Description
Technical Field
The utility model belongs to the field of precision detection, and particularly relates to a thin-wall cylindrical part size detection device.
Background
For a large-depth thin-wall cylindrical component, the ultrathin and longer structural characteristics lead the component to be large in flexibility and poor in stability, and the component is easy to be unstable in the spinning process of a long stroke and difficult to judge the forming precision after spinning due to the structural characteristics of easy deformation. The state of the thin-wall cylinder in the spinning process is unknown, and the size and the forming precision after each pass of spinning are not comprehensively detected. Because of the rheological property of spinning, the overall structure of the workpiece presents certain flexibility, so that the workpiece is easy to deform in the corresponding manufacturing and detecting processes, and the difficulty of the post-spinning forming precision is increased. Conventional contact inspection methods are no longer suitable for size inspection of such workpieces.
The sealing property and the fluidity of the spinning process of the thin-wall cylinder ensure that the state judgment of the spinning process is still mainly based on the traditional artificial touch feeling. The corresponding characteristics and spinning conditions still have the problems of poor spinning stability, poor forming precision, difficult state monitoring, low size detection precision and the like in the spinning process of the thin-wall cylinder. With the development of sensors, ultrasonic waves, gratings, lasers and computer technology, the detection of the size of large thin-walled parts is developed from contact type to non-contact type. The traditional sensor rotary type laser measurement method adopts a point laser displacement sensor to calculate a data point set obtained by rotating a circle around a workpiece to be measured, the data has locality, and the data is mainly only detected by the inner wall and the outer wall of the workpiece in an independent size, so that the detection efficiency is low, and the measurement accuracy is low due to the influence of deformation and the like of a thin-wall cylindrical member when the measurement is performed at different times.
Disclosure of Invention
In order to solve the problems, the utility model discloses a size detection device for a thin-walled cylindrical part.
In order to achieve the above purpose, the technical scheme of the utility model is as follows:

Further improvements are made, wherein the inner wall telescopic measurement structure and the outer wall telescopic measurement structure both comprise screw rod mechanisms; the lead screw mechanism of the inner wall telescopic measurement structure is connected with an inner wall line laser displacement sensor, and the lead screw mechanism of the outer wall telescopic measurement structure is connected with an outer wall line laser displacement sensor.

Further improvement, the rotating device comprises a main motor, wherein the main motor is connected with a coupler through a speed reducer, the coupler is connected with a magnetic driving wheel, and an angle encoder is arranged in cooperation with the magnetic driving wheel; the magnetic driving wheel is in transmission connection with a magnetic driven wheel; the magnetic driving wheel is connected with the inner wall line laser sensor mounting bracket, and the magnetic driven wheel is connected with the outer wall line laser sensor mounting bracket.
Further improved, the movable workpiece clamping component and the fixed workpiece clamping component are respectively a first three-jaw chuck and a second three-jaw chuck. The first three-jaw chuck is connected to a X, Y shaft guide rail screw below through a two-way moving plate in a sliding manner; the annular mounting ring of the second three-jaw chuck is fixedly arranged on the frame through a gap between the magnetic driving wheel and the magnetic driven wheel.
Further improvement, the magnetic driving wheel is connected with the output shaft through a flat key. The magnetic driven wheel is fixedly connected with the annular guide rail sliding table and moves along the annular guide rail in a rotating way.
Further improvement, the base mounting panel below is fixed with the base frame, and base frame bottom is fixed with the base foot rest.
The utility model has the advantages that:
1. the detection efficiency can be greatly improved. The traditional detection device only measures the inner wall or the outer wall singly for detecting the thin-wall cylinder, and the detection device can detect the data of the inner wall and the outer wall simultaneously, so that the efficiency of detecting the size of the workpiece is greatly improved.
2. Avoiding deformation of the workpiece caused by contact measurement. Aiming at the characteristics of large flexibility and poor stability of the thin-wall cylinder, non-contact detection is adopted, the detection device is not in direct contact with the inner wall and the outer wall, and workpiece deformation caused by contact is avoided, so that detection data are inaccurate.
3. The linear laser displacement sensor is not affected by mechanical jitter errors, the accuracy of measured data points is higher, and the environment anti-interference capability is stronger. The traditional sensor rotary type laser measurement method adopts a point laser displacement sensor to calculate a data point set obtained by rotating a circle around a workpiece to be measured, and the data has locality. The measuring method of the utility model is based on the contour data obtained by the linear laser displacement sensor for calculation.
