Description

Technical Field

[0001] This invention relates to the field of bearing assembly technology, specifically to an automatic assembly and feeding device and method for double-row tapered roller bearings. Background Technology

[0002] Double-row tapered roller bearings consist of an outer ring with double-row raceways and two independent inner ring assemblies. In the manufacturing process of this type of bearing, after the independent machining of the inner and outer rings and the assembly of the inner ring assemblies, the two inner ring assemblies need to be installed into the outer ring from both sides to form a complete bearing assembly for subsequent processes such as clearance testing. In practice, the two inner ring assemblies need to be manually placed into the outer ring, and then the assembled assembly is carefully laid horizontally into the clearance storage channel. During this process, the inner ring assemblies are prone to colliding with the raceways of the outer ring, causing damage to the raceways and making them easy to slip out. This requires one operator to manually load each assembly, which not only affects product quality but also increases manufacturing costs and labor intensity. Summary of the Invention

The automatic inner component flipping mechanism is mounted on the base frame and is used to flip the inner ring assembly from a flat position to an upright position and alternately feed it to both sides of the assembly station. The automatic outer ring flipping mechanism is mounted on the base frame and is used to flip the outer ring from a flat position to an upright position with its axis horizontal and transport it to the center of the assembly station. The automatic assembly mechanism is used to simultaneously push the two inner ring assemblies into the outer ring located in the assembly station from both sides. The material blocking and releasing mechanism is set at the outlet end of the assembly station and is used to block and position the outer ring before assembly and release the assembled components after assembly. The motion track system includes two inner component conveying tracks connecting the inner component flipping mechanism and the assembly station, and an outer ring conveying track set between the two inner component conveying tracks.

[0005] In a preferred embodiment, the automatic flipping mechanism for the inner component includes two flipping cylinders arranged opposite each other, and a rotating base plate connected to the output end of each of the two flipping cylinders. The rotating base plate is used to support the inner ring component and can rotate outward in a direction away from each other, so that the inner ring component flips from a flat position to an upright position.

[0006] In a preferred embodiment, the automatic flipping mechanism of the inner component further includes a power plate connected to the side end of the rotating base plate. The power plate has a preset tilt angle for receiving the flipped inner ring component and providing it with rolling power.

[0008] In a preferred embodiment, the outer ring automatic flipping mechanism includes a straight material channel, an arc-shaped flipping material channel, and a guide material channel connected in sequence, wherein the guide material channel forms the inner side of the straight track.

[0009] In a preferred embodiment, the bottom of the outer ring conveying track is provided with an outer ring road rail, and the outer ring road rail is provided with a buffer layer on the surface of the impact area where the outer ring slides down from the arc-shaped turning channel.

[0010] In a preferred embodiment, at least one of the two straight tracks is mounted on the inclined base plate via an adjustable base that can move axially along the outer ring to adjust the distance between the inner sides of the two straight tracks.

[0011] In a preferred embodiment, the automatic assembly mechanism includes two pusher drive components respectively disposed on both sides of the assembly station, and the output end of the pusher drive component is connected to a push plate.

[0012] In a preferred embodiment, the two outlet ends of the assembly station are provided with inner component baffles, and the inner component baffles are provided with inner component baffle strips for fitting with the inner conical surface of the inner ring component to straighten the posture of the inner ring component.

[0013] A second aspect of the present invention provides an automatic assembly and feeding method for double-row tapered roller bearings, employing the aforementioned automatic assembly and feeding device for double-row tapered roller bearings, comprising the following steps: Step 1: Flip the first inner ring component from a flat position to an upright position, and roll it along the motion track system to the first side of the assembly station; Step 2: Flip the outer ring from a flat position to an upright position, and let it roll along the motion track system to the center position of the assembly station, where it is blocked and positioned by the material feeding mechanism. Step 3: Flip the second inner ring assembly from a flat position to an upright position, and roll it along the motion track system to the second side of the assembly station; Step 4: Once the first inner ring assembly, outer ring, and second inner ring assembly are all in place, drive the pusher components on both sides to simultaneously push the first inner ring assembly and the second inner ring assembly into the outer ring to complete the assembly. Step 5: The material feeding mechanism releases its obstruction of the outer ring, allowing the assembled components to slide automatically out into the storage channel of the clearance detection equipment under the action of gravity.

