Summary of the invention
The purpose of this utility model is to provide a kind of body of rod lifting smooth and easy, reliable and stable elevating lever rolling guiding regulating device flexibly.
For reaching goal of the invention the technical solution adopted in the utility model, be:
Elevating lever rolling guiding regulating device, it is installed on respectively top and bottom between the adjacent body of rod of elevating lever, it is characterized in that: comprise the guide type shoe being connected on the body of rod with lozenges, the wedge block that can slide along its lozenges is installed on described guide type shoe, on described wedge block, be connected with and can, with the bolt that drags of its motion, between described wedge block and the body of rod corresponding thereto, be provided with needle roller sub-assembly.
Further, the described guide type shoe of bottom is arranged on the outer surface of inside body of rod bottom of the adjacent body of rod, and the described guide type shoe at top is arranged on the inner surface at outside body of rod top of the adjacent body of rod.
Further, the elevating lever rolling guiding regulating device of bottom described in drag bolt and be provided with to be fixed and use clamp nut.
Further, the described wedge block of the elevating lever rolling guiding regulating device at top is fixed by housing screw.
It is the gap adjustment of needle roller sub-assembly that the utility model is adjusted motion converter by the wedge block inclined-plane of elevating lever rolling guiding regulating device.Smooth and easy for guaranteeing the lifting of elevating lever, at every joint, there are the top of the relative motion body of rod and bottom all to assemble elevating lever rolling guiding regulating device, body of rod top and bottom, inner surface and outer surface all have elevating lever rolling guiding regulating device, like this, no matter the body of rod is in arbitrary height, all guarantee every pole body and the guiding of all effectively rolling with its adjacent inside and outside body of rod, and each elevating lever rolling guide apparatus can be stepless adjusting rod body space, both guarantee the flexible smoothness of every pole body lifting, guaranteed again the reliability of whole motion process.
The course of work of the present utility model is as follows: rotation drags bolt and drives wedge block to slide along the lozenges of guide type shoe, needle roller sub-assembly is along with the lozenges slip level of wedge block along guide type shoe moves left and right, the process of this adjustment is stepless continuous, between the body of rod gap adjust suitable after, tighten immediately clamp nut or housing screw, make the gap between the body of rod keep stablizing constant.The adjustment direction of the elevating lever rolling guiding regulating device of bottom and the elevating lever rolling guiding regulating device at top is contrary.When the elevating lever rolling guiding regulating device of bottom is adjusted, wedge block is up, and needle roller sub-assembly level is servo-actuated moves right, and the body of rod gap of the inner body of rod and the outside body of rod reduces; Wedge block is descending, and needle roller sub-assembly follow-up horizontal is moved to the left, and the body of rod gap of the inner body of rod and the outside body of rod increases.During the adjustment of the elevating lever rolling guiding regulating device at top, wedge block is up, and needle roller sub-assembly level is servo-actuated moves right, and the body of rod gap of the outside body of rod and the inner body of rod increases; Wedge block is descending, and needle roller sub-assembly follow-up horizontal is moved to the left, and the body of rod gap of the outside body of rod and the inner body of rod reduces.
The beneficial effects of the utility model: guarantee every pole body and the guiding of all effectively rolling with its adjacent inside and outside body of rod, and be step-less adjustment body of rod gap, both guaranteed the flexible smoothness of every pole body lifting, guarantee again the reliability of whole motion process.
