[0002] Currently, for products with complex structures, where the interior, bottom, and top all require machining, machine tools cannot meet the machining needs of all angles. Therefore, sequential machining is necessary. For example, after machining the interior, the product needs to be flipped 90° before machining the bottom and top. However, flipping the product is difficult in practice, especially for larger and heavier castings. Existing flipping mechanisms have the following main disadvantages: 1. They cannot meet the positioning requirements of different types of products on the flipping mechanism; 2. Different sizes of flipping mechanisms need to be purchased according to the size of the product; 3. Clamping and disassembly waste time; 4. The flipping mechanism occupies a large area, and the product needs to be hoisted back and forth between the flipping mechanism and the machine tool, posing a safety hazard. Utility Model Content

[0017] This utility model provides a universal flipping fixture, which is a mechanism used to complete the product flipping process when the product is being processed in a complex sequence. It mainly aims to solve the problems of existing flipping devices not being applicable to products of various sizes, occupying a large space, and requiring products to be hoisted back and forth between the machine tool and the flipping device, which leads to the products being easily bumped. It enables safer and more efficient flipping operations for a variety of different models and sizes of products.

[0018] Please see Figure 1 This utility model discloses a universal flipping fixture, comprising a flipping fixture body 1, and a first lifting mechanism 21 and a second lifting mechanism 22 arranged side by side above the flipping fixture body 1. This utility model is primarily intended for flipping products 3 with traction holes; wherein, the traction hole is a hole that can be used for traction, and larger and heavier products typically have traction holes near their edges to facilitate lifting and other operations during processing.

[0019] At one end of the flipping fixture body 1 (lower end in the figure), there is a first connecting beam 11 extending to one side (right side in the figure). A fixing pin 13 is provided at the end of the first connecting beam 11 away from the flipping fixture body 1, and the fixing pin 13 matches the traction hole of the product 3. At the other end of the flipping fixture body 1 (upper end in the figure), there is a second connecting beam 12 extending to one side (right side in the figure). The second connecting beam 12 and the first connecting beam 11 are located on the same side of the flipping fixture body 1, and the second connecting beam 12 has a second lifting position 102. On the side of the flipping fixture body 1 facing away from the first connecting beam 11 and the second connecting beam 12 (left side in the figure), there is a first lifting position 101, and the distance between the first lifting position 101 and the fixing pin 13 is less than the distance between the first lifting position 101 and the second lifting position 102.

[0020] The special shape design of the flipping fixture body 1 achieves the following functions: when the traction hole on one edge of the product 3 is vertical, the first connecting beam 11 is horizontal, and the fixing pin 13 is vertical. A clearance space is formed between the fixing pin 13 and the flipping fixture body 1 through the first connecting beam 11. This clearance space also includes a portion of the space between the top of the fixing pin 13 and the second connecting beam 12. The fixing pin 13 can be inserted into the traction hole of the product 3 from bottom to top. The clearance space ensures that the rest of the flipping fixture body 1 (excluding the first connecting beam 11 and the fixing pin 13) will not obstruct the loading and unloading process of the product 3. For ease of installation, the fixing pin 13 and the flipping fixture body 1 can be optionally assembled. Furthermore, the distance of the first lifting position 101 allows the entire assembly to form a specific lever structure, which will be explained later. In the illustrated embodiment, the flipping fixture body 1 is, for example, a C-shaped integral thick plate structure that conforms to the above characteristics. The main part of the second connecting beam 12 is arranged to extend laterally. The fixed end of the second connecting beam 12 preferably also has a section of inclined beam, which helps to ensure that the flipping fixture body is well stressed under load, so that it can bear heavier products. Of course, the flipping fixture body 1 can also adopt other structures that conform to the above characteristics and have sufficient load-bearing strength.

[0021] The lower end of the first lifting mechanism 21 has a controllable lifting first lifting component 201, and the lower end of the second lifting mechanism 22 has a controllable lifting second lifting component 202. The first lifting mechanism 21 and the second lifting mechanism 22 can be selected from existing structures, such as electric hoists or other existing or feasible lifting / transporting mechanisms. Therefore, the lifting structure and other details are not elaborated upon. The first lifting component 201 is rotatably connected to the first lifting position 101, and the second lifting component 202 is rotatably connected to the second lifting position 102.

[0022] Preferably, there are multiple second lifting positions 102 arranged side by side, and the distance between each second lifting position 102 and the fixing pin 13 is different. The second lifting component 202 is detachably connected to each second lifting position 102, so that the connected second lifting positions 102 can be adjusted according to the situation to adjust the lever arm of the lever structure and adjust the center of gravity of the overall structure.

[0023] Furthermore, the first lifting position 101 is located at the end near the first connecting beam 11 (the lower end in the figure). More specifically, the flipping fixture body 1 has a back-side extension 14 on the side facing away from the first connecting beam 11 and the second connecting beam 12, and the back-side extension 14 is located at the end near the first connecting beam 11 (the lower end in the figure), while the first lifting position 101 is located at the end of the back-side extension 14 away from the flipping fixture body 1. This arrangement improves the stress distribution of the overall structure and the resulting lever structure.

