Description

Technical Field

[0001] This invention relates to the field of workshop storage equipment technology, specifically to a workshop workpiece storage device and a grinding device. Background Technology

[0002] Multi-station lifting and rotating hoppers are a type of workshop workpiece storage device. They are specialized auxiliary equipment used in workshops for temporary storage and inter-process turnover of workpieces, suitable for workstation-side material management in workpiece processing and assembly scenarios. The core function of this device is the storage and retrieval of workshop materials. Through a multi-station rotating pallet structure, it achieves the orderly temporary storage of workpiece blanks and semi-finished products. Its rotating mechanism uses a geared motor to drive a sprocket and chain assembly, with sensors positioning the pallet positions. Material lifting and feeding are accomplished by a motor-reducer driven chain support plate. The entire operation is automated by an independent PLC controller. It mainly includes a turntable, adjusting and positioning plate, limit components, material support, and lifting actuators. In the workshop workflow, this hopper is directly deployed in the workstation area next to the processing equipment, allowing operators or robots to quickly complete workpiece loading, unloading, and storage operations. This significantly reduces the time spent on material handling between workstations, and is particularly suitable for workstation-side material turnover and temporary storage of workpieces such as brake horseshoes during grinding and other processing steps.

[0003] However, when using existing workshop workpiece storage devices, the brake shoes are placed on the bracket and between multiple limit rods.

Detailed Implementation

[0029] 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.

[0030] Please see Figures 1-11This invention provides a workshop workpiece storage device, including a turntable 1001 mounted on a workbench 1. Multiple workpiece storage units are disposed on the top of the turntable 1001. Each workpiece storage unit includes an adjusting plate 1002 rotatably connected to the top of the turntable 1001. Multiple arc-shaped grooves 1003 are formed on the top of the adjusting plate 1002. The rotation of the turntable 1001 and the adjusting plate 1002 can be driven by a rotation module. A limiting rod 1004 is inserted into the arc-shaped groove 1003, and the lower end of the limiting rod 1004 slides on the top of the turntable 1001. When the adjusting plate 1002 rotates, the limiting rod 1004 slides within the arc-shaped groove 1003, enabling adjustment of multiple workpiece storage units. The distance of the limiting rod 1004 is adjusted to regulate the diameter of the workstation. Multiple lifting rods 1008 are connected to the bottom of the turntable 1001 via a lifting module. Multiple circular holes 1007 are provided on the top of the turntable 1001. A bracket 1005 is provided above the adjusting plate 1002, and multiple sliding grooves 1006 are provided on the top of the bracket 1005. The limiting rod 1004 is inserted into the sliding groove 1006. When the lifting rod 1008 rises along the circular hole 1007, it drives the bracket 1005 to move upwards. When the lifting rod 1008 moves downwards to reset, it drives the bracket 1005 to move downwards to reset. Its structure and principle are well-known in this technical field and will not be described further here. To elaborate further, the main body of the device also includes a vibration mechanism mounted on the bracket 1005; the vibration mechanism includes a strip-shaped opening 212 on the bracket 1005, a ring 209 disposed within the strip-shaped opening 212, and a first moving mechanism for driving the ring 209 to move and rise and fall. The height of the strip-shaped opening 212 is sufficient to ensure that the ring 209 can move up and down within the strip-shaped opening 212; the vibration mechanism also includes a rotating ring 210 rotatably connected to the ring 209, a plurality of striking rods 211 connected to the ring 209, and a second moving mechanism for driving the striking rods 211 to move; the vibration mechanism also includes a drive mechanism for driving the ring 209 to rotate, and the striking rods 211... 11 is made of hard rubber to avoid scratching the surface of the limit rod 1004. When storage or retrieval is required, the bracket 1005 moves up and down along the limit rod 1004. At the same time, the first moving mechanism drives the ring 209 to move synchronously, and the second moving mechanism drives the striking rod 211 to move back and forth. The driving mechanism drives the rotating ring 210 to rotate, so that the striking rod 211 can reciprocate to strike and vibrate the side wall of the limit rod 1004 and transmit the vibration to the workpiece. This makes it easier to place the brake horseshoe flat and ensures that adjacent brake horseshoes fit together to avoid skewing and excessive gaps, thus ensuring the storage effect.

