Description

Technical Field

[0001] This utility model relates to the field of wheel hub casting technology, specifically a deburring device for processing magnesium alloy wheel hub castings. Background Technology

[0002] Magnesium alloy wheels refer to vehicle wheels made of magnesium alloy materials. Due to the low density of magnesium alloy, magnesium alloy wheels are relatively lightweight, which helps to reduce the overall weight of the vehicle. The size of magnesium alloy wheels varies depending on the application. They are mainly manufactured using casting equipment.

[0003] When casting magnesium alloy wheels, burrs of varying sizes are easily generated at the joints of the casting mold. Existing deburring methods for magnesium alloy wheels mainly involve machine cutting or grinding. However, machine cutting may still leave a large number of small burrs when removing burrs. When grinding components for deburring, if larger blocky or flaky burrs are encountered, the processing cycle is often long and inconvenient. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see the appendix Figure 1-5 This application provides the following technical solutions.

[0024] A deburring device for processing magnesium alloy wheel hub castings includes a control arm 1, a drive shaft 2 rotatably mounted on one side of the control arm 1, a deburring base wheel 3 mounted on one side of the drive shaft 2, and a plurality of arc-shaped combination plates 6 arranged on the outer side of the deburring base wheel 3 via an assembly. A plurality of grinding discs 7 are provided on one side of each of the arc-shaped combination plates 6. The assembly includes combination blocks 5. A plurality of anti-detachment slots 4 are symmetrically opened on the outer periphery of the deburring base wheel 3. The plurality of combination blocks 5 are horizontally inserted into the plurality of anti-detachment slots 4, and the combination blocks 5 are arranged in a cross structure. A plurality of arc-shaped combination plates 6 are respectively arranged on one side of the combination blocks 5 penetrating the anti-detachment slots 4. The plurality of arc-shaped combination plates 6 form a circular structure. The plurality of grinding discs 7 are evenly distributed through the combination of the plurality of combination blocks 5 and arc-shaped combination plates 6. When some grinding discs 7 are damaged, the arc-shaped combination plates 6 and combination blocks 5 with the damaged grinding discs 7 can be replaced individually. The arc-shaped combination plates 6 and combination blocks 5 can be made of hard plastic or metal.

[0025] The deburring base wheel 3 has a prismatic assembly groove 9 through its center. The drive shaft 2 has a prismatic structure. The deburring base wheel 3 is fitted onto the drive shaft 2 through the prismatic assembly groove 9. The servo control motor in the control arm 1 can control the drive shaft 2 to rotate at high speed. When the drive shaft 2 rotates, it can drive the deburring base wheel 3 and several combination blocks 5 to rotate synchronously. When the combination blocks 5 drive the grinding discs 7 to rotate, the grinding discs 7 remain taut under the action of centrifugal force. Then, when the control arm 1 controls the grinding discs 7 to approach the magnesium alloy cast wheel hub, the swinging grinding discs 7 can knock off the larger burrs in the form of sheets or blocks. Then, as the grinding discs 7 gradually approach, the small burrs on the wheel hub can be polished smooth.

[0026] The constraint positioning component controls the replacement and fixing of the combined insert 5. The constraint positioning component rotatably inserts into one side of the deburring base wheel 3. The constraint positioning component includes a misalignment ring 10, with several symmetrically arranged corresponding protrusions 11 on its four sides. These protrusions 11 correspond to several combined inserts 5. A concave rotating groove 8 is formed on the side of the deburring base wheel 3 away from the drive shaft 2. The misalignment ring 10 rotatably inserts into the concave rotating groove 8. A spacer plate is sandwiched between two adjacent anti-detachment slots 4 of the deburring base wheel 3. The number and size of the protrusions 11 correspond to those of the spacers. The protrusions 11 are symmetrically arranged on the outer periphery of the misalignment ring 10 outside the concave groove 8. When the protrusions 11 correspond to the spacers, the combination insert 5 can be horizontally pulled out from the anti-detachment slot 4. At this time, the combination insert 5 with a certain number of grinding discs 7 can be replaced individually to reduce maintenance costs. Alternatively, according to the needs, fewer combination inserts 5 can be installed to achieve stable rotation of the deburring base wheel 3 and enable the grinding discs 7 to strike and grind the burrs.

[0027] Each side of the combination plug 5 is provided with a positioning groove 12. A positioning block 13 is provided on the side of the corresponding protrusion 11 near the combination plug 5. Several positioning blocks 13 corresponding to the protrusion 11 are respectively inserted into the positioning grooves 12 of several combination plugs 5. An assembly screw groove 14 is provided at the center of the side of the drive shaft 2 away from the control arm 1. An installation bolt 15 is threaded into the assembly screw groove 14. The installation bolt 15 passes through the misalignment ring 10 and is provided with a washer 16. One side of the washer 16 is in contact with the anti-slip texture 17, and the side of the washer 16 in contact with the anti-slip texture 17 is provided with anti-slip texture. When the corresponding protrusion 11 corresponds to the combination plug 5, the installation bolt... Bolt 15 is connected to the assembly screw groove 14 of drive shaft 2, which can press and fix the connection posture of the combination plug 5 and the anti-detachment slot 4 by the counter-protrusion 11, and at the same time prevent the combination plug 5 from detaching from the anti-detachment slot 4. Then, with the assistance of the anti-slip texture 17, the connection combination of the deburred base wheel 3 and drive shaft 2 is stable, and the connection state of the misalignment ring 10 and the deburred base wheel 3 is stable. When it is necessary to disassemble the combination plug 5, reverse the mounting bolt 15. When the mounting bolt 15 has not detached from the assembly screw groove 14, the positioning pressure block 13 can detach from the positioning pressure groove 12. At this time, rotate the counter-protrusion 11 to misalign with the combination plug 5, and the combination plug 5 to be replaced can be pulled out horizontally.
