The shaft lubrication system applied to the 3D printer is described below with reference to specific embodiments to further understand the inventive concept of the shaft lubrication system applied to the 3D printer. Referring to fig. 1, in an embodiment, a shaft lubrication system 10 for a 3D printer includes: axle subassembly 100 and oil supply unit 200, oil supply unit 200 set up in one side of 3D printer, axle subassembly 100 with oil supply unit 200 is connected, oil supply unit 200 be used for to axle subassembly 100 oil supply.
In one embodiment, the shaft assembly 100 includes an X-axis 110, a Y-axis 120, and a Z-axis 130 disposed on a 3D printer and an encoder 140 disposed on each axis. Wherein the X-axis 110, Y-axis 120, and Z-axis 130 are kinematic mechanisms that carry the sand-blaster, print head, and work box of the 3D printer. Specifically, the X-axis 110 is provided with an encoder 140, the Y-axis 120 is provided with an encoder 140, and the Z-axis 130 is provided with an encoder 140. In this way, the motion of each shaft can be conveniently recorded by the encoder arranged on each shaft.

Referring to fig. 2, in one embodiment, a method for controlling a shaft lubrication system includes the following steps:
s110: starting a 3D printer for printing;
it should be noted that the shaft lubrication system of this embodiment is a lubricating oil supply system for the operating working shaft of the 3D printer, and includes a software control system and a hardware control system, where the software control structure is embedded in the operating control panel of the 3D printer, and an operator can control the operation of the lubricating oil system for the working shaft while performing 3D printing operation. It can be understood that when the 3D printer is started to print, the corresponding working axes X, Y and Z start to operate, and the shaft lubrication system can start oiling according to the operating conditions of the respective shafts at any time.
S120: collecting data of each shaft of the shaft assembly by adopting an encoder, and calculating the total movement stroke of each shaft;
in one embodiment, the step of acquiring data of each shaft of the shaft assembly by using an encoder and calculating the total movement stroke of each shaft includes: feeding back position information of each shaft of the shaft assembly by using an encoder; and calculating the total movement stroke of each shaft according to the position information of each shaft. That is, the actual position of each shaft is fed back through the encoder, and the software control system of the shaft lubrication system carries out the accumulated calculation of the total running stroke of the shaft according to the position information of the shaft. Therefore, the software control system with the encoder matched with the shaft lubricating system can be used for conveniently and quickly counting and recording the total movement stroke of each shaft.
S130: judging whether each shaft reaches the oiling standard or not according to the total motion stroke of each shaft;
in one embodiment, the step of judging whether each shaft reaches the oil injection standard according to the total movement stroke of each shaft includes: the shaft lubrication system presets an oil injection standard according to the motion condition of each shaft of the 3D printer, and sequentially judges and executes an oil injection program according to the X shaft, the Y shaft and the Z shaft; when the total running strokes of the X-axis, the Y-axis and the Z-axis detected by the encoders of the X-axis, the Y-axis and the Z-axis reach the oiling standard, the shaft lubrication system automatically triggers an oiling program of the X-axis, the Y-axis and the Z-axis. Namely, the software control system of the shaft lubrication system sets the oiling standard in advance according to the motion condition of each shaft of the 3D printer and stores the oiling standard in the software control system of the shaft lubrication system. When actual oil injection is performed, oil is respectively injected to the X-axis, Y-axis oil injection is started after the X-axis oil injection is finished, and Z-axis oil injection is started after the Y-axis oil injection is finished.
Further, the step of the shaft lubrication system automatically triggering the X-axis, Y-axis and Z-axis oiling procedures comprises: and the shaft lubricating system adjusts the size of an outlet of the corresponding distributor according to the total running stroke of the X shaft, the Y shaft and the Z shaft. In one embodiment, the distributor is a regulator valve. Therefore, the opening and closing degree of the distributor valve can be automatically adjusted through the total movement stroke of the shaft, and quantitative oil filling is realized. In one embodiment, the distributor is a reducing structure. In this way, a reasonable distribution of the amount of oil injected into the various shafts can be achieved.
