Description

Technical Field

[0001] The utility model relates to the technical field of automobile air-conditioning compressors, in particular to an oil injection control device for an automobile air-conditioning compressor production line. Background Art

[0002] Oil injection control of automotive air conditioning compressor production line refers to the control and management of the injection process of lubricating oil when producing automotive air conditioning compressors. This process is very critical because the compressor needs lubricating oil to maintain normal operation and ensure its performance and life.

[0003] After searching, the authorization announcement number CN 214456831 U discloses an automatic refueling device for an automobile air-conditioning compressor, including a workbench and a frame; a weighing device installed on the workbench; a data display device for displaying the reading of the weighing device; an oil pump and a main control unit are also provided in the workbench, and an oil suction pipe for extracting refrigeration oil and an oil filling pipe connected to the automobile air-conditioning compressor are provided connected to the oil pump. The automatic refueling device for the automobile air-conditioning compressor can operate the oil pump through the main control unit, and the automobile air-conditioning compressor can be refueled and weighed in real time by controlling the start and stop of the oil pump. In this process, the weight of the automobile air-conditioning compressor is measured by the weighing device, and the refueling amount is weighed by subtracting the initial weight to realize a fully automatic refueling process. This device can realize a fully automatic refueling process, improve refueling efficiency, and effectively improve refueling accuracy.

[0004] In the above technical solution, the oil filling amount of the device is controlled by a weighing device and a main control unit. However, in the automobile air-conditioning compressor production line, the oil filling operation is frequently and repeatedly applied, which makes the weighing device and the main control unit prone to errors and operational errors, making it difficult to accurately control the amount of oil extracted and the amount of oil filled.

[0005] Therefore, we propose an oil injection control device for an automobile air-conditioning compressor production line. Utility Model Content

[0006] The utility model mainly solves the above technical problems and provides an oil injection control device for an automobile air-conditioning compressor production line.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an oil filling control device for an automobile air-conditioning compressor production line, comprising a mobile box and an oil filling cylinder assembly arranged in the mobile box, a connecting piece is arranged on the outer side of the mobile box, and the mobile box is connected to an external mechanical control arm through the connecting piece, and the oil filling cylinder assembly comprises an oil pumping cylinder, a piston block is arranged inside the oil pumping cylinder, a piston rod is fixedly installed on the piston block, the upper end of the piston rod passes through the top surface of the oil pumping cylinder and extends vertically upward, and an oil filling pipe is arranged at the lower end of the oil pumping cylinder, and the piston block is controlled to make a piston movement in the oil pumping cylinder, so that the oil is sucked into the oil pumping cylinder, and the oil filling port on the automobile air-conditioning compressor is filled with oil through the oil filling pipe;

[0008] An oil quantity control component for controlling the oil filling quantity of the oil filling cylinder component is arranged inside the moving box.

[0009] Preferably, a fixing block is fixedly mounted on the outer side surface of the pumping cylinder, and the fixing block is fixedly mounted on the inner wall surface of the moving box, and the fixing block drives the pumping cylinder to be distributed inside the moving box.

A moving frame is commonly fixedly installed at the ends of the two groups of sliding rod sleeves which are away from each other. A protrusion is provided on the outer side surface of the moving frame, and the moving frame is fixedly connected to the piston rod via the protrusion. By controlling the up and down displacement of the moving frame, the moving frame makes piston movement with the piston block in the oil pumping cylinder. The greater the up and down displacement amplitude of the moving frame, the greater the amount of oil pumped into the oil pumping cylinder, and the more oil is discharged to the outside.

[0011] Preferably, a conical eccentric wheel for controlling the displacement amplitude of the moving frame is arranged inside the moving box, a driving sleeve is rotatably installed inside the moving box, a rotating shaft is threadedly installed on the inner end of the driving sleeve, and the conical eccentric wheel is fixedly installed on the rotating shaft.

[0017] (1) The oil injection control device of the automobile air-conditioning compressor production line controls the rotation of the driving sleeve so that the driving sleeve drives the conical eccentric wheel to make eccentric rotation through the rotating shaft. By controlling the conical eccentric wheel to make eccentric rotation, the conical eccentric wheel pushes the moving frame up and down through the sliding rod, thereby achieving the effect of the device performing reciprocating oil injection operation.

[0018] (2) The oil injection control device of the automobile air-conditioning compressor production line, when it is necessary to adjust the distribution position of the conical eccentric wheel, turn off the driving motor in the motor box so that the driving shaft sleeve is distributed in a relatively fixed state, and then turn the hand wheel to drive the rotating shaft to rotate in the driving shaft sleeve, thereby adjusting the left and right position of the conical eccentric wheel. When the end with a larger diameter of the conical eccentric wheel is distributed between the two sets of sliding rod sleeves, the conical eccentric wheel drives the movable frame to move up and down to increase the amplitude when making eccentric rotation, and vice versa.
