Description

Technical Field

[0001] This utility model belongs to the field of motor manufacturing technology, specifically relating to a quantitative valve oil injection mechanism. Background Technology

[0002] The production of motors involves many steps, one of the most important being the application of lubricating oil. The amount and uniformity of the lubricating oil greatly affect the yield rate of the motor. Currently, the application of lubricating oil inside the motor housing is generally done manually, using a small brush to spread the lubricating oil evenly over the inner wall of the housing. This method requires the operator to have certain experience, as too much or too little lubricating oil may be applied, or the application may be uneven, resulting in a low yield rate. Utility Model Content

[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0004] A quantitative valve injection mechanism includes a control device and a plurality of quantitative valves. The control device is connected to the quantitative valves via pipes. The mechanism also includes a frame body and an operating platform mounted on the frame body. The operating platform is rotatably connected to the injection mechanism and a drive mechanism that drives the injection mechanism to rotate.

[0005] The oil spraying mechanism includes a base and an oil spraying column fixedly connected to the base. The oil spraying column is used to spray lubricating oil outward. The oil spraying column is also provided with an inward / outward retractable brush assembly, which is used to sweep the lubricating oil evenly.

[0006] Furthermore, the driving mechanism includes a driving element and a gear element disposed at the output end of the driving element. The fuel injection mechanism is provided with teeth that match the gear element, and the driving element drives the fuel injection mechanism to rotate through the gear element.

[0007] Furthermore, the injection column is provided with a first oil groove, the inlet of which is connected to the metering valve. The injection column is also provided with several second oil grooves, which are connected to the first oil groove. After the lubricating oil passes through the first oil groove, it is sprayed out from the several second oil grooves.

[0008] Furthermore, the brush assembly includes several sets of brushes, which are evenly arranged circumferentially between the second oil grooves. Each brush has bristles, and the oil spray column has several sets of movable grooves. Each brush is fitted into a movable groove, and each movable groove has several air holes. Each air hole is connected to a metering valve through an air passage. When the air passage is open / closed, the brush can be driven to extend / retract outward / inward.

[0009] Furthermore, the oil injection column is also provided with an elastic element, one end of which abuts against the oil injection column and the other end against the brush. The elastic element is used to reset the extension and retraction position of the brush.

[0010] Furthermore, the elastic element is a spring.

[0011] Furthermore, the driving element is a motor.

[0012] The beneficial effects of this utility model are:

[0013] This invention connects to an oil spray column via a metering valve. The oil spray column has several oil grooves in the middle. In use, the motor housing is fitted onto the oil spray column, and the metering valve can spray lubricating oil out in a metered manner. At the same time, the oil spray column is also equipped with a retractable brush with bristles. The brush can be pushed out by air pressure. With rotation, the lubricating oil on the inner wall of the housing can be evenly brushed. After the air supply is cut off, the elastic element returns to its original position, which greatly improves the production efficiency of oil spraying and brushing, avoids manual oiling and brushing, and improves the yield rate.
