Description

Technical Field

[0001] The utility model belongs to the technical field of shock absorption of numerical control machine tools, and in particular relates to a shock absorption base for numerical control machine tools. Background Art

[0002] A CNC machine tool is an automated machine tool equipped with a program control system that can logically process programs specified by control codes or other symbolic instructions, decode them, represent them in coded numbers, and input them into the CNC device through information carriers. CNC machine tools will vibrate when in use.

[0003] For example, the Chinese patent with publication number CN218874415U discloses a shock-absorbing base for CNC machine tools, including a base, the inner wall of the base is movably connected to a support seat, the bottom of the support seat is provided with a movable groove, the inner wall of the movable groove is fixedly connected to a first crossbar, the outer wall of the first crossbar is movably connected to a first spring, the outer wall of the first crossbar is movably connected to a first slider, the front of the first slider is movably connected to a telescopic frame, and the bottom of the telescopic frame is movably connected to a second slider. The shock-absorbing base for CNC machine tools can play a role in reducing vibration when supporting the CNC machine tools, avoiding the situation where the base is single in functionality and cannot buffer and reduce shock for the CNC machine tools, effectively improving the effect and functionality of the base when supporting, and avoiding the situation where the shaking of the CNC machine tools during processing reduces the stability of the machine tools, further improving the effect of use, and meeting the needs of use.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: when this device is used to reduce the shock of the CNC machine tool, it can only reduce the shock of the CNC machine tool up and down, and the CNC machine tool will also vibrate left and right and front and back when in use, resulting in poor shock absorption effect of this device. In addition, when the CNC machine tool is in use, the amplitude of each vibration is different, so the amplitude of shock absorption required is different. In view of this, we propose a shock absorbing base for CNC machine tools. Utility Model Content

[0006] The purpose of the utility model is to provide a shock-absorbing base for a numerically controlled machine tool to solve the problems raised in the above-mentioned background technology.

[0007] In view of this, the utility model provides a shock-absorbing base for a CNC machine tool, comprising:

[0008] A shock absorbing seat, wherein a limiting groove is provided in the shock absorbing seat, a placing box is slidably installed in the limiting groove, four extrusion plates are slidably installed in the placing box, a damping rod 1 is symmetrically fixedly installed between the extrusion plates and the inner wall of the placing box, and a spring 1 is sleeved on the damping rod 1;

[0009] Two round rods, both of which are fixedly mounted on the inner wall of the limiting groove and are located below the placement box, sliding blocks are symmetrically slidably mounted on the round rods, a connecting rod is rotatably mounted between the sliding block and the bottom of the placement box, a rubber column is fixedly mounted on the round rod and located between the two sliding blocks, a tension spring is sleeved on the round rod and located on one side away from the two sliding blocks, four damping rods are fixedly mounted between the bottom of the placement box and the bottom of the limiting groove, and springs are sleeved on the damping rods;

[0010] Two rectangular blocks, both of which are slidably mounted in the limiting grooves and are located below the placement box, and a rubber block is fixedly mounted on the top of the rectangular block;

[0011] The driving assembly is located in the shock-absorbing seat and is used for driving the two rectangular blocks to rise or fall.

[0012] In the present technical scheme, by setting the placement box, when the CNC machine tool shakes or vibrates, the CNC machine tool will squeeze the placement box, so that the placement box moves downward in the limit groove, and the downward movement of the placement box will squeeze the four connecting rods to rotate. Under the cooperation of the connecting rod, the sliding block, the rubber column, the tension spring, the damping rod 2 and the spring 2, the CNC machine tool can be damped up and down. When the CNC machine tool shakes left and right or vibrates front and back, the CNC machine tool will squeeze the extrusion plate, so that the extrusion plate moves in the inner cavity of the placement box. The movement of the extrusion plate will squeeze the two damping rods 1 and the two springs 1 to contract. Under the damping action of the two damping rods 1, the CNC machine tool can be damped.

[0013] Through the set driving assembly, the driving assembly will drive the two rectangular blocks and the two rubber blocks to move upward, so as to adjust the distance between the top of the rubber block and the bottom of the placement box. At this time, when the placement box moves downward again, it will first hit the rubber block, so that the downward movement of the placement box can be stopped in advance, thereby adjusting the amplitude of shock absorption, ensuring that personnel can adjust the amplitude of shock absorption according to the amplitude of shaking or vibration of the CNC machine tool.

[0014] In the above technical solution, further, the driving component includes:

[0015] A rotating groove, the rotating groove is opened in the shock-absorbing seat and is located below the rectangular block, two worm wheels are rotatably installed in the rotating groove, the top ends of the two worm wheels pass through the top of the rotating groove and are fixedly installed with threaded rods, the top ends of the threaded rods extend into the corresponding rectangular blocks, one side of the two worm wheels and located in the rotating groove are meshed with worms, and the two worms are coaxially connected, a rocker is rotatably installed on one side of the shock-absorbing seat, one end of the rocker passes through one side of the shock-absorbing seat, extends into the rotating groove and is coaxially connected with one of the worms, the inner wall of the limiting groove and the two ends of the two rectangular blocks are respectively provided with sliding grooves, and the two ends of the rectangular block respectively extend into the corresponding sliding grooves.

[0016] In the present technical solution, personnel can rotate the joystick according to the amplitude of the shaking or vibration of the CNC machine tool. The rotation of the joystick will drive the two worms to rotate. Under the action of meshing, the rotation of the two worms will respectively drive the two worm wheels to rotate. The rotation of the two worm wheels will respectively drive the two threaded rods to rotate. Under the action of the thread, the rotation of the threaded rod will drive the rectangular block and the rubber block to move upward, thereby adjusting the distance between the top of the rubber block and the bottom of the placement box. At this time, when the placement box moves downward again, it will first hit the rubber block, so that the downward movement of the placement box can be stopped in advance, thereby adjusting the amplitude of shock absorption, ensuring that personnel can adjust the amplitude of shock absorption according to the amplitude of the shaking or vibration of the CNC machine tool.

[0018] In this technical solution, it is ensured that the rotation of the threaded rod can drive the rectangular block to move up and down, that the worm can rotate normally in the rotating groove, that one end of the rocker can rotate normally in the rotating groove, and that the rectangular block can slide normally in the sliding groove.

[0019] In the above technical solution, further, the four damping rods 2 are respectively located at the four corners of the bottom of the placement box, and the two round rods are located between the four damping rods 2.

[0025] In the above technical solution, further, the cross-section of the placement box is a T-shaped structure.

[0026] In this technical solution, it is ensured that the placement box will not fall out of the limiting groove.

[0027] The beneficial effects of the utility model are:

[0028] 1. The shock-absorbing base for the CNC machine tool has a placement box set up.
