Embodiment
In order that one of ordinary skill in the art is better understood on technical scheme, below in conjunction with the accompanying drawings and
Embodiment is further described to technical scheme.
Set what is be parallel to each other by two in Automatic-clamping machine shown in 1-4, including frame 1 referring to the drawings, the frame 1
The base 2 that crossbeam is constituted, described one end of base 2 sets fixed clamp system, and the other end sets movable clamping mechanism, institute
Stating movable clamping mechanism includes square fixed mount 3 and movable stand 4, and the movable stand 4 is slided with the square fixed mount 3 to be connected
Connect, hydraulic force mechanism is provided between the square fixed mount 3 and the movable stand 4, and the movable stand 4 is described square solid
Determine to move horizontally on frame 3, the hydraulic force mechanism is hydraulic jack 21, hydraulic jack 21 is actually made by hydraulic pressure stand control
During, two Automatic-clamping machines of a hydraulic pressure stand control are operated simultaneously, operating efficiency are improved, in the side of the base 2
Face is additionally provided with positioning clamping body.
In the present invention, the movable stand 4 includes upper mobile bar 5, lower mobile bar 6 and clamping plate 7, the upper mobile bar
5 on the front and back sides of both lower mobile bars 6 with being equipped with semicircle sliding block 8, mobile bar 5 and the lower movement on described
The end of bar 6 is equipped with limited block 11, and the clamping plate 7 is magnetic clamping plate 7, and sliding groove is provided with the square fixed mount 3
9, the sliding groove 9 is interior provided with the chute 10 being engaged with the semicircle sliding block 8;The upper mobile bar 5 of movable stand 4, lower movement
Bar 6 is to realize what left and right horizontal was moved through the support of square fixed mount 3, the movement of the invention in order to reduce movable stand 4
During between square fixed mount 3 frictional force, therefore be respectively provided with semicircle sliding block in the side of upper mobile bar 5 and lower mobile bar 6
8, semicircle sliding block 8 is engaged with the chute 10 in sliding groove 9, and semicircle sliding block 8 is just moved in chute 10 in moving process
It is dynamic, because the frictional force of rounded face is small, so enable to mobile bar 5 and lower mobile bar 6 to be subjected in moving process smaller
Frictional force, make movement more unobstructed, and the service life of movable stand 4 can also be extended.
In the present invention, the fixed clamp system includes clamping seats 12, bearing 13 and locating shaft 14, the positioning
Axle 14 is vertically fixed on the clamping seats 12, and the behind of clamping seats 12 also sets up sinker 22, it is ensured that the tightness of clamping seats 12,
The upper and lower ends of locating shaft 14 are respectively provided with socket one on the bearing 13, the locating shaft 14 and enclose magnetic location circle 15, described
Magnetic location circle 15 and the magnetic clamping plate 7 are attracting;Locating shaft 14 is vertically connected between the top and bottom of clamping seats 12, and
Connected respectively by bearing 13 between the upper end of locating shaft 14, lower end and clamping seats 12, the purpose for setting bearing 13 is the energy of bearing 13
Cylinder thrust effect under remain intact, the present invention in by the attracting principle of magnetic, in the moving process of movable stand 4 with away from
From diminution, the dynamics attracting with magnetic clamping plate 7 of magnetic location circle 15 be bigger, and so auxiliary improves clamping effect.
In the present invention, the positioning clamping body includes support base 16, air cylinder group 17 and locator 18, the support
Seat 16 is arranged on the base 2 wherein one side, and the air cylinder group 17 is set on the support base 16, the air cylinder group 17
Locator 18 described in driving end integrally connected, the locator 18 is the square structure of a side opening, in the locator 18
It is additionally provided with circular neck 19, the circular neck 19 and anti-skid washer 20 is set;Although folder can be improved by hydraulic jack 21
Tight effect, but the stability of movable stand 4 it cannot be guaranteed that, therefore the present invention devises positioning clamping body, when movable stand 4 in place
Afterwards, air cylinder group 17 is opened, promotes positioning to move forward, drives circular neck 19 to be stuck in lower mobile bar 6, the shape of circular neck 19
Shape and the side view of lower mobile bar 6 match.
Structure of the present invention need not set fastening bolt or drawing handle, whole clamping process automation, and clamp
Effect is good, in use, adjusting the position of movable stand 4 according to workpiece size, upper mobile bar 5 and lower mobile bar 6 are utilized during adjustment
Slide and hydraulic jack 21 it is flexible, move left and right movable stand 4, in place after, locked, completed by locator card clamping body
Afterwards, it is automatic to unclamp.
