As shown in Figures 1 and 2, there are support bolts (3c) on the lower side plate (34).

The use of tooling of the present utility model during product processing comprises the following steps:

Step 1. Install the base on the A-axis

Put the circular boss (1a) on the base into the inner hole of the A-axis table of the four-axis vertical machining center. The outer diameter φA of the general base body should be slightly smaller than the table surface of the A-axis table of the four-axis vertical machining center Diameter; pass the screw through the open sinking groove (1b) on the base, into the threaded hole on the A-axis workbench and tighten, so as to realize the fastening of the base on the A-axis workbench. After fastening, the base can effectively rotate with the A-axis, and the possible radial runout and axial inclination between the base and the A-axis during processing are effectively eliminated.

Step 2. Installation of the support base on the base

The supporting seat (2) is positioned on the base (1) by positioning pins, and then fastened by screws.

Step 3. Install the side panels on the support base

Connect the front side plate (31), the rear side plate (32), the upper side plate (33) and the lower side plate (34) to the support base (2) by screws respectively—if the size of the side plate is larger, For example, the front side plate (31) and the rear side plate (32) are inconvenient to be fastened directly, and can be positioned through the positioning pin hole (3b) first; the top plate (4) is connected to the front side plate (31) and the rear side by screws. The plate (32) is securely connected.

Step 4. Installation of products to be processed

Concrete product (5) among Fig. 1 is rolling mill guide guard support arm. During installation, the position of the product in the Y-axis direction (the Y-axis direction is the vertical paper direction in the schematic diagram) is fixed by the front side plate (31) and the rear side plate (32), and the upper side plate (33) and the lower side plate ( 34) Fix the position of the product in the Z-axis direction (the Z-axis direction is perpendicular to the A-axis direction in the schematic diagram), and fix the product in the X-axis direction (the X-axis direction is parallel in the schematic diagram) through the top plate (4) and support bolts (3c). A-axis direction). So far, the product to be processed is positioned and installed in the tooling of the four-axis vertical machining center of the present utility model and fastened. At this time, it is possible to start to process each surface (including the inclined surface) of the product successively. For holes and grooves, remove the product after processing, install another product, and continue processing after tightening until all the holes and grooves on all sides (including slopes) around the product to be processed are completely processed.

The tooling of the utility model has a fundamental change with the existing four-axis vertical machining center tooling: the existing tooling is to combine the length direction of the product (the Z-axis direction in the present invention) with the four-axis vertical machining center. The axis A of the center is placed in parallel, and only holes in the up and down directions are processed on the four-axis vertical machining center; the tooling designed in the present invention is to place the thickness direction of the product (that is, the X-axis direction in the present invention) It is parallel to the A axis of the four-axis vertical machining center, so that after the rotation and positioning of the A-axis of the four-axis vertical machining center is locked, all the surfaces, holes and grooves around the product (including the inclined surface) are smooth. It can be used for the purpose of processing on a four-axis vertical machining center.

The specifications of the side plates, top plates and support seats in the tooling of the utility model can be simply changed according to different products, such as changing the position and quantity of U-shaped grooves on the front and rear side plates. The top plate, side plate and support seat of different specifications can be matched with the base of the same specification, so that a series of thin products with close dimensions and similar geometric shapes can be processed. In addition, by changing the size of the base, the tooling of the utility model can be applied to the processing of various thin products. Therefore, according to the idea of the present invention, there will be changes in the specific implementation and application range, and such changes should also fall into the protection scope of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
