Description

Technical Field

[0001] This utility model relates to the field of bearing ball-assembly cage technology, specifically a fully automatic water pump bearing servo ball-assembly cage machine. Background Technology

[0002] A cage is a bearing component that partially encloses all or part of the rolling elements and moves with them. It is used to isolate the rolling elements and usually also guides and holds them within the bearing. Installing a cage is the next step after installing the balls in the bearing.

[0003] However, the existing method of pressing down on one side to install the upper and lower cages inside the bearing is prone to situations where the lower cage is subjected to greater force while the upper cage is subjected to less force, thus affecting the installation quality of the cages. Moreover, it can only complete the pressing assembly of the bearing after the cages are installed, which has a limited scope of application.

[0004] As disclosed in Chinese Patent CN221958026U, an automatic bearing cage installation mechanism switches the position of the mounting seat and positioning pin on the bearing by means of the telescopic end of the second electric push rod. After the fixed plate is moved upward by the third electric push rod, the balls between the inner and outer rings of the bearing can be arranged at equal intervals under the action of the positioning pin. When the mounting seat is located under the bearing, after the fixed plate is moved upward by the third electric push rod, it can cooperate with the pressing assembly to complete the pressing assembly of the upper and lower cages on the bearing. By applying pressure to the bearing from both sides at the same time, the assembly accuracy of the upper and lower cages on the bearing can be guaranteed, and the automatic pressing assembly of the upper and lower cages on the bearing can be completed.

[0005] However, during the assembly process using this mounting mechanism, after one bearing is assembled, the assembled bearing needs to be removed and then the bearing cage and bearing to be assembled need to be placed back on for assembly. This results in the mounting mechanism being unable to continuously assemble the bearing cage, leading to low installation efficiency.

[0006] Therefore, we urgently need to provide a fully automatic servo ball-assembly cage machine for continuously assembling water pump bearings. Utility Model Content

[0007] The purpose of this invention is to provide a fully automatic servo ball-loading and retaining machine for water pump bearings, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic water pump bearing servo ball-mounting and retaining machine, including a worktable and support columns. The support columns are fixedly connected to the four corners of the lower side of the worktable. A first motor is installed on the lower right side of the worktable, and a first rotating rod is fixedly connected to the upper end of the output shaft of the first motor. A second motor is installed on the lower left side of the worktable, and a second rotating rod is fixedly connected to the upper end of the output shaft of the second motor. An installation mechanism is connected to the upper end of the worktable.

[0009] The mounting mechanism includes a first turntable fixedly connected to the upper end of a first rotating rod. A cylinder is fixedly connected to the lower side of the first turntable in an arc shape. A first cylinder is fixedly connected to the bottom inner side of the cylinder. A top plate is fixedly connected to the upper end of the output shaft of the first cylinder. An arc-shaped limiting plate is fixedly connected to the upper side of the first turntable. A second turntable is fixedly connected to the upper end of a second rotating rod. A fixing ring is fixedly connected to the inside of the second turntable in an arc shape. A spring is connected inside the fixing ring. A ball bearing is fixedly connected to one end of the spring. A first support frame is fixedly connected to the upper right end of the worktable. A second cylinder is mounted on the upper end of the first support frame. A circular plate is fixedly connected to the lower end of the output shaft of the second cylinder. A ball-distributing rod is fixedly connected to the lower side of the circular plate. A second support frame is fixedly connected to the middle position of the upper rear end of the worktable. A third cylinder is mounted on the upper front end of the second support frame. A pressure plate is fixedly connected to the lower end of the output shaft of the third cylinder.

[0010] A further improvement is that a circular hole is provided inside the first turntable above the cylinder, and an arc-shaped limiting plate is symmetrically provided on the upper side of the first turntable to the circular hole. The inner side of the arc-shaped limiting plate is slidably connected to the outer side of the bearing outer ring, and the position on the upper side of the first turntable between the edge of the circular hole and the inner side of the arc-shaped limiting plate abuts against the lower side of the bearing outer ring. Thus, when assembling the bearing cage, the inner and outer rings of the bearing containing balls can be placed between the arc-shaped limiting plates on the upper side of the worktable.

[0011] A further improvement is that the ball-splitting rod passes between the inner and outer rings of the bearing on the upper side of the first turntable, thereby allowing the balls between the inner and outer rings of the bearing to be evenly separated by moving the ball-splitting rod between them.

[0012] A further improvement is that the outer side of the top plate is slidably connected to the inner side of the cylinder and the inner side of the circular hole inside the first turntable, so that by activating the first cylinder, the top plate is moved upward, which can drive the lower retainer placed on it to move to the lower inner end of the bearing.

[0013] A further improvement is that a circular groove with equal arc is opened inside the fixed ring. The end of the spring away from the sliding ball is fixedly connected to the innermost end of the circular groove. The outer side of the sliding ball is slidably connected to the inner side of the circular groove. The upper outer end of the part of the sliding ball outside the circular groove abuts against the lower side of the upper retainer placed inside the fixed ring. The outer side of the pressure plate is slidably connected to the inner side of the fixed ring. The lower side of the pressure plate abuts against the upper side of the upper retainer. Thus, by activating the third cylinder and moving its output shaft downward, the pressure plate is moved down to the inner side of the fixed ring, which can press down the upper retainer in the fixed ring.

