Abstract
The utility model provides a gauge for a processing center main shaft inner hole. The gauge comprises a detection sleeve and a go-no go fixed gauge used together with the detection sleeve, wherein the front end of the detection sleeve extends into a main shaft inner hole; an outer edge is formed at the back end of the detection sleeve; the side wall of the detection sleeve is provided with a through hole; and a ball is arranged in the through hole. The gauge has the beneficial effects: the structure is simple, processing qualification of a processing center main shaft inner hole can be detected accurately and rapidly, and the processing accuracy of an inner hole of a central main shaft is increased.
Description
Technical field
The utility model relates to a kind of main shaft inner structure size cubing, relates in particular to a kind of machining center main shaft endoporus cubing.
Background technology
The machining center main axle unit is the key feature that realizes High-speed machining; The machining center main shaft is one of factor that influences main axle unit running accuracy, processing parts precision, security and main shaft most critical in serviceable life; Its inner structure size is the prerequisite that guarantees above-mentioned condition, whether qualified forge a knife stroke and the reliability that is having a strong impact on tool-broaching mechanism of its dimensioned.
Work in-process heart main shaft inner structure size all has corresponding cubing check like 7:24 taper hole, dish spring mating holes etc., like internal diameter scale or vernier caliper etc.But work in-process heart spindle taper hole (being the key position that the broaching tool pawl cooperates with main shaft) is BT30, JT30; BT40, CAT40; When BT50, CAT50, BT60, the grade of tolerance of size is generally G7 here, and its diameter is greater than 7:24 taper hole end diameter, and internal diameter scale or vernier caliper be energy measurement not all.
The utility model content
The purpose of the utility model be to provide a kind of simple in structure, can conveniently check the whether qualified machining center main shaft endoporus cubing of main shaft endoporus.
The utility model is realized through following measure: machining center main shaft endoporus cubing; Comprise check sleeve and the logical no-go gage that is used with said check sleeve; The front end of said check sleeve stretches into said main shaft endoporus; The rear end of said check sleeve is provided with the outer, and the sidewall of said check sleeve is provided with through hole, in the said through hole ball is installed.
The concrete characteristics of the utility model also have, and the outer retaining of said check sleeve is outside the port of said main shaft endoporus, and said logical no-go gage stretches in the said check sleeve.
The diameter of the diameter of said check sleeve and main shaft endoporus is complementary.
The standard size grade of tolerance of the specification of said logical no-go gage and main shaft endoporus is complementary.
The described machining center main shaft of the utility model endoporus cubing can produce and can verify accurately that accordingly spindle taper hole is BT30, JT30 according to the taper hole of main shaft different model; BT40, CAT40; The measurement cubing of the endoporus of the machining center main axle unit of specifications such as BT50, CAT50, BT60, it has solved the dimensional accuracy problem of check machining center main shaft endoporus.
The beneficial effect of the utility model is: simple in structure; Can check out the processing of machining center main shaft endoporus whether qualified quickly and accurately; Improved the machining precision of the endoporus of main shaft; And then solved the broach travel and the integrity problem of machining center main axle unit tool-broaching mechanism, and make the loose cutter of main axle unit and tool-broaching mechanism accomplish to put in place flexibly, broaching tool is reliable.During measurement, the check sleeve of the ball of will packing into stretches into the main shaft endoporus, puts in the check sleeve to the go side of logical no-go gage again, and the go side can be passed through; Put in the check sleeve to not-go-end again, not-go-end can not pass through, and can judge thus that then dimensioned is qualified here.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Wherein, Reference numeral is: 1, logical no-go gage; 2, ball; 3, main shaft; 4, check sleeve; 5, port; 6, outer.
Embodiment
For clearly demonstrating the technical characterstic of this programme, through embodiment, this programme is set forth below.
Referring to Fig. 1; The utility model is a kind of machining center main shaft endoporus cubing; Comprise check sleeve 4 and the logical no-go gage 1 that is used with check sleeve 4, the front end of check sleeve 4 stretches into the endoporus of main shaft 3, and the rear end of check sleeve 4 is provided with outer 6; The sidewall of check sleeve 4 is provided with through hole, and ball 2 is installed in the through hole; Outer 6 retainings of check sleeve 4 are outside the port 5 of the endoporus of main shaft 3, and logical no-go gage 1 stretches in the check sleeve 4.
During measurement, the check sleeve 4 of the ball 2 of will packing into stretches into the endoporus of main shaft 3, puts in check sleeve 4 to the go side of logical no-go gage 1 again, and the go side can be passed through; Put in check sleeve 4 to not-go-end again, not-go-end can not pass through, and can judge thus that then dimensioned is qualified here.
The utility model can pass through or adopt existing techniques in realizing without the technical characterictic of describing; Repeat no more at this; Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited in above-mentioned giving an example; Variation, remodeling, interpolation or replacement that those skilled in the art are made in the essential scope of the utility model also should belong to the protection domain of the utility model.
Claims (2)
1. machining center main shaft endoporus cubing; It is characterized in that; Comprise check sleeve and the logical no-go gage that is used with said check sleeve, the front end of said check sleeve stretches into said main shaft endoporus, and the rear end of said check sleeve is provided with the outer; The sidewall of said check sleeve is provided with through hole, in the said through hole ball is installed.
2. machining center main shaft endoporus cubing according to claim 1 is characterized in that, the outer retaining of said check sleeve is outside the port of said main shaft endoporus, and said logical no-go gage stretches in the said check sleeve.