Through the structural design of the motion track system, both the inner and outer ring components are equipped with independent running tracks, and can move smoothly by gravity rolling during assembly, which significantly reduces the risk of collision damage to the outer ring raceway and the inner ring component rollers.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0019] See Figures 1-3 This embodiment discloses an automatic assembly and feeding device for double-row tapered roller bearings, which is used to realize the automated assembly and feeding of the bearing outer ring 3 and two inner ring components 1.

[0020] The device includes a base frame 30, an internal component automatic flipping mechanism 2, an outer ring automatic flipping mechanism 4, an automatic assembly mechanism 5, and a material blocking and unloading mechanism 6. All mechanisms work together under the coordinated control of the PLC control system to complete the entire assembly process.

[0021] Specifically, the inner component automatic flipping mechanism 2 receives the inner ring component 1 from the upstream feeding line and flips it from a flat position to a vertical position ready for assembly, alternately feeding it to the left and right sides of the assembly station. The outer ring automatic flipping mechanism 4 receives the outer ring 3 from the upstream feeding line in a flat position and flips it 90 degrees, changing it from a flat position to a vertical rolling position with the axis horizontal, and then conveys it to the center of the assembly station. The automatic assembly mechanism 5 synchronously and coaxially pushes the two inner ring components 1 conveyed from both sides into the outer ring 3 to complete the assembly. The material blocking and releasing mechanism 6 is located at the downstream outlet of the assembly station, used to block and position each component during the assembly process, and release it after assembly to allow it to enter the next process.

[0022] like Figure 3 and Figure 4 As shown, the automatic tilting mechanism 2 of the inner component is fixedly connected to one end of the device base frame 30 via a mounting plate. It includes two opposing 90° tilting cylinders 24 fixedly connected to the top surface of the mounting plate. The tilting cylinders 24 are vertically arranged, and the center distance between the axes of the two tilting cylinders 24 is preferably 70-80 mm. Each tilting cylinder 24 has a fixedly mounted rotating base plate for supporting the inner ring component 1 at its output end; these are a left base plate 7 and a right base plate 8. During operation, the rotating base plates of the two tilting cylinders 24 can rotate 90° to the outermost direction, respectively. Furthermore, the projections of the left base plate 7 and the right base plate 8 on the horizontal plane intersect each other, thereby ensuring that the movement trajectories of the left base plate 7 and the right base plate 8 do not interfere with each other when they tilt with their respective cylinders.

[0023] Furthermore, the automatic flipping mechanism 2 for the inner components also includes a power plate 9 fixedly connected to the sides of the left base plate 7 and the right base plate 8, respectively. This power plate 9 is used to generate rolling power for the inner ring assembly 1 after flipping. Preferably, the power plate 9 is made of nylon, which reduces hard collisions and impacts on the rollers of the inner ring assembly 1 during the flipping process, thus protecting the precision surfaces of the bearing. As shown in the figure, the rolling plane of the power plate 9 forms a preset tilt angle with the horizontal plane, preferably 15-18°. When the left base plate 7 or the right base plate 8 is flipped to the outer 90° position by the 90° flipping cylinder 24, the inner ring assembly 1 will be converted to a vertical state, and its bottom will contact the rolling plane of the power plate 9. At this time, the tilt angle of the power plate allows the inner ring assembly 1 to roll smoothly along the surface of the power plate 9 to the next station.