[0031] The first moving mechanism includes a first connecting block 204 connected to the bracket 1005, a lifting block 201, and a first elastic telescopic rod 202 connected between the first connecting block 204 and the lifting block 201; the first moving mechanism also includes a guide rail 207 connected to the lifting block 201 and a first slider 208 connected between the ring 209 and the guide rail 207; the first slider 208 slides on the guide rail 207; the first moving mechanism also includes a first distance sensor 206 connected to the first connecting block 204, which, when the limiting rod 1004 moves and adjusts within the sliding groove 1006, can drive the ring 209 and the rotating ring 210 to move synchronously, and simultaneously drive the first slider 208 to slide on the guide rail 207, when the bracket 1005 moves along the limiting rod 1004... During lifting and lowering, the first moving mechanism drives the ring 209 and the rotating ring 210 to lift and lower synchronously. The striking rod 211 slides on the surface of the limiting rod 1004. When there is a pit defect on the surface of the limiting rod 1004, the striking rod 211 can be inserted into the pit under the action of the second moving mechanism, preventing the ring 209 from moving and the rotating ring 210 from continuing to rotate. At this time, when the bracket 1005 continues to lift and lower, the first slider 208 and the first guide rail 207 drive the lifting block 201 to lift and lower. The first elastic telescopic rod 202 deforms, and the distance to the lifting block 201 is detected by the first distance sensor 206, thus facilitating the detection of pits on the surface of the limiting rod 1004 and ensuring the storage effect.

[0032] The second moving mechanism includes a first disk 302 connected to the striking rod 211, a moving rod 301 connected to the first disk 302, and a first spring 303 connecting the first disk 302 and the rotating ring 210. The moving rod 301 passes through the rotating ring 210. The second moving mechanism also includes a first pushing assembly for pushing the moving rod 301 to move. The first pushing assembly includes a second disk 401 connected to the moving rod 301, a pushing block 404 connected to the second disk 401, and a plurality of first triangular blocks 402 connected to the ring 209, allowing the pushing block 404 to slide on the side wall of the first triangular block 402. The second moving mechanism also includes a second distance sensor 403 connected to the second disk 401, which, when the rotating ring 210 rotates, drives the moving rod 301 to rotate synchronously. When the pushing block 404 moves close to the side wall of the first triangular block 402, the second moving mechanism can also move the moving rod 301. When the walls abut, the second disc 401 can be pushed to move away from the rotating ring 210. At the same time, the moving rod 301 and the first disc 302 drive the striking rod 211 to move, and the first spring 303 is compressed. When the pushing block 404 passes the first triangular block 402, the moving rod 301 and the second disc 401 can move and reset under the action of the first spring 303, and the first disc 302 drives the striking rod 211 to move and reset. By repeating this process, multiple striking rods 211 can reciprocate to strike and vibrate the side wall of the limiting rod 1004, and transmit the vibration to the workpiece. This makes it easier to place the workpiece flat, avoids skewing, ensures the storage effect, and is more convenient and faster. In addition, by detecting whether the distance between the second distance sensor 403 and the rotating ring 210 is the same, it can be determined whether the limiting rod 1004 is skewed, ensuring the storage effect.

[0033] The drive mechanism includes a gear ring 501 connected to the rotating ring 210, a gear 503 meshing with the gear ring 501, and a first rotating shaft 502 connecting the gear 503 and the ring 209; the drive mechanism also includes a driven bevel gear 504 connected to the first rotating shaft 502, a driving bevel gear 508 meshing with the driven bevel gear 504, and a second rotating shaft 506 connecting the driving bevel gear 508 and the ring 209; the drive mechanism also includes a rubber wheel 507 connected to the second rotating shaft 506 and a rubber wheel 507 connected to the second rotating shaft 506. The support block 505 between the ring 209 and the support block 505 allows the rubber wheel 507 to roll on the side wall of the limit rod 1004. When the bracket 1005 is raised or lowered, it can drive the rubber wheel 507 to roll on the surface of the limit rod 1004. When the rubber wheel 507 rolls, it can drive the active bevel gear 508 to rotate through the second rotating shaft 506, thereby driving the driven bevel gear 504 and the first rotating shaft 502 to rotate, and then drive the rotating ring 210 to rotate through the gear 503 and the gear ring 501, making the vibration and detection more comprehensive.

