Technical Field

[0002] Machined parts are parts or components manufactured by mechanical processing methods. These parts are removed from the raw materials through cutting, grinding, drilling, milling, turning and other process methods to form finished products with specific shapes, sizes and surface quality. Machined parts need to be tested for burrs, mainly because the presence of burrs will have a negative impact on the quality, performance and safety of the parts. Burrs refer to sharp protrusions on the edge of the workpiece due to cutting, grinding and other operations during the machining process.

[0003] After searching, Chinese patent announcement number: CN218445186U discloses a burr detection device, which uses a clamping claw to clamp the workpiece to be inspected, and then uses a CCD camera to capture one side of the workpiece to be inspected. The driven tooth portion drives the rotating disk to rotate on the groove, so that the workpiece on the clamping claw is turned over by the flip arm, and the other side of the workpiece to be inspected is captured by the CCD camera, so as to perform a more comprehensive inspection of the workpiece to be inspected.

However, the accuracy of the camera for shooting detection is low. At the same time, it is impossible to provide comprehensive detection on four or more sides of the workpiece after it is clamped, thereby reducing the detection quality. Therefore, a burr detection tool for machined parts is proposed to solve the above problems. Utility Model Content

[0032] Reference Figure 1-Figure 3 The inner wall of the mounting groove 2 is opened on the upper surface of the base 1, and the positioning assembly includes a groove 5. The positioning assembly is provided with three groups, and the three groups of positioning assemblies are distributed in a circular array with the center point of the turntable 4 as the symmetry axis. The positioning assembly can fix three points of the machined part on the turntable 4. The inner wall of the groove 5 is threadedly connected with a threaded rod 7, and the end of the threaded rod 7 is fixedly connected with a handle 6. The forward and reverse rotation of the handle 6 can make the threaded rod 7 rotate and move the moving block 8 back and forth in the groove 5. The outer wall of the threaded rod 7 is threadedly connected with a moving block 8, and the top of the moving block 8 is fixedly connected with a bracket 9. The inner wall of the bracket 9 is slidably connected with a positioning member 10, and the surface of the bracket 9 is fixedly connected There is a spring 11, the elastic force of the spring 11 makes the positioning member 10 always keep away from the top of the bracket 9, so as to facilitate the fixation of the upper surface of the machined part. The driving assembly includes a guide rail 12, the outer wall of the guide rail 12 is slidably connected to a guide seat 13, the guide seat 13 can move back and forth on the guide rail 12, the top of the guide seat 13 is fixedly connected to an electric push rod 14, the output end of the electric push rod 14 is fixedly connected to a lifting plate 15, the electric push rod 14 can drive the lifting plate 15 to adjust the height, the groove 5 is opened on the upper surface of the turntable 4, the inner wall of the groove 5 is adapted to the outer wall of the moving block 8, and the lower surface of the guide rail 12 is fixedly connected to the upper surface of the base 1.

[0033] Reference Figure 1-Figure 3 A threaded hole 18 is provided on the lower surface of the face difference gauge 16, and a threaded column 17 is threadedly connected to the inner wall of the threaded hole 18. By rotating the face difference gauge 16 forward or reversely, the threaded hole 18 can be gradually separated from the threaded column 17, thereby facilitating the face difference gauge 16 to be quickly removed or installed from the base 1. The bottom end of the threaded column 17 is fixedly connected to the upper surface of the lifting plate 15.

[0034] Working principle: When it is necessary to detect the burrs of the machined workpiece, align the threaded column 17 with the threaded hole 18 and rotate it forward until the face difference gauge 16 is fixed on the lifting plate 15. After adjusting the face difference gauge 16 to the specified value, place the machined workpiece on the surface of the turntable 4, pull the positioning piece 10 upward with one hand, the spring 11 will shrink, and the other hand will rotate the handle 6 forward. The threaded rod 7 will rotate and drive the moving block 8 to slide inside the groove 5 until the positioning piece 10 is above the machined workpiece. Release the positioning piece 10, and the elastic force of the spring 11 will allow the chassis of the positioning piece 10 to provide compression and positioning for the machined workpiece. Repeating the above steps in sequence can provide three-point positioning for the machined workpiece. According to the height of the machined workpiece, start the electric push rod 14, and the electric push rod 14 drives the lifting plate 15 to rise and fall, so that the face difference gauge 16 moves to the appropriate position, and manually push the guide seat 13 to slide on the guide rail 12 The face difference gauge 16 gradually approaches the machined part so that the face difference gauge 16 contacts the edge of the machined part. After the guide seat 13 cannot be pushed, the operator observes the size of the burr with the naked eye, increases the value of the face difference gauge 16 according to the size of the burr, and measures again until the face difference gauge 16 can barely pass through the edge of the sheet. At this time, the value displayed on the face difference gauge 16 is the value of the burr. After the face difference gauge 16 detects the single-sided edge of the machined part, it slides on the guide rail 12 away from the turntable 4 through the guide seat 13. The motor 3 is preset in advance by the PLC controller and can drive the turntable 4 to rotate ninety degrees when started. The above steps are repeated again to perform burr detection on the four sides of the machined part. When the machined part is a special-shaped part and its edge is larger than the four sides, the PLC controller is used to control the motor 3 to adjust the angle at which it drives the turntable 4 to rotate, thereby facilitating comprehensive burr detection for the machined part.
