Abstract
The invention discloses a timing angle detecting device for a crankshaft assembly chain wheel, which comprises a dial gauge, a gauge rod, a vertical rod, a base, a tapered mandril, a V-shaped iron, keys and a limiting rack. The base is fixedly connected with the vertical rod and the gauge rod which are oppositely arranged in a left-right symmetrical manner, the dial gauge with an inward gauge head is horizontally arranged at the top end of the gauge rod, the top end surface of the vertical rod is located under the gauge head, and the height difference between the top end surface of the vertical rod and the gauge head is the semi-diameter value of the middle segment of the tapered mandril. Bearings at the two ends of a crankshaft are directly supported by the V-shaped iron, the front end surface of the V-shaped iron is fixedly connected with the limiting rack, and the V-shaped iron and the limiting rack are connected with the base by the keys. An elastic limiting structure consisting of a spring and a positioning sliding block is arranged in the limiting rack, and a roller needle for positioning the chain wheel is arranged at the side face of the top end of the positioning sliding block. The tapered mandril is squeezed into a connecting rod of a crankshaft assembly; when the connecting rod is horizontally swung at 180 DEG, two dial gauges calibrated at zero are used to respectively measure the deviation value of the tapered mandril and then the difference value measured by the two dial gauges is converted into an angle.
Description
Technical field
The present invention relates to a kind of pick-up unit that is used for component of machine, particularly detect the device of the positive hour angle of bent wheel assembly sprocket wheel.
Background technology
The petrolic crankshaft assembly chain wheel of miniwatt angle in correct time is an important quality index that influences the engine transmission performance.Prior art adopts " n " shape cubing comparative that replaces to detect, and this kind detection is a qualitative detection.Although prior art can be used in the production scene and detects, energy value does not show the actual deviation value, and its accuracy of detection is poor, can not reflect the product actual mass objectively, also is unfavorable for statistic of attribute and quality analysis certainly.
Summary of the invention
The present invention is primarily aimed at the deficiency of prior art, and it is simple relatively to propose a kind of structure, and it is convenient to detect, and directly shows the timing angle detecting device for crankshaft assembly chain wheel of measurement result.
The present invention realizes technical goal through following technical proposals.
Timing angle detecting device for crankshaft assembly chain wheel, it comprises dial gauge, table bar, montant, base, tapering plug, V shape iron, key and position-limited rack.Its improvements are: said base is a planar plate members; Left-right symmetric is fixedly connected the montant and table bar of two pairs of vertically-arrangeds; Table masthead end level is installed gauge outfit dial gauge inwardly; The montant top end face is the plane and is under the gauge outfit center line that both differences in height are tapering plug stage casing radius value, and the base middle part is provided with vertical rectangle open slot towards upper surface.Said V shape iron front end face is fixedly connected position-limited rack, and V shape iron and position-limited rack center bottom are provided with rectangular aperture groove down, and V shape iron and position-limited rack cooperate with base through key.The built-in positioning sliding block by spring and vertically-arranged of said position-limited rack is formed the elasticity position limiting structure, and side, positioning sliding block top is provided with needle roller and is stuck in the sprocket, and positioning sliding block is by screw lock.
Montant top end face in the said structure is the plane; This plane is the supporting of the equipped tapering plug of connecting rod; The montant height dimension that symmetry is installed in the base two ends is identical; The setting height(from bottom) of two dial gauges is measure-alike, and the gauge outfit center line of dial gauge is higher than montant top end face, and difference in height is the radius value in tapering plug stage casing.
The present invention compared with prior art has following good effect:
1, detection and localization is simple in structure, installation is convenient, the location is reliable;
2, under equal conditions change 180 ° of detection tapering plugs, quantize deviate through dial gauge, measurement result accurately, intuitively.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the schematic top plan view of Fig. 1;
Fig. 3 is the A-A section enlarged diagram of Fig. 1.
Embodiment
According to accompanying drawing the present invention is described further below.
Timing angle detecting device for crankshaft assembly chain wheel shown in the drawings, it comprises dial gauge 1, table bar 2, montant 3, base 4, tapering plug 5, V shape iron 6, key 7 and position-limited rack 8.Plane on the base 4 of rectangular flat shape; The right ends symmetry is fixedly connected the montant 3 and table bar 2 of two pairs of vertically-arrangeds; Table bar 2 top levels are installed gauge outfit dial gauge 1 inwardly, and montant 3 top end faces are the plane, and the equipped tapering plug 5 that detects usefulness of the connecting rod in the crank assemblby directly is bearing in this plane.The gauge outfit center line of dial gauge 1 is higher than montant 3 top end faces, and its difference equals the radius value in tapering plug 5 stage casings.Base 4 middle parts are provided with vertical rectangle open slot towards upper surface.V shape iron 6 is provided with rectangular aperture groove down with position-limited rack 8 center bottom, and V shape iron 6 cooperates with base 4 through key 7 with position-limited rack 8.Position-limited rack 8 built-in positioning sliding blocks 8.3 by spring 8.2 and vertically-arranged are formed the elasticity position limiting structure among the present invention.Said positioning sliding block 8.3 is by screw 8.4 lockings.During the actual use of the present invention, the bearing in the crank assemblby directly is bearing in the V shape iron 6, the position of adjustment positioning sliding block 8.3; Be stuck in sprocket wheel and crank center is in the collinear tooth until needle roller 8.1; With this location positioning bent axle, plug dress tapering plug 5 changes pendulum to the left side with connecting rod in tie rod holes; Make the montant 3 top plane contact in tapering plug 5 and left side, zero dial gauge 1 gauge outfit records the positional value of tapering plug 5 through the school in the left side.Connecting rod is changeed pendulum to the right side, and zero dial gauge 1 gauge outfit records the positional value of tapering plug 5 through the school by the right side equally, with about the numerical difference between of two dial gauges 1 be converted into the angular deviation value.The present invention quantizes deviate, and it is convenient, accurate to measure.
