Description
Technical Field
The utility model relates to an expanding positioner in work piece.
Background
The burrs are residual scraps on the surface of the metal piece and microscopic metal particles on the surface, and need to be ground through an electric main shaft or a pneumatic main shaft in later-stage processing. Along with the development of the multi-axis mechanical arm, full-automatic operation is gradually realized in the deburring processing.
The in-process of multiaxis arm deburring needs to fix the metalwork earlier, then polishes the metalwork surface, and traditional metalwork location adopts the tight mode of surface clamp basically, has occupied most space for a great part burr can't get rid of totally.
Disclosure of Invention
An object of the utility model is to provide a stable just tight fast work piece internal expanding positioner of clamp.
The purpose of the utility model is realized through the following technical scheme: a workpiece internal expansion type positioning device comprises a positioning base, a tensioning cylinder, a cylinder connecting rod, a central positioning block and a rubber expansion sleeve; the tensioning cylinder is arranged on the lower side of the positioning base, a through hole corresponding to the telescopic rod of the tensioning cylinder is formed in the positioning base, the cylinder connecting rod is fixed at the upper end of the telescopic rod of the tensioning cylinder, and the cylinder connecting rod extends to the upper side of the positioning base from the through hole; the central positioning block is fixed at the upper end of the cylinder connecting rod, a limiting ring is arranged on the upper side of the through hole of the positioning base, the rubber expansion sleeve is sleeved on the periphery side of the cylinder connecting rod, and the central positioning block and the limiting ring respectively correspond to the upper edge and the lower edge of the rubber expansion sleeve.
Compare prior art, the utility model has the advantages of:
1. the utility model discloses a work piece is fixed to the tight mode that expands in, does not occupy the work piece surface for the operation is simple, and the burring is cleaner.
2. The utility model discloses a cylinder is direct taut for tight work piece is pressed from both sides in the expansion of the tight cover of rubber, simple structure, and is stable, and clamping speed is fast.

Description of reference numerals: the device comprises a positioning base 1, a through hole 1-1, a limiting ring 1-2, a positioning plate 1-3, a tensioning cylinder 2, a cylinder connecting rod 3, a center positioning block 4, a rubber expansion sleeve 5, a support base plate 6 and a workpiece 7.
Detailed Description
The invention is described in detail below with reference to the drawings and examples of the specification:
fig. 1 to 6 are schematic views illustrating an embodiment of a workpiece internal expanding positioning device according to the present invention.
A workpiece internal expansion type positioning device comprises a positioning base 1, a tensioning cylinder 2, a cylinder connecting rod 3, a central positioning block 4 and a rubber expansion sleeve 5;
the tensioning cylinder 2 is arranged on the lower side of the positioning base 1, a through hole 1-1 corresponding to the telescopic rod of the tensioning cylinder 2 is formed in the positioning base 1, the cylinder connecting rod 3 is fixed at the upper end of the telescopic rod of the tensioning cylinder 2, and the cylinder connecting rod 3 extends to the upper side of the positioning base 1 from the through hole 1-1;
the central positioning block 4 is fixed at the upper end of the cylinder connecting rod 3, the limiting ring 1-2 is arranged on the upper side of the through hole 1-1 of the positioning base 1, the rubber expansion sleeve 5 is sleeved on the periphery of the cylinder connecting rod 3, and the central positioning block 4 and the limiting ring 1-2 are respectively corresponding to the upper edge and the lower edge of the rubber expansion sleeve 5.
The upper edge of the rubber expansion sleeve 5 is fixed at the bottom of the central positioning block 4.
The cylinder connecting rod 3 is cylindrical, and the peripheral wall of the cylinder connecting rod 3 is connected to the inner ring of the limiting ring 1-2 in a sliding mode.
The lower side of the tensioning cylinder 2 is provided with a supporting bottom plate 6.
The upper side of the positioning base 1 is also provided with positioning plates 1-3.
The working principle of the utility model is as follows:
in an initial state, the tensioning cylinder 2 extends out, the central positioning block 4 drives the rubber expansion sleeve 5 to move upwards, and the rubber expansion sleeve 5 is attached to the outer peripheral wall of the cylinder connecting rod 3;
sleeving a workpiece on the outer peripheral side of the cylinder connecting rod 3, and accurately positioning through the positioning plates 1-3;
after positioning is finished, the tensioning cylinder 2 contracts downwards, the central positioning block 4 drives the rubber expansion sleeve 5 to move downwards, the lower edge of the rubber expansion sleeve 5 contacts with the limiting rings 1-2, the rubber expansion sleeve 5 continues to move downwards to be extruded, the middle part of the rubber expansion sleeve expands outwards, the inner wall of a workpiece is locked, and the workpiece is fixed;
after the deburring is accomplished, taut cylinder 2 upwards stretches out, and the work piece can easily be takied away to the tight cover 5 reconversion that expands of rubber.
