Description

Technical Field

[0001] This utility model relates to grinding equipment, specifically to a grinding equipment for removing residual sand from the inner wall of pipe castings. Background Technology

[0002] During the casting manufacturing process, due to the characteristics of its forming process, excess structures such as risers and flash will inevitably appear on the surface of the casting. Simultaneously, the sand core inside the casting is prone to adhering to the casting body under high-temperature casting conditions, forming residual sand that is difficult to remove. This is especially challenging for castings with specific hole sizes and depths, where cleaning residual sand inside the pipes presents a significant challenge. Conventional cleaning methods are insufficient to achieve ideal removal results, becoming one of the key factors affecting casting quality.

[0003] Currently, existing technologies for cleaning castings mostly employ a mode of using multiple machines individually, that is, using different machines to clean residual sand inside the pipe and external burrs separately. This cleaning method has many limitations: on the one hand, it requires a wide variety of equipment, leading to a significant increase in initial equipment investment costs; on the other hand, during the cleaning process, the castings need to be transferred multiple times between different machines, which not only prolongs the production cycle but also increases the risk of damage to the castings during transportation. Utility Model Content

[0004] The purpose of this invention is to solve the technical problem of transferring and cleaning castings between multiple devices during the cleaning process, and to provide a device for removing residual sand and grinding the inner wall of pipe castings.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A device for removing residual sand and grinding the inner wall of a pipe casting includes a box with a feeding port, a dual-station turntable at the feeding port of the box, and a grinding robot inside the box.

[0007] The box body is provided with a clamping bracket located at the loading port. The clamping bracket is provided with a clamping cylinder. The output shaft of the clamping cylinder is provided with a clamping block. The clamping block is placed above the station of the dual-station turntable located outside the box body. The clamping block and the station of the dual-station turntable located outside the box body cooperate to fix the tubular workpiece.

[0008] One side of the clamping bracket is provided with a tubular workpiece inner wall cleaning mechanism, and the cleaning shaft of the tubular workpiece inner wall cleaning mechanism can extend into the tubular workpiece.

[0009] Furthermore, the workpiece inner wall cleaning mechanism includes a base, a feed slide rail on the top of the base, a transverse adjustment slide rail on the top of the slide table of the feed slide rail that is perpendicular to the sliding direction of the feed slide rail, a vertical adjustment slide rail on the slide table of the transverse adjustment slide rail, and a power head on the slide table of the vertical adjustment slide rail.

[0010] The output end of the power head is equipped with a sweeping shaft via a chuck.

[0011] Furthermore, the cleaning shaft includes a shaft body, and multiple interlaced steel wire strands are provided on the outer side wall of the shaft body.

[0012] Furthermore, the shaft body is provided with a plurality of staggered through holes, and the steel wire strands are placed in the through holes;

[0013] A clamping screw is installed on the outer wall of the shaft, and the end of the clamping screw extends into the through hole and abuts against the steel wire strand.

[0014] Furthermore, a screw is provided at the end of the shaft away from the chuck, and a wire wheel is sleeved on the screw, and the wire wheel is fixed to the end of the shaft by a clamping nut.

[0015] Furthermore, a protective plate is provided on the side of the clamping bracket opposite to the inner wall cleaning mechanism of the tubular workpiece;

[0016] A protective light grid is provided on the side of the clamping bracket opposite to the dual-station turntable.

[0017] Furthermore, a protective cover is provided on the top of the base.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The utility model provides a device for removing residual sand and grinding the inner wall of pipe castings. It combines a grinding robot with a cleaning mechanism for the inner wall of tubular workpieces, so that the device can both grind burrs and flash on the outer surface of the tubular workpiece and clean residual sand on the inner wall of the tubular workpiece. Both processes can be completed with a single loading. Compared with existing equipment, it does not require multiple devices, reducing the initial equipment investment cost. Moreover, by setting up a dual-station turntable and a clamping cylinder used in conjunction with the dual-station turntable, there is no need for intermediate transfer links when switching processes, avoiding the risk of damage to the castings during transfer.
