It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] See also Figures 1 to 5 An embodiment of the present invention provides a riveting and welding tool for the underframe of a self-propelled aerial work platform, which includes a tooling plate 1, two pairs of supports 2 connected to both ends of the top surface of the tooling plate 1, multiple pairs of positioning ribs 3 vertically arranged on the top surface of the tooling plate 1 along the length direction of the tooling plate 1, and a height-fixing plate 4 vertically connected to the top surface of the tooling plate 1 on both sides of a pair of supports 2 at one end.

[0021] A U-shaped slot is provided at the top of the support 2, and a first movable core shaft 5 is clamped in the U-shaped slot of each pair of supports 2. Two pairs of height-fixing plates 4 are provided, and a second movable core shaft 6 is placed horizontally on the top of each pair of height-fixing plates 4. The first movable core shaft 5 and the second movable core shaft 6 are both parallel to the top surface of the tooling plate 1, and the top surface of the tooling plate 1 on the inner side of the bottom of the two pairs of positioning ribs 3 at both ends are respectively fixed with a pad 7.

[0022] The two ends of the left side plate 01 and the right side plate 02 of the chassis of the self-propelled aerial work platform are raised by the raising blocks 7. In the embodiment of the present invention, four pairs of positioning ribs 3 are provided and are evenly distributed along the length direction of the top surface of the tooling plate 1. The distance between the two opposite positioning ribs 3 is slightly larger than the width of the chassis of the self-propelled aerial work platform. The left side plate 01 contacts the positioning surface formed by the four positioning ribs 3 on one side, and the right side plate 02 does not contact the positioning surface formed by the four positioning ribs 3 on the other side, with a gap. It is clamped by a wedge block to ensure the opening size of the left side plate 01 and the right side plate 02, and can ensure that the left side plate 01 and the right side plate 02 are parallel to the top surface of the tooling plate 1, providing a reference for the later milling of the flange surface 012.

[0023] In addition, the positioning ribs 3 have a trapezoidal structure, and the lower bases of the trapezoidal structures of each pair of positioning ribs 3 are arranged relative to each other to ensure structural strength.

[0024] The two ends of the two first movable core shafts 5 are respectively inserted into the first through holes 010 on the first ear plate 03 and the first partition plate 05, and the first through holes 010 on the fourth partition plate 08 and the fifth partition plate 09, to ensure the coaxiality of the two groups of first through holes 010, and the two ends of the two second movable core shafts 6 are respectively inserted into the two groups of second through holes 011 on the first ear plate 03 and the second ear plate 04, to ensure the coaxiality and parallelism of the two groups of second through holes 011, and the first movable core shaft 5 and the second movable core shaft 6 are positioned and fixed by the U-shaped slot of the support 2, to ensure the position size and parallelism of the first through hole 010 and the second through hole 011.

[0025] Two pairs of positioning plates 8 are provided on both sides of the support 2 close to the height-fixing plate 4 , and a pair of positioning plates 8 are provided on both sides of the support 2 away from the height-fixing plate 4 . The positioning plates 8 are vertically connected to the top surface of the tooling plate 1 .

[0026] The positioning plate 8 is respectively in contact with the first ear plate 03 , the first partition plate 05 and the fifth partition plate 09 to ensure the position accuracy of the first ear plate 03 , the first partition plate 05 and the fifth partition plate 09 .

[0027] Two groups of height-fixing blocks 9 are provided between the two pairs of supports 2 . Each group of height-fixing blocks 9 has four blocks with the same height. The four height-fixing blocks 9 are arranged in a rectangular shape. The height-fixing blocks 9 are vertically connected to the top surface of the tooling plate 1 .

[0028] The top of the height-fixing block 9 contacts and supports the bottom plate 013 , ensuring the position, size and parallelism of the bottom plate 013 and the first, second, third and fourth partitions 05 , 06 , 07 and 08 abutting against the bottom plate 013 .

[0029] A pair of height-fixing frames 10 of the same height are provided on both sides of the support 2 away from the height-fixing plate 4 . The two height-fixing frames 10 are parallel to each other and vertically connected to the top surface of the tooling plate 1 .

[0030] The top of the fixed height frame 10 contacts and supports the support plate 014 , ensuring the position and parallelism of the support plate 014 and the fourth partition plate 08 and the fifth partition plate 09 abutting against the support plate 014 .

[0031] The dimensions of the various components in the riveting and welding tooling for the chassis of the self-propelled aerial work platform provided in the aforementioned embodiment of the present invention, as well as the dimensions between the components, can be set according to the dimensions of a standard chassis or the dimensions of a required chassis.

[0032] In summary, when the self-propelled aerial work platform chassis riveting and welding fixture provided by the embodiment of the present invention is used, the left side plate 01 and the right side plate 02 are first positioned using the four spacers 7 on the top surface of the fixture plate 1 and the positioning ribs 3 on the left and right sides to ensure that the left side plate 01 and the right side plate 02 are perpendicular to the top surface of the fixture plate 1, providing a reference for the subsequent milling of the flange surface 012. Then, the first ear plate 03, the second ear plate 04, the first partition plate 05, the bottom plate 013, the second partition plate 06, the third partition plate 07, the fourth partition plate 08, the support plate 014, the fifth partition plate 09 and the flange surface 012 are assembled. The first ear plate 03, the first partition plate 05, and the fifth partition plate 09 are respectively abutted against the positioning plate 8, the height setting block 9 is abutted against the bottom plate 013, and the height setting frame 10 is abutted against the support plate 014. The left side panel 01 is positioned against the positioning surface formed by the left positioning rib 3. The right side panel 02 is spaced slightly apart from the positioning surface formed by the right positioning rib 3 and clamped with wedges to ensure the gap size between the left and right side panels. The two first movable mandrels 5 and the two second movable mandrels 6 are then threaded to ensure the coaxiality and parallelism of the two sets of first through-holes 010, the coaxiality of the two sets of second through-holes 011, and the position, size, and parallelism of the first through-holes 010 and the second through-holes 011, thus completing the overall positioning of the chassis.
