When the milling cutter in the milling assembly contacts the end face of the bearing seat, the buffer spring provides initial buffering due to its own elastic deformation, thereby reducing the impact force between the milling cutter and the bearing seat; as the milling process proceeds, the non-Newtonian fluid changes its viscosity and hardness according to the change in milling force, further adjusting the contact pressure and fit between the milling cutter and the surface of the bearing seat, thereby ensuring the milling accuracy and stability; the rubber buffer body, with its good elasticity and wear resistance, assists in buffering and maintains the stability of the overall structure between the milling assembly and the flexible connector.

[0029] The entire milling process, from feeding, clamping, milling to unloading, most operations can be completed through the automatic control system.

[0030] The milling device of the present invention has a reasonable structural design, significant rationality and innovation, and realizes efficient double-sided milling function through a clever mechanical structure layout. Specifically, the milling device organically integrates core components such as a base, a workbench, a spindle, a clamping mechanism, a feeding mechanism, a milling mechanism, and a driving mechanism to form a compact and fully functional processing system. Compared with the traditional multi-station or multi-device collaborative processing method, the present invention significantly reduces the footprint of the equipment, simplifies the equipment structure, saves installation space, and reduces the difficulty of installation and debugging of the equipment. At the same time, the simple structure also reduces maintenance costs and equipment failure rates, and improves the reliability and service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] A double-sided milling device and a processing method for a bearing seat provided by the present invention are now described.

[0054] like Figures 1 to 9 As shown, a double-sided milling device for machining a bearing seat provided in a first embodiment of the present invention includes a base 10, a worktable 20, a spindle 11, a feeding mechanism 40, a clamping mechanism 30 and a milling mechanism 50;

[0055] The workbench 20 is arranged parallel to the base 10 and connected to the rotating shaft of the base 10; the spindle 11 is vertically installed in the center of the base 10, and the upper end of the spindle 11 passes through the workbench 20 and is provided with a clamping mechanism 30 for clamping the bearing seat; the feeding mechanism 40 is arranged on the workbench 20 on one side of the spindle 11, and is used to transport the bearing seat to be processed to the material taking position for the clamping mechanism 30 to clamp; the milling mechanism 50 is arranged on the workbench 20 on the other side of the spindle 11, and is used to perform double-sided milling processing on the bearing seat located on the clamping mechanism 30; the driving mechanism 60 is arranged on the base 10, and is used to drive the workbench 20 to drive the milling mechanism 50 to rotate into the milling position on the one hand, and drive the spindle 11 to drive the clamping mechanism 30 to rotate to clamp the bearing seat and then return to the milling position;

[0056] Among them, the milling mechanism 50 includes a mounting seat 51, a translation component 70, a flexible connector 52, a milling component 53 and an adjustment component 54; the mounting seat 51 is arranged on the workbench 20, and its top end is higher than the upper surface of the workbench 20, and the mounting seat 51 moves in and out of the workbench 20 along the radial direction of the spindle 11 under the action of the translation component 70; two milling components 53 arranged opposite to each other up and down are arranged at the top end of the mounting seat 51, and are used for double-sided milling of the bearing seat; the adjustment component 54 is connected to the two milling components 53 through two flexible connectors 52, and is used to drive the two milling components 53 to move closer to or away from each other in the vertical direction; wherein, the flexible connector 52 is used to provide buffering when the milling component 53 contacts the end face of the bearing seat, and to adjust the contact relationship between the milling component 53 and the surface of the bearing seat during the milling process.

[0057] It should be noted that the base 10 includes a base plate 101 and a fixed rod 102, the fixed rod 102 is vertically fixed at the center of the base plate 101, the main shaft 11 is sleeved on the outside of the fixed rod 102, and, under the action of the driving mechanism 60, rotates around the axis of the fixed rod 102, the milling assembly 53 includes a servo motor 531 and a milling cutter 532, the milling cutter 532 is installed at the output end of the servo motor 531, in order to make the workbench 20 rotate more smoothly, two support rods are arranged on the lower side of the workbench 20, and the lower end of the support rod is installed with a ball, the ball is rollingly connected with the limiting groove arranged on the upper surface of the base plate 101, the limiting groove is circular, and the limiting groove is coaxially arranged with the fixed rod 102, this part of the content is the prior art, and no more introduction is given here.