[0024] Correspondingly, in this embodiment, the device also includes a motion track system for guiding the alternatingly falling inner ring components 1 from the left and right sides to precise assembly preparation positions. See again Figure 1Specifically, the motion track system includes an inner component conveying track connecting the inner component automatic flipping mechanism 2 and the assembly station, and an outer ring conveying track 29 for guiding the outer ring from the outer ring automatic flipping mechanism to the assembly station. More specifically, the inner component conveying track includes two inclined track segments 25 near the inner component automatic flipping mechanism 2 and two straight track segments 26 near the automatic assembly mechanism 5. The two inclined track segments 25 are respectively connected to the flipping feeding areas of the left bottom plate 7 and the right bottom plate 8 to directly receive the inner ring component 1 rolling off the power plate 9. These two sets of inclined track segments 25 are designed in an inverted V-shape, that is, the entrance ends of the two sets of tracks are far apart from each other, while the exit ends gradually converge inward and move closer to each other, respectively connecting to the entrance ends of the two parallel straight track segments 26 located in the middle of the lower part of the device.

[0025] Furthermore, both sets of inclined rails 25 are fixedly installed on a first inclined base plate 27, which is fixedly connected to the base frame 30 by a vertical plate, giving it a preset inclination angle to ensure that the inclined rails 25 installed on it can obtain the required slope. Below the first inclined base plate 27, a second inclined base plate 28 is provided, with an adjusting base plate 20 connected to each side of the top surface of the second inclined base plate 28. The inclination angle of the adjusting base plate 20 matches that of the first inclined base plate 27 and is connected to it. The aforementioned two straight rails 26 are fixedly connected to the adjusting base plates 20, with the inlet end of the straight rail 26 smoothly connected to the outlet end of the corresponding inclined rail 25, and the two straight rails 26 are arranged parallel to each other, with their spacing matching the height of the outer ring 3.

[0026] See Figure 2 and Figure 5The outer ring automatic flipping mechanism corresponds to the entrance end of the straight track 26. This mechanism consists of a straight material channel 23, an arc-shaped flipping material channel 10, and a guide material channel 11 connected in sequence. It should be noted that the guide material channel 11 forms the inner track side of one of the straight tracks 26. In other words, each straight track 26 has an inner side and an outer side, where the inner side is the guide material channel 11, and the channel formed between the two parallel inner sides constitutes the outer ring conveying track 29 for conveying the outer ring 3. Specifically, the outer ring 3 enters the straight material channel 23 from the upstream equipment in a flat position and slides down along the arc-shaped flipping material channel 10. To achieve the transition from a flat to an upright position, the arc-shaped tilting channel 10 is constructed as a smoothly transitioning arc-shaped track with a radius of curvature of R120mm. It is preferably made of 2mm thick stainless steel plate, precisely cut and formed using laser cutting technology. To ensure the structural strength and dimensional stability of the arc-shaped track and prevent deformation under the impact of the outer ring 3, two equally thick, arc-shaped reinforcing plates with a radius of curvature of R120mm are welded to both sides of the arc-shaped tilting channel 10. As the outer ring 3 slides down the arc-shaped tilting channel 10, its axial direction gradually flips from vertical to horizontal, eventually falling upright into the space between the two guide channels 11 at the bottom of the arc-shaped tilting channel 10, i.e., within the outer ring conveying track 29.

[0027] See Figure 3 and Figure 6 The guide channel 11 is fixedly connected to the aforementioned adjusting base plate 20 via the outer ring rail 12. The outer ring rail 12 is preferably made of wear-resistant hard steel strips, and consists of two rails arranged along the rolling direction of the outer ring 3. The two outer ring rails 12 cooperate to provide a rolling support surface for the vertically positioned outer ring 3. Specifically, in the impact area where the outer ring 3 slides down from the arc-shaped turning channel 10 and first contacts the outer ring rail 12, a buffer layer 13 is laid on the surface of the outer ring rail 12. This buffer layer 13 is preferably made of polyurethane or rubber material with a certain thickness and elasticity, which can effectively absorb the impact energy when the outer ring 3 falls, providing excellent buffering and energy absorption, and preventing the outer ring 3 from being damaged by rigid collisions.

