Abstract
The utility model discloses a kind of timing marks pick-up unit, belong to Machining Technology field.Comprise plastic plate, boss, screw and key, described key and boss press-fit and the endoporus on gear and keyway clearance fit, play the role of positioning, by containing timing marks, whether the tooth of the breach display on described plastic plate judges that whether gear timing mark angle is correct, reach detection of gear timing marks angle object.Compared with universal tool-measuring microscope, the utility model has the advantage of the environment no requirement (NR) to workshop, installation cost is low, detection time is short, efficiency is high, low to operator's skill set requirements.
Description
Technical field
The utility model relates to Machining Technology field, specifically, is a kind of timing marks pick-up unit.
Background technology
Pick-up unit in field of machining is generally universal tool-measuring microscope, and his shortcoming is high to environmental requirement, and detection efficiency is low, and detection time is long.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of timing marks pick-up unit.
The utility model relates to a kind of timing marks pick-up unit, it is characterized in that: comprise plastic plate, boss, screw and key.Described plastic plate is short cylindrical shape, and side is provided with a timing marks breach.Described screw is inserted fixing by the plastic plate center of circle.Described boss and key are fixed on the reverse side that plastic plate arranges screw, with the endoporus on gear and keyway clearance fit, play the role of positioning.By containing timing marks, whether the tooth of the breach display on described plastic plate judges that whether gear timing mark angle is correct, reach detection of gear timing marks angle object.
As further scheme of the present utility model, the width of described key and be highly less than gear keyway 0.5mm.
As further scheme of the present utility model, the diameter of described boss is less than bore 1mm.
As further scheme of the present utility model, the width of described timing marks breach and highly equal width and the height of gear two tooth.
Compared with prior art, good effect of the present utility model is:
The utility model has the advantage of the environment no requirement (NR) to workshop, installation cost be low, detection time is short, efficiency is high, low to operator's skill set requirements.
Accompanying drawing explanation
Fig. 1 is the utility model outside drawing;
Fig. 2 is gear under test outside drawing;
Fig. 3 is the schematic diagram that the utility model detects gear under test.
Mark in accompanying drawing 1,2,3 is respectively: 1. plastic plate; 2. boss; 3. key; 4. screw; 5. timing marks breach; 6. keyway; 7. timing marks.
Embodiment
The utility model provides a kind of timing marks pick-up unit, for making the purpose of this utility model, technical scheme and effect better clear, clear and definite, further describes the utility model referring to accompanying drawing.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and need not with restriction the utility model.
The utility model relates to a kind of timing marks pick-up unit, it is characterized in that: comprise plastic plate 1, boss 2, screw 4 and key 3.Described plastic plate 1 is in short cylindrical shape, and side is provided with a timing marks breach 5.Described screw 4 is inserted fixing by plastic plate 1 center of circle.Described boss 2 and key 3 are fixed on the reverse side that plastic plate 1 arranges screw 4, with the endoporus on gear and keyway clearance fit, play the role of positioning.By containing timing marks, whether the tooth of the breach display on described plastic plate 1 judges that whether gear timing mark angle is correct, reach detection of gear timing marks angle object.The width of described key 3 and be highly less than gear keyway 0.5mm.The diameter of described boss 2 is less than bore 1mm.The width of described timing marks breach 5 and highly equal width and the height of gear two tooth.
When pick-up unit puts into clearance fit in the middle of gear (corresponding key 3 and boss 2 are inside gear keyway and endoporus), two teeth of gear just expose to the open air on the breach of pick-up unit, and by whether two flank of tooth that identification breach shows have timing marks to judge, whether timing marks angle position is correct.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, therefore all changes be intended in the implication of the equivalency by dropping on claim and scope are included in the utility model, any Reference numeral in claim should be considered as the claim involved by limiting.
