Description

Raised type gear hobbing knife rest
Technical field
The utility model relates to a kind of knife rest, particularly relates to a kind of shaft-like workpiece at big ring flange axle type gear at the gear-hobbing machine knife rest.
Background technology
Gear-hobbing machine is most widely used a kind of lathe in the gear cutting machine, machinable straight-tooth, helical gears on gear-hobbing machine, but also machining worm wheel, sprocket wheel etc.When gear-hobbing machine cuts being installed in workpiece on the workbench, bear the cutting force of interrupted impact and guarantee machining accuracy, this just requires, and tool holder stiffness is good, precision is high, good anti-vibration.Traditional plain edition knife rest, in order to guarantee its rigidity and vibration resistance, usually hobboing cutter main shaft axial feed direction be equipped with hobboing cutter main shaft support piece up and down, with hobboing cutter main-shaft axis semi-surrounding, to increase rigidity.The traditional knife rest of this structure has guaranteed rigidity and vibration resistance, but because hobboing cutter main shaft support piece is arranged with the main-shaft axis semi-surrounding, below the hobboing cutter main shaft frock clamp can not be arranged, or the big ring flange of processed object.Like this, traditional knife rest limits to some extent to frock clamp, must use special frock clamp, and traditional knife rest can not carry out gear hobbing processing from the nearer shaft-like workpiece of tooth portion to big ring flange.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of raised type gear hobbing knife rest that can carry out gear hobbing processing to big ring flange from the nearer axle class of tooth portion.
The technical solution of the utility model is as follows: a kind of raised type gear hobbing knife rest, comprise tool holder casing (1), be equipped with transmission chain rivet (2) on the described tool holder casing (1), this tool holder casing (1) is provided with hobboing cutter main shaft support piece (3), and this hobboing cutter main shaft support piece (3) is axial arranged along transmission chain rivet (2), have on the described tool holder casing (1) and only be provided with a hobboing cutter main shaft support piece (3), offer hobboing cutter opening (3a) on this hobboing cutter main shaft support piece (3), and this hobboing cutter opening (3a) is outside tool holder casing (1), and the below of described hobboing cutter main shaft support piece (3) is provided with hobboing cutter main shaft bracket.
Employing in use, is sleeved on hobboing cutter on the hobboing cutter main shaft with upper tool post, then the hobboing cutter main shaft is worn in the hobboing cutter main shaft bracket, make hobboing cutter be positioned at opening part, add man-hour, give the hobboing cutter main shaft by the transmission chain rivet with transmission of power, the hobboing cutter main shaft drives hobboing cutter rotation processing again.This knife rest make on the hobboing cutter main shaft the space of the hobboing cutter of adorning below vacate fully, adding the big ring flange that can not interfere with frock clamp or workpiece to be machined man-hour, just can carry out gear hobbing from the nearer shaft-like workpiece of tooth portion and process big ring flange.
In order to improve cutting force and tool holder stiffness, the center line place horizontal plane of described hobboing cutter main shaft bracket (4) is positioned at the below of transmission chain rivet (2) axial line place horizontal plane, is adding man-hour, not only has horizontal cutting power, also has vertical cutting force.
For better fixedly hobboing cutter main shaft bracket, the inner surface of described hobboing cutter main shaft support piece (3) is a semi-cylindrical, the outer peripheral face first half of described hobboing cutter main shaft bracket (4) is a semi-cylindrical, and the outer peripheral face first half of this hobboing cutter main shaft bracket (4) matches with the inner surface of hobboing cutter main shaft support piece (3); On the side face of described hobboing cutter main shaft bracket (4), offer twice holddown groove (4a), this holddown groove of twice (4a) is all offered along hobboing cutter main shaft bracket (4) length direction, and this holddown groove of twice (4a) is symmetricly set on the both sides of hobboing cutter main shaft bracket (4) outer peripheral face, in described holddown groove (4a), be provided with fixed block (5), this fixed block (5) stretches out outside the holddown groove (4a), and this fixed block (5) is fixedly connected on the below of hobboing cutter main shaft support piece (3).
For weight reduction, one of them side of the upper side of described hobboing cutter main shaft support piece (3) and tool holder casing (1) at grade, and the upper surface of this hobboing cutter main shaft support piece (3) is downward-sloping in horizontal plane.
Beneficial effect: the utility model has been cancelled the back-up block of hobboing cutter main shaft bracket below, position with the hobboing cutter spindle centerline moves down simultaneously, the space of hobboing cutter below is vacated fully, adding the big ring flange that can not interfere with frock clamp or workpiece to be machined man-hour, also have simple in structure, with low cost, characteristics such as safety simple to operate.
