Description

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy.

[0003] Insert bearing units are usually high-precision bearing assemblies composed of sealed insert bearings and various types of insert bearing seats. They have good interchangeability and certain self-aligning functions. They can work in different working conditions and mechanical devices. Insert bearing units are also called bearing units. When they are not equipped with bearings, they are called insert bearing seats.

[0004] Traditionally, the processing of outer spherical bearing seats uses a robot in conjunction with a conveyor belt to transfer the bearing seats to each process processing equipment for processing, forming a set of assembly line processing equipment.

Detailed implementation manner

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1-9 , the present invention provides a technical solution: a processing device for an outer spherical bearing seat, including a workbench 1. On both sides of the workbench 1 along its length direction, a drilling assembly 2 and a milling assembly 3 are respectively arranged. A clamping assembly 4 is further arranged on the workbench 1, and the clamping assembly 4 is located between the drilling assembly 2 and the milling assembly 3.

[0036] As Figure 2 , the clamping assembly 4 includes a substrate 5. At the centers of both sides of the substrate 5 along the width direction of the workbench 1, a rotating shaft 6 is fixedly connected. On the side of the rotating shaft 6 away from the substrate 5, a fixing plate 7 is rotatably connected. The fixing plate 7 is fixedly connected to the workbench 1. One of the rotating shafts 6 penetrates through the fixing plate 7 and is fixedly connected to a first driving motor 8, and the first driving motor 8 is fixedly connected to the fixing plate 7;

[0037] The first driving motor 8 is a synchro motor and can achieve a specific angle of rotation. In this embodiment, the first driving motor 8 drives the substrate 5 to rotate at a specific angle of 90 degrees.

[0038] As shown in Figure 4 , grooves 9 are provided at the centers of both sides of the substrate 5 along the thickness direction. Four support blocks 10 are slidably connected to both sides of the substrate 5 along the thickness direction. The four support blocks 10 are evenly distributed in a circle with the center of the groove 9 as the reference. The side of the four support blocks 10 facing away from the substrate 5 is used to support the spherical outer support seat. Therefore, the clamping assembly 4 can clamp two spherical outer bearing seats at the same time for machining.

[0039] As shown in Figure 5 , the four support blocks 10 move relatively with the center of the groove 9 as the base point, approaching or separating from each other. The cross-sectional shape of the side of the support block 10 close to the groove 9 is trapezoidal. Therefore, a slit 11 is formed between adjacent two support blocks 10. The slit 11 is the space reserved for the drill bit 53 when the drilling assembly 2 drills the spherical outer bearing seat, and is used to prevent the drill bit 53 from colliding with the support block 10 or the substrate 5 and causing damage.

[0040] As shown in Figure 4 , two first sliders 12 are fixedly connected to the side of the support block 10 close to the substrate 5. The two first sliders 12 are fixedly connected to both sides of the support block 10 along the length direction. The substrate 5 is provided with a first chute 13 corresponding to the support block 10. The first chute 13 is matched with the first slider 12, and the first chute 13 is communicated with the groove 9;

[0041] A fixing block 14 is arranged on the side of the support block 10 away from the groove 9. The fixing block 14 is fixedly connected to the substrate 5. A first hydraulic telescopic cylinder 15 is arranged on the side of the fixing block 14 close to the support block 10. The fixed end of the first hydraulic telescopic cylinder 15 is fixedly connected to the fixing block 14, and the output end of the first hydraulic telescopic cylinder 15 is fixedly connected to the support block 10, so as to drive the support block 10 to slide along the first chute 13 through the first hydraulic telescopic cylinder 15;

[0042] When the four support blocks 10 move to the limit towards the center side close to the groove 9, the side of the four support blocks 10 facing away from the substrate 5 can support the smallest type of spherical outer bearing seat, and the formed slit 11 meets the requirements for drilling the smallest type of spherical outer bearing seat;

[0043] When the four support blocks 10 move to the limit towards the side away from the center of the groove 9, the side of the four support blocks 10 facing away from the substrate 5 can support the largest type of spherical outer bearing seat, and the formed slit 11 meets the requirements for drilling the largest type of spherical outer bearing seat.

