One kind is used for twin grinder thickness of workpiece measuring mechanism
The utility model belongs to a kind of thickness measure mechanism, is mainly used for twin grinder and the thickness of workpiece to be machined is surveyed
Measuring mechanism, realization expeditiously obtain high-precision workpiece.
At present in electronics, optical articles manufacturing, general twin grinder used, to its workpiece to be machined thickness
Control all be grinding a period of time after, stop machine, and worker takes out workpiece from machine measurements, such as be not up to needs thickness
It puts back in machine and grinds again when spending size, then shut down detection again, machine is put back to again when being such as also not up to the thickness needed
Middle grinding, so repeatedly, time-consuming, inefficiency.
In twin grinding, since certain products need stringent control thickness of workpiece size, precision is needed to reach 0.05mm
Within.The attrition process time is mostly now empirically determined by worker in production, it is sometimes desirable to which repeated measurement slightly makes without paying attention to
Workpiece is overproof to be scrapped.
Utility model content
The main task and purpose of the utility model be：According to existing twin grinder in control workpiece to be machined thickness gauge
It is insufficient existing for very little aspect, a set of mechanism is designed, to replace artificial detection.Fundamentally overcome twin grinder low production efficiency
Under, the phenomenon that thickness qualities are difficult to ensure that, reaches effectively guarantee thickness of workpiece quality, hence it is evident that improve production efficiency.
The main technical schemes of the utility model：Mechanism includes displacement sensor, swivel nut, nut, movable sleeve, outer water blocking
Circle, interior retaining ring, screw, support shaft；Concrete structure, displacement sensor are connected to by swivel nut, nut on movable sleeve, movable sleeve
Be fixed by screws in support shaft and can up and down adjustment, pass through screw on movable sleeve and outer retaining ring be installed, outer retaining ring is with pacifying
Interior retaining ring on lathe sun wheel seat, jointly protects displacement sensor；The movable sleeve, top are provided with two
A symmetrical slot, middle and lower part are also opened there are two different slots；The support shaft, top are opened there are one slot.
The utility model is proved by practical application：Purpose of design is fully achieved,：Twin grinder realizes work in-process
Implement automatic detection, side processing, while being measured to thickness of workpiece, when workpiece reaches required thickness to thickness of workpiece
When, grinder autostop, hence it is evident that improve more than production efficiency three times；Control thickness of workpiece precision can reach 0.01mm with
It is interior, it is fully able to meet the needs of production and user.

Fig. 8 is the C-C of Fig. 7 to sectional view.
With reference to Fig. 2, the main technical schemes of the utility model are illustrated：Mechanism includes displacement sensor (standard
Part) 1, swivel nut 2, nut 3, movable sleeve 4, outer retaining ring 5, interior retaining ring 6, screw 7, support shaft 8；Concrete structure, displacement sensing
Device 1 is connected to by swivel nut 2, nut 3 on movable sleeve 4, and movable sleeve 4 is fixed in support shaft 8 by screw 7 and can go up downward
It saves, outer retaining ring 5, outer retaining ring and the interior retaining ring 6 on lathe sun wheel seat is installed by screw on movable sleeve 4,
Displacement sensor is protected jointly.
With reference to Fig. 4,5,6, the movable sleeve 4, top is opened there are two symmetrical slot, and middle and lower part also opens that there are two different
With reference to Fig. 7,8, the support shaft 8, top is opened there are one slot.
With reference to Fig. 2,3, the installation of the utility model, the utility model top is mounted in lathe lower wall sun wheel seat 9
Between in hole, lower part is fixedly mounted on lathe base 13.
With reference to Fig. 3, the operation principle of the utility model（The coordination of each power drive mechanism and action is in the control of software
Lower progress）：After the utility model is mounted on lower disc component, disk 11 declines in operation, is pressed on the workpiece 14 of lower wall 12, connects simultaneously
The shift fork 10 for connecting disk is also contacted with the contact 1-1 of displacement sensor 1, and displacement sensor numerical value is zeroed at this time；In the control of software
Under system, lathe upper lower burrs start to grind workpiece, and thickness of workpiece is constantly thinning in process of lapping, and upper disk 11 constantly declines, position
The contact 1-1 of displacement sensor 1 is compressed, and works as position data（Thickness data）When reaching requirement, lathe is stopped naturally, processing
Terminate.Its thickness precision qualification rate of the workpiece processed is up to absolutely.
Attrition process principle equipped with the utility model is identical with former twin grinder, and which is not described herein again.
