[0002] Precision parts are components that require extremely high dimensional accuracy, surface finish, and shape precision during manufacturing. They are typically used in demanding industries such as aerospace, automotive manufacturing, electronics, and medical devices. Manufacturing precision parts requires high-precision machining equipment, such as CNC machine tools, laser cutting machines, and precision milling machines, and usually utilizes high-performance materials such as stainless steel, aluminum alloys, and titanium alloys.

[0003] While existing vacuum chucks can effectively clamp and fix precision parts during use, they can only keep the precision parts in a horizontal position during machining, which is not conducive to the normal progress of machining work and affects the machining of parts. Utility Model Content

[0012] This utility model provides a vacuum chuck for precision parts, which has the following advantages:

[0013] (1) By pulling the handle, the handle drives the limiting block to move downward. As the limiting block moves downward, it releases the first gear from its restriction.

At this time, the slider disengages from the limit and pushes the slider. The slider moves inside the slide rail, and the slider drives the moving inner rod to move inside the fixed rod. The moving inner rod drives the vacuum suction cup body to move, thereby adjusting the position of the precision parts. Attached Figure Description

[0027] The outer wall of the limiting block 410 is fixedly connected to a handle 411, and the bottom end of the movable block 49 is fixedly connected to a spring 48. The end of the spring 48 away from the movable block 49 is fixedly connected to the bottom end of the movable groove 47.

[0028] Spring 48 provides support to movable block 49 by means of its own elasticity.

[0029] The outer wall of the fixed rod 41 is provided with a limit mechanism 5, and a slide rail 51 is provided on the outer wall of the fixed rod 41. A slider 52 is slidably connected to the inner wall of the slide rail 51.

[0030] The limiting mechanism 5 can limit the extension and retraction length of the movable inner rod 42.

[0031] One end of the slider 52 is fixedly connected to the outer wall of the movable inner rod 42, and the other end of the slider 52 has a cavity 53, with a rotating shaft 54 ​​rotatably connected to the inner wall of the cavity 53.

[0036] In use, the precision part to be processed is fixed using the vacuum suction cup body 2. The distance of the precision part is adjusted according to the required processing position. The connecting arm 55 is flipped, causing the rotating shaft 54 ​​to rotate and simultaneously disengaging the limiting block 57 from the limiting groove 56. At this time, the slider 52 disengages from the limiting position, pushing the slider 52. The slider 52 moves inside the slide rail 51, causing the moving inner rod 42 to move inside the fixed rod 41. The moving inner rod 42 moves the vacuum suction cup body 2, thereby adjusting the position of the precision part. When the appropriate position is reached, the connecting arm 55 is reset, and the limiting block 57 is reinserted into the limiting groove 56. When it is necessary to adjust the angle of precision parts during processing, pull the handle 411. The handle 411 drives the limit block 410 to move downward. As the limit block 410 moves downward, it releases the restriction on the first gear 43. At the same time, the limit block 410 drives the movable block 49 to move inside the movable groove 47. The movable block 49 compresses the spring 48. Rotate the handle 44. The handle 44 drives the first gear 43 to rotate. The rotation of the first gear 43 drives the second gear 45 to rotate. The rotation of the second gear 45 can drive the rotating rod 46 to rotate. The rotation of the rotating rod 46 adjusts the angle of the vacuum suction cup body 2, which makes it easier for the staff to process the parts and improves work efficiency.
