Description

Technical Field

[0001] The invention relates to the field of bearing production line conveying, and is a bearing conveying and discharging device and a working method thereof. Background Art

[0002] In bearing processing production lines, various adaptive conveying tracks are often involved to meet the state requirements of the bearings during actual processing or testing, especially when switching from one workstation to another. The workstation conversion setting at the corner is usually a difficult point, and has high requirements for reliability and stability. It must not damage the bearings and must meet the requirements of smooth workstation conversion. Existing bearing discharge devices, such as the authorization announcement number CN217126052U published in Chinese patent documents, the authorization announcement date is August 5, 2022, and the utility model name is "A feeding device for a bearing production line". It discloses a pushing mechanism, which mainly includes multiple groups of cylinders and push block structures, and uses the fixed stroke of the cylinder to realize the pushing operation of the corresponding stroke and direction of the push block, thereby realizing the requirements of workstation conversion and transportation. Although this structural method can realize discharge and transportation, the overall structural design and control are still complicated, and the coordination and cooperation of each cylinder are required to achieve reliable transportation. In addition, this device is mainly suitable for working conditions where the height difference range of the bearing conveying position is small. If the height difference range of the bearing conveying position is large, for example, the bearing rolls down from a high place to a low place, it is difficult to achieve reliable material receiving operation by relying solely on the V-shaped chute to receive the material. It is necessary to set up a corresponding blocking structure, and it is also necessary to consider whether the blocking time interval of the blocking structure is compatible with the pushing time interval of the pushing operation, otherwise it is difficult to achieve reliable pushing and discharging operation. The prior art also discloses a solution of using electromagnets in conjunction with relays to achieve interval blocking, but the timed blocking of the electromagnet and the intermittent pushing of the cylinder are still independently controlled and need to be adjusted every time they are used for a period of time. Otherwise, it is difficult to ensure long-term consistency, and if one has a problem and the other fails to stop in time, it is easy to cause bearing conveying disorder, and the subsequent adjustment and solution is more troublesome. For this reason, it is necessary to design a bearing conveying and discharging device that can meet the requirements of blocking and pushing linkage. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the present invention aims to provide a bearing conveying and discharging device and operating method thereof to the art. This device addresses the technical problem in existing similar bearing conveying and discharging devices that, during station conversion, the bearing blocking and pushing functions are not effectively linked, making it difficult to ensure consistent operation, thus affecting the stability and reliability of bearing conveying. This objective is achieved through the following technical solution.

[0004] Base comprises support, castor, and frame upper is provided with guide rail, and support and conveyer frames movable end contact site are provided with recoil spring, and castor is arranged on the pin of base bottom four, to carry mobile handler location. The lifting arm is fixed with the support frame, and the lifting arm is fixed with the support frame, and the lifting arm is fixed with the support frame, and the lifting arm is fixed with the support frame. In the above structure, the blocking mechanism in the blanking guide rail is linked with the push rod of the discharge guide rail, thereby effectively ensuring the consistency of the work of the two, and the bearing discharge conveying is more stable and reliable.

[0005] When the push rod pushes the bearing in the discharge rail, the lifting rod blocks the bearing at the discharge rail exit. When the push rod stops pushing the bearing and reverses direction, the lifting rod releases the blockage, allowing the bearing to fall from the discharge rail exit into the discharge rail. This structure, a specific embodiment of the first embodiment, allows the bearing to enter the discharge rail after being blocked by the discharge rail, effectively preventing the bearing from falling out of the discharge rail due to rolling inertia.

[0006] The bottom of the outlet of the blanking guide is lower than the top of the side of the discharge guide; when the push rod pushes the bearing in the discharge guide, the lifting rod forms a blockage on the bearing in the blanking guide; when the push rod stops pushing the bearing and moves in the opposite direction, the lifting rod releases the blockage on the bearing in the blanking guide, and the bearing enters the outlet of the blanking guide and is blocked by the top of the side plate of the discharge guide; when the push rod is separated from the vertical rod of the rocker assembly, the lifting rod resets under the action of its own weight, and squeezes the bearing at the outlet of the blanking guide over the side plate of the discharge guide into the discharge guide. This structure, as the specific structure of the second implementation scheme, realizes that after the bearing in the blanking guide is blocked, it is necessary to use the downward force of the lifting rod when it resets to push the bearing from the outlet of the blanking guide into the discharge guide. This design makes it easier to grasp the timing of the bearing entering the discharge guide from the blanking guide, and effectively prevents the bearing from forming interference friction with the push rod when entering the discharge guide.

