Abstract
A kind of adjustable bow compass and its application method belong to machining measurer field, solve the problems, such as that certain outside diameter measurings are difficult.Its structure have the fixed bracket of arc (1), spring (2), screw rod (3), handle (4), location nut (5), two measuring jaws (6)；(1) (6) the fixed bracket of arc is fixed two measuring jaws, so that two measuring jaws is (6) passed through screw rod by the elastic force of spring (2) (3) can free opening and closing；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 present invention is suitable for the outside diameter measuring that some special shapes or special occasions are often used with measurer inconvenience.
Description
Technical field
The invention belongs to be machined common measurer field, it is related to outside diameter measuring.
Background technique
In being machined live components measurement work, have the geometric dimension of some components due to by special shape or
The influence of special occasions, common measuring tool, such as vernier caliper, straight steel ruler, tape measure can not measure, therefore use outer
Clamp measure.But common bow compass in measurement due to the not positioning to measuring size between measuring jaw, by external force
Be affected, therefore its to measure size error larger.
Summary of the invention
The purpose of the invention is to overcome the problems, such as that existing clamp error in measurement process is larger.
Adjustable bow compass, structure have: arc fixed 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 fixed bracket 1 of the arc, pass through two measuring jaws 6 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 measurement model
In enclosing；
3. two measuring jaws 6 of clamp to be tightened to the size that can easily enter 7 outer diameter of workpiece with hand, outer wall is put into, it is left-handed
Thumb and index finger grapple the lower part card base of two card bases, by spring force 2 make it open should make two angle of nips measuring surface on line
Just it is vertically intersected on the axis of outer wall, i.e. the two of the angle of nip measuring surface same end face two-end-point that should be outer diameter；
4. should be parked in the measuring surface of following angle of nip when measurement as fulcrum on 7 outer wall of workpiece, angle of nip above is to outside workpiece
Diameter maximum is gradually soundd out outward, and is swung along outer wall circumferencial direction, when the distance that can be swung along outer wall circumferencial direction is maximum
When, 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 be surveyed with vernier caliper
Measure the size that the distance between two angle of nips are exactly measured outer diameter.
When measurement it should be noted that
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, with fixture nut modulation other end measuring jaw with
The contact of workpiece maximum outside diameter, shakes look for Maximum Contact point back and forth.
The advantages of this clamp is: structure is simple, and it is convenient to operate, and measurement is accurate, has low in cost, has a wide range of application etc. excellent
Point.This clamp is due to being the positioning using the opening and closing of spring adjusting measuring jaw, by location nut to measuring size, therefore measurement error
It is small.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention,
In figure: the fixed bracket of 1 arc, 2 springs, 3 screw rods, 4 handles, 5 location nuts, 6 measuring jaws, 7 workpiece.
Specific embodiment
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: the fixed bracket 1 of arc, spring 2, screw rod 3, handle 4, positioning spiral shell
Female 5, two measuring jaws 6；Two measuring jaws 6 are fixed up by the fixed bracket 1 of the arc, make two amounts by the elastic force of spring 2
Pawl 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 measuring jaws of clamp
Crankle shape, grab tip position sheet is made because it measure outer diameter when pawl grab point with diameter wall point contact, closed in this way in jaw
It will not collide and interfere with outer wall on the inside of measuring jaw when conjunction, 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 measurement model
In enclosing；
3. two measuring jaws 6 of clamp to be tightened to the size that can easily enter 7 outer diameter of workpiece with hand, outer wall is put into, it is left-handed
Thumb and index finger grapple the lower part card base of two card bases, by spring force 2 make it open should make two angle of nips measuring surface on line
Just it is vertically intersected on the axis of outer wall, i.e. the two of the angle of nip measuring surface same end face two-end-point that should be outer diameter；
4. should be parked in the measuring surface of following angle of nip when measurement as fulcrum on 7 outer wall of workpiece, angle of nip above is to outside workpiece
Diameter maximum is gradually soundd out outward, and is swung along outer wall circumferencial direction, when the distance that can be swung along outer wall circumferencial direction is maximum
When, 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 be surveyed with vernier caliper
Measure the size that the distance between two angle of nips are exactly measured outer diameter.
The present invention is suitable for some components due to being influenced by special shape or special occasions, commonly measures work
The inconvenient outside diameter measuring used of tool.
