Description

Technical Field

[0001] This utility model belongs to the field of fixture technology, and more specifically relates to a multifunctional CNC fixture for side pushing and downward pressing. Background Technology

[0002] When CNC machining parts, they need to be completely positioned and fixed using fixtures. The fixing method typically involves using cylinders, hydraulic cylinders, etc., for clamping. The clamping position corresponds to the support or positioning surface of the part, which can create stable action and reaction forces on both sides of the part. However, for parts with internal cavities (such as...),... Figure 3 As shown, when the clamping, supporting, and positioning positions are all placed on the outside of the part, the part will deform due to the lack of support inside the part, which will affect the machining accuracy and the yield of the finished product.

[0006] Furthermore, the side pressure mechanism includes a side pressure cylinder and a side pressure plate, and the positioning support block is provided with the side top corresponding to the side pressure plate.

[0007] Furthermore, the pressing mechanism includes a pressing cylinder and a pressing plate, the pressing plate corresponding to a top support block.

[0008] Furthermore, the drive mechanism includes a drive cylinder and a wedge block located on the base, and the top support block and the wedge block are in contact through a wedge-shaped surface.

[0009] Furthermore, positioning strips are provided on the three sides of the first positioning area.

[0010] Furthermore, a protective shell is provided on the base, and the protective shell has openings corresponding to the first positioning area and the second positioning area.

[0011] Compared with the prior art, the utility model discloses the beneficial effects are: when positioning the part, the part is placed on the first positioning area, and the side pressure cylinder first pushes the part to make the part move towards the positioning support block until the part is preliminarily fixed through the cooperation of the side pressing plate and the positioning support block, then the driving cylinder is started to make the top support block rise, and the part is completely fixed in cooperation with the lower pressing plate, finally the part is drilled through the drilling mechanism, and since the inner cavity of the part has support when processing, the part will not be deformed when being pressed, thereby improving the part processing quality.
