Description

TECHNICAL FIELD

[0001] The utility model relates to a numerical control tool grinder grinding oil oil mist oil stain collector. BACKGROUND

[0002] A large amount of grinding oil is used in the operation process of the numerical control tool grinder for machining cutters, the grinding oil is sprayed to the grinding wheel and the workpiece to improve the grinding efficiency, prolong the service life of the grinding wheel and improve the grinding quality of the workpiece, but the grinding oil of most grinders is directly collected as waste oil for centralized treatment after use, which not only increases the production cost, but also wastes a lot of resources in the treatment of waste oil.

[0003] To solve the above problems, the existing recycling equipment directly uses an oil mist collector for collection, but only collects the oil mist in the production process and does not recycle the large amount of waste oil generated in the production process. Because the equipment cannot improve the filtering speed, the amount of clean oil circulated and returned is small, so it cannot meet the oil requirement of the numerical control equipment in operation, thereby affecting the use of the numerical control equipment. UTILITY MODEL CONTENTS

[0031] The lower end of the stainless steel outer cylinder 141 is provided with an oil outlet hole 1411, and the waste oil sprayed by the oil spraying pan 144 flows out from the oil outlet hole 1411 after being filtered by the filtering assembly 142 and gathered in the oil pan 13; the upper end inside the stainless steel outer cylinder 141 is integrally formed with a buckling groove 1412, which can be fixed with the cover 143.

[0032] The filtering assembly 142 comprises an outer fine filter cylinder 1421, a bottom filter plate 1422 fixed at the bottom of the outer fine filter cylinder 1421, and an inner coarse filter cylinder 1423 sleeved inside the outer fine filter cylinder 1421, and the waste oil is filtered by the inner coarse filter cylinder 1423 and then filtered by the outer fine filter cylinder 1421, which can improve the quality of waste oil filtering and meet the requirements of recycling.

[0033] The center of the cover 143 is provided with a threaded hole 1431, and the lower end side of the cover 143 is integrally formed with a buckling tooth 1431, which is convenient for fixing and installing the oil spraying pan 144, and when the cover 143 is assembled with the stainless steel outer cylinder 141, the buckling tooth 1431 is buckled into the buckling groove 1412 by rotating the cover 143, and the cover 143 is fixedly assembled with the stainless steel outer cylinder 141.

[0034] The oil inlet end of the oil spraying pan 144 is welded with a threaded pipe 1441, and the threaded pipe 1441 is screwed into the threaded hole 1431 of the cover 143 to complete the fixed installation with the cover 143, and then the pipe 1441 can be connected with the pipeline connected with the first oil pump 15.

[0036] It needs to be further explained that the purpose of setting the oil injection disc 144 is: 1. The oil injection disc 144 sprays oil to the inner coarse filter cylinder 1423 to brush the inner wall of the inner coarse filter cylinder 1423, so as to avoid impurities from being adsorbed on the inner coarse filter cylinder 1423 and causing blockage; 2. When the dirty oil is injected into the oil filtering mechanism 14 until more than half, the oil injection disc 144 sprays oil to the inner coarse filter cylinder 1423, so that the dirty oil inside the inner coarse filter cylinder 1423 is stirred, thereby improving the filtering efficiency of the dirty oil.

[0037] The oil tank body 11 is divided into an upper tank body 111 and a lower tank body 112 by the intermediate partition plate 12, and a front baffle 113 and a rear baffle 114 are respectively arranged on both sides of the upper tank body 11.

The structure of the second oil pump 16 is consistent with that of the first oil pump 15, and the second oil pump 16 is also fixed by using a mounting ring after being assembled to the intermediate partition plate 12.

[0041] The oil mist collector 2 is detachably arranged, and the output end of the oil mist collector 2 is communicated with the input end of the first oil pump 15. The dirty oil collected from the machine tool by the oil mist collector 2 is delivered to the oil filtering mechanism 14 through the first oil pump 15 for filtering treatment, and the obtained clean oil is stored in the oil pan 13.

[0042] In the embodiment, the oil mist collector 2 is a centrifugal oil mist collector with a model of GP500.

[0043] It needs to be further explained that the output end of the second oil pump 16 is communicated with the machine tool. Specifically, the dirty oil collected by the oil mist collector 2 from the machine tool is delivered to the oil filtering mechanism 14 through the first oil pump 15 for filtering treatment, and the obtained clean oil is stored in the oil pan 13. Then, the second oil pump 16 extracts and delivers the clean oil stored in the oil pan 13 to the machine tool.
