Description
Technical Field
The invention relates to the technical field of polishing equipment, in particular to a vibration reduction tool for polishing a workpiece.
Background
The hand-held workpiece polishing operation belongs to the operation of contacting the workpiece to be vibrated, is an important hand-transmitted vibration operation, widely exists in the industries of hardware, sports equipment manufacturing (such as golf club head) and clothing manufacturing, and is an indispensable link in the production process flow of enterprises. The prior hand-held workpiece fine polishing operation, such as golf club head polishing operation, comprises the following main operation contents: the polishing operator holds the workpiece to be polished by fingers, contacts the workpiece with the abrasive belt rotating at high speed, continuously adjusts the polishing angle of the workpiece by fingers, and continuously adjusts the strength and the polishing angle according to the feeling of the fingers, so that the workpiece achieves the polishing and brightening effects.
The vibration receiving part of the fine polishing operation is mainly a finger, which is obviously different from the traditional vibration receiving operation, can generate resonance, and is easy to cause occupational arm vibration diseases and harm the health of operators; second, the metal work piece tends to be very thin, the polishing vibration is slightly careless, and the workpiece is extremely easy to discard. Even if an operator wears common anti-vibration gloves, the anti-vibration glove is not suitable for hand-transmission vibration protection of the fine polishing operation of the golf head, and the vibration reduction effect is not obvious. Because the vibration-proof glove is widely applied to the protection articles of the traditional vibration-receiving operation, the traditional vibration-receiving operation is mainly operated by a handheld vibration tool, such as a feller, a rock drill, a grinding tool and the like, the vibration-receiving part is mainly the palm center, the requirements on the flexibility and the sensitivity of the finger are not high, and the vibration-proof glove is different from the operation mode of finely grinding the handheld workpiece, so that the vibration-proof protection effect of the traditional vibration-proof glove on the finger is not obvious. Furthermore, the grip strength of a sander can be increased after the vibration-proof glove is worn, so that the sander is easy to fatigue and strain of skeletal muscles; meanwhile, after the vibration reduction glove is worn, the movement of fingers of a sander is limited to a certain extent, and the production efficiency is reduced; in addition, the vibration-proof glove is easily worn and expensive. In summary, the conventional anti-vibration glove is not suitable for the fine polishing operation of the hand-held workpiece.
Disclosure of Invention
Based on the above, the present invention is to overcome the defects of the prior art, and provide a vibration damping tool for polishing a workpiece, which is a hand-transmitted vibration personal protection article specially used for other fine polishing operations such as fine polishing of a golf club head, and can effectively achieve the vibration damping effect, thereby protecting the fingers of an operator and not affecting the polishing efficiency of the operator.
The technical scheme is as follows:
a vibration reduction tool for grinding a workpiece for placement in an interior cavity of the workpiece, comprising: the packaging bag is deformable, and an accommodating cavity is arranged in the packaging bag; the damping particles are filled in the accommodating cavity; when the vibration reduction tool for polishing the workpiece is placed in the inner cavity, the damping particles can move under the thrust of the inner wall of the inner cavity, and the wrapping bag can automatically deform to adapt to the shape of the workpiece.
According to the vibration damping tool for polishing the workpiece, nonlinear damping exists in damping particles, and the vibration damping mechanism is that a damping effect is generated through inelastic collision and friction between particle materials and between the particle materials and the inner wall of the accommodating cavity, so that most vibration energy is consumed; meanwhile, the momentum exchange between the granular substances and the inner wall of the accommodating cavity can also play a role in inhibiting vibration, so that high-frequency vibration generated in the polishing process of the golf club head can be obviously absorbed and reduced. Meanwhile, as the whole vibration reduction tool is placed in the inner cavity of the workpiece, the weight of the workpiece can be increased during polishing, and according to Newton's second law: f=ma, the acceleration of the object is proportional to the resultant force F to which the object is subjected, inversely proportional to the mass of the object, and the direction of the acceleration is the same as the direction of the resultant force. Therefore, under the condition of unchanged resultant force, the vibration reduction bag is utilized to increase the mass of the workpiece to be polished, so that the vibration acceleration of the workpiece during polishing can be reduced, the hand-transmitted vibration acceleration contacted by a polishing worker is obviously reduced, the hand health of the polishing worker can be better protected, the workpiece is polished safely, and the phenomenon of polishing damage caused by vibration is not easy to occur. When the invention is used, the use of the traditional vibration reduction glove can be omitted, the fingers are in direct contact with the workpiece to operate, the flexibility of the fingers of workers is not affected, the grip strength during polishing is not increased, and the invention is particularly suitable for the fine polishing operation of golf heads. In addition, the whole vibration damping tool is arranged on the inner side of the workpiece, so that the vibration damping tool is not easy to damage. Finally, the wrapping bag disclosed by the invention is deformable, and the damping particles can also move freely, so that the shape of the inner cavity of the workpiece is adapted, the whole vibration damping tool is tightly attached to the inner wall of the workpiece, and the vibration damping effect is improved.
