Abstract
The utility model relates to the technical field of piston pin processing, in particular to a piston pin excircle chamfering roll processing device, which is characterized by comprising a piston pin locating mechanism, and upper and lower rolling wheels which are respectively located at the upper and lower sides of a piston pin and used for processing piston pin excircle chamfering, wherein the piston pin locating mechanism comprises a driving runner and a pair of driven runners, and the driving runner and the driven runners mutually cooperate to clamp the piston pin so as to locate the piston pin and drive the piston pin to rotate. The device has high processing precision, convenient operation and high processing efficiency.
Description
Technical field
The utility model relates to the piston pin processing technique field, the outer rounded corner roll processing device of particularly a kind of piston pin.
Background technology
Piston pin is the important connector of explosive motor cardiac component piston rod part.Piston, connecting rod and piston pin be combined with full floating and semi-floating, the guiding function of the outer rounded corner of piston pin directly influences assembly quality.The manufacturing of the most of employing of piston aluminium alloy, intensity of aluminum alloy is lower, and the quality of the outer rounded corner of piston pin may cause piston pin scratch piston pin hole when assembling.The outer rounded corner of piston pin has Dan Jiao, two angle and triangle, and domestic piston pin manufacturing enterprise all adopts the form of machinings such as car, mill to realize, the chamfer dimesion that these modes are processed, angle instability, and working (machining) efficiency is low.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of piston pin outer rounded corner roll processing device, and this installs not only machining accuracy height, and easy and simple to handle, the working (machining) efficiency height.
For achieving the above object, the technical solution of the utility model is: the outer rounded corner roll processing device of this piston pin, it is characterized in that: comprise the piston pin detent mechanism and lay respectively at the upper and lower rolling wheel that the upper and lower side of piston pin is used for the outer rounded corner of machining piston pin, described piston pin detent mechanism is made of an active runner and a pair of passive runner, described active runner and the passive runner clamping piston pin that cooperatively interacts is with the positioning piston pin and drive its rotation.
The beneficial effects of the utility model are the high accuracy processing that has realized the outer rounded corner of piston pin, the different various outer rounded corners that require of user have been satisfied, guarantee the shape of rounded corner outside the piston pin two ends, the uniformity of size, and help the operator and overcome artificial factor that steady quality is reliable.In addition, this plant automation degree height is operated simple and easyly, has improved working (machining) efficiency greatly, and the high accuracy of piston rod part is equipped with important and practical meanings, has wide market application prospect.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the partial structurtes schematic diagram of the utility model embodiment.
The specific embodiment
As depicted in figs. 1 and 2, the outer rounded corner roll processing device of piston pin of the present utility model, comprise the piston pin detent mechanism and lay respectively at the upper and lower rolling wheel 4 that piston pin 1 upper and lower side is used for the outer rounded corner of machining piston pin, described piston pin detent mechanism is made of an active runner 2 and a pair of passive runner 3, described active runner 2 and the passive runner 3 clamping piston pin that cooperatively interacts, thereby realized three-point fix to piston pin, pass through the rotation of driving gear 2 simultaneously, the rotation of driven plunger pin.
For piston pin is vertically located, the two ends up and down of above-mentioned active runner 2 are provided with radius and are a bit larger tham the initiatively back-up ring 7 of runner 2 radiuses.When active runner 2 and passive runner 3 clamping piston pins, the two ends up and down of piston pin will be blocked by back-up ring 7, thereby have realized the vertical location to piston pin.
Above-mentioned that is arranged on the travel(l)ing rest passive pinch roller 3, and in the present embodiment, this travel(l)ing rest is driven by oil cylinder 5, moves reciprocatingly with along continuous straight runs.
In the present embodiment, above-mentioned upper and lower rolling wheel 4 is respectively by upper and lower driving oil cylinder 6 control work, to do vertical reciprocating motion.
The utility model is outside piston pin during the rounded corner rolling and processing, support the positioning piston pin by a kind of detent mechanism of not being in the mood for of design voluntarily, and simultaneously the outer rounded corner of piston pin being carried out rolling and processing by upper and lower rolling wheel 4, rolling wheel can design according to the chamfer shape of customer requirements.Forms at 3 by active runner 2 and movable a pair of passive runner 3 and be not in the mood for detent mechanism piston pin is clamped, locatees, its clamping force is by the oil pressure adjusting of the oil cylinder 5 that is used to drive the zoetrope horizontal movement.Simultaneously, initiatively runner 2 rotates under driven by motor, drives the piston pin rotation.Then, under 6 effects of the driving oil cylinder behind the upper and lower rolling wheel 4, upper and lower rolling wheel 4 is pushed ahead and the clamping piston pin, and the outer rounded corner of piston pin cylindrical chamfer shape rolling and processing piston pin of customer requirements is pressed at the rolling wheel edge, and its roll extrusion power is regulated by the pressure that drives oil cylinder 6.
More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
