[0002] With the development of industrial technology, CNC machine tools have become an important tool for high-precision machining. In the process of CNC machine tool machining, accurate measurement of workpiece dimensions is crucial to ensure machining quality and efficiency. At present, there are many workpiece measurement solutions on the market, among which the most common is the use of contact measuring devices, such as micrometers and calipers. However, these traditional contact measuring devices have obvious disadvantages: they need to directly contact the workpiece during the measurement process, which can easily cause scratches or damage on the surface of the workpiece. Not only is the efficiency low, but it is also easily affected by human errors, resulting in the inability to guarantee machining accuracy; in addition, traditional measurement structures are often separated from CNC machine tools, requiring additional handling and positioning steps, which increases the complexity of operation and the risk of errors; with the development of non-contact measurement technology, although some non-contact measurement equipment such as laser rangefinders and visual measurement systems are gradually used in workpiece measurement, their high cost and complex operation limit their popularization and application.

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a CNC machine tool measurement structure. Figure 1-Figure 3 , including a mounting frame 1, a group of connecting plates 3 are welded to the outer walls of both sides of the mounting frame 1, and a plurality of through holes are equidistantly opened on the surface of the connecting plates 3 to facilitate the installation and fixation of the mounting frame 1, a pillar 13 is rotatably installed on one side of the inner wall of the mounting frame 1, and a turning handle 2 is rotatably installed on the top of the mounting frame 1, one end of the turning handle 2 extends into the mounting frame 1 and is fixedly connected to the pillar 13, and a sliding rod 17 is provided on one side of the pillar 13, and the sliding rod 17 is rotatably connected to the inner wall of the pillar 13, and a gear 15 is fixed to the middle part of the outer wall of the pillar 13, and a gear 2 16 is fixed to the middle part of the outer wall of the sliding rod 17, so when the turning handle 2 is adjusted, the pillar 13 can be driven to rotate, and then the gear 15 and the gear 2 16 are meshed and connected, driving the sliding rod 17 to rotate synchronously.

[0020] like Figure 2 As shown, a positioning plate 17 is provided on the pillar 13, and a positioning plate 2 8 is provided at the bottom of the positioning plate 17. The outer walls at both ends of the pillar 13 are provided with threads 14. The positioning plates 17 and 2 8 are symmetrically arranged. The outer walls of the ends of the positioning plates 17 and 2 8 that are away from each other are welded with supporting slides 6. The supporting slides 6 are adapted to the threads 14, and the positioning plates 17 and 2 8 are arranged in a semi-arc shape. When the pillar 13 rotates, the supporting slides 6 will adapt to the threads 14, thereby pushing the positioning plates 17 and 2 8 to approach each other.

[0021] In addition, a measuring base 4 is fixedly installed on the outer wall of the bottom end of the positioning plate 2 8, and a scale bar 12 is provided on the side wall of the measuring base 4. The length of the workpiece can be measured by the measuring base 4, and a bracket 9 for support is slidably installed on the upper part of the measuring base 4. The bracket 9 has a supporting effect on the bottom of the workpiece, especially for a cylindrical workpiece, and its bottom can be lifted up, and a measuring ruler 18 is fixedly connected to one end of the positioning plate 1 7, and a movable block 5 is fixed to the side wall of the positioning plate 2 8;

[0022] The movable block 5 is slidably connected to the measuring ruler 18. When the positioning plate 1 7 moves downward, the measuring ruler 18 will cooperate with the movable block 5 and a pointer 19 is fixed on the movable block 5. At this time, the diameter width of the workpiece can be conveniently observed through the indicating scale of the pointer 19. A supporting bracket 10 is fixedly connected at the center of the inner wall of the positioning plate 1 7 and the positioning plate 2 8. A pulley 11 is rotatably installed inside the supporting bracket 10. The contact between the pulley 11 and the workpiece can reduce the sliding resistance and improve the measurement efficiency.

[0023] The implementation principle of a CNC machine tool measuring structure in an embodiment of the present application is as follows: when in use, the connecting plate 3 is fixed to the feed port of the CNC machine tool by bolts, thereby completing the installation of the mounting frame 1, and then the workpiece can be placed on the supporting bracket 10 in the positioning plate 2 8, and at the same time, the two ends of the workpiece are close to the bracket 9 to ensure its bottom supporting force. As the workpiece moves and contacts with the pulley 11, the sliding resistance can be reduced. Then, the rotating handle 2 is rotated to drive the pillar 13 to rotate, and then the engagement of gear 15 and gear 2 16 will drive the slide bar 17 to rotate synchronously. At this time, the supporting slide plate 6 will adapt to the thread 14, so as to drive the positioning plate 1 7 and the positioning plate 2 8 to slide outside the pillar 13 and the slide bar 17 and approach each other. At this time, the measuring ruler 18 cooperates to slide in the movable block 5, and the diameter distance of the workpiece can be measured according to the indication scale of the pointer 19, and the length distance of the workpiece can be measured through the scale bar 12. The overall structure is compact and easy to operate.
