[0002] Machining refers to the process of changing the size or performance of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure processing. The process is the basic unit of the machining process. The so-called process refers to the part of the process that workers continuously complete on the same workpiece (or several workpieces at the same time) on the machine tool or at the workplace. The main characteristics of a process are that the processing object, equipment and operator are not changed, and the content of the process is completed continuously.
[0003] The machines needed for processing include digital milling machines, digital profile grinders, digital lathes, EDM machines, universal grinders, machining centers, laser welding, medium wire, fast wire, slow wire, external cylindrical grinder, internal cylindrical grinder, precision lathes, etc. However, no matter what kind of machine is used to process the workpiece, the workpiece raw material must be clamped and fixed with a fixture before the processing to ensure the stability of the workpiece during processing and the accuracy of the workpiece after the processing is completed.
[0004] At present, ordinary chucks or pull-back chucks are mainly used for clamping and fixing thin-walled parts (similar to round tubes, discs, flanges, covers, etc.), while self-centering chucks are used to fix irregular blank surfaces. However, due to the overall thinness of thin-walled parts, the force applied when the chuck is clamped and fixed cannot be accurately controlled, which easily leads to clamping deformation and springback after processing, affecting the processing accuracy of the product.

DETAILED DESCRIPTION
[0024] Embodiment 1:
[0025] A parallel displacement jacket for machining thin-walled parts, such as Figure 1-Figure 6 As shown, it includes a jacket body 2 and a support ring frame 3 arranged on one side of the jacket body 2, the jacket body 2 includes a jacket shell 202, an inner sleeve 203 is integrally formed on the inner wall of one side of the jacket shell 202, the outer sleeve 203 is sleeve-connected with a control disk 206, a surface of one side of the control disk 206 is processed with a fan-shaped worm gear 204, and the outer part of the fan-shaped worm gear 204 is meshingly connected with a worm 205;
[0026] The worm 205 is mounted inside the jacket housing 202, so that the staff can control the rotation of the worm 205 from the outside of the jacket housing 202 with the help of a tool, thereby driving the fan-shaped worm wheel 204 to rotate outside the inner sleeve 203, and finally driving the control disk 206 to rotate inside the jacket housing 202;
[0027] like Figure 4 and Figure 5 As shown, the surface of the other side of the control plate 206 is processed with a plurality of control inclined grooves 10, and a controlled slide 207 is disposed inside each of the plurality of control inclined grooves 10, and a clamping seat 201 is installed outside one side of the controlled slide 207;
[0028] Among them, a plurality of slide grooves 5 are processed on the surface of one side of the jacket shell 202, and a plurality of control inclined grooves 10 are equally spaced around the center of the control disk 206. A plurality of slide grooves 5 are equally spaced around the center of the jacket shell 202. When the control disk 206 is controlled by the rotating worm 205 to control the fan-shaped worm gear 204 to rotate outside the inner sleeve 203, and thus rotates inside the jacket shell 202, the plurality of controlled slide seats 207 can be synchronously driven by the plurality of control inclined grooves 10 to slide from a position close to the center of the control disk 206 to a position away from the circle of the control disk 206, or driven to slide from a position away from the circle of the control disk 206 to a position of the center of the control disk 206, thereby respectively controlling the plurality of clamping seats 201 to slide inside the plurality of slide grooves 5, and using the plurality of clamping seats 201 to clamp and fix the thin-walled part 4;
[0029] In some examples, in order to prevent the multiple jacket shells 202 from being compressed from the periphery to the center, a large pressure is applied to the thin-walled tube 4, causing the thin-walled tube 4 to be deformed due to excessive local pressure, thereby affecting the processing accuracy. Figure 2 and Figure 5 As shown, an arc plate is formed on the surface of one side of the clamping seat 201, and the arc plates on the clamping seat 201 are arranged in a circle. By extending the center of one side of the thin-walled part 4 into the inner side of the multiple arc plates, the thin-walled part 4 can be clamped toward the center with the help of multiple jacket shells 202, so as to ensure that the thin-walled part 4 is stressed as a whole and avoid the change of the shape caused by excessive local pressure;
[0030] At the same time, by setting the surface of one side of the support ring frame 3 in a profiling form, when the center of one side of the thin-walled member 4 is extended into the inner side of the plurality of arc plates, the edge of one side of the thin-walled member 4 is made to lean against the surface of one side of the support ring frame 3, and the surface of one side of the support ring frame 3 is adapted to the surface of one side of the thin-walled member 4, so as to avoid deformation of the thin-walled member 4 and affect the appearance when processing the surface of the other side of the thin-walled member 4 due to lack of support on the back side and greater force applied on the front side;
[0031] Secondly, one side of the jacket shell 202 is assembled with a mounting rear cover 1, and the other side surface of the jacket shell 202 is assembled with a partition front cover 8. By utilizing the mounting rear cover 1 to encapsulate the fan-shaped worm gear 204 into the interior of the jacket shell 202, the worm 205 can be supported to control the fan-shaped worm gear 204 to rotate outside the inner sleeve 203, and the internal interference fit of the bearing or support with a cylindrical seat on one side of the mounting rear cover 1 can install the mounting rear cover 1 on a fixed support, which can support the thin-walled part 4 clamped and fixed by the jacket body 2 to be processed.
