Description

Technical Field

[0001] The utility model relates to the technical field of O-rings, in particular to an automatic O-ring grease coating device. Background Art

[0002] The O-ring is a rubber sealing ring with a circular cross section, named after its O-shaped cross section. It first appeared in the mid-19th century as a sealing element for steam engine cylinders. The O-ring is cheap, easy to manufacture, reliable, and has simple installation requirements, so it is the most common mechanical design for sealing. O-rings are often used in many structures that require sealing machinery. In order to improve the performance of the O-ring during use and the smooth assembly work, the O-ring must be pre-coated with grease before assembly to achieve the effect of lubrication, protection, and improved sealing performance.

[0003] Common O-ring greasing devices are usually composed of structures such as a grease plate, a grease supply system, a drive system, a control system, and a safety protection device. First, place the O-ring on the grease plate. The grease supply system provides grease to the grease plate, and the grease plate rotates under the action of the drive system. The overall operation of the device is operated by the control system, and under the action of the safety protection device, accidents can be prevented. This is the common structure and use of the O-ring greasing device. Traditional O-ring greasing is mostly done manually. There are many uncontrollable factors that lead to uneven oil application, or the coating area is difficult to grasp and is applied to the workpiece area outside the O-ring. Moreover, for the assembly production line of parts with large consumption, manual coating is time-consuming and labor-intensive, delaying the production cycle. Some O-ring greasing devices use a three-axis manipulator to drive the glue coating machine to grease the O-ring. Although this method solves the precision control of the coating part, the equipment investment is large, and each workpiece must be clamped, which is cumbersome and inconvenient to operate. For this reason, an automatic O-ring greasing device is proposed. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides an automatic O-ring grease coating device to solve the technical problems of large equipment investment and complicated and inconvenient operation.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: an automatic O-ring grease coating device, comprising:

[0006] A lubricator, and a grease storage tank, a piston cylinder, a first spring, a grease inlet, a grease outlet and a flow regulating knob constituting the lubricator;

[0007] The base is arranged directly below the bottom of the oiler, and a grease inlet and a grease application port are respectively provided at the center of both sides of the top of the base, and a grease channel is connected between the grease inlet and the grease application port;

[0008] The push switch is arranged at the top center of the base and connected to the grease channel, and the push switch is composed of an oil tank, a connecting rod, a second spring and a screw plug;

[0009] The workpiece is arranged just above the top of the grease port, and an O-ring is added to the bottom of the workpiece. By installing the oiler on the base, the oiler can automatically supply grease to the base through the internal first spring and the piston cylinder. Insert the workpiece equipped with the O-ring into the grease port and press it to the bottom. The O-ring automatically aligns with the grease cavity. The workpiece is pressed to automatically open the press switch, and the grease automatically flows into the base. There are multiple grease channels inside the base, which can evenly flow to the O-ring from four directions and evenly apply the grease to the surface of the O-ring. The workpiece is removed and the press switch is automatically closed to cut off the oil circuit. Grease can be added to the grease storage tank through the grease nozzle. When adding grease, the pressure of the oil gun will automatically squeeze the first spring in the piston cylinder and add grease to the grease storage tank. The grease storage tank filled with grease will have pressure under the thrust of the piston cylinder. The piston cylinder has a flow adjustment knob to adjust the flow rate. The grease can automatically flow to the grease outlet through the flow adjustment knob under the thrust of the first spring. The grease outlet is connected to the base through a thread, and the grease inlet of the base is connected to the push switch through a grease channel. The push switch can control the cut-off / opening of the main channel and is in a normally closed state. The end of the main channel is connected to a grease main channel on the left and right at the same time, and the three grease main channels are connected to four branches leading to the grease chamber. The push switch closes the oil circuit under normal circumstances. When the workpiece is pressed down, the push switch is pressed down at the same time. There is an oil groove on the connecting rod of the push switch. When the oil groove drops in the pressed state, the oil circuit is connected, and the grease flows to the grease chamber through the oil circuit. When the workpiece is removed after greasing, the connecting rod will reset under the elastic force of the second spring, and the oil groove will rise above the oil circuit, automatically cutting off the oil circuit. On the one hand, automatic greasing is simple and efficient to operate, the greasing part is accurate, and the greasing amount is adjustable, which solves the problems of low efficiency, low precision, and uneven coating of manual greasing; on the other hand, it also solves the shortcomings of large investment, inconvenient clamping, and cumbersome operation of the three-axis manipulator.

The base can be fixed at a corresponding position through the connecting tube, and the rotating head can rotate on the connecting tube.

[0011] Preferably, a rotating shaft is rotatably connected to the center of the inner cavity of the connecting tube, and the bottom end of the rotating shaft passes through the inner wall of the connecting tube and extends downward, and is coaxially connected to the rotating head. The rotating head drives the rotating shaft to rotate on the connecting tube.

[0012] Preferably, the top end of the rotating shaft penetrates the inner wall of the connecting tube and extends upward, and arc-shaped rods are installed at the front and rear ends of the upper surface of the rotating shaft. The arc-shaped rods can rotate in the same direction as the rotating shaft.

[0013] Preferably, the centers of both sides of the top of the connecting tube are rotatably connected with side convex plates, which are connected to the corresponding arc rods, and an arc spring is added to one side of the side convex plate, which is connected to the corresponding part of the top of the connecting tube.
