Description

Technical Field

[0001] This invention relates to the field of bearing processing technology, specifically to an integrated machine for processing bearing outer rings that combines loading, unloading, and inspection, and its usage method. Background Technology

[0002] The outer ring of a bearing is the annular external part of a rolling bearing. It is generally installed in the bearing housing or machine housing bore. The inner side is provided with raceways to constrain the position of the rolling elements and bear radial or axial loads. It works with the inner ring and rolling elements to achieve rotational support. It is mostly a rigid ring structure.

[0003] The integrated bearing outer ring machining machine is an automated equipment that integrates automatic loading and unloading, bearing outer ring cutting, and finished product size and appearance inspection functions. It can realize continuous operation of workpiece loading, processing, unloading, and quality inspection without manual intervention, and is used to efficiently complete the precision machining and online quality inspection of bearing outer rings.

[0004] During the production process of integral machining of the bearing outer ring, key parts such as its outer circle, end face and raceway need to be finely ground to remove machining allowance and surface burrs, so as to ensure that the dimensional accuracy and surface finish of the outer ring meet the usage standards.

[0005] When performing grinding operations on bearing outer rings of different batches, the workpiece needs to be positioned and clamped. Existing positioning methods have obvious defects in the control of clamping force. If the clamping force is too small, the bearing outer ring is prone to loosening and displacement during processing. If the clamping force is too large, it will squeeze the workpiece and cause deformation, damaging the surface accuracy of the outer ring and easily causing raceway deformation, thus affecting the dimensional accuracy of the processing and the accuracy of subsequent inspection results. Therefore, in order to solve the above problems, an integrated bearing outer ring processing machine and its usage method that integrates loading, unloading and inspection are proposed.

[0010] As a further optimization of the present invention, a grinding mechanism is fixedly connected to the right end of the machine base, and a size and appearance inspection instrument is fixedly connected to the left end of the machine base.

[0011] As a further optimization of the present invention, the lifting drive assembly includes a top plate, the inner side of which is fixedly connected to the cylinder body of an electric hydraulic cylinder, a limit post is slidably connected to the inner side of the top plate, a sleeve plate is fixedly connected to the bottom end of the limit post, and the end of the piston rod of the electric hydraulic cylinder is fixedly connected to the sleeve plate.

[0012] As a further optimization of the present invention, the sleeve is sleeved on the outside of the positioning cylinder, and an internal limiting plate is fixedly connected to the inside of the sleeve. The internal limiting plate slides inside the groove opened in the positioning cylinder.

[0014] As a further optimization of the present invention, the positioning cylinder has a track groove on its inner side, and the inner side of the track groove is slidably connected to the guide block.

[0015] As a further optimization of the present invention, the positioning cylinder is fixedly connected to a positioning ring at its bottom end, a positioning groove is provided on the inner side of the positioning ring, the inner side of the positioning groove is rotatably connected to the inner side of the limiting shaft, the push arm extends out of the inner side of the rotating cylinder, and a transmission shaft is fixedly connected to the top end of the positioning cylinder.

[0017] A method for using an integrated machine for machining bearing outer rings that combines loading, unloading, and inspection;

[0018] S1: The conveyor belt conveys the outer ring of the bearing. The feeding mechanism clamps the workpiece and places it on the turntable. The first servo motor drives the turntable to rotate and convey the workpiece, so that the center of the workpiece is aligned with the center of the positioning cylinder. The electric hydraulic cylinder drives the positioning component to calibrate and fix the workpiece. The grinding mechanism performs grinding. The second servo motor drives the clamping component and the workpiece to rotate synchronously to achieve full-circumference grinding. After grinding, the workpiece is conveyed by the feeding mechanism to the size and appearance inspection instrument for inspection and unloading. Other workpieces are ground simultaneously during the inspection station operation.

[0019] S2: The electric hydraulic cylinder drives the sleeve plate to move down, the built-in limit plate slides along the slide groove, and drives the pressurizing component and the positioning component to move down to the shaft seat and contact the turntable. The pressure plate squeezes the spring, pushes the cover plate down, and the protrusion slides along the spiral groove to drive the shaft column to rotate. Through the shaft seat and the circular plate, the push arm slides along the rotating cylinder, driving the clamping expansion claw to expand radially. The limit shaft rotates in the positioning groove to achieve the clamping expansion claw to fit and position against the inner wall of the outer ring of the bearing.

