Abstract

The utility model discloses a pair of hydraulic flat tongs which comprises a tongs seat, a sliding seat, a fixed jaw, a movable jaw and an adjusting screw rod, wherein the fixed jaw is directly fixed on the tongs seat; the movable jaw is slidably connected with the tongs seat through the sliding seat driven to horizontally move by the adjusting screw rod; the tail end of the adjusting screw rod is connected with the piston rod of a hydraulic oil cylinder. In conclusion, the hydraulic flat tongs disclosed by the utility model provides the preset thrust used for clamping and locking a workpiece all the time in the clamping process of a gad tongs and can effectively prevent the workpiece from being loosened and reduce the phenomenon that the workpiece is damaged by being clamped, thereby enhancing the machining accuracy of the workpiece.

Description

Hydraulic flat tongs
Technical field
The utility model relates to a kind of universal fixturing flat-nose pliers in a kind of machine tool accessories, specifically a kind of hydraulic flat tongs.
Technical background
Bottom a kind of universal fixturing in the flat-nose pliers machine tool accessories, flat-nose pliers, keyway is arranged, it directly is bumped in the keyway of platen by flat key, then fastens flat-nose pliers with pressing plate, usually all is mounted on machining center, drilling machine, milling machine, surface grinding machine press.
The flat-nose pliers structure generally is comprised of clamp block, slide, regular jaw, moving jaw and adjusting screw(rod), wherein regular jaw directly is fixed on clamp block, moving jaw is slidably connected by slide and clamp block, in use, parallel sliding by the relative clamp block of slide, drive the first transaction of a day's business and the closure of jaws between moving jaw and regular jaw, realize workpiece unclamp blanking and clamping and positioning and machine tool accessories.
At this, parallel sliding with upper saddle realizes by manual adjustment adjusting screw(rod), and there is very large problem in this manual adjustment mode, the bad assurance of dynamics when adjusting screw(rod) is adjusted on the one hand, cause the feeding of slide block very not steady, sometimes fast and sometimes slow phenomenon occurs, and then make the clamping force of moving jaw and regular jaw unstable, workpiece is easy to produce damage because clamping is hit by force unbalance; On the other hand, after Workpiece clamping, the locking of whole flat-nose pliers realizes by the screw thread self-locking of adjusting screw(rod), locking effect compares relatively poor, and in workpiece process, usually workpiece is stressed all larger and with the vibrations of high frequency, is easy to occur jaws lax and workpiece is become flexible, and has had a strong impact on the machining accuracy of workpiece; In addition, the manual adjustments mode of adjusting screw(rod), each operation can only be carried out for a flat-nose pliers, requires great effort and inefficiency, can't satisfy the needs of modernization large-scale processing.
The utility model content
For the problems referred to above, the utility model has designed a kind of hydraulic flat tongs, the clamping locking that it provides a pre-thrust to be used for workpiece in the clamping process of flat-nose pliers all the time can prevent effectively that workpiece is loosening and reduce the phenomenon generation that crushes workpiece, the machining accuracy of lifting workpieces.
For achieving the above object, the utility model is by the following technical solutions:
A kind of hydraulic flat tongs, comprise clamp block, slide, regular jaw, moving jaw and adjusting screw(rod), wherein regular jaw directly is fixed on clamp block, moving jaw is slidably connected by driving slide and the clamp block of carrying out translation by adjusting screw(rod), and it is characterized in that: described adjusting screw(rod) tail end is connected with the piston rod of a hydraulic jack.
Further, the cylinder body of above-mentioned hydraulic jack directly is fixed on clamp block by adpting flange.
The adjusting activity of the utility model adjusting screw(rod) is driven by the piston rod of hydraulic jack, can realize the push-and-pull of slide at the uniform velocity, can not affect because of the speed of speed the life-span of moving jaw, can not cause clamping force uneven because of the speed inequality simultaneously yet, can effectively reduce the damage that workpiece is caused, the depth of parallelism and perpendicularity when promoting the flat-nose pliers clamping, the machining accuracy of assurance workpiece.
In addition, at workpiece process, hydraulic jack is still in running order, and its piston rod offers the constant pre-thrust of adjusting screw(rod) one all the time, makes moving jaw firmly Workpiece clamping, prevents that effectively workpiece is loosening, ensures the machining accuracy of workpiece.
Description of drawings
Fig. 1, structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of hydraulic flat tongs, comprise clamp block 1, slide 2, regular jaw 3, moving jaw 4 and adjusting screw(rod) 5, wherein regular jaw 3 directly is fixed on clamp block 1,4 of moving jaws are slidably connected with clamp block 1 by driving by adjusting screw(rod) 5 slide 2 that carries out translation, and described adjusting screw(rod) 5 tail ends are connected with the piston rod 61 of a hydraulic jack 6.
The cylinder body 62 of described hydraulic jack 6 is installed end face and is provided with adpting flange 621, and clamp block 1 is provided with the screwed hole that matches with mounting flange 621, and cylinder body 62 adopts the mode of screw to be arranged on clamp block 1, is convenient to the installation and removal of cylinder body 62.
The adjusting activity of the utility model adjusting screw(rod) 5 is driven by the piston rod 61 of hydraulic jack 6, can realize the push-and-pull of slide 2 and moving jaw 4 at the uniform velocity, can not affect because of the speed of speed the life-span of moving jaw 4, can not cause clamping force uneven because of the speed inequality simultaneously yet, can effectively reduce the damage that workpiece is caused, the depth of parallelism and perpendicularity when promoting the flat-nose pliers clamping, the machining accuracy of assurance workpiece.
In addition, at workpiece process, hydraulic jack 6 is still in running order, its piston rod 61 offers the constant pre-thrust of adjusting screw(rod) 5 one all the time, makes moving jaw 4 firmly Workpiece clamping, and clamping force is stable, prevent that effectively workpiece is loosening, ensure the machining accuracy of workpiece.At this, in actual processing, can be according to the material size of workpiece, select different working hydraulic pressures and pre-thrust, make workpiece can access steadily permanent clamping force, can not occur that to spend the little jaws that causes lax because of chucking power, can not spend because of chucking power make greatly workpiece deformation and crush yet, effectively offset the dither phenomenon of workpiece process.
The action of above hydraulic flat tongs hydraulic jack 6 control to be realized by controller, and work in-process only needs a button just can make the flat-nose pliers clamping of one or more lathe, works laborsaving and efficient is high, can satisfy the needs of modernization large-scale processing.
The above, it is only better embodiment of the present utility model, be not that utility model is done any pro forma restriction, every foundation know-why of the present utility model still belongs in the scope of technical solutions of the utility model any simple modification made for any of the above embodiments, equivalent variations or modification.