[0014] A further improvement is that a parts box is connected to the left end of the workbench, and a storage box is connected to the right end of the workbench. An L-shaped rod is fixedly connected to the upper right end of the parts box and the upper left end of the storage box. Sliding holes are opened at both ends of the workbench. The outer side of the L-shaped rod away from the parts box and the storage box is slidably connected to the inner side of the sliding hole. Thus, after the L-shaped rod at the outer end of the parts box and the storage box is slid to the inner side of the sliding hole, the parts box and the storage box can be installed at the left and right ends of the workbench.

[0015] A further improvement is that a support plate is fixedly connected to the upper side of the worktable at the front and rear ends of the lower side of the first and second turntables. A limit sleeve is fixedly connected to the upper end of the support plate. The outer edges of the first and second turntables are slidably connected to the inner side of the limit sleeve, so that the outer edges of the first and second turntables are supported and limited by the limit sleeve.

[0016] In summary, this application discloses a fully automatic servo-driven ball-mounting cage machine for water pump bearings.

[0017] This technical solution involves placing the lower bearing cage above the top plate inside the cylinder, then placing the inner and outer rings of the bearing (containing internal balls) between the arc-shaped limiting plate on the upper side of the first turntable. Next, the upper bearing cage is placed on the sliding balls inside the fixed ring. Then, the first and second motors are activated, causing the first and second turntables to rotate. When the inner and outer rings of the bearing on the first turntable rotate to below the second cylinder, the output shaft of the second cylinder is activated, moving the circular plate downwards and causing the ball separator rod to move downwards as well. This evenly separates the balls between the inner and outer rings of the bearing. The ball separator rod is then raised again, and the first cylinder is activated, moving the lower cage at the top of the top plate upwards to below the space between the inner and outer rings of the bearing. It then rotates to below the third cylinder, which is activated, causing its output shaft to move downwards, moving the pressure plate downwards. After reaching the inner side of the retaining ring, the upper cage inside is pushed down, and the sliding balls are squeezed into the circular groove until they are completely inside. The upper cage slides down to the upper part between the inner and outer rings of the lower bearing. As the pressure plate moves down, the upper cage is pressed down, and the first cylinder is activated again to press the lower cage up. This compresses the upper and lower cages between the inner and outer rings of the bearing, completing the ball separation and cage installation. Then, as the next bearing to be assembled rotates to the bottom of the third cylinder, the assembled bearing rotates to the position in front of the second turntable. At this time, the bearing at the top of the circular hole is removed, and the bearing parts to be assembled are placed back on. This allows the loading and unloading of bearing parts to be carried out simultaneously during the cage installation process, ensuring continuous bearing assembly and improving bearing assembly efficiency.

[0018] Furthermore, after sliding the L-shaped rods at the outer ends of the parts box and storage box to the inside of the sliding hole, the parts box and storage box can be installed at the left and right ends of the workbench, so that workers can easily take out bearing assembly parts and store assembled bearings.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-8 The present invention provides a technical solution: a fully automatic water pump bearing servo ball-mounting and retaining machine, including a worktable 1 and a support column 2. The support column 2 is fixedly connected to the four corners of the lower side of the worktable 1. A first motor 3 is installed on the lower right side of the worktable 1. A first rotating rod 4 is fixedly connected to the upper end of the output shaft of the first motor 3. A second motor 5 is installed on the lower left side of the worktable 1. A second rotating rod 6 is fixedly connected to the upper end of the output shaft of the second motor 5. An installation mechanism is connected to the upper end of the worktable 1.

[0030] The mounting mechanism includes a first turntable 701 fixedly connected to the upper end of the first rotating rod 4. A cylinder 702 is fixedly connected to the lower side of the first turntable 701 with an equal arc. A first cylinder 703 is fixedly connected to the bottom inner side of the cylinder 702. A top plate 704 is fixedly connected to the upper end of the output shaft of the first cylinder 703. An arc-shaped limiting plate 705 is fixedly connected to the upper side of the first turntable 701. A circular hole is opened inside the first turntable 701 above the cylinder 702. The arc-shaped limiting plate 705 on the upper side of the first turntable 701 is symmetrically opened to the circular hole. The inner side of the arc-shaped limiting plate 705 is slidably connected to the outer side of the bearing outer ring. The position of the upper side of the first turntable 701 between the edge of the circular hole and the inner side of the arc-shaped limiting plate 705 abuts against the lower side of the bearing outer ring. Thus, when assembling the bearing cage, the inner and outer rings of the bearing containing balls can be placed between the arc-shaped limiting plates 705 on the upper side of the worktable 1.

