Description

Technical Field

[0001] The utility model relates to a tool turret cooling device for a double-spindle machining center, belonging to the technical field of tool turret cooling for a double-spindle machining center. Background Art

[0002] The dual-spindle machining center utilizes biaxial movement, lateral and longitudinal, to position the workpiece and cutter head for processing. The cutter head is also in the form of a collection of multiple cutter heads, which can meet the needs of various workpiece processing technologies, improve the processing efficiency of the workpiece, and better meet the market demand for different processing technologies. However, when the cutter head processes the workpiece, the contact surface often causes a short circuit in the machine due to high temperature, affecting the processing. The traditional cooling method is to cool the surface of the processed workpiece, which cannot move with the movement of the cutter head. The cooling position is single and the cooling effect is poor.

[0003] Existing dual-spindle machining centers can only cool the surface of the workpiece being machined. For example, the spindle cooling device of a CNC machining center disclosed in publication number CN215200998U is provided with an annular condensation layer so that the double-layer bidirectional circulation of the condensation layer can quickly flow to cool the moving axis, but it cannot move and cool down with the movement of the cutter head. The practicality is poor, and the cooling efficiency of a single cooling method is lower than the cooling efficiency of two methods, such as the cooling method of superimposed liquid cooling and air cooling.

[0004] Therefore, it is necessary to invent a turret cooling device for a dual-spindle machining center to solve the above problems. Utility Model Content

[0028] A turret cooling device for a dual-spindle machining center, wherein a clamping member 2 can be slidably connected to a No. 1 guide rail 1, and a workpiece to be processed is clamped in the clamping member 2. The device comprises a double knife body 3, a circulating pump 4, a water tank 5 and an air cooling system 6. The double knife body 3 can be slidably connected to a No. 2 guide rail 301, and a knife body base 302 is fixedly connected to the double knife body 3. A plurality of knife heads 303 and a temperature alarm module 304 are arranged on the knife body base 302. The knife body base 302 is fixedly connected to the circulating pump 4, and a soft water pipe 402 is connected between the circulating pump 4 and the water tank 5. The coolant transported in the soft water pipe 402 flows out from the liquid outlet pipe 403 through the circulating pump 4, and the liquid outlet pipe 403 corresponds to the position of the knife head 303 close to the clamping member 2.

[0029] During the entire process of machining the workpiece, the position where the cutter head 303 contacts the workpiece surface can be cooled by the coolant and by the air cooling system 6. When the temperature is too high, the temperature alarm module 304 will sound an alarm, and the temperature of the cutter head 303 at high speed will be monitored in all directions.

[0030] The bottom of the circulation pump 4 is fixedly connected to the plug rod 401, which can be inserted into the blade base 302 and engaged therewith, and a plurality of balls are arranged on the plug rod 401 to facilitate the insertion or removal of the plug rod 401 from the blade base 302.

[0031] The circulation pump 4 can be quickly and conveniently installed and removed from the blade base 302 by using the insertion rod 401 and the ball bearing, and regular maintenance of the 4 can be more conveniently performed.

[0032] The water tank 5 is filled with coolant, and the position of the water tank 5 is higher than the circulation pump 4 , and the volume of the air cooling system 6 is larger than the volume of the water tank 5 .

[0033] The coolant in the water tank 5 can be smoothly transported to the circulation pump 4 at a lower position.

[0034] A slot 602 is opened in the air cooling system 6, and an air outlet pipe 603 can be inserted into the slot 602. The air outlet pipe 603 can be inserted into the slot 602 and a magnet 604 is installed at the end of the slot 602. The magnet 604 fits tightly with the magnetic block 601. The air outlet pipe 603 is in a 7 shape, and its bottom end corresponds to the bottom end of the liquid outlet pipe 403. The bottom of the air outlet pipe 603 can be fixed with the liquid outlet pipe 403 cable tie.

[0035] The function of the air cooling system 6 is to use the air outlet pipe 603 to blow cold air toward the cutter head 303 and the surface of the workpiece being processed to cool down.

[0040] Refer to the instruction manual Figure 3-5 When the present invention is used, when the temperature of the cutter head 303 of the double-knife body 3 continues to rise during the processing, it needs to be cooled. At this time, the coolant in the water tank 5 will be transported to the circulation pump 4, and will flow out from the liquid outlet pipe 403, and will be continuously sprayed on the cutter head 303 and the workpiece surface to cool them down (under the action of the soft water pipe 402, the sliding position of the cutter body base 302 in the second guide rail 301 will not affect the liquid transportation);

[0041] At the same time, the cold air transported in the air cooling system 6 will be transported to the position of the cutter head 303 and the surface of the workpiece along the air outlet pipe 603, and dual cooling of air and liquid will be performed.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
