Abstract

The utility model relates to a machine tool automatic tool change device, which belongs to the numerically-controlled machine tool technology field. The device comprises a main axle controlled by a microcomputer controller, a clamping head connected at the lower part of the main axle and a tool magazine formed by connecting a plurality of tool holders into a row. The utility model is characterized in that the middle of the bottom surface of the outer sleeve (4) of each tool holder in the tool magazine is hollowed, a clamping tool holder (3) is nested in the outer sleeve (4), a tool snap ring (2) is embedded at the upper part of the clamping tool holder (3), a tool (1) is inserted in the tool snap ring (2), a pneumatic cylinder type thimble is arranged under the tool magazine, and is connected with one end of a solenoid valve (11), and the other end of the solenoid valve (11) is connected with a microcomputer controller (9). Compared with the prior art, the main axle is not required to move vertically, a tool grasping arm is not required to assist in grasping the tool, the tool magazine is not required to be buffered, thereby the tool changing speed is quickened, and the tool changing efficiency is enhanced.

Description

The lathe automatic tool changer

[technical field]

The utility model relates to the numerical control machine tool technique field, specifically a kind of lathe automatic tool changer.

[background technology]

Existing drilling machine and forming machine, tool changing need main shaft not only will move horizontally but also will move up and down, and need during tool changing attachedly grab or cushion tool magazine and assist tool changing, and tool-changing speed is slower, also be prone to cutter grab not firm, caducous situation.

[summary of the invention]

The purpose of this utility model is to overcome the deficiencies in the prior art, sets up thimble below tool magazine, makes thimble cooperate operation with main shaft, improves tool-changing speed.

For achieving the above object, design a kind of lathe automatic tool changer, comprise main shaft by microcomputer controller control, the chuck that the main shaft below connects, connect tool magazine in a row by a plurality of tool rests, it is characterized in that: hollow out in the middle of the bottom face of the outer sleeve of each tool rest (4) in the tool magazine, be inserted in folder tool rest (3) in the outer sleeve (4), folder tool rest (3) top embeds cutter clasp (2), cutter (1) inserts in the cutter clasp (2), the tool magazine below is provided with a pneumatic cylinder formula thimble, pneumatic cylinder formula thimble connects magnetic valve (11) one ends, and magnetic valve (11) other end connects microcomputer controller (9).Described pneumatic cylinder formula thimble is to have an end of piston to insert in the pneumatic cylinder (6) apical axis (5), outer apical axis (5) other end of pneumatic cylinder (6) is provided with the magnetic sheet (12) vertical with apical axis (5), the upper and lower of pneumatic cylinder (6) is established upper and lower pore respectively, and the upper and lower pore of pneumatic cylinder (6) adopts gas circuit (10) to connect magnetic valve (11).

The utility model is compared with prior art, and main shaft need not move up and down, and does not need to grab that tool arm is auxiliary grabs cutter, need not cushion tool magazine, has accelerated tool-changing speed, has improved the efficient of tool changing.

[description of drawings]

Fig. 1 is a structural representation of the present utility model.

Appointment Fig. 1 is a Figure of abstract.

Referring to Fig. 1,1 is cutter; 2 is the cutter clasp; 3 are the folder tool rest; 4 is outer sleeve; 5 is apical axis; 6 is pneumatic cylinder; 7 is chuck; 8 is main shaft; 9 is microcomputer controller; 10 is gas circuit; 11 is magnetic valve; 12 is magnetic sheet.

[specific embodiment]

Below in conjunction with accompanying drawing the utility model is further described.

Embodiment:

Under 9 controls of microcomputer controller, main shaft 8 rapid horizontal are wanted the tool rest position of tool changing in the tool magazine, the thimble of being made up of apical axis 5 and pneumatic cylinder 6 also is moved horizontally to the tool rest position of tool changing as main shaft 8 simultaneously, and the chuck under the main shaft 87 opened, microcomputer controller 9 is also controlled magnetic valve 11 and is given magnetic valve 11 air feed with the gases at high pressure of outside by the tracheae of magnetic valve 11 bottoms, the gas circuit 10 of passing through to connect is then given pneumatic cylinder 6 bottom inflows below the tool rest, gas is apical axis 5 jack-up, the magnetic sheet 12 at apical axis 5 tops will press from both sides tool rest 3 jack-up by the hollow out place in the middle of outer sleeve 4 bottoms, folder tool rest 3 externally slides upwards in the sleeve 4, and cutter 1 driven upwards in the lump together with cutter clasp 2, cutter 1 extends upwardly in the chuck 7 of main shaft 8 belows, chuck 7 closures then, clamp-on tool 1, microcomputer controller 9 is controlled magnetic valves 11 simultaneously, make pneumatic cylinder 6 by the top air inlet, and base bleed, gas promotes piston and down moves, piston drives apical axis 5 and magnetic sheet 12 down moves, magnetic sheet 12 can hold folder tool rest 3 and drive it and down move and reset, and just finishes thus and once presss from both sides the cutter process; Put the cutter order then in contrast, when main shaft 8 wants to change another cutter, main shaft 8 is above level under the control of microcomputer controller 9 moves on to original cutter 1, apical axis 5 will press from both sides tool rest 3 jack-up again under the promotion of pneumatic cylinder 6 simultaneously, subsidiary cutter clasp 2 is playbacked in the folder tool rest 3, chuck 7 unclamps, main shaft 8 moves to the top of another cutter that will press from both sides, apical axis 5 and pneumatic cylinder 6 also move to the below of this cutter place tool rest simultaneously, repeat the process of above-mentioned folder cutter.
