Then, each distributor correspondingly connected with the hydraulic valve is connected to each oil adding level 611 of the grinding head assembly through a second oil distributing pipe 43 so as to quantitatively and automatically add lubricating oil to a plurality of oil adding levels 611 of the grinding head assembly. The oil is automatically supplied to the timing of the distributor according to the hydraulic valve of the first control valve group 20, and the oil is supplied to the oil supply position 611 of the grinding head assembly by the ration of each distributor, without manually opening or closing the oil supply path.
The multipoint automatic oiling system applied to the polishing equipment provided by the embodiment of the utility model has at least the following technical effects or advantages:
compared with the conventional oiling system of the polishing equipment, the manual oiling monitoring method is implemented. In the embodiment of the utility model, the automatic oiling system pumps lubricating oil to the first control valve group 20 through the oiling pump 10 along the pipeline of the main oil delivery pipe, and a plurality of hydraulic valves of the first control valve group 20 are correspondingly connected with a plurality of distributors I30 through the distributing pipe I so as to independently control an oil way on each distributor through the hydraulic valve of the first control valve group 20 and automatically convey the lubricating oil to each distributor at regular time; then, the plurality of distributors are correspondingly connected to each oiling level 611 of the grinding head assembly through the second oil distributing pipe 43, and each oiling level 611 of the grinding head assembly can be correspondingly provided with an independent distributor for quantitatively distributing oiling; so that the first control valve group 20 can automatically and regularly oil and lubricate the multiple oil adding levels 611 of the grinding head assembly under the control of the main control system, thereby improving the oil adding efficiency, avoiding the misjudgment of oil adding caused by manual monitoring oil adding in the past, reducing the labor cost and effectively avoiding the conditions of oil adding overflow, oil adding in place and oil leakage.
In the embodiment of the utility model, the type of the hydraulic valve is selected according to the requirement that the hydraulic valve used in the embodiment of the utility model is one of an electrohydraulic proportional valve, a flow dividing and collecting valve, a flow dividing valve and a flow collecting valve, and the hydraulic valve can be reasonably selected according to the oil filling condition of the oil filling level 611 of the grinding head assembly.
The distributor at least comprises a distributor I30, a distributor II 31 and a distributor III 32. As can be seen from the above description of the first control valve group 20, the first control valve group 20 is provided with at least three hydraulic valves. Therefore, by connecting the three hydraulic valves of the first control valve group 20 to the oil inlet ends of the first, second and third distributors 30, 31, 32 through the first oil delivery pipe 42, respectively; and the length of each oil distributing pipe I42 which is respectively connected with the distributor I30, the distributor II 31 and the distributor III 32 is set to be consistent.
In this way, compared to the prior art embodiments in which the petrol pump 10 pumps the grease directly to the dispenser. The automatic oiling system in the embodiment of the utility model independently controls the first distributor 30, the second distributor 31 and the third distributor 32 by utilizing the plurality of hydraulic valves of the first control valve group 20 so as to meet the independent control of each distributor; the lengths of the first oil distributing pipes 42 connected with the first distributor 30, the second distributor 31 and the third distributor 32 are consistent, so that the pipeline pressure of each first oil distributing pipe 42 is ensured to be the same; thereby enabling the first control valve group 20 to deliver the lubricating oil to each dispenser at regular time and quantity, improving the oiling efficiency and the oiling amount accuracy of the grinding head assembly.
Similarly, it is available that the length design requirements for the oil filling position 611 of the grinding head assembly and the adopted oil dividing and conveying pipe two 43 are that the lengths of the oil dividing and conveying pipes two 43 of the oil filling position 611 of the grinding head assembly, respectively connected with the first distributor 30, the second distributor 31 and the third distributor 32, are identical, so that the pipeline pressure of each oil dividing and conveying pipe two 43 is ensured to be identical.
