Processing device of rotational platform hole

Abstract

The invention discloses a processing device of a rotational platform hole, belonging to the technical field of machining. The processing device comprises a clamp body, a handle screw rod, a moving staff, a fixed staff, a compression screw, a changeable cutter rod sleeve and a changeable positioning pin; wherein the changeable positioning pin is fixedly arranged on the clamp body; one end of the handle screw rod is rotatably connected with the changeable cutter rod sleeve and the other end is rotatably arranged on the clamp body; the moving staff is fixedly arranged on the changeable cutter rod sleeve; and the fixed staff is fixedly arranged on the clamp body. The invention can regulate out a required pitch-row according to requirements and then carry out processing, wherein compared with the traditional fitter method of positioning by marking on hole sites, the pitch-rows of all holes are consistent in processing, thereby improving hole positional accuracy; meanwhile, the function of cutter guiding during processing is realized. The invention has the advantages of light weight, compact structure, and convenient operation, and can realize higher processing efficiency and better meet the technical requirements on processing holes on the rotational platform.

Description

technical field [0001] The invention relates to a device in the technical field of mechanical processing, in particular to a processing device for holes on a rotary platform with a diameter larger than 10,000 millimeters. Background technique [0002] Among the floating cranes installed in modern large-scale ship equipment, many floating cranes are installed on large-size slewing platforms, and large-size slewing platforms refer to their diameters greater than 10,000 mm. The power is transmitted through the cooperation between the pin shaft installed in the hole on the rotary platform and the roller. The position accuracy of the hole on the rotary platform directly affects the assembly with the roller. tolerance. In actual production, the machining process of the hole of the large-size rotary platform adopts the scribing method to determine the position, which is prone to deviation. After the machining is completed, the roller and the pin shaft cannot be matched, which seri...

Problems solved by technology

Analyzing the design of the device, it is not difficult to find the following disadvantages: a set of devices requires several drilling templates; different hole pitches need to manufacture different devices to meet the needs; circumferential holes with different diameters need to manufacture different devices to meet the needs; the actual During processing, it is necessary to continuously check the hole distance and replace the drilling template, which greatly affects the improvement of processing efficiency.

At present, there is no other relevant literature on the solution of large-size rotary table hole processing, and there is no report on the large-size rotary table hole processing device