[0044] A push block 16 is slidably connected to the side of each support block 10 facing away from the substrate 5. The push block 16 is arranged at the center of the support block 10 along the length direction. The sliding direction of the push block 16 is the same as that of the support block 10. The push block 16 is used to clamp and fix the spherical outer bearing seat in the radial direction along its central hole;

[0045] On one side of the pushing block 16 close to the supporting block 10, a second slider 17 is fixedly connected. The supporting block 10 is provided with a second sliding groove 18 corresponding to the second slider 17, and the second slider 17 is matched with the second sliding groove 18;

[0046] On one side of the fixing block 14 close to the pushing block 16, a second hydraulic telescopic cylinder 19 is provided. The fixed end of the second hydraulic telescopic cylinder 19 is fixedly connected to the fixing block 14, and the output end of the second hydraulic telescopic cylinder 19 is fixedly connected to the pushing block 16, so as to drive the pushing block 16 to slide through the second hydraulic telescopic cylinder 19;

[0047] On the side of the supporting block 10 facing away from the substrate 5, two third hydraulic telescopic cylinders 52 are provided. The two third hydraulic telescopic cylinders 52 are respectively arranged on both sides of the supporting block 10 along the length direction. The fixed end of the third hydraulic telescopic cylinder 52 is fixedly connected to the supporting block 10, and the output end of the third hydraulic telescopic cylinder 52 is fixedly connected with a pressing block 20, and the pressing block 20 is used for locking and fixing the spherical plain bearing housing along the axial direction of its central hole.

[0048] Such as Figure 5 , at the four corners of the first groove 9, a first electric telescopic rod 21 is fixedly connected. The setting of the first electric telescopic rod 21 does not affect the clamping and processing of the largest type of spherical plain bearing housing by the device;

[0049] Such as Figure 7 , the output end of the first electric telescopic rod 21 is fixedly connected with a first connecting block 22. A second groove 23 is formed in the first connecting block 22. A cylinder 24 is rotatably connected in the second groove 23. A second driving motor 25 is fixedly connected to the first connecting block 22. The output shaft of the second driving motor 25 penetrates through the inner wall of the second groove 23 and is fixedly connected to the cylinder 24 coaxially;

[0050] On the half outer circumferential surface of the cylinder 24 along the radial direction of its axis, a laser scanning sensor 26 is embedded. The output end of the laser scanning sensor 26 is signal-connected to a processor. The laser scanning sensor 26 irradiates a laser on the target object, and receives the reflected light and the changed refracted light through a photosensitive element, so as to perform an overall scan of the outer contour of the spherical plain bearing housing in a non-contact manner;

[0051] On the half outer circumferential surface of the cylinder 24 along the radial direction of its axis and facing away from the laser scanning sensor 26, a first nozzle 27 is embedded;

[0052] The second driving motor 25 is also a synchro motor. Before clamping the spherical plain bearing housing, the cylinder 24 is rotated by the second driving motor 25 to make the laser scanning sensor 26 face the side of the first groove 9, so as to perform information scanning on the outer contour of the spherical plain bearing housing;

[0053] All information about spherical plain bearing housings of all models and specifications and related processing information are pre-stored in the processor. After the laser scanning sensor 26 scans the outer contour of the spherical plain bearing housing, the processor determines the corresponding model and specification of the spherical plain bearing housing, and retrieves the information and processing information of the spherical plain bearing housing of this model and specification, facilitating subsequent clamping and processing of the spherical plain bearing housing.

[0054] When processing the spherical plain bearing housing, the driving motor two 25 rotates the cylinder 24 to make the nozzle one 27 face one side of the groove one 9. At the same time, the driving motor two 25 is controlled to correspond to the spherical plain bearing housing of this model and specification and in combination with the processing progress, and the electric telescopic rod one 21 is coordinated to adjust the height and angle of the coolant sprayed by the nozzle one 27 in real time, thereby improving the processing effect and processing efficiency of the spherical plain bearing housing.

