Description

Technical Field

[0001] The invention relates to the technical field of bearing processing, in particular to bearing processing grease injection equipment and a grease injection method. Background Art

[0002] The function of bearing processing grease injection equipment is to ensure that the inside of the bearing can be accurately and evenly filled with grease, thereby effectively reducing friction and wear and extending the service life of the bearing; the structure of this type of grease injection equipment includes several key parts such as grease supply system, grease injection head, pressure control system, bearing clamping device, control system and sealing device, among which the storage, transportation and precise injection process of grease is the core link. The grease is transported from the storage bin through the filtration system to the grease injection head, and then the grease is injected into the bearing through a precision control system to ensure that the grease amount and distribution meet the technical requirements.

[0003] As disclosed in Chinese invention patent CN117450178A, the bearing processing grease injection equipment comprises a first conveyor belt and two symmetrically arranged fixed frames arranged on one side of the first conveyor belt, the surface of the first conveyor belt is fixedly connected with a guide plate, one side of the guide plate is rotatably connected with an adjustment plate through a rotating cylinder, the surfaces of the two fixed frames are both provided with a second conveyor belt connected to the first conveyor belt, and the top of the fixed frame is fixedly connected with a vibrating frame passing through the middle of the second conveyor belt; the grease injection equipment has low grease injection efficiency and poor grease injection effect.

[0004] For example, Chinese invention patent CN114576276B relates to the technical field of bearing production equipment, and discloses a fully automatic bearing grease injection and capping machine, in which a circular processing disk is movably installed at the top center of a support base, support frames are fixedly installed on both sides of the top of the support base, a controller is fixedly installed at the center of the support frame, and an electric push rod device is fixedly installed on one side of the center of the support frame; the grease injection device is difficult to operate and has low operating accuracy.

[0005] During use, the grease injection equipment in the above technical solution can only inject grease and discharge materials at a single point, such as the gap between the inner ring and outer ring of the bearing. The working principle is to inject grease into the inside of the bearing through a pressure control system, and the grease injection head is precisely positioned at a specific position of the bearing. The injection of grease is mainly concentrated in these limited points, and it is difficult to ensure that the grease can penetrate into other parts of the bearing, especially the contact area between the rolling elements and the raceways of the bearing. Even if the bearing is vibrated during the grease injection process, inertia and external force are used to assist the distribution of grease, the distribution of grease inside the bearing is still not uniform due to the viscosity of the grease, the structure of the bearing and the limitation of the vibration amplitude.

[0006] At the same time, since grease itself has adhesion, when the amount of grease inside the bearing gap changes, if the subsequent grease injection amount cannot be adjusted in time, it will easily reduce the normal grease injection effect of the bearing, thereby affecting the subsequent use of the bearing.

[0007] After grease is injected into the bearing gap, different amounts of grease are likely to remain on the top of the bearing (it is best to keep it uniform throughout the entire piece). If it is not scraped off thoroughly, it will not only reduce the cleanliness of the bearing's outer surface, but also affect the subsequent grease injection amount. Summary of the invention

[0008] The object of the present invention is to provide a bearing processing grease injection device and a grease injection method to solve the problems raised in the above background technology.

[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a bearing processing grease injection device, comprising a grease injection platform, a matrix co-transformation bearing rotation module for driving a plurality of bearing workpieces to rotate together is arranged on the top of the grease injection platform, a pulley driving unit is arranged on one side outer wall of the grease injection platform, two symmetrical right-angle support frames are integrally formed on one side of the top of the grease injection platform, a mountain-shaped arm is slidably installed on the outer wall of one side of the two right-angle support frames close to the matrix co-transformation bearing rotation module, and a lifting and lowering grease pressing module is installed on the outer wall of one side of the mountain-shaped arm, a reciprocating traction module for driving the lifting and lowering grease pressing module to reciprocate in the Y-axis direction is installed at the bottom end of one of the right-angle support frames, and an adjustable grease injection module for supplying lubricating grease to the bearing raceway is installed at the top of the grease injection platform; The matrix co-rotating bearing rotation module includes a vertical shaft, a first pulley transmission structure, a second pulley transmission structure, a lifting chuck and a pressure sensor; The reciprocating traction module includes a transmission shaft rotatably installed on the top of one of the right-angle support frames, a turntable fixed at the bottom of the transmission shaft, a pneumatic telescopic rod arranged on the outer surface of the transmission shaft, and a swing arm hingedly installed on one side of the top of the right-angle support frame, and a convex column is fixed at the output end of the pneumatic telescopic rod.

