Abstract
The utility model discloses a large-load height adjuster comprising a main frame and a lifting device; wherein two sides of the main frame are provided with sliding chutes and supporting surfaces which are symmetrical left and right and inclined; the lifting device can move along the sliding chutes and the supporting surfaces; the lifting device comprises two special-shaped nuts, two thread adjusting rods, a coupling, special-shaped nut slide blocks, and slip planes; the slide blocks move along the sliding chutes, the slip planes move along the supporting surfaces, the two special-shaped nuts have opposite spiral directions and are respectively provided with the corresponding thread adjusting rod; and as the glide planes slide on the supporting surfaces of the main frame, a distance between an upper surface and a lower surface of the main frame changes, so that the height of the height adjuster can also change. As a tensile force exerted on the special-shaped nut by the thread adjusting rod is a component force of the gravity exerted on the supporting surface of the main frame, the force exerted on the thread of the thread adjusting rod is just a fraction of the weight of an object placed on the adjuster, therefore, compared with a method adopting foundation bolts to adjust the height, the large-load height adjuster of the utility model can bear a several times larger weight.
Description
Technical field
The present invention relates to field of machining, particularly a kind of assembly of adjusting the machinery height.
Background technique
The installation of machinery, or the placement of article all will be to its setting height(from bottom)s in the time of many, and perhaps levelness is adjusted.
Existing adjusting method normally realizes through pad, correcting wedge or stone bolt.Adopt pad and correcting wedge to realize the adjustment of height or levelness, be not easy to confirm and find the pad of required specification, and need the operator to have certain experience, and need just can meet the demands through the repeated multiple times debugging.If adopt stone bolt, because screw thread is its main force part, so its bearing power is limited.
Summary of the invention
The objective of the invention is provides a kind of easy to adjust to the deficiency that exists in the above-mentioned existing technology, and bearing power is strong; Be easy to use easy disassembly, but the height adjusting block of standardized production; The single use of ability also can be used in a plurality of combinations, realizes the adjustment of object height or levelness.
In order to achieve the above object, the big load height regulator of the utility model comprises main frame, lowering or hoisting gear, and the main frame both sides have the chute and the supporting surface of symmetrical inclination, and lowering or hoisting gear can move along chute and supporting surface.
The present invention includes laterally zygomorphic two main frames.
Main frame one side of the present invention is a wallboard, and wallboard has the sliding-groove identical with chute.
Lowering or hoisting gear of the present invention comprises two nuts, two threaded adjusting bars and coupling; Nut has slide block and the slip plane that matches with the chute and the supporting surface of main frame; Slide block moves along chute, and slip plane moves along supporting surface, and the hand of spiral of two nuts is opposite; The respective threads adjustable lever is housed respectively, and two threaded adjusting bars connect through coupling.
Through the rotary threaded adjustable lever; Because two threaded adjusting bar hand of spirals are opposite; Two nuts all advance or retreat to the center synchronously, cause its rhombus slide block in the chute of main frame, to slide, and its slip surface also slides on the supporting surface of main frame; Cause the distance of the upper and lower surfaces of a main frame to change, thereby the height that is placed into the object above the height arm control is changed.
Threaded adjusting bar of the present invention has locating slot.
The present invention also comprises positioning plate, has locating slot on the positioning plate, and the main frame middle part has two positioning plate mounting grooves, and positioning plate is installed in the positioning plate mounting groove of main frame, and the locating slot of threaded adjusting bar is fixed in the locating slot of positioning plate.
Main frame of the present invention has limiting stopper, because the restriction nut moves to the main frame center.
Because the threaded adjusting bar has regulating handle, and the existence of main frame upper limit position block, the movable distance of nut is limited within the specific limits.
Because the suffered threaded adjusting draw-bar pull of nut; Be a component of the suffered gravity of supporting surface of main frame; And gravity is by on the slip surface of mean allocation to 2 nut, so the power that screw thread bore on the threaded adjusting bar just is placed into the part of the weight of the object above the regulator; Promptly compare, can bear big several times weight with the height that direct employing stone bolt is adjusted object.
Be placed into the fixing of object on the utility model, can on the base plate of main frame, make bolt hole, or on base plate, process dovetail groove, mode such as dovetail groove fixes.
The present invention has following beneficial effect than existing technology:
The weight that the present invention leans on the slip surface of nut to bear object is compared with the height that direct employing stone bolt is adjusted object, and lifting surface area has increased a lot, can bear big several times weight;
It is vertical with the direction of its suffered weight that the present invention adjusts direction highly, can regulate at any time, is convenient to use in the place of some limited space, and can be used on some special place;
The present invention can be used as some machinery that need adjust height or component of object, directly is assembled on these machineries or the object;
The present invention is when the adjustment object height, and only can there be the variation of height in controlled object, and can be as common adjustment wedge, and controlled object can move along the axial direction of adjustment screw rod;
The present invention can be used as standard parts and components production, can reduce cost greatly.
