Description

Technical Field

[0001] This utility model relates to the field of flipping mechanism technology, and in particular to a mechanism that can realize flipping action. Background Technology

[0002] When machining a workpiece, it is necessary to flip the workpiece so that different end faces can be machined.

[0003] In existing technologies, workpieces are typically clamped and fixed by a worker using a fixture. However, this only allows processing of the upward-facing end face. When different end faces of the workpiece need to be processed, the workpiece must be removed from the fixture and flipped at an appropriate angle to be clamped and fixed again for processing. However, operating the fixture is time-consuming, and the workpiece loading and unloading process results in low processing efficiency. To solve these problems, this application proposes a mechanism that enables the flipping action. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a mechanism that can realize the flipping action. It can clamp and fix the workpiece through the limiting mechanism, and flip the clamped workpiece to a suitable angle through the motor to perform processing operations on different end faces of the workpiece.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1 A device capable of flipping includes a frame 1. Two fixed plates 2 are fixedly connected to the top of the frame 1. Rectangular frames 3 are fixedly connected to opposite ends of the two fixed plates 2. A worm gear 9 is rotatably connected to each rectangular frame 3. Each worm gear 9 is engaged with a worm wheel 10. The self-locking property of the worm gear and worm wheel ensures that the flipping can stop at any angle. A rotating rod 11 is coaxially fixedly connected to each worm wheel 10. Each rotating rod 11 passes through the corresponding rectangular frame 3 and fixed plate 2 and is rotatably connected to them. A flipping frame 12 is fixedly connected to the opposite ends of the two rotating rods 11. A power motor 18 is fixedly connected to the side wall of the rectangular frame 3. The output end of the power motor 18 is fixedly connected to the worm gear 9.

[0025] Example 2

[0026] Reference Figures 2-3 This embodiment differs from Embodiment 1 in that, in this embodiment, the tops of the two rectangular frames 3 are jointly and fixedly connected to a U-shaped plate 4, and the rear end of the U-shaped plate 4 is fixedly connected to a motor 5. Two rotating rods 6 are rotatably connected to the U-shaped plate 4. The rotating rod 6 on the right side is fixedly connected to the output end of the motor 5. The two rotating rods 6 are jointly fitted with a first pulley belt 7. The outer walls of the two rotating rods 6 are fixedly connected to first pulleys. The first pulley belt 7 is fitted on the outer walls of the two first pulleys. The outer wall of each worm 9 and the outer wall of its corresponding rotating rod 6 are respectively fitted with a second pulley belt 8. The outer wall of the rotating rod 6 is fixedly connected to a driving pulley, and the outer wall of the worm 9 is fixedly connected to a driven pulley. The second pulley belt 8 is fitted on the outer walls of the driving pulley and the driven pulley. The motor 5 can drive the two worm 9 to rotate synchronously, so that the two flipping frames 12 can flip synchronously.

[0027] Each flipping frame 12 is equipped with a limiting mechanism, which includes two connecting plates 13 fixedly connected to the flipping frame 12. Hydraulic rods 14 are fixedly connected to the opposite ends of the two connecting plates 13, and clamping plates 15 are fixedly connected to the opposite ends of the two hydraulic rods 14. The workpiece can be clamped and fixed by moving the clamping plates 15 on both sides relative to each other through the hydraulic rods 14.

[0028] The bottom of the frame 1 is fixedly connected to four support mechanisms. Each support mechanism includes a fixing screw 16 fixedly connected to the bottom of the frame 1. The outer wall of the fixing screw 16 is fitted with a hollow support cylinder 17 that is threadedly connected to it. The bottom of the hollow support cylinder 17 is provided with anti-slip texture. The hollow support cylinder 17 can be adjusted by rotating it, so that the device can be stably supported on the ground and kept horizontal.

[0029] In this invention, the worker places the workpiece between two flipping frames 12 and activates four hydraulic rods 14. Two hydraulic rods 14 on the same side extend and move the clamping plates 15. The workpiece can be clamped and fixed by the clamping plates 15 on both sides. The motor 5 is activated, and the output end of the motor 5 drives the rotating rod 6 on the right, the first pulley 7, and the rotating rod 6 on the left to rotate. The synchronous rotation of the two rotating rods 6 drives the second pulley 8, the worm gear 9, the worm wheel 10, the rotating rod 11, the flipping frame 12, and the clamped and fixed workpiece to flip. The clamped and fixed workpiece can be flipped from 0 to 360 degrees with the rotating rod 11 as the rotation center. The workpiece can be freely flipped to any angle, which meets the needs of workpiece transmission and flipping.

[0030] This invention, by setting a limiting mechanism and a motor, can rotate the clamped workpiece to a suitable angle, solving the problem of existing technology where workers operate fixtures to clamp and fix the workpiece, but only the upward-facing end face can be processed. When different end faces of the workpiece need to be processed, the workpiece needs to be removed from the fixture and rotated to a suitable angle so that it can be clamped and fixed again to process different end faces of the workpiece. However, operating the fixture requires a lot of time, and the workpiece loading and unloading results in low workpiece processing efficiency.
