Abstract
The utility model relates to a drilling clamp for two mutually vertical holes in a cloth feeding presser foot of a sewing machine. The drilling clamp is characterized by comprising a clamp body, wherein the clamp body is square; a rectangular open groove is formed transversely on one side face of the clamp body; the rectangular open groove is connected with a compression mechanism; the clamp body is provided with drilling dies. The drilling clamp has the beneficial effects that a workpiece is positioned by means of profile, so that positioning can be performed easily and reliably. Drilling dies for forming different holes are arranged on different surfaces of the clamp body, and holes in different surfaces of parts are formed by overturning a tool. All parts are arranged on the clamp body, so that the structure is simple and compact. The machining quality of the workpiece is ensured, and the annual profit of an enterprise can be increased by over 125,000 yuan after a new product is introduced into the market.
Description
Technical field
The utility model belongs to frock clamp, relates in particular to the boring grab of the mutual two holes with vertical of a kind 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 foots play very important effect in process of production, as for seizing open-wire line, hidden 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 several part structure and requirement on machining accuracy are all very high.Adopt digital processing center to process one by one, production cost is too high, there is no the market competitiveness.For example, refer to shown in accompanying drawing 4, this piano presser feet product is designed with 2-M3 on same level axis, and screw bottom is provided with through hole φ 3 with its center line upright position, and object is the convenient processing of the bottom outlet of screw, also facilitates tap tapping, is equivalent to " escape ".Have the blind hole of φ 3.8 with datum plane A vertical design, the blind hole center line of this φ 3.8 is mutually vertical with the center line of φ 3 through holes, but not in a plane, the geometric accuracy in two holes (position work is poor) requires very high, and object is to guarantee that the interchangeability of workpiece is high.Adopt pincers worker Drilling operation.Producing by batch must design specialized instrument.
Utility model content
The utility model is in order to overcome deficiency of the prior art, and the boring grab of the mutual two holes with vertical of a kind of sewing machine cloth feeding presser feet is provided, and for location, the clamping of part, can complete smoothly the blind hole of privileged site φ 3.8 and the processing of φ 3 through holes simultaneously.
The utility model for achieving the above object, be achieved through the following technical solutions, the boring grab of the mutual two holes with vertical of a kind of sewing machine cloth feeding presser feet, it is characterized in that: comprise chuck body, described chuck body shape is square, described chuck body is laterally provided with oblong openings groove on one side, and described oblong openings groove is connected with hold-down mechanism, and described chuck body is provided with drill jig.
Described oblong openings bottom land limit is parallel with chuck body side, forms the location basal plane of fixture.
Described oblong openings well width and the degree of depth and the width of the workpiece and thickness matching.
The position, hole of the corresponding workpiece design of described chuck body arranges drill jig, and described drill jig is in right angle setting, completes two processing that are mutually hole, right angle.
Described drill jig and chuck body are interference fit.
Described drill jig adopts carbide alloy.
Described hold-down mechanism adopts in chuck body affixed handle centering type fast-assembling jackscrew or the chuck body hold-down bolt that is spirally connected, and described fast-assembling jackscrew or hold-down bolt, realize Work-sheet pressing or unclamp.
Beneficial effect: the outer shape of workpiece location, locate simple and reliable.The drill jig of processing different holes is arranged on the different surfaces of chuck body, the hole of the upset processing parts different surfaces by frock, and all parts are all arranged in chuck body, simple and compact for structure.Guaranteed the crudy of workpiece, after new product puts goods on the market, more than 12.5 ten thousand yuan of the annual new profits of Ke Shi enterprise.

The specific embodiment
Below in conjunction with preferred embodiment, to the specific embodiment providing according to the utility model, details are as follows:
Embodiment
Refer to accompanying drawing 1-3, the utility model provides the boring grab of the mutual two holes with vertical of a kind of sewing machine cloth feeding presser feet, comprise chuck body 1, described chuck body shape is square, described chuck body is laterally provided with oblong openings groove 6 on one side, described oblong openings groove is connected with hold-down mechanism, and described chuck body is provided with drill jig.Described oblong openings bottom land limit is parallel with chuck body side, forms the location basal plane of fixture.Described oblong openings well width and the degree of depth and the width of the workpiece and thickness matching.The position, hole of the corresponding workpiece design of described chuck body arranges φ 3.8 and 3 two drill jigs of φ, and described drill jig is in right angle setting, completes two processing that are mutually hole, right angle.
3 drill jigs (3)
3.8 drill jigs (4) are arranged on the drill jig hole of body (1) by interference fit.Hole that can processing parts different surfaces.Described drill jig adopts carbide alloy.Workpiece blank is precision castings, and appearance and size is more accurate, high conformity, therefore can utilize blank shape location to process, chuck body plays the effect of workpiece location and bushing plate simultaneously, and drill jig is arranged on the orthogonal different surfaces of chuck body, and a set of frock plays the effect of two cover frocks.Described hold-down mechanism adopts affixed handle centering type fast-assembling jackscrew in chuck body, and hold-down mechanism is pushed down to workpiece, can be put on drilling machine and hole.
Preferred version of the present utility model is, at the chuck body hold-down bolt that is spirally connected, hold-down bolt is tightened or unclamped, and can realize and compresses or loosen workpiece.The sewing machine cloth feeding presser feet (hereinafter to be referred as workpiece) of accompanying drawing 4 of take is example: workpiece is placed in the oblong openings groove of chuck body → screws hold-down bolt workpiece pressing → start processing
3 holes →
3 hole completion of processing → frocks are turned over and are turn 90 degrees → start processing
3.8 holes →
the iron filings of 3.8 hole completion of processing → loosen hold-down bolt → taking-up workpiece → blow off in body die cavity are prepared the next workpiece of processing.
