Description

Technical Field

[0001] The present invention relates to the technical field of assembly tooling, and particularly relates to a high-precision angular contact ball bearing assembly tooling. Background Art

[0002] There are three installation forms for angular contact ball bearings, namely back-to-back, face-to-face, and tandem arrangement. When installed back-to-back (the wide end faces of the two bearings are opposite), the contact angle lines of the bearings spread along the axis of rotation, which can increase the radial and axial support angle rigidity, and the anti-deformation ability is the largest. When installed face-to-face (the narrow end faces of the two bearings are opposite), the contact angle lines of the bearings converge towards the axis of rotation, and its support angle rigidity is smaller. Since the inner ring of the bearing extends out of the outer ring, when the outer rings of the two bearings are pressed together, the original clearance of the outer ring is eliminated, and the preload of the bearing can be increased. When installed in tandem arrangement (the wide end faces of the two bearings are in one direction), the contact angle lines of the bearings are in the same direction and parallel, and the two bearings can share the working load in the same direction.

[0003] However, in the actual assembly process of angular contact ball bearings, the pre-centering of the outer ring and the inner ring requires the inner ring to be "placed" into the outer ring, and then the balls are placed and fastened. In this process, the method of centering the inner and outer rings and then placing the balls results in the two not being in the same concentric position, thus affecting the subsequent smooth assembly of the bearing. For this reason, this application proposes a solution. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-precision angular contact ball bearing assembly tooling, which is used to solve the problems of inaccurate centering of the inner and outer rings and inaccurate ball placement during bearing assembly.

[0005] The purpose of the present invention can be achieved by the following technical solutions: A high-precision angular contact ball bearing assembly tooling includes a frame and an embedded control panel. At the bottom of one side of the frame, an assembly component for assembling angular contact ball bearings is installed. The assembly component includes a chassis and an assembly disk rotatably connected through a column. The assembly disk is provided with assembly holes for the cooperation of the outer ring and the inner ring. An inlet component is arranged corresponding to one of the assembly holes. The inlet component includes an outer ring conveyor belt and an inner ring conveyor belt that are respectively arranged at intervals up and down and are used for feeding the outer ring and the inner ring.

[0006] A driving component for intermittently rotating the assembly disk is installed at the bottom of the chassis.

[0007] A ball placement component is arranged on the opposite side of the assembly disk through the inlet component. The ball placement component includes a ball disk and a ball dropping tube. The end of the ball dropping tube corresponds to one of the assembly holes.

[0008] Further set as: The driving assembly includes an intermittent disk coaxially arranged with the assembly disk. The intermittent disk is rotatably installed with a rotating substrate and a driving disk. A shifting lever is installed on the lower surface of the rotating substrate close to the driving disk. A transmission groove matching the shifting lever is formed on the intermittent disk.

[0009] Further set as: An anti-collision groove is formed on the driving disk. The shifting lever is aligned with the middle section of the anti-collision groove. A motor three is arranged on the lower side of the driving disk. A guiding groove matching the arc side of the driving disk is formed on the rotating substrate.

[0010] Further set as: A rotating cylinder is rotatably installed on the outer sides of the middle parts of the chassis and the assembly disk. A supporting mechanism corresponding to the assembly hole is installed at the outer end of the rotating cylinder. The supporting mechanism includes a follower rod connected to the rotating cylinder. A follower support plate is suspended at the outer end of the follower rod.

[0011] Further set as: A plug rod is installed at the outer end of the follower rod. A movable seat is sleeved outside the plug rod. A plurality of springs with the tops connected to the plug rod are installed at the inner bottom of the movable seat. The upper end of the movable seat is connected to the follower support plate.

[0012] Further set as: A guiding ring platform is installed on the outer ring side of the upper surface of the chassis. A multi-curved landslide matching the movable seat is formed on the guiding ring platform. The multi-curved landslide is used for the vertical positioning of the follower support plate.

[0013] Further set as: The multi-curved landslide includes an initial slope, a lifting slope, a conveying slope, an assembly slope, a pressing slope and a reset slope. The initial slope is set corresponding to the outer ring conveyor belt and the inner ring conveyor belt in the feeding assembly. And at this time, the plug rod is at the upper part of the movable seat. As the assembly disk rotates, the movable seat is driven to rotate through the rotating cylinder and the follower rod. Under the lifting action of the lifting slope, the movable seat completes upward movement, that is, the height of the outer and inner rings of the bearing on the follower support plate is lifted.