[0024] More specifically, both the first lifting component 201 and the second lifting component 202 are provided with connecting pins, which are arranged laterally. Both the first lifting position 101 and the second lifting position 102 are laterally through holes. The first lifting component 201 is rotatably connected by its lower connecting pin passing through the through hole of the first lifting position 101. The second lifting component 202 is rotatably connected by its lower connecting pin passing through the through hole of the second lifting position 102. For example, both the first lifting component 201 and the second lifting component 202 have two plates located on both sides of the flipping fixture body 1. Both plates have pin holes and are connected by connecting pins, thus having sufficient structural strength. In embodiments with multiple second lifting positions 102, the connecting pin of the second lifting component 202 is detachable.

[0025] The first lifting component 201 and the second lifting component 202 can be fixedly formed at the ends of the first and second lifting mechanisms. For ease of practical application and considering the structure of existing lifting mechanisms, the lower ends of the first lifting mechanism 21 and the second lifting mechanism 22 are generally hooks. Therefore, in this solution, both the first lifting component 201 and the second lifting component 202 have lifting rings at the top, which are hung on the hooks. This method is easier to implement; and the entire flip tool body 1 can be removed and stored from the first and second lifting mechanisms, saving space and ensuring safety when idle. Furthermore, for the aforementioned solution where the first and second lifting components are formed by two plates, the lifting rings can be horizontally placed in a D-shape, thus simultaneously connecting and limiting the two plates, resulting in a simpler structure and easier manufacturing.

[0026] The working principle of this utility model is as follows. This universal flipping fixture facilitates rapid flipping during sequential product processing. It primarily utilizes the height difference between two lifting points to achieve the flipping action. Based on the product's traction hole and adjusting the center of gravity, the product is raised while simultaneously lowered to achieve a 90° flipping process, and then stably placed on the worktable. More specifically, during the flipping process, the traction hole position of product 3 is first fixed to the flipping fixture body 1 using fixing pins 13, forming a... Figure 1The state shown is preferably such that the hoisting position and the center of gravity of the product 3 are kept on the same vertical line by adjusting the top hole position (second hoisting position 102); the hoisting position of the first hoisting lifting mechanism 21 is loosened (the first hoisting lifting mechanism 21 is not exerted force), and the hoisting position of the second hoisting lifting mechanism 22 is tightened (the second hoisting lifting mechanism 22 lifts), so that the product 3 rises vertically; after rising to a certain height (creating sufficient space for the product 3 to rotate), it stops, then the hoisting position of the first hoisting lifting mechanism 21 is tightened, and then the hoisting position of the second hoisting lifting mechanism 22 is (gradually) loosened, so that the product 3 rotates under the action of gravity. Figure 1 The rotation is clockwise (rotating clockwise) until the desired angle (usually 90°) is reached and then stops. If product 3 is suspended at this point, the first lifting mechanism 21 and the second lifting mechanism 22 simultaneously descend to lower product 3. Once stabilized, the fixture can be removed from product 3. The position of the first lifting position 101 within the main body of the flipping fixture forms a lever structure, enabling product 3 to flip by its own weight. It is understood that even after a 90° flip, the fixing pin 13, being horizontal or having an assembly connection with product 3, can still support and hold product 3. Therefore, utilizing the universal flipping fixture structure of this invention successfully avoids time wastage caused by flipping, ultimately improving the efficiency of product processing.

[0027] Optionally, the first lifting mechanism 21 and the second lifting mechanism 22 are located on the same movable lifting mechanism; or, the first lifting mechanism 21 and the second lifting mechanism 22 are located on two independent movable lifting mechanisms; or, the first lifting mechanism 21 and the second lifting mechanism 22 are fixedly suspended above the machine tool. This allows for the product 3 to be flipped directly above the machine tool's worktable. Of course, the universal flipping fixture of this invention can also be placed in other locations for flipping in other positions.

[0028] In summary, this utility model's universal flipping fixture can be used for products with traction holes and for products of different sizes and specifications. It is simple to clamp and disassemble, easy to operate, and allows for direct flipping operations on the machine tool station, avoiding product collisions and safety hazards caused by repeated lifting. Preferably, the fixture has multiple holes on its top for adjusting the lifting position to be on the same vertical line as the product's center of gravity, further ensuring stability for different types of products. This solution is simple in structure, safe and efficient, occupies little space, and enables fast and stable flipping. When complex products are processed in stages, the product needs to be flipped 90° so that the upper end of the flipping fixture is on the vertical line of the product's center of gravity, and the lower end is fixed using the product's traction holes. Adjusting the height of the upper and lower ends completes the flipping, accommodating products of different models and sizes. This solution effectively solves the flipping problem when processing different products in stages, saving flipping time while achieving fast and accurate flipping. Furthermore, it saves storage space required for the flipping fixture when not in use.
