Description

Technical Field

[0001] This utility model relates to the field of vibration reduction technology, specifically a vibration-damping floor mat for power source equipment. Background Technology

[0002] Existing mechanical equipment with motor power sources generates significant noise during operation. For example, a rotary grinding machine uses a rotating spindle to drive the workpiece or grinding tool, resulting in a relatively simple structure used for grinding internal and external cylindrical surfaces. The rotary grinding machine has a motor that drives the spindle; the motor's noise level is 65 dB under no-load conditions. When loaded, the motor's vibration and noise increase significantly, impacting the workshop working environment and affecting the equipment's lifespan.

[0003] The rotary grinding machine is basically vertical, with the bottom of the equipment supported by four cylindrical feet, and rubber pads are fitted under the feet for vibration damping. The above technology has the following drawbacks: the rubber pads are fatigue-prone and have a short service life, which easily leads to limited vibration damping effect. Therefore, there is an urgent need for a new type of vibration damping pad structure for power source equipment. Utility Model Content

[0004] The purpose of this invention is to provide a vibration damping mat for power source equipment to solve the problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a vibration damping mat for power source equipment, the vibration damping mat includes an upper cylinder and a lower cylinder, the horizontal cross-section of the upper cylinder is smaller than the horizontal cross-section of the lower cylinder, both the upper cylinder and the lower cylinder are made of vibration damping alloy, the upper cylinder has a first through hole in the center, the first through hole is suitable for connection with the foot of the grinding machine.

[0006] Through the above technical solution, the first through hole of the upper cylinder can be used to insert a cylindrical foot, and the lower cylinder can be used to increase the area to provide more stable support. The vibration damping mat uses a twinned damping alloy, which has the function of hindering the relative motion of objects and converting kinetic energy into heat energy or other dissipable energy. Specifically, the vibration damping mat consumes the vibration force of the grinding machine through internal molecular movement.

[0007] Furthermore, the upper cylinder has several vibration damping holes on its wall surface.

[0008] Through the above technical solution, when the vibration force of the grinding machine motor is transmitted, the vibration damping hole of the upper cylinder can absorb part of the vibration force and isolate it.

[0009] Furthermore, there are four vibration damping holes, which are evenly distributed along the wall of the upper cylinder.

[0010] The above technical solution ensures that the vibration damping holes are evenly distributed, resulting in better vibration damping effect.

[0011] Furthermore, the lower cylinder has a central through hole in the middle, and a vibration damping groove is provided along the inner wall of the central through hole.

[0012] Through the above technical solution, when a more intense vibration force is transmitted to the lower cylinder, the vibration damping groove can provide deformation space and absorb the vibration force.

[0013] Furthermore, the vertical cross-section of the vibration damping groove is semi-circular.

[0014] The above technical solution allows for easy slotting of the semi-circular shape and facilitates the absorption of vertical vibration forces.

[0015] Furthermore, a first side hole and a second side hole are provided on both sides of the first through hole.

[0016] With the above technical solution, when the grinding machine's feet are inserted, the first and second side holes provide loosening space. When the grinding machine is working, the first and second side holes can isolate a portion of the vibration force transmitted by the feet.

[0017] Furthermore, the lower surface of the upper cylinder is provided with a symmetrical first slot and a second slot, and the first horizontal center line L1 where the first side hole and the second side hole are located is perpendicular to the second horizontal center line L2 where the first slot and the second slot are located.

[0018] Through the above technical solution, the first slot and the second slot can alleviate the force when the grinding machine's feet are inserted, and release a certain amount of vibration force when the grinding machine is working.

[0020] 1. This utility model uses a vibration-damping floor mat made of vibration-damping alloy material, which has the advantages of long service life and good vibration reduction effect;

[0021] 2. This utility model absorbs and isolates vibration force through the vibration damping holes in the upper cylinder and the vibration damping grooves in the lower cylinder, thereby achieving the effect of vibration reduction and noise reduction;

Detailed Implementation

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0030] Example 1

[0031] like Figure 1 As shown, Embodiment 1 discloses a vibration-damping mat for power source equipment, which reduces the vibration noise generated during the operation of a grinding machine. The vibration-damping mat 1 is made of a vibration-damping alloy, which can absorb the vibration force transmitted by the grinding machine, thereby reducing noise.

[0032] Based on the above, such as Figure 1-3 The vibration-damping mat 1 includes an upper cylinder 11 and a lower cylinder 12, which are integrally formed. The upper cylinder 11 has a first through hole 111 for inserting the feet of a grinding machine. A first side hole 113 and a second side hole 114 are provided on both sides of the first through hole 111, providing deformation space for easy insertion of the feet. The lower surface of the upper cylinder 11 has symmetrical first slots 115 and second slots 116. The first horizontal center line L1, where the first side holes 113 and second side holes 114 are located, is perpendicular to the second horizontal center line L2, where the first slots 115 and second slots 116 are located. This allows the first and second slots to alleviate the force exerted when the grinding machine feet are inserted from different angles and to release a certain amount of vibration force when the grinding machine is operating.

[0033] Based on the above, the lower cylinder 12 has a central through hole in the middle, and the horizontal cross-section of the lower cylinder 12 is larger than the horizontal cross-section of the upper cylinder 11, which makes the support stable.

[0034] Based on the above, in order to achieve a better vibration reduction effect, the wall surface of the upper cylinder 11 is provided with a plurality of through-holes 112. In this embodiment, there are four vibration reduction holes 112, which are evenly distributed along the wall surface of the upper cylinder 11. The vibration reduction holes 112 can isolate the vibration force transmitted by the grinding machine to the ground, reducing noise generation. The number of vibration reduction holes 112 is not limited to four, and can also be other numbers, such as two. The shape of the vibration reduction holes 112 can be circular, oblong, square, etc.

[0035] Meanwhile, a vibration damping groove 121 is provided around the inner wall of the lower cylinder 12 along the central through hole. In this embodiment, the vertical cross-section of the vibration damping groove 121 is semi-circular. When the grinding machine transmits a more intense vibration force to the lower cylinder 12, the vibration damping groove 121 can undergo slight deformation to absorb and isolate the vibration force, preventing the vibration force from being transmitted to the ground and reducing noise generation. The shape of the vibration damping groove 121 is not limited and can also be square, etc.

[0036] The operating principle of this embodiment is as follows: When the grinding machine is working, the vibration force of the grinding machine motor is transmitted to the vibration damping mat 1. The vibration damping mat 1 absorbs and isolates the vibration force based on its own material, vibration damping holes 112, and vibration damping grooves 121, thereby reducing vibration noise. This utility model is applicable to all mechanical equipment with a power source and can be used as a vibration damping mat for these mechanical equipment.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No markings in the claims should be construed as limiting the scope of the claims.
