Description

Actuating mechanism of automatic oil dispenser

technical field

The utility model relates to an automatic fuel dispenser, in particular to an executive mechanism of the automatic fuel dispenser for fueling the engine.

Background technique

The engine of a motor vehicle will be injected with a certain amount of fuel before assembly at the factory to facilitate debugging. At present, the fuel filling of the engine is mostly completed by manual operation, that is, when the engine is put in place through the assembly line, the operator holds the oil gun and adds the engine oil to the engine. In this filling method, one or two operators need to be fixed , so its production cost is high.

Contents of the invention

The purpose of the utility model is to provide an executive mechanism of an automatic fuel dispenser, which is beneficial to save production cost and has the advantages of convenient operation.

The purpose of this utility model is achieved like this:

The cylinder body of the first cylinder with piston is fixed on the support and is perpendicular to the ground, the second cylinder with piston parallel to the ground is connected with the upper end of the piston rod of the first cylinder, and one end of the piston rod of the second cylinder is connected with the belt The guide post of the guide hole is connected, one end of the piston rod of the third cylinder passes through the guide post hole and is slidably fitted with the guide post, and the fuel gun is connected with the end of the piston rod of the third cylinder.

The above-mentioned technical scheme is adopted to realize the automation of engine fuel filling and save manpower input, which is not only beneficial to saving production costs, but also the fuel filling process is not affected by human factors, so it has the advantages of simple operation and high work efficiency.

Description of drawings

Accompanying drawing is a kind of embodiment of the utility model.

In the accompanying drawings, 11 is the cylinder body of the first cylinder, 12 is the piston rod of the first cylinder, 21 is the cylinder body of the second cylinder, 22 is the piston rod of the second cylinder, 31 is the piston rod of the third cylinder, 4 is a bearing, 5 is a guide column, and 6 is a refueling gun.

Detailed ways

With reference to accompanying drawing, the cylinder block 11 of the first air cylinder that has piston is fixed on the support 4 and is perpendicular to the ground, and support 4 is that can do circumferential rotation, is used for adjusting the direction of whole refueling mechanism. The piston rod of the first cylinder is used to adjust the distance in the vertical direction of the refueling gun 6, and its movement stroke in the vertical direction is 0-600 mm. A second cylinder with a piston parallel to the ground is connected to the upper end of the piston rod 12 of the first cylinder, and the cylinder body 21 of the second cylinder is welded to the piston rod of the first cylinder as a second cylinder for adjusting the distance in the horizontal direction of the refueling gun The piston rod has a horizontal movement stroke of 0-400mm. A threaded segment extends from the circumferential wall of the guide column 5 with the guide hole, and the guide column is connected with the end of the piston rod 22 of the second cylinder through the threaded segment. One end of the piston rod 31 of the third cylinder passes through the hole of the guide post and is slidably fitted with the guide post, and the fuel gun 6 is connected to the end of one end of the piston rod of the third cylinder. The angle of the third cylinder block (not shown) can be adjusted for fine-tuning the distance between the oil gun and the engine oil hole. When adjusting the angle of the cylinder block of the third cylinder, the angle of the fuel gun also changes thereupon. The piston rods of the first cylinder, the second cylinder and the third cylinder are all single-rod pistons.

The executive mechanism of the utility model is controlled by the PLC to fill the engine with fuel. When the engine that needs to be filled with fuel reaches the position of the positioning cylinder, it will send a signal to the PLC after being detected by the infrared sensor, and the PLC will control the positioning cylinder to clamp the engine. After that, control the positioning cylinder to rise to the height position of the set fuel gun. The PLC controls the extension of the piston rod of the second cylinder. When the piston of the second cylinder stretches out the refueling gun and aligns with the position of the engine oil hole, the piston rod of the second cylinder extends to the right position. The PLC controls the solenoid valve for fuel filling to open, and the engine Fuel up. When the flow meter for detecting fuel detects that the fuel filling reaches the set amount, the flow meter sends out a signal, and the PLC controls to close the fuel filling solenoid valve, and the fuel filling is completed; after a delay, the PLC controls the piston rod of the second cylinder to reset, when After the piston rod of the second cylinder is in place, a release command is issued, the positioning cylinder is reset and the clamped engine is relaxed, and the engine that has been filled with fuel is released. The PLC is reset, and the next engine is released for fuel filling. In such a cycle, the engines on the production line are filled with fuel one by one.

After testing, the above-mentioned actuators are used in combination with PLC, the fuel filling volume can be adjusted in 10ml step units, and the fueling cycle is ≤10 seconds/liter (excluding auxiliary time); and the fuel filling accuracy is ±1% (plus The injection volume is more than 200ml). Therefore, the above-mentioned actuator is combined with the PLC to improve the work efficiency of fuel filling.
