Description

Technical Field

[0001] This application relates to the technical field of oil seal grease injection, and in particular to a grease injection machine. Background Technology

[0002] Currently, injecting grease into the bearing is a crucial step in the bearing manufacturing process. The amount and uniformity of grease injection directly affect the bearing's operating performance, noise level, and service life. Traditional grease injection methods mostly rely on manual or semi-automatic equipment. Operators need to manually pick up and place the bearing, align it with the grease injection head, inject grease, and then remove it.

[0003] Patent (CN 201412663Y) discloses an automatic grease injection machine. The patent includes a grease injection mechanism mounted on a support platform, which is fixed to an operating table. The operating table is equipped with a feeding mechanism, a panel, a limiting mechanism, a clamping and pushing mechanism, a bracket, a centering mechanism, an oil injection platform, and a discharging mechanism. The feeding mechanism is connected to the panel, which has a limiting mechanism connected to the oil injection platform. The oil injection platform has a centering mechanism and a clamping and pushing mechanism connected to the bracket. The operating table is equipped with a main control system that determines the bearing type and the amount of oil injected, and controls the limiting mechanism, the clamping and pushing mechanism, and the feeding mechanism. This equipment can automatically inject oil into different bearings using different grease injection heads through the main control system, and also limits the amount of oil injected into each type of bearing.

[0004] Regarding the aforementioned technologies, the inventors believe that there is a defect in the inability to quantitatively inject grease, which makes it impossible to guarantee the quality of the product after processing. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this application provides a grease injection machine.

[0006] This application provides a grease injection machine, which adopts the following technical solution: A grease injection machine includes a grease injection machine operating table, a grease injection platform above the operating table, a grease injection mechanism above the grease injection platform, a first weighing platform near the inlet end of the grease injection platform, a second weighing platform near the outlet end of the grease injection platform, a transmission mechanism near the inlet end of the first weighing platform, and an outlet platform near the outlet end of the second weighing platform. A clamping and pushing mechanism is provided on the operating table to sequentially place the bearing to be processed into the first weighing platform, the grease injection platform, and the second weighing platform.

[0007] By adopting the above technical solution, the feeding and discharging platforms of the grease injection machine are set at two separate ends. The first weighing platform before grease injection and the second weighing platform after grease injection respectively collect the weight of the bearing to be processed, realizing quality monitoring and ensuring that the amount of grease injected into each product is traceable and controllable. The whole machine integrates feeding, pre-weighing, transmission, grease injection, re-weighing to discharge in one go. The modules are tightly connected and operate continuously and stably, which can achieve quantitative control and improve quality.

[0008] Preferably, the grease injection platform includes a bearing support platform and a bearing lifting platform that is on the same plane as the upper surface of the bearing support platform. The upper surface of the bearing lifting platform is provided with an annular groove adapted to the bearing to be processed. A bearing lifting guide column is fixedly connected to the lower surface of the bearing lifting platform. A bearing lifting sleeve is provided below the bearing lifting guide column. A bearing lifting cylinder is provided between the bearing lifting guide column and the bearing lifting sleeve. The base end of the bearing lifting cylinder is fixedly connected to the upper surface of the bottom end of the bearing lifting sleeve. The piston end of the bearing lifting cylinder is fixedly connected to the lower surface of the bearing lifting guide column. The bearing lifting sleeve is fixedly connected to the upper surface of the grease injection machine operating table and corresponds to the position of the bearing lifting guide column. The bearing lifting guide column and the bearing lifting sleeve are in sliding fit.

[0009] By adopting the above technical solution, the annular groove on the bearing lifting platform provides precise radial positioning and stable support for the bearing to be processed, ensuring that the bearing to be processed has a consistent posture during lifting and subsequent flipping, and eliminating the hidden danger of inaccurate grease injection position caused by the flipping of the bearing to be processed.

