Embodiment Construction

[0019] The present invention will be further described below in conjunction with the embodiments in the accompanying drawings.

[0020] Such as figure 1 and figure 2 The shown precision grinding device for the inner surface of a steel pipe includes a traveling mechanism 1 , a throwing rod 2 , a driving mechanism for the throwing rod 2 and a damping mechanism 3 . The traveling mechanism 1 includes a track 11 and a trolley 12. The lower end of the trolley 12 is provided with a traveling wheel 121 rolling along the track 11, and the trolley 12 is provided with a traveling drive motor 13 for driving the traveling wheel 121 to rotate. There are two rails 11 parallel to each other, and four road wheels 121 are symmetrically distributed on the rails 11 . The trolley 12 is provided with a mounting frame 4, the mounting frame 4 is provided with a fixture 41 for fixing the throwing rod 2, a driven wheel 42 positioned at the end of the throwing rod 2, and a main motor 43 for driving t...

Abstract

The invention provides a precise grinding device for the inner surface of a steel tube. The device comprises a walking mechanism, a throw rod, a throw rod driving mechanism and a shock absorbing mechanism, wherein the walking mechanism comprises a track and a trolley, walking wheels rolling along the track are arranged at the lower end of the trolley, and a walking driving motor which drives the walking wheels to rotate is arranged on the trolley; a mounting rack is arranged on the trolley, a clamp for fixing the throw rod, a driven wheel located on the end part of the throw rod and a main motor which drives the driven wheel to rotate are arranged on the mounting rack, and the throw rod is arranged parallel to the track. The device can process two steel tubes simultaneously and is compactin structure and good in processing stability and uniformity, and the inner walls of the steel tubes are not damaged.

Description

technical field [0001] The invention relates to the technical field of steel pipe processing, in particular to a precision grinding device for the inner surface of a steel pipe. Background technique [0002] For the finished tube that is cold processed by the metal section forming machine (rolling mill) or drawing machine, but because the inner surface roughness of the tube blank does not meet the product quality requirements, especially for products with high precision requirements, it needs to be polished by the inner surface To meet product characteristics. The current grinding device can only process one steel pipe at most, and the stability and uniformity are difficult to guarantee, and it is easy to cause damage to the inner wall of the steel pipe, and even cause uneven wall thickness of the steel pipe. Contents of the invention [0003] The invention provides a precision grinding device for the inner surface of a steel pipe. The device can process two steel pipes a...
