Description

Technical Field

[0001] This utility model relates to the field of surface grinding machine technology, and in particular to a centralized and precise lubrication oil supply system for surface grinding machine guideways and lead screws. Background Technology

[0002] A surface grinder is a type of grinding machine. It primarily uses a rotating grinding wheel to grind workpieces to achieve the required flatness. Based on the shape of the worktable, it can be divided into rectangular and circular worktables. The main parameters of a rectangular worktable surface grinder are its width and length, while the main parameter of a circular worktable is its diameter. Based on the type of shaft, it can be divided into horizontal spindle grinders and vertical spindle grinders.

[0003] Existing surface grinders typically employ large-plane closed hydrostatic guideways in conjunction with lead screws to achieve large-stroke, stable, and reliable reciprocating motion of the worktable. However, after prolonged use and break-in, the friction between the guideways and lead screws gradually increases, leading to jamming and affecting the precise movement of the workpiece. Current solutions mainly involve using a lubricating gun to inject oil internally, which makes it difficult to ensure the uniformity of the lubricating oil and thus the lubrication effect. To address this, a centralized and precise lubrication system for the guideways and lead screws of surface grinders is proposed. This system features an oil groove structure that allows lubricating oil to flow across the entire guideway surface, and an oil injection hole at the lead screw nut to deliver lubricating oil to the lead screw helix surface for lubrication. Utility Model Content

[0004] This invention provides a centralized and precise lubrication system for the guide rails and lead screws of a surface grinder, which solves the problems mentioned in the background and can effectively and uniformly lubricate the guide rails and lead screws of the surface grinder, thereby ensuring that the worktable of the surface grinder can perform large-stroke, stable and reliable reciprocating motion.

[0005] The solution to the above-mentioned technical problems of this utility model is as follows: A centralized and precise oil supply system for lubricating oil for guideways and lead screws of a surface grinder includes a 2L fully automatic electromagnetic lubricating oil pump, a three-way oil distribution block, a slide oil distribution block, a 4x DPC resistance unidirectional metering element, a right-angle connector assembly, a base oil distribution block, a 2x DPC resistance unidirectional metering element, a 5x DPC resistance unidirectional metering element, an M8X1 oil pipe connector, a Φ4 lubricating oil pipe, and a surface grinder body. The 2L fully automatic electromagnetic lubricating oil pump is bolted to the surface grinder body. The base oil distribution block is connected to an oil inlet pipe connector. The 2L fully automatic electromagnetic lubricating oil pump is connected to the surface grinder body via... A Φ4 lubricating oil pipe is connected to a three-way oil distribution block. One end of the three-way oil distribution block is connected to a slide plate oil distribution block, and the other end is connected to the oil inlet pipe connector of the base oil distribution block. The Φ4 lubricating oil pipe connecting the three-way oil distribution block to the slide plate oil distribution block is covered with a spring sleeve. The slide plate oil distribution block is connected to a 4x DPC resistance unidirectional metering element and a 2x DPC resistance unidirectional metering element. The base oil distribution block is connected to a 2x DPC resistance unidirectional metering element and a 5x DPC resistance unidirectional metering element. The 2x DPC resistance unidirectional metering element is connected to a right-angle connector assembly or an M8X1 oil pipe connector via a Φ4 lubricating oil pipe.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the base oil distribution block has two 5x DPC resistance unidirectional metering elements, both of which are connected to a right-angle connector assembly. The right-angle connector assembly of the 5x DPC resistance unidirectional metering element corresponds to the vertical guide rail of the column of the surface grinder body.

[0008] Furthermore, the base oil distribution block is provided with six 2x DPC resistance unidirectional metering elements, two of which are connected to M8X1 oil pipe joints, the two of which correspond to the Z-axis lead screw nut and the Y-axis lead screw nut respectively, and four of which are fixedly connected to right-angle joint assemblies, each corresponding to the left and right base guide rails of the surface grinder body respectively.

[0009] Furthermore, the slide plate oil distribution block 3 is a five-way oil distribution block, and the base oil distribution block is a ten-way oil distribution block.

[0010] Furthermore, the M8X1 oil pipe connector is installed at the lead screw nut of the surface grinder body, and the lead screw nut uses a 2x DPC resistance type unidirectional metering element for oil supply.

[0011] Furthermore, the flat guide rail of the surface grinder body adopts a 4x DPC resistance type unidirectional quantitative metering element for oil supply.

[0012] Furthermore, the V-shaped guide rail of the surface grinder body uses two 5x DPC resistance unidirectional metering elements to supply oil to the left and right sides respectively, and the guide rail surface of the vertical guide rail of the surface grinder body uses two 5x DPC resistance unidirectional metering elements to supply oil from the left and right sides to the column guide rail surface respectively.

[0013] Furthermore, both the 4x DPC resistance unidirectional metering element and the 2x DPC resistance unidirectional metering element of the slide oil distribution block are connected to right-angle connector assemblies. The right-angle connector assembly of the 4x DPC resistance unidirectional metering element is connected to the slide guide rail of the surface grinder body, and the right-angle connector assembly of the 2x DPC resistance unidirectional metering element is connected to the V-guide rail on the slide of the surface grinder body.

[0014] This utility model provides a centralized and precise lubrication oil supply system for guideways and lead screws of surface grinders, which has the following advantages:

[0015] 1. The grinding machine guideway uses a centralized and precise lubrication oil supply system. The amount of lubricating oil is determined according to whether it is enclosed, the size of the area, and the installation posture. Different multiples of DPC resistance-type unidirectional quantitative metering elements and 2L fully automatic electromagnetic lubricating oil pumps are selected. The interval between pump starts and the number of seconds the pump works after each start are determined. This system provides precise and accurate oil supply to different lubrication surfaces, avoiding waste of lubricating oil and improving the efficiency of lubricating oil use.

[0016] 2. The grinding machine guideway uses a centralized precision oil supply system. The DPC resistance-type one-way quantitative metering element has the function of a one-way valve. The oil is only supplied to the oil outlet and will not flow back. This avoids the backflow of the lubricating oil in the high oil pipe to the oil outlet at the bottom or the oil pool of the oil pump when the oil pump is not running, thereby ensuring precise oil supply and ensuring the stable use of the surface grinder.