[0010] Preferably, a bowl-shaped groove is fixedly connected to the operating platform of the grease injection machine. The bottom of the bowl-shaped groove has a corresponding bearing cutout on the bearing lifting platform. The axis of the bearing lifting guide column coincides with the center line of the bowl-shaped groove. A tilting cylinder is located on one side of the operating platform of the grease injection machine, below the bowl-shaped groove and away from it. The base of the tilting cylinder is fixedly connected to the operating platform of the grease injection machine. A tilting push rod is fixedly connected to the piston rod of the tilting cylinder to push the lower surface of the bearing to be processed, thereby driving the bearing to be processed to tilt within the bowl-shaped groove. A limit block is fixedly connected to the edge of the bowl-shaped groove away from the tilting push rod.

[0011] By adopting the above technical solution, the bowl-shaped groove, with its own arc-shaped contour, provides a completely passive receiving environment. Even if the bearing to be processed falls in with a certain deviation, it can be automatically guided to the center position of the bottom bearing hollow, ensuring precise coaxial reset with the bearing lifting guide column. This provides a high-precision benchmark for repositioning and secondary grease injection after flipping, with an extremely high fault tolerance. The flipping push rod applies force at an optimized angle of 40° to 50° with the horizontal plane. At this angle, the thrust is efficiently decomposed into a flipping torque, ensuring the reliability of the bearing to be processed flipping. The limiting block fixedly set on the edge of the bowl-shaped groove provides a reliable mechanical stop when the bearing to be processed is subjected to the flipping force, fundamentally eliminating the possibility of the bearing to be processed detaching from the bowl-shaped groove, ensuring the success rate of the flipping action and operational safety, thereby improving the continuous operational stability of the entire machine and the product qualification rate.

[0012] Preferably, the grease injection mechanism includes a grease injection mounting plate and a grease plunger pump fixedly mounted on one side of the upper end of the grease injection mounting plate. A grease injection head is provided below the grease plunger pump, and an oil release cylinder is provided between the grease plunger pump and the grease injection head. The base end of the oil release cylinder is fixedly connected to the grease plunger pump, and the piston end of the oil release cylinder is fixedly connected to the grease injection head. An oil delivery pipe is fixedly connected to the oil inlet end of the grease plunger pump, and the oil inlet end of the oil delivery pipe is connected to an external grease reservoir.

[0013] By adopting the above technical solution, the grease plunger pump and the oil release cylinder are directly fixedly connected, eliminating the connecting pipelines and intermediate links between them, and avoiding quantitative errors caused by elastic deformation or residual air bubbles in long pipelines. An independent grease reservoir continuously supplies grease through the oil delivery pipeline, ensuring the stability of the oil source for long-term continuous operation and avoiding frequent shutdowns for refilling.

[0014] Preferably, the grease injection machine operating platform is fixedly connected to the rear frame of the grease injection machine on the side near the grease injection mechanism. A grease injection lifting sleeve is fixedly installed on the upper end of the grease injection mounting plate on the side away from the grease plunger pump. A grease injection lifting guide column is slidably connected inside the grease injection lifting sleeve. The lower end of the grease injection lifting guide column is fixedly installed on the upper surface of the grease injection machine operating platform. A cylinder mounting plate is fixedly connected to the upper end of the grease injection lifting sleeve. A cylinder fixing plate is provided above the cylinder mounting plate. A grease injection lifting cylinder is provided between the cylinder mounting plate and the cylinder fixing plate. The base end of the grease injection lifting cylinder is fixedly connected to the lower surface of the cylinder fixing plate. The piston end of the grease injection lifting cylinder is fixedly connected to the upper surface of the cylinder mounting plate. The cylinder fixing plate is fixedly connected to the rear frame of the grease injection machine.

[0015] By adopting the above technical solution, the extension and retraction of the grease injection lifting cylinder can drive the entire grease injection mechanism to move up and down along the grease injection lifting guide column, thereby adjusting the distance between the grease injection head and the bearing to be processed below, so as to adapt to bearings of different thicknesses or switch the working height of the grease injection head in different processes, thus enhancing the versatility and flexibility of the equipment.

