Description

Technical Field

[0001] This application relates to the field of parts processing technology, and in particular to an automatic feeding device for stepped bearings. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical bodies, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. Stepped bearings are an important component of bearings. They are mainly cylindrical, with a larger diameter at one end and a smaller diameter at the other end along the axial direction. Currently, during the production process, stepped bearing components need to be transported to the processing equipment via a feeding track.

[0003] To reduce the floor space occupied by the production line, the conveyor track is usually composed of two straight tracks that are perpendicular to each other. During the conveying of the stepped bearing components, it is necessary to ensure that the axial orientation of all workpieces is consistent, such as the large end facing the feeding direction of the processing equipment. If the axial orientation of each stepped bearing component is disordered, it will cause the subsequent processing station to be unable to be accurately positioned, resulting in processing failure or increased scrap rate.

[0004] In the existing technology, the loading of stepped bearing components is mainly done manually. That is, workers continuously place and load the bearing components at the beginning of the feeding track. However, workers are prone to fatigue under long-term repetitive operation, which leads to a decrease in loading efficiency. At the same time, it is difficult to ensure that the axial orientation of each workpiece is uniform, and the posture accuracy of the bearing components is reduced, which has obvious shortcomings. Utility Model Content

[0005] To improve the feeding efficiency and posture accuracy of bearing components, this application provides an automatic feeding device for stepped bearings.

[0006] The automatic feeding device for stepped bearings provided in this application adopts the following technical solution: An automatic feeding device for stepped bearings includes a frame with a first feeding track and a second feeding track perpendicular to each other. A feeding mechanism is provided at the inlet end of the first feeding track, and a reversing table is provided at the outlet end of the first feeding track. A detection component, a correction component, and a transfer component are provided on the reversing table. The detection component is used to detect the axial posture of the workpiece at the end of the first feeding track. The correction component is used to correct the axial posture of the workpiece to a uniform direction. The transfer component transfers the workpiece corrected by the correction component to the second feeding track.

[0007] By adopting the above technical solution, during the feeding process, the worker can automatically feed the workpiece through the feeding mechanism. When the first feeding track transports the workpiece to the end, the detection component detects the axial orientation of the workpiece. If an axial deviation is detected, the correction component calibrates the axial orientation of the workpiece to ensure that the axial orientation of the workpiece meets the requirements of the subsequent processing station. After the correction is qualified, the transfer component transfers it from the discharge end of the first feeding track to the second feeding track, and the second feeding track transports the workpiece to the next processing station. In this way, the automatic feeding of the workpiece is realized, and the axial posture of the workpiece can be automatically corrected before entering the second feeding track. There is no need for the worker to continuously place and feed the bearing components at the feed end of the first feeding track, which improves the feeding efficiency and posture accuracy of the bearing components.

[0008] Optionally, the detection component includes a blocking block disposed on the reversing table, the blocking block extending into the first feeding track, and a sensor for detecting the diameter of the workpiece disposed on the blocking block, the sensor controlling the correction direction of the correction component through a control system.

[0009] By adopting the above technical solution, when the workpiece reaches the reversing table, the blocking block blocks the workpiece, causing it to stop at the detection position. At this time, the sensor detects the diameter of the workpiece end, identifies whether the end facing the blocking block is the large end or the small end of the workpiece, and transmits the detection signal to the control system. The control system determines whether the axial direction of the workpiece meets the subsequent processing requirements based on the diameter information fed back by the sensor, and then controls the correction direction of the correction component, thus realizing the automatic detection of the axial direction of the workpiece.

[0010] Optionally, the straightening assembly includes a lifting cylinder mounted on the reversing platform. A turntable is mounted on the piston rod end of the lifting cylinder. A rotating platform is mounted on the rotating shaft of the turntable. The sensor controls the rotation of the turntable through a control system. A limit groove is provided on the rotating platform. A pushing cylinder is mounted on the reversing platform. A pushing block is mounted on the output end of the pushing cylinder. A first centering cylinder and a second centering cylinder are mounted on the reversing platform. A connecting arm is fixedly connected to the output end of the second centering cylinder. An adjusting column for pushing the workpiece is fixedly connected to the connecting arm and the output end of the first centering cylinder.

