Description

Technical Field

[0001] The present application relates to the technical field of power transmission line maintenance, and in particular to a posture error compensation sleeve. Background Art

[0002] Loose bolts are a common problem during power transmission line maintenance. For example, during line connection maintenance, a common problem is loose bolts on overhead jumper connectors. To improve maintenance efficiency and operational safety, assembly tools suitable for threaded connections, such as electric wrenches, have been designed. With the advancement of intelligent technology, the use of robots is becoming increasingly widespread. Therefore, using robots to replace manual labor to tighten loose bolts on overhead jumper connectors has become a research focus.

[0003] However, traditional threaded assembly tools require a stationary state to align, and most operating environments are high in the air, where the wires can sway due to wind, making alignment difficult. Furthermore, traditional threaded assembly tools cannot insert bolt heads or nuts from any angle, requiring the robot to be equipped with a complex recognition system, which is technically difficult, inefficient, and costly to implement. Furthermore, traditional threaded assembly tools are relatively complex in structure and heavy, which limits their overall transportation. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a posture error compensation sleeve to solve the technical problems of traditional threaded connection assembly tools, such as difficulty in alignment, inability to insert bolt heads or nuts from any angle, and complex structure and high mass.

[0005] To achieve the above technical objectives, the present application provides a posture error compensation sleeve, including a cylinder, an angle finder, a driving member, an elastic member and a limit member;

[0006] One end of the cylinder is provided with a first matching cavity along its own axial direction, and the other end is provided with a second matching cavity along its own axial direction;

[0007] A partition structure is provided in the cylinder body for separating the first matching cavity from the second matching cavity;

[0008] The angle finder is rotatably mounted on one end of the cylinder and is provided with a guide hole communicating with the first matching cavity;

[0009] The driving member is movably installed in the second matching cavity along the axial direction of the cylinder and is synchronously rotated with the cylinder;

[0010] The elastic member is connected between the driving member and the partition structure;

[0011] The limiting member is mounted on the cylinder body and is used to limit the driving member in the second matching cavity;

[0012] The limiting member is provided with an avoidance hole for a structure cooperating with the driving member to extend into.

[0013] Furthermore, the cylinder is a hexagonal sleeve;

[0014] The first matching cavity is a hexagonal cavity;

[0015] The second matching cavity is a quadrangular cavity.

[0016] Furthermore, a concave hole is provided on a side of the driving member away from the partition structure.

[0017] Furthermore, the driving member is a square rivet;

[0018] The structure that cooperates with the driving member is a square tenon.

[0019] Furthermore, the elastic member is a spring.

[0020] Furthermore, a first annular groove for inserting one end of the elastic member is provided on a surface of the partition structure facing the driving member;

[0021] A second annular groove for the other end of the elastic member to be embedded in is provided on a side of the driving member facing the partition structure.

[0022] Furthermore, the limiting member is a clip spring;

[0023] A clamping groove is provided on the second matching cavity near the other end of the cylinder;

[0024] The clamping spring is installed on the clamping slot.

[0025] Furthermore, the partition structure is provided with a connecting hole connecting the first matching cavity and the second matching cavity.

[0026] Furthermore, a third annular groove is provided on the outer peripheral surface of the cylinder near one end;

[0027] The angle finder is rotatably mounted on the barrel section between the third annular groove and one end of the barrel;

[0028] A plurality of triangular guide teeth are arranged in a circumferential array on the guide hole.

[0029] Furthermore, the angle finder is detachably connected to the cylinder and comprises two semicircular clamping parts;

[0030] The two clamps are rotatably clamped on the barrel section between the third annular groove and one end of the barrel.

[0031] It can be seen from the above technical solutions that the posture error compensation sleeve designed in this application, through the design of an angle finder that rotates with the cylinder and has a guide hole connected to the first matching cavity, can allow the contacted bolt head / nut to extend in an adaptive posture, and when the cylinder is driven by the driving member to the point where the first matching cavity and the bolt head / nut are just aligned, the first matching cavity can be quickly sleeved on the bolt head / nut under the action of the elastic member, which is convenient for alignment and can be inserted from any angle. The efficiency is high, which helps to reduce the complexity of the recognition system and thus save costs. In addition, the overall structure of the sleeve designed is simple and compact, and the volume and mass are also optimized, which can be better matched with the robot to achieve the purpose of lightweighting and better applicability.

