Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to a deburring device with a waste chip cleaning structure. Background Art

[0002] Burrs are everywhere in the metal processing process. No matter how advanced the precision equipment is, they will be born with the product. The main types of burrs are edge burrs, sharp burrs, spatter, etc., which are protruding excess metal residues that do not meet the product design requirements. So far, there is no effective way to eliminate this problem in the production process. Therefore, in order to ensure the design requirements of the product, engineers can only work hard on the removal of burrs in the later stage.

[0003] In the prior art, the purpose of deburring is generally achieved by belt grinding, grinding, elastic grinding wheel grinding and polishing. For example, the Chinese utility model patent with publication number CN209407593U discloses a deburring device for gear processing. The utility model is provided with a wire disc. The wire disc rotates at high speed on the gear and rotates vertically with the gear to effectively remove the burrs on the gear without damaging the gear. However, it is not possible to grind and deburr the chamfered structure at the edge of the gear. In addition, this solution is very likely to cause waste chips to splash during the deburring process, which is troublesome to clean up later and is not conducive to the centralized cleaning of waste chips. Therefore, we propose a deburring device with a waste chip cleaning structure to solve the above problems. Utility Model Content

[0004] The main purpose of the utility model is to provide a deburring device with a waste chip cleaning structure, which can effectively solve the problems in the background technology.

[0007] Preferably, a slave pulley is rotatably installed on the front side of the middle position of the I-shaped fixing frame, and the slave pulley and the main rotating wheel are fixedly connected via a transmission shaft. The rotation of the slave pulley can drive the main rotating wheel to rotate, thereby realizing the rotation of the sanding belt.

[0008] Preferably, a gear positioning base is fixedly installed at the left position of the upper end of the I-shaped fixing frame, which is used to fix and drive the rotation of the gear.

[0012] 1. By adjusting the position of the adjustable fixing part on the I-shaped fixing frame and cooperating with the limiting effect of the tension spring, a height difference can be formed between the adjusting wheel and the main wheel, so that the abrasive belt is tilted at a certain angle, and then the edge chamfer position of the gear can be polished and deburred, thereby improving the deburring effect of the device.

Some tightly adhered waste chips will also fall off under the scraping of the scraper plate. Finally, the cleaning box can be directly pulled out of the collection box through the design of the pull-out groove, and the cleaned waste chips can be centrally processed. The structure is simple and the operation is convenient. The waste chips can be cleaned while the gear is deburred, which greatly reduces the time for cleaning the waste chips and improves the processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

A tension spring 10 is arranged between the lower ends, a positioning piece 11 is fixedly sleeved on the outer side of the rotating square rod 9 near the upper end, an adjusting wheel 12 is rotatably installed on the positioning piece 11 near the right end, a fixed rotating wheel 13 is rotatably installed on the lower end of the I-shaped fixing frame 2 between the adjustable fixing piece 8 and the rotating square rod 9, a sanding belt 14 is arranged between the main rotating wheel 7 and the adjusting rotating wheel 12 and the fixed rotating wheel 13, and the main rotating wheel 7 is connected to the adjusting rotating wheel 12 and the fixed rotating wheel 13 through the sanding belt 14.

[0021] A three-phase motor 4 is fixedly installed on the left wall of the right end of the inverted L-shaped processing table 1 near the lower side of the front end of the I-shaped fixing frame 2. A main pulley 5 is fixedly sleeved on the rear end output end of the three-phase motor 4. A transmission belt 6 is arranged between the main pulley 5 and the slave pulley 3. The main pulley 5 is connected to the slave pulley 3 through the transmission belt 6. By turning on the three-phase motor 4, its output end drives the transmission belt 6 to rotate, thereby rotating the slave pulley 3 through the transmission belt 6.

[0022] A slave pulley 3 is rotatably mounted on the front side of the middle position of the I-shaped fixing frame 2. The slave pulley 3 and the main rotating wheel 7 are fixedly connected via a transmission shaft, and the rotation of the slave pulley 3 drives the main rotating wheel 7 to rotate.

[0023] A gear positioning base 15 is fixedly installed at the left position of the upper end of the I-shaped fixing frame 2, and the gear to be deburred is fixed by the gear positioning base 15.

[0024] A collection box 16 is fixedly installed at the upper end of the inverted L-shaped processing table 1 at the lower side of the sand belt 14. The front and rear ends of the collection box 16 are fixedly connected to a support frame 17 near the middle of the inclined surface. A scraper plate 18 is fixedly connected to the support frame 17. The scraper plate 18 fits the sand belt 14. The burrs polished off will stay on the surface of the sand belt 14, and then fall into the interior of the collection box 16 when the sand belt 14 rotates to the adjusting wheel 12. Some of the tightly adhered waste chips will also fall under the scraping of the scraper plate 18.

[0025] A cleaning box 19 is placed at the inner bottom of the collection box 16, and a pull-out groove 20 compatible with the cleaning box 19 is provided at the rear end of the collection box 16 near the lower side. Finally, the cleaning box 19 can be directly pulled out from the inside of the collection box 16 through the design of the pull-out groove 20, and the cleaned waste can be centrally processed.

[0026] Working principle:

[0027] When in use, the gear to be deburred is fixed by the gear positioning base 15, and the three-phase motor 4 is turned on to make its output end drive the transmission belt 6 to rotate, thereby rotating the slave pulley 3 through the transmission belt 6, and the main rotating wheel 7 is driven to rotate by the rotation of the slave pulley 3. In combination with the design of the adjusting wheel 12 and the fixed rotating wheel 13, the rotation of the main rotating wheel 7 can drive the sanding belt 14 to rotate, so that the lower surface of the gear is rubbed by the sanding belt 14 to achieve the effect of deburring. Furthermore, by adjusting the position of the adjustable fixing part 8 on the I-shaped fixing frame 2, in combination with the limiting effect of the tension spring 10, a height difference can be formed between the adjusting wheel 12 and the main rotating wheel 7, so that the sanding belt 14 is inclined at a certain angle, and then the edge chamfer position of the gear can be polished and deburred, thereby improving the performance of the device. The deburring effect is good. At the same time, when the tension spring 10 is subjected to a certain force, it has an adaptive adjustment function, which can better avoid the excessive grinding of the gear by the sanding belt 14. In addition, during the deburring process, since the sanding belt 14 and the gear fit closely, the burrs ground off will remain on the surface of the sanding belt 14, and then fall into the inside of the collection box 16 when the sanding belt 14 rotates to the adjusting wheel 12, and some tightly adhered waste chips will also fall under the scraping of the scraper plate 18. Finally, the cleaning box 19 is directly pulled out of the inside of the collection box 16 through the design of the pull-out groove 20, and the cleaned waste chips can be centrally processed. The structure is simple and the operation is convenient. The waste chips can be cleaned while the gear is deburred, which greatly reduces the time for cleaning the waste chips and improves the processing efficiency.