[0028] To achieve compatibility with different models of outer ring 3, in this embodiment, one of the adjusting base plates 20 is an adjustable structure, such as... Figure 3 As shown, it has the ability to be adjusted by translation along the axial direction (i.e., left and right) of the outer ring 3. For example, the adjustment base plate 20 is provided with several elongated holes for installing locking components. When changing to a different height model of the outer ring 3, the operator only needs to unlock and move the adjustment base plate 20 to the appropriate position and then relock it. The adjustment process is convenient and quick.

[0029] The automatic assembly mechanism 5 corresponds to the end position of the motion track system. It guides the outer ring 3 to the central assembly position via the motion track system, and guides the two inner ring components 1 from the left and right sides to the sides of the assembly position. This automatic assembly mechanism includes two inner component pushing cylinders 14, respectively fixedly mounted on the left and right adjusting base plates 20. The extension and retraction direction of their piston rods is consistent with the axial direction of the outer ring 3. A push plate 16 is fixedly connected to the end of the piston rod of each inner component pushing cylinder 14. When the inner component pushing cylinder 14 is in its fully retracted initial state, the front end of the push plate 16 will completely retract beyond the straight track 26, thereby avoiding the falling and rolling channel of the inner ring component 1 and ensuring that the inner ring component 1 can smoothly and unobstructedly enter the assembly position. When the assembly command is issued, the piston rod of the inner component pusher cylinder 14 extends, and the pusher plate 16 pushes the inner ring component 1 towards the center. At the fully extended end position, the front end face of the pusher plate 16 is flush with the plate surface of the guide channel 11. This design ensures that the inner ring component 1 is completely and accurately pushed into the interior of the outer ring 3, achieving precise assembly. After the assembly and material release are completed, the pusher cylinder 14 retracts. During this period, it acts as a temporary material channel to ensure that the outer ring 3 can roll normally without jamming.

[0030] See Figure 2 and Figure 7 An inner component baffle 18 is fixedly installed at the outlet position of the assembly position. This inner component baffle 18 is fixedly mounted on the adjusting base plate 20 and provides a precise pre-stopping position for the inner ring component 1 rolling down from the inner component automatic flipping mechanism 2, ensuring that the axial direction of the inner ring component 1 is basically consistent with the thrust direction of the pusher cylinder 14. To further improve the stopping posture accuracy of the inner ring component 1, an inner component baffle strip 21 with a single-sided inclined surface is fixed on the side of the inner component baffle 18 facing the assembly position. The dimensions of this inner component baffle strip 21 are preferably 3mm in height and 5mm in width. When the inner ring component 1 rolls into position and contacts the inner component baffle 18, its inner ring conical surface will fit against the inclined surface of the inner component baffle strip 21. This fit provides a slight straightening and guiding effect on the inner ring component 1, keeping it in a more vertical and stable assembly posture, thereby significantly reducing the risk of jamming during the subsequent advancement of the inner component pusher cylinder 14 and ensuring the smoothness of the assembly process.

[0031] See Figure 2The material feeding and blocking mechanism 6 is located at the outlet end of the assembly station. It includes a linear sliding cylinder assembly 17, an outer ring baffle plate 15 connected to its output end, and photoelectric switches 19. Before the assembly action is executed, the linear sliding cylinder assembly 17 drives the outer ring baffle plate 15 to the rising blocking position. The blocking surface of the outer ring baffle plate 15 is exactly in front of the rolling path of the outer ring 3, accurately blocking and positioning the outer ring 3 to be assembled at the assembly station, preventing it from sliding out under gravity. When all three photoelectric switches 19 used to detect the positioning of the inner ring assembly 1 and the outer ring 3 are triggered and lit, it indicates that the outer ring 3 and the two inner ring assemblies 1 are in position, and the control system then issues an assembly command. After the assembly is completed, the magnetic switch on the inner component pushing cylinder 14 detects that the piston has reached the end position and feeds back a signal to the control system. The control system then issues a feeding command to the linear sliding cylinder assembly 17. After receiving the command, the linear sliding cylinder assembly 17 drives the outer ring baffle plate 15 to move downward, releasing the obstruction of the outer ring 3. At this point, the assembled components, under their own weight and the inherent inclination of the entire working plane of the device, will roll out of the assembly station and enter the downstream clearance detection equipment storage channel along the discharge channel.

