Description

Technical Field

[0001] The utility model relates to the technical field of coaxiality detection of shaft parts, and more specifically, to a coaxiality detection device for shaft parts. Background Art

[0002] Coaxiality detection is a common problem encountered in the measurement of shaft parts. The general detection process is to clamp the shaft parts, then bring the probe of the micrometer into contact with the shaft parts, and then measure them by rotating the shaft parts. During the rotation process, the surface roughness of the shaft parts is inconsistent, so it will be reflected on the micrometer.

[0003] The utility model patent with patent announcement number CN209445957U discloses a coaxiality detection device for shaft parts, which belongs to the field of mechanical processing detection technology; it includes: a base, an angle plate and a plug gauge; the base is used as the basis of the overall device to provide the installation and fixing position of the plug gauge and the angle plate; the angle plate is connected to the base by screw II and positioned by cylindrical pin II; a V-shaped groove is opened on one side of the angle plate for axial positioning with the V-shaped surface of the part; the plug gauge is connected to the base by screw I and positioned by cylindrical pin I; a group of step holes are provided in the middle of the plug gauge for radial positioning of the circumference of the part; the center of the step hole of the plug gauge is coaxial with the center of the V-shaped groove of the angle plate. Compared with the existing technology, the utility model has a simple structure and is easy to operate. It can accurately detect the coaxiality and assembly of parts, ensure the rapid and accurate assembly of parts, and improve the detection efficiency of the coaxiality of batch processed parts.

[0004] However, when this structure is actually used, it is not convenient to detect shaft parts of different sizes when detecting shaft parts, and the detection process mainly relies on technical personnel to operate and read, and the detection efficiency is low. Therefore, a coaxiality detection device for shaft parts is proposed. Utility Model Content

[0005] In order to overcome the above defects of the prior art, the utility model provides a coaxiality detection device for shaft parts to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a coaxiality detection device for shaft parts, comprising a base plate, a rotating clamp is installed on the base plate, a slide rail is provided on one side of the rotating clamp, a slider is installed on the slide rail, a distance adjustment component is connected to one side of the slider, a lifting component is installed on the top of the slider, a detection component is supported on the top of the lifting component, and the detection component is arranged in coordination with the rotating clamp.

[0007] By placing shaft parts on the rotating clamp for centering and clamping, adjusting the height position of the detection assembly through the lifting assembly, and then adjusting the distance between the detection assembly and the shaft parts through the distance adjustment assembly, the detection end of the detection assembly is against the outside of the shaft parts, thereby being able to detect shaft parts of different sizes, and by clamping the shaft parts with the rotating clamp for rotation, the detection assembly can detect the distance from each point from the outer surface of the shaft parts to the axis center, thereby determining the coaxiality, and by lifting and lowering through the lifting assembly, the detection assembly can be lifted and lowered along the surface of the shaft parts, thereby being able to perform coaxiality detection on the entire length of the shaft parts.

[0008] Preferably, the distance adjustment assembly comprises a drag block and an electric push rod, the drag block is installed on one side of the slider, and the drag block is connected to the electric push rod.

[0009] Preferably, the lifting assembly includes an electric telescopic rod and a support plate, the bottom end of the electric telescopic rod is vertically mounted on the slider, the top end of the electric telescopic rod is mounted with the support plate, and the top end of the support plate supports the detection assembly.

[0010] Preferably, the detection component includes a laser rangefinder, a storage tube, a spring, a baffle and a detection rod. The laser rangefinder is installed on a support plate. The detection end of the laser rangefinder is connected to the storage tube. A spring is arranged in the storage tube. A baffle is crimped on one side of the spring. The baffle is connected to the detection rod.

[0011] Preferably, a through hole is provided in the storage tube, and the detection end of the laser rangefinder is connected and cooperated with the through hole.

[0012] Preferably, a mounting groove is formed at the end of the detection rod, and a ball is installed in the mounting groove.

[0013] Technical effects and advantages of the utility model:

[0014] 1. By extending the electric push rod, the drag block can drag the slider to move on the slide rail, so that the distance between the detection component and the shaft parts can be adjusted. At the same time, the abutment force between the detection component and the shaft parts can be adjusted so that it can accurately approach the outer surface of the shaft parts, but not too tight to affect the detection results, so as to realize the detection of shaft parts of different sizes;

[0015] 2. The support plate can be raised or lowered by extending the electric telescopic rod, so that the height of the detection component can be adjusted so that the detection component can scan and detect along the entire length of the shaft parts, thereby improving the comprehensiveness and accuracy of the detection.

[0016] 3. When the ball is pressed against the shaft parts for coaxiality detection, the ball is squeezed by the shaft parts, causing the baffle at the end of the detection rod to squeeze the spring, thereby changing the distance between the baffle and the laser rangefinder, so that the coaxiality of the shaft parts can be detected. The ball can roll to reduce the friction between the shaft parts, making the detection process smoother. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] During specific implementation, the electric push rod 502 is extended so that the drag block 501 can drag the slider 4 to move on the slide rail 3, so that the distance between the detection component 7 and the shaft parts can be adjusted. At the same time, the abutment force between the detection component 7 and the shaft parts can be adjusted so that they can accurately approach the outer surface of the shaft parts, but not too tight to affect the detection results, thereby realizing the detection of shaft parts of different sizes.

[0027] The lifting assembly 6 includes an electric telescopic rod 601 and a support plate 602 . The bottom end of the electric telescopic rod 601 is vertically mounted on the slider 4 .