[0016] Preferably, the bearing to be processed passes sequentially through a first weighing platform, a grease injection platform, and a second weighing platform. The first weighing platform includes a first weighing plate and multiple first weighing guide posts fixedly connected to the lower surface of the first weighing plate. The first weighing guide posts are distributed around the first weighing plate. A first weighing groove is provided in the center of the first weighing platform. Multiple first weighing sleeves are provided below the first weighing guide posts. A weighing lifting cylinder is provided between the first weighing guide posts and the first weighing sleeves. The base end of the weighing lifting cylinder is fixedly connected to the first weighing sleeve. On the bottom upper surface, the piston end of the weighing lifting cylinder is fixedly connected to the lower surface of the first weighing guide column, and the lower end of the first weighing sleeve is fixedly connected to the operating table of the grease injection machine, with the first weighing sleeve and the first weighing guide column corresponding one-to-one; a first weighing base is provided above the operating table of the grease injection machine, and a first weighing sensor is provided above the first weighing base. The shape of the first weighing sensor is adapted to the shape of the first weighing channel, and the first weighing sensor can be controlled to lift and lower through the weighing lifting cylinder; the second weighing platform has the same structure as the first weighing platform.

[0017] By adopting the above technical solution, dual weighing platforms installed before and after the grease injection process constitute a complete closed-loop quality control system. The load cells are hidden under the platforms by default, and are completely physically isolated from the flow channel when not weighing, eliminating the cumulative damage to the precision sensors caused by impacts and vibrations during the transmission of the bearings to be processed, and greatly extending the service life and calibration cycle of the sensors.

[0018] Preferably, the clamping and pushing mechanism includes an upper clamping component and a lower clamping component disposed below the upper clamping component. Both the upper and lower clamping components are provided with multiple grippers, and each gripper has a gripper sleeve detachably connected to its upper end. The gripper sleeves are divided into four groups, namely a first gripper sleeve, a second gripper sleeve, a third gripper sleeve, and a fourth gripper sleeve arranged sequentially. The plane of the second gripper sleeve of the upper clamping component near the feed end is in contact with the plane of the first gripper sleeve of the lower clamping component near the discharge end. The plane of the third gripper sleeve of the upper clamping component near the feed end is in contact with the plane of the second gripper sleeve of the lower clamping component near the discharge end. The plane of the fourth gripper sleeve of the upper clamping component near the feed end is in contact with the plane of the third gripper sleeve of the lower clamping component near the discharge end.

[0019] By adopting the above technical solution, the gripping sleeves of the upper and lower rows of clamping components move alternately, forming a nearly continuous clamping and moving band in space. This structure achieves the synchronous clamping and positioning of multiple bearings to be processed in an extremely compact space, improving efficiency several times over compared to a single robotic arm handling them sequentially.

[0020] Preferably, the upper surface of the grease injection machine operating table is fixedly connected to multiple sliding plate support columns. A vertical gripping sliding plate is fixedly connected to the upper end of each sliding plate support column. The sliding plate support columns are distributed around the vertical gripping sliding plate. A vertical gripping slide rail is provided on the vertical gripping slide rail, and a vertical slider is fitted onto the vertical gripping slide rail. A third propulsion cylinder is provided between the vertical slider and the grease injection machine operating table. The base end of the third propulsion cylinder is fixedly connected to the upper surface of the grease injection machine operating table, and the piston end of the third propulsion cylinder is fixedly connected to the side of the vertical slider away from the gripping and propulsion mechanism. A horizontal gripping sliding plate is fixedly connected above the vertical slider, and a horizontal gripping slide rail is provided on the horizontal gripping sliding plate. The upper clamping assembly is fixedly connected to the side away from the gripping mechanism by a third... A slider assembly is provided, wherein a second slider assembly is fixedly connected to the side of the lower clamping component away from the gripper. Both the first and second slider assemblies are laterally slidingly engaged with the transverse gripper slide rail, and both the first and second slider assemblies include a driven slider and an active slider. A first propulsion cylinder is provided on the side of the first active slider near the feed end. The base end of the first propulsion cylinder is fixedly connected to the operating table of the grease injection machine, and the piston end of the first propulsion cylinder is fixedly connected to the side of the first active slider near the feed end. A second propulsion cylinder is provided on the side of the second active slider near the discharge end. The base end of the second propulsion cylinder is fixedly connected to the operating table of the grease injection machine, and the piston end of the second propulsion cylinder is fixedly connected to the side of the second active slider near the discharge end.

