Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a split motor mount for high heat dissipation CNC machine tools. Background Technology

[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, and represent them with coded numbers. These codes are then input into the CNC device via an information carrier. After processing, the CNC device issues various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings. CNC machine tools are important tools for human production and labor, and also an important indicator of the level of social productivity development. The motor is a crucial component in CNC machine tools; therefore, a CNC machine tool drive motor mount is provided.

[0003] However, the structure of current motor mounts is relatively simple. When the motor is running, it generates heat, but the motor mount does not have a heat dissipation function. This makes it difficult for the motor to dissipate heat during operation, which can easily lead to the motor overheating and running overload, causing failure. Utility Model Content

The end of the screw rod is connected to a rocker wheel. A guide rod is axially slidably inserted through the guide hole. The guide rod is horizontally fixed between the fixed block and the support block.

[0007] As a further description of the above technical solution: the water circulation mechanism includes a water pump installed in the water tank, and two water pipes are provided in the water tank. One of the water pipes is connected to the water pump. Both water pipes pass through the water tank and through the sleeve hole. Both water pipes pass vertically through the fixing block. Each of the blind holes is connected to one of the water pipes.

The fixed block 6 has two mirror-symmetrical blind holes 21 horizontally opened on its side. The water circulation mechanism is connected to the two blind holes 21. Each blind hole 21 is movably connected to a sleeve 23. The outer edges of the two sleeves 23 are radially penetrated by a water hole 22 that is connected to the water circulation mechanism. Both sleeves 23 are connected to the hollow block 17. The top surface of the fixed block 6 is movably connected to a limiting member. The limiting member movably passes through the blind hole 21 and is connected to the two sleeves 23. The water circulation mechanism includes a water pump 18 installed in the water tank 2. The water tank 2 is provided with two water pipes 19. One of the water pipes 19 is connected to the water pump 18. Both water pipes 19 pass through the water tank 2 and through the sleeve hole 20. Both water pipes 19 pass vertically through the fixed block 6. Each blind hole 21 is connected to a water pipe 19. The cooling plate 5 is a metal block with an internal cavity and is filled with liquid nitrogen. A replenishment valve that is connected to the cavity is horizontally fixed on the rear side of the cooling plate 5.

[0021] To facilitate quick assembly and disassembly of the water circulation structure and hollow block 17, the limiting component includes a countersunk hole 27 that radially penetrates the inner wall of the blind hole 21, a connecting rod 28 that is movably connected to the countersunk hole 27, a positioning block 25 that is fixedly connected to the end of the connecting rod 28, a positioning groove 24 that is radially opened on the outside of the sleeve 23, the positioning block 25 that is movably connected to the positioning groove 24, a spring 26 that is sleeved on the outer edge of the connecting rod 28, a limiting block 7 that is fixedly connected to the top surface of the connecting rod 28, the limiting block 7 that abuts against the top surface of the fixing block 6, the top surfaces of the two limiting blocks 7 that together fix a top plate 8, the top plate 8 that is movably connected to the top surface of the fixing block 6, a first threaded hole 9 that is vertically penetrated through the center of the top surface of the top plate 8, a first bolt 10 that is threaded through the first threaded hole 9, and the end of the first bolt 10 that is rotatably connected to the top surface of the fixing block 6;

[0022] The top surface of the base 1 is fixedly connected to the support block 13. The side of the hollow block 17 is horizontally connected to the second threaded hole and the guide hole respectively. Neither the second threaded hole nor the guide hole is connected to the interior of the hollow block 17. The threaded screw 12 is threaded through the second threaded hole. One end of the screw 12 is horizontally rotatably connected to the side of the fixed block 6, and the other end is rotatably connected through the support block 13. The end of the screw 12 is connected to the rocker wheel 14. The guide rod 15 is axially slidably connected through the guide hole. The guide rod 15 is horizontally fixed between the fixed block 6 and the support block 13.

[0023] By movably connecting the hollow block 17 on the base 1, the motor body 11 is placed on the hollow block 17. A water tank 2 with an internal water circulation mechanism is fixed on the side of the base 1, and the water circulation mechanism is connected to the hollow block 17. This cools down the heat generated by the motor body 11 during operation and prevents the motor from overheating and causing overload.

[0024] Working principle: During operation, the water pump 18 draws water from the water tank 2 and sends it through one of the water pipes 19 to the blind hole 21. The water entering the blind hole 21 enters the sleeve 23 through the water hole 22 on the sleeve 23. The water in the sleeve 23 then enters the hollow block 17. The heat generated by the motor body 11 during operation is transferred to the hollow block 17 through the mounting plate 16. The water in the hollow block 17 absorbs the heat and returns to the water tank 2 through the other sleeve 23 and the water pipe 19. When the water in the hollow block 17 returns to the water tank 2, it is cooled by the cooling plate 5 before returning to the water tank 2. When it is necessary to disconnect the hollow block 17 from the water tank 2, simply turn off the water pump 18, then rotate the first bolt 10. The first bolt 10 drives the top plate 8 to rise through the first threaded hole 9. The top plate 8 drives the limit block 7 to rise. The limit block 7 drives the positioning block 25 to rise through the connecting rod 28. At the same time, the spring 26 is compressed, and the positioning block 25 retracts from the positioning groove 24 into the countersunk hole 27. Then rotate the rocker wheel 14, which drives the screw 12 to rotate. The screw 12 drives the hollow block 17 to move through the second threaded hole, so that the hollow block 17 drives the sleeve 23 to leave from the blind hole 21.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
