Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a static pressure guide rail structure of a vertical lathe workbench. Background Art

[0002] Currently, the guide rails of the rotary table of heavy-duty vertical lathes all use hydrostatic guide rails. The rotary table guide rail surface is inlaid with wear-resistant liners, which are composed of multiple wear-resistant liners forming an annular belt. Irregular joints are inevitably formed at the joints of the wear-resistant liners. These joints are filled with glue during production to prevent high-pressure oil leakage. The glue ages and peels off. During equipment operation, the high-pressure oil is frequently and alternatingly impacted over a long period of time, causing the glue filling in the joint to peel off and fall off, causing the pressure oil to leak from both ends of the joint. As the glue falls off more, the pressure gradually decreases, and the buoyancy also gradually decreases. The falling glue causes the guide rail to be scratched. In severe cases, there is no buoyancy, the table stops rotating, and the machine tool eventually stops working.

[0003] In view of the problems existing in the above-mentioned prior art, it is very necessary to research and design a new type of static pressure guide rail structure for a vertical lathe workbench to overcome the problems existing in the prior art. Summary of the Invention

[0004] In response to the technical problems of the colloid filling the irregular joints between adjacent wear-resistant linings proposed in the above-mentioned prior art, which delaminates and falls off after long-term use, causing guide rail wear and, in severe cases, reduced buoyancy, until there is no buoyancy at all and the machine tool cannot operate, a static pressure guide rail structure for a vertical lathe workbench is provided. The utility model mainly installs closed saddle screws at both ends of the gap between two adjacent wear-resistant linings to seal the gap into an oil cavity instead of filling with colloid, thereby avoiding the glass shedding caused by long-term use of colloid, causing guide rail and wear-resistant lining wear and even causing machine tool shutdown and other adverse consequences.

[0005] The technical means adopted by this utility model are as follows:

[0014] Furthermore, a plurality of wear-resistant lining plates are assembled into an annular structure, and the annular structure is arranged opposite to the base guide rail.

[0015] Furthermore, an irregular gap is left between two adjacent wear-resistant liners;

[0016] Furthermore, both ends of the gap are processed with countersunk screw holes;

[0017] Furthermore, a screw is assembled in the countersunk screw hole;

[0018] Furthermore, a workbench oil chamber with an open bottom is formed between the two adjacent wear-resistant liners and the screws at both ends of the gap.

[0019] Furthermore, the screw is a countersunk screw, and a force-applying portion is processed on the top of the countersunk nut;

[0020] Furthermore, the force applying portion is processed with a groove;

[0021] Furthermore, the force applying portion is ground off after the screw is assembled.

[0022] Compared with the prior art, the utility model has the following advantages:

[0023] 1. The utility model provides a static pressure guide rail structure for a vertical lathe workbench, which uses screws to seal both ends of the wear-resistant lining seam, making it firm and durable, with a long service life;