[0055] Such as Figure 5 、 Figure 6 , a cavity 28 is provided in the center of the substrate 5, and two driving motors three 29 are fixedly connected in the cavity 28. The output ends of the two driving motors three 29 are arranged away from each other, and the output shafts of the two driving motors three 29 penetrate through the cavity 28 and are fixedly connected with a sleeve 30;

[0056] One side of the sleeve 30 away from the driving motor three 29 is fixedly connected with an electric telescopic rod two 31. The output end of the electric telescopic rod two 31 is fixedly connected with a connecting block two 32. Two electric telescopic rods three 33 are fixedly connected to the connecting block two 32. The two electric telescopic rods three 33 are arranged away from each other with the center of the connecting block two 32 as the reference. The output end of one of the electric telescopic rods three 33 is fixedly connected with a nozzle two 34, and the output end of the other electric telescopic rod three 33 is fixedly connected with a 3D sensor 35;

[0057] The 3D sensor 35 is signal-connected to the processor. The 3D sensor 35 integrates laser scanning and laser ranging and has both measurement and scanning functions, thereby performing dimensional inspection and roughness inspection on the processed spherical plain bearing housing.

[0058] A liquid-electric slip ring one 36 is arranged on the inner wall of the groove one 9. The liquid-electric slip ring one 36 is sleeved on the output shaft of the driving motor three 29. The liquid-electric slip ring one 36 is a conventional existing technology. As a transfer device for the liquid path transmission of the nozzle two 34 and the signal transmission of the 3D sensor 35, it can enable the rotating nozzle two 34 and 3D sensor 35 to be connected to the pipeline and signal without obstacles respectively.

[0059] The liquid-electric slip ring one 36 includes a rotor coil and a stator coil sleeved outside the rotor coil. The rotor coil is fixedly connected to the output shaft of the driving motor three 29, and the stator coil is fixedly connected to the inner wall of the groove one 9. The output connecting wire and output connecting pipe of the rotor coil of the liquid-electric slip ring one 36 are both arranged in the sleeve 30;

[0060] A liquid-electric slip ring 36 is provided with a housing 37 on the outside. The housing 37 is fixedly connected to the inner wall of the first groove 9. The housing 37 wraps the liquid-electric slip ring 36. The sleeve 30 penetrates through the housing 37 and is rotatably connected to the housing 37 in a sealed manner.

[0061] As Figure 3 , a liquid-electric slip ring 38 is sleeved on the rotating shaft 6. The stator ring of the liquid-electric slip ring 38 is fixedly connected to the fixing plate 7. The rotor ring of the liquid-electric slip ring 38 is fixedly connected to the rotating shaft 6. The liquid-electric slip ring 38 has the same function as the liquid-electric slip ring 36 and is used for unobstructed transfer of various devices with pipeline or wire connections on the clamping assembly 4.

[0062] The input ends of the first nozzle 27 and the second nozzle 34 are both connected to a pump body through pipelines. Control valves are arranged on the pipelines connecting the first nozzle 27 and the second nozzle 34 to the pump body. The input pipeline of the pump body is connected to a liquid storage tank. The liquid storage tank stores coolant. The pump body sprays the coolant outward through the first nozzle 27 and the second nozzle 34 to cool and wash the outer spherical bearing seat during machining of the outer spherical bearing seat, and at the same time wash out the debris on the outer spherical bearing seat;

[0063] The pipeline connecting the input end of the first nozzle 27 to the pump body is transferred through the liquid-electric slip ring 38; the pipeline connecting the input end of the second nozzle 34 to the pump body is transferred through the liquid-electric slip ring 36 and the liquid-electric slip ring 38; the signal line connecting the laser scanning sensor 26 to the processor is transferred through the liquid-electric slip ring 38; the signal line connecting the 3D sensor 35 to the processor is transferred through the liquid-electric slip ring 36 and the liquid-electric slip ring 38.

