Abstract

The utility model discloses a pneumatic type gear end milling location clamp, and belongs to the field of gear machining clamps. The pneumatic type gear end milling location clamp comprises a flange plate and a clamp body. A plurality of bases are uniformly arranged on the surface of the upper end of the clamp body, and inclined pull rods are matched inside the bases through inclined rod holes. The inclined pull rods penetrate through the inclined rod holes in the upper surface of the clamp body and extend into a cavity of the clamp body. The tail ends of the inclined pull rods are connected to a connection plate through movable hinges, and a main pull rod is horizontally fixed to the middle of the connection plate, penetrates out of a bottom cover on the tail portion of the clamp body and extends out of the clamp body. Pressing claws are fixed to the inclined pull rods through bolt holes, and arc-shaped heads are arranged on the lower surfaces of the front ends of the pressing claws. A support is fixed to the middle of the surface of the upper end of the clamp body. According to the pneumatic type gear end milling location clamp, the universality of the clamp is improved, automatic clamping is achieved, the production efficiency is improved, clamping is firm, and the product quality is improved.

Description

Pneumatic type gear end mill positioning clamp for machining

Technical field

The present invention relates to a kind of clamping apparatus for gear wheel processing, be specially a kind of pneumatic type gear end mill positioning clamp for machining.

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 pneumatic type gear end mill positioning clamp for machining, 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: pneumatic type gear end mill positioning clamp for machining, 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); In the middle of described clamp body (2) upper end face, be fixed with bearing (5).

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, be conducive to fixing gear to be processed, avoid processing to rock, be 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.

Detailed description of the invention

In order to make those skilled in the art understand better the technical solution of the utility model; below in conjunction with accompanying drawing, the utility model is described in detail; the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.

As Figure 1-4, assembly relation of the present utility model is: it comprises ring flange 1 and clamp body 2, and described clamp body 2 upper end faces are 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 surfaces; Described brace 3 ends are connected on terminal pad 10 by moveable hinge 7, and described terminal pad 10 by-levels are fixed with main tie 9, and described main tie 9 reaches outside clamp body 2 through the bottom 8 of clamp body 2 afterbodys; Described brace 3 is fixed with paw 4 by bolt hole 401; Described paw 4 front end lower surfaces are set to arc head 403; In the middle of described clamp body 2 upper end faces, be fixed with bearing 5.

Further, described paw 4 rear ends have expansion slot 402.The setting of expansion slot 402 is convenient to dismantle paw 4.

When concrete operations, fixture is arranged on lathe, the air pressure retractor device of main tie 9 connecting machine tools, regulate after equipment, gear 101 to be processed is placed on bearing 5, then starts main tie 9, drive brace 3 to strain paw 4 by moveable hinge 7, utilize its arc head 403 to block the gear teeth of gear 101, realize the tight gear 101 to be processed of clamping.

It should be noted that, in this article, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thereby which key element the process, method, article or the equipment that make to comprise a series of key elements not only comprise, but also comprise other key elements of clearly not listing, or be also included as the intrinsic key element of this process, method, article or equipment.
