Description

Technical Field

[0001] The invention relates to the technical field of fuel cell production and processing, and in particular to an inner and outer surface burr grinding device for fuel cell processing. Background Art

[0002] With the development of new energy vehicles, fuel cells are widely used. In order to ensure the accuracy of fuel cell reaction materials installed in the fuel cell box during the production of automotive fuel cells, the inner and outer surfaces of the fuel cell box need to be smoothed. Grinding and polishing are currently the main processing methods. However, because there will be an angle when grinding the inside and outside of the fuel cell box, ordinary grinding equipment will have a dead angle when grinding the angle, resulting in insufficient grinding. At this time, it is necessary to manually grind the dead angle with a file or angle grinding equipment.

[0003] The existing grinding equipment has poor adjustment performance for fuel cell boxes of different sizes due to the differences in sizes of different batches of fuel cell boxes during angle grinding. The existing grinding equipment needs to switch angles multiple times to complete the angle grinding of the fuel cell box, which increases the number of grinding steps in the production process, increases equipment and labor costs, and reduces production efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a burr grinding device for inner and outer surfaces of fuel cells for processing, so as to solve the problems of poor adjustability and synchronous grinding angle of existing grinding devices.

[0041] By setting the adjustment component 13, the angle between the grinding ends needs to be adjusted according to the different sizes of the fuel cell box before grinding, so as to avoid the grinding position being misaligned. By setting the grinding component 14, when grinding the inner and outer corners of the fuel cell box of different sizes before grinding, the angles of the grinding positions of different sizes change, and it is necessary to adjust the angle between the No. 1 grinding block 145 and the No. 2 grinding block 148 so that the grinding position is always in contact with the inner and outer corner surfaces of the fuel cell box.

A first mounting ring 9 is connected to the bottom of the push rod 8, and the first mounting ring 9 is sleeved on the upper half of the outer side of the slide tube 7. A limiting ring 10 is arranged on the outer side of the middle section of the slide tube 7. A second mounting ring 11 is arranged on the outer fixed sleeve of the lower half of the slide tube 7. A sliding groove is designed at the outer ends of the first mounting ring 9 and the second mounting ring 11. The sliding grooves of the first mounting ring 9 and the second mounting ring 11 are designed in a "T" shape. A mounting strip 12 is connected to the center of the second mounting ring 11. The inner end of the mounting strip 12 is designed as a "T" head. A sliding groove is designed in the mounting strip 12. The sliding groove of the mounting strip 12 is designed in a "T" shape. There are four mounting strips 12, and the mounting strips 12 are arranged opposite to each other in pairs.

[0043] The adjustment component 13 is arranged between the mounting strips 12. The adjustment component 13 includes a No. 2 threaded rod 131. The front and rear ends of the No. 2 threaded rod 131 are threadedly connected with mounting blocks 132.

The grinding assembly 14 includes a connector 141, which is fitted and slidably installed in the outer slide groove of the first mounting ring 9. The top of the outer end of the connector 141 is rotatably connected to a moving rod 142, and the lower end of the moving rod 142 is slidably connected to a No. 2 slider 143, and the No. 2 slider 143 fits and slides in the top slide groove of the mounting strip 12. The outer end of the No. 2 slider 143 is connected to a slide 144, and a No. 1 grinding block 145 is fixed below the outer top boss of the slide 144.

The grinding assembly 14 grinds the inner and outer corners of battery boxes of different specifications.

[0047] In this embodiment, before grinding, the operator needs to start the No. 2 electric push rod 8 to push the first mounting ring 9 downward, so that the first mounting ring 9 slides downward on the sliding tube 7. The sliding first mounting ring 9 will drive the connecting head 141 and the moving rod 142 to move downward. The moving moving rod 142 will squeeze the No. 2 slider 143 on the mounting bar 12 to slide outward. The sliding No. 2 slider 143 drives the slide 144 and the No. 1 grinding block 145 to move together to fit the inner corner position of the fuel cell box, and then close the No. 2 electric push rod 8. At this time, the operator rotates the adjustment After the section rod 146 aligns the No. 2 slide bar 147 and the No. 2 grinding block 148 with the outer corner of the fuel cell box, the No. 2 slide bar 147 is pushed inward to make the No. 2 grinding block 148 fit with the outer corner of the fuel cell box, and the first bolt 149 is tightened to contact the No. 2 slide bar 147 to fix it, and then the second bolt 1410 and the nut 1411 are tightened. At this time, the position of the grinding block for the inner and outer corners of this type of fuel cell box size is adjusted, so that when grinding the inner and outer corners of fuel cell boxes of different sizes, the grinding head can be adjusted according to different sizes.

[0048] The working principle provided by the present invention is that when in use, the operator manually rotates the crank 136 to drive the second threaded rod 131 to rotate, and the front and rear mounting blocks 132 on the second threaded rod 131 move relatively, and the relatively moving mounting blocks 132 drive the support rod 133 and the first slider 134 to move inward, and the moving first slider 134 is squeezed and slides in the first slider 135. At the same time, the first slider 134 resists the first slider 135 and the mounting bar 12, so that the mounting bar 12 rotates and slides in the second mounting ring 11, so that the angle between the two opposing mounting bars 12 becomes smaller, and conversely, when the crank 136 is rotated in the opposite direction to drive the second threaded rod 131 to rotate, the angle between the two opposing mounting bars 12 becomes larger, thereby adjusting the diagonal position of the grinding assembly 14, so that the grinding assembly 14 can be consistent with the diagonal position of fuel cell boxes of different sizes, and then the operator starts the second electric push rod 8 to push the first mounting ring 9 downward, so that the first mounting ring 9 slides The first mounting ring 9 slides downward on the tube 7, and the moving rod 142 moves downward. The moving rod 142 squeezes the second slider 143 on the mounting bar 12 to slide outward. The sliding second slider 143 drives the slide 144 and the first grinding block 145 to move together to fit the inner corner position of the fuel cell box sample for comparison, and then closes the second electric push rod 8. At this time, the operator rotates the adjustment rod 146 to make the second slider 147 and the second grinding block 1 After the No. 48 is aligned with the outer corner of the fuel cell box, the No. 2 slide bar 147 is pushed inward to make the No. 2 grinding block 148 fit with the outer corner of the fuel cell box, and then the first bolt 149 is tightened to abut against the No. 2 slide bar 147 to fix it, and then the second bolt 1410 and the nut 1411 are tightened, and then the No. 1 threaded rod 21 on the threaded plate 2 is completely rotated to abut against the fuel cell box to limit it. For this type of fuel cell box size inner and outer corners, the positions of the No. 1 grinding block 145 and the No. 2 grinding block 148 are adjusted;

[0049] During grinding, the operator starts the No. 1 electric push rod 5 to move back and forth up and down. The moving No. 1 electric push rod 5 drives the fixed ring 6 and the sliding tube 7 to move up and down outside the sliding column 4. The moving sliding tube 7 drives the No. 2 electric push rod 8, the first mounting ring 9, the second mounting ring 11 and the mounting strip 12 to move up and down.
