DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1 to 3, the present utility model provides a technical solution for a grinding tool and fixture for wheel axle processing: A grinding tool and fixture for wheel axle processing includes a grinding table 1, an L-shaped bracket 9, and a control box 11. Four support legs 6 are installed at the four corners of the bottom of the grinding table 1 in a rectangular array. An enhancing rod is installed between the lower ends of the four support legs 6. A rectangular notch 14 is formed in the middle of the upper surface of the grinding table 1. Two brackets 7 are symmetrically installed on the left and right sides of the rectangular notch 14 in the middle of the upper surface of the grinding table 1 in the transverse direction. Two fixing seats 4 are symmetrically installed on the front and back sides of the rectangular notch 14 in the middle of the upper surface of the grinding table 1 in the longitudinal direction. Two smooth rods 12 are symmetrically installed at both ends between the two fixing seats 4, and a lead screw rotating shaft 15 is rotatably installed in the middle. The thread directions at both ends of the lead screw rotating shaft 15 are opposite. The front end of the lead screw rotating shaft 15 penetrates through the fixing seat 4 and is installed with a crank 5. There are two L-shaped brackets 9. The lower parts of the vertical ends of the two L-shaped brackets 9 are respectively slidably connected to the two smooth rods 12 and are helically connected to the lead screw rotating shaft 15. Between the two clamping arms of the horizontal ends of the two L-shaped brackets 9, a grinding wheel 10 and a rubber idler roller 13 are respectively rotatably installed. Motors 8 are installed on the same side of the two L-shaped brackets 9. The output shafts of the two motors 8 are respectively connected to the rotating shafts of the grinding wheel 10 and the rubber idler roller 13 through flanges. When in use, first, according to the diameter of the wheel axle, rotate the crank 5 to adjust the distance between the grinding wheel 10 and the rubber idler roller 13. Then, start the two motors 8 through the control box 11. Push the wheel axle into the left bracket 7 in sequence. The two motors 8 rotate to drive the grinding wheel 10 and the rubber idler roller 13 to rotate in the same direction but at different speeds to grind the wheel axle. The rotation of the rubber idler roller 13 causes the wheel axle to rotate, and the rotation of the grinding wheel 10 grinds the wheel axle. The rotation of the grinding wheel 10 and the rubber idler roller 13 in the same direction but at different speeds generates a thrust force to make the wheel axle move forward.

[0019] Two L-shaped slide rails 2 are symmetrically installed on the left and right sides of the rectangular notch 14 at the bottom of the grinding table 1. A storage drawer 3 is slidably installed on the two L-shaped slide rails 2 together. Most of the debris generated during grinding will fall into the storage drawer 3 from the rectangular notch 14. Just regularly pull out the storage drawer 3 for cleaning. The control box 11 is installed at the bottom of the grinding table 1 close to the outside of the right support leg 6. The control box 11 is electrically connected to the two motors 8.

[0020] All motors of the present utility model are designed by selecting a small servo motor - model 14HS2408. This model of motor is only for reference by those skilled in the art. Those skilled in the art can select and install and debug motors with the same parameters and functions according to actual production needs. The present utility model will not elaborate.

[0021] When the utility model is in use, first, according to the diameter of the wheel axle, turn the crank 5. The rotation of the crank 5 drives the rotation of the screw shaft 15. The rotation of the screw shaft 15 drives the two L-shaped brackets 9 to move towards the middle. The grinding wheel 10 and the rubber roller 13 move accordingly and stop at the designated position. Then, start the two motors 8 through the control box 11, and push the wheel axle into from the left bracket 7 in sequence. The rotation of the two motors 8 drives the grinding wheel 10 and the rubber roller 13 to rotate at the same direction but different speeds to grind the wheel axle. Most of the debris generated during grinding will fall into the storage drawer 3 through the rectangular notch 14, and the storage drawer 3 can be pulled out regularly for cleaning.

[0022] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
