BRIEF DESCRIPTION OF DRAWINGS
[0011] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific drawings.
[0012] Figure 1 It is a structural schematic view of the utility model. DETAILED DESCRIPTION
[0013] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific drawings.
[0014] Referring to Figure 1 The utility model discloses an intelligent adjustable inner wall oil injection device, which comprises, from left to right, an oil injection needle 10, an oil tank 20, an oil storage cavity 30, an oil injection piston 40 and a servo cylinder 50.
[0015] The oil injection needle 10 and the oil tank 20 are connected to the oil storage cavity 30 through a first one-way valve 11 and a second one-way valve 21 respectively, the oil injection piston 40 is arranged inside the oil storage cavity 30 and is connected to a connecting rod 51 arranged on the servo cylinder 50, the oil tank 20, the servo cylinder 50 and the oil storage cavity 30 are connected to a main control board (not shown in the figure), and the main control board is connected to a PLC control system.
[0016] The utility model further comprises a pressure detection sensor 60 arranged between the oil storage cavity 30 and the first one-way valve 11 and the second one-way valve 21 and connected to the PLC control system, which is used to timely send an alarm signal to the PLC control system to stop working when misoperation or overpressure failure of the main control board occurs.
[0017] A switch valve 12 is arranged between the oil injection needle 10 and the first one-way valve 11 for replacing the oil injection needle.
[0018] The working principle of the utility model is as follows:
[0019] When the oil storage cavity 30 stores oil, the servo cylinder 50 gives the initial position signal to the main control board after being given, and the main control board transmits the information to the PLC control system to control the servo cylinder 50 to drive the connecting rod 51 to move the oil injection piston 40 backward, which will make the oil storage cavity 30 larger, and there is a cavity to produce negative pressure, under the action of negative pressure, the first one-way valve 11 is closed, and the second one-way valve 21 is opened to connect the oil tank 20, under the action of suction, the pulling lubricating oil in the oil tank 20 will quickly supplement the cavity in the oil storage cavity 30, fill the oil storage cavity, realize the oil storage operation;
[0020] When the product needs to be injected, the PLC control system is linked with the main control board, the key technical parameters are grasped, the PLC control system is calculated according to the preset condition, the push stroke of the servo cylinder 50 is determined, the connecting rod 51 drives the oil injection piston 40 to move forward by a fixed stroke, so as to realize the compression of the oil storage cavity 30, the lubricating oil stored in the oil storage tank 30 is outputted, under the action of oil pressure, the second one-way valve 21 is locked, and the first one-way valve 11 is opened, the pulling lubricating oil comes out through the first one-way valve 11 and enters the oil injection needle 10, at this time, the oil injection needle 10 will be inserted into the inner wall of the copper pipe in advance, so as to realize the intelligent quantitative oil injection operation.
