[0014] Figure 2 It is the front view of the present utility model.

[0015] Wherein: long rod 1; left support frame 2; right support frame 3; bearing support 4; left positioning ring 5; right positioning ring 6; spacer ring 7; workpiece 8; ball bearing 9; clamp 10; positioning bolt 11; connecting ring 12; compression nut 13; compression bolt 14; gasket 15. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Refer to Figure 1 and Figure 2 , the present utility model relates to a dry film spraying tooling fixture for bearings, which includes a long rod 1, a left support frame 2, a right support frame 3, a bearing support 4, a left positioning ring 5, a right positioning ring 6, a spacer ring 7 and a workpiece 8. The left end of the long rod 1 is rotatably arranged in the bearing support 4 through a ball bearing 9. The long rod 1 rotates through the ball bearing 9 at the left end, driving multiple workpieces 8 thereon to rotate, so as to ensure the uniform spraying of the workpieces during the spraying process. The bearing support 4 is supported by the left support frame 2. The long rod 1 is sleeved with a workpiece 8, a left positioning ring 5, a spacer ring 7 and a right positioning ring 6. Multiple workpieces 8 are arranged between the left positioning ring 5 and the right positioning ring 6. Adjacent workpieces 8 are separated by a spacer ring 7. The left positioning ring 5 is pressed by a pressing assembly, and the right positioning ring 6 is fixed to the long rod 1 through a positioning bolt 11. The radially arranged positioning bolt 11 passes through the right positioning ring 6 and the long rod 1 and is locked by a nut.

[0017] The pressing assembly includes a connecting ring 12, a compression nut 13, a compression bolt 14 and a gasket 15. The connecting ring 12 is sleeved and fixed on the long rod 1. The compression nuts 13 are evenly welded circumferentially on the connecting ring 12. The compression bolts 14 are arranged in the compression nuts 13. Multiple compression bolts 14 abut against the gasket 15. The gasket 15 is arranged on the left side of the left positioning ring 5. By adjusting the compression bolts 14, multiple compression bolts 14 push the gasket 15 to tightly press the left positioning ring 5.

[0018] The right end of the long rod 1 is a free end. During assembly, a gasket 15, a left positioning ring 5, a workpiece 8, a spacer ring 7, and a right positioning ring 6 are sequentially inserted through the right end of the long rod. The spacer ring 7 is arranged between two adjacent workpieces 8 to separate the workpieces 8, prevent part interference during the dry film spraying process, and can, to a certain extent, shield and protect the end faces of the bearing parts. After the workpiece is clamped, the positioning bolt 11 first fixes the right positioning ring 6 to the long rod 1, and then the compression bolt 14 is adjusted. The compression bolt 14 pushes the gasket 15 to tightly press against the left positioning ring 5, thereby fixing the position of the workpiece and preventing the part group from sliding during the spraying process and affecting the spraying quality.

[0019] The right end of the long rod 1 as the free end is supported by the right support frame 3. The right support frame 3 and the left support frame 2 cooperate to jointly support the long rod 1, facilitating the spraying operation for workers.

[0020] There are two ball bearings 9. The two ball bearings are arranged at both ends of the bearing support 4. The ball bearings are positioned by snap rings. Both ends of the upper and lower split bearing support 4 are connected into one body by a clamp 10.

[0021] In addition to the above embodiments, the present invention also includes other implementation manners. Any technical solutions formed by equivalent transformation or equivalent substitution shall fall within the protection scope of the claims of the present invention.
