Abstract
The utility model provides water-cooled cutter hobboing cutter group, comprise some by the connected dry milling cutter (1) of rotating shaft (2), it is characterized in that: in the middle of described rotating shaft (2), have tank (3), the tank (3) of some hobboing cutters (1) is located to connect by annular conduit, in described annular conduit, is provided with circulating pump.Described annular conduit is externally connected to air hot pipe or part immerses condensation pond.Utilize recirculated water some hobboing cutters to be carried out cooling simultaneously simultaneously, when recirculated water flows in annular conduit, take away the heat on hobboing cutter, be delivered in air, directly better by the mode cooling effect of air cooling than tradition, the working life that has extended hobboing cutter.
Description
Technical field
The utility model relates to cutting tool field, specifically a kind of water-cooled cutter hobboing cutter group.
Background technology
Cutter tooth is made Gear Processing cutter tool ﹐ that helix arranges for by generating processing circle post tooth wheel ﹑ worm gear and other cylindrical toothed workpiece (seeing that tooth wheel adds work ﹑ gear) along cylinder or circular cone.According to different ﹐ hobboing cutter of purposes, be divided into Chi wheel Gun Dao ﹑ Wo wheel Gun Dao ﹑ non-involute generate hobboing cutter and single position hob etc.。Add man-hour, hobboing cutter is equivalent to a helical gear that helical angle is very large, its number of teeth is a number of hobboing cutter, workpiece is equivalent to another helical gear, according to a pair of helical tooth crop rotation space, mesh each other, with the speed ratio rotation of fixing, by the cutter tooth profile of tooth envelope of each adjacent position of cutting successively, become tooth-formation of gear.During hobboing cutter cutting, because violent friction can produce high temperature, be to reduce the hobboing cutter major reason in service life, in prior art, conventionally by the mode of external ventilation, reduce the temperature on hobboing cutter surface.This method cooling-down effect is limited, and wind can dispel and add the flying chip producing man-hour, affect workman and works.
Utility model content
The utility model, in order to solve the overheated problem that causes life-span reduction of existing hobboing cutter, provides a kind of water-cooled cutter hobboing cutter group, reduces the temperature of hobboing cutter by recirculated water, can effectively extend the service life of hobboing cutter.
The utility model comprises some by the connected dry milling cutter of rotating shaft, in the middle of rotating shaft, has tank, and connecting by annular conduit in the tank place of some hobboing cutters, in described annular conduit, is provided with circulating pump.Utilize recirculated water some hobboing cutters to be carried out cooling simultaneously simultaneously, when recirculated water flows in annular conduit, take away the heat on hobboing cutter, be delivered in air, directly better by the mode cooling effect of air cooling than tradition, the working life that has extended hobboing cutter.
Further improve, described annular conduit is externally connected to air hot pipe.By having improved the cooling velocity of cooling circulating water at the outside heat pipe that increases of water pipe, thereby further improved the radiating effect of hobboing cutter.
Further improve, described annular conduit partly immerses condensation pond.By condensation pond, make cool cycles water for cooling, radiating effect is better than air hot pipe, and shortcoming is that cost is higher, can use according to needs of production.
Accompanying drawing explanation
Fig. 1 is the utility model module diagram.
Fig. 2 is hob-cutter structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model comprises some by the connected dry milling cutter 1 of rotating shaft 2, has tank 3 in the middle of rotating shaft 2.Hob-cutter structure as shown in Figure 2.Water circulation structure as shown in Figure 1, connect by annular conduit, in described annular conduit, is provided with circulating pump by tank 3 places of some hobboing cutters 1.
When the outside connection of annular conduit air hot pipe, by having improved the cooling velocity of cooling circulating water at the outside heat pipe that increases of water pipe, thereby further improved the radiating effect of hobboing cutter.
When annular conduit partly immerses condensation pond, by condensation pond, make cool cycles water for cooling, radiating effect is better than air hot pipe, and shortcoming is that cost is higher, can use according to needs of production.。
The concrete application approach of the utility model is a lot; the above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
Claims (3)
1. a water-cooled cutter hobboing cutter group, comprise some by the connected dry milling cutter (1) of rotating shaft (2), it is characterized in that: in the middle of described rotating shaft (2), have tank (3), the tank (3) of some hobboing cutters (1) is located to connect by annular conduit, in described annular conduit, is provided with circulating pump.
2. water-cooled cutter hobboing cutter group according to claim 1, is characterized in that: described annular conduit is externally connected to air hot pipe.
3. water-cooled cutter hobboing cutter group according to claim 1, is characterized in that: described annular conduit partly immerses condensation pond.
