Description

Cat's paw's formula gear end mill processing automatic positioning clamp

Technical field

The present invention relates to a kind of clamping apparatus for gear wheel processing, be specially a kind of cat's paw's formula gear end mill processing automatic positioning clamp.

Background technology

In Gear Processing industry, Milling Process is a kind of conventional machining mode.In the time carrying out process operation, need fixation workpiece, at this moment just need to use fixture.Traditional clamping scheme is, adopts fixing paw clamping, by this kind of processing scheme, because the size of gear and the variable thickness of axle head cause, need to look processed product situation replacing clamp, and the versatility of fixture is not strong, and production efficiency is low, and clamping is not firm.

Utility model content

The purpose of this utility model is to provide a kind of cat's paw's formula gear end mill processing automatic positioning clamp, improves the versatility of fixture, and automated exchanged cutter, enhances productivity, and ensures that clamping is firm, improving product quality.

For realizing above object, the technical solution adopted in the utility model is: cat's paw's formula gear end mill processing automatic positioning clamp, it comprises ring flange (1) and clamp body (2), described clamp body (2) upper end face is evenly provided with multiple bases (6), in described base (6), is combined with brace (3) by brace hole (201); Described brace (3) extends in the cavity of clamp body (2) through the brace hole (201) of clamp body (2) upper surface; Described brace (3) end is connected on terminal pad (10) by moveable hinge (7), described terminal pad (10) by-level is fixed with main tie (9), and described main tie (9) reaches outside clamp body (2) through the bottom (8) of clamp body (2) afterbody; Described brace (3) is fixed with paw (4) by bolt hole (401); Described paw (4) front end lower surface is set to arc head (403), and described arc head (403) front end is provided with profile of tooth pawl (404); In the middle of described clamp body (2) upper end face, be fixed with bearing (5), the surface of described bearing (5) is provided with serrate slot (501).

Further, described paw (4) rear end has expansion slot (402).

The beneficial effects of the utility model: 1, adopt the fixing pressure head of brace clamping, not limited by the product size of gear to be processed, can regulate arbitrarily suitable clamping height, fixture versatility is strengthened, and production efficiency improves; Use screw threads for fastening, the fixing of clamping is stronger simultaneously.

2, on clamp body, be provided with bearing, and abutment surface is provided with serrate slot, pressure head front end is provided with profile of tooth pawl, is more conducive to fixing gear to be processed, avoids processing to rock, and is conducive to promote the product quality of gear to be processed.

3, adopt pull bar automated exchanged cutter, the trouble of avoiding dismounting to compress has improved operating efficiency simultaneously.
