Abstract
The utility model relates to the technical field of mechanical press machines, in particular to a flexible connecting mechanism of a slider and a balance cylinder of the mechanical press machine. The press machine capable of flexibly connecting the slider and the balance cylinder comprises a slider support and the balance cylinder, wherein the balance cylinder comprises a piston rod, the lower end of the piston rod faces toward the slider support, the lower end of the piston rod is connected with a double-screw bolt in a threaded mode, concave ball rings and protruding ball surface flanges are sleeved outside the double-screw bolt at intervals, each protruding ball surface flange is arranged at the lower side of each concave ball ring, the lower end of each concave ball ring is matched with the upper end of each protruding ball surface flange, a shoulder is arranged inside each protruding ball surface flange, the lower end of the double-screw bolt is connected with a ball surface nut which is arranged on the shoulder, and each protruding ball surface flange is connected with the slider support through at least two internal hexagon cylindrical head bolts. The press machine capable of flexibly connecting the slider and the balance cylinder has the advantages of being not high in requirements on processing accuracy of reference for installation of the piston rod of the balance cylinder and the slider, and capable of having a certain unbalance loading resistant ability, improving the process accuracy of the press machine and prolonging service life of the press machine.
Description
Technical field
The utility model relates to the punching machine technical field, relates in particular to a kind of slide block of punching machine and the flexible coupling mechanism of compensating cylinder.
Background technology
In the prior art, slider bracket with mainly contain semifixed connection and sphere hinge draw bail connecting of compensating cylinder.Semifixed draw bail is to be connected into by piston rod circular bead surface and nut and slider bracket to have the integral body that radially relatively moves.Can not there be larger deviation at the center of the relative lathe in slide block center when its structural requirement was installed slide block, and compensating cylinder reference for installation etc. will have preferably machining accuracy, otherwise just may be when work the generation steady phenomenon such as pulsation not; When slide block bears eccentric moment, piston rod will bear a part of bending moment, cause the phenomenons such as the wearing and tearing of compensating cylinder fairlead, slider bracket bolt fracture.
The sphere hinge-coupled is to use nut check after piston rod and slider bracket union end put one group of spheric washer.Unclamp half-turn after this structural requirement nut check, make the error of bringing by unbalance loading and installation that gap and the spheric washer of this half-turn are adjusted slide block.But installation personnel is often forgotten this cover operation, causes this structure not have the effect of adjustment.In addition, whether the size in gap is suitable, is difficult to control accurately.
Below all directly affected forcing press Workpiece Machining Accuracy in the course of the work, also affected the service life of forcing press, caused maintenance cost to increase, benefit reduces.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, to provide a kind of slide block and compensating cylinder the flexible forcing press that connects, thereby improve forcing press machining accuracy and service life, reduce maintenance cost, increasing the benefit.
The purpose of this utility model is achieved in that the flexible forcing press that connects of slide block and compensating cylinder, comprise slider bracket and compensating cylinder, compensating cylinder comprises piston rod, the lower end of piston rod is towards slider bracket, the lower end of the described piston rod studs that is threaded, the outer spacer sleeve of studs is put concave spherical surface pad and protruding spherical flange, protruding spherical flange is arranged on the below of concave spherical surface pad, setting matches with the upper end of protruding spherical flange in the lower end of concave spherical surface pad, in the protruding spherical flange shoulder is set, the lower end of the studs Ball faced nut that is threaded, Ball faced nut is arranged on the shoulder, and protruding spherical flange is connected by at least two hexagon socket cap head screws with slider bracket.
One end of studs of the present utility model is connected with the piston rod end of compensating cylinder, the other end of studs puts concave spherical surface pad and protruding spherical flange, be locked on the compensating cylinder piston rod with Ball faced nut, open screwed hole at slider bracket, with screw spherical flange and support are coupled to one.
The utility model can cooperate by the sphere of concave spherical surface pad and protruding spherical flange to adjust installs and makes the accumulated error of bringing.Control the piston rod off-centre that the slide block unbalance loading causes by the gap of piston rod and flange installed surface, another conical surface of protruding spherical flange and cooperating of Ball faced nut have formed the effect that secondary is adjusted in addition, have consisted of the function that multi-direction self-adapting flexible connects.Thereby reach anti-inclined to one side effect, compensating cylinder cylinder mouth is reduced wear, and the phenomenon that prevents the slider bracket bolt fracture.
Superiority of the present utility model is mainly manifested in: 1, the requirement on machining accuracy to compensating cylinder piston rod and slide block reference for installation is not high; 2, has certain offset load resistance; 3, improved the service life of forcing press machining accuracy and forcing press.
Loosening in order to prevent the screw thread place, be connected holding screw between described studs and the Ball faced nut.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, for the flexible forcing press that connects of slide block and compensating cylinder, comprise the slider bracket 8 that is connected with slide block 9, the top of slider bracket 8 vertically arranges compensating cylinder, and compensating cylinder comprises piston rod 1, and the lower end of piston rod 1 is towards slider bracket 8.The lower end of piston rod 1 studs 2 that is threaded, studs 2 outer spacer sleeves are put concave spherical surface pad 3 and protruding spherical flange 4, protruding spherical flange 4 is arranged on the below of concave spherical surface pad 3, setting matches with the upper end of protruding spherical flange 4 in the lower end of concave spherical surface pad 3, the protruding spherical flange 4 interior shoulder 4-1 that arrange, the lower end of studs 2 Ball faced nut 5 that is threaded, Ball faced nut 5 is arranged on the shoulder 4-1, is connected holding screw 6 between studs 2 and the Ball faced nut 5.Protruding spherical flange 4 is connected by at least two hexagon socket cap head screws 7 with slider bracket 8, and each hexagon socket cap head screw 7 along the circumferential direction is distributed on the protruding spherical flange 4.
Concave spherical surface pad 3 and protruding spherical flange 4 are match grinding processing, and machining accuracy is high, and adjustable slide support 8 and compensating cylinder are installed and made the accumulated error of bringing.Control the piston rod off-centre that the slide block unbalance loading causes by the lower surface of compensating cylinder piston rod 1 and the clearance C of slider bracket 8 upper surfaces, in addition another conical surface of protruding spherical flange 4 and cooperating of Ball faced nut 5, form the effect that secondary is adjusted, consisted of the function that multi-direction self-adapting flexible connects.
