The working principle is as follows: when the pipe fitting elbow sand casting adopted by the invention is used for manufacturing a surface finishing processing device, firstly, according to the structure of the pipe fitting, a first pipe fitting fixing frame 17 is selected to be arranged on the round hole 3 on one side of the sliding groove 22, then according to the structure of the pipe fitting, the working position of the sliding seat 19 on the bottom supporting plate 1 is adjusted, and the position of a second pipe fitting fixing frame 24 on the arc-shaped supporting plate 23 is adjusted, so that the first pipe fitting fixing frame 17 and the second pipe fitting fixing frame 24 can clamp and fix two ends of the pipe fitting; then, one end of the pipe elbow is fixed on the first pipe fixing frame 17 in the step S1 through the clamping device 18, the other end of the pipe elbow is fixed on the second pipe fixing frame 24 in the step S2 through the clamping device 18, then the pipe with the two ends clamped and fixed is polished, the burr of the connecting lines on the two sides of the pipe is polished and removed on the outer wall of the pipe through the polishing rollers 16 on the two sides, the surface of the pipe is smooth, finally, the pipe with the burrs removed is disassembled, the two ends of the pipe are loosened through the clamping device 18, the pipe is disassembled from the top end of the workbench, and the fine finishing treatment on the sand casting manufacturing surface of the pipe elbow is completed.
In addition, the working principle of the grinding roller of the invention is as follows:
Through having two spacing wheel branch 1502 at axostylus axostyle 1505 both ends of the roller of polishing 16 articulated respectively, spacing wheel 1501 is installed on the top of two spacing wheel branch 1502 of the every one end of the roller of polishing 16, when polishing, two spacing wheels 1501 of every one end contact with the both sides outer wall of pipe fitting joint line burr, it is spacing to the degree of depth of the roller of polishing 16 with pipe fitting surface contact through spacing wheel 1501, it is too deep to avoid the roller of polishing 16 to receive the elastic support pole promotion and pipe fitting surface contact, lead to the volume of polishing too much.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
