Abstract
The invention discloses a machining jig. The machining jig comprises a base, support bars, movable bars, elastic clamps and a tapered extrusion head, wherein the two support bars are fixed on the base and symmetrically arranged; a limit slot is formed in the top of each support bar; the movable bars are arranged in the limit slots; one end of each movable bar is connected with one of the elastic clamps, and a ring groove is formed in the other end of each movable bar; the tapered extrusion head is arranged between the two ring grooves; a handle is fixed above the tapered extrusion head; threads are formed in the tapered surface of the tapered extrusion head; the screw pitch of the threads on the tapered surface of the tapered extrusion head is equal to the thickness of the movable bars; the sizes of the limit slots fit in with those of the movable bars; and the inner surfaces of the ring grooves of the movable bars are inclined, and the inclined planes are parallel to the conical surface. On the whole, the machining jig has the advantages of being simple in structure, simple and convenient to operate and high in machining precision.
Description
Technical field
The invention belongs to machinery tool field, relate to a kind of machining tool.
Background technology
Tool refers to be used for fixing processing object during machine-building, is allowed to occupy correct position, to accept to execute
Work or the device of detection.When machine tool processing workpiece, drawing specifies in order to make the surface of workpiece to reach dimensions, geometry with
And with the technology requirements such as the relative-position error on other surfaces, workpiece should be positioned before processing, clamp.Tool of the prior art
When clamping workpiece, easy run-off the straight and shift phenomenon, reduce the precision of processing, have impact on the quality of processing.
Summary of the invention
It is an object of the invention to provide a kind of machining tool, this jig structure is simple, easy to operate, it is possible to increase
The precision of ring-shaped work pieces processing, has high use value.
The object of the present invention is achieved like this: a kind of machining tool, including base, support bar, motion bar, elasticity
Chuck, tapered squeezing head, described base is fixed with two support bars, and described support bar is arranged symmetrically with, described support
The top limited location groove of bar, is provided with motion bar in described stopper slot, one end of described motion bar connects flexible chuck,
The other end of described motion bar is cannelure, is provided with tapered squeezing head, described taper between two described cannelures
The top of extrusion head is fixed with a handle, and the conical surface of described tapered squeezing head has screw thread.
The size of described stopper slot is agreed with mutually with the size of motion bar, and coating lubricating oil in stopper slot.
The side of described collet is arcwall face, and the side of arcwall face is towards outside.
The inner surface of the cannelure of described motion bar tilts, and inclined plane is parallel with the conical surface.
The pitch of described tapered squeezing nose cone shape thread surface is identical with the thickness of motion bar.
The beneficial effect comprise that: on motion bar, fix collet, enable collet the most movable
To adapt to various sizes of annular workpieces such that it is able to greatly strengthen the scope of application of tool；Only need to be by annular work during use
Part is enclosed within collet, then turns the handle of tapered squeezing head, and along with tapered squeezing head moves downward, motion bar promotes and squeezes
Annular workpieces is securely fixed by pressure head, is then processed workpiece, thus improves the machining accuracy of workpiece.

Fig. 1 is the perspective view of the present invention.
Fig. 2 is top view at cannelure of the present invention.
Fig. 3 is the profile of the present invention.
In figure: 1, base 2, support bar 3, motion bar 4, collet 5, tapered squeezing 6, stopper slot 7, annular
Groove 8, handle.
Detailed description of the invention
Below in conjunction with the accompanying drawings to embodiments of the invention further instruction.
Embodiment 1
As illustrated in the accompanying drawings from 1 to 3, a kind of machining tool, squeezes including base 1, support bar 2, motion bar 3, collet 4, taper
Pressure head 5, described base 1 is fixed with two support bars 2, and described support bar 2 is arranged symmetrically with, the top of described support bar 2
Portion's limited location groove 6, is provided with motion bar 3 in described stopper slot 6, one end of described motion bar 3 connects flexible chuck 4,
The other end of described motion bar 3 is cannelure 7, is provided with tapered squeezing 5 between two described cannelures 7, described
The top of tapered squeezing 5 is fixed with a handle 8, and the conical surface of described tapered squeezing 5 has screw thread.
The size of described stopper slot 6 is agreed with mutually with the size of motion bar 3, and coating lubricating oil in stopper slot 6.
The side of described collet 4 is arcwall face, and the side of arcwall face is towards outside.
The inner surface of the cannelure 7 of described motion bar 3 tilts, and inclined plane is parallel with the conical surface.
The pitch of described tapered squeezing 5 conical surface screw thread is identical with the thickness of motion bar 3.
The present invention is in use: a kind of machining tool, and base is fixed with two symmetrical support bars, support bar
Locating slot is arranged at top, installation activity bar in locating slot, and coating lubricating oil in locating slot, with freely transporting of Support activity bar
Dynamic, the collet of arc it is installed with in one end of motion bar.During use, workpiece is placed between two collets,
Then turning the handle of tapered squeezing head, tapered squeezing head promotes motion bar to move during moving downward, so that living
Workpiece is securely fixed by the collet of end part of movable rod.
Generally, the advantage that the present invention has simple in construction, easy and simple to handle, machining accuracy is high.