The technical scheme is further described below:
in one embodiment, the wrapping bag is made of elastic materials, and can be expanded and contracted to deform according to the size of the inner cavity of the actual workpiece, so that the wrapping bag is attached to the inner wall of the workpiece, and the vibration reduction effect is improved.
In one embodiment, the material of the wrapping bag is a material capable of resisting the high temperature of more than 300 ℃, so that the wrapping bag is prevented from being damaged in the high-temperature environment in the polishing process.
In one embodiment, the wrapping bag is made of meta-aramid fiber, has good elastic deformation capability and proper thickness, and has the characteristics of good durability, high reliability and insensitivity to temperature.
In one embodiment, the damping characteristics of the damping particles match the characteristic spectrum of the workpiece being polished. That is, according to the frequency of polishing, the material with corresponding damping coefficient is selected to meet the vibration reduction requirement and fully reduce the hand-transmitted vibration of the fine polishing operation of the workpiece.
In one embodiment, the damping particles include first damping particles and second damping particles, the first damping particles being an elastic material and the second damping particles being a rigid material, the first damping particles having a density less than a density of the second damping particles. According to the embodiment of the invention, the damping particles are composed of the elastic particles with lower density and the rigid particles with higher density, so that on one hand, the damping particles can be ensured to have certain elastic deformation capacity, and meanwhile, the damping particles can be ensured to have proper weight.

The natural rubber has moderate elastic deformation capability, and can promote the effect of being attached to the inner wall of the workpiece. Meanwhile, the silica particles have proper particle size, so that the silica particles cannot fall from the wrapping bag due to the fact that the particle size is too small, and the damping effect is poor due to the fact that the friction contact area is reduced due to the fact that the particle size is too large.

It should be understood that the detailed description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the invention.
It will be understood that when an element is referred to as being "fixed" to another element, it can be directly fixed to the other element or be fixed to the other element through intervening elements. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or be connected to the other element through intervening elements. Furthermore, unless specifically stated otherwise, the terms "first" and "second" and the like in the specification are used merely for distinguishing between various components, elements, steps, etc. in the specification and not for indicating a logical or sequential relationship between various components, elements, steps, etc.
As shown in fig. 1 and 2, the vibration damping tool for polishing a workpiece according to the embodiment of the invention is used for being placed in an inner cavity of the workpiece. The vibration reduction tool includes a wrap-bag 100 and a damping particle 200. Wherein the wrap-bag 100 is deformable, the package bag 100 is provided with an accommodating cavity 110; the damping particles 200 are filled in the accommodating cavity 110. When the vibration reduction tool is placed in the inner cavity of the workpiece, the damping particles 200 can move under the thrust of the inner wall of the inner cavity, the wrap-bag 100 may automatically deform to accommodate the shape of the workpiece.
The damping tool for polishing a workpiece according to the embodiment of the present invention has nonlinear damping in the damping particles 200, and the damping mechanism thereof is to generate damping effect through inelastic collision and friction between the particulate matters and the inner wall of the accommodating cavity 110, so as to consume most of vibration energy; meanwhile, the momentum exchange between the particulate matters and the inner wall of the accommodating cavity 110 can also play a role in inhibiting vibration, so that high-frequency vibration generated in the polishing process of the golf club head can be obviously absorbed and reduced. Meanwhile, as the whole vibration reduction tool is placed in the inner cavity of the workpiece, the weight of the workpiece can be increased during polishing, and according to Newton's second law: f=ma, the acceleration of the object is proportional to the resultant force F to which the object is subjected, inversely proportional to the mass of the object, and the direction of the acceleration is the same as the direction of the resultant force. Therefore, under the condition of unchanged resultant force, the vibration reduction bag is utilized to increase the mass of the workpiece to be polished, and the vibration acceleration of the workpiece during polishing can be reduced, so that the hand-transmitted vibration acceleration contacted by a polishing worker is obviously reduced, and the hand health of the polishing worker can be better protected. When the golf club head polishing device is used, the fingers are in direct contact with the workpiece to operate, the flexibility of the fingers of a worker is not affected, and the golf club head polishing device is particularly suitable for fine polishing operation of golf club heads. In addition, the wrapping bag 100 disclosed by the invention can be deformed, and the damping particles 200 can also freely move, so that the shape of the inner cavity of the workpiece is adapted, the whole vibration damping tool is tightly attached to the inner wall of the workpiece, and the vibration damping effect is improved.
