Description

Automatic laminating type guide rail

Technical Field

The utility model relates to a guide rail, in particular to an automatic fitting type guide rail.

Background

The guide rail and roller set structure is ubiquitous in mechanical equipment and is a necessary structure for realizing reciprocating motion and bearing. In heavy-duty metallurgical equipment and the like, the contact stress of the guide rail and the roller is large, and the design is required to calculate the contact stress safety of the guide rail and the roller so as not to exceed the allowable contact stress of the material and quickly cause the damage of the contact surface of the guide rail and the roller. On the premise of calculating contact stress, firstly, on the structural design of a guide rail and a roller, the guide rail and the roller are required to be in comprehensive contact bearing, as in the theoretical contact condition on a design drawing, the complete line contact on the full width is required, however, in the actual condition, the shape and position errors always exist, so that the contact line of the guide rail surface and the roller surface generates an angle to form a local gap on one side, only partial width contact is adopted, the actual contact area is reduced, the local contact stress is increased, the theoretical calculation value of the material contact stress is not reliable any more, the theoretical calculation value passes, and the actual guide rail and the roller set exceed the damage result of the contact stress.

To solve the above problems, we have made a series of improvements.

Disclosure of Invention

The present utility model is directed to an automatic fitting guide rail, which overcomes the above-mentioned drawbacks and disadvantages of the prior art.

A self-conforming rail comprising: the upper part of the track assembly is connected with mechanical equipment, and the lower end of the track assembly is movably connected with the roller;

wherein the track assembly comprises: the device comprises a concave guide rail, a convex middle part, a double-head stud, a butterfly spring, an inner hexagon bolt and a limit stop, wherein the concave guide rail is connected with mechanical equipment through the double-head stud and the butterfly spring, the lower end of the double-head stud is connected with the convex middle part, the concave guide rail is connected with the convex middle part through the double-head stud, the convex middle part is connected with the mechanical equipment through the inner hexagon bolt, and the limit stop is connected with the periphery of the convex middle part.

Further, a through hole is formed in the convex-shaped middle part, and the through hole is connected with the double-end stud.

The utility model has the beneficial effects that:

compared with the prior art, the utility model has the advantages that the teeterboard structure is formed on the cross section by additionally arranging the concave guide rail and the convex middle part, the concave guide rail is driven to swing by uneven stress on two sides, and the guide rail and the roller are always and automatically attached to each other in the whole width within a certain shape error range and are comprehensively contacted and carried.

Detailed Description

The utility model will now be further described with reference to specific examples. It should be understood that the following examples are illustrative of the present utility model and are not intended to limit the scope of the present utility model.

Example 1

Fig. 1 is a top view of the present utility model. Fig. 2 is a side view of the present utility model. Fig. 3 is a schematic view of a part of the structure of the present utility model. Fig. 4 is a schematic view of the structure of the track assembly gap of the present utility model.

As shown in fig. 1 to 4, a self-conforming guide rail includes: the upper part of the track assembly 100 is connected with the mechanical equipment 300, and the lower end of the track assembly 100 is movably connected with the roller 200;

wherein the track assembly 100 comprises: the device comprises a concave guide rail 110, a convex middle part 120, a double-head stud 130, a butterfly spring 140, an inner hexagon bolt 150 and a limit stop 160, wherein the concave guide rail 110 is connected with a mechanical device 300 through the double-head stud 130 and the butterfly spring 140, the lower end of the double-head stud 130 is connected with the convex middle part 120, the concave guide rail 110 is connected with the convex middle part 120 through the double-head stud 130, the convex middle part 120 is connected with the mechanical device 300 through the inner hexagon bolt 150, and the limit stop 160 is connected with the periphery of the convex middle part 120.

The male intermediate member 120 is provided with a through hole 121, and the through hole 121 is connected to the stud 130.

The principle of the present utility model is that the concave-shaped guide rail 110 is in a teeterboard state, the concave-convex portion in the middle is contacted, and the shoulders on both sides have a gap, the concave-shaped guide rail 110 can swing, when the concave-shaped guide rail 110 contacts with one side of the roller 200 and the other side generates a gap due to shape and position errors, the center part of the concave-shaped guide rail 110, which is forced to contact with the convex-shaped middle part 120 due to the stress on one side, swings as a fulcrum until the side with the gap contacts and is in stress balance.
