Specific embodiments

[0021] The present invention will be further described below in conjunction with the drawings and embodiments.

[0022] The vehicle vertical side frame translation-in-place locking mechanism of the present invention, as shown in Figure 1 and Figure 2 , includes a left column 1 and a right column 2. The left column 1 and the right column 2 are used to support other components, and are made of columnar and frame structures with relatively high strength. As a preferred embodiment, as shown in Figure 5 , the left column 1 and the right column 2 are hollow columns, and the hollow columns are formed by welding four plates together. The plates can be conventional carbon steel plates, so that the cross-sections of the left column 1 and the right column 2 are rectangular rings. The left column 1 and the right column 2 with such a structure have strong supporting capabilities, relatively light weights, and relatively simple manufacturing processes. In order to keep the positions of the left column 1 and the right column 2 fixed, the left column 1 and the right column 2 can be fixed on the same base, and the base can be fixed to the floor of the workshop through anchor bolts. Specifically, the bottom of the left column 1 and the right column 2 is provided with a bottom plate 17, and the edge of the bottom plate 17 is provided with a mounting plate 18. The bottom plate 17 can be connected to the mounting plate 18 through bolts, and the mounting plate 18 is connected to the base through bolts. In addition, the left column 1 and the right column 2 can also be directly welded to the base.

[0023] A first end face pressing plate 3 is arranged at the upper part of the left column 1, and a second end face pressing plate 4 is arranged at the lower part of the left column 1. Both the first end face pressing plate 3 and the second end face pressing plate 4 are connected with an end face pressing drive mechanism 19. The first end face pressing plate 3 and the second end face pressing plate 4 are used for pressing the left end face of the vertical side frame 100, and the end face pressing drive mechanism 19 is used for driving the first end face pressing plate 3 and the second end face pressing plate 4 to move horizontally, so as to realize the pressing and loosening of the first end face pressing plate 3 and the second end face pressing plate 4. Specifically, the end face pressing drive mechanism 19 can adopt a cylinder. The cylinder block of the cylinder is fixed on the left column 1 through bolts, and the piston rod of the cylinder is fixedly connected with the first end face pressing plate 3 or the second end face pressing plate 4.

[0024] A z-direction support wheel 5 is arranged at the lower part of the right column 2. The axis of the z-direction support wheel 5 is horizontal. A side limiting mechanism 6 is arranged on one side of the z-direction support wheel 5, and a first pressing head 7 is arranged on the other side. The first pressing head 7 is connected with a first locking drive mechanism 8. An x-direction guiding wheel 9 is arranged at the upper part of the right column 2. The axis of the x-direction guiding wheel 9 is vertical. A second pressing head 10 is arranged on one side of the x-direction guiding wheel 9, and the second pressing head 10 is connected with a second locking drive mechanism 12.

[0025] In the present utility model, the x-direction is consistent with the length direction of the vertical side frame 100, the y-direction is consistent with the width direction of the vertical side frame 100, and the z-direction is the vertical direction. The z-direction support wheel 5 can rotate around its own central axis, and is used for supporting the lower end face of the vertical side frame 100, limiting the lower end face of the vertical side frame 100, and guiding the vertical side frame 100 during the translation process. The side limiting mechanism 6 and the x-direction guiding wheel 9 are used for supporting one side of the vertical side frame 100, and the first pressing head 7 and the second pressing head 10 are used for pressing the other side of the vertical side frame 100, so as to position the vertical side frame 100 in the y-direction. The x-direction guiding wheel 9 can also rotate around its own central axis, and can guide the vertical side frame 100 during the translation process of the vertical side frame 100. A translation positioning space is formed between the side limiting mechanism 6 and the first pressing head 7 and between the x-direction guiding wheel 9 and the second pressing head 10. The z-direction support wheel 5 is located in the translation positioning space, and the first end face pressing plate 3 and the second end face pressing plate 4 are also located in the translation positioning space. The first locking drive mechanism 8 and the second locking drive mechanism 12 are used for driving the first pressing head 7 and the second pressing head 10 to move along the y-direction and providing a locking pressure, so that the first pressing head 7 and the second pressing head 10 can press and lock the vertical side frame 100.

[0026] When using the present utility model, the vertical side frame 100 is lifted by a hoisting device and transported to the translation positioning space, and then the vertical side frame 100 is lowered so that one end of the vertical side frame 100 lands on the z-direction support wheel 5, and one side surface of the vertical side frame 100 contacts the x-direction guide wheel 9. Then, the vertical side frame 100 is pushed to move horizontally in the direction of the right column 2 until the right end of the vertical side frame 100 abuts against the right column 2 or the components on the right column 2. Then, the end surface pressing drive mechanism 19 is used to push the first end surface pressing plate 3 and the second end surface pressing plate 4 to move horizontally in the direction of the right column 2 to press the left end surface of the vertical side frame 100, realizing the x-direction locking of the vertical side frame 100; further, the first locking drive mechanism 8 and the second locking drive mechanism 12 are used to drive the first pressing head 7 and the second pressing head 10 to move in the direction of the vertical side frame 100 to press the side surface of the vertical side frame 100, realizing the y-direction locking of the vertical side frame 100, and the vertical side frame 100 can be kept fixed.

The first mounting beam 15 and the second mounting beam 16 are cantilever beams, and one end of them can be welded to the right column 2.

[0029] The first mounting beam 15 and the second mounting beam 16 can adopt hollow beams, and the cross-sectional shape thereof is the same as the cross-sectional shape of the right column 2.

[0030] The first connection seat 13 and the second connection seat 14 are installed by screws, which is convenient for disassembly and assembly.

[0031] Such as Figure 2 、 Figure 3 and Figure 4As shown, both the first locking drive mechanism 8 and the second locking drive mechanism 12 include a cylinder 81, a mounting seat 82, a transmission arm 83 and a connecting plate 84. The mounting seat 82 is detachably mounted on the right column 2. The cylinder block of the cylinder 81 is hinged to the mounting seat 82. The middle of the transmission arm 83 is hinged to the mounting seat 82. One end of the transmission arm 83 is hinged to the piston rod of the cylinder 81. The other end of the transmission arm 83 is fixedly connected to the connecting plate 84. The first pressing head 7 and the second pressing head 10 are fixedly mounted on the connecting plate 84. When the piston rod of the cylinder 81 extends, it will push the transmission arm 83 to rotate. The transmission arm 83 can drive the connecting plate 84 and the first pressing head 7 or the second pressing head 10 to move, so that the first pressing head 7 or the second pressing head 10 presses against the side surface of the vertical side frame 100.

[0032] The mounting seat 82 can be welded to the right column 2 or can be mounted on the right column 2 by screws.
