Description

Technical Field

[0002] An alloy is a substance with metallic properties synthesized by two or more metals and metals or non-metals by a certain method, such as aluminum alloy, zinc alloy, lead-tin alloy, etc. Existing alloys are widely used in various industries, such as aviation, aerospace, automotive, machinery manufacturing, shipbuilding, and chemical industries. After some alloy materials are processed into parts or materials, in order to ensure the quality of the parts or materials, grinding processing is mostly carried out.

The limiting blocks 32 are slidably connected to the limiting grooves 51;

[0041] The side wall of the inner cavity of the grinding support housing 3 is fixedly connected with a cylinder 33. A plurality of abutting blocks 34 are fixedly connected to the cylindrical surface of the cylinder 33 in a circular array. The side of the abutting block 34 away from the cylinder 33 is provided with a slope. The plurality of abutting blocks 34 are respectively distributed in one-to-one correspondence with the plurality of telescopic blocks 5.

[0042] The strip-shaped sliding plate 42 is slidably connected with the strip-shaped groove 22 back and forth. One ends of the adjustment plate 4 and the strip-shaped sliding plate 42 both pass through the sealing plate 26 and extend to the inner cavity of the grinding support housing 3, and the adjustment plate 4 and the strip-shaped sliding plate 42 are both slidably connected with the sealing plate 26 back and forth.

[0043] Please refer to Figure 3 and Figure 5 A connecting groove is formed at the bottom of the telescopic block 5. One end of the movable arm rod 43 away from the adjusting plate 4 is movably inserted into the connecting groove, and the movable arm rod 43 is rotatably connected to the connecting groove through a rotating shaft.

[0044] A docking groove 52 is formed at the end of the telescopic block 5, and a slot 53 is formed at the bottom of the docking groove 52. The lower end of the grinding head 6 is stuck in the docking groove 52, and the insertion plate 61 is inserted into the slot 53.

[0045] By sliding the adjusting plate 4 back and forth along the telescopic groove 21 of the extension arm 2, the adjusting plate 4 drives the strip-shaped sliding plate 42 to slide back and forth along the strip-shaped groove 22, the adjusting plate 4 drives the movable arm rod 43 to rotate, the movable arm rod 43 drives the telescopic block 5 to slide along the lifting hole 31, and the limiting groove 51 on the side of the telescopic block 5 slides along the limiting block 32, so that the telescopic block 5 can slide stably. At the same time, through the cooperation of the limiting block 32 and the limiting groove 51, the telescopic block 5 is limited to prevent the telescopic block 5 from falling off from the lifting hole 31;

[0046] When the adjusting plate 4 is inserted into the inner cavity of the grinding support housing 3, the adjusting plate 4 pushes the telescopic block 5 to extend out of the grinding support housing 3 along the lifting hole 31 through the movable arm rod 43, and the telescopic block 5 drives the grinding head 6 to move away from the grinding support housing 3, so that the grinding head 6 can grind the inner wall of a pipe with a larger diameter;

[0047] When the adjusting plate 4 moves out of the grinding support housing 3, the adjusting plate 4 pulls the telescopic block 5 to insert into the grinding support housing 3 along the lifting hole 31 through the movable arm rod 43, and the telescopic block 5 drives the grinding head 6 to move close to the grinding support housing 3, so that the grinding head 6 can grind the inner wall of a pipe with a smaller diameter;

[0048] The telescopic adjustment mechanism drives the plurality of grinding heads 6 to move, so that the grinding heads 6 can adjust their positions as needed, and thus can grind the inner walls of pipes with different diameters, avoiding frequent replacement of the grinding heads 6.

[0049] Please refer to Figure 2 、 Figure 3 and Figure 5 A movable groove 54 is formed at the bottom of the telescopic block 5, and the movable groove 54 communicates with the slot 53. The locking assembly includes an L-shaped positioning block 63 slidably installed back and forth in the movable groove 54. An elastic piece 64 is installed on the side of the L-shaped positioning block 63. One side of the elastic piece 64 abuts against the side of the movable groove 54. The insertion end of the L-shaped positioning block 63 is set as a slope. A positioning hole 62 is formed on the side of the insertion plate 61. The insertion end with a slope of the L-shaped positioning block 63 is inserted into the positioning hole 62, and the lower end of the L-shaped positioning block 63 passes through the movable groove 54 and extends to the outside.

