Description

Technical Field

[0001] The utility model relates to the field of shock-absorbing bases, in particular to a CNC machine tool base with high-efficiency shock-absorbing effect. Background Art

[0002] CNC machine tools can effectively reduce the processing time and auxiliary time of parts. The spindle speed and feed rate of CNC machine tools have a wide range, allowing the machine tools to perform powerful cutting with large cutting volumes. CNC machine tools are entering the era of high-speed processing. The rapid movement and positioning of CNC machine tool moving parts and high-speed cutting processing have greatly improved productivity. In addition, when used in conjunction with the tool magazine of the machining center, continuous processing of multiple processes can be achieved on one machine tool, reducing the inter-process turnover time of semi-finished products and improving productivity.

[0003] In the prior art, for example, a shock-absorbing base for a CNC machine tool with Chinese patent number CN216939394U includes a base, first spring damping rods are symmetrically fixedly connected to the top walls of the base on both sides, the top walls of the two first spring damping rods are fixedly connected to the same mounting plate, a sliding mechanism is arranged in the middle of the top wall of the base, a rotating mechanism is arranged on the bottom wall of the mounting plate, mounting seats are fixedly connected to the four corners of the top wall of the mounting plate, and threaded rods are fixedly connected to the bottom walls of the base on both sides.

[0004] However, in the prior art, although the above patent has the above technical advantages, the disadvantage is that although the above patent can achieve shock absorption for the machine tool, when the machine tool is clamping the workpiece, the machine tool will generate an instantaneous impact force when it is collected. At this time, the shock-absorbing base is instantly compressed and then rebounds when it is impacted. At this time, the instantaneous reverse impact force may cause harm to the staff, and the shock-absorbing strength of the above patent is constant and cannot be adjusted. If the shock absorption is too soft, a little impact force will cause the machine tool to fluctuate up and down. Utility Model Content

[0010] Preferably, the upper surface of the inner partition is fixedly connected to the lower surface of the top plate, the outer surface of the limit plate is fixedly connected to the bottom end of the support spring, the outer surface of the outer plate is fixedly connected to the limit block, the outer surface of the limit block is slidably connected to the outer surface of the limit plate, and the combination of the inner partition and the outer protective plate prevents foreign matter from entering.

[0011] The beneficial effects of the utility model are as follows:

[0012] 1. The utility model sets a piston.

A support spring and an inner spring are fixed below the top plate. The support spring plays a main shock-absorbing role, and the inner spring plays an auxiliary shock-absorbing role. A support column is connected below the top plate, and a piston is connected below the support column. The piston slides in the inner cover, and hydraulic oil is arranged in the inner cover.

A baffle slides in the outer cover, and a resistance spring is arranged above the baffle. Under the elastic action of the resistance spring, the influx of the hydraulic oil is reduced, thereby offsetting the impact force, achieving double shock absorption, and can reduce the impact force, thereby solving the problem that traditional equipment can only reduce shock.

[0024] Working principle:

[0025] When in use, the base 1 is installed on the ground and the top plate 4 is installed under the machine tool. When the machine tool vibrates during operation, the rotation of the machine tool is transmitted to the equipment through the top plate 4. A support spring 3 and an inner spring 14 are fixed under the top plate 4. The support spring 3 plays a major shock-absorbing role, and the inner spring 14 inside plays an auxiliary shock-absorbing role. An inner partition 12 and an outer guard plate 13 are provided between the top plate 4 and the limit plate 15. The inner partition 12 slides in the outer guard plate 13 with the movement of the top plate 4. At the same time, an inner plate 17 slides in the outer plate 2. Double-layer protection is used to isolate external debris from entering the interior, thereby affecting the operation of the equipment.

[0026] The limiting plate 15 slides on the surface of the outer plate 2, and a limiting block 16 is fixed on the surface of the outer plate 2. A groove is opened on the surface of the limiting plate 15. The limiting plate 15 is inserted into different positions of the limiting block 16 to adjust the different heights of the limiting plate 15, thereby adjusting the different elastic strengths of the support spring 3.

[0027] A support column 5 is connected to the bottom of the top plate 4, and a piston 6 is connected to the bottom of the support column 5. The piston 6 slides in the inner cover 8, and hydraulic oil is provided in the inner cover 8.

The hydraulic oil enters the outer cover 7 through the guide hole 10, and a baffle 11 slides in the outer cover 7. A resistance spring 9 is provided above the baffle 11. Under the elastic action of the resistance spring 9, the influx of the hydraulic oil is slowed down, thereby offsetting the impact force. When the impact force of the machine tool on the top plate 4 disappears, under the elastic action of the resistance spring 9, the hydraulic oil is pressed back into the inner cover 8 through the baffle 11, so that the piston 6 drives the support column 5 to reset.
