Caulking gun

Abstract

The invention discloses a caulking gun. The caulking gun comprises a gun body, a caulking rod and a transmission mechanism. Rolling wheels for driving the gun body to move are arranged at the bottom side of the gun body. The caulking gun is arranged in the gun body and used for driving a caulking disc in the gun body to move to achieve caulking. The transmission mechanism is used for converting rotation of the rolling wheels into linear movement of the caulking rod, the input end of the transmission mechanism is connected with the rolling wheels, the output end of the transmission mechanism isconnected with the caulking rod, and the transmission mechanism has a preset transmission ratio. The caulking amount of the caulking gun is controlled through transmission of a pure mechanical structure, uniform caulking is achieved, the situation that the gluing amount is not uniform due to the volatility of manual operation is avoided, compared with an electric or pneumatic caulking gun in theprior art, a detection and feedback system and a control system are omitted in the caulking gun, and the caulking gun is simple in structure, stable and reliable in transmission, low in cost, free ofbeing limited by a power source or a gas source and flexible and convenient to use, and has very high practical value and practical significance for a gluing process.

Description

technical field [0001] The present invention relates to the technical field of gluing devices, and more particularly, to a gluing gun. Background technique [0002] In the technical fields of equipment manufacturing such as ships, wind power, building materials, metallurgy, and automobiles, it is usually necessary to fasten and assemble the components of the split design by combining the cooperation between the planes, for example, the split box of the gearbox. The assembly between the boxes, the assembly between the box shaft end covers, etc. [0003] When two split parts are assembled face-to-face, there is often a gap between the joint surfaces due to manufacturing errors and / or uneven tightening force. Apply flat glue between them to eliminate the gap at the joint surface. In order to achieve better sealing, the amount of glue applied is required to be uniform and continuous. If the glue quantity is not properly controlled, the gap between the joint surfaces may not b...

Problems solved by technology

This glue pressing method reduces the labor intensity of manually pressing the trigger. However, it is necessary to ensure the uniformity of the glue application when the glue gun moves at a constant speed. The detection system used to measure the moving speed of the gun body, through the feedback of the detection system, real-time control of the motor speed to adjust the glue pressure, covers the fields of machinery, electricity and control, the technology is complicated, the price is high, and it involves power supply and air pressure source etc., the flexibility of using the glue gun is poor
