Abstract

The utility model relates to an eccentric fixture for a lathe, particularly to an eccentric fixture for machining parts with claws on an ordinary lathe. The eccentric fixture comprises a fixture main body, a dividing plate, a positioning pin, a positioning shaft, screws and pressing plates, wherein fixture main body is of a T-shaped structure; the dividing plate is of a convex structure and is connected to a place above the level segment of the T-shaped fixture main body through the positioning pin and the positioning shaft; the dividing plate and the fixture main body are pressured by L-shaped pressing plates on the left side and the right side of the dividing plate; the pressing plates are connected and fixed through the screws; the vertical segment of the T-shaped fixture main body is of the type of Morse taper. The eccentric fixture has the advantages that the fixture can be used for machining shaft or sheet parts with claws on the ordinary lathe, and has fixing effects in the machining process without off tracking or sliding; repeated correction is not needed; the machining efficiency is high and the eccentric fixture is suitable for batch production.

Description

A kind of lathe eccentric fixture

Technical field

The utility model relates to a kind of lathe eccentric fixture, is the eccentric fixture for processing belt pawl part on engine lathe specifically.

Background technology

At present, if do not use Special tooling clamp on engine lathe, cannot processing belt pawl part, autocratic frock be must design and clamping, correction carried out.In prior art, also have the simple and easy fixture of employing to carry out clamping, but its fixed effect is bad, in process, easily sideslip, the correction operation that must carry out repetition, this correction operation is comparatively loaded down with trivial details, and difficulty is large, and processing operating efficiency is low, is unsuitable for producing in enormous quantities.

Summary of the invention

In order to overcome the defect existing in prior art, when the utility model object is to provide one to carry out axle class or sheet class end face band pawl part on lathe, to proofread and correct without repeating, working (machining) efficiency is high, is suitable for the lathe eccentric fixture of producing in enormous quantities.

To achieve these goals, the utility model is by the following technical solutions:

The utility model provides a kind of lathe eccentric fixture, comprise chuck body, index dial, alignment pin, locating shaft, screw, pressing plate, described chuck body becomes " T " character form structure, described index dial is for " protruding " character form structure and adopt alignment pin and locating shaft is connected to the top of the horizontal segment of described " T " font chuck body, the described index dial left and right sides adopts " L " type pressing plate to push down index dial and chuck body, be connected and fixed pressing plate with screw, described " T " font chuck body vertically section is Morse's taper type.

Described " protruding " font index dial and workpiece are fixed connection with nut.

Described pressing plate is " L " type structure.

Compared with prior art, the utlity model has following advantage:

1. the fixture that provides of the utility model is provided, can be on engine lathe working shaft-like or sheet class end face band pawl part.

2. before processing, adopt the utility model fixation workpiece, good fixing effect in process, can sideslip or slip, proofreaies and correct without repeating, and working (machining) efficiency is high, is suitable for producing in enormous quantities.

Brief description of the drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is A-A cutaway view in Fig. 1;

Fig. 3 is B-B cutaway view in Fig. 1;

In figure: chuck body 1, index dial 2, alignment pin 3, nut 4, locating shaft 5, screw 6, pressing plate 7.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is further described:

As Figure 1-3: the utility model provides a kind of lathe eccentric fixture, comprise chuck body 1, index dial 2, alignment pin 3, locating shaft 5, screw 6, pressing plate 7, 1 one-tenth " T " character form structure of described chuck body, described index dial 2 is " protruding " character form structure, and adopt alignment pin 3 and locating shaft 5 to be connected to the top of the horizontal segment of described " T " font chuck body, the described index dial left and right sides adopts " L " type pressing plate 7 to push down index dial 2 and chuck body 1, be connected and fixed pressing plate with screw, described " T " font chuck body vertically section is Morse's taper type, be used for stationary fit accurately to locate, be free to dismounting.

Described " protruding " font index dial 2 and workpiece adopt nut 4 to be fixed connection.

Described pressing plate 7 is " L " type structure, its good fixing effect.

In process, according to the shape of processing parts, as the end face band pawl part of sheet class, according to the size in hole, adjust the size of locating shaft 5, as the part of the end face band pawl of axle class, take out locating shaft 5, directly locate with the hole of index dial 2.Just can working shaft-like and sheet class end face band pawl part, adjust the quantity in the hole of clamp body 1, just can process the band pawl part that quantity is different.

In clamping engineering, now clamp body 1 is packed in lathe main axis hole, again index dial 2 is contained on clamp body 1, index dial is fixed on clamp body 1 with screw 6 and pressing plate 7, as process the end face band pawl part of sheet class, locating shaft 5 is packed on index dial 2, part is packed on locating shaft 5, use again nut 4 compressing components, be locked on index dial, insert on index dial 2 and clamp body 1 with alignment pin 3, often process a pawl, take out alignment pin 3, rotate index dial 2, insert in another hole on clamp body 1 with alignment pin 3, process another pawl, rotate successively index dial 2 and insert alignment pin 3 pawl that just can process varying number.As working shaft-like part, just take out locating shaft 3, with the location, hole of index dial 2, by above-mentioned action request, just can working shaft-like end face band pawl part.
