Description
Technical field
The utility model relates to frock, especially, relates to a kind of drilling tool of thin-walled tube sheet.
Background technology
All the time; the boring of thin wall tube sheet is all a more thorny manufacturing procedure; mainly contain the factor of following several respects: thin wall tube sheet area is large, thickness is thin, poor rigidity, yielding, difficult clamping, difficult chip removal, easily shake cutter, easily hinder cutter; cause drilling quality to be difficult to ensure card, and the process-cycle is long.
For processing thin-walled class tube sheet in current industry, conventional has three kinds of clamping methods:
1, workpiece surrounding isometry block pad pressure appropriate, the some nylon blocks of middle pad, push down with some lengthening pressing plates more above, cutter is not shaken when ensureing boring, cutter and pressing plate, nylon block etc. can not have interference simultaneously, when this just requires to hole, nylon block and lengthening pressing plate need continuous transferring position, which gets into and will which be moved to.
This installation way merits and demerits is as follows:
Advantage: cost is low, easy to operate, middle-size and small-size thin-walled tube sheet is more applicable.
Shortcoming:
A, want not shake cutter, the quantity that middle spacer and pressing plate need can not be very few;
B, middle spacer and pressing plate need continuous transferring position, and operator can not general idea, otherwise likely can cutter and bored machine damage, and workpiece is scrapped;
The continuous transfer process of c, middle spacer and pressing plate must cause part deformation, as bore hole, may occur the situation of allowance deficiency;
D, medium-and-large-sized plate are not too applicable.
2, chock plate below whole workpiece, surrounding pressure is appropriate, and other operation is identical with the first clamping method.
This installation way merits and demerits is as follows:
Advantage: easy to operate, ultrathin tube sheet is more applicable.
Shortcoming:
A, cost are high, and cutting fluid brews for a long time and plank can be made deliquescing to become rotten, only will be able to renew for twice with 1;
One piece of iron plate can be produced when b, drill bit are about to drill part, point of a knife can head on this iron plate to be continued down to bore, iron plate can stick skidding on point of a knife and cause tool damage on the one hand, iron plate can embed in plank on the other hand, remove or change new plank if do not carry out, tremendous influence can be caused to the processing of next block plate;
C, require higher to drill bit, cutter life is uncontrollable, and sharpening holding time is too many, and aperture is also difficult to ensure.
3, special tooling is made, a nylon block is fixed every a segment distance outer-hexagonal screw in advance at T-shaped groove of working table place, prebored hole is accomplished fluently in Workpiece boring position, screw to punch tapping, then clamping workpiece processing, first the hole drill of those positions of prebored hole is before worn, then utilize the screwed hole in this some holes and frock that part is carried out strengthening and fix, with that can according to normal flow Drilling operation.
This installation way merits and demerits is as follows:
Advantage:
A, solve a shake cutter difficult problem, cutter life and crudy are ensured;
B, efficiency are high, process medium-and-large-sized thin-walled tube sheet in enormous quantities very applicable;
C, minimizing human intervention factor, error rate reduces greatly, and the labour intensity of operator also reduces.
Shortcoming:
A, versatility are not strong, and do a frock and can only process a kind of workpiece, frock just can not reuse once move;
B, for single-piece or small lot batch manufacture inapplicable;
The situation that on c, workpiece, hole is smaller is also inapplicable.
Utility model content
