Description

Technical Field

[0001] This utility model relates to the field of electric spindle technology, specifically to a dual-effect cooling electric spindle. Background Technology

[0002] An electric spindle is a type of electrically driven spindle widely used in machine tools and machining equipment. Its main function is to directly drive the spindle to rotate via an electric motor, providing power for material processing. To ensure the normal operation of machine tools and machining equipment, a double-cooled electric spindle is required.

[0003] However, existing dual-effect cooling electric spindles have weak lubrication functions. When the rotating shaft works for a long time, it is not easy to lubricate the surface of the rotating shaft, which may lead to excessive rotational friction during long-term operation and affect the service life of the device. In addition, existing dual-effect cooling electric spindles have weak adjustment functions. During use, it is not convenient to quickly install, disassemble, and perform multi-angle adjustments according to the needs of the application scenario, which reduces the flexibility of the device. Utility Model Content

The rotating assembly includes a servo motor, the inner surface of which is fixedly connected to the inside of the groove. A fixed frame is fixedly connected to the surface of the rotating assembly. An electric spindle body is fixedly connected inside the fixed frame. A rotating shaft is disposed in the center of the surface of the electric spindle body. A lubrication assembly is fixedly connected to the surface of the electric spindle body, including a lubrication box fixedly connected to the surface of the electric spindle body. An extension plate is fixedly connected to the top of the electric spindle body, and a nozzle is fixedly connected to the top of the extension plate.

[0007] Preferably, both ends of the fixing plate are fixedly connected to external plates, and the interior of both sets of external plates is threaded with external screws.

[0008] Preferably, a number of ventilation openings are provided in the middle of the top surface of the electric spindle body, and a flow opening is provided on the back of the electric spindle body, with the inner top of the flow opening communicating with the inner bottom of the number of ventilation openings.

[0011] Preferably, the lubrication assembly further includes an oil inlet, the bottom of which is fixedly connected to the top of the lubrication tank, and a closing cap is snapped onto the top of the oil inlet.

[0012] Preferably, an adsorption layer is fixedly connected inside the lubrication box, and the surface of the adsorption layer is rotatably connected to the surface of the rotating shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This dual-effect cooling electric spindle, through the arrangement of lubrication components, nozzles, vents, and flow ports, allows the operator to remove the closed cover and pour lubricating oil into the lubrication tank through the oil inlet when the spindle is in operation for an extended period. The lubricating oil enters the lubrication tank and comes into contact with the adsorption layer, which absorbs the lubricating oil. When the electric spindle body is working, the adsorption layer and the rotating shaft repeatedly come into contact, making the rotating shaft rotate more smoothly. The nozzle can be connected to external equipment to spray water onto the surface of the electric spindle body and the rotating shaft for cooling. The vents and flow ports can accelerate air circulation, carrying away the heat generated by the electric spindle body during operation, thereby achieving dual-effect cooling and improving the practicality of the device.

[0015] 2. This dual-effect cooling electric spindle, through the setting of the rotating component, allows the operator to align and insert the B-block at the bottom of the electric spindle body with the A-block according to the needs of the usage scenario, then connect the external power supply, start the servo motor, and the servo motor drives the transmission rod and the A-block to rotate. The rotation of the A-block causes the B-block, the fixed frame, and the electric spindle body to rotate accordingly, and the angle can be adjusted. The engagement of the B-block and the A-block allows for quick disassembly and installation of the fixed frame and the fixed plate, thereby improving the flexibility of the device.
