[0017] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, apparently, the described embodiment is only a part of the embodiment of the utility model, and is not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of protection of the utility model.
[0018] Referring to Figs. 1 to 3 The utility model provides an embodiment: a elastic chuck, including main body 1, for the core support structure of whole elastic chuck, the inside space area fixed connection of main body 1 has the elastic chuck adjusting assembly for fixed clamping, when using, operating personnel can pass specific operation mode, such as rotation, press etc., drive the relative motion of the subcomponent in adjusting assembly, to change the opening and closing degree of chuck 2, this adjusting mode can be adjusted according to the size and shape of the clamped object, so that the elastic chuck can adapt to different specifications of object, has good versatility;
[0019] Adjusting assembly outside left and right sides are provided with axial slot 3, for operating personnel provide an operation channel, it is convenient to manually adjust adjusting assembly, by the tool is inserted into axial slot 3, can drive the motion of the subcomponent in adjusting assembly, to realize the adjustment of chuck 2 opening and closing degree, in addition, axial slot 3 can also be used as observation window, let operating personnel can directly observe the motion in adjusting assembly inside, it is convenient to carry out accurate operation and adjustment;
[0020] The left and right sides of the outside of main body 1 are provided with expansion grooves 4, when the adjusting assembly drives the chuck 2 to expand outward, the chuck 2 will gradually move outward under the guidance of the expansion groove 4, so that the opening of the elastic chuck becomes larger, the existence of the expansion groove 4 can avoid the chuck 2 from receiving excessive resistance during expansion, ensuring that the chuck 2 can be smoothly expanded to the required position, thereby realizing the clamping of objects of different sizes.
[0021] One side of the outside of main body 1 is provided with an origin hole 5 for determining the initial position of the chuck 2, during the use of the elastic chuck, when accurate positioning and adjustment of the chuck 2 is required, the origin hole 5 can be used as a reference datum to ensure that the chuck 2 can accurately return to the initial position or be adjusted to the required position. A locking hole 6 is provided on one side of the outside of main body 1, which is used to lock the chuck 2 after it is adjusted to the appropriate position, preventing accidental movement or loosening of the chuck 2 during use. When the object needs to be clamped, the chuck 2 can be fixed at the current position by inserting a locking pin or other locking component into the locking hole 6, ensuring the stability and reliability of the clamping.
[0022] The bottom side of the axial groove 3 is fixedly connected with a connecting part 7, which connects the axial groove 3 and the clamping sleeve 8 together so that they can work cooperatively. When the adjusting assembly drives the collet 2 to move, the force is transmitted to the connecting part 7 through the axial groove 3, and then to the clamping sleeve 8, so as to drive the collet 2 to move correspondingly. The existence of the connecting part 7 ensures the transmission efficiency and accuracy of the force, so that the whole elastic collet can work normally. The bottom side of the connecting part 7 is fixedly connected with the clamping sleeve 8, which guides and supports the movement of the collet 2. When the collet 2 expands or shrinks under the drive of the adjusting assembly, the clamping sleeve 8 can provide a stable guide track for the collet 2, so that the collet 2 can move along the predetermined direction. At the same time, the clamping sleeve 8 can also bear the lateral force generated during the movement of the collet 2, so as to prevent the collet 2 from deviating or shaking, and ensure the accuracy and stability of clamping.
[0023] The adjusting assembly includes the collet 2. When the adjusting assembly drives the collet 2 to move, the collet 2 expands or shrinks according to the force of the adjusting assembly. When clamping an object, the collet 2 automatically adjusts the opening degree under the pressure of the object, so that the object can be clamped firmly. The surface of the collet 2 is usually hardened or coated to improve its wear resistance and friction, so as to prevent damage to the object during clamping. The collet 2 is fixedly connected to the inside of the main body 1, and the axial groove 3 is fixedly connected to the inside of the collet 2.
[0024] Working principle: When using the elastic collet, the operator can drive the elastic collet adjusting assembly inside the main body 1 by rotating, pressing or other specific operation methods to fix the clamping. The tool is inserted into the axial groove 3 on the left and right sides outside the adjusting assembly, which can drive the sub-components in the adjusting assembly to move, so as to change the opening degree of the collet 2. When the adjusting assembly drives the collet 2 to expand outward, the collet 2 gradually moves outward under the guidance of the expansion groove 4 on the left and right sides outside the main body 1, so that the opening of the elastic collet becomes larger. The origin hole 5 on one side outside the main body 1 can be used to determine the initial position of the collet 2. When it is necessary to accurately position and adjust the collet 2, the origin hole 5 is used as a reference datum. After the collet 2 is adjusted to the appropriate position, the locking pin is inserted into the locking hole 6 on one side outside the main body 1 to lock the collet 2. When the adjusting assembly drives the collet 2 to move, the force is transmitted to the connecting part 7 through the axial groove 3, and then to the clamping sleeve 8, so as to drive the collet 2 to move correspondingly. The collet 2 expands or shrinks under the drive of the adjusting assembly. When clamping an object, the collet 2 automatically adjusts the opening degree under the pressure of the object, so as to firmly clamp the object.
[0025] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
