[0029] The utility model embodiments will be described below with the accompanying drawings of the utility model embodiments. Figures 1-8 The technical solutions in the embodiments of the utility model are clearly and completely described, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0030] In order to solve the problem that the signal tooth 9 consumes a long time in angle alignment during installation in the prior art, the embodiment provides a signal tooth installation tool, which comprises a positioning part 3, the positioning part 3 is provided with a sink groove for placing the signal tooth 9, the sink groove is open at the bottom end, the outer edge surface of the sink groove is provided with an embedding groove 5 for clamping the tooth of the signal tooth 9, the end surface of the positioning part 3 is provided with a guide rod 2, and the assembly part 1 is provided with a process hole 8 matched with the guide rod 2.
[0031] According to the above technical solution:
[0032] When in use, a tooth of the signal tooth 9 corresponds to the embedding groove 5, and the signal tooth 9 is embedded into the sink groove vertically. Under the cooperation of the embedding groove 5 and the tooth, the signal tooth 9 cannot be deflected on the positioning part 3. The tooling and the signal tooth 9 are heated together, the interference assembly installation problem is solved by using the temperature difference method, and the signal tooth 9 is more labor-saving in assembly.
[0033] After heating, the tooling and the signal tooth 9 are integrally close to the assembly part 1, and the shaft of the assembly part 1 penetrates through the positioning part 3 and the signal tooth 9. The guide rod 2 is opposite to the process hole 8 of the assembly part 1 and is inserted into the process hole 8. Through the cooperation between the guide rod 2 and the process hole 8 and between the embedding groove 5 and the tooth of the signal tooth 9, the installation of the signal tooth 9 is quickly guided, so that the center of the signal tooth 9 is basically aligned with the shaft of the assembly part 1. Then the tooling is pushed again to be close to the assembly part 1, and due to the principle that the straight line between two points is the shortest, the tooling guides the signal tooth 9 to be installed on the assembly part at a correct angle.
[0034] After reaching the installation position, the positioning part 3 is pushed backward, the positioning part 3 is separated from the signal tooth 9, and is taken off from the shaft of the assembly part 1, at this time, the signal tooth 9 and the shaft of the assembly part 1 are installed together at a correct angle.
[0035] In this embodiment, the positioning member 3 is a ring-shaped member with inner and outer rings parallel, forming an angle positioning ring. The side of the positioning member 3 away from the guide rod 2 is fixedly installed with an end cover 4 by screws, and the axis of the end cover 4 is provided with a insertion hole. The through hole type component is easier to process. The diameter of the insertion hole is larger than the diameter of the mounting hole of the signal tooth 9. So that the end cover 4, the positioning member 3 and the shaft of the assembly part 1 are not in contact, so as to avoid the backward resistance when the tool is disassembled.
[0036] In this embodiment, the outer edge surface of the sink is consistent with the outer edge surface of the tooth of the signal tooth 9. So that the signal tooth 9 will not shake due to the gap after being embedded in the sink, causing the installation angle to deviate.
[0037] In this embodiment, the embedded groove 5 includes two partitions spaced apart on the outer edge surface of the sink. The two partitions are arranged towards the axis of the positioning member 3, and an open channel is framed on the side wall of the sink through the two partitions, which is the embedded groove 5.
[0038] In this embodiment, the guide rod 2 is a variable diameter rod, and the diameter of the end connected with the positioning member 3 is larger than the diameter of the suspended end. When installing, the guide rod 2 is inserted into the process hole 8, so as to align the installation angle; continue to push the tool, which will drive the signal tooth 9 to move on the shaft of the assembly part 1, until the variable diameter end 7 of the guide rod 2 abuts against the end surface of the process hole 8, which is the installation position corresponding to the signal tooth 9. So during installation, it is not necessary to measure the feeding size one by one, only need to install the variable diameter end 7 of the guide rod 2 abutting against the process hole 8. Simplify the installation process, make the assembly more convenient.
[0039] In this embodiment, the guide rod 2 and the process hole 8 are chamfered. It is convenient for the guide rod to be inserted.
[0040] In this embodiment, the depth of the sink is less than the thickness of the signal tooth 9. So that one end of the signal tooth 9 is exposed outside the sink. When the signal tooth 9 is installed incorrectly on the positioning member 3, or the signal tooth 9 is embedded in the sink and then found to have a problem such as chipping, it is convenient to pry out.
[0041] In this embodiment, the guide rod 2 is detachably installed on the positioning member 3. The end surface of the positioning member 3 is provided with an eaves part, the eaves part is provided with a threaded hole 6, and the installation end of the guide rod 2 is provided with an external thread. Through the cooperation of the threaded hole 6 and the external thread, the guide rod 2 and the positioning member 3 are detachably connected. The detachable connection of the guide rod 2 and the positioning member 3 is relative to the integrated design; not only easier to process, but also the guide rod 2 can be replaced individually after being damaged during the guiding process.
[0042] In this embodiment, the number of embedded grooves 5 is at least one. To ensure that at least one tooth of the signal tooth 9 is limited, so as to complete the angle installation of the signal tooth 9 in the sink.
[0043] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacements or changes to the technical scheme and the inventive concept of the present application within the technical scope disclosed by the present application, and all of them should be covered within the protection scope of the present application.
