Description

A kind of monoblock type is to tooth pressing clamp

Technical field

This utility model is related to a kind of monoblock type to tooth pressing clamp, belongs to Gear Processing cubing technical field.

Background technology

At present, fowler welding axle be to be press-fited with idler gear Z36 by jackshaft Z15 to form, and require jackshaft Z15 and in Between gear Z36 tooth in have a tooth to have relative position relation, the tooth O of the tooth N in jackshaft Z15 and idler gear Z36, Position degree between them will reach 0.05.Therefore to ensure to weld the tooth of axle product to the position degree of tooth it is necessary to using to tooth Pressing clamp just can complete.Original fowler welding axle uses split-type design manufacture to tooth pressing clamp H59-1012 , former fixture is covered after processing and manufacturing respectively by upper tooth set and lower tooth, then connects into a dress by screw with terminal pad respectively Join entirety.Then adjust upper tooth set respectively, the mutual alignment relation of lower tooth set and terminal pad so that a tooth of upper tooth set with Symmetry between one tooth of tooth set reaches within 0.01, and does not have seam to position between upper tooth set and lower tooth set, adjustment Inconvenient and loaded down with trivial details, it is difficult to once just can mix up.Often adjust once and three coordinates after screw-driving, also will will be sent to go to examine it to tooth Symmetry（Require within 0.01）, as unqualified in symmetry just need to readjust tooth set, the phase between lower tooth set and terminal pad Mutually position, back and forth will be repeatedly.Be also difficult to ensure upper lower tooth set to just, 0.01, finally mixing up rear jig also needs to use completely Pin is killed, and prevents from loosening.With such method process to tooth pressing clamp, not only efficiency is low, and process product The symmetry of teeth portion is often overproof, technological requirement 0.05, and the product actually having has been even up to 0.3 ~ 0.5, and original fixture is such as Fig. 4.I.e. original fixture is split-type structural, including upper tooth set, terminal pad, lower tooth set and screw.

Content of the invention

The purpose of this utility model is to overcome drawbacks described above, provide that a kind of structure is simple, be easy to processing, easy to use and The monoblock type that need not assemble is to tooth pressing clamp.

The technical solution of the utility model：A kind of monoblock type is to tooth pressing clamp it is characterised in that described press-fits to tooth Fixture is overall structure, and this is integrally-built to include chuck body to tooth pressing clamp, and this chuck body is ⊥ shape overall structure, I.e. the top of integrally-built chuck body is the cylindrical structure with little internal tooth casing, and bottom is the disc structure with big internal tooth casing； Integrally-built chuck body is provided with upper tooth set position and the lower tooth set position of linear cutter formation, integrally-built fixture Body upper part cylinder is circumferentially with uniform observation port, and the effect of observation port is that the convenient position observing jackshaft Z15 tooth exists Load situation during pressing clamp, it can in addition contain play the effect mitigating weight；Upper tooth covers position and lower tooth covers the right of position Tooth precision is within 0.01.

This monoblock type mainly includes ⊥ clamp body to tooth pressing clamp, and upper tooth covers position, lower tooth set position and observation Hole, wherein go up tooth to cover position and lower tooth set position is that the method forming using wire cutting forms during clamped one time. Between upper tooth set position and lower tooth set position, there is at a relatively high positional precision, due to there are not assembling all parts, therefore, Just there is not rigging error, this monoblock type is higher than original clamp precision to tooth pressing clamp, and good stability.This monoblock type is to tooth Pressing clamp has been to ensure that the positional precision between upper and lower tooth set than the advantage of original fixture, easily stable can surely reach 0.01 Within.

This utility model is as the operation principle of original fixture.Simply design concept is different.Upper tooth in original fixture Set is two different parts from lower tooth set, and by upper tooth set, lower tooth set, the part such as terminal pad using screw and carries out assembling simultaneously Just can use after sending the position degree between a tooth of measuring room metering upper tooth set and a tooth of lower tooth set qualified, and this practicality New newly then need not assemble, less can be used with metering, because being formed using clamped one time linear cutter.

In sum, this utility model structure is simple, be easy to processing, easy to use and need not assemble parts, monoblock type High precision to tooth pressing clamp and good stability, the precision of welding axle product tooth pressing clamp being processed using this is steady Surely reach technological requirement.

Specific embodiment

Refering to above-mentioned accompanying drawing, a kind of monoblock type is to tooth pressing clamp it is characterised in that described is whole to tooth pressing clamp Body structure, this is integrally-built to include chuck body 01 to tooth pressing clamp, and this chuck body 01 is ⊥ shape overall structure, that is, whole The top of the chuck body 01 of body structure is the cylindrical structure with little internal tooth casing, and bottom is the disc structure with big internal tooth casing；Whole The chuck body 01 of body structure is provided with upper tooth set position 1 and the lower tooth set position 2 of linear cutter formation, integrally-built folder Tool body 01 top cylinder is circumferentially with uniform observation port 3；Upper tooth covers position 1 and lower tooth covers position 2 to tooth precision is Within 0.01.

The manufacture process to tooth pressing clamp for this monoblock type：Before this fixture manufactures, by ⊥ shape blank by drawing first, Good using lathe car, stay undressed at tooth set position 1 and lower tooth set position 2 two, fixture ⊥ shape blank integral quenching is reached To 50 ~ 55HRC.Then using ⊥ shape blank top down as locating surface, upward, fixation clamp pulls tight for ⊥ shape blank bottom Afterwards, once just upper tooth is covered position 1 using wire cutting to process with lower tooth set position 2 simultaneously.It is effectively guaranteed its fixture The symmetry precision of teeth portion is within 0.01.

To tooth pressing clamp on hydraulic press during converted productss, the position of wherein lower tooth set 2 is enclosed within center tooth to this monoblock type The position of wheel Z36, then the position of jackshaft Z15 is packed in the upper tooth set position 1 of fixture, it is pressed into hydraulic press, you can ensure The Z36 teeth portion of welding axle product and Z15 teeth portion symmetry are within 0.05, and process stabilization.

, to tooth pressing clamp, structure is comparatively simple for this monoblock type, monoblock type tooth pressing clamp is included chuck body 01, on Tooth covers position 1, lower tooth set position 2 and observation port 3, and wherein, upper tooth set position 1 and lower tooth cover position, and 2 is in clamped one time process The middle method forming using wire cutting forms.Upper tooth covers position 1 and lower tooth covers and has at a relatively high position essence between position 2 , due to there are not assembling all parts, therefore, just there is not rigging error, this monoblock type is to tooth pressing clamp than original in degree yet Clamp precision is high, and good stability.Than the advantage of original fixture, this monoblock type has been to ensure that upper and lower tooth covers it to tooth pressing clamp Between positional precision, can easily stable surely reach within 0.01.
