Abstract
The utility model relates to a replaceable cutter blade drill bit for processing a maintaining bracket, which comprises a cutter handle (1) and a cutter blade (2), wherein the front end of the cutter handle (1) is provided with a clamp groove (4); the cutter blade is arranged in the clamp groove; the cutter handle on both sides of the clamp groove (4) are provided with thread holes; and a screw (3) for fixing the cutter blade is arranged in the thread holes. According to the size requirement, the cutter blade is processed into one size series in width from 50 mm at the increment of 5 mm. When a pocket hole of the maintaining bracket is processed, the cutter blade approximate to the size of the hole diameter is selected, sanded by a sand wheel, and then processed. The maintaining bracket with different pocket hole sizes can be processed by purchasing the cutter blade with different width, thereby saving the cost.
Description
Technical field
The utility model belongs to processing equipment, relates generally to a kind of changeable blade drill bit that is used to process retainer.
Background technology
Along with the adjustment of product structure, need the increasing extra large size bearing retainer of processing, the aperture is generally more than 60mm.The model difference needs the drill bit of different size.If the used drill bit of each model all goes to order goods, not only production cost is huge, and the delivery cycle is longer, directly influences manufacturing schedule.
Summary of the invention
The purpose of this utility model provides a kind of changeable blade drill bit that is used to process retainer, and it can change blade according to the difference of model, and is simple in structure, and it is convenient to change.
The purpose of this utility model can adopt following technical scheme to realize: it comprises handle of a knife, blade, is provided with draw-in groove at the front end of handle of a knife, and blade is arranged in the draw-in groove; The handle of a knife of draw-in groove both sides is provided with screwed hole, is provided for the screw of fixed blade in the screwed hole.
The utility model can be processed into a dimension series with blade by width according to dimensional requirement, from 50mm, increases progressively with 5mm.During processing retainer pocket hole, choose, can process through behind the grinder buffing near the blade of pore size.The retainer of the different pocket hole dimensions of processing only needs the blade of buying different in width to get final product like this, has saved production cost.