[0016] Preferably, the lifting and lowering grease pressing module includes a right-angle cylinder seat installed on one side of the top end of the mountain-shaped arm, a cylinder installed on the outer wall of one side of the right-angle cylinder seat, and a U-shaped long arm fixed to the bottom end of the cylinder piston rod. The U-shaped long arm is made of a hard plastic component, and the lower surface of the U-shaped long arm is smooth and free of burrs. A steel column is installed on the top of the U-shaped long arm, and the top of the steel column penetrates upward to the outside of the right-angle cylinder seat. Two limit rods are symmetrically arranged on both sides of the right-angle cylinder seat, and limit grooves are provided on the tops of the two right-angle support frames, which are connected to the limit rods in a limited sliding manner.

[0017] Preferably, the adjustable grease injection module includes a bidirectional screw linear module installed on the top of the grease injection platform, a U-frame installed at the two moving ends of the bidirectional screw linear module, and a connecting plate installed on the left and right outer walls of the U-frame, a circular feed pipe is installed inside the connecting plate, and an electromagnetic switch valve is installed at the end of the circular feed pipe close to the U-shaped long arm, and a right-angle grease injection nozzle is installed at the outlet end of the electromagnetic switch valve.

[0019] According to the grease injection method of the bearing processing grease injection equipment, the following steps are included: S101: A portion of the rotational power of the pulley drive unit is transmitted to the matrix co-rotating bearing rotation module through the bevel gear reversing transmission and drives multiple bearing workpieces to rotate. The grease supplied by the adjustable grease injection module is automatically injected into various parts of the bearing raceway, and the distribution of the grease is affected by the centrifugal force to ensure that the grease can evenly cover the inside of the bearing; S102: During the grease injection process, the lifting and lowering grease pressing module presses the grease into various gaps inside the bearing, and the reciprocating traction module synchronously receives the rotary power from the bevel gear reversing transmission to make the lifting and lowering grease pressing module reciprocate and slide on the top of the bearing workpiece.

[0020] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, compared with the traditional static grease injection method, the grease can more easily penetrate into various small areas inside the bearing due to the action of inertia and centrifugal force during the rotation of the bearing. In particular, for the contact area inside the bearing, the rotation can make the grease evenly distributed, avoiding the problem of uneven grease distribution caused by a single grease injection point. This can not only significantly improve the lubrication effect of the bearing, but also reduce local overheating, wear and corrosion problems caused by uneven lubrication.

[0021] 2. In the present invention, the adjustable grease injection module adjusts the grease injection point. The grease injection module can select the most suitable position for grease injection according to the specific needs of each bearing to ensure that the grease is accurately injected into the key parts of the bearing, avoiding the disadvantages of fixed injection position and uneven grease distribution in the traditional grease injection method.

[0022] 3. In the present invention, especially for some high-precision, high-load bearings, sufficient injection of grease can effectively reduce friction, lower temperature, and extend the service life of the bearings. Moreover, since the grease is repeatedly pressed into and evenly distributed in the bearings, the distribution of the grease can maintain a relatively balanced distribution even in complex working environments such as high temperature and high speed.

[0023] 4. In the present invention, the amount of grease injected into the bearing gap and the scraping distance of the U-shaped long arm are adjusted according to the pressure value detected by the pressure sensor, thereby ensuring that the amount of grease injected into the bearing remains uniform and stable at all times, further improving the injection accuracy and injection effect of the grease, and improving the lubrication transmission stability of the bearing.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment 1 Depend on Figures 1 to 8 It is given that the bearing processing grease injection equipment includes a grease injection platform 1, and the top of the grease injection platform 1 is provided with a matrix co-transformation bearing rotation module 6 for driving a plurality of bearing workpieces to rotate together. The matrix co-transformation bearing rotation module 6 rotates and drives the bearing to rotate, thereby realizing complete grease injection for the bearing. One side of the top of the grease injection platform 1 is integrally formed with two symmetrical right-angle support frames 2, and a mountain-shaped arm 7 is slidably installed on the outer wall of one side of the two right-angle support frames 2 close to the matrix co-transformation bearing rotation module 6, and a lifting and lowering grease module 8 is installed on the outer wall of one side of the mountain-shaped arm 7, wherein A reciprocating traction module 9 is installed at the bottom end of a right-angle support frame 2 for driving the lifting and grease pressing module 8 to slide back and forth in the Y-axis direction. The reciprocating traction module 9 drives the mountain-shaped arm 7 to slide back and forth, and the reciprocating sliding of the mountain-shaped arm 7 synchronously drives the lifting and grease pressing module 8 to slide back and forth, thereby achieving uniform pressing and flattening of the bearing above the matrix co-transformation bearing rotating module 6. An adjustable grease injection module 10 is installed on the top of the grease injection platform 1 for supplying lubricating grease to the bearing raceway. The adjustable grease injection module 10 can adjust the grease injection position and grease injection amount of the bearing accordingly.

