Abstract
The utility model provides a water-cooling electromagnetic chuck. The water-cooling electromagnetic chuck takes away partial heat through a cooling liquid, wherein the heat is produced by an electromagnet, enables a small amount of heat to be conducted to a main shaft and then the main shaft is not caused to deform or extend, and therefore a grinding position and a high-precision grinding of a grinder are guaranteed. The water-cooling electromagnetic chuck comprises the electromagnet, the chuck, the main shaft and a shell, wherein the electromagnet is arranged in the shell in a sleeved mode, a central hole of the shell is provided with the main shaft in a sleeved mode, the tail end of the main shaft is provided with an end cap and the front end of the main shaft is connected with the chuck. The water-cooling electromagnetic chuck is characterized in that a cooling plate is arranged between the back end face of the shell and the front end face of the end cap, the cooling plate is arranged on the main shaft in a sleeved mode, an end face attached to the back end face of the shell of the cooling plate is provided with a cooling area, a spiral trough is formed in the cooling area, a water inlet which is communicated with external and a water outlet which is communicated with external are formed in the trough and an O-shaped seal ring is arranged between an inner torus of the cooling area and an outer torus of the cooling area.
Description
Technical field
The utility model relates to the technical field of structures of magnechuck, is specially a kind of water-cooled electromagnetic sucker.
Background technology
Magnechuck in the existing electric magnetic no-core clamp all adopts electromagnet, magnechuck does not possess active cooling function, can only natural heat dissipation, because the function of current, electromagnet can generate heat, and heat can be transmitted to work spindle and cause the main shaft thermal deformation, elongation, affect grinding position, finally cause the grinding machine precision.
Summary of the invention
For the problems referred to above, the utility model provides a kind of water-cooled electromagnetic sucker, it is taken away the part heat that electromagnet distributes by cooling fluid, so that after a small amount of heat of electromagnet heating conducts to main shaft, can not cause spindle deformation, elongation, and then guarantee grinding position, guarantee the high-precision grinding of grinding machine.
A kind of water-cooled electromagnetic sucker, its technical scheme is such: it comprises electromagnet, sucker, main shaft, shell, be set with described electromagnet in the described shell, be set with described main shaft in the centre bore of described shell, the afterbody of described main shaft is with end cap, the front end of described main shaft is connected with described sucker, it is characterized in that: between the rear end face of described shell and the front end face of described end cap coldplate is housed, described coldplate is set in described main shaft, the fit end face of rear end face of described shell of described coldplate is provided with cooled region, have the tank of spiral in the described cooled region, described tank is provided with and is communicated with outside water inlet, delivery port is in the described cooled region, be provided with the O RunddichtringO between outer ring surface.
It is further characterized in that: the air portion that exposes to of described shell is divided and is had the cooling heat dissipation groove.
After adopting said structure of the present utility model, the end face of the rear end face of described shell is provided with cooled region because coldplate is fitted, have the tank of spiral in the described cooled region, described tank is provided with and is communicated with outside water inlet, delivery port, in the described cooled region, be provided with the O RunddichtringO between outer ring surface, cooling water enters in the tank of spiral by water inlet, thereby take away the heat that electromagnet one side passes to shell, namely by cooling fluid most of heat that electromagnet distributes is taken away, so that after a small amount of heat of electromagnet heating conducts to main shaft, can not cause spindle deformation, elongation, and then guarantee grinding position, guarantee the high-precision grinding of grinding machine.
Description of drawings
Fig. 1 is front view structural representation of the present utility model;
Fig. 2 is right view structural representation of the present utility model.
The specific embodiment
See Fig. 1, Fig. 2, it comprises electromagnet 1, sucker 2, main shaft 3, shell 4, be set with described electromagnet 1 in the described shell 4, be set with described main shaft 3 in the centre bore of described shell 4, the afterbody of described main shaft 3 is with end cap 5, the front end of described main shaft 3 is connected with described sucker 2, it is characterized in that: between the front end face of the rear end face of described shell 4 and described end cap 5 coldplate 6 is housed, described coldplate 6 is set in described main shaft 3, the end face of the rear end face of the described shell 4 of described coldplate 6 applyings is provided with cooled region, have the tank 7 of spiral in the described cooled region, described tank 7 is provided with and is communicated with outside water inlet 8, delivery port 9 is in the described cooled region, be provided with O RunddichtringO 10 between outer ring surface.
The air portion that exposes to of shell 4 is divided and is had cooling heat dissipation groove 11.Cooling heat dissipation groove 11 has strengthened the contact area of shell and air, dispels the heat faster.