[0058] During processing, the bearing seat to be processed is placed on a specially set feeding mechanism 40, and the feeding mechanism 40 is set on the workbench 20 on one side of the main shaft 11, and is used to transport the bearing seat to be processed stacked in the feeding mechanism 40 to the material picking position for clamping mechanism 30 to clamp. The position of the feeding mechanism 40 ensures that the operator can place the bearing seat conveniently and quickly, and prepare for subsequent clamping operations. The feeding mechanism 40 transports the bearing seat at the bottom to the material taking position, and starts the driving mechanism 60. The driving mechanism 60 is arranged on the bottom plate 101, and is used to drive the workbench 20 to rotate on the one hand, thereby driving the milling mechanism 50 to rotate and enter the milling position, and on the other hand, drives the spindle 11 to rotate, thereby driving the clamping mechanism 30 to rotate and clamp the bearing seat and then return to the milling position. Specifically, the driving mechanism 60 drives the clamping mechanism 30 to rotate through the spindle 11. When the clamping mechanism 30 rotates to the material taking position, the driving mechanism 60 stops working, the spindle 11 and the clamping mechanism 30 thereon stop rotating, and the clamping mechanism 30 is started. The clamping mechanism 30 stably clamps the bearing seat, and the clamping force of the clamping mechanism 30 on the bearing seat is moderate, so that the bearing seat will not be displaced during the processing due to too small a clamping force, nor will the bearing seat be damaged due to too large a clamping force.

[0059] It should be made clear here that the clamping mechanism 30 has two positions, the first position is the milling position, which is also the clamping position when the bearing seat is milled, and the second position is the material taking position for clamping the bearing seat from the feeding mechanism 40; when the clamping mechanism 30 is in the milling position (i.e. the clamping position), and the bearing seat to be milled is clamped on the clamping mechanism 30, the driving mechanism 60 is started, and the driving mechanism 60 drives the workbench 20 and the milling mechanism 50 thereon to rotate, and when the milling mechanism 50 rotates to the milling position, it stops, and at the same time, the translation assembly 70 is turned on, and the translation assembly 70 drives the mounting seat 51 to move along the radial direction of the spindle 11 until the milling mechanism 50 is adjusted to a suitable processing position, and the operation of the translation assembly 70 is stopped to prepare for subsequent milling processing, and the suitable processing position is when the clamping mechanism 30 is in the milling position, The milling mechanism 50 has a corresponding processing position. Here, the translation component 70 can be a mechanism composed of a hydraulic cylinder 71 and a slide rail 72, which can drive the mounting seat 51 to translate, or it can be a mechanism that only drives the mounting seat 51 to translate by a rodless cylinder. Then, the adjustment component 54 in the mounting seat 51 starts to work. Through the action of the adjustment component 54, the two milling components 53 approach each other in the vertical direction, and the milling cutter 532 in the milling component 53 gradually contacts the upper and lower end surfaces of the bearing seat. The servo motor 531 is started, and the servo motor 531 drives the milling cutter 532 set at its output end to rotate, and double-sided milling is performed on the two end surfaces of the bearing seat. The flexible connector 52 provides a buffer when the milling cutter 532 contacts the end surface of the bearing seat, and adjusts the contact relationship between the milling cutter 532 and the surface of the bearing seat during the milling process to ensure processing accuracy. After the milling is completed, the rotation of the milling cutter 532 is stopped, and the adjustment component 54 is started again to make the two milling cutters 532 move away from each other, and then the milling mechanism 50 is rotated in the opposite direction to the initial position, the clamping mechanism 30 is released, and the bearing seat is discharged through the feeding channel 80.

[0060] like Figure 2 As shown, a first groove is provided on the upper surface of the workbench 20, and two slide rails 72 are provided in parallel in the first groove. The length direction of the slide rail 72 is parallel to the radial direction of the main shaft 11. The hydraulic cylinder 71 is provided at the bottom of the first groove, and the piston rod end of the hydraulic cylinder 71 is connected to the bottom of the mounting seat 51. The piston rod of the hydraulic cylinder 71 pushes the mounting seat 51 to move along the slide rail 72, and the milling mechanism 50 is adjusted to a suitable processing position to prepare for subsequent milling processing.

[0061] Compared with the prior art, the double-sided milling device provided in this embodiment for bearing seat processing ensures the contact relationship between the milling cutter 532 and the surface of the bearing seat through the cooperation of the flexible connecting piece 52 and the adjustment assembly 54, thereby improving the processing accuracy; and the double-sided milling device can perform double-sided processing at the same time, significantly improving the processing efficiency.

