Abstract
Description
Technical Field
[0001] This utility model relates to the field of thin-walled part processing technology, specifically a dynamic compensation processing device for precision cutting of weakly rigid thin-walled parts. Background Technology
[0002] The dynamic compensation machining device for precision cutting of weakly rigid thin-walled parts is a device used to solve problems such as deformation due to stress, heat and vibration during precision cutting of weakly rigid thin-walled parts, thereby improving machining accuracy and quality.
[0003] In the prior art, such as the thin-walled casting processing device disclosed in CN207873692U, the device provides auxiliary support for the fixing point of the thin-walled casting through the support block, so as to prevent the thin-walled fixing fixture from being deformed due to excessive pressure, which would lead to the scrapping of the thin-walled casting.
[0004] The aforementioned device fixes the upper and side parts of the workpiece using a clamp. During the workpiece machining process, the internal shape of the workpiece changes, leading to the release of internal stress. The clamping mechanism of this device cannot alleviate the stress release by changing the clamping state, which can cause workpiece deformation. Furthermore, the clamping mechanism requires clamping and fixing the upper and side parts of the workpiece in stages, which increases the complexity of the workpiece clamping process and the probability of uneven force on the workpiece. Therefore, we propose a dynamic compensation machining device for precision cutting of weakly rigid thin-walled parts. Utility Model Content

A slider is provided at the edge of the lifting plate, and the slider is slidably connected to the side of the movable plate near the lifting plate. A clamp is slidably connected to the upper part of the movable plate. A driving member for driving the clamp to slide is provided inside the clamp. A guide member for guiding the movable plate to slide is provided inside the base.

[0010] Preferably, the limiting member includes two evenly distributed limiting blocks disposed on the upper part of the movable plate, and the lower part of the clamp has two evenly distributed limiting grooves, and the limiting blocks slide inside the limiting grooves.
[0011] Preferably, the lower part of the clamp is provided with an anti-slip pad, the lower part of the lifting plate is provided with an electric push rod, the interior of the base is provided with an electric push rod, and the upper end of the electric push rod is located at the lower part of the lifting plate.
[0012] Preferably, an electric push rod 2 is provided in the upper part of the interior of the movable plate, and both the push plate and the slide are inclinedly arranged inside the clamp, with their inclination angle mirror symmetrical to the lower angle of the clamp, and the upper end of the electric push rod 2 is located in the lower part of the push plate.
[0013] This utility model has at least the following beneficial effects:
[0014] 1. During the workpiece processing, the electric actuator is activated to pull the lifting plate and slider downwards. The lifting plate pushes the moving plate to slide in a scattering manner. The moving plate pulls the workpiece to extend in all directions. The lifting plate and suction cup pull the bottom of the workpiece downwards. By providing extension of the workpiece in all directions, the internal stress of the workpiece can be released, preventing deformation of the workpiece during processing.
[0015] 2. Rotate the screw to push the push plate downward. When the push plate pushes the fixture downward, it moves towards the workpiece. When the fixture presses against the surface of the workpiece, the workpiece is fixed. By clamping and fixing the workpiece in multiple directions at the same time, the pressure on each surface of the workpiece can be kept consistent, which can reduce the probability of deformation caused by uneven stress inside the workpiece.

[0028] The guide block 31 keeps the movable plate 22 horizontal when it slides, and the guide groove 32 provides sliding support for the guide block 31.
[0029] Furthermore, the driving component 5 includes a screw 51 rotatably connected to the upper part of the moving plate 22, a push plate 52 threadedly connected to the middle part of the screw 51, a slide groove 53 is provided inside the clamp 24, the push plate 52 slides inside the slide groove 53, and a limiting component 6 for stabilizing the sliding of the clamp 24 is provided on the upper part of the moving plate 22.
[0030] The screw 51 is used to push the push plate 52 to move. The push plate 52 can push the clamp 24 to move when it moves downward, and allows the push plate 52 to slide inside the slide groove 53.
[0031] Furthermore, the limiting member 6 includes two evenly distributed limiting blocks 61 disposed on the upper part of the moving plate 22, and two evenly distributed limiting grooves 62 are provided on the lower part of the clamp 24, and the limiting blocks 61 slide inside the limiting grooves 62.

[0037] The electric actuator 54 can push the push plate 52 to move. By tilting the push plate 52 and the slide 53, the push plate 52 can increase the horizontal pushing force when pushing the slide 53 to move, and reduce the pressure perpendicular to the surface of the slide 53, thereby reducing the friction between the push plate 52 and the slide 53. This makes the push plate 52 slide more smoothly and accurately.
