[0002] In the machining of mechanical parts, workpiece positioning is a crucial step in ensuring machining accuracy and quality. Traditional positioning methods often suffer from low efficiency, complex operation, and insufficient positioning accuracy. Furthermore, the positioning device inevitably experiences wear and tear during workpiece contact, requiring repair or even complete replacement, thus significantly increasing the machining cost of mechanical parts. Utility Model Content

[0003] In view of the technical problems in the prior art, the present invention provides a flipping positioning device to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A flipping positioning device includes a mounting plate. Vertical plates perpendicular to the mounting plate are symmetrically arranged on the front and rear sides of the mounting plate. A rotating shaft is fixed between the top left sides of the two vertical plates. A U-shaped positioning block is provided on the rotating shaft. One end of the U-shaped positioning block is rotatably connected to the rotating shaft, and the other end extends upward above the rotating shaft. A positioning element is horizontally and longitudinally arranged inside the U-shaped positioning block. The front and rear ends of the positioning element are fixed to the top of the two vertical plates by bolts. A connecting rod for driving by an external driving device is fixed to the lower front side of the U-shaped positioning block. An abutment is fixed to the upper end of the U-shaped positioning block by bolts.

[0006] Preferably, the positioning component includes a positioning plate arranged horizontally and longitudinally. The front and rear ends of the positioning plate are fixed to the top of the corresponding two vertical plates by bolts. A limiting block is fixed to the lower part of the positioning plate at the corresponding U-shaped positioning block by bolts. When the U-shaped positioning block rotates along the rotation axis to the inner side and abuts against the limiting block, one side of the upper side of the U-shaped positioning block is perpendicular to the horizontal plane.

[0007] Preferably, the abutment includes a vertically arranged positioning rod, and a fixing block is provided on the left side of the positioning rod. The fixing block fixes the positioning rod to the side of one end of the upper side of the U-shaped positioning block by bolts.

[0008] Preferably, the lower end of the positioning rod is fixedly provided with an abutment rod extending downward to the lower left side of one end of the upper side of the U-shaped positioning block. The outer diameter of the abutment rod is smaller than that of the positioning rod, and it is eccentrically set with the positioning rod.

[0009] Preferably, the upper end of the positioning rod extends to the upper side of one end of the U-shaped positioning block, and auxiliary rotation notches are provided on both its front and rear sides.

[0010] Preferably, the mounting plate has a groove at the location corresponding to the U-shaped positioning block, which allows the U-shaped positioning block to abut against it.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This utility model provides a flipping positioning device. First, the device is installed at the workpiece processing area via a mounting plate for positioning. During positioning, the workpiece is positioned by abutting against the abutting rod. The eccentrically set abutting rod can be rotated and finely adjusted through the notch at the upper end of the positioning rod. It is easy to operate, has strong applicability, and only the positioning rod is worn during the abutting process. Moreover, the positioning rod has low cost, which greatly reduces the maintenance cost of the subsequent device and makes it highly practical. At the same time, the flipping design makes it easy for the U-shaped positioning block to rotate along the rotation axis to abut against the groove after the mounting plate is fixed at the processing area, which facilitates the movement of the workpiece from the top.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4This application proposes a flipping positioning device, including a mounting plate 1. Vertical plates 2 perpendicular to the mounting plate 1 are symmetrically arranged on the front and rear sides of the mounting plate 1. A rotating shaft 3 is fixed between the top left sides of the two vertical plates 2. A U-shaped positioning block 4 is provided on the rotating shaft 3. One end of the U-shaped positioning block 4 is rotatably connected to the rotating shaft 3, and the other end extends upward to the top of the rotating shaft 3. A positioning element 5 is arranged horizontally and longitudinally inside the U-shaped positioning block 4. The front and rear ends of the positioning element 5 are fixed to the top of the two vertical plates 2 by bolts. A connecting rod 6 for external driving equipment is fixed on the front side of the lower end of the U-shaped positioning block 4. An abutment 7 is fixed on the upper end of the U-shaped positioning block 4 by bolts. At the same time, the mounting plate 1 has a groove 11 corresponding to the U-shaped positioning block 4 for the U-shaped positioning block 4 to abut.

[0020] Specifically, when machining mechanical parts, the mounting plate 1 of the device is first installed at a suitable position on the parts machining equipment and connected to the connecting rod 6 via an external drive device. This external drive device can be a conventional hydraulic cylinder or pneumatic cylinder, connected in a conventional way to achieve push-pull movement of the connecting rod. When the U-shaped positioning block 4 is driven to rotate along the rotating shaft 3 to abut against the positioning part 5 on the upper side, the upper end of the U-shaped positioning block 4 can abut against the workpiece through the abutment part 7. The abutment part 7 is fixed to the upper end of the U-shaped positioning block 4 with bolts. After wear, only the abutment part 7 needs to be replaced, which greatly reduces the maintenance cost. At the same time, the flip design allows the U-shaped positioning block 4 to rotate downwards and abut against the groove 11, so that it will not affect the movement of the upper workpiece.

[0021] Further details can be found here. Figure 1-3 The positioning component 5 includes a horizontally longitudinally arranged positioning plate 51. The front and rear ends of the positioning plate 51 are fixed to the top of the corresponding two vertical plates 2 by bolts. A limiting block 52 is fixed to the U-shaped positioning block 4 below the positioning plate 51 by bolts. When the U-shaped positioning block 4 rotates along the rotation axis 3 to the inner side and abuts against the limiting block 52, the setting of the limiting block 52 here can ensure that the upper side of the U-shaped positioning block 4 is perpendicular to the horizontal plane, so as not to affect the abutment of the workpiece. At the same time, the limiting block 52 and the positioning plate 51 are both fixed by bolts, and the worn parts are all connected by threads, which facilitates the corresponding replacement and further reduces maintenance costs.

[0022] Further details can be found here. Figure 1 , 4The abutment member 7 includes a vertically arranged positioning rod 71. A fixing block 72 is provided on the left side of the positioning rod 71. The fixing block 72 fixes the positioning rod 71 to the side of one end of the upper side of the U-shaped positioning block 4 by bolts. An abutment rod 73 is fixedly provided at the lower end of the positioning rod 71, extending downward to the lower side of the left side of one end of the upper side of the U-shaped positioning block 4. The outer diameter of the abutment rod 73 is smaller than that of the positioning rod 71, and it is eccentrically set with the positioning rod 71. By rotating the entire positioning rod 71, the abutment position of the abutment rod 73 can be changed, thereby realizing the fine adjustment of the abutment. On the one hand, it can cope with the wear at the abutment rod 73. On the other hand, the eccentric setting facilitates the fine adjustment of the abutment distance, making the abutment more precise.

[0023] Meanwhile, the upper end of the positioning rod 71 extends to the upper side of one end of the U-shaped positioning block 4, and notches 74 are provided on its front and rear sides to assist the rotation of the positioning rod 71 and facilitate adjustment.
