[0018] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0019] A device for inspecting the dimensions of semi-finished surge arrester insulators, such as Figs. 1-2As shown, it includes a base 1, an inspection base 2 mounted on the base 1, and an inspection component movably mounted on one side of the inspection base 2. A short rod positioning groove 3 is provided on one side of the upper surface of the inspection base, and a long rod positioning groove 4 is provided on the other side of the upper surface of the inspection base. A gap groove 5 is provided between the short rod positioning groove 3 and the long rod positioning groove 4. The inspection component includes a detection drive and a detection plug 6. The output end of the detection drive is connected to one end of the detection plug 6 and drives the detection plug 6 to move closer to or away from the inspection base. A detection groove 7 is provided at the end of the detection plug 6 near the inspection base, and the detection groove 7 corresponds to the short rod positioning groove 3. The inspection base also has a placement groove 8, with both ends of the placement groove 8 communicating with the short rod positioning groove 3 and the long rod positioning groove 4, respectively. The short rod positioning groove 3 and the long rod positioning groove 4 are perpendicular to the placement groove 8. The depth of the short rod positioning groove 3 is greater than the depth of the long rod positioning groove 4. Specifically, this utility model has a novel structure. In this embodiment, an interval groove 5 is provided between the short rod positioning groove 3 and the long rod positioning groove 4. This means that the distance between the two electrode rods (generally one electrode is a long rod and the other a short rod) is the length of the interval groove 5 (e.g., 85±0.5mm). During operation, the semi-finished surge arrester insulator to be inspected is placed in the placement groove 8. Simultaneously, one electrode (the long rod portion) is placed in the long rod positioning groove 4 for positioning, while the other electrode (the short rod portion) is placed in the short rod positioning groove 3. If the other electrode (the short rod portion) cannot be placed in the short rod positioning groove 3, it indicates that the semi-finished insulator is unqualified. If the other electrode (the short rod portion) cannot be placed in the short rod positioning groove 3, it indicates that the semi-finished insulator is unqualified. If the test block 6 can be placed into the short rod positioning slot 3, the detection drive will be activated to drive the test block 6 to approach and insert into the short rod positioning slot 3. The other electrode (short rod part) will be inspected through the detection slot 7 of the test block 6. If the test block 6 collides with the other electrode (short rod part), it is a defective product. If the other electrode (short rod part) enters the detection slot 7 when the test block 6 is inserted into the short rod positioning slot 3, the product can be judged as qualified. After the surge arrester insulator semi-finished product is qualified after being inspected in the above way, it will be placed into the mold for injection. The sheath will not be eccentric, ensuring that the outer circumference thickness of the sheath is consistent, improving the product qualification rate, and increasing the product reliability. This is conducive to improving production efficiency and reducing production costs.

[0020] In this embodiment, a limiting block 9 is provided on one side of the short rod positioning groove 3, and an opening 10 is provided on the lower front side of the limiting block 9 for the detection plug 6 to pass through. Specifically, the limiting block 9 corresponds to the position of the detection groove 7. Under this arrangement, when the detection plug 6 is inserted into the short rod positioning groove 3, if the surge arrester insulator semi-finished product is a qualified product, after the limiting block 9 passes through the detection groove 7, the detection plug 6 is inserted into the short rod positioning groove 3 from the opening 10, and the other electrode (short rod part) of the surge arrester insulator semi-finished product enters the detection groove 7. The limiting block 9 can play a limiting role to ensure that the stroke of the detection plug 6 is correct.

[0021] In this embodiment, the detection drive includes a cylinder 11 and a slider 12. The slider 12 is slidably disposed on the base 1. The output end of the cylinder 11 is connected to one end of the slider 12, and the other end of the slider 12 is connected to one end of the detection plug 6. The cylinder 11 is used to drive the slider 12 to move back and forth, thereby driving the detection plug 6 to move back and forth. The base 1 is also provided with a limiting groove 13, and the lower end face of the slider 12 is slidably connected to the limiting groove 13. Specifically, under the above configuration, the cylinder 11 drives the slider 12 to move back and forth reciprocally, thereby driving the detection plug 6 to move back and forth reciprocally, facilitating the movement of the detection plug 6 to detect whether the surge arrester insulator semi-finished product is qualified.
