Drawings
FIG. 1 is a schematic structural view of a guide sleeve for remanufacturing and repairing of a five-axis boring machine.
Detailed Description
In order to make the objects, contents and advantages of the present invention clearer, the following detailed description of the embodiments of the present invention will be made in conjunction with the accompanying drawings and examples.
Considering that the repair of the special cutter bar for introducing the clamp is difficult, the invention mainly aims at the remanufacturing repair of the inner hole of the guide sleeve of the bracket and meets the assembly clearance between the cutter bar and the guide sleeve. Through actual surveying and mapping of the support guide sleeve of the inlet fixture, the guide sleeve for remanufacturing and repairing of the five-axis boring machine is invented, and is shown in figure 1.
The guide sleeve comprises a columnar body 2, an inner hole 1 is formed in the center of the body 2, an annular flange ring 5 is arranged on the outer peripheral surface of one end of the body 2, an annular step 6 is formed between the annular flange ring 5 and the outer peripheral surface of the body 2, an annular groove serving as an oil storage tank 3 is formed in the outer peripheral surface of the middle of the body 2, and an oil hole 4 communicated with the inner hole 1 is formed in the oil storage tank 3 in the radial direction; the body 2 is matched with a bottom hole of a guide sleeve of the equipment clamp; after the body 2 is arranged in the bottom hole of the guide sleeve, the annular step 6 props against the end face of the bottom hole of the guide sleeve of the equipment clamp to play a role in limiting; the oil hole 4 is convenient for inject lubricating oil, and the oil storage tank 3 is used as a lubricating oil storage chamber, so that the lubrication of the cutter bar in the inner hole 1 is ensured.
One end of the inner hole 1 is provided with a chamfer which is positioned at the same end part of the body 2 with the annular step 6.
Based on the guide sleeve, the cutter bar and the guide sleeve are matched and precisely remanufactured and repaired in three steps:
firstly, when the coaxiality of the bottom hole of the guide sleeve of the clamp bracket meets the requirement, in order to reduce the fit clearance and improve the precision after assembly, the diameter size precision of the inner hole 1 of the guide sleeve is designed into two grades, namely the tolerance is 0.015 and 0.03, and the diameter size precision is selected according to the specific assembly condition;
secondly, when the coaxiality of the bottom hole of the guide sleeve of the clamp bracket can not meet the requirement, the diameter size of the inner hole 1 of the guide sleeve is determined to be phi 64.5+0.10, so that the guide sleeve hole can be finely bored to the matching size by adopting a machining center when the coaxiality of the bottom hole is not good.
Thirdly, the guide sleeve is pressed into a bottom hole of the guide sleeve of the clamp bracket, and the cutter bar is adopted to grind the inner hole 1 at a low rotating speed, so that a clearance of precise fit is finally achieved.
Practice proves that the remanufacturing and repairing of the imported five-axis boring machine stably improves the assembly quality of the bearing cover of the machine body, effectively solves the problem of tile hole dislocation during secondary assembly, avoids expensive acquisition cost of introduced equipment, and obtains remarkable military and economic benefits for equipment construction.
