Description

Technical Field

[0001] This utility model relates to the field of flipping machine technology, and in particular to a flipping machine with an adaptive clamping structure. Background Technology

[0002] A flipper is an industrial material handling device used to safely and efficiently adjust the spatial orientation of heavy or large workpieces. Its core function is to securely grip the workpiece using a mechanical clamping mechanism (such as a clamp, hook, or pallet) and drive it to rotate precisely 180 degrees or a specific angle around a horizontal axis. This process allows the workpiece to flip from one side-up to the other, or from a flat position to an upright position, thus adapting to the needs of subsequent processing, assembly, inspection, or welding procedures.

[0003] In the prior art, Chinese utility model patent CN209226076U provides an automatic flipping mechanism. This automatic flipping mechanism is used to automatically flip products to be processed on a conveyor line for processing. It includes a frame, a flipping mechanism for flipping the products, a top-feeding mechanism for feeding the products to the flipping mechanism, and a blocking mechanism for preventing the products from moving forward on the production line. The flipping mechanism is mounted on the frame, the top-feeding mechanism is located below the flipping mechanism, and the blocking mechanism includes a front block and a rear block. The front block is located on one side of the product conveyor line, and the rear block is located on the frame and on one side of the product conveyor line. The automatic flipping mechanism according to this utility model has a simple structure, is easy to manufacture and assemble, improves production efficiency, saves labor costs, and realizes automated production.

[0004] Problems with existing technology: The above-mentioned automatic flipping mechanism cannot adaptively clamp materials of different sizes and with different contact surfaces, resulting in the need to improve the functionality of the automatic flipping mechanism.

[0005] Therefore, there is an urgent need for a flipping machine with an adaptive clamping structure. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a flipping machine with an adaptive clamping structure.

[0007] The technical problem solved by this utility model is achieved through the following technical solution: a flipping machine with an adaptive clamping structure, including a crossbeam, a turntable, a worktable, and a clamping mechanism disposed on one side of the worktable for adaptive clamping of workpieces. The clamping mechanism includes a bidirectional electric push rod A, which is fixed vertically to the worktable by bolts. A bidirectional electric push rod B is fixedly installed horizontally on the worktable. Adjustment plates are fixedly installed on the extended ends of both the bidirectional electric push rod A and the bidirectional electric push rod B. Multiple cylinders are fixedly installed on the outer side of the adjustment plates. A helical spring is fixedly installed at the bottom of the cylinder. A slide rod is fixedly installed at the free end of the helical spring. A ball head is rotatably connected to one end of the slide rod, and a pressing plate is provided at one end of the ball head.

[0008] As a further embodiment of this utility model: a limiting mechanism is provided on one side of the adjusting plate for limiting the workpiece. The limiting mechanism includes an electric push rod, which is fixed to the outer wall of the adjusting plate by bolts. A lifting frame is fixedly installed on the extended end of the electric push rod, and multiple baffles are fixedly installed on one side of the lifting frame.

[0009] As a further embodiment of this utility model: a lifting mechanism is provided at the middle position of the turntable for driving the clamping mechanism to rise and fall. The lifting mechanism includes a drive motor, which is fixed to the outside of the turntable by bolts. A lead screw is fixedly installed at the rotating end of the drive motor, and a lifting block is driven to the outside of the lead screw. The lifting block is fixedly connected to the worktable.

[0010] As a further embodiment of this utility model: a bidirectional electric actuator C is fixedly installed inside the crossbeam, and clamping arms are fixedly installed at both ends of the bidirectional electric actuator C. Limiting rods are slidably connected to both ends of the clamping arms, and a servo motor is fixedly installed at one end of the clamping arm. The rotating end of the servo motor is fixedly connected to the turntable.

[0011] As a further improvement of this utility model, a mounting base is fixedly installed below the crossbeam.

[0012] As a further embodiment of this utility model: a controller is fixedly installed on the outer wall of the crossbeam, and the controller is electrically connected to the bidirectional electric actuator A, bidirectional electric actuator B, bidirectional electric actuator C, drive motor, and servo motor.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. The bidirectional electric actuator A drives the vertical adjustment plates to move closer or further apart. The adjustment plates drive the cylinder to move. Under the elastic support of the helical spring, multiple sliding rods can slide along the cylinder, changing the clamping distance. Under the rotational connection of the ball head, the pressing plate can press at multiple angles. The combination of the two enables the automatic flipping mechanism to adaptively clamp materials of different sizes and with different contact surfaces, enriching the functionality of the automatic flipping mechanism.

[0015] 2. The drive motor drives the lead screw to rotate, and the rotation of the lead screw drives the lifting block to rise and fall, moving the worktable to the other side of the turntable. Subsequently, the servo motor drives the turntable to rotate, which can rotate the worktable to the bottom of the turntable, thereby realizing the automatic flipping of the workpiece and improving the automation level of the flipping machine with adaptive clamping structure.

