Description

Technical Field

[0001] The invention relates to the technical field of bearing processing, in particular 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, companies need to produce more double-row angular contact ball bearings per unit time. The continuous loading structure can achieve an uninterrupted supply of bearing parts, allowing assembly equipment to work continuously. For example, in the automobile manufacturing industry, double-row angular contact ball bearings are widely used in automobile hub units. In order to meet the high-efficiency requirements of automobile production lines, continuous loading bearing assembly equipment is particularly important.

[0003] Continuous loading can make the bearing assembly process more stable. In the intermittent loading process, the impact force of each loading, the initial position of the parts and other factors may be different, while continuous loading can improve the assembly accuracy by precisely controlling the conveying of bearing parts at a uniform speed and in a stable posture. Take the double-row angular contact ball bearings in high-precision machine tools as an example. The assembly accuracy directly affects the machining accuracy of the machine tools. Continuous loading helps to ensure this high-precision requirement.

[0004] In conjunction with the above content, it should be explained that: Chinese patent with announcement 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 stroke of this structure is large, and the inner and outer rings of bearings with different inner diameters can be clamped and fed; in fact, during actual operation, the grasping and transportation stroke of the inner and outer rings of the bearing is too large, accompanied by wear between the mechanical structures, connection deviations, and grasping adjustments for the inner and outer ring bearings, which may lead to changes in the feeding trajectory after clamping, thereby causing abnormalities in the subsequent assembly of the inner and outer rings of the bearing and other accessories.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figure 1 - Figure 8As shown, this embodiment is a continuous feeding structure based on the assembly of double-row angular contact ball bearings, including multiple groups of feed vertical frames 1, an inner conveyor belt 101 is arranged on the inner wall of the feed vertical frame 1, and multiple groups of limit clamps 7 are arranged on the surface of the inner conveyor belt 101, a group of feed vertical frames 1 is provided with a lifting drive frame 4 on the outer wall, a supporting plate frame 6 close to the inner conveyor belt 101 is arranged below the lifting drive frame 4, and an assembly tray 5 is arranged below the supporting plate frame 6, and shaft sleeve distribution frames 2 are symmetrically arranged at both ends of the feed vertical frame 1, and multiple groups of positioning auxiliary frames 3 close to the feed vertical frame 1 are sleeved on the frame body of the shaft sleeve distribution frame 2.

[0031] The shaft sleeve to be processed is transported to the feed vertical rack 1 through the shaft sleeve distribution rack. The shaft sleeve to be processed first passes through the limit rack 201 and approaches the positioning auxiliary rack 3. When the shaft sleeve to be processed is offset during its movement along the surface of the conveyor belt 202, the outer guide plate 305 is driven by the fine-tuning cylinder to cause the outer guide plate 305 to slide axially along the slide rod close to the inner wall of the frame of the shaft sleeve distribution rack, thereby ensuring that the shaft sleeve to be processed is within the transportation range along the conveyor rack.

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

[0033] A transverse beam 301 is provided at the bottom of the positioning auxiliary frame 3, a driving cylinder column 302 is sleeved on the middle part of the surface of the transverse beam 301, and the driving cylinder column 302 is clamped with the bottom of the sleeve distribution frame 2, a bent connecting rod 303 is provided on the inner wall of the top of the positioning auxiliary frame 3, an inner plate 304 is provided on the rod body at the bottom of the bent connecting rod 303, an outer guide plate 305 is provided on the outer wall of the inner plate 304, and a fine-tuning cylinder and a sliding rod are provided 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 beam 301 to slide axially through the relevant accessories, thereby the overall multiple groups of positioning auxiliary frames 3 move closer to the center, and the spacing between the outer guide plates 305 is gradually reduced, causing the shaft sleeves to be processed between the multiple groups of outer guide plates 305 on the conveyor belt 202 to be pushed and centered. According to the size of the shaft sleeves to be processed, the fine-tuning cylinder further drives the outer guide plate 305 to slide axially along the slide rod, causing the spacing between the outer guide plate 305 and the inner plate 304 to increase step by step, and the shaft sleeves to be processed are further pushed and clamped between the outer guide plates 305. In this state, the conveyor belt 202 stops rotating, waiting for the position adjustment of the shaft sleeves to be processed to be completed, the fine-tuning cylinder drives the outer guide plate 305 to reset, and the conveyor belt 202 further drives the shaft sleeves to be processed to be transported close to the feed vertical frame 1.

