Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The adjusting component 9 is used to cooperate with the positioning cylinder 8 to adjust the distance between each group of upper carrying plates 6 and the lower carrying plates 7, the outer side of the upper carrying plate 6 is fixedly connected with an upper support rod 10, and the outer side of the lower carrying plate 7 is fixedly connected with a lower limit plate 11;

[0029] Among them, one end of the inner cavity of the shot blasting box 1 is connected to a pick-up door through a hinge, and an observation window is opened in the middle of the pick-up door. A transparent observation plate is fixedly connected to the inside of the observation window. The setting of the observation window can intuitively feedback the real-time status of the inner cavity of the shot blasting box 1, so as to help the staff analyze the shot blasting progress of the bolts;

[0030] Example 2

[0031] like Figures 1 to 6 As shown, based on the same concept as the above embodiment 1, this embodiment further proposes an adjustment component 9;

[0032] In this embodiment, the adjustment assembly 9 includes a central shaft 12, a threaded section 13, a transmission shaft 14, a transmission spur gear 15, a reduction spur gear 16 and a transmission cylinder 18. The central shaft 12 is rotatably connected between the middle of the stabilizing disk 3 and the transmission disk 4. The outer side of the central shaft 12 is provided with a threaded section 13 corresponding to the positioning cylinder 8. The threaded section 13 is located inside the corresponding positioning cylinder 8. The bottom end of the transmission disk 4 is rotatably connected to the transmission shaft 14. One end of the transmission shaft 14 located inside the transmission disk 4 is fixedly connected to the transmission spur gear 15. One end of the central shaft 12 located inside the transmission disk 4 is fixedly connected to the reduction spur gear 16, and the reduction spur gear 16 is meshed with the transmission spur gear 15. The interior of the positioning cylinder 8 is rotatably connected to the transmission cylinder 18, and the transmission cylinder 18 is also threadedly connected to the outer side of the corresponding threaded section 13;

[0033] Furthermore, a force knob is fixedly connected to the bottom end of the transmission shaft 14, and an anti-slip groove is provided on the outside of the force knob. The force knob is provided so that it is easy for people to hold, thereby ensuring the transmission efficiency of the transmission shaft 14.

[0034] Among them, the bottom end of the interior of the positioning cylinder 8 is fixedly connected with a stabilizing ring 17, and the bottom end of the outer side of the conductive cylinder 18 is provided with an annular groove. The stabilizing ring 17 is assembled inside the annular groove, and a plurality of alloy balls are further provided at the connection between the stabilizing ring 17 and the annular groove. The structural cooperation between the stabilizing ring 17 and the conductive cylinder 18 can stably support the conductive cylinder 18 and prevent the conductive cylinder 18 from uncontrollable movement inside the stabilizing ring 17;

[0035] Specifically, a threaded through hole is formed in the middle of the conductive tube 18, and the conductive tube 18 is connected to the outer side of the threaded segment 13 through the threaded through hole. By virtue of the arrangement of the threaded through hole, when the central shaft 12 drives the threaded segment 13 to rotate, the conductive tube 18 can cooperate with the conductive tube 18, so that the conductive tube 18 moves along the central shaft 12;

[0036] The adjustment assembly 9 also includes an extension seat 19, a transmission screw 20, a displacement push plate 21 and a rotation-stopping rod 22. The bottom end of the outer side of the positioning cylinder 8 is fixedly connected to the extension seat 19, the inner side of the extension seat 19 is rotatably connected to the transmission screw 20, the outer side of the transmission screw 20 is threadedly connected to the displacement push plate 21, and the top and bottom ends of the displacement push plate 21 are fixedly connected to the rotation-stopping rod 22, and one end of the rotation-stopping rod 22 extends into the interior of the positioning cylinder 8 and is clamped and connected to the conductive cylinder 18;

[0037] In order to prevent the linear guide rod 5 from interfering with the extension seat 19 from revolving along the central shaft 12, the distance between the linear guide rod 5 and the central shaft 12 is greater than the length of the extension seat 19.

[0038] Preferably, a plurality of locking holes corresponding to the anti-rotation rod 22 are opened on the outer side of the conductive tube 18, and the anti-rotation rod 22 is snap-connected to the inside of the locking hole. By utilizing the setting of the locking hole, when the anti-rotation rod 22 is connected to the conductive tube 18, it can be snapped into the inside of the locking hole to ensure the connection effect between the anti-rotation rod 22 and the conductive tube 18.

[0039] A specific application of the above two embodiments is to first assemble the bolt on the upper support rod 10 and the lower limit plate 11, and then use an external power source to drive the transmission plate 4 to rotate to adjust the position of the bolt toward the steel shot outlet end of the shot blasting machine 2, and then the steel shot is sprayed toward the bolt through the shot blasting machine 2 to process the surface of the bolt;

[0040] When the distance between the positioning cylinders 8 needs to be adjusted, the transmission screw 20 at the position where the positioning cylinder 8 does not need to be moved is first rotated, and the transmission screw 20 is connected to the displacement push plate 21, so that the displacement push plate 21 can drive the anti-rotation clamping rod 22 to separate from the conductive cylinder 18, thereby releasing the rotation restriction of the conductive cylinder 18;

[0041] Then, the transmission shaft 14 is rotated to cause the transmission spur gear 15 to shift the reduction spur gear 16, thereby driving the central shaft 12 to rotate. In conjunction with the connection between the conductive cylinder 18 and the threaded segment 13, the conductive cylinder 18 that is released by the anti-rotation clamping rod 22 will rotate with the threaded segment 13. The conductive cylinder 18 that is not restricted by the anti-rotation clamping rod 22 cannot follow the rotation, and thus can drive the corresponding positioning cylinder 8 to move outside the threaded segment 13, thereby adjusting the distance between the positioning cylinders 8 to meet the assembly needs of bolts of different specifications. When the positioning cylinder 8 is displaced, the threaded segment 13 can be protected by the positioning cylinder 8, so that the threaded segment 13 will not be exposed, thereby avoiding damage to the threaded segment 13.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
