The former pursues the accuracy and surface quality limits of machining, while the latter includes the automation of product design, manufacturing and management. It is not only an important means to quickly respond to market demand, improve productivity and improve working conditions, but also an effective measure to ensure product quality. The two are closely related. Many precision and ultra-precision machining rely on automation technology to achieve the expected indicators, and many manufacturing automations rely on precision machining to be accurately and reliably realized.

[0003] In the process of precision manufacturing, shaft parts need to be polished. Currently, two ends of the shaft parts are generally clamped by two positioning blocks, and the positioning blocks are driven to rotate by a driving device to rotate the shaft parts, and then the rotating shaft parts are polished by a polishing block. However, the existing processing device is not convenient for detecting the polishing conditions of various parts of the shaft parts. When the polishing block is tilted, the shaft parts cannot be polished evenly, resulting in deviations in the outer wall dimensions of the shaft parts. Therefore, it is necessary to detect the polishing conditions of various parts of the shaft parts.

[0004] Therefore, those skilled in the art have proposed a processing device for precision manufacturing to solve the problems raised in the above background. Utility Model Content

The polishing conditions of different parts of the shaft parts can be detected by cooperating with the distance sensor 23 through multiple contact components, and the polishing data of different parts can be compared to detect the polishing conditions of various positions of the shaft parts in real time.

[0019] The adjusting component includes a fixed seat 5 installed on the base 1, a bidirectional screw 6 is rotatably arranged on the fixed seat 5, both sides of the bidirectional screw 6 are threadedly connected to a movable frame 7 that is slidably connected to the fixed seat 5, the movable frame 7 is fixedly connected to a fixed frame 9, and a first motor 8 connected to the bidirectional screw 6 is installed on the outer wall of the fixed seat 5.

[0020] The grinding component comprises a first cylinder 3 installed at the bottom of the bracket 2 , and the first cylinder 3 is fixedly connected to the grinding block 4 .

[0021] The pushing component includes a second cylinder 13 installed on the side frame 12, the second cylinder 13 is fixedly connected to the movable frame 14, the movable frame 14 is fixedly connected to the L-shaped test plate 16, and a guide rod 15 slidably connected to the movable frame 14 is installed on the side frame 12.

[0022] The contact component includes a test column 18 that is slidably connected to a test frame 17. A mounting plate 19 is installed at one end of the test column 18 that is close to the L-shaped test plate 16. A spring 20 that is sleeved on the test column 18 is provided between the mounting plate 19 and the test frame 17. A limit block 21 is installed on the test column 18. A roller 22 is rotatably installed on one end of the test column 18 that is away from the mounting plate 19. A distance sensor 23 is installed on the mounting plate 19.

[0023] The working principle of the utility model is: when in use, the shaft parts are placed between the two clamping blocks 10, and the first motor 8 is started. The first motor 8 drives the bidirectional screw 6 to rotate, so that the two movable frames 7 are close to each other, so that the two clamping blocks 10 are close to each other, and then the two ends of the shaft parts are clamped and fixed, and the second motor 11 is started to drive the clamping blocks 10 to rotate, so that the clamped shaft parts are rotated; then the second cylinder 13 is started, and the second cylinder 13 pushes the movable frame 14 to approach the shaft parts, so that the roller 22 at the end of the test column 18 contacts the outer wall of the shaft parts, and starts to collect the distance between the mounting plate 19 and the end of the L-shaped test plate 16 through the distance sensor 23, and finally, by starting the first cylinder 3, the grinding block 4 is driven to descend, and through grinding Block 4 is used to grind shaft parts. As the grinding progresses, the diameter of the shaft parts will gradually become smaller. In the process of grinding the shaft parts by the grinding block 4, under the action of the spring 20, the mounting plate 19 will be subjected to tension, so that the roller 22 is always in contact with the outer wall of the shaft parts. The distance sensors 23 on multiple mounting plates 19 will detect the distance from the end of the L-shaped test plate 16, and the data detected by the multiple distance sensors 23 will be compared. When the data detected by the multiple distance sensors 23 have a large deviation, it means that the grinding conditions of various parts of the shaft parts are different. At this time, the outer wall of the shaft parts is no longer cylindrical due to the inconsistent grinding conditions of various parts, which means that the grinding block 4 cannot grind the shaft parts evenly, and it is necessary to stop grinding and check the grinding block 4.

[0024] The utility model adjusts the distance between the two clamping blocks 10 through the arranged adjusting component, clamps and fixes the shaft parts through the clamping blocks 10, grinds the parts through the grinding component, and pushes the L-shaped test plate 16 through the pushing component, so that the contact component contacts the shaft parts. The grinding conditions of different parts of the shaft parts can be detected by cooperating with the distance sensor 23 through multiple contact components, and the grinding conditions of various positions of the shaft parts can be detected in real time by comparing the grinding data of different parts.
