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 spindle processing technology, relate in particular to a kind of horizontal high-speed main shaft central hole grinding machine.
Background technology
Electricity main shaft is the electromechanical integrated product that a kind of technology content is very high, through development and improvement constantly, its application spreads all over machine industry, bearing industry, electronics processing industry, Mould Machining industry, instrument processing industry and all need the enterprise of High Rotation Speed and High-speed machining.In machining spindle process, can spindle hole machining accuracy guarantee, will directly have influence on the precision quality of whole electric main shaft.
Traditional processing method is to adopt common grinding method to improve spindle hole precision, is with standard universal circular grinding machine, to adopt Double Tops pin to add abrasive pastes 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 within tens minutes, just can reach the effect that improves surface smoothness.
B. because grinding, spindle hole carries out after main shaft heat-treatment quenching, 60 ° of centre bore surfaces of many main shafts have the oxidation lump producing in heat-treatment quenching process, and in transportation, carrying, heat treatment operation process, the hard spot that collides with is caused in 60 ° of centre bore surfaces, when abrasive pastes grind, lump does not come out at all.
Summary of the invention
Object of the present invention will provide a kind of horizontal high-speed main shaft central hole grinding machine exactly, and it can overcome the existing problem of processing method of traditional spindle hole.The object of the present invention is achieved like this, a kind of horizontal high-speed main shaft central hole grinding machine, comprise that clamping transmission device, centre frame, 60 ° of dressers form, it is characterized in that: on the head of a bed of universal circular grinding machine, be provided with clamping transmission device, the middle part on universal circular grinding machine is provided with centre frame, 60 ° of dressers from left to right; Right front on universal circular grinding machine is provided with 48000 revs/min 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 spindle hole machining accuracy than tradition processing adopt abrasive pastes grinding center hole precision high what, working (machining) efficiency improves nearly ten times than traditional diamond-making technique.
