DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0019] The present application provides a mechanical parts processing defect detection device, which is mainly used to solve the problem that when the flatness of mechanical parts is detected, a dial indicator is generally used for detection. The dial indicator is used by fitting the probe of the dial indicator to the surface of the workpiece, and then moving the workpiece or the dial indicator to observe the range of change of the reading of the dial indicator. Some workpieces often have annular edges. When performing a flatness detection operation on the annular edge, it is often difficult to perform a more comprehensive detection operation due to the special structure of the annular edge. The following technical solutions are provided. Figure 1-Figure 4 Make a detailed description:

[0020] A machine parts processing defect detection device comprises: a base 1 with a dial gauge 2 and a placement plate 3 arranged on the top, and a workpiece body 4 arranged on the placement plate 3. The user can adjust the position of the dial gauge 2 through an adjustment mechanism 5 so that the probe of the dial gauge 2 contacts the surface of the workpiece body 4, and then control the placement plate 3 to rotate through a driving mechanism 9, so as to achieve the measurement of the flatness of the annular edge of the workpiece, wherein the main components of the adjustment mechanism 5 are: a driving rail 501 fixedly mounted on the top of the base 1, and at the same time, the inner wall of the driving rail 501 is rotatably plugged with a driving rail 501. The first driving block 503 is connected to the driving threaded rod 502 by a threaded sleeve on the surface of the driving threaded rod 502. Therefore, when the user rotates the driving threaded rod 502, the first driving block 503 can be driven to slide on the inner wall of the driving rail 501. A moving rail 504 is fixedly installed on the top of the first driving block 503. The inner wall of the moving rail 504 is slidably plugged with a second driving block 505. A guide rod 506 is fixedly installed on the surface of the second driving block 505. A lifting threaded rod 507 is rotatably plugged on the surface of the second driving block 505. The surface of the lifting threaded rod 507 is threaded sleeve on the surface of the lifting threaded rod 507. The lifting frame 508 is connected to the guide rod 506, and the lifting frame 508 is slidably sleeved on the surface of the guide rod 506. Therefore, the user can drive the lifting frame 508 to move along the length of the guide rod 506 by rotating the lifting threaded rod 507. At the same time, the user can also change the lateral position of the lifting frame 508 by driving the second driving block 505 to slide on the inner wall of the movable rail 504. The lifting frame 508 also includes a damping shaft 509. The lifting frame 508 is rotatably mounted with a rotating rod 510 through the damping shaft 509. The user installs the dial indicator 2 at one end of the rotating rod 510 through the limiting mechanism 7. , the position of the dial indicator 2 can be adjusted, wherein the main components of the control mechanism 6 are: a motor 602 fixedly mounted on the top of the base 1, and a mounting frame 601 is fixedly mounted on the surface of the base 1, and the placement plate 3 is rotatably mounted on the surface of the mounting frame 601. Therefore, the user can drive the placement plate 3 fixedly mounted on the output end of the motor 602 to rotate, thereby realizing the driving of the workpiece body 4. It should be noted that the workpiece body 4 does not refer to a specific workpiece, and many existing workpieces have annular edges.

[0021] When in use, the user places the workpiece body 4 on the surface of the placement plate 3, and then adjusts the position of the dial indicator 2 through the adjustment mechanism 5 so that its probe contacts the surface of the imaginary edge of the workpiece body 4, and then controls the placement plate 3 to rotate through the driving mechanism 9, thereby driving the workpiece above to rotate, and the flatness of the annular edge of the workpiece body 4 can be observed on the dial indicator 2. This arrangement allows the flatness of the annular edge of the workpiece body 4 to be detected more intuitively, which fully reflects the practicality of the device.

[0022] like Figure 1As shown, in some embodiments, in order to further optimize the solution, two clamps 8 are arranged above the placement disk 3, and the two clamps 8 are respectively arranged on both sides of the workpiece body 4. The user can place the workpiece body 4 on the surface of the placement disk 3, and then control the two clamps 8 to clamp the workpiece through the driving mechanism 9, and then drive the placement disk 3 to rotate through the driving mechanism 9, so as to ensure the stability of the workpiece body 4 during the rotation process. The driving mechanism 9 includes a double-headed hydraulic rod 902 fixedly mounted on the surface of the placement disk 3, and the surfaces of the two clamps 8 are fixedly mounted with driving rods 901. The user drives the two ends of the double-headed hydraulic rod 902 to extend and retract at the same time, which can drive the driving rods 901 fixedly mounted on its two ends to move, thereby realizing the driving of the two clamps 8 at the same time.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
