Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas nail gun technology, and in particular to a motor fixing component for a gas nail gun. Background Technology
[0002] As the core power component of a gas nail gun, the electric motor's operating status plays a decisive role in the gun's performance and nailing quality. During operation, the motor needs to run at high speed to provide sufficient power, but this high speed inevitably generates strong vibrations. However, traditional gas nail gun motor fixing methods have significant shortcomings in dealing with such vibrations. On the one hand, some traditional fixing methods are not sufficiently secure in the axial fixation of the motor assembly, easily leading to unstable connections between the motor shaft and the fan blade support, affecting the stable rotation of the fan blades, and thus reducing operational reliability and nailing accuracy. On the other hand, traditional gas nail guns lack a real-time monitoring mechanism for the motor's operating status, making it difficult for operators to detect motor faults in a timely manner, potentially allowing the fault to escalate and affecting normal equipment use. Furthermore, the internal environment of a gas nail gun is complex during use; external dust, moisture, metal debris, and other impurities can easily penetrate the combustion chamber cover. Simultaneously, the high-temperature, high-pressure gas inside the combustion chamber poses a risk of leakage, not only wasting energy but also potentially threatening the safe operation of the equipment. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide a gas nail gun motor fixing component that is simple in structure, reliable in operation, and can monitor the motor status in real time.
[0004] To achieve the above objectives, this utility model employs a motor fixing assembly for a gas nail gun, including a combustion chamber cover. The combustion chamber cover has an installation groove, and a motor assembly is installed within the installation groove. The motor assembly includes a motor, with a sealing cover installed at one end and a bearing installed at the other end. A wave spring is provided on the sealing cover, and a gasket is provided at the end of the wave spring away from the sealing cover. One end of the wave spring is engaged with the sealing cover, and the other end is engaged with the gasket. A retaining ring is provided on the gasket, and the retaining ring is installed on the top of the installation groove and covers the gasket. A fan assembly is provided at the end of the bearing away from the motor. The fan assembly includes a support member and fan blades installed around the support member. The motor has a motor shaft at the end corresponding to the bearing, and the bearing has a slot corresponding to the motor shaft. The motor shaft passes through the slot and is inserted into the support member of the fan assembly. An encoder module is installed on one side of the combustion chamber cover within the installation groove.
[0005] The beneficial effects of the above structure are as follows: By installing the snap ring on top of the mounting slot and covering the gasket, and by designing the wave spring with the sealing cap and gasket respectively at both ends, a stable axial fixation can be provided for the motor assembly. During the operation of the gas nail gun, the high-speed operation of the motor will generate vibration. This fixing method can effectively reduce the axial movement of the motor assembly, ensure the connection stability between the motor shaft and the fan blade assembly support, and enable the fan blade to rotate continuously and stably, thereby improving the working reliability of the gas nail gun. In addition, the encoder module can monitor the motor speed, position and other key information in real time. The operator can understand the motor's operating status in a timely manner based on the information fed back by the encoder module, so as to take corresponding measures in case of abnormality, avoid the gas nail gun from malfunctioning due to motor failure, and further ensure the normal use of the gas nail gun and the nailing quality.
[0006] This utility model is further configured such that a groove is provided on the outer wall of the combustion chamber cover, and a sealing ring is embedded in the groove. The sealing ring provides a double barrier function, preventing external dust, moisture, metal debris, and other impurities from entering the combustion chamber cover, and also preventing leakage of the high-temperature and high-pressure gas generated in the combustion chamber when the gas nail gun is working, thus ensuring safe operation of the equipment and reducing energy waste.
[0007] This utility model is further configured with an insertion hole on the combustion chamber cover, and a pin is provided in the insertion hole. With the pin, when assembling the gas nail gun, the pin can be inserted into the insertion hole to initially fix the position of the combustion chamber cover. During disassembly and maintenance, pulling out the pin allows for quick separation of the combustion chamber cover from other components, facilitating internal inspection and repair.
