Abstract
The invention provides a device for automatically removing black spots of a cam shaft. The device can high-efficiently solve the problem of black sports of a shaft neck of the cam shaft. The device comprises at least two clamp arms driven by a drive device so as to be closed and opened, wherein elastic flexible mechanisms are arranged on opposite faces of the clamp arms; a polishing compound is arranged on each elastic flexible mechanism. During a production process of the cam shaft, under the drive of the drive device, the elastic flexible mechanisms and the polishing compounds on end parts of the elastic flexible mechanisms are driven by the clamp arms so as to clamp the neck shaft or other parts of the cam shaft, so that when the cam shaft is rotated by a machine tool, the cam shaft can be automatically cleaned, and the black sports of the cam shaft are cleared. Due to the particular arrangement of the elastic flexible mechanisms, the influence of radial movement on the polishing compounds when the cam shaft is rotated can be eliminated, the polishing compounds are still fitted with the cam shaft, and the cleaning effect is ensured. According to the device, on the basis of existing resources and under the condition of lower cost input, the black sports of the cam shaft can be full-automatically cleared, and the device has excellent practicability.

Specifically, described elastic telescopic mechanism comprises body and lead, described body is installed on jig arm, described body is provided with guide through hole, one end of described lead is fixedly connected with poliss, the other end is through described guide through hole, and the position that described lead is exposed to guide through hole is provided with the anti-delinking part that diameter is greater than the guide through hole diameter; Described lead has spring at the cover of the position between poliss and body.Moving direction and the distance of poliss can be guaranteed in the anti-delinking part of lead and end thereof, and spring can will utilize its elastic force that poliss is compressed all the time and fits in the camshaft surface.
Further, described body and jig arm are provided with the slide rail of working in coordination, and described body is movably installed on jig arm by slide rail, and body can move with respect to jig arm, just can synchronously drive body when camshaft rotates like this and move along slide rail, guarantee that poliss fits with camshaft all the time.
Further, the both sides of described body are provided with back-moving spring, and an end and the body of described back-moving spring are connected and fixed, and the other end and jig arm are connected and fixed.Back-moving spring can apply reset force to body, impels body to move to leveling off to the position in camshaft axle center, to impel better poliss and camshaft laminating.
Further, the surface of described poliss is provided with arc-shaped depression portion, can not break away between assurance poliss and camshaft.
Further, the polishing hoof that described drive unit is the cam polishing machine, elastic telescopic mechanism can filter out the radial motion of polishing hoof, only retain the gyration of the relative camshaft of polishing hoof, therefore need not be transformed existing cam polishing machine, take full advantage of existing equipment, can reduce costs, and without extra equipment investment, therefore can not increase shared space, be very suitable for space and arrange compact production line.
Further, described poliss consists of installing plate and cellulosic piece, after using after a while, after wearing and tearing appear in the cellulosic piece, can change easily like this, and can not relate to the dismounting of other structure.
The device of automatic removal camshaft blackspot of the present invention is based on existing resource, in the situation that the cost input is lower, has realized full-automatic removing camshaft blackspot, has good practicality.
