Description

Technical Field

[0001] The utility model relates to the technical field of metal casting processing, in particular to a positioning device for metal casting processing. Background Art

[0002] Metal castings are made by melting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling, solidification and cleaning, metal products with predetermined shapes, sizes and performances are obtained. However, metal castings generally cannot directly meet the corresponding finished product standards after the casting is completed. Instead, they still need to be processed by grinding, polishing or drilling before they can be put into use. Therefore, positioning devices are required for processing and use.

[0003] In the prior art, the positioning structure of metal castings generally uses different fixing parts for different shapes. For example, due to the shape characteristics of plate-shaped metal parts and tubular metal parts during processing, the same fixing parts cannot be effectively fixed, so the processing equipment cannot process the plate-shaped metal parts after processing the tubular metal parts. The fixing parts on some processing equipment are replaced. This processing equipment can process the metal parts of different shapes after the fixing parts are replaced. However, such operation is also time-consuming. Therefore, it is necessary to design a metal part positioning structure for fixing metal parts of different shapes on the processing equipment.

[0025] The positioning structure designed for metal parts in this application is two groups, and the two groups are horizontally located on the processing equipment of the metal parts, so that both sides of the metal parts can be fixed. The fixation described in the following text is only a single-sided fixation of the metal parts.

[0026] In the present application, the positioning frame 1 3 and the positioning frame 2 4 can be corresponded up and down by the movement of the telescopic frame 2 on the placement frame 1, so that the positioning frame 1 3 and the positioning frame 2 4 can be tightly fitted together. At this time, one side of the metal part will be located between the positioning frame 1 3 and the positioning frame 2 4, and then the side wall of the metal part is fixed by the cooperation of the telescopic fixing member 1 5 and the telescopic fixing member 2 6. The telescopic fixing member 1 5 and the telescopic fixing member 2 6 designed in the present application both act on the positioning frame 1 3 and the positioning frame 2 4. The mutual cooperation between the four components can fix one side of the plate-shaped metal part and the tubular metal part. The advantage of the present application is that the method of switching to fix metal parts of different shapes is relatively convenient and quick, will not delay the operator for a long time, and improves the processing efficiency.

[0027] Preferably, both the positioning frame 1 3 and the positioning frame 2 4 are provided with an assembly groove 341, and the two assembly grooves 341 correspond vertically. The assembly groove 341 is located in the middle position of the positioning frame 1 3 or the positioning frame 2 4, and each of the assembly grooves 341 has limiting grooves 342 on both sides thereof. The positioning frame 1 3 is also provided with an arc groove 31 in the middle position, and the arc groove 31 corresponds vertically to the assembly groove 341 provided on the positioning frame 2 4.

[0028] In the present application, the assembly groove 341 and the limit groove 342 opened on the positioning frame 1 3 and the positioning frame 2 4 are used to place the telescopic fixing member 1 5 and the telescopic fixing member 2 6.

[0029] Preferably, both sides of the positioning frame 1 3 and the positioning frame 2 4 are symmetrically provided with movable connecting plates 343, and each two vertically corresponding movable connecting plates 343 are provided with a limiting connecting rod 344. The cooperation between the movable connecting plates 343 and the limiting connecting rod 344 can limit the positioning frame 1 3 and the positioning frame 2 4, and prevent the positioning frame 2 4 from deviating from the vertical position of the positioning frame 1 3 when sliding up and down following the telescopic frame 2.

[0032] In the present application, the operator can turn the knob 51 to make the threaded rod 52 rotate in the placement frame 1, and when the threaded rod 52 rotates, the rectangular movable plate 53 can slide in the assembly groove 341. Since the positioning frame 3 is provided with an arc groove 31, the middle position of the positioning frame 3 has a certain arc shape, so that the placement of the plate-like metal parts is not stable, so the rectangular movable plate 53 can fill the arc groove 31 provided on the positioning frame 3 when sliding upward in the assembly groove 341, so that the positioning frame 24 can fix the plate-like metal parts between the positioning frame 24 and the positioning frame 3 when moving downward.

[0033] Preferably, the telescopic fixing member 6 includes a knob 61, a threaded rod 62, a sliding plate 63 and an arc frame 65.

[0034] In the present application, the operating principle of the telescopic fixing member 2 6 is consistent with that of the telescopic fixing member 1 5, but in the telescopic fixing member 2 6, when the sliding plate 63 slides in the assembly groove 341, the arc frame 65 will extend out of the assembly groove 341. At this time, the tubular metal part can be placed in the arc groove 31 on the positioning frame 1 3, and then the positioning frame 2 4 moves downward until the arc frame 65 contacts the upper end of the metal tube, and the tubular metal part is fixed by the arc frame 65 and the positioning frame 1 3.
