Description

Technical Field

[0001] The utility model relates to the technical field of special processing of titanium alloy structural parts, in particular to a six-directional special processing bracket. Background Art

[0002] Titanium alloy is an alloy composed of titanium and other metal elements with a variety of excellent physical and chemical properties. Titanium alloy structural parts cast from titanium alloy are widely used in many fields due to their excellent performance.

[0003] The existing titanium alloy structural parts have an outer dimension of φ239mm and a height of 173mm. They are bracket structures cast from cast titanium ZTC4 and serve as supports for other components. They are large in size and irregular in shape. The six directions of the part contain multiple connector holes, and most of the connector holes are square right-angle holes, requiring root cleaning on all sides. Due to the limitation of the radius of the machining tool, the connector openings have rounded corners on all sides after being processed in the machining center. In addition, the hardness of titanium alloy is relatively high (HRC40-45), and the rounded corners are thick, making manual processing impossible. Therefore, special electric spark machining is adopted. However, when positioning the part, a vise is required for six clamping and repeated alignment, which greatly consumes processing time and cannot be mass-produced.

[0004] In response to the above problems, it is urgent to carry out innovative design based on the original six-way special processing bracket structure. Utility Model Content

[0007] Preferably, the bottom plate is designed as a hollow aluminum plate, and the upper and lower surfaces of the bottom plate are smooth and flat; this structure ensures the horizontal accuracy of the titanium alloy structural parts during positioning through the smooth flatness.

[0008] Preferably, the bracket body is designed with two groups of positioning pin holes on the plane; this structure can achieve precise positioning of the structural member in two directions, namely, the left side and the right side, by changing the positioning angle, thus meeting the processing direction requirements.

[0009] Preferably, the side plates are designed as hollowed-out aluminum plates, and the upper and lower planes of the side plates are smooth flatness; this structure ensures the horizontal accuracy during the positioning of the structural components through the smooth flatness of the side plates.

[0010] Preferably, the top plate is designed as a hollowed-out aluminum plate, and the upper and lower planes of the top plate are smooth flatness; this structure ensures the horizontal accuracy during the positioning of the structural components through the smooth flatness of the top plate.

[0011] Preferably, both the bottom plate and the side plates, and between the side plates and the top plate are connected by two groups of screw holes and pins; this structure ensures the perpendicularity of the connection between the plates by connecting the bottom plate and the side plates, and between the side plates and the top plate through two groups of screw holes and pins.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The six-way bracket cleverly utilizes the existing positioning holes of the structural components in design, ensuring the positioning accuracy of the part positions;

[0014] 2. The six-way bracket realizes all-direction requirements for chamfering of the structural components by changing the contact surface between the bracket and the workbench of the processing equipment and changing the position of the positioning pins;
