Embodiment Construction

[0018] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0019] see image 3 and Figure 4 As shown, in this embodiment, a large-scale arc-shaped forging radial center reference marking tool includes a horizontal bar 1 and a vertical bar 2, and the horizontal bar 1 is provided with scales on both sides with its center as the zero point. The bottom end of the straight bar 2 is fixed on the center of the horizontal bar 1 by welding or riveting and is vertically arranged with the horizontal bar 1. Four sliding blocks 3 are installed on the horizontal bar 1. The horizontal rod 1 moves back and forth, and the four sliding blocks 3 are centered on the vertical rod 2. Two sliding blocks 3 are arranged on each side. The four sliding blocks 3 are all provided with threaded holes. The fixing screw 5 of the large arc forging 4, the length of the horizontal bar 1 i...

Abstract

The invention discloses a radial center benchmark lineation tool for a large arc-shaped forging. The radial center benchmark lineation tool comprises a horizontal rod and a vertical rod. The horizontal rod is provided with a scale. One end of the vertical rod is fixed to the center of the horizontal rod and is perpendicular to the horizontal rod, and four sliders are installed on the horizontal rod and can slide to and fro along the horizontal rod. According to the four sliders, the two sides with the vertical rod as the center are each provided with two sliders, and the four sliders are eachprovided with a fixing part for fixing the tool to the large arc-shaped forging overall. The length of the horizontal rod is larger than that of the large arc-shaped forging. The height of the vertical rod is larger than that of the large arc-shaped forging. The radial center benchmark lineation tool for the large arc-shaped forging is small and light overall, convenient to operate, good in universality and high in benchmark lineation precision.

Description

technical field [0001] The invention belongs to the large-scale arc forging processing technology, in particular to a large-scale arc forging radial center reference marking tool. Background technique [0002] In order to facilitate positioning during machining and reasonably allocate allowances, forgings are often marked with reference lines, which are usually measured with a height gauge or a vernier caliper. But for large curved forgings, see figure 1 and figure 2 as shown, figure 1 It is an end view of an existing large arc forging, figure 2 It is a side view of an existing large arc-shaped forging. Its height Z-direction and width Y-direction reference can make the forgings lie flat or stand upright in the width direction, and use a height ruler to mark the reference line. As for the center reference of the end face in the length X direction, due to the large forgings, it is inconvenient to stand vertically in the length direction, and it is impossible to use the ...
