An improved indexing plate

Abstract

The invention provides an improved dividing plate, and belongs to the technical field of machinery. The improved dividing plate solves the technical problem that in the case of an existing dividing plate, lubrication is insufficient and the like. The improved dividing plate comprises a shell and a dividing rotating disc rotationally connected outside the shell, a worm wheel and worm mechanism is arranged in the shell, a mounting seat is fixed in the shell, an oil storage cavity is formed in the bottom of the mounting seat, a piston cylinder is fixed at the position, located on one side of a worm, in the mounting seat, a piston rod is arranged in the piston cylinder, a piston is fixed at the lower end of the piston rod, a driving mechanism capable of driving the piston rod to ascend and descend up and down is arranged on the mounting seat and the piston rod, the bottom of the piston cylinder is provided with an oil inlet connector and an oil outlet connector, the oil inlet connector isconnected with a first one-way valve, the oil outlet connector is connected with a second one-way valve, an oil inlet of the first one-way valve is connected with an oil inlet pipe, the other end of the oil inlet pipe is located in the oil storage cavity, an oil outlet of the second one-way valve is connected with an oil spraying pipe, and the other end of the oil spraying pipe faces the middle part of the worm wheel. The improved dividing plate has the advantage that lubricating oil between the worm wheel and the worm can be ensured to be sufficient.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an improved indexing plate. Background technique [0002] The indexing plate is a mechanism that realizes intermittent motion. It has the characteristics of high indexing accuracy, stable operation, large transmission torque, compact structure, small volume, low noise, good high-speed performance, and long life. , Incomplete gear mechanism, Qigong control mechanism and other traditional institutions are ideal products. An indexing table that uses a motor as a driving source is called an electric indexing table. [0003] The electric indexing table mainly drives the turbine and worm mechanism to rotate through the motor, and the turbine is connected with the indexing turntable to realize the indexing adjustment of the rotating position of the indexing turntable. Since the indexing turntable will be subject to circumferentially rotating torque during machine tool processing, this ...

AI Technical Summary

Problems solved by technology

Since the indexing turntable will be subject to circumferentially rotating torque during machine tool processing, this requires the indexing turntable to have a certain degree of stability after it rotates in place. The existing indexing turntable mainly realizes the worm gear by locking the motor. Rotation is locked to achieve positioning, but the index turntable will still rotate slightly when subjected to a large torque, so it is necessary to set an auxiliary brake structure on the index turntable to strengthen the stability of the index turntable. The existing index turntable There is no corresponding structure to strengthen the stability of the indexing turntable; at the same time, the worm needs lubricating oil to lubricate during transmission. The existing lubrication of the worm is mainly by immersing the lower side of the worm in lubricating oil. When the worm rotates, the lubricating oil will The oil belt is used to lubricate the turbine. This method requires a large amount of lubricating oil, and the lubricating effect is not good. It cannot ensure that there is a sufficient amount of lubricating oil at the meshing part of the turbine and the worm.
