Description

Technical Field

[0001] The utility model relates to the technical field related to subway vehicle production and processing, in particular to a deburring device for processing the bottom end frame of a subway vehicle. Background Art

[0002] After the stamping of the subway car bottom frame plate is completed, a large number of burrs will appear on the stamped edges due to the stretching of the plate. To ensure the stability of subsequent welding and electroplating operations, existing production workshops mostly use electrolysis to remove these burrs. Compared with existing manual and mechanical removal methods, this method can clean the slots in the middle of the plate.

[0003] However, the electrolytic cleaning operation still uses a more traditional lifting structure to place the plates in the electrolytic cell. This method requires the plates to be pulled to a high place first, which obviously poses a great safety hazard. For this reason, we proposed a deburring device for processing the bottom frame of subway vehicles. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-6 The utility model provides a technical solution: a deburring device for processing the bottom end frame of a subway vehicle, comprising an electrolytic cell 1, a supporting frame 2 is provided in the electrolytic cell 1, the outer periphery of the supporting frame 2 is in contact with the inner wall of the electrolytic cell 1, a plurality of threaded sleeves 21 are fixedly installed on the lower end of the supporting frame 2, and a plurality of limiting rotating seats 23 corresponding to the positions of the threaded sleeves 21 are fixedly installed on the upper side of the bottom end of the inner cavity of the electrolytic cell 1

[0027] Working principle: When the bottom frame of the subway vehicle is immersed in the electrolyte inside the electrolytic cell 1, the bottom frame plate is placed on the upper end of the support frame 2, and then at the lower end of the electrolytic cell 1, the permanent magnet rotating shaft 25 is rotated. The second magnet 251 on its periphery is magnetically connected with the first magnet 241 on the inner wall of the permanent magnet rotating sleeve 24, which can drive the threaded rod 22 to rotate on the upper end of the limit rotating seat 23. Since the periphery of the support frame 2 is in contact with the inner wall of the electrolytic cell 1, the movement direction of the support frame 2 can be restricted, so that the rotating threaded rod 22 can drive the support frame 2 to move downward through the threaded connection between it and the threaded sleeve 21, so that the bottom frame plate is immersed in the electrolyte inside the electrolytic cell 1;

[0028] On the contrary, the reverse rotation of the permanent magnet rotating shaft 25 can drive the support frame 2 and the upper and lower end frame panels of the support frame 2 to be lifted to the upper side of the electrolytic cell 1, so as to facilitate the recovery of the subway vehicle bottom frame.

[0029] As a further description of the above technical solution: a driven wheel 26 is fixedly installed at the lower end of each permanent magnet rotating shaft 25, and the driven wheel 26 is arranged on the lower side of the electrolytic cell 1, and a motor 27 is fixedly installed at the lower end of the electrolytic cell 1 through a connecting plate, and a driving wheel 28 is fixedly installed at the outer end of the motor 27 through its output shaft, and a transmission belt 29 is provided on the outer periphery of the driving wheel 28 and multiple driven wheels 26.

[0030] Specifically, when it is necessary to rotate each permanent magnet rotating shaft 25 at the same time, the motor 27 is started, and the driving wheel 28 can be driven to rotate through its output shaft. Then, a transmission belt 29 is provided on the outer periphery of the driving wheel 28 and multiple driven wheels 26, which can drive each driven wheel 26 to rotate with it, thereby achieving the effect of driving each permanent magnet rotating shaft 25 to rotate at the same time.

[0031] As a further description of the above technical solution: a water pump 3 is fixedly installed at the lower end of the electrolytic cell 1, and a water inlet pipe 31 is fixedly connected to the water inlet and a water outlet pipe 32 is fixedly connected to the water outlet on the periphery of the water pump 3. The water inlet pipe 31 is arranged in sections, and the water inlet pipe 31 includes a first tube body 311 and a second tube body 312. A filter tube 33 is provided between the first tube body 311 and the second tube body 312, and a filter screen 34 is provided in the filter tube 33. A positioning clamp 341 fixedly connected to the inner wall of the filter tube 33 and a movable clamp 342 connected to the inner wall of the filter tube 33 are provided. The filter screen 34 is provided between the positioning clamp 341 and the movable clamp Between 342, threaded rings 36 are provided on both sides of the periphery of the filter tube 33 and are threadedly connected thereto, and the threaded rings 36 on both sides are respectively plugged into the peripheries of the first tube body 311 and the second tube body 312, and positioning grooves 35 are provided on the upper sides of the facing end surfaces of the first tube body 311 and the second tube body 312. Positioning blocks 351 are fixedly installed on both sides of the periphery of the filter tube 33 and are respectively engaged with the positioning grooves 35 on both sides. A rotating ring 37 is rotatably installed in the middle part of the periphery of the filter tube 33, and limiting holes 381 are provided on the facing end surfaces of the two threaded rings 36. Limiting rods 38 are fixedly installed on both sides of the rotating ring 37 and are respectively plugged into the limiting holes 381 on both sides.

[0032] Specifically, when installing the filter tube 33, multiple filter screens 34 and a movable snap ring 342 are installed into the filter tube 33. The filter screens 34 can be positioned by the movable snap rings 342 and the positioning snap rings 341 on both sides of the filter screens 34.

[0033] The filter tube 33 can be installed between the first tube body 311 and the second tube body 312 by the engagement effect between the positioning block 351 and the positioning slot 35. Then, the rotating ring 37 is rotated on the periphery of the filter tube 33. The limiting plug rod 38 is plugged into the limiting plug hole 381, so that the rotating rotating ring 37 can drive the threaded rings 36 on both sides of the periphery of the filter tube 33 to rotate with it. The rotating threaded ring 36, through the threaded connection between its inner wall and the periphery of the filter tube 33, can expand outward to respectively plug into the periphery of the first tube body 311 and the second tube body 312, thereby completing the installation of the filter tube 33.

[0034] During the storage and transportation of the bottom rack panels, dust and other impurities will adhere to their surface, which will cause the dust and other impurities on the surface to fall into the electrolyte during the electrolytic deburring process. When it is necessary to collect the impurities in the electrolyte, the water pump 3 is started, and the electrolyte inside the electrolytic cell 1 can be circulated through the water inlet pipe 31 and the water outlet pipe 32. When the electrolyte passes through the filter 34, the impurities in the electrolyte can be blocked by the filter 34, and the blocked impurities can be recovered through the filter tube 33.
