Description

Technical Field

[0001] The utility model relates to the field of turnover mechanisms, and more specifically, to a portable turnover mechanism. Background Art

[0002] Currently, when welding workpieces, it is generally necessary to adjust the angle of the workpiece through a turnover mechanism. First, for large or complex-shaped workpieces, during the welding process, the welds at different parts need to be in the best welding position. Through the turnover mechanism, the angle and orientation of the workpiece can be easily adjusted, enabling the welder to perform welding operations in a more comfortable and efficient posture, thereby improving the welding quality and efficiency. Second, some welds may need to be welded from multiple angles. Turning over the workpiece can ensure that the welds at all angles can be fully welded, avoiding incomplete welding or poor quality. Third, the turnover mechanism can make the welding process safer. For example, when welding some high-temperature, high-pressure or dangerous workpieces, turning over can prevent the welder from directly contacting the dangerous area and reduce the risk of accidents. Finally, for batch welding production, the turnover mechanism can quickly and accurately adjust the position of the workpiece, improve the degree of automation and consistency of production, reduce the error of manual operation, and thus ensure the stable quality of the welded product.

[0003] However, the operation of many existing manual turnover mechanisms is rather troublesome. Before and after the operation, it is necessary to perform cumbersome opening and closing operations on some locking devices manually, generally by disassembling and assembling screws or inserting and pulling out plug-in blocks. This is not only troublesome to operate but also inconvenient to do other things during the operation, which undoubtedly increases the complexity and time cost of the operation, resulting in a low degree of convenience and being laborious for single-person operation.

[0004] Therefore, in order to solve the above technical problems, this application proposes a portable turnover mechanism. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a portable turnover mechanism.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A portable turnover mechanism, including two support seats, and the heads of the support seats are both rotatably connected to a turntable through a rotating shaft assembly. A connecting frame is installed between the turntables. A mounting plate is fixedly connected to the surface of the connecting frame. An elastic component for driving the convex block to move upward is arranged on the support seat. A foot pedal capable of pulling the convex block downward is arranged on the elastic component. A plurality of grooves arranged in a circumferential array and for the convex block to insert are formed on the outer side wall of the turntable.

[0007] Preferably, a through groove is formed in the middle of the support base. The elastic component includes a Z-shaped connecting block arranged inside the through groove. One side of the support base is fixedly connected with a hinge piece. The support base is rotationally connected with the Z-shaped connecting block through the hinge piece. The end of the Z-shaped connecting block is connected with the surface of the support base through a spring. The head of the Z-shaped connecting block extends out from the other side of the support base and is fixed to the convex block. The bottom of the convex block is rotationally connected with a pressing rod, and the foot pedal is arranged at the end of the pressing rod.

[0008] Preferably, a cross plate is fixedly connected to the surface of the support base opposite to the pressing rod. A through hole for the pressing rod to pass through is formed inside the cross plate. When the pressing rod moves up and down, it will be restricted by the through hole in the cross plate to maintain its up and down linear movement and prevent it from shifting, so as to avoid interfering with the normal flipping operation of the staff through the foot pedal.

[0009] Preferably, the connecting frame includes an N-shaped connecting platform fixed between two turntables. A cross bar is fixedly connected to the middle of the N-shaped connecting platform. The mounting plate is fixed on the cross bar. Counterweight components are installed at both ends of the N-shaped connecting platform. Reasonably counterweight both sides according to the installed different workpieces to ensure that the weights on both sides are the same, so that the workpiece is more stable during the flipping process.

[0010] Preferably, the counterweight component includes connecting rods fixed to both ends of the N-shaped connecting platform. A baffle is fixedly connected to the head of the connecting rod. Screws are fixedly connected to both the upper and lower sides of the surface of the baffle. A counterweight block is sleeved on the outer side wall of the screw, and a nut is threadedly connected to the outer side wall of the screw.

[0011] Preferably, the foot pedal is detachably connected to the pressing rod through screws and can be detached and replaced when it fails.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. In the present utility model, a fixing tooling for a workpiece or the workpiece is installed on a mounting plate. By stepping on a foot pedal, the elastic component is pressed down, thereby driving the downward movement of a convex block. The convex block moves downward and is pulled out from the initially inserted groove. Then, the angle of the workpiece on the mounting plate can be adjusted by manually rotating a turntable, so as to facilitate welding operations. After the adjustment is completed, the pedal is released, and the elastic component drives the upward movement of the convex block by its elasticity, thereby inserting into the groove corresponding to the angle of the turntable to fix the angle of the workpiece. In this way, the flipping mechanism is convenient to operate. The locking device can be opened and closed by stepping on the foot pedal, and no manual operation is required. The hands can be completely freed up to rotate the workpiece, which is more conducive to single-person operation, so as to solve the problems of troublesome operation, inconvenience in doing other things during operation, undoubtedly increasing the complexity and time cost of operation, resulting in a lower degree of convenience and more laborious single-person operation in the background art;

[0014] 2. The foot pedal of the present utility model is detachably connected to the pressing rod by screws, so that it can be detached and replaced when the foot pedal fails;

[0015] 3. Counterweight components are installed at both ends of the N-shaped connecting platform of the present utility model, so that the two sides can be reasonably counterweighted according to different installed workpieces to ensure that the weights on both sides are the same, making the workpiece more stable during the flipping process.

