[0003] To improve machining accuracy, CNC machine tools have extremely high requirements for flatness when machining workpieces. Currently, it is not convenient for staff to check the flatness of the CNC machine tool platform, resulting in poor performance of CNC machine tools. Summary of the Invention
[0004] The purpose of this invention is to provide an automatic testing device for CNC machine tools to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0019] Figure 1 shows a structural diagram of an automatic inspection device for CNC machine tools according to an embodiment of the present invention. The device includes a fixed frame 1 with a handle 11 on its surface. The fixed frame 1 has a box-like structure with an opening at its bottom. Rotating rods 2 are rotatably mounted at both ends of the fixed frame 1, with each end of the rotating rods 2 extending to the outside of the fixed frame 1 and fixedly mounted with a first roller 21. A bearing plate 3 is slidably mounted vertically within the inner cavity of the fixed frame 1. A second roller 31 is rotatably mounted on the bottom wall of the bearing plate 3. A positioning component 4, which cooperates with the bearing plate 3, is provided between the opposite side walls of the fixed frame 1. The positioning component 4 is used to apply a vertically downward thrust to the bearing plate 3. A detection mechanism 5 is provided on the surface of the bearing plate 3, comprising a writing component 51 and a surveying component 52. The writing component 51 is located on the surface of the bearing plate 3, and the surveying component 52 is located within the inner cavity of the fixed frame 1.
[0020] In use, the mounting bracket 1 is placed on the machine tool's work platform, and the mounting bracket 1 is pushed to move on the work platform surface. As the mounting bracket 1 moves, the positioning component 4 applies a pushing force to the support plate 3, ensuring that the second roller 31 at the bottom of the support plate 3 remains in contact with the work platform surface. While the support plate 3 moves, the writing component 51 and the surveying component 52 work together to automatically draw a horizontal line inside the mounting bracket 1. The undulations of the horizontal line allow for automatic detection of the work platform's flatness. Large undulations on the horizontal line indicate significant differences in the work platform's flatness, requiring adjustment.
[0021] As shown in Figures 1 and 3, in a preferred embodiment of the present invention, the positioning component 4 includes two sets of horizontal plates 41 respectively located on both sides of the support plate 3, which are fixedly installed on the opposite side walls of the fixing frame 1. The upper and lower sets of horizontal plates 41 are fixedly installed with vertical rods 42. A sliding block 43 is fixedly installed on the side wall of the support plate 3. The sliding block 43 is slidably connected to the vertical rod 42 in the vertical direction. A compression spring 44 is fixedly installed on the bottom wall of the upper horizontal plate 41. The compression spring 44 surrounds the outside of the vertical rod 42 and is connected to the sliding block 43.
[0022] In use, the compression spring 44 applies a pushing force to the sliding block 43, and the sliding block 43 drives the bearing plate 3 to move downward, thereby causing the second roller 31 to contact the working platform.
[0023] As shown in Figures 1 and 3, in a preferred embodiment of the present invention, the writing component 51 includes a mounting hole 511 through both ends on the surface of the support plate 3. A surveying pen 512 is detachably installed in the mounting hole 511, and a rubber pad that cooperates with the surveying pen 512 is provided in the mounting hole 511.
[0024] When in use, the fixed frame 1 moves on the surface of the work platform, causing the bearing plate 3 to move synchronously. The measuring pen 512 is installed in the mounting hole 511. When the fixed frame 1 and the bearing plate 3 move, the measuring pen 512 can draw a horizontal line in real time. The flatness of the work platform can be detected by the horizontal line.
[0025] As shown in Figures 1, 2, and 3, in a preferred embodiment of this utility model, the surveying component 52 includes a base plate 521 located outside the bearing plate 3, which is fixedly installed on the opposite side walls of the fixing frame 1. A fixing roller 522 is provided on the surface of the base plate 521, and a surveying paper roll 523 is provided on the surface of the fixing roller 522. Two sets of horizontal plates 525 distributed vertically opposite to each other are fixedly installed on the opposite side walls of the fixing frame 1. A rotating column 526 is rotatably installed between the two sets of horizontal plates 525. A take-up roller 524 is provided on the surface. The end of the surveying paper roll 523 away from the fixed roller 522 is connected to the take-up roller 524. A rotating column 527 is rotatably installed in the inner cavity of the fixed frame 1. A driven helical gear disk 528 is fixedly installed at the bottom of the rotating column 526. An active helical gear disk 529 that meshes with the driven helical gear disk 528 is fixedly installed on the surface of the rotating column 527. Synchronous disks 520 are fixedly installed on the surfaces of the rotating column 527 and the rotating rod 2, respectively. A synchronous belt 5210 is installed on both sets of synchronous disks 520.
[0026] When the fixed frame 1 moves, the rotating rod 2 rotates, which in turn drives the synchronous disk 520 to rotate. The two sets of synchronous disks 520 and the synchronous belt 5210 cooperate with each other to drive the rotating column 527 to rotate. The rotating column 527 drives the active helical gear disk 529 to rotate. The active helical gear disk 529 meshes with the driven helical gear disk 528 to drive the rotating column 526 to rotate. The rotating column 526 drives the take-up roller 524 to rotate, which in turn pulls the surveying paper roll 523 to move. The surveying pen 512 can automatically draw a horizontal line on the surface of the surveying paper roll 523.
[0027] As shown in Figures 1 and 3, in a preferred embodiment of the present invention, a bracket 6 is fixedly installed on the inner side wall of the fixing frame 1, and a pad 7 that cooperates with the surveying paper roll 523 is fixedly installed at the end of the bracket 6.
[0028] The working principle of this utility model is as follows: During use, the fixing frame 1 is placed on the machine tool's work platform, and the fixing frame 1 is pushed to move on the work platform surface. When the fixing frame 1 moves, the positioning component 4 applies a pushing force to the bearing plate 3, ensuring that the second roller 31 at the bottom of the bearing plate 3 is always in contact with the work platform surface. When the bearing plate 3 moves, the surveying pen 512 is installed in the mounting hole 511. When the fixing frame 1 moves, the rotating rod 2 rotates, thereby driving the synchronous disc 520 to rotate. The two sets of synchronous discs 520 and the synchronous belt 5210 cooperate to drive the rotating column 527 to rotate. The rotating column 527 drives the active helical gear disc 529 to rotate. The active helical gear disc 529 meshes with the driven helical gear disc 528, which can drive the rotating column 526 to rotate. The rotating column 526 drives the take-up roller 524 to rotate, thereby pulling the surveying paper roll 523 to move. The surveying pen 512 can automatically draw a horizontal line on the surface of the surveying paper roll 523. The undulation of the horizontal line can automatically detect the flatness of the work platform. When there are large undulations on the horizontal surface, it indicates that there are significant differences in the flatness of the work platform, and the work platform needs to be adjusted.
[0029] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
