Abstract
The invention relates to a high-precision signal panel grinding device which mainly comprises a shaft sleeve, a casing and a chuck, wherein the casing is in a cylinder structure; one end of the casing is provided with the shaft sleeve; the shaft sleeve is provided with internal threads; the other end of the casing is processed into a flared conical covering surface, and the edge of the conical covering surface is provided with the sleeve-type chuck; three symmetrical points on the surface of the chuck are provided with a thin opening along the axial line of the casing; the inner wall of the chuck is provided with two inward asymmetric clamping grooves from the open end of the chuck; the inclination angle of the flared conical covering surface is 15-20 degrees; and the deviation angle of the two clamping grooves is 5 degrees. The invention has the advantages of ingenious structure, high efficiency, high stability, soft grinding, low labor intensity, high operating safety and the like, and is convenient to install and convenient to use.
Description
Technical field the present invention relates to process equipment, especially a kind of processing unit (plant) of auto parts and components.
Background technology is well-known, and the photo-electric crankshaft position sensor is arranged in the ignition distributor, and it is made up of the signal panels of signal generator and slotted unthreaded hole.Signal panels are installed on the distributor shaft, and main body is a disc-shaped structure, its outer slit that is with, periphery 6 unthreaded holes that distribute slightly in the inner part.When signal panels turn round with engine crankshaft, because of unthreaded hole is arranged on the signal panels, produce the alternate of printing opacity and shading, cause signal generator output to characterize crank position and the pulse signal of delivering.In sum, high for the processing request of signal panels, beating and can not surpass 0.1 in the surface, and under the unwarrantable situation of Sheet Metal Forming Technology, can only adopt peripheral milling to solve the problem of beating of endoporus and platter surface.But; Present milling tools generally adopts the supporting emery wheel of lathe to polish, and owing to lack the dedicated fixed grinding attachment that is directed to signal panels on the market, therefore can only adopt general cassette fixing means; In grinding process; Very easily cause signal panels distortion, depression or fracture, seriously influence operating efficiency, and waste a large amount of workpiece.
Summary of the invention the purpose of this invention is to provide high, stable strong, the soft high-precision signal mill turning device of grinding of a kind of efficient.
The present invention mainly comprises axle sleeve, sleeve pipe and dop, and sleeve pipe is a cylindrical structure, and an end is an axle sleeve, the axle sleeve machining internal thread; The sleeve pipe other end is processed into and extends out shape taper cover, and processes telescopic dop at taper cover edge; Offer thin mouthful in 3 positions of symmetry, dop surface along the casing axis direction; From the dop openend inwardly within it wall offer asymmetric two clamp bar slots.The gradient that extends out shape taper cover is 15～20 °.The drift rate of two clamp bar slots is 5 °.
Compared with present technology; Beneficial effect of the present invention is: delicate structure, easy for installation, easy-to-use, efficient is high, stability is strong, grinding is soft, labour intensity is low, handling safety; Outside dimension is stable, can be controlled in 0.02, and the axle center plane of symmetry is evenly stressed during the workpiece rotation.
Description of drawings Fig. 1 is a stereochemical structure sketch of the present invention.
Fig. 2 is mounting structure figure of the present invention.
The specific embodiment mainly comprises axle sleeve 1, sleeve pipe 2 and dop 3 in stereochemical structure sketch of the present invention shown in Figure 1, sleeve pipe is a cylindrical structure, and an end is an axle sleeve, the axle sleeve machining internal thread; The sleeve pipe other end is processed into and extends out shape taper cover, and processes telescopic dop 3 at taper cover edge; Offer thin mouthful 4 in 3 positions of symmetry, dop surface along the casing axis direction; From the dop openend inwardly within it wall offer asymmetric two clamp bar slots 5.The gradient that extends out shape taper cover is 15～20 °.The drift rate of two clamp bar slots is 5 °.
Add man-hour, adopt machined roll extrusion grinding way:
1, at the enterprising line operate of M1312 lathe; With axle sleeve insert in the bistrique and with bistrique in male thread be connected; Rotate through axle rotating band moving axis cover, sleeve pipe and dop in the bistrique; Two clamp bar slot sizes of dop inwall are to be that two bump sizes on Ф 27.75 circles design according to triggering wheel diameter, under dop, the indeformable situation of assurance housing little at active force, stir two convexities and are rotated like this.
2, adopt No. 2 rolling centers of Mohs, be contained in the tailstock of M1312 lathe, with Ф 90 take over a business to be contained on the tail spindle, the interference fits during fit-up gap, taking over a business the outer ring is the planar top of a wide 5mm, avoids triggering the wheel concave plane.
3, adopting 60# hardness is ZY2, brown corundum P300 * 127 * 40 emery wheels.
4, triggering 4 arrowbands 4.4 * 56 * 1.25 of wheel very easily is out of shape; The slight feed of grinding is to reach the purpose of roll extrusion grinding; Make and trigger wheel and in the roll extrusion grinding process, not only reached the purpose that grinding was proofreaied and correct but also reached in roll extrusion, in grinding, triggering wheel is fine motion, till static no-spark.
