A method and structure for assembling a gantry slide ram

Abstract

This invention discloses a method and structure for assembling a gantry slide ram, belonging to the machine tool field. The method involves coarse positioning of the pressure plate and slide saddle via their sides, followed by fixing the pressure plate and slide saddle with a first fastener, forming an installation area between them. The fixed pressure plate and slide saddle are then machined simultaneously as a whole, forming multiple keyways. A fixing key is installed in the keyway to further secure the pressure plate and slide saddle. Using the second and third positioning surfaces of the slide saddle as references (adjacent and perpendicular), the slide ram is placed in the installation area. A strip assembly is installed in the gap between the slide ram and slide saddle, and in the gap between the slide ram and pressure plate. Through these steps, the connection strength between the pressure plate and slide saddle is high, resulting in better slide ram stability during heavy cutting; the guide rail has a longer service life, and the machining is smoother and more reliable.

Description

Technical Field

[0001] This invention relates to the field of machine tools, and in particular to a method and structure for assembling a gantry slide. Background Technology

[0002] CNC machine tools are automated machine tools equipped with a program control system. They can move and process parts according to a pre-programmed program. CNC machine tools integrate mechanical, automation, computer and microelectronic technologies, and solve the problem of machining complex and precision parts. They are flexible, high-efficiency automated machine tools with a high degree of automation, which is conducive to the modernization of production management, shortens the production cycle, and saves a lot of process equipment costs. As a structural part on the crossbeam of most machining centers, the slide saddle has a great impact on machining accuracy.

[0003] In existing technology, the pressure plate and slide saddle are fixed by pin positioning and screw locking. While this is sufficient for normal cutting, it becomes insufficient in heavy cutting, especially left-right cutting, leading to vibration and affecting machining. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, one of the objectives of this invention is to provide a gantry slide assembly method with high structural strength and high processing precision.

[0005] In order to overcome the shortcomings of the prior art, the second objective of this invention is to provide a gantry slide assembly structure with high structural strength and high processing precision.

[0006] One of the objectives of this invention is achieved through the following technical solution:

[0007] A method for assembling a gantry slide ram includes the following steps:

[0008] The pressure plate and the slide saddle are roughly positioned by the side. The pressure plate and the slide saddle are then fixed by the first fastener. At this time, an installation area is formed between the pressure plate and the slide saddle.

[0009] The fixed pressure plate and the slide saddle are treated as a whole, and the pressure plate and the slide saddle are processed simultaneously to form multiple keyways on the pressure plate and the slide saddle.

[0010] Installing a fixing key into the keyway further secures the pressure plate to the slide saddle.

[0011] Using the second and third positioning surfaces of the slide saddle as references, with the second and third positioning surfaces adjacent and perpendicular to each other, the slide ram is placed in the installation area.

[0012] A strip assembly is installed in the gap between the slide block and the slide saddle, and a strip assembly is installed in the gap between the slide block and the pressure plate.

[0013] Furthermore, the gap between the slide block and the slide saddle is parallel to the third positioning surface, and the gap between the slide block and the pressure plate is parallel to the second positioning surface.

[0014] Furthermore, both the second positioning surface and the third positioning surface are guide rail surfaces.

[0015] Furthermore, the pressure plate includes a main body and a protrusion extending from the main body, the length of the protrusion being less than the length of the main body, the slide saddle having a groove for forming the mounting area, the protrusion being located in the groove, and the edge of the protrusion forming the side for coarse positioning.

[0016] Furthermore, the first fastener is a screw.

[0017] The second objective of this invention is achieved by the following technical solution:

[0018] A gantry ram assembly structure is provided for implementing any of the above-described gantry ram assembly methods. The gantry ram assembly structure includes a saddle, a pressure plate, a first fastener, and a ram. The saddle has a sliding groove. The pressure plate and the saddle are fixed by the first fastener. An installation area is formed between the pressure plate and the saddle. Keyways are provided on both the pressure plate and the saddle.

The ram is located in the installation area. The strip assembly is installed in the gap between the ram and the saddle, and in the gap between the ram and the pressure plate.

[0019] Furthermore, the first fastener is a screw.

[0020] Furthermore, the fixed key is a flat key.

[0021] Furthermore, the pressure plate includes a main body and a protrusion extending from the main body, the length of the protrusion being less than the length of the main body, the slide saddle having a groove for forming the mounting area, the protrusion being located in the groove, and the edge of the protrusion forming a side for coarse positioning of the pressure plate and the slide saddle.

[0022] Furthermore, the slide saddle is provided with two guide rail surfaces, which are perpendicular to each other, and the two guide rail surfaces are the positioning surfaces between the slide block and the slide saddle.

[0023] Compared to existing technologies, the gantry slide ram assembly method of this invention uses a pressure plate and a slide saddle for rough positioning via the side. The pressure plate and slide saddle are then fixed using a first fastener, forming an installation area between them. The fixed pressure plate and slide saddle are then processed simultaneously as a whole, forming multiple keyways. A fixing key is installed in the keyway to further secure the pressure plate and slide saddle. Using the second and third positioning surfaces of the slide saddle as references (adjacent and perpendicular), the slide ram is placed in the installation area. A strip assembly is installed in the gap between the slide ram and the slide saddle, and in the gap between the slide ram and the pressure plate. Through these steps, the connection strength between the pressure plate and the slide saddle is high, resulting in better slide ram stability during heavy cutting; the guide rail has a longer service life, and the processing is smoother and more reliable.
