Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, and in particular to a clamping and flipping device with a braking system. Background Technology

[0002] In the production and processing of large workpieces, different surfaces of the workpiece need to be processed. However, some parts on the workpiece need to be manually assembled before all surfaces are processed. Therefore, during the workpiece processing, the workpiece needs to be flipped at different angles to facilitate the assembly of some parts.

[0003] Currently, the common methods for workpiece flipping are to manually pry the workpiece up with a crowbar or to use a conventional flipping machine to flip the workpiece to 90° or 180°. Manually using a crowbar is time-consuming and labor-intensive, and there are dangers in the flipping process. Conventional flipping machines have a single flipping angle, and various counterweights are required to facilitate flipping, making them unsuitable for changing between different products.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Example 1: Reference Figures 1 to 10This application provides a clamping and tilting device with a braking system, including a base 1 and a clamping and tilting device disposed on the base 1. The clamping and tilting device includes: The clamping system 2 includes a first telescopic arm 21 and a second telescopic arm 22 symmetrically arranged, the first telescopic arm 21 and the second telescopic arm 22 being used to move along a first direction under the synchronous drive of the first drive mechanism 23. Figure 1 (As shown in the X direction) move synchronously; The lifting system 3, located on one side of the base 1, includes a second drive mechanism 31 connected to the clamping system 2, for driving the clamping system 2 along a second direction ( Figure 1 (As shown in the Y direction) it moves back and forth, where the first direction is perpendicular to the second direction; The flipping system 5 includes a first clamping component 51 disposed on a first telescopic arm 21 and a second clamping component 52 disposed on a second telescopic arm 22. The first telescopic arm 21 and the second telescopic arm 22 respectively drive the first clamping component 51 and the second clamping component 52 to move along a first direction to clamp the workpiece. The first clamping component 51 is equipped with a flip motor 53, which can drive the first clamping component 51 to rotate. When the first clamping component 51 and the second clamping component 52 clamp the workpiece, the flip motor 53 can synchronously drive the second clamping component 52 and the workpiece clamped by the first clamping component 51 and the second clamping component 52 to rotate. Braking system 4 is installed on the second telescopic arm 22. It includes a brake component 44, which is connected to the second clamping component 52. When the flipping system 5 flips the workpiece to a preset angle, the braking system 4 brakes the second clamping component 52 through the brake component 44 so that the workpiece is flipped at the preset angle.

[0027] In this embodiment, the base 1 is welded from steel and has an overall rectangular structure to ensure the stability of the equipment during operation. Multiple adjustable anchor bolts are provided at its bottom for easy leveling of the equipment during installation, effectively adapting to installation sites with varying flatness. Simultaneously, the base 1 has multiple pre-drilled mounting holes for securing the clamping and tilting device and other related auxiliary components, ensuring a secure and reliable connection between all parts.

[0028] The first telescopic arm 21 and the second telescopic arm 22 have similar structures, both consisting of an integrally molded arm body. The arm body is made of alloy material, which reduces the overall weight while ensuring strength, thus facilitating the flexible operation of the equipment.

[0029] The first drive mechanism 23 is mounted on the first telescopic arm 21. The first telescopic arm 21 is connected to the second telescopic arm 22 through a synchronizer 24. When the first drive mechanism 23 drives the first telescopic arm 21 to move along the first direction, the first telescopic arm 21 synchronously drives the second telescopic arm 22 to move along the first direction through the synchronizer 24.

[0030] The second drive mechanism 31 is a screw jack, comprising a second motor 311, a reducer, a screw, and a nut. The power output from the second motor 311 is reduced and amplified by the reducer before being transmitted to the screw. The nut is fitted onto the screw and is connected to the clamping system 2. When the screw rotates, the nut converts the rotational motion of the screw into linear motion reciprocating in the second direction, thereby driving the clamping system 2 connected to the nut to reciprocate in the second direction.

