Description

Technical Field

[0001] The utility model relates to the field of fastener removal, in particular to a high-lock bolt removal tool. Background Art

[0002] High-lock bolts are a type of fastener widely used in aviation technology. A large number of high-lock bolts often need to be removed during the daily maintenance of aircraft. The current traditional method of removing high-lock bolts is to use rivet clips and sharp punches. When using rivet clips to impact, a C-type rivet gun is usually used to impact the high-lock bolt to be removed. Since the C-type rivet gun punch needs to be inserted into the bolt hole, the rivet clip is prone to slipping during the rivet gun impact process, resulting in impact on the part and causing damage to the part. The skill requirements for removing the high-lock bolts are high, and the operator must have rich riveting experience. When using a sharp punch to remove, for thicker holes in the parts, the sharp punch is not rigid enough during removal and is easily broken, thereby damaging the hole wall. The sharp punch cannot be used in non-open areas, and the only way to remove the bolts is to drill them out. However, the drilling operation is extremely risky and difficult to operate. Therefore, how to quickly and efficiently remove high-lock bolts in different spaces has become a difficult problem. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a high-lock bolt removal tool, which can be used to efficiently remove high-lock bolts in various spaces.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] The utility model provides a high-lock bolt removal tool, which comprises a hexagonal connector, a round impact rod and a C-shaped riveting gun.

[0006] The C-type rivet gun is used to punch the high-locking bolt to be removed out of the bolt hole, the hexagonal connector is a hexagonal prism with equal cross-section, the round impact rod is a round cylinder with equal diameter, the hexagonal connector is rigidly connected to the round impact rod and the center axis is coaxial, the hexagonal connector is used to pass through the hexagonal cylindrical hole of the high-locking bolt to be removed from the end away from the round impact rod and cooperate with the inner wall gap of the hexagonal cylindrical hole, the end of the round impact rod away from the hexagonal connector is provided with an impact plane A for cooperating to withstand the impact of the C-type rivet gun, the round impact rod is used to pass through the bolt hole of the high-locking bolt to be removed from the end close to the hexagonal connector and cooperate with the inner wall gap of the bolt hole.

[0007] Furthermore, the length of the round impact rod is 10mm-16mm.

[0008] Furthermore, it also includes an extended connecting piece, which includes an extended connecting head and an extended connecting rod. The extended connecting head is an equal-section cylinder, and the extended connecting rod is an equal-diameter cylinder. The extended connecting head is rigidly connected to the extended connecting rod and the center axes are coaxial. The end of the circular impact rod away from the hexagonal connecting head is provided with an extended connecting hole. The extended connecting head of the extended connecting piece is used to pass through the extended connecting hole from the end away from the extended connecting rod and cooperate with the extended connecting hole for connection, such as screw connection. The end of the extended connecting rod away from the extended connecting head is provided with an impact plane B, and the C-type rivet gun impacts on the impact plane B.

[0009] Furthermore, the extended connecting member also includes an intermediate connecting member, which includes an intermediate connecting head and an intermediate connecting rod. The intermediate connecting head is a cylinder of equal cross-section, and the intermediate connecting rod is a cylinder of equal diameter. The intermediate connecting head and the intermediate connecting rod are rigidly connected and coaxial. The intermediate connecting head is used to pass through the extended connecting hole of the circular impact rod from the end away from the intermediate connecting rod and cooperate with the inner wall of the extended connecting hole. The intermediate connecting rod is provided with an intermediate connecting hole at the end away from the intermediate connecting head. The extended connecting head of the extended connecting member is used to pass through the intermediate connecting hole from the end away from the extended connecting rod and cooperate with the inner wall of the intermediate connecting hole.

[0010] Furthermore, there are several intermediate connecting members, and the intermediate connecting head of one intermediate connecting member is also used to pass into the intermediate connecting hole of another intermediate connecting member from an end away from the intermediate connecting rod and cooperate with the inner wall of the intermediate connecting hole.