[0020] S3: Control the downward stroke of the electric hydraulic cylinder piston rod according to the bearing outer ring size. After the clamping claw is in contact with the inner wall of the workpiece, the shaft column stops rotating. The laser speed sensor detects and determines the direction of the electric hydraulic cylinder stroke. The pressure plate adjusts the spring compression to change the radial expansion force of the push arm and clamping claw, thereby controlling the clamping force.

[0021] S4: The electric hydraulic cylinder drives the whole unit to move upward, and the spring force maintains the positioning component and the workpiece in contact. After the cover plate is fully reset, the spring drives the component to move upward, and the push arm and clamping claw retract radially, releasing the clamping and fixing of the bearing outer ring.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. In this invention, by setting up a feeding mechanism, a size and appearance inspection instrument, and a turntable, the device can simultaneously carry out other bearing outer ring grinding operations while inspecting the workpiece during the processing and inspection of the bearing outer ring, which greatly improves the overall processing efficiency, reduces labor costs, and ensures the standardization and continuity of each process operation, reducing the impact of human operation errors on processing and inspection quality.

[0024] 2. In this invention, by setting up an electric hydraulic cylinder, a shaft seat, and a clamping expansion claw, the device can be adapted to various types of bearing outer rings without having to replace the positioning mold one by one, which greatly reduces the time and cost of mold replacement, improves the adaptability and operational flexibility of the equipment, and reduces the complexity of operation.

[0025] 3. In this invention, by setting up an electric hydraulic cylinder, a positioning cylinder, and a spring, the device can prevent the bearing outer ring from loosening or shifting due to insufficient clamping force, and also avoid workpiece deformation, surface precision damage, and raceway deformation caused by excessive clamping force. This ensures the accuracy of processing dimensions and the accuracy of subsequent inspection results, adapts to the processing requirements of bearing outer rings of different specifications, and improves the equipment's versatility and processing qualification rate.

Through the above settings, the grinding and transmission components can be stably supported, the bearing outer ring can be accurately conveyed and rotated, the grinding process can be continuously and stably operated, and the processing continuity can be improved.

[0047] As a further implementation of this solution, a grinding mechanism 12 is fixedly connected to the right end of the machine tool 11, and a size and appearance inspection instrument 3 is fixedly connected to the left end of the machine tool 11. Through the above settings, the processing station and the inspection station are arranged in separate areas, and grinding and inspection operations can be carried out simultaneously, thereby improving the overall processing efficiency and shortening the production cycle.

[0048] As a further implementation of this solution, the lifting drive assembly 4 includes a top plate 41, the inner side of which is fixedly connected to the cylinder body of the electric hydraulic cylinder 42, a limit post 45 is slidably connected to the inner side of the top plate 41, a sleeve plate 46 is fixedly connected to the bottom end of the limit post 45, and the end of the piston rod of the electric hydraulic cylinder 42 is fixedly connected to the sleeve plate 46. Through the above settings, the clamping mechanism provides stable power output, realizes precise vertical displacement of the clamping component, facilitates flexible adjustment of the clamping stroke, and adapts to different working conditions and adjustment requirements.

[0049] As a further implementation of this solution, the sleeve 46 is sleeved on the outside of the positioning cylinder 51, and the inner side of the sleeve 46 is fixedly connected to the built-in limiting plate 43. The built-in limiting plate 43 slides on the inner side of the slide groove 55 opened in the positioning cylinder 51. Through the above settings, the movement trajectory of the clamping component is constrained, ensuring smooth and coaxial vertical movement, avoiding offset and jamming, and improving the accuracy and stability of the clamping action.

