Description

Technical Field

[0001] This application relates to the technical field of bearings, and in particular to an automatic grease-applying device for bearings. Background Technology

[0002] Bearings require grease, which not only lubricates the bearing but also improves its high-temperature resistance, lifespan, and wear resistance. Traditional bearing grease machines cannot guarantee a high level of cleanliness on one end face of the bearing. This is especially true in gearboxes, where some bearings have one end face exposed and requiring cleanliness, while the other end face and circumferential side require grease lubrication. Traditional bearing grease machines struggle to keep one end face clean while simultaneously coating the other end face and circumferential side with grease; therefore, improvements are needed. Summary of the Invention

[0003] The purpose of this application is to provide an automatic bearing grease application device to solve the problem that traditional bearing grease application machines have difficulty keeping one end face of the bearing clean.

[0004] The automatic bearing grease application device provided in this application adopts the following technical solution:

[0005] An automatic bearing grease application device includes a worktable, a grease application seat, a grease application groove, a grease injection mechanism for injecting grease into the grease application groove, a feeding mechanism for conveying the bearing into the grease application groove, and an assist mechanism for driving the bearing to rotate within the grease application groove.

[0006] By adopting the above technical solution, the bearing is conveyed into the grease tank by the feeding mechanism, with one end face of the bearing facing the opening of the grease tank. The grease injection mechanism injects grease into the grease tank. When the bearing enters the grease tank, under the action of gravity, the bearing squeezes the grease at the bottom of the grease tank to the space between the circumferential wall of the grease tank and the circumferential side wall of the bearing. The assist mechanism then drives the bearing to rotate counterclockwise and clockwise several times, so that the circumferential side wall and one end face of the bearing are fully coated with grease, while the end face of the bearing facing the opening of the grease tank remains clean, ensuring that one end face of the bearing always has a high degree of cleanliness, which facilitates the subsequent installation process.

[0007] Optionally, the workbench is equipped with a feeding arm, the feeding arm is equipped with a magnetic suction component, and the workbench is equipped with a rotary lifting component for driving the feeding arm to rotate and perform lifting movements.

[0008] By adopting the above technical solution, when the bearing is greased, the rotary lifting component drives the unloading arm to rotate, so that the magnetic suction component is directly above the bearing. The rotary lifting component then drives the unloading arm to descend, so that the magnetic suction component approaches the bearing and picks it up. Then, the rotary lifting component drives the unloading arm to rise and reset, and the magnetic suction component also drives the bearing to rise. Finally, the rotary lifting component drives the unloading arm to rotate and reset, and the magnetic suction component disengages from the bearing, realizing the unloading of the bearing. Moreover, the magnetic suction bearing unloading can effectively ensure that one end face of the bearing always has a high degree of cleanliness.

[0009] Optionally, the feeding mechanism includes a feeding seat disposed on the worktable, a guide component disposed on the feeding seat, and a pushing component disposed on the feeding seat. The feeding seat is provided with a feeding groove corresponding to the guide component, and the feeding seat is provided with a discharge groove corresponding to the grease tank and communicating with the feeding groove. The pushing component corresponds to the discharge groove.

[0010] By adopting the above technical solution, the bearing is transported to the feeding trough by the guide component, and the pushing component pushes the bearing in the feeding trough to pass through the feeding trough and the discharge trough in sequence, so that the bearing is moved out of the discharge trough and falls into the grease tank.

[0011] Optionally, the guiding assembly includes a plurality of guide rods disposed on the feeding seat, the plurality of guide rods being arranged at intervals along the circumference of the feeding groove, the plurality of guide rods forming a guiding channel corresponding to the feeding groove, and two guide strips being provided at intervals on one side of the feeding seat, the feeding groove and the grease groove being located between the two guide strips.