[0014] Further set as: The bead placing assembly further includes a box body. A bearing plate is installed at the upper end of the box body. A bead dropping hole communicating with the top end of the bead dropping pipe is formed on the bearing plate. A motor one is installed above the middle part of the bearing plate. The output end of the motor one is installed with a bead separating wheel through a rotating rod. A dropping pipe corresponding to the wheel gap of the bead separating wheel is installed at the lower end of the ball disk.

[0015] Further set as: when the assembly disk continues to rotate, it will successively pass through the conveying slope and the assembly slope to reach the ball placing position, and coincide with the outer ring that rotates synchronously with the assembly disk, forming a preliminary assembly effect where the outer ring and the inner ring coincide and are not in a concentric state, facilitating the placement of all the balls. After all the balls are placed, at this time, the assembly disk continues to rotate. When passing through the press-fitting slope, the placement and loading steps of the current cage are completed. Finally, it returns to the initial slope position of the previous sequence through the reset slope, thus completing all the assembly work of a set of angular contact ball bearings.

[0016] Further set as: during the loading process of bearing parts, when the outer ring is conveyed to the assembly disk through the outer ring conveyor belt, the outer ring at this time on the assembly hole is not in a centered state. During the rotation of the assembly disk, the position adjustment is completed through the radial clamping rail according to the position of the outer ring, so as to prepare for the subsequent centering of the inner and outer rings.

[0017] Further set as: the control panel is internally provided with an assembly industrial control module, and the assembly industrial control module includes a positioning monitoring unit, a bead placement risk analysis unit, and a signal execution unit that are communicatively connected;

[0018] The positioning monitoring unit is used to collect the deviation values of the inner and outer rings and the bead placement quantity values during the bearing assembly, and send the deviation values of the inner and outer rings and the bead placement quantity values to the bead placement risk analysis unit. The bead placement risk analysis unit immediately analyzes the assembly radial difference data of the bearing according to the received deviation values of the inner and outer rings and the bead placement quantity values, generates a control signal, and sends the control signal to the signal execution unit to control the operation of the components.

[0019] The present invention has the following beneficial effects:

[0020] 1. The present invention aims at the problems of inaccurate centering of the inner and outer rings and inaccurate ball placement during bearing assembly; on the one hand, through the position limitation of the inner ring and the outer ring and the quantitative ball placement, the combination of the two can ensure that during the bearing assembly process, the assembly is completed by continuously placing the balls based on the synchronous positioning of the outer ring and the inner ring, preventing the phenomena of inaccurate centering of the inner and outer rings and inaccurate ball placement quantity, and improving the bearing assembly efficiency; on the other hand, combined with the intelligent assembly industrial control module, the assembly radial difference data is calculated based on the deviation of the inner and outer rings and the bead placement quantity data, and then the current assembly state of the balls and the inner and outer rings is obtained from the assembly radial difference data and corresponding corrections are made according to the assembly state, so that the assembly work of the angular contact ball bearings proceeds smoothly;

[0021] 2. During the current intelligent control of the placement process of the inner and outer rings and the balls, the product value of the deviation value NCz between the inner and outer rings and the number of dropped balls GZz reflects the accuracy of the current bearing assembly. The current ball placement risk factors can be inversely deduced from the deviation value NCz between the inner and outer rings and the number of dropped balls GZz obtained in real time, and corresponding action guidance can be made according to the ball placement risk factors to conform to normal assembly. Then, action guidance for relevant components can be carried out according to the assembly diameter difference data, so as to ensure the smooth assembly of the angular contact ball bearing.

[0042] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. 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 belong to the scope of protection of the present invention.

[0043] Embodiment 1: Aiming at the problems of inaccurate centering of the inner and outer rings and inaccurate placement of ball bearings during bearing assembly, the following technical solutions are proposed:

[0044] Refer to Figure 1 - Figure 8As shown in the figure, in this embodiment, a high-precision angular contact ball bearing assembly tooling includes a frame 1 and an embedded control panel. At the bottom of one side of the frame 1, an assembly component 3 for assembling angular contact ball bearings is installed. The assembly component 3 includes a chassis 301 and an assembly disk 302 that are rotatably connected through columns. Among them, the chassis 301 is rotatably connected to the columns, and the columns are fixedly connected to the assembly disk 302;

[0045] On the assembly disk 302, there are assembly holes 303 for the cooperation of the outer ring and the inner ring. An inlet component 4 is arranged outside one of the assembly holes 303 on the assembly disk 302. The inlet component 4 includes an outer ring conveyor belt 41 and an inner ring conveyor belt 42 that are respectively arranged at intervals up and down and are used for feeding the outer ring and the inner ring; At the bottom of the chassis 301, a driving component 8 for intermittently rotating the assembly disk 302 is installed;