[0011] By adopting the above technical solution, the pushing cylinder drives the pushing block to move towards the workpiece, pushing the workpiece into the limiting groove of the rotary table. The limiting groove initially constrains the workpiece to prevent it from deviating during the pushing process. Then, the lifting cylinder is activated to drive the rotary table to rise, so that the top surface of the rotary table is higher than the top surface of the first feeding track. According to the workpiece axial information detected by the sensor, the control system instructs the rotary table to rotate 90° clockwise or counterclockwise, smoothly changing the workpiece from a horizontal state to a vertical state, while ensuring that the axial orientation of all workpieces is consistent. Finally, the first and second centering cylinders are activated simultaneously, driving the two adjusting columns to move closer to the workpiece. Through the synchronous pushing of the two adjusting columns, the workpiece is pushed to the preset position inside the rotary table, matching the gripping or conveying position of the subsequent transfer components, thus completing the entire correction process.

[0012] Optionally, the transfer assembly includes a connecting platform disposed on the reversing table. The connecting platform is inclined from top to bottom along the direction close to the second feeding track. A first transfer cylinder is disposed on the reversing table. The first transfer cylinder extends along the first feeding track into the interior of the connecting platform. A second transfer cylinder is disposed on the moving part of the first transfer cylinder. The piston rod of the second transfer cylinder is provided with a pneumatic gripper.

[0013] By adopting the above technical solution, after the correction is completed, the first transfer cylinder drives the pneumatic gripper to move towards the rotary table until the pneumatic gripper aligns with the workpiece at the preset station. Then, the second transfer cylinder drives the pneumatic gripper to move downward to the height of the rotary table, and the pneumatic gripper pneumatically clamps the workpiece. Then, the moving part of the first transfer cylinder drives the pneumatic gripper clamping the workpiece to move along the first feeding track until the workpiece is transported to the top of the connecting table. Finally, the pneumatic gripper releases the workpiece, and the second transfer cylinder drives the pneumatic gripper to move upward. Under its own gravity, the workpiece slides along the inclined surface of the connecting table from top to bottom and finally enters the feeding end of the second feeding track, completing the entire transfer process.

[0014] Optionally, the feeding mechanism includes a storage box disposed on the frame, an installation frame disposed at the end of the storage box near the first feeding track, a plurality of lifting components disposed in the installation frame, the bottom surface of the storage box being inclined from top to bottom along the direction near the first feeding track, the lifting components being used to lift a plurality of workpieces on the bottom wall of the storage box into the first feeding track, and a screening component in a supine screening posture disposed on the installation frame.

[0015] By adopting the above technical solution, during loading, workers place multiple workpieces into the storage box. Under their own gravity, the workpieces roll along the bottom wall of the storage box to the lifting component. The lifting component then lifts the workpieces to the height of the first feeding track. The screening component screens the workpieces and allows workpieces in a prone position to enter the first feeding track. Finally, the first feeding track transports the prone workpieces to the reversing table for axial posture adjustment. This achieves automated loading of bearing components. The entire loading process only requires workers to dump a large number of components into the storage box, eliminating the need for workers to manually place workpieces individually. This significantly reduces the workload of workers performing repetitive operations for extended periods, thereby further improving the loading efficiency of bearing components.

[0016] Optionally, the lifting assembly includes a support plate fixedly disposed within the mounting frame, a lifting plate slidably disposed on the side of the support plate near the storage box, a driving component disposed within the mounting frame to drive the lifting plate to move vertically, the height of the plurality of support plates increasing sequentially along the direction close to the first feeding track, and the top surface height of the support plate close to the first feeding track being flush with the height of the first feeding track.

[0017] By adopting the above technical solution, when the workpiece rolls to the lifting plate closest to the storage box, the driving component drives the lifting plate to slide upward to the height of the corresponding support plate. The workpiece is transferred from the lifting plate to the support plate, and then from the support plate to the next adjacent lifting plate. This cycle continues until the workpiece is transferred to the support plate closest to the feeding track. The automatic lifting of multiple workpieces is achieved through the stepped movement of multiple lifting components.

