Between plate, the limit plate is fixed by screws in upper end face of support plate left and right edges position, and the cavity two is provided with limit
Intralamellar part, the expansion plate are arranged on cavity two, and the cavity one is provided in support stick, and cavity one is arranged in cavity
Immediately below two, and it is logical to be connected with each other, and the cavity one is internally provided with piston block, passes through bearing and screw thread on the outside of the piston block
Bar is connected, and threaded rod is in contact by screw thread with support stick, and threaded rod outer end is each passed through support stick or so two
End, the miniature sucker are embedded in support stick lower end surface, and the push plate is separately positioned on support plate rear and front end, the cavity
Three are provided with inside support stick, and the convex block is separately positioned on three rear and front end of cavity, and convex block outer end passes through cavity three, and
It is in contact with push plate.
6. a kind of fine-tuning shock-absorption device of brshless DC motor according to claim 5, it is characterised in that：The cage plate
Inside offers stepped groove, and motor body is set on stepped groove, and the expansion plate is in contact by O-ring with cavity two,
And expansion plate upper end is pasted with rubber pad, in actual use, user of service rotates threaded rod, and then threaded rod rotates and in spiral shell
It is moved inward under the action of line, threaded rod, which moves inward, drives piston block to move inward, and piston block moves inward to cavity
Air in one is squeezed, and then the air in cavity one is caused to enter inside cavity two, and then drives expansion plate to moving up
Dynamic, when expansion plate is moved upwards up to specified altitude assignment, stop operating threaded rod, and then user of service rotates trimming bolt, fine tuning
Bolt is rotated and is moved down along internal thread hole, while trimming bolt moves down and cage plate is driven to move down, and cage plate is downward
Movement can compress damping spring, while cage plate moves down can shorten the distance between expansion plate, downward in cage plate
When being moved to proper height, stop operating trimming bolt, and when motor body is by the power moved down, motor body is to moving down
It moves and cage plate is driven to move down by bearing along trimming bolt, cage plate, which moves down, to carry out secondary pressure to damping spring
Contracting, then damping spring bounce effect under hinder cage plate move down, while cage plate move down can drive expansion plate to
Lower movement, then expansion plate, which moves down, to pressurize to the space inside cavity two, and then cavity two is restoring draught head
Under the action of hinder expansion plate to move down, and then cage plate and motor body are hindered, realize the function of secondary shock-absorbing
Can, while the intensity of damping can also be finely adjusted.
7. a kind of fine-tuning shock-absorption device of brshless DC motor according to claim 5, it is characterised in that：It is described miniature
Sucker is equipped at least two, and at least two miniature suckers are uniformly embedded in support stick lower end, the support plate front and back two
End is machined with sliding groove, and push plate is provided on sliding groove, and the support plate rear and front end left and right edges position is provided with
Block, and block passes through shaft and is connected with support plate, hemispherical outside the convex block, the support stick upper end is pasted
There is sealing ring, and sealing ring is arranged between cavity one and cavity two, in actual use, user of service passes through miniature sucker
Support stick is fixed, then user of service moves down support plate, and support plate moves down to be in contact with convex block,
Then support plate moves down and passes through the hemispherical of convex block and squeezes convex block, to realize that convex block enters in cavity three
Portion, and then to pressurizeing inside cavity three, then support plate continues to move down to wrap support stick, so
Convex block is displaced outwardly under the action of cavity three restores air pressure afterwards, to realize that convex block hemispherical position enters the cunning in support plate
It in dynamic slot, and then realizes and support plate is fixed, when being dismantled, user of service inwardly moves along sliding groove
Dynamic push plate, and then convex block is driven to move inward, to realize that convex block is mutually separated with support plate, then user of service is in shaft
Axis carries out rotary block, and then realizes and hinder push plate, and then user of service moves up support plate, to realize branch
Fagging is mutually separated with support stick, and the function of sealing can be achieved in the design of sealing ring, realizes the function of fast assembling-disassembling, while
It reduces and occupied area is installed.
