The invention relates to a drilling and locating fixture for a fabric-feeding presser foot of a sewing machine. The drilling and locating fixture is characterized by comprising a bent plate, locating pins, drill plates and a pressing mechanism, wherein the parts, corresponding to a workpiece datum hole and a datum plane, of the vertical surface of the bent plate are provided with two locating pin holes; the locating pins are fixedly connected in the locating pin holes; the parts, corresponding to the locating pins, of the vertical end surface of the bent plate are fixedly connected with the drill plates; the vertical surface of the bent plate is provided with the pressing mechanism for pressing a workpiece. The drilling and locating fixture has the beneficial effects that the structure is simple and the processing efficiency is high; the workpiece is accurately and reliably located by virtue of the workpiece datum plane and a process hole; all parts are arranged on the bent plate, so that the structure is simple and compact; the workpiece processing quality is ensured; after new products are on the market, the newly-increased annual profit of an enterprise is more than 125 thousand.
Description
Technical field
The invention belongs to frock clamp, particularly relate to a kind of Location Clamping Tool for Drilling Hole of sewing machine cloth feeding presser feet.
Background technology
Sewing-machine foot is requisite parts in the feed mechanism of sewing machine, various multi-form sewing-machine foot plays very important effect in process of production, as for seizing open-wire line, implicit type slide fastener sewing machine special presser feet, pleating sewing-machine foot etc., selects different sewing-machine foots extremely important in different sewing operations.
Industrial sewing machine piano work feed presser feet is the product that Novel industrial sewing machine is newly developed.Its complex structure, the dimensional accuracy of Each part and requirement on machining accuracy are all very high.Adopt digital processing center to process one by one, production cost is too high, does not have the market competitiveness.Such as, refer to shown in accompanying drawing 6, this piano presser feet product arranges 2-M3 bottom outlet on same level axis.Adopt pincers worker Drilling operation.Producing by batch must design specialized instrument.
Summary of the invention
The present invention is to overcome deficiency of the prior art, provides a kind of Location Clamping Tool for Drilling Hole of sewing machine cloth feeding presser feet, for location, the clamping of part, can complete the processing of privileged site two M3 bottom outlets on the same axis smoothly.
The present invention for achieving the above object, be achieved through the following technical solutions, a kind of Location Clamping Tool for Drilling Hole of sewing machine cloth feeding presser feet, it is characterized in that: comprise bent plate, alignment pin, bushing plate and hold-down mechanism, the vertical plane of described bent plate and workpiece datum hole and datum plane correspondence position are provided with two dowel holes, be connected with alignment pin in described dowel hole, the corresponding alignment pin position of described bent plate perpendicular end surface is connected with bushing plate, and the vertical surface of described bent plate is provided with the hold-down mechanism of workpiece pressing.
The dowel hole of described alignment pin and bent plate is interference fit.
Described bushing plate center is provided with drill jig, and described drill jig and bushing plate are interference fit.
Described drill jig adopts carbide alloy.
Described hold-down mechanism comprises pressing plate, hold-down bolt and carrying bolt, and described hold-down bolt through the centre bore in the middle of pressing plate, and is spirally connected with bent plate, and described carrying bolt is placed in the pressing plate bottom on opposite, workpiece pressing position, platen clamp or loosen workpiece.
Beneficial effect: structure is simple, and working (machining) efficiency is high, the location of workpiece relies on the datum plane of self and fabrication hole to locate, and accurate positioning is reliable.All parts are all arranged on bent plate, simple and compact for structure.Ensure that the crudy of workpiece, after new product puts goods on the market, the annual new profit of enterprise more than 12.5 ten thousand yuan can be made.
