Abstract

A combined type fixture is characterized by comprising a sealing component and at least one set of clamping fastening ferrule component, wherein the sealing component is provided with a sealing action surface which is used for sealing an opening of an imperfect hole of a part to be machined. The clamping fastening ferrule component comprises a left half ferrule body, a right half ferrule body and a fastening piece, wherein the left half ferrule body and the right half ferrule body are used for being arranged on the whole pieced periphery of the part to be machined and the sealing component in a clamping mode, the conterminous end portions of the left half ferrule body and the right half ferrule body are firmly connected through the fastening piece, and therefore the sealing action surface of the sealing component presses tightly on the opening of the imperfect hole of the part to be machined. Due to the application of the combined type fixture, the imperfect hole of the part to be machined is sealed to form a perfect hole, the inner circle surface of the hole is machined conveniently by means of extrusion honing machining process, namely the inner circle surface of the hole is machined under the skiving action of flowing grinding materials on an extrusion honing machine, the machining efficiency is greatly improved, and the combined type fixture is quite suitable for machining of mass parts.

Description

A kind of modular fixture

Technical field

The utility model relates to and adds the anchor clamps of using man-hour, is specifically related to a kind of internal circular surfaces that is used for the imperfect hole of part and carries out extrusion honing and add used modular fixture in man-hour.

Background technology

Part with imperfect hole is meant that certain hole on the part is not sealed, and just the part in this hole is opened wide, and therefore can't directly use high efficiency extrusion honing processing technology and process.The extrusion honing processing technology is meant and utilizes viscoplasticity substrate medium (abrasive media) the repeated friction finished surface and reach polishing or remove the special process of burr effect under certain pressure carry abrasive material, claims the abrasive material processing of flowing again.So can only grind by hand its internal circular surfaces is processed at present; Not only the amount of labour is bigger, and clamp structure is complicated, and cost is higher; And working (machining) efficiency is extremely low; Therefore can only process single-piece or parts in small batch, defectives such as " subsiding " very easily appears in the part after the processing in indentation, there simultaneously, so that can influence the serviceability of part.Do not seal because of certain hole on the part, can't be suitable for the extrusion honing processing technology again.

Summary of the invention

The utility model provides a kind of modular fixture, utilizes these anchor clamps that the imperfect hole on the part is sealed, thereby becomes a complete hole, so that with the extrusion honing processing technology its internal circular surfaces is processed.

For achieving the above object; The technical scheme that the utility model adopts is: a kind of modular fixture; Comprise a packaged unit and at least one cover bail assembly, have the sealing process face of the opening part in the imperfect hole that is used for shutoff part to be processed on the said packaged unit; Said bail assembly comprises left half hoop body, right half hoop body and securing member; A said left side half hoop body, the confession of right half hoop body are folded on the whole periphery after part to be processed and the packaged unit amalgamation; Be fastenedly connected with securing member between the end that a left side half hoop body, right half hoop body join, the sealing process face of packaged unit be pressed in the opening part in the imperfect hole of part to be processed with this.

Related content in the technique scheme is explained as follows:

1, in the such scheme, the dual-side of the opening part in the imperfect hole of corresponding part to be processed respectively is provided with the positioning table terrace on the said sealing process face.

2, in the such scheme, said packaged unit is an an arc watt shape body, and the intrados of this arc watt shape body is the situation of the annular solid of an open loop shape as said sealing process face to be applicable to part to be processed.

3, in the such scheme, said securing member is meant the fastening parts of using such as bolt and nut, screw.

The utility model design concept and the effect of bringing:

The utility model provides a kind of modular fixture; Utilize these anchor clamps can make the incomplete hole shutoff on the part become a complete hole; So that the internal circular surfaces in hole is processed with the extrusion honing processing technology; Promptly can on squeezing honing machine, process the internal circular surfaces in hole, and defectives such as " subsiding " can not appear in the processing back in indentation, there through the scraping action of the abrasive material that flows.These anchor clamps have simple in structure, and are with low cost, make easily, and flexible and convenient operation, the while can be brought into play the advantage of extrusion honing processing technology, and efficient can improve greatly, is fit to very much the processing to part in enormous quantities.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Embodiment one: shown in accompanying drawing 1～accompanying drawing 6,

A kind of modular fixture comprises a packaged unit 1 and two cover bail assemblies 2, has the sealing process face 4 of the opening part in the imperfect hole that is used for shutoff part 3 to be processed on the said packaged unit 1.Specifically, the part to be processed 3 that present embodiment is suitable for is the annular solid of an open loop shape, shown in accompanying drawing 4.So; Packaged unit 1 is specially an arc watt shape body; The intrados of this arc watt shape body is as said sealing process face 4, and the dual-side (being the both ends of open loop) of the opening part in the imperfect hole of corresponding part 3 to be processed respectively is provided with positioning table terrace 5 on this sealing process face 4.And; The present embodiment modular fixture also comprises an accessory 6; Periphery after accessory 6 and packaged unit 1 and part 3 amalgamations to be processed is compared the form fit of the part that is lacked with full circle, promptly as shown in Figure 5, accessory 6 also is the annular solid of an open loop shape.Said bail assembly 2 comprises left half hoop body 7, right half hoop body 8 and securing member, and like diagram, said securing member is nut 9 and bolt 10.

Shown in accompanying drawing 1, accompanying drawing 2; Packaged unit 1 with the opening part in sealing process face 4 and the imperfect hole of part 3 to be processed against amalgamation mutually; The sheathed again accessory 6 in the outside of part 3 to be processed; A left side half hoop body 7, right half hoop body 8 are folded in part to be processed 3, packaged unit 1 adds on the whole periphery after accessory 6 amalgamations; Be fastenedly connected with nut 9 and bolt 10 between the end that a left side half hoop body 7, right half hoop body 8 join, the sealing process face 4 of packaged unit 1 be pressed in the opening part in the imperfect hole of part 3 to be processed with this.

The application of present embodiment modular fixture; Make the incomplete hole shutoff on the part 3 to be processed become a complete hole; So that the internal circular surfaces in hole is processed with the extrusion honing processing technology; Promptly can on squeezing honing machine, process the internal circular surfaces in hole, and defectives such as " subsiding " can not appear in the processing back in indentation, there through the scraping action of the abrasive material that flows.The utility model modular fixture has simple in structure, and is with low cost, make easily, and flexible and convenient operation, the while can be brought into play the advantage of extrusion honing processing technology, and efficient can improve greatly, is fit to very much the processing to part in enormous quantities.

The material of said packaged unit 1 can be used and part 3 identical materials to be processed or other high-abrasive material,, only need change a new packaged unit 1 and get final product owing to use for a long time when wearing and tearing comparatively seriously when packaged unit 1.