[0034] The main body of the device also includes a grinding device mounted on top of the workbench 1; the grinding device includes a loading / unloading module 11 and a grinding module 12; the loading / unloading module 11 and the grinding module 12 are known technologies in this field and will not be described in detail here. The grinding device also includes a first moving component for driving the grinding module 12 to move; the grinding device also includes a mounting block 13 connected to the workbench 1, a rotating disk 15 rotatably connected to the mounting block 13, and a motor 14 for driving the rotating disk 15 to rotate; the grinding device also includes two clamping blocks 16 sliding on the top of the rotating disk 15 and a second moving component for driving the clamping blocks 16 to move. When the brake shoes need to be ground, the loading and unloading module 11 places the brake shoes on the rotating disk 15, and the two clamping blocks 16 are placed in its inner hole. Then, the second moving component drives the two clamping blocks 16 to move away from each other to fix the brake shoes. Next, the first moving component drives the grinding module 12 to move and abut against the outer circle of the brake shoes. Then, the grinding module 12 is started, causing the grinding disk to rotate, and the motor 14 is started to drive the workpiece to rotate, realizing the grinding operation of the workpiece. This makes it easier and faster to fix and grind brake shoes of different sizes.

[0035] The first moving assembly includes a liquid reservoir 601 connected to the mounting block 13, a piston 606 sliding within the liquid reservoir 601, and a first lifting module 607 that drives the piston 606 to move up and down. A pressure sensor is installed on the side wall of the liquid reservoir 601, and the liquid reservoir 601 is connected to the mounting block 13 via a fixing plate 602. The liquid reservoir 601 is filled with hydraulic oil. The first moving assembly also includes a second connecting block 608 connected to the grinding module 12, a third connecting block 603 connected to the worktable 1, and a first lifting module 607 connecting the second connecting block 608 and the third connecting block 603. A telescopic sleeve 604; the first moving component also includes a first supply pipe 605 connecting the liquid storage cylinder 601 and the first telescopic sleeve 604. The piston 606 is driven to move downward along the liquid storage cylinder 601 by the first lifting module 607, so that hydraulic oil enters the first telescopic sleeve 604 through the first supply pipe 605, and can push the grinding module 12 to move, so that the grinding disc of the grinding module 12 abuts against the outer circle of the brake shoe. Furthermore, by detecting the pressure of the hydraulic oil by the pressure sensor, the pressing force between the grinding disc and the outer circle of the brake shoe can be kept constant.

[0036] The second moving assembly includes a chamber 801 disposed within the rotating disk 15, a rectangular tube 804 communicating with the chamber 801, and a second telescopic sleeve 805 connecting the clamping block 16 and the rectangular tube 804; the second telescopic sleeve 805 is communicating with the rectangular tube 804; the second moving assembly also includes an annular cover 802 rotatably connected to the rotating disk 15, a through hole 806 connecting the chamber 801 and the annular cover 802, and a second connecting pipe 803 connecting the first liquid supply pipe 605 and the annular cover 802. The hydraulic oil in the liquid storage cylinder 601 can enter the rotating disk 15 through the second connecting pipe 803, and then enter the second telescopic sleeve 805 through the rectangular tube 804. Under hydraulic action, it can push the two clamping blocks 16 to move away from each other and abut against and fix the inner hole of the brake horseshoe.

