[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0030] like Figure 1-7 As shown, the utility model provides a positioning tool for the inner panel of the windshield of a protective off-road vehicle, comprising a positioning plate 11, an inner panel positioning pin group 12 vertically arranged at a corresponding position on the inner side of the positioning plate 11, and an outer panel positioning pin group 13 vertically arranged at a corresponding position on the outer side of the positioning plate 11. The inner panel positioning pin group 12 is adapted to the inner positioning hole group 21 on the inner panel 2 of the windshield. It passes through the positioning plate 11 and is inserted into the inner positioning hole group 21 to position the inner panel 2 of the windshield, and the inner panel 2 of the windshield is connected to the positioning plate 11 as a whole through its own strong magnetism. The outer panel positioning pin group 13 is adapted to the outer positioning hole group 3 on the outer panel 3 of the windshield. It is inserted into the outer positioning hole group 31 to complete the positioning of the positioning plate 11, and the outer panel 3 of the windshield is connected to the positioning plate 11 as a whole through its own strong magnetism. The positioning tool of the present invention accurately positions and fixes the front windshield inner panel 2 on the positioning plate 11 through the cooperation of the inner panel positioning pin group 12 and the positioning hole group 21, and accurately positions and fixes the positioning plate 11 on the front windshield outer panel 3 through the cooperation of the positioning pin group 13 and the outer positioning hole group 31, thereby completing the accurate positioning of the front windshield inner panel 2 and carrying out the next welding operation. The positioning tool 1 is simple to operate, can quickly complete the positioning and fixing operation, is easy to disassemble, and can effectively ensure the consistency of the front windshield inner panel 2 after welding.

[0031] like Figure 1-3 As shown, in the embodiment of the present invention, the positioning tool 1 includes a positioning plate 11 , an inner plate positioning pin group 12 and an outer plate positioning pin group 13 .

[0032] The positioning plate 11 is a strip-shaped plate structure. Preferably, in order to reduce the overall weight of the plate body, a plurality of weight-reducing holes 15 are opened on the positioning plate 11.

[0033] The inner plate positioning pin group 12 includes a first inner positioning pin 121, a second inner positioning pin 122, a third inner positioning pin 123, a fourth inner positioning pin 124, and a fifth inner positioning pin 125. The positions of these five positioning pins on the positioning plate 11 correspond to the inner positioning hole group 21 on the front windshield inner plate 2. The first inner positioning pin 121 has the same structure as the second inner positioning pin 122, the third inner positioning pin 123, the fourth inner positioning pin 124, and the fifth inner positioning pin 125, and includes an inner pin rod 1211 and a positioning needle rod 1212 fixed to the front end of the inner pin rod 1211; the inner pin rod 1211 is embedded in the observation limit hole 18; the observation limit hole 18 is provided on the positioning plate 11, and its inner diameter is the same as the outer diameter of the inner pin rod 1211. By observing the limit hole 18, the position of the positioning hole group 21 on the front windshield inner plate 2 can be observed, and the positioning work can be completed more quickly. To prevent the inner pin rod 1211 from deflecting the front windshield inner panel 2, thereby reducing the distance between the front windshield inner panel 2 and the positioning plate 11 and causing inaccurate positioning, an annular step portion is provided in the observation limit hole 18, whose inner diameter is smaller than the inner pin rod 1211. This limits the insertion depth of the inner pin rod 1211, thereby preventing the inner positioning pin 121 from pushing the front windshield inner panel 2 away. Preferably, to prevent the first inner positioning pin 121 from falling during operation, a rope chain 17 is connected to the rear end of the first inner positioning pin 121, and the other end of the rope chain 17 is connected to the tie column 16 provided on the positioning plate 11.

[0034] The outer panel positioning pin group 13 includes a first outer positioning pin 131 and a second outer positioning pin 132, both of which are located on the positioning plate 11 and correspond to the outer positioning hole group 31 on the front windshield outer panel 3. The first outer positioning pin 131 and the second outer positioning pin 132 have the same structure, including an outer pin rod 1311 and an outer step rod 1312 provided at the front end of the outer pin rod 1311, and the central axes of the two coincide with each other; furthermore, the outer diameter of the outer step rod 1312 is adapted to the inner diameter of the outer positioning hole group 31, and its outer diameter is smaller than the outer diameter of the outer pin rod 1311. By inserting the outer step rod 1312 into the outer positioning hole group 31 for magnetic fixation, and making the front end of the outer pin rod 1311 block and limit the front windshield outer panel 3, the distance between the positioning plate and the front windshield outer panel 3 can be limited, achieving the precise positioning of the spacing between the front windshield inner panel 2 and the front windshield outer panel 3.

[0035] Furthermore, in order to facilitate holding the positioning tool 1, a handle group 14 is provided on the inner side of the positioning plate 11. The handle group 14 includes a first handle 141 and a second handle 142. By holding the first handle 141 and the second handle 142, the operator can easily separate the front windshield inner panel 2 and the front windshield outer panel 3 that are magnetically fixed to the positioning plate 11.

