Description

Technical Field

[0001] The utility model relates to the technical field of numerical control tools, in particular to a numerical control tool with an anti-slip mechanism. Background Art

[0002] With the rapid development of social production and science and technology, mechanical products are becoming more and more sophisticated and complex. CNC milling machines, also known as CNC milling machines, are CNC machine tools with strong processing functions. The rapidly developing machining centers and flexible machining units are all based on CNC milling machines and CNC boring machines. Both are inseparable from milling methods. CNC tools are tools used for cutting in mechanical manufacturing, also known as cutting tools. In a broad sense, cutting tools include both tools and grinding tools. Patent No. CN202223010575.0 announced a CNC milling machine with an anti-slip structure. The tool and tool clamping structure for CNC milling machines are connected by a card plate and a card slot opened in two mounting blocks, so that the tool can be firmly connected to the inside of the mounting block. The cooperation of the two-way threaded rod and the connecting seat facilitates the movement of the two mounting blocks. The cooperation of the limiting half ring and the fixed clamp ring makes the mounting block have a very stable mounting structure, and the operation is simple and convenient to install. However, when clamping and preventing the CNC tool from falling off, the staff needs to manually rotate the two-way threaded rod to control the operation of the mounting block, so as to clamp and prevent the CNC tool from falling off, which is not convenient enough to operate. For this reason, we propose a CNC tool with an anti-falling mechanism. Utility Model Content

[0006] By adopting the above technical solution, when the cutter body is mounted on the rotating drum at the bottom of the main shaft body, it is convenient to operate the controller by remote control, and the battery body on the surface of the ring seat is convenient to provide power support, and then the micro electric push rod on the surface of the semi-arc arm can be controlled to operate. When the micro electric push rod is in operation, the power output end is convenient to extend and pass through the sockets on the semi-arc arm and the outer periphery of the rotating drum, and then it is convenient to plug in with the sockets on the surface of the cutter body, so as to prevent the cutter body from falling off, and the whole process is automated and more convenient;

[0007] When the micro electric push rod needs to be maintained, it is only necessary to remove the screws between the two groups of semi-arc arms that are matched with the ring groove on the outer periphery of the lower drum, and since the two groups of semi-arc arms are hinged to each other between the ring seat, the two groups of semi-arc arms can be separated from each other and from the ring groove, and then the ring seat can be disassembled, which is convenient for maintenance or replacement of the micro electric push rod on the surface of the semi-arc arm, and the battery body on the surface of the ring seat can also be replaced, so that the micro electric push rod can continue to prevent the CNC tool from falling off.

The inner circumferential surface of the annular groove is provided with an arc groove that fits and connects with the arc strip, and there are multiple groups of arc grooves.

[0009] By adopting the above technical solution, the arc strip and the arc groove are connected in a fitting manner, which facilitates improving the tightness of the two groups of semi-arc arms and the annular groove after being connected in a fitting manner.

[0010] Specifically, rubber pads are bonded to opposite sides of the two groups of semi-arc arms.

[0011] By adopting the above technical solution, the rubber pad has certain anti-slip and protective properties, which is convenient for reducing scratches and damages caused by friction between the semi-arc arm and the inner wall of the ring seat.

[0012] Specifically, the outer circumferential surface of the drum is integrally constructed with a socket for connection, and the outer circumferential surface of the semi-arc arm is integrally constructed with a sleeve that is engaged and connected with the socket, and bolts that can be fastened are assembled between the socket and the sleeve, and there are multiple groups of bolts.

Since the two groups of semi-arc arms are hinged to each other with the ring seat respectively, the two groups of semi-arc arms can be separated from each other and from the ring groove. Then the ring seat can be disassembled, which is convenient for the maintenance or replacement of the micro electric push rod on the surface of the semi-arc arm. At the same time, the battery body on the surface of the ring seat can also be replaced, so that the micro electric push rod can continue to prevent the CNC tool from falling off.
