Abstract
The invention relates to a mounting structure of a nail gun fan motor, belonging to the technical field of gas power tools. The structure comprises a fan motor positioned in a mounting hole in the middle of a combustion chamber cover, wherein two ends of the motor are respectively mounted in the mounting hole through an upper buffering and damping structure and a lower buffering and damping structure, and at least one of the buffering and damping structures is composed of two repellent magnetic parts respectively fixed at the end part of the motor and in the mounting hole. When the other end of the motor adopts the cushion similar to the prior art for buffering and damping, the cushion and the magnetic part have completely different buffering and damping characteristics, so that the vibration caused by impact force can be effectively inhibited, the stable and reliable work of the fan motor can be ensured, and the service life of the fan motor can be prolonged. If the two ends of the motor adopt mutually exclusive magnetic piece buffering and damping structures, the magnetic pieces can easily have different buffering and damping characteristics by selecting different materials and different magnetizing means, so that the effect can be achieved.
Description
Technical field
The present invention relates to a kind of internal structure of gas power impact tool, especially a kind of nailing gun fan electromotor installation
Structure, belong to gas power technical field of tools.
Background technology
Nailing gun completes the impact of the fasteners such as nail using combustion gas as power, by the drivig cylinder of combustion chamber, and it burns
Chamber cap is respectively arranged with motor-driven fan, to ensure the abundant burning of combustion gas and cool down cylinder body.In order to avoid nailing gunslinging
The influence to motor is played, the fan electromotor installation of existing nailing gun takes necessary bumper and absorbing shock measure, its typical structure
As shown in figure 1, the lower end of motor 4 of fan 1 is directly installed by lower rubber cushion 3, upper end through bushing 5 indirectly by upper rubber cushion 6
In the mounting hole at the middle part of combustion chamber lid 2, and have respectively by packing ring 7 and the axial limiting of jump ring 8, lower rubber cushion 3 and upper rubber cushion 6
The bulge loop of embedded mounting hole, it is achieved thereby that Grazing condition connects, can effective bumper and absorbing shock, be advantageous to the reliably working of fan.
However, this existing buffer damping structure assembling is not convenient enough, and due to the elasticity of motor both ends padded coaming
Coefficient is basically identical, therefore after absorption nailing impulsive force, motor is produced the vibration of long period, is unfavorable for keeping electricity
The smooth working of machine.
The content of the invention
It is an object of the invention to：For in place of above-mentioned the shortcomings of the prior art, being improved by structure, propose a kind of
Not only can effectively bumper and absorbing shock and can suppress vibration nailing gun fan electromotor installation structure.
In order to reach object above, the basic technical scheme of nailing gun fan electromotor installation structure of the present invention is：Including position
In the fan electromotor in the middle part of combustion chamber lid in mounting hole, the both ends of the motor are installed by upper and lower buffer damping structure respectively
In the mounting hole, one of at least described buffer damping structure is repelled each other by be separately fixed in motor end and mounting hole two
Magnetic part is formed.
When the motor other end uses the rubber cushion bumper and absorbing shock similar with prior art, because rubber cushion and magnetic part have had
Complete different bumper and absorbing shock characteristic, therefore can effectively suppress to vibrate caused by impulsive force, it is more beneficial for ensureing that fan electromotor is put down
Steady reliably working, and its service life can be extended.When using mutual exclusion magnetic part buffer damping structure such as motor both ends, due to magnetic
Property part be easy to make it have dramatically different bumper and absorbing shock characteristic by selecting unlike material and the different means of magnetizing, therefore
The effect above can be reached.
In a word, the present invention realizes that compression resets using the principle that identical charges repel each other, so as to play cushioning effect, is hanged with magnetic
The reliable and stable remarkable advantage of damping is hung, therefore electrical machinery life can be extended, product quality is got a promotion, and assembles and safeguards ten
It is convenient to divide.
Further embody of the invention includes：
The motor lower end is connected magnet ring, and magnetic cushion shock-damping structure is formed with the magnetic part being fixed in mounting hole.
The motor upper end is connected magnet ring, and magnetic cushion shock-damping structure is formed with the magnet assembly being fixed in mounting hole.
Magnet ring is respectively fixedly connected in the motor both ends, and two magnet rings form with the relative magnetism component being fixed in mounting hole respectively
Magnetic cushion shock-damping structure.
The magnet assembly is made up of magnetic pole fixed seat and magnetic pole, and the magnetic pole fixed seat is formed with circumferential uniform counterbore,
Fixed magnetic pole is respectively embedded into each counterbore.
The central diameter of the pitch circle diameter of the magnetic pole and the magnet ring matches.
Brief description of the drawings
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the fan electromotor installation structure schematic perspective view of prior art.
Fig. 2 is the dimensional structure diagram of the embodiment of the present invention one.
Fig. 3 is the assembly structure diagram of the embodiment of the present invention one.
Fig. 4 is the structural representation of the embodiment of the present invention two.
Embodiment
Embodiment one
The nailing gun fan electromotor installation structure of the present embodiment as shown in Figures 2 and 3, is installed in the middle part mounting hole of combustion chamber lid 2
The fan electromotor 4 of driving fan 1, the upper end and prior art in the shown position of motor 4 are essentially identical, through being connected between bushing 5
Rubber cushion 6 is crossed in the mounting hole at the middle part of combustion chamber lid 2, and by packing ring 7 and the axial limiting of jump ring 8, lower end is connected magnetic
Ring 11, with being fixed on that mounting hole is relative built with the magnetic pole fixed seat 12 of magnetic pole 13, composition two repels each other the magnetic of magnetic part composition
Buffer damping structure.Magnetic pole fixed seat 12 is formed with four uniform counterbores of circumference, is respectively embedded into fixed magnetic pole 13, point of magnetic pole 13
The central diameter of cloth circular diameter and magnet ring 11 matches, therefore can form the cushion effect that preferably axially repels each other.
Experiment proves that the motor both ends of the present embodiment have entirely different bumper and absorbing shock special due to rubber cushion and magnetic part
Property, therefore can effectively suppress to vibrate caused by impulsive force, the steady reliably working of fan electromotor is kept, service life obtains substantially
Extend.
Embodiment two
As shown in figure 4, basic structure is identical with embodiment, difference exists the nailing gun fan electromotor installation structure of the present embodiment
In the position that two kinds of buffer damping structures being made up of respectively rubber cushion and magnetic part are just exchanged, due to motor both ends rubber cushion with
Magnetic part equally has different bumper and absorbing shock characteristics, therefore its action effect and embodiment one are essentially identical.
Embodiment three
The nailing gun fan electromotor installation structure feature of the present embodiment is that motor both ends use magnetic cushion shock-damping structure, simply
The magnetic field intensity of both ends magnetic part because selection unlike material and it is different, therefore can also reach be substantially the same as in the previous example delay
Rush effect.
