Description

Technical Field

[0001] The present invention relates to the technical field of bearing processing, and specifically to a continuous feeding structure based on the assembly of double-row angular contact ball bearings. Background Art

[0002] With the development of industrial automation and the increasing market demand for bearing products, enterprises need to produce more double-row angular contact ball bearings per unit time. The continuous feeding structure can achieve the uninterrupted supply of bearing parts, enabling the assembly equipment to work continuously. For example, in the automotive manufacturing industry, double-row angular contact ball bearings are widely used in automotive wheel hubs. To meet the high-efficiency requirements of the automotive production line, the continuous feeding bearing assembly equipment is particularly important.

[0003] Continuous feeding can make the bearing assembly process more stable. During intermittent feeding, factors such as the impact force of each feeding and the initial position of the parts may vary. However, continuous feeding can precisely control and convey bearing parts at a uniform speed and stable posture, thereby improving the assembly accuracy. Taking the double-row angular contact ball bearings in high-precision machine tools as an example, their assembly accuracy directly affects the machining accuracy of the machine tools, and continuous feeding helps to ensure such high-precision requirements;

[0004] It should be noted in combination with the above content that the Chinese patent with the publication number CN218490837U discloses an automatic feeding device for bearing assembly, which grabs the inner and outer rings of the bearing through a clamping mechanism. The clamping plate of this structure has a large stroke and can clamp and feed the inner and outer rings of bearings with different inner diameters. In fact, during actual operation, the grabbing and transportation stroke of the inner and outer rings of the bearing is too large. Along with the wear between mechanical structures, connection deviations, and the grabbing adjustment for the inner and outer ring bearings, all may lead to changes in the feeding trajectory after clamping, thus causing abnormalities in the subsequent assembly of the inner and outer rings of the bearing and other accessories.

[0005] In view of the above technical defects, a solution is now proposed. Summary of the Invention

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1: Please refer to Figure 1 - Figure 8As shown in the figure, this embodiment is a continuous feeding structure based on the assembly of double-row angular contact ball bearings, including multiple groups of feeding vertical frames 1. An inner conveying belt 101 is arranged on the inner wall of the feeding vertical frame 1. Multiple groups of limit clamps 7 are arranged on the surface of the inner conveying belt 101. A lifting drive frame 4 is arranged on the outer wall of one group of feeding vertical frames 1. A material supporting tray frame 6 close to the inner conveying belt 101 is arranged below the lifting drive frame 4. An assembly tray 5 is arranged below the material supporting tray frame 6. Sleeve distribution frames 2 are symmetrically arranged at both ends of the feeding vertical frame 1. Multiple groups of position adjustment auxiliary frames 3 close to the feeding vertical frame 1 are sleeved on the frame body of the sleeve distribution frame 2.

[0031] The sleeves to be processed are transported by the sleeve distribution frame close to the feeding vertical frame 1. The sleeves to be processed first pass through the limit frame 201 and then approach the position adjustment auxiliary frame 3. When the sleeves to be processed are offset during the movement along the surface of the conveyor belt 202, the outer guide plate 305 is driven by the fine-tuning cylinder, causing the outer guide plate 305 to slide axially along the slide bar close to the inner wall of the frame body of the sleeve distribution frame, ensuring the transportation range of the sleeves to be processed along the conveyor frame.

[0032] A conveyor belt 202 is arranged on the inner wall of the top frame body of the sleeve distribution frame 2. Transmission frames are symmetrically arranged on the outer walls on both sides of the sleeve distribution frame 2.

[0033] A transverse moving beam rod 301 is arranged at the bottom of the position adjustment auxiliary frame 3. A driving cylinder column 302 is sleeved in the middle of the surface of the transverse moving beam rod 301, and the driving cylinder column 302 is clamped with the bottom of the sleeve distribution frame 2. A bent connecting rod 303 is arranged on the inner wall of the top of the position adjustment auxiliary frame 3. An inner plate 304 is arranged on the rod body at the bottom of the bent connecting rod 303. An outer guide plate 305 is arranged on the outer wall of the inner plate 304, and a fine-tuning cylinder and a slide bar are arranged between the inner plate 304 and the outer guide plate 305.

[0034] When waiting for it to approach the outer guide plate 305, the driving cylinder column 302 drives the transverse moving beam rod 301 to slide axially through relevant accessories. Accordingly, the overall multiple groups of position adjustment auxiliary frames 3 move closer to the middle, and the distance between the outer guide plates 305 is gradually reduced, causing the sleeves to be processed located between the multiple outer guide plates 305 on the conveyor belt 202 to be pushed and centered. According to the size of the sleeves to be processed, the fine-tuning cylinder further drives the outer guide plate 305 to slide axially along the slide bar, causing the distance between the outer guide plate 305 and the inner plate 304 to gradually increase, and the sleeves to be processed are further pushed and clamped between the outer guide plates 305. In this state, the conveyor belt 202 pauses rotating. After the position adjustment of the sleeves to be processed is completed, the fine-tuning cylinder drives the outer guide plate 305 to reset, and the conveyor belt 202 further drives the sleeves to be processed to be transported close to the feeding vertical frame 1.