[0007] The top of the lifting rod is provided with a detachable counterweight. Through this structure, the corresponding counterweight can be selected as needed to meet the force requirement of the lifting rod reset.

[0008] The bottom of the vertical rod of the swing arm assembly forms a magnetic connection with the top rod when in contact. This structure eliminates a rigid connection between the vertical rod and the top rod, resulting in a simpler structure and more flexible and reliable linkage. Furthermore, the magnetic attraction provides an effective reset force for the swing arm assembly when the top rod pulls the vertical rod, reliably resetting the lift rod.

[0009] A bolt seat is provided on one side of the push rod seat, which is fixedly connected to the push rod or base plate by a bolt. One end of the push rod is provided with a threaded connection that is threadedly connected to a stop nut and the push rod seat, and the stop nut is used to lock the push rod and the push rod seat. This structure facilitates the adjustment of the position of the push rod according to the actual linkage requirements of the material stop mechanism.

[0010] The push rod is adjustable and slidably fixed relative to the base plate. Specifically, a sliding hole is provided in the push rod or the base plate. A bolt slides through the sliding hole and secures the push rod to the base plate via a nut. This structure facilitates adjustment of the push rod's travel position to suit the material blocking operation of the blocking mechanism.

[0011] The connecting rod assembly is adjustable in length, comprising a main rod and a secondary rod. One end of the main rod is provided with a second sleeve that movably engages the second rotating shaft, and the other end is provided with a rotatable sleeve. The sleeve is secured to the main rod via radial screws. One end of the secondary rod is provided with a first sleeve that engages the first rotating shaft, and the other end is threadedly connected to the sleeve. This structure allows the length of the connecting rod assembly to be adjusted, thereby adjusting the sliding stroke of the baseboard relative to the track to meet actual linkage requirements.

[0012] The top surface of the rotating wheel is provided with a guide rail groove along its diameter. A guide block slides within the groove. The guide block is integrated with the second rotating shaft. The guide block is fixed to the guide rail groove via a locking nut connected to the second rotating shaft. This structure facilitates adjustment of the eccentric position of the connection between the rotating wheel and the connecting rod assembly, thereby adjusting the sliding stroke of the base relative to the track.

[0013] The working method of the bearing conveying and discharging device is as follows: the motor drives the rotating wheel to rotate, and the second rotating shaft eccentrically arranged on the rotating wheel drives the connecting rod assembly, and the connecting rod assembly drives the base plate and the slider to slide back and forth relative to the track; when the base plate drives the push rod to slide into the direction of extending into the discharging guide rail, a pushing operation is performed on the bearing in the discharging guide rail. At the same time, the base plate or the push rod drives the push rod seat, and the push rod seat drives the push rod to link the rocking rod assembly to swing, and the cross bar of the rocking rod assembly drives the protruding rod and the lifting rod to form an upward movement; when the push rod completes the pushing and moves in the opposite direction, the lifting rod releases the obstruction of the bearing in the blanking guide rail, and the bearing rolls along the outlet of the blanking guide rail into the discharging guide rail, and the bearing and the push rod are non-contact during the rolling process of the bearing.

[0014] The overall structure of the present invention is relatively reasonable, and the linkage between bearing blocking and discharging pushing is realized, thereby ensuring that when the bearing is transferred from one station guide rail to another, the transportation is relatively stable and reliable, and the problem of derailment and jamming is not likely to occur. It is suitable for use as a discharging device for station conversion transportation in various bearing conveying fields, or as a structural improvement of similar devices.

