Description

Technical Field

[0001] This utility model belongs to the field of bearing assembly technology, and more specifically, it relates to a thrust bearing ball feeding device. Background Technology

[0002] Thrust bearings consist of two sets of bearing outer rings, cages, and balls. Manual loading is inefficient. Generally, a loading device automatically loads the balls into the thrust bearing and automatically positions and installs them. Conventional feeding devices use pneumatic conveying to automatically stack the balls so that they fall naturally into the cage.

[0003] Based on the above, the current feeding devices lack a feeding structure that can individually position and advance each ball, making it inconvenient to quickly transport and position the ball, as well as a corresponding structure to maintain the fixed bearing and adjust the angle. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a thrust bearing ball feeding device, which solves the problems mentioned in the background art regarding the lack of a feeding structure for individually positioning and advancing each ball, making rapid delivery and positioning inconvenient, as well as the lack of a corresponding structure for maintaining and fixing the bearing and adjusting the angle.

[0005] The purpose and effect of this utility model's thrust bearing ball feeding device are achieved through the following specific technical means:

[0006] A thrust bearing ball feeding device includes a main worktable with a through slot in the middle and a rotary table fixedly mounted on the top center of the main worktable. A bearing mounting seat is rotatably mounted on the top of the rotary table to accommodate the bearing. A worm gear is fixedly mounted on the outer side of the bottom shaft of the bearing mounting seat, and a transmission worm is rotatably mounted on one side of the top of the rotary table, with the transmission worm connected to the worm gear. A servo motor is fixedly mounted on the top of the main worktable and is connected to the transmission worm. Two sets of vertical guide frames are fixedly mounted on the rear top of the main worktable, with an electric cylinder A fixedly mounted in the middle of the vertical guide frames. A drive slider is fixedly mounted on the telescopic end of the electric cylinder A, and the drive slider slides between the two sets of vertical guide frames. A feeding hopper has a tubular bottom structure, and a control chamber is integrally mounted on the rear side of the tubular structure, with the control chamber fixed to the top of the drive slider.

[0007] Furthermore, six sets of micro electric cylinders are fixedly installed at the top center of the bearing mounting base, and positioning blocks are fixedly installed at the telescopic ends of the micro electric cylinders.

[0008] Furthermore, two sets of slip rings are fixedly installed on the lower end of the bearing mounting base, and a brush for supplying power to the slip rings is installed in the middle of the bottom of the main worktable.

[0009] Furthermore, both sides of the lower part of the feeding hopper are integrally provided with side positioning chambers, and limit wedges are slidably provided in the side positioning chambers. The limit wedges cooperate with the spring rod to limit the sliding within the side positioning chambers, with the inclined surface of the limit wedges facing upward.

[0010] Furthermore, an opening is provided at the lower front end of the feeding hopper, and the width of the opening is smaller than the diameter of the tubular structure at the lower end of the feeding hopper.

[0011] Furthermore, an electric cylinder B is fixedly installed on the rear side of the control compartment, and a wedge block is fixedly installed on the telescopic end of the electric cylinder B, which can fit through the opening.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The bearing mounting base provides a rapid feeding and positioning function. The bearing base ring and cage are placed on top of the bearing mounting base, and the micro-electric cylinder is activated to extend the positioning block, thus fixing the bearing. The servo motor is then activated to drive the transmission worm gear to rotate, which in turn drives the worm wheel to rotate, feeding the bearing mounting base to one station. The feeding is completed by using brushes for power supply, which ensures the rotation function while keeping the bearing fixed.

[0014] The feeding hopper provides the function of feeding and filling each ball. The electric cylinder B is activated to push the wedge block forward, causing the wedge block to move into the passage. During this process, the wedge block presses down on the bottom ball, feeding the ball downward and discharging it. The ball then falls into the bearing cage. Alternatively, if it is necessary to directly fill the bearing into the cage horizontally and vertically, the bottom of the feeding hopper is raised so that it is slightly lower than the limit wedge block. This allows the ball to directly enter the cage after it opens the limit wedge blocks on both sides.

[0015] The feeding hopper can be raised and lowered to facilitate the disassembly and assembly of bearings. After a complete set of bearings is loaded, the electric cylinder A is activated to raise the drive slider, lifting the feeding hopper. Then, the micro electric cylinder is retracted to remove the bearings and reinstall them. The drop height can be adjusted according to the thickness of the outer ring of the bearing.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0024] Example 1: As shown in the attached document Figure 1 To be continued Figure 5 As shown:

