Abstract
The invention relates to a six-bar hinge clamping mechanism, which comprises a fixed power source, a first transmission bar, a second transmission bar, a third transmission bar, a clamping head, a first pivot and a second pivot, wherein the middle part of the first transmission bar is propped against the first pivot and is in transmission connection with the power source; the first transmission bar can rotate anticlockwise through the power source and the first pivot; the first transmission bar is in transmission connection with the third transmission bar through the second transmission bar; the third transmission bar is connected with the clamping head through a hinge; and the hinge is fixed on the second pivot. Compared with the prior art, the six-bar hinge clamping mechanism has the advantages of simple structure and convenient use, changes the layout form of an oil cylinder (or air cylinder) of the conventional six-bar hinge clamping mechanism, can make up the limitation on the aspects of installation or use due to insufficient swing space of the oil cylinder (or air cylinder) by changing a swing cylinder into a fixed cylinder, and has totally same clamping function and action as the conventional mechanism.
Description
Technical field
The present invention relates to clamping device, particularly relate to a kind of six-bar hinge clamping mechanism.
Background technology
Any machine components will be processed on Metal Cutting Machine Tool, all must be clamped, and be moved to prevent workpiece in process, to be subjected to the effect of external force such as cutting force, thereby destroy the tram of workpiece on lathe.
Clamping device is exactly to be used for the device of clamping work pieces on lathe.
Clamping device generally can be divided into two parts: power source and running part.Power source is used to produce clamping force, and that power source can come from is pneumatic, hydraulic pressure and electric power etc., also can come from manpower.Running part is that motive power is converted into clamping force, the mechanism that realizes clamping action and clamp effect.
Hinge clamping mechanism is a kind of clamp mechanism that extensively adopts aborning, and it is simple in structure, and force increasing ratio is big, and can change the direction of active force, therefore, is being in the motive occasion with hydraulic pressure or air pressure, most hinge clamping mechanisms that adopt.
Fig. 1 is the kinematic sketch of six-bar hinge clamping mechanism common in a kind of produce.The operation principle of this mechanism is: inject hydraulic oil (or compressed air) in the left chamber of oscillating oil cylinder 1 ' (or cylinder), piston rod 10 ' is gone up produced a thrust P, piston rod 10 ' moves right, and then carry out bar 11 and rotate counterclockwise, thus clamping work pieces 9.
Summary of the invention
Technical problem to be solved by this invention is exactly to provide a kind of six-bar hinge clamping mechanism for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: a kind of six-bar hinge clamping mechanism, it is characterized in that, comprise fixing power source, first drive link, second drive link, the 3rd drive link, clamping head, first fulcrum and second fulcrum, the middle part of described first drive link and first fulcrum offset, and be in transmission connection with power source, first drive link can rotate by the power source and first fulcrum, described first drive link is in transmission connection by second drive link and the 3rd drive link, the 3rd drive link is connected with clamping head by hinge, and described hinges fixing is on second fulcrum.
Described fixing power source adopts fixed oil cylinder or fixing cylinder, and its piston rod and first drive link are in transmission connection.
Described first fulcrum comprises supporter and support bar, and an end of described support bar is fixed on the supporter, and the middle part of the other end and first drive link offsets.
Compared with prior art, mechanism of the present invention has changed the distribution form of the oil cylinder (or cylinder) of existing six-bar hinge clamping mechanism, change oscillating cylinder into stationary cylinder, can remedy the installation that brings because of oil cylinder (or cylinder) swing insufficient space or the restriction of use aspect, and that it clamps function and action and existing mechanism is identical; This mechanism selects hinge clamping mechanism novel, function admirable for machinery manufacturing industry selection is provided, and also the transformation for old mechanism provides favourable approach.
Description of drawings
Fig. 1 is the schematic diagram of existing hinge clamping mechanism;
Fig. 2 is a structural scheme of mechanism of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 2, a kind of six-bar hinge clamping mechanism, comprise fixing power source 1, first drive link 2, second drive link 3, the 3rd drive link 4, clamping head 5, first fulcrum 6 and second fulcrum 7, the middle part of described first drive link 2 and first fulcrum 6 offset, and be in transmission connection with power source 1, first drive link 2 can rotate by the power source 1 and first fulcrum 6, described first drive link 2 is in transmission connection by second drive link 3 and the 3rd drive link 4, the 3rd drive link 4 is connected with clamping head 5 by hinge 8, and described hinge 8 is fixed on second fulcrum 7.
Described fixing power source 1 adopts fixed oil cylinder or fixing cylinder, and its piston rod 10 and first drive link 2 are in transmission connection; Described first fulcrum 6 comprises supporter 60 and support bar 61, and an end of described support bar 61 is fixed on the supporter, and the middle part of the other end and first drive link 2 offsets.
Operation principle is: inject hydraulic oil (or compressed air) in the left chamber of oil cylinder 1 (or cylinder), make and produce a thrust P on the piston rod 10, promoting piston rod 10 moves right, first drive link 2 promotes second drive link 3 and up moves, the 3rd drive link 4 is rotated counterclockwise around hinge 8, drive clamping head 5 and rotate counterclockwise, thus workpiece pressing 9.When injecting hydraulic oil (or compressed air) in the right chamber, piston rod 10 is toward moving left, and first drive link 2 drives second drive link 3 and down moves, and the 3rd drive link 4 is clockwise rotated around hinge, thereby make clamping head 5 unclamp workpiece 9.
