Abstract
Description
Technical Field
[0001] The present application relates to the technical field of thread detection, and in particular to a screw thread detection device. Background Art
[0002] At present, screw thread detection usually adopts thread ring gauge for measurement. According to the thread specification to be measured, the corresponding thread ring gauge is selected, and the thread ring gauge is placed in the screw thread to ensure that the thread ring gauge can be screwed in smoothly. Then the thread ring gauge is screwed into the screw thread counterclockwise and then screwed out clockwise. When the process of screwing in and out of the ring gauge is smooth, the inspection is qualified.
[0003] There are some fully automatic screw thread detection equipment on the market. This type of equipment has a high degree of automation and is suitable for the detection of large quantities of screw threads. However, the structure is complex and the production cost is high. At present, for the detection of a small number of screw threads, the thread ring gauge is still directly rotated by hand to make the thread ring gauge rotate counterclockwise into the screw thread and then rotated out clockwise. However, when the thread ring gauge is directly rotated by hand, the thread ring gauge rotates slowly and the screw thread detection efficiency is low. Summary of the invention

[0006] Furthermore, the first gear set includes a first rotating shaft, a first driven gear and a second driven gear, the first rotating shaft is rotatably disposed on the mounting seat, the first driven gear and the second driven gear are both fixed on the first rotating shaft, the mounting seat is located between the first driven gear and the second driven gear, and the end of the cylinder away from the ring gauge is fixedly connected to the first rotating shaft.

[0008] Furthermore, the third gear set includes a third rotating shaft, a first driving gear and a second driving gear. The third rotating shaft is rotatably arranged on the mounting seat. The first driving gear and the second driving gear are respectively fixed at two ends of the third rotating shaft. The first driving gear is meshed with the first transmission gear, and the second driving gear is meshed with the second transmission gear.
[0009] Furthermore, the rotating handle is fixedly arranged on a side of the first driving gear away from the third rotating shaft.
[0010] Beneficial effects of the utility model:
[0011] The utility model is connected by transmission between the first gear group and the second gear group, and the second gear group and the third gear group. The third gear group is driven to rotate by rotating the handle to drive the second gear group to rotate, and the second gear group drives the third gear group to rotate. The diameter of the gears in the first gear group is smaller than the diameter of the gears in the second gear group, and the diameter of the gears in the second gear group is smaller than the diameter of the gears in the third gear group, so that the rotation speed of the first gear group is greater than the rotation speed of the third gear group, thereby increasing the rotation speed of the cylinder, and then increasing the rotation speed of the ring gauge, so that the speed of the ring gauge being screwed into the screw thread or screwed out of the screw thread is faster, thereby improving the detection efficiency of the screw thread.

Since the gear diameter in the first gear set 2 is smaller than the gear diameter in the second gear set 3, and the gear diameter in the second gear set 3 is smaller than the gear diameter in the third gear set 4, the rotation speed of the first gear set 2 is greater than that of the third gear set 2, thereby increasing the rotation speed of the cylinder 5, and then increasing the rotation speed of the ring gauge 6, so that the ring gauge 6 can be screwed into the screw thread or screwed out of the screw thread faster, thereby improving the detection efficiency of the screw thread.
[0025] like Figure 1 and Figure 2 As shown, the first gear set 2 includes a first rotating shaft 21, a first driven gear 22 and a second driven gear 23. The first rotating shaft 21 is rotatably arranged on the mounting base 1. The first driven gear 22 and the second driven gear 23 are both fixedly arranged on the first rotating shaft 21. The mounting base 1 is located between the first driven gear 22 and the second driven gear 23. The end of the cylinder 5 away from the ring gauge 6 is fixedly connected to the first rotating shaft 21.

If the process of screwing the ring gauge 6 in and out is smooth, the test is qualified.
[0031] The above are only preferred embodiments of the present application and are not intended to limit the present application.