[0031] In one feasible embodiment, linear guide rails are provided on both sides of the lifting system 3. The clamping system 2 cooperates with the linear guide rails through a slider to ensure that there is no swaying or deviation during the lifting process, and that it always moves smoothly along the second direction. At the same time, mechanical limit switches and buffer devices are respectively provided at the upper and lower stroke ends of the lifting system 3. When the clamping system 2 rises or falls to the limit position, the mechanical limit switch will be triggered in time, and a signal will be transmitted to the control system to stop the motor and prevent excessive lifting and lowering from damaging the equipment. The buffer device can buffer and decelerate when approaching the limit position, reducing the impact of the impact force on the various components of the equipment.

[0032] The first clamping component 51 and the second clamping component 52 have the same structure, both consisting of a clamping plate, a clamping arm, and a connecting seat. The clamping plate is made of alloy steel, and its inner side is provided with anti-slip texture, which can effectively increase the friction between the clamping component and the workpiece and prevent the workpiece from sliding during the flipping process. One end of the clamping arm is connected to the clamping plate, and the other end is fixed to the telescopic arm through the connecting seat. The connecting seat is provided with multiple adjusting bolts to facilitate fine adjustment of the position and clamping angle of the clamping components to adapt to the clamping requirements of workpieces of different shapes and sizes.

[0033] The output shaft of the flipping motor 53 is connected to the rotating shaft of the first clamping component 51 via a coupling. A bearing is installed at the connection point between the rotating shaft and the first clamping component 51. The rotating shaft of the first clamping component 51 transmits the power of the motor to the first clamping component 51, allowing the flipping motor 53 to rotate the first clamping component 51 around its own axis. Similarly, the second clamping component 52 is equipped with a rotating shaft, allowing it to rotate around its own axis. After the first and second clamping components 51 and 52 clamp the workpiece, when it is necessary to flip the workpiece, the flipping motor 53 drives the rotating shaft of the first clamping component 51 to rotate. As the first clamping component 51 rotates around its own axis, it drives the workpiece and the second clamping component 52 to rotate synchronously, achieving the workpiece flipping operation. A rotary encoder is installed on the flipping motor 53 to monitor the workpiece's flipping angle in real time and feed the angle information back to the control system for accurate control of flipping to the preset angle.

[0034] By adopting the above technical solution, the workpiece can be flipped at any angle and maintained in the flipped state. With the flipping system 5 set up, there is no need to make counterweights or limiting tools, and it can be flipped at any angle.

[0035] Example 2: Continue to refer to Figure 2 In one feasible embodiment, the braking system 4 further includes a drive assembly consisting of a first cylinder 41 and a connecting rod 42, and an adjustment mechanism 43, wherein: The drive shaft of the first cylinder 41 is connected to the connecting rod 42, the connecting rod 42 is connected to the adjusting mechanism 43, the adjusting mechanism 43 abuts against the brake component 44, the first cylinder 41 drives the adjusting mechanism 43 through the connecting rod 42 and pushes the brake component 44 to start, so that the brake component 44 brakes the second clamping component 52.

[0036] The brake component 44 includes two brake calipers 441 and a brake disc 443, wherein the brake disc 443 is fixedly connected to the second clamping component 52; the two brake calipers 441 are respectively disposed on both sides of the brake disc 443, and each brake caliper 441 is provided with a brake pad 442 on the side of the brake caliper 441 closest to the brake disc 443, with the brake pad 442 and the brake disc 443 spaced apart by a preset distance; the top of each of the two brake calipers 441 abuts against the adjusting mechanism 43. When the adjusting mechanism 43 pushes the two brake calipers 441, the two brake calipers 441 move toward the brake disc 443, and the brake pads 442 of the two brake calipers abut against the brake disc 443 and brake the brake disc 443, thereby braking the second clamping component 52.

