Detailed Description

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

An alignment device, as shown in fig. 1-2, comprises a support 1, a base 2, three fixing plates 3, three threaded rods 4, three positioning plates 5, three auxiliary frames 6, a pressure cylinder 7 and a pressure plate 8.

The base 2 is arranged on the bracket 1. Fixed plate 3 sets up on base 2, and every threaded rod 4 is rotatory respectively and is set up on fixed plate 3, and every locating plate 5 sets up the tip at threaded rod 4 perpendicularly respectively. Here, since the positioning plate 5 is rotated, in order to avoid the positioning plate 5 from touching the base 2, the base 2 is provided with three sets of grooves, and the fixing plate 3 is movable above the grooves of the base 2. Or the middle part of the base 2 is provided with a boss, and the positioning plate 5 is positioned at the outer side of the boss. When the threaded rod 4 is rotated, the positioning plates 5 are close to the middle part of the base 2, the axes of the three threaded rods 4 converge at one point, and namely the three positioning plates 5 clamp the workpiece together.

The auxiliary frame 6 is arranged above the base 2, and the auxiliary frame 6 is respectively positioned on the two fixing plate 3 supports 1 and used for placing the electric drill so as to facilitate the electric drill to process a round workpiece. The electric drill can be arranged on the auxiliary frame 6 by means of a hydraulic cylinder. In the practical production activities of the applicant, three drilling holes need to be drilled on the side surface of a circular workpiece, so that the angle between the straight lines where the axes of the two threaded rods 4 are located is 60 degrees, the auxiliary frame 6 is exactly arranged at 60 degrees, and the whole device is simple and compact.

The pressure cylinder 7 is inverted on the support 1, the pressing plate 8 is arranged at the telescopic end of the pressure cylinder 7, the pressing plate 8 is located among the three positioning plates 5, and the pressing plate 8 is used for fixing a workpiece on the base 2 and preventing the workpiece from vibrating up and down on the base 2 to influence the machining effect.

When the positioning device is used, the positions of the two positioning plates 5 are adjusted according to the principle that an inscribed circle is positioned by three straight lines, then a workpiece is placed on the base 2 between the positioning plates 5, then the positioning plates 5 are adjusted, and the circular workpiece can be gradually fixed by three positioning plates 5, namely the inscribed circle of the positioning plates 5, so that the circular workpiece is positioned. The electric drill bit on the auxiliary frame 6 is utilized to punch the workpiece, and the device can punch a plurality of drilled holes at one time without multiple alignment.

In addition, if six drill holes arranged at equal angles need to be drilled, the correction device cannot be completed, and further improvement is needed. The application aims at the technical problem and is newly designed. Referring to fig. 1, a cavity and a pin hole are formed in a threaded rod 4, a through cavity communicated with the threaded rod 4 is formed in a positioning plate 5, a sliding rod 9 is arranged in the cavity in the threaded rod 4, the sliding rod 9 is connected with the threaded rod 4 through a pressure spring 10, and the threaded rod 4 and the sliding rod 9 are freely locked through a pin shaft 11. When the pin shaft between the threaded rod 4 and the sliding rod 9 is taken down, the sliding rod 9 extends out of the positioning plate 5 under the action of the pressure spring 10. On the contrary, when the pin 11 is installed on the threaded rod 4 and the sliding rod 9, the pressure spring 10 is in a stretching state.

During the use, when accomplishing above-mentioned three drilling of punching, rotate certain angle with the work piece for slide bar 9 stretches into in above-mentioned drilling, then continues to utilize electric drill to drill, through above-mentioned design promptly, can be even beat six drilling.

It should be understood that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same, and it is obvious for those skilled in the art that the technical solutions described in the above embodiments can be modified or some technical features can be replaced equivalently as long as there is no structural conflict; and all such modifications and alterations should fall within the scope of the appended claims.
