[0022] like Figure 1 to Figure 2 As shown, an internal thread detection machine based on coordinate measurement includes a base 1, a detection machine body 2 is fixedly installed on the top right side of the base 1, a probe 3 with a telescopic function and movable up and down is arranged on the left side of the detection machine body 2, a slide plate 4 that can slide left and right is arranged on the top left side of the base 1, a vertical plate 5 is fixedly installed on the top of the slide plate 4, three clamping rods 6 are arranged on the side of the vertical plate 5 close to the detection machine body 2, and a driving mechanism 7 for driving the three clamping rods 6 to move closer to or away from each other is arranged on the vertical plate 5. It should be noted that first, the staff can judge from the size of the annular part, choose to fix it from the inside of the annular part by internal support, or choose to fix it from the outside of the annular part by clamping. If the internal support is selected, the annular part can be sleeved on the outside of the three clamping rods 6, and then the driving mechanism 7 is controlled to make the three clamping rods 6 move away from each other. Finally, the driving mechanism 7 is controlled to drive the annular part to rotate according to a preset angle and speed. If the clamping is selected, the annular part can be placed in the middle of the three clamping rods 6, and then the driving mechanism 7 is controlled to make the three clamping rods 6 move closer to each other. Finally, the driving mechanism 7 is controlled to drive the annular part to rotate according to a preset angle and speed.
[0023] like Figure 1 , Figure 2As shown, the driving mechanism 7 includes a mounting plate 71, a mounting plate 71 is fixedly mounted on the side of the vertical plate 5 away from the detection machine body 2, a rotatable circular plate 73 is movably mounted on the side of the vertical plate 5 close to the detection machine body 2, a servo motor 72 for driving the circular plate 73 to rotate is fixedly mounted on the top of the mounting plate 71, a rotatable inner gear ring 74 is movably mounted on the side of the circular plate 73 close to the detection machine body 2, a circular ring 75 is fixedly mounted on the side of the inner gear ring 74 close to the detection machine body 2, three evenly distributed gears 76 are movably mounted on the side of the circular plate 73 close to the detection machine body 2, each gear 76 is meshed with the inner gear ring 74, three evenly distributed slide grooves 77 are opened on the side of the circular ring 75 close to the detection machine body 2, a slide rod 78 is movably mounted inside each slide groove 77, each slide rod 78 is fixedly mounted with a rack 79 on the side close to the detection machine body 2, and each rack 79 is meshed with the adjacent gear 76, The three clamping rods 6 are fixedly connected to the three racks 79 respectively, and an L-shaped rod 710 is fixedly installed on the side of the circular plate 73 close to the detection machine body 2. A servo motor 2 711 is fixedly installed on the L-shaped rod 710 for driving the adjacent gears 76 to rotate. It should be noted that after the servo motor 2 711 is started, it can drive the corresponding gear 76 to rotate reciprocatingly, and the rotating gear 76 will drive the inner gear ring 74 to rotate, and the rotation of the inner gear ring 74 will drive the three gears 76 to rotate synchronously. The reciprocating rotation of each gear 76 will drive the corresponding rack 79 to reciprocate in a straight line. At this time, each rack 79 drives the sliding rod 78 connected to it to slide back and forth inside the corresponding sliding groove 77. Each rack 79 moves and synchronously drives the clamping rod 6 connected to it to move, so that the three clamping rods 6 are close to or away from each other. The start of the servo motor 1 72 can drive the circular plate 73 to rotate as a whole, so that the three clamping rods 6 and the annular parts fixed by the three clamping rods 6 rotate synchronously.
[0024] like Figure 1 , Figure 3 As shown, two positioning rods 8 in mirror-image distribution are arranged on one side of the vertical plate 5 close to the detection machine body 2, and two groups of transmission mechanisms 9 are arranged on one side of the vertical plate 5 close to the detection machine body 2 for respectively driving the adjacent positioning rods 8 to move up and down, and the two groups of transmission mechanisms 9 are in mirror-image distribution. It should be noted that after the two positioning rods 8 are respectively driven to move to appropriate positions by the two groups of transmission mechanisms 9, when the annular part is placed in the middle of the three clamping rods 6, or when the annular part is sleeved on the three clamping rods 6, the annular part can be fitted with the two positioning rods 8, thereby placing the annular part at an angle to affect the detection.
[0025] like Figure 1 , Figure 3As shown, the transmission mechanism 9 includes a groove 91, and two grooves 91 are provided on the side of the vertical plate 5 close to the detection machine body 2. A servo motor 3 92 is fixedly installed at one end of each groove 91 away from each other, and a screw rod 93 is fixedly installed at the output end of each servo motor 3 92. A movable block 94 is threadedly connected to each screw rod 93, and a rotatable positioning rod 8 is provided on the side of each movable block 94 close to the detection machine body 2. It should be noted that each servo motor 3 92 can drive the corresponding screw rod 93 to reciprocate when started, and the reciprocating rotation of each screw rod 93 will drive the corresponding movable block 94 to move up and down, and the movement of each movable block 94 will synchronously drive the adjacent positioning rod 8 to move.
[0026] like Figure 1 , Figure 3 As shown, each movable block 94 is movably mounted with a damping shaft 95 on one side close to the detection machine body 2, and each damping shaft 95 is fixedly connected to the adjacent positioning rod 8 at one end away from the adjacent movable block 94. It should be noted that when it is not appropriate to use the positioning rod 8 for positioning, the two positioning rods 8 can be rotated one hundred and eighty degrees respectively, and each positioning rod 8 is rotated through the corresponding damping shaft 95, and can be stopped at any angle.
[0027] like Figure 2 As shown, the sides of the three clamping rods 6 that are close to each other are all arranged with a concave arc surface, and the sides of the three clamping rods 6 that are away from each other are all arranged with a convex arc surface. It should be noted that the arc surface can increase the contact area when the three clamping rods 6 clamp or support the annular parts, thereby improving the stability of the fixation.
[0028] In summary:
[0029] First, the staff can determine according to the size of the annular part and choose to fix it by internal support from the inside of the annular part or by clamping from the outside of the annular part. If the internal support type is selected, the annular part can be placed on the outside of the three clamping rods 6, and then the driving mechanism 7 can be controlled to make the three clamping rods 6 move away from each other. Finally, the driving mechanism 7 can be controlled to drive the annular part to rotate at a preset angle and speed. If the clamping type is selected, the annular part can be placed in the middle of the three clamping rods 6, and then the driving mechanism 7 can be controlled to make the three clamping rods 6 move closer to each other. Finally, the driving mechanism 7 can be controlled to drive the annular part to rotate at a preset angle and speed.
