Description

Technical Field

[0001] This utility model relates to the field of electric spindle technology, specifically an electric spindle for stone carving. Background Technology

[0002] An electric spindle, also known as HVCT, is a new technology in CNC machine tools that integrates the machine tool spindle and its motor. The spindle is a complete assembly, including the electric spindle itself and its accessories: the electric spindle, a high-frequency inverter, an oil mist lubricator, a cooling system, a built-in encoder, and a tool changer. This integrated transmission structure, where the spindle motor and machine tool spindle are combined, makes the spindle component relatively independent from the machine tool's transmission system and overall structure. Therefore, it can be made into a "spindle unit," commonly known as an "electric spindle" (Electric Spindle, Motor Spindle). Its characteristics include high speed, high precision, low noise, and an inner locking structure that is more suitable for spray lubrication.

[0003] Existing electric spindles used for stone carving and processing cool down using water. When the spindle temperature is high, the water evaporates, producing a lot of scale. The scale clogs the cooling tank, resulting in poor cooling efficiency of the electric spindle. Utility Model Content

[0004] The purpose of this invention is to provide an electric spindle for stone carving, which solves the problem mentioned in the background art of scale clogging the cooling tank, resulting in poor cooling efficiency of the electric spindle.

[0005] This application embodiment provides a stirring assembly fixedly connected to the support frame. The stirring assembly includes a motor disposed at the bottom of the support frame and a stirring chamber mounted at the top of the support frame. The output end of the motor extends into the interior of the stirring chamber and is fixedly connected to a transmission rod. A stirring rod is fixedly connected to the transmission rod. The interior of the stirring chamber is filled with water.

[0006] By adopting the above technical solution, water enters the mixing chamber through the inlet pipe. Workers pour triethanolamine into the graduated chamber and observe the amount added using the first graduation mark. The triethanolamine is discharged into the mixing chamber through the first valve. The drive motor rotates the transmission rod, which in turn rotates the mixing rod, stirring the water and triethanolamine to reduce scale buildup from water evaporation. Workers observe the mixing degree of water and triethanolamine through the mixing chamber. When mixing is complete and the electric spindle is in operation, the second valve is opened, allowing water to flow through the discharge pipe and telescopic pipe into the inlet and cooling tank. The cooling tank cools the electric spindle. Water then flows through the cooling tank into the spray pipe to spray the machining tools, further cooling them. Workers observe the water spray speed through the spray pipe. When the spray pipe sprays too much water, workers control the flow rate through the second valve to reduce water waste. Due to the high temperature of the electric spindle, some water will evaporate.

[0007] Optionally, each of the mixing chambers is fixedly connected to a graduated chamber and a water inlet pipe at its upper end. The graduated chamber is filled with triethanolamine, and a first valve is provided at the lower end of the graduated chamber.

[0009] Optionally, a discharge pipe is fixedly connected to the discharge end of the mixing chamber, a telescopic pipe is fixedly connected to the discharge pipe, a cooling shell is fixedly connected to the lower part of the discharge pipe, and the cooling shell is fixedly connected to the main body of the electric spindle.

[0010] By adopting the above technical solution, the mixed water is discharged into the electric spindle body, the discharge pipe is cut in the middle, and the cut end is connected to both ends of the telescopic pipe.

[0011] Optionally, a machining tool is provided at the lower end of the electric spindle body, a water inlet is provided on the cooling shell, a cooling tank is provided inside the cooling shell, a spray pipe is connected to the lower end of the cooling tank, and the water inlet is connected to the cooling tank.

[0012] By adopting the above technical solution, the water inside the cooling tank cools the main body of the electric spindle, and the spray pipe cools the machining tool.

[0013] Optionally, a second valve is provided on the discharge pipe.

[0014] By adopting the above technical solution, the second valve blocks the water flow in the discharge pipe.

[0015] Optionally, the motor is fixedly connected to the support frame, and the support frame is fixedly connected to the mixing chamber.

[0016] The motor is fixed by adopting the above technical solution.

[0017] Optionally, the outer wall of the mixing chamber is provided with a second scale value, and the inner wall of the mixing chamber is made of transparent glass.

[0018] By adopting the above technical solution, it is easier for staff to observe.

[0019] Optionally, there are multiple sets of stirring rods, and the multiple sets of stirring rods are arranged in a ring with the transmission rod as the center.

[0020] By adopting the above technical solution, the uniformity of mixing water and triethanolamine is ensured.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] The technical solution of this application uses a stirring component to mix water and triethanolamine, reducing the scale generated by the high-temperature evaporation of water. The cooling tank and spray pipe cool the machining tools of the electric spindle body, avoiding excessive scale clogging the cooling tank. Attached Figure Description

[0029] In the above technical solution, water enters the mixing chamber 201 through the inlet pipe 5. Workers pour triethanolamine into the graduated chamber 3 and observe the amount of triethanolamine added through the first graduation on the graduated chamber 3. The triethanolamine is discharged into the mixing chamber 201 through the first valve 4. The drive motor 202 drives the transmission rod 203 to rotate, which in turn drives the stirring rod 204 to rotate. The stirring rod 204 stirs the water and triethanolamine, thereby reducing scale buildup from water evaporation. Workers observe the degree of mixing between the water and triethanolamine through the mixing chamber 201. When the mixture... When the process is complete and the electric spindle body 10 is in operation, the second valve 8 is opened, and water flows through the discharge pipe 7 and the telescopic pipe 9 into the water inlet 14 and the cooling tank 15. The cooling tank 15 cools down the electric spindle body 10. The water flows through the cooling tank 15 into the spray pipe 13 to spray the machining tool 6 and cool it down. The operator observes the water spraying speed of the spray pipe 13. When the spray pipe 13 sprays too much water, the operator controls the water flow rate through the second valve 8 to reduce water waste. When the temperature of the electric spindle body 10 is high, some water will evaporate.

[0030] In the technical solution of this utility model, such as Figure 1 As shown, the upper end of the mixing chamber 201 is fixedly connected to a graduated chamber 3 and a water inlet pipe 5. The graduated chamber 3 is filled with triethanolamine.

[0033] In the technical solution of this utility model, such as Figure 3 As shown, a second valve 8 is installed on the discharge pipe 7.

[0034] By adopting the above technical solution, the second valve 8 blocks the water supply to the discharge pipe 7.

[0035] In the technical solution of this utility model, such as Figure 1 and Figure 2 As shown, the motor 202 is fixedly connected to the support frame 1, and the support frame 1 is fixedly connected to the mixing chamber 201 to fix the motor 202.

[0037] In the technical solution of this utility model, such as Figure 3 As shown, there are multiple sets of stirring rods 204, which are arranged in a ring around the transmission rod 203 to ensure uniform mixing of water and triethanolamine.

[0038] In use, water enters the mixing chamber 201 through the inlet pipe 5. The operator pours triethanolamine into the graduated chamber 3 and observes the amount added via the first graduation on the graduated chamber 3. The triethanolamine is discharged into the mixing chamber 201 through the first valve 4. The drive motor 202 rotates the transmission rod 203, which in turn rotates the stirring rod 204. The stirring rod 204 stirs the water and triethanolamine, reducing scale buildup from water evaporation. The operator observes the degree of mixing between the water and triethanolamine through the mixing chamber 201. When mixing is complete...

When the spray pipe 13 sprays too much water, the staff controls the water flow rate through the second valve 8 to reduce water waste.
