Description

Technical Field

[0001] The invention relates to the technical field of grinding and finishing of machine tool guide rails, in particular to a new method for finishing a machine tool guide rail. Background Art

[0002] Machine tool guideways are a crucial component of machine tool structures, guiding and supporting the machine's moving parts, ensuring precise and smooth movement along predetermined paths during machining. The design and manufacturing accuracy of machine tool guideways directly impacts the overall performance and efficiency of the machine tool. Therefore, during the design and manufacturing process, guideway selection, installation, and commissioning must strictly adhere to relevant standards and requirements to ensure high precision and stability during long-term, high-load operation.

[0003] Most lathes are equipped with a slide, a runner, and a saddle, all of which must work closely together to ensure the proper operation of the lathe. Large machine tool manufacturers typically begin by machining the saddle when producing these key components. The core difficulty of the entire process lies in ensuring a zero-clearance fit between these components. When installing the saddle, some manufacturers grind the slide and the runner together to achieve a zero-clearance fit, while also manually scraping the runner. Current technical means often require a large amount of manual scraping to achieve zero-clearance fit, which is not only time-consuming and labor-intensive, but also leads to a shortage of skilled workers and difficulty recruiting workers, making it difficult for companies to find people willing to do this type of work. Summary of the Invention

The second inclined surface is provided to match the second inclined surface, the mounting groove is provided to install the slat, the slat is provided to make the components fit more closely, the first inclined surface is provided to match the first inclined surface, and the second inclined surface is provided to be at the same angle as the second inclined surface during grinding.

[0006] Preferably, the upper surface of the slide plate near the first inclined surface is a first plane, and the upper surface of the slide plate near the second inclined surface is a second plane. The first plane is provided so that it can be assembled with the lower surface of the carriage during subsequent assembly of components, and the second plane is provided so that it can be assembled with the carriage during subsequent operations.

[0007] Preferably, the upper surface of the slide plate is flat away from the first plane, and the first inclined surface and the second inclined surface are dovetail-shaped. The first inclined surface and the second inclined surface are dovetail-shaped in order to provide guidance.

[0008] Preferably, the first plane and the second plane are planes.

[0009] Preferably, the first inclined surface and the second inclined surface are dovetail-shaped.

[0010] Preferably, the two ends of the inlay strip are respectively one large and one small. The purpose of setting the two ends of the inlay strip respectively one large and one small is to compensate for wear and enhance structural stability.

[0011] Preferably, the insert is made of cast iron so as to better adapt to high friction environments.

[0012] A new method for finishing machine tool guide rails, the specific processing steps are as follows: S1. During the initial processing of the drag plate and the slide plate, you can use appropriate cleaning agents and tools to clean the surface of the drag plate and the slide plate to remove oil, iron filings, dust, etc., thereby reducing the impact of these impurities on the grinding process and reducing damage to the grinding tools.

[0013] S2. Then, the slide plate and the skateboard are placed together one after the other, and a suitable fixture is used to clamp the slide plate and the skateboard so that the first inclined surface of the skateboard and the first inclined surface of the slide plate are at the same angle, and the second inclined surface of the slide plate and the inlay are at the same angle as the second inclined surface of the skateboard. Then, a grinding tool is used to process the same plane formed by the slide plate and the skateboard at the same time.

[0014] S3. The upper surface of the skateboard corresponds to the upper surface of the drag plate, the first bevel corresponds to the No. 1 bevel, and the second bevel corresponds to the inlay and the No. 2 bevel, thereby eliminating the need for scraping.

[0015] Working principle: The surfaces of the drag plate and the slide plate are cleaned in advance to remove impurities; the drag plate and the slide plate are then clamped and fixed to ensure that the angles of the second bevel, the inlay strip and the second bevel are consistent; then the formed plane is simultaneously ground, eliminating the traditional scraping process and improving efficiency and precision.

[0016] (3) Beneficial effects The present invention provides a new method for machine tool guide rails and fine machining thereof. It has the following beneficial effects: 1. By placing and clamping the carriage and the slide plate one after the other, it is ensured that the first and second inclined surfaces of the slide plate accurately correspond to the angular positions of the first and second inclined surfaces of the carriage respectively, so that the common plane formed by the carriage and the slide plate can be directly ground, eliminating the scraping step, significantly shortening the processing cycle, and effectively improving production efficiency.

[0017] 2. Synchronous grinding ensures the consistency of the planes of the drag plate and the slide plate, improves processing accuracy and surface quality, reduces error accumulation, and ensures close fit between components. BRIEF DESCRIPTION OF THE DRAWINGS
