Abstract
A fixture for surfacing comprises a chuck and a claw of a lathe, a central pin and an antiskid bolt; wherein the central pin is fixed in the claw; and the antiskid bolt is fixed on the chuck. An antiskid rod is arranged in parallel on the antiskid bolt. The central pin is matched with the hole of the end surface of a workpiece to be machined. The end surface of the claw is a machining positioning surface which is perpendicular to the central pin. The fixture is mainly used in the machining of various end surfaces. One end of a workpiece is fixed by the central pin, the other end of the workpiece is mounted on the antiskid bolt of the fixture, and the workpiece is clamped by the centrifugal force of the rotation of the main shaft of the lathe and the cutting force generated by a tool in the process of machining. Consequently, the problem of the roughness and parallelism of various special-shaped end surfaces is solved, the clamping of the chuck cannot cause the plastic deformation of the workpiece, operation is convenient, and the machining quality is reliable.
Description
Technical field
The utility model relates to a kind of anchor clamps of face work, particularly relates to the anchor clamps of a kind of face work in the processing technology of engine link.
Background technology
Lathe is the lathe that mainly with lathe tool the workpiece of rotation is carried out turning processing.Also available drill bit, reamer, reamer, screw tap, screw die and checkering tool etc. are processed accordingly on lathe.Lathe is mainly used in and processes axle, dish, overlaps and other have the workpiece of rotary surface, is to use a widest class lathe in machine-building and the repair factory.At present, the traditional processing technology of engine link end face attenuate has following method, 1. monoblock type: connecting rod concentric reducer hole end surface attenuate, adopt grinding machine to carry out two-sided while grinding.2. split type: the variable thickness of big end end and small end of connecting rod end attenuate causes, and adopts secondary milling or grinding.The processing of connecting rod end face is processed after needing to adopt special fixture and gripper chuck clamping of workpieces.All kinds of end face class parts of processing because of the restriction of its shape and material, generally adopt milling, grinding etc. in the traditional handicraft.Add man-hour because the inhomogeneous meeting of thrust causes the bigger thin-wall part of some plastic deformations to produce distortion, thereby cause workpiece accuracy defective, it is more to produce faulty part.
Summary of the invention
The purpose of this utility model is the deficiency that exists in the processing at existing end face class part, and a kind of anchor clamps of face work are provided.The distortion difficult problem that the problem that solves produces when being Work-sheet pressing.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of anchor clamps of face work comprise the chuck and the claw of lathe; It is characterized in that: centrepin and anti-skidding bolt are set, and centrepin is fixed in the claw, anti-skidding being bolted on the chuck.
For better anti-skidding connecting rod class workpiece, antiskid bar be arranged in parallel on described anti-skidding bolt.
Described centrepin and processed work end face are adaptive.
Described claw end face is the processing locating surface, and described centrepin is vertical with locating surface.
Operation principle of the present utility model is, mainly be exactly that workpiece is under the lathe spindle action of centrifugal force, utilize the self-centering principle of workpiece, workpiece is fixed on the chuck face processes, the cutter normal direction cutting force that work in-process produces has the effect that compresses to workpiece, compresses thereby need not any other mechanical type.
Good effect of the present utility model: mainly be to be used for all kinds of end face processing, workpiece one end is by the location of centrepin, the other end is installed on the anti-skidding bolt of anchor clamps, plays the effect that compresses by the action of centrifugal force of lathe spindle rotation and the cutting force of work in-process cutter generation.Thereby solved the roughness and the depth of parallelism of all kinds of special-shaped part end faces, can be because of chuck compresses the plastic deformation that causes workpiece, easy to operate, crudy is reliable.Compare with traditional technology, improved the processing beat, saved a large amount of cutters and frock expense, guarantee the machining accuracy of workpiece, main is that the process economics type is improved, and has reduced the cost of part, has strengthened the competitiveness of product on market.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the anchor clamps organigram of face work.
Among the figure: 1. chuck, 2. centrepin, 3. anti-skidding bolt, 4. antiskid bar, 5. locating surface, 6. claw.
The specific embodiment
As shown in Figure 1, a kind of anchor clamps of face work comprise the chuck 1 and the claw 6 of lathe centrepin 2 and anti-skidding bolt 3 being set also that centrepin 2 is fixed in the claw 6, anti-skidding being bolted on the chuck 1.
For better anti-skidding connecting rod class workpiece, antiskid bar 4 be arranged in parallel on described anti-skidding bolt 3.
Described centrepin 2 is adaptive with processed work end face.Described claw 6 end faces are processing locating surfaces 5, and described centrepin 2 is vertical with locating surface 5.
When the workpiece (as engine link) of processing long and narrow class band circular port and approaching, can on lathe, finish the processing on two surfaces by useful this clamp body.Process is, workpiece one end locating hole is installed in centrepin 2 places, and the workpiece other end is put between anti-skidding bolt 3 and the antiskid bar 4, pushes workpiece to locating surface 5 places and workpiece is fitted, and starts lathe, the processing end face.Can well guarantee flatness, and the flexibility of workpiece can be good at also guaranteeing.
Certainly, adopting these anchor clamps also to need certain condition, at first is that the shape to part has requirement, and the difference of different part anchor points will have different anchor clamps.
