[0025] Example: as Figure 1 - Figure 6As shown, a kind of engineering machinery swing frame machining tooling includes lower clamping plate 1 and upper clamping plate 9, and also includes two inner clamping plates 4, lower clamping plate 1 and upper clamping plate 9 are clamped to flat-lying plate body, two inner clamping plates 4 are clamped to vertical plate body, two inner side walls of lower clamping plate 1 are fixedly connected with positioning shaft 2, the bottom of inner clamping plate 4 is fixedly connected with sliding plate 3, the inside of sliding plate 3 is provided with positioning hole 30, sliding plate 3 is slidably connected with positioning shaft 2 by positioning hole 30, sliding plate 3 and inner clamping plate 4 are perpendicular to each other, the top of inner clamping plate 4 is rotatably connected with rotating arm 5, the bottom of rotating arm 5 is fixedly connected with upper clamping plate 9, the positioning of supporting plate or reinforcing rib plate can be carried out by the mutual clamping of lower clamping plate 1 and upper clamping plate 9, the positioning of first support plate or second support plate can be carried out by the clamping to the middle of two inner clamping plates 4, to ensure that the plane clamped by two sets of clamps is always in vertical state, inner clamping plate 4 is extended downward into ninety-degree folding sliding plate 3, positioning hole 30 is arranged in parallel in the inside of sliding plate 3, sliding plate 3 is fixed on positioning shaft 2 by positioning hole 30, and horizontal sliding is carried out under the guidance of positioning shaft 2, at this time, no matter how two inner clamping plates 4 move, inner clamping plate 4 and sliding plate 3 are in vertical state, so the clamping direction of two sets of clamps is in vertical direction, then rotating arm 5 is rotated along the connecting point of inner clamping plate 4, and upper clamping plate 9 is moved by rotating arm 5, so that upper clamping plate 9 is clamped and positioned close to lower clamping plate 1, in summary, two sets of clamps are fixed on a machining tooling, can quickly and conveniently position swing frame and supporting plate at bottom corner, so that the fixed welding process of swing frame is more efficient and more accurate.

[0026] According to Figure 3 As shown, sliding plate 3 and inner clamping plate 4 are integrally formed, and sliding plate 3 and inner clamping plate 4 are prepared by integral forming, so that the perpendicular structure formed by sliding plate 3 and inner clamping plate 4 is not easy to deform, thereby improving the positioning accuracy.

[0027] According to Figure 2 As shown, the bottom of upper clamping plate 9 is fixedly connected with flexible pad 12, and upper clamping plate 9 keeps the upper and lower clamping surfaces of plate body parallel by flexible pad 12 and lower clamping plate 1, since upper clamping plate 9 is clamped with lower clamping plate 1 by the rotation of rotating arm 5, there is a distance difference in movement between the inner edge and the outer edge of upper clamping plate 9 due to the difference in arc length, so that the clamping plane formed by upper clamping plate 9 and lower clamping plate 1 is not parallel, the effective clamping area is reduced, and the positioning effect is affected, especially the greater the thickness of the clamping surface, the greater the clamping deviation, in order to enhance the clamping effect, flexible pad 12 is arranged at the bottom of upper clamping plate 9, and the deformation of flexible pad 12 is used to compensate for the deviation between the inner edge and the outer edge of the clamping surface, to increase the clamping and fixing effect.

[0028] According to Figure 1As shown, the top end of the two inner clamping plates 4 is fixedly connected with an extension frame 6, one of the extension frames 6 is fixedly connected with a rotating seat 10, and the other extension frame 6 is fixedly connected with a threaded seat 11. The spacing of the two groups of inner clamping plates 4 is controlled through threaded connection, which can better adjust the clamping thickness.

[0029] According to Figure 1 As shown, the side wall of the rotating seat 10 is rotationally connected with a lead screw 7, and the outer side wall of the lead screw 7 is threadedly connected with the threaded seat 11. When the machining tool is positioned on the support plate, the lead screw 7 is manually rotated to drive the threaded seat 11 to move, so that the threaded seat 11 is close to the rotating seat 10, and the two inner clamping plates 4 below clamp the support plate.

[0030] According to Figure 4 As shown, the surface of the rotating arm 5 is provided with a sleeve hole 8. The sleeve hole 8 is provided on the surface of the rotating arm 5, so as to adjust the rotation angle of the rotating arm 5 by cooperating with the sleeve hole 8 by using a tool. For example, a wrench is sleeved on the sleeve hole 8 to increase the arm, so that the rotating arm 5 can be easily controlled to be pressed downward.

[0031] According to Figure 4 As shown, the top end of the inner clamping plate 4 is provided with a buckle groove 14, and the top end of the rotating arm 5 is fixedly connected with a buckle disc 13. The buckle disc 13 and the buckle groove 14 are rotationally connected. The rotating arm 5 is buckled on the outer side of the inner clamping plate 4 through the buckle disc 13, so that the rotating arm 5 can rotate circumferentially around the buckle groove 14, and the rotating arm 5 and the inner clamping plate 4 are not easily separated.

[0032] The working principle and use method of the device are as follows: first, the supporting plate or the reinforcing rib plate of the swing frame is placed on the lower clamping plate 1, and the support plate of the swing frame is placed between the two inner clamping plates 4;

[0033] Then, the lead screw 7 is manually rotated to drive the threaded seat 11 to move, so that the two inner clamping plates 4 below clamp the support plate;

[0034] Subsequently, the wrench is sleeved on the sleeve hole 8, and the wrench is used to press the rotating arm 5 downward. The rotating arm 5 rotates circumferentially around the buckle groove 14 until the upper clamping plate 9 at the bottom of the rotating arm 5 clamps the supporting plate or the reinforcing rib.

[0035] Finally, the supporting plate or the reinforcing rib plate of the swing frame and the support plate of the swing frame are positioned. At this time, the support plate and the supporting plate or the reinforcing rib plate can be welded and fixed by using a welding tool.
