DETAILED DESCRIPTION

[0019] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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.

[0020] like Figure 1-4 As shown, a wall thickness gauge for a Hejie ring comprises: an inspection platform 1, an inner diameter limiting sleeve 3 is arranged on the upper end surface of the inspection platform 1, and a vertical plate 4 is fixedly arranged on the upper end surface of the inspection platform 1 and near one end.

[0021] A motor 6 is fixedly installed inside the vertical plate 4, and a screw rod 5 is rotatably installed inside the vertical plate 4. The end of the screw rod 5 is fixedly connected to the output shaft of the motor 6. A slide plate 7 is threadedly connected to the screw rod 5. A slide groove is opened on one side of the vertical plate 4. The size of the slide groove is adapted to the movement trajectory of the slide plate 7. The slide plate 7 passes through the slide groove and extends to the outside.

[0022] The side of the slide plate 7 away from the vertical plate 4 is fixedly connected to a fixed shaft 8, and a cavity 10 is opened inside the fixed shaft 8 and near the lower end. Connecting rods 11 are slidably connected to both sides of the fixed shaft 8. One end of the connecting rod 11 passes through the side wall of the fixed shaft 8 and extends into the cavity 10, and the other end of the connecting rod 11 extends to the outside and is fixedly connected to an outer diameter limit block 9. The upper and lower sides of the connecting rod 11 are fixedly connected to fixing plates 13, and the side of the fixing plate 13 is fixedly connected to a spring 12, and the other end of the spring 12 is fixedly connected to the inner wall of the fixed shaft 8. The end face of the connecting rod 11 inside the cavity 10 is an inclined face.

[0023] The lower end of the outer diameter limiting block 9 is provided with an arc groove.

[0024] The bottom end of the fixed shaft 8 is threadedly connected with a screw rod 14, which passes through the side wall of the fixed shaft 8 and extends into the cavity 10. The end of the screw rod 14 inside the cavity 10 is fixedly connected with a top block 15, which is conical and fits the end face of the connecting rod 11.

[0025] The distance between the two outer diameter limit blocks 9 can be changed according to the size of the Jiehuan body 2, so that the distance between the two outer diameter limit blocks 9 is adapted to the outer ring size of the Jiehuan body 2: the screw 14 is turned upward, and the screw 14 drives the top block 15 to rotate upward, and the top block 15 squeezes the connecting rods 11 on both sides, so that the connecting rods 11 on both sides move in opposite directions. During this process, the spring 12 is compressed until the distance between the two outer diameter limit blocks 9 is adapted to the outer ring size of the Jiehuan body 2, and then the screw 14 is stopped.

[0026] The inner diameter limiting sleeve 3 includes a plurality of collars 31 of different sizes. A collar 31 of larger size is sleeved on the outside of a collar 31 of smaller size, and there is no gap between two adjacent collars 31 . All collars 31 are coaxially arranged.

[0027] Working principle:

[0028] According to the different sizes of the Hejie ring body 2, take out or install the ring 31 of the corresponding size according to the size of the Hejie ring body 2, align the inner ring of the Hejie ring body 2 with the outer ring of the inner diameter limiting sleeve 3 and place the Hejie ring body 2 at the bottom of the inner diameter limiting sleeve 3, so that there is no gap between the inner ring of the Hejie ring body 2 and the outer ring of the inner diameter limiting sleeve 3;

[0029] The screw 14 is rotated upward, and the screw 14 drives the top block 15 to rotate upward. The top block 15 squeezes the connecting rods 11 on both sides, so that the connecting rods 11 on both sides move in opposite directions. During this process, the spring 12 is compressed until the distance between the two outer diameter limit blocks 9 is adapted to the outer ring size of the fast ring body 2, and the screw 14 stops rotating;

[0030] Start the motor 6, which drives the screw 5 to rotate, so that the slide plate 7, the fixed shaft 8, and the two outer diameter limit blocks 9 move downward as a whole, until the outer diameter limit blocks 9 are moved to the upper end surface of the inspection platform 1. If the Hejie ring body 2 is between the arc grooves of the two outer diameter limit blocks 9, it means that the wall thickness of the Hejie ring body 2 is within the tolerance range, otherwise it is unqualified.

[0031] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
