Abstract
The invention discloses a centerless grinding machine which comprises a machine base, an automatic loading and unloading device, a control cabinet, a guide wheel and a guide wheel dressing mechanism. The guide wheel dressing mechanism comprises a dresser main body and a moving mechanism arranged on the dresser main body. The moving mechanism comprises a first lead screw, a gear and a second lead screw, wherein the first lead screw is transversely movably connected onto the dresser main body, and the second lead screw is vertically arranged on the dresser main body and is movably connected with the dresser main body. The gear is arranged on the dresser main body and is meshed with the first lead screw and the second lead screw respectively. The centerless grinding machine achieves adjustment of the guide wheel in the horizontal direction and the vertical direction through matching of the lead screws and the gear, is convenient to use, and improves accuracy and stability of a dresser.
Description
Technical field
The present invention relates to a kind of grinding machine, particularly a kind of processing valve stem centerless grinder belongs to technical field of machining.
Background technology
The grinding of valve stem is to produce one of valve critical process, in centerless grinder process in the past, because the particularity of valve processing, need arc transition, on the basis of conventional hydraulic, can only walk gauge finder, so the requirement on machining accuracy to gauge finder is very high, is difficult to satisfy its processing request.
Chinese patent literature discloses a kind of trimmer, and the patent No. is called " centerless grinder guide wheel trimmer " for " 201210541447.0 " name, and this trimmer comprises trimmer main body, horizontal mobile mechanism and reciprocating mechanism; Described horizontal mobile mechanism comprises slide mass, slide block screw and moves horizontally screw mandrel; Move horizontally screw mandrel by moving horizontally the handle drive, drive the slide block screw and move horizontally under the driving that moves horizontally screw mandrel, the slide block screw is fixed on the slide mass by shank of screw and drives the slide mass horizontal movement; Described reciprocating mechanism comprises: move up and down screw mandrel and move up and down handle; Move up and down screw mandrel and be fixed on the trimmer main body by being equipped with cap and spanner, move up and down the gathering sill of screw mandrel on the slide mass of slide block control lower edge and move up and down, move up and down the screw mandrel top and move up and down handle by bolting; Move up and down the screw mandrel bottom and be connected with golden pen by set bolt, the making of this centerless grinder guide wheel trimmer is simple in structure, but the product that has special angle or complicated shape transition for design then can not carry out copying, and machining accuracy is lower.
Summary of the invention
Technical problem to be solved by this invention provides a kind of centerless grinder, position finishing step, circular arc and other special shape that this grinding machine can in officely be what is the need for and be wanted, thereby, improved the quality of product greatly.
In order to solve the problems of the technologies described above, a kind of centerless grinder of the present invention, comprise support, automatic loading and unloading device, switch board, guide wheel and guide wheel burring machine, wherein, described guide wheel burring machine comprises the trimmer main body, is arranged on the travel mechanism on the described trimmer main body, wherein, described travel mechanism comprises first screw mandrel, gear and second screw mandrel, and described first screw mandrel laterally is movably connected on the described trimmer main body, described second screw mandrel is vertically set on the described trimmer main body, and is connected with described trimmer subject activity; Described gear is arranged on the described trimmer main body, and described gear is meshed with described first, second screw mandrel respectively.
Above-mentioned centerless grinder, wherein, the cross section of described gear is S shape.
Beneficial effect of the present invention:
The present invention by leading screw and cooperating of gear realizing guide wheel level and the adjusting of vertical direction, use conveniently, improved precision and the stability of trimmer; In addition, because the cross section of gear is S shape, can realize the interpolation interlock of trimmer, thereby, the quality of product improved greatly.
