Away from measuring device.It is particularly suitable for the center distance measurement of two circular holes of automobile connecting bar.
Background technology
It is both known about in automobile connecting bar processing industry, to measure the centre-to-centre spacing of two circular holes of connecting rod, must just find two circles accurately
The center in hole.At present, on connecting rod two center of circular hole away from measuring method be mostly using three-coordinate instrument.Although using three coordinates
Instrument can realize two center of circular hole away from measurement, but three-coordinate instrument is expensive so that equipment investment is more, production cost compared with
It is high.Again due to using three-coordinate instrument, many points need to be taken in circular hole surrounding, and pass through the center for calculating and just obtaining two circular holes
Away from working efficiency is low.
Invention content
The problem to be solved in the present invention is to provide a kind of center distance check tool.Connected using this center distance check tool to measure automobile
The centre-to-centre spacing of two circular holes on bar can reduce production cost, improve working efficiency.
The invention solves the above problem realized by following technical scheme：
The center distance check tool feature of the present invention is to include bottom plate and controller, and there are the first guide post and the second guide post in the longitudinal direction of bottom plate,
There is the spacing being adapted to two circular hole spacing of measured workpiece between first guide post and the second guide post.The first guide post lower end is the bottom of by
Seat is connected on bottom plate.Movable sleeve and fixing sleeve, pedestal and movable sleeve are cased with successively from bottom to top on the first guide post on pedestal
There is spring between surrounding, fixing sleeve is detachably connected on the first guide post.Fixing sleeve is equal with movable sleeve outer diameter and with being tested
The hole adaptation of workpiece, the neighboring terminal of fixing sleeve and movable sleeve is tapering point, there is retainer between two tapering points, on retainer
Steel ball is evenly equipped with, workpiece one end is sleeved on the neighboring terminal of fixing sleeve and movable sleeve and offsets with the steel ball.On second guide post
Section outer diameter is less than its hypomere and its epimere outer diameter is adapted to another hole of measured workpiece.Have that pass through it perpendicular on second guide post hypomere
To bore for rectangular flat hole, the longitudinal direction in the flat hole and the line of centres of measured workpiece holes are put down.Second guide post it is upper
There are vertical slot in the longitudinal both sides of section respectively, and the vertical slot is connected with flat hole below.There is vertical core on bottom plate corresponding with the second guide post,
Second guide post lower end is stretched into and is fixed in vertical core.There are preceding measuring staff and rear measuring staff in the flat hole, preceding measuring staff is vertical intermediate with after
Measuring staff has pin hole at its lower end, there is axis pin in pin hole, and two side of the axis pin both ends respectively with flat hole is connected.Before described
Measuring staff upper end is respectively protruding into corresponding vertical slot afterwards, and makes it and there are gaps between the inner circle in corresponding slot bottom and another hole of connecting rod.
The adjacent place near to the upper end of front and rear measuring staff has coaxial pin hole, has alloy pin in pin hole.The shorter than rear measuring staff in preceding measuring staff lower end.Second leads
Be fixed with limited block on the column side bottom plate adjacent with the first guide post, there are a pin hole and screw hole in limited block upper and lower part respectively, pin hole and
Have pin and bolt in screw hole respectively, there is tension spring between pin and preceding measuring staff lower end, in the middle part of the hypomere of bolt and rear measuring staff between be connected with push spring.
Have hole on rear measuring staff on tension spring, there is sensor in hole, sensor one end offsets with preceding measuring staff, the other end by conducting wire with
Controller is connected.
Further improvement of the present invention scheme is to be evenly equipped with axial blind hole, the two between the neighboring terminal surrounding of pedestal and movable sleeve
Axial blind hole on neighboring terminal is corresponding, and the both ends of the spring is respectively protruding into the corresponding axial blind hole on pedestal and movable sleeve.
Further improvement of the present invention scheme is that have pin hole on the side wall of movable sleeve, and guide pin is fixed in pin hole；With leading
There is vertical elongated slot on corresponding first guide post of pin, guide pin inner end is stretched into shape is slided in vertical elongated slot.
The further improvement project of the present invention is that the limited block is backward L-shaped, and the pin hole and screw hole are located at backward L-shaped
On the vertical part of limited block.
As can be seen from the above scheme, it is made of guide pin to adjust fixing sleeve, movable sleeve and retainer and steel ball
Tension mechanism in steel ball position ensure on connecting rod the tensioner positioning in a hole.Pass through the alloy bar and quilt of rear measuring staff upper end
It surveys another hole of connecting rod to be in contact, sensor inner end can be made to be in contact with preceding measuring staff.Since previous hole has positioned, two holes
Centre-to-centre spacing can be determined by measuring the center location in another hole.During measurement, preceding measuring staff and rear measuring staff are by hole where them
Size influence after rotating around rotation center carry out minor rotation, which is converted into digital signal through sensor and gives
Controller is shown after the Computing in controller, then by display therein.It is achieved thereby that two on connecting rod
The center distance measurement of circular hole.Compared with the three-coordinate measuring method in background technology, the expensive three-coordinate instrument of configuration is not required to, is reduced
Equipment investment, reduces production cost.The three-coordinate instrument expensive due to being not required to configuration again, is not required to after circular hole surrounding takes a little again
The center of circular hole can be just obtained by calculating, so as to greatly improve work efficiency.
