Description
Technical Field
The utility model relates to a rocking arm curb plate bore hole chamfer gang tool belongs to loader technique and machining technical field.
Background
With the development of the machining industry, people pay more and more attention to the machining precision, particularly to engineering machining equipment. At present, when a shaft sleeve mounting hole in a rocker arm side plate is machined, a phi 205 through hole needs to be machined at the same position according to a workpiece drawing and process requirements, and finally the angle is chamfered by 12X45 degrees. In the past, two kinds of cutters are generally used in the manufacturing process and the machining process, a boring cutter is used for machining the through hole phi 205, and a chamfering cutter is used for machining a chamfer of 12X45 degrees. Because the processing needs to use two kinds of cutters of different models once, the processing of through-hole and drill way chamfer can only be accomplished to the arm on machining center changing the cutter twice, and the tool changing machining efficiency is low in succession, and the position precision of hole can not obtain guaranteeing, and product quality receives very big influence.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: when different apertures are processed at the same position on the side plate of the rocker arm, how to avoid using various cutters.
In order to solve the technical problem, the technical scheme of the utility model a rocking arm curb plate bore hole chamfer combined cutting tool is provided, a serial communication port, including the bore hole handle of a knife and install the cutter body on the bore hole handle of a knife, be equipped with bore hole blade installation department, chamfer blade installation department along the axial of bore hole handle of a knife on the cutter body in proper order, be fixed with the bore hole blade on the bore hole blade installation department, be fixed with the chamfer blade on the chamfer blade installation department.
Preferably, the boring blade and the chamfering blade are both provided with two and are symmetrically arranged along the rotation central axis of the cutter body.
Preferably, the distance between the boring blade and the rotating central shaft of the cutter body is the radius of a hole to be drilled on the side plate of the rocker arm; the distance between the chamfering blade and the rotating central shaft of the cutter body is the radius of the chamfer of the hole opening to be drilled on the rocker arm side plate.
Preferably, the boring blade is arranged at the upper end of the cutter body; the chamfering blade is arranged on the cutter body at a position far away from the head end; in the direction of the rotating central shaft of the cutter body, the distance from the head end of the boring blade to the tail end of the chamfering blade is the depth of a hole to be formed in the rocker arm side plate.
Preferably, the inclination of the chamfering blade on the cutter body is the inclination of an orifice chamfer to be drilled on the rocker arm side plate; the length of the chamfering blade is the length of the orifice chamfer.
Preferably, the boring blade and the chamfering blade are both mounted on the cutter body through fasteners.
Preferably, the fastener is a socket head cap screw.
The utility model provides a same aperture and chamfer need the technical problem of multiple cutter processing, the wide application is in machining. Compared with the prior art, the utility model discloses still have following beneficial effect:
because the boring blade and the chamfering blade are arranged on the cutter body, after the boring blade is used for processing a through hole, the chamfering blade directly processes a chamfer without replacing a cutter, the working efficiency is greatly improved, and the processing precision is ensured.
Because the boring blade and the chamfering blade are both provided with two blades which are arranged along the axis of the cutter body in a bilateral symmetry manner, the cutter has good balance and the service life of the cutter is prolonged.
Because the boring blade and the chamfering blade are both installed on the cutter body through the fasteners, after the blades are worn, only the blades need to be replaced, and therefore compared with the traditional scheme of replacing the cutter body, the boring blade and the chamfering blade are more convenient, more economical and more practical.

fig. 2 is a perspective view of a boring and chamfering compound tool for a rocker arm side plate.
Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
The utility model relates to a rocking arm curb plate bore hole chamfer combined tool, as shown in fig. 1, fig. 2 is shown, it includes bore hole handle of a knife 1 and installs cutter body 2 on the bore hole handle of a knife 1, be equipped with bore hole blade installation department along bore hole handle of a knife 1's axial in proper order on the cutter body 2, chamfer blade installation department, fixed mounting has bore hole blade 3 on the bore hole blade installation department, fixed mounting has chamfer blade 4 on the chamfer blade installation department, bore hole blade 3, chamfer blade 4 all is provided with two and follows cutter body 2's axis (be the center of rotation) symmetrical arrangement, bore hole blade 3, chamfer blade 4 all installs on cutter body 2 through the fastener. The fastener is preferably a socket head cap screw.
The distance between the boring blade 3 and the rotating central shaft of the cutter body 2 is the radius of a hole to be drilled on the side plate of the rocker arm; the distance between the chamfering blade 4 and the rotating central shaft of the cutter body 2 is the radius of an orifice chamfer to be drilled on the rocker arm side plate. The boring blade 3 is arranged at the upper end of the cutter body 2; the chamfering blade 4 is arranged on the cutter body 2 at a position far away from the head end; in the direction of the rotating central shaft of the cutter body 2, the distance from the head end of the boring blade 3 to the tail end of the chamfering blade 4 is the depth of a hole to be drilled on the side plate of the rocker arm. The inclination of the chamfering blade 4 on the cutter body 2 is the inclination of an orifice chamfer to be drilled on the rocker arm side plate; the length of the chamfer blade 4 is the length of the orifice chamfer.
Taking the machining of the rocker arm side plate through hole as an example, the boring blade 3 firstly machines a phi 205 through hole, and then the chamfering blade 4 machines a 12X 45-degree chamfer at the hole opening, so that the phi 205 through hole can be machined at the same position by one cutter, and simultaneously the 12X 45-degree chamfer at the phi 205 hole opening is machined, the cutter does not need to be replaced, the working efficiency is greatly improved, and the machining precision is ensured.
