The device includes a connecting base, with two sets of fixed plates fixedly connected to the top of the connecting base. A movable rod passes through the interior of each fixed plate, and a movable clamping plate is fixedly connected to the end of the movable rod. Two sets of connecting frames are fixedly connected to the side wall of the fixed plate near the movable clamping plate, and discs are fixedly connected to the opposite sides of the two sets of connecting frames. This adjustable tilt angle clamping and flipping device for metal processing is used in...

[0004] This clamping and flipping device can assist in adjusting the angle of hardware workpieces, thereby improving the applicability of the device. However, in actual use, it was found that the device still has certain defects. First, its tilt angle adjustment is limited by the number of limit slots, and it cannot achieve arbitrary angle adjustment as needed. Second, its adjustment method requires pulling the pull rod and then rotating the angle, and there are four pull rods, which is not easy for a single person to operate. Therefore, improvements are proposed. Utility Model Content

[0022] like Figures 1 to 3 As shown, an adjustable tilting clamping and flipping device is disclosed, comprising a mounting frame 1, a housing 2 fixedly mounted on the inner bottom of the mounting frame 1, a first handwheel 15 provided on one side of the outer surface of the housing 2, a self-locking drive component jointly mounted between the first handwheel 15 and the housing 2, a rotating shaft 4 fixedly mounted on the movable end of the self-locking drive component, the self-locking drive component including a worm gear 17, the worm gear 17 being fixedly connected to the first handwheel 15, the worm gear 17 extending through the outer wall of the housing 2 to the interior and being rotatably connected thereto, the rotatable connection between the worm gear 17 and the housing 2 being connected by a bearing, the inner ring of the bearing being fixedly connected to the worm gear 17, the outer ring of the bearing being fixedly connected to the housing 2, a worm wheel 18 meshing with the outer surface of the worm gear 17, and the worm wheel 18 being fixedly sleeved on the outer surface of the rotating shaft 4, the worm wheel 18 and the worm gear 17 having a self-locking effect, when the worm gear 17 is not rotating, the worm wheel 18 cannot rotate under the action of external force.

[0023] Both ends of the rotating shaft 4 penetrate the inner wall of the housing 2 and extend to the outer side of the mounting bracket 1. The rotating shaft 4 is rotatably connected to the mounting bracket 1. The rotatable connection between the rotating shaft 4 and the mounting bracket 1 is achieved through bearings. The inner ring of the bearing is fixedly connected to the rotating shaft 4, and the outer ring of the bearing is fixedly connected to the mounting bracket 1. Both ends of the rotating shaft 4 are equipped with belt drive assemblies. The output ends of both belt drive assemblies are fixedly connected to splined shafts 8. Both belt drive assemblies include two synchronous pulleys 7, and the two synchronous pulleys 7 are fixedly connected to the adjacent splined shaft 8 and the rotating shaft 4, respectively. Two synchronous pulleys 7 are meshed together by a synchronous belt 13. The synchronous belt 13 and the synchronous pulleys 7 work together to achieve precise power transmission and motion control, ensuring the accuracy and stability of operation. A spline shaft 8 passes through the mounting bracket 1 and is rotatably connected to it. The rotatable connection between the spline shaft 8 and the mounting bracket 1 is achieved by a bearing. The inner ring of the bearing is fixedly connected to the spline shaft 8, and the outer ring of the bearing is fixedly connected to the mounting bracket 1. Spline sleeves 9 are slidably fitted on the outer surfaces of the two spline shafts 8. A clamping plate 11 is fixedly connected to one adjacent end of each of the two spline sleeves 9.

[0024] Both spline sleeves 9 have movable seats 12 rotatably fitted onto their outer surfaces. A bidirectional moving assembly is installed between the two movable seats 12. The bidirectional moving assembly includes a second handwheel 6, which is located on one side of the outer surface of the mounting frame 1. One end of the second handwheel 6 is fixedly connected to a bidirectional screw 10, which passes through the mounting frame 1 and is rotatably connected to it. The rotatable connection between the bidirectional screw 10 and the mounting frame 1 is achieved through a bearing. The inner ring of the bearing is fixedly connected to the bidirectional screw 10, and the outer ring of the bearing is fixedly connected to the mounting frame 1. Two slides 5 are symmetrically threaded onto the outer surface of the bidirectional screw 10, and the slides 5 are fixedly connected to the adjacent movable seats 12. The bidirectional screw 10 drives the two movable seats 12 to move closer or further apart through the slides 5. A slide rail 3 is fixedly connected to both inner walls of the mounting frame 1, and the slides 5 are fixedly connected to the slide rail 3. The slide rail 3 has a limiting function for the slides 5, which can ensure the stability of the movement of the slides 5.

[0025] A scale 16 is fitted onto the outer surface of the worm gear 17, and the scale 16 is fixedly connected to the housing 2. A pointer 14 is fixedly connected to the outer surface of the first handwheel 15, and the pointer 14 matches the scale 16. The rotation angle of the first handwheel 15 can be determined by the cooperation between the scale 16 and the pointer 14.

[0026] Working principle: During use, the entire unit can be installed in the corresponding position on the processing equipment using the mounting bracket 1. The specific installation location depends on the actual processing equipment. During processing, the metal workpiece is placed between the two clamping plates 11. Then, the second handwheel 6 is rotated, which drives the double-acting screw 10 to rotate. The double-acting screw 10 drives the two movable seats 12 to move closer to each other through the slide 5. Then, the spline sleeve 9 drives the clamping plate 11 to move closer to the metal workpiece until clamping is completed. When it is necessary to adjust the processing angle, the first handwheel 15 is rotated, and the adjustment angle is determined by the pointer 14 and the scale 16. The first handwheel 15 drives the worm gear 17 to rotate, which drives the rotating shaft 4 to rotate through the worm wheel 18. The rotating shaft 4 drives the synchronous pulley 7 connected to it to rotate, which then drives the spline shaft 8 to rotate through the synchronous belt 13 and another synchronous pulley 7. The spline shaft 8 drives the spline sleeve 9 and the clamping plate 11 to rotate, thereby driving the metal workpiece to rotate.