In one embodiment, whether each shaft reaches the oiling standard is judged according to the total movement stroke of each shaft, and if not, each shaft continues to execute the printing work. That is, when it is detected that the total travel of each shaft does not reach the travel specified by the preset oiling standard, each shaft continues to perform the printing operation without performing the oiling operation.
S140: when the oil injection standard is judged to be reached, the lubricating oil pump is started to supply oil to the distributor of the corresponding shaft;
namely, when the total running stroke of the shaft calculated by a software control system of the shaft lubrication system according to the position information fed back by each shaft encoder reaches an oil filling standard, the oil supply assembly is started to work, oil in the oil pocket is pumped out by the lubricating oil pump to supply oil to the distributor of the corresponding shaft, and the oil is supplied to each shaft correspondingly arranged with the distributor.
S150: analyzing and judging whether the oil supply of each shaft reaches the oil supply standard, if so, stopping oil supply and resetting the encoder data.
That is, after the oil supply of the X-axis, the Y-axis, and the Z-axis is completed, the operation of the oil supply unit is stopped. At this time, the encoder data of each shaft needs to be cleared to restart counting and prepare for the next oil supply.
In one embodiment, the step of analyzing and determining whether the oil supply of each shaft meets the oil supply standard includes: and judging whether the corresponding shaft reaches the oil supply standard or not according to the pressure gauge feedback value of each branch oil pipe. Therefore, the current oil injection conditions of the X axis, the Y axis and the Z axis can be conveniently and clearly known through data feedback of each pressure gauge. It can be understood that the pressure values of the pressure gauge in the oil injection process of the X axis, the Y axis and the Z axis can present a gradually rising state, and the pressure values can not change any more until the oil is fully injected, so that the operator can conveniently stop the oil injection operation according to the data feedback values. And judging whether each shaft reaches the oiling standard or not according to the total movement stroke of each shaft, and if not, continuing to execute the printing work by each shaft.
In one embodiment, the step of analyzing and determining whether the oil supply of each shaft meets the oil supply standard includes: when the oil injection action is not executed, the shaft lubrication system automatically reports faults and feeds back oil injection information.
Specifically, whether the oil supply operation is started or not can be judged by monitoring whether the lubricating oil pump is started or not, and whether the oil supply operation is started or not can be detected by monitoring whether a pressure gauge on an oil pipe has a numerical value change or not. And a software control system of the shaft lubrication system can detect whether the oiling action is not executed or not in time by detecting the oiling information feedback condition of each shaft, and the software control system is communicated with a feedback fault report when the non-action is detected indeed and feeds back the actual oiling information so that an operator can master the current oiling condition of each shaft in time, thereby being convenient for carrying out regular quantitative oil supply on each shaft correspondingly when the system is recovered.
In one embodiment, whether oil supply of each shaft reaches the oil supply standard or not is analyzed and judged, and if not, whether the oil supply of the shaft lubrication system is normal or not is detected.
It should be noted that the condition that the oil supply of each shaft does not reach the standard is directly related to whether the operation of the oil supply assembly is normal, and therefore, whether the oil supply of the shaft lubrication system is normal, which includes whether the operation of the lubricating oil pump is normal, whether the oil pipe and the branch oil pipe are damaged, and whether the oil supply of each distributor is normal, needs to be detected. When the oil supply does not reach the standard, all the components of the whole oil supply assembly need to be checked and judged; at the same time, a check of the software control system of the shaft lubrication system is required. That is to say, the oil supply software and hardware system needs to be comprehensively checked when the abnormal phenomenon occurs in the oil supply, so that the reason for the abnormal condition can be conveniently and comprehensively judged, and the maintenance and the recovery are convenient in time.
According to the shaft lubrication system applied to the 3D printer and the control method thereof, the X shaft, the Y shaft and the Z shaft in the shaft assembly of the 3D printer are correspondingly and respectively connected into the corresponding distributors of the oil supply assembly, the total shaft movement stroke is collected and calculated through the encoders on the corresponding shafts when the shafts move, so that whether the shafts reach the oil injection standard is judged, the lubricating oil pump is correspondingly started when the oil injection standard is reached, so that the oil in the oil pocket is pumped and distributed to the corresponding distributors through the oil pipe, the regular oil supply of each shaft is realized, and the problems of overflow or incapability of oil injection and the like can be avoided.
