[0001] This utility model relates to the field of tooling fixture technology, specifically a tooling fixture that is easy to flip and position. Background Technology

[0002] Work fixtures, often simply called clamps, are auxiliary tools widely used in the manufacturing industry. They are special devices used in the manufacturing process to quickly and accurately position and fix workpieces. They integrate functions such as workpiece positioning, support, clamping, and tool guiding mechanisms to ensure that the workpiece maintains a stable position and posture during processing, inspection, or assembly.

[0003] Most fixtures used in machining currently lack good flipping and positioning functions, requiring the fixture to be released before the part can rotate during machining. Furthermore, most fixtures are designed for parts of a single size, resulting in poor practicality. Utility Model Content

[0008] As a further preferred embodiment of this technical solution, a baffle is fixedly connected to the top of the polygonal connecting column, and one end of the movable ring is interference-fitted with the interior of the fixed seat.

[0009] As a further preferred embodiment of this technical solution, each of the four driven rods has a limiting plate fixedly connected to its other end, and the outer surface of the four limiting plates is in contact with one side of the partition plate.

[0010] As a further preferred embodiment of this technical solution, a limiting ring is fixedly connected to the outer surface of the adjusting column, the outer surface of the limiting ring can abut against one side of the partition plate, and friction texture is formed on the inner surface of the fixed plate.

[0012] This utility model provides a tooling fixture that is easy to flip and position, and has the following beneficial effects:

[0013] (1) This utility model uses an adjusting gear to drive the adjusting column to move, so that the adjusting column drives the connecting rod to rotate during the movement. During the rotation of the connecting rod, the four driven rods are pulled to retract, so that the fixed plate retracts to position and clamp the mechanical parts. It can position and clamp mechanical parts of different sizes. When it is necessary to flip the parts, it is only necessary to adjust the rotating seat, so that the processing of mechanical parts is more convenient, the work efficiency is improved, and the practicality is strong.

[0014] (2) This utility model moves the limiting rod inside the adjusting seat by dragging it, so that one end of the limiting rod exits from the fixed tooth ring. Then, the rotating seat is rotated to make the mechanical parts rotate to the designated position. After reaching the designated position, the operator releases the limiting rod, and the pressure spring restores its elastic deformation to push the limiting rod into the tooth groove of the fixed tooth ring to quickly fix the rotating seat. The structure is simple, the fixing is convenient, and the efficiency of flipping mechanical parts is improved. Attached Figure Description

[0021] This utility model provides a technical solution: such as Figure 1-3 As shown in this embodiment, a tooling fixture for easy flipping and positioning includes a mounting base 1, a rotating base 2 rotatably connected inside the mounting base 1, a partition plate 3 fixedly connected inside the rotating base 2, four guide holes 4 penetrating one end of the rotating base 2 and one side of the partition plate 3, four driven rods 5 slidably connected inside the four guide holes 4, two connecting rods 6 rotatably connected inside the four driven rods 5, and an adjusting column 7 rotatably connected to the other end of the eight connecting rods 6. The outer surface of the adjusting column 7 is slidably connected to the inside of the partition plate 3, a bearing seat 9 is fixedly connected to the inner surface of the rotating base 2, an adjusting gear 10 is rotatably connected inside the bearing seat 9, and the outer surface of the adjusting gear 10 meshes with the outer surface of the adjusting column 7. A fixing plate 8 is fixedly connected to one end of each of the four driven rods 5. The guide holes 4 can guide the movement of the driven rods 5, and the connecting rods 6 can drive the driven rods 5 to move during the movement of the adjusting column 7.

[0022] like Figure 1 and Figure 4 As shown, a fixed toothed ring 18 is fixedly connected to the outer surface of the rotating seat 2, and an adjusting seat 19 is fixedly connected to one side of the mounting seat 1. A limiting rod 20 is slidably connected inside the adjusting seat 19. One end of the limiting rod 20 is engaged with any tooth groove on the outer surface of the fixed toothed ring 18. By setting the limiting rod 20, the rotating seat 2 can be fixed by cooperating with the fixed toothed ring 18.

[0023] like Figure 3 As shown, one end of the adjusting gear 10 passes through the inner surface of the rotating seat 2 and is fixedly connected to a polygonal connecting post 11. A movable ring 12 is slidably connected to the outer surface of the polygonal connecting post 11. One end of the movable ring 12 is inserted into a fixed seat 13. One end of the fixed seat 13 is fixedly connected to the outer surface of the rotating seat 2, which can fix the adjusting gear 10 and make the fixed plate 8 clamp more stably.

[0024] like Figure 2 and Figure 3As shown, a baffle 14 is fixedly connected to the top of the polygonal connecting column 11, and one end of the movable ring 12 is interference-fitted with the inside of the fixed seat 13. By setting the baffle 14, the movable ring 12 can be prevented from falling off.

[0028] This utility model provides a tooling fixture that is easy to flip and position. The specific working principle is as follows:

[0029] When clamping and positioning mechanical parts, the operator inserts one end of the part between the fixed plates 8, then pulls the movable ring 12 out from the fixed seat 13, rotates the movable ring 12 to drive the adjusting gear 10 to rotate, the adjusting gear 10 drives the adjusting column 7 to move, so that the adjusting column 7 drives the connecting rod 6 to rotate during the movement, and the connecting rod 6 pulls the four driven rods 5 to retract during the rotation, so that the fixed plate 8 retracts to position and clamp the mechanical part. When it is necessary to flip the mechanical part, the operator drags the limit rod 20 to move inside the adjusting seat 19, so that one end of the limit rod 20 exits from the fixed toothed ring 18, and then rotates the rotating seat 2 to rotate the mechanical part to the designated position. After reaching the designated position, the operator releases the limit rod 20, the pressure spring 21 restores its elastic deformation and pushes the limit rod 20 into the tooth groove of the fixed toothed ring 18 to quickly fix the rotating seat 2.