[0028] A pulley drive unit 4 is arranged on the outer wall of one side of the grease injection platform 1, and a bevel gear reversing transmission 3 for receiving the rotation force from the pulley drive unit 4 is installed on one side of the top of the grease injection platform 1, and the two output shafts of the bevel gear reversing transmission 3 are respectively connected with the matrix co-rotating bearing rotation module 6 and the reciprocating traction module 9, so that the pulley drive unit 4 is started and drives the matrix co-rotating bearing rotation module 6 and the reciprocating traction module 9 to work continuously through the steering transmission of the bevel gear reversing transmission 3, and a PLC control panel 5 is installed on the outer wall of the grease injection platform 1 on one side of the pulley drive unit 4, and the output end of the PLC control panel 5 is electrically connected with the input end of the pulley drive unit 4, the lifting and lowering grease module 8 and the adjustable grease injection module 10.

[0029] The matrix co-rotating bearing rotation module 6 includes a vertical shaft 601, a first pulley transmission structure 602, a second pulley transmission structure 603, a lifting chuck 604 and a pressure sensor 605. The pressure sensor 605 is used to detect the pressure value at the top of the lifting chuck 604. Several vertical shafts 601 are rotatably installed at equal intervals on the top of the grease injection platform 1. The lifting chuck 604 can move up and down on the top of the grease injection platform 1, thereby driving the bearing to move up and down, so that the top of the bearing and the height of the bidirectional screw linear module 1001 are at the same horizontal plane. The first pulley transmission structure 602 is set at the bottom end of several vertical shafts 601 in the X-axis direction, the second pulley transmission structure 603 is set at the bottom end of several vertical shafts 601 in the Y-axis direction, and the lifting chuck 604 is fixed on the top of the vertical shaft 601.

[0030] The staff places the bearing workpiece to be greased on the lifting chuck 604, and clamps the workpiece using the lifting chuck 604 to keep the bearing stable. At the same time, the pressure sensor 605 above the lifting chuck 604 detects the pressure values ​​at different positions of the bearing, thereby obtaining the clamping accuracy of the bearing above the lifting chuck 604 and the gravity uniformity of the bearing itself. Then the staff turns on the pulley drive unit 4 through the PLC control panel 5 to work, and uses the pulley drive unit 4 and the bevel gear reversing transmission 3 to drive a vertical shaft 601 in the matrix co-transformation bearing rotation module 6 to rotate. At this time, several vertical shafts 601 in the X-axis direction maintain power connection through the first pulley transmission structure 602, and multiple vertical shafts 601 in the Y-axis direction maintain power connection through the second pulley transmission structure 603. In this way, the vertical shaft 601 is used to drive the lifting chuck 604 and the bearing workpiece to rotate, thereby changing the position of the bearing raceway and the adjustable grease injection module 10, so that the grease supplied by the adjustable grease injection module 10 is evenly covered at various positions of the raceway.

[0031] The top end of one of the vertical shafts 601 is fixedly connected to an output shaft of the bevel gear reversing transmission 3 through a coupling. The matrix co-rotating bearing rotation module 6 controls multiple bearings to rotate at the same time and speed through precise rotation, ensuring that the grease can evenly cover all contact surfaces. The rotation of the bearing in this process makes the grease more evenly distributed inside the bearing, and the centrifugal force can also effectively push the grease to each contact point of the bearing, ensuring a better lubrication effect.