[0045] An embodiment of the present application discloses a posture error compensation sleeve.

[0046] See also Figures 1 to 3 , an embodiment of the posture error compensation sleeve provided in the embodiments of the present application includes:

[0047] Cylinder 1, angle finder 5, driving member 3, elastic member 2 and limiting member 4.

[0048] The cylinder 1 has a first mating cavity 11 at one end along its axial direction and a second mating cavity 12 at the other end along its axial direction. The first mating cavity 11 is used to engage with an inserted bolt head or nut 7 to achieve screwing of the bolt head or nut 7. The second mating cavity 12 is used to engage with the driving member 3.

[0049] A partition structure 13 is provided in the cylinder 1 for separating the first matching cavity 11 from the second matching cavity 12 . The partition structure 13 can be integrally formed with the cylinder 1 , and there is no specific limitation thereto.

[0050] The angle finder 5 is rotatably mounted on one end of the cylinder 1 and is provided with a guide hole connected to the first matching cavity 11; the setting of the guide hole allows the bolt head or nut 7 to be quickly inserted into the angle finder 5. When inserted, the bolt head or nut 7 is not necessarily aligned with the first matching cavity 11, but because the angle finder 5 and the cylinder 1 are rotationally matched, the cylinder 1 itself can adjust the position of the first matching cavity 11 by rotation until the first matching cavity 11 is aligned with the bolt head or nut 7.

[0051] The driving member 3 is movably installed in the second matching cavity 12 along the axial direction of the cylinder 1, and is connected to the cylinder 1 for synchronous rotation; the elastic member 2 is connected between the driving member 3 and the partition structure 13 to provide an elastic force; the limiting member 4 is installed on the cylinder 1 to limit the driving member 3 in the second matching cavity 12; the limiting member 4 is provided with an avoidance hole for the structure matching with the driving member 3 to extend into.

[0052] During use, the structure that cooperates with the driving member 3 is inserted into the second matching cavity 12 through the avoidance hole and cooperates with the driving member 3. By driving the driving member 3 to rotate, the barrel 1 is synchronously driven to rotate, so that the angle of the first matching cavity 11 can be adjusted so that the first matching cavity 11 is aligned with the bolt head or nut 7. The driving member 3 is driven to rotate while the elastic member 2 is compressed. In this way, when the barrel 1 rotates to the first matching cavity 11 and cooperates with the bolt head or nut 7, the elastic force of the elastic member 2 can be used to quickly extend the bolt head or nut 7 into the first matching cavity 11.

[0053] It can be seen from the above technical solutions that the posture error compensation sleeve designed in this application, by designing an angle finder 5 that rotates with the cylinder 1 and has a guide hole connected to the first matching cavity 11, can allow the contacted bolt head / nut 7 to extend in an adaptive posture, and when the cylinder 1 is driven by the driving member 3 to the point where the first matching cavity 11 and the bolt head / nut 7 are just aligned, the first matching cavity 11 can be quickly sleeved on the bolt head / nut 7 under the action of the elastic member 2, which is convenient for alignment and can be inserted from any angle. The bolt head / nut 7 is highly efficient and helps reduce the complexity of the recognition system, thereby saving costs. In addition, the overall structure of the sleeve designed is simple and compact, and the volume and mass are also optimized, which can be better matched with the robot to achieve the purpose of lightweighting and better applicability.

[0054] The above is the embodiment 1 of the posture error compensation sleeve provided in the embodiment of the present application. The following is the embodiment 2 of the posture error compensation sleeve provided in the embodiment of the present application. For details, please refer to Figures 1 to 8 .

[0055] Based on the solution of the above embodiment 1:

[0056] Further, if Figure 4 as well as Figure 5 As shown, taking the common hexagonal bolt head or hexagonal nut 7 as an example, the cylinder 1 can be a hexagonal sleeve, and correspondingly, the first matching cavity 11 is a hexagonal cavity, and the second matching cavity 12 is a square cavity.