[0018] Optionally, the top surface of the lifting plate is provided with a stepped groove, and the top surface of the support plate has a slope that slopes downward toward the feeding track.

[0019] By adopting the above technical solution, the stepped groove makes the workpiece stable when it moves with the lifting plate, reducing the possibility of the workpiece falling off the lifting plate. The inclined slope of the support plate makes the workpiece slide and transfer automatically towards the feeding track under the action of gravity, making the transfer process of the workpiece on the support plate smoother and reducing the occurrence of stagnation and jamming, thereby further improving the workpiece feeding efficiency.

[0020] Optionally, the screening component includes a mounting base disposed on the top of the mounting frame, a connecting shaft rotatably connected within the mounting base, a screening frame disposed on the connecting shaft, a blocking rod fixedly disposed within the screening frame along its length, the bottom surface of the blocking rod abutting against the surface of the prone workpiece, a cam coaxially disposed at the end of the connecting shaft extending out of the mounting base, a driving cylinder disposed on the outer surface of the mounting frame, and the piston rod of the driving cylinder hinged to the protruding end of the cam.

[0021] By adopting the above technical solution, when the workpiece is transferred to the top support plate, the blocking rod abuts against the top surface of the workpiece in a prone position, so that the workpiece in a prone position is limited to the support plate, while the blocking rod abuts against the upper half of the workpiece in a vertical position, and the protruding blocking rod generates a pushing force on the workpiece, so that it falls into the storage box when it contacts the blocking rod. After screening is completed, the drive cylinder extends and drives the cam to rotate. The cam drives the screening frame on the connecting shaft to rotate upward in the direction away from the storage box. At this time, the workpiece in a prone position rolls onto the first feeding mechanism, thus realizing the automatic screening of the workpiece.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. This application sets up a detection component, a correction component, and a transfer component. When the first feeding track transports the workpiece that has undergone preliminary screening to the end, the detection component will further detect the axial orientation of the workpiece. If the axial orientation deviation of the workpiece is detected, the correction component will calibrate the axial orientation of the workpiece to ensure that the axial orientation of the workpiece meets the requirements of the subsequent processing station. After the correction is qualified, the transfer component will transfer it from the discharge end of the first feeding track to the second feeding track, and the second feeding track will transport the workpiece to the next processing station. In this way, the axial posture of the workpiece can be automatically corrected before entering the second feeding track, eliminating the need for workers to continuously place and load bearing components at the feed end of the first feeding track, thereby improving the loading efficiency and posture accuracy of bearing components. 2. This application, by setting up a feeding mechanism, allows workers to place multiple workpieces into the storage box during feeding. Under their own gravity, the workpieces roll along the bottom wall of the storage box to the lifting mechanism. The lifting mechanism then lifts the workpieces to the height of the first feeding track. The screening component screens the workpieces and allows workpieces in a prone position to enter the first feeding track. Subsequently, the first feeding track transports workpieces in the correct position. This achieves automated feeding of bearing components. The entire feeding process only requires workers to pour a large number of components into the storage box, eliminating the need for workers to manually place workpieces individually. This significantly reduces the workload of workers performing repetitive operations for extended periods, thereby improving the feeding efficiency of bearing components. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses an automatic feeding device for stepped bearings.

[0030] Reference Figure 1 and Figure 2 An automatic feeding device for stepped bearings includes a frame 1, on which a first feeding track 101 and a second feeding track 102 are mounted. The second feeding track 102 is perpendicular to the first feeding track 101. Both the first and second feeding tracks are common devices with linear conveying functions, and their specific composition and working principle are existing technologies, which will not be described in detail in this embodiment. A reversing table 103 is installed on the frame 1 at the discharge end of the first feeding track 101. The reversing table 103 is equipped with a detection component 2, a correction component 3, and a transfer component 4, thereby realizing the reversing conveying of the workpiece between the first feeding track 101 and the second feeding track 102.

