Description

Combined guide rail structure

Technical Field

The utility model relates to a carpenter's bench saw technical field specifically is a modular guide rail structure.

Background

Woodworking table saws, which are common machines in woodworking machines, are a device that places wood on a table and pushes it back and forth to rotate a blade to cut the wood.

The material baffle mechanism is an important component of the woodworking table saw, and is used for continuously performing linear correction on materials at each cutting angle of the saw blade through the baffle arranged above the worktable, preventing the materials from deviating in the cutting process, accurately controlling the cutting width of the materials by adjusting the distance between the baffle and the saw blade, and improving the cutting speed of wood.

The distance between the material baffle and the saw blade is the width of the cut wood board. The user needs boards with different widths, and the distance between the material baffle and the saw blade can be adjusted at will. The common method at present is that a round guide rail parallel to the working table surface is arranged beside the working table, and a material baffle can slide along the guide rail to realize the function of distance adjustment;

however, the guide rail structure in the prior art is provided with one guide rail structure, the length of the guide rail structure is fixed and unchangeable, the guide rail structure does not have adjusting capability, the requirements of wood cutting of different widths cannot be met, boards cut by some users are large, and the guide rail of the material baffle is expected to be long. Some users cut the board to be small, and hope that the guide rail of the material baffle is shorter. Therefore, two types of saws, namely a long guide rail and a short guide rail, appear, and users can choose and purchase the saws according to requirements.

A user who purchases a short rail table saw will buy a long rail table saw again if he wants to reprocess a large-sized plate. The users who buy the long guide rail table saw have some waste of occupied space if the large-size plate is not processed for a long time.

This problem has not been solved well, and therefore, the present application intends to provide a guide rail assembly structure that can be adjusted to meet the requirements of practical work.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a modular guide rail structure to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a modular guide rail structure, contains main guide rail, extension guide rail, nut, clamping screw, adjusting screw, main guide rail all is equipped with first screw hole with the outer disc of extension guide rail, first screw hole and clamping screw and nut cooperation, main guide rail one end is equipped with the notch cuttype hole, and has offered the second screw hole on the outer disc of the tip that main guide rail was equipped with the notch cuttype hole, and extension guide rail one end is the step shaft, and the step shaft corresponds the setting with the step hole, and the step shaft inserts in the step hole, adjusting screw screws in the second screw hole, and adjusting screw keeps the fixed of step shaft.

Preferably, the stepped inner hole is matched with the extension guide rail in shape, the inner diameters of the inner holes are phi B and phi C, the phi C is larger than phi B, and a second threaded hole penetrates through the outer circular surface of the guide rail to the inner hole surface where the phi C is located.

Preferably, the outer diameter of the stepped shaft is equal to Φ B.

Preferably, the second threaded hole is provided as a stepped hole.

Compared with the prior art, the beneficial effects of the utility model are that:

when the machine needs a short guide rail, only the main guide rail is installed. When the machine requires a long guide rail, the main guide rail and the extension guide rail are installed at the same time. And the state conversion of the long guide rail and the short guide rail is realized. The installation is extremely simple, the operation is easy, and the method is very suitable for selecting and using the molding equipment.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution:

the utility model provides a modular guide rail structure, contain leading rail 1, extend guide rail 2, nut 3, clamping screw 4, adjusting screw 5, leading rail 1 all is equipped with first screw hole with the outer disc of extending guide rail 2, first screw hole and clamping screw 4 and nut 3 cooperation, 1 one end of leading rail is equipped with the notch cuttype hole, and offered the second screw hole on leading rail 1 is equipped with the outer disc of the tip of notch cuttype hole, 2 one end of extension guide rail are the shoulder shaft, the shoulder shaft corresponds the setting with the shoulder hole, the shoulder shaft inserts in the shoulder hole, adjusting screw 5 screws in the second screw hole, adjusting screw 5 keeps the fixed of shoulder shaft.

The shape looks adaptation of notch cuttype hole and extension guide rail 2, and the internal diameter of hole is Φ B and Φ C respectively, and Φ C > Φ B, and 4 second screw holes run through to Φ C on the excircle face of guide rail, and the external diameter of step shaft equals Φ B on the hole face that Φ C belonged to, and the second screw hole is the shoulder hole setting.

The tail end stepped shaft of the extension guide rail 2 penetrates into the tail end stepped hole of the main guide rail 1, and the main guide rail 1 and the extension guide rail 2 are basically concentric through phi B with consistent hole diameter; 4 adjusting screws 5 are arranged in 4 second threaded holes on the outer circular surface of the main guide rail 1, and the tail ends of the adjusting screws 5 are propped against the extension guide rail 2. Because phi C > phi B, the extension guide rail 2 can be finely adjusted by adjusting 4 adjusting screws 5, so that the extension guide rail 2 and the main guide rail 1 are completely concentric, and machining errors are corrected.

When the machine needs a short guide rail, only the main guide rail 1 is installed. When the machine requires a long guide rail, the main guide rail 1 and the extension guide rail 2 are installed at the same time. Therefore, the state conversion of the long guide rail and the short guide rail is realized.
