Example 1

As shown in the figure, the positioning tool for the round hole casting provided by the utility model comprises a mounting base 1, wherein the mounting base 1 plays a supporting role. A first guide plate 21 is arranged on one side of the mounting base 1, a second guide plate 22 is arranged on the adjacent side of the mounting base, and the first guide plate 21 and the second guide plate 22 limit the freedom degree of the circular hole casting in the horizontal direction.

The opposite sides of the second guide plate 22 are provided with a first supporting block 31 and a second supporting block 32, and a three-jaw pneumatic device 4 and a two-jaw pneumatic device 5 are arranged between the second guide plate 22 and the first supporting block 31 and between the second guide plate 32 and the second supporting block 32, and the three-jaw pneumatic device 4 and the two-jaw pneumatic device 5 are used for positioning round hole castings.

The three-jaw pneumatic device 4 comprises a three-jaw chuck 41 and a first jaw 42, wherein the first jaw 42 comprises a clamping block and a sliding block, the clamping block and the sliding block are connected through bolts, and the first jaw 42 is of a three-jaw structure. The three-jaw chuck 41 is internally provided with a spiral guide rail and the side surface is provided with a linear guide rail; the lower part of the sliding block is provided with a spiral clamping groove matched with the spiral guide rail, and the side surface of the sliding block is provided with a linear clamping groove matched with the linear guide rail. When the spiral guide rail in the three-jaw chuck 41 rotates, the first jaw 42 can be driven to move along the linear guide rail, so that the round hole casting is positioned.

A rotary roller 43 is arranged in the first claw 42, and the rotary roller 43 is connected with the first claw 42 through a pin 44. When the first claw 42 moves outwards to position the round hole casting, the rotary roller 43 contacts with the round hole casting, and the rotary roller 43 can rotate, so that scratches of the first claw 42 on the surface of the round hole casting can be prevented when the round hole casting is positioned, and the appearance of the casting is prevented from being damaged.
