Description

Technical Field

[0001] This utility model relates to the field of heat exchanger processing, and in particular to an automatic grinding device for heat exchanger tube sheets. Background Technology

[0002] A tube sheet burr remover is a device or tool used to remove burrs generated on tube sheets. Burrs often occur during the manufacturing process of tube sheets, which may be caused by cutting, welding or other processing. The presence of burrs may affect the sealing performance, safety performance or appearance quality of the tube sheet, so they need to be removed.

[0003] The prior art, disclosed in CN223000264U, describes a burr remover for tube sheets in petrochemical pressure vessels. This is primarily for the petrochemical industry, where tube sheets are commonly used to construct pressure vessels and heat exchangers. Currently, most tube sheets develop burrs around the boreholes during drilling, requiring a burr remover to remove them. However, most existing burr removers require deep penetration into the borehole to remove burrs within it, but burrs also accumulate on the edge of the borehole, making it difficult to remove burrs from that side. This results in poor burr removal efficiency and limited practicality. Therefore, to address these issues, a burr remover for tube sheets in petrochemical pressure vessels is proposed.

[0004] Existing tube sheet deburring devices are slow, complex in structure, and unsuitable for automated operation, affecting the accuracy and efficiency of the processed products. Therefore, a new solution is urgently needed to optimize processing efficiency. Utility Model Content

The automatic control frame structure includes a horizontal moving control seat connected to the main connecting seat and a synchronous control frame structure provided on both sides of the horizontal moving control seat.

[0007] The aforementioned grinding and deburring device includes an upper connector, a socket body connected to the upper connector, a connecting shaft body located at the lower part of the socket body, a burr grinding surface located outside the connecting shaft body, and an end locking end located at the lower end of the socket body.

The beneficial effects of this utility model are as follows: This utility model, through a synchronous multi-station deburring mechanism, can perform multi-station processing operations at once. During use, the automatic control frame structure drives the tube sheet hole drilling and grinding structure to move in multiple directions on the working surface to process tube sheets of different thicknesses. It has a faster and more efficient deburring effect.
