[0002] The lubrication method and grease selection of machine tools are determined based on a comprehensive assessment of the structure of the machine tool, the degree of automation, the working conditions of the machine tool and the requirements for precision. Machine tool lubrication must strive to avoid temperature rise and vibration while meeting the requirements of reducing wear and consumption. Machine tools, as complex and precise machines, will use a variety of transmission devices. Depending on the type of equipment, working environment and the required precision requirements, there are different requirements for the viscosity, oily antioxidant properties, extreme pressure resistance and other related properties of the lubricant.
[0003] Due to the large changes in load and speed of the guide rail, and the frequent repetitive movements of the guide rail, traditional lubrication equipment uses covering lubrication, which is prone to local oil penetration to the edge of the guide rail due to excessive oil feed, thereby easily causing the guide rail active structure to creep due to boundary lubrication.

DETAILED DESCRIPTION
[0019] See also Figure 1-3 , the embodiments of the utility model are further described;
[0020] An automatic lubrication device for a lathe slide rail comprises a rail rod frame 1, a mounting angle seat 3 is fixed at one end of the rail rod frame 1, a lubrication plate 2 is plugged into the mounting angle seat 3, the lubrication plate 2 is embedded in the upper surface of the rail rod frame 1, and an inner groove is formed in the middle of the lubrication plate 2, at least two valve pipes 10 communicating with the inner groove are embedded in the lubrication plate 2, and the two valve pipes 10 are relatively symmetrically distributed, a liquid storage tank 9 is also provided between the two valve pipes 10, and the liquid storage tank 9 is externally connected to an expansion hose 8 at the end of the mounting angle seat 3;
[0021] An oil box 4 is fixedly provided on one side of the mounting angle seat 3 relative to the rail frame 1, and a liquid supply pipe seat 5 and an electric pump 6 are inserted on the oil box 4, and a transfer pipe 7 is externally connected between the liquid supply pipe seat 5 and the expansion hose 8.
[0022] The lubricating device uses an integrally fixed mounting angle seat 3 and a lubricating plate 2 as an assembly and fixing structure of a rail rod frame 1, wherein the rail rod frame 1 serves as a slide rail structure, and the inner groove formed on the surface of the lubricating plate 2 and the rail rod frame 1 serves as a contact end surface between the oil and the guide rail slide. When working, the oil in the oil box 4 is compressed mainly through the timed braking of the electric pump 6, so that the oil is output to the liquid storage tank 9 along the liquid supply pipe seat 5 and the expansion hose 8, and indirectly penetrates through the top of the valve seat 10 to the lubricating plate 2, and contacts and lubricates the guide rail slide.
[0023] Compared with the existing lubrication equipment, the device can ensure the lubrication effect of the oil spraying out from the surface of the lubrication plate 2 and contacting the guide rail slide through the inner groove structure of the lubrication plate 2, while avoiding the excessive oil from penetrating from the contact surface to the edge of the guide rail to cause boundary lubrication, thereby ensuring the lubrication effect and stability of the lubrication equipment. At the same time, the excess oil can flow back to the lubrication plate 2 and the liquid storage tank 9, so that the hydraulic pressure changes during the subsequent oil feed can be synchronized with the liquid supply lubrication, saving the oil consumption during the lubrication operation.
[0024] Preferably, a concave tube disc 11 is provided on the side edge of the connecting end between the valve tube 10 and the lubrication plate 2. The concave tube disc 11 and the inner edge of the lubrication plate 2 form an embracing clamping structure. The concave tube disc 11 uses the embracing clamping structure to ensure the effective contact area between the oil output end of the valve tube 10 and the contact end of the lubrication plate 2, that is, to ensure the lubrication effect when the oil contacts the guide rail slide during oil supply.
[0025] Preferably, Figure 2 As shown, a plurality of side through holes are formed through the side edges of the connecting ends of the concave tube disc 11 and the lubricating plate 2, and a step surface is formed between the side through hole and the inner groove of the lubricating plate 2. The side through hole serves as a side through structure between the lubricating plate 2 and the concave tube disc 11, and the relatively formed step surface is used to laterally guide the excess oil filled in the inner groove of the lubricating plate 2 to flow back to the liquid storage tank, so as to facilitate the recovery and circulation of the oil.
[0026] Preferably, the transfer tube 7 is a tapered tube structure, and the diameter of the expansion hose 8 is relatively smaller than the diameter of the transfer tube 7, so that the expansion change of the expansion hose 8 during oil supply is adapted to the hydraulic change when the oil passes through, and the relatively matching tapered structure of the transfer tube 7 is used to adapt the diameter of the expansion hose 8, so that the oil flow rate is limited by the reduced tube diameter, thereby maintaining a stable flow rate during oil feeding.
[0027] Preferably, a suction pipe 12 is arranged between the liquid supply pipe seat 5 and the oil box 4, and a check valve mouth pipe 13 connected to the suction pipe 12 is arranged through the connection end of the liquid supply pipe seat 5 with the transfer pipe 7, so that the suction pipe 12 and the check valve mouth pipe 13 relatively suspended in the oil box 4 can indirectly output the oil compressed into the liquid supply pipe seat 5, and the check valve mouth pipe 13 is used based on the valve mouth structure of the check valve to avoid the backflow of oil in the pipe section from the transfer pipe 7 to the liquid supply pipe seat 5 when the oil feeding is subsequently stopped, thereby ensuring the stability of the supply amount during each intermittent oil feeding.
[0028] Preferably, the electric pump 6 and the suction pipe 12 are relatively symmetrically distributed, and the pump port of the electric pump 6 is relatively higher than the pipe port of the suction pipe 12. The relative height difference between the electric pump 6 and the suction pipe 12 can ensure that the electric pump 6 compresses the oil in the oil box 4 to the upper end, and the oil at the bottom of the oil box 4 is output from the suction pipe 12, thereby ensuring the stability of the oil compression supply.
[0029] The implementation method of the device is that when working, the oil in the oil box 4 is compressed by the timed braking of the electric pump 6, so that the oil is output to the liquid storage tank 9 along the suction pipe 12, the check valve port pipe 13, the transfer pipe 7, and the expansion hose 8. As the oil is fed, the oil in the liquid storage tank 9 will penetrate through the concave coil 11 on the top of the valve seat 10 to the lubricating plate 2, and contact and lubricate with the guide rail slide. The remaining oil will flow back to the liquid storage tank 9 through the concave groove structure of the lubricating plate 2 and the concave coil 11 to provide lubrication during subsequent oil feeding.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
