Abstract

The invention discloses a V-shaped groove frame. A half-round counter bore which is used for placing a knife handle is formed in the V-shaped groove frame, a key groove is formed below the half-round counter bore, and through-holes and threaded holes are formed in left and right sides of the V-shaped groove frame. A front end face a of the knife handle is used for supporting; an external circle b of the knife handle is used for positioning in a matching mode; a socket head cap screw with a 60-degree head is used for positioning the axial direction of the knife handle to prevent the knife handle from falling when the knife handle is placed; a flat key is matched with the knife handle key groove to position the circumferential direction of the knife handle so as to guarantee the correctness of positions of the knife handle key groove and a main shaft positioning key during knife holding; and steel balls, springs and screws are used for tightly pressing the position of a knife handle positioning V-shaped groove c so as to guarantee that the knife handle is not separated from a knife rest when placed on the V-shaped groove frame and moved with a workbench. Compared with existing vertical machining center in-magazine knife holding technologies, the V-shaped groove frame has the advantages of being capable of automatically changing heavy, long and large knives which can not be placed into a magazine, broadening the application range of a vertical machining center and improving the universality of the vertical machining center.

Description

A kind of V-type truss

Technical field

The present invention relates to the storehouse external memory knife rest of a kind of vertical machining centre and vertical numerical control milling machine, specifically realize the knife rest of the JT50 handle of a knife storehouse external memory cutter that vertical machining centre and vertical numerical control milling machine are used, realize on the workbench placing heavily by it is installed in, long, big cutter.

Background technology

Machinery generally uses vertical processing in the industry, and its tool magazine of wearing has corresponding restriction to the weight of cutter, length, diameter etc.As: φ 315 facing cutters that finish-milling engine cylinder block end face is used can not be put tool magazine into, can only adopt the form of storehouse external memory cutter to realize the automatic replacing of this facing cutter.At present, the cutter that can not put tool magazine usually into adopts following two kinds of methods usually: (1) adopts artificial tool changing; (2) fixedly processing content, not more tool changing.The first method weak point is that labour intensity is big, and production efficiency is low; The second method weak point is that the versatility of machining center is dwindled, and technological flexibility reduces.

Summary of the invention

At the deficiencies in the prior art, the invention provides a kind of practicality for solution vertical machining centre storehouse external memory cutter and deposit knife rest, the difficult problem that this V-type truss can finely solve that vertical machining centre is overweight, overlength, super large cutter can not automatic tool changers, improve efficiency of equipment greatly, also greatly reduce working strength of workers.V-type truss of the present invention is applicable to the storehouse external memory cutter of all vertical machining centres, also is applicable to vertical numerical control milling machine storehouse external memory cutter.

Technical solution of the present invention is such, a kind of V-type truss, mainly include and deposit knife rest, steel ball, holddown spring, adjust screw, dog screw, deposit the cutter gripper shoe, location flat key and location flat key lock-screw, there are two through holes the end above it is characterized in that storehouse external memory cutter gripper shoe, an installation dog screw, another installs steel ball, holddown spring, adjust screw, the location flat key lock-screw of the semicircle counterbore below of storehouse external memory cutter gripper shoe is fixed in storehouse external memory cutter gripper shoe to the location flat key, deposit knife rest and have the semicircle counterbore of placing handle of a knife, semicircle counterbore below has keyway, deposits the knife rest left and right sides and has through hole and screwed hole.

The contact-making surface of described semicircle counterbore and handle of a knife front end face is supporting surface.

Described semicircle counterbore cooperates the location with the handle of a knife cylindrical, handle of a knife and deposit that monolateral gap is 0.15-0.5mm between the knife rest.

Described handle of a knife head has screw hole, and inserting head is that the soket head cap screw adjustment handle of a knife of 60 degree and the axial spacing of semicircle counterbore are 0.1-0.5mm.

Insert the location flat key in the described keyway, the circular gap of adjusting location flat key and handle of a knife is 0.1-0.5mm.

Insert steel ball, holddown spring, adjustment screw in the described through hole from inside to outside, compress handle of a knife location v type groove, steel ball compresses the size of handle of a knife power and regulates by adjusting screw, inserts dog screw in the described screwed hole.

Advantage of the present invention is: adopt handle of a knife front end face a to support; Handle of a knife cylindrical b cooperates the location (see figure 2); The position location accurately and reliably.Adopting head is that the soket head cap screw form position tool shanks at 60 ° of angles is axial, prevent from putting handle of a knife to the external memory knife rest of storehouse the time because the handle of a knife conical surface and machine tool chief axis cone match cause handle of a knife and main shaft finely not to break away from well, and cause the handle of a knife problem.Adopt flat key and the handle of a knife keyway position tool shanks that matches circumferential, handle of a knife keyway and main shaft positioning key correct position when guaranteeing to grab cutter.Adopt the form of steel ball+spring+adjustments screw to compress handle of a knife, guarantee that handle of a knife is placed on the external memory knife rest of storehouse when moving with workbench and can not break away from knife rest, and it compresses dynamics and can adjust by the adjustment screw.The mounting screw via hole adopts the adjustable form of circular arc, the tram of storehouse external memory knife rest when guaranteeing to install.