[0035] A rotary cylinder 401 is arranged on the outer wall of the lifting drive frame 4 close to the sleeve distribution frame 2, a telescopic cylinder column 402 is sleeved in the middle of the rotary cylinder 401, an adjusting mechanical arm 403 is sleeved on the bottom column of the telescopic cylinder column 402, and a sleeve frame 404 connected to the supporting tray frame 6 is arranged on the arm rod of the adjusting mechanical arm 403.

[0036] When the shaft sleeve to be processed is close to the feeding vertical frame 1, the lifting driving frame 4 is started, and the lifting driving frame 4 drives the telescopic cylinder column 402 to rotate through the rotary cylinder 401, and the telescopic cylinder column 402 drives the adjusting mechanical arm 403 and the sleeve frame 404 to rotate synchronously, so that the sleeve connection drives the supporting plate frame 6 to move close to the two sets of shaft sleeve distribution frames, and the telescopic cylinder column 402 further drives the adjusting mechanical arm 403 to slide upward;

[0037] Therefore, the material support rack 6 is driven to slide up and keep it at the same height as the conveyor belts 202 on the two sets of sleeve delivery racks, and wait for a set of limit clamps 7 to slide down and approach the top of the inner conveyor belt until the sleeve to be processed on the material support rack 6 is clamped. Then, the lifting drive frame 4 drives the material support rack 6 to reset away from the two sets of sleeve delivery racks, providing space for multiple sets of limit clamps 7 to slide down, and wait for them to move past, and then approach the two sets of sleeve delivery racks again, forming a coordinated linkage lifting operation process.

[0038] A lifting cylinder 602 is provided at the bottom of the supporting disc frame 6 and is sleeved with the sleeve frame 404, and the lifting cylinder 602 is sleeved with the bottom shaft rod of the middle disc frame 601. A plurality of groups of elliptical grooves are provided on the top surface of the supporting disc frame 6, and a traction microbelt 603 is provided in the elliptical groove, and a micromotor and a lifting cylinder connected to the traction microbelt 603 are provided on the inner wall of the elliptical groove.

[0039] The conveyor belt 202 continues to convey the shaft sleeve to be processed until it is transported to the top of the supporting disc frame 6. The lifting cylinder drives the traction microbelt 603 and the micromotor to slide up along the inside of the elliptical groove synchronously until the top of the traction microbelt 603 contacts the bottom wall of the shaft sleeve to be processed. The micromotor drives the traction microbelt 603 to rotate through relevant accessories. The traction microbelt 603 rubs against the bottom of the shaft sleeve to be processed, and under the support and traction of multiple groups of traction microbelts 603, the shaft sleeve to be processed is moved close to the middle disc frame 601. The lifting cylinder 602 drives the middle disc frame 601 to slide up through the shaft rod, and lifts and slides the shaft sleeve to be processed, so that the middle arc frame 703 and the side arc frame 702 can clamp and connect the shaft sleeve to be processed.

[0040] An electric push rod 1 701 is arranged on the outer wall of the limiting clamp 7 and is clamped with the surface of the inner transmission link 101. A middle arc frame 703 is arranged in the middle of the inner wall of the limiting clamp 7, and side arc frames 702 are symmetrically arranged at both ends of the middle arc frame 703. Electric push rods 2 704 connected to the inner wall of the limiting clamp 7 are arranged 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 inner conveyor belt to rotate along the feed vertical frame 1 through related accessories. A rubber belt is arranged inside the inner conveyor belt, and a tooth groove is arranged 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 outer part of the inner conveyor belt is composed of multiple groups of metal half-pieces hinged. The inner conveyor belt is connected to the electric push rod 701 through a fastener, and drives the limit clamp 7 to stably move close to the support tray frame 6;

[0042] When the waiting limit clamp 7 moves to the upper sides of the supporting plate frame 6, the electric push rod 1 701 drives the symmetrical suspended limit clamp 7 to move closer to the middle, and the inner wall of the bottom of the side arc frame 702 is 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, and multiple groups 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 are in contact with the outer wall of the shaft sleeve to be processed;

[0043] A micro electric rotating shaft is arranged between the side arc frame 702 and the second electric push rod 704, and the micro electric rotating shaft drives the side arc frame 702 to deflect away from one end of the middle arc frame 703 and approach the shaft sleeve to be processed, so as to clamp both sides of the shaft sleeve to be processed in a covering manner, and the second electric push rod 704 connected to the middle arc frame 703 is further started, which drives the middle arc frame 703 to move further, and clamps 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 limit clamp 7 to slide down through the inner conveyor, and the limit clamp 7 drives the clamped shaft sleeve to be processed to slide down close to the assembly tray 5. The assembly tray 5 is driven by the assembly equipment to slide up close to the bottom area of ​​the feed vertical frame 1, and cooperates with the limit clamp 7 to receive the shaft sleeve to be processed at an angle, 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 to place the shaft sleeve to be processed at 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 drawing.