[0037] In this embodiment, the adjustment mechanism 43 mainly consists of an adjustment seat and a thrust plate 431. The adjustment seat is bolted to the second telescopic arm 22, providing stable support for the entire adjustment mechanism 43. The thrust plate 431 is connected to the brake component 44 and transmits thrust.

[0038] The two ends of the connecting rod 42 are connected to the drive shaft of the first cylinder 41 and the thrust plate 431 of the adjustment mechanism 43 respectively through spherical bearings. The spherical bearings can adapt to a certain angle deviation, ensuring that even if there is an installation error or a slight deformation of the parts during the cylinder driving process, the thrust can be smoothly transmitted to the adjustment mechanism 43 without any jamming.

[0039] In one feasible embodiment, an air lock 47 is also provided between the first cylinder 41 and the thrust plate 431. The connecting rod 42 passes through the air lock 47 and is connected to the thrust plate 431. After the first cylinder 41 pushes the connecting rod 42 and drives the brake component 44 to brake the second clamping component 52, the air lock 47 locks the connecting rod 42 to prevent the connecting rod 42 from moving. At the same time, it prevents the first cylinder 41 from suddenly losing air supply, causing the first cylinder 41 to lose the pushing force on the connecting rod 42, causing the connecting rod 42 to spring back, thereby causing the brake component 44 to fail.

[0040] Continue to refer to Figure 2 In one feasible embodiment, the thrust plate 431 has a through groove 4311, the upper and lower openings of the through groove 4311 are smaller at the top and larger at the bottom, so that the side wall of the through groove 4311 is inclined inward at a certain angle from top to bottom in the vertical direction. The inclination angle of the inner side wall of the through groove 4311 is usually in the range of 15°-30°. The braking system 4 also includes an elastic structure 45, which is fixedly installed at the bottom of the air lock 47 and partially disposed in the through groove 4311. The top ends of the two brake calipers 441 are disposed in the through groove 4311 and are respectively connected to the elastic structure 45, wherein the top ends of the two brake calipers 441 abut against the inner side wall of the through groove 4311.

[0041] The braking system 4 also includes a mounting plate 46, which is connected to the bottom of the air lock 47. The bottom ends of the two brake calipers 441 are rotatably mounted on the mounting plate 46. When the flipping system 5 flips the workpiece to a preset angle, the flipping motor 53 stops driving the first clamping component 51 to rotate. At the same time, the first cylinder 41 drives the connecting rod 42 to extend. The connecting rod 42 pushes the thrust plate 431 of the adjusting mechanism 43 to move downward. The top of the brake caliper 441 is in the through groove 4311. As the thrust plate 431 moves downward... The two sides of the through groove 4311 push the two brake calipers 441 to compress the elastic structure 45 inward, so that the two brake calipers 441 move inward toward the brake disc 443. The brake calipers 441 drive the brake pads 442 to gradually come into contact with the surface of the brake disc 443. When the brake pads 442 and the brake disc 443 are fully in contact, the friction between the brake pads 442 and the brake disc 443 restricts the rotation of the brake disc 443, thereby achieving braking of the second clamping component 52.

[0042] When the thrust plate 431 moves upward with the connecting rod 42, the two side walls of the through groove 4311 separate from the top of the brake caliper 441 and no longer abut. The elastic structural member 45 pushes the top of the two brake calipers 441 away from the brake disc 443, so that the brake pad 442 and the brake disc 443 no longer fit together, and the brake disc 443 can rotate with the second clamping member 52.

[0043] In one feasible embodiment, an aluminum alloy heat sink is provided on the outer side of the brake disc 443. The surface of the heat sink is designed with dense heat dissipation fins, which can increase the heat dissipation area by more than 30%. Simultaneously, a rubber dust cover is installed on the outer side of the brake caliper 441 to prevent dust, moisture, and other impurities from entering the brake caliper 441 and affecting braking performance. The dust cover is made of oil-resistant rubber material, possessing elasticity and anti-aging properties.