[0037] The grinding device also includes a limiting mechanism for limiting the clamping block 16; the limiting mechanism includes a limiting post 702 connected to the clamping block 16 and a sliding groove 701 that passes through the rotating disk 15; the limiting post 702 is inserted into the sliding groove 701; the grinding device also includes a limiting ring 705, a connecting plate 704 connected to the limiting ring 705, and a second lifting module 703 that drives the connecting plate 704 to move up and down; the grinding device also includes a plurality of annular limiting grooves 706 formed on the limiting ring 705, so that the limiting post 702 can be inserted. Within the annular limiting groove 706, when the two clamping blocks 16 move away from each other, the limiting post 702 can slide within the sliding groove 701. After the two clamping blocks 16 are fixed against the inner hole of the brake shoe, the connecting plate 704 is moved upward by the second lifting module 703. At the same time, the limiting ring 705 is moved upward, and the limiting post 702 is inserted into the annular limiting groove 706, thereby limiting the limiting post 702 and limiting the clamping block 16, making the fixing of the brake shoe more stable and reliable.

[0038] The grinding device also includes a detection mechanism for inspecting the workpiece after grinding. The detection mechanism includes a roller-type linear displacement sensor 904, a support frame 901 connected to the worktable 1, and a second spring telescopic rod 902 connecting the roller-type linear displacement sensor 904 and the support frame 901. The roller-type linear displacement sensor 904 includes a roller 905. The roller-type linear displacement sensor 904 is low in cost, and the roller 905 can be replaced. The detection mechanism also includes a second pushing component for pushing the roller-type linear displacement sensor 904 to move up and down. After the brake horse is fixed, the roller 905 of the roller-type linear displacement sensor 904 can abut against the outer circle of the brake horse. During grinding, the roller 905 can roll on the outer circle of the brake horse, which facilitates real-time detection of the outer circle's dimensions and ensures the quality of grinding.

[0039] The second pushing assembly includes a pushing frame 906 connected to the roller-type linear displacement sensor 904 and multiple second triangular blocks 907 connected to the side wall of the rotating disk 15; the pushing frame 906 can slide on the second triangular blocks 907, and when the rotating disk 15 and the brake horse are rotated, it can drive the second triangular blocks 907 to rotate. When the pushing frame 906 abuts against the side wall of the second triangular block 907, it can push the roller-type linear displacement sensor 904 and the roller 905 to move upward. The second spring telescopic rod 902... When the pusher 906 passes the second triangular block 907, the roller linear displacement sensor 904 and the roller 905 can move downwards and reset under the action of the second spring telescopic rod 902. By repeating this process, the roller 905 can move up and down on the outer circle, realizing detection at different heights, making the detection more comprehensive and the detection results more accurate. The thickness of the second triangular block 907 is sufficient. As the outer circle of the brake horseshoe is gradually polished, it ensures that the pusher 906 can always slide along the side wall of the second triangular block 907.

[0040] Working principle: During use, the brake horseshoes are stored in the workshop using the workshop workpiece storage device and grinding device, facilitating their storage and retrieval. During operation, the adjusting plate 1002 can be rotated via the rotating module, causing the limiting rod 1004 to slide within the arc groove 1003, thereby adjusting the distance of the limiting rod 1004 to accommodate workpieces of different sizes. The workpiece is then placed between the limiting rods 1004 and above the bracket 1005. When storage or retrieval is required, the lifting module can drive the lifting rod 1008 through the circular hole 1007 to lift and lower the bracket 1005. Furthermore, the rotation of the turntable 1001 facilitates the replacement of the workpiece storage unit.

[0041] When the bracket 1005 is raised or lowered, it can drive the first connecting block 204 to move. At the same time, the telescopic mechanism drives the lifting block 201 and the first guide rail 207 to move. Then, the first slider 208 drives the ring 209 and the rotating ring 210 to rise or fall along the side wall of the limiting rod 1004. Meanwhile, the striking rod 211 slides on the side wall of the limiting rod 1004, and the rubber wheel 507 can roll on the surface of the limiting rod 1004. When the rubber wheel 507 rolls, it can drive the driving bevel gear 508 to rotate through the second rotating shaft 506, thereby driving the driven bevel gear 504 and the first rotating shaft 502 to rotate. Then, the gear 503 and the gear ring 501 drive the rotating ring 210 to rotate. By detecting whether the distance between the second distance sensor 403 and the rotating ring 210 is the same, it can be determined whether the limiting rod 1004 is tilted, thus ensuring the storage effect.