[0032] The utility model discloses a parallel displacement jacket for processing thin-walled parts. By arranging a support ring frame 3 on the outside of one side of the jacket shell 202 on the jacket body 2, the thin-walled part 4 is installed to one side of the jacket body 2 in translation and leans against the surface of the support ring frame 3. When the control worm 205 rotates, the fan-shaped worm wheel 204 is driven to rotate on the outside of the inner sleeve 203, thereby driving the control disk 206 to rotate on the inner side of the jacket shell 202, multiple controlled slide seats 207 can be driven to slide from a circular position away from the control disk 206 to the position of the center of the control disk 206, thereby respectively controlling multiple clamping seats 201 to slide inside multiple slide grooves 5 respectively, realizing the function of gathering from the surroundings to the center, and clamping the thin-walled part 4. At this time, because the worm 205 controls the fan-shaped worm wheel 204 and the outer side of the inner sleeve 203 to be a one-way transmission, the state of multiple clamping seats 201 clamping and fixing the thin-walled part 4 can be maintained;
[0033] At the same time, by setting the area where the clamping seat 201 performs the clamping function in the form of an arc surface, and the arc plate is adapted to the shape of the corresponding thin-walled part 4, when the center of one side of the thin-walled part 4 is extended into the inner side of multiple arc plates, so that the center of one side of the thin-walled part 4 is clamped and fixed by multiple clamping seats 201, the surface of the arc plate is in contact with the surface of the center of one side of the thin-walled part 4, which can avoid the pressure applied to the thin-walled part 4 acting on the local area, causing local deformation of the thin-walled part 4 and affecting the processing accuracy.
[0034] Embodiment 2:
[0035] On the basis of Example 1, Figure 1-Figure 4As shown, this embodiment is an auxiliary structure of the support ring frame 3, a first support ring 6 is arranged on the inner side of the support ring frame 3, a second support ring 7 is arranged on the inner side of the first support ring 6, and a plurality of fixing strip seats 9 are integrally formed on the surface of one side of the second support ring 7;
[0036] Among them, the surface around the first support ring 6 is adapted to be connected to the inner wall of the support ring frame 3, and a plurality of fixing strip seats 9 are equally spaced around the center of the second support ring 7. After the fixing strip seats 9 are assembled and fixed to the surface of one side of the jacket shell 202 by bolts, the support ring frame 3 is sleeved on the outside of the jacket shell 202 and assembled and fixed therewith, so that the first support ring 6 can be compressed and fixed between the second support ring 7 and the support ring frame 3, which is simple and convenient.
[0037] At the same time, by locating the fixing bar seat 9 between two adjacent clamping seats 201, when the multiple clamping seats 201 are controlled to move back and forth between the positions of the clamping seats 201 close to the center of the circle and away from the center of the circle, it can be avoided that the fixing bar seat 9 interferes with the movement of the clamping seats 201;
[0038] In addition, when the center of one side of the thin-walled part 4 is extended into the inner side of multiple arc plates, the center of one side of the thin-walled part 4 is clamped and fixed by multiple clamping seats 201, and it is made to lean against the surface of the support ring frame 3, the first support ring 6 and the second support ring 7 can be used to support the surface of one side of the thin-walled part 4 to assist the support ring frame 3 in performing the supporting function, thereby avoiding the situation where the clamped part and the edge part of the thin-walled part 4 are too far apart, or the thin-walled part 4 is too thin as a whole, which causes most of its area to be compressed and prone to surface deformation.
[0039] The utility model discloses a parallel displacement chuck for processing thin-walled parts. By arranging a first support ring 6 and a second support ring 7 on the inner side of a support ring frame 3, after the second support ring 7, the support ring frame 3 and the chuck shell 202 are fixed, the first support ring 6 can be squeezed and fixed between the support ring frame 3 and the second support ring 7. When the first support ring 6 and the second support ring 7 cooperate with the support ring frame 3 to perform the supporting function, when a plurality of clamping seats 201 clamp the thin-walled parts 4, the surface of the thin-walled parts 4 can be pressed and not easily deformed, and will not be affected by the overall size and thickness thereof.
[0040] It should be noted that, when in use, the shape of the surface of one side of the support ring frame 3, the part of the clamping seat 201 that performs the clamping function, and the use of the first support ring 6 and the second support ring 7 all need to be adjusted according to the actual shape of the thin-walled part 4. While ensuring that the application itself is overall adapted to the shape of the thin-walled part 4, the one side of the jacket body 2 can be used to close and clamp, so that the pressure area of the thin-walled part 4 is greatly increased, and the support ring frame 3 is supported on one side of the thin-walled part 4 or the first support ring 6, the second support ring 7 and the support ring frame 3 are combined to support one side of the thin-walled part 4, so as to avoid local compression and deformation of the thin-walled part 4 during processing, affecting the processing accuracy, and then, repeated corrections are required, affecting the processing efficiency.
[0041] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
