Description
Technical field
The utility model is related to frock clamp fields, more particularly, to a kind of fixture.
Background technology
Fixture refers to that machine-building is used for fixing processing object in the process, is allowed to occupy correct position, to receive construction
Or the device of detection, also known as fixture.In a broad sense, any process in technical process is used for rapidly, easily and safely
The device for installing workpiece, all can be described as fixture.
Fixture is usually by setting element（Determine correct position of the workpiece in fixture）, clamping device, to knife induction element
(relative position or guiding tool orientation that determine cutter and workpiece), indexing means（Make workpiece that can complete number in once mounting
The processing of a station has circular index device and linear movement two class of indexing means）, connecting element and clamp body（Fixture bottom
Seat）Deng composition.
Fixture type can be divided by handling characteristics：1. universal fixture.As machine vice, chuck, sucker, dividing head and
Rotary table etc. has prodigious versatility, can preferably adapt to the transformation of manufacturing procedure and processing object, and structure has been determined
Type, size, specification seriation, wherein a kind of most of standard accessories for having become lathe.2. specificity fixture.For certain
Clamping of the product parts on certain procedure needs and specially manufactures and designs, and service object is single-minded, and specific aim is very strong, generally by producing
Product manufactory designed, designed.There are commonly turning attachment, fraise jig, drill jig, (guiding cutter drills on workpiece or reams use
Jig), the boring template jig of boring cutter bar bore hole on workpiece (guiding) and pallet（Certainly for building-block machine
Mobile clamping on moving-wire）.3. flexible jig.It can replace or the special fixture of adjustment element.4. built-up jig.By difference
The fixture of the standardized component composition of shape, specification and purposes is the single-piece often replaced suitable for trial production of new products and product, small
Criticize production and temporary duty.
Except vice, chuck, dividing head and rotary table etc, it is handle of a knife there are one more common, it is, in general, that knife
When tool this word of fixture occurs simultaneously, what this most fixture referred to is exactly handle of a knife.
Turning attachment, is used for the inside and outside surface of revolution of workpieces processing on lathe and the fixture of end face is known as turning attachment.Lathe
Fixture majority is mounted on main shaft, and minority is mounted on saddle or lathe bed.
Three coordinate fixtures, using its modular support and reference unit, are completed to surveyed workpiece using on measuring machine
Flexibility it is fixed.The device can carry out automated programming, realize the support to workpiece, and can establish unlimited work piece configuration ginseng
Examination point.Advanced special-purpose software can generate the clamping journey of workpiece directly by the geometric data of workpiece within several seconds
Sequence.
Industrial robot fixture, in industrial automation equipment, be modern industry automation equipment it is new into technology it
One.It is mainly appeared in modern industrial production with the fit form of robot, common usage is that lathe loading and unloading, workpiece tear code open
Pile, welding, grinding etc. automate in unmanned factory.
Fraise jig makees feed motion with platen.Mainly by positioning device, clamping device, clamp body, connection member
Part forms knife element.When Milling Process, cutting force is larger, and is interrupted cut, and vibration is larger, therefore the folder of fraise jig
Clamp force requirement is larger, and fixture rigidity, intensity requirement are relatively high.
Bearing block fixture improves the quality of production of bearing block, in addition to using lathe to ensure the quality of production of bearing block
Except equal mechanical equipments, can also use a large amount of technological equipment, include among these bearing block fixture, mold, cutter and
Related auxiliary tool.
Bearing block fixture is a kind of tool of production dedicated for guarantee bearing block product quality, can make bearing block
Production technology is more convenient.Different bearing block fixtures can all have according to its different structure and form, operating mode, design principle
Institute is different, therefore the type of bearing block fixture and pattern are varied, either still all occupies on pattern in quantity very big
Ratio.This bearing block fixture can be used for the relative position of accurately determination workpieces processing and stage property, that is, can incite somebody to action
It needs the workpiece processed to be stepped up, can thus complete the movement of the required progress among the process of work pieces process.By
Play the role of among bearing block production process in bearing block fixture very important, therefore bearing block fixture design drawing is painted
System is also extremely important.
Fig. 1 show a chain sprocket structure schematic diagram, and circular hole 112, and the inside of circular hole 112 are equipped among the sprocket wheel 111
It is set on wall there are one rectangular channel 113, after the chain wheel shaping, many burrs in surface need pair in order to ensure sprocket wheel is up-to-standard
Sprocket wheel carries out deburring, and during deburring, it needs to use special fixture to fix the plane, therefore, designer
It is special to develop a fixture for sprocket wheel deburring.
Invention content
A kind of the technical problem to be solved by the utility model is to provide structures sprocket wheel fixture simple, convenient for mounting and clamping.
Technical solution is used by the utility model solves above-mentioned technical problem：A kind of fixture, if including bottom plate, dry gas
Cylinder and several positioning cylinders, several positioning cylinders are divided into two row and are fixed on bottom plate, the bottom plate left side, right side
Side is equipped with several sliding slots, and the compression bar of positioning cylinder is right against in the sliding slot, and the compression bar can be in sliding slot laterally
Activity, several cylinders are separately positioned on the left and right sides of bottom plate and are corresponded with several sliding slots, on the cylinder
Piston rod connect with compression bar, the compression bar towards one end of positioning cylinder be in indent arc surfaced.
It is further improved as the utility model, the positioning cylinder is equipped with rectangular-shaped lug boss.The square of setting
The lug boss of shape, facilitates sprocket wheel to be assemblied on positioning column.
Compared with prior art, the utility model has the advantage of reasonable in design, clamping sprocket wheel is simple and convenient.Simply
For, the positioning cylinder of the utility model setting is used for the positioning of sprocket wheel, and the movement of compression bar is controlled by cylinder, the piston on cylinder
Bar can push compression bar to be moved to positioning cylinder, the sprocket wheel compressing that will be sleeved on positioning cylinder.
