The invention belongs to the field of hard rock cutting pick production equipment, and relates to a vacuum welding device for hard rock cutting pick production and a welding technology, and the vacuum welding device comprises a welding equipment main body used for welding a hard rock cutting pick; the moving unit is used for driving the tooth part of the hard rock cutting tooth to be in butt joint with the column part; the adapting unit is used for clamping and adapting to the concave-convex shape of the tooth surface of the hard rock cutting tooth; the preheating unit is used for performing rotary friction preheating on the tooth part and the column part of the hard rock cutting tooth fixed by the adaptive unit before welding and performing smooth treatment on the tooth part and the column part of the hard rock cutting tooth after welding, so that the adaptive flexible holding of the hard rock cutting tooth with a complex irregular tooth surface is realized through the adaptive unit; according to the positioning device, the positioning pins can be independently buffered and finely adjusted according to the tooth surface morphology, so that surface damage or microscopic crack initiation of a workpiece caused by stress concentration is effectively avoided while global uniform pressure application and extremely high clamping stability are ensured, and a crucial basic condition is provided for subsequent high-precision welding.

The invention discloses a deburring and polishing device and method for the edge of a special-shaped tooth groove of a rotating part, and belongs to the technical field of deburring and polishing. The bearing movement unit is mounted on the basic frame unit and is used for clamping a workpiece and driving the workpiece to perform rotary and inclined multi-axis movement; the machining execution unit is mounted on the basic frame unit and comprises a first polishing execution unit and a second polishing execution unit which are symmetrically arranged relative to the workpiece machining station on the bearing movement unit; the first polishing execution unit and the second polishing execution unit drive the tail end polishers to move on multiple spatial degrees of freedom so as to adjust the poses of the tail end polishers relative to the upper surface and the lower surface of the workpiece, and therefore the edges of the special-shaped tooth grooves in the upper end face and the lower end face of the workpiece are synchronously polished. The requirement for automatic polishing of a special-shaped tooth groove edge complex structure is met, and the stability, continuity and machining quality of the machining process are improved.

According to the medium-high cobalt gradient hard alloy material provided by the invention, a gradient structure is formed in situ by calcining raw materials, the surface layer part of the gradient hard alloy material does not contain a brittle Ti cubic phase and a Zr-containing cubic phase, the gradient hard alloy material has high toughness, the subsurface layer part contains the Ti-containing cubic phase, the interior contains the Ti-containing cubic phase and the Zr-containing cubic phase, and the hardness and the plastic deformation resistance are high; and the plastic deformation requirement and the hardness requirement of the dental bur under the contact collision action with high-hardness enamel on the surface of irregular teeth in the use process can be met.

This invention discloses a layered, self-adjusting bionic tooth clamping device, specifically designed to address irregular tooth shapes. The device comprises four parts: a rotating base module, a layered support module, a double-slide module, and a self-adjusting clamping module. Through clamping force, the layered support module, double-slide module, and self-adjusting clamping module automatically adapt to the irregular shape of the tooth, ensuring a tight fit and providing a stable fixation effect. The clamping and fixing base provides robust support, ensuring the stability and reliability of the device during use. This device is simple in design, easy to install and adjust, and can significantly improve the accuracy and stability of tooth fixation.
