Description

[0002] After rough machining of arc-shaped workpieces, there will be many burrs on the outer circumference of the workpiece. At this time, the burrs need to be polished to meet the use requirements. Most manufacturers polish the burrs on the circumference of the workpiece manually, which is very inefficient. In addition, a large amount of waste chips generated during the grinding process will splash everywhere, not only splashing on the ground and causing employees to slip, but also some waste chips splashing on the staff, and even splashing into the eyes of the staff, causing great harm to the staff.

[0003] However, there are still some problems in the process of grinding curved plates: on the one hand, the traditional manual grinding method is inefficient and labor-intensive, and it is difficult to ensure the stability and consistency of the grinding quality. On the other hand, although some mechanical grinding equipment uses grinding rollers to grind curved plates on a single side, which improves the grinding quality to a certain extent, they are usually unable to adapt to different curved surfaces, resulting in uneven grinding of curved plates, which also greatly limits the improvement of the overall grinding efficiency of curved plates.

When the driving disk 104a rotates, the rotating blocks 104i cannot rotate under the limit of the limiting rotating groove 104b.

[0036] Furthermore, the engaging member 103i includes an engaging block 103i-1, a push plate 103i-2 fixedly connected to one end of the engaging block 103i-1, two sets of limiting clamps 103i-3 symmetrically arranged at both ends of the push plate 103i-2, a limiting telescopic groove 103i-4 arranged at the bottom of the limiting clamp 103i-3, an extrusion spring 103i-5 fixedly connected to the top of the limiting telescopic groove 103i-4, and a locking block 103i-6 fixedly connected to the bottom of the extrusion spring 103i-5.

The extrusion spring 103i-5 is in a contracted state, driving the locking block 103i-6 to be inside the limiting telescopic slot 103i-4. When the locking block 103i-6 and the locking slot 103c are parallel, the extrusion spring 103i-5 loses the elastic force converted from the extrusion force and pushes the locking block 103i-6 to move into the inside of the locking slot 103c, locking the locking piece 103i, and limiting the two groups of grinding plates 103h in the plug-in state to maintain stability during grinding.

[0038] Furthermore, the limiting groove 102d is arranged in an arc shape, and the limiting groove 102d is arranged around the outer wall of the limiting shaft 102c, the abutting column 102e is adapted to the limiting groove 102d, the bottom of the limiting plate 102h is fixedly connected to the top of the processing plate 101a, the limiting slider 102g is adapted to the limiting slide groove 102i, and the first bevel gear 101e is meshed with the second bevel gear 102a.

[0042] When in use, the arc-shaped member is fixed, and the adjusting rod 105h is rotated to make the adjusting rod 105h rotate and move upward under the limit of the telescopic rod 105g connected by thread, and the pushing plate 105i fixedly connected in the middle drives the shrinking plate 105j to move upward, pulling the fixed collar 105c at the top to move upward under the limit of the movable fixed plate 105a, releasing the protection restriction at the top, squeezing the arc-shaped member to squeeze the bottom and the several groups of fixed squeezing plates 105e at the top to shrink inward, squeezing the fixedly connected return spring 105d to move forward. The arc-shaped member is completely placed in the fixed space. The return spring 105d of the arc-shaped member is released and the elastic force converted from the extrusion force pushes the fixed extrusion plate 105e to move to the initial position within the limit of the fixed groove 105b. The fixed extrusion plate 105e is pushed by the return spring 105d to keep the arc-shaped member and the fixed ring 105c in a fixed state.