[0044] Example 3: Continue to refer to Figures 3 to 9 In one feasible embodiment, a first drive mechanism 23 is disposed on a first telescopic arm 21. The first drive mechanism 23 includes a first worm 25 and a first motor 27. A second telescopic arm 22 is provided with a second worm 26. The first worm 25 and the second worm 26 are connected by a synchronizer 24. A worm wheel 28 is disposed inside the synchronizer 24. The first worm 25 and the second worm 26 are respectively disposed on both sides of the worm wheel 28 and mesh with the worm wheel 28. When the first motor 27 drives the first worm 25 to move in a first direction, the first worm 25 pushes the worm wheel 28 to rotate. The worm wheel 28 drives the second worm 26 to move in the first direction, so that the first telescopic arm 21 and the second telescopic arm 22 move synchronously in the first direction.

[0045] Limiting plates (not shown in the figure) are respectively provided on the two side walls of the worm wheel 28 for limiting and guiding the first worm 25 and the second worm 26. The limiting plates limit the first worm 25 and the second worm 26 on the worm wheel 28, thereby preventing misalignment when the first worm 25 and the second worm 26 move.

[0046] A fixed shaft is inserted through the center of the worm gear 28. Both ends of the fixed shaft are fixed to the synchronizer 24, so that the worm gear 28 can rotate around the fixed shaft. The end of the first worm 25 away from the synchronizer 24 is rigidly connected to the first motor 27; the end of the second worm 26 away from the synchronizer 24 is rigidly connected to the second telescopic arm 22.

[0047] The first motor 27 has forward and reverse rotation functions, enabling bidirectional movement of the first worm gear 25. When the first motor 27 rotates forward, it drives the first worm gear 25 to move closer to the synchronizer 24; when the first motor 27 rotates in reverse, it drives the first worm gear 25 to move away from the synchronizer 24, thereby realizing the opening and closing action of the first telescopic arm 21 and the second telescopic arm 22.

[0048] When the first motor 27 drives the first worm 25 to move in the first direction (e.g., to the right), the first worm 25 pushes the worm wheel 28 to rotate clockwise; when the worm wheel 28 rotates, it drives the second worm 26 to move in the opposite first direction (to the left). Due to the synchronicity of the gear meshing, the moving distance of the first worm 25 and the second worm 26 is always equal, ensuring that the first telescopic arm 21 and the second telescopic arm 22 move closer or further away synchronously in the first direction.

[0049] Through the meshing transmission of the worm gear 28 and the coordinated action of the synchronizer 24, the first drive mechanism 23 can realize the synchronous movement of the first telescopic arm 21 and the second telescopic arm 22, providing stable and controllable clamping power for the clamping system 2, and adapting to the clamping requirements of workpieces of different sizes and weights.

[0050] Example 4: Continue to refer to Figure 5 In one feasible embodiment, the lifting system 3 further includes a bracket 33, which is disposed on the base 1, and the second drive mechanism 31 is disposed on the bracket 33.

[0051] In this embodiment, the bracket 33 carries the second drive mechanism 31 and supports the lifting of the clamping system 2. It adopts a frame design. The bottom of the bracket 33 is connected to the base 1 through a fixing plate. The fixing plate has multiple mounting holes, and the bracket 33 is fixed to the base 1 with bolts.

[0052] Example 5: Continue to refer to Figure 10In one feasible embodiment, the second drive mechanism 31 includes a second motor 311 disposed at the top of the bracket 33. The second motor 311 is connected to the clamping system 2 and is used to drive the clamping system 2 to reciprocate along the second direction.

[0053] In this embodiment, the second motor 311 is rigidly connected to the top of the bracket 33. The output shaft of the second motor 311 is connected to the input shaft of the reducer via a flexible coupling.