[0012] By adopting the above technical solution, the bearings can be stacked through the guide channel and enter the feeding trough in sequence under the guidance and limiting effect of the guide channel. After the bearings are moved out of the discharge trough under the action of the pushing component, the passage formed between the two guide bars can continue to guide and limit the bearings, so that the bearings can fall accurately into the grease tank.

[0013] Optionally, the pushing assembly includes a pushing block slidably connected to the feeding trough and the discharging trough, a pushing member disposed on the feeding seat and used to drive the pushing block to slide, and an infrared sensor disposed on the feeding seat and electrically connected to the pushing member.

[0014] By adopting the above technical solution, the infrared sensor detects that the bearing enters the feeding trough through the guide channel, and activates the pusher. The pusher drives the push block to enter the feeding trough in the direction of the discharge trough, pushing the bearing in the feeding trough towards the opening of the discharge trough. Then the pusher drives the push block to reset, so that the next bearing can enter the feeding trough.

[0015] Optionally, the assist mechanism includes a lifting seat slidably connected to the worktable, a pressure head rotatably connected to the lifting seat, a drive component disposed on the lifting seat and used to drive the pressure head to rotate, and a lifting component disposed on the worktable and used to drive the lifting seat to move up and down. A first pressure sensor is disposed at the bottom of the grease tank.

[0016] By adopting the above technical solution, the bearing falls into the grease groove, the first pressure sensor detects the signal, and the lifting component is activated to drive the lifting seat to descend, so that the pressure head presses the bearing. The drive component is activated and drives the pressure head to rotate clockwise and counterclockwise several times each. The pressure head also drives the bearing to rotate clockwise and counterclockwise several times each. During the rotation, the circumferential sidewall and one end face of the bearing are coated with grease to ensure that the bearing is fully greased, while the end face of the bearing facing the groove opening of the grease groove remains clean.

[0017] Optionally, the workbench is provided with a feeding plate, the feeding plate is inclined, the workbench is provided with a receiving frame corresponding to the feeding plate, the feeding plate is provided with a second pressure sensor, and a baffle is provided on one side of the feeding plate.

[0018] By adopting the above technical solution, after the bearing is greased, the drive component is turned off, and the lifting component drives the lifting seat to rise. At this time, the bearing is not subjected to the force of the pressure head. The first pressure sensor detects the decrease in gravity and sends a signal to the rotary lifting component. The rotary lifting component drives the unloading arm to rotate, so that the magnetic suction component is directly above the bearing. The rotary lifting component then drives the unloading arm to descend, so that the magnetic suction component approaches the bearing and attracts the bearing. Then the rotary lifting component drives the unloading arm to rise and reset, and the magnetic suction component also drives the bearing to rise. Finally, the rotary lifting component drives the unloading arm to rotate and reset, the magnetic suction component disengages from the bearing, and the bearing falls onto the unloading plate. The bearing moves along the inclined unloading plate to fall into the receiving frame.

[0019] The baffle can prevent the bearing from falling out from one side of the feed plate. The second pressure sensor can detect the gravity on the feed plate to identify the number of bearings. When the number of bearings reaches the limit, the second pressure sensor can control the rotating lifting component to stop working, effectively controlling the grease application rhythm of the device and preventing production accidents.

[0020] Optionally, the bottom of the grease tank is provided with a sliding groove, and the grease injection mechanism includes a grease outlet hole provided on the wall of the sliding groove, a grease injection device provided on the worktable, and a grease injection pipe connecting the grease outlet hole and the grease injection device. A support block is slidably connected in the sliding groove, and a reset member is provided for driving the support block to reset. The first pressure sensor is provided on the support block.

[0021] By adopting the above technical solution, the bearing falls into the grease groove, the bearing acts on the support block, the support block moves along the groove depth direction of the sliding groove, the reset part is subjected to force and produces elastic deformation, and has the tendency to elastically reset. At the same time, during the movement of the support block, the support block and the grease outlet hole are misaligned, and the grease injection device injects grease into the grease groove through the grease injection pipe and the grease outlet hole.