[0046] The driving component 8 includes an intermittent disk 81 coaxially arranged with the assembly disk 302. A rotating substrate 84 and a driving disk 85 are rotatably installed on the intermittent disk 81. A push rod 87 is installed on the lower surface of the rotating substrate 84 close to the driving disk 85. A transmission groove 82 matching the push rod 87 is opened on the intermittent disk 81. An anti-collision groove 88 is opened on the driving disk 85. The push rod 87 is aligned with the middle section of the anti-collision groove 88. A motor three 86 is arranged on the lower side of the driving disk 85;

[0047] A guiding groove 83 matching the arc side of the driving disk 85 is opened on the rotating substrate 84. When the motor three 86 is started to drive the driving disk 85 to rotate, the driving disk 85 drives the intermittent disk 81 to rotate intermittently through the push rod 87, so as to perform pre-positioning feeding of the bearing outer ring and the bearing inner ring that are synchronously on the assembly component 3 at the same time. After the intermittent rotation is completed, the bearing outer ring and the bearing inner ring can complete the horizontal alignment after non-synchronous feeding;

[0048] On the opposite side of the assembly disk 302 through the inlet component 4, a ball placing component 2 is arranged. The ball placing component 2 includes a ball disk 202 and a ball dropping tube 207. The end of the ball dropping tube 207 corresponds to one of the assembly holes 303. The ball placing component 2 further includes a box body 201. A bearing plate 208 is installed at the upper end of the box body 201. A ball dropping hole communicating with the top end of the ball dropping tube 207 is opened on the bearing plate 208. A motor one 204 is installed above the middle of the bearing plate 208. The output end of the motor one 204 is installed with a bead separating wheel 206 through a rotating rod 205. A falling tube 203 corresponding to the wheel gap of the bead separating wheel 206 is installed at the lower end of the ball disk 202;

[0049] On the outer side of the upper surface of the assembly disk 302 corresponding to the assembly hole 303, a radial clamping rail 304 is installed. The radial clamping rail 304 is arc-shaped and can be adjusted adaptively according to the outer diameter of the bearing outer ring to be assembled, so as to ensure that the outer ring is in the "centered" position, so as to facilitate subsequent stable assembly;

[0050] At the bottom of the frame 1, an equidistant component 5 and a press-fitting component 6 corresponding to the assembly holes 303 are successively installed. After the outer ring and the inner ring are respectively placed, the equidistant component 5 presses down to complete the positioning and separation of the balls between the inner ring and the outer ring, and immediately changes position after equal division, and the cage is assembled and pressed through the press-fitting component 6, so as to ensure the stable installation of the angular contact ball bearing;

[0051] Structural principle: During the assembly process of the angular contact ball bearing, the inner and outer rings are respectively transported and adaptively adjusted according to the outer diameters of the inner and outer rings, and then the pre-assembly of the bearing is completed by intermittently placing the balls. Finally, the cage is loaded on the front and back sides to complete the assembly of the entire angular contact ball bearing. During the assembly process, it can effectively ensure the accurate centering of the inner and outer rings and the stable placement of the balls, and prevent the phenomenon of too many or too few balls being placed;

[0052] The control panel is internally provided with an assembly industrial control module, and the assembly industrial control module includes a positioning monitoring unit, a ball placement risk analysis unit and a signal execution unit that are communicatively connected;

[0053] The positioning monitoring unit is used to collect the deviation values of the inner and outer rings and the number of dropped balls during the bearing assembly, and send the deviation values of the inner and outer rings and the number of dropped balls to the ball placement risk analysis unit. Among them, the deviation value of the inner and outer rings is the inner diameter difference between the bearing outer ring and the bearing inner ring, and is marked as NCz, while the number of dropped balls is expressed as the number of balls between the outer ring and the inner ring of a single group of bearings, and is marked as GZz;

[0054] The ball placement risk analysis unit immediately analyzes the assembly diameter difference data ZJz of the bearing according to the received deviation value NCz of the inner and outer rings and the number of dropped balls GZz. The specific analysis process is as follows: Construct the calculation formula of the assembly diameter difference data ZJz: ZJz = a×NCz + b×GZz, where a > b > 0 are the preset proportionality coefficients of the deviation value of the inner and outer rings and the number of dropped balls respectively;