[0062] The milling device of the present invention has a reasonable structural design, significant rationality and innovation, and realizes efficient double-sided milling function through a clever mechanical structure layout. Specifically, the milling device organically integrates core components such as the base 10, the worktable 20, the spindle 11, the clamping mechanism 30, the feeding mechanism 40, the milling mechanism 50 and the driving mechanism 60 to form a compact and fully functional processing system. Compared with the traditional multi-station or multi-device collaborative processing method, the present invention significantly reduces the footprint of the equipment, simplifies the equipment structure, saves installation space, and reduces the difficulty of installation and debugging of the equipment. At the same time, the simple structure also reduces maintenance costs and equipment failure rates, and improves the reliability and service life of the equipment.

[0063] like Figures 2 to 3 As shown, a specific embodiment provided by the present invention on the basis of the first embodiment is as follows: the flexible connecting member 52 includes a connecting shell 521, a buffer spring 526, a rubber buffer body 527 and an elastic spacer 522. The connecting shell 521 is arranged on one side of the adjusting component 54. Two elastic spacers 522 are arranged in parallel up and down inside the connecting shell 521. The two elastic spacers 522 respectively divide the connecting shell 521 into a buffer chamber 523, a damping chamber 524 and an adjusting chamber 525. A buffer spring 526 is vertically arranged in the buffer chamber 523. The upper end of the buffer spring 526 is fixed to the inner wall of the connecting shell 521, and the lower end is connected to the elastic spacer 522. The damping chamber 524 is filled with a non-Newtonian fluid 528; and a rubber buffer body 527 is arranged in the adjusting chamber 525.

[0064] The buffer spring 526, non-Newtonian fluid 528 and rubber buffer body 527 inside the flexible connector 52 work together. When the milling cutter 532 contacts the end face of the bearing seat, the buffer spring 526 provides initial buffering due to its own elastic deformation, reduces the impact force, and protects the milling cutter 532 and the bearing seat. The non-Newtonian fluid 528 adopts a shear-liquefied non-Newtonian fluid, that is, it is solid in the normal working state, and has liquid properties after being subjected to an impact or vibration exceeding the threshold. During the milling process, the non-Newtonian fluid 528 has unique rheological properties, and changes viscosity and hardness according to the force conditions. When the milling force changes, the non-Newtonian fluid 528 can adjust its own state in time, further adjust the contact pressure and fit between the milling cutter 532 and the surface of the bearing seat, and ensure milling accuracy. And when the milling cutter 532 is subjected to a strong impact, it can quickly liquefy and deform, thereby providing buffering and protection for the milling cutter 532. The rubber buffer body 527, with its good elasticity and wear resistance, assists in buffering and maintains the overall structural stability of the connector.

[0065] The unique design of the flexible connector 52 enables it to automatically adjust the contact relationship between the milling cutter 532 and the bearing seat surface according to the force conditions during the milling process. During the milling process, the milling force will change with the changes in the processing conditions. It is difficult for traditional milling devices to make timely and effective adjustments to such changes, which easily leads to processing quality problems. The flexible connector 52 in the present invention can be adjusted in time according to the changes in the milling force, effectively avoiding the processing quality problems caused by uneven milling force, and further improving the processing accuracy and surface quality.

[0066] The buffering and adjustment function of the flexible connector 52 effectively reduces the position deviation of the bearing seat during the processing, ensures the parallelism and dimensional accuracy of the upper and lower end surfaces, and meets the requirements of high-precision processing. The flexible connector 52 automatically adjusts the contact relationship between the milling cutter 532 and the surface of the bearing seat during the milling process to ensure the processing accuracy of the bearing seat. The milling cutter 532 in the milling assembly 53 gradually contacts the upper and lower end surfaces of the bearing seat under the action of the adjustment assembly 54. During the milling process, the flexible connector 52 plays a key role. When the milling cutter 532 contacts the end surface of the bearing seat, the buffer spring 526 first provides initial buffering to reduce the impact force between the milling cutter 532 and the bearing seat; as the milling proceeds, the non-Newtonian fluid 528 changes its viscosity and hardness according to the change of the milling force, further adjusts the contact pressure and fit between the milling cutter 532 and the surface of the bearing seat, and ensures the accuracy and stability of the milling; the rubber buffer body 527 assists in buffering and maintains the stability of the overall structure between the milling assembly 53 and the flexible connector 52.