[0032] The pulley drive unit 4 includes a stepper motor installed on the outer wall of one side of the grease injection platform 1, a driving pulley installed on the output end of the stepper motor, and a driven pulley installed on the input shaft of the bevel gear reversing transmission 3. A belt is installed between the driven pulley and the driving pulley. The pulley drive unit 4 transmits power through the belt and the pulley, has a high transmission efficiency, can stably transmit power to each module that needs to be driven, and ensure the normal operation of the entire equipment; and the bevel gear reversing transmission 3 can achieve precise steering of power through the design of bevel gears, so that the equipment can operate in multiple directions without changing the overall layout.

[0033] The lifting and lowering grease pressing module 8 includes a right-angle cylinder seat 801 installed on one side of the top of the mountain-shaped arm 7, a cylinder 802 installed on the outer wall of one side of the right-angle cylinder seat 801, and a U-shaped long arm 803 fixed at the bottom end of the piston rod of the cylinder 802. The U-shaped long arm 803 is made of a hard plastic component. The lower surface of the U-shaped long arm 803 is smooth and has no burrs. A steel column is installed on the top of the U-shaped long arm 803, and the top of the steel column penetrates upward to the outside of the right-angle cylinder seat 801. When the lifting and lowering grease pressing module 8 and the reciprocating traction module 9 are working, the staff controls the cylinder 802 to work through the PLC control panel 5, and the cylinder 802 drives the U-shaped long arm 803 to lift and lower to control the Z-axis height of the U-shaped long arm 803 until the lower surface of the U-shaped long arm 803 contacts the upper surface of the bearing, and the U-shaped long arm 803 is used to press the grease into the inside of the bearing, thereby helping the grease to penetrate into the deep layer of the bearing, ensuring that the grease can completely fill all the gaps inside the bearing and improve the lubrication effect.

[0034] Two limit rods are symmetrically arranged on both sides of the right-angle cylinder seat 801, and limit grooves are provided on the tops of the two right-angle support frames 2. The limit grooves are connected to the limit rods in a limited sliding manner. The sliding cooperation between the limit grooves and the limit rods further improves the sliding accuracy and stability of the right-angle cylinder seat 801, avoids the deviation of the right-angle cylinder seat 801 and reduces the subsequent cleaning effect of scraping the reciprocating sliding of the U-shaped long arm 803.

[0035] The reciprocating traction module 9 includes a transmission shaft 901 rotatably mounted on the top of one of the right-angle support frames 2, a turntable 903 fixed at the bottom of the transmission shaft 901, a pneumatic telescopic rod 908 arranged on the outer surface of the transmission shaft 901, and a swing arm 905 hingedly mounted on one side of the top of the right-angle support frame 2. A protruding column 904 is fixed to the output end of the pneumatic telescopic rod 908. Therefore, when the pneumatic telescopic rod 908 is started and the output end is extended, the output end of the pneumatic telescopic rod 908 drives the protruding column 904 to move away from the transmission shaft 901 end. A straight slot 907 is arranged inside the swing arm 905 for the protruding column 904 to pass through. The protruding column 904 rotates with the transmission shaft 901. When the gear 905 is in motion, it cooperates with the straight slot 907 and drives the swing arm 905 to swing back and forth continuously. The top of the transmission shaft 901 is equipped with a bevel gear transmission structure 902 which is interconnected with another output shaft of the bevel gear reversing transmission 3. The bevel gear reversing transmission 3 works and drives the transmission shaft 901 to rotate continuously through the bevel gear transmission structure 902, thereby realizing the subsequent reciprocating swing of the swing arm 905. A slide groove is provided at the bottom of the turntable 903, and the top of the boss 904 is slidably connected to the inner wall of the slide groove. The boss 904 cooperates with the slide groove and further improves the stability and synchronization of the boss 904 as the transmission shaft 901 rotates under the drive of the pneumatic telescopic rod 908.

[0036] A T-shaped shaft 701 is fixed to one side of the bottom end of the mountain-shaped arm 7, and a U-shaped slot 906 is provided at one end of the swing arm 905 close to the mountain-shaped arm 7. The bottom end of the T-shaped shaft 701 penetrates to the outside of the U-shaped slot 906 and slides with the swing arm 905. The swing arm 905 rotates continuously and drives the U-shaped slot 906 to swing back and forth. The U-shaped slot and the T-shaped shaft 701 transmit transmission to each other and drive the mountain-shaped arm 7 to slide back and forth laterally.

