Mounting equipment used for machining excavator big arm front fork holes

Abstract

The invention relates to mounting equipment used for machining excavator big arm front fork holes. The equipment comprises a bottom plate, a front end pressing mechanism, a middle fixing mechanism, apartition plate fixing mechanism, side plate fixing mechanisms and a lower portion jacking mechanism. The front end pressing mechanism is mounted at the front end of the upper surface of the bottom plate. The middle fixing mechanism is mounted in the middle of the upper surface of the bottom plate. The partition plate fixing mechanism is mounted in the middle-rear portion of the upper surface of the bottom plate. The side plate fixing mechanisms are arranged on the left and right sides of the upper surface of the bottom plate correspondingly, and the lower portion jacking mechanism is mountedon the upper surface of the bottom plate. The mounting equipment used for machining the excavator big arm front fork holes is reasonable in design, scientific in structure, high in practicability, high in rate of matching with workpieces and good in fastening effect, by using the equipment, the workpieces can be fast and accurately clamped and positioned, therefore, the machining precision and themachining quality are improved, and the workpiece dismounting, mounting and machining time is shortened.

Description

technical field [0001] The invention relates to the technical field of excavator production and processing, in particular to an installation device for processing the front fork hole of the large arm of the excavator. Background technique [0002] There is a front fork hole on the left and right sides of the front fork group of the boom arm of the excavator. After the front fork group of the boom arm of the excavator is assembled, there will be misalignment between the two front fork holes, so it needs to be adjusted Processing, the misalignment will be corrected, if not corrected, it will affect the subsequent processing. At present, when correcting, the relatively simple method is to place it on a boring machine for processing, but if image 3 As shown, the front fork group of the boom arm of the excavator has a special shape, irregular shape, and many arc surfaces. Therefore, the use of ordinary pressure plates not only has slow positioning and compression speed and low e...

Problems solved by technology

At present, when correcting, the relatively simple method is to place it on a boring machine for processing, but if image 3 As shown, the front fork group of the boom arm of the excavator has a special shape, irregular shape, and many arc surfaces. Therefore, the use of ordinary pressure plates not only has slow positioning and compression speed and low efficiency, but also has poor compression and fixing effects, and it is difficult to guarantee the processing quality.