[0067] The rubber buffer body 527 may be a rubber block having a size and shape matching that of the adjustment cavity 525 .

[0068] In another embodiment, a cavity is provided in the rubber buffer body 527 and is connected to the rubber buffer body 527 through an external air duct. The internal pressure of the rubber buffer body 527 is adjusted by an air filling and deflation device, thereby adjusting the pressure on the non-Newtonian fluid 528 to accurately control the flexible connector 52.

[0069] like Figure 4As shown, the clamping mechanism 30 includes a fixed frame 31, a guide block 32, a first cylinder 33, a clamping claw 34, a connecting rod 35 and a first connecting rod 37. The fixed frame 31 is a frame-type structure, which is arranged in parallel above the workbench 20 and is located at the top of the spindle 11; the two guide blocks 32 are installed at both ends of the fixed frame 31 and are symmetrically arranged, the first cylinder 33 is installed inside the fixed frame 31, and the piston rod end of the first cylinder 33 is slidably connected to and penetrates one side of the fixed frame 31; the two clamping claws 34 are respectively arranged on both sides of the first cylinder 33, and the clamping end of the clamping claw 34 is provided with a V-shaped groove 36 for clamping the bearing seat. In order to better clamp the bearing seat V-shaped groove The inner surface of 36 is provided with anti-slip textures, and the guide end of the clamping jaw 34 is provided with a connecting rod 35, which is slidably connected to and penetrates the guide block 32; two first connecting rods 37 are respectively arranged on both sides of the first cylinder 33, one end of the first connecting rod 37 is connected to the end shaft of the piston rod of the first cylinder 33, and the other end is connected to the middle shaft of the connecting rod 35; wherein, when the first cylinder 33 drives the piston rod to move, the clamping jaw 34 is driven to move through the first connecting rod 37 and the connecting rod 35 to realize the opening and closing of the clamping jaw 34.

[0070] The material clamping mechanism 30 provided in the present invention has a simple structure, is easy to operate, and can realize the stable opening and closing of the clamping jaws 34, ensuring the stability and reliability of the bearing seat clamping. When clamping, the first cylinder 33 is started, and the piston rod of the first cylinder 33 drives the connecting rod 35 to move through the first connecting rod 37, and the connecting rod 35 moves smoothly under the guidance of the guide block 32, driving the clamping jaws 34 to open and close, and the clamping end of the clamping jaws 34 is provided with a V-shaped groove 36, and the V-shaped groove 36 can stably clamp the bearing seat, ensuring that the bearing seat does not move or deform during the processing. After the processing is completed, the first cylinder 33 is reversely started to drive the piston rod to move, drive the clamping jaws 34 to open, and take away the processed bearing seat.

[0071] The fixing frame 31 is made of high-strength steel to ensure the overall strength and stability of the clamping mechanism 30. The guide block 32 is made of wear-resistant material to extend the service life. The first cylinder 33 is a double-acting cylinder to ensure the rapid response and stable operation of the opening and closing of the clamping jaws 34. The V-shaped groove 36 set at the clamping end of the clamping jaws 34 can evenly distribute the clamping force and ensure the stability of the workpiece clamping.

[0072] In a specific embodiment, Figure 6 As shown, the driving mechanism 60 includes a first worm wheel 61, a first worm 62, a first motor 63, a second worm wheel 64, a second worm 65 and a second motor 66. The first worm wheel 61 is sleeved on the lower end of the main shaft 11 and meshes with the first worm 62 arranged on one side thereof, and the first worm 62 is driven to rotate by the first motor 63; the second worm wheel 64 is sleeved on the rotating shaft below the center of the workbench 20 and meshes with the second worm 65 arranged on one side thereof, and the second worm 65 is driven to rotate by the second motor 66.

[0073] When the bearing seat needs to be clamped, the main shaft 11 needs to rotate. At this time, the first motor 63 installed on the base 10 is started, and the first motor 63 operates to output power to drive the first worm 62 connected thereto to rotate. Since the first worm 62 and the first worm wheel 61 are meshed with each other, the first worm wheel 61 starts to rotate under the drive of the first worm 62, thereby driving the main shaft 11 to rotate. Since the main shaft 11 is sleeved on the outside of the fixed rod 102, the main shaft 11 can rotate around the axis direction of the fixed rod 102.

