Abstract
The utility model relates to a pair arc sample plate adjusting mechanism which comprises a lower end support, an adjusting connecting rod and a supporting seat. A pair arc sample plate is fixedly hinged to the lower end support. The adjusting connecting rod comprises a thread fork head, an adjusting nut and an adjusting screw rod. One end of the thread fork head is fixedly hinged to the top end of the pair arc sample plate. The other end of the thread fork head is connected with one end of the adjusting screw rod through the adjusting nut. The other end of the adjusting screw rod is connected with the supporting seat through a pin shaft. The pair arc sample plate adjusting mechanism has the advantages of being simple in structure, convenient to operate and strong in practicability, the difference between the arcs of a crystallizer and a sector section and a theoretical arc is lowered, jiggering resistance is lowered, casting blank quality is guaranteed, and the fact that continuous casting production is carried out smoothly is guaranteed.
Description
Technical field
The utility model relates to a kind of to arc model guiding mechanism.
Background technology
Carry out arc under conticaster crystallizer, fan-shaped section are online, raise full employment so that reduce line, shorten the replacing time.The position of crystallizer and fan-shaped section is according to the shape of arc model is adjusted.The position of arc model is directly affected the accuracy of crystallizer, fan-shaped section arc.Tradition is that upper and lower side is hinged fixing to the fixed form of arc model, and is non-adjustable to the arc model, the precision of arc depended on processing and the assembly precision of equipment, and the radian of crystallizer and fan-shaped section and theoretical radian error are larger, complex structure, troublesome poeration, poor practicability.
The utility model content
The purpose of this utility model is to provide a kind of to arc model guiding mechanism, to overcome at present existing fixed the arc model is caused the poor larger problem of misfire because of equipment processing, rigging error.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of to arc model guiding mechanism, comprise lower end bearing, adjust connecting rod and supporting seat, hinged being fixed with the arc model on described lower end bearing, described adjustment connecting rod comprises screw thread jaw, adjusting nut and adjustment screw rod, one end of screw thread jaw is fixedly hinged on the top to the arc model, the other end of screw thread jaw is connected with an end of adjusting screw rod by adjusting nut, and the other end of described adjustment screw rod is connected with supporting seat by bearing pin.
Further, described screw thread jaw with the external thread rotary of adjusting screw rod to opposite.
Further, described adjusting nut two ends internal thread rotation is on the contrary
The beneficial effects of the utility model are: the utility model is simple in structure, and is easy to operate, practical, crystallizer, the arc of fan-shaped section and the error of theoretical arc have been reduced, reduce resistance of billet withdrawal, guaranteed slab quality, guaranteed carrying out smoothly of continuous casting production.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the described a kind of structural representation to arc model guiding mechanism of the utility model embodiment;
Fig. 2 is the described a kind of structure diagram to arc model guiding mechanism of the utility model embodiment.
In figure:
1, to the arc model; 2, screw thread jaw; 3, adjusting nut; 4, adjust screw rod; 5, supporting seat; 6, lower end bearing.
The specific embodiment
As shown in Figure 1, the utility model embodiment is described a kind of to arc model guiding mechanism, comprise lower end bearing 6, adjust connecting rod and supporting seat 5, hinged being fixed with arc model 1 on described lower end bearing 6, described adjustment connecting rod comprises screw thread jaw 2, adjusting nut 3 and adjusts screw rod 4, one end of screw thread jaw 2 is fixedly hinged on the top to arc model 1, the other end of screw thread jaw 2 is connected with an end of adjusting screw rod 4 by adjusting nut 3, and the other end of described adjustment screw rod 4 is connected with supporting seat 5 by bearing pin; Described screw thread jaw 2 with the external thread rotary of adjusting screw rod 4 to opposite; Described adjusting nut 3 two ends internal thread rotations are on the contrary.Rotation adjusting nut 3 can extend or shorten the distance of adjusting lever, realizes the fine setting of the length of adjustment connecting rod, and because supporting seat 5 maintains static, thereby realization is to the fine setting of the position of arc model 1.
As shown in Figure 2, totally 3 movable parts and 4 lower pairs, 3 movable parts are respectively arc model 1, screw thread jaw 2 and adjust screw rod 4,4 lower pairs comprise 3 revolute pairs and 1 moving sets, and revolute pair is the handing-over connected mode, and the adjustment connecting rod integral is moving sets, according to free degree quantity computing formula F=3*N-2PL-PH(wherein F be free degree quantity, N is the movable part number of packages, and PL is lower pair quantity, and PH is higher pair quantity) this mechanism freedom quantity F=3 * 3-2 * 4=1.Therefore, by the position of adjusting nut 3 capable of regulatings to arc model 1.
Poor generation comprises to arc model 1 self error, manual measurement error, to equipment mismachining tolerance and the rigging error of arc device to misfire for crystallizer, fan-shaped section.Wherein can reduce by improving machining accuracy arc model 1 self error, the manual measurement error can reduce by improving artificial technology's qualification.The composition error that the utility model causes for equipment mismachining tolerance and rigging error to the arc device, fixed form and structure to arc model 1 are improved, soon the upper end will be fixing arc model 1 is improved to is adjustable to arc model 1, by the position of fine setting to arc model 1, reduce the error to arc and the theoretical arc of arc model 1.Make the position of crystallizer, fan-shaped section roller more approach the arc that requires, reduce the casting blank deformation that causes because arc is inaccurate, reduce resistance of billet withdrawal.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation on its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
