Abstract

An alignment apparatus of a disc-shaped forging circle center comprises calipers, a drop hammer, a suspension wire and an adjusting pulling ring. Tail ends of two caliper arms of the calipers are mutually and movably riveted and lengths of the two caliper arms of the calipers are the same. A movable riveting position of the calipers is provided with a suspension wire hole. The suspension wire hole passes through the movable riveting position of the calipers so that the suspension wire passes through the suspension wire hole and then a suspension position of the suspension wire is restrained at the movable riveting position of the calipers. One end of the suspension wire is fixedly connected to the drop hammer and the other end of the suspension wire is winded and connected to the adjusting pulling ring so that a height of the drop hammer is adjusted through pulling through the adjusting pulling ring. In the invention, a geometric property that a middle line of a bottom edge of an isosceles triangle formed by the calipers and a height on the bottom edge are superposed is used so that the apparatus with the simple structure is provided so as to accurately align the disc-shaped forging circle center.

Description

The alignment device in the disk shape Forging center of circle

Technical field

The present invention relates to the positioner technical field of workpiece, more particularly to a kind of centering dress in disk shape Forging center of circle Put.

Background technology

In current flat-die forging industry, in the center of circle punching of disk shape Forging, generally carried out using range estimation and experience The centering in the center of circle, and the eyesight and concentration of people can be adversely affected under the working environment of high temperature, it is particularly outer in processing When justifying very big forging, the centering in the forging center of circle is more difficult, thus the eccentric situation of punching forgings happens occasionally, and causes the later stage The product for processing is unqualified.

The content of the invention

In view of this, it is necessary to which a kind of alignment device for being capable of the accurate disk shape Forging center of circle in the centering center of circle is provided.

A kind of alignment device in the disk shape Forging center of circle, including clamp, sash weight, messenger wire and regulation draw ring, the clamp The equal length of two clamp arms, one end mutually activity riveting of two clamp arms of the clamp, in the clamp Messenger wire hole is offered at movable riveting, at the activity riveting of clamp described in the insertion of the messenger wire hole, described in two of the clamp The other end of clamp arm is respectively provided with identical measurement arm, and one end of the measurement arm is fixedly connected with the clamp arm, the survey The other end of amount arm is used to clamp disk shape Forging, angle in obtuse angle between the measurement arm and the clamp arm, with by folder The tight clamp arm causes the other end of the measurement arm to be fully contacted with disk shape Forging, and the messenger wire passes through the messenger wire Hole so that the messenger wire is suspended at the activity riveting of the clamp, one end of the messenger wire is fixedly connected with the sash weight, institute The other end of messenger wire is stated around being connected on the regulation draw ring, with by lifting the height for adjusting the draw ring adjustment sash weight.

Present invention utilizes clamp constitute isosceles triangle base on center line and base on height coincide it is several What property, opens up messenger wire hole in the movable riveting point of two clamp arms, and penetrates in the messenger wire hole and be connected with hanging for sash weight Line, there is provided the device of simple structure is with the center of circle of accurate centering disk shape Forging.

Description of the drawings

Fig. 1 is the structural representation of the alignment device in the disk shape Forging center of circle.

Fig. 2 is the structural representation that anti-skidding paster is connected with the clamp arm of the clamp in Fig. 1.

In figure：Clamp 10, clamp arm 101, measurement arm 102, messenger wire hole 11, anti-skidding paster 12, sash weight 20, messenger wire 30, tune Section draw ring 40.

Specific embodiment

In order to be illustrated more clearly that the technical scheme of the embodiment of the present invention, below by to be used attached needed for embodiment Figure is briefly described, it should be apparent that, drawings in the following description are some embodiments of the present invention, common for this area For technical staff, on the premise of not paying creative work, can be with according to these other accompanying drawings of accompanying drawings acquisition.

Fig. 1 is refer to, a kind of alignment device in the disk shape Forging center of circle includes clamp 10, sash weight 20, messenger wire 30 and adjusts Draw ring 40, the equal length of two clamp arms 101 of clamp 10, the mutual activity riveting in one end of two clamp arms 101 of clamp 10 Connect, messenger wire hole 11 is offered at the activity riveting of clamp 10, at the activity riveting of 11 insertion clamp 10 of messenger wire hole, clamp 10 The other end of two clamp arms 101 is respectively provided with identical measurement arm 102, and company is fixed in the one end and clamp arm 101 for measuring arm 102 Connect, the other end for measuring arm 102 is used to clamp disk shape Forging, angle in obtuse angle between measurement arm 102 and clamp arm 101, with The other end of measurement arm 102 is caused to be fully contacted with disk shape Forging by grip wrench arm 101, messenger wire 30 passes through messenger wire hole 11 so that messenger wire 30 is suspended at the activity riveting of clamp 10, one end of messenger wire 30 is fixedly connected with sash weight 20, messenger wire 30 it is another One end adjusts height that draw ring 40 adjust sash weight 20 to pass through lifting around being connected on regulation draw ring 40.

Two waists of the clamp arm 101 of two equal lengths of clamp 10 equivalent to isosceles triangle, two measurement arms 102 One end between line equivalent to isosceles triangle base, when two measure arms 102 one end line be in a level During face, the messenger wire 30 is straightened by the effect of 20 gravity of the sash weight and perpendicular to the horizontal plane, then messenger wire 30 is vertical In the base of isosceles triangle, the straight line that now messenger wire 30 is located is the height on isosceles triangle base, then messenger wire 30 is located Straight line be also center line on isosceles triangle base, if now the end of two measurement arms 102 of clamp 10 is stuck in level and puts The diametrical position of the disk shape Forging put, then messenger wire 30 is located straight line and the intersection point of disk shape Forging, i.e. sash weight 20 fall to justifying Position on disk forge piece is the center of circle of disk shape Forging.

Further, Fig. 2 is refer to, anti-skidding paster 12 is provided with the end of measurement arm 102, to prevent because measuring 102 phase of arm Disk shape Forging is slided and causes error.

The course of work of the alignment device in the disk shape Forging center of circle is below described：The disk die forging in the centering center of circle will be treated The end of the measurement arm 102 of clamp 10 is stuck in the diametrical position of disk shape Forging by part horizontal positioned, and lifting or decentralization are adjusted and drawn Ring 40, makes sash weight 20 stretch messenger wire 30, while the lower end of sash weight 20 is contacted with the surface of disk shape Forging, and in the circle The position that the surface of disk forge piece is contacted with sash weight 20 puts signs on, with the center of circle of centering disk shape Forging, due to flat-die forging The forging for going out is cylindrical and irregular, therefore needs the measurement position of clamp 10 is varied multiple times, to the disk shape Forging of each centering The center of circle is neutralized process, with the center of circle of centering disk shape Forging as precisely as possible.