[0021] By adopting the above technical solution, the first and second propulsion cylinders drive the active sliders of the upper and lower clamping components to reciprocate on the gripping slide rail, thereby realizing the step-by-step opening and closing and movement of the two sets of clamping components. The power transmission is direct, the motion control precision is high, and the cycle of the transmission of the bearing to be processed is stable and reliable.

[0022] Preferably, a discharge cylinder is provided on the discharge platform, the base end of the discharge cylinder is fixedly connected to the discharge cylinder, and a discharge push rod is fixedly connected to the piston end of the discharge cylinder; a discharge box is provided on the side of the grease injection machine away from the discharge platform, the inlet of the discharge box corresponds to the movement direction of the discharge push rod, a discharge sensor is provided above the inlet of the discharge box, and multiple rollers are provided inside the discharge box.

[0023] By adopting the above technical solution, the discharge sensor is set above the feed inlet, which can monitor in real time whether the discharge outlet is unobstructed and the number of discharges. Once it is detected that the bearings to be processed are piled up, stuck, or the number is incorrect, it can immediately alarm the upper control system and suspend the previous process to prevent the entire line from being blocked and the equipment from being damaged due to poor discharge.

[0024] Preferably, the transmission mechanism includes multiple transmission support columns fixedly connected to the feed end of the grease injection machine operating table. A conveyor belt frame is fixedly connected to the upper end of each transmission support column. The transmission support columns are distributed around the conveyor belt frame. A first conveyor belt is provided below the conveyor belt frame away from the discharge end. A second conveyor belt is provided above the first conveyor belt. A third conveyor belt is provided below the first conveyor belt and on the side of the second conveyor belt near the discharge end. Multiple feed sensors are provided on both sides of the third conveyor belt.

[0025] By adopting the above technical solution, a three-dimensional feeding and conveying system is constructed through the first, second and third conveyor belts, which can orderly convey the bearings to be processed to the feeding end, meet the feeding needs under different production line layouts, improve the flexibility of feeding, and the feeding sensor can monitor the presence and position of the bearings to be processed on the third conveyor belt in real time, realize the automatic control of the feeding rhythm, prevent idling due to lack of material or jamming due to accumulation, and ensure the continuous and stable operation of the entire automated production line.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The bowl-shaped groove provides a completely passive and centerless receiving environment. Its inner wall's arc-shaped guide surface can automatically guide the bearing to be processed, even if it deviates slightly in any direction, to the bottom hollow center, achieving extremely high fault tolerance and reset accuracy. This is crucial for the reliable placement of the bearing after flipping. The flipping function is executed by a flipping cylinder independently mounted on the base plate. The flipping component is independently external, with a simple structure.

[0027] 2. The dual weighing platforms installed before and after the grease injection process constitute a complete closed-loop quality control system. The load cells are hidden under the platforms by default, and are completely physically isolated from the flow channel when not weighing. This eliminates the cumulative damage to the precision sensors caused by impacts and vibrations during the transmission of the bearings to be processed, greatly extending the service life and calibration cycle of the sensors.

