Have detect awl Huo of the function gets a design

Awl Huo gets the taper seat inside the introduction (namely conic aperture) treatment difficulty is great, because of its existence detects, the difficulty such as platoon bits and refrigeration, the element that decides the hardest is the feed of knife head, the experience that it wants to rely on a worker and adjust ability to finish repeatedly, reason quality stability is poorer, and treatment efficiency is very low. Normally method is: With treatment of numerical control machine tool, of cone detect use taper plug guage to besmear lubricious law will detect. Because the spot produces equipment to differ and spare parts appearance each different, with color of besmear of taper plug guage the law detects often be restricted, if the graph shows a part 1 times, on general accuracy machine tool the round taper hole to deep aperture spare parts is machined, use taper plug guage to besmear lubricious law will detect at present its cone angle and dimension precision cannot come true. This design basically offers a kind to collect is machined and detect the device at an organic whole -- awl Huo is gotten (see a picture 2) , can machine the round cone angle of the spare parts not only, and after treatment is finished but synchronism undertakes detecting the cone angle of conic aperture, dimension, form tolerancepublic errand and exterior surface roughness are worth etc. 2.

The whole that design technology program designs originally is tectonic: Main by arbor 1, fixed position is sold 2, spacing piece 3 the head that reach a knife 4 composition. Fixed position sells 2 installation to be in arbor 1 (the knife handle part of 1 is arbor Mohs awl handle, use 45 carbon steeliness to become, cooperate reliable and accurate, assemble and unassemble fast) on, with arbor 1 be filled with too cooperate H7/s6, its center line and arbor center line become 90 ° , sell in order to avoid fixed position 2 fly off and make sure location of spare parts treatment is exact; Spacing piece 3 use common carbon steel, installation is in arbor 1 on, with arbor H7/g6 of 1 clearance fit, can be in arbor 1 go up to slide freely, rose to machine intention of spare parts position; Knife head 4 secure in arbor 1 right end, solder for what high-speed steel or hard alloy and carbolic steel comprise body, assuming the cutting job that awl Huo gets. Prior operation deep aperture kind of the spare parts inside when taper seat, in the installation on general accuracy machine tool this awl Huo is gotten, load knife handle lathe, installation is inside the tailstock aperture of the machine tool, and drilling machine is installation is inside main shaft aperture. Become when cutting face of 3 lower ends comes up against spacing piece when face of deep hole bottom, spacing piece 3 namely to main shaft feed opposite way moves, spacing piece comes up against fixed position to sell 2 when, spacing piece 4 suspend campaign, the job of mental allowance of cone of purify spare parts stops accordingly namely. Should go up end panel comes up against fixed position to sell 2 when, fixed position is sold 2 restricted spacing piece jointly with face of deep hole bottom the motion of 3, right now because of spacing piece the action of 4, knife head cannot continue to go ahead to, reason decided taper hole is the largest exclusively mouth diameter D, synchronous also the treatment that solved this taper hole and detect, obtained a part thereby inside the design requirement of taper seat angle and dimension. Pursue 1 it is one is machined the prior operation part drawing of the spare parts, blueprint appearance asks to assure inside conic horn α is in 0 ° ～ inside 180 ° limits all but, diametical D ± 0.

1mm and diametical D2 ± 0.

1mm, at the same time internally taper seat offerred taller form tolerancepublic errand and exterior quality requirement. Want to assure to design a requirement, traditional treatment method is: Need orders the boring tool that place of numerical control machine tool requires and design tool, ability can assure to machine. Of the taper seat inside besides detect, it is to use design taper plug guage to detect normally. But the graph shows a spare parts 1 times to be deep aperture spare parts, cannot detect with taper plug guage. 3.

This design settled technical good point inside problem of taper seat difficult treatment, also solved at the same time detect problem. It and existing technology photograph compare have the following advantage: (1) the structure is simple, the design is original. Its clever in working process affiliation orgnaization of link stopper fixed position, make workpiece locates automatically in the implementation in machining a process and synchronism detects, reduced factitious factor, make quality stabler. (2) bulk is cabinet, weight is light, the operation is convenient. Petiole uses commonly used Mohs awl power, cooperate reliable and accurate, the operation is convenient. In whole unit process of cargo bandling, the worker needs both hands to be able to undertake assembling and unassemble only, need not multifarious swing and assemble and unassemble. (3) detect precision is taller. Can detect dimension precision public errand comes 0.

2mm, special apply to the treatment that controls the taper seat inside the dimension, deep aperture spare parts that cannot detect hard. (4) make simple, manufacturing cost is low, facilitating promotion is used. Knife handle and knife head use different data, material of cutter hub cutting part uses commonly used high-speed steel or hard alloy material is qualitative, quench hardness 60 ～ 64HRC; Auxiliary part uses 45 carbon steel to pledge via tone processing can come true, reduced cost greatly, facilitating promotion is used.