[0055] Moreover, the deviation value NCz of the inner and outer rings is obtained by taking pictures with a camera vertically arranged above the assembly disk 302 and automatically obtaining the diameter for difference calculation, while the number of dropped balls is measured by a photoelectric sensor arranged in the ball dropping tube 207. The product value of the deviation value NCz of the inner and outer rings and the number of dropped balls GZz reflects the accuracy of the current bearing assembly. The current ball placement risk factors (the deviation of the inner and outer rings or the deviation of the number of dropped balls) can be deduced in reverse from the deviation value NCz of the inner and outer rings and the number of dropped balls GZz obtained in real time, and corresponding action guidance is made according to the ball placement risk factors to conform to the normal assembly. Then, the regulation signal is generated by comparing the assembly diameter difference data with the preset assembly diameter difference threshold in the industrial control module, and the regulation signal is sent to the signal execution unit to control the operation of the components;

[0056] The generation process of the control signal is as follows: If the assembly diameter difference data < the assembly diameter difference threshold, it indicates that there is an assembly omission in the placement of the balls between the inner and outer rings of the current bearing, and a replenishment signal is generated and sent to the first motor 204 and the first electric push rod 51. The first motor 204 starts to drive the ball dividing wheel 206 to rotate, so as to continue to discharge the balls from the ball dropping tube 207 to between the outer ring and the inner ring. The first electric push rod 51 drives the parting fork 52 to move downward to between the inner and outer rings. Under the separation action of the parting fork 52, the balls between the inner and outer rings are separated and fall into the equal positions, and finally stable assembly is achieved.

[0057] If the assembly diameter difference data ≥ the assembly diameter difference threshold, it indicates that the placement of the balls between the inner and outer rings of the current bearing is normal, and no signal is generated.

[0058] Basic principle: During the bearing assembly process, by limiting the positions of the inner and outer rings and making a quantitative placement of the balls, the combination of the two can ensure that the bearing assembly is completed by continuously placing the balls based on the synchronous positioning of the outer and inner rings, preventing the phenomena of inaccurate centering of the inner and outer rings and inaccurate number of placed balls, and improving the bearing assembly efficiency; on the other hand, combined with the intelligent assembly industrial control module, the assembly diameter difference data is calculated based on the deviation between the inner and outer rings and the number of dropped balls, and then the assembly state of the current balls and the inner and outer rings is obtained from the assembly diameter difference data and corresponding corrections are made according to the assembly state, so as to smoothly carry out the assembly work of the angular contact ball bearing.

[0059] Embodiment 2: This embodiment further optimizes the assembly structure in Embodiment 1:

[0060] Refer to Figure 10 As shown, a rotating cylinder 901 is rotatably installed on the outer side of the middle part of the chassis 301 and the assembly disk 302. A support mechanism 9 corresponding to the assembly hole 303 is installed at the outer end of the rotating cylinder 901. The support mechanism 9 includes a follower rod 902 connected to the rotating cylinder 901. A follower support plate 903 is suspended at the outer end of the follower rod 902. A plug rod 905 is installed at the outer end of the follower rod 902, and a movable seat 904 is sleeved outside the plug rod 905;

[0061] A plurality of springs 906 with the tops connected to the plug rod 905 are installed at the inner bottom of the movable seat 904. The upper end of the movable seat 904 is connected to the follower support plate 903. A guiding ring platform 35 is installed on the outer ring side of the upper surface of the chassis 301. A multi-arc landslide adapted to the movable seat 904 is opened on the guiding ring platform 35, and the multi-arc landslide is used for the vertical positioning of the follower support plate 903;

[0062] Refer to Figure 4 - Figure 7As shown in the figure, the multi-radial landslide includes an initial slope 351, a lifting slope 352, a conveying slope 353, an assembling slope 354, a pressing slope 355 and a reset slope 356. The initial slope 351 is set corresponding to the outer ring conveyor belt 41 and the inner ring conveyor belt 42 in the feeding component 4. At this time, the inserting rod 905 is located above the movable seat 904. As the assembling disk 302 rotates, the movable seat 904 is driven to rotate through the rotating cylinder 901 and the follower rod 902. Under the lifting action of the lifting slope 352, the movable seat 904 moves upward, that is, the height of the outer and inner rings of the bearing on the follower support plate 903 is lifted.

[0063] Further, as the assembling disk 302 continues to rotate, it successively passes through the conveying slope 353 and the assembling slope 354 to reach the ball placing position, and coincides with the outer ring that rotates synchronously with the assembling disk 302, forming a preliminary assembling effect where the outer and inner rings coincide, and they are not in a concentric state, which is convenient for all the balls to be placed. After all the balls are placed, at this time, the assembling disk 302 continues to rotate. When passing through the pressing slope 355, the current cage placing and loading steps are completed. Finally, it returns to the position of the previous initial slope 351 through the reset slope 356. Thus, the entire assembling work of a set of angular contact ball bearings is completed.

