Abstract
The utility model discloses an unit direction holds up paper -back edition to put, including the thrust plate, be equipped with thrust plate sleeve and thrust plate fixed lug on the thrust plate, be connected with the pneumatic cylinder on the thrust plate fixed lug, the pneumatic cylinder sets up on the fixed plate, still install fixed guide cylinder on the fixed plate, it holds up flat pole and hollow direction to hold up flat pole can follow fixed guide cylinder to slide to be equipped with hollow direction in the fixed guide cylinder, the one end socket joint that flat pole was held up to hollow direction is in the thrust plate sleeve, hollow direction is held up and is equipped with stay bolt in the flat pole, the one end that stay bolt is close to the thrust plate is equipped with the stay bolt arm -tie, stay bolt's the other end is equipped with fastening nut. The utility model discloses eliminated on actuating mechanism because of the inhomogeneous alternating stress who leads to of thrust plate external force concentrates the problem, avoidd the phenomenon that stress concentration leads to metal fatigue failure, prolonged the life of equipment greatly, reduced equipment trouble and rateed, reduced equipment spare parts and drop into the expense.
Description
Technical field
The utility model belongs to mechanical equipment technical field, is specifically related to a kind of unit guiding and holds up leveling device.
Background technology
Domestic existing interlocking set, in transhipment, packing, most in regular material what adopt is that thrust plate and 2 to 4 is overlapped fixed guide cylinder, leads and hold up flat bar to be led by powered actuation mechanism hydraulic actuating cylinder component material to hold up flattening mechanism.When now guiding holds up flat bar to be connected with thrust plate, most employing is that large-diameter thread connects.Prevent the method for thread looseness majority from adopting following two kinds of structures: 1, to be hold up flat rod end head to make negative thread in guiding, open counterbore bolt screw-in guiding at thrust plate and hold up flat rod end head negative thread to strain the pilot bar (as shown in Figure 1) screwed, prevent from loosening.2, be that large-diameter thread screws out thrust plate, adopt circular nut locking (as shown in Figure 2), prevent from loosening.And above-mentioned two kinds of structures have following common defect: one be frequent transhipment, packing, regular load comparatively heavy material time, because material load is heavier and irregular, then thrust plate will bear the power of lateral heterogeneity, cause thrust plate to produce displacement to side direction.And guiding holds up flat bar cannot shifted laterally by the constraint of fixed guide cylinder, flat bar junction must be held up to produce at thrust plate and guiding and shear reverse stress frequently, simultaneously original guiding hold up flat bar and thrust plate sleeve connection place shorter, the lateral shearing force of large load, axial tensile force acts on shorter adapter shaft, can easily exceed the plastic deformation curve of bar axle metal material, bar axle not only can be caused to extend, guiding holds up flat rod end head negative thread tie bolt or stripped nut to cause Dogbolt or nut loosening because bearing reverse stress for a long time, but also can metal fatigue failure be accelerated, follow-up cause guiding hold up flat bar and thrust plate screw thread fit not tight.After frequent operation, guiding holds up flat bar and thrust plate internal and external threads often to impact to cause losing efficacy, initiation equipment breakdown.Two what be that guiding holds up flat bar to be connected with thrust plate to adopt is that large-diameter thread connects, the relief groove of 2-3mm is had in order to thread cutting being threaded with two parts transition region that leads, and this part is body diameter there is significantly step-graded region, belongs to focal point of stress.Long-term transhipment, packing, regular load are comparatively after heavy material, and this focal point of stress, after the accumulation of reverse stress change frequency, radial metal fatigue failure will occur, and produces fracture.
Utility model content
The purpose of this utility model is to solve the technical matters existed in prior art, there is provided one can prevent guiding from holding up flat bar to be connected binding thread with thrust plate to loosen and cause connecting thread to lose efficacy, unit stress can also being avoided to concentrate cause metal fatigue to rupture leads and holds up leveling device.
In order to achieve the above object, the utility model is by the following technical solutions: a kind of unit guiding holds up leveling device, comprise thrust plate, described thrust plate is provided with thrust plate sleeve and thrust plate fixed lug, described thrust plate fixed lug is connected with hydraulic actuating cylinder, described hydraulic actuating cylinder is arranged on adapter plate, described adapter plate is also provided with fixed guide cylinder, be provided with hollow guiding in described fixed guide cylinder and hold up flat bar and hollow guiding holds up flat bar can slide along fixed guide cylinder, described hollow guiding holds up one end socket joint of flat bar in thrust plate sleeve, described hollow guiding is held up in flat bar and is provided with stay-bolt, described stay-bolt is provided with stay-bolt arm-tie near one end of thrust plate, the other end of described stay-bolt is provided with clamp nut.
Further, described stay-bolt arm-tie and thrust plate sleeve are respectively equipped with knock hole, in described knock hole, are provided with dowel bolt.
Further, described thrust plate sleeve, fixed guide cylinder and hollow guiding hold up flat bar to be respectively two.
The utility model hinge structure has following beneficial effect: the guiding that the utility model adopts hollow guiding to hold up flat bar to replace original solid large-diameter thread to connect holds up flat bar, and hold up in flat bar at hollow guiding an outside thread stay-bolt is set, the overall through hollow guiding of this stay-bolt holds up flat bar and stay-bolt is provided with stay-bolt arm-tie near one end of thrust plate, the other end is provided with clamp nut, hold up flat bar to be connected original thrust plate and guiding to coordinate screwed to be connected by screw thread simultaneously and change hollow guiding into and hold up flat bar by flush fit socket joint in thrust plate sleeve, the focal point of stress not having body diameter that significantly Spline smoothing and relief groove occur like this to cause in this region, actuating unit eliminates the reverse stress concentration problem caused because thrust plate external force is uneven, evade stress and concentrate the phenomenon causing metal fatigue failure.Extend the length of stay-bolt simultaneously, increase the flexibility of stay-bolt, then the limit stress of stay-bolt reduces, therefore the ultimate load of stay-bolt also reduces, substantially prolongs the service life of equipment, reduce equipment failure rate, decrease Spare Parts Meteorological.