[0031] Reference Figure 2 and Figure 3 The detection component 2 includes a blocking block 21 fixed on the reversing table 103. The blocking block 21 extends into the first feeding track 101 to obstruct the movement of the workpiece. A sensor 22 for detecting the diameter of the workpiece is fixedly installed on the end face of the blocking block 21 facing the first feeding track 101. In this embodiment, the sensor 22 is a distance sensor 22. The sensor 22 controls the correction direction of the correction component 3 through the control system.

[0032] Reference Figure 2 and Figure 3The correction component 3 includes a lifting cylinder 31 installed at the bottom of the reversing table 103. A turntable 32 is installed at the piston rod end of the lifting cylinder 31. The turntable 32 is a common drive device with rotation function. Its specific principle is existing technology and will not be described in detail in this embodiment. A rotating table 33 is fixedly connected to the rotation axis of the turntable 32. The sensor 22 controls the rotation direction of the turntable 32 through the control system. The turntable 32 rotates 90 degrees each time to adjust the workpiece parallel to the first feeding track 101 to a vertical state. The rotating table 33 has limiting grooves 331 for limiting along both the width and length directions. The side of the rotating table 33 near the first feeding mechanism has an inclined slope to facilitate the transfer of the workpiece.

[0033] Reference Figure 2 and Figure 3 A pusher cylinder 34 is fixedly installed on the reversing table 103. A pusher block 35 is fixedly connected to the output end of the pusher cylinder 34. A first centering cylinder 36 and a second centering cylinder 37 are installed on the reversing table 103. A connecting arm 38 is fixedly connected to the output end of the second centering cylinder 37. An adjusting column 39 for pushing the workpiece is fixedly connected to the connecting arm 38 and the output end of the first centering cylinder 36. The center lines of the two adjusting columns 39 and the limiting groove 331 are on the same straight line. The first centering cylinder 36 and the second centering cylinder 37 are located above the first feeding track 101.

[0034] Reference Figure 2 and Figure 3 The transfer assembly 4 includes a connecting platform 41 mounted on the reversing table 103. The connecting platform 41 connects the discharge end of the first feeding track 101 and the infeed end of the second feeding track 102. The connecting platform 41 is inclined from top to bottom along the direction close to the second feeding track 102. A limiting plate 411 for limiting the workpiece is fixedly connected inside the connecting platform 41 along the length direction. The limiting area of ​​the limiting plate 411 matches the limiting groove 331 in the rotary table 33.

[0035] Reference Figure 2 and Figure 3 A first transfer cylinder 42 is installed on the reversing table 103 along the straight direction of the first feeding track 101. In this embodiment, the first transfer cylinder 42 is a linear rodless cylinder. The first transfer cylinder 42 extends along the first feeding track 101 into the connecting table 41. A second transfer cylinder 43 is fixedly connected to the moving part of the first transfer cylinder 42. The piston rod of the second transfer cylinder 43 moves perpendicular to the first transfer cylinder 42. A pneumatic gripper 44 for clamping the workpiece is installed on the piston rod of the second transfer cylinder 43. The principle and specific composition of the pneumatic gripper 44 are existing technologies and will not be described in detail in this embodiment.

