Detailed Description

Referring to fig. 1-5, the present invention provides a workpiece measuring device 1 for measuring the size of a workpiece 2, in this embodiment, the workpiece 2 is to be measured by a rim, the measuring device 1 has a machine table 3, a lifting mechanism 4 disposed on the machine table 3, and a measuring mechanism 5 disposed on the lifting mechanism 4, the machine table 3 is formed with a holder 31 for the workpiece 2 to be erected, the lifting mechanism 4 can drive the measuring mechanism 5 to move from top to bottom close to the workpiece 2 for measuring the size, the lifting mechanism 4 is a conventional structure, the detailed structure of the lifting mechanism is not repeated herein, the measuring mechanism 5 has a base 51, a fixing ring 52, two upper arc blocks 53, two lower arc blocks 54, two ring frames 55, two upper arc blocks 56, two packing members 57, and two measuring units 58.

The base 51 is fixed on the lifting mechanism 4 and forms an annular hole 511; the fixing ring 52 is fixed above the base 51 corresponding to the ring hole 511 and is formed with a ring groove 521; the upper arc-shaped blocks 53 are correspondingly arranged on the fixing ring 52, a sliding rail 531 is convexly arranged below each upper arc-shaped block 53, and the sliding rail 531 is slidably arranged in the annular groove 521, so that the upper arc-shaped blocks 53 can slide along the annular groove 521 relative to the fixing ring 52; the lower arc-shaped blocks 54 are correspondingly locked and fixed below each upper arc-shaped block 53 from the lower part of the base 51; the ring frame 55 is fixedly arranged on the fixing ring 52 and surrounds the upper arc-shaped block 53; the upper arc pieces 56 are correspondingly and fixedly arranged on the ring frame 55, an arc slot 561 is formed on the inner side of each upper arc piece 56, and each arc slot 561 corresponds to the upper arc block 53 below the arc slot 561; the packing pieces 57 are respectively screwed on the upper arc-shaped blocks 53 correspondingly passing through the arc slot 561, so that the upper arc-shaped blocks 53 can be packed tightly relative to the upper arc pieces 56; the measuring units 58 are respectively and correspondingly fixed below the lower arc-shaped blocks 54, each measuring unit 58 has a transverse guide base 581, a transverse slide block 582 disposed on the transverse guide base 581, a probe 583 connected to the transverse slide block 582, and a chip blowing pipe 584 fixed on the transverse guide base 581, the transverse slide block 582 is locked on the transverse guide base 581 by two screws 585, when the screws 585 are unscrewed, the transverse slide block 582 can slide relative to the transverse guide base 581, so that the probe 583 can be adjusted in the transverse position, and the chip blowing pipe 584 can be externally connected with high-pressure gas to blow off the chips on the workpiece 2 before the probe 583 is measured.
