Abstract
The invention relates to a sector gear positioning/drilling tool fixture which is characterized by comprising a positioning bottom plate, wherein a pressure plate for clamping a sector gear is arranged on the positioning bottom plate; two positioning pins are respectively arranged on the left and right of the positioning bottom plate; a reference hole is arranged between the two positioning pins and located on the center line of the horizontal distance between the two positioning pins; the two positioning pins are located on the circumference of a circle; and the circle is concentric with the sector gear. The positioning pins are located on a reference circle of the sector gear and matched with tooth slots on the outer circumference of the sector gear. The number of teeth between one positioning pin and the center line is equal to that between the other positioning pin and the center line. The pressure plate is fixed on the positioning bottom plate through a fastening screw arranged in the middle of the pressure plate; and the lower end of the pressure plate is provided with an adjusting screw. The sector gear positioning/drilling tool fixture provided by the invention can effectively and reliably fix workpieces and improve the stability of processing quality, effectively eliminates potential hazard in manual clamping, realizes convenient clamping and improves the working efficiency.
Description
Technical field
The present invention relates to a kind of positioning tool that is used for sector gear, especially a kind of sector gear location drilling frock clamp belongs to field of machining and machinebuilding technology.
Background technology
Need to use sector gear in the textile machine, i.e. a bit of in whole circle gear.This section sector gear needs to come location and installation with pin-and-hole in use.And there is the position relation at the pin-and-hole at this place and a tooth center.Whole circle tooth base is processed in general employing earlier in the middle of the prior art, carries out draw-bore earlier, and again by the gear hobbing processing of pin-and-hole location, gear hobbing processing this moment need make a tooth center overlap with a pin-and-hole center by moving cutter or rotary work-table carries out tool setting.Such mode processed complex, processing has a big risk, qualification rate is very low, and the back pin-and-hole can occur cutting off because distortion and the overproof phenomenon of position degree.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of sector gear location drilling frock clamp is provided, the processing risk is low, accepted product percentage is high.
According to technical scheme provided by the invention, described sector gear location drilling frock clamp, feature is: comprise positioning plate, positioning plate is provided with the pressing plate that is used to clamp sector gear, two location pins of left and right setting are arranged on described positioning plate, be provided with datum hole between two location pins, described datum hole is positioned on the center line of two location pin horizontal ranges, described two location pins are positioned on the circumference of a circle, and should be the circle concentric with sector gear by circle.
Described location pin is positioned on the reference circle of sector gear.
Described location pin cooperates with teeth groove on the sector gear excircle.
Described two location pins equate with the number of teeth between the center line.
Described pressing plate is fixed on the positioning plate by the trip bolt that is arranged on the pressing plate middle part, is provided with adjustment screw in the lower end of pressing plate.
The present invention has the following advantages:
(1) adopt this covering device can be effectively, fixation workpiece reliably, improve the stability of crudy greatly;
(2) adopt this covering device can effectively eliminate artificial clamping hidden danger;
(3) adopt this covering device clamping facility, increase work efficiency greatly;
(4) this covering device scope of application is wider, fricton-tight friction, and the life-span is longer;
(5) this covering device is simple in structure, and manufacturing cost is lower.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with concrete accompanying drawing.
As Fig. 1～shown in Figure 2: sector gear location drilling frock clamp comprises positioning plate 1, pressing plate 2, trip bolt 3, adjustment screw 4, location pin 5, sector gear 6, datum hole 7 etc.
The present invention includes positioning plate 1, positioning plate 1 is provided with the pressing plate 2 that is used to clamp sector gear 6, described pressing plate 2 is fixed on the positioning plate 1 by the trip bolt 3 that is arranged on pressing plate 2 middle parts, be provided with adjustment screw 4 in the lower end of pressing plate 2, be used to regulate the distance of 1 of pressing plate 2 other ends and positioning plate, thereby sector gear 6 is pressed abd fixed on the positioning plate 1; Two location pins 5 that left and right setting is arranged on described positioning plate 1, between two location pins 5, be provided with datum hole 7, described datum hole 7 is positioned on the center line AA ' of two location pin 5 horizontal ranges, described two location pins 5 are positioned on the circumference of a circle, and should circle for the circle concentric, as the reference circle of this sector gear 6 with sector gear 6;
Described location pin 5 cooperates with teeth groove on sector gear 6 excircles;
Described two location pins 5 equate with the number of teeth between the center line AA '.
Operation principle of the present invention: whole circle tooth base carries out gear hobbing processing earlier, cuts off operation afterwards, allows the distortion of workpiece (sector gear 6) discharge fully.Work in-process is the present invention in the heart, workpiece utilizes the teeth groove location by two location pins 5, datum hole 7 centers on the centering positioning plate 1, pressing plate 2 is by adjustment screw 4 and trip bolt 3 workpiece pressings, because datum hole 7 centers of design overlap with the center line AA ' of workpiece, so the pin-and-hole center that gets out in datum hole 7 centers also overlaps with the center line AA ' of workpiece.Because workpiece cuts off, distortion discharges fully, so the overproof risk of pin-and-hole position degree that can not occur getting out.The present invention be by the diameter of location pin 5 reasonable in design, reasonably realize at the center of datum hole 7 on the positioning plate 1, simple in structure, but be skillfully constructed.