In this embodiment, the material of the wrapping bag 100 is an elastic material, and the wrapping bag 100 can be expanded and contracted according to the size of the inner cavity of the actual workpiece, so as to be attached to the inner wall of the workpiece, thereby improving the vibration reduction effect. Further, the material of the wrapping bag 100 is a material that can withstand a high temperature of 300 ℃ or higher, so as to ensure that the wrapping bag 100 is not damaged in a high-temperature environment during polishing.
Optionally, the material of the wrapping bag 100 is meta-aramid, which has better elastic deformation capability and proper thickness, so that the wrapping bag 100 has the characteristics of good durability, high reliability and insensitivity to temperature. In other embodiments, the wrapping bag 100 may be made of other materials resistant to temperatures above 300 degrees celsius, such as para-aramid.
In this embodiment, the damping characteristics of the damping particles 200 match the characteristic spectrum of the workpiece being polished. That is, according to the frequency of polishing, the material with corresponding damping coefficient is selected to meet the vibration reduction requirement and fully reduce the hand-transmitted vibration of the fine polishing operation of the workpiece. Further, the damping particles 200 include first damping particles 200 and second damping particles 200, the first damping particles 200 are elastic materials, the second damping particles 200 are rigid materials, and the density of the first damping particles 200 is smaller than that of the second damping particles 200. According to the embodiment of the invention, the damping particles 200 are composed of the elastic particles with lower density and the rigid particles with higher density, so that on one hand, the damping particles 200 can be ensured to have certain elastic deformation capacity, and meanwhile, the damping particles 200 are ensured to have proper weight.
Alternatively, the first damping particles 200 are natural rubber particles, and the second damping particles 200 are silica particles. The natural rubber has moderate elastic deformation capability, and can promote the effect of being attached to the inner wall of the workpiece. Meanwhile, compared with conventional common damping particles such as sand (which is easy to fall out of the wrapping bag 100) or steel balls (which have larger particle sizes and smaller contact areas with each other and generate smaller friction), the silica particles in the embodiment of the invention have proper particle sizes, and cannot fall out of the wrapping bag 100 due to the fact that the particle sizes are too small, and cannot reduce the friction contact areas due to the fact that the particle sizes are too large, so that the damping effect is poor. It should be noted that, in other embodiments, the damping particles 200 may also be synthetic rubber particles, calcium carbonate particles, or the like.
In addition, the present invention further includes a pulling structure provided on the wrap-bag 100, which facilitates the operator to disassemble and assemble the vibration damping tool, thereby improving the polishing efficiency. Further, the lifting structure comprises a lifting ring 310, and the lifting ring 310 is convenient for an operator to lift and disassemble the vibration reduction tool. It should be noted that, in other embodiments, other types of lifting structures such as a handle may be used instead of the lifting ring 310.
The following simulation experiments were performed on the application of the vibration damping tool in the polishing operation of a golf club head:
1) The experimental method comprises the following steps: using a pneumatic polishing device, setting the rotating speed of the machine at 2200r/min, keeping constant 20N thrust, placing the golf club head, and a metal probe for measuring acceleration is fixed to the golf ball head.

2) Experimental conditions: blank golf club head and golf club head + vibration damping tool.
3) Experimental results: the average numbers of n groups of experimental data of the blank golf club head and the vibration damping tool are compared respectively, as shown in fig. 3, the average value of the vibration acceleration of the blank golf club head is 11.85m/s2, the average value of the vibration acceleration of the golf club head after the vibration damping tool is installed is 4.50m/s2, 62% is reduced, and the vibration damping effect is obvious.
In summary, the vibration damping tool for polishing a workpiece according to the present invention has the following advantages: the hand-transmitted vibration protection article is specially designed for the fine polishing operation of hollow metal workpieces such as hand-held golf heads, and the flexibility and the comfort of the hand-transmitted vibration protection article in use can meet the requirements of the fine polishing operation; the vibration-reducing device can effectively reduce high-frequency vibration above 400Hz, has a remarkable effect on low-frequency vibration below 400Hz, can inhibit resonance of a workpiece, reduces damage of hand-transmitted vibration to fingers of workers, and reduces occupational arm vibration diseases; the grip strength of a sander is not remarkably increased when the sander is used, the sander is not easy to fatigue and strain of skeletal muscles, and the sander has positive effects on improving the sanding efficiency of the sander; the wrapping material can bear the high temperature of 300 ℃ and ensure that the vibration reduction bag is not damaged in the high-temperature environment in the polishing process; the inner filling particles are composed of different high damping materials (silicon dioxide, natural rubber and the like), and the materials can absorb vibration generated in the polishing process of the workpiece; the lifting structure is provided, so that an operator can conveniently take and load the lifting structure.