[0035] On the outer wall of the lifting drive frame 4 close to the outer wall of the bushing distribution frame 2, a rotary cylinder 401 is provided. A telescopic cylinder column 402 is sleeved in the middle of the rotary cylinder 401. An adjusting robotic arm 403 is sleeved on the bottom column of the telescopic cylinder column 402. A sleeve 404 connected to the material tray frame 6 is provided on the arm of the adjusting robotic arm 403.

[0036] When the bushing to be processed approaches the feeding vertical frame 1, the lifting drive frame 4 is activated. The lifting drive frame 4 drives the telescopic cylinder column 402 to rotate through the rotary cylinder 401. The telescopic cylinder column 402 drives the adjusting robotic arm 403 and the sleeve 404 to rotate synchronously, causing the socket connection to drive the material tray frame 6 to move closer between the two bushing distribution frames. The telescopic cylinder column 402 further drives the adjusting robotic arm 403 to slide upward;

[0037] Therefore, it drives the material tray frame 6 to slide upward and keep the same height as the conveyor belts 202 on the two bushing distribution frames, and waits for a set of limit clamps 7 at the top of the inner conveyor belt to slide down close. Until the bushing to be processed on the material tray frame 6 is clamped, the lifting drive frame 4 drives the material tray frame 6 to reset away from between the two bushing distribution frames, providing a sliding space for the multiple sets of limit clamps 7 to move downward. After waiting for them to move past, it approaches between the two bushing distribution frames again, constituting a coordinated linkage lifting operation process.

[0038] A jacking cylinder 602 sleeved with the sleeve 404 is provided at the bottom of the material tray frame 6, and the jacking cylinder 602 is sleeved with the bottom shaft of the middle plate frame 601. Multiple elliptical grooves are provided on the top surface of the material tray frame 6, and a traction microbelt 603 is provided in the elliptical grooves. A micro-motor and a lifting cylinder connected to the traction microbelt 603 are provided on the inner wall of the elliptical groove.

[0039] When the conveyor belt 202 continuously conveys the bushing to be processed until it is transported to the top of the material tray frame 6, the lifting cylinder drives the traction microbelt 603 and the micro-motor to slide upward along the inside of the elliptical groove synchronously until the top of the traction microbelt 603 contacts the bottom wall of the bushing to be processed. The micro-motor drives the traction microbelt 603 to rotate through related accessories. The traction microbelt 603 frictions with the bottom of the bushing to be processed. Under the lifting and traction of multiple traction microbelts 603, it causes the bushing to be processed to move closer to the middle plate frame 601. The jacking cylinder 602 drives the middle plate frame 601 to slide upward through the shaft, lifting the bushing to be processed upward, facilitating the clamping and socket connection of the bushing to be processed by the middle arc frame 703 and the side arc frame 702.

[0040] An electric push rod 701 clamped to the surface of the inner conveyor belt 101 is provided on the outer wall of the limit clamp 7. A middle arc frame 703 is provided in the middle of the inner wall of the limit clamp 7. Side arc frames 702 are symmetrically provided at both ends of the middle arc frame 703. Electric push rods 704 connected to the inner wall of the limit clamp 7 are provided on the outer walls of the middle arc frame 703 and the side arc frames 702.

[0041] The feed vertical frame 1 is started by an external servo motor, which drives the internal conveyor belt to rotate along the feed vertical frame 1 through related accessories. A rubber belt is provided inside the internal conveyor belt, and a tooth groove is provided on the inner wall of the rubber belt. The top and bottom inner walls of the feed vertical frame 1 are both provided with toothed transmission rollers connected to the external servo motor. The outside of the internal conveyor belt is composed of multiple groups of metal half-pieces hinged together. The internal conveyor belt is connected to the electric push rod 701 through a fastener, and drives the limit clamp 7 to move stably close to the support tray 6;

[0042] When the limit clamps 7 are waiting to move to the upper sides of the material support plate 6, the electric push rod 1 701 drives the symmetrically suspended limit clamps 7 to move closer to the center. The inner walls of the bottoms of the side arc frames 702 are each provided with a protruding arc plate. In this state, the arc plate is located below the shaft sleeve to be processed that is suspended in the air. The multiple sets of electric push rods 2 704 respectively drive the middle arc frame 703 and the side arc frame 702 to move closer to the shaft sleeve to be processed that is suspended in the air until the middle arc frame 703 and the side arc frame 702 contact the outer wall of the shaft sleeve to be processed.

