[0002] With the rapid development of my country's machinery industry, the application of CNC gantry milling machines is becoming more and more widespread. At the same time, higher and stricter requirements are being placed on the precision of machine tools. The ram is a key functional component of CNC gantry milling machines. Its structure directly determines the rigidity and dynamic characteristics of the ram. A reasonable ram structure can have better rigidity and dynamic characteristics, thereby affecting the overall performance of the machine tool.

[0003] Conventional gantry machining center slides lack rigidity and are prone to significant deformation during high-torque cutting. Furthermore, traditional slide dimensions are mostly fixed and cannot be adjusted according to usage requirements. Therefore, a new type of slide for CNC gantry machining centers is proposed to address these technical issues. Utility Model Content

This solves the problems of insufficient rigidity of slides in general gantry machine tools, which easily leads to large deformation during high-torque cutting. Furthermore, the dimensions of traditional slides are mostly fixed and cannot be adjusted according to usage requirements.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned purpose of having strong rigidity and being able to adjust the length according to usage requirements, this utility model provides the following technical solution: a slide ram for a CNC gantry machining center, comprising a slide ram, wherein the left and right side walls of the slide ram are provided with first connecting grooves, the left and right side walls of the slide ram are provided with second connecting grooves located behind the first connecting grooves, the inner wall of the slide ram is provided with reinforcing components, the rear side of the inner wall of each of the two first connecting grooves is provided with a connecting component extending to the front side of the slide ram, and the rear side of the inner wall of each of the two second connecting grooves is provided with threaded through holes opened on the slide ram;

[0015] Compared with the prior art, this utility model provides a slide for a CNC gantry machining center, which has the following beneficial effects:

[0016] 1. The slide of this CNC gantry machining center, through the setting of a reinforcing component, is designed with a combination of rectangular reinforcing rib seats, first reinforcing rib plates, and second reinforcing rib plates, forming a three-dimensional grid-like support frame inside the slide. The first reinforcing rib plates are distributed along the top, bottom, and sides of the slide, dividing the slide cross-section into multiple closed cavities, thereby effectively improving the overall bending stiffness. The eight second reinforcing rib plates are distributed radially in a ring around the reinforcing column, effectively resisting torsional deformation caused by cutting forces. The torsional stiffness is significantly improved compared to the traditional single-layer rib plate structure. The setting of the damping alloy layer can avoid fatigue fracture caused by resonance in the rigid structure. The setting of the titanium nitride coating can reduce fretting wear on the surface of the second reinforcing rib plates, thereby giving the slide strong rigidity and improving the practicality of the device.

[0017] 2. The slide of this CNC gantry machining center, by setting up a connecting assembly, firstly, unscrew the limit nuts and washers on the two connecting threaded shafts on the outside of the first slide. Then, align the two connecting threaded shafts on the front side of the first slide with the threaded through holes on the rear side of the second slide. Rotate the two connecting threaded shafts through the two threaded through holes until the two connecting threaded shafts are screwed into the interior of the second connecting groove. Finally, screw the limit nuts and washers onto the two connecting threaded shafts. Thus, the length can be adjusted according to the usage requirements, further improving the practicality of the device. Attached Figure Description

The reinforcing column 43 is located inside the rectangular reinforcing rib seat 41.

[0026] In summary, the slide of this CNC gantry machining center, through the setting of the reinforcing component 4, which is a combination of rectangular reinforcing rib seat 41, first reinforcing rib plate 42, and second reinforcing rib plate 44, forms a three-dimensional grid-like support frame inside the slide 1. The first reinforcing rib plate 42 is distributed along the top, bottom, and sides of the slide, dividing the slide cross-section into multiple closed cavities, thereby effectively improving the overall bending stiffness. The eight second reinforcing rib plates 44 are radially distributed in a ring around the reinforcing column 43, effectively resisting torsional deformation caused by cutting force. The torsional stiffness is significantly improved compared to the traditional single-layer rib plate structure. The setting of the damping alloy layer can avoid fatigue fracture caused by resonance in the rigid structure, and the setting of the titanium nitride coating can reduce fretting wear on the surface of the second reinforcing rib plate 44, thus giving the slide 1 strong rigidity performance. This improves the practicality of the device. By setting the connecting component 5, firstly, the limiting nuts 52 and washers on the two connecting threaded shafts 51 on the outside of the first slide 1 are unscrewed. Then, the two connecting threaded shafts 51 on the front side of the first slide 1 are aligned with the threaded through holes 6 on the rear side of the second slide 1. The two connecting threaded shafts 51 are rotated to pass through the two threaded through holes 6 until the two connecting threaded shafts 51 are screwed into the interior of the second connecting groove 3. Finally, the limiting nuts 52 and washers are screwed onto the two connecting threaded shafts 51. Thus, the length can be adjusted according to the usage requirements, further improving the practicality of the device. This solves the problem that the rigidity of the slides of general gantry machine tools is insufficient, and large deformation is easily generated during high torque cutting. Secondly, the traditional slide dimensions are mostly fixed and cannot be adjusted according to the usage requirements.