[0022] After the bearing is removed from the grease groove, the reset component elastically resets, driving the support block to reset. The support block moves until it coincides with the grease outlet and blocks the grease outlet, thus controlling the amount of residual grease in the grease groove.

[0023] Optionally, the circumferential wall of the grease groove is provided with a plurality of slots, a relief block is slidably connected in the slots, and an elastic element is provided for driving the relief block to reset. The grease seat is rotatably connected to a first gear, the support block is provided with a toothed rack that meshes with the first gear, the first gear is axially provided with a winding drum, and the winding drum and the relief block are connected by a pull rope.

[0024] By adopting the above technical solution, the support block moves into the sliding groove under the gravity of the bearing. The support block drives the first gear to rotate through the toothed rack. The first gear drives the winding drum to rotate. The winding drum winds up the pull rope to drive the relief block to move into the groove. The elastic element undergoes elastic deformation under force and maintains the tendency of elastic reset, thereby increasing the distance between the circumferential groove wall of the grease groove and the circumferential side wall of the bearing. This provides more space for grease to be contained, effectively reducing the overflow of grease from the groove opening of the grease groove, effectively reducing the adhesion of grease to the magnetic suction component and the pressure head, and ensuring that one end face of the bearing always has a high degree of cleanliness.

[0025] After the bearing is removed, the reset component drives the support block to reset, the first gear drives the winding drum to rotate, the winding drum releases the rope, and at the same time the elastic component drives the relief block to reset, which can squeeze the grease in the groove out of the groove.

[0026] Optionally, the groove wall of the groove is provided with a limiting groove, a limiting plate is slidably connected in the limiting groove, the limiting plate is provided with an arc surface, the upper grease seat is provided with a second gear, the relief block is provided with a driving tooth profile that meshes with the second gear, the limiting plate is provided with a driven tooth profile that meshes with the second gear, and the second gear is located between the driving tooth profile and the driven tooth profile.

[0027] By adopting the above technical solution, when the relief block moves into the groove, the active toothed part drives the second gear to rotate, the second gear drives the driven toothed part to move, and the driven toothed part drives the limiting plate to move. The movement of the limiting plate covers the gap between the circumferential side wall of the bearing and the circumferential groove wall of the grease groove, which can effectively prevent grease from overflowing from the groove opening of the grease groove and ensure that one end face of the bearing always has a high degree of cleanliness.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The bearing is fed into the grease tank by the feeding mechanism, with one end face of the bearing facing the opening of the grease tank. The grease injection mechanism injects grease into the grease tank. When the bearing enters the grease tank, under the action of gravity, the bearing squeezes the grease at the bottom of the grease tank to the circumferential wall of the grease tank and the circumferential side wall of the bearing. The assist mechanism then drives the bearing to rotate counterclockwise and clockwise several times, so that the circumferential side wall and one end face of the bearing are covered with grease, while the end face of the bearing facing the opening of the grease tank remains clean, ensuring that one end face of the bearing always has a high degree of cleanliness, which is convenient for subsequent installation procedures.

[0030] 2. Under the weight of the bearing, the support block moves into the sliding groove. The support block drives the first gear to rotate through the toothed rack. The first gear drives the winding drum to rotate. The winding drum winds the rope to move the relief block into the groove. The elastic element undergoes elastic deformation under force and maintains the tendency to elastically return to its original position. This increases the distance between the circumferential wall of the grease groove and the circumferential side wall of the bearing, providing more space for grease to be contained. This effectively reduces the overflow of grease from the opening of the grease groove and effectively reduces the adhesion of grease to the magnetic suction component and the pressure head, ensuring that one end face of the bearing always has a high degree of cleanliness.

[0031] 3. Through the collaborative work of various mechanisms and sensors, automated production is achieved, and the second pressure sensor on the feeding plate can effectively control the grease loading rhythm of the bearings to prevent production accidents. Attached Figure Description
