[0030] The utility model is further described in detail below in combination with the drawings and specific embodiments.

[0031] The utility model provides a kind of assembly positioning device, including main body structure 2, the top of main body structure 2 is provided with positioning head 1, bottom is provided with positioning mark device, positioning head 1 is detachably fixed connection with main body structure 2 at set angle, when positioning, positioning head 1 is connected with first positioning structure assembly, positioning mark device is towards second positioning structure, and mark positioning point on second positioning structure.

[0032] In the embodiment, the specific structure of the assembly positioning device provided by the utility model and the use method in the positioning process are introduced, taking the rail vehicle including the urban rail vehicle as an example, further, the specific structure and use method of the assembly positioning device provided by the utility model are introduced, taking the positioning of the two ends of the handrail in the handrail assembly process of the urban rail vehicle as an example.

[0033] After the completion of the urban rail vehicle in car floor laying, handrail is installed again, handrail mounting hole is set on roof, handrail top is inserted into mounting hole and is assembled and connected with roof, and bottom mounting hole is positioned on floor directly below roof mounting hole, so that the bottom of handrail is assembled with bottom mounting hole, and the handrail rod is perpendicular to floor. Alternatively, the top of handrail is assembled and connected with horizontal tie rod in vehicle, and the bottom is assembled and connected perpendicularly with floor, wherein the roof or horizontal tie rod is first positioning structure, and floor is second positioning structure.

[0034] As Figures 1 to 4As shown, the assembly positioning device comprises a main body structure 2, which is a hollow rod structure in this embodiment, and the main body structure 2 at least comprises a telescopic rod 21 to adjust the length of the whole device, which is suitable for different vehicle models, different heights and different installation positions, thereby improving the application range of the assembly positioning device. During use, the telescopic length of the telescopic rod 21 is adjusted according to the length (height) of the to-be-assembled handrail.

[0035] At the top of the main body structure 2, a positioning head 1 is arranged in detachable fixed connection with the top of the main body structure 2. According to the included angle between the roof and the floor, the included angle between the positioning head 1 and the main body structure 2 is determined, and the included angle between the positioning head 1 and the main body structure 2 is fixed by a limiting structure, so that the included angle is unchanged during positioning.

[0036] For example, when the roof has an inclination angle, that is, the virtual extension line of the roof intersects with the floor, according to the intersection angle, the included angle between the positioning head 1 and the main body structure 2 is determined to be complementary to the angle, so that after the positioning head 1 is inserted into the mounting hole of the roof, the main body structure 2 can be perpendicular to the floor; when the roof and the transverse pull rod are parallel to the floor, the positioning head 1 and the main body structure 2 are assembled and fixed perpendicularly to each other.

[0037] The positioning head 1 and the main body structure 2 are detachably assembled and fixed, different sizes of the positioning head 1 can be replaced according to the diameter of the mounting hole and the handrail, so that the positioning head 1 is inserted and fixed with the mounting hole, and it can be ensured that the positioning head 1 will not fall out of the mounting hole during positioning.

[0038] Further, the shape of the positioning head 1 matches the shape of the mounting hole, the positioning head 1 is a hard rubber column, or at least a hard rubber column is arranged at the top of the positioning head 1, so that the positioning head 1 is in soft contact with the mounting hole. Preferably, the diameter of the rubber column part of the positioning head 1 is slightly larger than the diameter of the mounting hole, so that the positioning head 1 is in interference fit with the mounting hole, without the need for screw fixation, and the positioning head 1 will not fall out of the mounting hole during positioning, and the soft contact will not cause damage to the mounting hole. Alternatively, the positioning head can also use other structures that can be assembled and connected with the mounting hole, without any requirements and limitations, as long as assembly and fixation can be achieved.

[0039] A plurality of positioning protrusions are arranged at the top of the positioning head 1, the positioning protrusions protrude from the top surface of the positioning head, and the positioning protrusions correspond to the positions of the bolt holes in the mounting hole, so that after the positioning head 1 is inserted into the mounting hole, the positioning protrusions are inserted into the bolt holes, further limiting the relative position of the positioning head 1 in the mounting hole.

[0040] Preferably, screw holes are arranged on the positioning head 1 (hard rubber column) corresponding to the positions of the bolt holes in the mounting hole, and after the bolt 11 passes through the corresponding screw holes of the roof panel and the positioning head, the positioning head 1 is bolted with the mounting hole.

[0041] Further, the positioning head 1 is connected perpendicularly to the main body structure 2, reducing the adjustment process, and a level is arranged on the positioning head 1, after the positioning head 1 is inserted into the mounting hole, the level is exposed outside the mounting hole, the position of the positioning head 1 can be adjusted by observing the state of the level, so that the main body structure 2 is perpendicular to the floor.

