Description
Technical field
Basis is practical newly relates to engine assembly field, particularly a kind of tool component of accurate installation crankshaft timing gear.
Background technology
The traditional assembly method of engine crankshaft timing gear is, timing points alignment tool is used to be placed on first and second trunnion and first connecting rod eck mould plan crankshaft axis, the timing target pointer of frock drops on above bent axle microcephaly axle journal, according to frock target pointer position, the timing draw-in groove of timing gears and frock timing target pointer aligned and installed to by timing gears on bent axle microcephaly axle journal, then beating (pressure) and put in place.
But when utilizing above-mentioned timing points alignment tool to install crankshaft timing gear, whether the target pointer of frock itself in use accurately, does not have cubing can to its demarcation of testing all the time.This frock, because of the available reference point of target inspection neither one, cannot use survey tool to identify it at control laboratory, is difficult to prove that the installation of crankshaft timing gear is accurate.That is, built-up crankshaft timing gears also exist inaccurate hidden danger of quality, but crankshaft timing gear assembles inaccurate meeting and causes engine to work or to occur great quality accident.
The information being disclosed in this background technology part is only intended to increase the understanding to this practical new general background, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
practical fresh content
This practical new object is the tool component providing a kind of accurate installation crankshaft timing gear, and supporting have frock cubing to identify the accuracy of the target pointer of frock, guarantees that crankshaft timing gear is accurately installed.
For achieving the above object, this practical tool component newly providing a kind of accurate installation crankshaft timing gear, comprising: alignment mechanism, and it is used for the center line of preliminary centering bent axle, the front end of this alignment mechanism is provided with timing pointer, and the center line of bent axle is indicated by timing pointer; And frock cubing, it is sleeve-shaped, it can be sleeved on microcephaly's axle journal of bent axle, this frock cubing comprises overcoat and positioning key, positioning key is located on the inwall of the outer end of overcoat, and positioning key mates with the keyway of bent axle, and the upper port of the inner of overcoat is provided with inspection breach, inspection breach overlaps with the center line of positioning key, by timing pointer whether with check breach to coincide to detect the center line whether timing pointer aims at bent axle.
Preferably, overcoat is net form cover.
Preferably, the consistent size of breach and timing pointer is checked.
Preferably, alignment mechanism comprises three groups of bows, and these three groups of bows are used for being connected on the first axle journal of bent axle, the second axle journal and the rod journal between the first axle journal and the second axle journal respectively.
Preferably, timing pointer is arranged on the center of forward bow.
Compared with prior art, originally practical newly have following beneficial effect: the tool component of the present embodiment is by arranging frock cubing, utilize and instead push away verification method, using the reference point of the keyway of bent axle as measuring system itself, the anti-correctness pushing away the timing pointer of checking tool component, eliminate the inaccurate hidden danger of tool component target, ensure that the assembly quality of engine.

Fig. 2 is the front view of frock cubing in the tool component according to this practical accurate installation crankshaft timing gear newly;
Fig. 3 is the sectional view of frock cubing in the tool component according to this practical accurate installation crankshaft timing gear newly.
Main Reference Numerals illustrates:
1-bent axle, 11-first axle journal, 12-second axle journal, 13-rod journal, 2-alignment mechanism, 22-timing pointer, 3-frock cubing, 31-overcoat, 32-positioning key.
Detailed description of the invention
Below in conjunction with accompanying drawing, this practical new detailed description of the invention is described in detail, but is to be understood that this practical new protection domain not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole description and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or part, and do not get rid of other element or other part.
As shown in Figure 1, according to the tool component of a kind of accurate installation crankshaft timing gear of this practical new detailed description of the invention, comprise alignment mechanism 2 and frock cubing 3, wherein alignment mechanism 2 is used for the center line of preliminary centering bent axle 1, the front end of this alignment mechanism 2 is provided with timing pointer 22, and the center line of bent axle 1 is indicated by timing pointer 22.In addition, frock cubing 3 is sleeve-shaped, it can be sleeved on microcephaly's axle journal of bent axle 1, in the present embodiment, this frock cubing 3 comprises overcoat 31 and positioning key 32, positioning key 32 is located at (see Fig. 2) on the inwall of the outer end of overcoat 31, this positioning key 32 mates with the keyway of bent axle 1, the upper port of the inner of overcoat 31 is provided with inspection breach 311, whether this inspection breach 311 overlaps with the center line of positioning key 32, coincide detect the center line whether timing pointer 22 aims at bent axle 1 by timing pointer 22 with inspection breach 311.
In such scheme, by arranging frock cubing 3, and the effect of positioning key 32 in this frock cubing 3 carries out detection and location to frock cubing, has uniqueness.Whether inspection breach 311 just comprises identical for detecting timing pointer 22, and identical then explanation timing pointer 22 just indicates the center line of bent axle, does not comprise identical as occurred, then prove that dress timing pointer 22 exists inaccurate fault.The tool component of the accurate installation crankshaft timing gear of the present embodiment is by detecting frock self, utilize reference point and anchor point that measuring system is set by the keyway of target bent axle), the anti-correctness pushing away the former measurement thing of checking (alignment mechanism 2), eliminate the inaccurate hidden danger of target of tool component, avoid the fault that engine crankshaft timing gear not timing causes.
As a kind of preferred embodiment, the overcoat 31 of frock cubing 3 is net form cover, and the effect of net form cover increases friction, convenient operation.
As a kind of preferred embodiment, the consistent size of inspection breach 311 and timing pointer 22.Testing accuracy is high.
As a kind of preferred embodiment, alignment mechanism 2 comprises three groups of bows 21, and these three groups of bows 21 are used for being connected on the first axle journal 11, second axle journal 12 of bent axle 1 and the rod journal 13 between the first axle journal 11 and the second axle journal 12 (see Fig. 1) respectively.By three groups of bows 21, centering is accurate.
As a kind of preferred embodiment, timing pointer 22 is arranged on the center of forward bow 21.
To sum up, the tool component of the present embodiment is by arranging frock cubing 3, utilize and instead push away verification method, using the reference point of the keyway of bent axle as measuring system itself, the anti-correctness pushing away the timing pointer 22 of checking tool component, eliminate the inaccurate hidden danger of tool component target, ensure that the assembly quality of engine.
The aforementioned description to this practical concrete exemplary is newly to illustrate and the object of illustration.These describe not wants newly to be defined as disclosed precise forms by originally practical, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain this practical new certain principles and practical application thereof, thus those skilled in the art can be realized and utilizes the practical new various different exemplary of basis and various different selection and change.This practical new scope is intended to limited by claims and equivalents thereof.