[0074] When milling processing is required, the workbench 20 needs to rotate. At this time, the second motor 66 installed on the base 10 is started, and the output end of the second motor 66 drives the second worm 65 connected thereto to rotate. Since the second worm 65 is meshed with the second worm wheel 64, when the second worm 65 rotates, it will drive the second worm 65 to rotate. Because the second worm wheel 64 is installed on the rotating shaft below the workbench 20, when the second worm wheel 64 rotates, it will drive the milling mechanism 50 on the workbench 20 to rotate. It should be clarified that after the lower end of the main shaft 11 passes through the lower end of the rotating shaft, it is sleeved on the fixed rod 102. The main shaft 11 can rotate alone around the axis of the fixed rod 102. The rotating shaft is sleeved on the outside of the main shaft 11, and the lower end of the rotating shaft is higher than the lower end of the main shaft 11. This can effectively avoid the interference problem faced by the installation of the first worm wheel 61 and the second worm 65.

[0075] Compared with the prior art, the worm gear transmission has a larger transmission ratio, which can convert the high-speed rotation of the motor into a relatively low-speed but more precise rotation of the spindle 11 and the worktable 20, meeting the high precision requirements of the clamping mechanism 30 for adjusting the position of the bearing seat and the milling mechanism 50 when entering the milling position. During the processing, the rotation angle can be precisely controlled to ensure that the processing position of the bearing seat is accurate, greatly improving the processing accuracy.

[0076] like Figure 8 As shown, a slide groove is vertically arranged at the top of the mounting seat 51, and an adjustment assembly 54 is arranged in the slide groove. The adjustment assembly 54 includes a fixed block 541, a screw 542, a third motor 543 and an optical axis 544. The screw 542 is vertically arranged in the slide groove, and the screw 542 is threadedly connected to and penetrates the fixed block 541, and the screw 542 can rotate under the drive of the third motor 543; the optical axis 544 is arranged parallel to the screw 542, and is slidably connected to and penetrates the fixed block 541.

[0077] In actual processing operation, when the positions of the two milling components 53 in the milling mechanism 50 need to be adjusted, the adjustment component 54 starts to function, the third motor 543 is started, and the output end of the third motor 543 drives the screw 542 to rotate in the slide slot. Since the screw 542 and the fixed block 541 are threadedly connected, the rotation of the screw 542 drives the fixed block 541 to move along the axial direction of the screw 542. At the same time, the optical axis 544 arranged parallel to the screw 542 plays a guiding and stabilizing role. The fixed block 541 is slidably connected and penetrates the optical axis 544, so that the fixed block 541 always maintains stable linear motion during the movement process, and will not be offset or shaken due to the rotation of the screw 542. In this way, by driving the screw 542 to rotate by the third motor 543, the two fixed blocks 541 can be accurately controlled to approach or move away from each other in the vertical direction, thereby realizing the adjustment of the position of the milling cutter 532. Compared with the prior art, the adjustment component 54 has a simple and compact structure and high adjustment accuracy, and can quickly and accurately adjust the position of the fixed block 541, thereby effectively improving the processing efficiency.

[0078] like Figures 1 to 7 As shown, the feeding mechanism 40 includes a stacking frame 41, a blocking rod 42, a feeding plate 43, a second cylinder 45, a gear 46, a rack 47, a first guide rail 48 and an ejection member 49. The stacking frame 41 is arranged on the other side of the main shaft 11, and four blocking rods 42 are arranged on the top of the stacking frame 41, and the bearing seats are stacked in the area enclosed by the blocking rods 42; the feeding plate 43 is arranged below the stacking frame 41, and a storage groove 44 is provided on the upper surface of the feeding plate 43 on the side close to the clamping mechanism 30, and a discharge port adapted to the storage groove 44 is provided at the bottom of the stacking frame 41, so that the bearing seats stacked in the stacking frame 41 can fall into the storage groove 44 through the discharge port; the second cylinder 45 is arranged below the feeding plate 43, and the end of its piston rod is rotatably connected to a gear 46, and the upper and lower sides of the gear 46 are respectively provided with racks 47 meshing with it, and one of the gears The rack 47 is fixedly connected to the lower surface of the feed plate 43, and the other rack 47 is fixedly connected to the upper surface of the workbench 20; the first guide rail 48 is arranged in parallel with the second cylinder 45, and the lower surface of the feed plate 43 is slidably connected and adapted to the first guide rail 48; when the second cylinder 45 is extended or retracted, the feed plate 43 is driven to move along the first guide rail 48 through the transmission cooperation of the gear 46 and the two racks 47, and the bearing seat located in the storage groove 44 is transported to a position close to the clamping mechanism 30; the ejection member 49 is arranged at the bottom of the storage groove 44, and when the feed plate 43 transports the bearing seat out of the stacking rack 41, the ejection member 49 ejects a part of the bearing seat out of the storage groove 44.