[0037] When the pulley drive unit 4 and the bevel gear reversing transmission 3 are working, a part of the rotational power of the bevel gear reversing transmission 3 will be transmitted to the transmission shaft 901 through the bevel gear transmission structure 902, and the transmission shaft 901 will drive the turntable 903 to rotate. At this time, the boss 904 is driven to rotate around the turntable 903 under the limiting effect of the slide groove. Since the boss 904 is located in the straight groove 907, the swing arm 905 will reciprocate and swing with the cooperation of the boss 904 and the straight groove 907, and the swing arm 905, the T-shaft 701, the U-slot 906 are used to force the mountain arm 7, the right-angle cylinder seat 801, the U-shaped long arm 803 and other components to slide back and forth in the X-axis direction.

[0038] At the same time, when it is necessary to increase the reciprocating sliding distance of the U-shaped long arm 803, it is only necessary to start the pneumatic telescopic rod 908 and drive the boss 904 to move away from the end of the transmission shaft 901. When the transmission shaft 901 rotates, the boss 904 is driven to increase the rotation range through the turntable 903, and the boss 904 drives the swing arm 905 to increase the swing range. The swing arm 905 drives the mountain arm 7, the right-angle cylinder seat 801, the U-shaped long arm 803 and other components to increase the reciprocating sliding distance in the X-axis direction, so that the grease can be further applied to the bearing to avoid the accumulation of grease in certain local positions, ensure the uniform distribution of grease, and avoid excessive concentration of grease in a certain part to cause poor lubrication.

[0039] The adjustable grease injection module 10 comprises a bidirectional screw linear module 1001 installed on the top of the grease injection platform 1, a U-shaped frame 1002 installed at the two moving ends of the bidirectional screw linear module 1001, and a connecting plate 1003 installed on the left and right outer walls of the U-shaped frame 1002, a round-shaped feed pipe 1004 is installed inside the connecting plate 1003, and an electromagnetic switch valve 1005 is installed at one end of the round-shaped feed pipe 1004 close to the U-shaped long arm 803, and a right-angle grease injection nozzle 1006 is installed at the outlet end of the electromagnetic switch valve 1005, and the two moving ends of the bidirectional screw linear module 1001 are controlled by the bidirectional screw linear module 1001. The U-frames 1002 move toward each other in the Y-axis direction to adjust the positions of the electromagnetic switch valve 1005 and the right-angle grease nozzle 1006 in the Y-axis direction, so that the grease injection point of the right-angle grease nozzle 1006 on the raceway can be adjusted. At this time, the grease delivery pump connected to the circular feed pipe 1004 can inject grease into the electromagnetic switch valve 1005 and the right-angle grease nozzle 1006, and deliver the grease into the bearing. It can accurately control the amount of grease injected into each bearing according to the different models and specifications of the bearings by adjusting the pressure and grease injection angle of the grease injection module.

[0040] Two recycling boxes 11 are symmetrically arranged on the top of the grease injection platform 1 and on both sides of the two-way screw linear module 1001. The other side of the recycling box 11 matches the side wall of the lifting chuck 604. The recycling box 11 is used to recycle the grease scraped off by the U-shaped long arm 803. The input end of the circular feed pipe 1004 is connected to the recycling box 11. Grease is arranged inside the recycling box 11. The grease inside the recycling box 11 continues to flow along the circular feed pipe 1004 to the electromagnetic switch valve 1005 and the right-angle grease injection nozzle 1006 to realize the grease injection process of the bearing. At the same time, the amount of grease inside the recycling box 11 is large during actual use. Therefore, the synchronous grease injection process of multiple greases can be realized, which effectively improves the grease recovery effect and avoids the waste of grease caused by long-term use.

[0041] When the embodiment of the present application is in use, first check whether the grease injection platform 1 is in the correct position, and ensure whether the material in the grease delivery pump and the grease storage device connected to the adjustable grease injection module 10 is sufficient and free of impurities, and check whether the pulley drive unit 4 and the bevel gear reversing transmission 3 are operating normally to ensure that the power source is reliable. At the same time, the cylinder 802 drives the U-shaped long arm 803 to move upward to the initial height, and the bidirectional screw linear module 1001 drives the circular feed pipe 1004 to move to the initial position on both sides through the U-shaped frame 1002 and the connecting plate 1003, and the lifting chuck 604 moves downward to the lowest value, thereby facilitating the subsequent placement and greasing of the bearings.

