Abstract
The utility model discloses an automatic centering scriber, which consists of a scriber holder and a scriber. The scriber holder is elongated, an elongated through groove is arranged on the longitudinal center axis of the scriber holder, two cylindrical pins which are symmetrical to each other are arranged on two sides of the panel surface of the lower portion of the scriber holder, small cylindrical pins are respectively arranged between each cylindrical pin and the elongated through groove, heights of the small cylindrical pins are identical and lower than those of the two cylindrical pins, and the scriber penetrates through the elongated through groove of the scriber holder vertically, and is fixed on the scriber holder by the aid of a nut arranged above the scriber and a gasket arranged below the scriber. According to the principle that the perpendicular bisector of any arc on a circle passes through the center of the circle, the scriber can realize automatic centering by means of arranging the cylindrical pins on the scriber holder, so that scribing operation can be more convenient and faster, working efficiency is increased greatly, and scribing accuracy is improved. Further, service range of the scriber can be expanded by the aid of an auxiliary scriber holder.
Description
Technical field
The utility model belongs to small tool, specifically, relates to a kind of chalker that can determine the center of circle automatically.
Background technology
In real work, when definite ship box body end-face hole,, must utilize the overlapping height that reaches screw to be determined branch circle center of polylith black iron earlier because the part large-size box is higher, determine the reference circle center with scriber, mark reference circle.Such operating procedure is many, and spended time is long, and is particularly bigger to producing the mach effectiveness affects of ship in enormous quantities.Equally, when determining the end-face hole of disk-like accessory, as seal disc, output flange etc., desired screw distribution circle size is bigger usually, can not reach requirement with common scriber, must operate with lengthening scriber two people.Earlier black iron is placed on the center of part in the dish, find out the center that institute's pore size distribution of drawing is justified according to existing endoporus of part or cylindrical in the dish, determine that again institute's pore size distribution of drawing justifies, one people is with scriber one end centring, another people is the center with other end scriber, adjusting distribution circle that scriber is asked is that distribution circle is irised wipe out in radius rotation one, determines to draw the center in hole again.So, many people's operations are wasted time and energy, and the more important thing is, are shifted easily if control bad scriber, cause home position to be forbidden and the generation quality problems, even institute's processing parts is scrapped.
The utility model content
The purpose of this utility model is to provide a kind of can determine the center of circle, chalker convenient to operation automatically.
The technical solution of the utility model is as follows: a kind of self-centering scriber, comprise scriber frame and carbide alloy bolt scriber, described scriber frame is a strip, on the longitudinal centre line of described scriber frame, have the strip groove, bilateral symmetry is provided with two straight pins on the base plate of described scriber frame bottom, be provided with the roundlet pin between this straight pin and the described bar shaped groove, and the height of all roundlet pins is equal, and is lower than two straight pins on the described scriber frame; Described carbide alloy bolt scriber vertically passes the strip groove of described scriber frame, and by the nut of top and the packing ring of below described scriber is fixed on the described scriber frame.
During line, the position of drawing the size adjusting scriber according to examination, and fix with nut; Go deep into two straight pins on the scriber frame in the workpiece hole and be close on the inwall of workpiece hole, roundlet pin on the scriber frame leans against on the end face of workpiece, then two straight pins on the scriber frame keep the state of being close to the inwall of workpiece hole, rotate a circle in workpiece hole, mark distribution circle.
Described secondary scriber frame also is a strip, and has the strip groove on its longitudinal centre line, vertically is installed with the secondary scriber of carbide alloy bolt on the strip groove of described secondary scriber frame, and is fixed on the secondary scriber frame of described carbide alloy bolt by nut.The setting of secondary scriber frame has enlarged the size range that scriber is rule, and makes the range of application of scriber increase.
Described straight pin and roundlet pin are elastic cylindrical pin.Help the replacing and the installation of straight pin and roundlet pin.
Beneficial effect: upward the perpendicular bisector of any arc length must be by the principle in the center of circle by circle in the utility model utilization, on the scriber frame, be located at the method for straight pin, realized the self-centering of scriber, make line work become convenient and swift, not only improve operating efficiency greatly, and improved the degree of accuracy of line.In addition, secondary scriber frame is provided with the scope of application that has enlarged scriber.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Embodiment one
A kind of self-centering scriber, as Fig. 1, Fig. 2, shown in Figure 3, form by scriber frame 1 and bolt scriber 8, scriber frame 1 is the strip steel part, on the longitudinal centre line of scriber frame 1, offer the strip groove, two holes of bilateral symmetry processing on the base plate of scriber frame 1 bottom, an elastic cylindrical pin 3 is equipped with in each interference in these two holes, have four apertures on the base plate between this straight pin 3 and the described bar shaped groove, an elastic cylindrical pin 4 is equipped with in each interference in these four apertures, and the height of all roundlet pins 4 is equal, and is lower than two straight pins 3 on the described scriber frame 1; Described bolt scriber 8 vertically passes the strip groove of described scriber frame 1, and by the nut 6 of top and the packing ring 9 of below bolt scriber 8 is fixed on the scriber frame 1.
During line, according to the position of examination stroke size adjusting bolt scriber 8, and fixing with nut 6; Go deep into two straight pins 3 on the scriber frame 1 in the workpiece hole and be close on the inwall of workpiece hole, roundlet pin 4 on the scriber frame 1 leans against on the end face of workpiece, then two straight pins on the scriber frame keep the state of being close to the inwall of workpiece hole, in workpiece hole, rotate a circle, mark distribution circle.
Embodiment two
A kind of self-centering scriber, as shown in Figure 4, the secondary scriber frame 2 of packing ring on the scriber among the embodiment one 9 usefulness is replaced, secondary scriber frame 2 also is the strip steel part, and on its longitudinal centre line, have a strip groove, on the strip groove of described secondary scriber frame 2, vertically be installed with the secondary scriber 7 of bolt, and be fixed on the secondary scriber frame 2 by nut 5.
During line, the direction of bolt scriber 8 is turned, draw size according to examination and determine the position of the secondary scriber 7 of carbide alloy bolt by the position of adjusting nut 6 and nut 5 and fix; Go deep into two straight pins 3 on the scriber frame 1 in the workpiece hole and be close on the inwall of workpiece hole, roundlet pin 4 on the scriber frame 1 leans against on the end face of workpiece, then two straight pins on the scriber frame keep the state of being close to the inwall of workpiece hole, in workpiece hole, rotate a circle, mark distribution circle.
