[0001] The invention relates to the field of electric passenger car door processing, and in particular to a production device for rail transit electric passenger car doors. Background Art

[0002] The doors of rail transit electric passenger cars are an important part of the cars. They are not only the passage for passengers and drivers to get on and off the train, but also the key facilities to ensure the safe and stable operation of the train, improve the service quality and the passengers' riding experience.

[0003] For high-speed urban rail transit electric passenger cars, the design of their doors is relatively important. In order to improve their airtightness during high-speed driving and facilitate opening and closing of the doors, the door structure is usually not a square structure, but a polygonal structure at the top. The two corners at the top are usually inclined and set at a certain inclination angle to facilitate the opening and closing of the doors, and the corners are obtuse structures to facilitate the setting of sealing rings at the corners for sealing.

[0004] In the existing door processing process, it is necessary to install a sealing ring and apply glue. Usually, the door is placed on a frame platform and then glue is applied along the door. Since the door is not a regular square, one end of the door placed on the frame platform will be raised, which makes it difficult to operate during the gluing and installation of the sealing ring. Summary of the invention

[0005] The present invention aims at the deficiencies in the prior art, and by arranging a pressure block for pressing the door on the platform, it is convenient to install the sealing ring and glue.

[0030] See also Figure 1 - Figure 7 A rail transit electric passenger car door production device includes a processing table 1 and a fixing assembly 2. The processing table 1 includes a support frame 11 and a table plate 12 supporting a door 3. A protrusion 121 is provided on the table plate 12. The protrusion 121 is smaller than the door 3. The protrusion 121 raises the door 3.

[0031] The fixing assembly 2 includes a pressure block 21 arranged on the upper side of the vehicle door 3 and a driving component 22 arranged on the lower side of the platform 12. The driving component 22 is a cylinder. The pressure block 21 is arranged on the side of the vehicle door 3 where no glue is applied, which is convenient for gluing and installing a sealing ring. A lifting rod 23 is arranged on the side of the platform 12. The driving component 22 is connected to the pressure block 21 through the lifting rod 23. The pressure block 21 corresponds to the horizontal section of the vehicle door 3. The horizontal section is longer, which is convenient for fixing the vehicle door 3 on the processing table 1. An inclined plate 24 supporting the upturned end of the vehicle door 3 is arranged on the platform 12. The inclined plate 24 supports the upturned section of the vehicle door 3, making the vehicle door 3 more stable. Rubber pads 25 are arranged on the inclined plate 24 and the raised portion 121. The rubber pads 25 are used for buffering to prevent the vehicle door 3 from being scratched.

[0032] The lifting rod 23 is connected to the pressure block 21 through an elastic member 26. The pressure block 21 is made of rubber to prevent the vehicle door 3 from being deformed by pressure. The elastic member 26 includes a transverse plate 261. A connecting rod 262 is longitudinally slid on the transverse plate 261. The lower end of the connecting rod 262 is fixed to the pressure block 21. The upper end of the connecting rod 262 passes through the transverse plate 261 and is connected to the limiting block 263. A spring 264 is sleeved on the connecting rod 262. The two ends of the spring 264 are respectively connected to the pressure block 21 and the transverse plate 261. One end of the transverse plate 261 is fixedly connected to the top of the lifting rod 23.

[0033] The lower side of the horizontal plate 261 is connected to a limiting plate 4, and the limiting plate 4 is located on the side where no glue is applied.

[0034] A plurality of round rods 27 that can be raised and lowered are arranged on the lower side of the platform 12, the top ends of the round rods 27 are connected to rollers 28, the lower ends of the round rods 27 are connected to lifting frames 29, the top ends of the driving components 22 are fixed to the lifting frames 29, the arrangement of the rollers 28 facilitates the placement and removal of the vehicle door 3, and the platform 12 and the rubber pad 25 are both provided with through grooves for the lifting of the round rods 27. Since the vehicle door 3 has an upward section, the rollers 28 corresponding to the upward section are higher than the rollers 28 corresponding to the horizontal section.

[0035] One side of the lifting frame 29 is connected to a limit plate 2 5, which is vertically arranged with the limit plate 1 4. The upper end of the limit plate 2 5 is not higher than the vehicle door 3 and is in contact with the vehicle door 3. The limit plate 1 4 and the limit plate 2 5 cooperate to place the vehicle door 3 in an orderly manner, which is convenient for the subsequent installation of the sealing ring and gluing.

[0036] When the door 3 needs to be removed, the driving component 22 causes the lifting frame 29 to rise, and the lifting frame 29 raises the lifting rod 23, and the lifting rod 23 raises the pressing block 21 through the elastic member 26, so that the pressing block 21 releases the pressing of the door 3. At the same time, the lifting frame 29 raises the round rod 27, and the round rod 27 raises the roller 28. Due to the gap between the roller 28 and the door 3, the roller 28 contacts the door 3 only after the pressing block 21 is separated from the door 3, thereby lifting the door 3. At this time, the door 3 is supported by multiple rollers 28, which is convenient for removing the door 3. When placing the car door 3, the car door 3 is placed on the roller 28, and one side of the car door 3 corresponds to the limit plate 25, and then the car door 3 is pushed so that the car door 3 stops when it contacts the limit plate 14, and the contact starts the driving component 22 to make the lifting frame 29 descend, and the lifting frame 29 descends with the round rod 27 and the lifting rod 23 at the same time. When the roller 28 is lower than the rubber pad 25, the car door 3 falls on the rubber pad 25 and is supported. As it continues to descend, the pressing block 21 contacts the car door 3, and finally the pressing block 21 presses the car door 3 tightly under the compression state of the spring 264 to fix the car door 3.

[0037] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
