Problems solved by technology

It is mainly composed of a guide rail and a slide plate. The contact surface of the slide plate and the guide rail adopts linear motion on the plane and vertical plane to ensure its horizontal and vertical motion accuracy. When this motion is subjected to gravity cutting and used for a certain period of time, due to the Various impacts and abrasions will cause the surface of the slide plate and guide rail to wear quickly, and the gap will gradually increase. The dimensional deviation of the processed product will exceed the determined minimum tolerance, and it cannot be adjusted to the original position only by the fixed guide pin There is positioning processing accuracy, which seriously affects the manufacturing quality of processed products
This is also a technical problem that the guiding device of the existing mechanical machine tools has always been eager to solve, but has not been successful.

Embodiment 1

[0013] see figure 1 , figure 2 , the slide plate 2 and the guide rail 1 are molded to cast blanks of corresponding sizes, and then washed and ground to produce finished products with the required shape and precision. The upper surface and the left and right sides of the guide rail 1 are provided with trapezoidal grooves 6, 5 , Trapezoidal convex grooves 7, 4 are provided on the slide plate 2 corresponding to the trapezoidal grooves 6, 5 on the upper surface of the guide rail 1 and the left and right sides, and the slide plate 2 and the guide rail 1 are connected by matching the trapezoidal convex grooves and the trapezoidal grooves. The slide plate 2 can slide back and forth on the guide rail 1. The shape of the trapezoidal groove is made into a trapezoidal groove with a large outer port and a small bottom port. The guide rail 1 is equipped with a lead screw, and the lead screw is connected to the slide plate 2 by bearings and bushings. , the guide rail 1 and the machine too...

Embodiment 2

[0015] In the present invention, the slide plate and the guide rail can be interchanged and used upside down, that is, a trapezoidal convex groove is arranged on the upper surface of the guide rail, and a trapezoidal groove is arranged on the slide plate corresponding to the trapezoidal convex groove on the upper surface of the guide rail. The trapezoidal convex grooves match; there are trapezoidal grooves on the left and right sides of the guide rail, and trapezoidal convex grooves are provided on the slide plate corresponding to the trapezoidal grooves on the left and right sides of the guide rail. The trapezoidal grooves match the trapezoidal convex grooves. There is a lead screw inside the guide rail, and the lead screw is connected to the slide plate with bearings and bushings. The slide plate can slide back and forth on the guide rail, and a layer of lubricating oil is applied on the contact surface of the guide rail and the slide plate to reduce the friction force between...

The mechanical guiding device features the guide rail with trapezoidal notch or trapeziodal boss in the upper surface, the slide plate with corresponding trapeziodal boss or trapezoidal notch. Compared with available technology, the present invention has the advantages of novel structure, convenient use, high precision, high work efficiency, etc.

Description

[technical field] [0001] The invention relates to the technical field of guiding devices for mechanical machine tools, in particular to a mechanical guiding device that can more effectively locate, improve guiding precision, and better withstand gravity cutting. [Background technique] [0002] At present, there are mainly two structural types of guiding devices used in existing mechanical machine tools: one is a square linear guiding device, and the other is a V-shaped linear guiding device. These two guiding devices have their own advantages, but they have one thing in common in structure, which is also the core structure in the existing mechanical guiding devices. It is mainly composed of a guide rail and a slide plate. The contact surface of the slide plate and the guide rail adopts linear motion on the plane and vertical plane to ensure its horizontal and vertical motion accuracy. When this motion is subjected to gravity cutting and used for a certain period of time, due...
