Description

Technical Field

[0001] This invention relates to the field of rolling bearing manufacturing technology, specifically to a device for automatically filling graphite into rolling bearings. Background Technology

[0002] Rolling bearings are common mechanical components used to support rotating shafts or bearing housings. They consist of inner and outer rings, rolling elements, and a cage. The rolling elements reduce friction and support the weight of the rotating shaft by rolling between the inner and outer rings. There are many different types of rolling bearings, including spherical roller bearings, cylindrical roller bearings, tapered roller bearings, and self-aligning roller bearings. They can withstand radial and axial loads and have high speeds and low friction. Rolling bearings are widely used in various mechanical equipment, such as automobiles, aerospace, industrial equipment, and household appliances. Their design and material selection depend on the requirements of specific applications to ensure their performance and lifespan. In the production process of rolling bearings, an automated device is needed to load graphite powder into the bearing.

[0003] In existing technologies, workers often prepare rolling bearings and graphite lubricant, position the rolling bearings on the worktable, and then use a spray gun or manual filling tool to fill the rolling bearings with graphite powder one by one. After filling the graphite powder, it is necessary to check to ensure that the filling amount is correct and to clean up any excess graphite powder. This manual filling method usually requires a lot of manpower and time, and is easily affected by human factors, including inconsistency in filling amount and low work efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automatic graphite filling device for rolling bearings, which solves the problems of inconsistent filling amounts and low working efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a device for automatically filling graphite in rolling bearings, comprising a support mechanism, a bearing during filling, and a bearing after filling. A filling mechanism is fixedly installed on both sides of the upper end of the support mechanism. The filling mechanism includes two horizontal slide rails, each with a servo motor slidably mounted on its upper end. A hopper is installed on one side of each of the two servo motors, and a filling channel is fixedly installed on one side of each of the two hoppers. A filling pressure mechanism is fixedly installed on the opposite side of each of the two hoppers. A control mechanism is installed inside the support mechanism. A positioning mechanism is fixedly installed at the upper end of the support mechanism near the middle of the filling mechanism. The positioning mechanism includes a positioning support frame. An upper drag-in cylinder is fixedly installed at the upper rear end of the support frame. A positioning cylinder is fixedly installed at the front end of the upper drag-in cylinder. An upper positioning clamp is fixedly installed at the lower end of the positioning cylinder. A lower drag-in cylinder is fixedly installed at the lower rear end of the support frame. A lower connecting block is fixedly installed at the front end of the lower drag-in cylinder. A lower positioning clamp is fixedly installed at the upper end of the lower connecting block. A bearing to be filled is engaged at the upper end of the lower positioning clamp. A cutting mechanism is fixedly installed at the front middle of the upper end of the support mechanism.

[0006] Preferably, the support mechanism includes a lower support frame, with positioning frames fixedly installed at the four outer corners of the lower end of the lower support frame, and support feet fixedly installed at the four inner corners of the lower support frame. A worktable is fixedly installed at the upper end of the lower support frame, and two horizontal slide rails are respectively slidably installed on both sides of the upper end of the worktable.

[0007] Preferably, the control mechanism includes a power distribution box, control buttons, and a touch screen, which are electrically connected to the filling mechanism and the positioning mechanism.

[0008] A method of using an automatic graphite filling device for rolling bearings, comprising the steps described above: S1: First, place the bearing to be canned into the fixture. Then press the control button to make the positioning cylinder drive the upper positioning fixture to descend, so that the upper positioning fixture and the lower positioning fixture can fix the bearing to be canned in position. S2: Start the lower and upper drag cylinders to drive the positioning cylinder and the lower connecting block to move the bearing to be filled to the filling position; S3: Start the servo motor to control the two hoppers to move towards the middle, so that the two hoppers drive the filling channel to move towards the bearing to be filled. Then the servo motor will continue to drive the filling channels at both ends to evenly pour graphite into both ends of the bearing, and ensure that the amount and tightness of the graphite poured into both ends are consistent. S4: After the graphite is filled, the servo motor stops. Then, the bearing after the graphite is filled moves forward at the output ends of the upper and lower drag cylinders. Then, the excess graphite is cut off by the canning channels on both sides and the cutting mechanism. S5: Next, control the positioning cylinder again to drive the positioning clamp to move upward, so that the positioning clamp moves upward to release the graphite bearing, and finally complete the filling.

[0009] This invention provides an automatic graphite filling device for rolling bearings. It offers the following advantages: The device places the bearing within a clamp; upon activation, the upper clamp presses down to secure the bearing. Driven by a cylinder, the secured bearing is pulled into the appropriate filling position. At this point, servo power is activated, and graphite is evenly poured into both ends of the bearing through the feed channel. The servo power setting ensures that the amount and tightness of graphite injected into both ends of the bearing are consistent. After the graphite is injected, the servo power stops, the cylinder drives again, pushing the bearing to move in the fixed material channels at both ends. Excess graphite is removed. Finally, the upper clamp is released, and the graphite bearing that has been filled is taken out, thus completing the graphite filling of the rolling bearing. This equipment can produce one graphite bearing every 15 seconds, producing more than 2,000 per day. It is equipped with precision clamps to ensure the consistency of the filled graphite size, making it suitable for mass production. At the same time, the controllability of servo filling ensures the uniformity of the filled graphite at both ends of the bearing, and the tightness of the graphite is adjustable, further ensuring the consistency of the graphite bearing quality, greatly improving production efficiency and product quality, and reducing product manufacturing costs.