Implementation Method

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] like Figure 1 、 Figure 2 As shown, the bearing conveying and discharging device is located at the junction of the blanking guide rail 1 and the discharging guide rail 2, and a horizontal 90° angle is formed between the blanking guide rail and the discharging guide rail. The discharging device includes a mounting plate 4, a track 5, a slider 6, a base plate 7, a push rod 8, a connecting rod assembly, a rotating wheel 17, a motor 16, and a material blocking mechanism. The material blocking mechanism includes a bracket 14, a lifting rod 15, a rocker arm assembly, a mandrel 10, and a mandrel seat 9. The connecting rod assembly includes a main rod 19, a secondary rod 20, and a rod sleeve 21. One end of the main rod is sleeved with the rod sleeve. The rod sleeve is provided with a screw hole in the radial direction, and the main rod and the rod sleeve are fixed by connecting screws through the screw hole. One end of the secondary rod is provided with an external thread and is threadedly connected to the internal thread of the rod sleeve. The rocker arm assembly includes a swing seat 11, a cross bar 12, and a vertical bar 13. The cross bar and the vertical bar are connected to the swing seat at a 90° angle. The above-mentioned mounting plate, bracket, blanking guide rail and discharging guide rail are fixed to the same platform bracket, or are respectively fixed to independent platform brackets, and their positions are relatively fixed.

[0020] The upper end surface of the mounting plate 4 is fixedly connected to the track 5 by bolts, the slider 6 is slidably set on the track, the base plate 7 is fixed to the slider by bolts, and the push rod 8 is fixed to the base plate by bolts to form an adjustable sliding fixation, that is, the push rod is provided with a sliding hole that slides with the bolt, and the bolt passes through the sliding hole to connect to the base plate. When the bolt is loosened, the push rod is adjusted along the length direction, and when the bolt is tightened, the push rod is fixed to the base plate. A vertical first rotating shaft 18 is fixed at one end of the upper end surface of the base plate, and a motor 17 is fixed to the lower end surface of the mounting plate. The rotating shaft of the motor extends out of the upper end surface of the mounting plate and is connected to the rotating wheel 17. The top surface of the rotating wheel is provided with a guide rail groove 1701 along the diameter direction. A guide block is slidingly provided in the guide rail groove. The guide block is integrated with a second rotating shaft 22 parallel to the above-mentioned first rotating shaft. The guide block is connected to the guide rail groove by a locking nut connected to the second rotating shaft to form a fixation, and the fixed second rotating shaft is eccentric relative to the rotating wheel. The first rotating shaft is pivotally connected to the first sleeve 2001 at the other end of the secondary rod 20 of the connecting rod assembly. The second sleeve 1901 at the other end of the main rod 19 of the connecting rod assembly is pivotally connected to the second rotating shaft. The end of the second rotating shaft is connected to a washer and nut to form a stop. When the motor drives the rotating wheel to rotate, the connecting rod assembly links the base plate and the slider to reciprocate relative to the track. One end of the push rod extends into the discharge guide rail to reciprocate along the length of the discharge guide rail.

[0021] The lifting rod 15 of the above-mentioned material blocking mechanism slides vertically relative to the vertical through hole provided in the bracket 14. In the initial state, one end of the lifting rod extends into the blanking track 1 near the exit. One side of the lifting rod is provided with a protruding rod 1501 protruding relative to the bracket, and the side of the bracket is provided with a vertical sliding hole 1401 to guide the protruding rod to slide vertically. The swing seat 11 of the swing arm assembly swings relative to the bracket in a limited position through the swing axis. In the initial state, the cross bar 12 of the swing assembly is against the bottom of the protruding rod. A bolt seat is provided on one side of the push rod seat 9, and the bolt seat is fixedly connected to the push rod by a bolt member, or as shown in FIG. Figure 1 As shown, it is connected and fixed together with the bolt parts of the above-mentioned push rod and the base. One end of the push rod 10 is provided with a thread and is threadedly connected to the anti-rotation nut and the push rod seat. Through this threaded connection, the position of the push rod relative to the push rod seat is adjusted, and the push rod and the push rod seat are locked by the anti-rotation nut to prevent rotation. The end of the push rod is against one side of the vertical rod 13 of the rocker arm assembly. When the push rod slides back and forth with the push rod 8 or the slider 6, the end of the push rod is against or separated from one side of the vertical rod. When the push rod pushes the vertical rod into place, the swing seat swings relative to the bracket, and the cross bar drives the lifting rod to be lifted into place. When the lifting rod is lifted into place, the obstruction to the bearing 3 in the blanking guide rail 1 is released. When the push rod is separated from the vertical rod and into place, the lifting rod is reset to the initial state under the action of its own weight, and the convex rod of the lifting rod pushes the cross bar to the rocker arm assembly to form the initial state. The specific implementation linkage state is: when the push rod pushes the bearing in the discharge guide rail, the lifting rod blocks the bearing at the outlet of the blanking guide rail; when the push rod finishes pushing the bearing and moves in the opposite direction, the lifting rod releases the blockage of the bearing at the outlet of the blanking guide rail, and the bearing falls from the outlet of the blanking guide rail into the discharge guide rail.

