Description

Technical Field

[0001] The utility model relates to the technical field of milling cutters, in particular to a high-precision milling cutter device. Background Art

[0002] A milling cutter is a cutting tool used for milling, typically in materials such as metal, wood, and plastic. A milling cutter works by removing material through contact between a rotating cutting edge and the workpiece. Milling cutters are widely used in machining applications, including metalworking, mold making, the automotive industry, aerospace, electronics, woodworking, and plastics processing.

[0003] The guarantee of high-precision milling cutter cutting mainly depends on the tool material, tool geometry, machine tool accuracy, fixture design, etc. Among them, a strong and stable fixture can ensure that the workpiece does not move during the processing and that the milling cutter does not loosen during the processing, thereby improving the repeatability of the processing; however, the existing milling cutters are mostly fixed with bolts when installed. The number of fixing bolts is large, which is not only troublesome to install, but the threaded connection is also prone to loosening during long-term operation, resulting in insufficient cutting accuracy. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a high-precision milling cutter device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A moving mechanism, the moving mechanism is used to drive the first slider and the second slider to move synchronously, and the moving mechanism includes a screw;

[0008] The limiting structure is used to limit the rotation of the screw.

[0009] When the first slider and the second slider move toward each other, they drive the two first plug rods and the second plug rods to move toward each other until the first plug rod and the second plug rod are respectively extended from the two ends of the socket so that the first magnet and the second magnet contact and attract each other, thereby fixing the first plug rod and the second plug rod inside the socket, and fixing the top end of the milling cutter inside the tool chuck.

[0010] As a further technical solution of the present invention, a fixing groove is provided at the bottom of the tool chuck, and the fixing groove is adapted to the top end of the milling cutter.

[0011] As a further technical solution of the present invention, the other ends of the two cross bars are welded with limit plates, and the first slider and the second slider are slidably connected to the two cross bars respectively.

[0012] As a further technical solution of the present invention, two of the first insertion rods and the second insertion rods are provided, and the two first insertion rods and the second insertion rods are respectively and evenly distributed vertically on the inner sides of the first insertion rod and the second insertion rod.

[0013] As a further technical solution of the present invention, the two first insertion rods and the second insertion rod respectively pass through the opposite sides of the tool chuck and are slidably connected to the tool chuck. A hole is horizontally passed through the top of the milling cutter. There are two holes and they are adapted to the first insertion rod and the second insertion rod.

[0014] As a further technical solution of the present invention, the screw is horizontally rotatably connected to the outer side of the tool chuck, a moving block is sleeved on the outer side of the screw, and the moving block is connected to the screw through a thread. One side of the first slider and the second slider are both rotatably connected to a linkage rod, and the other ends of the two linkage rods are rotatably connected to the side of the moving block. A turntable is welded to one end of the screw, and a hand-held rod is horizontally welded to the outer periphery of the turntable.

[0015] The handheld rod is used to drive the turntable to rotate half a circle clockwise, and the turntable drives the screw to rotate clockwise, which drives the moving block to move outward on the screw. The moving block drives the first slider and the second slider to move toward each other through two linkage rods.

[0016] As a further technical solution of the present invention, the limiting structure includes a limiting rod, a threaded hole is opened on one side of the outside of the tool chuck, one end of the limiting rod and the threaded hole can be connected by threads, and the limiting rod can be abutted against the bottom of the handheld rod.

[0017] When the top end of the milling cutter is fixed inside the tool chuck, the front end of the limit rod is screwed into the threaded hole and fixed, and the limit rod abuts under the hand-held rod. The limit rod prevents the hand-held rod from driving the turntable to rotate counterclockwise, and prevents the screw from rotating counterclockwise, thereby preventing the first insertion rod and the second insertion rod from detaching from both ends of the socket. This not only makes the fixing step between the milling cutter and the tool chuck simpler and faster, but also makes the installation more stable, avoids loosening caused by threaded connection, and ensures cutting accuracy.

[0018] The beneficial effects of the utility model are: not only does it make the fixing step between the milling cutter and the tool chuck simpler and faster, but the installation is also more stable, thus avoiding loosening caused by threaded connection and ensuring cutting accuracy.
