[0002] The shot peening treatment of gears is an effective surface strengthening technology, which can significantly improve the strength, hardness and fatigue life of gears. Through the impact of high-speed steel shots, the martensite microstructure on the gear surface layer is refined, the dislocation density is increased, and the lattice distortion is aggravated, thus causing work hardening. This process can transform retained austenite into twin martensite, which has an obvious strengthening effect on the improvement of gear strength. The Chinese utility model patent with the application number 202323103347.2 discloses a shot peening machine for gear processing, including a box body. A reduction motor is fixedly installed in the middle of the top of the box body. The outer part of the output shaft of the reduction motor is fixedly connected with a clamping cylinder located inside the box body. A hanging frame assembly is movably clamped inside the clamping cylinder. Support plates are fixedly installed at the lower ends of the left and right sides of the box body. A feeding assembly is fixedly installed on the top of the support plates.

[0003] For the above-mentioned shot peening machine for gear processing, by mounting gear workpieces on the hanging frame assembly in a staggered arrangement, the mounting quantity is increased. At the same time, through the staggered arrangement of the inner fixing rods, the contact area between the shot peening and the gears is ensured, and the treatment effect and efficiency of the shot peening are improved. However, it is found that there are defects in the use process: although the hanging frame assemblies are arranged in a staggered manner, each hanging frame assembly is fixed and cannot rotate, and there are areas that cannot be processed; moreover, the bearings are only hung on it and cannot be fixed to the hanging frame as a whole, and they are prone to pile up with each other, which is not conducive to the comprehensiveness of the treatment.

Embodiment 1

[0030] As Figures 1 to 4 shown, a gear shot blasting tooling for a shot blasting machine includes a cylindrical barrel 1 with upper and lower openings in the middle vertically.

The suspension structure 2 includes a horizontal support plate 21 fixed inside the cylindrical barrel 1. A vertical plate 22 is fixed on the upper surface of the support plate 21. Motors 23 are arranged back to back on the support plate 21 on the left and right sides of the vertical plate 22. The motor shafts outside the motors 23 are fixedly connected to the inner ends of circular support rods 25 through couplings 24. The support rods 25 can rotatably pass through the cylindrical barrel 1 and a tensioning structure cooperating with bearings is arranged on the passing part. Sealing covers 3 are respectively clamped at the upper and lower ends of the cylindrical barrel 1. A vertical rubber tube 4 is embedded on one side of the upper sealing cover 3. A power cord 5 electrically connected to the motor 23 is arranged in the rubber tube 4. An arc-shaped lifting lug 11 is fixedly arranged at the upper end of the cylindrical barrel 1.

[0031] The tensioning structure includes a cross bar 26 arranged above the support rod 25 on the outer side of the cylindrical barrel 1. Square blind holes 261 are embedded at the bottom ends of both ends of the cross bar 26. A screw 28 is screwed up from the bottom on the support rod 25 below the square blind holes 261. A cross-shaped screwing groove (not shown) is arranged on the bottom surface of the screw 28. The axial width of the square blind hole 262 along the cross bar 26 is greater than the diameter of the screw 28. When the screw 28 is pushed up, the cross bar 26 can be tilted. After screwing and pushing on one side, the other side can be screwed, and finally the cross bar 26 can be adjusted to be balanced.