[0011] Furthermore, the extended connecting head of the extended connecting piece is a screw head, and the extended connecting hole of the round impact rod matched with the extended connecting head is a threaded hole.

[0012] Furthermore, the intermediate connecting head of the intermediate connecting piece is a screw head, and the intermediate connecting hole of the intermediate connecting piece is a threaded hole.

[0013] The beneficial effects of the utility model are:

[0014] The high-lock bolt removal tool provided by the utility model has a round impact rod that starts from one end close to the hexagonal connecting head and enters the bolt hole of the high-lock bolt to be removed and cooperates with the inner wall clearance of the bolt hole. During the removal operation, it can ensure that the high-lock bolt removal tool can pass through the bolt hole smoothly as a whole during the whole process without occupying external space. It is also applicable to non-open areas.

[0015] An impact plane A is provided at one end of the round impact rod away from the hexagonal connector, which is used to cooperate with the impact of the C-type rivet gun. When working, the C-type rivet gun impacts the impact plane A, and the impact force applied is transmitted to the high-locking bolt to be removed through the high-locking bolt removal tool. During operation, the C-type rivet gun does not contact the high-locking bolt to be removed and the bolt hole, which can effectively protect the parts.

[0016] The round impact rod and the hexagonal connector are coaxial, which can make the high-lock bolts evenly stressed during removal.

[0017] The cross-sectional dimensions of the hexagonal connector match the dimensions of the hexagonal columnar hole in the high-locking bolt. When in use, the hexagonal connector cooperates with the inner wall clearance of the hexagonal columnar hole of the high-locking bolt to be removed, which can ensure that the rivet gun does not slip during impact and can stably remove the high-locking bolt.

[0018] The extended connecting hole of the round impact rod is used in conjunction with the extended connecting piece. When the thickness of the interlayer is large, the round impact rod can be impacted by a C-type rivet gun to make it punch into the bolt hole. Then, the extended connecting piece can be used to cooperate with the extended connecting hole to connect and lengthen the tool. If the length of the extended connecting piece is not enough, several intermediate connecting pieces can be used in conjunction to achieve further lengthening until the bolt can be completely punched out of the bolt hole, so that the utility model is applicable to interlayers of different thicknesses.

[0026] The utility model is further described below in conjunction with the accompanying drawings.

[0027] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described below are only used to explain the utility model and are not used to limit the utility model.

[0028] like Figure 1-Figure 3 As shown, the utility model provides a high-lock bolt removal tool, including a hexagonal connector 1 and a round impact rod 2, the hexagonal connector 1 is a cylinder with equal cross-section, the round impact rod 2 is a cylinder with equal diameter, the hexagonal connector 1 and the round impact rod 2 are rigidly connected and the center axes are coaxial, the hexagonal connector 1 is used to insert into the hexagonal cylindrical hole of the high-lock bolt to be removed from the end away from the round impact rod 2 and cooperate with the inner wall gap of the hexagonal cylindrical hole, the hexagonal connector 1 and the inner wall gap of the hexagonal cylindrical hole of the high-lock bolt to be removed can play a positioning effect, ensuring that the tool as a whole is firmly in contact with the high-lock bolt to be removed during the removal work, and no slipping occurs.

[0029] The round impact rod 2 is used to pass through the bolt hole of the high-locking bolt to be removed from one end close to the hexagonal connector 1 and cooperate with the inner wall gap of the bolt hole. When in use, the round impact rod 2 can be extended into the bolt hole of the high-locking bolt to be removed, which can ensure that the tool passes through the hole smoothly, avoiding direct contact between the C-type rivet gun and the high-locking bolt to be removed and the bolt hole, and will not cause damage to the hole and parts. The end of the round impact rod 2 away from the hexagonal connector 1 is provided with an impact plane A for receiving the impact of the C-type rivet gun. Since the tool as a whole can pass through the bolt hole of the high-locking bolt to be removed, it can be used for operations in various spaces.