[0043] The grinding assembly 103 is driven to perform grinding movement, and the driving motor 101c is started to drive the driving rod 101d to rotate, so that the first bevel gear 101e fixedly connected to one end of the driving rod 101d rotates, and the meshed second bevel gear 102a rotates, so that the rotating shaft 102b fixedly connected to the top of the second bevel gear 102a rotates along, and the limiting shaft 102c fixedly connected to the top of the rotating shaft 102b rotates, and is in an arc state in the middle of the limiting shaft 102c The abutting column 102e under the internal limit of the limit groove 102d performs reciprocating motion up and down under the push of the limit groove 102d when the limit groove 102d rotates. The lifting plate 102f fixedly connected to one end of the abutting column 102e is placed under the vertical limit of the two sets of limit slide grooves 102i through the two sets of limit sliders 102g fixedly connected, and the limit is maintained during the up and down movement. The two sets of grinding plates 103h are installed inside the lifting plate 102f through the cooperation of the T-shaped plug rod 103d and the T-shaped plug groove 103a. , push the push plate 103i-2 to insert into the inside of the engaging groove 103b, the extrusion spring 103i-5 is in a contracted state, driving the locking block 103i-6 to be in the inside of the limiting telescopic groove 103i-4, and when the locking block 103i-6 is moved to a parallel state with the locking groove 103c, the extrusion spring 103i-5 loses the elastic force converted from the extrusion force and pushes the locking block 103i-6 to move into the inside of the locking groove 103c, locking the engaging member 103i, so that the locking member 103i is in an inserted state. The two groups of grinding plates 103h in the connected state are limited to maintain stability during grinding. The grinding plates 103h are in contact with the outer wall of the arc-shaped part when they move up and down. When the arc surface of the outer wall of the arc-shaped part changes inconsistently, an extrusion force is provided to the grinding plates 103h when they move, so that the grinding plates 103h squeeze the fixedly connected contraction spring 103g into the interior of the contraction hole 103f. At the same time, the rebound force of the contraction hole 103f pushes the grinding plates 103h to maintain a close fit with the outer wall of the arc-shaped part.

[0044] The fixing assembly 105 is intermittently rotated to ensure the complete grinding of the arc-shaped part. The rotating shaft 104f rotates following the rotating disk 104g fixedly connected at the bottom. The rotating disk 104g makes a group of fixedly connected rotating blocks 104i located inside the limited rotating groove 104b in the middle of the driving disk 104a through the fixedly connected fixing rod 104h. When the driving disk 104a rotates, the rotating block 104i cannot rotate under the limit of the limited rotating groove 104b. When the rotating push plate 104c rotates to the inclined state and contacts the rotating block 104i, the rotating block 104i rotates along the inclined surface of the rotating push plate 104c to the ejection groove 104d on the side wall of the limited rotating groove 104b, and is ejected through the ejection groove 104d. 04d makes a group of rotating blocks 104i rotate out of the limited rotating groove 104b in the middle of the driving disk 104a. When the rotating disk 104g rotates, the other group of rotating blocks 104i is pushed by the pushing groove 104e at one end of the rotating push plate 104c, and rotates along the inclined surface of the other side of the rotating push plate 104c to the inside of the limited rotating groove 104b. The other side stops rotating due to the blocking of the inner wall of the limited rotating groove 104b, that is, it drives the top fixed disk 105a to rotate intermittently, so that the arc-shaped part inside the fixed disk 105a is polished by the up and down reciprocating motion of the polishing plate 103h, and the side wall rotates after the polishing is completed, to ensure that each surface of the arc-shaped part is completely polished, to ensure the uniformity during polishing.

[0045] In summary, the present invention sets a protection unit, starts the driving component to drive the limit moving component to rotate, and the limit moving component limits the grinding component to perform reciprocating motion up and down. The grinding component adapts to the arc surfaces of different specifications of the arc parts by shrinking, and always keeps a close fit to ensure the uniformity of grinding. The rotating component drives the fixed component to rotate intermittently through the limit, so that arc surfaces of different sizes are completely polished, and it is avoided that unpolished areas appear when the rotation is too fast, which is convenient for subsequent processing and use. The adjustability of the fixed component makes the arc parts of different lengths and specifications be completely fixed, which avoids the occurrence of damage and uneven grinding surfaces caused by offset during the grinding process, thereby improving the grinding efficiency of the staff.
