Abstract
The utility model discloses a boring fixture for processing a positioning pin hole of a timing gear. The boring fixture comprises a ring flange and is characterized in that the lower part of a positioning mandrel is connected with the central part close to the ring flange in a matching way and is limited by a rotation resisting pin; a support seat is matched with a positioning pin arranged at the edge part close to the ring flange and is connected onto the ring flange in a positioning way through screws; a positioning screw penetrates through the support seat along the radial direction of the ring flange; and the end part of the positioning screw points to the positioning mandrel. According to the boring fixture disclosed by the utility model, the positioning pin hole subjected to thermal treatment in the end surface of the timing gear can be processed, so that the precision of the hole pitch between the positioning pin hole and an inner hole of the timing gear can be improved and the requirement on the precision of an included angle between a connecting line of the center of the positioning pin hole and the center of the inner hole of the timing gear and a connecting line of the center of the inner hole of the timing gear and the center of a pitch circle tooth socket can be met; the boring fixture can bore on a general lathe and is reliable in positioning and convenient to clamp; and in addition, the production efficiency is increased and the cost is reduced.
Description
Technical field
The utility model relates to the machining frock, is specifically related to a kind of boring jig that is used to process the timing gears dowel hole.
Background technology
Timing gears are installed in the front end of engine cam, and with camshaft before the end-journal interference fit.The end face of timing gears is provided with dowel hole; The line at the center of this dowel hole and timing gears endoporus center; And an angle a (positive hour angle) is arranged between the line at timing gears endoporus center and pitch circle teeth groove center, and this dowel hole is suitable with the alignment pin on the frock pressure head that is used to press-fit timing gears.The relative installation of engine crankshaft and camshaft is to be confirmed by the position of engagement of timing gears, directly influences port timing.Therefore, this dowel hole not only and the pitch-row required precision between the endoporus on the timing gears very high, and said angle a also had higher requirement, reach ± 2 °.This timing gears structure is special; Cause the distortion of dowel hole and tooth portion and pin-and-hole self very big after the heat treatment; Must to correct time gear face pin-and-hole reprocess since this part heat treatment after hardness very high, can't process with universal cutter; So design this boring jig, process with the boron carbide cutter at engine lathe.
Summary of the invention
The purpose of the utility model provides a kind of boring jig that is used to process the timing gears dowel hole; These anchor clamps are processed the dowel hole on the timing gears end face after can processing heat treatment; The pitch-row precision of dowel hole and timing gears endoporus can be improved, the required precision of positive hour angle (being the angle between the line at line and timing gears endoporus center and pitch circle teeth groove center at center and timing gears endoporus center of dowel hole) can be guaranteed again.
The described a kind of boring jig that is used to process the timing gears dowel hole of the utility model comprises ring flange, it is characterized in that: the bottom of a location axle is connected with the centre near ring flange, and spacing through stop pin; One supporting seat cooperates with the alignment pin that is located near on the ring flange edge, and is located by connecting on the ring flange through screw; One location screw points to apotting spindle along radially pass said supporting seat and the end of ring flange.
Described a kind of boring jig that is used to process the timing gears dowel hole, the top of its said apotting spindle cooperates with the endoporus of timing gears, the end of said dog screw and the teeth groove of timing gears near.
The utility model is compared with prior art and is had the following advantages:
1) can process the dowel hole on the processing timing gears end face after the heat treatment; The pitch-row precision of dowel hole and timing gears endoporus can be improved, the required precision of the angle a between the line at line and timing gears endoporus center and pitch circle teeth groove center at center and timing gears endoporus center of dowel hole can be reached again;
2) on engine lathe, process, reduced cost with this frock;
3) in machined into, the location is reliable, convenient mounting and clamping, and process time is short, has improved production efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of boring jig that is used to process the timing gears dowel hole referring to illustrated in figures 1 and 2 comprises ring flange 5, and its design feature is: the bottom of a location axle 1 is connected with the centre near ring flange 5, and spacing through stop pin 6; One supporting seat 3 cooperates with the alignment pin 8 that is located near on ring flange 5 edges, and is located by connecting on the ring flange 5 through screw 7; One location screw 4 points to apotting spindle 1 along said supporting seat 3 of radially passing of ring flange 5 and end.
Carry out bore hole and add man-hour, the endoporus of needs being processed the timing gears 9 of dowel hole 10 cooperates with the top of apotting spindle 1, with locking nut 2 locking, and make dog screw 4 end and timing gears teeth groove near; Then, will along ring flange 5 clampings on engine lathe, can carry out bore hole processing.Adopt the utility model processing timing gears dowel hole; The pitch-row precision of dowel hole and timing gears endoporus can be improved, the required precision of the angle a between the line at line and timing gears endoporus center and pitch circle teeth groove center at the center that reaches a pin-and-hole and timing gears endoporus center can be protected again.