[0079] Before milling, the operator first stacks the bearing seats to be processed in sequence in the area surrounded by four blocking rods 42 at the top of the stacking rack 41. The height and spacing of the blocking rods 42 are reasonably set, which can not only prevent the bearing seats from tipping over and sliding during stacking, but also facilitate the smooth discharge of the bearing seats on the bottom layer.

[0080] After the preparations are completed, the feeding process is officially started, and the second cylinder 45 starts to work. When the piston rod of the second cylinder 45 extends, the gear 46 connected to the end of the piston rod moves accordingly. Since the upper and lower sides of the gear 46 are respectively meshed with two racks 47, the rack 47 fixedly connected to the lower surface of the feeding plate 43 will drive the feeding plate 43 to move forward along the first guide rail 48 as the gear 46 rotates. The first guide rail 48 provides a precise guide for the movement of the feeding plate 43, ensuring that the feeding plate 43 can move stably in a straight line.

[0081] As the feeding plate 43 moves, the discharge port at the bottom of the stacking frame 41 gradually aligns with the storage slot 44 on the feeding plate 43. At this time, the bearing seat stacked on the bottom layer of the stacking frame 41 accurately falls into the storage slot 44 through the discharge port under the action of gravity. The feeding plate 43 continues to move forward and transports the storage slot 44 carrying the bearing seat to a position close to the clamping mechanism 30. When the upper end of the storage slot 44 is completely separated from the bottom of the stacking frame 41 during the movement of the feeding plate 43, the ejection member 49 arranged at the bottom of the storage slot 44 begins to play a role, and the ejection member 49 ejects a part of the bearing seat out of the storage slot 44, which facilitates the clamping mechanism 30 to clamp.

[0082] Compared with the traditional feeding method, the feeding mechanism 40 utilizes the gear 46 rack 47 transmission and the cylinder to realize the automation of the feeding process, eliminating the need for frequent manual handling and placement of the bearing seat, greatly improving the production efficiency. In addition, compared with the use of the second cylinder 45 alone to push the feeding plate 43 to move, by adding the design of the gear 46 rack 47, the travel of the feeding plate 43 can be increased without expanding the space, thus achieving multiple goals at one stroke.

[0083] like Figures 1 to 7As shown, a feeding channel 80 is provided on the workbench 20 below the clamp 34, and the feeding channel 80 includes a first channel 81, a second channel 82 and a transition slope 83. The first channel 81 is horizontally arranged, and the upper surface is open, and is used to receive the bearing seat dropped from the clamp 34; the second channel 82 is vertically arranged, connected with the first channel 81, and is used to transform the bearing seat from a horizontal state to a vertical state, and the bottom of the second channel 82 is inclined toward the outside of the workbench 20; the transition slope 83 is inclinedly arranged between the first channel 81 and the second channel 82, and is used to guide the bearing seat from the first channel 81 to enter the second channel 82; when the clamp 34 releases the bearing seat, the bearing seat falls into the first channel 81, and enters the second channel 82 through the transition slope 83, and the bearing seat is transformed from a horizontal state to a vertical state, and slowly rolls out of the workbench 20 along the inclined bottom of the second channel 82.

[0084] In the actual processing, after the bearing seat is clamped by the clamping mechanism 30 and the double-sided milling is completed, the material unloading process begins, and at this time, the feeding channel 80 begins to play a role. The workbench 20 below the clamping jaws 34 is provided with a feeding channel 80, which is composed of a first channel 81, a second channel 82 and a transition slope 83. When the clamping jaws 34 of the clamping mechanism 30 release the bearing seat, due to the action of gravity, the bearing seat will fall vertically and accurately fall into the first channel 81 which is horizontally arranged and has an open upper surface. The design of the first channel 81 can effectively receive the bearing seat that falls from the clamping jaws 34, ensuring that it smoothly enters the feeding channel 80.

[0085] After the bearing seat enters the first channel 81, it continues to move forward relying on its own gravity and inertia. When it reaches the connection between the first channel 81 and the second channel 82, the transition slope 83 plays a key role. The transition slope 83 is set between the two and can guide the bearing seat to slide down smoothly along the slope, so as to smoothly enter the vertically set second channel 82. In this process, the movement state of the bearing seat changes, gradually changing from a horizontal state to a vertical state.

