Description

Technical Field

[0001] This application relates to the field of CNC machine tools, and in particular to a pneumatic positioning mechanism for CNC machine tool workpieces. Background Technology

[0002] A CNC machine tool is an automated machine tool equipped with a program control system. The control system logically processes the program specified by control codes or other symbolic instructions, decodes it into coded numbers, and inputs it into the CNC device via an information carrier. After processing, the CNC device sends control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings. CNC machine tools often use pneumatic positioning mechanisms to position workpieces. In a conventional pneumatic positioning mechanism, after fixing the mounting base inside the machine tool, a pneumatic cylinder is installed on the top of the mounting base. A limit block is installed at one end of the pneumatic cylinder, and a fixed seat is connected to the top of the mounting base. The fixed seat and the limit block facilitate the installation of the workpiece inside the machine tool.

[0003] Regarding the aforementioned technologies, the inventors believe that when conventional pneumatic positioning mechanisms process workpieces, since some workpieces require processing at multiple angles, conventional pneumatic positioning mechanisms often use moving blocks to limit the workpieces. This results in the need to loosen the pneumatic positioning mechanism and then adjust the workpiece when rotating it, thereby increasing the amount of operation required by the pneumatic positioning mechanism.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the inconvenience of conventional pneumatic positioning mechanisms when rotating workpieces, this application provides a pneumatic positioning mechanism for CNC machine tool workpieces.

[0006] The technical solution of the pneumatic positioning mechanism for CNC machine tool workpieces provided in this application is as follows:

[0007] A pneumatic positioning mechanism for CNC machine tool workpieces includes a mounting base and a motor. A pneumatic cylinder is fixedly mounted on the top of the mounting base, and a limit block is fixedly connected to one end of the pneumatic cylinder. A fixed base is fixedly mounted on the top of the mounting base. A connecting gear is fixedly connected to the output end of the motor. A rotating gear meshes with the top of the connecting gear. A rotating disk is fixedly mounted on one end of the rotating gear. The top of the motor is fixedly connected to one end of the pneumatic cylinder. One end of the rotating gear is rotatably mounted to one end of the pneumatic cylinder. One end of the rotating disk is rotatably connected to one end of the limit block.

[0008] Preferably, a slider is fixedly installed at the bottom end of the limiting block, a limiting rod is slidably connected to the inner wall of the slider, and a groove adapted to the slider is opened at the top of the mounting base, and the inner wall of the groove is fixedly installed to the surface of the limiting rod.

[0009] Preferably, the rotating disk is a rubber disk, and the surface of the rotating disk is provided with a plurality of auxiliary grooves, which are evenly distributed on the surface of the rotating disk.

[0010] Preferably, a limiting plate is rotatably mounted on one end of the fixed base, a fixing block is fixedly connected to one end of the limiting plate, one end of the fixing block is rotatably mounted to the surface of the fixed base, and a locking block is engaged at the bottom end of the fixing block.

[0011] Preferably, a first electric push rod is fixedly installed at the bottom end of the card block, one end of the first electric push rod is fixedly connected to one end of the mounting base, and the center of the first electric push rod and the center of the card block are on the same straight line.

[0012] Preferably, a connecting plate is fixedly installed on the surface of the fixing base, and the surface of the connecting plate is provided with a plurality of scale grooves, which are arranged in a circular array with the center of the connecting plate as the axis.

[0013] Preferably, both sides of the mounting base are rotatably connected to a limiting frame, and a second electric push rod is rotatably mounted on the limiting frame. One end of the second electric push rod is rotatably connected to the inner wall of the mounting base.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. By mounting a motor on the surface of a limit block, a rotating gear is installed at the motor's output end via a connecting gear. One end of the rotating gear is connected to a rotating disk, allowing the rotating gear to rotate via the connecting gear after the motor starts. This controls the angle of the rotating disk relative to the workpiece, thus facilitating the control of the workpiece's rotation angle. A slider is installed at the bottom of the limit block, with a limit rod slidably connected to its inner wall. The surface of the limit rod is slidably installed with a groove in the mounting base, allowing the slider to slide on the limit rod surface, thereby improving the stability of the limit block during movement. The rotating disk is a rubber disk, and one end of the rotating disk has several auxiliary grooves. The rubber material of the rotating disk enhances friction, which, combined with the auxiliary grooves, improves the fixing effect of the rotating disk on the workpiece. Compared to existing technologies, this significantly improves the convenience of the pneumatic positioning mechanism.

