Description

Technical Field

[0001] This utility model relates to the field of bolster technology, specifically to a bolster with an L-shaped nesting structure. Background Technology

[0002] Electrical discharge machining (EDM) is widely used in mold manufacturing, automotive manufacturing, aerospace, aviation, and military industries. In recent years, some mid-to-high-end EDM machine tools, both domestically and internationally, have adopted a bullhead slide ram structure, where the worktable is fixed and the spindle head moves in the X and Y directions via the slide ram.

[0003] When an EDM machine tool is working, the spindle performs servo motion. Due to the large instantaneous speed and acceleration of the spindle servo motion, a significant inertial force is generated. Simultaneously, a pressure difference is generated around the electrodes immersed in the working fluid during machining. When the machining area of ​​the electrodes is large and the depth of the machining cavity is deep, the pressure difference exerts a significant and varying resistance on the electrodes. Inertial force, gravity, and pressure resistance cause the ram, which is in a suspended state, to vibrate during variable speed motion, thereby reducing the spindle's motion accuracy and performance. Furthermore, ram vibration also affects the lifespan of the X and Y direction guideways. Therefore, it is necessary to improve the ram and urgently requires a ram with an L-shaped nested structure. Utility Model Content

[0004] The purpose of this invention is to provide a slide block with an L-shaped nesting structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A ram with an L-shaped nested structure includes a ram body. The right end of the ram body is a spindle mounting end face, which is provided with a spindle mounting screw hole and a wiring mounting hole. The bottom surface of the ram body is provided with a linear guide mounting groove, which is movably connected to the saddle via the linear guide. The left side of the ram body is a counterweight balance block to ensure balanced support at the bottom of the ram body. The interior of the ram body is provided with several reinforcing ribs to enhance the overall load-bearing strength of the ram body. The front of the ram body is provided with weight-reducing holes.

[0007] Preferably, the ram body adopts an L-shaped nested structure with a middle partition rib and longitudinal, transverse and diagonal cross-shaped reinforcing ribs.

[0008] Preferably, the main shaft mounting end face of the slide body is connected to the main shaft through an interference fit and fastening bolts to improve the positioning accuracy and installation stability of the main shaft.

[0009] Preferably, the rail mounting groove is a "T" shaped groove structure, which facilitates quick positioning and replacement between the ram and the rail.

[0010] Preferably, the reinforcing ribs inside the ram body are arranged in a cross pattern, and some have a honeycomb-like distribution structure.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The present invention adopts an L-shaped nested structure for the ram: the L-shaped nested structure with a middle partition rib and longitudinal, transverse and diagonal cross-shaped reinforcing ribs ensures the structural strength and stability, reduces the structural weight, and makes the ram have better load-bearing stability in use, resulting in higher precision and more stable products.

[0021] Please see Figure 1-6 A ram with an L-shaped nested structure includes a ram body 7. The right end of the ram body 7 is a spindle mounting end face 5, which has a spindle mounting screw hole 6 and a wiring mounting hole. The bottom surface of the ram body 7 has a linear guide mounting groove 3, which is movably connected to the saddle via the linear guide. The left side of the ram body 7 has a counterweight balance block 1 to ensure balanced support at the bottom of the ram body 7. The interior of the ram body 7 has several reinforcing ribs 4 to enhance the overall load-bearing strength of the ram body 7. The front of the ram body 7 has weight reduction holes 2.

[0022] Among them, the main body 7 of the ram adopts an L-shaped nesting structure with a middle partition rib and longitudinal, transverse and diagonal cross-shaped reinforcing ribs.

[0023] The spindle mounting end face 5 of the slide body 7 is connected to the spindle through an interference fit and fastening bolts to improve the spindle positioning accuracy and installation stability.

[0024] Among them, the rail mounting groove 3 is a "T" shaped groove structure, which facilitates quick positioning and replacement between the ram and the rail.

[0025] Among them, the reinforcing ribs 4 inside the ram body 7 are arranged in a cross pattern, and some have a honeycomb distribution structure.

[0026] It should be noted that the ram adopts an L-shaped nested structure with a middle partition rib and longitudinal, transverse and diagonal cross-shaped reinforcing ribs 4 to ensure structural strength and stability, reduce structural weight, and make the ram have better load-bearing stability in use, resulting in products with higher precision and stability.

[0027] The spindle mounting end face 5 of the ram body 7 is connected to the spindle via an interference fit and fastening bolts to improve the spindle positioning accuracy and installation stability. The linear guide mounting groove 3 has a "T" shaped groove structure, which facilitates quick positioning and replacement between the ram and the linear guide, and is fixed by bolt locking to ensure guiding accuracy. The reinforcing ribs 4 inside the ram body 7 are arranged in a cross pattern, and some have a honeycomb distribution structure, which effectively improves the ram's resistance to deformation under high load conditions. The counterweight balance block 1 is custom-formed according to the weight distribution of each installation part of the ram body 7 and is cast from high-density alloy material to optimize the overall center of gravity and reduce structural vibration. The cross-shaped reinforcing ribs have hollow through holes in the middle, which facilitates the wiring holes to be laid through the internal structure of the ram, improving the safety and convenience of internal wiring.
