Abstract
The invention discloses a concentric circle telescopic ring, and relates to a telescopic ring. The telescopic ring consists of a plurality of supporting rods, the middle parts of two supporting rods are connected through a pin shaft to form an X shape, and two ends of the supporting rods are connected end to end through pin shafts to form a ring shape; the supporting rods can be straight rods, and can also be <-shaped rods; all the supporting rods can rotate around the pin shafts; and the supporting rods are made of hard material. The telescopic ring can realize fixed circle center and synchronous telescopic change of diameters, can improve the precision and the production efficiency in the processing of specifying the diameter or the inside diameter of an object, and is convenient to use.
Description
Technical field
The present invention relates to a kind of expansion ring, specifically a kind of concentric circles expansion ring.
Background technology
When at present some need the object of diameter change in processing, often need its internal diameter of standard or external diameter, and currently used equipment is also failed the device realizing keeping concentric and can stretch arbitrarily on same diameter, machining accuracy is not high, and production efficiency is low.
Summary of the invention
The object of the present invention is to provide a kind of concentric circles expansion ring, address the above problem.
The technical solution adopted for the present invention to solve the technical problems is: the concentric circles expansion ring, it is characterized in that described expansion ring is made of a plurality of support bars, the middle part of two support bars connects by bearing pin, form the X type, the two ends of support bar are connected to form ring-type from beginning to end by bearing pin again; Described support bar can be straight-bar, also can adopt＜type bar; Described support bar all can rotate around bearing pin; Described support bar is a hard material.
The invention has the beneficial effects as follows: can realize that the center of circle fixes, but the diameter synchronization telescope change, in the processing that needs standard article diameters or internal diameter, can improve precision and production efficiency, be convenient to use.
Description of drawings
Fig. 1 is a structural representation of the present invention,
Fig. 2 is a contraction structure schematic diagram of the present invention.
Among the figure: 1 support bar, 2 bearing pins.
The specific embodiment
As Fig. 1, shown in Figure 2, the concentric circles expansion ring, described expansion ring is made of a plurality of support bars 1, and the middle part of two support bars 1 connects by bearing pin 2, forms the X type, and the two ends of support bar 1 are connected to form ring-type by bearing pin 2 head and the tail again; Described support bar 1 can be straight-bar, also can adopt＜type bar; Described support bar 1 all can be around bearing pin 2 rotations; Described support bar 1 is a hard material.
The present invention can greatly do the concentric stretching motion in the scope, and inside and outside angular distance strengthens during contraction, and single support bar 1 is near concentrically ringed radius; The extension inside and outside angular distance that comes dwindles, and the support bar 1 of all connections is near concentrically ringed external diameter, and the expansion ring angle number ratio of multi-expansion more is big more.Install a linear pattern device sidewards additional at the top at interior angle or exterior angle, can guarantee in the telescopic process all the time and the inside and outside circle tangent; Between the top at interior angle or exterior angle, connect the flexible arc object, can make positive circular shape concentric retractor device.
Claims (4)