[0030] Preferably, the length of the round impact rod 2 is 10mm-16mm, and the size of 10mm is the length size of the installation hole of the ordinary high locking bolt in the industry. The utility model can also use a round impact rod 2 with a length less than 10mm, but a length that is too small will result in poor tool rigidity. At the same time, the operator will have inconvenience in using the tool due to the short length. Therefore, it is preferred that the length of the round impact rod 2 is not less than 10mm. At the same time, if the length is too long, it will also result in poor tool rigidity and the rivet gun will easily jump when impacting. Therefore, it is preferred that the length of the round impact rod 2 is 10mm-16mm.

[0031] like Figure 4 , Figure 5As shown, the high-locking bolt removal tool also includes an extended connecting piece 3, and the extended connecting piece 3 includes an extended connecting head and an extended connecting rod. The extended connecting head is an equal-section cylinder, and the extended connecting rod is an equal-diameter cylinder. The extended connecting head and the extended connecting rod are rigidly connected and the center axes are coaxial. The end of the circular impact rod 2 away from the hexagonal connecting head 1 is provided with an extended connecting hole, which is used to cooperate with the extended connecting piece to lengthen the tool in a thicker interlayer. The extended connecting rod is used to pass through the bolt hole of the high-locking bolt to be removed from the end close to the extended connecting head and cooperate with the inner wall of the bolt hole. The end of the extended connecting rod away from the extended connecting head is provided with an impact plane B, which is used to cooperate with the C-type rivet gun to impact. At this time, the C-type rivet gun impacts on the impact plane B, which ensures that the C-type rivet gun is never in contact with the high-locking bolt to be removed and the bolt hole, thereby protecting the parts.

[0032] like Figure 4 , Figure 5 As shown, the extended connector 3 also includes an intermediate connector, which includes an intermediate connector head and an intermediate connector rod. The intermediate connector head is a cylinder of equal cross-section, and the intermediate connector rod is a cylinder. The intermediate connector head is rigidly connected to the intermediate connector rod and the center axes are coaxial. The intermediate connector head of the intermediate connector is used to pass through the extended connecting hole from the end away from the intermediate connecting rod and cooperate with the inner wall of the extended connecting hole. The intermediate connecting rod is provided with an intermediate connecting hole at the end away from the intermediate connector head. The extended connector head of the extended connector 3 is used to pass through the intermediate connecting hole from the end away from the extended connecting rod and cooperate with the inner wall of the intermediate connecting hole. If a thicker interlayer is encountered, the extended connector 3 can be further extended by cooperating with the intermediate connector.

[0033] More preferably, there are several intermediate connecting parts, and the intermediate connecting head of one intermediate connecting part is also used to pass into the intermediate connecting hole of another intermediate connecting part from one end away from the intermediate connecting rod and cooperate with the inner wall of the intermediate connecting hole. When the lengthening of the intermediate connecting hole still does not meet the demand, consider adding several intermediate connecting parts, and cooperate with each other to achieve further lengthening until the high locking bolt is punched out of the bolt hole.

[0034] Preferably, the extended connecting hole of the round impact rod 2 can be selected as a threaded hole, and the extended connecting head of the extended connecting piece 3 is an adaptive threaded connecting head. In the utility model, the extended connecting hole and the extended connecting head can also use the inserted hexagonal and internal hexagonal matching installation method, which is faster and more convenient, but the stability is not as good as the screw connection. Therefore, the extended connecting hole is preferably a threaded hole.

[0035] More preferably, the intermediate connecting head of the intermediate connecting piece is a screw head, and the intermediate connecting hole of the intermediate connecting piece is preferably a threaded hole, and the reasons for preference are the same as those for the extended connecting hole of the extended connecting piece 3.

[0036] The above implementation modes are only preferred implementation modes of the present utility model and do not limit the protection scope of the present utility model. Any equivalent changes or equivalent replacements made to the technical solutions on the basis of the technical solutions of the present utility model shall fall within the protection scope of the present utility model. The specific protection scope shall be subject to the claims.

[0037] The high-lock bolt removal tool provided by the utility model has no limitation on production process and materials. For technicians in this field, the utility model can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
