Description

Technical Field

[0001] This invention relates to a milling cutter chamfering tool and its usage method. Background Technology

[0002] End mill chamfering is a common surface treatment method used to chamfer the tail of a workpiece. This process can improve the appearance quality, safety, and durability of the workpiece.

[0003] During the milling process, burrs and necking are prone to appear at the tail end of the milling cutter, which affects the cutting accuracy. To solve this problem, it is necessary to perform a chamfering process on the tail end of the milling cutter to increase its rigidity and prevent necking.

[0004] Traditional milling cutter chamfering relies on manual labor, with the operator holding the cutter and chamfering the annular area at the tail end. However, manual chamfering is inefficient, difficult to operate, and the machining quality is hard to guarantee depending on the operator. Therefore, a milling cutter chamfering tooling and its usage method are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a milling cutter chamfering tooling and its usage method to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a milling cutter chamfering fixture, comprising a tool holder connected to the spindle of a milling machine, one side of the tool holder being connected to a sleeve via a height adjustment assembly, and the inside of the sleeve being connected to a cutting tool for milling cutter chamfering via an angle adjustment assembly.

[0007] The process involves placing the milling cutter to be chamfered inside the sleeve, and adjusting the inclination angle and height of the cutter using the angle adjustment component and the height adjustment component, thereby adjusting the chamfering angle of the milling cutter.

[0008] Preferably, the sleeve is arc-shaped, and an arc-shaped groove for the rotation of the tool is provided on one side of the sleeve.

[0009] Preferably, the angle adjustment component includes a rotating shaft disposed inside an arc-shaped groove, a rotating gear connected to the outer periphery of the rotating shaft, a hexagonal bolt rod disposed on one side of the rotating shaft, a hexagonal bolt cylinder connected to the side of the rotating shaft closer to the hexagonal bolt rod, and one side of the hexagonal bolt cylinder connected to a polygonal bolt cap via a connecting rod.

[0010] Preferably, the rotating shaft has a hexagonal bolt groove on one side of the hexagonal bolt rod, and the hexagonal bolt groove and the hexagonal bolt cylinder are mutually matched;

[0011] The outer periphery of the polygonal cap has a groove for lifting, the top of the polygonal cap is connected to an adjustment knob, and one side of the polygonal cap is provided with a finger plate for indicating the rotation angle.

[0012] Preferably, one side of the sleeve has a polygonal groove for connecting the polygonal cap, and the outer periphery of the polygonal groove has scale markings for indicating the rotation angle of the polygonal cap.

[0013] Preferably, the back side of the cutting tool is provided with a semi-annular groove, and the interior of the semi-annular groove is provided with a rotating tooth groove that cooperates with the rotating gear.

[0014] Preferably, the height adjustment assembly includes a connecting plate disposed on one side of the sleeve, the connecting plate having an elastic groove inside, a guide post disposed inside the elastic groove, a positioning protrusion slidably connected to one side of the guide post, and a spring disposed on the outer periphery of the guide post on one side of the positioning protrusion to allow the positioning protrusion to move elastically within the elastic groove.

[0015] Preferably, a slide rail is connected to one side of the connecting plate, and a positioning groove for engaging with a positioning protrusion is provided inside the slide rail. A positioning cavity is provided on one side of the positioning groove, and a protrusion that cooperates with the positioning groove is connected inside the positioning cavity. The protrusion is connected to a protrusion located on one side of the slide rail.

[0016] A torsion plate is provided in the middle of the convex button, and the torsion plate is connected to a fixing plate through a shaft.

[0017] Preferably, the inner wall of the positioning cavity is provided with multiple sets of channels for the insertion of the fixing plate, and a fan-shaped fastening groove is provided below the channel, and the fastening groove is located below the positioning groove.

[0018] A method for using a milling cutter chamfering fixture includes the following steps:

[0019] Step A: Connect the tool holder to the milling machine spindle, press the cam on one side of the slide rail, and move the cam plate into the positioning groove. The cam plate presses the positioning cam, causing it to press the spring in the elastic groove. The spring is compressed by force, and the positioning cam moves into the elastic groove through the guide post, pushing the positioning cam out of the positioning groove and releasing the positioning of the connecting plate.

[0020] Step B: While pressing the button, the fixing plate moves along the channel into the slot. Then, the torsion plate located on one side of the button is rotated. The fixing plate is deflected in the slot through the shaft, thus restricting the position of the button.

[0021] Step C: Move the sleeve up or down to allow the connecting plate to move up and down in the slide rail. When it reaches the designated position, rotate the torsion plate in the opposite direction to make the connecting and fixing plate rotate in the opposite direction. At this time, the spring will stretch elastically and push the convex plate connecting and fixing plate out. The positioning convex button will move into the positioning groove through the guide post, and the position of the connecting plate will be fixed.

[0022] Step D: Pull the polygonal cap upwards so that the connecting rod connects the hexagonal plug cylinder out of the hexagonal plug groove and engages with the hexagonal plug rod. Then rotate the adjustment knob so that it drives the rotating shaft to rotate through the hexagonal plug cylinder. The rotating gear on the outer circumference of the rotating shaft engages with the rotating tooth groove of the tool, causing the connecting tool to deflect.

[0023] Step E: Observe the deflection angle between the finger plate and the scale on one side of the polygonal cap. When the angle of the tool deflection matches the preset chamfer angle of the milling cutter, press the polygonal cap into the polygonal groove to fix the polygonal cap and complete the setting of the chamfer angle of the milling cutter.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] This invention enables semi-automatic chamfering by incorporating height and angle adjustment components. Compared to traditional milling cutter chamfering, which requires manual operation, this fixture achieves semi-automatic chamfering of the milling cutter by adjusting the tool's tilt angle, height, and chamfering angle, greatly improving work efficiency.

[0026] With the help of angle adjustment components and height adjustment components, the tilt angle and height of the tool can be flexibly adjusted, thereby enabling precise control of the chamfer angle and ensuring consistent machining quality.

[0027] The tooling uses a connecting plate, slide rail, and convex plate structure, which allows the position of the sleeve and the tool to be easily adjusted and fixed by components such as fixing plate and convex button to ensure stability and reliability during the machining process.

[0028] The design of the multi-angled grooves and scale marks enables the tooling to display the rotation angle of the tool and the chamfer angle. The operator can intuitively observe and judge whether the preset chamfer requirements have been met, thus improving the accuracy of the operation.

[0029] In summary, the milling cutter chamfering tooling and its usage method have beneficial effects such as automated processing, precise control, convenient adjustment and fixation, and display indication. Attached Figure Description