[0064] As Figure 1 , fixing components 39 are arranged on both sides of the clamping assembly 4 along the width direction of the workbench 1;

[0065] As Figure 8 , the fixing component 39 includes two connecting plates 40. The two connecting plates 40 are symmetrically arranged with the center of the base plate 5 as the reference. The connecting plate 40 is in a "concave" shape. Therefore, the connecting plate 40 is provided with a notch 41. The notches 41 of the two connecting plates 40 are arranged opposite to each other;

[0066] Four fourth hydraulic telescopic cylinders 42 are arranged in the notch 41 of each connecting plate 40. The four fourth hydraulic telescopic cylinders 42 are divided into two groups and are respectively arranged on both sides of the connecting plate 40 along the height direction. The two fourth hydraulic telescopic cylinders 42 in the same group are arranged opposite to each other with the central axis of the rotating shaft 6 as the reference. The fixed ends of the two fourth hydraulic telescopic cylinders 42 are fixedly connected to the inner wall of the notch 41. The output ends of the two fourth hydraulic telescopic cylinders 42 are fixedly connected with a top block 43. The top block 43 is correspondingly located at the angular joint of the base plate 5 when it is perpendicular to the workbench 1;

[0067] When the substrate 5 rotates to a state perpendicular to the workbench 1, the output end of the hydraulic telescopic cylinder four 42 is extended to clamp and fix the substrate 5 with the top block 43, improving the stability when the drilling assembly 2 and the milling assembly 3 process the outer spherical bearing seat on the substrate 5.

[0068] The rotating shaft 6 penetrates through the connecting plate 40 and is slidably connected to the connecting plate 40. One side of the connecting plate 40 close to the workbench 1 is slidably connected to the workbench 1;

[0069] On both sides of the connecting plate 40 close to the workbench 1 along the width direction, sliding blocks three 44 are fixedly connected. The workbench 1 is provided with sliding grooves three 45 corresponding to the sliding blocks three 44. The sliding blocks three 44 are matched with the sliding grooves three 45. At the four corners of one side of the connecting plate 40 close to the workboard, hydraulic telescopic cylinders five 46 are arranged. The fixed ends of the hydraulic telescopic cylinders five 46 are fixedly connected to the fixing plate 7, and the output ends of the hydraulic telescopic cylinders five 46 are fixedly connected to the connecting plate 40, thereby driving the connecting plate 40 to slide through the hydraulic telescopic cylinders five 46;

[0070] When the substrate 5 rotates from the vertical state, the output end of the hydraulic telescopic cylinder four 42 is retracted, and the top block 43 does not contact the substrate 5. Then, the output end of the hydraulic telescopic cylinder five 46 is retracted to prevent the substrate 5 from colliding with the fixing assembly 39 during rotation.

[0071] Below the clamping assembly 4 on the workbench 1, a groove three 47 is provided. A filter screen is clamped in the groove three 47. The groove three 47 is connected to a coolant filter through a pipeline. The coolant filter is connected to a liquid storage tank. The coolant filter is an existing conventional technology and is used to separate and filter the coolant and the debris in the coolant.

[0072] The debris generated during the processing is preliminarily filtered by the filter screen, and then the debris in the coolant is further separated by the coolant filter. Finally, the filtered coolant enters the liquid storage tank for reuse.

[0073] Such as Figure 9 , the drilling assembly 2 includes a three-axis linear motor group one 48. The three-axis linear motor group one 48 is an existing conventional technology. A driving motor four 49 is fixedly connected to the output end of the three-axis linear motor group one 48. A drill bit 53 is fixedly connected to the output end of the driving motor four 49.

[0074] The milling assembly 3 includes a three-axis linear motor group two 50. The three-axis linear motor group two 50 is an existing conventional technology. A driving motor five 51 is fixedly connected to the output end of the three-axis linear motor group two 50. A milling cutter 54 is fixedly connected to the output end of the driving motor five 51.

[0075] In this embodiment, in the initial state, the substrate 5 is in a horizontal state, and the support block 10 is located at the limit position on one side close to the center of the first groove 9. After the outer spherical bearing seat to be processed is clamped by a manipulator and centered with the center of the first groove 9, it is placed on the support block 10.

[0076] Before the placement is completed, the cylinder 24 is rotated by the second driving motor 25 to make the laser scanning sensor 26 face the center side of the first groove 9, so as to scan the information of the outer contour of the outer spherical bearing seat and determine the model specification of the outer spherical bearing seat.

