[0002] Traditional face milling tools and chamfering tools usually have fixed angles, so they can only process at specific angles. When the processing conditions are harsh or unconventional chamfers need to be processed, it is often necessary to customize specific tools or use complex CNC programming to achieve this. This not only increases manufacturing costs, but also prolongs the product trial production cycle, which is not conducive to improving production efficiency. Summary of the invention

The blade is fixed on the blade seat, and the blade seat is rotatably mounted on the base. When the blade seat rotates, the angle of the blade changes accordingly. The pressure plate is used to fix the blade seat to achieve angle locking after the blade angle adjustment is completed.

[0005] Furthermore, the back side of the blade seat is an arc-shaped surface, and a sliding pin and a rotating pin are provided at the bottom; an installation groove adapted to the blade seat is provided on the base, and a positioning pin hole and an arc-shaped sliding groove are provided at the bottom of the installation groove, and the arc-shaped sliding groove has the positioning pin hole as the center; the rotating pin is rotatably arranged in the positioning pin hole, and the sliding pin is slidably arranged in the arc-shaped sliding groove.

[0006] Further, the adjustable range of the blade angle is at least -45° to +45°.

[0007] Furthermore, a scale line indicating the angle of the blade is arranged on the arc surface on the back side of the blade seat.

[0008] Furthermore, the scale lines are set to 1 degree / grid.

[0009] Furthermore, the blade seat has a standard interface for installing the blade, and the blade is fixed to the blade seat by a blade bolt.

[0010] Furthermore, the blades include AP type and SD type cutting blades.

[0011] Furthermore, the pressure plate includes a positive pressure plate, which is used to fix the blade seat when the blade seat rotates in a positive direction, and the positive direction is a counterclockwise rotation direction.

[0012] Furthermore, the pressure plate also includes a negative pressure plate, which is used to fix the blade seat when the blade seat rotates in a negative direction, and the negative direction is a clockwise rotation direction.

[0013] Furthermore, the pressing plate is fixed on the base by means of mounting bolts.

[0014] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: the present invention has a simple structure, can adjust the angle of the blade according to actual processing requirements, and adapt to processing and chamfering requirements of different specifications. On the one hand, the cutting angle can be adjusted according to the product characteristics to adjust the distribution of the cutting force and improve the processing quality; on the other hand, the adjustable blade angle can be used to achieve flexible chamfering adjustment, reduce the types of tools, and have strong practicality. Compared with traditional chamfering tools, it not only simplifies the debugging work during the processing and reduces the production cost, but also improves the processing accuracy and efficiency, and shortens the trial production cycle of the product.

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] Attached Figures 1 to 4 The reference numerals in the figures are as follows:

[0021] 1, base; 1-1, positioning pin hole; 1-2, arc-shaped sliding groove; 2, sliding pin; 3, rotating pin; 4, blade seat; 4-1, scale line; 5, blade; 6, blade bolt; 7, positive pressure plate; 8, negative pressure plate; 9, mounting bolt.

[0022] like Figure 1 As shown, an embodiment of the present invention provides an angle-adjustable machining tool, comprising a base 1, a blade seat 4, a blade 5 and a pressing plate, wherein the base 1 is used to connect a tool handle, a machine tool or other machining equipment.

[0023] The blade seat 4 has a standard interface for installing the blade 5, and the blade 5 is fixed to the blade seat 4 by a blade bolt 6. The blade 5 includes AP (suitable for finishing of planes and bevels), SD (suitable for efficient cutting of difficult-to-cut materials) and other series of cutting blades.

[0024] Combination Figure 2The back side of the blade seat 4 is an arc-shaped surface, and the bottom is provided with a sliding pin 2 and a rotating pin 3. A mounting groove adapted to the blade seat 4 is provided on the base 1, and a positioning pin hole 1-1 and an arc-shaped sliding groove 1-2 are provided at the bottom of the mounting groove, and the arc-shaped sliding groove 1-2 takes the positioning pin hole 1-1 as the center of the circle. The rotating pin 3 is rotatably arranged in the positioning pin hole 1-1, and the sliding pin 2 is slidably arranged in the arc-shaped sliding groove 1-2. The blade seat 4 can rotate around the rotating pin 3 in the mounting groove, and the rotation range of the blade seat 4 is controlled by the arc-shaped sliding groove 1-2. When the blade seat 4 rotates, the angle of the blade 5 changes accordingly.

[0025] The curved surface on the back side of the blade seat 4 is provided with a scale line 4-1 indicating the blade angle, and the scale line 4-1 is set to 1 degree / grid. Based on the scale line 4-1, the operator can quickly adjust the angle of the blade 5 as needed. If a more precise angle needs to be adjusted, the angle can be calibrated with the help of a tool setting instrument. The adjustable range of the blade 5 angle is at least -45° to +45° to meet the needs of most processing.

[0026] The pressure plate is fixed to the base 1 by means of mounting bolts 9, and is used to fix the blade seat 4 to achieve angle locking after the blade 5 is adjusted in angle. In this embodiment, the pressure plate includes a positive pressure plate 7 and a negative pressure plate 8, wherein the positive pressure plate 7 is used to fix the blade seat 4 when the blade seat 4 rotates in the positive direction, and the positive direction is the counterclockwise rotation direction, such as Figure 3 The negative pressure plate 8 is used to fix the blade seat 4 when the blade seat 4 rotates in the negative direction, and the negative direction is the clockwise rotation direction, as shown in FIG. Figure 4 shown.

[0027] During specific use, the user can replace different types of blades 5 according to processing requirements, or configure multiple blade seats 4 (for example, 4, 6 or more), install different blades 5 on each blade seat 4 to form a modular structure, and then directly perform modular replacement.

[0028] The present invention can adjust the SD, AP and other series cutting blades at a certain angle according to actual use requirements, so as to adjust the cutting force direction and chamfer angle during milling, which can greatly improve the chamfering processing efficiency and quality.
