Magnechuck is one electromagnetic principle, and being energized by making Inside coil produces magnetic force, through magnetic conduction panel, contact is tightly held at the workpiece of panel surface, by coil blackout, magnetic force disappears and realizes demagnetization, takes off the principle of workpiece and a kind of machine tool accessories product of producing.The structure of current magnechuck inside is all iron cores of evenly having arranged therein, and the coil be coiled on iron core produces magnetic field after leading to direct current, and the magnetic direction that each iron core produces unanimously superposes to inhale afterwards eats magnetic substance workpiece; Otherwise then by after cut-out direct current, discharge workpiece.Magnechuck is in view of self applying working condition environmental quality, and during work, grinding machine can produce a large amount of heats due to polishing workpiece, and heat assembles the magnechuck that guiding directly contacts with workpiece in a large number in short-term; Simultaneously the electromagnet of suction cup interior also can produce a large amount of heats and finally also to lead the outer surface of magnechuck; Finally cause sucker to produce deformation, change workpiece grinding position, directly affect the machining accuracy of workpiece.In addition, the rising due to sucker temperature can reduce the suction of sucker to a certain extent, easily causes the phenomenon that processing work loosens, and changes Working position; The security incident that workpiece throws away also is caused time serious.
As a kind of water-cooled electromagnetic sucker of notification number CN202763667U, 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, the tank of spiral is had in described cooled region, described tank is provided with and is communicated with outside water inlet, delivery port, is provided with O RunddichtringO between the inside and outside anchor ring of described cooled region.The caloric value of electromagnet is absorbed by designing aqua storage tank in sucker, thus protection main shaft, and then guarantee grinding position.But this water storage tank structure is complicated, dismounting trouble, and cooling water is easily revealed.
Summary of the invention
Object of the present invention solves the problems of the technologies described above, and provides a kind of good cooling results, be not easy reveal with thermostatically controlled electromagnetic chuck device.
Technical solution of the present invention is: a kind of with thermostatically controlled electromagnetic chuck device, comprise magnechuck parts, erection copper pipe in described magnechuck parts, the two ends of described copper pipe are stretched out magnechuck parts and are connected feed tube and drain pipe respectively, and described feed tube and drain pipe are connected in refrigerator jointly; Described magnechuck parts comprise sucker, magnet and lower casing, and described copper pipe is wrapped in the surface of magnet; The side pipe that described copper pipe comprises parcel magnet four sides and the bottom tube covered on magnet bottom surface, described side pipe is by bending tube connecting bottom tube.
Cover each surface with magnet by copper pipe, increase the contact area of copper pipe and magnet, thus increase cooling effect.And constantly extract cooling water out in refrigerator, ensure that the cooling water of certain chilling temperature moves in copper pipe, and be exactly not fix a part of cooling water in action, cause after working long hours, cooling water is also heated, and loses the effect of cooling.
As preferably, one end of described side pipe connects feed tube, and the other end connects bending tube, and bending tube connecting bottom tube again, bottom tube is left one end and connects drain pipe.Whole side pipe, bending tube, bottom tube are communicated with becomes a pipe, both ensure that contact area, and in turn saves material.
As preferably, the bend pipe that described bottom tube comprises many row's straight tubes and is connected by adjacent straight tube head and the tail.Add the contact area between bottom tube and magnet, improve radiating effect.
As preferably, the upper surface of described magnet is connected with sucker one, and described sucking disc cover is combined on lower casing, and described magnet is contacted with lower casing inner surface by copper pipe.Copper pipe contacts with in lower casing, both cools magnet by cooling water, and carrys out heat conduction again by the contact of copper pipe and lower casing.
As preferably, described lower casing is offered for the through hole by feed tube or drain pipe.
As preferably, arrange at least 2 temperature sensors in described magnechuck parts, described temperature sensor is communicated with modular converter by electric wire, and described modular converter is connected with the controller for controlling refrigerator.
Beneficial effect of the present invention is:
Ensure that magnechuck is in the process of grinding machine processing work by the cooling water control of this device, all the time be in the temperature range set by processing technology, effectively control the range of temperature of magnechuck, reduce the deformation that magnechuck causes due to variations in temperature, improve machining accuracy.Meanwhile, also avoid the phenomenon of the force of suction cup decline that high temperature in sucker causes, improve machining accuracy, eliminate potential safety hazard.
