Description

Technical Field

[0001] This utility model relates to the field of worktable technology, and in particular to a CNC machine tool worktable with a quickly adjustable fixture. Background Technology

[0002] As is well known, CNC machine tools are highly automated and precise machine tools. They use a Computer Numerical Control (CNC) system to control the movement and machining process, enabling precise execution of various machining tasks on metal and non-metal parts, such as milling, turning, drilling, and grinding. CNC machine tools control the relative movement of the tool and workpiece through pre-programmed instructions, achieving high precision, high efficiency, and mass production. They are widely used in aerospace, automotive manufacturing, mold processing, and many other fields. The worktable is typically a crucial component of a CNC machine tool, used to support and fix the workpiece to be machined. The stability and precision of the worktable directly affect the workpiece's positioning accuracy and machining quality during the machining process.

[0003] However, traditional CNC machine tool worktables typically use fixed or single-type fixtures, which are difficult to adapt to different workpieces quickly, limiting flexibility. Furthermore, each time a workpiece is changed, the fixture usually needs to be changed, which can take a lot of time and affect production efficiency. Therefore, technological improvements are urgently needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a CNC machine tool worktable with a rapidly adjustable fixture. When in use, the CNC machine tool worktable is activated by starting a servo motor to drive the rotating rod to rotate, which in turn drives the transmission wheel and synchronous belt to rotate. This, in turn, drives the threaded rods on both sides to rotate. The rotation of the threaded rods causes the threaded sleeve block and the mounting box to move closer together, thereby enabling the workpiece to be quickly clamped and fixed according to its required length.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A CNC machine tool worktable with a quick-adjustable fixture includes a worktable with a storage cavity inside. Two mounting plates are fixedly connected to both sides of the upper surface of the worktable. A rotating rod is rotatably connected to the middle of the inner wall of one side of the storage cavity. The other side of the rotating rod passes through the worktable to the outside of the worktable. Threaded rods are rotatably connected to the outer walls of the mounting plates adjacent to the edge of the worktable. The adjacent sides of the threaded rods pass through the two mounting plates near the center of the worktable and are fitted with threaded sleeve blocks.

[0007] An installation box is fixedly connected to the outer wall of the adjacent side of the threaded sleeve. A storage groove is opened on the outer wall of the adjacent side of the installation box. A bidirectional threaded rod is rotatably connected to the front and rear ends of the inner wall of the storage groove. Clamping pads are sleeved on both ends of the bidirectional threaded rod. The outer wall of the adjacent side of the clamping pads penetrates the storage groove to the outside of the installation box.

[0008] Compared with existing CNC machine tool worktables, this CNC machine tool worktable, through the above technical solution, drives the bidirectional threaded rod to rotate by rotating the rotating ring, while simultaneously driving the clamping pad to move in the opposite direction, thereby fixing the width of the workpiece as required, and has higher practical performance.

[0009] Furthermore, a PLC control panel is provided on one side of the outer wall at the front end of the workbench;

[0010] The above technical solution allows for electrical connection between the PLC control panel and the servo motor, facilitating control of its switching.

[0011] Furthermore, support legs are fixedly connected to the four corners of the lower surface of the workbench;

[0012] The above technical solution uses supporting legs to improve overall stability.

[0013] Furthermore, a protective shell is fixedly connected to the middle of the outer wall on the other side of the workbench, and a servo motor is fixedly connected to the inner wall on the other side of the protective shell. The output end of the servo motor is fixedly connected to the other side of the outer wall of the rotating rod.

[0014] The above technical solution allows the servo motor to easily drive the rotating rod to rotate.

[0015] Furthermore, transmission wheels are respectively fitted on both sides of the outer wall of the rotating rod and on the side of the outer wall of the threaded rod away from the center of the worktable, and synchronous belts are fitted on the outer walls of the transmission wheels;

[0016] With the above technical solution, a synchronous belt is fitted on the outer wall of each transmission wheel to facilitate the rotation of the threaded rods on both sides.

[0017] Furthermore, sliding grooves are provided on both sides of the top surface of the storage cavity, and a limit block is fixedly connected to one side of the raw material workbench at the lower end of the outer wall of the threaded sleeve block;

[0018] The above technical solution facilitates improved fit through the use of limit blocks and sliding grooves.

[0019] Furthermore, all the limiting blocks are slidably connected inside the slide groove;

[0020] The above technical solution allows the limiting blocks to slide within the groove, facilitating the lateral movement of the threaded sleeve block by limiting its movement.

[0021] Furthermore, each of the front ends of the outer wall of the mounting box is provided with a rotating ring, and the rear ends of the rotating rings penetrate the mounting box into the interior of the storage slot and are fixedly connected to the outer wall of the front end of the bidirectional threaded rod.

[0022] The above technical solution allows the rotating ring to easily drive the bidirectional threaded rod to rotate.

[0023] This utility model has the following beneficial effects:

[0024] 1. The present invention proposes a CNC machine tool worktable with a quick-adjustable fixture. Compared with existing CNC machine tool worktables, when this CNC machine tool worktable is in use, the servo motor drives the rotating rod to rotate, which in turn drives the transmission wheel and the synchronous belt to rotate. This drives the threaded rods on both sides to rotate. The rotation of the threaded rods drives the threaded sleeve block and the mounting box to move closer together, thereby enabling the workpiece to be quickly clamped and fixed according to the required length.

[0025] 2. The CNC machine tool worktable with a quick-adjustable fixture proposed in this utility model, compared with the existing CNC machine tool worktable, when in use, drives the bidirectional threaded rod to rotate by rotating the rotating ring, and at the same time drives the clamping pad to move in opposite directions, so as to fix the width of the workpiece according to the required, and has higher practical performance.

The adjacent side of the threaded rod 24 passes through the two mounting plates 13 near the center of the worktable 1 and is fitted with threaded sleeve blocks 27.

[0036] An installation box 3 is fixedly connected to the outer wall of the adjacent side of the threaded sleeve 27.

The outer wall of the clamping pad 33 on the adjacent side passes through the storage groove 31 to the outside of the installation box 3.

[0037] Compared with existing CNC machine tool worktables, this CNC machine tool worktable, when in use, drives the bidirectional threaded rod 32 to rotate by rotating the rotating ring 34, while simultaneously driving the clamping pad 33 to move in the opposite direction, thereby fixing the width of the workpiece as required, and has higher practical performance.

[0038] Reference Figure 1 , Figure 2 and Figure 5A PLC control panel 11 is installed on one side of the outer wall of the front end of the workbench 1.
