[0002] Machine tools refer to machines used to manufacture machines and machinery. They play a major role in the modernization of the national economy. Lathes are machines that mainly use turning tools to perform turning processing on rotating workpieces. Drills, reamers, reamers, taps, dies and knurling tools can also be used on lathes for corresponding processing. Lathes are mainly used to process shafts, discs, sleeves and other workpieces with rotating surfaces. They are the most widely used type of machine tools in machinery manufacturing and repair factories. The quality of the machine tool itself directly affects the quality of the machines manufactured. There are many aspects to measure the quality of a machine tool, but the main ones are good processability, high degree of serialization, generalization, standardization, simple structure, light weight, reliable operation, high productivity, etc., so that the flexibility of bearings and gears will be reduced after long-term use. Machine tool lubrication includes lubrication of bearings, gears, guides and tips; machine tool grease includes: hydraulic oil, hydraulic guide oil and lubricating oil. Different types of machine tools and working conditions have different requirements for the performance of lubricants, so lubricating oil is needed to lubricate bearings, etc. Secondly, a locking device is required when the lubrication pipeline is docked.

[0003] However, when the existing machine tool lubrication device is in use, lubricating oil is usually poured into the lubrication holes opened on the bearing shaft and the gear to lubricate the bearing shaft. Under the operation of this lubrication method, the lubricating oil will overflow, thereby causing the lubricating oil flow to be diverted, affecting the cleanliness of the device's table.

[0004] Therefore, it is necessary to invent a machine tool lubrication connection engaging device to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a machine tool lubrication connection clamping device to solve the problems raised in the above background technology.

[0007] Preferably, a mounting seat is fixedly mounted on one end of the sheath, a thread is formed on the outer wall surface of the mounting seat, and a bottom groove is formed on the outer wall surface of the sheath.

[0008] Preferably, the inner wall of the bottom trough is movably connected with a butt joint pipe, the other end of the butt joint pipe is fixedly mounted with an oil filling pipe, and the lower end of the oil filling pipe is sleeved with a first sealing ring.

[0009] Preferably, the second sealing ring is made of "silicone" material, and the second sealing ring is movably connected to the first connecting piece.

[0010] Preferably, the inner wall of the sleeve is movably connected with a bearing, and the other end of the bearing is provided with a shaft sleeve.

[0011] Preferably, a connecting block is fixedly mounted on the upper end of the sheath, a damping reset rod is disposed on one side of the connecting block, and a limiting block is mounted on the other end of the damping reset rod.

[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0013] Through the arrangement of the first connecting piece, the second sealing ring, the second connecting piece and the screw, the first connecting piece is installed at the upper end of the oil filling pipe, so that after the oil filling pipe and the sheath are installed, the pipeline for conveying lubrication can be connected between the second connecting piece and the first connecting piece installed on the oil filling pipe, which is convenient for quickly installing the oil filling pipe and the oil delivery pipe, and improves the convenience of installing the lubrication device. Secondly, the arrangement of the second sealing ring can seal the gap at the connection between the oil filling pipe and the oil delivery pipe to prevent the lubricating oil from overflowing through the gap;

[0014] By setting the connecting block, the damping reset rod and the limit block, the setting of the connecting block can fix the damping reset rod and the sleeve, so that after the oil filling pipe is connected to the bottom groove opened on the surface of the sleeve, the damping reset rod and the limit block can limit and fix the oil filling pipe, which plays a shock-absorbing role for the vibration generated when the oil filling pipe is used, thereby improving the stability of the oil filling pipe in use.