[0054] The second motor 311 is connected to a ball screw (not shown in the figure). The ball screw is connected to the clamping system 2. The power output by the second motor 311 is first transmitted to the reducer. The output shaft of the reducer is connected to the top of the ball screw through a coupling. A rigid coupling is selected to ensure that the torque output by the second motor 311 can be transmitted to the ball screw without loss.

[0055] A ball screw consists of a screw shaft, a nut, balls, and a reversing device. The screw shaft surface has a helical raceway with a circular arc cross-section, forming four-point contact with the balls to improve load-bearing capacity and motion accuracy. The nut contains a circulating ball circuit, and the reversing device causes the balls to circulate within the nut, converting the rotational motion of the screw shaft into linear motion.

[0056] The top end of the ball screw is supported in a bearing housing at the top of the bracket 33 by a pair of angular contact ball bearings. The bearings are mounted back-to-back, enabling them to withstand both radial and bidirectional axial loads simultaneously. The bottom end of the screw shaft is supported in a bearing housing at the bottom of the bracket 33 by a deep groove ball bearing, which primarily serves a radial positioning function. The bearing housing has a split structure for easy installation and removal of the bearings.

[0057] The ball screw nut is connected to the clamping system 2 via a connecting plate. The connecting plate adopts a box-shaped structure design with internal reinforcing ribs to reduce weight while ensuring strength and rigidity. The connecting plate and the nut are connected by multiple bolts.

[0058] Example 6: Continue to refer to Figure 10 In one feasible embodiment, the clamping and flipping device further includes a clamping system connecting plate 6, a clamping system 2 is disposed on the clamping system connecting plate 6, a first guide rail 34 is disposed on the bracket 33, and a first sliding groove matching the first guide rail 34 is opened on the clamping system connecting plate 6. The clamping system connecting plate 6 is slidably mounted on the first guide rail 34 through the first sliding groove. The second drive mechanism also includes two second cylinders 32, which are symmetrically arranged on both sides of the second motor 311. The two second cylinders 32 are respectively connected to the clamping system connecting plate 6, and are used to drive the clamping system connecting plate 6 to reciprocate along the first guide rail 34 in the first direction.

[0059] In this embodiment, the connecting plate 6 of the clamping system adopts a hollowed-out mesh-like reinforcing rib structure inside, which ensures sufficient rigidity and strength while reducing weight. The first sliding groove is opened on both sides of the connecting plate and adopts a dovetail groove structure design to ensure the fitting accuracy with the first guide rail 34.

[0060] The first guide rail 34 is a rectangular cross-section rolling linear guide rail. The first guide rail 34 is fixed on the vertical mounting surface of the bracket 33. The second cylinder 32 is a double-acting piston cylinder. The two second cylinders 32 are symmetrically arranged on both sides of the second motor 311 and are fixedly connected to the bracket 33 through the cylinder seat. The piston rod end of the second cylinder 32 is hinged to the clamping system connecting plate 6 through a joint bearing, which allows for a certain angular deviation during movement and avoids jamming caused by installation errors.

[0061] Example 7: Continue to refer to Figure 1 In one feasible embodiment, the clamping system connecting plate 6 is provided with a second guide rail 61, and the first telescopic arm 21 and the second telescopic arm 22 are respectively provided with a second sliding groove that matches the second guide rail 61. The first telescopic arm 21 and the second telescopic arm 22 move along the second guide rail 61 in a first direction.

[0062] In this embodiment, the second guide rail 61 adopts a rectangular cross-section linear guide rail to ensure that it matches the second slide groove. The two second guide rails 61 are symmetrically arranged on both sides of the upper surface of the clamping system connecting plate 6. The spacing is designed according to the width of the first telescopic arm 21 and the second telescopic arm 22. The bottom of the first telescopic arm 21 and the second telescopic arm 22 are both provided with a second slide groove that matches the second guide rail 61.