[0042] When there is a pit defect on the surface of the limiting rod 1004, the striking rod 211 can be inserted into the pit under the action of the first spring 303, so that the ring 209 cannot move and the rotating ring 210 cannot continue to rotate. At this time, the lifting block 201 can be moved by the first slider 208 and the first guide rail 207, the first elastic telescopic rod 202 deforms, and the distance of the lifting block 201 is detected by the first distance sensor 206, so as to facilitate the detection of the pit on the surface of the limiting rod 1004 and ensure the storage effect.

[0043] When the rotating ring 210 rotates, it drives the moving rod 301 to rotate synchronously. When the pushing block 404 abuts against the side wall of the first triangular block 402, it pushes the second disk 401 to move away from the rotating ring 210. At the same time, the moving rod 301 and the first disk 302 drive the striking rod 211 to move, and the first spring 303 is compressed. When the pushing block 404 passes the first triangular block 402, the moving rod 301 and the second disk 401 can move and reset under the action of the first spring 303, and the first disk 302 drives the striking rod 211 to move and reset. By repeating this process, multiple striking rods 211 can reciprocate to strike and vibrate the side wall of the limiting rod 1004, and transmit the vibration to the workpiece, which makes it easier to place the workpiece flat, avoids skewing, and ensures the storage effect.

[0044] When the brake shoes need to be polished, the brake shoes are placed on the rotating disk 15 through the loading and unloading module 11, and the two clamping blocks 16 are placed in its inner hole. Then, the piston 606 is driven to move downward along the reservoir 601 through the first lifting module 607, so that the hydraulic oil can enter the rotating disk 15 through the first supply pipe 605 and the second connecting pipe 803. Then, it enters the second telescopic sleeve 805 through the rectangular tube 804. Under the action of hydraulic pressure, the two clamping blocks 16 can be pushed to move away from each other and abut against and fix the inner hole of the brake shoes.

[0045] Furthermore, hydraulic oil enters the first telescopic sleeve 604 through the first supply pipe 605 and can drive the grinding module 12 to move, so that the grinding disc of the grinding module 12 abuts against the outer circle of the brake shoe. In addition, by detecting the pressure of the hydraulic oil through the pressure sensor, the pressing force between the grinding disc and the outer circle of the brake shoe can be controlled to be constant, and the pressing force between the clamping block 16 and the inner hole of the brake shoe can also be kept constant.

[0046] When the two clamping blocks 16 move away from each other, they can drive the limiting post 702 to slide in the slide groove 701. After the two clamping blocks 16 are fixed against the inner hole of the brake shoe, the connecting plate 704 is moved upward by the second lifting module 703. At the same time, the limiting ring 705 is moved upward, and the limiting post 702 is inserted into the annular limiting groove 706, thereby limiting the limiting post 702 and limiting the clamping block 16. This makes the fixing of the brake shoe more stable and reliable. After the brake shoe is fixed, the roller 905 of the roller linear displacement sensor 904 can abut against the outer circle of the brake shoe.

[0047] Next, the grinding module 12 is started, causing the grinding disc to rotate, and the motor 14 is started to drive the workpiece to rotate, realizing the grinding operation of the workpiece. This makes it easier and faster to fix and grind brake horseshoes of different sizes.

[0048] During grinding, the roller 905 can roll on the outer circumference of the brake shoe, facilitating real-time detection of the outer circumference's dimensions and ensuring grinding quality. Furthermore, when the rotating disc 15 and the brake shoe rotate, they drive the second triangular block 907 to rotate. When the pusher 906 abuts against the side wall of the second triangular block 907, it pushes the roller-type linear displacement sensor 904 and the roller 905 upwards, stretching the second spring telescopic rod 902. When the pusher 906 passes the second triangular block 907, the roller-type linear displacement sensor 904 and the roller 905 can move downwards to reset under the action of the second spring telescopic rod 902. This repetitive motion allows the roller 905 to move up and down on the outer circumference, enabling detection at different heights, resulting in more comprehensive and accurate detection. The second triangular block 907 is sufficiently thick to ensure that the pusher 906 can always slide along the side wall of the second triangular block 907 as the outer circumference of the brake shoe is gradually ground.
