Embodiment Construction

[0030] The processing method of the taper pin hole of the clamp arm of the 450 ton manipulator of the present invention is used for processing such as figure 1 , figure 2 The tapered pin hole of the clamp arm of the 450-ton manipulator shown, the inner diameter of the large end of the tapered pin hole is φ180 (+0.04 / 0)mm, and the angle is 2.862°. The corresponding pin shaft of the tapered pin hole is as follows image 3 As shown, the outer diameter of the big end is φ180 (-0.014 / -0.054) mm, the height is 430 mm, and the weight of the pin shaft is more than 100 kg.

[0031] The present invention utilizes the taper inspection tool to realize the matching of the pin shaft and the taper pin hole to meet the matching requirements of the assembly taper, including the following steps:

[0032] The first step is to make a taper inspection tool;

[0033] Taper inspection tools such as Figure 4 As shown, the taper body 1 is included, and the taper body 1 is hollow. The taper surfac...

Abstract

The invention discloses a processing method for a tapered pin hole of a clamp arm of a 450-ton manipulator. A tapered degree checking tool is used for realizing the matching manufacturing of a pin shaft and the tapered pin hole, so as to meet a matching demand on the assembling tapered degree. The processing method comprises the following steps of: 1) manufacturing the tapered degree checking tool; simultaneously processing a check tapered surface of the tapered degree checking tool and the pin shaft corresponding to the clamp arm; and once grinding the check tapered surface of the tapered degree checking tool and the tapered surface of the pin shaft on a same grinding machine; and 2) utilizing the tapered degree checking tool to process the tapered pin hole of the clamp arm. According to the processing method, the tapered degree checking tool is utilized to transfer a check reference from a present tapered surface of the pin shaft to the tapered surface of the tapered degree checking tool, thereby meeting the matching demand on the tapered degree, avoiding the inconvenience brought by matching measurement performed by using the pin shaft, simplifying the manufacturing and detecting processes for the tapered pin hole of the clamp arm, and greatly increasing the processing efficiency. The invention also discloses the tapered degree checking tool.

Description

technical field [0001] The invention relates to a processing method of a large manipulator, in particular to a processing method of a taper pin hole of a clamp arm of a 450-ton manipulator. The invention also relates to a taper inspection tool used in the processing method. Background technique [0002] The manipulator is the supporting equipment of the forging equipment, which is mainly used to send the forging steel ingot to the forging table of the press, so as to realize the forging process. During the forging process, the manipulator can cooperate with the press to turn and move the blank to complete the shape required for forging. Therefore, to be precise, the manipulator is the supporting operator of the press. [0003] In recent years, with the development of the machinery industry, the demand for forging equipment is increasing, and the tonnage is increasing. Therefore, the size and tonnage of the supporting manipulator are also increasing, and the precision is ge...