[0077] The information of all model specifications of the outer spherical bearing seats and related processing information are pre-stored in the processor. After the outer contour of the outer spherical bearing seat is scanned by the laser scanning sensor 26, the processor determines the corresponding model specification of the outer spherical bearing seat and retrieves the information and processing information of the outer spherical bearing seat of this model specification.

[0078] The processor establishes a three-dimensional model based on the actual overall contour of the scanned outer spherical bearing seat and compares it with the pre-stored three-dimensional model information to ensure that the coincidence degree of the three-dimensional model of the outer spherical bearing seat and the pre-stored three-dimensional model is within the processing requirements.

[0079] At the same time, the output end of the second electric telescopic rod 31 corresponding to the 3D sensor 35 is controlled to extend by a corresponding length to be close to the inner wall of the central hole of the outer spherical bearing seat; the 3D sensor 35 is driven to rotate in a circle by the third driving motor 29 to ensure that the central hole of the outer spherical surface is coaxially arranged with the sleeve 30, so as to ensure the coaxiality of the central hole of the outer spherical bearing seat.

[0080] For the outer spherical bearing seats with the coincidence degree not meeting the requirements or the coaxiality not meeting the requirements, they are replaced to prevent deviations during the processing, resulting in the unusability of the processed outer spherical bearing seats.

[0081] After the detection is completed, the output end of the first hydraulic telescopic cylinder 15 is controlled to drive the support block 10 to move, so that the position where the support block 10 is located can support the outer spherical bearing seat with the largest area, and the space of the strip opening 11 formed by the position where the support block 10 is located meets the drilling requirements.

[0082] After the outer spherical bearing seat is placed on the support block 10, the output end of the second hydraulic telescopic cylinder 19 is controlled to extend, so that the push block 16 clamps and fixes the outer spherical bearing seat in the radial direction of its central hole.

[0083] At the same time, the output end of the third hydraulic telescopic cylinder 52 is controlled to retract, so that the pressing block 20 presses and fixes the outer spherical bearing seat in the axial direction of its central hole, so as to completely fix the outer spherical bearing seat.

[0084] After the fixation is completed, start the first driving motor 8 to rotate the substrate 5 by 90 degrees towards the milling component 3. Then, control the output end of the fifth hydraulic telescopic cylinder 46 on the fixing component 39 to extend, so that the connecting plates 40 approach each other. Subsequently, control the output end of the fourth hydraulic telescopic cylinder 42 to extend, so that the top block 43 clamps and fixes the substrate 5, improving the stability of the substrate 5 during the processing and enhancing the processing accuracy.

[0085] Then, control the movement of the output end of the three-axis linear motor group two 50 of the milling component 3, so that the fifth driving motor 51 rotates around the axis of the central hole of the spherical outer bearing seat. The rotation diameter is smaller than the inner diameter of the central hole, and the milling cutter 54 of the fifth driving motor 51 can mill the inner wall of the central hole, thus completing the milling work of the spherical outer bearing seat.

[0086] During the milling process, control the output end of the second electric telescopic rod 31 to extend by a corresponding length, and by controlling the output end of the third electric telescopic rod 33 corresponding to the second nozzle 34 to extend by a corresponding length, make the second nozzle 34 approach the inner wall of the spherical outer bearing seat. Then, in cooperation with the rotation of the third driving motor 29, make the second nozzle 34 follow the milling cutter 54 for cooling and flushing.

[0087] At the same time, the 3D sensor 35 rotates circumferentially following the third driving motor 29, and performs dimensional detection and roughness detection on the milled surface of the central hole through the 3D sensor 35.

[0088] During the milling process, perform dimensional detection on the milled surface through the 3D sensor 35 to prevent the occurrence of over-milling or under-milling.

[0089] At the same time during the milling process, detect the roughness of the milled surface through the 3D sensor 35 to see if it meets the requirements. If it does not meet the requirements, it means that the milling cutter 54 is excessively worn, and the milling cutter 54 needs to be replaced. Stop the operation of the milling component 3 and perform a reset, replace the milling cutter 54 and then continue the milling.

