A 096137496 Form No. A0101 Page 7 / Total 20 Page 1013253850-0 1375022 The screw 16 passes through the screw hole After the 840 is locked into the screw hole 860, the collet 86 is fixed to the baffle 84. [0012] Referring to FIG. 4 together, when assembling, the two sliding portions 242 of the adjusting portion 24 are slidably mounted in the limiting slots 222 of the corresponding supporting plate 22, and the adjusting portion 24 is passed through the sliding portion 242 thereof. The limiting slot 222 is moved up and down to be fixed at different heights of the bracket 20 . When the adjusting portion 24 is at the required height, the four fastening screws 12 respectively pass through the corresponding guiding holes 221 of the two supporting plates 22 and are locked into the corresponding threaded holes 244 of the adjusting portion 24, and the adjusting portion 24 is fixed thereto. Support plate 22 is provided. The core rod 32 of the cylinder 30 passes through the through hole 360 of the flange 36, the screw hole 246 of the adjusting portion, and is locked into the screw hole 520 of the boss 52 of the connecting member 50. The retaining ring 324 abuts The top end of the boss 52; the threaded portion 34 of the cylinder 30 is screwed into the screw hole 246 of the adjusting portion 24, and the two adjusting screws 40 are inserted into the adjusting portions 24 and the corresponding fixing holes 248, 362 of the flange 36, thereby The cylinder 3 is mounted on the adjustment portion 24. A plurality of screws (not shown) pass through the screw holes 54 of the connecting member 5 and the corresponding screw holes 620 of the main body 62 of the air gripper 60, respectively, and the air gripper 60 is fixed to the bottom of the connecting member 50. The air pressure control of the air gripper 60 and the connecting member 50 through the air cylinder 30 can be moved up and down with the core rod 32. A plurality of screws (not shown) respectively pass through the screw holes 720 of the two extensions 70 and the screw holes 662 of the two limiting plates 66 to fix the two extension bodies 70 on the corresponding limiting plate 66. The two clamping bodies 80 are fixed to the corresponding extensions 70 through the limiting holes 820 of the two holding bodies 80 and locked into one of the screw holes 740 ′ of the corresponding guiding plates 74 . The two adjusting screws 40 can be rotated up and down in the corresponding fixing holes 248, 362, and can resist the rising connecting member 50 for controlling the maximum height of the lifting claw 60 and the connecting member 50 to further adjust the workpiece to be tested. 100 drops 096137496 Form number Α 0101 Page 8 / Total 20 pages 1013253850-0 1375022 The height. Each time the drop height is adjusted, the pair of adjustment screws 4〇 must be at the same level. [0013] Referring to FIG. 5, in use, according to the drop height required for the drop test, the height of the adjusting portion 24 relative to the base 10 is adjusted, and the height between the head of the adjusting screw 40 and the adjusting portion 24 is adjusted; A control circuit (not shown) controls the charge and discharge of the cylinder 30 and the gripper 60. When the cylinder 3 is inflated, the core rod 32 of the cylinder 30 moves downward under the action of air pressure, and the core rod 32 pushes the air gripper 60 downward; when the collet 86 of the clamping body 8 is contacted When the workpiece to be tested on the base 10 is 1 ,, the air gripper 6 is inflated 'the grip portion 64 of the gripper 60 is pushed closer to each other under the push of air pressure, so that the collet 86 of the two gripping bodies 80 Clamping the workpiece to be tested 1; venting the cylinder 30 to make the cylinder vacuum> the core rod 32, the gripper 6〇, and the workpiece 100 to be tested clamped by the lost head 86 are moved up until the The connecting member 5 abuts against the head of the adjusting screw 40. At this time, the air gripper 60 is deflated, and the clamping portion 64 is bounced to drive the collet 86 to follow each other to release the workpiece to be measured. , causing the workpiece to be measured 1 0 0 to fall from a high altitude. In another embodiment of the drop test machine of the present invention, a screw hole for receiving the threaded end 322 of the core rod 32 of the cylinder 30 may be disposed on the main body 62 of the air gripper 6〇, through which the screw hole and the thread are threaded. The engagement of the end 322 secures the anger bar 32 to the body 62 of the air gripper 60 or otherwise secures the ferrule 32 directly to the body 62 of the air gripper 60. [0015] 096137496 The drop test machine of the present invention unwinds the workpieces to be tested of different sizes, and unscrews the manual screws 14 so that the sliding plates 82 of the two holding bodies 80 are respectively in the guiding grooves 742 of the corresponding extensions 70. Sliding, when the distance between the two lost heads μ meets the requirements, the manual screws 14 are respectively passed through the corresponding form number A0101 of the corresponding clamping body 8〇 page 9 / total 20 pages i n n n 1375022 bit hole 820 and rotate Into the corresponding side hole 740 of the corresponding extension body 70. In addition, the collet 86 can also be replaced according to the shape of the workpiece 100 to be tested to facilitate clamping of the workpiece 100 to be tested. The air pressure of the cylinder 30 is different from the air pressure for controlling the clamping portion 64 to be clamped and bounced. Therefore, the air pressure of the air gripper 60 can be adjusted according to the material and characteristics of the workpiece 100 to be tested, and the two limit plates 66 are controlled to clamp the workpiece to be tested. The strength of 100 avoids the damage to the workpiece 100 to be tested because the air pressure that controls the up and down movement of the air gripper 60 in the cylinder 30 is too rfj. The control circuit achieves a repeated drop test of the workpiece 100 to be tested by the frequency of charge and discharge of the cylinder 30 and the gripper 60. [0016] In summary, the present invention has indeed met the requirements of the invention patent, and the patent application is filed according to law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations in the spirit of the present invention will be apparent to those skilled in the art.