[0036] When the first feeding track 101 transports the workpiece to the end of the blocking block 21, the blocking block 21 blocks the workpiece and stops the workpiece at the detection position. At this time, the sensor 22 detects the diameter of the end of the workpiece and identifies whether the end of the workpiece is facing the blocking block 21 or the end of the workpiece. After the inspection is completed, the inspection signal is transmitted to the control system. The pusher cylinder 34 drives the pusher block 35 to move towards the workpiece and pushes the workpiece into the limiting groove 331 of the rotary table 33. The limiting groove 331 forms a preliminary constraint on the workpiece to prevent the workpiece from deviating during the pushing process. Then, the lifting cylinder 31 starts to drive the rotary table 32 to rise, so that the top surface of the rotary table 33 is higher than the first feeding track 101. According to the workpiece axial information detected by the sensor 22, the control system instructs the rotary table 32 to drive the rotary table 33 to rotate 90° clockwise or counterclockwise, changing the workpiece from a horizontal state to a vertical state. This ensures that the axial orientation of all workpieces is consistent. Finally, the first centering cylinder 36 and the second centering cylinder 37 start synchronously, driving the two adjusting columns 39 to move closer to the workpiece. Through the synchronous pushing of the two adjusting columns 39, the workpiece is pushed to the center position of the rotary table 33. After the correction is completed, the first transfer cylinder 42 drives the pneumatic gripper 44 to move towards the rotary table 33 until the pneumatic gripper 44 is aligned with the workpiece at the preset station. Then, the second transfer cylinder 43 drives the pneumatic gripper 44 to move downward to the height of the rotary table 33, and the pneumatic gripper 44 pneumatically clamps the workpiece. Next, the moving part of the first transfer cylinder 42 drives the pneumatic gripper 44 clamping the workpiece to move along the first feeding track 101 until the workpiece is transported to the top of the connecting table 41. Finally, the pneumatic gripper 44 releases the workpiece. The transfer cylinder 43 drives the pneumatic gripper 44 to reset upwards, while the lifting cylinder 31 drives the rotary table 33 to move downwards and reset. Under its own gravity, the workpiece slides along the inclined surface of the connecting table 41 from top to bottom and finally enters the feeding end of the second feeding track 102. This allows the axial posture of the workpiece to be automatically corrected before entering the second feeding track 102, eliminating the need for workers to continuously place and load bearing components at the feeding end of the first feeding track 101, thus improving the loading efficiency and posture accuracy of the bearing components.

[0037] Reference Figure 1 and Figure 4 In order to further improve the workpiece loading efficiency, the frame 1 is equipped with a loading mechanism 5 at the feeding end of the first feeding track 101. The loading mechanism 5 includes a storage box 51. The end of the storage box 51 near the first feeding track 101 is connected to a mounting frame 52. The bottom surface of the storage box 51 is inclined from top to bottom along the direction near the first feeding track 101. After the workpiece is poured into the storage box 51, it can roll to the side of the mounting frame 52 under its own gravity.

[0038] Reference Figure 1 and Figure 4The mounting frame 52 is provided with multiple lifting components 53. In this embodiment, there are three lifting components 53. Each lifting component 53 includes a support plate 531 fixedly installed in the mounting frame 52. The top surface of the support plate 531 has a slope that slopes downward toward the first feeding track 101, so that the workpiece moves spontaneously toward the first feeding track 101 under the action of gravity. A lifting plate 532 is slidably connected to the side of the support plate 531 near the storage box 51. The top surface of the lifting plate 532 is provided for limiting the workpiece. The stepped groove 5321 and the mounting frame 52 are provided with a driving component (not shown in the figure) that drives the lifting plate 532 to move to the height of the support plate 531. The driving component can be a linear cylinder or other linear drive component. The height of multiple support plates 531 increases sequentially along the direction close to the first feeding track 101. The top surface height of the support plate 531 close to the first feeding track 101 is flush with the height of the first feeding track 101. During operation, the lifting plate 532 moves from the height of the previous support plate 531 to the height of the same group of support plates 531.

[0039] During loading, the worker places multiple workpieces into the storage box 51. Under their own weight, the workpieces roll along the bottom wall of the storage box 51 to the lifting plate 532 closest to the storage box 51. The driving component drives the lifting plate 532 to slide upward to the height of the corresponding support plate 531. The workpiece rolls along the slope of the support plate 531 to the next lifting plate 532. Then the driving component drives the lifting plate 532 to slide upward to the height of the corresponding support plate 531. This cycle continues until the workpiece is transferred to the support plate 531 closest to the first feeding track 101. In this way, multiple workpieces are lifted vertically.

