Multi-adaptive fast loading attached air-cooled dust removal equipment

Multi-adaptive fast loading attached air-cooled dust removal equipment, comprising:

• a spindle clamping mechanism,
• a link mechanism,
• a bearing connecting mechanism,
• an axial telescopic mechanism, and
• a dust treatment mechanism;
• the spindle clamping mechanism has a bilaterally symmetrical structure, wherein the machine tool spindle housing is clamped and fixed by a left clamping ring and a right clamping ring through bolts and nuts;
• and the left clamping ring and the right clamping ring have a half-cylindrical thin wall structure, and pin holes are formed in the middle of the left clamping ring and the right clamping ring;
• the link mechanism has a bilaterally symmetrical structure and comprises two groups of links;
• and a lower link and an upper link are connected through bolts and nuts, the upper end of the upper link is connected with a pin which is inserted into the pin hole to be connected with the spindle clamping mechanism, and the lower end of the lower link is connected with an ear of a telescopic inner ring through bolts and nuts;
• the bearing connecting mechanism is a mechanism that connects the tool holder and the axial telescopic mechanism, and comprises an inner expansion sleeve component, a rolling bearing and an outer expansion sleeve component, wherein the inner expansion sleeve component is sheathed on the tool holder, the rolling bearing is sheathed on the inner expansion sleeve component, the outer expansion sleeve component is sheathed on the rolling bearing, the telescopic inner ring of the axial telescopic mechanism is sheathed on the outer expansion sleeve component, and the above parts are connected by interference fit;
• the axial telescopic mechanism is a mechanism that matches with a drill bit to realize axial feeding movement during drilling, and comprises the telescopic inner ring, a telescoping outer ring, a spring, and an outer ring bottom cover;
• the main body of the telescopic inner ring has a stepped cylindrical structure with a thick upper part and a thin lower part, the center of the telescopic inner ring is a through hole to accommodate the tool, the upper inside wall is matched with the outer cylindrical surface of the outer expansion sleeve component, and the lower outside wall has a plurality of raised sliders distributed annularly;
• the main body of the telescoping outer ring has a stepped cylindrical structure with a thin upper part and a thick lower part, the center has a hollow structure to accommodate the axial movement of the tool, the inner wall is provided with a Z-shaped slide, and the plurality of raised sliders and the Z-shaped slide are used to realize the telescopic function of the axial telescopic mechanism;
• the inner wall of the telescoping outer ring near the bottom has a concave airway structure, a suction hole is formed in the outer wall, the airway is communicated with the suction hole, and the spring is sheathed between the telescopic inner ring and the telescoping outer ring;
• and a through hole that can accommodate the diameter of a tool is formed in the center of the outer ring bottom cover which is connected with the telescoping outer ring through threads;
• the dust treatment mechanism comprises a dust suction pipe, a negative pressure vacuum cleaner and a dust collection device;
• and the dust suction pipe is connected with the suction hole of the outer ring, one end of the negative pressure vacuum cleaner is connected with the dust suction pipe, and the other end is connected with the dust collection device;
• the negative pressure vacuum cleaner forms a negative pressure cavity between the telescopic inner ring and the telescoping outer ring by suction to export chips generated during processing and other impurities through the dust suction pipe into the collection device for storage;
• and the cooling of a cutting area and the tool is realized by air flow;
• during milling, the telescoping outer ring used in drilling is replaced, an outer ring part for milling is used, the telescoping outer ring with a slide on the inner wall having a L-shaped structure.
