Abstract
A kind of adjustable bow compass belongs to mechanical processing measurer field, solves the problems, such as that certain outside diameter measurings are difficult.Its structure have arc fixing bracket (1), spring (2), screw rod (3), handle (4), location nut (5), two measuring jaws (6)；(1) (6) arc fixing bracket is fixed two measuring jaws, make two measuring jaws (6) (3) can free opening and closing by screw rod by the elastic force of spring (2)；The distance between (6) two measuring jaws (5) can be locked by location nut；(6) two measuring jaws of clamp are crankle shapes.(6) outer wall that two measuring jaws of clamp are entered to workpiece when use, makes the on line of the measuring surface of two angle of nips be vertically intersected on the axis of outer wall, is then two maximum endpoints of workpiece outer diameter when the distance that can be swung along outer wall circumferencial direction is maximum；(5) location nut locks the position, be exactly the size of measured outer diameter with the distance between two angle of nip of vernier caliper measurement.The utility model is suitable for the outside diameter measuring that some special shapes or special occasions are often used with measurer inconvenience.
Description
Technical field
The utility model belongs to the common measurer field of mechanical processing, is related to outside diameter measuring.
Background technology
In the live parts of mechanical processing measure work, there is the geometric dimension of some parts due to by special shape
Or the influence of special occasions, common survey tool, such as vernier caliper, straight steel ruler, tape measure can not measure, therefore use
Bow compass measures.But common bow compass when measuring due to the not positioning to measuring size between measuring jaw, by
External force is affected, thus its to measure size error larger.
Invention content
The purpose of this utility model is to overcome existing clamp in measurement process the larger problem of error.
Adjustable bow compass, structure have：Arc fixing bracket 1, spring 2, screw rod 3, handle 4, location nut 5, two
A measuring jaw 6；Two measuring jaws 6 are fixed up by the arc fixing bracket 1, so that two measuring jaws 6 is passed through by the elastic force of spring 2
Screw rod 3 can free opening and closing；The distance between two measuring jaws 6 can be locked by location nut 5；Two measuring jaws of clamp are crankles
Shape grabs tip position and sheet is made.
Application method：
1. whether all parts for debugging the clamp are intact, and activity is normal；
2. adjust 6 aperture of measuring jaw of bow compass, see measured 7 part of workpiece outer diameter whether the clamp survey
It measures in range；
3. two measuring jaws 6 of clamp are tightened to hand can easily enter the size of 7 outer diameter of workpiece, outer wall is put into, with a left side
The thumb and index finger of hand grapple the lower part card base of two card bases, and the measuring surface of two angle of nips should be made by so that it is opened by spring force 2
On line is just vertically intersected on the axis of outer wall, i.e. the two of angle of nip measuring surface should be the same end face two-end-point of outer diameter；
The measuring surface of following angle of nip should be parked on 7 outer wall of workpiece when 4. measuring and be used as fulcrum, angle of nip above is to work
It gradually sounds out at part largest outside diameter, and is swung along outer wall circumferencial direction outward, when the distance that can be swung along outer wall circumferencial direction is
When maximum, then it represents that two measuring surface of wild card angle of nip have been in two maximum endpoints of 7 overall diameter of workpiece；
5. location nut 5 is locked to the position, gently clamp are removed, avoids colliding with workpiece, then uses vernier calliper
Ruler measures the size that the distance between two angle of nips are exactly measured outer diameter.
It should be noted that when measurement：
A. the measurement range of vernier caliper measurement clamp, i.e. its minimum and maximum measured value are used；
Clamp must be vertical with the axis of measured workpiece when b. measuring；
Clamp one end measuring jaw gently touches at the outer wall of measured workpiece when c. measuring, and another looking somebody up and down is modulated with fixing nut
Pawl is contacted with workpiece maximum outside diameter, shakes look for Maximum Contact point back and forth.
The advantages of this clamp is：Simple in structure, simple operation, it is accurate to measure, and has of low cost, has a wide range of application etc. excellent
Point.This clamp is due to being the positioning by location nut to measuring size using the opening and closing of spring adjusting measuring jaw, therefore measurement error
It is small.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model,
In figure：1 arc fixing bracket, 2 springs, 3 screw rods, 4 handles, 5 location nuts, 6 measuring jaws, 7 workpiece.
Specific implementation mode
In conjunction with attached drawing, clamp construction and its application method are described in detail：
As shown in the picture, adjustable bow compass, structure have：Arc fixing bracket 1, screw rod 3, handle 4, is determined spring 2
Position 5, two measuring jaws 6 of nut；Two measuring jaws 6 are fixed up by the arc fixing bracket 1, make two by the elastic force of spring 2
A measuring jaw 6 can free opening and closing by screw rod 3；The distance between two measuring jaws 6 can be locked by location nut 5；Two, clamp
Measuring jaw is crankle shape, grab tip position sheet is made because it measure outer diameter when pawl grab point with diameter wall point contact, clamping in this way
It will not collide and interfere with outer wall on the inside of measuring jaw when mouth is closed, be convenient for the free opening and closing of measuring jaw.
Application method：
1. whether all parts for debugging the clamp are intact, and activity is normal；
2. adjust 6 aperture of measuring jaw of bow compass, see measured 7 part of workpiece outer diameter whether the clamp survey
It measures in range；
3. two measuring jaws 6 of clamp are tightened to hand can easily enter the size of 7 outer diameter of workpiece, outer wall is put into, with a left side
The thumb and index finger of hand grapple the lower part card base of two card bases, and the measuring surface of two angle of nips should be made by so that it is opened by spring force 2
On line is just vertically intersected on the axis of outer wall, i.e. the two of angle of nip measuring surface should be the same end face two-end-point of outer diameter；
The measuring surface of following angle of nip should be parked on 7 outer wall of workpiece when 4. measuring and be used as fulcrum, angle of nip above is to work
It gradually sounds out at part largest outside diameter, and is swung along outer wall circumferencial direction outward, when the distance that can be swung along outer wall circumferencial direction is
When maximum, then it represents that two measuring surface of wild card angle of nip have been in two maximum endpoints of 7 overall diameter of workpiece；
5. location nut 5 is locked to the position, gently clamp are removed, avoids colliding with workpiece, then uses vernier calliper
Ruler measures the size that the distance between two angle of nips are exactly measured outer diameter.
The utility model is suitable for some parts due to being influenced by special shape or special occasions, commonly surveys
The outside diameter measuring that amount tool inconvenience uses.