[0032] Based on the automatic assembly and feeding device for double-row tapered roller bearings provided in the foregoing embodiments, this embodiment also provides an automatic assembly and feeding method for double-row tapered roller bearings, including the following steps: Step 1: Inner ring component 1 is fed from the upstream equipment. It enters the automatic inner component flipping mechanism 2 along the conveyor line and stops on the left cross base plate. At this time, the corresponding flipping cylinder 24 drives the left base plate 7 to flip 90° outward and slide onto the power plate 9. It then rolls along the motion track system into the left position to be assembled, where it is blocked by the left inner component baffle plate 18. Simultaneously, a position detection photoelectric switch 19 is triggered. The control system records the signal and waits for the next instruction.

[0033] Step Two: Outer Ring 3 Feeding and Rotation. Synchronized with Step One, one outer ring 3 enters the straight feed channel 23 from upstream in a flat position and rolls to the arc-shaped rotating feed channel 10. After rotating, it falls vertically between the two guide feed channels 11 and rolls forward along the outer ring track 12 until it reaches the central fitting position. The end face of the outer ring 3 is blocked by the outer ring baffle plate 15 in the raised state of the material feeding mechanism 6, which simultaneously triggers the second positioning detection photoelectric switch 19. The control system records the signal and waits.

[0034] Step 3: Inner ring component 1 (No. 2) is fed. After step 1 is completed, the left base plate 7 returns to its initial horizontal position. Inner ring component 1 (No. 2) enters the automatic inner component flipping mechanism 2 and stops on the right cross base plate. At this time, the flipping cylinder 24 on the right side drives the right base plate 8 to flip outward by 90°. Inner ring component 1 (No. 2) follows the same motion mechanism as in step 1, rolls into the position to be assembled on the right, is blocked by the inner component baffle 18 on the right, and simultaneously triggers the third positioning detection photoelectric switch 19.

[0035] Step 4: Perform assembly and unloading. When all three photoelectric switches 19 are triggered, signals are transmitted to the control system, which issues an assembly command. Simultaneously, the piston rods of the inner component pushing cylinders 14 on both sides extend synchronously, pushing the left and right inner ring components 1 smoothly and coaxially into the outer ring 3 located in the center via the push plate 16. When both inner component pushing cylinders 14 reach the end of their stroke, the magnetic switches on their pistons are triggered, and signals are fed back to the control system. The control system then issues a command to the linear sliding cylinder assembly 17 of the material release mechanism 6, causing it to drive the outer ring baffle plate 15 downward, releasing the obstruction to the outer ring 3. Under the combined action of gravity and the inclined slope, the assembled bearing assembly automatically rolls out from the assembly station and enters the storage channel of the clearance detection equipment.

[0036] Step 5: Mechanism Reset and Cycle. After the assembly slides out, the signal of the photoelectric switch 19 that was originally blocked disappears. The control system then issues a reset command, and the internal component push cylinder 14 and the material blocking and unloading mechanism 6 return to their initial state, ready to receive the next set of parts. At this point, a complete automatic assembly cycle ends.

[0037] The feeding device and method provided in this embodiment completely replace the traditional manual handling and assembly operation mode. Through the ingenious design and coordinated operation of the inner component automatic flipping mechanism, outer ring automatic flipping mechanism, automatic assembly mechanism, and material blocking and unloading mechanism, supplemented by a motion track system, the automated, assembly-line assembly and feeding of the outer ring of the double-row tapered roller bearing with the two inner ring components can be realized. This significantly improves the production efficiency of the assembly process, reduces the labor intensity of operators and the labor costs of enterprises, and has good application prospects.