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] Example 1: As Figure 1-5As shown, a flipping machine with an adaptive clamping structure includes a crossbeam 100, a turntable 200, a worktable 300, and a clamping mechanism disposed on one side of the worktable 300 for adaptive clamping of workpieces. The clamping mechanism includes a bidirectional electric actuator A101, which drives vertical adjustment plates 103 to move closer or further apart. The bidirectional electric actuator A101 is fixed vertically to the worktable 300 by bolts, and the worktable 300 is also bolted horizontally to the bidirectional electric actuator. Rod B102, the extended ends of both the bidirectional electric actuator A101 and the bidirectional electric actuator B102 are fixed with adjusting plates 103 by bolts. The bidirectional electric actuator B102 drives the lateral adjusting plates 103 to move closer or further apart. Multiple cylinders 104 are fixed to the outer side of the adjusting plates 103 by bolts. The adjusting plates 103 drive the cylinders 104 to move. A helical spring 105 is fixed to the bottom of the cylinder 104 by bolts. The free end of the helical spring 105 is fixed with a sliding rod 106 by bolts. Under the elastic support of the helical spring 105, multiple slide rods 106 support the workpiece. One end of each slide rod 106 is rotatably connected to a ball head 107. Under the connection of the ball head 107, a pressing plate 108 is welded to one end of the ball head 107. The pressing plate 108 can rotate in multiple directions, and anti-slip material is pasted on the surface of the pressing plate 108. A limit mechanism is provided on one side of the adjusting plate 103 for limiting the workpiece. The limit mechanism includes an electric push rod 111. The electric push rod 111 is bolted to the outer wall of the adjusting plate 103. The extended end of the electric push rod 111 is bolted to the lifting frame 112. The electric push rod 111 drives the lifting frame 112 to move. Multiple baffles 113 are bolted to one side of the lifting frame 112. The lifting frame 112 drives the multiple baffles 113 to extend to prevent the workpiece from slipping. The mounting base 500 is bolted to the bottom of the crossbeam 100. The rotating machine with the adaptive clamping structure is installed and fixed by the mounting base 500.

[0031] In this embodiment, the bidirectional electric actuator A101 drives the vertical adjustment plates 103 to move closer or further apart. The adjustment plates 103 drive the cylinder 104 to move. Under the elastic support of the helical spring 105, multiple sliding rods 106 can slide along the cylinder 104, changing the clamping distance. Under the rotational connection of the ball head 107, the pressing plate 108 can press at multiple angles. The two work together to enable the automatic flipping mechanism to adaptively clamp materials of different sizes and with different contact surfaces, enriching the functionality of the automatic flipping mechanism.

[0032] Example 2: As Figure 1-5As shown, a flipping machine with an adaptive clamping structure is disclosed. A lifting mechanism is located at the center of the turntable 200 to drive the clamping mechanism to rise and fall. The lifting mechanism includes a drive motor 201, which is bolted to the outside of the turntable 200. A lead screw 202 is bolted to the rotating end of the drive motor 201, causing the lead screw 202 to rotate. A lifting block 203 is connected to the outside of the lead screw 202, and the rotation of the lead screw 202 causes the lifting block 203 to rise and fall. The lifting block 203 is fixedly connected to the worktable 300, thereby causing the worktable 300 to rise and fall along the turntable 200. A bidirectional electric actuator C301 is bolted to the inside of the crossbeam 100. The two ends of the crossbeam 100 are fixed with clamping arms 302 by bolts. The bidirectional electric push rod C301 drives the turntable 200 to move closer or further away from each other through the clamping arms 302 to adjust the clamping distance. The two ends of the clamping arms 302 are slidably connected with limit rods 303. One end of the clamping arms 302 is fixed with a servo motor 304 by bolts. The rotating end of the servo motor 304 is fixedly connected to the turntable 200. The servo motor 304 drives the turntable 200 to rotate. The outer wall of the crossbeam 100 is fixed with a controller 400 by bolts. The controller 400 is electrically connected to the bidirectional electric push rod A101, bidirectional electric push rod B102, bidirectional electric push rod C301, drive motor 201, and servo motor 304. The controller 400 controls the flipping process of the flipping machine.

[0033] In this embodiment, the drive motor 201 drives the lead screw 202 to rotate, and the rotation of the lead screw 202 drives the lifting block 203 to rise and fall, moving the worktable 300 to the other side of the turntable 200. Subsequently, the servo motor 304 drives the turntable 200 to rotate, which can rotate the worktable 300 to the bottom of the turntable 200, thereby realizing the automatic flipping of the workpiece and improving the automation level of the flipping machine with adaptive clamping structure.
