Abstract
The utility model provides an eccentric rapid clamping press plate which comprises a press plate, wherein an inward-concave cutter feed chute is formed at one end of the press plate, a connecting rod is arranged on the press rod in a passing manner, a T-shaped nut is connected to the lower end of the connecting rod, an eccentric semicircular key is connected to the upper end of the connecting rod, the lower end surface of the semicircular key is in contact with the press plate, and a handle is in threaded connection with the semicircular key. The utility model has the benefits as follows: (1) during the clamping, a work piece can be rapidly clamped and locked by the friction angle at the contact area of the press plate and the semicircular key, so as to prevent the work piece from loosening during the use process; and (2) the clamping effect of the work piece and the press plate is achieved without need of threads, which avoids the wear damage of threads and increase the service life of the connecting rod.
Description
Technical field
The utility model relates to a kind of centering type and clamps pressing plate fast.
Background technology
Pincers worker is on drilling machine during machining hole, after the accurate positioning, with the pressing plate 1 ' location that locked, again with drill bit 5 ' boring processing parts 2 ' (see figure 1), but this reinforcing is to use bolt 3 ' come in addition fastening, make efficient not high, and after repeatedly using, bolt 3 ' in hex nut 4 ' locate, can produce distortion, last rounded state causes spanner to skid and can't be wrenched; And screw thread and hex nut 4 ' repeatedly interlock under, also cause thread abrasion and mashed tooth, cause and can't lock, service life is not long.
Summary of the invention
For solving the problem that existing of present institute use pressing plate is easy to wear, the life-span is short, the utility model provides a kind of centering type not easy to wear, that the life-span is long to clamp pressing plate fast.
The technical solution of the utility model:
A kind of centering type clamps pressing plate fast, comprise pressing plate, one end of described pressing plate has indent feed groove, it is characterized in that: be equipped with connecting rod on the described pressing plate, the lower end of described connecting rod is connected with T type nut, its upper end is connected with the woodruff key of an off-centre, and the lower surface of described woodruff key is connected with the pressing plate contact, and handle has been threaded on the described woodruff key.
Further, described woodruff key is connected with connecting rod by pivot pin.
Use of the present utility model: in processing during with a collection of gauge thickness identical materials, centering type described in the utility model is clamped pressing plate fast in elder generation and workpiece carries out initial adjustment, its objective is in order to control certain distance well, with in order to satisfy the spacing of woodruff key, can just can play effect that friction compresses like this by the eccentric throw of woodruff key.And regulate distance between them, as long as control the length of thread engagement of connecting rod and T type nut well.After the length of thread engagement of connecting rod and T type nut was adjusted, handle was down pressed, pressing plate under the effect of woodruff key angle of friction, the self-locking clamping platen, simultaneously, the workpiece under the pressing plate is also stressed to be compressed, when boring finishes, pushing handle up, workpiece just unclamps, and can take away.
Effect intentionally of the present utility model:
(1) when clamping, clamping work pieces fast, and utilize the angle of friction of pressing plate and woodruff key contact position to lock, in use, can not become flexible workpiece;
(2) because their clamping place is not to be undertaken by the locking of screw thread, also just avoided the wearing and tearing of screw thread, the service life of connecting rod is just long.

The specific embodiment
Referring to Fig. 2-3, a kind of centering type clamps pressing plate fast, comprise pressing plate 1, one end of described pressing plate 1 has indent feed groove, be equipped with connecting rod 2 on the described pressing plate 1, the lower end of described connecting rod 2 is connected with T type nut 3, and its upper end is connected with the woodruff key 4 of an off-centre, the lower surface of described woodruff key 4 is connected with pressing plate 1 contact, and handle 5 has been threaded on the described woodruff key 4.
Described woodruff key 4 is connected with connecting rod 2 by pivot pin 6.
Use of the present utility model: in processing during with a collection of gauge thickness identical materials, centering type described in the utility model is clamped pressing plate fast in elder generation and workpiece 7 carries out initial adjustment, see Fig. 5, its objective is in order to control certain distance well, with in order to satisfy the spacing of woodruff key 4, can just can play effect that friction compresses like this by the eccentric throw of woodruff key 4.And regulate distance between them, as long as control the length of thread engagement of connecting rod 2 and T type nut 3 well.After connecting rod 2 was adjusted with the length of thread engagement of T type nut 3, handle 5 was down pressed, pressing plate 1 under the effect of woodruff key 4 angle of frictions, self-locking clamping platen 1, simultaneously, the workpiece 7 under the pressing plate 1 is also stressed to be compressed, when boring finishes, up pushing handle 5, and workpiece 7 just unclamps, and can take away.
The described content of this specification embodiment only is enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
