The fixture comprises a supporting seat and is characterized in that the fixture additionally comprises a drill plate, wherein a limiting flange which is matched with the gear is arranged on one surface of the drill plate, a plurality of holes which correspond to inclined surface holes to be drilled are formed in the drill plate, a drill bush is installed in each hole, a plurality of groups of pressing mechanisms which are used for pressing the drill plate are arranged close to the drill plate, and the pressing mechanisms are connected with supporting seat. The fixture for hole drilling on the inclined surface of the gear has the advantages that the structure is simple, the fixture is convenient to use, the clamping stability is high, the machining accuracy is high and the service life of drill bits can be prolonged.

Description

Gear inclined-plane boring grab
Technical field
The utility model belongs to the clamping tool for machine work technical field, particularly relates to a kind of gear inclined-plane boring grab.
Background technology
Along with manufacturing development, division of labor specialization, large-scale mass production, product parts lightness, powder metallurgy maturing, high-quality a large amount production capacity power have become the inexorable trend of development, requirement to part processing and manufacturing fixture used is also more and more higher, and fixture is the important frock that guarantees Workpiece Machining Accuracy and production efficiency.At present, the card of some gears is the inclined-plane on the market, require the processing circular hole on the inclined-plane, processing method in conventional art is: utilize hold-down mechanism that gear is pressed abd fixed on supporting seat, utilize drill bit directly to hole on the inclined-plane of gear, when adopting as above simple fixture to carry out Drilling operation to the inclined-plane of gear, inclined-plane on gear can make drill slipping, borehole accuracy is difficult to guarantee, and easily damages drill bit, the service life of shortening drill bit.
Summary of the invention
The utility model be intended to solve the gear inclined-plane Drilling operation low precision that exists in known technology, bit grinding loss rate high-technology problem and provide a kind of simple in structure, easy to use, be installed stable, machining accuracy is high, and can extend the gear inclined-plane boring grab of drilling life of bit.
The utility model for the technical scheme that solves the technical problem that exists in known technology and take is: a kind of gear inclined-plane boring grab, comprise supporting seat, it is characterized in that: also comprise bushing plate, has the defining flange that coordinates with gear on the one side of bushing plate, described bushing plate is provided with several holes corresponding with beveled aperture to be processed position on gear, in described each hole, drill bushing is installed all, be provided with the some groups of hold-down mechanisms that are used for compressing bushing plate near described bushing plate, described hold-down mechanism is connected with described supporting seat.
The utility model can also adopt following technical scheme:
Described hold-down mechanism comprise the bolt that is connected with described supporting seat, with bolted pressing plate and the support column that is positioned at described pressing plate one side.
Described bushing plate is provided with locating hole, in described locating hole, alignment pin is installed.
Be provided with two groups of hold-down mechanisms that are used for compressing bushing plate near described bushing plate, described two groups of hold-down mechanisms are symmetrically set in the both sides of described bushing plate.
Described pressing plate is provided with the elongated slot that coordinates with described bolt.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme; namely design a kind of novel auxiliary clamp of holing of being used on the inclined-plane of gear; this fixture comprises drill bushing; drill bushing can effectively protect drill bit non-slip in the process of boring the inclined-plane; both effectively improved borehole accuracy; arranged the service life that can extend drill bit, and in addition, that the utility model also has advantages of is simple in structure, easy to use, mount is stable.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
In figure: 1, supporting seat; 2, bushing plate; 2-1, defining flange; 2-2, locating hole; 3, gear; 4, drill bushing; 5, alignment pin; 6, bolt; 7, pressing plate; 8, support column; 9, nut.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
See also Fig. 1 and Fig. 2, a kind of gear inclined-plane boring grab comprises supporting seat 1 and bushing plate 2, has defining flange 2-1 on the one side of bushing plate 2, defining flange 2-1 can coordinate with the circular trough on 3 of gears, limits with the radial position that makes 2 pairs of gears 3 of bushing plate.Bushing plate 2 is provided with several holes, drill bushing 4 is installed in each hole, and the design in hole need to be corresponding with the hole on the inclined-plane of gear 3 to be processed, in the present embodiment, center take bushing plate 2 on bushing plate 2 is evenly equipped with four holes as the center of circle, four Kong Zhongjun are equipped with drill bushing 4.Be provided with hold-down mechanism near bushing plate 2, hold-down mechanism is connected with supporting seat 1, with for gear to be processed 3 is pressed between bushing plate 2 and supporting seat 1.
Gear 3 is cast member, generally be cast with the symbol and the numeral that represent manufacturer or some other identity on cast member, during gear 3 boring, hole on the inclined-plane of General Requirements assurance gear 3 and symbol or numeral align, to guarantee the overall appearance of product, described, be provided with locating hole 2-2 on bushing plate 2, alignment pin 5 is installed in locating hole 2-2, and a hole on the position of locating hole 2-2 and bushing plate 2 aligns.
The structure of above-mentioned hold-down mechanism is: comprise bolt 6, pressing plate 7 and support column 8, the capitate end of bolt 6 is connected with supporting seat 1, on pressing plate 7, with elongated slot, the end of thread of bolt 6 passes equipped nut 9 after the elongated slot of pressing plate 7, and the side that support column 8 is positioned at bolt 6 is used for supporting pressing plate 7.In the present embodiment, the bilateral symmetry of bushing plate 2 is provided with two groups of hold-down mechanisms as above.
Using method of the present utility model:
Gear blank is placed between bushing plate 2 and supporting seat, circular trough on 3 of the defining flange 2-1 of bushing plate 2 and gears is engaged, locating hole 2-2 aims at symbol or the numeral on gear, nut 9 in the hold-down mechanism of rotary drilling template 2 both sides afterwards, make pressing plate 7 compress the both sides of bushing plate 2, this moment, gear 3 was fixed between bushing plate 2 and supporting seat 1, installation alignment pin 5 and hold out against character position on gear 3 in locating hole 2-2, and drill bit is completed boring by drill bushing 4 on gear.
