Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a fixture for CNC equipment maintenance. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for construction or inspection. It is also called a clamp. In a broad sense, any device used to quickly, conveniently and safely install a workpiece in any step of the process can be called a fixture. In CNC machine tools, fixtures are usually used to hold the workpiece and rotate it for maintenance.

[0003] However, in the process of using existing fixtures, because the end of the fixture is provided with a groove for placing the workpiece, a large amount of debris inevitably falls into the groove during maintenance or cutting and trimming. If the debris inside the groove is not cleaned, it will affect the placement of the workpiece in the groove next time, causing the center axis of the workpiece to be not in the same straight line as the fixture. Cleaning requires manual or external air gun, which is a cumbersome process. Therefore, we propose a fixture for CNC equipment maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a fixture for CNC equipment maintenance, so as to solve the problem mentioned in the background art that if the debris inside the groove is not cleaned, it will affect the placement of the workpiece in the groove next time, resulting in the workpiece's center axis not being in the same straight line as the fixture.

A cleaning tube is installed at the top of the hose, and four sets of brackets are fixedly connected to the side of the cleaning tube. The brackets have slots inside, and a rotating shaft is rotatably connected to the surface of the chuck body. Limiting brackets are symmetrically installed on both sides of the rotating shaft.

[0010] The flexible hose is designed to be flexible, and a limit ring is provided at the connection between the connecting shaft and the air inlet.

[0011] The cross-sectional area of ​​the slot is the same as that of the limit frame, and the limit frame and the slot do not overlap in the working state.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1 to 6 This utility model provides a technical solution: a fixture for CNC equipment maintenance, including a chuck body 1, a circular groove for placing workpieces is provided in the center of the chuck body 1, a working component 2 is installed on the side of the chuck body 1, the working component 2 can clamp the side of multiple workpieces, including a conversion component 3, the conversion component 3 is installed on the side of the chuck body 1, and the conversion component 3 is connected to the side of the machine tool as a whole.

[0026] The cleaning component 4 is connected to the side of the conversion component 3. The cleaning component 4 can blow air into the circular groove inside the chuck body 1. The conversion component 3 includes a fixed plate 7. The bottom of the fixed plate 7 is attached to the side of the machine tool. The fixed plate 7 is set as a ring structure.

[0027] The surface of the fixed plate 7 is equipped with connecting teeth 8, and the interior of the fixed plate 7 is provided with connecting holes 9. The interior of the connecting holes 9 is connected to the side of the machine tool by bolts. The connecting holes 9 are connected to the CNC machine tool itself. When in use, the chuck body 1 clamps the workpiece, which causes the transmission teeth 10 connected to the side of the chuck body 1 to rotate on the surface of the connecting teeth 8, thereby enabling the transmission teeth 10 to rotate and realizing the drive conversion process of the rotation force of the chuck body 1.

[0028] The outer edge of the connecting tooth 8 is rotatably connected to the side of the transmission tooth 10. The back of the transmission tooth 10 is fixedly connected to one end of the connecting shaft 11. A fan blade 12 is fixedly connected to the side of the connecting shaft 11. A housing 13 is sleeved on the outer edge of the connecting shaft 11. One end of the housing 13 is fixedly connected to the side of the chuck body 1. An air inlet 14 is opened on the side of the housing 13. A ventilation pipe 15 is fixedly connected to the side of the housing 13. When the transmission tooth 10 rotates, it will drive the connected connecting shaft 11 and the fan blade 12 to rotate together. The fan blade 12 can draw the outside air of the housing 13 into the interior of the housing 13 through the air inlet 14 and guide it through the ventilation pipe 15, and then transmit it to the interior of the cleaning component 4.

[0029] Example 2

[0030] The cleaning component 4 includes a hose 16, the bottom end of which is fixedly connected to the top end of the ventilation pipe 15. A cleaning pipe 17 is installed at the top end of the hose 16. Four sets of brackets 18 are fixedly connected to the side of the cleaning pipe 17. The brackets 18 have slots 19 inside. A rotating shaft 20 is rotatably connected to the surface of the chuck body 1. Limiting frames 21 are symmetrically installed on both sides of the rotating shaft 20. When air is injected into the cleaning pipe 17 through the ventilation pipe 15 and the hose 16, it will be discharged from the cleaning pipe 17 near the circular groove of the chuck body 1, thereby cleaning the inside of the circular groove of the chuck body 1 by blowing air. This solves the problem of manual cleaning and makes it easier for personnel to observe the workpiece clamped inside the circular groove. At the same time, in order to prevent the gas thrust from affecting the position of the cleaning pipe 17, the limiting frame 21 on the side of the rotating shaft 20 is rotated so that it does not overlap with the slot 19. The limiting frame 21 is used to lock the cleaning pipes 17 connected to the brackets 18, thereby fixing the position of the cleaning pipe 17.

[0031] The flexible hose 16 is designed to bend, and a limit ring is provided at the connection between the connecting shaft 11 and the air inlet 14. After the flexible hose 16 is bent, the adjustment knob 5 can be exposed, which is convenient for personnel to adjust the adjustment knob 5.

[0032] The cross-sectional area of ​​the slot 19 is the same as that of the limit frame 21. The limit frame 21 and the slot 19 do not overlap in the working state. When the limit frame 21 and the slot 19 overlap, the bracket 18 can be fitted into the side of the rotating shaft 20. When they do not overlap, the limit frame 21 can fix the bracket 18.

[0033] The working component 2 includes an adjustment knob 5. The adjustment knob 5 is rotatably connected to the side of the chuck body 1. The movable jaw 6 is slidably connected to the end of the chuck body 1. The movable jaw 6 can clamp workpieces such as automobile and transportation metal workpieces and building material workpieces. The movable jaw 6 can slide inside the chuck body 1 and abut against the sides of the workpiece, thereby achieving the function of fixing the workpiece.

[0034] The cleaning pipe 17 is designed with a right-angle structure, and the air outlet of the cleaning pipe 17 is located at the lower end of the right-angle structure. When in use, the air outlet of the cleaning pipe 17 is aligned with the circular groove in the center of the disc body 1.
