Abstract

The invention discloses a tool bit assembly of a novel computerized numerical control (CNC) glass cutting machine, and relates to a tool bit of a cutting machine. The assembly consists of a tool chuck assembly at the front end, a tool bit assembly on the middle part and a motor at the top, wherein the tool bit assembly comprises a toolbar, one end of the toolbar is connected with the tool chuck assembly, and the other end of the toolbar is provided with a driven sleeve; the driven sleeve is connected with one end of a driving sleeve to form a whole through bolts, the other end of the driving sleeve is connected with the power output shaft of the motor, the toolbar is driven by the motor to rotate, and meanwhile, the toolbar moves up and down under the action of air pressure; a return pressure spring is arranged in the cavity of the driven sleeve, the return pressure spring is sleeved outside the toolbar, one end of the return pressure spring is contacted with a concave table arranged on the cavity of the driven sleeve, and the other end of the return pressure spring is contacted with a supporting ring; the supporting ring is just arranged at the joint of the toolbar and the driving sleeve; and a Y-shaped sealing ring is sleeved on the exterior of the supporting ring. The tool bit assembly has the advantages that: the original retainer ring is changed into the supporting ring and the Y-shaped sealing ring, the supporting ring and the Y-shaped sealing ring form two independent air cavities in the driven sleeve, and the pressure area of the supporting ring is improved by 3.5 times, so the stability of setting and cutting pressure of the tool bit is greatly improved.

Description

A kind of novel CNC glass cutting machine tool bit assembly
Technical field
The present invention relates to the cutter head of cutting machine, a kind of specifically novel CNC glass cutting machine tool bit assembly.
Background technology
In the prior art, the roll setting and the cutting pressure of CNC glass cutting machine cutter head are controlled and are regulated by air pressure, air pressure in the driven cover of tool bit assembly with certain pressure action on the back-up ring that links together with knife bar (referring to Fig. 1), knife bar fallen or keep certain cutting pressure thereby form certain downward pressure.Top and bottom by back-up ring thereon exist by air pressure pressure, so the pressure area that acts on the back-up ring is exactly that back-up ring exposes the poor of area up and down, this area has only 2.3cm usually 2, the pressure that produces under the pressurized air that industry is used always is also just very little, as increasing pressure of compressed air, owing to the gap between knife bar and the driven cover, will inevitably cause the instability of cutter head roll setting and cutting pressure.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of novel CNC glass cutting machine tool bit assembly, is used to improve the stability of cutter head roll setting and cutting pressure.
Technical problem to be solved by this invention realizes by the following technical solutions,
A kind of novel CNC glass cutting machine tool bit assembly, cutter holder assembly by front end, the tool bit assembly at middle part and the motor at top constitute, described tool bit assembly comprises knife bar, outer setting orienting sleeve and cutter box at described knife bar, being used to limit knife bar is not offset when moving up and down, one end of described knife bar is connected with the cutter holder assembly, the other end is provided with from drive sleeve, a described end from drive sleeve and main transmission cover fuses by bolt, the other end of described main transmission cover and the power output shaft of motor are connected, rotate by the driven by motor knife bar, simultaneously, knife bar moves up and down under the effect of air pressure, it is characterized in that: from the inner chamber of drive sleeve recoil press spring is set described, described recoil press spring is enclosed within outside the knife bar, and an end and the concave station that is provided with from the drive sleeve inner chamber contact, the other end contacts with supporting cup, described supporting cup just in time is arranged at the junction of knife bar and main transmission cover, is with Y type wear ring in the outside of described supporting cup, is used to improve the pressure area of supporting cup.
Plug screw is set, the outer setting supporting base in the inner chamber of described main transmission cover.
A described end that is arranged on the outside of knife bar and main transmission cover from drive sleeve fuses by bolt, is provided with positioning key between drive sleeve and knife bar.
The front end of described cutter holder assembly is provided with the break bar folder, and break bar is fixed on the break bar folder.
The utility model is in when work, and electric motor driving main transmission cover drives knife bar and rotates, and simultaneously, knife bar moves up and down in orienting sleeve under the effect of air pressure, also drives cutter head and moves up and down and rotate, and finishes cutting action.
The beneficial effects of the utility model are to change original back-up ring into a supporting cup and Y V-shaped ring, supporting cup and Y type wear ring are forming 2 independently air cavitys from drive sleeve interior, because the pressure area of supporting cup is brought up to original 3.5 times, has improved the stability of cutter head roll setting and cutting pressure greatly.
Description of drawings
Fig. 1 is the synoptic diagram of prior art guide ring;
Fig. 2 is a structural representation of the present invention;
Fig. 3 is the synoptic diagram that the present invention improves back supporting cup and Y V-shaped ring.
Embodiment
