Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic chucks, in particular to an electromagnetic chuck for absorbing workpieces with high magnetic lines of force. Background Art

[0002] The electromagnetic chuck is a machine tool accessory product that uses the electromagnetic principle to generate magnetic force by energizing the internal coil, and then tightly sucks the workpiece in contact with the surface of the panel through the magnetic conductive panel. When the coil is powered off, the magnetic force disappears to achieve demagnetization and remove the workpiece.

[0003] Electromagnetic chucks are indispensable in the process of machine tool processing. When processing metal workpieces that are difficult to clamp, the electromagnetic chuck can be used to tightly and conveniently fix the workpiece on the surface of the chuck. However, during use, long-term power supply often causes the electromagnetic chuck to overheat, thereby reducing its magnetic properties, causing certain troubles to the user. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an electromagnetic chuck for adsorbing workpieces with high magnetic lines of force.

[0005] The utility model is implemented by the following technical scheme: an electromagnetic chuck for adsorbing workpieces with high magnetic lines of force, comprising a cooling mechanism, an electromagnetic mechanism and a fixing mechanism, wherein the cooling mechanism is located inside the fixing mechanism, and the electromagnetic mechanism is located on the upper surface of the fixing mechanism;

[0006] The cooling mechanism comprises a water pipe, the outer wall of the water pipe is threadedly connected with a water inlet, the outer wall of the water inlet is provided with a threaded opening, the outer wall of the water inlet is fixedly connected with a cooling pipe, and the outer wall of the cooling pipe is fixedly connected with a water outlet.

[0007] Through the above technical scheme, the water pipe is fixedly connected to the water inlet and the water outlet, and a threaded opening is opened outside the water inlet and the water outlet, and is tightly connected to the water pipe through the threaded opening, so as to prevent condensation from flowing out and causing environmental pollution due to gaps between the water pipe and the water inlet and the water outlet. The water inlet and the water outlet are fixedly connected to the cooling pipe, and the cooling water flowing in the cooling pipe takes away the heat generated during the electromagnet power-on process, so as to prevent the magnetism of the electromagnet from decreasing due to excessive heat, causing the workpiece to fall during the processing.

[0008] As a further improvement of the above solution, a heat-conducting copper plate is fixedly connected to the outer wall of the cooling tube.

[0009] Through the above technical solution, the cooling pipe is fixedly connected to the heat-conducting copper plate. By arranging the cooling pipe to closely adhere to the outer wall of the heat-conducting copper plate, the temperature on the heat-conducting copper plate is transferred and carried away by the cooling pipe. By arranging a plurality of copper pipes on the outer wall of the heat-conducting copper plate, the copper pipes are tightly adhered to the lower surfaces of the coil and the iron core, and the effect of rapid heat dissipation is achieved by increasing the heat-conducting area.

[0010] As a further improvement of the above solution, a fixing buckle is clamped on the outer wall of the cooling pipe, and a first fixing screw is threadedly connected to the inner wall of the fixing buckle.

[0011] Through the above technical solution, the cooling pipe is clamped with the fixing buckle, and the cooling pipe is fixed to the outer wall of the heat-conducting copper plate by the fixing buckle and the first fixing screw, which increases the stability of the overall mechanical equipment and prevents the cooling pipe from detaching from the heat-conducting copper plate due to vibrations generated during processing, thereby reducing the overall heat dissipation efficiency.

[0012] As a further improvement of the above solution, the electromagnetic mechanism includes a magnetic conduction plate, a positioning hole is provided on the outer wall of the magnetic conduction plate, a second fixing screw is threadedly connected to the inner wall of the positioning hole, and an electromagnetic housing is threadedly connected to the outer wall of the second fixing screw.

[0013] Through the above technical solution, a positioning hole is provided on the outer wall of the magnetic conduction plate. The second fixing screw is threadedly connected through the positioning hole, and the second fixing screw is threadedly connected to the electromagnetic housing. The magnetic conduction plate is fixedly connected to the electromagnetic housing by the second fixing screw, thereby increasing the stability of the overall structure.

[0014] As a further improvement of the above solution, a resin insulation layer is fixedly connected to the inner wall of the electromagnetic housing, a coil is fixedly connected to the outer wall of the resin insulation layer, an iron core is arranged inside the coil, and a power connection port is fixedly connected to the outer wall of the electromagnetic housing.

[0015] Through the above technical solution, the electromagnetic housing is fixedly connected to the resin insulation layer. By arranging the resin insulation layer on the outer wall of the coil, it is prevented that when the coil is energized, the entire equipment housing is electrified due to current leakage, which affects the safety of the operator. The power connection port is fixedly connected to the electromagnetic housing. When the power connection port is connected to the power supply, the coil is energized to generate an electromagnetic field, and the iron core inside the coil generates strong magnetism due to the magnetic field, so that the workpiece can be tightly adsorbed on the outer wall of the magnetic conduction plate to achieve the effect of fixing the workpiece.

[0016] As a further improvement of the above solution, the fixing mechanism includes a fixing base, a fixing ear is fixedly connected to the outer wall of the fixing base, a fixing nut is threadedly connected to the outer wall of the fixing ear, and a fixing screw is threadedly connected to the inner wall of the fixing nut.

[0017] Through the above technical solution, the fixed base is fixedly connected to the fixed ear, the fixed ear is threadedly connected to the fixed nut, and the fixed nut is threadedly connected to the fixed screw. By fixedly connecting the fixed base to the fixed ear, the stability of the overall structure is increased.

[0018] As a further improvement of the above solution, the outer wall of the fixed screw is threadedly connected to the machine tool bracket.

[0019] Through the above technical solution, the fixed screw is fixedly connected to the machine tool bracket, and the fixed ear is fixedly connected to the fixed base. The fixed ear is fixed on the upper surface of the machine tool bracket through the fixed nut and the fixed screw, thereby increasing the stability of the overall mechanical structure.

The cooling pipe is fixedly connected to the heat conduction copper plate. By arranging the cooling pipe closely attached to the outer wall of the heat conduction copper plate, the temperature on the heat conduction copper plate can be efficiently transferred, and the heat is taken away by the cooling pipe. A plurality of copper pipes are arranged on the outer wall of the heat conduction copper plate to increase the contact area with the coil and the iron core, improving the heat dissipation efficiency. The cooling pipe is clamped to a fixed buckle, and the cooling pipe is fixed to the outer wall of the heat conduction copper plate through the fixed buckle and the first fixing screw, enhancing the stability of the entire mechanical equipment and preventing the cooling pipe from detaching from the heat conduction copper plate due to vibration during the processing, thereby reducing the overall heat dissipation efficiency.
