Description
Technical field
The utility model relates to field of machining, particularly the adjustable damping special jig of a kind of spacing.
Background technology
jig is on lathe, to be used for fixing processing object, makes it to occupy correct position, with the device of accepting processing, cutting or detecting.Jig mainly comprises universal fixturing and special fixture, wherein, special fixture refers to and aims at certain procedure of a certain workpiece and custom-designed fixture, processing object is in cutting, in the processes such as processing, can produce vibrations, add the tension of fixture folder, easily cause damage and the wearing and tearing of workpiece, also easily cause the damage of fixture itself, existing fixture also cannot address this problem, simultaneously, existing special fixture mostly is needs manual operation to clamp processing work, can not realize automation clamps, the adjustable fixture of more existing spacing, its sensitivity is lower, can not accurately clamp, in clamping process, easily cause the wearing and tearing of processing work, cause certain loss and inconvenience.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of spacing adjustable damping special jig, the vibrations that can reduce to produce in workpiece process, thereby reduce the damage to workpiece and fixture itself, and can clamping according to required processing work size, and workpiece not easy to wear.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
The adjustable damping special jig of a kind of spacing, it is characterized in that, comprise chassis, described chassis is provided with clamp, described clamp comprises several points of clamps, described several points of clamps form disc, and clamp center is provided with circular port, for placing the workpiece that needs clamping, described circular port edge is provided with sensor, described sensor is connected with adjusting device, and described clamp is hollow structure, and inside is provided with damping device.
The adjustable damping special jig of a kind of spacing, is characterized in that, described damping device is spring.
The adjustable damping special jig of a kind of spacing, is characterized in that, described number of springs is more than 8.
The adjustable damping special jig of a kind of spacing, is characterized in that, described sensor skin is also provided with one deck pad.
The adjustable damping special jig of a kind of spacing, is characterized in that, described pad material is rubber.
The adjustable damping special jig of a kind of spacing, is characterized in that, described point of clamp number is more than 3.
The adjustable damping special jig of a kind of spacing, is characterized in that, is also provided with adjusting lever, for regulating the movement of clamp on described chassis.
Usefulness of the present utility model is: 1. the adjustable damping special jig of spacing of the present utility model is provided with damping device in clamp inside, the damage of the vibrations that produce can effectively reduce processing work time to workpiece and fixture itself, thus fixture service life extended; 2. be provided with pad in circular port outside, effectively prevent from excessively clamping the wearing and tearing that cause workpiece; 3. the adjustable damping special jig of spacing of the present utility model, detects the size of workpiece to be processed by sensor, allow clamp accurately clamp by the adjusting of adjusting device, reaches highly sensitive automation and clamps effect; 4. simplicity of design, easy to use.
Brief description of the drawings
Fig. 1 is the adjustable damping special jig of spacing of the present utility model schematic diagram.
The implication of Reference numeral in figure:
1. chassis, 2. clamp, 3. spring, 4. adjusting lever, 5. sensor, 6. adjusting device, 7. pad.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
In conjunction with Fig. 1, the adjustable damping special jig of spacing of the present utility model, comprise chassis 1, described chassis 1 is provided with clamp 2, described clamp 2 comprises 3 points of clamps, described 3 points of clamps form disc, clamp 2 centers are provided with circular port, for placing the workpiece that needs clamping, described circular port edge is provided with one deck sensor 5, described sensor 5 is connected with adjusting device 6, described clamp 2 is hollow structure, inside is provided with spring 3, described spring 3 quantity are 9, and be evenly distributed on 3 points of clamp inside, the damage of the vibrations that described spring 3 produces can effectively reduce processing work time to workpiece and fixture itself, thereby extend fixture service life, described sensor 5 skins are also provided with one deck pad 7, can effectively prevent from excessively clamping the wearing and tearing that cause workpiece, are also provided with adjusting lever 4, for regulating the movement of clamp 2 on described chassis 1.
The adjustable damping special jig of spacing of the present utility model, except said structure, its difference is, and described point of clamp number is 4, and spring 3 numbers are 8, and are evenly distributed on 4 points of clamp inside.
The adjustable damping special jig of spacing of the present utility model, when it uses:
Regulate adjusting lever 5, make the middle circular port diameter maximum of clamp 2, then cylindrical work to be processed is placed in to circular port, now, sensor 5 detects the diameter of cylindrical work, adjusting device 6 regulates, thereby controls clamp 2 to workpiece movable, to best clamped condition (diameter of circular port is compared with the little 0.5-1mm of diameter of work); Sensor 5 skins are also provided with one deck pad 7, therefore in clamping process, can effectively prevent wearing and tearing and the destruction to workpiece, simultaneously also clamping work pieces firmly, make it in process, not be prone to the situation such as rock, become flexible, and because clamp 2 inside are provided with damping device, therefore in work piece cut, boring, bruting process, can effectively reduce vibrations, thereby reduce the damage to workpiece and fixture itself.
The adjustable damping special jig of spacing of the present utility model puts into production, and on probation, respond well, is applicable to application widely.
More than show and described general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