[0040] Reference Figure 1 and Figure 4 A screening component 6 is provided on the mounting frame 52. The screening component 6 includes a mounting base 61 fixed to the top of the mounting frame 52. A connecting shaft 62 is rotatably connected inside the mounting base 61. The connecting shaft 62 is parallel to the straight direction of the first feeding track 101. A screening frame 63 is detachably connected to the connecting shaft 62. A blocking rod 64 is fixedly installed inside the screening frame 63 along the straight direction. The end of the blocking rod 64 extends into the interior of the top support plate 531. When the workpiece rises to the top, the bottom surface of the blocking rod 64 abuts against the surface of the lying workpiece. A cam 65 is coaxially fixedly connected to the end of the connecting shaft 62 extending out of the mounting base 61. A drive cylinder 66 is installed on the outer surface of the mounting frame 52. The piston rod of the drive cylinder 66 is hinged to the protruding end of the cam 65.

[0041] When the workpiece is transferred to the top support plate 531, the blocking rod 64 abuts against the top surface of the workpiece in a prone position, thus limiting the workpiece in a prone position to the support plate 531. The blocking rod 64 abuts against the upper half of the workpiece in a vertical position, and the protruding blocking rod 64 exerts a pushing force on the workpiece, causing it to fall into the storage box 51 when it comes into contact with the blocking rod 64. After screening is completed, the drive cylinder 66 extends and drives the cam 65 to rotate. The cam 65 drives the screening frame 63 on the connecting shaft 62 to rotate upward in the direction away from the storage box 51. At this time, the workpiece in a prone position rolls onto the first feeding mechanism, thus realizing the automatic screening of the workpiece.

[0042] The implementation principle of the automatic feeding device for stepped bearings in this application embodiment is as follows: During feeding, the worker pours multiple workpieces into the storage box 51, and the feeding mechanism 5 automatically feeds the workpieces. When the first feeding track 101 transports the workpiece to the end of the blocking block 21, the blocking block 21 blocks the workpiece, causing the workpiece to stop at the detection position. At this time, the sensor 22 detects the diameter of the end of the workpiece and identifies whether the end facing the blocking block 21 is the large end or the small end of the workpiece. After the inspection is completed, the inspection signal is transmitted to the control system. The pusher cylinder 34 drives the pusher block 35 to move towards the workpiece and pushes the workpiece into the limiting groove 331 of the rotary table 33. The limiting groove 331 forms a preliminary constraint on the workpiece to prevent the workpiece from deviating during the pushing process. Then, the lifting cylinder 31 starts to drive the rotary table 32 to rise, so that the top surface of the rotary table 33 is higher than the first feeding track 101. According to the workpiece axial information detected by the sensor 22, the control system instructs the rotary table 32 to drive the rotary table 33 to rotate 90° clockwise or counterclockwise, changing the workpiece from a horizontal state to a vertical state. This ensures that the axial orientation of all workpieces is consistent. Finally, the first centering cylinder 36 and the second centering cylinder 37 start synchronously, driving the two adjusting columns 39 to move closer to the workpiece. Through the synchronous pushing of the two adjusting columns 39, the workpiece is pushed to the center position of the rotary table 33. After the correction is completed, the first transfer cylinder 42 drives the pneumatic gripper 44 to move towards the rotary table 33 until the pneumatic gripper 44 is aligned with the workpiece at the preset station. Then, the second transfer cylinder 43 drives the pneumatic gripper 44 to move downward to the height of the rotary table 33, and the pneumatic gripper 44 pneumatically clamps the workpiece. Next, the moving part of the first transfer cylinder 42 drives the pneumatic gripper 44 clamping the workpiece to move along the first feeding track 101 until the workpiece is transported to the top of the connecting table 41. Finally, the pneumatic gripper 44 releases the workpiece. The transfer cylinder 43 drives the pneumatic gripper 44 to reset upwards, while the lifting cylinder 31 drives the rotary table 33 to move downwards and reset. Under its own gravity, the workpiece slides along the inclined surface of the connecting table 41 from top to bottom and finally enters the feeding end of the second feeding track 102. This allows the axial posture of the workpiece to be automatically corrected before entering the second feeding track 102, eliminating the need for workers to continuously place and load bearing components at the feeding end of the first feeding track 101, thus improving the loading efficiency and posture accuracy of the bearing components.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
