Abstract
The utility model discloses a numeral-point type antishock caliper centigrade meter, which is a replaced product of the vernier caliper and is a precision measuring instrument used to measure the inside dimension, outside dimension, depth and step of the machine part. The utility model has the advantages of beautiful appearance, bi-directional antishock function, visual and exact reading number and no visual error. The utility model is composed of a caliper body (1), a caliper frame (11) sheathed outside the caliper body (1), a meter head (6) arranged on the caliper frame, a rack (8) arranged in the central slot of the caliper body (1), a graduated strip (2) and a depth ruler (10).
Description
The utility model belongs to surveying instrument, is a kind of slide calliper rule dial gauge of measuring the inside and outside size of part, the degree of depth and step.
Vernier caliper, milscale are the most frequently used survey instruments of mechanical component dimensional measurement, and major defect is, reading inconvenience, visual angle error are big.
The purpose of this utility model is, a kind of two shockproof thousand chi dial gauges of numeral pointer-type with gauge outfit are provided, and can directly show measurement size, solves the inaccurate problem of reading.Simultaneously, the utility model has designed shockproof structure, to solve collision and vibration problem, guarantees its usability.
The technical solution of the utility model is: former vernier caliper has been done improvement.Its structure is: on blade (1), suit chi frame (11), chi frame (11) can be gone up at blade (1) and slide, gauge outfit (6) and stop screw (5) are housed on the chi frame (11), in the Middle Trough of blade (1), tooth bar (8) is housed, pressing scale strip (2) on the tooth bar (8), left side in the gauge outfit (6), right tooth axle (15,20) and tooth bar (8) engagement, on the chi frame (11), also be fixed with pit gauge (10), pit gauge (10) can move and slides in the blade Middle Trough with chi frame (11), blade (1) and chi frame (11) front end stretch out inner measuring jaw (3) and outer measuring jaw (12), in order to inside dimension and the outside dimension of measuring measured part.Stop screw is in order to fixedly blade and chi frame relative position.At the blade afterbody, plate washer (9) is housed also.At the front end of chi frame, have with the chi moving directrix (4) of frameing shift.
Gauge outfit (6) is by housing (13) and be contained in that transmission shockproof assembly, table in the housing covers (16), dial plate (14), lining ring (21), needle pivot (17), pointer (18), zeroing thumb wheel (7), upper and lower clamping plate (23,24) are formed.Zeroing thumb wheel (7) is to be contained on the housing (13) by bearing pin (22), and some is exposed at outside the housing, is convenient to adjust with hand rubbing is moving.
The transmission shockproof assembly is by the left and right tooth axle (15,20) that is installed on the upper and lower clamping plate (23,24), and the gear of installing on the left and right tooth axle (29,30), the clockwork spring (25), clockwork spring stator (26), the shockproof stator (28) that reach in the last installation of left tooth axle (15) are formed.
During measurement, pulling gauge outfit (6), then chi frame (11) is in company with moving, the left and right tooth axle (15,20) that is contained in the rack drives gauge outfit (6) on the blade (1) rotates, the gear (30) that is installed in the gear (29) on the tooth axle (15) and is contained on the tooth axle (20) rotates with the tooth axle, the pointer (18) that drives needle pivot simultaneously and be contained in the needle pivot top is in upward rotation of dial plate (14), thus the scale value that exactness one turns over.The scale value of the rule bar (2) that directrix is aimed at reads integral part, and the scale that is turned on dial plate by gauge outfit (6) pointer reads fraction part.
Shockproof principle: owing on the transmission shockproof assembly, adopted this energy storage flexible member of clockwork spring (25),, discharge again, play two-way antihunt action so can store impulsive force.
The utility model has the advantages that: 1, have two-way shockproof function, overcome transportation or use in the possibility that reduces of the precision that caused of collision, 2, reading is intuitively accurate, overcome the collimation error.3, elegant in shape, pointer only need be stirred thumb wheel (7) to zero, and is easy and simple to handle.
The drawing explanation:
Fig. 1 is the utility model structural representation
Fig. 2 is the gauge head structure synoptic diagram
Fig. 3 is the vertical view of Fig. 2
Fig. 4 is gauge outfit tooth axle and blade middle rack mesh schematic representation
Below in conjunction with accompanying drawing and use-case, the utility model is further described.
Use is: 1, zeroing.Stirring thumb wheel (7) makes pointer (18) point to " 0 " value on the dial plate exactly.2, measure.Pulling chi frame (11), making the numerical value that the tested measuring jaw of measured workpiece (3 or 12) blocks, directrix (4) moves on scale strip (2) is round values, pointer is a fractional value in the indicated value of dial scale value.When fathoming, pit gauge (10) is inserted tested part, still at reading on the scale strip and on the gauge outfit.
Claims (4)
1, the two shockproof slide calliper rule dial gauges of a kind of numeral pointer-type, it comprise blade (1) and in, outer measuring jaw (3,12), it is characterized in that, on blade (1), suit chi frame (11), chi frame (11) can be gone up at blade (1) and slide, gauge outfit (6) and stop screw (5) are housed on the chi frame (11), in the Middle Trough of blade (1), tooth bar (8) are housed, scale strip (2) is pressed on the tooth bar (8), left side in the gauge outfit (6), right tooth axle (15,20) be meshed with tooth bar (8), also be fixed with pit gauge (10) on the chi frame (11), pit gauge (10) can move in the blade Middle Trough with chi frame (11) and slide, at blade (1) afterbody, plate washer (9) is housed also.
2, according to the described slide calliper rule dial gauge of claim 1, it is characterized in that gauge outfit (6) is by housing (13) and be contained in the interior transmission shockproof assembly of housing, table illiteracy (16), dial plate (14), lining ring (21), needle pivot (17), pointer (18), zeroing thumb wheel (7), go up lower plate (23,24) forms.
