Automatic disconnecting device for tool gas source

Abstract

The invention provides an automatic disconnecting device for a tool gas source. The automatic disconnecting device comprises a base, a support, a gun stock base, a lever mechanism, a balancing weight and a stop valve. The lever mechanism is hinged to the top of the support, the gun stock base is fixed to one end of the lever mechanism, and the balancing weight is fixed to the other end of the lever mechanism. The stop valve is linked with the lever mechanism and is used for controlling the on-off of an air source; when the pneumatic tool is placed on the gun stock base, the weight of the pneumatic tool drives the balancing weight to ascend through the lever mechanism, and the balancing weight drives the stop valve to be closed. And when the pneumatic tool is taken down from the gun stock base, the balancing weight falls down, the stop valve restores the opening state, and the air source is communicated.

Description

Technical Field

[0001] This application relates to the field of pneumatic system control technology, and more specifically, to a tool air source automatic disconnection device. Background Technology

[0002] In industrial production settings such as automobile assembly workshops, pneumatic tools such as pneumatic riveting guns and pneumatic wrenches are widely used in riveting and bolting operations. These tools are typically connected to the factory's compressed air system via hoses. Due to the inherent structural characteristics of these tools, they may continue to vent air even when not in use, resulting in a waste of compressed air. Currently, most solutions to this problem rely on manual operation to close ball valves or disconnect connectors, or on building automated control systems using sensors and solenoid valves. However, the former is highly dependent on manual operation and cumbersome, and cannot be effectively shut off at all times under tight production schedules, resulting in significant compressed air losses. The latter has a complex structure, a high failure rate, and high cost.

[0003] Therefore, there is an urgent need for a mechanical device that requires no power supply or manual intervention, can automatically determine the status of tools and control the air supply, in order to improve production efficiency and reduce energy consumption. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide an automatic gas supply disconnection device for tools, which uses a lever principle to activate a shut-off valve to supply and cut off the gas supply, and uses the counterweight of the gun stock to control the automatic opening and closing of the gas valve.

[0005] The automatic gas supply disconnection device provided in this application includes a base, a bracket, a buttstock base, a lever mechanism, a counterweight, and a shut-off valve; the lever mechanism is hinged to the top of the bracket, the buttstock base is fixed to one end of the lever mechanism, and the counterweight is fixed to the other end of the lever mechanism; the shut-off valve is linked to the lever mechanism and is used to control the on / off of the gas supply.

[0006] in:

[0007] When the pneumatic tool is placed on the stock base, the weight of the pneumatic tool drives the counterweight to rise through the lever mechanism, and the counterweight drives the shut-off valve to close.

[0008] When the pneumatic tool is removed from the stock base, the counterweight falls, the shut-off valve returns to the open state, and the air supply is connected.

[0009] Preferably, the rotation angle of the lever mechanism is 45°.

[0010] Preferably, the counterweight includes a plurality of counterweight plates, and the weight of the counterweight can be adjusted by increasing or decreasing the number of counterweight plates.

[0012] Preferably, the lever mechanism includes an input end and an output end, the input end is fixedly connected to the stock base, and the output end is fixedly connected to the counterweight; the lever arm ratio of the input end and the output end is 1:4, 1:5, or 1:6.

[0013] Preferably, the shut-off valve is provided with an air passage interface, which is a stepped variable diameter structure that can be compatible with air source connectors with a pipe diameter of 1 / 4'' or 3 / 8''.

[0014] Compared with the prior art, this application has the following beneficial effects:

[0015] 1. The automatic gas supply disconnection device provided in this application utilizes the lever principle and a lever-counterweight mechanical linkage mechanism to adaptively sense and control the gas supply on / off, without requiring a power source or complex system.
