Description

A kind of Jia Guan mechanisms

Technical field

This utility model is related to a kind of fixture, more particularly to a kind of Jia Guan mechanisms.

Background technology

Existing Jia Guan mechanisms are typically made up of pneumatic means, i.e., by one group of cylinder（Or screw drive）Before control can body Enter, the folding of another group of cylinder control folder tank fixture, the problem that this Jia Guan mechanisms are present is when pneumatic release, entirely Folder tank fixture impulsive force is larger, and easily tank body is extruded in itself, causes deformation, and whole Jia Guan mechanisms are in motor process It is difficult to obtain higher speed of production, affects work efficiency.Additionally, some Jia Guan mechanisms directly act on folder using cam at present Tank clamp fixing plate, although can realize the speed of production of high speed, improve production efficiency, but due to pressing from both sides tank fixture pendulum angle Greatly, the unstable smoothness of whole motor process.Therefore tank fixture pendulum angle is little or level of approximation to need one kind control to press from both sides The Jia Guan mechanisms of folding.

Utility model content

In order to overcome the above-mentioned deficiencies of the prior art, this utility model provide a kind of Jia Guan mechanisms, its adopt cam and Linkage transmission, fixture pendulum angle are little, stable movement, and production efficiency is high.

This utility model solve technical scheme that its technical problem adopted for：

A kind of Jia Guan mechanisms, including frame, clamp assembly, motor and the cam with motor connection, the clamp assembly Two groups are provided with, lever in the frame, is rotatablely equipped with, the lever lower end is provided with roller, outside the outer of the cam and roller Edge is pressed into contact with, and the lever upper end is hinged with connecting rod, and the small end is hinged with two groups of movable blocks simultaneously；The movable block The left and right sides of connecting rod is distributed in, two groups of movable blocks are provided with lower axle away from one end of connecting rod, are installed with the lower axle Swing arm, is arranged axle in the swing arm, the clamp assembly upper end is set on axle, and the clamp assembly lower end is set in down On axle, two groups of clamp assemblies can be rotated around lower axle in opposite directions respectively and mutually clamp tank body.

Used as the improvement of above-mentioned technical proposal, the clamp assembly includes fixture fixed mount and linkage, the connecting rod Mechanism includes rocking arm, outside lever, connector and movable ear；The rocking arm is sleeved in lower axle, the movable ear upper and lower ends point It is not sleeved on axle and lower axle, the connector is fixed on fixture fixed mount, the connector two ends are respectively articulated with Movable ear and outside lever.

Used as the improvement of above-mentioned technical proposal, the linkage is provided with for adjusting the eccentric pin shaft of eccentric throw, described One end offers eccentric pin hole, and the rocking arm is hinged with outside lever through by way of eccentric pin hole eccentric pin shaft, institute Eccentric pin hole internal diameter is stated more than eccentric pin shaft external diameter.

Used as the improvement of above-mentioned technical proposal, the swing arm upper end is equipped with fixed block, the company of being provided between two fixed blocks Connect and draw spring.

The beneficial effects of the utility model have：

This utility model is driven using cam and linkage, and simple and reasonable, fault rate is low, debugging maintenance side Just little with energy consumption, for pneumatic mechanism, cam mechanism has timing, effectively can shorten whole shuttling movement when Between.This Jia Guan mechanisms stable action in motor process is smooth, and fixture pendulum angle is little, and folder tank fixture can carry out level of approximation Folding, therefore high-speed production can be carried out, improve work efficiency.

Description of the drawings

Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail, wherein：

Fig. 1 is the structural representation of this utility model embodiment；

Fig. 2 is the front view of Fig. 1.

Specific embodiment

Referring to Fig. 1 and Fig. 2, a kind of Jia Guan mechanisms, including frame 1, clamp assembly 2, motor and convex with motor connection Wheel 3, the clamp assembly 2 is provided with two groups, and lever 4 is rotatablely equipped with the frame 1, and 4 lower end of the lever is provided with roller 5, The outer of the cam 3 is pressed into contact with 5 outer of roller, with the rotation of cam 3, according to the different curvature radius of cam 3, thick stick Bar 4 is periodically swung up and down around frame 1；4 upper end of the lever is hinged with connecting rod 6, and 6 upper end of the connecting rod is cut with scissors simultaneously It is connected to two groups of movable blocks 7；The movable block 7 is distributed in the left and right sides of connecting rod 6, and two groups of movable blocks 7 are pacified away from one end of connecting rod 6 Equipped with lower axle 8, with the periodic wobble of lever 4, connecting rod 6 can be swung vertically, so as to drive movable block 7 to surround lower axle 8 Backswing is moved.

Swing arm 9 is installed with 8 one end of the lower axle, axle 10, the clamp assembly 2 in the swing arm 9, is arranged with Upper end is set on axle 10, and 2 lower end of the clamp assembly is set in lower axle 8, and two groups of clamp assemblies 2 difference can be under Axle 8 is opposite to be rotated and mutually clamps tank body.When connecting rod 6 is moved downward, the movable block 7 in left side drives the lower axle 8 in left side Turn clockwise, the movable block 7 on right side drives 8 rotate counterclockwise of lower axle on right side, while lower axle 7 makes axle 10 by swing arm 9 Drive the 2 opposite purpose for rotating, reaching clamping tank body of clamp assembly.

Clamp assembly 2 includes fixture fixed mount 11 and linkage 12, and the linkage 12 includes rocking arm 13, outside lever 14th, connector 15 and movable ear 16, the rocking arm 13 are sleeved in lower axle 8, and 16 upper and lower ends of movable ear are set in On upper axle 10 and lower axle 8, the connector 15 is fixed on fixture fixed mount 11, and 15 two ends of the connector are respectively articulated with Movable ear 16 and outside lever 14.The linkage 12 is provided with for adjusting the eccentric pin shaft 17 of eccentric throw, the rocking arm 13 1 End offers eccentric pin hole, and the rocking arm 13 is hinged with outside lever 14 through by way of eccentric pin hole eccentric pin shaft 17, institute Eccentric pin hole internal diameter is stated more than 17 external diameter of eccentric pin shaft, thus it is possible to vary the movement locus of rocking arm 13 and outside lever 14, while adjusting The stationarity of both motions.

By the rotation of lower axle 8, in drive, axle 10 swings back and forth around 8 periodicity of lower axle, due to being set with upper axle 10 Movable ear 16,16 one end of movable ear are hinged with connector 15, therefore also drive activity while swinging around lower axle 8 of upper axle 10 Ear 16 swings.Due to being hinged by eccentric pin shaft 17 for rocking arm 13 and outside lever 14, eccentric pin shaft 17 can finely tune whole clamping The motion of component 2, it is achieved thereby that the folding of clamp assembly 2.

The above, simply better embodiment of the present utility model, but this utility model is not limited to above-mentioned reality Example is applied, as long as which reaches technique effect of the present utility model with any same or similar means, should all belong to of the present utility model Protection domain.
