Description

Technical Field

[0001] This utility model belongs to the field of machining center technology, specifically relating to a shock-absorbing base for a five-axis machining center. Background Technology

[0002] Machining centers, due to their high-precision machining requirements, are extremely sensitive to vibration. Vibration can lead to machining errors and shorten equipment lifespan, thus requiring vibration-damping bases to suppress their own and external vibrations. As machining centers become increasingly high-speed, heavy-duty, and precision-oriented, vibration issues become more prominent, driving the development of vibration damping technologies. Existing technologies are mostly based on traditional materials and structures, which have limitations in adaptability and stability, prompting the development of new solutions.

[0003] Ordinary shock-absorbing bases have poor versatility in terms of structure, and it is difficult to adapt fixed parameters to different equipment. They are prone to over- or under-damping, and some are large in size, requiring modification for installation. In terms of materials, rubber is greatly affected by the environment and has weak high-frequency suppression, springs are prone to resonance and fatigue, and composite materials are expensive and have poor stability.

[0009] As a preferred embodiment of the present invention, the shock-absorbing component further includes a circular groove formed in the side wall of the rubber pad, the circular groove being fitted onto the side wall of the buffer disc.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0018] Example Reference Figure 1-5 This is an embodiment of the present invention, which provides a vibration damping base for a five-axis machining center, comprising: The shock absorption assembly 100 includes a base 101, a sponge pad 102 disposed on top of the base 101, a shock absorption chamber 103 disposed on top of the sponge pad 102, a rubber pad 104 disposed on top of the shock absorption chamber 103, and a shock absorption plate 105 disposed on top of the rubber pad 104.

[0019] Specifically, the base 101 is placed on a flat ground, with a sponge pad 102 placed in the middle to reduce vibration. A shock-absorbing chamber 103 is placed on the sponge pad 102, and a rubber pad 104 is placed on the shock-absorbing chamber 103. The rubber pad 104 is used to isolate the debris generated during processing and to provide partial shock absorption. A shock-absorbing plate 105 is placed on top of the rubber pad 104. All parts are not fixedly installed, which facilitates quick replacement and installation.

[0020] The damping assembly 100 also includes a buffer plate 106 fixedly connected to the bottom of the damping plate 105, and a vibration guide pin 107 fixedly connected to the bottom of the buffer plate 106; The damping assembly 100 also includes a square sand chamber 108 opened on the top of the damping chamber 103, and a vibration guide plate 109 fixedly connected to the side wall of the damping chamber 103.

[0021] Furthermore, the bottom of the damping plate 105 is fixedly connected with a buffer plate 106 and a vibration guide pin 107. The bottom of the buffer plate 106 contacts the sand in the square sand bin 108, the vibration guide pin 107 is embedded in the sand in the square sand bin 108, and the vibration guide plate 109 is inserted into the sand stored in the long sand bin 110 to transmit vibration and eliminate vibration.

[0022] The buffer disc 106 and the vibration guide pin 107 pass through the circular slot 111, and the buffer disc 106 and the vibration guide pin 107 are movably connected to the inside of the square sand bin 108.

[0023] Preferably, the circular groove 111 is fitted onto the side wall of the buffer cake 106, and the buffer cake 106 and the vibration guide pin 107 pass through the circular groove 111 to contact the sand stored in the sand bin 108. The circular groove 111 protects the sand from contamination by debris generated during processing.

[0024] The top of the shock-absorbing plate 105 is provided with an anti-slip groove, and the four shock-absorbing components 100 form a group.

[0025] It should be noted that the bottom of the machining center contacts the damping plate 105 on the top of the damping component 100, so as to eliminate the vibration of the machining center. The top of the damping plate 105 is provided with a protective groove to make the machining center more stable when working. Different numbers of damping components 100 can be placed on the bottom of the machining center to accommodate different sizes of machining centers.

[0026] In use, a fixed amount of sand is placed into the square sand bin 108 and the long sand bin 110. Then, the base 101, sponge pad 102, shock-absorbing bin 103, rubber pad 104 and shock-absorbing plate 105 are stacked in sequence. The required number of shock-absorbing components 100 are placed at the bottom of the machining center. When the machining center is working, the vibration is transmitted downwards in sequence and is transmitted to the sand stored in the square sand bin 108 and the long sand bin 110 through the buffer plate 106, the vibration guide nail 107 and the vibration guide plate 109 for elimination.

[0027] In summary, vibration is eliminated by inserting the buffer plate 106, vibration guide nail 107, and vibration guide plate 109 into the sand storage bins 108 and 110. The bulk characteristics are fully adaptable, and it is compatible with light and heavy-duty equipment and equipment with different speeds without adjusting parameters, avoiding over- or under-damping. The sand is minimally affected by temperature and oil, and the rubber pad 104 effectively prevents the sand from being contaminated by external impurities. The elasticity decay of the sand over long-term use is negligible, and the raw materials are readily available and inexpensive. High-frequency vibration suppression is more stable. The structure is extremely simple, directly utilizing the space at the bottom of the equipment without modification. There is no fixed natural frequency, which avoids resonance at the source. The load is evenly distributed, greatly improving safety and reducing costs.
