The clamping assembly 3 is disposed on the upper surface of the worktable 1 by means of the support assembly 4, and the support assembly 4 is located on the upper surface of the worktable 1.

[0034] In the embodiments of this utility model, please refer to Figure 3 and Figure 4The clamping assembly 3 includes a clamp base 301 with a U-shaped cross-section. A mounting base 302 is fixedly connected to the inner wall of the clamp base 301. A cylinder 303 is fixedly connected to the inner wall of the mounting base 302. A connecting plate 304 is fixedly connected to the output end of the cylinder 303. An adjusting plate 305 is fixedly connected to the side of the connecting plate 304 away from the cylinder 303. The adjusting plate 305 has an isosceles trapezoidal cross-section. Sliding holes 306 are provided on both inclined sides of the adjusting plate 305. A sliding plate 307 is slidably connected to the inner wall of the sliding hole 306. A connecting element is fixedly connected to the upper surface of the sliding plate 307. Plate 308, with clamping plates 309 fixedly connected to the sides of two connecting plates 308 that are close to each other, and airbags 310 fixedly connected to the sides of two clamping plates 309 that are close to each other. A connecting pipe 311 is fixedly connected to the upper surface of the airbag 310. A cylinder 314 is fixedly connected to the inner wall of the clamping base 301, and a piston 313 slides on the inner wall of the cylinder 314. A connecting rod 312 is fixedly connected to one side of the piston 313. The connecting rod 312 is fixedly connected to the side of the connecting plate 304 near the cylinder 303. The end of the connecting pipe 311 away from the airbag 310 is fixedly connected to the outer wall of the cylinder 314. By setting the clamping assembly 3, the airbags 310 can be inflated simultaneously while the clamp is holding precision parts, thereby improving the flexibility of the clamp, preventing damage to the parts, and improving the practicality of the clamping device. A positioning hole 315 is provided on the upper surface of the clamp base 301. A positioning block 316 is slidably connected to the inner wall of the positioning hole 315, and the positioning block 316 is fixedly connected to the lower surface of the clamping plate 309. When the connecting plate 308 moves the clamping plate 309, the positioning block 316 fixed on the clamping plate 309 will slide along the inner wall of the positioning hole 315, thereby improving the stability of the clamping plate 309 during movement. A limiting ring 317 is sleeved on the outside of the connecting pipe 311. The limiting ring 317 has a "U" shaped cross-section and is fixed to the upper surface of the clamping plate 309. The limiting ring 317 can restrain and limit the connecting pipe 311, thereby minimizing the risk of the connecting pipe 311 becoming entangled. The connecting pipe 311 is designed as a corrugated pipe. Corrugated pipes have good flexibility, are pressure-resistant and shock-resistant, and adaptable to thermal expansion and contraction.

[0035] In the embodiments of this utility model, please refer to Figure 5 and Figure 6The support assembly 4 includes a fixed base 41, which is fixed to the upper surface of the worktable 1. Two rotating shafts 42 are rotatably mounted on the inner wall of the fixed base 41. The ends of the two rotating shafts 42 that are close to each other are fixedly connected to the two sides of the clamping base 301, respectively. A connecting rod 43 is rotatably connected to the centrifugal position of one of the rotating shafts 42 away from the clamping base 301. A welding plate 44 is fixedly connected to the upper surface of the fixed base 41. An electric actuator 45 is fixedly connected to one side of the short arm end of the welding plate 44. The output end of the electric actuator 45 is rotatably connected to one end of the connecting rod 43. By setting up the support assembly 4, after the part is firmly clamped by the clamping assembly 3, the flipping angle of the part can be automatically adjusted, which improves the machining accuracy and efficiency of the part, while reducing manual intervention and operational errors. An arc-shaped hole 46 is provided on the side of the fixed base 41 away from the connecting rod 43. The center of the arc-shaped hole 46 is coaxial with the rotation axis of the fixture base 301. A slide rod 47 is slidably connected to the inner wall of the arc-shaped hole 46, and one end of the slide rod 47 is fixedly connected to one side of the outer wall of the fixture base 301. When the fixture base 301 rotates, the slide rod 47 fixed to one side of the fixture base 301 will slide along the inner wall of the arc-shaped hole 46, thereby improving the stability of the fixture base 301 during rotation. An adjusting ring 48 is threadedly connected to the arc surface of the slide rod 47, and the adjusting ring 48 abuts against one side of the fixed base 41. When the fixture base 301 drives the part to rotate to a suitable angle, rotating the adjusting ring 48 to abut against the fixed base 41 can lock the fixture base 301.

[0036] The working principle of the quick positioning fixture device for precision parts machining provided by this utility model is as follows: When it is necessary to use the device to clamp and position precision parts, the part to be processed is first placed in the middle position above the fixture base 301. Then, the cylinder 303 is activated to drive the connecting plate 304 to move. The connecting plate 304 drives the adjusting plate 305. The adjusting plate 305 drives the sliding plate 307 through the sliding holes 306 on its two inclined sides, so that the two sliding plates 307 move towards each other at the same time. The sliding plates 307 drive the connecting plate 308, connecting... The plate 308 moves the clamping plate 309 until the clamping plate 309 moves the airbag 310 to firmly clamp the part. Simultaneously, the connecting plate 304 moves, causing the connecting rod 312 to move closer to the cylinder 314. The connecting rod 312 drives the piston 313, causing the piston 313 to move along the inner wall of the cylinder 314. At this time, the gas inside the cylinder 314 is driven by the piston 313 into the connecting pipe 311. The gas then enters the airbag 310 through the connecting pipe 311, thus inflating the airbag 310 and raising the clamping plate 308. The flexibility on one side prevents the clamping plate 309 from damaging the part. After the part is processed, the cylinder 303 is activated to move the connecting plate 304 in the opposite direction. The connecting plate 304 then moves the adjusting plate 305 in the opposite direction. The adjusting plate 305 drives the sliding plate 307 in the opposite direction via the sliding hole 306. The sliding plate 307 moves the clamping plate 309. When the clamping plate 309 separates from the part, the part can be removed from the fixture seat 301. While the connecting plate 304 moves, the piston 313 moves in the opposite direction along the inner wall of the cylinder 314, thereby enabling the airbag 310 to move in the opposite direction. The internal gas is extracted to prevent the airbag 310 from being in an inflated state for a long time and causing gaps. When the connecting plate 308 moves the clamping plate 309, the positioning block 316 fixed on the clamping plate 309 will slide along the inner wall of the positioning hole 315, thereby improving the stability of the clamping plate 309 during movement. In addition, the limiting ring 317 can restrain and limit the connecting pipe 311, thereby minimizing the possibility of the connecting pipe 311 getting tangled. Finally, by setting the connecting pipe 311 as a corrugated pipe, the corrugated pipe has good flexibility, pressure resistance and shock resistance, and adaptability to thermal expansion and contraction.

[0037] When the fixture seat 301 needs to be rotated and adjusted, the cylinder 303 is first started to drive the connecting rod 43 to rotate. The connecting rod 43 drives the rotating shaft 42 to rotate along the inner wall of the fixed seat 41. The rotating shaft 42 drives the fixture seat 301 to rotate. When the fixture seat 301 drives the precision parts to rotate, the operation of the electric push rod 45 can be stopped after the rotation reaches a suitable angle. Finally, the adjusting ring 48 is rotated to abut against the fixed seat 41 to lock the fixture seat 301. When the fixture seat 301 rotates, the slide rod 47 fixed on one side of the fixture seat 301 will slide along the inner wall of the arc-shaped hole 46, thereby improving the stability of the fixture seat 301 during rotation.

[0038] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
