Abstract

The invention relates to boring tool body nylon feather keys and belongs to the field of machining. At least a feather key at a load-bearing position and a feather key on one side of a boring tool are made of a nylon material. Due to the fact that the nylon feather keys are resistant to abrasion compared with wooden feather keys, lasting time of a guiding effect of the nylon feather keys is longer than that of the wooden feather keys in a process of boring a material hard to machine, guiding precision is high, and size precision and position precision of a machining steel pipe are guaranteed. Due to stable and reliable guiding precision of the nylon feather keys, cutting output in boring is larger than that of guiding of the wooden feather keys, boring times are reduced, and production efficiency is improved. In addition, repeating use rate of the nylon feather keys is higher than that of the wooden feather keys, the wooden feather keys are basically scrapped after finishing one time of boring, and although the nylon feather keys are abraded to some extent, the nylon feather keys can be still used in steel pipe series smaller than those machined last time till the nylon feather keys are scrapped.

Description

Boring cutter body nylon feather key
Technical field:
The present invention relates to a kind of boring cutter body nylon feather key, belong to field of machining.
Background technology:
In Boring, traditional processing method is to lead with wood key, this guidance mode can guarantee machining accuracy for the steel pipe in processing common material, short hole, but for the steel pipe of the difficult-to-machine materials such as P91, P92, deep hole, then is difficult to guarantee machining accuracy.Machining state with wood key guiding is: can play the effect of location, guiding at the starting stage of bore hole wood key, but in the wearing and tearing because of wood key of the stage of bore hole, and lost guide effect, finally make borehole dimensional accuracy, positional precision out-of-size.Under present processing conditions, in order to guarantee the machining accuracy in hole, usually take to reduce cutting output and the method that increases the bore hole number of times, take rapidoprint as P91, the deep hole pipe of P92 is example (aperture φ 500-φ 600, length 7-8 rice),
Need heavy boring two to three times, right boring just can be finished the bore hole operation two to three times, calculates the processing that needs just can finish in two days an arm from process time.This working (machining) efficiency can not satisfy need of production, and machining accuracy does not ensure reliably yet simultaneously.
Summary of the invention:
The object of the present invention is to provide a kind of wear-resistant, boring cutter body assembling that can guarantee the bore hole precision, improve working (machining) efficiency.
Technical solution:
The present invention includes feather key, the feather key of the feather key of boring cutter body load-bearing position and boring cutter one side adopts nylon material at least.
Described nylon material is nylon 66, its mechanical strength, rigidity, hardness, toughness height; Ageing-resistant performance is good; The machinery damping capacity is good; Wearability with good sliding, excellence; Machining property is good; When being used for accurate effectively control, without crawl, good, the good stability of the dimension of abrasion resistance.
The present invention compares with wooden feather key, the nylon feather key is along having continued the nonmetallic materials advantage lower than metal material hardness, can not scratch workpiece, simultaneously because the nylon feather key is more wear-resistant than wooden feather key, so its guide effect time more lasting than wooden feather key is longer, guiding accuracy is higher.
Take rapidoprint as P91, the deep hole pipe of P92 is example, only the feather key 2 with load-bearing feather key 2 and boring cutter one side replaces wooden feather key by the nylon feather key, only need heavy boring once, right boring once can finish the Boring operation of steel pipe, calculate from process time and can process three arms in two days.Compare with wooden feather key guiding, not only the precision of bore hole is high, and working (machining) efficiency has improved three times.
The repeat usage of nylon feather key is also high than wooden feather key in addition, wooden feather key is after finishing Boring, substantially just scrapped, although and the nylon feather key has wearing and tearing to a certain degree, but it can also continue on for the steel pipe series that size is slightly smaller than processing last time, by that analogy, until scrap.

Accompanying drawing 5 boring work state diagrams.
The specific embodiment:
The present invention includes boring cutter body 1, feather key 2, boring cutter 3, pinching screw 4, in the load-bearing position and the feather key 2 of boring cutter one side adopt nylon materials, all the other feather keys 2 adopt wood materials.
Nylon feather key 2 of the present invention adopts interference fit with the assembling mode of boring cutter body 1.
Take quadruple linkage boring cutter body as example, four nylon feather keys can be installed simultaneously, but in order to save cost, stressed the varying in size of feather key according to four positions in the working angles, the feather key 2 that can be two stressed large positions load-bearing feather key 2 and boring cutter one side adopts the nylon feather key, and the feather key of two other position gets final product with common wooden feather key 2.In the bore hole process, along with going deep into of bore hole, the deadweight of the cantilever problem of boring bar and boring bar and boring cutter body 1 can cause the sagging of boring cutter body 1, so that be positioned at feather key 2 stressed increases under the boring cutter body 1, thereby the speed that causes wearing and tearing is aggravated, so in the load-bearing position of boring cutter body 1 the nylon feather key is installed.Boring cutter 3 is in working angles, because the cutting force of cutter, can cause and cutter increases in the stressed degree of the feather key 2 of the same side, so also will be mounted to the nylon feather key at the feather key 2 with the position of cutter the same side.Relatively above-mentioned two feather keys of the feather key 2 of two other position, stressed less in working angles, the degree of wear is relatively low, so adopt wooden feather key.
For the boring cutter body of other bond number, in the stressed different principle of diverse location, in stressed large position the nylon feather key is installed according to feather key respectively, and other position installation normal wood feather key processed gets final product.
If all feather keys on the boring cutter body all use the nylon feather key, processing effect can be better.
