Description

Technical Field

[0001] This utility model relates to the technical field of air pipe fitting equipment, and in particular to a semi-automatic air pipe quick fitting tool. Background Technology

[0002] In the process of pressing air tube connectors, fully automated pressing equipment has a complex structure, is difficult to maintain, and greatly increases equipment costs. Therefore, most factories use manual pre-assembly followed by semi-automatic equipment for pressing. However, traditional semi-automatic pressing equipment has poor air tube fixing effect and is prone to slippage during pressing, resulting in unreliable pressing. At the same time, inaccurate control of cylinder action sequence can also lead to loose connection problems in air tube pressing, resulting in air leakage when the air tube is connected to the device, causing defects in the products produced by the equipment. Therefore, this utility model proposes a semi-automatic rapid air tube pressing tool to solve the problems existing in the prior art. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to propose a semi-automatic rapid air hose pressing fixture. This fixture, through a time relay-controlled solenoid valve regulating cylinder coordination mechanism, combined with the coordinated tightening of lever cylinder and pressing block, can press the air hose tightly during air hose fitting, preventing air hose slippage. This solves the problem of loose pressing in traditional devices. The device has a simple structure, good pressing effect, simple operation, and significantly reduced maintenance costs.

[0004] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: a semi-automatic rapid air tube pressing fixture, including a pressing table, a fixing mechanism, a positioning seat, a pressing cylinder, a pressing head, and a control mechanism. The fixing mechanism is provided on one side of the pressing table, and the pressing cylinder is provided in the middle of the pressing table via the positioning seat. The pressing head is provided at the telescopic end of the pressing cylinder. The pressing head is pushed to the right by the pressing cylinder to compress the end of the air tube, making it tightly connected to the fixed air tube. A control mechanism is provided on the pressing table. The fixing mechanism includes a fixing seat, a positioning groove, a lever cylinder, a hinged pressure bar, a biting rack, and a pressing mechanism. A fixing seat is provided on one side of the pressing table, and a positioning groove is provided on the fixing seat for fitting and fixing the pressing air tube. A hinged pressure bar is provided on the rear side of the fixing seat through a lever cylinder. A biting rack is provided below the hinged pressure bar corresponding to the position of the positioning groove. The lever cylinder drives the hinged pressure bar to press downward, so that the biting rack bites the air tube to prevent slippage. A pressing mechanism is provided on the front side of the fixing seat.

[0005] A further improvement is that the clamping mechanism includes a two-way cylinder, a connecting plate, a clamping block, and a ramp section. The two-way cylinder is fixedly installed on the front side of the fixed base. The connecting plate is symmetrically arranged on the telescopic end of the two-way cylinder. The clamping block is arranged on the upper end of the connecting plate. The ramp section is symmetrically arranged on the front end of the hinged pressure strip for further tightening the hinged pressure strip.

[0006] Further improvements include: symmetrical guide slide rods are provided on opposite sides of the connecting plate between the two-way cylinder, and the lower side of the clamping block is also a sloping structure that is adapted to slide on the sloping section, further pressing the press-fitted air pipe.

[0007] A further improvement is that the control mechanism includes a first solenoid valve, a second solenoid valve, a third solenoid valve, a time relay, a regulating controller, a pressure regulating valve, and a main switch. The first solenoid valve, the second solenoid valve, and the third solenoid valve are arranged below the pressing platform. A time relay is arranged on the other side above the pressing platform. A regulating controller is arranged on one side of the time relay. A pressure regulating valve is arranged on the front side of the pressing platform. A main switch is arranged above the pressing platform.

[0008] Further improvements include: the first solenoid valve is connected to the lever cylinder pipeline, the second solenoid valve is connected to the bidirectional cylinder pipeline in the clamping mechanism, and the third solenoid valve is connected to the press-fit cylinder pipeline, each used to control the operation of different cylinders. The first, second, and third solenoid valves are all connected to an external air source through a pressure regulating valve, which controls the air pressure. The time relays are provided in three sets, each electrically connected to the first, second, and third solenoid valves. The time relays control the operation of different solenoid valves to achieve coordinated operation of the cylinders. The three sets of time relays are electrically connected to a regulating controller, which sets the reaction time of the time relays. The regulating controller is electrically connected to an external power source through a main switch.

[0009] Further improvements include: a hard rubber block is provided at the front end of the pressing head to prevent the metal pressing head from damaging the air pipe connector; the pressing head is coaxially arranged with the positioning groove; the hinged pressing strip is rotatably hinged to the lever cylinder through a hinged plate; and the tail end of the hinged pressing strip is hinged to the telescopic end of the lever cylinder.

[0010] The beneficial effects of this utility model are as follows: By setting a time relay to control the solenoid valve and adjust the cylinder coordination mechanism, and coordinating the lever cylinder and the clamping block for fastening, this utility model can press the air pipe tightly during the press-fitting of the air pipe joint, avoiding the phenomenon of air pipe slippage. This solves the problem of loose press-fitting in traditional devices. The device has a simple structure, good press-fitting effect, simple operation, and greatly reduced maintenance costs.
