[0029] The following will further elaborate on the quick-switching positioning fixture structure of this utility model with reference to specific embodiments, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the technical solution of this utility model.

[0030] Example 1

[0031] like Figure 1-7 As shown, the quick-change positioning fixture structure of this embodiment includes a sloping base 101, a positioning connecting plate 102, a sliding guide structure 103, a sliding limiting structure 104, a rolling support structure 105, and a telescopic positioning structure 106. The sloping base 101 is fixed to the ground with expansion bolts and forms a sloping structure at a certain angle to the ground, facilitating rapid up-and-down movement and installation of the fixture. The positioning connecting plate 102 includes a connecting plate body and a positioning mounting seat and a positioning mounting point disposed on the connecting plate body. The connecting plate body is parallel to the sloping base 101 and is fastened to the sloping base with bolts. The sliding guide structure 103 is disposed in the middle of the positioning connecting plate 102 and is fastened to the positioning mounting point with bolts. The sliding guide structure 103 provides horizontal guidance and coarse limiting for the fixture's placement. The sliding guide structure 103 is a symmetrical structure and forms a guide path. The sliding limiting structure 104 is located at the rear of the sliding guide structure 103 and is fastened to the positioning mounting point by bolts. The sliding limiting structure 104 has an L-shaped structure and provides a limiting function in the forward direction for the fixture to be positioned. The rolling support structure 105 is bolted to the positioning mounting seat. There are four rolling support structures 105, which are fixedly set on the positioning mounting seats at the four corners of the positioning connecting plate 102. The rolling support structure 105 includes a support base and ball bearings set on the support base. The telescopic positioning structure 106 is located on the positioning mounting seat. There are two telescopic positioning structures 106, which are fixedly set on the positioning mounting seats at the two lower corners of the positioning connecting plate 102. The telescopic positioning structure 106 includes a cylinder and a positioning pin set on the cylinder. The height of the positioning pin can be adjusted by the action of the cylinder, thereby preventing the fixture from interfering with the upper and lower slope base 101 and ensuring the positioning accuracy of the fixture. The cylinder is bolted to the positioning mounting seat. Figure 8-9 A schematic diagram illustrating an application scenario of the quick-switching positioning fixture structure of this embodiment is shown.

[0032] The quick-change positioning fixture structure in this embodiment uses expansion bolts to connect to the ground. The inclined base 101 and rolling support structure 105 facilitate the convenient transportation of the upper and lower bases of the fixture, enabling the fixture switching process without the need for handling equipment. The sliding guide structure 103 and sliding limit structure 104 achieve coarse positioning of the fixture and the base, and the telescopic positioning structure 106 further achieves precise positioning of the fixture, eliminating the need for manual bolt installation. This significantly improves the efficiency of fixture switching time, enables flexible production of sub-assembly fixtures, and enhances the overall efficiency of the equipment.

[0033] For those skilled in the art, the specific embodiments are merely exemplary descriptions of the present invention. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention are within the protection scope of the present invention.