[0042] Further, the positioning head 1 is connected to the main body structure 2 through a ball hinge or the like, so that after the positioning head 1 is assembled with the mounting hole on the top plate in an interference fit, the main body structure 2 forms a structure similar to a plumb line under the action of gravity, vertically downward, so that the main body structure 2 is directly and naturally perpendicular to the floor.

[0043] A positioning marking device is arranged at the bottom of the main body structure 2 to mark the positioning point on the second fixed structure, i.e. the floor.

[0044] In the embodiment, the positioning marking device includes a marking pen (not shown in the figure), which is arranged at the bottom of the main body structure 2, and after the positioning head 1 is assembled and fixed with the top plate or the transverse pull rod in an interference fit, the marking pen faces the floor, and the overall length of the main body structure 2 is adjusted by pulling the telescopic rod 21, so that the marking pen marks the positioning point on the floor.

[0045] The marking pen can be directly assembled and connected with the main body structure 2, as shown in Figure 1 The marking pen is clamped by the clamp 3, which is convenient for replacing the marking pen. The marking pen is a general term, which can be any structure, for example, a marker in conventional technology, or other structures that can mark the positioning point on the floor, such as a screw with a sharp tip.

[0046] Further, the marking pen can also be integrated with the main body structure 2, for example, a shallow groove is arranged at the bottom of the main body structure 2, and the positioning marking device includes an ink cartridge, when used, the bottom of the main body structure 2 presses the ink powder (oil) in the ink cartridge, so that the bottom of the main body structure 2 dips the ink powder, the telescopic rod 21 is pulled, and the bottom of the main body structure 2 directly contacts the floor cloth, so that the ink powder is stained on the floor cloth, forming the positioning point. Or the telescopic rod 21 is a lead screw, and a sharp end is arranged at the bottom of the main body structure 2, when the lead screw is rotated, the sharp end rotates on the floor cloth, forming a positioning hole. The specific structure and form of the marking pen are not limited, which can form a clear and visible mark and positioning point on the floor cloth.

[0047] Further, the marking pen and the main body structure 2 can adopt a soft connection, so that the marking pen itself can form a structure similar to a plumb line, improving the positioning accuracy.

[0048] Further, the positioning marking device comprises a plumb line which is connected to the main body structure 2 in a flexible manner, and a marking pen is arranged at the bottom of the plumb line, the weight of the main body structure 2 is increased through the plumb line, and the vertical guiding effect is improved. The marking pen and the plumb line can be connected through a clamp, the marking pen is clamped through the clamp, or the marking pen and the plumb line are integrated.

[0049] In the embodiment, the flexible connection mentioned above refers to that the plumb line or the marking pen is vertically downward under the action of gravity through a flexible line which can be any form of thread-like article. Preferably, the flexible line can be a telescopic line, so that the plumb line or the marking pen can be pulled while being vertically downward, and positioning marking can be performed.

[0050] In use, according to the size of the mounting hole on the roof or the transverse pull rod, a proper positioning head 1 is selected, so that the positioning head 1 can be in interference fit with the mounting hole, and the interference force is appropriate, so that the positioning head 1 cannot fall off from the mounting hole under the action of gravity of the main body structure 2, and the positioning head 1 cannot be removed from the mounting hole after positioning, or a large force is not needed to remove the positioning head 1, and the positioning head 1 will not be damaged in the removal process.

[0051] After the positioning head 1 is inserted into the mounting hole on the roof or the transverse pull rod, if the main body structure 2 and the positioning head 1 are assembled and connected in a ball hinge or a structure similar to the ball hinge, the main body structure 2 drives the marking pen to be vertically downward and directly perpendicular to the floor, the telescopic rod 21 is adjusted, so that the overall length of the main body structure 2 is adjusted, and the marking pen marks the positioning point on the floor cloth in the vertically downward state; if the main body structure 2 and the positioning head 1 are connected at a predetermined angle, after the positioning head 1 is inserted into the mounting hole, the end of the main body structure 2 is perpendicular to the floor through the connection angle and / or by adjusting the connection angle, so that the marking pen leaves the positioning mark on the floor cloth by adjusting the telescopic rod 21.

[0052] After the positioning mark is left on the floor cloth, the telescopic rod 21 is adjusted in the reverse direction, the length of the main body structure 2 is shortened, and the positioning head 1 is removed from the mounting hole, and the main body structure 2 is stored in the shortest state. According to the marking point left on the floor cloth, the bottom mounting hole is processed, and the assembly and fixation of the handrail are performed.