[0025] This utility model provides a thrust bearing ball feeding device, including a main worktable 1, with a through groove in the middle of the main worktable 1, and a rotary table 2 fixedly installed at the top center of the main worktable 1; a bearing mounting seat 4 is rotatably installed on the top of the rotary table 2 to cooperate with the bearing; a worm gear 403 is fixedly installed on the outside of the bottom rotating shaft of the bearing mounting seat 4, and a transmission worm 201 is rotatably installed on one side of the top of the rotary table 2, and the transmission worm 201 is connected to the worm gear 403; a servo motor 3 is fixedly installed on the top of the main worktable 1, and the servo motor 3 is connected to the transmission worm 201; two sets of vertical guide frames 5 are fixedly installed on the rear side of the top of the main worktable 1, an electric cylinder A6 is fixedly installed in the middle of the vertical guide frames 5, and a drive slider 601 is fixedly installed at the telescopic end of the electric cylinder A6, and the drive slider 601 slides between the two sets of vertical guide frames 5; a feeding hopper 7, the bottom of the feeding hopper 7 is a tubular structure, and a control chamber 701 is integrally installed on the rear side of the tubular structure, and the control chamber 701 is fixed on the top of the drive slider 601.

[0026] Among them, six sets of micro electric cylinders 401 are fixedly installed in the middle of the top of the bearing mounting base 4, and positioning blocks 402 are fixedly installed on the telescopic ends of the micro electric cylinders 401.

[0027] Two sets of electric slip rings are fixedly installed on the lower end of the shaft of the bearing mounting seat 4, and a brush for supplying power to the electric slip rings is installed in the middle of the bottom of the main worktable 1.

[0028] Among them, the lower two sides of the feeding hopper 7 are integrally provided with side positioning chambers 702, and the side positioning chambers 702 are slidably provided with limit wedges 703. The limit wedges 703 cooperate with the spring rod to limit the sliding within the side positioning chambers 702, and the inclined surface of the limit wedges 703 faces upward.

[0029] The feed hopper 7 has an opening 704 at its lower front end. The width of the opening 704 is smaller than the diameter of the tubular structure at the lower end of the feed hopper 7, ensuring that the opening 704 will not affect the movement of the balls.

[0030] An electric cylinder B705 is fixedly installed on the rear side of the control compartment 701. A wedge block 706 is fixedly installed on the telescopic end of the electric cylinder B705. The wedge block 706 can fit through the opening 704.

[0031] like Figure 1-5 As shown, the bearing bottom ring and cage are placed above the bearing mounting seat 4. The micro-electric cylinder 401 is activated to extend the positioning block 402 and fix the bearing. Then, the position of the cage is adjusted so that one of its filling parts is aligned with the bottom of the feeding hopper 7. Multiple sets of balls are pre-filled in the feeding hopper 7. The balls fall naturally by gravity and are blocked by the limit wedge 703, stopping their fall. Then, the electric cylinder B705 is activated to push the wedge block 706 forward. The wedge block 706 moves into the through port 704. During this process, the wedge block 706 presses down the bottom ball, feeding the ball downward and discharging it. The ball then falls into the bearing cage. The servo motor 3 is activated to drive the transmission worm gear 201 to rotate. The transmission worm gear 201 drives the worm wheel 403 to rotate, rotating the bearing mounting seat 4 to feed it to one station, completing the feeding process.

[0032] After a complete set of bearings is loaded, start the electric cylinder A6 to raise the drive slider 601, lift the feeding hopper 7, and then retract the micro electric cylinder 401 to remove the bearings and reinstall them.

[0033] Example 2: Based on Example 1, if it is necessary to directly load the bearing into the cage, the bottom of the feeding hopper 7 is raised so that it is slightly lower than the limiting wedge 703. Then, the ball can directly enter the cage after it opens the limiting wedges 703 on both sides.

[0034] Example 3: Based on Example 1, if smaller balls are used, a sleeve can be installed in the middle of the feeding hopper 7 to reduce the inner diameter and ensure the guidance of the bearing.

[0035] The specific usage and function of this embodiment are as follows:

[0036] In this utility model, when in use, the bearing bottom ring and the cage are placed above the bearing mounting seat 4, the micro electric cylinder 401 is activated to extend the positioning block 402 to fix the bearing, and then the position of the cage is adjusted so that its filling part is aligned with the bottom of the feeding hopper 7.

[0037] Multiple sets of balls are pre-filled in the feeding hopper 7. The balls fall naturally by gravity and are blocked by the limit wedge 703 when they come into contact with it, stopping the fall. Then, the electric cylinder B705 is activated to push the wedge 706 forward. The wedge 706 moves into the through 704. During this process, the wedge 706 presses down the bottom ball, feeding the ball downward and discharging it. Then the ball falls into the bearing cage.

[0038] The program starts the servo motor 3 to drive the transmission worm 201 to rotate, and the transmission worm 201 drives the worm wheel 403 to rotate, thus rotating the bearing mounting seat 4 to feed it to one station and completing the feed.

[0039] After a complete set of bearings is loaded, start the electric cylinder A6 to raise the drive slider 601, lift the feeding hopper 7, and then retract the micro electric cylinder 401 to remove the bearings and reinstall them.