[0043] A micro electric rotating shaft is provided between the side arc frame 702 and the second electric push rod 704. The micro electric rotating shaft drives the side arc frame 702 to deflect away from one end of the middle arc frame 703 and toward the shaft sleeve to be processed, thereby causing both sides of the shaft sleeve to be processed to be clamped in a covering manner. The second electric push rod 704 connected to the middle arc frame 703 is further activated, which drives the middle arc frame 703 to move further and clamp the shaft sleeve to be processed between the multiple groups of limiting clamps 7, thereby forming a multi-point covering clamping of the outer periphery of the shaft sleeve to be processed and a multi-point lifting contact limiting of the bottom of the shaft sleeve to be processed;

[0044] The feed vertical frame 1 further drives the limiting fixture 7 to slide down through the internal transmission, and the limiting fixture 7 drives the clamped shaft sleeve to be processed to slide down close to the assembly tray 5. Driven by the assembly equipment, the assembly tray 5 slides up close to the bottom area of the feed vertical frame 1, and cooperates with the limiting fixture 7 to receive the angle of the shaft sleeve to be processed, and places the shaft sleeve to be processed after the limit adjustment on the top of the assembly tray 5;

[0045] During the placement process, multiple sets of side arc frames 702 are first driven away from the shaft sleeve to be processed by the electric push rod 2 704, and the middle arc frame 703 is synchronously retracted by the electric push rod 2 704, and the shaft sleeve to be processed is placed in the top center of the assembly tray 5. The assembly tray 5 is replaced according to the bearing processing needs and is not limited to the style shown in the drawings.

[0046] Embodiment 2: This embodiment is a continuous feeding structure based on the assembly of double-row angular contact ball bearings. A control panel communicatively connected to the assembly equipment is provided on the outer wall of another set of feeding vertical frames 1. A limit frame 201 is provided on the end frame of the bushing distribution frame 2 away from the feeding vertical frame 1, and an optical sensor is provided on the inner wall of the limit frame 201 for collecting the external shape parameter values of the bearing body passing through;

[0047] The top of the material supporting tray frame 6 is sleeved with a middle tray frame 601, and a weighing sensor is embedded at the top of the middle tray frame 601 for collecting the heavy-load floating value of the bearing body passing through, and sending the external shape parameter value and the heavy-load floating value to the database inside the control panel for comparison and analysis. Warning text is generated according to the analysis result and displayed on the control panel, thus constituting a feeding supervision system.

[0048] The feeding supervision system is activated when the bushing to be processed is clamped by an external device and placed on the bushing distribution frame, generates a supervision instruction and sends it to the optical sensor and the weighing sensor, and the optical sensor and the weighing sensor are used to collect data by real-time monitoring of the bushing to be processed passing through;

[0049] The external shape parameter value indicates whether there are abnormal areas such as pits, protrusions, scratches, etc. on the outer surface of the bushing to be processed, and it is marked as the external shape parameter value WZ. The heavy-load floating value indicates the difference generated by comparing the weight of the bushing to be processed with the preset bearing standard weight, and it is marked as the heavy-load floating value CZ. The external shape parameter value WZ and the heavy-load floating value CZ are sent to the database;

[0050] After receiving the external shape parameter value WZ and the heavy-load floating value CZ, the database immediately performs an abnormal risk analysis on this group of bearings through the formula to obtain the abnormal risk coefficient Rf. Among them, q and a are the proportionality coefficients of the external shape parameter value WZ and the heavy-load floating value CZ respectively, q > a > 0. The preset abnormal risk threshold YR pre-stored in the database is retrieved and compared with the abnormal risk coefficient Rf for analysis:

[0051] If the abnormal risk coefficient Rf > the preset abnormal risk threshold YR, it is determined that there is an assembly risk for this group of bearings to be processed, and an alarm signal is generated. The database generates text in the format of "shaft sequence 983 / abnormal re-inspection / shaft sequence marking / configuration adjustment and replacement plan / data record" according to the alarm signal and displays it on the display screen of the control panel, and at the same time sends the displayed text to the display screen of the assembly equipment to remind the operator;

[0052] According to the pre-set adjustment and replacement scheme, after it is started, when the feeding vertical frame 1 holds and slides down the bearings to be processed with detected abnormalities close to the assembly equipment, the assembly equipment stops the upward sliding of the assembly tray 5. The waste shaft recycling equipment arranged on the side of the assembly equipment receives the bearings to be processed that slide down, marks abnormal signals for recycling and processing, while the feeding vertical frame 1 continues to operate, delivers the next group of normal bearings to be processed close to the assembly equipment, and then the assembly equipment starts the assembly tray 5 to dock with it;

[0053] If the abnormal risk coefficient Rf < the preset abnormal risk threshold YR, no signal is generated.

[0054] Combined with the first and second embodiments, it can be seen that the present invention has many innovative designs around the feeding of the bushing. The position adjustment auxiliary frame 3 operates in coordination with the fine adjustment cylinder and the driving cylinder column 302, accurately centers according to the condition of the bushing, and reduces processing errors; the lifting linkage uses multiple components to realize the adaptation and reset of the material tray rack 6 and the distribution rack, and cooperates with the limit fixture 7 to ensure efficient and reliable material transfer. The feeding vertical frame 1 cooperates with the internal conveyor belt and others to realize the stable clamping and smooth conveying of the bushing to the assembly tray 5.

[0055] The feeding supervision system integrates sensors to monitor the appearance and weight, analyzes risks in the database, alarms and adjusts the configuration and replacement in case of abnormalities, and uses the recycling equipment to ensure the continuity of the process and improve the qualification rate.

The preferred embodiments do not describe all the details in detail, nor do they limit the present invention to the specific embodiments only. Obviously, many modifications and changes can be made according to the content of this specification.
