[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1

[0021] like Figures 1 to 5 As shown, a specific embodiment of the special fixture for milling grooves of automotive control panel buttons with outward expansion grooves according to this utility model includes:

[0022] Lower clamp 1: Lower clamp 1 is fixedly installed on the milling machine. A groove 5 is provided on the right side of the upper surface of lower clamp 1. A workpiece placement groove 10 is provided in the groove 5. The automotive button workpiece 8 is assembled in the workpiece placement groove 10. The groove 5 facilitates the removal of the workpiece, and the workpiece placement groove 10 can better place the automotive button workpiece 8. Threaded connection holes 3 are provided on the right side of lower clamp 1 and upper clamp 2. The threaded connection holes 3 are used to assemble hinges, so that upper clamp 2 can be flipped relative to lower clamp 1, which facilitates the placement and removal of the workpiece.

[0023] Upper clamp 2: Located above the workpiece placement slot 10, the upper clamp 2 has a waist-shaped through slot 6, which is used by a milling machine to mill the automotive button workpiece 8. The upper opening of the waist-shaped through slot 6 is set as an outwardly expanding slot 7, the depth of which is half the depth of the waist-shaped through slot 6, and the angle between the outwardly expanding slot 7 and the horizontal plane is 30 degrees. This design can prevent the milling cutter from hitting the upper clamp 2. The bottom surface of the upper clamp 2 has an arc-shaped workpiece slot 9, which is set corresponding to the side boss 11 for clamping and fixing the automotive button workpiece 8. Since the automotive button workpiece 8 is relatively high, by combining the groove 5, the arc-shaped workpiece slot 9 and the workpiece placement slot 10 to place the workpiece, the overall height of the clamp can be reduced and the stability of the clamp can be improved.

[0024] Clamping handle 4: A clamping handle 4 is fixedly installed on the left side of the upper surface of the lower clamp 1. The clamping handle 4 is used to clamp the lower clamp 1 and the upper clamp 2 to fix the automotive button workpiece 8.

[0025] Automotive button workpiece 8: includes a side boss 11 integrally formed on the side and a light-blocking groove 12 machined on the bottom surface of the inner cavity by a milling machine;

[0026] In this embodiment, six workpiece placement slots 10 are provided, and they are arranged in two rows at equal intervals; two waist-shaped through slots 6 are provided corresponding to the two rows of placement slots. This design allows for the simultaneous milling of multiple automotive button workpieces 8, thereby improving production efficiency.

[0027] The working principle of this utility model is as follows: The upper clamp 2 is flipped open relative to the lower clamp 1 by means of a hinge. The automotive button workpiece 8 is placed into the workpiece placement slot 10 in the groove 5 of the lower clamp 1. The upper clamp 2 is flipped to a position that fits with the lower clamp 1 by means of a hinge. The clamping handle 4 is operated to clamp the lower clamp 1 and the upper clamp 2. After the workpiece is clamped, the milling equipment is started. The milling equipment extends through the waist-shaped through slot 6 of the upper clamp 2 to mill the bottom surface of the inner cavity of the automotive button workpiece 8 to mill the light-blocking groove 12.
