Embodiment
For the utility model is become apparent, now with a preferred embodiment, and conjunction with figs. is described in detail below.
As shown in Figure 1, the utility model provides a kind of screw thread of self body gravity that relies on to examine machine entirely, comprise upper plate 1 and lower plate 2, workpiece locating piece 9 is fixed on the workpiece with internal thread hole 10 to be measured on the upper plate 1, between upper plate 1 and lower plate 2, fix two linear guides 3, be with a slide block on every linear guide 3, the two ends of last lower moving plate 4 fix with a slide block respectively, and going up lower moving plate 4 like this can move up and down on linear guide 3.Be with a support spring 5 respectively in the bottom of every linear guide 3, when equipment does not start, to go up lower moving plate 4 by support spring 5 and be supported on an initial position, at this moment, be positioned at lower moving plate 4 other original position sensors 12 and provide signal, above original position sensor 12, also have the qualified sensor 11 of part.
A minitype speed reducing motor 6 is installed in the bottom of last lower moving plate 4, and screw thread detection head 8 is installed in the top of lower moving plate 4 by screw thread detection head fixed cover 7, drives screw thread detection heads 8 by minitype speed reducing motor 6 and rotates.End at this screw thread detection head 8 has screw thread, this screw thread can with the internal thread interlock mutually of the workpiece with internal thread hole 10 to be measured, the thread head of opening of this screw thread detection head 8 partly protrudes in upper plate 1.
The course of work of the present utility model is: the workpiece with internal thread hole 10 to be measured is fixed on the upper plate 1 by workpiece locating piece 9, the internal thread hole of workpiece 10 is aimed at screw thread detection head 8, this moment screw thread detection head 8 tops the part screw thread with the screw thread generation interlock of the internal thread hole bottom of workpiece 10, at this moment, last lower moving plate 4 is positioned at initial position, original position sensor 12 provides signal, shows that promptly workpiece 10 is in place.Minitype speed reducing motor 6 starts, drive 8 rotations of screw thread detection head, screw thread detection head 8 is in the process of the internal thread hole that is threaded into workpiece 10, produce power upwards, lower moving plate 4 moves upward in the drive, when last lower moving plate 4 moves to the qualified sensor of part 11 positions, the qualified sensor 11 of this part sends signal, and then the screw thread of this workpiece 10 is qualified.If the screw thread of workpiece 10 is defective, then the qualified sensor 11 of part can not send letter all the time, if surpass a certain setting-up time, does not also receive the signal of the qualified sensor 11 of part, judges that then the screw thread of this workpiece 10 is defective.
The utility model makes full use of the own characteristic of screw thread, when screw thread detection head 8 rotates, produces pulling force upwards, and last lower moving plate 4 moves upward.Stablize in order to ensure each the detection, last lower moving plate 4 is installed on the support spring 5, by regulating the anchorage force of support spring 5, makes lower moving plate 4 be in suspended state, guarantees to contact with the reliable of workpiece 10.
