Description

Technical Field

[0001] This utility model relates to the field of aluminum rod processing technology, specifically to a round surface shaping and grinding device for aluminum alloy rods. Background Technology

[0002] After casting, aluminum bars often have uneven surfaces and burrs due to limitations in production tools. To improve product quality, grinding is often necessary. Aluminum bar grinding can usually be done on a lathe, but lathes occupy a large area, making them inconvenient for smaller processing areas. In such cases, manual grinding is typically used.

[0003] Manual grinding typically involves securing both ends of an aluminum rod with a fixing device. A worker then holds a grinding disc against the side wall of the rod and moves the disc back and forth along its axis. After grinding one side, the worker moves to the other side to continue grinding until all the rounded surfaces at each angle of the rod are finished. This method has several drawbacks: it is cumbersome to operate; the fixing device cannot be adjusted according to the length of the aluminum rod; and cleaning up grinding debris afterwards is inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a round surface shaping and grinding device for aluminum alloy rods, which has the advantages of flexible grinding of aluminum rods, meeting the installation needs of aluminum rods of different lengths, and convenient post-grinding debris cleaning.

[0005] The technical solution of this utility model is as follows:

[0006] A circular surface shaping and grinding device for aluminum alloy rods includes a fixed frame, which is rectangular. A slide rail running left-right is provided on the top of the fixed frame. A sliding plate is slidably connected to the slide rail. Fixing screws for securing the fixed frame are provided at both ends of the sliding plate. Rotating blocks are rotatably connected to the left ends of the fixed frame and the sliding plate, respectively. The rotation axes of the rotating blocks are coaxial and flush with the opening of the top plate of the fixed frame. Each of the two rotating blocks has a fixing component A on its opposite surface for fixing the end of the aluminum rod. A handle A is rotatably connected to the left end of the fixed frame, and the rotation axis of the handle A is coaxial with the rotating block. Next, the throttle A is provided with a fixing component B for fixing the throttle angle. The fixing frame is rotatably connected to a threaded rod in the left-right direction below the rotating block. The left end of the fixing frame is rotatably connected to the throttle B. The rotating shaft of the throttle B is coaxially connected to the left end of the threaded rod. A translation plate is threadedly connected to the threaded rod. The inner wall of the fixing frame is provided with a sliding groove in the left-right direction. The end of the translation plate is slidably connected to the sliding groove. A mounting plate is detachably connected to the translation plate. A grinding disc is provided on the top of the mounting plate. A waste collection box is detachably connected to the bottom of the fixing frame. The bottom opening of the fixing frame is connected to the top opening of the waste collection box.

[0007] Preferably, the fixing component A includes a bidirectional screw, a threaded sleeve, a clamping plate, a knob, and a fastening nut. The bidirectional screw is rotatably connected to the rotating block, and the rotation axis of the rotating block intersects perpendicularly with the midpoint of the bidirectional screw. A pair of threaded sleeves are symmetrically threaded onto the bidirectional screw. The rotating block has a slide rail in the same direction as the bidirectional screw, and the threaded sleeve is slidably connected to the slide rail. The threaded sleeve has a clamping plate. One end of the bidirectional screw extends out of the rotating block, and a knob is fixedly connected to the outer end of the bidirectional screw. A fastening nut is threaded onto the threaded portion of the outer end of the bidirectional screw.

[0008] Preferably, the fixing component B includes a fixing plate, a fixing rod, a sliding sleeve, and a spring. The fixing plate is provided on the rotating shaft of the throttle A. The fixing plate is provided with a fixing rod pointing to the left end of the fixing frame. The sliding sleeve is slidably connected to the fixing rod. A spring is provided between the sliding sleeve and the fixing plate. The spring is sleeved on the fixing rod. Several pairs of interfaces are evenly provided around the rotation axis of the rotating block at the left end of the fixing frame. The shape of the pairs of interfaces is similar to the shape of the end of the sliding sleeve facing the fixing frame.

[0009] Preferably, the mounting plate has a pair of symmetrical insert rods at the bottom, and the insert rods have several through holes evenly distributed along the height direction. The sliding plate has a socket for inserting the insert rods, and a connecting screw is threaded onto the socket. The sliding plate and the mounting plate can be detachably connected by rotating the connecting screw to insert it into the aligned through hole.

[0010] Preferably, the bottom of the fixing frame and the top of the waste collection box are each provided with corresponding screw holes at their joints, and the detachable connection between the fixing frame and the waste collection box is achieved by screwing connecting screws into the overlapping screw holes.

[0011] The beneficial technical effects of this utility model are as follows:

[0012] 1. Fix both ends of the aluminum rod with the fixing component A on the two rotating blocks. Change the angle of the aluminum rod by rotating the handle A and fix it with the fixing component B. Move the grinding disc back and forth by rotating the handle B to process the aluminum rod on the lower side, so that the round surface of the aluminum rod at all angles is polished.

