Description

Rapid knife exchanging mechanism and tool magazine thereof

Technical field

the utility model relates to a kind of Rapid knife exchanging mechanism and tool magazine, especially a kind of Rapid knife exchanging mechanism and tool magazine boring milling equipment.

Background technology

at present the rapid changing knife of brill milling equipment is on the market all adopt pulling claw tension blind rivet to carry out tool changing, and this structure tool changing is effective, and application is also extensive, and machining center on the market substantially all adopts this structure at present; But this complicated structure, manufacturing cost is high, is thus difficult to popularize at the equipment of economic class.

Summary of the invention

it is simple that the purpose of this utility model is to provide a kind of structure, the Rapid knife exchanging mechanism of low cost of manufacture and tool magazine.

in order to reach above-mentioned goal of the invention, the scheme that the utility model adopts is: the hole taper of the central shaft installation handle of a knife of main axle unit is designed to Small Taper structure, and make it connect good rigidly, cone angle is between 2 degree to 12 degree; In the bigger diameter end radial direction of main axle unit central shaft taper hole, elastic pressed piece is installed, the Excircle machining at the corresponding elastic pressed piece place of handle of a knife has locating slot or hole, when making elastic pressed piece push down locating slot or the hole of handle of a knife, handle of a knife has burst power be adjacent to the conical surface, thus preventing handle of a knife in machining, conical surface laminating is separated; The front end face of main axle unit central shaft is provided with alignment pin or block, and handle of a knife is processed with locating hole or groove to this alignment pin or block.

ensure to connect rigidity with the cone match of main axle unit central shaft by handle of a knife during work, ensure the transmission of turning power energetically by alignment pin or block, ensure the laminating all the time of the conical surface of handle of a knife and main axle unit central shaft in processing by elastic pressed piece; Elastic pressed piece is arranged on the bigger diameter end of main axle unit central shaft taper hole, can shorten the length of handle of a knife, and due to diameter large, can install elastic component also can be larger more, and elastic force is just larger, also facilitates the later stage to the replacing of elastic pressed piece and maintenance in addition in front end.This structure is simple, is easy to manufacture, and is economic desirable tool changing scheme of boring milling equipment.

conveniently automatic tool changer, the utility model adopts tool changing magazine tool structure to be: swaging clamp pawl is U-shaped structure, and it can directly snap in the draw-in groove of handle of a knife; Swaging clamp pawl is provided with compressive resilience part on the axial direction of relative main unit front end, makes it elasticity can force two cone match of handle of a knife and main axle unit central shaft when filling cutter; Swaging clamp pawl is provided with compressive resilience locating part on the axial opposed direction of relative main unit front end, thus make it when tool magazine put into by cutter, its axial screens is constant, and at Song Daoshi, compressive resilience locating part can hold swaging clamp pawl, thus block handle of a knife, allow handle of a knife be separated with the central shaft of main axle unit; Swaging clamp pawl is provided with alignment pin, limits its planar movement, thus make it only can resilient movement up and down; Swaging clamp pawl is arranged in the scope that slide unit is movable to below main axle unit axis side by side, and it is made up of a row or multi-row.During tool changing, main axle unit is located, and slide unit moves and makes empty calorie cutter pawl block the handle of a knife be contained on main axle unit, and then main shaft moves, handle of a knife is separated with main axle unit; Then slide unit moves immediately below new cutter to main axle unit again, and main axle unit moves down, and the compressive resilience part under compression swaging clamp pawl, make two cone match of handle of a knife and main axle unit central shaft, slide unit moves and allows swaging clamp pawl leave handle of a knife.This structure of this structure is simple, is easy to manufacture, and is the economic desirable-auto tool changing tool magazine boring milling equipment.

Detailed description of the invention

with reference to shown in Fig. 1, the hole taper that the central shaft 1 of the present embodiment main axle unit installs handle of a knife 2 is designed to 8 degree; In the bigger diameter end radial direction of main axle unit central shaft taper hole, the elastic pressed piece be made up of compression spring 4, steel ball 3, screw 5 is installed, this elastic pressed piece circumference is provided with 5 groups side by side, and the Excircle machining outside the corresponding elastic pressed piece of handle of a knife 2 has an annular positioning groove 6; The front end face of main axle unit central shaft 1 is provided with alignment pin 7, and handle of a knife is processed with locating hole 8 to this alignment pin.

with reference to shown in Fig. 2, in order to better ensure the repetitive positioning accuracy of handle of a knife 2 in the present embodiment, and reliably blow when ensureing tool changing; The utility model increases by one section of cylinder 9 coaxial with the handle of a knife conical surface at the miner diameter end of handle of a knife 2, and by polygon for this cylinder 9 mill off, allows the face of cylinder 9 only have leptoprosopy to contact with the central shaft 1 of main axle unit, thus more reliable when ensureing that tool changing is blown.
