Abstract
The invention discloses a horizontal high-speed spindle centre hole grinding machine. The grinding machine consists of a clamping transmission device, a centre frame and a 60-degree grinding wheel dresser, wherein the clamping transmission device is arranged on the machine head of a universal cylindrical grinding machine; the centre frame and the 60-degree grinding wheel dresser are arranged on the middle part of the universal cylindrical grinding machine from left to right; a high-speed electric spindle grinding head of 48,000 revolutions per minute is arranged on the right front of the universal cylindrical grinding machine; and a frequency converter is arranged at the right top end of the universal cylindrical grinding machine. A spindle centre hole is ground at high speed by using the horizontal high-speed spindle centre hole grinding machine, so that the machining precision of the spindle centre hole is a few levels higher than the precision of the centre hole which is ground by adopting grinding paste in conventional machining; and the machining efficiency is improved by nearly ten times compared with that in a conventional machining method.
Description
Technical field:
The present invention relates to a kind of electric main shaft process technology, relate in particular to a kind of horizontal high-speed spindle hole milling drum.
Background technology:
The electricity main shaft is the very high electromechanical integrated product of a kind of technology content; Through development and perfect constantly, its application spreads all over the enterprise of machine industry, bearing industry, electronics processing industry, Mould Machining industry, instrument processing industry and rotation of all needs high speed and High-speed machining.In the machining spindle process, can the spindle hole machining accuracy guarantee, with the precision quality that directly has influence on whole electric main shaft.
Traditional processing method is to adopt the common grinding method to improve the spindle hole precision, is to adopt the Double Tops pin to add abrasive pastes with the standard universal circular grinding machine spindle hole to be ground, can bring the problem of the following aspects;
A. abrasive pastes grinding spindle centre bore required time is long, grinds need and just can reach the effect that improves surface smoothness in tens minutes.
B. owing to grinding, spindle hole carries out later at the main shaft heat-treatment quenching; Many 60 ° of centre bore surfaces of main shaft have the oxidation lump that is produced in the heat-treatment quenching process; Reach in transportation, carrying, the heat treatment operation process hard spot that collides with is caused on 60 ° of centre bore surfaces, lump did not come out at all when abrasive pastes ground.
Summary of the invention: the object of the invention will provide a kind of horizontal high-speed spindle hole milling drum exactly, and it can overcome the existing problem of processing method of traditional spindle hole.The objective of the invention is to realize like this; A kind of horizontal high-speed spindle hole milling drum; Comprise that chucking transmission device, centre frame, 60 ° of dressers form; It is characterized in that: the head of a bed of universal circular grinding machine is provided with the chucking transmission device, and the middle part on the universal circular grinding machine is provided with centre frame, 60 ° of dressers from left to right; Right front on the universal circular grinding machine is provided with 48000 rev/mins of high-speed electric main shaft bistriques; The right top of universal circular grinding machine is provided with frequency converter.
The present invention carries out Speed Grinding to spindle hole, make the spindle hole machining accuracy than tradition processing adopt abrasive pastes grind the centre bore precision high what, working (machining) efficiency improves nearly ten times than traditional diamond-making technique.
Description of drawings:
Fig. 1 is a general assembly schematic perspective view of the present invention;
1. universal circular grinding machine; 2. chucking transmission device; 3. centre frame; 4.60 ° dresser; 5.48000 rev/min high-speed electric main shaft bistrique; 6. frequency converter;
The specific embodiment: the present invention is further described below in conjunction with accompanying drawing:
A kind of horizontal high-speed spindle hole milling drum; Comprise chucking transmission device 2,4 compositions of 3,60 ° of dressers of centre frame; It is characterized in that: the head of a bed of universal circular grinding machine 1 is provided with chucking transmission device 2, and the middle part on the universal circular grinding machine 1 is provided with 3,60 ° of dressers 4 of centre frame from left to right; Right front on the universal circular grinding machine 1 is provided with 48000 rev/mins of high-speed electric main shaft bistriques 5; The right top of universal circular grinding machine is provided with frequency converter 6.During practical implementation; Adopt the accurate M120 universal circular grinding machine of station symbol machine-tool, the grinding work piece spindle hole passes the chucking transmission device with work spindle one end earlier; The work spindle centre bore is enclosed within on the thimble of M120 universal circular grinding machine head of a bed center; The other end inserts in the centre frame, regulates the suitable distance of chucking transmission device length, and locking device; Regulating the position of the other end in centre frame, promptly is the elastic device of regulating on the centre frame, and locking device; Whether rotate M120 universal circular grinding machine head of a bed cephalic inspection main shaft with hand rotates flexible.The motor of opening on the M120 universal circular grinding machine rotates; Whether normal, the phenomenon of play forward must not be arranged if observing the work spindle running, and with the circular runout of micron order beat appearance measuring workpieces spindle nose whether in prescribed limit; Otherwise the position of adjustment work spindle in chucking transmission device, centre frame; Till reaching in the prescribed limit, and each device of locking, close the motor on the M120 universal circular grinding machine.Open frequency converter and 48000 rev/mins of operating parameters that the high-speed electric main shaft bistrique is complementary, after starting 48000 rev/mins of high-speed electric main shaft bistriques and working well, 60 ° of emery wheels of high-speed electric main shaft bistrique are revised with 60 ° of dressers; Reach till the requirement, and, remove 60 ° of dressers with after 60 ° of gauges detections; Open motor rotating band on the M120 universal circular grinding machine part main shaft of starting building; Be available 48000 rev/mins of high-speed electric main shaft bistriques to the processing of work spindle center hole grinding, meet processing request after, the work spindle tune; Processing other end work spindle centre bore, procedure of processing is with above identical.
