Problems solved by technology

However, due to the small volume of the small tank itself, the power adjustable range is small
In addition, this adjustment action is not precisely controlled by the control system, making the power adjustment inaccurate
[0010] 4. The nail fixer still does not solve the problem of accurate automatic compensation after the gas micro-leakage in the cylinder
When the pressure in the cylinder is high, it is difficult for the crank rocker to store energy
However, only one steel ball in the unilateral blocking structure will be difficult to achieve the limit of the firing pin, and the limiting ability of the unilateral blocking structure to the firing pin depends on the spring performance, the shape of the steel ball and the coefficient of friction. During use, these The parameters will change, which will also make the limit ability of the unilateral blocking structure unstable, and then the nailing effect will be unstable.

Abstract

The invention discloses a double-air-cylinder electric nail fixing device which comprises a main air cylinder, an auxiliary air cylinder, a linear motion mechanism, a firing pin, a needle tube assembly, a driving mechanism and a limiting releasing mechanism. The main air cylinder is fixedly connected with the auxiliary air cylinder, and an inner cavity of the main air cylinder is communicated with an inner cavity of the auxiliary air cylinder; a main piston and an auxiliary piston are arranged in the main air cylinder and the auxiliary air cylinder respectively, the needle tube assembly is fixedly connected with the main air cylinder through a connecting piece, one end of the firing pin is movably arranged in the needle tube assembly, and the other end of the firing pin is fixedly connected with the main piston. The limiting and releasing mechanism used for limiting or releasing the firing pin is arranged beside the firing pin, the linear motion mechanism is fixedly connected with the auxiliary piston, and the driving mechanism is connected with the firing pin and the linear motion mechanism. Compression of high-pressure gas in the cylinder can be achieved under the condition that the bearing capacity is small, and the micro leakage amount of the gas in the cylinder can be automatically compensated and the nailing power can be automatically adjusted by adjusting the stroke of the driving mechanism.

Description

technical field [0001] The invention belongs to the technical field of fastening, and in particular relates to a double-cylinder electric nail fixer. Background technique [0002] Existing electric nail fixers are mainly divided into single-cylinder and double-cylinder structures. For the single-cylinder nail fixer, it mainly realizes the nail-fixing action by presetting high-pressure gas with different energy in the cylinder, but the single-cylinder nail fixer has the following technical problems in practical application: [0003] First, the single-cylinder nail fixer adopts gear transmission for high-pressure gas compression, and the transmission system has a large load and is prone to failure, so that the single-cylinder nail fixer has not been able to break through the bottleneck of high-power nail fixation. Second, the parameters of the single-cylinder nail fixer are fixed, and it does not have the function of adjusting the power of nailing. Third, the single-cylinder...
