DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses a metal workpiece spraying positioning fixture. Figure 1-4A metal workpiece spray positioning fixture includes a base 1, a top outer wall of the base 1 is fixedly connected to a plurality of fixed columns 2, the outer wall of the fixed column 2 is installed with an inner support assembly for fixing the workpiece, the inner support assembly includes a load-bearing ring 4 slidably connected to the outer wall of the fixed column 2, and a fixed block 3 fixedly connected to the outer wall near the top end of the fixed column 2, a plurality of first connecting rods 5 are hinged to the bottom outer wall of the fixed block 3, a plurality of second connecting rods 8 are hinged to the top outer wall of the load-bearing ring 4, the second connecting rod 8 is movably connected to a connecting piece 6 at one end opposite to the first connecting rod 5, and the outer walls of the plurality of connecting pieces 6 are fixedly connected to an inner support plate 7.

[0023] The outer walls of the multiple fixed columns 2 are slidably connected with a connecting ring 9, and the top outer walls of the connecting ring 9 are fixedly connected with multiple top rings 10. The multiple top rings 10 correspond to the multiple fixed columns 2, and the top rings 10 are slidably connected to the outer walls of the fixed columns 2. The connecting ring 9 and the multiple top rings 10 are both located below the multiple supporting rings 4.

[0024] A plurality of cylinders 11 are embedded and installed in the outer wall of the base 1 , and the output ends of the plurality of cylinders 11 are fixedly connected to the bottom outer wall of the connecting ring 9 .

[0025] A plurality of fixing feet 12 are fixedly connected to the bottom outer wall of the base 1 , and the plurality of fixing feet 12 are evenly distributed on the bottom outer wall of the base 1 in a circular array with equal spacing.

[0026] The plurality of cylinders 11 are evenly distributed on the bottom outer wall of the base 1 in a circular array with equal spacing, and the plurality of cylinders 11 and the plurality of fixing legs 12 are staggered with each other.

[0027] A plurality of fixing posts 2 are evenly distributed on the top outer wall of the base 1 in a circular array with equal spacing.

[0028] The implementation principle of a metal workpiece spray positioning fixture in the embodiment of the present application is as follows: when in use, the base 1 can be fixed in a suitable position through multiple fixed feet 12, and multiple metal workpieces are sleeved on the surfaces of multiple inner support plates 7 on multiple fixed columns 2, and their bottom ends are in contact with the carrying ring 4, and then the cylinder 11 is started, and the output end of the cylinder 11 drives the connecting ring 9 to rise, and the connecting ring 9 drives multiple top rings 10 to lift the multiple carrying rings 4 upward. When the carrying ring 4 rises, it cooperates with the fixed block 3 to squeeze the second connecting rod 8 and the first connecting rod 5, and the second connecting rod 8 and the first connecting rod 5 will rotate, and the opposite end thereof pushes the connecting piece 6 outward, and the connecting piece 6 drives the inner support plate 7 to expand outward. At this time, the multiple inner support plates 7 expand outward synchronously and contact the inner wall of the metal workpiece to clamp the workpiece internally, so as to facilitate the positioning and clamping of multiple workpieces;

[0029] Then, multiple workpieces can be sprayed through external spraying equipment. Since the inner support plate 7 in the inner support assembly does not contact the surface of the workpiece, it will not affect the spraying uniformity of the workpiece surface. After the spraying is completed, the output end of the cylinder 11 contracts and drives the connecting ring 9 to descend, and the top ring 10 no longer lifts the supporting ring 4. The supporting ring 4 slides down under the action of gravity. At this time, the supporting ring 4 pulls the second connecting rod 8 and the first connecting rod 5, and the second connecting rod 8 and the first connecting rod 5 rotate, and their opposite ends will pull the connecting member 6 to move inward, and the connecting member 6 will drive the inner support plate 7 to contract. Multiple inner support plates 7 shrink synchronously and will not contact the inner wall of the metal workpiece, thereby releasing the fixation of the metal workpiece and facilitating the removal of multiple workpieces.
