Description

Technical Field

[0001] This utility model relates to the field of hydrostatic guide rail technology, and in particular to a liquid hydrostatic guide rail oil supply device. Background Technology

[0002] Hydrostatic guideways are widely used in high-precision machine tools. The stability of the output oil pressure and temperature of the hydrostatic guideway oil supply device directly affects its running accuracy and positioning accuracy. Existing oil supply devices are mostly equipped with filters inside to filter impurities produced during the oil circulation process. However, some of these impurities are magnetic metal impurities, which have certain recycling value. Traditional oil supply devices can only process impurities centrally and cannot process magnetic metal impurities separately. At the same time, the interception effect of small magnetic impurities is poor. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hydrostatic guide rail oil supply device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A hydrostatic guide rail oil supply device includes an oil tank, one side of which is connected to an oil pump, the output end of which is connected to a magnetic filter chamber via a pipe, and one side of the magnetic filter chamber is connected to a precision filter via a pipe.

[0006] The magnetic filter chamber is equipped with a cover plate on the upper part, and multiple magnetic rods are installed at the bottom of the cover plate. A collection cover is fitted on the outside of the magnetic rods, and the collection cover and magnetic rods extend into the magnetic filter chamber.

[0007] Locking buckles are installed on both sides of the upper part of the collection cover. The locking buckles are inserted into the slots opened at the bottom of the cover plate. A notch is opened in the middle of the locking buckle, and a locking piece is locked in the notch. One end of the locking piece is connected to the adjusting rod, and the adjusting rod is rotatably installed on the upper part of the cover plate.

[0008] In addition, a preferred structure is that a return oil pipe is provided on the upper side of the oil tank, and the return oil pipe is connected to the inside of the oil tank.

[0009] Furthermore, a preferred configuration is that each of the magnetic rods is arranged in an alternating position.

[0010] In addition, a preferred structure is that adjusting rods are rotatably mounted on both sides of the upper part of the cover plate, and a locking piece is eccentrically mounted on the bottom of the adjusting rod, the locking piece extending into the slot and engaging with the locking buckle.

[0011] Furthermore, in a preferred configuration, a valve body is installed on one side of the magnetic filter chamber.

[0012] In addition, a preferred configuration is that a rubber pad is installed on the top of the slot, and when the locking buckle is inserted into the slot, the locking buckle and the rubber pad are pressed into contact.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, a magnetic filter chamber adsorbs magnetic metal impurities present in the oil, improving the interception efficiency of fine magnetic metal debris. Furthermore, through the indirect adsorption structure of the magnetic rod and the collection cover, the debris can be adsorbed onto the collection cover. The quick-release mechanism of the collection cover enables rapid disassembly and rapid recovery of impurities, effectively improving the filtration efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-6 A hydrostatic guide rail oil supply device includes an oil tank 1, one side of which is connected to an oil pump 3, the output end of the oil pump 3 is connected to a magnetic filter chamber 5 through a pipe, and one side of the magnetic filter chamber 5 is connected to a precision filter 6 through a pipe.

[0024] A cover plate 51 is installed on the upper part of the magnetic filter chamber 5, and multiple magnetic rods 53 are installed on the bottom of the cover plate 51. A collection cover 52 is fitted on the outside of the magnetic rods 53, and the collection cover 52 and the magnetic rods 52 extend into the interior of the magnetic filter chamber 5.

[0025] Locking buckles 521 are installed on both sides of the upper part of the collection cover 52. The locking buckles 521 are inserted into the slots 9 opened at the bottom of the cover plate 51. A notch is opened in the middle of the locking buckle 521, and a locking piece 71 is engaged in the notch. One end of the locking piece 71 is connected to the adjusting rod 7. The adjusting rod 7 is rotatably installed on the upper part of the cover plate 51.

[0026] A return oil pipe 2 is provided on the upper side of the oil tank 1. The return oil pipe 2 is connected to the inside of the oil tank 1 and discharges the oil overflowing from the hydrostatic guide rail into the oil tank 1.

[0027] Each magnetic rod 53 is arranged in an alternating position.

[0028] Adjusting rods 7 are rotatably mounted on both sides of the upper part of the cover plate 51. A locking piece 71 is eccentrically mounted on the bottom of the adjusting rod 7. The locking piece 71 extends into the slot 9 and engages with the locking buckle 521.

[0029] A valve body 4 is installed on one side of the magnetic filter chamber 5, and the flow of oil on one side of the magnetic filter chamber 5 is controlled by the valve body 4.

[0030] A rubber pad 8 is installed on the top of the slot 9. When the locking buckle 521 is inserted into the slot 9, the locking buckle 521 and the rubber pad 8 are pressed into contact.

[0031] A seal is provided at the connection between the collection cover 52 and the magnetic filter chamber 5 to prevent oil leakage from the inside of the chamber. The seal is provided to ensure the normal operation of the equipment. This is a conventional setting in the field and will not be explained further.

[0032] In this embodiment, the magnetic filter chamber 5 filters the oil pumped into the oil tank 1, and the magnetic attraction force generated by the magnetic rod 53 adsorbs the metallic magnetic impurities in the oil to the outer wall of the collection cover 52. Then the oil is pumped to the precision filter 6 and sent to the throttle valve for transportation.

[0033] Furthermore, after prolonged use, when maintaining the magnetic filter chamber 5, the oil flow on one side of the magnetic filter chamber 5 is cut off by closing the valve body 4, and the fasteners of the cover plate 51 are removed. The collection cover 52 is then taken out by lifting the cover plate 51. Then, by rotating the adjusting rod 51 on the cover plate 51, the locking piece 71 inside rotates and disengages from the locking buckle 521 on the upper part of the collection cover 52. At this time, the collection cover 52 can be taken out independently. During the removal process, the collection cover 52 is separated from the magnetic suction rod 52, and the magnetic impurities adsorbed on its outer side are no longer attracted by the magnetic force. The impurities can be manually recovered, for example, by brushing off the magnetic impurities and collecting them by the collection frame.

[0034] The specific methods for removing magnetic impurities from the collection shroud 52 will not be described here, as those skilled in the art are capable of doing so.

[0035] Similarly, during the installation of the collection cover 52, the collection cover 5 is placed on the magnetic stick 53, and the locking buckle 521 is inserted into the slot 9 and pressed upward to make it fully contact the rubber pad 8. At this time, the locking piece 71 is rotated to the middle of the locking buckle 521 by rotating the adjusting rod 7, thus completing the connection with the locking buckle 521.

[0036] Among them, the oil tank 1 pumps the oil from the return oil pipe 2 and the oil inside the tank through the oil pump 3, which then passes through the magnetic filter chamber 5 and the precision filter 6 in sequence.

[0037] Specifically, the precision filter 6 intercepts tiny particulate contaminants in the oil through its internal filter material. The specific model and configuration of the precision filter 6 can be purchased and used by those skilled in the art on the market.

[0038] The overall oil circulation process of the hydrostatic guide rail and its pipeline connection structure are common knowledge to those skilled in the art and will not be explained further.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
