also there is certain deficiency.For above-mentioned reasons, the most accurate scale division value of ring groove interior diameter scale is 0.02mm at present.
In view of the above-mentioned deficiency that the ring groove inner diameter measurement is existed, the purpose of this utility model is a kind of flexible operation of design, convenience, the ring groove interior diameter scale that measuring accuracy is high.
The utility model comprises main body, support, movable gauge head, movable gauge head spring, guide rod, push rod, straight tube, handgrip and gauge outfit; main body is connected by securing member with support; be slidingly matched between movable gauge head and the main body; in the movable gauge head is a cavity; spring is arranged in the chamber; spring center has guide rod; push rod outer cover straight tube; one end contacts with the gauge outfit contact; one end stretches into support, and its characteristics are the contact with contact and guide effect, interchangeable gauge head, the anti-locking device of adorning 90 ° of bascules and being made of locking pin, protective sleeve, locking pin spring and retainer.Movable gauge head afterbody and contact are connected, reduced the scale volume, instead adorned 90 ° of bascules, movable gauge head displacement is strengthened, replace fixedly gauge head with interchangeable gauge head, can be by adjusting, to change interchangeable gauge head and adapt to the measurement of the ring groove of different inner diameters, locking device enters tested ring groove after movable gauge head locking, movable gauge head stretches out after removing locking state, enter duty, measurement finishes and takes out after back activity compression gauge head is locked, and use, operation are reliably, conveniently.
The utility model is observed Abbe's principle on measuring principle, higher transmitting accuracy is arranged, structure enough rigidity are arranged on the whole, therefore can carry out the accurate measurement that scale division value is 0.01mm to ring groove.
Because this scale has been taked at movable contact afterbody fixed contact, movable gauge head has been provided with locking device, and take to replace the fixedly measure of gauge head and 90 ° of four aspects such as bascule with interchangeable gauge head, it is easy and simple to handle reliable that this scale is had, adapt to the measurement of various endless groove diameters, the high outstanding advantage of measuring accuracy, particularly taked the measure of 90 ° of anti-dresses of bascule, as long as lengthening push rod and length of straight pipe, can realize measurement, and this is that other ring groove measurer institute is inaccessiable at present to deep hole ring groove interior diameter.
In addition, can change the gauge outfit of different systems, thereby realize the measurement of two kinds of standards of public English according to different measurement requirement.
Further specify the utility model below in conjunction with accompanying drawing:
Fig. 1 assembly structure figure
This ring groove interior diameter scale is by main body (1); support (2); movable gauge head (3); contact (4); set nut (5); movable gauge head spring (6); guide rod (7); interchangeable gauge head (8); locking back of the body cap (9); 90 ° of bascules (10); spacer pin (11); locking pin (12); protective sleeve (13); locking pin spring (14); push rod (15); straight tube (16); retainer (17); handgrip (18) and gauge outfit (19) constitute; main body (1) is fastenedly connected by trip bolt with support (2); be slidingly matched between movable gauge head (3) and the main body; one locking step is arranged on the movable gauge head; one cavity is arranged in it; spring (6) is arranged in the cavity; under spring action, movable gauge head has outwardly directed trend all the time.Afterbody is fastening on it with contact (4) by set nut (5); at movable gauge head spring (6) center one guide rod (7) is arranged at movable gauge head; this guide rod is positioned between movable gauge head cavity and the interchangeable gauge head (8); to keep spring not crooked when being compressed; locking pin (12) is positioned at retainer (17); between locating slot and the movable gauge head (3); its underpart has a protective sleeve (13) to be fixed on the support (2); between locking pin (12) and the protective sleeve (13) locking pin spring (14) is arranged; locking pin drops on when movable gauge head is compressed to maximum displacement on the locking step, locking activity gauge head.Interchangeable gauge head (8) is locked at main body one side by locking back of the body cap (9), with the coaxial assembling of movable gauge head, 90 ° of anti-dresses of bascule, its two arm contacts with push rod (15) lower end and contact (4) respectively, with movable gauge head displacement 1:1 pass to push rod.The push rod upper end contacts with the gauge outfit contact, and there is straight tube (16) its outside, will measure main body and link to each other with gauge outfit.Handgrip (18) is positioned between gauge outfit and the retainer (17), plays a role in insulation, and during measurement handgrip part.Gauge outfit is indicated tested ring groove interior diameter with the pointer form, and its precision can reach 0.01mm.