[0050] As a further implementation of this solution, an outer ring plate 52 is sleeved on the outside of the positioning cylinder 51, and a horizontal plate 53 is slidably connected to the inside of the slide groove 55. The horizontal plate 53 is fixedly connected to the inside of the outer ring plate 52. A pressure plate 54 is fixedly connected to one side of the horizontal plate 53. The pressure plate 54 is embedded in the inside of the positioning cylinder 51. The bottom end of the built-in limiting plate 43 is fixedly connected to the top end of the pressure plate 54. The bottom end of the pressure plate 54 is fixedly connected to the top end of the spring 62. Through the above settings, the power can be reliably transmitted to the elastic buffer component, realizing flexible adjustment of the clamping force, avoiding workpiece extrusion deformation caused by rigid clamping, and ensuring the machining accuracy of the outer ring.

[0051] As a further implementation of this solution, a rail groove 56 is provided on the inner side of the positioning cylinder 51. The inner side of the rail groove 56 is slidably connected to the guide block 65. Through the above setting, a limit guide is provided for the elastic adjustment component, ensuring smooth movement of the force adjustment component, preventing jamming, and improving the sensitivity and stability of the clamping force adjustment.

[0052] As a further implementation of this solution, a positioning ring 57 is fixedly connected to the bottom of the positioning cylinder 51, and a positioning groove 58 is opened on the inner side of the positioning ring 57. The inner side of the positioning groove 58 is rotatably connected to the inner side of the limiting shaft 77. The push arm 75 extends out of the inner side of the rotating cylinder 76, and a transmission shaft 44 is fixedly connected to the top of the positioning cylinder 51. Through the above settings, multiple sets of clamping parts can be flexibly rotated and expanded to adapt to the positioning of the outer ring of bearings with different inner diameters. There is no need to change the mold, which improves the versatility and adaptability of the equipment.

[0053] As a further implementation of this solution, a protrusion 64 is fixedly connected to the inner side of the push cylinder 63, and a spiral groove 72 is opened on the outer side of the shaft column 71. The protrusion 64 slides on the inner side of the spiral groove 72, and the shaft column 71 is rotatably connected to the inner side of the positioning cylinder 51 through the bearing. Through the above arrangement, the vertical power is converted into radial expansion force, which smoothly drives the clamping part to fit the workpiece, ensuring uniform clamping force and preventing the outer ring from loosening, shifting, or undergoing local deformation.

[0054] Workflow: Example 1: During loading, processing, and inspection, the loading mechanism 2 is placed near the conveyor belt, which transports the bearing outer ring. The loading mechanism 2 clamps the bearing outer ring and places it on a predetermined position on the upper end of the turntable 14. A gap is provided between the bottom of the turntable 14 and the top of the machine base 11. The first servo motor 13 is started to drive the turntable 14 to rotate, transporting the bearing outer ring to the lower end of the center positioning seat assembly 5, so that the center of the bearing outer ring is approximately aligned with the center of the positioning cylinder 51. At this time, the positioning assembly 7 is calibrated and fixed by controlling the electric hydraulic cylinder 42. Then, the bearing outer ring is polished by the grinding mechanism 12. During the grinding process, the second servo motor 16 is activated to drive the transmission shaft 44 to rotate. The transmission shaft 44 drives the lifting drive assembly 4, the center positioning seat assembly 5, the pressurizing assembly 6, and the positioning assembly 7 to rotate simultaneously. The positioning assembly 7 drives the outer ring of the bearing to rotate, thereby achieving the effect of grinding the outer side of the bearing outer ring. After grinding, the outer ring of the bearing is transported by the first servo motor 13 to the left-end loading mechanism 2. The left-end loading mechanism 2 places the outer ring of the bearing on the size and appearance inspection instrument 3 for inspection. After inspection, the left-end loading mechanism 2 unloads the bearing. This allows other bearing outer rings to be ground during the inspection process, improving processing efficiency.