[0086] After entering the second channel 82, since the bottom of the second channel 82 is inclined toward the outside of the workbench 20, the bearing seat slowly rolls along the inclined bottom under the component force of gravity, and finally rolls out of the workbench 20, completing the entire unloading process. Compared with traditional manual unloading or complex unloading devices, the feeding channel 80 has a simple structure, low cost, high unloading efficiency and good stability.

[0087] like Figure 5 and Figure 8As shown, the ejection member 49 includes an ejection spring 491 and a storage plate 492. The ejection spring 491 is vertically arranged at the bottom of the storage slot 44, and one end of the ejection spring 491 is connected to the bottom end of the storage slot 44, and the other end is connected to the lower surface of the storage plate 492. The storage plate 492 is slidably connected and adapted to the storage slot 44.

[0088] In the storage slot 44 of the feeding mechanism 40, the ejection member 49 plays a key role. When the feeding plate 43 transports the bearing seat to the clamping mechanism 30, the working process of the ejection member 49 is as follows. Initially, the feeding plate 43 is located below the stacking rack 41, and the bearing seat in the stacking rack 41 enters the storage slot 44 through the discharge port, and the bearing seat is located on the upper surface of the storage plate 492. At this time, the storage plate 492 is in the milling position in the storage slot 44. At this time, the ejection spring 491 is in a compressed state. When the feeding plate 43 is pushed out of the stacking rack 41, the ejection spring 491 begins to work. Since one end of the ejection spring 491 is firmly connected to the bottom of the storage slot 44, and the other end is connected to the lower surface of the storage plate 492, and the storage plate 492 is slidably connected and adapted to the storage slot 44, under the action of the ejection spring 491's own elastic force, the ejection spring 491 gradually stretches, pushing the storage plate 492 to slide upward along the storage slot 44. The rise of the storage plate 492 drives the bearing seat on it to rise together, so that a part of the bearing seat is gradually ejected from the storage slot 44, which is convenient for the clamping mechanism 30 to clamp. Compared with the traditional method of adjusting the bearing seat to a suitable clamping position with manual assistance, this ejection member 49 realizes automatic operation, reduces manual intervention, and improves work efficiency and production stability.

[0089] A second embodiment of the present invention provides a processing method, using the above-mentioned double-sided milling device for processing a bearing seat, the method comprises the following steps:

[0090] S1, loading: placing the bearing seat to be processed in the stacking rack 41, and transporting the bearing seat to the material taking position through the feeding mechanism 40;

[0091] S2. Clamping: The driving mechanism 60 drives the spindle 11 to rotate, driving the clamping mechanism 30 to rotate to the material taking position. After the clamping mechanism 30 clamps the bearing seat, the driving mechanism 60 drives the spindle 11 to rotate in the opposite direction to the milling position.

[0092] S3, coarse adjustment: the driving mechanism 60 drives the workbench 20 to rotate, so that the milling mechanism 50 enters the milling position, and the translation assembly 70 drives the mounting seat 51 to move along the radial direction of the spindle 11, so that the positions of the milling mechanism 50 and the clamping mechanism 30 correspond;

[0093] S4, fine adjustment: the adjustment component 54 drives the two fixed blocks 541 to approach each other in the vertical direction, so that the milling cutter 532 contacts the end surface of the bearing seat, and the flexible connector 52 provides buffering and adjusts the contact relationship between the milling cutter 532 and the surface of the bearing seat;

[0094] S5, milling: start the milling assembly 53, and perform double-sided milling processing on the bearing seat on the clamping mechanism 30;

[0095] S6, unloading: After the processing is completed, the clamping mechanism 30 releases the bearing seat, and the bearing seat rolls out of the workbench 20 through the feeding channel 80.

[0096] Before performing processing operations, first ensure that all parts of the equipment are correctly installed and in good operating condition. Check whether the line connections of the first motor 63, the second motor 66 in the drive mechanism 60, and the servo motor 531 that drives the milling cutter 532 to rotate are stable, and whether the parameter settings of each motor meet the processing requirements. At the same time, debug the feeding mechanism 40, the clamping mechanism 30, the milling mechanism 50, etc. to ensure their smooth movement. For example, manually operate the first cylinder 33 to check whether the movement of the mounting seat 51 along the first guide rail 48 is flexible and whether there is any jamming; test whether the clamping jaws 34 of the clamping mechanism 30 open and close normally and whether the clamping force is moderate.