[0050] When the grinding head 6 is installed, first insert the insertion plate 61 into the slot 53. After the lower end of the insertion plate 61 contacts the slope surface at the end of the L-shaped positioning block 63, the insertion plate 61 pushes the L-shaped positioning block 63 to slide along the movable slot 54, and at the same time, the L-shaped positioning block 63 squeezes the elastic piece 64;

[0051] When the insertion plate 61 is completely inserted into the slot 53, the lower end of the grinding head 6 contacts the bottom of the docking slot 52. At this time, under the action of the elastic force of the elastic piece 64, the end of the L-shaped positioning block 63 is clamped with the positioning hole 62, so as to fix the insertion plate 61 in the slot 53, and further enable the grinding head 6 to be firmly installed in the docking slot 52.

[0052] When the grinding head 6 needs to be disassembled, move the telescopic block 5 into the grinding support housing 3. After the telescopic block 5 drives the L-shaped positioning block 63 to move a certain distance into the inner cavity of the grinding support housing 3, the lower end of the L-shaped positioning block 63 first contacts the slope surface at the upper end of the abutting block 34;

[0053] At this time, the telescopic block 5 continues to drive the L-shaped positioning block 63 to move. By pushing the L-shaped positioning block 63 along the movable slot 54 through the abutting block 34, and at the same time, the insertion end of the L-shaped positioning block 63 is moved out of the positioning hole 62 of the insertion plate 61, so as to release the fixation of the insertion plate 61;

[0054] At this time, pull the grinding head 6 to drive the insertion plate 61 to move out of the slot 53, and then complete the disassembly of the grinding head 6. The installation and disassembly of the grinding head 6 are simple and convenient.

[0055] Please refer to Figure 2 、 Figure 4 、 Figure 6 and Figure 7 , the rotary drive mechanism includes a screw rod 7 threadedly installed in the threaded hole 41. One end of the screw rod 7 away from the adjusting plate 4 is fixedly connected with a round shaft 71. One end of the round shaft 71 away from the screw rod 7 passes through the rotary slot 23 and extends into the rectangular through slot 24. An annular plate 72, an adjusting sleeve 73 and a rotary crown gear 74 are fixedly sleeved on the round shaft 71 in sequence from front to back. The annular plate 72 is in rotational contact with the side wall of the telescopic slot 21. The adjusting sleeve 73 is rotatably installed in the rotary slot 23. The rotary crown gear 74 is in rotational contact with the side wall of the rectangular through slot 24. The annular plate 72 and the rotary crown gear 74 are respectively arranged at both ends of the round shaft 71. By providing the annular plate 72 and the rotary crown gear 74 to limit the position of the round shaft 71, the round shaft 71 can stably rotate along the extension arm 2.

[0056] By rotating the adjusting sleeve 73 to drive the round shaft 71 to rotate, the round shaft 71 drives the screw rod 7 to rotate along the threaded hole 41, so that the adjusting plate 4 slides back and forth along the telescopic slot 21.

[0057] The locking mechanism includes a locking crown gear 8 installed in the rectangular through groove 24. Symmetrically fixed to the left and right sides of the cylindrical surface of the locking crown gear 8 are sliders 81, and symmetrically fixed to the upper and lower sides of the cylindrical surface of the locking crown gear 8 are push plates 82. Inserted into the side of the locking crown gear 8 away from the rotating crown gear 74 is a locking spring 83, and the locking spring 83 abuts against the side of the rectangular through groove 24.

[0058] The locking crown gear 8 is engaged with the rotating crown gear 74. Symmetrically provided on the left and right side walls of the rectangular through groove 24 are sliding grooves 25, and the sliders 81 are slidably connected to the sliding grooves 25 in the front and rear directions.

[0059] Under the action of the elastic force of the locking spring 83, the locking crown gear 8 is engaged with the rotating crown gear 74, thereby locking the rotating crown gear 74, and further preventing the circular shaft 71 and the screw 7 from rotating.

[0060] By providing the locking mechanism to lock the rotating transmission mechanism, when grinding the inner wall of the pipe, it can well prevent the adjusting plate 4 from sliding along the telescopic groove 21, thereby preventing the telescopic block 5 from sliding along the lifting hole 31, and further preventing the grinding head 6 from shaking, so that the grinding head 6 can evenly grind the inner wall of the pipe.