[0016] 2. Alternatively, a fixing block can be installed on the surface of a limiting plate at one end of the fixing base. A locking block is attached to the bottom of the fixing block to secure it to the fixing block, thus fixing the angle of the limiting plate and effectively improving the workpiece fixation effect of the limiting plate and the fixing plate. A first electric push rod is fixedly connected to the bottom of the locking block, with one end connected to the surface of the mounting base. This allows for adjustment of the locking block's length and control of its up-and-down movement, making it more convenient to use. A connecting plate is fixedly connected to the surface of the fixing base, with several graduated grooves on its surface for easy observation of the workpiece's rotation angle. Limiting frames are rotatably connected to both sides of the mounting base, with a second electric push rod rotatably connected to the bottom of each limiting frame. This allows for control of the limiting frame's rotation, thereby clamping the adjusted workpiece surface and effectively improving workpiece stability. This also enhances the overall effectiveness of the device. Attached Figure Description

A fixed base 4 is connected to the top of the mounting base 1. The fixed base 4 and the limit block 3 facilitate the installation of the workpiece inside the machine tool. A motor 6 is installed on the surface of the limit block 3. A rotating gear 8 is installed at the output end of the motor 6 via a connecting gear 7. A rotating disk 5 is connected to one end of the rotating gear 8. After the motor 6 is started, the rotating gear 8 is driven to rotate via the connecting gear 7. The rotating disk 5 is controlled to adjust the angle of the workpiece, thereby facilitating the control of the workpiece's rotation angle and effectively improving the convenience of the pneumatic positioning mechanism.

[0024] Reference Figure 2 The bottom end of the limiting block 3 is equipped with a slider 9, and the inner wall of the slider 9 is slidably connected to the limiting rod 10. The surface of the limiting rod 10 is slidably installed with the sliding groove 11 in the mounting base 1. By sliding the slider 9 on the surface of the limiting rod 10, the stability of the limiting block 3 when moving is improved. The rotating disk 5 is a rubber disk, and one end of the rotating disk 5 is provided with several auxiliary grooves 12. By utilizing the rubber material of the rotating disk 5, which has the characteristic of increasing friction, the auxiliary grooves 12 are used to improve the fixing effect of the rotating disk 5 on the workpiece.

[0025] Reference Figure 3 - Figure 4 The fixing block 13 is installed on the surface of the limiting plate 16 at one end of the fixing base 4. The bottom end of the fixing block 13 is engaged with the locking block 14. The locking block 14 engages with the fixing block 13, thereby fixing the angle of the limiting plate 16 and effectively improving the fixing effect of the limiting plate 16 and the fixing plate on the workpiece. The bottom end of the locking block 14 is fixedly connected to the first electric push rod 15. One end of the first electric push rod 15 is connected to the surface of the mounting base 1. The locking block 14 can be moved up and down by adjusting its own length, which is more convenient to use. The surface of the fixing base 4 is fixedly connected to the connecting plate 16. The surface of the connecting plate 16 is provided with several scale grooves 17. The scale grooves 17 make it easy to observe the rotation angle of the workpiece. The two sides of the mounting base 1 are rotatably connected to the limiting frame 18. The bottom end of the limiting frame 18 is rotatably connected to the second electric push rod 19. The second electric push rod 19 controls the rotation of the limiting frame 18, thereby clamping the surface of the workpiece after adjustment by the limiting frame 18, which effectively improves the stability of the workpiece.

[0026] The implementation principle of a pneumatic positioning mechanism for CNC machine tool workpieces in this embodiment is as follows: A motor 6 is mounted on the surface of a limiting block 3.

A slider 9 is mounted on the bottom end of the limiting block 3. A limiting rod 10 is slidably connected to the inner wall of the slider 9. The surface of the limiting rod 10 is slidably mounted with a sliding groove 11 in the mounting base 1, so that the slider 9 can slide on the surface of the limiting rod 10, thereby improving the stability of the limiting block 3 when it moves. The rotating disk 5 is a rubber disk, and several auxiliary grooves 12 are opened on one end of the rotating disk 5, so that the rubber material of the rotating disk 5 has the characteristic of increasing friction, and the auxiliary grooves 12 are used to improve the fixing effect of the rotating disk 5 on the workpiece.

[0027] Alternatively, the fixing block 13 can be installed on the surface of the limiting plate 16 at one end of the fixing base 4. The bottom end of the fixing block 13 is engaged with a locking block 14, so that the locking block 14 can engage with the fixing block 13 to fix the angle of the limiting plate 16, effectively improving the fixing effect of the limiting plate 16 and the fixing plate on the workpiece. The bottom end of the locking block 14 is fixedly connected to a first electric push rod 15, one end of which is connected to the surface of the mounting base 1, so that the locking block 14 can be moved up and down after adjusting its own length. It is more convenient to use. The surface of the fixed base 4 is fixedly connected to the connecting plate 16. The surface of the connecting plate 16 is provided with several scale grooves 17, so that the rotation angle of the workpiece can be easily observed with the help of the scale grooves 17. The two sides of the mounting base 1 are rotatably connected to the limit frame 18. The bottom end of the limit frame 18 is rotatably connected to the second electric push rod 19, so that the limit frame 18 can be controlled to rotate with the help of the second electric push rod 19, thereby clamping the surface of the workpiece after adjustment with the help of the limit frame 18, effectively improving the stability of the workpiece.
