Abstract
Provided is a metal intertwining spacer outer ring turning groove chunk. The metal intertwining spacer outer ring turning groove chunk is composed of a three-jaw chunk and sector claws, the number of the sector claws is three, the sector claws are respectively arranged on the three claws of the three-jaw chunk, a hollow annular shape is composed of three sector claws, and the interval of the three sector claws is 8-13 millimeters; successively descending arc steps are turned on the sector claws; and the number of the descending arc steps is 10-15. The metal intertwining spacer outer ring turning groove chunk successively inward turnings required steps with different sizes on the sector claws, outer rings with various kinds of sizes can be clamped by fastening or loosing the three-jaw chunk, when the outer rings of the intertwining spacer are machined, and transformation of workpieces is reduced by enlarging the contact area between the sector claws and the workpieces. The metal intertwining spacer outer ring turning groove chunk has the advantages of being reliable in clamping and holding, flexible and light, and end surfaces do not bounce, the speed of clamping components is fast, time is greatly saved and precision of manufacturing the components of the metal intertwining spacer outer ring turning groove chunk is guaranteed.
Description
Technical field
The utility model relates to mechanical automation and makes the field, is a kind of metal wound gasket outer shroud recessing chuck specifically.
Background technology
General wound gasket outer shroud on the market is all generally through punching press, rewash launder after welding or weld all around, and according to standard-required, the wound gasket outer shroud answers anchor ring smooth, its flatness franchise should be less than 1%; Annular groove should be concentric with inside and outside circle, answers symmetrical with both ends of the surface; In the past on lathe with three-jaw or chuck processing metal wound gasket outer shroud, to want V-shaped groove of car system on 2-3 millimeter thin ring internal diameter, can't reliably clamp part at all, its torsional deformation of ambassador slightly firmly, exert oneself littlely can't reliably clamp part again, the V-shaped groove of the car system of making not in ring in the heart, difficulty is very large, can't it guarantee machining accuracy at all.
Summary of the invention
In sum, the purpose of this utility model is to provide a kind of metal wound gasket outer shroud recessing chuck.
The purpose of this utility model realizes by following technology:
A kind of metal wound gasket outer shroud recessing chuck is comprised of scroll chuck and fan-shaped pawl, and fan-shaped pawl has 3, is separately fixed on 3 pawls of scroll chuck.
Above-mentioned 3 fan-shaped pawls consist of an open circles ring-type, its gap 8 ~ 13mm.
The arc steps that above-mentioned fan-shaped pawl is got on the bus and descended successively.
Above-mentioned arc steps is 10 ~ 15.
Advantage of the present utility model and beneficial effect:
the utility model, it is simple in structure, fan-shaped at 120 three of degree, (external diameter can be determined with the maximum rotating diameter of lathe) thickness is that the 40mm steel plate is fixed on three pawls of scroll chuck, inside car is made the step of needed various sizes successively, pine or tight scroll chuck be the outer shroud of the various models of energy clamping just, it is when processing wound gasket outer shroud, increase fan-shaped pawl and workpiece contact area, reduced the distortion of workpiece, and clamping is reliable, light flexibly, end face is without beating, clamping part speed is fast, greatly save time, more can guarantee the precision of its part processing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: the fan-shaped pawl 3-of 1-scroll chuck 2-arc steps
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, a kind of metal wound gasket outer shroud recessing chuck is comprised of scroll chuck 1 and fan-shaped pawl 2, and fan-shaped pawl 2 has 3, is separately fixed on 3 pawls of scroll chuck 1; 3 fan-shaped pawls 2 consist of an open circles ring-type, its gap 8 ~ 13mm; The arc steps 3 that fan-shaped pawl 2 is got on the bus and descended successively; Arc steps 3 is 10 ~ 15.