[0061] When it is necessary to rotate the circular shaft 71, first push the push plate 82 to separate the locking crown gear 8 from the rotating crown gear 74. At this time, the adjusting sleeve 73 can be rotated to drive the circular shaft 71 to rotate; the locking crown gear 8 drives the slider 81 to slide along the sliding groove 25, so that the locking crown gear 8 can slide stably. By providing the cooperation of the slider 81 and the sliding groove 25, the locking crown gear 8 and the slider 81 can move back and forth.

[0062] The alloy processing technology includes the following operating steps:

[0063] Step 1: Loading: When grinding, first clamp and fix the pipe through the clamping mechanism, and then drive the clamping mechanism and the pipe to rotate by the pipe rotating driving device, and at the same time align the inner cavity of the pipe with the grinding support housing 3.

[0064] Step 2: Grinding: The piston rod of the hydraulic cylinder 12 extends to drive the support frame 13 to move forward. The support frame 13 drives the sealing plate 26 and the grinding support housing 3 to move forward through the reinforcement plate 15 and the extension arm 2, so that the grinding support housing 3 drives the grinding head 6 to slowly insert into the inner cavity of the pipe, and the inner wall of the pipe is ground by the grinding head 6.

[0065] Step 3: Adjustment: First release the locking of the rotating transmission mechanism by the locking mechanism, drive the telescopic adjustment mechanism to move through the rotating transmission mechanism, so that the telescopic block 5 in the telescopic adjustment mechanism slides along the lifting hole 31, and the telescopic block 5 drives the grinding head 6 to move, so as to adjust the position of the grinding head 6 as needed, so that the grinding head 6 can grind the inner walls of pipes with different diameters.

[0066] Step 4: Replacement: The grinding head 6 and the insertion plate 61 can be conveniently installed and disassembled through the cooperation of the telescopic adjustment mechanism, the locking mechanism, and the abutting block 34, greatly improving the replacement efficiency.

[0067] Working principle: When grinding the inner wall of pipes with different diameters, first push the push plate 82 to separate the locking crown gear 8 from the rotating crown gear 74. The locking crown gear 8 compresses the locking spring 83. By rotating the adjusting sleeve 73, the round shaft 71 is driven to rotate. The round shaft 71 drives the screw 7 to rotate along the threaded hole 41, so that the adjusting plate 4 slides back and forth along the telescopic groove 21. The adjusting plate 4 drives the movable arm rod 43 to rotate, and the movable arm rod 43 drives the telescopic block 5 to slide along the lifting hole 31. The telescopic block 5 drives the grinding head 6 to move. The telescopic adjustment mechanism drives multiple grinding heads 6 to move synchronously, so that the grinding head 6 can be adjusted according to needs, and then the inner wall of pipes with different diameters can be ground, avoiding frequent replacement of the grinding head 6;

[0068] After the adjustment is completed, release the push plate 82. Under the action of the elastic force of the locking spring 83, the locking crown gear 8 is engaged with the rotating crown gear 74, so as to lock the rotating crown gear 74, and further prevent the round shaft 71 and the screw 7 from rotating;

[0069] The rotation transmission mechanism is locked through the set locking mechanism. When grinding the inner wall of the pipe, it can well prevent the adjusting plate 4 from sliding along the telescopic groove 21, so as to prevent the telescopic block 5 from sliding along the lifting hole 31, and further prevent the grinding head 6 from shaking, so that the grinding head 6 can evenly grind the inner wall of the pipe.

[0070] When the grinding head 6 needs to be disassembled, rotate the adjusting sleeve 73 to move the adjusting plate 4 into the telescopic groove 21, so that the telescopic block 5 contracts into the grinding support housing 3. After the telescopic block 5 drives the L-shaped positioning block 63 to move a certain distance into the inner cavity of the grinding support housing 3, the lower end of the L-shaped positioning block 63 first contacts the slope on the upper end of the abutting block 34. The L-shaped positioning block 63 is pushed by the abutting block 34 to slide along the movable groove 54, so that the insertion end of the L-shaped positioning block 63 is removed from the positioning hole 62 of the insertion plate 61, thus releasing the fixation of the insertion plate 61;

[0071] At this time, pull the grinding head 6 to drive the insertion plate 61 out of the slot 53, and then complete the disassembly of the grinding head 6;

[0072] During installation, first slide the adjusting plate 4 outward along the telescopic groove 21 for a certain distance to separate the L-shaped positioning block 63 from the abutting block 34. Then insert the insertion plate 61 along the insertion slot 53.