[0013] When adjusting the angle of the aluminum rod, first loosen the fixing component B, then hold the handle A and turn it. The turning handle A drives the connected rotating block to rotate, and the rotating block drives the connected aluminum rod to rotate synchronously. Finally, tighten the fixing component B again to fix the aluminum rod at the new angle. When moving the grinding disc, hold the handle B and turn it. The turning handle B drives the connected threaded rod to rotate, and the rotating threaded rod drives the translation plate to move in the left and right direction. The moving translation plate drives the connected mounting plate and the grinding disc on the mounting plate to move accordingly. The grinding disc grinds the aluminum rod on the next side, thus achieving the grinding process of the aluminum rod.

[0014] 2. The distance between the two rotating blocks can be adjusted by moving the sliding plate to meet the fixing needs of aluminum rods of different lengths. The sliding plate and the mounting plate are detachably connected, which facilitates the replacement and maintenance of the grinding disc.

[0015] 3. The area of ​​the aluminum rod being ground is lower than the top opening of the fixed frame, which reduces the risk of grinding debris flying outwards. The bottom of the grinding fixed frame is equipped with a connected waste collection box, and the debris ground off the aluminum rod by the grinding disc can fall into the waste collection box, making it easy to clean up afterwards.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] Example:

[0026] like Figures 1 to 6As shown, this embodiment provides a round surface shaping and grinding device for aluminum alloy rods, including a fixed frame 1, which is rectangular. The top of the fixed frame 1 is provided with a slide rail 2 along the left-right direction. A sliding plate 3 is slidably connected to the slide rail 2. The front and rear ends of the sliding plate 3 are provided with fixing screws 4 for abutting against the fixed frame 1. The left end of the fixed frame 1 and the left end of the sliding plate 3 are each rotatably connected with a rotating block 5. The rotation axis of the rotating block 5 is on the same straight line and flush with the opening of the top plate of the fixed frame 1. The two rotating blocks 5 are each provided with a fixing component A6 for fixing the end of the aluminum rod on their opposite surfaces. A handle A7 is rotatably connected to the left end of the fixed frame 1. The rotating shaft of the handle A7 is coaxial with the rotating block 5. Next, the throttle A7 is provided with a fixing component B8 for fixing the throttle angle. The fixing frame 1 is rotatably connected to a threaded rod 9 in the left and right direction below the rotating block 5. The left end of the fixing frame 1 is rotatably connected to the throttle B10. The throttle B10 shaft is coaxially connected to the left end of the threaded rod 9. The threaded rod 9 is threadedly connected to a translation plate 11. The inner wall of the fixing frame 1 is provided with a sliding groove 12 in the left and right direction. The end of the translation plate 11 is slidably connected to the sliding groove 12. The translation plate 11 is detachably connected to a mounting plate 13. The top of the mounting plate 13 is provided with a grinding disc 14. The bottom of the fixing frame 1 is detachably connected to a waste collection box 15. The bottom opening of the fixing frame 1 is connected to the top opening of the waste collection box 15.

[0027] The two ends of the aluminum rod are fixed by the fixing components A6 on the two rotating blocks 5. The angle of the aluminum rod is changed by rotating the handle A7 and fixed by the fixing component B8. The grinding disc 14 is moved back and forth by rotating the handle B10 to process the aluminum rod on the lower side, so that the circular surface of the aluminum rod at all angles is ground. When adjusting the angle of the aluminum rod, first release the fixing component B8, then hold the handle A7 and rotate it. The rotating handle A7 drives the connected rotating block 5 to rotate, and the rotating block 5 drives the connected aluminum rod to rotate synchronously. Finally, the fixing component B8 is tightened again to fix the aluminum rod at the new angle. When moving the grinding disc 14, hold the handle B10 and rotate it. The rotating handle B10 drives the connected threaded rod 9 to rotate. The rotating threaded rod 9 drives the translation plate 11 to move in the left and right direction. The moving translation plate 11 drives the connected mounting plate 13 and the grinding disc 14 on the mounting plate 13 to move accordingly. The grinding disc 14 grinds the aluminum rod on the lower side, realizing the grinding process of the aluminum rod. The distance between the two rotating blocks 5 can be adjusted by moving the sliding plate 3 to meet the fixing needs of aluminum rods of different lengths. The translation plate 11 and the mounting plate 13 are detachably connected, which facilitates the replacement and maintenance of the grinding disc 14. The part of the aluminum rod to be ground is lower than the top opening of the fixing frame 1, which reduces the risk of grinding debris flying outward. The bottom of the grinding fixing frame 1 is equipped with a connected waste collection box 15, and the debris ground off the aluminum rod by the grinding disc 14 can fall into the waste collection box 15, which is convenient for cleaning afterward.