[0022] Furthermore, the bottom of the outlet of the above-mentioned blanking guide rail 1 can also be designed to be lower than the top of the side of the discharge guide rail 2, so that the above-mentioned linkage state becomes: when the push rod 8 pushes the bearing 3 in the discharge guide rail, the lifting rod 15 blocks the bearing in the blanking guide rail; when the push rod finishes pushing the bearing and moves in the opposite direction, the lifting rod releases the obstruction of the bearing in the blanking guide rail, and the bearing enters the outlet of the blanking guide rail and is blocked by the top of the side plate of the discharge guide rail; when the push rod 10 is separated from the vertical rod 13 of the rocker assembly, the lifting rod resets under the action of its own weight, and squeezes the bearing at the outlet of the blanking guide rail over the side plate of the discharge guide rail into the discharge guide rail.

[0023] Furthermore, the top of the lifting rod 15 is threadedly connected or plugged into a counterweight 1502 , and a corresponding counterweight is selected as needed to meet the force requirement for resetting the lifting rod.

[0024] Furthermore, the bottom of the vertical rod 13 of the aforementioned rocker assembly forms a magnetic connection with the top rod 10 when in contact. Magnets are mounted on the end of the top rod and the bottom of the vertical rod, attracting them when they approach. The magnetic attraction is released when they move away or disconnect. This structure eliminates a hard connection between the top rod and the vertical rod, and the top rod pulling the vertical rod helps reset the rocker assembly.

[0025] The working method of the bearing conveying and discharging device is as follows: First, according to the discharging and conveying requirements of the bearing 3 in the discharging guide rail 2, for example, the push rod 8 is set to push the bearing in the discharging guide rail by a bearing spacing each time it reciprocates. The stroke position adjustment of the push rod includes adjusting the position of the push rod relative to the base plate 7, adjusting the eccentric position of the second rotating shaft 22 on the rotating wheel 17, and adjusting the length of the connecting rod assembly. The above adjustments are used together to adjust the stroke position of the push rod to meet the requirements of pushing the bearing in the discharging guide rail. At the same time, according to the blanking state of the bearing in the blanking guide rail 1, the working state of the blocking mechanism is adjusted, specifically by adjusting the position of the push rod 10 relative to the push rod seat 9, thereby adjusting the position of the push rod to push the rocker assembly to link the lifting rod 15 to lift, that is, to release the blocking state of the bearing in the blanking guide rail, so that the bearing of the blanking guide rail avoids interference with the push rod when it falls into the discharging guide rail. The specific working state is: the motor 16 drives the rotating wheel to rotate, and the second rotating shaft 22 eccentrically arranged on the rotating wheel drives the connecting rod assembly, and the connecting rod assembly drives the base plate and the slider 6 to slide back and forth relative to the track 5; when the base plate drives the push rod to slide into the direction of extending into the discharge guide rail, a pushing operation is performed on the bearing in the discharge guide rail. At the same time, the push rod drives the ejector seat, and the ejector seat drives the ejector-linked rocker assembly to swing, and the cross bar of the rocker assembly drives the protruding rod 1501 and the lifting rod to form an upward movement; when the push rod completes the pushing and moves in the opposite direction, the lifting rod releases the obstruction to the bearing in the blanking guide rail, and the bearing rolls down along the outlet of the blanking guide rail into the discharge guide rail, and during the time period of the bearing rolling down, the push rod moves in the opposite direction until there is no interference with the bearing, that is, a bearing station conversion and transportation is completed.

[0026] The above content is intended to illustrate the technical means of the present invention and is not intended to limit the technical scope of the present invention. Those skilled in the art may make obvious improvements or substitutions to the present invention in combination with existing common knowledge, which also fall within the scope of protection of the claims of the present invention.