[0063] Example 8: Continue to refer to Figures 1 to 3 In one feasible embodiment, the first clamping component 51 includes a first clamping block 511 and a rotating shaft 512, wherein: the rotating shaft 512 is rotatably mounted on the first telescopic arm 21 and can rotate about its own axis on the first telescopic arm 21; a flipping motor 53 is provided at one end of the rotating shaft 512, and the flipping motor 53 is used to provide rotational power to the rotating shaft 512; the first clamping block 511 is detachably mounted on the other end of the rotating shaft 512 and is used to abut against the workpiece.

[0064] The second clamping component 52 includes a second clamping block 521 and a driven shaft 522, wherein: the driven shaft 522 is rotatably mounted on the second telescopic arm 22 and can rotate about its own axis on the second telescopic arm 22; the second clamping block 521 is detachably mounted on the driven shaft 522, and the second clamping block 521 and the first clamping block 511 abut against the workpiece under the drive of the second telescopic arm 22 and the first telescopic arm 21, respectively, to clamp the workpiece.

[0065] In this embodiment, the rotating shaft 512 is made of structural steel, possessing both strength and toughness, and adapting to the stress conditions during the clamping and flipping of the workpiece. Its two ends are rotatably connected to the first telescopic arm 21 via bearings. The bearings have load-bearing capacity and rotational accuracy, and are installed in pre-machined bearing seats on the first telescopic arm 21. The bearing seats are fixed to the first telescopic arm 21 with bolts, ensuring that the rotating shaft 512 can rotate around its own axis on the first telescopic arm 21.

[0066] The tilting motor 53 is fixed on the first telescopic arm 21. The output shaft of the motor is connected to the rotating shaft 512. The first clamping block 511 is detachably installed on the other end of the rotating shaft 512 by bolts. The end of the rotating shaft 512 is provided with a corresponding threaded hole, and the clamping block is also provided with a matching mounting hole. The clamping block is fixed on the rotating shaft 512 by tightening the bolts.

[0067] The driven shaft 522 is also made of a material with good mechanical properties, similar to the rotating shaft 512 in the first clamping member 51, ensuring that it can rotate about its own axis.

[0068] The structure and function of the second clamping block 521 echo those of the first clamping block 511, and its shape is also designed according to the common shape of the workpiece, so as to clamp the workpiece from different directions when it is used in conjunction with the first clamping block 511. The second clamping block 521 is detachably mounted and fixed to the driven shaft 522 by bolts.

[0069] When the clamping system 2 is working, the first telescopic arm 21 and the second telescopic arm 22 move synchronously in the first direction under the action of the first drive mechanism 23, causing the rotating shaft 512 of the first clamping component 51 and the driven shaft 522 of the second clamping component 52 to move closer to each other. As the two shafts move closer, the first clamping block 511 and the second clamping block 521 gradually come into contact with the workpiece under the drive of their respective shafts, thereby realizing the clamping operation of the workpiece.

[0070] During the clamping process, after the worker completes the current task, the flipping motor 53 starts, driving the first clamping block 511 to rotate via the rotating shaft 512 until it is flipped to a suitable angle. Then, the flipping motor 53 stops, and the workpiece is flipped to an angle suitable for the worker's processing. Simultaneously, reference... Figure 2 The brake disc 443 has a through hole, through which the driven shaft 522 passes and is fixedly connected to the brake disc 443. After the flipping motor 53 flips the workpiece to an angle suitable for the operator to process, the braking system 4 is activated. The brake disc 443 is braked by the brake pads 442, which in turn brakes the driven shaft 522. This ultimately brakes the workpiece held by the first clamping block 511, the second clamping block 521, and the first clamping block 511 and the second clamping block 521, so that the workpiece can be in a suitable angle for the operator to process.

[0071] Meanwhile, since both the first clamping block 511 and the second clamping block 521 are detachable, when faced with workpieces of different types and sizes, the operator can quickly replace the appropriate clamping block and repeat the above operation process to efficiently complete the clamping task of various workpieces, laying the foundation for subsequent lifting and flipping operations.

[0072] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
