Description
Technical Field
The utility model relates to a cold pressure detection technical field in the machining digit control machine tool, concretely relates to cold system detection device in digit control machine tool.
Background
At present, most of machining centers used in factories are provided with internal cooling devices, main shafts of the machining centers are communicated with the internal cooling devices, and internal cooling systems of the internal cooling devices consist of sealed rotary joints, high-pressure cooling devices and cooling liquid filtering devices. The cooling liquid after the filter processing is carried out through the paper tape filter during machine tool machining is promoted through the high-pressure pump, and the through hole through main shaft center sends the cooling liquid to the handle of a knife and spouts through the through hole on handle of a knife and the stage property to reach the cooling to the processing work piece, be favorable to improving the incorruptibility of machining efficiency and cutter like this. However, in order to efficiently process the numerical control machine tool and ensure long-term operation of the main shaft, the hydraulic pressure value of the internal cooling device needs to be controlled within a required range, for example, the hydraulic pressure value is different in processing materials, the drilling depth is different, the feeding speed of the machine tool is different, and the required internal cooling pressure value is certainly different. However, for many enterprises, especially for engine manufacturers, only one working procedure is required for one numerical control machine. The machining center is mainly used for machining cylinder block and cylinder head hole systems, rigid tapping and surface machining, different internal cooling tools are required for cutting in the machining processes, the required internal cooling pressure is different, the corresponding internal cooling pressure value needs to be set, and the pressure is kept constant in the specified process. However, these requirements still have much uncertainty in maintaining the pressure constant. In the processing process, if the cutter is broken or the blade is broken, when whether the inner cooling system is caused by fault is checked, obviously, the reason cannot be checked only by a pressure gauge of a pump, unreliable factors exist all the time, and the possibility that the cutter is broken or the blade is broken exists
The pressure of the equipment may leak due to the failure of the pump pressure gauge, and sometimes the real pressure is not the same value although the reading is made on the pump pressure gauge. On the basis of the original technology, the inner cooling cutter can only be detached, whether the inner cooling pressure reaches the standard or not is judged by observing the strength of the sprayed water column, and the approximate and fuzzy judgment is inaccurate. When frequent cutter breakage or edge breakage occurs, slag can be discharged slowly, and the production progress is seriously influenced due to the influence of inaccurate reason analysis and the like, so that the waiting waste in time is caused. In addition, no error-proof pressure detection device can not meet the quality control requirement, and batch unqualified products are easy to occur.
The above background disclosure is only provided to aid in understanding the concepts and technical solutions of the present invention, and it does not necessarily belong to the prior art of the present patent application, and it should not be used to assess the novelty and inventive step of the present application without explicit evidence that the above content has been disclosed at the filing date of the present patent application.
