Abstract
The utility model provides a hold-down mechanism, which comprises a bottom plate, a cam, a handle, a workpiece mounting portion, supports and two pressing plates. The cam is pivotally mounted on the bottom plate; two cam portions in end-to-end ring joint are arranged on the circumferential surface of the cam; the distance from the starting point to the final point of each cam portion and the distance from each cam portion to a pivotal axis of the cam are increased gradually; the handle is connected with the cam; the workpiece mounting portion is arranged above the dam; the supports are respectively arranged on two sides of the cam; the two pressing plates are respectively mounted on the two supports; the middles of the pressing plates are pivotally connected with the supports by the aid of pivots; one of two ends of each pressing plate is a pressing end for pressing a workpiece; the other end of each pressing plate is a pressed end; and two pressed ends of the two pressing plates are respectively pressed by the two cam portions. Compared with the prior art, the hold-down mechanism has the advantages that workpieces are held down by employing the cam to press the pivotal pressing plates, and assembly and disassembly are convenient and rapid.
Description
Technical field
The utility model relates to a kind of hold-down mechanism, relates in particular to a kind of cam pressing mechanism.
Background technology
In field of machining, often need workpiece to reprocess work such as detection after fixing.Under these occasions, it is fixing reliably to require workpiece to be stabilized.Therefore, need to adopt device fixation workpieces such as anchor clamps, yet existing anchor clamps are the regulating step more complicated often, needs the long period could fix what a workpiece, the back dismounting workpiece that disposes needs a period of time again.This has reduced the treatment effeciency of workpiece.
The utility model content
At the deficiencies in the prior art, the utility model purpose is to provide a kind of hold-down mechanism of the workpiece of dismounting quick and precisely.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that
A kind of hold-down mechanism comprises: base plate; Can pivot is installed on cam on the base plate, comprises the cam portions of two head and the tail articulatings on the periphery of described cam, and each cam portion becomes big by its starting point to its terminal point gradually apart from the distance of cam's pivot; The handle that connects cam; Be located at cam top workpiece installation portion; Be located at the bearing of cam both sides respectively; Be installed on two pressing plates of two bearings respectively, the middle part of described pressing plate is by the pivotable connection bearing of pivot, one end at its two ends is the pressure side of compressing workpiece, and the other end is the pressed side, and two pressed sides of two pressing plates are optionally oppressed by described two cam portions respectively.
Further, the pivot axis of described cam is perpendicular to base plate, and the pivot of described pressing plate is parallel to base plate.
Further, on the pressure side of described pressing plate block rubber is installed.
The limited block of restriction handle rotating range further, is installed on the described base plate.
Further, described handle is positioned at the junction of two cam portions of cam.
Further, be provided with between described pressing plate and the bearing towards back-moving spring away from workpiece direction compressing pressing plate.
Further, described floor below is provided with leg.
Further, the outer peripheral face shape convex-concave of the shape of the pressure side of described pressing plate and workpiece matches.
Further, the starting point of a described cam portion is in abutting connection with the terminal point of another cam portion.
Compared with prior art, the beneficial effects of the utility model are: adopt cam to oppress pivotable pressing plates workpiece, and convenient to disassembly.

The specific embodiment
Mode with example describes the specific embodiment of the present utility model with reference to the accompanying drawings.
See figures.1.and.2, the hold-down mechanism of present embodiment comprises a base plate 1, and the below of base plate 1 is provided with leg base plate 1 is supported in suitable operation height.A cam 3 is installed on the base plate, and cam 3 can be with respect to base plate 1 around self longitudinal axis pivot, and this longitudinal axis is perpendicular to base plate 1.The cam portions that comprise two head and the tail articulatings on the periphery of cam 3, each cam portion becomes big by its starting point to its terminal point gradually apart from the distance of the pivotal axis of cam 3.The starting point of a cam portion is in abutting connection with the terminal point of another cam portion.Handle 5 is installed on the cam, and handle 5 is positioned at the head and the tail coupling part of two cam portions.Handle 5 is used to drive the cam rotation.The limited block 9 of restriction handle 5 rotating ranges is installed on the base plate 1, and limited block 9 is positioned at the part of keeping right of the rotation formation of cam 3.Cam 3 tops are provided with the workpiece installation portion, and workpiece 15 is installed on the workpiece installation portion.
On the base plate 1, the both sides of cam 3 are respectively equipped with a bearing 7, and bearing 7 tops are connected with two pressing plates 11 respectively by pivot structure.Pivot is positioned at the middle part of pressing plate 11.One end at the two ends of pressing plate 11 is the pressure side of compressing workpiece, and the other end is the pressed side, and two pressed sides of two pressing plates are optionally oppressed by described two cam portions respectively.Block rubber 13 is installed on the pressure side of described pressing plate 11, and the outer peripheral face shape convex-concave of the shape of pressure side and workpiece 15 matches.
Be provided with between described pressing plate 11 and the bearing 7 towards back-moving spring away from workpiece 15 directions compressing pressing plate 11.This back-moving spring can push away workpiece 15 with the pressure side when cam 3 unclamps pressing plate 11, be convenient to dismounting.
By above-mentioned structure, when needs are installed workpiece 15, only need workpiece is placed on the cam 3, pull handle 5 then from left to right, can be by the diameter of two cam portions bigger part pushes away the oppressed direction of looking away from cam 3 and workpiece 15 of pressing plate 11, and then make that the pressure side of pivotal axis opposite side is close to the direction of workpiece 15, workpiece pressing 15.When needs unclamp workpiece 15, only need pull handle 5 round about and get final product simple and fast.
Although be the example purpose, preferred implementation of the present utility model is disclosed, but those of ordinary skill in the art will recognize that under situation about not breaking away from by the disclosed scope and spirit of the present utility model of appending claims, various improvement, increase and replacement are possible.
