Description

Technical Field

[0001] The utility model belongs to the technical field of lathe processing, and specifically relates to a clamping device for controlling the processing deformation of thin-walled parts, and more particularly to the process of rough and fine processing of thin-walled parts on a lathe. Background Art

[0002] In the actual processing process, there are many cases of processing thin-walled parts on lathes. The traditional processing method is to use clamping jaws. On the one hand, this clamping method is easy to cause deformation of thin-walled parts. At the same time, secondary clamping is required when processing inner holes and outer circles. This method has a big problem that it causes large deformation of thin-walled parts on lathes, low efficiency, and easy to cause parts to be scrapped, resulting in a significant increase in the processing cost of parts. Utility Model Content

[0003] The utility model provides a clamping device for controlling machining deformation of thin-walled parts, which solves the above problem.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a clamping device for controlling the processing deformation of thin-walled parts, characterized in that it includes an electromagnetic suction cup, a magnetic block, a cushion block and a slider; the magnetic block is provided with a T-shaped track along the axial direction, and a plurality of magnetic blocks are evenly fixed on the electromagnetic suction cup along the circumference, and a slider is slidably connected in the T-shaped track of each magnetic block, and a cushion block is fixed on the slider; the thin-walled parts are electromagnetically sucked on the cushion block, and the parts are fixed on the cushion block in the axial direction.

[0005] Beneficial effects: The utility model can replace the processing device for clamping thin-walled parts on a lathe with a traditional chuck, realize the turning processing of thin-walled parts on the lathe, and reduce the deformation of the parts.

[0006] If you need to process inner holes and outer circles, there is no need for secondary clamping. After the electromagnetic chuck sucks the parts, you can directly adjust the position of the slider and the pressure plate to achieve direct processing of the inner holes and outer circles, and turn over and directly process the remaining end faces. At the same time, it can control the processing deformation of thin-walled parts, improve the processing quality and processing efficiency of thin-walled parts, reduce the scrap rate of parts, and save processing costs. This clamping device provides an effective reference model for lathe processing of similar thin-walled parts, which can be achieved by simply changing the position of the magnetic block and the stroke of the slider.

[0012] In order to make the purpose, content and advantages of the utility model clearer, the specific implementation methods of the utility model are further described in detail below.

[0013] The utility model provides a clamping device for controlling the processing deformation of thin-walled parts, comprising an electromagnetic chuck, a long magnetic conductive block 1, a short magnetic conductive block 2, a cushion block 3 and a slide block 4;

[0014] The long magnetic conductive blocks 1 and the short magnetic conductive blocks 2 are both provided with T-shaped tracks along the axial direction, a plurality of long magnetic conductive blocks 1 are evenly distributed and fixed on the electromagnetic chuck along the circumference, and a plurality of short magnetic conductive blocks 2 are alternately arranged between the long magnetic conductive blocks;

[0015] Slide blocks are slidably connected in the T-shaped tracks of the long magnetic conductive block 1 and the short magnetic conductive block 2, and cushion blocks 3 are fixed on the slide blocks; the long magnetic conductive block 1 and the short magnetic conductive block 2 can be used to clamp workpieces of different sizes.

[0016] Thin-walled parts are attached to the pads by electromagnetic suction, which fixes the parts in the axial direction.

[0017] Equipped with corresponding pressing plates, bolts and nuts, the thin-walled parts can be fixed on the pads using the pressing plates and then the turning process can be carried out.

[0018] Determine the size of the magnetic block and spacer according to the outer circle, inner hole and wall thickness of the part.

[0019] The magnetic blocks with tracks that are designed to have different sizes and reasonable structures must meet the corresponding accuracy requirements of the structure and be fixed to the electromagnetic chuck with hexagon socket bolts when in use.

[0020] According to the size of the parts, the position of the pad is adjusted by the slider, and the thin-walled parts are electromagnetically sucked onto the pad.

[0021] This device can provide an effective reference model for similar thin-walled zero lathe processing, which can be realized by simply changing the position of the magnetic block and the stroke of the slide. The part can be a gear structure.

[0022] The biggest advantage of this device is that it can reduce the clamping and processing deformation of thin-walled parts, and there is no need to clamp the workpiece again, which greatly improves the processing accuracy and efficiency; the device has low manufacturing cost and is easy to operate, which greatly improves the processing efficiency and reduces the processing cost of thin-walled parts.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
