Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment technology, specifically a metal surface treatment clamping mechanism. Background Technology

[0002] In the field of metal surface treatment technology, when processing metal parts, it is often necessary to use a clamping mechanism to fix the metal parts to ensure the stability and accuracy of the processing. However, existing clamping mechanisms have many shortcomings in practical applications:

[0003] Traditional clamping mechanisms can usually only fix metal parts of a specific size or shape. For cylindrical metal parts of different diameters or rectangular metal parts of different specifications, different clamping components need to be replaced, which is cumbersome and inefficient.

[0004] When the top and bottom of a metal part need to be processed simultaneously, existing mechanisms often require multiple disassembly and reassembly of the metal part and adjustment of its posture. This not only increases the number of operation steps, but may also cause processing errors due to repeated positioning, affecting the processing quality.

[0005] According to the description of a metal surface treatment clamping mechanism published on the patent website (authorization announcement number: CN222177411U), the metal surface treatment clamping mechanism includes "support rotation component, clamping and fixing component", etc., to realize the clamping work.

[0006] Regarding the above description, the applicant believes the following issues exist:

[0007] This metal surface treatment clamping mechanism uses a supporting rotating component and a clamping fixing component to achieve clamping work. In use, the metal parts are fixed by clamping plates. However, the rectangular clamping plates cannot guarantee the stability when fixing cylindrical metal parts. Moreover, the mechanism is driven by gears and racks, and the debris generated during processing can enter these devices, affecting the accuracy of the drive and potentially causing jamming. Therefore, this mechanism needs to be improved. Utility Model Content

A slide rail is fixedly connected to the bottom of the movable seat, and the slide rail is slidably connected to the top of the processing table and the inside of the load-bearing frame. The slide rail is located at the top of the support mechanism. A servo motor is fixedly connected to the left side of the fixing bracket, and a rotating rod is fixedly connected to the left side of the servo motor. A mounting bracket is fixedly connected to the left side of the rotating rod, and a fixing rod is rotatably connected inside the mounting bracket.

[0012] Preferably, the rotating rod is rotatably connected inside the fixed frame, the mounting frame is rotatably connected to the inside of the processing table, the disc is located at the front of the mounting frame and its bottom is flush with the bottom of the mounting frame, and the rear side of the fixed shaft passes through the inside of the mounting frame, so as to ensure the stability between the disc and the fixed rod and the mounting frame through the fixed shaft.

[0013] Preferably, the first limiting frame and the second limiting frame are V-shaped and rectangular, respectively, and rubber pads are provided on the inner side of the first limiting frame and the inner side of the second limiting frame, so as to facilitate the fixing of metal parts of different shapes through the first limiting frame and the second limiting frame.

[0014] Preferably, the load-bearing frame, the first hydraulic cylinder, the guide rod, the fixed frame, the moving seat, the slide rail, the servo motor, the rotating rod, the mounting frame, the fixed rod, the fixed seat, the first limiting frame, the second limiting frame, the disc, and the fixed shaft are arranged in two sets and symmetrically distributed on the left and right sides of the top of the processing table, so as to facilitate the fixing of metal parts of different sizes by setting two sets.

[0018] 1. This metal surface treatment clamping mechanism, through its fixed mechanism, allows for the treatment of both the top and bottom of a cylindrical metal part. The metal part is positioned within two sets of first limiting frames. A first hydraulic cylinder drives the fixed frames to move, and the guide rods and slide rails adjust the spacing between the first limiting frames to accommodate metal parts of different sizes. A servo motor drives a rotating rod, which in turn rotates the mounting frame, the fixed base, and the fixed metal part, enabling simultaneous treatment of both the top and bottom of the metal part. This eliminates the need for frequent disassembly and reassembly, reducing operational steps. The threaded connection between the fixed shaft and the disc allows for quick fixing or loosening of the fixing rod, facilitating the switching of the positions of the first and second limiting frames according to processing requirements, further enhancing operational flexibility. The second limiting frame is particularly useful for fixing rectangular metal parts.

[0019] 2. The metal surface treatment clamping mechanism, through the set support mechanism, drives the placement table to move up and down by the second hydraulic cylinder, so that the top of the placement table is flush with the top of the processing table, which can support the bottom of the metal part fixed inside the first or second limit frame, enhance the stability of the workpiece during processing. The moving groove and sliding groove on the top of the placement table correspond to each other, which does not affect the normal sliding of the fixing mechanism and ensures the coordination of the overall structure operation.

A first limiting bracket 393 is fixedly connected to the left side of the fixed seat 392. A second limiting bracket 394 is fixedly connected to the right side of the fixed seat 392. A disc 395 is fixedly connected to the front side of the fixed rod 391. A fixed shaft 396 is threadedly connected inside the disc 395.

