Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] refer to Figure 1-2 As shown, the utility model provides a novel blind hole automatic thread inspection gauge device, comprising: an equipment body 1 with a processing position on the top, a workpiece seat 9, a lifting mechanism and an external thread gauge 13 are arranged on the processing position from top to bottom, a motor 15 for driving the external thread gauge 13 to rotate is arranged in the equipment body 1, the workpiece seat 9 is a hollow structure, and the workpiece seat 9 is used to clamp and position the workpiece, and the lifting mechanism is used to drive the workpiece seat 9 to move closer to or away from one side of the external thread gauge 13.

[0031] As described above, when using the equipment body 1, workpiece seat 9, lifting mechanism, external gauge 13 and motor 15 provided by the utility model, the external gauge 13 is rotatably installed on the top of the equipment body 1 by the motor 15, and the workpiece seat 9 is suspended above the external gauge 13 by the lifting mechanism. The workpiece seat 9 is a hollow structure, and a positioning groove for the workpiece is provided in the workpiece seat 9. When the workpiece is placed in the workpiece seat 9, the blind hole at the bottom of the workpiece is on the axis line above the external gauge 13. At the same time, the workpiece cannot rotate in the workpiece seat 9 through the positioning groove. The workpiece is pressed downward, and the blind hole at the bottom of the workpiece is brought close to the external gauge 13 by the lifting mechanism. When the external gauge 13 is normally screwed into the blind hole, the workpiece is qualified, otherwise it is unqualified.

[0032] Further, in order to facilitate the lifting and lowering adjustment of the workpiece seat 9 above the external tooth gauge 13, refer to Figure 2 As shown, the lifting mechanism includes a support plate 10 and lifting rods 11 symmetrically installed on both sides of the bottom of the support plate 10, the workpiece seat 9 is set through the top of the support plate 10, the bottom ends of the two lifting rods 11 are movably extended to the inside of the equipment body 1, and two springs 12 are respectively sleeved on the lifting rods 11 on both sides between the support plate 10 and the equipment body 1. The support plate 10 is suspended above the external tooth gauge 13 through the lifting rods 11 and the springs 12. The support plate 10 can be raised and lowered above the external tooth gauge 13 by the elastic force of the springs 12. In the process of lifting and lowering the support plate 10, it is lifted and guided by the lifting rods 11.

[0033] In the present utility model, combined with Figure 1-2 As shown, one side of the support plate 10 of this embodiment is also provided with a limiting mechanism for limiting the lifting height.

[0034] Combination Figure 4-6 As shown, the limiting mechanism includes a vertical plate 2, a lifting plate 6, a positioning block 3 and a limiting block 5. The bottom of the vertical plate 2 can be detachably mounted on the top of the equipment body 1, the lifting plate 6 is lifted and mounted on the vertical plate 2, the positioning block 3 can be detachably mounted on the side of the lifting plate 6 close to the support plate 10, the limiting block 5 can be detachably mounted on the side wall of the support plate 10, and at least a portion of the limiting block 5 abuts against the top of the positioning block 3.

[0035] As mentioned above, when using the limiting mechanism provided by the utility model, the positioning block 3 in the limiting mechanism is arranged on one side of the support plate 10 through the vertical plate 2 and the lifting plate 6. At this time, the positioning block 3 is at the ultimate position for workpiece detection. When the support plate 10 drops to the lowest position, the limiting block 5 on the support plate 10 abuts against the positioning block 3 to prevent the external tooth gauge 13 from being locked with the workpiece.

[0036] Further, in order to facilitate the height adjustment of the lifting plate 6, refer to Figure 4As shown, the lifting plate 6 is penetrated with a moving groove 4 in the longitudinal direction, and a fastening bolt 20 extending into the moving groove 4 is provided on the side of the lifting plate 6 away from the vertical plate 2. A threaded hole 14 for accommodating the fastening bolt 20 is provided on the vertical plate 2. When the fastening bolt 20 abuts against the lifting plate 6, the lifting plate 6 is restricted from being lifted and lowered on the vertical plate 2. The fastening bolt 20 is loosened, and the lifting plate 6 is lifted and lowered on the vertical plate 2 through the moving groove 4, thereby adjusting the height of the positioning block 3. When the positioning block 3 reaches a predetermined position, the fastening bolt 20 is tightened to fasten the lifting plate 6 to the vertical plate 2.

[0037] In the present utility model, combined with Figure 2 As shown, one side of the support plate 10 of this embodiment is also provided with a trigger component for changing the rotation speed of the external tooth gauge 13.

[0039] As mentioned above, when using the trigger assembly provided by the utility model, the mounting plate 8 in the trigger assembly provides an installation position for the infrared sensor 7 on one side of the support plate 10. When the support plate 10 descends, the identification block 19 on the support plate 10 will pass through the infrared sensor 7. At this time, the infrared sensor 7 sends an electrical signal to the motor 15 to reduce the speed of the motor 15, thereby achieving the low-speed tightening of the external tooth gauge 13 to the workpiece.

[0040] Further, in order to facilitate the height adjustment of the infrared sensor 7, refer to Figure 3 As shown, the mounting plate 8 is longitudinally penetrated with a lifting groove 18, the infrared sensor 7 is penetrated and arranged in the lifting groove 18, and the infrared sensor 7 is provided with a retaining ring 16 and a nut 17 clamped in the lifting groove 18 in sequence, the retaining ring 16 is welded on the infrared sensor 7, and the nut 17 is threaded on the infrared sensor 7.
