Description
Technical field
The present invention relates to the accurate lift adjustment bracing or strutting arrangement of a kind of screw.
Background technology
Existing jacking system roughly can be divided into scissor-type, pinion and-rack and hydropneumatic formula according to the structure that adopts.Wherein, the scissor-type jacking system is had relatively high expectations to the synchronism of crotch, and its structure steadily can only not used at stationary application; The pinion and-rack jacking system is had relatively high expectations to tooth bar, and general bearing force is less, and needs supplementary structure; Hydropneumatic formula jacking system uses on the large-tonnage support platform.Therefore, the jacking system of above structure all is not suitable in the support of big carrying, high-precision requirement and uses.At present, it is comparatively common that screw moves control apparatus, but owing to structural limitations is not also used it on the lifting supporting and adjusting device.
Summary of the invention
At have the deficiency that mobile jacking system exists now in the support applications of big carrying, high-precision requirement, the object of the present invention is to provide the accurate lift adjustment bracing or strutting arrangement of a kind of screw, described device can be realized the accurate lift adjustment of bay-lift vertical direction position by regulating the adjustment dish, be mainly used in laboratory equipment and need and also can play the effect of conventional type jacking system in the instrument and meter of the horizontal lift adjustment of accurate adjustment.
The present invention is achieved by the following technical solutions.
The accurate lift adjustment bracing or strutting arrangement of a kind of screw, described device mainly is made up of main basal base, retainer, lifting table, adjustment dish, lock screw and maintenance bearing.
The seat end of the main basal base of described device and seat are as hollow cylindrical, at the bottom of the seat body is positioned at top and cross-sectional area less than seat at the bottom of cross-sectional area described device is stable to be placed to keep, seat side on one's body has two boss, the boss top is provided with the cross bar of a level, and the described seat end, seat body, boss and cross bar are integrated; At the bottom of the frame of retainer and frame as the hollow cylindrical integral structure, the frame body be positioned at the bottom of the frame top and cross-sectional area less than frame at the bottom of cross-sectional area; The coarse adjustment graduated scale is carved with in the abutment body side of lifting table, reference during for coarse adjustment, and the abutment body below is provided with screw rod; The Pan Ding of adjustment dish and dish are as the hollow cylindrical integral structure, Pan Ding be positioned at dish on one's body side and cross-sectional area greater than dish body cross-sectional area, be carved with the trimming scale scale on the dish top side face, reference during for fine setting, circumferencial direction has the auxiliary hole of adjusting, can be by the instrument adjustment when guaranteeing to support heavier load, there is negative thread dish body inboard.
Retainer is positioned at main basal base coaxial line direction top, cooperate at the bottom of the frame of the cross bar embedding retainer of main basal base and place, make retainer and main basal base form the seam location and be fastened together, guarantee structure integraty and the concentricity of retainer and main basal base, thereby reduce the heeling error when adjusting; Frame body one side of retainer is provided with lock screw.The abutment body of lifting table places the retainer hollow space, closely cooperates with retainer, keeps it to adjust direction by retainer; Screw rod passes retainer and adjustment dish from top to bottom successively, inserts in the main basal base.Captive joint with two boss of main basal base respectively in the Pan Ding two ends of adjustment dish, the dish body inserts in the seat body of main basal base, dish body both sides cooperate in the seat body that embeds main basal base by a maintenance bearings respectively, main basal base rotation relatively, can finely tune by the auxiliary hole rotation adjustment dish of adjusting, can also bear larger axis to load simultaneously; The screw rod of lifting table stretches into the dish body and is threaded with the dish body.
The hollow space cross-sectional area of preferred main basal base and retainer is identical; The abutment body of preferred lifting table is the first quarter moon formula; The abutment body top of preferred lifting table is provided with tapped bore, is used for fixing its structure that supports or load object.
The working process of described device is as follows: adjustment dish screw rod relative and lifting table rotates, screw rod can produce the motion perpendicular to hand of rotation, thereby the drive lifting table rises overally or descends, realize coarse adjustment, the coarse adjustment scale graduation that is engraved on lifting table abutment body side by observation can accurately be controlled the height that described device rises or descends; Adjustment dish circumferencial direction has the auxiliary hole of adjusting, and by the auxiliary hole of adjusting of instrument adjustment, can further accurately control the height that described device rises or descends by observing the trimming scale chi of carving adjustment dish dish top side face; After adjusting to desired location, by the lock screw of lifting table abutment body side lifting table is locked, realize the positioning supports effect of described device.
Beneficial effect
1. the accurate lift adjustment bracing or strutting arrangement of a kind of screw of the present invention can be realized the accurate lift adjustment of support platform, can support big load;
2. the accurate lift adjustment bracing or strutting arrangement of a kind of screw of the present invention, owing to produce the non-directional deflection in the time of may existing the gap to make the lifting table motion between adjustment dish screw thread relative and lifting table is in transmission connection, therefore be provided with retainer, described retainer and main basal base form the seam location and are fastened together, can guarantee structure integraty and the concentricity of retainer and main basal base, reduce the heeling error when adjusting, thereby guarantee the positional precision that lifting table rises or descends, the assurance lifting table is reliably located;
3. the accurate lift adjustment bracing or strutting arrangement of a kind of screw of the present invention, the adjustment dish supports with pair of bearings and embeds in the main basal base, be carved with the trimming scale scale on the adjustment dish, by the rotation adjustment of the auxiliary adjustment hole on its circumferencial direction dish, when adjusting disc spins, because it all is fixed on up and down in the main basal base, can not producing up and down during rotation, string moves, simultaneously can also bear larger axis to load, guarantee that described device can carry out lift adjustment by instrument when supporting big load;
4. the accurate lift adjustment bracing or strutting arrangement of a kind of screw of the present invention, the abutment body top of lifting table is provided with tapped bore, is convenient to fix its structure that supports or load object.
