[0038] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0039] See also Figure 1-Figure 5 This embodiment discloses a suspended shot blasting machine, including a shot blasting machine body 101 and a feeding mechanism 102, wherein the feeding mechanism 102 is used to feed a brake drum 103 to be processed into the shot blasting machine body 101 for shot blasting, and the feeding mechanism 102 includes a feeding unit 104, a manipulator 105, a crossbeam 106, and a chain transmission mechanism arranged on the crossbeam 106, wherein a plurality of hangers 108 are suspended on the chain transmission mechanism;

[0040] The feeding unit 104 is used to sequentially feed the brake drum 103 to the manipulator 105;

[0041] The manipulator 105 is used to sequentially hang the brake drum 103 at the feeding unit 104 on the hanger 108;

[0042] The chain transmission mechanism is used to deliver the hanger 108 on which the brake drum 103 is suspended to the shot blasting machine body 101 for shot blasting operation;

[0043] Among them, the hanger 108 includes a protective plate 109, a hook 110 arranged on the protective plate 109 for connecting with a chain transmission mechanism, a fixed shaft 111 fixedly arranged on the lower side of the protective plate 109, a rotating shaft 112 coaxially arranged on the fixed shaft 111, and a support rod 113 arranged on the rotating shaft; a limiting mechanism 114 for limiting the rotation of the protective plate 109 is arranged on the chain transmission mechanism; after the brake drum 103 is hung on the support rod 113, the hanger can rotate during the shot blasting process.

[0044] The present invention can realize the automatic shot blasting treatment of the brake drum 103 in actual use. The brake drum 103 is sent to the manipulator 105 through the provided feeding unit 104, and the brake drum 103 is successively hung on the hanger 108 through the manipulator 105, and the brake drum 103 is sent to the shot blasting machine body 101 for shot blasting under the action of the chain transmission mechanism, thereby realizing the automatic treatment of the brake drum 103; at the same time, because the fixed shaft 111 is hung on the hook 110 connected to the chain transmission mechanism through the protective plate 109, and under the limitation of the limiting mechanism 114, the rotating shaft 112 can rotate on the fixed shaft 111, and then the rotating shaft 112 can drive the brake drum 103 to rotate during the shot blasting process, thereby realizing multi-angle treatment of the brake drum 103 and improving the treatment effect.

[0045] Among them, the limiting mechanism 114 includes a connecting rod 124, a fixed plate 125 and a first hook. The fixed plate 125 is connected to the connecting rod 124. The connecting rod 124 is used to connect to the chain transmission mechanism. The first hook is arranged on the fixed plate 125 and is used to connect to the hook 110. A limiting hole 126 is arranged on the fixed plate 125, and a limiting rod 127 capable of passing through the limiting hole 126 is arranged on the protective plate 109.

[0046] The fixed plate 125 is installed on the chain transmission mechanism through the first hook, so that the chain transmission mechanism drives the fixed plate 125 to move, and the protective plate 109 is fixed under the action of the limit rod 127, so that the brake drum 103 on the rotating shaft 112 can be rotated after being impacted during the shot blasting process, thereby realizing multi-angle shot blasting treatment of the brake drum 103.

[0047] Furthermore, the manipulator 105 is a six-degree-of-freedom arm manipulator, and the purpose of automatic loading is achieved by setting the six-degree-of-freedom arm manipulator 105.

[0048] In actual use, since the rotating shaft 112 rotates, manual assistance can be used when loading materials using the six-degree-of-freedom arm manipulator 105 to improve the accuracy of loading materials. For example, the rotating shaft 112 is rotated to a suitable position so that the brake drum 103 can be hung on the support rod 113.

[0049] Furthermore, the support rod 113 is in a truncated cone shape, and the large end of the support rod 113 is away from the rotating shaft 112; such a configuration enables the brake drum 103 to slide toward the small end of the support rod 113, thereby preventing the brake drum 103 from falling.

[0050] In actual use, a limiting boss 115 is provided on the support rod 113 to limit the position of the brake drum 103 .

[0051] Furthermore, the fixed shaft 111 and the rotating shaft 112 are rotatably connected via a bearing 116 .

[0053] Further, there are multiple support rods 113, and they are arranged on the rotating shaft 112 in sequence from top to bottom. Among them, the support rods 113 are staggered on the rotating shaft 112. To ensure that the brake drum 103 can be shot blasted in all directions.

[0054] In some preferred implementation cases, a shell 117 is fixedly provided on the rotating shaft 112, an extension portion 118 is provided on the shell 117, the support rod 113 is rotatably installed on the extension portion 118, a first bevel gear 119 is provided at the end of the support rod 113 located in the shell 117, and a second bevel gear 120 is fixedly provided on the fixed shaft 111 located in the shell 117, and the first bevel gear 119 and the second bevel gear 120 are meshed with each other.

[0055] This arrangement enables the support rod 113 to self-rotate under the action of the first bevel gear 119 and the second bevel gear 120 when the rotating shaft 112 rotates, so that the brake drum 103 rotates around the rotating shaft 112 and can also self-rotate on the support rod 113 under the action of the support rod 113, thereby putting the brake drum 103 in a rotating state and improving the shot blasting effect.

[0056] In actual use, in order to ensure that the brake drum 103 can rotate on the support rod 113, a plurality of convex strips are provided on the support rod 113, and under the action of the convex strips, the brake drum 103 can rotate on the support rod 113.

[0057] Furthermore, in actual use, a plurality of support rods 113 may be rotatably disposed on the housing 117 .

[0058] Furthermore, in actual use, the protection plate 109 is provided with a driving mechanism 121, and the driving mechanism 121 is used to drive the rotating shaft 112 to rotate, so that the rotating shaft 112 can achieve the purpose of uniform rotation.

[0059] Among them, the driving mechanism 121 includes a motor 122, a driving gear 123 and a driven gear 107. The motor 122 is installed on the protective plate 109, the driving gear 123 is connected to the motor 122, and the driven gear 107 is installed on the rotating shaft 112. The driving gear 123 and the driven gear 107 are meshed with each other, so that the rotating shaft 112 can be driven to rotate by the motor 122.

[0060] In addition, this embodiment also discloses a suspended shot blasting method, including using the above-mentioned suspended shot blasting machine to perform shot blasting operations on the brake drum 103.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