[0034] The guide rod 33 is slidably connected to the inside of the load-bearing frame 31. The top of the processing table 2 and the inside of the load-bearing frame 31 are respectively provided with sliding grooves, and the two sliding grooves correspond to each other, so as to ensure the stability of the fixed frame 34 when it moves through the guide rod 33.

[0035] The rotating rod 38 is rotatably connected to the inside of the fixed frame 34, the mounting frame 39 is rotatably connected to the inside of the processing table 2, the disc 395 is located on the front side of the mounting frame 39 and its bottom is flush with the bottom of the mounting frame 39, and the rear side of the fixed shaft 396 passes through the inside of the mounting frame 39, so as to ensure the stability between the disc 395 and the fixed rod 391 and the mounting frame 39 through the fixed shaft 396.

[0036] The first limiting frame 393 and the second limiting frame 394 are V-shaped and rectangular, respectively, and rubber pads are provided on the inner side of the first limiting frame 393 and the inner side of the second limiting frame 394, so as to facilitate the fixing of metal parts of different shapes through the first limiting frame 393 and the second limiting frame 394.

[0037] The load-bearing frame 31, the first hydraulic cylinder 32, the guide rod 33, the fixed frame 34, the moving seat 35, the slide rail 36, the servo motor 37, the rotating rod 38, the mounting frame 39, the fixed rod 391, the fixed seat 392, the first limiting frame 393, the second limiting frame 394, the disc 395, and the fixed shaft 396 are provided in two sets and symmetrically distributed on the left and right sides of the top of the processing table 2, so as to facilitate the fixing of metal parts of different sizes by setting two sets.

[0038] Example 2

[0039] Please see Figure 1-6Furthermore, based on Embodiment 1, the support mechanism 4 further includes a support frame 41, which is fixedly connected to the bottom of the processing table 2. A second hydraulic cylinder 42 is fixedly connected to the bottom of the support frame 41, and a placement table 43 is fixedly connected to the top of the second hydraulic cylinder 42. Movable frames 44 are fixedly connected to the left and right sides of the bottom of the placement table 43, and the movable frames 44 are slidably connected to the inside of the support frame 41.

[0040] The placement table 43 is slidably connected inside the processing table 2, so that the placement table 43 can further support the bottom of the metal part.

[0041] In actual operation, when this device is used, when it is necessary to process the top and bottom of the metal part and the metal part is cylindrical, the second hydraulic cylinder 42 drives the placement table 43 to move up and down, so that the top of the placement table 43 is flush with the top of the processing table 2. When the placement table 43 moves, it will drive the moving frame 44 to slide inside the support frame 41, ensuring the stability of the placement table 43 when it moves.

[0042] At this point, the metal part can be placed at the center of the top of the placement table 43, inside the two sets of first limiting frames 393. The first hydraulic cylinder 32 drives the fixed frame 34 to move. When the fixed frame 34 moves, it will drive the guide rod 33 to slide inside the load-bearing frame 31. At the same time, the moving seat 35 drives the slide rail 36 to slide on the top of the processing table 2 and inside the load-bearing frame 31 to ensure stability during movement. The fixed frame 34 drives the mounting frame 39, the fixed seat 392 and the first limiting frame 393 to move to the left and right sides of the metal part to fix it. At the same time, the placement table 43 supports the bottom of the metal part to ensure the stability of the metal part during processing.

[0043] When the bottom of the metal part needs to be processed, the placement table 43 is first moved to the bottom of the processing table 2 under the action of the second hydraulic cylinder 42 without affecting the rotation of the metal part. At this time, the servo motor 37 can drive the rotating rod 38 and the mounting bracket 39 to rotate, which can drive the fixed seat 392 and the fixed metal part to rotate, so as to process the top and bottom of the metal part at the same time. There is no need to frequently disassemble and reassemble, reducing the operation steps. After flipping, the bottom of the metal part can be supported again under the action of the placement table 43.

[0044] When the metal part to be processed is rectangular, remove the fixed shaft 396, so that the disc 395 drives the fixed rod 391 and the fixed seat 392 to rotate, and the positions of the first limit frame 393 and the second limit frame 394 are interchanged. The disc 395 and the mounting frame 39 are fixed by the fixed shaft 396 to ensure the stability of the fixed rod 391, so that the rectangular metal part can be processed.

[0045] The size of the metal parts processed by this device cannot be larger than the size of the placement table 43, and the minimum size can only be inside the initial position of the two sets of first limit frames 393. In use, all the first hydraulic cylinders 32, second hydraulic cylinders 42 and servo motors 37 need to be connected to the same PLC controller to ensure the coordinated operation of the equipment. The PLC controller is existing technology, and those skilled in the art know its operation method. It will not be described in detail in this case.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
