Problems solved by technology

However, gas nail guns use gas explosions to operate, and the rapid mixing and ventilation of the gas in the cavity requires a fan motor with continuous fatigue resistance and long-term explosion resistance, which is currently an insurmountable technical problem.
Since the fan blade of the gas nail gun motor must be placed in the gas explosion cavity of the gas nail gun, the axial direction of the motor will be subjected to a huge impact force when the gas explodes, and the ordinary motor structure cannot withstand the fatigue of the impact force caused by the gas explosion Condition

Embodiment Construction

[0032] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0033] refer to Figure 1 to Figure 4 The anti-axial impact motor of this embodiment includes: motor shaft 1, retaining ring 2, first bearing 3, motor magnet seat 4, compression spring 5, magnet 15, second bearing 14, coil disc 8, coil 7, Commutator 16, carbon brush 9, carbon brush fixed shaft 13, torsion spring 12, brush stand 10, rear cover 11, motor housing 6.

[0034] Wherein, the motor magnet seat 4 is disposed inside the motor housing 6 , and the motor magnet seat 4 has an inner hole through which the motor shaft 1 passes. A retaining ring 2 is fixed on the part of the motor shaft 1 protruding from the motor housing 6. When the motor shaft 1 is subjected to an axial impact, the retaining ring 2 moves with the motor shaft until it touches the motor magnet seat 4....

Abstract

The invention provides a motor resisting axial impact and a gas nailer including the same. The axial impact resisting motor comprises a motor shell, a motor magnet seat arranged in the motor shell, and a motor shaft penetrating the internal hole of the motor magnet seat; the part of the motor shaft extending out of the motor shell is fixed with a retaining ring; when the motor shaft suffers from axial impact, the retaining ring moves along with the motor shaft to be in contact with the motor magnet seat. The motor and gas nailer provided by the invention can bear the axial impact and protect the internal part of the motor from being damaged by gas explosion impact; and moreover, the displacement problem when the coil plate and the motor shaft, the coil and the coil plate are axially impacted at the motor shaft can be solved; and the rotation of the motor and the gas nailer can be fast recovered after being impacted so as to realize normal use.

Description

technical field [0001] The invention relates to an axial impact resistance motor and a gas nail gun comprising the axial impact resistance motor. Background technique [0002] Wood fixing work in the modern construction industry usually uses a pneumatic nail gun, which shoots iron nails through the pressure of compressed gas to fix the wood. It is restricted, and it is easy to cause danger when pulling the air pipe when working at heights. [0003] For the above reasons, there is a strong demand on the market for a nail gun without an air tube to replace the pneumatic nail gun. The gas nail gun uses the pressure of the gas explosion to shoot iron nails to fix the wood, so it has become a new product that replaces the pneumatic nail gun. However, gas nail guns use gas explosions to operate, and the rapid mixing and ventilation of the gas in the cavity requires a fan motor with continuous fatigue resistance and long-term explosion impact resistance, which is currently an ins...
