[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment: Please refer to Figures 1 to 6 , and according to the embodiment of the present utility model, a technical solution is provided: A positioning device for a profiled part of a bullet train that is convenient to disassemble, including the body 21 of the profiled part, and further including a housing 1; a positioning block 2, which is movable along the height direction of the housing 1, and a positioning hole 3 adapted for the body 21 of the profiled part to be movably inserted is provided at the top of the positioning block 2; a guiding member 4, which is arranged on the housing 1 and is used to guide the positioning block 2 to move along its height direction and elastically support the positioning block 2; and a locking mechanism 5, which can selectively relatively fix the body 21 of the profiled part inserted into the positioning hole 3 and the positioning block 2 to restrict or allow the body 21 of the profiled part to move relative to the positioning block 2.

[0027] For the positioning device for the press-shaped parts of the EMU that is conveniently disassembled and adopts the above structure, when a user needs to position the press-shaped part body 21, first, align the bottom of the press-shaped part body 21 with the positioning hole 3 of the positioning block 2 and insert its bottom into the positioning hole 3. When the bottom of the press-shaped part body 21 is completely inserted into the positioning hole 3, the user fixes the press-shaped part body 21 relative to the positioning block 2 through the locking mechanism 5 to limit unnecessary movement or shaking of the press-shaped part body 21 during subsequent use. After the press-forming operation of the press-shaped part body 21 is completed, the guiding member 4 guides the positioning block 2 to move upward along its height direction until the positioning block 2 disengages from the inside of the housing 1. At this time, the user releases the fixation of the press-shaped part body 21 through the locking mechanism 5, and then the user can easily take out the press-shaped part body 21 from the positioning hole 3. The entire disassembly process is simple and efficient.

[0028] In this embodiment, the guiding member 4 includes four guiding rods 6, a first spring 7, and two bearing parts 8. Each pair of guiding rods 6 is relatively spaced on opposite sides inside the housing 1. The two bearing parts 8 and the first spring 7 are both sleeved on the guiding rods 6. The two ends of the first spring 7 elastically abut against the two bearing parts 8 respectively. All four guiding rods 6 movably penetrate through the positioning block 2. When the press-forming operation of the press-shaped part body 21 by the user is completed, the first spring 7 on the guiding rods 6 elastically abuts against the bearing part 8 to drive the positioning block 2 to move upward until the positioning block 2 disengages from the inside of the housing 1, so as to facilitate the user to take out the press-shaped part body 21.

[0029] In this embodiment, the locking mechanism 5 includes a locking rod 9, a first limiting part 10, an abutting part 11, and a second spring 12. An activity cavity 13 is defined inside the positioning block 2. The activity cavity 13 communicates with the positioning hole 3. The locking rod 9 is movably arranged inside the positioning hole 3. The abutting part 11 is arranged at the first end of the locking rod 9. The first limiting part 10 is sleeved on the locking rod 9. The second spring 12 is sleeved on the locking rod 9 and arranged inside the activity cavity 13. The second spring 12 elastically abuts against the first limiting part 10. When the user needs to fix the press-shaped part body 21 relative to the positioning block 2, first, insert the bottom of the press-shaped part body 21 into the positioning hole 3. Before that, the user pulls the locking rod 9 to retract the abutting part 11 into the activity cavity 13 so that the bottom of the press-shaped part body 21 can be inserted into the positioning hole 3. When the bottom of the press-shaped part body 21 is completely inserted into the positioning hole 3, release the locking rod 9. At this time, with the release of the locking rod 9, the second spring 12 will utilize its accumulated elastic potential energy to push the first limiting part 10 and the locking rod 9 to move towards the positioning hole 3. During this process, the abutting part 11 will also move forward until it contacts the side surface of the press-shaped part body 21 that has been inserted into the positioning hole 3. After the abutting part 11 contacts the press-shaped part body 21, the elastic force of the second spring 12 will continue to act, so that the abutting part 11 exerts a stable clamping force on the press-shaped part body 21.

