Detailed Description

In order to further understand and appreciate the structural features and advantages of the present invention, preferred embodiments and the accompanying drawings are described in detail as follows:

as shown in fig. 1-4, a mechanical follow-up self-lubricating sliding table comprises an upper sliding table 1, a lower sliding table 2 and a screw rod 3, wherein the upper sliding table 1 and the lower sliding table 2 are slidably connected through two guide rails arranged on the lower sliding table 2, the screw rod 3 is arranged on the lower sliding table 1 and is positioned between the two guide rails, the screw rod 3 drives the upper sliding table 1 to move in both directions back and forth through a power source, an automatic lubricating device 4 is further arranged on the upper sliding table 1, the automatic lubricating device 4 comprises a plunger oil pump 401 and a lubricating oil pipe 402, the plunger oil pump 401 is arranged on the end face of one end of the upper sliding table 1 and is arranged close to the outer side, the plunger oil pump 401 is provided with an oil pump piston rod 403, the oil pump piston rod 403 is vertically arranged downwards and is connected with the lower sliding table 2 through a connecting eccentric brake assembly 5, a rail lubricating oil channel (not shown in the figure) is arranged in the upper sliding table 1, one end of the lubricating oil pipe 402 is connected with the oil pump plunger piston 401, the other end is connected with a track lubricating oil channel. The eccentric brake assembly 5 comprises an eccentric gear 501 and a rack 502, the eccentric gear 501 is connected with the lower end of an oil pump piston rod 403 through a mandrel 503, the rack 502 is arranged on the side surface of the lower sliding table 2 through an installation connecting strip 503, the eccentric gear 501 is meshed with the rack 502, and along with the movement of the upper sliding table 1, the eccentric gear 501 is driven to move along the tooth surface of the rack 502, so that the oil pump piston rod 403 is pushed to vertically move, and lubricating oil in the plunger oil pump 401 is automatically output.
