Abstract
The utility model discloses a circular mold drilling clamp, which comprises a connecting cover, a fixation bolt assembly, a replaceable centering plate, a circular mold to be processed and a three-claw chuck, wherein the circular mold to be processed is placed on the three-claw chuck for centering and positioning, the circular mold to be processed is also clamped by the replaceable centering plate and the fixation bolt assembly, a T-shaped groove corresponding to the fixation bolt assembly is disposed on the three-claw chuck, and a replaceable boss which has the same diameter with the inner hole of the circular mold to be processed is disposed on the replaceable centering plate. In comparison with the prior art, the circular mold drilling clamp in the utility model has the advantages that the coaxiality of the centerline of the circular mold to be processed and a machine tool spindle center can be ensured, and stability during processing is also increased in order to ensure processing accuracy of holes. The replaceable boss on the replaceable centering plate can be replaced in order to clamp various kinds of circular molds with different models and sizes. The circular mold drilling clamp has processing diversity.
Description
Technical field
The utility model relates to a kind of clamp for machining, particularly a kind of ring mould boring grab.
Background technology
Boring is one of modal processing mode of lathe, when lathe carries out Drilling operation to ring mould, need to is located and be clamped by fixture, so that carry out Drilling operation, position and the size of portalling of processing all will affect the quality of encircling mould.Therefore the quality of jig Design will be related to ring mould crudy and working (machining) efficiency problem, existing installation way affects the axiality at He Huanmo center, machine tool chief axis center, the vibration that encircles mould in process is also larger to the Accuracy in hole, the quality of the ring mould of producing does not often reach production requirement, the ring mould processing like this can not use, waste time and energy, and percent defective is high.
Utility model content
The utility model object is to provide a kind of ring mould boring grab for prior art defect.
The utility model adopts following scheme to achieve these goals: a kind of ring mould boring grab, comprise and connect cover 1, set bolt assembly 2, interchangeable centering plate 3, ring mould 4 to be processed, scroll chuck 5, on scroll chuck 5, be provided with the set bolt assembly 2 of a pair of symmetry, connect cover 1 below and be provided with interchangeable centering plate 3, ring mould 4 to be processed is placed on scroll chuck and carries out heart location, and by interchangeable centering plate 3 and set bolt assembly 2, ring mould 4 to be processed is clamped.
Ring mould 4 to be processed is undertaken the heart to locate by scroll chuck 5.
On scroll chuck 5, be provided with the T-slot corresponding with set bolt assembly 2.
Interchangeable centering plate 3 is provided with the replaceable boss identical with ring mould 4 diameter of bores to be processed.
The beneficial effects of the utility model:
The utility model clamps ring mould to be processed one end by scroll chuck, in addition one end by connection cover, interchangeable centering plate and set bolt assembly fix, so both can ensure the axiality at ring mould center line to be processed and machine tool chief axis center, also improved the stability of process, thereby ensure the machining accuracy in hole, and can carry out by changing replaceable boss on interchangeable centering plate the ring mould of the various different model sizes of clamping, there is processing diversity.
