Description

Technical Field

[0001] This utility model relates to the field of fixtures, and in particular to a five-axis CNC cutting, trimming and positioning fixture for automotive center console panels. Background Technology

[0002] The center console is an important component of a car's interior. It is typically located between the driver and passenger seats, or at the front of the center armrest. This panel integrates controllers and displays for various electrical devices within the vehicle, serving as an information and control center.

[0003] After the automotive center console panel is formed, it typically needs to be aligned and trimmed using a five-axis CNC machine tool. Before trimming, the panel needs to be positioned using a positioning fixture. Existing positioning fixtures mainly consist of a bracket, a lower fixed mold, and an upper fixed cover. The lower fixed mold is fixed to the top of the bracket; the upper fixed cover is detachably mounted on the lower fixed mold. During trimming, the center console panel is clamped between the lower fixed mold and the upper fixed cover. This type of positioning fixture, due to its mechanical clamping, is prone to panel deformation (above ±0.1mm), has insufficient positioning accuracy, affecting the quality of the cut edges, and lacks clamping stability, easily vibrating during high-speed cutting, leading to burrs or chipping during trimming. Therefore, it is necessary to improve the current positioning fixture. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a five-axis CNC cutting and trimming positioning fixture for automotive center console panels, which can effectively solve the problems of insufficient positioning accuracy and stability of existing positioning fixtures.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A five-axis CNC cutting, trimming, and positioning fixture for automotive center console panels includes a bracket, a lower fixed mold, an upper fixed cover, and a soft fixing device. The lower fixed mold is fixed to the top of the bracket. The upper fixed cover is detachably mounted on the lower fixed mold. The soft fixing device is disposed between the lower fixed mold and the upper fixed cover.

[0007] Preferably, the lower fixing mold is provided with a positioning pin, and the upper fixing cover is positioned in conjunction with the positioning pin.

[0008] Preferably, there are two positioning pins.

[0009] Preferably, the soft fixing device is a soft rubber cover plate.

[0010] Preferably, the lower fixing mold is provided with a knob groove device, and the upper and lower surfaces of the upper fixing cover are provided with through holes, and a fastening knob passes through the through holes from top to bottom and is installed and connected to the knob groove device.

[0011] Preferably, the bracket includes a lower positioning plate, multiple support plates, and an upper positioning plate; the lower positioning plate is horizontally arranged, the multiple support plates are vertically fixed on the lower positioning plate, the upper positioning plate is horizontally arranged and located above the lower positioning plate, the upper positioning plate is fixed to the top of the multiple support plates, and the lower fixing mold is fixed on the upper positioning plate.

[0012] Preferably, the upper positioning plate is provided with a first handle on both the left and right sides.

[0013] Preferably, the top of the upper fixed cover is provided with a second handle.

[0014] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0015] By placing a soft fixing device between the lower fixed mold and the upper fixed cover, the soft fixing device can press against the car's center console panel, achieving flexible positioning of the center console panel. This allows the fixture to automatically adapt to panels with different curvatures (R5mm~R800mm), reducing clamping deformation (controlled to ≤0.05mm), effectively improving positioning accuracy, and greatly improving the quality of the cutting edge. At the same time, the clamping stability is better, and it is less prone to vibration during high-speed cutting, preventing edge trimming burrs or chipping, thus facilitating cutting and trimming.