[0097] The bearing seats to be processed are neatly placed in the stacking rack 41 according to certain rules, and then the feeding mechanism 40 starts to work, and the second cylinder 45 drives the feeding plate 43 to move. The feeding plate 43 is provided with a storage groove 44 adapted to the bearing seat on the side close to the stacking rack 41. When the feeding plate 43 moves to the bottom of the stacking rack 41, the bearing seat on the stacking rack 41 falls into the storage groove 44 through the discharge port. Subsequently, the feeding plate 43 is driven by power to transport the storage groove 44 carrying the bearing seat to the clamping mechanism 30;

[0098] The first motor 63 in the driving mechanism 60 is started, driving the first worm 62 to rotate, thereby rotating the first worm wheel 61 and the spindle 11, and driving the clamping mechanism 30 to rotate to the material taking position. The clamping jaws 34 in the clamping mechanism 30 are opened and accurately aligned with the bearing seat in the storage slot 44. Then, the clamping jaws 34 are closed to stably clamp the bearing seat. After the clamping is completed, the driving mechanism 60 drives the spindle 11 to rotate in the opposite direction to the milling position, ready for subsequent processing.

[0099] The second motor 66 in the driving mechanism 60 is started, driving the second worm 65 to rotate, and the second worm wheel 64 and the workbench 20 rotate accordingly, so that the milling mechanism 50 accurately enters the milling position. At the same time, the first cylinder 33 is started, and its piston rod pushes the mounting seat 51 to move along the first guide rail 48, and the milling mechanism 50 is preliminarily adjusted to a position close to the bearing seat.

[0100] The first cylinder 33 is started, and its piston rod pushes the mounting seat 51 to move along the first guide rail 48, and the milling mechanism 50 is initially adjusted to a position close to the bearing seat. At the same time, the second motor 66 in the driving mechanism 60 is started, driving the second worm 65 to rotate, and the second worm wheel 64 and the workbench 20 rotate accordingly, so that the milling mechanism 50 accurately enters the milling position.

[0101] The adjustment component 54 starts to work, and the motor inside it drives the screw 542 to rotate, and the two fixed blocks 541 threadedly connected to the screw 542 approach each other in the vertical direction. The milling cutter 532 installed on the fixed block 541 gradually contacts the end face of the bearing seat, and the flexible connector 52 plays a key role at this time. When the milling cutter 532 contacts the end face of the bearing seat, the buffer spring 526 first provides initial buffering to reduce the impact force; as the milling preparation proceeds, the non-Newtonian fluid 528 changes viscosity and hardness according to the force conditions, and further adjusts the contact pressure and fit between the milling cutter 532 and the surface of the bearing seat; the rubber buffer body 527 assists in buffering and maintains the overall structural stability of the flexible connector 52, ensuring that the contact relationship between the milling cutter 532 and the surface of the bearing seat is in the best state, providing good conditions for milling processing.

[0102] The servo motor 531 driving the milling cutter 532 to rotate is turned on, and the milling cutter 532 starts to rotate at high speed. During the milling process, close attention should be paid to milling parameters such as milling speed, feed rate, etc. These parameters should be reasonably adjusted according to factors such as the material of the bearing seat and the processing accuracy requirements. For example, for a bearing seat material with a higher hardness, the milling speed can be appropriately reduced and the feed rate can be increased to ensure processing efficiency and processing quality. It should be understood here that the first cylinder 33, the second cylinder 45, the first motor 63, the second motor 66, the third motor 543 and the servo motor 531 in the present invention are all electrically connected to a controller arranged on the workbench 20.

[0103] After the processing is completed, the cylinder inside the clamping mechanism 30 works in the reverse direction, so that the clamping jaws 34 release the bearing seat. Due to the action of gravity, the bearing seat falls into the feeding channel 80. The feeding channel 80 includes a first channel 81 arranged horizontally and a second channel 82 arranged vertically, which are connected by a transition slope 83. The bearing seat first falls into the first channel 81, and then enters the second channel 82 through the transition slope 83. During this process, the bearing seat changes from a horizontal state to a vertical state. The bottom of the second channel 82 is inclined, and the bearing seat slowly rolls out of the workbench 20 along the inclined bottom under the action of gravity to complete the unloading operation.

[0104] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
