Description
Technical Field
The invention relates to a measuring device, in particular to a shaft part dimension measuring device based on DIC.
Technical Field
At the present stage, vernier calipers are generally adopted for measuring the circumference and other dimensions of circular shaft parts, if the radial dimension of one section of the circular shaft parts is measured, the radial dimension can only be roughly compared by the vernier calipers or other tools, the precision is not enough, for some articles with larger diameters, the vernier calipers cannot be clamped by clamping jaws and also cannot be accurately measured, and for some stepped shafts, the measurement is generally divided into two times, so that the convenience and the rapidness are not enough. Especially, the continuous measurement of the circumferential dimension of the shaft part and the variation of the different circular cross-sectional dimensions are difficult to measure and compare.
Disclosure of Invention
In order to solve the defects of the prior art, the invention provides the shaft part size measuring device based on the DIC.
In order to achieve the purpose, the invention adopts the following technical scheme:
the DIC-based shaft part size measuring device comprises a motor fixing seat, wherein a motor is arranged on the motor fixing seat, an output shaft of the motor is connected with a lead screw, the outer side of the lead screw is sleeved with a sliding sleeve through a screw, a through hole is formed in the upper end of the sliding sleeve, a probe is arranged in the through hole, a thrust ring is arranged on one side, located in the sliding sleeve, of the outer wall of the probe, a spring is sleeved between the thrust ring and the bottom surface of the sliding sleeve on the outer side of the probe, and speckle mark points are; a binocular camera for shooting probe motion image is installed on the support.
The motor fixing seat of the device is connected with the rotating device of the workpiece to be detected, the motor rotates, the screw rod drives the sliding sleeve to slide left and right, and then the probe is driven to be in continuous contact with the surface of the workpiece to be detected under the pressure of the spring. The workpiece to be measured keeps rotating at a constant speed, so that the probe can measure the external dimension of the workpiece to be measured in the moving process.
The surface of the probe is filled with uniformly distributed mark point speckles in an ink-jet mode, the speckles are used as reference points when the DIC binocular detection system measures, and the size of the surface of a workpiece can be obtained after the DIC binocular detection system shoots a moving image of the probe and the moving image is processed by a computer. DIC binocular detection system, it is the simulation human eye, through two cameras of left and right sides acquireing the image, and then carry out position calculation according to the mark speckle, its computational accuracy is very high.
A probe with higher hardness is fixed at the contact part of the probe and the workpiece to be measured, so that the probe is prevented from being worn too fast in the measuring process to influence the measuring precision.
The device for holding the workpiece may be a machine tool, a simple rotating device, or a device capable of measuring without rotating the workpiece.
According to the invention, the overall dimension of the workpiece is calculated through the DIC binocular detection system, the high precision of measurement can be ensured, and the detection is convenient and rapid.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Labeled as: 1 motor fixing base, 2 motors, 21 lead screws, 3 thrust rings of probes, 4 springs, 5 sliding sleeves, 6 speckles of probes, 7 workpieces, 8 probe heads of probes, 9DIC binocular detection system's binocular camera, 10 supports, 11 workpiece clamping devices.
Detailed Description
Referring to the attached drawings, the DIC-based shaft part size measuring device comprises a motor fixing seat 1, a motor 2 is installed on the motor fixing seat, an output shaft of the motor is connected with a screw rod 21, the outer side of the screw rod is sleeved with a sliding sleeve 5 through a screw, a through hole is formed in the upper end of the sliding sleeve, a probe is installed in the through hole, a thrust ring 3 is arranged on one side, located in the sliding sleeve, of the outer wall of the probe, a spring 4 is sleeved between the thrust ring and the bottom surface of the sliding sleeve on the outer side of the probe, and a speckle mark; a binocular camera 9 for photographing a probe moving image is installed on the stand 10.
When measuring, fixed with the work piece, remove about driving sliding sleeve 5 through motor 2, the probe contradicts the work piece surface and moves forward and retreat along with the height on surface, and DIC binocular detection system's two cameras shoot the probe motion image in real time, and the surface size of work piece is calculated to speckle through the probe surface, accomplishes the measurement of high accuracy.