[0036] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0037] This application discloses a grease injection machine. (Refer to...) Figure 1-2 The device includes a grease injection machine operating table 8, a grease injection platform 14 above the grease injection machine operating table 8, a grease injection mechanism 1 above the grease injection platform 14, a first weighing platform 15 near the feed end of the grease injection platform 14, a second weighing platform 16 near the discharge end of the grease injection platform 14, a transmission mechanism 17 near the feed end of the first weighing platform 15, and a discharge platform 18 near the discharge end of the second weighing platform 16. A clamping and pushing mechanism 4 is provided on the grease injection machine operating table 8 to sequentially place the bearing to be processed into the first weighing platform 15, the grease injection platform 14, and the second weighing platform 16. During operation, the conveying mechanism 17 transports the bearing 9 to be processed to the feeding position; the clamping and pushing mechanism 4 clamps the bearing 9 and moves it to the first weighing platform 15 for pre-greasing weighing to obtain tare weight data; subsequently, the clamping and pushing mechanism 4 moves the bearing 9 to the greasing platform 14, where the greasing mechanism 1 presses down to perform greasing operation; after greasing, the clamping and pushing mechanism 4 moves the bearing 9 to the second weighing platform 16 for post-greasing weighing to obtain total weight data, and calculates the actual greasing amount based on the difference between the two weighings; finally, the clamping and pushing mechanism 4 moves the bearing 9 to the discharge platform 18, where the qualified bearing 9 is discharged. These stations operate in parallel, forming a complete automated process from feeding, weighing, greasing, testing, to discharge.

[0038] Reference Figure 1-2 The device includes a grease injection machine operating platform 8, with a grease injection platform 14 and a grease injection mechanism 1 mounted above the operating platform 8.

The cylinder fixing plate 134 is fixedly connected to the rear frame 135 of the grease injection machine. During grease injection, the piston rod of the grease injection lifting cylinder 13 extends and retracts, driving the cylinder mounting plate 133 and the grease injection lifting sleeve 131 fixed thereto to move up and down along the grease injection lifting guide column 132, thereby driving the entire grease injection mechanism 1 to rise and fall, so that the bearing 9 to be processed can reach the predetermined working height for grease injection.

[0039] Reference Figure 1-2 A grease plunger pump 122 is fixedly installed on the other side of the upper end of the grease injection mounting plate 126. A grease injection head 123 is provided below the grease plunger pump 122. An oil release cylinder 124 is provided between the grease plunger pump 122 and the grease injection head 123. The base end of the oil release cylinder 124 is fixedly connected to the grease plunger pump 122, and the piston end of the oil release cylinder 124 is fixedly connected to the grease injection head 123. An oil supply pipe 121 is fixedly connected to the oil inlet end of the grease plunger pump 122. The oil inlet end of the oil supply pipe 121 is connected to the grease reservoir 125. The grease plunger pump 122 draws in grease from the grease reservoir 125 through the oil supply pipe 121 and discharges it in a metered manner. The piston rod of the oil release cylinder 124 extends and drives the grease injection head 123 to press the bearing 9 to be processed. After the grease injection is completed, the oil release cylinder 124 retracts and resets.

[0040] Reference Figure 1 and Figure 4 The grease injection platform 14 includes a bearing support platform 21 and a bearing lifting platform 214 that is on the same plane as the upper surface of the bearing support platform 21.

A bearing lifting platform 214 is located at the bottom of the bowl-shaped groove 222, corresponding to the bearing cutout 223. The axis of the bearing lifting guide column 212 coincides with the center line of the bowl-shaped groove 222. A tilting cylinder 226 is located on one side of the operating table 8, below the bowl-shaped groove 222 and away from it. The base of the tilting cylinder 226 is fixedly connected to the operating table 8, and a tilting push rod 225 is fixedly connected to the piston end of the tilting cylinder 226. The force direction of the tilting push rod 225 forms an angle of 40° to 50° with the horizontal plane. During the pushing process, the tilting push rod always contacts the lower surface of the bearing to be processed, and the contact point is higher than the tilting axis of the bearing to be processed. A limiting block 221 is fixedly connected to the edge away from the flipping push rod 225. After the bearing 9 to be processed is in place, the piston rod of the flipping cylinder 226 extends and pushes the flipping push rod 225 to move in a fixed direction. The flipping push rod 225 pushes the bearing 9 to be processed, and the limiting block 221 limits the bearing 9 to be processed, so that it flips up and down. After the flipping is completed, the bearing lifting platform 214 rises. When it rises to the position of the bearing 9 to be processed, the annular groove 211 can adjust the posture of the bearing 9 to be processed, so that the bearing 9 to be processed can be stuck in the annular groove 211 during the rise of the bearing lifting platform 214, fixing the position of the bearing 9 to be processed. When the bearing lifting platform 214 reaches the grease injection platform 14, the bearing 9 to be processed is greased a second time.

