Abstract

The utility model discloses an expansion collet, designed for an expansion collet which can be directly used for artistic production without repeated material-mixing, and regulated in multi-angle discretionarily. It includes a short cylindrical upper plywood, an annular conterminous base and a cylindrical under provided between them. a blind hole is provided between the center of conterminous base and the lower plane of the upper plywood, the figure of the blind hole near the top plane of upper plywood is coniform, a wedge groove up to the bottom of the supporting rack is provided on the plane of upper plywood, said upper plywood, the conterminous base and the supporting rack are integrated of plastic, the number of said wedge grooves is more than three and the wedge grooves locate in the center or around the center of upper plywood. The expansion collet of above related structure can machining the mirror frame, spectacles frame nose frame and other components conveniently.

Description

The swelling chuck

Technical field

The utility model relates to a kind of parts of sheet material mirror holder fancy machine, particularly a kind of swelling chuck.

Background technology

The swelling chuck be sheet material mirror holder fancy machine commonly used parts, adopted high-carbon steel through processing mostly in the past, series of process such as quenching, cutting are made, the cost of manufacture height is time-consuming.Needs ingredient repeatedly when being used to manufacture, angular adjustment is bad, and practicality is lower.

The utility model content

For overcoming above-mentioned defective, the utility model purpose is to provide a kind of production that directly acts on fancy, need not ingredient repeatedly, can any swelling chuck of regulating of multi-angle.

For achieving the above object, swelling chuck of the present utility model, comprise the short cylindrical shape train wheel bridge, annular connects base and is located at train wheel bridge and the cylindrical support frame that is connected between the base, the central straight of this connection base to the lower plane of train wheel bridge is shaped on a blind hole, the plane is tapered on the nearly train wheel bridge of this blind hole, on the train wheel bridge plane, have draw-in groove until the bracing frame bottom, described train wheel bridge, connect base and bracing frame and adopt integrally moulded making, described draw-in groove is at least three, these at least three draw-in grooves are at the intersection point of train wheel bridge or be positioned at the center of train wheel bridge, or the center of departing from train wheel bridge.

Adopt the swelling chuck of said structure,,, can directly act on the production of fancy so need not ingredient repeatedly because train wheel bridge, connection base and bracing frame adopt integrally moulded making.Moreover, draw-in groove is made as at least three, and they are at the intersection point of train wheel bridge or be positioned at the center of train wheel bridge, or the center of departing from train wheel bridge, the needs of can multi-angle when having satisfied the manufacturing spectacle parts regulating arbitrarily.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

As Fig. 1-shown in Figure 8, swelling chuck of the present utility model, comprise short cylindrical shape train wheel bridge 1, annular connects base 3 and is located at train wheel bridge 1 and the cylindrical support frame 2 that is connected between the base 3, the central straight of this connection base 3 to the lower plane of train wheel bridge 1 is shaped on a blind hole 4, the plane is tapered on these blind hole 4 nearly train wheel bridges 1, on train wheel bridge 1 plane, have draw-in groove 5 until bracing frame 2 bottoms, for convenience of mirror leg to glasses, the mirror pin, mirror holder, picture frame, the processing of parts such as nose frame, with train wheel bridge 1, connect base 3 and integrally moulded the making of bracing frame 2 employings, and draw-in groove 5 is made as at least three, these at least three draw-in grooves 5 are at the intersection point of train wheel bridge 1 or be positioned at the center of train wheel bridge 1, or the center of departing from train wheel bridge 1.The swelling chuck of said structure because train wheel bridge 1, connection base 3 and bracing frame 2 adopt integrally moulded making, so need not ingredient repeatedly, can directly act on the production of fancy.Moreover, draw-in groove 5 is made as at least three, and they are at the intersection point of train wheel bridge 1 or be positioned at the center of train wheel bridge 1, or the center of departing from train wheel bridge 1, the needs of can multi-angle when having satisfied the manufacturing spectacle parts regulating arbitrarily.

As shown in Figure 1 and Figure 2, as the utility model preferred embodiment, draw-in groove 5 is made as three, these three draw-in grooves 5 are positioned at the center of train wheel bridge 1 at the intersection point of train wheel bridge 1.

As shown in Figure 3, Figure 4, as the utility model second embodiment, draw-in groove 5 is made as three, these three draw-in grooves 5 depart from the center of train wheel bridge 1 at the intersection point of train wheel bridge 1.

As Fig. 5, shown in Figure 6, as the utility model the 3rd embodiment, draw-in groove 5 is made as six, these six draw-in grooves 5 are positioned at the center of train wheel bridge 1 at the intersection point of train wheel bridge 1.

As Fig. 7, shown in Figure 8, as the utility model the 4th embodiment, draw-in groove 5 is made as six, these six draw-in grooves 5 depart from the center of train wheel bridge 1 at the intersection point of train wheel bridge 1.