[0030] In this embodiment, a second limiting portion 14 is provided at the second end of the locking rod 9 to limit the locking rod 9 from completely entering the movable cavity 13. When the user releases the locking rod 9 and it is abutted by the second spring 12 into the movable cavity 13, the second limiting portion 14 will limit the locking rod 9 from completely retracting deep into the movable cavity 13, so as to prevent the user from having difficulty in pulling the locking rod 9 after it enters the movable cavity 13.

[0031] In this embodiment, an abutting groove 15 is formed at the top of the positioning block 2. An abutting rod 16 is movably arranged in the abutting groove 15. The abutting rod 16 movably penetrates through the positioning block 2. A supporting portion 17 is provided at the top of the abutting rod 16. An activity groove 18 communicating the abutting groove 15 with the peripheral side wall of the positioning block 2 is formed in the positioning block 2 along its height direction. An activity rod 19 is provided on the abutting rod 16. The free end of the activity rod 19 is movably arranged in the activity groove 18. When the user needs to take out the pressing member body 21 from the positioning hole 3, first, move the activity rod 19 along the top of the activity groove 18 to drive the abutting rod 16 to move upward until the top of the abutting rod 16 contacts the pressing member body 21. At this time, the user continues to move the activity rod 19 upward to drive the abutting rod 16 to move, so that the pressing member body 21 gradually disengages from the positioning hole 3, facilitating the user to take out the pressing member body 21.

[0032] In this embodiment, a lifting rod 20 is vertically provided at the free end of the activity rod 19. The lifting rod 20 will give the user a fulcrum for lifting the activity rod 19, facilitating the user to lift the activity rod 19.

[0033] Working principle: When the user needs to position the profile body 21, first, align the bottom of the profile body 21 with the positioning hole 3 of the positioning block 2, and insert the bottom of the profile body 21 into the positioning hole 3. When the bottom of the profile body 21 is fully inserted into the positioning hole 3, the user pulls the locking rod 9 to retract the abutment portion 11 into the active cavity 13 so that the bottom of the profile body 21 is inserted into the positioning hole 3. When the bottom of the profile body 21 is fully inserted into the positioning hole 3, the locking rod 9 is released. At this time, as the locking rod 9 is released, the spring 12 will use its accumulated elastic potential energy , pushing the limiting part 10 and the locking rod 9 to move in the direction of the positioning hole 3. During this process, the abutting part 11 will also move forward until it contacts the side of the profiling body 21 that has been inserted into the positioning hole 3. After the abutting part 11 contacts the profiling body 21, the elastic force of the spring 2 12 will continue to act, so that the abutting part 11 applies a stable clamping force to the profiling body 21 to limit the unnecessary movement or shaking of the profiling body 21 during subsequent use. After the profiling operation of the profiling body 21 is completed, the spring 1 7 located on the guide rod 6 will rebound. The locking mechanism 5 is actuated to abut against the bearing portion 8 to drive the positioning block 2 to move upward until the positioning block 2 is separated from the interior of the housing 1, so that the user can take out the profile body 21. At this time, the user can release the fixation of the profile body 21 by reverse operation of the locking mechanism 5, and then the user can easily take out the profile body 21 from the positioning hole 3. The whole disassembly process is simple and efficient. When the user releases the locking rod 9 so that it is abutted against the active cavity 13 by the spring 12, the limiting portion 14 will limit the locking rod 9 to completely retreat to the depth of the active cavity 13 to prevent the locking rod 9 from entering the active cavity 13. It is difficult for the user to pull the locking rod 9 later; when the user needs to take the stamping body 21 out of the positioning hole 3, first, the movable rod 19 is moved along the top of the movable groove 18 to drive the abutment rod 16 to move upward until the top of the abutment rod 16 contacts the stamping body 21. At this time, the user continues to move the movable rod 19 upward to drive the abutment rod 16 to move, so that the stamping body 21 gradually disengages from the positioning hole 3, so that the user can take out the stamping body 21; the lifting rod 20 will give the user a fulcrum for lifting the movable rod 19, so that the user can lift the movable rod 19.
