Abstract

The utility model relates to a motor suspension mechanism for a gas nailer. The motor is arranged on a back cover of a combustion chamber of a gas nailer body. The motor suspension mechanism is characterized in that a fixing ring is sleeved on the motor, and fixing blocks are respectively pressed at the two sides of the fixing ring in the axial direction of the motor; a damping spring is arranged at the outer side of each fixing block, and at least two fixing screws penetrate through the fixing blocks arranged on the motor and the damping springs to fix the motor clamped by the fixing ring in a chamber of the back cover of the combustion chamber. The damping springs are arranged at the outer sides of the fixing blocks for clamping the fixing ring, so that the damping springs have a cushion effect on the motor in internal explosion to protect the motor against damage and prolong the service life of the motor.

Description

Gas nail gun motor suspension mechanism

Technical field

The utility model relates to a kind of motor suspension mechanism, is specifically related to a kind of gas nail gun motor suspension mechanism, belongs to the pneumatic tool technical field.

Background technology

Gas nail gun is when internal explosion, fan can be subject to powerful impulsive force laterally, blade on the fan produces thrust to the rotor of motor, so that to some extent displacement of rotor and stator, if it is firm that fan is fixed, have so and just may cause motor dislocation, can exert an influence and even lifetime to the use of gas nail gun.

Summary of the invention

The purpose of this utility model is exactly the problem that is installed in the unreasonable structure on the gas nail gun for motor.

The technical scheme that the utility model will be dealt with problems is as follows:

Gas nail gun motor suspension mechanism, comprise motor, motor is installed on the combustion chamber bonnet of nail gun rifle body, it is characterized in that: cover has retainer plate on the described motor, motor axially on the both sides of retainer plate be pressed with respectively fixed block, the outside at fixed block is provided with shock-absorbing spring, and plural at least hold-down screw passes the motor that the fixed block that is installed on the motor and shock-absorbing spring the retainer plate clamping and is fixed in the chamber of combustion chamber bonnet.

Also be provided with pad between the outside of described fixed block and the combustion chamber bonnet.

The axle head of described motor passes flabellum seat and flabellum successively, passes pedestal at side one holding screw of flabellum seat and is against on the motor shaft.

The port of the described flabellum seat outside is placed with buckle with the structure matching of flabellum inboard along port, and the flabellum seat is fixed in flabellum on the pedestal by buckle.

The beneficial effects of the utility model are as follows:

Compared with prior art; adopt the gas nail gun motor suspension mechanism of the utility model structure, adopt gripping the fixed block outside dress shock-absorbing spring of circle, when being subject to internal explosion, can carry out cushioning effect to motor; the protection motor is not damaged, and prolongs motor service life.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is done further detailed elaboration.

Consult Fig. 1 to Fig. 4.

Embodiment one, gas nail gun motor suspension mechanism, comprise motor (1), motor (1) is installed on the combustion chamber bonnet (3) of nail gun rifle body (2), the upper cover of described motor (1) has retainer plate (4), the axial upward both sides of retainer plate (4) at motor (1) are pressed with respectively fixed block (5), be provided with shock-absorbing spring (6) in the outside of fixed block (5), plural at least hold-down screw (7) passes the motor (1) that the fixed block (5) that is installed on the motor (1) and shock-absorbing spring (6) retainer plate (4) clamping and is fixed in the chamber of combustion chamber bonnet (3).

Producing powerful impulsive force after the combustion chambers burn blast goes out motor (1) laterally, because of motor (1) circle (4) that is fixed clamping, and retainer plate (4) is headed on by the fixed block of both sides (5), fixed block (5) outside is placed with again shock-absorbing spring (6), for this reason, compression after the impulsive force of shock-absorbing spring (6) in the combustion chamber produces, the elastic reset of shock-absorbing spring (6) had so just played a good cushioning effect so that motor (1) is got back to original position when the elastic force of shock-absorbing spring (6) and impulsive force maintained an equal level by the time.

In like manner; namely the outside of fixed block (5) also is provided with a shock-absorbing spring (6) between the outside of fixed block (5) and combustion chamber bonnet (3); like this when impact force action motor (1); shock-absorbing spring (6) move left and right rubbing motor (1) is comprehensively protected is so that the ILS of motor (1).

Embodiment two based on embodiment one, also is provided with pad (figure is mark not) between the outside of described fixed block (5) and the combustion chamber bonnet (3).

Embodiment three, based on embodiment one, the motor shaft end of described motor (1) is passed flabellum seat (8) and flabellum (9) successively, passes pedestal at side one holding screw (10) of flabellum seat (8) and is against on the motor shaft.

Consult Fig. 5, embodiment four, based on embodiment three, the port of described flabellum seat (8) outside is placed with buckle (81) with the inboard structure matching of flabellum (8) along port, and flabellum seat (8) is fixed in flabellum (8) on the pedestal by buckle (81).

The combustion chamber bonnet (3) that motor (1) is installed on nail gun rifle body (2) afterwards, A is that motor shock-absorbing spring (6) is impacted the direction of motion afterwards by impulsive force after the combustion chambers burn blast, B then is the direction of motion of motor fixed block (5), and C is the direction of motion of flabellum (8) and motor (1).

Claims

1. gas nail gun motor suspension mechanism, comprise motor, motor is installed on the combustion chamber bonnet of nail gun rifle body, it is characterized in that: cover has retainer plate on the described motor, motor axially on the both sides of retainer plate be pressed with respectively fixed block, the outside at fixed block is provided with shock-absorbing spring, and plural at least hold-down screw passes the motor that the fixed block that is installed on the motor and shock-absorbing spring the retainer plate clamping and is fixed in the chamber of combustion chamber bonnet.
