[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4 This utility model provides an embodiment of a positioning and detection device for CNC machining, including a circular base 1 and positioning components; three sets of slidable positioning components are arranged around the top of the circular base 1 for adjustment and positioning according to the size of the workpiece. Each positioning component includes a rectangular slide rail 201, a first rectangular threaded sleeve 202 fixedly installed at the lower end of the rectangular slide rail 201, a fixed limiting plate 206 fixedly installed at the connection between the rectangular slide rail 201 and the first rectangular threaded sleeve 202, and a linear engraving on one side of the rectangular slide rail 201. The ruler 207 has a first threaded rod 203 passing through the middle of the first rectangular threaded sleeve 202. The inner side of the rectangular slide rail 201 has a second rectangular slide groove 205. The inner side of the second rectangular slide groove 205 of the rectangular slide rail 201 has a second threaded rod 208 vertically arranged. The outer side of the second threaded rod 208 is fitted with a second rectangular threaded sleeve 209. A movable limiting plate 210 is fixedly installed on one side of the second rectangular threaded sleeve 209. Multiple sets of arc-shaped grooves are horizontally opened above the fixed limiting plate 206 and below the movable limiting plate 210.

[0022] Please see Figure 2 In this embodiment, a first rectangular groove 101 is provided on the top of the circular base 1 corresponding to the positioning component. The first rectangular groove 101 facilitates the sliding adjustment of the positioning component, improving the flexibility of the positioning detection device. An installation hole 102 is provided on the top of the circular base 1, intersecting with the first rectangular groove 101. The installation hole 102 facilitates the assembly of the circular base 1 with the worktable. An installation screw 103 is inserted through the middle of the installation hole 102 on the circular base 1. By passing the installation screw 103 through the installation hole 102, the circular base 1 is positioned and connected to the worktable, which facilitates the placement of the workpiece to be processed.

[0023] Please see Figures 3-4In this embodiment, the first threaded rod 203 is obliquely arranged along the first rectangular slide groove 101. The first rectangular threaded sleeve 202 drives the rectangular slide rail 201 to make preliminary movement and adjustment along the first rectangular slide groove 101, so that the workpiece can be positioned and limited along the arc groove on the fixed limiting plate 206. A first motor 204 is installed at one end of the first threaded rod 203. According to the size of the workpiece, the first threaded rod 203 is rotated by the drive of the first motor 204. A second motor 211 is installed at the upper end of the second threaded rod 208. The second threaded rod 208 is rotated by the drive of the second motor 211, so that the second rectangular threaded sleeve 209 drives the movable limiting plate 210 to move downward along the second rectangular slide groove 205.

[0024] During operation, the mounting screw 103 is first passed through the mounting hole 102 to position and connect the circular base 1 to the worktable. After assembly, depending on the size of the workpiece, the first threaded rod 203 is rotated by the first motor 204, causing the first rectangular threaded sleeve 202 to move and adjust the rectangular slide rail 201 along the first rectangular slide groove 101. This allows the workpiece to be positioned along the arc groove on the fixed limiting plate 206. Then, the second threaded rod 208 is rotated by the second motor 211, causing the second rectangular threaded sleeve 209 to move the movable limiting plate 210 downward along the second rectangular slide groove 205. The arc groove on the movable limiting plate 210, in conjunction with the arc groove on the fixed limiting plate 206, positions the workpiece. Finally, the workpiece is inspected using a scale 207 to avoid errors.

[0025] Through the above steps, the positioning component makes initial sliding adjustments on the circular base 1 according to the size of the workpiece. Then, the workpiece is placed on the positioning component, and the positioning component makes further adjustments to position the workpiece. The workpiece is then detected by the scale 207 on the positioning component. Through the adjustable positioning structure, it can adapt to workpieces of different shapes, sizes and materials, thereby meeting diverse processing needs. It can also reduce errors and deviations in the processing process, improve processing quality and consistency, and thus improve production efficiency. This solves the problem that most existing positioning and detection devices are used in a unidirectional fixed manner. Since different workpieces have different sizes, if the device is not easy to adjust, it may affect the processing accuracy and reduce production efficiency.
