Description

Technical Field

[0001] The utility model relates to the technical field of numerical control tool holders, and more specifically, to a cooling device for a numerical control tool holder. Background Technique

[0002] Numerical control machining has more stringent requirements for aspects such as the stiffness, accuracy, durability, and dynamic balance performance of tools. The selection of tools should focus on the analysis of the structure and processability of the workpiece, and comprehensively consider factors such as the machining ability of the numerical control machine tool, the workpiece material, and the process content.

[0003] The thermal expansion and contraction tool holder expands by heating to install the tool, and then cools down to tightly clamp the tool. When disassembling, it is usually necessary to heat the tool holder again to make it expand, so as to easily remove the tool. After that, it needs to be quickly cooled back to room temperature. However, during the cooling process of the tool holder, the coolant directly contacts the tool holder for cooling, which will cause the tool holder to be subjected to thermal shock and easily cause deformation of the tool holder surface, affecting the later use of the tool holder.

In addition, the power of the air cooling mechanism 3 drives the tool holder body 8 to rotate, improving the comprehensiveness of the liquid cooling mechanism 2 in cooling the tool holder body 8. First, use the air cooling mechanism 3 to cool the tool holder body 8 for a period of time, and then cool the tool holder body 8 through the liquid cooling mechanism 2, making the cooling of the tool holder body 8 progressive. Firstly, it reduces the thermal shock of the tool holder body 8 during cooling, and secondly, it ensures the cooling efficiency of the tool holder body 8.

A transmission belt 309 is drivingly connected to the surfaces of the driving wheel 308 and the driven wheel 310.

[0025] The effects achieved by the above components are as follows: The double-axis cooling motor 302 drives the gear 303 to rotate. The gear 303 drives the gear cylinder 304 to rotate, causing the gear cylinder 304 to drive the rotating rod 306 inside it to rotate. The rotating rod 306 drives the driving wheel 308 to rotate. Under the driving action of the transmission belt 309, the driving wheel 308 drives the driven wheel 310 to rotate, and thus the driven wheel 310 drives the first rotating plate 311 to rotate, causing the tool holder body 8 to rotate, which is convenient for the liquid cooling mechanism 2 to cool the tool holder body 8 comprehensively and improves the cooling effect of the tool holder body 8.

[0026] As Figure 4 shown, a vertical plate 307 is fixedly installed at the bottom of the inner cavity of the cooling box 1. A fixed bearing is fixedly installed inside the vertical plate 307. The left side of the rotating rod 306 penetrates through the fixed bearing, and the right side of the rotating rod 306 is rotatably connected to the right side of the inner cavity of the cooling box 1.

[0027] The effects achieved by the above components are as follows: By setting up the vertical plate 307 to limit the driving wheel 308 and the driven wheel 310, it improves the stability during transmission.

[0028] As Figure 4As shown in the figure, an electric push rod 315 is fixedly installed on the left side of the second rotating plate 313, a clamping plate 314 is arranged on the right side of the second rotating plate 313, and the output end of the electric push rod 315 is fixedly connected to the clamping plate 314.

[0030] As Figure 3 shown, the liquid cooling mechanism 2 includes a liquid storage tank 201, the liquid storage tank 201 is fixedly installed on the top of the cooling tank 1, a liquid level observation port 202 is arranged on the front of the liquid storage tank 201, a liquid pump 203 is fixedly installed on the top of the cooling tank 1 and on the right side of the liquid storage tank 201, a spray plate 204 is fixedly installed on the top of the inner cavity of the cooling tank 1 and directly above the tool holder body 8, the output end of the liquid pump 203 is communicated with the spray plate 204, and the input end of the liquid pump 203 is communicated with the liquid storage tank 201.

[0031] The effects achieved by the above components are as follows: By setting the liquid storage tank 201 to store the special coolant, under the action of the liquid pump 203, the coolant inside the liquid storage tank 201 is pumped out and discharged into the spray plate 204, and then sprayed onto the surface of the tool holder body 8 through the nozzles at the bottom of the spray plate 204 to cool the tool holder body 8.

Under the action of the dust-proof net 7, it prevents dust and impurities in the air from entering the inside of the cooling tank 1 and avoids dust affecting the cooling of the tool holder body 8.

[0034] The working principle of this cooling device for a numerical control tool holder:

[0035] The biaxial cooling motor 302 drives the driving gear 303 to rotate. The gear 303 drives the gear cylinder 304 to rotate, so that the gear cylinder 304 drives the rotating rod 306 inside it to rotate. The rotating rod 306 drives the driving wheel 308 to rotate. Under the driving action of the transmission belt 309, the driving wheel 308 drives the driven wheel 310 to rotate. Thus, the driven wheel 310 drives the first rotating plate 311 to rotate, making the tool handle main body 8 rotate, facilitating the all-round cooling of the tool handle main body 8 by the liquid cooling mechanism 2 and improving the cooling effect of the tool handle main body 8. Under the action of the liquid pump 203, the coolant in the liquid storage tank 201 is pumped out and discharged into the inside of the spray plate 204, and then sprayed onto the surface of the tool handle main body 8 through the nozzles at the bottom of the spray plate 204 to cool the tool handle main body 8. Under the action of the liquid level observation port 202, it is convenient to observe the remaining amount of the coolant in the liquid storage tank 201 and facilitate timely addition.
