Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically specified.

[0034] Reference Figures 1-8 As shown, this embodiment provides a specific implementation method for a positioning structure of an automobile part with a fine-tuning function, including a plurality of positioning holes 10 of the automobile part, a first positioning tool 20, and a second positioning tool 30. The first positioning tool 20 and the second positioning tool 30 are respectively movably matched with the positioning holes 10 at the horizontal ends of the automobile part;

[0035] During the specific implementation of the present invention, the first positioning tool 20 is used to determine the positioning hole at one end of the automobile accessory, and then the second positioning tool 30 is used to elastically adjust the second positioning rod 305, so that the first positioning rod 203 and the second positioning rod 305 can pass through the positioning hole 10 on the automobile accessory. This is not limited by the manufacturing material of the automobile accessory, and the positioning holes on automobile accessories made of steel or aluminum materials may also be used if there are deviations.

[0036] The second positioning fixture 30 includes a second platform 302 ; a slide rail 303 mounted on the second platform 302 and capable of elastically driving the second positioning rod 305 to slide; and a second positioning rod 305 fixed on the slide rail 303 .

[0037] Furthermore, the slide rail 303 includes a slider 331, two rails 332, a spring 333, a first bracket 334, a slide rod 335, and a fixing platform 336. The rails 332 are parallel to each other and locked to the top surface of the second platform 302. Each rail 332 is equipped with a slider 331 that slides horizontally. The top ends of the two sliders 331 to 332 are connected and fixed by a fixing platform 336.

[0038] A first bracket 334 is fixed to the tail end of the second platform 302 , and a sliding rod 335 parallel to the track 332 is horizontally fixed to the top of the first bracket 334 ;

[0039] The slide bar 335 is slidably matched with the fixed platform 336 , and the spring 333 is sleeved on the slide bar 335 between the fixed platform 336 and the first bracket 334 , so as to enable the fixed platform 336 to slide horizontally left and right on the slide bar 335 .

[0040] The track 332 and the slider 331 cooperate with each other to limit the horizontal movement direction of the second positioning rod 305. When the spring 333 is unable to pass through the positioning hole of the automobile accessory after the second positioning rod 305 touches the positioning hole of the automobile accessory, the automobile accessory is gradually pressed down, and the second positioning rod 305 is subjected to pressure and deflected. The spring 333 is compressed or stretched, so that the second positioning rod 305 completely passes through the positioning hole 10 to achieve fixation. After use, the second positioning rod 305 is disengaged from the positioning hole 10, and the spring 333 is reset, driving the second positioning rod 305 to return to its original position.

[0041] Furthermore, the second positioning tool 30 includes a second cylinder 301; the output end of the second cylinder 301 is fixed to the bottom surface of the second platform 302, driving the second platform 302 to rise or fall, allowing the second positioning rod 305 to move upward and completely pass through the positioning hole 10 to achieve fixation; or the second positioning rod 305 moves downward and disengages from the positioning hole 10.

[0042] As a further improvement, the slide rail 303 further includes a second bracket 337 , one end of the second bracket 337 is screwed to the head end of the fixing platform 336 , and the other end is screwed to the second positioning rod 305 .

[0043] In one specific embodiment, the second positioning tool 30 further includes a limiting bracket 304, which is arranged on the side of the second platform 302 to limit the horizontal movement and forward and backward movement of the second positioning rod 305, and confine it to a certain spatial range to ensure accurate positioning function.

[0044] Furthermore, the limiting bracket 304 includes a fixing portion 341, a third bracket 342, and a notch 343. The third bracket 342 includes a horizontal portion and a vertical portion. The bottom end of the vertical portion of the third bracket 342 is fixed to the processing equipment through the fixing portion 341.

[0045] A notch 343 is formed at the head end of the horizontal portion of the third bracket 342 , and the second positioning rod 305 moves in the notch 343 .

[0046] In one specific embodiment, the notch 343 is U-shaped, which restricts the second positioning rod 305 from moving in the U-shaped notch 343. The open notch is convenient for observation and easy to adjust.

[0047] Among them, the first positioning tool 20 includes a first cylinder 201, a first platform 202, and a first positioning rod 203. The bottom end of the first platform 203 is connected to the output end of the first cylinder 201. The first positioning rod 203 is fixed on the first platform 202. The top end of the first positioning rod 203 cooperates with the positioning hole 10.

[0048] The first positioning tool 20 of the present invention drives the first platform 202 to rise or fall through the operation of the first cylinder 201, thereby driving the first positioning rod 203 to move upward and completely pass through the positioning hole 10 to achieve fixation; or the first positioning rod 203 moves downward and leaves the positioning hole 10.

[0049] In one specific embodiment, the width of the top end of the first positioning rod 203 and the second positioning rod 305 is smaller than the column body of the first positioning rod 203 and the second positioning rod 305, so that the top end of the first positioning rod 203 and the second positioning rod 305 can partially penetrate the positioning hole 10, providing a basis for elastic adjustment.

[0050] In one specific embodiment, the shapes of the top ends of the first positioning rod 203 and the second positioning rod 305 include but are not limited to diamond or cone shapes, as long as they can pass through the positioning hole 10.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