[0042] After the equipment inspection is completed, the staff will correctly place the multiple bearing workpieces to be greased on the workstation of the matrix co-transformed bearing rotation module 6 one by one. The pressure sensor 605 detects the pressure value of the bearing. This pressure value can not only obtain the bearing size, but also adjust the bearing position accordingly to ensure the coaxiality of the bearing and the lifting chuck 604, and start the adjustable grease injection module 10 through the PLC control panel 5. During this process, the staff sets the appropriate grease injection points of the adjustable grease injection module 10 according to the specifications of the bearing to ensure that the grease can be accurately injected into the bearing.

[0043] After confirming that the equipment is set up, the staff starts the greasing process. At this time, the PLC control panel 5 controls the lifting chuck 604 to move upward and drive the top of the bearing to the same horizontal plane as the top of the bidirectional screw linear module 1001, thereby facilitating the subsequent reciprocating lateral movement of the U-shaped long arm 803 and greasing the bearing.

[0044] Afterwards, the PLC control panel 5 starts the pulley drive unit 4 to work, and a part of the rotational power of the pulley drive unit 4 is transmitted to the matrix co-rotating bearing rotation module 6 through the bevel gear reversing transmission 3, and then multiple bearing workpieces rotate, and the grease supplied by the adjustable grease injection module 10 is automatically injected into various parts of the bearing raceway, and the distribution of the grease will be affected by the centrifugal force, ensuring that the grease can evenly cover the raceway, rolling elements and other contact areas, and achieve the ideal lubrication effect. The staff can observe the grease injection process to ensure that the grease flow is normal and the grease injection points are accurate to avoid excessive or insufficient grease injection.

[0045] And when the diameter of the bearing increases, the PLC control panel 5 controls the bidirectional screw linear module 1001 to start and drive the U-frame 1002 and the connecting plate 1003 to move away from each other, and the connecting plate 1003 drives the circular feed tube 1004, the electromagnetic switch valve 1005 and the right-angle grease nozzle 1006 to move away from each other. The right-angle grease nozzle 1006 continuously moves to the grease injection position of the bearing, and this position is part of the bearing gap and the top of the bearing. The pressure value detected by the pressure sensor 605 reaches the set pressure preset value, which further improves the accuracy and positioning of the grease injection, as well as the convenience and efficiency of the subsequent pressure injection and scraping cleaning of the bearing.

[0046] During the grease injection process, the staff needs to ensure the coordinated operation of the lifting and lowering grease pressing module 8 and the reciprocating traction module 9. The lifting and lowering grease pressing module 8 will press the grease into various gaps inside the bearing by moving up and down to ensure that the grease can penetrate into the deep layer of the bearing, while the reciprocating traction module 9 synchronously receives the rotational power from the bevel gear reversing transmission 3, and can make the lifting and lowering grease pressing module 8 reciprocate on the top of the bearing workpiece, thereby alleviating the accumulation of grease in certain parts and avoiding excessive waste or accumulation of grease.

[0047] Specifically, the PLC control panel 5 controls the electromagnetic switch valve 1005 to open, and the grease inside the recovery box 11 is sprayed downward into the bearing gap along the right-angle grease injection nozzle 1006 through the circular feed pipe 1004. At the same time, the pulley drive unit 4 is started and drives the vertical shaft 601 at the end to rotate through the bevel gear reversing transmission device 3, and the vertical shaft 601 at the end drives the remaining vertical shafts 601 to rotate synchronously through multiple first pulley transmission structures 602 and second pulley transmission structures 603. The vertical shaft 601 drives the top lifting chuck 604 to rotate, and the lifting chuck 604 drives the bearing to rotate and realizes the subsequent grease injection process. At the same time, when the bevel gear reversing transmission device 3 is working, it drives the transmission shaft 90 through the bevel gear transmission structure 902 1 rotates, the transmission shaft 901 drives the turntable 903 to rotate, the turntable 903 drives the swing arm 905 to swing back and forth through the convex column 904, the swing arm 905 drives the mountain arm 7 to move back and forth laterally with the help of the U-notch 906 and the T-axis 701, the mountain arm 7 synchronously drives the U-shaped long arm 803 to move back and forth laterally and presses and scrapes the grease on the top of the bearing to improve the uniformity of the grease distribution inside the bearing, and during the reciprocating lateral sliding of the U-shaped long arm 803, its bottom and the top of the two-way screw linear module 1001 are scraped, so that the excess grease is returned to the inside of the recovery box 11 to wait for the subsequent grease injection process, further improving the recycling and reuse effect of the grease and improving the recycling effect.