[0046] Embodiment 2: This embodiment is a continuous feeding structure based on the assembly of double-row angular contact ball bearings, including another group of feed vertical frames 1 having a control panel arranged on the outer wall thereof, the sleeve delivery frame 2 having a limit frame 201 arranged on the frame body at one end away from the feed vertical frame 1, and an optical sensor arranged on the inner wall of the limit frame 201 for collecting the external reference value of the bearing body;

[0047] The top of the supporting plate rack 6 is connected to the middle plate rack 601, and a weighing sensor is embedded on the top of the middle plate rack 601 to collect the heavy load floating value passing through the bearing body, and send the external reference value and the heavy load floating value to the database inside the control panel for comparison and analysis, and generate warning text according to the analysis structure and display it on the control panel, thereby forming a material feeding supervision system.

[0048] The feeding monitoring system is started when the sleeve to be processed is clamped by an external device and placed on the sleeve delivery rack, generates a monitoring instruction and sends it to the optical sensor and the weighing sensor, which are used to monitor and collect data of the sleeve to be processed in real time;

[0049] The external shape reference value indicates whether there are abnormal areas such as pits, protrusions, scratches, etc. on the surface of the shaft sleeve to be processed, and it is marked as the external shape reference value WZ. The heavy load floating value indicates the difference between the weight of the shaft sleeve body to be processed and the preset bearing standard weight, and it is marked as the heavy load floating value CZ. The external shape reference value WZ and the heavy load floating value CZ are sent to the database;

[0050] After receiving the external reference value WZ and the heavy load floating value CZ, the database immediately performs an abnormal risk analysis on the group of bearings, using the formula The abnormal risk coefficient Rf is obtained, where q and a are the proportional coefficients of the external reference value WZ and the heavy load floating value CZ, respectively, q>a>0, and the pre-stored preset abnormal risk threshold YR is retrieved from the database for comparison and analysis with the abnormal risk coefficient Rf:

[0051] If the abnormal risk coefficient Rf> the preset abnormal risk threshold YR, it is judged that the group of bearings to be processed has assembly risk, and an alarm signal is generated. The database generates text in the format of "axis sequence 983 / abnormal check / axis sequence mark / adjustment and replacement plan / data record" according to the alarm signal and displays it on the display screen of the control panel. At the same time, the displayed text is sent to the display screen of the assembly equipment to remind the operator;

[0052] The configuration replacement scheme is set in advance. After it is started, the feed vertical frame 1 will detect the abnormal bearing to be processed and clamp it to slide down close to the assembly equipment. The assembly equipment stops the upward sliding of the assembly tray 5. The waste shaft recovery equipment set on the side of the assembly equipment will receive the sliding bearing to be processed and mark it with an abnormal signal for recycling. The feed vertical frame 1 continues to operate and delivers the next group of normal bearings to be processed close to the assembly equipment. The assembly equipment then starts the assembly tray 5 to dock with it.

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

[0054] It can be seen from the combination of Example 1 and Example 2 that the present invention has many innovative designs around the processing and feeding of sleeves. The positioning auxiliary frame 3 cooperates with the fine-tuning cylinder and the driving cylinder column 302 to accurately calibrate according to the condition of the sleeve to reduce processing errors. The lifting linkage uses multiple components to achieve the adaptation and resetting of the supporting plate frame 6 and the distribution frame, and cooperates with the limit clamp 7 to ensure efficient and reliable material transfer. The vertical feed frame 1 cooperates with the internal transmission linkage to achieve stable clamping of the sleeve and smooth transportation to the assembly tray 5.

[0055] The feeding supervision system integrates sensors to monitor appearance and weight, analyzes risks through the database, issues alarms and adjusts for replacement when abnormalities occur, and uses recycling equipment to ensure process continuity and improve the pass rate.

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