Description

Technical Field

[0001] The utility model is applicable to the technical field of pipe fitting processing, and particularly relates to a pipe fitting cutting grinding device. Background Art

[0002] At present, after mechanical cutting, impurities such as heavy skin, burrs, bumps, shrinkage, slag, oxides, etc. will appear on the incision of pipe fittings. If the incision is not polished, it will affect the connection between the pipe fittings and easily scratch the workers. Therefore, after the pipe fittings are cut, the corresponding polishing mechanism will be used to polish and level the incision.

[0003] However, when grinding and leveling the cut of pipe fittings, the pipe fittings are often clamped and fixed from the ungrinded end of the outer side of the pipe fittings. This clamping method can only clamp the pipe fittings from a single end face, and cannot clamp and reinforce the pipe fittings as a whole, which can easily cause the pipe fittings to shake during the grinding process and affect the grinding quality. Therefore, we propose a pipe fitting cut grinding device. Utility Model Content

[0008] A servo motor is fixedly mounted on the outer surface of the hollow frame at one end away from the support plate, and the side of the servo motor transmission shaft is fixedly connected to the outer surface of the bidirectional screw rod through a coupling.

[0009] By adopting the above technical scheme, through the rotation transmission action of the bidirectional screw on the transmission sleeve, and the pushing conversion action of the push rod, the fitting arc plates are driven to synchronously move toward or relative to each other vertically inside the hollow tube, so that the fitting arc plates can fit the inner wall of the pipe fitting and perform a stop and limit treatment on it, and different positions inside the pipe fitting can be stopped and reinforced, further improving the stability of the pipe fitting during grinding and placement.

[0010] As an optional solution to the technical solution of the present application, a fixed frame is fixedly installed on the side of the hollow tube, a rotating motor is fixedly installed inside the fixed frame, a rotating rod is fixedly installed on the side of the rotating motor transmission shaft through a coupling, and the rotating rod is rotatably installed inside the hollow tube through a bearing, a fixed plate is fixedly installed on the top of the side of the support plate, an electric push rod is fixedly installed on the bottom surface of the fixed plate, and the bottom surface of the electric push rod transmission shaft and the top surface of the fixed frame are fixedly connected.

[0011] By adopting the above technical solution, the hollow frame and the pipe fitting can be driven to rotate by the driving action of the rotating motor to adjust the grinding position.

[0012] As an optional solution of the technical solution of the present application, a sliding groove is opened inside the middle end of the support plate, and the hollow tube is slidably installed inside the sliding groove.

[0013] By adopting the above technical solution, the vertical movement stability of the hollow tube and the hollow frame is ensured by the guiding sliding action of the sliding groove on the hollow tube.

[0015] By adopting the above technical solution, the horizontal position of the grinding drum can be adjusted by the driving action of the sliding guide rail.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1.