[0064] Combined with Embodiment 1, during the loading process of the bearing parts, when the outer ring is conveyed to the assembling disk 302 through the outer ring conveyor belt 41, the outer ring at the assembling hole 303 is not in a centered state at this time. During the rotation of the assembling disk 302, the position adjustment is completed through the radial clamping rail 304 according to the position of the outer ring, so as to prepare for the subsequent centering of the outer and inner rings.

[0065] It further includes an equalizing component 5. The equalizing component 5 includes an electric push rod 51 and a splitting fork 52. Through the vertical dropping of the splitting fork 52, the separation and equal clamping of the balls between the outer and inner rings can be realized.

[0066] The pressing component 6 includes an electric push rod 61 and a pressing plate 62. Through the electric push rod 61 driving the pressing plate 62, the clamping after the cage is placed is completed, realizing the common fixation of the outer and inner rings, the balls and the cage, and finally completing the stable assembly of the angular contact ball bearing.

[0067] The pick-up self-inspection 7 includes a plate body 701 connected to the frame 1. A second motor 702 is installed at the rear side of the plate body 701. A swing plate 703 is installed at the front side of the plate body 701 corresponding to the second motor 702. A rotating shaft 704 is rotatably installed at the front end of the swing plate 703. A dropping rod 705 is rotatably installed at the front end of the rotating shaft 704. A horizontally disposed suction cup 706 is installed at the lower end of the dropping rod 705. When the second motor 702 is started, it drives the swing plate 703 to rotate. The swing plate 703 forms a reciprocating "grasping action" through the rotating shaft 704 and the dropping rod 705, thereby realizing the loading after the cage is conveyed, which is beneficial to the subsequent overall assembly of the bearing.

[0068] Embodiment 3: This embodiment combines Embodiment 1 and Embodiment 2 to form an assembly method for an angular contact ball bearing, including the following steps:

[0069] Step 1: The inner ring and the outer ring are respectively conveyed through the inner ring conveyor belt 41 and the outer ring conveyor belt 42. The inner ring is placed on the follower support plate 903, and the outer ring is placed on the assembly hole 303 of the assembly disk 302.

[0070] Step 2: When the third motor 86 is started, it drives the drive disk 85 to rotate. The drive disk 85 drives the intermittent disk 81 to rotate intermittently through the lever 87, thereby feeding the bearing outer ring and the bearing inner ring that are synchronously on the assembly component 3 for pre-alignment. After the intermittent rotation is completed, the bearing outer ring and the bearing inner ring can complete non-synchronous feeding and then be horizontally aligned within the assembly hole 303.

[0071] Step 3: The balls in the ball disk 202 fall into the space between the ball dividing wheels 206 through the falling pipe 203. Under the driving action of the first motor 204 on the ball dividing wheels 206, the balls are intermittently moved into the falling pipe 207 through the ball falling holes on the bearing plate 208, and finally the balls are intermittently replenished and replenished according to the quantity.

[0072] Step 4: The balls replenished between the inner ring and the outer ring are continuously separated and positioned by the downward pressure of the equalizing component 5. After equalization, they are immediately displaced and the cage is assembled and pressed by the press-fitting component 6 and the pick-up component 7, thereby ensuring the stable installation of the angular contact ball bearing.

[0073] In summary: On the one hand, by separately conveying the inner and outer rings and making adaptive adjustments according to the outer diameters of the inner and outer rings, and then pre-assembling the bearing by intermittently placing the balls, and finally loading the cage on both sides to complete the assembly of the entire angular contact ball bearing. During the assembly process, it can effectively ensure the accurate centering of the inner and outer rings and the stable placement of the balls, preventing the phenomenon of too many or too few balls being placed.

[0074] On the other hand, by means of intelligent assembly of industrial control modules, the assembly diameter difference data is calculated based on the inner and outer ring deviation and the number of falling balls, and then the current assembly state of the ball and the inner and outer rings is obtained from the assembly diameter difference data, and corresponding corrections are made according to the assembly state, so as to ensure the smooth progress of the assembly work of angular contact ball bearings.

[0075] The above formulas are all obtained by collecting a large amount of data for software simulation and selecting a formula close to the true value. The coefficients in the formulas are set by those skilled in the art according to the actual situation.