[0090] After the milling is completed, perform a secondary circumferential rotation scan on the central hole of the spherical outer bearing seat through the 3D sensor 35 to ensure that the size of the central hole after milling meets the requirements and the coaxiality meets the requirements.

[0091] When it is detected that the coaxiality of the central hole of the spherical outer bearing seat is deviated, it indicates that there is a problem with the clamping component 4, and notify the staff to conduct relevant inspections and adjustments.

[0092] After the milling is completed, control the output end of the fourth hydraulic telescopic cylinder 42 to retract, so that the top block 43 does not contact the substrate 5. Then, control the output end of the fifth hydraulic telescopic cylinder 46 to retract to prevent the substrate 5 from colliding with the fixing component 39 when rotating.

[0093] Control the driving motor 1 to rotate, so that the substrate 5 rotates 90 degrees again along the previous rotation direction, making the side of the substrate 5 without the clamped spherical outer bearing housing face horizontally upward, and clamp and place the spherical outer bearing housing to be processed on the support block 10 through the manipulator. This process is the same as the operation process of placing the first spherical outer bearing housing, and will not be repeated here.

[0094] After the second spherical outer bearing housing is placed, control the driving motor 1 to run again, so that the substrate 5 rotates 90 degrees again along the previous rotation direction, so that the second spherical outer bearing housing faces the milling component 3 side, and the first spherical outer bearing housing faces the drilling component 2 side;

[0095] Then control the output end of the fifth hydraulic telescopic cylinder 46 on the fixing component 39 to extend again, so that the connecting plates 40 approach each other, and then control the output end of the fourth hydraulic telescopic cylinder 42 to extend, so that the top block 43 clamps and fixes the substrate 5, improving the stability of the substrate 5 during the processing and improving the processing accuracy;

[0096] At the same time, start the drilling component 2 and the milling component 3 to perform machining on the first spherical outer bearing housing and the second spherical outer bearing housing respectively;

[0097] The milling process of the second spherical outer bearing housing is the same as the operation process of the first milling process. The specific processing data of the second spherical outer bearing housing is adjusted accordingly according to the relevant model specifications of the spherical outer bearing housing;

[0098] When drilling the first spherical outer bearing housing, the processor controls the relevant program for processing the spherical outer bearing housing of this model specification to run on the drilling component 2, controls the output end of the first three-axis linear motor group 48 to move, so that the drill bit 53 on the driving motor 4 approaches the position to be drilled, and starts drilling;

[0099] During the drilling process, rotate the cylinder 24 by the driving motor 2, so that the first nozzle 27 faces the drilling position, and cooperate with the first electric telescopic rod 21 to adjust the spraying distance and spraying angle of the first nozzle 27. The pump body sprays coolant onto the spherical outer bearing housing through the first nozzle 27 to cool and wash the drill bit 53.

[0100] After drilling is completed, control the drilling component 2 to move back to its original position, scan the spherical outer bearing housing again through the laser scanning sensor 26, and the processor re-establishes a three-dimensional model of the scanned contour information of the spherical outer bearing housing and compares it with the corresponding three-dimensional model stored in advance to detect whether the processing information of the drilling meets the requirements. The processing information includes: position, hole diameter, etc.

[0101] If the processing information of the drilling does not meet the processing requirements, it indicates that there is a problem with the drill bit 53 of the drilling assembly 2. Notify the staff to check and adjust the state of the drill bit 53 of the drilling assembly 2, and recycle the spherical plain bearing housing.

[0102] Control the first driving motor 8 to run again, so that the substrate 5 rotates 90 degrees again in the previous rotation direction, so that the first spherical plain bearing housing is horizontally upward and the second spherical plain bearing housing is horizontally downward;

[0103] After the inspection of the first spherical plain bearing housing is completed, control the output end of the third hydraulic telescopic cylinder 52 to extend, control the output end of the second hydraulic telescopic cylinder 19 to retract, then take it out by the manipulator, place the qualified spherical plain bearing housing on the next process, place the unqualified spherical plain bearing housing at the recycling place for recycling, and clamp a spherical plain bearing housing to be processed for clamping, so as to carry out continuous processing.
