Abstract
The utility model discloses a positioning and detecting device of a thin-wall and conical-surface disc type workpiece. The positioning and detecting device includes a pedestal. The bottom of the pedestal is provided with cushion blocks. The lower end of a shaft sleeve is connected with the pedestal. The upper end of a rotary positioning shaft is provided with three through holes which are evenly arranged. Magnetic columns are arranged in the through holes. The lower part of the rotary positioning shaft is arranged in the shaft sleeve. A precise steel ball is arranged on the lower end of the rotary positioning shaft and in a through hole in the pedestal. The upper end of the precise steel ball is embedded into a central ball socket on the lower end of the rotary positioning shaft, and is positioned via a steel ball spacing ring in a clamping manner. The positioning and detecting device is simple in structure, accurate and firm in positioning, high in detection precision, and is easy to operate, thus being suitable for the positioning and detection of the thin-wall and conical-surface disc type workpiece.
Description
Technical field
The utility model belongs to a kind of location and pick-up unit of workpiece, is specifically related to a kind of location and pick-up unit that is used for the thin-walled conical surface disk workpiece of mechanical industry.
Background technology
For thin-walled conical surface disc type work, because its thin-walled characteristic, in machining process, very easily deform, and workpiece is conical surface umbrella, all the time, be difficult to its edge jitter and right alignment are accurately detected.But, because the edge jitter of workpiece has material impact to the mechanical property of assembly parts, so in assembling, need a kind of feasible detection means rationally that its edge jitter is accurately measured especially.
Summary of the invention
The utility model proposes in order to overcome the shortcoming that exists in the prior art, its objective is location and pick-up unit that a kind of thin-walled conical surface disk workpiece is provided.
The technical scheme of the utility model is: a kind of location and pick-up unit of thin-walled conical surface disk workpiece, comprise base, and the bottom of base is provided with cushion block, and the lower end of axle sleeve is connected with base.The upper end of revolution locating shaft is formed with three through holes that are uniformly distributed with, and is provided with the magnetic post in the through hole, and the bottom of revolution locating shaft is installed in the inside of axle sleeve, is provided with steel ball in the lower end of revolution locating shaft, and the steel ball spacing ring compresses the location with steel ball.
On described base, form through hole and connecting hole respectively.
Between described base and bolt, be provided with baffle plate.
The beneficial effect of the utility model:
The revolution locating shaft of the utility model is as core component, and the collection workpiece locate, compressed, revolute function and the whole body, has realized usefulness more than one, has farthest simplified the structure of installing.The radial location of workpiece cooperates realization through revolution locating shaft boss with the workpiece centre interporal lacuna, and the locating shaft end face is processed into the angle identical with the workpiece cone angle, and workpiece realizes that with the locating shaft end face line contacts when guaranteeing to measure, thereby realizes radial location.
In revolution locating shaft end 3 powerful magnetic posts are set in axial direction, give workpiece, realize axial compression with axial suction; Snap-in force can be adjusted through increasing or subtract small magnetic rod and workpiece distance, guarantees that the snap-in force that applies neither can make the workpiece secondary deformation, is difficult for again in measuring process, coming off.Revolution locating shaft and the processing of axle sleeve match grinding, tolerance clearance is merely 0.005mm; Simultaneously, the rational big L/D ratio design of the same employing of locating shaft and axle sleeve, the influence that tolerance clearance is brought to rotating accuracy drops to minimum, and radially revolution is beated in 0.005mm, reaches the level of precision bearing system.
Coaxial center pit nest is designed in revolution locating shaft lower end; Be equipped with accurate steel ball; In conjunction with flatness is the wimet baffle plate of 0.01mm, and when making the locating shaft revolution, its positioning table end face edge is beated and is merely 0.005mm; Reduce the influence that the jitter values of frock itself is brought to measured value as far as possible, reflect that to greatest extent the true edge of workpiece is beated.
