[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-4 A welding part size inspection fixture includes a fixture base plate 1. Two sets of support legs 12 are fixedly connected to the bottom surface of the fixture base plate 1. The bottom end of each set of support legs 12 is fixedly connected to a support chassis 13. The two sets of support legs 12 and the support chassis 13 form a support structure, which facilitates the support of the inspection fixture.

[0024] The upper surface of the inspection fixture base plate 1 is fixedly connected with a right-angle measuring cross bar 2 and a vertical measuring rod 14, respectively. The outer surface of the vertical measuring rod 14 is fixedly connected to the outer surface of the right-angle measuring cross bar 2. The outer surface of the right-angle measuring cross bar 2 is fixedly inlaid with two horizontal measuring rulers 6. Both side surfaces of the vertical measuring rod 14 are fixedly inlaid with vertical measuring rulers 24. The interior of the right-angle measuring cross bar 2 is slidably connected to two horizontal sliding blocks 3. The two horizontal sliding blocks 3 are each provided with a sliding limit groove 7 on one side where they are close to each other. An extension slide 8 is slidably connected to the interior of each sliding limit groove 7. The extension slide 8 is slid inside the sliding limit groove 7 to extend the horizontal sliding block 3, thereby facilitating the inspection and measurement of large-sized welding parts.

[0025] The two horizontal sliding blocks 3 are fixedly connected to the limit baffle 4 on the side away from each other. The bottom surface of each horizontal sliding block 3 and the bottom surface of each limit baffle 4 are in contact with the upper surface of the inspection fixture base plate 1. The two extended slides 8 are fixedly connected to the side away from each other with a sliding stopper 9. Each sliding stopper 9 is slidably connected to the inside of the sliding limit groove 7. By sliding the sliding stopper 9 inside the sliding limit groove 7, the internal sliding position of the extended slide 8 in the sliding limit groove 7 can be conveniently limited, thereby improving the movement stability of the extended slide 8.

[0026] A horizontal indicator needle 5 is fixedly connected to the upper surface of each limit baffle 4, and a pulling plate 10 is fixedly connected to the side where the two extension slides 8 are close to each other. The bottom surface of each pulling plate 10 is in contact with the upper surface of the inspection tool base plate 1, and a pulling handle 11 is fixedly connected to the side where the two pulling plates 10 are close to each other. By manually holding the pulling handle 11, the pulling plate 10 is used to pull the extension slide 8, thereby facilitating the extension of the extension slide 8.

[0027] A sliding groove 15 is provided on the outer surface of the vertical measuring rod 14, and a fastening groove 21 is provided on the front and back sides of the vertical measuring rod 14. Each fastening groove 21 is connected to the sliding groove 15, and a fastening plate 22 is slidably connected to the interior of each fastening groove 21. Through the fastening groove 21, the fastening plate 22 can slide inside it, thereby facilitating the limiting of the structure inside the sliding groove 15.

[0028] The sliding groove 15 is internally slidably connected to a vertical sliding block 16, the bottom surface of the vertical sliding block 16 is fixedly connected to an upper baffle 18, the upper surface of the upper baffle 18 is fixedly connected to a lifting rod 19, and the top of the lifting rod 19 is fixedly connected to a lifting plate 20. By manually holding the lifting rod 19, the arm can be blocked by the lifting plate 20, thereby facilitating the lifting of the upper baffle 18.

[0029] The vertical indicator needles 17 are fixedly connected to both side surfaces of the vertical sliding block 16, and the interiors of the two fastening plates 22 are commonly threadedly connected with a tightening positioning bolt 23, which is threadedly connected to the interior of the vertical sliding block 16. The end of the tightening positioning bolt 23 away from the vertical measuring rod 14 passes through the two fastening plates 22 and the vertical sliding block 16 in sequence and extends to the back of the vertical measuring rod 14. The tightening positioning bolt 23 is manually twisted to squeeze the fastening plate 22, so that the fastening plate 22 cannot slide inside the fastening slot 21.

[0030] The working principle of the present invention is as follows: when the inspection fixture is needed to inspect and measure the size of a welded part, the fixture is first placed manually at the required position, and the support structure consisting of two sets of support legs 12 and a support base 13 is used to stably install the fixture at the required position, so that the size of the welded part can be stably inspected and measured. Then, the welded part to be inspected is placed manually on the bottom plate 1 of the fixture, and the two side surfaces of the welded part are respectively in contact with the inner side walls of the right-angle measuring crossbar 2;

[0031] By manually moving the horizontal sliding block 3 in the right-angle measuring crossbar 2, the horizontal sliding block 3 can be made to slide on the inspection tool base plate 1, and by manually holding the pulling handle 11, the pulling plate 10 can be used to pull the extension slide plate 8 to slide in the sliding limit groove 7 opened on one side of the horizontal sliding block 3, so as to facilitate the extension of one side of the horizontal sliding block 3 to measure the larger-sized welding parts, until the two horizontal sliding blocks 3 and one side of the pulling plate 10 can contact the two side surfaces of the welding parts. In the process of moving the horizontal sliding block 3, the horizontal indicator needle 5 fixed on the fixed limit baffle 4 on one side of the horizontal sliding block 3 will slide, and since the horizontal indicator needle 5 is arranged on one side of the fixed horizontal measuring ruler 6 on one side of the right-angle measuring crossbar 2, the horizontal size of the welding part can be measured by the horizontal indicator needle 5 corresponding to the size position of the horizontal measuring ruler 6, and since the horizontal measuring ruler 6 is provided with a mark at the position corresponding to the reasonable tolerance size of the welding part, the reasonable tolerance horizontal size of the welding part can be quickly inspected and measured;

[0032] Then, the positioning bolt 23 is manually twisted and tightened to prevent the fastening plate 22 from squeezing the inside of the fastening slot 21, so that the vertical sliding block 16 can slide in the sliding slot 15 until the bottom surface of the upper baffle 18 can contact the upper surface of the welding part. When the vertical sliding block 16 slides in the sliding slot 15, the vertical indicator needle 17 will slide along with the vertical sliding block 16. The vertical indicator needle 17 can correspond to the position of the vertical measuring ruler 24 to facilitate the inspection and measurement of the vertical dimension of the welding part. Moreover, since the vertical measuring ruler 24 is marked at the position corresponding to the reasonable tolerance dimension of the welding part, the reasonable tolerance vertical dimension of the welding part can be quickly inspected and measured, so that the inspection fixture can be used to inspect and measure the dimensions of the welding part, thereby improving the inspection efficiency of the inspection fixture.