[0057] Furthermore, in order to facilitate the connection and cooperation between the driving member 3 and the corresponding matching structure, a concave hole is provided on a side of the driving member 3 away from the separation structure 13.

[0058] Furthermore, the driving member 3 can be designed as a square rivet; correspondingly, as Figure 7 as well as Figure 8 As shown, the structure that cooperates with the driving member 3 is designed as a square tenon 8.

[0059] Furthermore, the elastic member 2 is preferably designed as a spring.

[0060] Further, if Figure 5 As shown, taking the spring design as an example, for ease of installation, a first annular groove 15 for embedding one end of the elastic member 2 is provided on the side of the partition structure 13 facing the driving member 3; correspondingly, as shown Figure 1 As shown, a second annular groove 31 is provided on a surface of the driving member 3 facing the partition structure 13 for the other end of the elastic member 2 to be embedded in.

[0061] Furthermore, the limiting member 4 is preferably designed as a clip, taking this as an example:

[0062] A clamping groove 16 is provided on the second matching cavity 12 near the other end of the cylinder 1 , and a clamping spring is installed on the clamping groove 16 . This design makes installation and disassembly easy.

[0063] Further, if Figure 3 As shown, the partition structure 13 is provided with a connecting hole 17 that connects the first mating cavity 11 and the second mating cavity 12. Specifically, the partition structure 13 can be an annular flange, with a through hole in the middle forming the connecting hole 17. The connecting hole 17 is designed to allow the end of the bolt 6 to pass through. In this way, even if the portion of the bolt 6 protruding from the nut 7 is longer than the first mating cavity 11, the cylinder 1 can still effectively fit the nut 7. The connecting hole 17 provides an extended area for the end of the bolt 6, improving its applicability.

[0064] Further, if Figure 4 as well as Figure 5 As shown, in order to facilitate the installation and arrangement of the angle finder 5, a third annular groove 14 is provided on the outer circumference of the cylinder 1 near one end, and the angle finder 5 is rotatably mounted on the cylinder section between the third annular groove 14 and one end of the cylinder 1.

[0065] The guide hole has a plurality of triangular guide teeth 511 arranged in a circular array. This design of guide teeth 511 allows the angle finder 5 to better adapt to its position when contacting the hexagonal bolt head / nut 7, making it easier to insert the bolt head / nut 7 and further enhancing the guiding effect. Taking the guide hole as an example of a countersunk hole design with a conical surface and a cylindrical surface, the guide teeth 511 also have two sides: the first layer is arranged at an angle on the conical surface of the guide hole, and the second layer is arranged on the cylindrical surface of the guide hole. There is no specific limitation.

[0066] Furthermore, in order to facilitate disassembly and maintenance, the angle finder 5 and the cylinder body 1 are detachably connected and specifically include two semicircular clamps 51. The structure of the clamps 51 can be designed with reference to the clamp structure.

[0067] The two clamps 51 are rotatably clamped on the barrel 1 at the barrel section between the third annular groove 14 and one end of the barrel 1. The two clamps 51 are fastened together by fasteners such as screws, which are not specifically limited.

[0068] like Figure 7 as well as Figure 8 As shown, the use process of the sleeve provided by this application is as follows:

[0069] 1. During the tightening process of the bolt 6, the square tenon 8 rotates while pushing the cylinder 1 toward the bolt 6. When the angle finder 5 touches the nut 7, the angle finder 5 will continue to rotate to increase the feed amount, adapt to the angle of the nut 7 and clamp the nut 7.

[0070] 2. When the nut 7 is inserted into the angle finder 5, the nut 7 and the cylinder 1 are already in a concentric state, but the angles between the nut 7 and the first matching cavity 11 of the cylinder 1 may not correspond. The cylinder 1 will press against the nut 7 and the square tenon 8 will continue to rotate and move forward, thereby compressing the elastic part 2 in the cylinder 1.

[0071] 3. When the cylinder 1 is rotated until the first matching cavity 11 is aligned with the nut 7, the compressed spring will push the cylinder 1 to cover the nut 7 so that it is completely covered; continue to rotate the cylinder 1 to drive the nut 7 to rotate, thereby tightening the bolt 6.

[0072] The above is a detailed introduction to the posture error compensation sleeve provided in this application. For general technicians in this field, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on this application.
