The accuracy for whether being accurately directly related to later product of positioning.The mode of existing workpiece positioning is usually using artificial fixed
Position, then grabs processing stations by manipulator again, but mode is positioned manually and not can guarantee the accuracy of positioning.
Utility model content
In order to solve the above technical problems, the purpose of the utility model is to provide a kind of lifting rotation dresses that can be accurately positioned
It sets, specific technical solution is as follows:
A kind of lifting rotation positioning device, including rack, the rack include upper mounted plate, bottom plate, upper mounted plate
It is fixed with bottom plate by vertical plate, optical axis is set between fixed plate and bottom plate；Fixed plate, bottom plate
Between intermediate plate is set, the two sides of the intermediate plate are respectively set that linear bearing is a set of, and the linear bearing one is set in the light
On axis；Through-hole is arranged in the center of the intermediate plate, and the outer rim of rolling bearing is embedded in the through-hole；Institute is set on the outside of sleeve
It states in the inner hole of rolling bearing, the axial keyway of the inside setting of the sleeve, shaft is arranged in sleeve, and the outside of shaft
Feather key, the feather key and the keyway location matches are set；The lower end of the shaft passes through shaft joint and decelerating motor
Export axis connection；The lower end of the intermediate plate is connect by connector with cylinder piston rod；The top setting support cylinder of the sleeve, institute
State the upper surface setting silicon carbide layer of support cylinder.
Workpiece is arranged in the top of the support cylinder, and detection probe, the detection probe and control host is arranged in the top of workpiece
Connection.
Journey deck is adjusted in setting on the vertical plate, and protrusion, the protrusion and intermediate plate is arranged in the bottom for adjusting journey deck
Lower section abuts.
Bolt adjustment section is arranged in the connector.
The utility model has the advantages that: the rotational structure due to using decelerating motor driving, decelerating motor, which can be used, to be watched
Motor is taken accurately to control rotation angle, then is aided with the lifting device of cylinder driving, it is accurate up and down and rotation to realize support cylinder
Transhipment is dynamic.And the silicon carbide layer being arranged above cylinder is held in the palm, since the coefficient of friction between silicon carbide layer and workpiece is greater than workpiece and workpiece
Coefficient of friction between the detection probe of top, therefore, workpiece can be with support cylinder rotations, when workpiece rotation to predetermined position, detection
Location information can be transmitted to control host by probe, and control host, which can issue instruction, allows decelerating motor to stop rotating, thus accurately
Guarantee the rotation angle of workpiece.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the A-A position profile figure of Fig. 1；
Fig. 3 is outline structural diagram.
Specific embodiment
The utility model is illustrated with reference to the accompanying drawing, as shown, the utility model includes rack 1, the rack
Including upper mounted plate 2, bottom plate 3, upper mounted plate 2 and bottom plate 3 are fixed by vertical plate 21, and fixed plate 2 is under
Optical axis 4 is set between fixed plate 3；Intermediate plate 5, the side setting of the intermediate plate 5 are set between fixed plate 2, bottom plate 3
Linear bearing 1, the linear bearing 1 are set on the optical axis 4；Through-hole, rotation axis is arranged in the center of the intermediate plate 5
It holds in the 7 outer rim insertion through-hole；The outside of sleeve 15 is set in the inner hole of the rolling bearing 7, the upper end of sleeve 15
It is arranged in the inner hole of the linear bearing 28 on upper mounted plate；The axial keyway of the inside setting of the sleeve 15, shaft 22 are set
It sets in sleeve 15, and feather key 10 is arranged in the outside of shaft, the feather key 10 is with the keyway location matches and guarantee is led
Xiang Jianke is slided along shown keyway；The lower end of the shaft 22 passes through the output axis connection of shaft joint 11 and decelerating motor 12, excellent
Selection of land, decelerating motor use servo motor, have control host to control the rotation and stopping of servo motor；The intermediate plate 5
Lower end is connect by connector 19 with the piston rod of cylinder 20；The top setting support cylinder 13 of the sleeve 15, it is described to hold in the palm the upper of cylinder 13
Silicon carbide layer 14 is arranged in surface.
Workpiece is arranged in the top of the support cylinder 13, and detection probe is arranged in the top of workpiece, and the detection probe and control are led
Machine connection is transferred to control host to will test signal, and control host controls decelerating motor rotation according to signal detected
And cylinder is flexible.
For the maximum distance of fall for controlling intermediate plate, journey deck 18 is adjusted in setting on the vertical plate 21, the journey deck of adjusting
Bottom setting protrusion, the protrusion is abutted with the lower section of intermediate plate 5, and to be conveniently adjusted, bolt adjustment section, institute is arranged in the connector
The lower part for stating upper part and connector that bolt adjustment section is connector is bolted, and adjusts the bolt, so that it may in adjustment
Under two-part distance.
The operating method of the utility model is: cylinder drives intermediate plate to rise, until when predetermined position, decelerating motor actuating sleeve
Cylinder rotation, support cylinder and then rotate, and workpiece setting is on support cylinder, the probe of the top setting pressure of workpiece, pop one's head in lower end and workpiece
It abuts；Since the coefficient of friction between workpiece lower end and silicon carbide layer is greater than the coefficient of friction between workpiece and upper probe, and workpiece
It is greater than the contact area of workpiece and probe with the contact area of support cylinder, therefore, workpiece is rotated with support cylinder；To workpiece rotation to predetermined
When position, location information can be transmitted to control host by detection probe, and control host, which can issue instruction, allows decelerating motor to stop rotation
Turn, to accurately guarantee the rotation angle of workpiece.
