Description

Technical Field

[0001] The utility model relates to the technical field of drilling processing, in particular to a 90° countersink detection tool. Background Art

[0002] With the continuous advancement of science and technology, the requirements for products are getting higher and higher. Especially for military product parts, due to the stringent technical requirements, cover plate parts with thin walls and good rigidity are widely used in military products. Fitters often encounter the following problems in the process of countersinking the assembly holes of cover plate parts: 1. Affected by factors such as part material, drill bit angle, and machine tool positioning error, the countersink depth is inconsistent, the angle is inaccurate, and other defects are caused. 2. During the self-inspection and testing process, the countersink depth and countersink angle cannot be accurately measured with a caliper. 3. Use screws of corresponding sizes to test whether the countersink meets the requirements, but because the size requirements of the countersink required by the structural design are inconsistent with the size of the screw head, it is difficult to truly reflect whether it meets the requirements of the drawing, causing quality risks to the later assembly.

[0030] The specific implementation of the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the utility model, and is not used to limit the embodiment of the utility model.

[0031] Figure 1 The figure is a three-dimensional view of a 90° countersink inspection tool according to an embodiment of the present invention. In the present invention, the inspection tool may include: an inspection pin 1, a receiving box 2, and a box cover 5. The inspection pin 1 may have a variety of sizes, so that it can be used to inspect whether the sizes of different countersinks meet the requirements, such as Figure 4 Shown is a practical application diagram of the detection measuring nail 1. In the utility model, the upper part of the detection measuring nail 1 can be truncated cone-shaped, and the lower part can be cylindrical, so that it can be placed in a 90° countersunk hole to detect whether the countersunk hole meets the requirements. When the countersunk hole meets the requirements, the detection measuring nail 1 can be placed intact in the countersunk hole. The accommodating box 2 can be used to place the detection measuring nail 1. A accommodating seat 3 can be provided in the accommodating box 2. The accommodating seat 3 can be provided with accommodating holes 4 of multiple sizes, and the accommodating holes 4 can be used to place detection measuring nails 1 of corresponding sizes. The box cover 5 can be hinged on one side of the accommodating box 2, so that the accommodating box 2 can be closed. The detection tool can conveniently and intuitively detect whether the countersunk hole meets the requirements, and is easy to carry.

[0032] In one embodiment of the present invention, Figure 2 and Figure 3As shown, the detection tool may include a U-shaped hole 6. One end of the U-shaped hole 6 may be set at the bottom of the receiving hole 4, and the other end may be set at the side of the receiving hole 4, so each receiving hole 4 may be provided with a U-shaped hole 6. A push rod 7 may be provided in the U-shaped hole 6. One end of the push rod 7 may be set at one end of the U-shaped hole 6, and the other end may be set at the other end of the U-shaped hole 6. A pressing rod 8 may be provided at the other end of the push rod 7. Figure 3 As shown, the pressing rod 8 can exceed the accommodating seat 3, and the material of the push rod 7 can be a bendable material such as iron wire. When the pressing rod 8 is pressed, the push rod 7 can be pressed and moved, and the push rod 7 at one end of the U-shaped hole 6 can move upward, so that the detection nail 1 in the accommodating hole 4 can be lifted up to facilitate the staff to take it.

[0033] In one embodiment of the present invention, Figure 2 As shown, the inspection tool may include a label 9. The label 9 may be arranged on the side of the receiving hole 4, and the size of the inspection nail 1 corresponding to each receiving hole 4 may be marked on the label 9. Because the label 9 is arranged on the side of the receiving hole 4, when the staff needs to inspect the countersunk hole, they can conveniently select a suitable inspection nail 1 according to the mark on the label to inspect the countersunk hole.

[0034] In one embodiment of the present invention, Figure 1 As shown, a buckle 10 may be provided on the side of the box cover 5 away from the hinged connection with the receiving box 2. A slot 11 may be provided on the side of the receiving box 2 away from the hinged connection with the box cover 5. The buckle 10 may be inserted into the slot 11. Due to the arrangement of the buckle 10 and the slot 11, after the box cover 5 is covered on the receiving box 2, the box cover 5 can be stably fixed on the receiving box 2, avoiding the risk of the detection nail 1 in the receiving box 2 being lost.

[0035] In one embodiment of the present invention, Figure 2 As shown, a handle 12 may be provided at one end of the container box 2. The handle 12 can facilitate the staff to carry the detection tool.

[0036] In one embodiment of the present invention, Figure 1 As shown, a protruding pad 13 may be provided in the box cover 5. When the box cover 5 closes the receiving box 2, the protruding pad 13 may be inserted into the receiving box 2 and may support the receiving hole 4, thereby preventing the detection nail 1 in the receiving hole 4 from being separated from the receiving hole 4. A groove 14 corresponding to the pressing rod 8 may be provided on the protruding pad 13. When the protruding pad 13 supports the receiving hole 4, the pressing rod 8 may be accommodated in the corresponding groove 14.

[0037] In one embodiment of the utility model, the side edges of the container box 2 and the box cover 5 may be rounded to prevent workers from colliding with the right-angled edges and getting injured when the sides of the container box 2 and the box cover 5 are right angles, thereby reducing injuries to the workers.

[0038] In one embodiment of the present invention, the receiving holes 4 may be arranged in multiple rows, and the aperture of the receiving holes 4 in each row may be gradually increased according to a certain size, so that the staff can quickly find the detection nails 1 of appropriate sizes.

[0039] Through the above technical scheme, the utility model provides a 90° countersink inspection tool, which is provided with inspection nails of various sizes, and can be used to detect whether the sizes of different countersinks meet the requirements. The storage box can be used to place the inspection nails. A storage seat can be provided in the storage box. The storage seat can be provided with storage holes of various sizes, so that corresponding inspection nails can be placed. The box cover can be hinged on one side of the storage box and can close the storage box. The inspection tool can conveniently and intuitively detect whether the countersink meets the requirements, and is easy to carry.