[0048] At the same time, the rotation direction of the bearing driven by the lifting chuck 604 is opposite to the moving scraping direction of the U-shaped long arm 803, and the U-shaped long arm 803 is not located at the axis of the bearing, and the U-shaped long arm 803 and the right-angle grease injection nozzle 1006 are symmetrically distributed along the vertical plane of the bearing. This arrangement realizes the process that the bearing is first injected with glue by the right-angle grease injection nozzle 1006 and then rotated 180 degrees and then scraped and cleaned by the U-shaped long arm 803. It has stronger operability and higher stability. When the U-shaped long arm 803 moves to the right and scrapes and cleans the top of the bearing, there is residual grease at the bottom of the U-shaped long arm 803, then the lifting chuck 60 4 is started and drives the bearing to move downward. At this time, the bottom of the U-shaped long arm 803 is not squeezed and contacted with the top of the bearing. At this time, as the U-shaped long arm 803 moves to the left and returns to its original position, the bottom of the U-shaped long arm 803 and the side wall of the recovery box 11 squeeze and scrape each other and scrape the residual grease back to the inside of the recovery box 11, thereby realizing efficient and clean recovery of the grease. After that, the U-shaped long arm 803 continues to move to the right, and the lifting chuck 604 drives the bearing to move upward to restore the height while rotating 180 degrees, and the above process is repeated continuously, thereby realizing the continuous grease injection and scraping cleaning process inside the bearing.

[0049] As grease is continuously injected into the bearing gap, the pressure value detected by the pressure sensor 605 after the top of the bearing is scraped and cleaned by the U-shaped long arm 803 increases evenly with the increase in the number of rotations of the bearing, and the difference in the pressure values ​​is equal, thereby achieving the effect of layer-by-layer grease injection on the bearing. However, when the pressure difference detected by the pressure sensor 605 at a certain time is greater than the preset pressure difference set for that time, it means that the amount of grease inside the bearing gap is too large at this time. If the same amount of grease is still injected into the bearing gap, it is easy to cause the bearing to slip at that position. Problems.

[0050] Therefore, the PLC control panel 5 controls the bidirectional screw linear module 1001 to start and drive the multiple U-frames 1002 and connecting plates 1003 on both sides to move away from each other. The connecting plate 1003 drives the circular feed pipe 1004, the electromagnetic switch valve 1005 and the right-angle grease nozzle 1006 to move away from each other. The right-angle grease nozzle 1006 is no longer directly facing the bearing gap. When the bearing continues to rotate with the lifting chuck 604 and reaches below the right-angle grease nozzle 1006, part of the grease discharged downward by the right-angle grease nozzle 1006 falls inside the gap, and the other part of the grease falls on the top of the bearing, thereby reducing the amount of grease that falls directly into the gap, ensuring that after the subsequent U-shaped long arm 803 presses the grease into the bearing gap, the amount of grease inside the bearing meets the actual processing and production needs.

[0051] When the pressure difference detected by the pressure sensor 605 increases, and the multiple right-angle grease nozzles 1006 move away from each other, the PLC control panel 5 controls the output end of the pneumatic telescopic rod 908 to extend, and the pneumatic telescopic rod 908 drives the protruding column 904 to move along the slide groove at the bottom of the turntable 903 away from the transmission shaft 901 end. When the transmission shaft 901 drives the protruding column 904 to rotate through the turntable 903, the reciprocating swing range of the swing arm 905 is increased, and the other end of the swing arm 905 drives the mountain-shaped arm 7 to reciprocate and slide horizontally through the U-shaped groove 906 and the T-shaped shaft 701. The mountain-shaped arm 7 drives the U-shaped long arm 803 to increase its reciprocating lateral sliding distance, and the lateral scraping distance between the bottom of the U-shaped long arm 803 and the top of the bearing increases, thereby improving the scraping effect of the grease on the top of the bearing, ensuring the uniformity of the grease inside the bearing gap and the cleanliness of the top of the bearing, avoiding affecting the grease injection effect of the bearing, and the U-shaped long arm 803 reciprocates and moves laterally and scrapes with the top of the bidirectional screw linear module 1001, thereby returning the excess grease to the inside of the recovery box 11 and performing subsequent grease injection processes, effectively improving the grease recovery effect.