When the bearing 9 to be processed is placed on the first weighing plate 31, the piston rod of the weighing lifting cylinder 38 retracts, and the first weighing plate 31 is lowered through the first weighing guide column 35. The weighing sensor 32 supports the bearing 9 to be processed through the hollow support and weighs its weight. The first weighing platform 15 detects the weight before grease injection, and the second weighing platform 16 detects the weight after grease injection for accurate quantification.

All block groups 428 slide laterally with the transverse gripper slide rail 426, and both the first slider group 427 and the second slider group 428 include a driven slider 4271 and a driven slider 4272; a first propulsion cylinder 429 is provided on the side of the first driven slider 4272 near the feed end, the base end of the first propulsion cylinder 429 is fixedly connected to the operating table 8 of the grease injection machine, and the piston end of the first propulsion cylinder 429 is fixedly connected to the side of the first driven slider 4272 near the feed end; a second propulsion cylinder 4272 is provided on the side of the second driven slider 4272 near the discharge end. The base end of the second propulsion cylinder 420 is fixedly connected to the operating table 8 of the grease injection machine, and the piston end of the second propulsion cylinder 420 is fixedly connected to the side of the second active slider 4272 near the discharge end. When the first propulsion cylinder 429 retracts and the second propulsion cylinder 420 extends, the bearing 9 to be processed is clamped and moved forward. When the first propulsion cylinder 429 extends and the second propulsion cylinder 420 retracts, the clamping and propulsion mechanism 4 is reset. In conjunction with the third propulsion cylinder 414, the clamping and propulsion mechanism 4 is moved away from or closer to the processing area to realize the propulsion of the bearing 9 to be processed.

[0044] Reference Figure 6-7The clamping and pushing mechanism also includes an upper clamping assembly 411 and a lower clamping assembly 412 disposed below the upper clamping assembly 411. Each clamping assembly is equipped with multiple grippers, and each gripper has a detachable gripper sleeve 413 connected to its upper end. The gripper sleeves 413 are divided into four groups: a first gripper sleeve, a second gripper sleeve, a third gripper sleeve, and a fourth gripper sleeve. The plane of the second gripper sleeve of the upper clamping assembly 411 near the feed end is aligned with the plane of the first gripper sleeve of the lower clamping assembly 412 near the discharge end. The side planes are in contact with each other. The side plane of the third gripper sleeve of the upper clamping assembly 411 near the feed end is in contact with the side plane of the second gripper sleeve of the lower clamping assembly 412 near the discharge end, and so on. After the bearing 9 to be processed reaches the work station, the first propulsion cylinder 429 retracts and the second propulsion cylinder extends 420. When the piston rod extends, the upper clamping assembly 411 and the lower clamping assembly 412 move laterally relative to each other, thereby pushing the corresponding gripper sleeves 413 to move closer to each other to perform a gripping action, and vice versa.

[0045] Reference Figure 1 The upper part of the grease injection machine operating table 8 is fixedly connected to multiple conveyor support columns 61. A conveyor belt frame 62 is fixedly connected to the upper end of each conveyor support column 61. The conveyor support columns 61 are distributed around the conveyor belt frame 62. A first conveyor belt 63 is located below the discharge end of the conveyor belt frame 62. A second conveyor belt 64 is located above the first conveyor belt 63. A third conveyor belt 65 is located below the first conveyor belt 63 and near the discharge end of the second conveyor belt 64. Multiple feed sensors 66 are located on both sides of the third conveyor belt 65. During feeding, the first conveyor belt 63 conveys the bearing 9 to be processed to the second conveyor belt 64 and then to the third conveyor belt 65. The feed sensors 66 detect the incoming material status and quantity. The third conveyor belt 65 orderly feeds the bearing 9 to be processed to the gripper of the clamping and pushing mechanism 4. Positioning; At the end of the product processing flow of the grease injection machine operating table 8, there is a discharge platform 18. The discharge platform 18 is equipped with a discharge cylinder 71. The base end of the discharge cylinder 71 is fixedly connected to the discharge cylinder 71, and the piston end of the discharge cylinder 71 is fixedly connected to the discharge push rod 72. On the side of the grease injection machine operating table 8 away from the discharge platform 18, there is a discharge box 73. The inlet of the discharge box 73 corresponds to the movement direction of the discharge push rod 72. A discharge sensor 74 is provided above the inlet of the discharge box 73. Multiple rollers 75 are provided inside the discharge box 73. When discharging, the piston rod of the discharge cylinder 71 extends and pushes the finished bearing into the inlet of the discharge box 73 through the discharge push rod 72. The discharge sensor 74 detects the number of passes through. The finished bearing rolls and slides down the multiple rollers 75 inside the discharge box 73 to the collection area.