Detailed implementation manner

[0022] As Figures 1-4 shown, the present utility model provides a portable flipping mechanism, including two support bases 1, and the heads of the support bases 1 are rotatably connected to the turntable 3 through the rotating shaft assembly 2. A connecting frame 4 is installed between the turntables 3. A mounting plate 5 is fixedly connected to the surface of the connecting frame 4. An elastic component 7 for driving the convex block 6 to move upward is arranged on the support base 1. The elastic component 7 is provided with a foot pedal 8 that can pull the convex block 6 downward. A plurality of grooves 9 arranged in a circumferential array and for inserting the convex block 6 are formed on the outer side wall of the turntable 3.

[0023] During use, a fixing tooling (for fixing the workpiece) or the workpiece is installed on the mounting plate 5. By stepping on the foot pedal 8, the elastic component 7 is pressed downward, thereby driving the downward movement of the convex block 6. The convex block 6 moves downward and is pulled out from the initially inserted groove 9. Then, the turntable 3 can be manually rotated (the turntable 3 drives the rotation of the connecting frame 4, and finally drives the rotation of the mounting plate 5), so as to adjust the angle of the workpiece on the mounting plate 5, facilitating welding operations. After the adjustment is completed, the pedal is released, and the elastic component 7 drives the upward movement of the convex block 6 by its elasticity, so as to insert into the groove 9 at the corresponding angle of the turntable 3 to fix the angle of the workpiece. In this way, the flipping mechanism is easy to operate. The locking device can be opened and closed by stepping on the foot pedal 8, and there is no need to operate by hand. The hand can be completely freed up to rotate the workpiece, which is more conducive to single-person operation.

[0024] Furthermore, the foot pedal 8 is detachably connected to the downward pressing rod 704 by screws, so that the foot pedal 8 can be disassembled and replaced when it fails.

[0025] The following is the specific structure of the elastic component 7: A through groove 10 is provided in the middle of the support base 1. The elastic component 7 includes a Z-shaped connecting block 701 disposed inside the through groove 10. One side of the support base 1 is fixedly connected with a hinge 702. The support base 1 is rotationally connected to the Z-shaped connecting block 701 through the hinge 702. The end of the Z-shaped connecting block 701 is connected to the surface of the support base 1 through a spring 703. The head of the Z-shaped connecting block 701 extends out from the other side of the support base 1 and is fixed to the convex block 6. The bottom of the convex block 6 is rotationally connected with a pressing rod 704. The foot pedal 8 is disposed at the end of the pressing rod 704.

[0026] That is, the pressing rod 704 is pressed by stepping on the foot pedal 8. The pressing rod 704 drives the downward movement of the convex block 6 (the connection between the pressing rod 704 and the convex block 6 is a rotational connection to avoid the pressing rod 704 restricting the rotation of the Z-shaped connecting block 701. After all, the convex block 6 and the Z-shaped connecting block 701 are fixed). When the convex block 6 moves downward, it will drive the downward movement of the head of the Z-shaped connecting block 701. The end of the Z-shaped connecting block 701 rotates away from the support base 1, thereby stretching and bending the spring 703. When the pedal is released, the spring 703 starts to reset, thereby resetting the angle of the Z-shaped connecting block 701 and returning to the initial position again (i.e., the position in the attached drawing), so that the convex block 6 moves upward and inserts into the corresponding-angle groove 9 on the disc.

[0027] Moreover, a cross plate 706 is fixedly connected to the surface of the support base 1 opposite to the pressing rod 704. A through hole 705 for the pressing rod 704 to pass through is provided inside the cross plate 706. In this way, when the pressing rod 704 moves up and down, it will be restricted by the through hole 705 on the cross plate 706 to maintain its up-and-down linear movement and avoid its displacement, which may prevent the staff from performing normal flipping operations through the foot pedal 8.

[0028] The connecting frame 4 includes an N-shaped connecting platform 401 fixed between two turntables 3. A cross bar 402 is fixedly connected to the middle of the N-shaped connecting platform 401. The mounting plate 5 is fixed on the cross bar 402. Counterweight assemblies 403 are installed at both ends of the N-shaped connecting platform 401, so that the two sides can be reasonably counterweighted according to the installation of different workpieces, ensuring that the weights on both sides are the same and making the workpiece more stable during the flipping process. The counterweight assembly 403 includes connecting rods 4031 fixed to both ends of the N-shaped connecting platform 401. A baffle 4032 is fixedly connected to the head of the connecting rod 4031. Screws 4033 are fixedly connected to both the upper and lower sides of the surface of the baffle 4032. A counterweight block 4034 is sleeved on the outer side wall of the screw 4033. A nut 4035 is threadedly connected to the outer side wall of the screw 4033. The counterweight block 4034 (with small holes provided on the counterweight block 4034) can be passed through the screw 4033. According to the need, the number of counterweight blocks 4034 inserted into the screws 4033 on both sides is selected. After the insertion is completed, then turn the nut 4035 clockwise to install the nut 4035 on the screw 4033. The nut 4035 slowly abuts against the surface of the outermost counterweight block 4034, so as to cooperate with the baffle 4032 to fix the counterweight block 4034 on the surface of the baffle 4032, so as to complete the installation of an appropriate number of counterweight blocks 4034.
