Above-mentioned tooth bar fine grinding clamping device, is characterized in that: described driven wheel is rotatably installed on described clamp body by bearing pin.
Above-mentioned tooth bar fine grinding clamping device, is characterized in that: described hold-down bolt lower end is provided with the presser feet for increasing lifting surface area.
Above-mentioned tooth bar fine grinding clamping device, is characterized in that: described base side wall is symmetrically arranged with at least two opening mounting grooves.
Above-mentioned tooth bar fine grinding clamping device, is characterized in that: described driving rack is fixedly mounted on described column by screw.
The utility model compared with prior art has the following advantages:
(1) use this tooth bar fine grinding clamping device manufacturing gear strip, tooth bar stable accuracy can be made to reach 5 grades (by GB10096-1988), and tooth bar machining accuracy is high.
(2) this tooth bar fine grinding is very reasonable with clamping device design, and simple and compact for structure, after clamping workpiece, operating personnel only need rotate driving handle and get final product complete operation, use very easy.
(3) this tooth bar fine grinding is simple with clamping device dismounting, is convenient to safeguard.
(4) this tooth bar fine grinding clamping device not only can process conventional tooth bar, and also can process various nonstandard tooth bar, the scope of application widely.
(5) production technology of this tooth bar fine grinding clamping device is simple, and a lot of parts are convenient to produce or buy all very much, and thus its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the utility model is described in further detail.
