Abstract
The utility model provides a centering fixture, includes left chuck (4) and right chuck (5), left side chuck (4) and right chuck (5) and a spout (2) sliding connection still include a hydraulic rod (3), its push rod (31) and right chuck (4) fixed connection, push rod (31) the front end and one second pneumatic cylinder (32) of hydraulic rod (3) are connected, and these second pneumatic cylinder (32) package is connected with gyration half month hydraulic pressure pipe (33), and the other end and one straight tube pneumatic cylinder (34) of these half month hydraulic pressure pipe (33) are connected, one second push rod (35) of sliding connection in these straight tube pneumatic cylinder (34), and these second push rod (35) and left chuck (4) fixed connection, second pneumatic cylinder (32) pipe diameter is the same with hydraulic rod's (3) pneumatic cylinder pipe diameter. Use the hydraulic pressure simultaneous control to control chuck work, it is accurate to feel relieved, and durable.
Description
Technical field
The utility model relates to a kind of centralizer.
Background technology
Now current weld clamp fixture many employings synchronising hinge structure, two claws slide at line slide rail, realize synchronous clamping by synchronising hinge.In order to ensure that two claws are synchronous, the requirement on machining accuracy of two synchronising hinges is very high.Fixture is when clamping in addition, and synchronising hinge relative centre axle has rotation, and along with the passing of service time, on hinge, the centre-to-centre spacing in two holes just there occurs change, causes two claw synchronization accuracies to decline, centering and inaccurate.And the equal utility machine of centralizer rotates mostly, as gear, slide block etc., long existing wearing and tearing service time one, centering precision all can decline.
Summary of the invention
The purpose of this utility model provides a kind of long-time use still can keep high-precision centralizer.
For achieving the above object, a kind of centralizer of the utility model, comprise left chuck and right chuck, described left chuck is connected with a slide with right chuck, also comprise a hydraulic push rod, its push rod is fixedly connected with right chuck, it is characterized in that, the push rod front end of described hydraulic push rod is connected with one second hydraulic cylinder, this second hydraulic cylinder is connected with half circular winding pipe, the other end of this semicircle bend pipe is connected with a straight tube hydraulic cylinder, be slidably connected in this straight tube hydraulic cylinder one second push rod, this second push rod is fixedly connected with left chuck, described second hydraulic cylinder caliber is identical with the hydraulic cylinder caliber of hydraulic push rod.
By being extended by push rod, be connected with another second hydraulic cylinder, when hydraulic push rod works, push rod travels forward, and is released by the hydraulic oil in isopyknic second hydraulic cylinder, promotes the second push rod and stretch out, thus realizes being synchronized with the movement.Worked by hydraulic drive chuck, decrease the problem that centering that mechanical wear brings is inaccurate to greatest extent, fixture is used for a long time and still can keep higher centering precision.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Fig. 2 is left chuck and right chuck left view.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, comprise left chuck 4 and right chuck 5, described left chuck 4 and right chuck 5 and a chute 2 are slidably connected, also comprise a hydraulic push rod 3, its push rod 31 is fixedly connected with right chuck 4, it is characterized in that, push rod 31 front end of described hydraulic push rod 3 is connected with one second hydraulic cylinder 32, this second hydraulic cylinder 32 is connected with half circular winding pipe 33, the other end of this semicircle bend pipe 33 is connected with a straight tube hydraulic cylinder 34, be slidably connected in this straight tube hydraulic cylinder 34 one second push rod 35, this second push rod 35 is fixedly connected with left chuck 4, described second hydraulic cylinder 32 caliber is identical with the hydraulic cylinder caliber of hydraulic push rod 3.Described left chuck 4 lower end has an extension to be left chuck tail 41, and described right chuck 5 lower end has an extension to be right chuck tail 51, and described left chuck tail 41 and right chuck tail 51 are all slidably connected with a chute 1.
As shown in Figure 2, the axial width of left chuck tail 41 is less than left chuck, equally, the thickness of right chuck tail is less than right chuck, and left chuck tail is fixed on the left end of left chuck, and right chuck tail is fixed on the right-hand member of right chuck, when two chucks move to centre, two chuck tails can not contact.
Object is put in the middle of two chucks during use, open hydraulic push rod 3 and can realize centering clamping.