[0046] The working principle of the grease injection machine in this application is as follows: the bearing 9 to be processed is longitudinally conveyed by the first conveyor belt 63 to the second conveyor belt 64, then transversely conveyed to the third conveyor belt 65 after being turned, and then longitudinally delivered to the processing area by the third conveyor belt 65; the feed sensor 66 identifies the status and quantity of the bearing 9 to be processed; after the identification and detection are completed, the piston rod of the third propulsion cylinder 414 extends, pushing the vertical slider 424 to move along the vertical gripping slide rail 423 towards the bearing 9 to be processed, driving the transverse gripping slide plate 425 fixed above the vertical slider 424 and the upper clamping assembly 411 and lower clamping assembly 412 mounted thereon to move as a whole towards the bearing 9 to be processed, so that the two sets of clamping assemblies reach the processing area. When bearing 9 is in the gripping position, the piston rods of the first propulsion cylinder 429 and the second propulsion cylinder 420 extend relative to each other. The first propulsion cylinder 429 drives the first active slider 4272 to move along the transverse gripping slide rail 426 towards the discharge direction, and the second propulsion cylinder 420 drives the second active slider 4272 to move along the transverse gripping slide rail 426 towards the feed direction, thereby causing the upper clamping assembly 411 and the lower clamping assembly 412 to move closer to each other. During the relative movement, the gripping sleeves 413 of the upper clamping assembly 411 and the gripping sleeves 413 of the lower clamping assembly 412 alternately close, wherein the first gripping sleeve of the upper clamping assembly 411 and the first gripping sleeve of the lower clamping assembly 412 close, and the upper clamping assembly 411... The second gripper sleeve of the first clamping assembly 412 closes with the second gripper sleeve of the lower clamping assembly 412, and so on, clamping multiple bearings 9 to be processed simultaneously. Then, the first propulsion cylinder 429 and the second propulsion cylinder 420 move in the same direction, clamping the bearings 9 to be processed and stepping to the first weighing platform 15. The two clamping assemblies release and retract. The weighing platform descends, exposing the weighing sensor 32, completing the measurement of the weight of the bearings 9 to be processed before grease injection. After the measurement is completed, the clamping assembly repeats the clamping action, transferring the bearings 9 to be processed to the grease injection platform 14. The grease injection lifting cylinder 13 drives the grease injection head 123 to descend to the working position, the grease plunger pump 122 draws grease from the grease tank 125, the oil release cylinder 124 is activated, and the grease is released through the grease injection head 123. The first grease injection is completed; then, the bearing lifting platform 214 descends, and the bearing to be processed 9 falls into the bowl-shaped groove 222; the tilting cylinder 226 pushes the tilting push rod 225 to tilt the bearing to be processed 9 up and down; after the tilting is completed, the bearing lifting platform 214 rises, lifting the bearing to be processed 9 to the bearing support platform 21 for the second grease injection; after the second grease injection is completed, the clamping and pushing mechanism 4 clamps the bearing to be processed 9 and moves it to the second weighing platform 16, and weighs the greased bearing according to the same steps, and calculates the amount of grease injected by the difference in weight before and after; after the inspection is completed, the clamping and pushing mechanism 4 transports the processed bearing to the front of the discharge box 73, and pushes it into the discharge box 73 by the discharge push rod 72, entering the bearing collection area.
