Abstract
The utility model relates to a machining cutter bar guiding structure for a rotary machine tool. A mounting rack is placed on a workpiece. A machining cutter bar is arranged in through holes of the mounting rack via a shaft sleeve and a deep groove ball bearing. The deep groove ball bearing is axially positioned via a bearing cap and a snap ring. Through the effects of the shaft sleeve and the deep groove ball bearing together, a boring cutter bar is supported, and the deep groove ball bearing can withstand a certain radial force. During the hole machining process, the boring cutter bar is kept stable and is not subjected to radial play or axial swing, thereby guaranteeing the hole machining precision and increasing the hole machining quality.
Description
Technical field
The utility model relates to field of machine tool equipment, in particular for the rotary machine tool of processing large-diameter workpiece.
Background technology
Large-diameter workpiece such as hauling rope, coastal waters floating structure, radiotelescope and pressure vessel etc.; Need be at some guide pass of outer edge surface Surface Machining of structural I-beam; And the processing through hole, a hundreds of hole is arranged on the workpiece, and the hole requires to have certain machining accuracy; Because relevant at present special-purpose punch device, the method for machining hole all is first through the manual positioning and fixing of going mostly now, and then processes, and this method working strength is big, inefficiency.Perhaps be exactly to bore a hole in approximate location earlier, accomplish processing with boring cutter then.This processing method can satisfy the requirement of aspects such as precision for the through hole on the needs processing I-beam upper surface; During for the through hole of processing same position lower surface; Because it is very long that boring cutter bar needs; The reaction force that receives man-hour is very big adding, and boring cutter bar just has radial-play, and the precision in the hole that is processed just can not be guaranteed.
The utility model content
The applicant is big to above-mentioned existing associated orifices process equipment working strength; Shortcomings such as inefficiency and arbor stiffness are weak, machining accuracy can not be guaranteed; A kind of processing knife bar guide frame of rotary machine tool is provided; The high strength process requirements of processing work can be satisfied, and the machining accuracy in hole can be effectively improved.
The technical scheme that the utility model adopted is following:
A kind of processing knife bar guide frame of rotary machine tool, installing rack is positioned on the workpiece, and the processing knife bar is installed in through axle sleeve, deep groove ball bearing in the through hole of installing rack, and deep groove ball bearing carries out axial location through bearing cap and circlip.
The installing rack of the utility model is positioned on the lower surface in the processing of lower end face, at axle sleeve, under the actings in conjunction such as deep groove ball bearing, accomplishes the supporting to boring cutter bar, thereby guarantees the precision of hole processing; Deep groove ball bearing can bear certain radial load, in hole processing, with the mating reaction of installing rack under let boring cutter bar keep stable, radial-play does not take place, guarantee the quality of hole processing.The deep groove ball bearing outer ring contacts with plate hole inner headed face above the installing rack; Inner ring is placed on the axle sleeve; The deep groove ball bearing inner ring positions fixing through the outer peripheral face and the circlip for shaft of axle sleeve; An end face and the bearing air cover of outer ring through plate hole above the installing rack positions fixing, also can prevent radially wobbling of knife bar, thereby guarantee the precision of bore hole processing.
Description of drawings
Fig. 1 is the front view of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described.
As shown in the figure, the described boring cutter bar guide frame of the utility model comprises axle sleeve 1, bearing cap 2, deep groove ball bearing 3, installing rack 4, circlip for shaft 5.
In when work, installing rack 4 is positioned on the workpiece, and boring cutter bar 6 matches with axle sleeve 1 endoporus, and deep groove ball bearing 3 is fixed through bearing cap 2 by the internal face location of installing rack 4 top panel endoporus then, and bearing cap 2 is fixed on the installing rack through hexagon socket head cap screw.Deep groove ball bearing 3 outer peripheral face through axle sleeve on axle sleeve 1 cooperates, and carries out axial location through circlip for shaft 5 then.When boring cutter bar 6 rotates; Boring processing is carried out in the hole of 7 pairs of workpiece of boring cutter; Boring cutter bar rotates together with axle sleeve and deep groove ball bearing inner ring; Axle sleeve, deep groove ball bearing and installing rack prevent the boring cutter bar axial float and radially wobble the supporting role of boring cutter bar, thereby guaranteed the precision that bore hole is processed.
More than describing is the explanation to the utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of the utility model spirit, the utility model can be done any type of modification.
