Abstract

The utility model relates to a fixture for a planet carrier lathe, which is characterized in that the fixture comprises a fixture body, wherein the center of the fixture body is provided with a centering orifice; an eccentric orifice is arranged below the centering orifice; a locating central spindle with an unequal-diameter structure is penetrated in the eccentric orifice; the locating central spindle is clamped with one side surface of the fixture body by a great circle part; the small circle part of the locating central spindle is embedded on the eccentric orifice; one side surface of the fixture body is provided with a counter weight and is provided with an indexing locating block by an indexing locating rack; and a screw barrel for installing bolts is embedded on the lower end of the fixture body. The fixture is characterized in that the fixture has high machining accuracy and is convenient to operate when being used for machining a planet carrier of a planetary reducer, expensive machining centers and special machining tools can be replaced by the fixture, and processing cost is greatly lowered. Thus, the fixture has good adaptability in medium volume production.

Description

Planet carrier lathe anchor clamps
Technical field
The utility model belongs to lathe and uses the anchor clamps field, particularly relates to a kind of planet carrier lathe anchor clamps.
Background technology
Planetary reducer has that volume is little, in light weight, speed ratio reaches characteristics such as efficient height greatly, is the transmission mechanism of outbalance in the present reductor.The critical component of planetary reducer---planet carrier is supporting planetary gear and the parts that transmit moment of torsion, and its structure is varied.Along with the development and the raising of technology, the cantilevered planet carrier is used because of its compact conformation is more, but its processing is comparatively difficult.This is that in order to guarantee the gear drive correct engagement, the position degree of minor axis is had relatively high expectations because the minor axis of 5 protrusions of cantilevered planet carrier is to be used for installing planetary, and special shape and high accuracy are that engine lathe is unmanageable.At present, traditional processing method is that the work in-process heart adopts special tool to carry out machining, and this kind processing method is the cost height not only, but also will order special process tool, therefore is difficult to be applicable to the middle batch machining of these parts.
Summary of the invention
The utility model is for solving the planet carrier lathe anchor clamps that the technical problem that exists in the known technology provides a kind of processing simple in structure, convenient and can cut down finished cost.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: planet carrier lathe anchor clamps, it is characterized in that: comprise clamp body, described clamp body center is shaped on alignment holes, be positioned at the alignment holes below and be shaped on eccentric orfice, be coated with the positioning core axle that does not wait gauge structure on the described eccentric orfice, described positioning core axle clamps by big circular portion and clamp body one side, the little circular portion of positioning core axle is inlaid on the eccentric orfice, described clamp body also is provided with counterweight on one side, this side is equipped with the calibration locating piece by the calibration locating rack, and the clamp body lower end is embedded with the swivel nut that is used for mounting screw.
The utility model can also adopt following technical scheme:
The alignment holes at described clamp body center and the distance of eccentric orfice are the eccentric throw of processing work.
Advantage and the good effect that the utlity model has are: the planet carrier that uses these anchor clamps processing planetary reducer, not only easy and simple to handle, machining accuracy is high, but also can replace expensive machining center and special process tool, reduced processing cost significantly, so these anchor clamps has good adaptability in medium quantity batch processing.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the utility model user mode figure.
Among the figure: 1, positioning core axle; 1-1, big circular portion; 1-2, little circular portion; 2, swivel nut; 3, adjusting pad; 4, counterweight; 5, workpiece; 6, clamp body; 6-1, centre bore; 6-2, eccentric orfice; 7, calibration locating rack; 8, calibration locating piece.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, planet carrier lathe anchor clamps comprise a discoid clamp body 6, are shaped on alignment holes 6-1 at the clamp body center, be positioned at alignment holes 6-1 below and be shaped on eccentric orfice 6-2, the alignment holes at described clamp body center and the distance of eccentric orfice are the eccentric throw of processing work.Be coated with the positioning core axle 1 that does not wait gauge structure on the described eccentric orfice, described positioning core axle clamps by big circular portion 1-1 and clamp body 6 one sides, and the roundlet part 1-2 of positioning core axle is inlaid on the eccentric orfice.Roundlet part 1-2 on the described positioning core axle is contained in the eccentric orfice of clamp body 6, and big circular portion 1-1 matches with the endoporus of workpiece 5.In order to make whole clamp body keep good balance, because the vibration that imbalance produces also is fixed with counterweight 4 on clamp body one side, can avoid the influence of the additional load that causes owing to balanced differences like this when reducing turning to the lathe spindle bearing.By calibration locating rack 7 calibration locating piece 8 is installed in this side.The clamp body lower end is embedded with the swivel nut 2 that is used for mounting screw, and described swivel nut 2 is fixed processing work and clamp body by screw as a field-replaceable unit, can avoid like this dismantling repeatedly and cause thread damage or screw thread damage in long-time the use.
Operation principle of the present utility model is:
See also Fig. 3, at first anchor clamps and lathe floral disc are linked into an integrated entity by screw, the end face run-out amount of centering clamp body is utilized the alignment holes 6-1 centering anchor clamps center on the clamp body and the concentricity of lathe spindle in allowed band, check whether the counterweight situation is good.Install workpiece 5 this moment on clamp body, and between workpiece 5 and clamp body adjusting pad 3 is installed, and can guarantee that by adjusting pad 3 machining benchmark and design, technological datum unify, and helps reducing error accumulation.1# cylindrical on the centering workpiece 5 then, workpiece pressing, each size such as processing excircles.After treating that the 1# cylindrical machines on the workpiece, calibration locating piece 8 is mounted on the anchor clamps, unclamps workpiece 5 and rotational workpieces, utilize the 1# cylindrical to press close to calibration locating piece surface and carry out the calibration location, workpiece 2# this moment cylindrical to be processed has forwarded Working position to, each size of processing work 2# cylindrical.Repeat above-mentioned steps, successively workpiece 3#, 4#, 5# cylindrical are machined.
These anchor clamps and processing method also can be used for processing the parts that other similarly has the degree requirement of high eccentricity position.