In this way, compared with the conventional oiling system of the polishing device, the lubricating oil is uniformly distributed to each oiling level 611 of the grinding head assembly through one distributor, and the lengths of the distributed oil distribution pipes are not uniform. The automatic oiling system in the embodiment of the utility model independently controls the first distributor 30, the second distributor 31 and the third distributor 32 by utilizing the plurality of hydraulic valves of the first control valve group 20 so as to meet the independent control of each distributor; and the lengths of the oil distributing pipes II 43 which are connected to the grinding head assembly are consistent through the first distributor 30, the second distributor 31 and the third distributor 32, so that the pipeline pressure of each oil distributing pipe II 43 is ensured to be the same, the quantity of lubricating oil distributed to the grinding head assembly can be accurately controlled by each distributor, and the oiling efficiency and the oiling quantity precision of the grinding head assembly are further improved.
As can be seen from the description of the above technical solutions, the first control valve set 20 is provided with at least three hydraulic valves, and the corresponding distributor is provided with at least a distributor one 30, a distributor two 31 and a distributor three 32. Therefore, according to the design requirement that each hydraulic valve of the first control valve group 20 is correspondingly connected with one distributor, at least three oil distributing pipes 42 are needed in the embodiment of the present utility model. According to the design requirement of a distributor corresponding to a oiling position 611 connected with the grinding head assembly, in the embodiment of the utility model, at least three oil separating pipes two 43 are needed. Of course, in the case that the grinding head assembly continues to increase the oil filling level 611, a plurality of oil distributing pipes II 43 can be selectively connected to the distributor, so as to meet the oil filling and lubrication requirements of the grinding head assembly. Thus, the arrangement requirements for the number of the first branch oil pipelines 42 and the second branch oil pipelines 43 are that the number of the first branch oil pipelines 42 is larger than or equal to the number of the second branch oil pipelines 43. Therefore, the oiling and lubricating efficiency of the grinding head assembly is improved.
The oil outlet of the oiling position 611 of the grinding head assembly is provided with an oil overflow sensor, and the oil overflow sensor is electrically connected with a main control system so as to detect the oil overflow condition of the oil outlet of the oiling position 611 in real time through the oil overflow sensor, and feed back the oil overflow signal to the main control system, and the main control system sends an instruction to the oiling pump 10 and the first control valve group 20 according to the feedback signal of the oil overflow sensor so that the oiling pump 10 and the first control valve group 20 execute corresponding actions. For example, when the oil outlet overflows, the main control system controls the pumping amount of the oil filling pump 10, and the main control system controls the hydraulic valve of the first control valve group 20 to stop the filling action to the corresponding filling level 611.
In this way, by arranging the oil overflow sensor at the oil outlet of each oil filling level 611 of the grinding head assembly, in the process of filling oil into the oil filling level 611 of the grinding head assembly, the oil overflow sensor is used for sensing whether the oil filling level 611 overflows; if lubricating oil overflows, the oil overflow sensor feeds back a signal to the main control system, so that the main control system controls the oil filling pump 10 and the first control valve group 20 to stop filling the oil to the oil filling level 611 of the oil overflow, manual monitoring and filling are replaced, automatic detection of the oil filling condition of the oil filling level 611 of the grinding head assembly is realized, the problem of oil filling overflow is prevented, and the labor cost is further reduced.

The main shaft 60 is movably connected with the bearing sleeve through a bearing, for example, an upper bearing is sleeved at the upper end of the main shaft 60, and a lower bearing is sleeved at the lower end of the main shaft 60, so that the main shaft 60 is movably connected with the bearing sleeve through the upper bearing and the lower bearing; the polishing grinding head 61 is in transmission connection with the main shaft 60 through a coupling. Since parts are worn during long-term operation of the main shaft 60 and the polishing head 61, it is necessary to lubricate the movable joint with oil to reduce wear, and therefore, the oil level 611 is provided at a position corresponding to the upper bearing and the lower bearing of the main shaft 60, and the oil level 611 is provided at a position corresponding to the coupling of the polishing head 61.