[0055] Example 2: When fixing the outer ring of the bearing, the electric hydraulic cylinder 42 is activated to move the sleeve 46 downward. The built-in limiting plate 43 slides inside the slide groove 55. At the same time, the sleeve 46 moves the limiting post 45, which slides inside the top plate 41. Before this, the sleeve 46 is located at the top of the slide groove 55, with the top of the sleeve 46 in contact with the positioning cylinder 51. The bottom of the built-in limiting plate 43 is fixedly connected to the top of the pressure plate 54, and the bottom of the pressure plate 54 is fixedly connected to the top of the spring 62. At this time, the pressurizing component 6 and the positioning component 7 move downward simultaneously until the lower end of the bearing seat 73 contacts the top of the turntable 14. A ball is fixedly connected to the bottom of the lower end of the bearing seat 73, which reduces the friction during the rotation of the ball. When the pressure plate 54 presses the spring 62, the spring 62 pushes the cover plate 61 downward. The guide block 65 slides inside the rail groove 56, and the protrusion 64 slides outside the spiral groove 72. At this time, the shaft column 71 rotates. The rotation of the shaft column 71 drives the shaft seat 73 and the circular plate 74 to rotate simultaneously. Since the push arm 75 is rotatably connected to the shaft seat 73, the push arm 75 slides inside the rotating cylinder 76 while being pushed by the circular plate 74. This causes multiple push arms 75 and clamping expansion claws 78 to expand outward simultaneously. During this process, the limiting shaft 77 rotates inside the positioning groove 58, so that the clamping expansion claws 78 fit against the inner side of the bearing outer ring. When positioning the bearing outer ring, it can be adapted to various types of bearing outer rings without changing the mold one by one.

[0056] Example 3: When adjusting the clamping force according to the size of the bearing outer ring, firstly, according to the size of the bearing outer ring of this batch, control the downward movement distance of the piston rod of the electric hydraulic cylinder 42. When the clamping expansion claw 78 is in contact with the inner side of the bearing outer ring, the shaft column 71 cannot rotate. A laser speed sensor is installed on the inner side of the positioning cylinder 51 to detect the rotation of the shaft column 71. When the shaft column 71 stops rotating, the stroke of the piston rod of the electric hydraulic cylinder 42 is controlled. At this time, the spring 62 is compressed by the pressure plate 54, and the compression amount of the spring 62 is controlled, so that the multiple push arms 75 and the clamping expansion claw 78 maintain the outward expansion trend. Control the force of the clamping expansion claw 78 in contact with the bearing outer ring, so as to prevent the bearing outer ring from easily loosening or shifting due to insufficient clamping force, and the workpiece from being squeezed and deformed due to excessive clamping force.

[0057] Example 4: When the positioning component 7 is reset, the electric hydraulic cylinder 42 is controlled to move upward. When the spring 62 is not reset, the spring force of the spring 62 ensures that the positioning component 7 is kept inside the outer ring of the bearing. When the cover plate 61 is reset, the spring 62 drives the cover plate 61 and the push cylinder 63 to move upward. At this time, the multiple push arms 75 and the clamping claws 78 are retracted, and the multiple clamping claws 78 move away from the outer ring of the bearing, releasing the fixation of the outer ring of the bearing.

S2: The electric hydraulic cylinder (42) drives the sleeve plate (46) to move down, the built-in limiting plate (43) slides along the slide groove (55), driving the pressurizing component (6) and the positioning component (7) to move down to the bearing seat (73) and contact the turntable (14), the pressure plate (54) squeezes the spring (62), pushes the cover plate (61) to move down, the protrusion (64) slides along the spiral groove (72) to drive the shaft column (71) to rotate, and through the shaft seat (73) and the round plate (74) transmission, the push arm (75) slides along the rotating cylinder (76), driving the clamping expansion claw (78) to expand radially, and the limiting shaft (77) rotates in the positioning groove (58) to realize the clamping expansion claw (78) to fit and position with the inner wall of the outer ring of the bearing; S3: Based on the outer ring size of the bearing, control the downward stroke of the piston rod of the electric hydraulic cylinder (42). After the clamping expansion claw (78) is in contact with the inner wall of the workpiece, the shaft column (71) stops rotating. The laser speed sensor detects and determines the stroke of the electric hydraulic cylinder (42). The compression amount of the spring (62) is adjusted by the pressure plate (54), and the radial expansion force of the push arm (75) and the clamping expansion claw (78) is changed, thereby controlling the clamping force. S4: The electric hydraulic cylinder (42) drives the whole to move upward, and the spring (62) maintains the positioning component (7) in contact with the workpiece. After the cover plate (61) is fully reset, the spring (62) drives the component to move upward, and the push arm (75) and the clamping claw (78) retract radially to release the clamping and fixing of the bearing outer ring.