[0028] Furthermore, the fixing component A6 includes a bidirectional screw 16, a threaded sleeve 17, a clamping plate 18, a knob 19, and a fastening nut 20. The bidirectional screw 16 is rotatably connected to the rotating block 5. The rotation axis of the rotating block 5 intersects perpendicularly with the midpoint of the bidirectional screw 16. A pair of threaded sleeves 17 are symmetrically threaded onto the bidirectional screw 16. The rotating block 5 is provided with a slide rail 21 in the same direction as the bidirectional screw 16. The threaded sleeve 17 is slidably connected to the slide rail 21. The threaded sleeve 17 is provided with a clamping plate 18. One end of the bidirectional screw 16 extends out of the rotating block 5. The knob 19 is fixedly connected to the outer end of the bidirectional screw 16. The fastening nut 20 is threaded onto the threaded portion of the outer end of the bidirectional screw 16.

[0029] When the operator turns knob 19, the rotation of knob 19 drives the bidirectional screw 16 to rotate. The rotating bidirectional screw 16 drives two symmetrically arranged threaded sleeves 17 to move synchronously in opposite directions, realizing the closing and opening of the two clamping plates 18. The two clamping plates 18 clamp the end of the aluminum rod. The center of symmetry of the two threaded sleeves 17 is passed through the rotation axis of the rotating block 5, which facilitates the alignment of the central axis of the aluminum rod with the rotation axis of the rotating block 5. After adjusting the position of the clamping plates 18, the fastening nut 20 is rotated to press against the rotating block 5, limiting the rotational capacity of the bidirectional screw 16 and reducing the risk of the clamping plates 18 loosening.

[0030] Furthermore, the fixing component B8 includes a fixing plate 22, a fixing rod 23, a sliding sleeve 24, and a spring 25. The fixing plate 22 is provided on the rotating shaft of the throttle A7. The fixing rod 23 pointing to the left end of the fixing frame 1 is provided on the fixing plate 22. The sliding sleeve 24 is slidably connected to the fixing rod 23. The spring 25 is provided between the sliding sleeve 24 and the fixing plate 22. The spring 25 is sleeved on the fixing rod 23. Several pairs of interfaces 26 are evenly provided around the rotation axis of the rotating block 5 at the left end of the fixing frame 1. The shape of the interface 26 is similar to the shape of the end of the sliding sleeve 24 facing the fixing frame 1.

[0031] By allowing the indirectly connected sliding sleeve 24 to extend into the interface 26, the rotation capability of the throttle A7 is limited, thereby limiting the rotation capability of the rotating block 5 connected to the throttle A7, thus fixing the angle of the aluminum rod. The spring 25 provides the elastic force to press the sliding sleeve 24 into the interface 26. In addition, by using the sliding sleeve 24 to extend one by one into the interfaces 26 that are evenly distributed along the circumference, the circular surface of the aluminum rod at each angle has the opportunity to rotate to the downward side, avoiding any parts that are missed during grinding.

[0032] Furthermore, the bottom of the mounting plate 13 is provided with a pair of symmetrical insert rods 27. The insert rods 27 are provided with several through holes 28 evenly distributed along the height direction. The translation plate 11 is provided with a socket 29 for inserting the insert rods 27. A connecting screw 30 is threaded onto the socket 29. The translation plate 11 and the mounting plate 13 can be detachably connected by rotating the connecting screw 30 so that it extends into the aligned through hole 28.

[0033] The height of the grinding disc 14 on the mounting plate 13 is changed by adjusting the length of the part of the insert rod 27 inserted into the socket 29 to meet the grinding needs of aluminum rods of different diameters. After adjusting the position of the insert rod 27, the connecting screw 30 on the socket 29 is screwed in so that it extends into the aligned through hole 28, thereby fixing the position of the insert rod 27.

[0034] Furthermore, the bottom of the fixing frame 1 and the top of the waste collection box 15 are each provided with corresponding screw holes 31 at the joint. The detachable connection between the fixing frame 1 and the waste collection box 15 is achieved by screwing the connecting screws 30 into the overlapping screw holes 31.

[0035] The connecting screw 30 is easy to operate, making it convenient to install and remove the waste collection box 15, thus improving cleaning efficiency.

[0036] Working principle and usage process of this utility model:

[0037] The worker adjusts the height of the grinding disc 14 according to the diameter of the aluminum rod, mounts the end of the aluminum rod onto the rotating block 5 on the left and fixes it with the fixing component A6. Then, the sliding plate 3 is pulled towards the aluminum rod and mounted onto the rotating block 5 on the right, and fixed with the fixing component A6. Then, the fixing screw 4 is tightened so that it abuts against the fixing frame 1 to fix the position of the sliding plate 3. Then, the handle B10 is turned to drive the grinding disc 14 to move in the left and right direction. When the grinding of the aluminum rod on the lower side is completed, the worker pulls out the sliding sleeve 24 from the interface 26 and turns the handle A7 to align the sliding sleeve 24 with the next interface 26. Then, the sliding sleeve 24 is released and, under the action of the spring 25, extends into the aligned interface 26. Then, the handle B10 is turned again to allow the grinding disc 14 to process the part of the aluminum rod that has just turned to the lower side. This process is repeated until the grinding of the round surfaces of the aluminum rod at all angles is completed.

[0038] During the cleanup, the staff removed the waste collection box 15, emptied the accumulated debris, and then reinstalled it into the fixing frame 1.

[0039] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
