Description
Technical field
The utility model relates to clamping field, is specifically related to a kind of positioning fixture.
Background technology
In mechanical processing process, generally all to clamp workpiece, this is because workpiece will be subject to the External Force Actings such as cutting force, inertia force, centrifugal force in process, if do not clamp, then cannot ensure that workpiece still can keep the operating position determined under the effect of these external force, thus produce displacement.The displacement of workpiece will cause the damage of cutter and lathe, even personal injury occurs.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of positioning fixture, and this positioning fixture can carry out clamping to workpiece, makes workpiece can not produce displacement and vibration in process, avoids the damage of cutter and lathe, ensure personal safety.
The purpose of this utility model carrys out specific implementation by the following technical programs:
A kind of positioning fixture, mainly comprise base plate, cushion block, pressing plate and briquetting, described cushion block is between base plate and pressing plate and be fixed on base plate, and described briquetting is between cushion block with pressing plate and be flexibly connected with pressing plate, is provided with the first depression bar and the second depression bar between base plate and pressing plate; The bottom of described first depression bar be connected with base thread and top by bearing pin and pressing plate hinged, the bottom of described second depression bar and base plate hinged and top are locked by locking nut and pressing plate and are leaned on.
Further, be provided with boss between described second depression bar and base plate, described boss lower end is provided with the extension rod be connected with base thread, and bottom and the boss of described second depression bar are hinged.
Further, the bottom of described briquetting is provided with and keeps away barrier groove.
A kind of positioning fixture of the utility model, this positioning fixture mainly comprises base plate, cushion block, pressing plate, briquetting, the first depression bar and the second depression bar, workpiece is placed on cushion block top, briquetting is pressed on workpiece, and by adjusting lock nut by Work-sheet pressing, structure is simple, clamp operation is safe, convenient and laborsaving, workpiece can not produce displacement and vibration in process, avoids the damage of cutter and lathe, ensures personal safety.
