Description

Technical Field

[0001] This utility model relates to the field of sliding saddle technology, specifically a sliding saddle employing a stepped structure and a three-slider structure. Background Technology

[0002] The Bullhead EDM machine tool is a metal processing device that utilizes the principle of electrical discharge machining. It is primarily used for machining high-hardness materials and complex-shaped molds and parts. Its core working principle is to use electrical discharge to erode the metal surface, thereby machining the metal parts. Bullhead EDM machines are widely used for machining various high-hardness materials (such as cemented carbide and hardened steel) and complex-shaped molds and parts. Due to its non-contact machining method, it is particularly suitable for machining difficult-to-cut materials and complex-shaped workpieces. Furthermore, Bullhead EDM machines offer advantages such as high efficiency, precision, and strong adaptability, significantly improving machining efficiency and accuracy.

[0003] The structure of a bullhead EDM machine mainly includes key components such as the bed, column, worktable, slide saddle, ram, and spindle. The bed and column must possess sufficient rigidity to ensure that deformation of the machine tool during machining will not affect the discharge gap, thus ensuring smooth machining. The worktable supports and clamps the workpiece. The relative position of the electrode and workpiece is adjusted by the rotation of the lead screw on the slide saddle and the movement of the slide rail. A working fluid tank is provided to ensure that the electrode and workpiece are always immersed in the working fluid, achieving cooling and chip removal functions.

[0004] However, in the existing structure, the slide saddle located above the column has insufficient structural rigidity, resulting in unstable operation and affecting machining accuracy. Furthermore, the guide rail section needs to adopt a three-axis roller linear guide design to not only ensure high positioning accuracy but also effectively improve vibration resistance during operation. Therefore, there is an urgent need to provide a slide saddle with a stepped structure and a three-slider structure. Utility Model Content

[0005] The purpose of this invention is to provide a sliding saddle with a stepped structure and a three-slider structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sliding saddle employing a stepped structure and a three-slider structure includes a screw nut mounting seat. Slider mounting surfaces are provided on the left and right sides of the screw nut mounting seat, and sliders are mounted on these surfaces. A casting process hole is provided at the middle right side of the screw nut mounting seat, and an oil passage hole is provided at the lower right end of the casting process hole. The left side of the sliding saddle has an extension portion, and a lifting hole is provided at the front of the sliding saddle. Linear guide grooves are provided on the left and right sides of the lifting hole, and assembly process holes are provided on the upper surface of the linear guide grooves. The non-overlapping portion between the upper and lower parts of the sliding saddle is a step.

[0008] Preferably, the steps of the sliding saddle adopt a box-type stepped structure design, with the upper part recessed by 40mm on each side.

[0009] Preferably, the slide saddle is made of gray cast iron HT3000.

[0010] Preferably, the upper surface of the slide saddle has a cavity in the middle for mounting the lead screw, and cavities on both sides for mounting the slider.

[0014] 1. Provides a stable support platform: The slide saddle has high rigidity and stability, and can withstand the huge loads and impacts generated during operation.

[0015] 2. Ensure high-precision motion trajectory: Through a precision guiding mechanism and positioning system, the slide saddle can ensure that it moves along a predetermined high-precision trajectory, thereby guaranteeing the machining accuracy of the workpiece. Attached Figure Description

It is to be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. In the embodiments of the present utility model, the different types of cross-sectional lines are not labeled according to national standards, nor do they specify material requirements for the components; they are used to distinguish the cross-sectional views of the components in the drawings.

[0024] Please see Figure 1-5 A sliding saddle employing a stepped structure and a three-slider structure includes a screw nut mounting seat 1. Slider mounting surfaces 8 are respectively provided on the left and right sides of the screw nut mounting seat 1, and sliders 6 are mounted on the slider mounting surfaces 8. A casting process hole 7 is provided at the middle right side of the screw nut mounting seat 1, and an oil passage hole 9 is provided at the lower right end of the casting process hole 7. The left side of the sliding saddle has an extension 5, and a lifting hole 2 is provided at the front of the sliding saddle. Linear guide grooves 4 are respectively provided on the left and right sides of the lifting hole 2. An assembly process hole 3 is provided on the upper surface of the linear guide groove 4. The non-overlapping position between the upper and lower parts of the sliding saddle is a step 10.

[0025] The step 10 of the sliding saddle adopts a box-type step structure design, with the upper part recessed by 40mm on each side.

[0026] The sliding saddle is made of gray cast iron HT3000.

[0027] The upper surface of the saddle has a groove 11 in the middle for mounting the lead screw, and grooves 11 on both sides for mounting the slider.

[0028] The bottom surface of the sliding saddle is provided with an installation rail groove 4 that matches the upper rail of the column, and is movably connected to the column below through the rail.

[0029] The upper part of the sliding saddle extends outward by 150mm at one end.

[0030] It should be noted that the slide saddle adopts a box-type stepped structure design, which significantly improves the rigidity of the slide saddle. Compared with the traditional single-layer structure, the rigidity is increased by more than 30%. The upper layer is recessed by 40mm on each side, which effectively reduces the weight of the upper part, so that the overall center of gravity of the slide saddle is lowered, increasing the stability of operation.

[0031] The sliding saddle is made of gray cast iron HT3000, which has good casting performance, good vibration damping, good wear resistance, good machinability, and low notch sensitivity.

[0032] The upper surface of the saddle has a cavity 11 in the middle for installing the lead screw, and two cavities 11 on both sides for installing the sliders, so as to realize three-point support for the ram with the main shaft mounted above, which enhances the stability of operation. Each slider cavity is equipped with three sliders 6, which are movably connected to the ram through the sliders 6, the slide rail, and the ram.

[0033] The bottom surface is provided with an installation rail groove 4 that matches the upper rail of the column, and is movably connected to the lower column through the rail; the upper end of the slide saddle extends outward by 150mm, which effectively ensures the stability of the upper slide ram and distributes the force, reducing the possibility of slide saddle deformation, thereby extending the service life.
