[0002] Positioning fixtures on CNC machine tool worktables are typically designed to ensure accurate and repeatable positioning of workpieces during machining. The design and manufacture of positioning fixtures fall under the category of mechanical design, which involves the design, machining, assembly, and testing of mechanical parts.

[0003] Traditional CNC machine tool table positioning fixtures are usually designed as separate movable table designs. With this design, the table usually needs to be moved out of the machine tool, then loaded with workpieces, and then moved back into the machine tool. This method wastes a lot of working time and reduces work efficiency.

[0004] Therefore, those skilled in the art have provided a positioning fixture for a CNC machine tool table to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a positioning fixture for CNC machine tool worktables. This fixture features a main slide groove at the top center of the positioning plate, a secondary slide groove at one end of the main slide groove, and a work plate that slides to both ends of the two secondary slide grooves. Both work plates can slide to the main slide groove. This structural design enables the exchange of worktables, solving the problem that traditional worktable positioning fixtures typically require removing the worktable from the machine tool, loading the workpiece, and then re-removing it, resulting in wasted time and reduced efficiency.

[0007] A positioning fixture for a CNC machine tool worktable includes a positioning plate. A main slide groove is formed at the center of the top of the positioning plate. A secondary slide groove is formed at one end of the main slide groove. Slider blocks are slidably arranged at both ends of the secondary slide groove. A work plate is fixedly arranged at the top of each of the two sliders. A main limit block is integrally formed at both ends of each of the two sliders. A secondary limit block is integrally formed at both ends of each of the two sliders. A positioning hole is formed at the center of one side of each of the two work plates.

[0008] The above technical solution involves a main slide groove at the top center of the positioning plate, a secondary slide groove at one end of the main slide groove, and a working plate that slides at both ends of the two secondary slide grooves. Both working plates can slide to the main slide groove. This structural design enables the exchange of worktables and solves the problem that the positioning fixtures for worktables usually require the worktable to be moved out of the machine tool, then loaded with workpieces, and then moved back into the machine tool, which wastes a lot of working time and reduces work efficiency.

[0009] Furthermore, a storage groove and a movable groove are sequentially opened in the middle of one side of the positioning plate. A positioning rod is slidably arranged inside the movable groove. A spring is sleeved inside the movable groove at the outer end of the positioning rod. A positioning post is fixedly arranged at one end of the positioning rod. One end of the positioning post is designed to be arc-shaped.

[0010] With the above technical solution, when the working plate is moved towards the center of the positioning plate, one side of the working plate will contact the arc end of the positioning post and compress the positioning post into the receiving groove. When the arc end of the positioning post moves to the positioning hole in the center of the working plate, the spring rebound force will cause the positioning post to be inserted into the positioning post. At this time, the position of the working plate is restricted, and the slider at the bottom of the working plate at this position is aligned with the main slide groove, which makes it convenient for the working plate to be pushed into the main slide groove.

[0011] Furthermore, a drive motor is installed on one side of the positioning plate, and a double-ended lead screw is installed at the output end of the drive motor. Both ends of the double-ended lead screw are threaded with limiting plates.

[0012] With the above technical solution, a drive motor is installed on one side of the positioning plate, and a double-ended lead screw is installed at the output end of the drive motor. Limiting plates are threaded on both ends of the double-ended lead screw. By cooperating with the drive motor and the double-ended lead screw, the two limiting plates are controlled to move synchronously in opposite directions, thereby facilitating the position restriction of the working plate that has moved into the main slide groove.

[0013] Furthermore, a human-machine interface is installed on one side of the positioning plate, and the human-machine interface is electrically connected to the drive motor;

[0014] The above technical solution allows for the installation of a human-machine interface on one side of the positioning plate. The human-machine interface is electrically connected to the drive motor, thus facilitating the control of the drive motor.

[0015] Furthermore, the outer side of the positioning plate is integrally provided with multiple mounting seats, and each mounting seat has a mounting hole in the middle.

[0016] Through the above technical solution, multiple mounting seats are integrally provided on the outer side of the positioning plate, and each mounting seat has a mounting hole in the middle to facilitate the installation and fixing of the positioning plate.

[0017] Furthermore, fixing grooves are provided on both sides of the top of the positioning plate;

[0018] The above technical solution provides fixing grooves on both sides of the top of the positioning plate to facilitate the movement of the limiting plate and to restrict the movement position of the limiting plate.

[0019] Furthermore, a pull ring is integrally provided at the end of the positioning rod away from the positioning post;

[0020] The above technical solution provides an integral pull ring at the end of the positioning rod away from the positioning post, which facilitates the movement of the positioning rod.
