[0005] Further, a threaded hole is formed in the chuck body, a screw is arranged on the clamping block, and the threaded end of the screw is screwed with the threaded hole after penetrating through the clamping block.

[0006] Further, a limiting groove extending inwardly is formed in the front surface of the chuck body, and a limiting part corresponding to the limiting groove is formed in the clamping block.

[0007] Further, a receiving hole extending inwardly is formed in the front surface of the clamping block, and the receiving hole is adapted to the head of the screw.

[0008] Further, a hexagonal groove extending inwardly is formed in the head of the screw.

[0009] The utility model discloses a quick replacement's number of car chuck, which can process the clamping block first for high-precision parts to ensure the clamping precision, and the new clamping block can be replaced when the clamping block cannot ensure the precision after being used for many times, so that the processing precision of the part is ensured, and the whole chuck body does not need to be replaced, thereby reducing the processing cost.

[0014] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0015] In the present application, unless otherwise explicitly specified and limited, the terms "connection", "fixing" should be understood broadly, for example, can be fixed connection, can also be detachable connection, or integral; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship of two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0016] In the description of the present application, it should be understood that the orientation or position relationship indicated by the terms "vertical", "horizontal", "horizontal", "top", "bottom", "upper", "lower", "inner" and "outer" is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the utility model.

[0017] In addition, the terms "first", "second" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. In the description of the utility model, the meaning of "multiple" is two or more, unless otherwise explicitly specified and limited.

[0018] As Figs. 1-3 As shown in the utility model provides a kind of quick replacement's number of vehicle chuck, including three chuck assemblies 10, three chuck assemblies 10 are sequentially arranged along ring direction equidistantly, above-mentioned content is prior art, specific structure is not repeated here. Specifically, in the utility model chuck assembly 10 includes chuck body 11, the inner end of chuck body 11 is provided with clamping block 12, clamping block 12 is detachably connected with chuck body 11.

[0019] The utility model discloses a chuck body 11 is provided with the clamping block 12, and the clamping block 12 is connected with the chuck body 11 through the screw 13, and the clamping block 12 is used for clamping the part to be processed.