[0036] like Figure 5As shown, in the embodiment of the present invention, a positioning hole group 21 is provided on the front windshield inner panel 2 for precise positioning, and the positioning hole group 21 includes a first inner positioning hole 211, a second inner positioning hole 212, a third inner positioning hole 213, a fourth inner positioning hole 214 and a fifth positioning hole 215. The five positioning holes correspond to the first inner positioning pin 121, the second inner positioning pin 122, the third inner positioning pin 123, the fourth inner positioning pin 124 and the fifth inner positioning pin 125 respectively; wherein, the first inner positioning hole 211 corresponds to the first inner positioning pin 121, and its inner diameter is adapted to the rod diameter of the positioning needle rod 1212. The positioning needle rod 1212 passes through the observation limit hole 18 and is inserted into the first inner positioning hole 211 to complete the positioning work.

[0037] like Figure 7 As shown, the outer positioning hole group 31 includes a first outer positioning hole 311 and a second outer positioning hole 312; the first outer positioning hole 311 corresponds to the first outer positioning pin 131, and the second outer positioning hole 312 corresponds to the second outer positioning pin 132, wherein the aperture of the first outer positioning hole 311 is adapted to the outer diameter of the outer step rod 1312, and the outer step rod 1312 is inserted into the first outer positioning hole 311 for positioning. Since the aperture of the first outer positioning hole 311 is smaller than the diameter of the outer pin rod 1311, the front end of the outer pin rod 1311 is blocked and limited, thereby quickly and accurately positioning the distance between the front windshield outer panel 3 and the positioning tooling 1.

[0038] In the embodiment of the present invention, the inner panel positioning pin group 12 and the outer panel positioning pin group 13 are made of strong magnetic material and have excellent magnetic properties, and can firmly adsorb and fix the front windshield inner panel 2 and the front windshield outer panel 3.

[0039] like Figure 6-7As shown, in the embodiment of the present invention, when the positioning tool 1 is performing the positioning and fixing operation of the front windshield inner panel 2, the front windshield inner panel 2 is fitted with the outer side of the positioning plate 11, and the inner positioning hole group 21 is aligned with the observation limit hole 18 for preliminary positioning; the first inner positioning pin 121 is inserted into the observation limit hole 18 until the inner pin rod 1211 conflicts with the annular step portion provided in the observation limit hole 18. At this time, the positioning needle rod 1212 at the front end of the first inner positioning pin 121 passes through the observation limit hole 18 and is inserted into the first inner positioning hole 211 for magnetic fixation, thereby positioning the front windshield inner panel 2; the second inner positioning pin 122, the third inner positioning pin 123, the fourth inner positioning pin 124 and the fifth inner positioning pin 125 are inserted into the second inner positioning hole 212, the third inner positioning hole 213, the fourth inner positioning hole 214 and the fifth positioning hole 215 in sequence for magnetic fixation, so that the positioning tool 1 is aligned with the front windshield inner panel 2 The window inner panel 2 is connected as one, and the front windshield inner panel 2 is accurately positioned on the positioning tool 1; the first outer positioning pin 131 and the second outer positioning pin 132 that pass through the through holes on the front windshield inner panel 2 are aligned with the first outer positioning hole 311 and the second outer positioning hole 312 respectively, and are inserted into the first outer positioning hole 311 and the second outer positioning hole 312 for magnetic fixation until the front end of the outer pin rod 1311 is blocked and limited by the outer positioning hole group 31, so as to quickly and accurately locate the distance between the front windshield outer panel 3 and the positioning tool 1, and then complete the accurate positioning and fixing of the front windshield inner panel 2, and the next welding operation can be carried out; the welding operation is carried out on all sides of the front windshield inner panel 2 according to the process requirements. After completion, the operator holds the first handle 141 and the second handle 142, and can quickly pull out the positioning tool 1 from the front windshield inner panel 2 and the front windshield outer panel 3 to carry out the next group of positioning and fixing work.

[0040] The positioning tooling of the present invention can perform precise positioning. By adapting the inner plate positioning pin group 12 to the positioning hole group 21 on the front windshield inner plate 2, the front windshield inner plate 2 is precisely positioned and fixed on the positioning plate 11. At the same time, the outer plate positioning pin group 13 is adapted to the outer positioning hole group 31 on the front windshield outer plate 3, so that the positioning plate 11 is precisely positioned and fixed on the front windshield outer plate 3, ensuring the consistency of the welding operation.

[0041] The positioning tool of the present invention has a simple and easy-to-operate positioning and fixing process. The inner panel positioning pin group 12 has a strong magnetism, thereby connecting the windshield inner panel 2 and the positioning plate 1 as a whole. The outer panel positioning pin group 13 is fixed by magnetic attraction, which simplifies the positioning and fixing operation of the positioning plate 11 and the windshield outer panel 3, allowing the operator to quickly complete the positioning and fixing, thereby improving work efficiency.

[0042] The positioning tool of the present invention is easy to disassemble. After the operation is completed, the operator can easily and quickly pull out the positioning tool 1 from the front windshield inner panel 2 and the front windshield outer panel 3 by holding the handle group 14 on the positioning plate 11, which is convenient for the positioning and fixing work of the next group, thereby improving the flexibility and reusability of the operation.
