Description

Technical Field

[0001] This utility model relates to the field of bearing production, and in particular to a constant temperature supply equipment for coolant in bearing steel ball grinding. Background Technology

[0002] Existing bearing steel ball grinding processes generally employ open-loop coolant circulation systems, whose temperature control relies on natural environmental heat dissipation or simple cooling devices. This results in significant coolant temperature fluctuations, making it difficult to meet the stringent requirements of constant temperature environments for high-precision grinding. Furthermore, this temperature instability can easily lead to uneven distribution of residual stress on the steel ball surface, poor dimensional accuracy, and low grinding efficiency. Some cooling devices control the temperature by adding cooled coolant to the circulating hot coolant and stirring it. However, stirring with a single stirring mechanism for a short time can easily cause uneven heat exchange between the hot and cold coolants, making it difficult to control the output coolant temperature. Stirring the coolant for a long time is time-consuming and makes it difficult to achieve multi-stage stirring and cooling operations.

[0003] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

The segmented cooling mechanism 2 includes a first cooling tank 21, a second cooling tank 23, and a third cooling tank 24. Three liquid inlet pipes 13 are respectively inserted into the first cooling tank 21, the second cooling tank 23, and the third cooling tank 24. An electric butterfly valve 22 is fixedly connected to the liquid inlet end on one side of the first cooling tank 21. An electric butterfly valve 25 is fixedly connected to the bottom of the first cooling tank 21, the second cooling tank 23, and the third cooling tank 24. The electric butterfly valve 25 is connected to the interior of the first cooling tank 21, the second cooling tank 23, and the third cooling tank 24. A fixedly connected and connected conveying pipe 26 is provided between the first cooling tank 21, the second cooling tank 23, and the third cooling tank 24. A pipeline pump 27 is installed inside the conveying pipe 26.

[0027] Each of the cooling tanks 21, 23, and 24 is fitted with a cover plate 31 by bolts. Each of the cover plates 31 is fitted with a handle 32 by bolts. Each of the cooling tanks 21, 23, and 24 is fitted with an insulation jacket 28. A temperature detector 29 is fitted with a temperature detector 29 by bolts. The temperature detector 29 has a probe 30 fixedly connected inside. The probe 30 is inserted into the cooling tanks 21, 23, and 24 to monitor the temperature of the coolant in the cooling tanks 21, 23, and 24 in real time.

[0028] The electric butterfly valve 25 below the cooling tank 24 is equipped with a fixedly connected liquid outlet pipe 34. The liquid outlet pipe 34 is equipped with a fixedly connected metering pump 2 35. The cover plate 31 on the cooling tank 23 is fixedly mounted with a mounting bracket 33 by bolts.

[0029] The working process and principle of this utility model are as follows:

The above steps are repeated to further cool the coolant in cooling tank 23. Then, the pipeline pump 27 between cooling tank 23 and cooling tank 3 24 is started to pump the coolant in cooling tank 23 into cooling tank 3 24. The above steps are repeated to cool the coolant in cooling tank 3 24 to the temperature required for equipment processing. At this time, the metering pump 2 35 is started to pump the constant temperature coolant in cooling tank 3 24 to lubricate the bearing steel balls being ground.
