Description

Technical Field

[0001] The utility model relates to the technical field of electric spindles, in particular to an electric spindle cooling mechanism which is easy to disassemble and assemble. Background Art

[0002] The electric spindle is a new technology that integrates the machine tool spindle and the spindle motor in the field of CNC machine tools. Together with linear motor technology and high-speed tool technology, it has pushed high-speed machining into a new era. The electric spindle integrates the motor into the spindle unit. Because of its high speed, it will generate a lot of heat during operation, causing the temperature of the electric spindle to rise. Therefore, a cooling mechanism for the electric spindle that is easy to disassemble and assemble is needed to cool it down.

[0003] The traditional part of the easy-to-disassemble electric spindle cooling mechanism is to process the circulation holes or circulation grooves in the spindle outer cylinder. The cooling media such as water and oil flow through the circulation holes and grooves to complete the heat exchange and realize the cooling of the electric spindle.

[0004] The existing problem is that a part of the traditional electric spindle cooling mechanism is fixed and connected by a large number of screws during installation and use, which makes the installation or maintenance and removal process more cumbersome. For this reason, we propose an electric spindle cooling mechanism that is easy to disassemble and assemble. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide an electric spindle cooling mechanism that is easy to disassemble and assemble. A cooling pipe is opened inside the cooling component so that cooling water or cooling oil can be stably input and output, so that the heat generated by the electric spindle can be stably absorbed by the cooling component, thereby achieving stable cooling of the electric spindle. By means of stable limit card connection, the mechanism can be quickly disassembled and assembled, which is convenient for replacing or assembling the cooling component, and can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric spindle cooling mechanism that is easy to disassemble and assemble, comprising a supporting connecting cylinder, a fixing assembly and a cooling assembly;

Through stable limit card connection, the mechanism can be quickly disassembled and assembled, which is convenient for replacing or assembling the cooling assembly.

[0010] Furthermore, the fixing assembly includes a limiting hole, a limiting slide cylinder, a limiting cross block, a sliding column, a spring and a limiting circular plate.

The front end of the supporting connecting cylinder is provided with symmetrically distributed limiting holes, and the sliding columns are respectively clamped with the vertically adjacent limiting holes, so as to facilitate the rapid and stable assembly of the device.

[0011] Furthermore, the fixing assembly also includes a friction slider, which is fixedly connected to the outer surface of the limiting slide cylinder. The outer surface of the friction slider is slidably connected to the slide groove opened at the front end of the limiting circular plate, so as to facilitate the control of the limiting parts of the fixing device.

[0012] Furthermore, the cooling assembly includes a spiral cooling groove, a cooling cylinder and an I-shaped slider. The I-shaped sliders are respectively slidably connected to the inside of the I-shaped groove. A cooling cylinder is fixedly connected between the two I-shaped sliders. A spiral cooling groove is provided inside the cooling cylinder to facilitate heat exchange cooling of the electric spindle.

[0013] Furthermore, the cooling component also includes a water inlet pipe, which is fixedly connected to the water inlet opened at the front end of the cooling cylinder. The outer surface of the water inlet pipe is slidably connected to the water inlet sliding hole opened at the front end of the limiting circular plate, so as to facilitate the cooling component to input cooling water or cooling oil after heat exchange.

[0014] Furthermore, the cooling component also includes a water outlet pipe, which is fixedly connected to the water outlet opened at the rear end of the cooling cylinder.

[0015] Furthermore, it also includes connecting holes, which are evenly opened at the front end of the supporting connecting tube to achieve stable connection between the device and the electric spindle.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the electric spindle cooling mechanism which is easy to disassemble and assemble has the following advantages:

The staff slides two friction sliders to make the friction slider drive the limiting slide cylinder to move along the slide column toward the limiting circular plate. Then, the limiting circular plate is slid into the I-shaped slide groove through the limiting cross block, so that the water inlet slide hole slides along the outer surface of the water inlet pipe, so that the limiting circular plate contacts the cooling cylinder, thereby limiting the cooling cylinder. By loosening the friction slider, the limiting slide cylinder is engaged with the limiting hole under the action of the spring rebound force, so that the device can be quickly installed.
