[0035] Some embodiments of the present application will be described in detail with reference to the drawings. In the case of no conflict, the following examples and features in the examples can be combined with each other.

[0036] The positioning device provided by the embodiment of the present application is suitable for installation of parts in a narrow space, and is also suitable for installation of small parts which are inconvenient to take, has high positioning precision, high installation efficiency, is convenient to operate, and is widely applicable.

[0037] In combination Figures 1 to 3 The positioning device 100 provided by the embodiment of the present application comprises a positioning part 110, a guide part 130 and a push rod 150. The positioning part 110 comprises a first clamping body 111 and a second clamping body 112. The first clamping body 111 and the second clamping body 112 are movably connected, so that the first clamping body 111 and the second clamping body 112 can move away from or close to each other. A containing groove 113 is formed between the first clamping body 111 and the second clamping body 112. The containing groove 113 can be used for movement of a to-be-installed part 101 therein. The guide part 130 is connected with the first clamping body 111 and / or the second clamping body 112. The guide part 130 is provided with an installation through hole 133. The installation through hole 133 is in communication with the containing groove 113. The push rod 150 is movably arranged in the installation through hole 133 and can extend into the containing groove 113. The push rod 150 is used for abutting against the to-be-installed part 101 in the containing groove 113, so that the to-be-installed part 101 moves out from one end of the containing groove 113 away from the push rod 150. The positioning device 100 is suitable for positioning of parts in a narrow installation space, has high positioning precision, and is convenient to operate.

[0038] It can be understood that the to-be-installed part 101 is placed in the containing groove 113 of the positioning part 110. The positioning part 110 and the guide part 130 are placed at a target installation position, such as a narrow operation space of some deep hole. Then the push rod 150 is inserted into the installation through hole 133, and the to-be-installed part 101 is pushed out from the containing groove 113, so that the to-be-installed part 101 is placed at the target installation position, the positioning precision of the to-be-installed part 101 is improved, and the operation is convenient. This is beneficial to improve the operation efficiency and the installation quality, can effectively avoid connection failure or part damage caused by uneven force of the to-be-installed part 101 due to low installation precision after installation of the to-be-installed part 101 is inclined, improves the connection reliability, and prolongs the service life of the to-be-installed part 101.

[0039] Optionally, one of the first clamping body 111 and the second clamping body 112 is provided with a fixing hole 122, and the other is provided with a fixing shaft 121, the fixing shaft 121 is inserted into the fixing hole 122 to realize the connection of the first clamping body 111 and the second clamping body 112. The first clamping body 111 and the second clamping body 112 can move relative to each other along the axial direction of the fixing shaft 121, so as to move away from each other or move close to each other. It can be understood that when the first clamping body 111 and the second clamping body 112 move close to each other, the space of the accommodating groove 113 becomes smaller, mainly the cross-sectional area of the accommodating groove 113 decreases, so that the to-be-installed part 101 is stored in the accommodating groove 113 and will not fall out of the accommodating groove 113. If the first clamping body 111 and the second clamping body 112 move away from each other, the space of the accommodating groove 113 becomes larger, mainly the cross-sectional area of the accommodating groove 113 increases, so that the to-be-installed part 101 falls out of the accommodating groove 113 to the outside of the accommodating groove 113, so as to fall into the target installation position, realizing the positioning of the to-be-installed part 101.

[0040] The positioning part 110 further comprises an elastic member 123, one end of the elastic member 123 is connected with the first clamping body 111, and the other end is connected with the second clamping body 112. Optionally, the accommodating groove 113 comprises an inlet end 116 and an outlet end 117 for moving the to-be-installed part 101, and the cross section of the accommodating groove 113 gradually decreases along the direction from the inlet end 116 to the outlet end 117. In other words, the cross section of the accommodating groove 113 gradually changes, the closer to the outlet end 117 of the accommodating groove 113, the smaller the cross section. As shown from the perspective, the cross section of the accommodating groove 113 decreases from top to bottom. In this embodiment, in the connected state of the first clamping body 111 and the second clamping body 112, the whole is roughly in the shape of a circular truncated cone, the upper end face is larger, and the lower end face is smaller. Figure 1

[0041] In combination with Figure 4 , it should be noted that the to-be-installed part 101 is first stored in the accommodating groove 113, and when the to-be-installed part 101 needs to be installed to the target position, the push rod 150 is used to extend into the accommodating groove 113 to apply a pushing force to the to-be-installed part 101, so as to push the to-be-installed part 101 out of the accommodating groove 113. During the process of applying the pushing force by the push rod 150, the outlet end 117 of the accommodating groove 113 is opened to push the to-be-installed part 101 out of the outlet end 117. After the to-be-installed part 101 is pushed out, the pushing force of the push rod 150 is removed, at this time the first clamping body 111 and the second clamping body 112 move close to each other under the restoring force of the elastic member 123, and return to the initial state. It should be understood that in the initial state, the cross section of the outlet end 117 of the accommodating groove 113 is small, and the to-be-installed part 101 will not fall out of the outlet end 117 without external pushing force.