[0031] The upper end of the second rotating rod 6 is fixedly connected to the second turntable 706. The interior of the second turntable 706 is fixedly connected to the fixed ring 707 with equal arc. The interior of the fixed ring 707 is connected to the spring 708. One end of the spring 708 is fixedly connected to the ball bearing 709. The upper right end of the worktable 1 is fixedly connected to the first support frame 710. The upper end of the first support frame 710 is equipped with the second cylinder 711. The lower end of the output shaft of the second cylinder 711 is fixedly connected to the circular plate 712. The lower side of the circular plate 712 is fixedly connected to the ball separator 713. The ball separator 713 passes between the inner and outer rings of the bearing on the upper side of the first turntable 701. By moving the ball separator 713 between the inner and outer rings of the bearing, the balls between the inner and outer rings of the bearing can be evenly separated.

[0032] The outer side of the top plate 704 is slidably connected to the inner side of the cylinder 702 and the inner side of the circular hole inside the first turntable 701. Thus, by activating the second cylinder 711, the circular plate 712 moves downward, causing the ball separator 713 to move downward between the inner and outer rings of the bearing between the lower arc-shaped limiting plate 705. After the balls between the inner and outer rings are evenly separated, the top plate 704 is then moved upward by activating the first cylinder 703, which can move the lower retainer placed on it to the lower inner end of the bearing.

[0033] A second support frame 714 is fixedly connected to the middle position of the upper rear end of the worktable 1. A third cylinder 715 is installed at the upper front end of the second support frame 714. A pressure plate 716 is fixedly connected to the lower end of the output shaft of the third cylinder 715. A circular groove with equal arc is opened inside the fixed ring 707. The end of the spring 708 away from the sliding ball 709 is fixedly connected to the innermost end of the circular groove. The outer side of the sliding ball 709 is slidably connected to the inner side of the circular groove. The upper outer end of the part of the sliding ball 709 outside the circular groove abuts against the lower side of the upper retainer placed inside the fixed ring 707. The outer side of the pressure plate 716 is slidably connected to the inner side of the fixed ring 707. The lower side of the pressure plate 716 abuts against the upper side of the upper retainer. Thus, by starting the third cylinder 715, its output shaft moves down, causing the pressure plate 716 to move down to the inner side of the fixed ring 707, which can press down the upper retainer in the fixed ring 707.

[0034] A parts box 8 is connected to the left end of the workbench 1, and a storage box 9 is connected to the right end of the workbench 1. An L-shaped rod 10 is fixedly connected to the upper right end of the parts box 8 and the upper left end of the storage box 9. Sliding holes are provided at the left and right ends inside the workbench 1. The outer side of the L-shaped rod 10 away from the parts box 8 and the storage box 9 is slidably connected to the inner side of the sliding hole. Thus, after the L-shaped rod 10 at the outer end of the parts box 8 and the storage box 9 is slid to the inner side of the sliding hole, the parts box 8 and the storage box 9 can be installed at the left and right ends of the workbench 1, so that the workers can take out the bearing assembly parts and store the assembled bearings.

[0035] A support plate 11 is fixedly connected to the upper side of the worktable 1 at the front and rear ends of the lower side of the first turntable 701 and the second turntable 706. A limit sleeve 12 is fixedly connected to the upper end of the support plate 11. The outer edges of the first turntable 701 and the second turntable 706 are slidably connected to the inner side of the limit sleeve 12, so that the outer edges of the first turntable 701 and the second turntable 706 are supported and limited by the limit sleeve 12, ensuring the stability of the rotation of the first turntable 701 and the second turntable 706.

[0036] Working principle: When assembling the water pump bearing, first place the lower bearing cage to be assembled above the top plate 704 in the cylinder 702. Then, place the inner and outer rings of the bearing with internal balls between the arc-shaped limiting plate 705 on the upper side of the first turntable 701. Next, place the upper bearing cage on the sliding ball 709 inside the fixing ring 707. Then, start the first motor 3 to make the first turntable 701 rotate. When the inner and outer rings of the bearing on the first turntable 701 rotate to below the second cylinder 711, start the second cylinder 711. Its output shaft moves and drives the circular plate 712 to move down, causing the ball separator 713 to move down as well, evenly separating the balls between the inner and outer rings of the bearing. Then, lift the ball separator 713 again and start the first cylinder 703, which drives the top plate 704. The upper lower cage moves upward to below the space between the inner and outer rings of the bearing. Then, the first motor 3 and the second motor 5 are started, causing the bearing after ball separation and the retaining ring 707 with the upper cage to rotate to below the third cylinder 715. Then, the third cylinder 715 is started, and its output shaft moves downward, causing the pressure plate 716 to move downward. After moving to the inside of the retaining ring 707, the upper cage inside it is pushed down, and at the same time, the sliding ball 709 is squeezed into the circular groove until the sliding ball 709 is completely in the circular groove. The upper cage slides down to above the space between the inner and outer rings of the lower bearing. As the pressure plate 716 moves down, it presses the upper cage down. At the same time, the first cylinder 703 is started again to press the lower cage up, pressing the upper and lower cages tightly between the inner and outer rings of the bearing, completing the ball separation of the bearing and the installation of the cage.
