Abstract
The utility model relates to a spot-facing cutter, which mainly comprises a guide post (1), a cutting edge (2), a drill bit toolbar (3) and a guide sleeve (4). The guide sleeve (4) is fastened on the guide post (1) through welding, so as to protect surface quality of a machined hole from damage during machining and meanwhile ensure machining position precision. The spot-facing cutter can meet the demand of a manufacturer for spot-facing work with position requirement, has the characteristics of simple structure, convenience in fabrication and stable machining performance, and can ensure precision and meet machining requirements.
Description
Technical field
The utility model relates to a kind of improved spot-facing cutter, and relating in particular to a kind of is the counterbit of pilot hole with machining hole.
Background technology
Spot-facing processing is scraped planar end surface to the hole that has processed on the workpiece exactly or is cut out the method for taper, cylindrical pit, is exactly the structure that typically needs spot-facing as cylindrical pit above the bolt hole in decelerator, the shaft coupling, and routine is to adopt counterbit to process.
For some the cylindrical pit of position degree requirement is arranged, the axis that requires to machine cylindrical pit in back and bolt hole can not have skew, and conventional at present processing method is to adopt the counterbit (as shown in Figure 1) with lead.Its lead diameter is complementary with diameter of bolt hole.
But, in the spirality cutting edge of making counterbit, owing to there is the withdrawing process, inevitably will on the surface of lead, leave the spirality escape, in the processing of leading, certainly will cause bolt hole inner surface damage like this, cause product quality not meet the demands, phenomenons such as yield rate is low, product and waste of material.
The utility model content:
The purpose of this utility model is that will to provide a kind of be pilot hole with machining hole, can not damage the counterbit of bolt hole inner surface in the process.
To achieve these goals, the technical solution of the utility model is: a kind of improved spot-facing cutter, mainly form by fairlead, lead, cutting edge, drill bit knife bar, fairlead is by welding, be connected on the lead, the effect of fairlead is not damage the surface quality of machining hole in the process, guarantees the Working position precision simultaneously.
The utility model can satisfy manufacturing enterprise to the spot-facing processing needs of position degree requirement are arranged, have simultaneously simple in structure, be convenient to make, processing characteristics is stablized, guarantee precision, satisfy the characteristics of processing request.
Description of drawings
Fig. 1 is cylindrical pit and the present common counterbit that needs processing.
Fig. 2 is the installation diagram of a kind of spot-facing cutter of the utility model.
Among the figure, 1-lead 2-cutting edge 3-drill bit knife bar 4-fairlead
The specific embodiment
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete cutter that the utility model proposes.
A kind of spot-facing cutter of the utility model.Be made up of lead 1, cutting edge 2, drill bit knife bar 3, fairlead 4, fairlead 4 is fastened on the lead 1 by welding, and the effect of fairlead 4 is not damage the surface quality of machining hole in the process, guarantees the Working position precision simultaneously.
Claims (1)
1. a spot-facing cutter mainly is made up of lead (1), cutting edge (2), drill bit knife bar (3), fairlead (4), it is characterized in that: fairlead (4) is fastened on the lead (1) by welding.
