Abstract
The utility model relates to a fan-shaped gear positioning and drilling tool fixture which is characterized by comprising a positioning bottom plate; pressing plates for clamping a fan-shaped gear are arranged on the positioning bottom plate; two positioning pins arranged at the left side and the right side are arranged on the positioning plate; a reference hole is arranged between the two positioning pins and is positioned in a center line of the two positioning pins on the horizontal distance; the two positioning pins are positioned on the circumference of a circle; and the circle is concentric with the fan-shaped gear. The positioning pins are positioned on a divided circle of the fan-shaped gear. The positioning pins are meshed with tooth grooves in the outer circumference of the fan-shaped gear. The number of teeth between the two positioning pins and the center line is equal. The pressing plates are fixedly arranged on the positioning bottom plate by fastening screws arranged at the middle parts of the pressing plates; and adjusting screws are arranged at the lower end of the pressing plate. The fan-shaped gear positioning and drilling tool fixture has the beneficial effects that a workpiece can be effectively and reliably fixed, and the stability of the processing quality can be improved; the human clamping hidden troubles are effectively eliminated; the clamping is convenient, and the work efficiency is improved.
Description
Technical field
The utility model relates to a kind of positioning tool that is used for sector gear, and especially a kind of sector gear location drilling frock clamp belongs to field of machining and machinebuilding technology.
Background technology
Need use sector gear in the textile machine, i.e. a bit of in whole circle gear.This section sector gear need 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 through 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 through 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 purpose of the utility model is to overcome the deficiency that exists in the prior art, and a kind of sector gear location drilling frock clamp is provided, and the processing risk is low, accepted product percentage is high.
The technical scheme that provides according to the utility model; Said sector gear location drilling frock clamp; Characteristic is: comprise positioning plate, positioning plate is provided with the pressing plate that is used to clamp sector gear, and two location pins of left and right setting are arranged on said positioning plate; Between two location pins, be provided with datum hole; Said datum hole is positioned on the center line of two location pin horizontal ranges, and said two location pins are positioned on the circumference of a circle, and should be the circle concentric with sector gear by circle.
Said location pin is positioned on the reference circle of sector gear.
Said location pin cooperates with teeth groove on the sector gear excircle.
Said two location pins equate with the number of teeth between the center line.
Said pressing plate is fixed on the positioning plate through 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 utlity model has following advantage:
(1) adopt this covering device can be effectively, the reliable fixation workpiece, improve the stability of crudy greatly;
(2) adopt this covering device can effectively eliminate artificial clamping hidden danger;
(3) adopt this covering device clamping convenient, 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 the structural representation of the utility model.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with concrete accompanying drawing the utility model is described further.
Like 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 utility model comprises positioning plate 1; Positioning plate 1 is provided with the pressing plate 2 that is used to clamp sector gear 6; Said pressing plate 2 is fixed on the positioning plate 1 through 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 said positioning plate 1; Between two location pins 5, be provided with datum hole 7; Said datum hole 7 is positioned on the center line AA ' of two location pin 5 horizontal ranges; Said two location pins 5 are positioned on the circumference of a circle, and should circle for the circle concentric, like the reference circle of this sector gear 6 with sector gear 6;
Said location pin 5 cooperates with teeth groove on sector gear 6 excircles;
Said two location pins 5 equate with the number of teeth between the center line AA '.
The operation principle of the utility model: whole circle tooth base carries out gear hobbing processing earlier, cuts off operation afterwards, lets the distortion of workpiece (sector gear 6) discharge fully.Work in-process is the utility model in the heart; Workpiece utilizes the teeth groove location through two location pins 5; Datum hole 7 centers on the centering positioning plate 1; Pressing plate 2 is through adjustment screw 4 and trip bolt 3 workpiece pressings, owing to datum hole 7 centers of designing 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 utility model is to realize through the center of datum hole 7 on the diameter of location pin 5 reasonable in design, the rational positioning plate 1, and is simple in structure, but is skillfully constructed.