[0052] Afterwards, the lifting chuck 604 drives the bearing to continue rotating. At this time, the pressure difference detected by the pressure sensor 605 decreases, and the sum of this pressure difference and the previous pressure difference is equal to twice the set pressure difference preset value, thereby completing the adjustment of the bearing gap grease amount to ensure the uniformity and synchronization of the bearing grease injection.

[0053] Similarly, when the pressure difference detected by the pressure sensor 605 of the bearing after scraping by the U-shaped long arm 803 is less than the preset difference, the PLC control panel 5 controls the multiple right-angle grease nozzles 1006 to move towards each other, and the amount of grease injected downward into the bearing gap by the right-angle grease nozzle 1006 increases. At the same time, the output end of the pneumatic telescopic rod 908 is shortened, and the pneumatic telescopic rod 908 drives the boss 904 to move closer to the end of the transmission shaft 901. The corresponding reciprocating lateral movement distance of the U-shaped long arm 803 is reduced, thereby ensuring the pressing of the bearing gap grease and the scraping and cleaning of the oil tank on the top of the bearing. The excess grease at the bottom of the U-shaped long arm 803 and the side wall of the two-way screw linear module 1001 are scraped off and returned to the inside of the recycling box 11, which has higher adaptability, better cleanliness and stronger recycling effect.

[0054] During the operation of the equipment, the operating frequencies of the matrix co-rotating bearing rotation module 6 and the reciprocating traction module 9 are proportional. According to the working environment of the bearing, such as high speed and high temperature, the operating parameters of the matrix co-rotating bearing rotation module 6 and the reciprocating traction module 9 are flexibly adjusted through the pulley drive unit 4 and the bevel gear reversing transmission 3 to ensure that the injection of grease achieves the best effect. After the grease injection process is completed, the staff needs to shut down the equipment and clean the equipment to ensure that there is no residual grease on the grease injection table 1, the adjustable grease injection module 10 and the matrix co-rotating bearing rotation module 6 and other components, and clean the related parts to prevent the grease from solidifying or contaminating the equipment. Secondly, check the transmission system of the equipment to confirm that all transmission parts are operating normally and there is no damage.

[0055] Embodiment 2 The grease injection method according to the above-mentioned bearing processing grease injection equipment comprises the following steps: S101: A portion of the rotational power of the pulley drive unit 4 is transmitted to the matrix coaxial bearing rotation module 6 through the bevel gear reversing transmission 3 and drives multiple bearing workpieces to rotate. The grease supplied by the adjustable grease injection module 10 is automatically injected into various parts of the bearing raceway, and the distribution of the grease will be affected by the centrifugal force to ensure that the grease can evenly cover the inside of the bearing.

[0056] S102: During the grease injection process, the lifting and lowering grease pressing module 8 presses the grease into various gaps inside the bearing, and the reciprocating traction module 9 synchronously receives the rotational power from the bevel gear reversing transmission 3 to make the lifting and lowering grease pressing module 8 reciprocate and slide on the top of the bearing workpiece.

[0057] S103: When the pressure difference detected by the pressure sensor 605 is greater than the preset pressure difference value, the adjustable grease injection modules 10 move away from each other, and the amount of grease injected into the bearing gap by the adjustable grease injection modules 10 decreases.

[0058] S104: The pneumatic telescopic rod 908 is started and the output end is extended. The output end of the pneumatic telescopic rod 908 drives the boss 904 to move away from the transmission shaft 901 end, and the swing range of the swing arm 905 increases. The swing arm 905 drives the U-shaped long arm 803 to increase the horizontal reciprocating sliding distance on the top of the bearing through the mountain-shaped arm 7.

[0059] The grease injection method of the bearing processing grease injection equipment has high grease injection efficiency and good grease injection effect.
