Description

Technical Field

[0001] This utility model relates to a workpiece surface treatment device, specifically a shot peening device. Background Technology

[0002] Shot peening is a process that uses high-speed impact to treat the surface of a workpiece. Through the impact and cutting action of abrasive on the workpiece surface, the surface of the workpiece can be cleaned and have different roughnesses, thereby improving the mechanical properties of the workpiece surface and quickly processing the surface of the workpiece.

[0003] This application addresses shot peening of workpieces in the nuclear industry, such as the shot peening of disassembled workpieces during nuclear power plant maintenance. Due to the unique working conditions in the nuclear industry, the surface of the workpieces to be treated may contain radioactive contaminants. Therefore, the potential harm to operators from radiation must be fully considered during the shot peening process. Consequently, a shot peening device adapted to the specific working conditions of the nuclear industry is needed. Summary of the Invention

It offers advantages such as ease of operation and high safety.

[0034] like Figures 1-3 As shown, in one specific embodiment, the feeding area 11 is located on the left side of the processing area. The processing chamber 12 is provided with shielding doors 14 on the left and right sides, and an operating hole and a viewing window are provided on the front side. The shielding door 14 on the left is used for the workpiece and the mounting platform 15 to enter and exit the processing chamber 12, and the shielding door 14 on the right is used for maintenance operations inside the processing chamber 12. The operating hole is sealed with protective gloves.

[0035] like Figure 4 and Figure 5 As shown, the frame is also equipped with a mounting platform 15 and a rotation drive assembly. The rotation drive assembly is used to drive the mounting platform 15 to rotate between the feeding area 11 and the processing area. The mounting platform 15 is used to carry the workpiece to be processed and, driven by the rotation drive assembly, automatically realizes the rotation movement between the feeding area 11 and the processing area.

[0036] like Figure 4 and Figure 5As shown, specifically, the frame is equipped with guide rails, and the mounting platform 15 is equipped with rollers. The mounting platform 15 is connected to the guide rails via the rollers. The indexing drive assembly includes a transmission belt 62 and an indexing drive component 61. The transmission belt 62 is sleeved on the frame and is arranged along the direction from the feeding area 11 to the processing area. The indexing drive component 61 is used to drive the transmission belt 62. The mounting platform 15 is connected to the transmission belt 62.

[0037] like Figure 4 and Figure 5 As shown, the mounting platform 15 further includes a base 151 and a tray 152. The tray 152 is rotatably connected to the base 151, and a chain is fixedly connected to the tray 152, the chain being arranged in a ring around the rotation center of the tray 152. The processing chamber 12 is also equipped with a rotary drive assembly 7, which includes a sprocket 71 and a rotary drive component. The rotary drive component drives the sprocket 71 to rotate.
