Description

Technical Field

[0001] The invention relates to the technical field of metal casting polishing, in particular to a small metal casting polishing device. Background Art

[0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain objects with a certain shape, size and performance.

[0003] At present, after the traditional bearing sleeve is cast, it is necessary to polish its surface and interior. When polishing, the staff first needs to clamp the bearing sleeve on the fixture, and then use the polishing equipment to polish its surface and interior a little bit. After polishing one side, the staff will remove the bearing sleeve from the fixture, and then turn the bearing sleeve over. After turning over, it will be re-clamped. After clamping, the staff can polish the other side of the bearing sleeve through the polishing equipment.

[0053] Embodiment 3

[0054] like Figure 1-Figure 12 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0055] In order to realize blanking of the polished bearing sleeve, the present embodiment provides the following technical solution:

[0056] The unloading assembly 6 includes a column 61, and the top surface of the mounting plate 1 is fixedly connected to the column 61, and the top surface of the column 61 is fixedly connected to a first U-shaped frame 62, and one side of the first U-shaped frame 62 is fixedly connected to a forward electric telescopic rod 63, and the output end of the forward electric telescopic rod 63 is fixedly connected to a second U-shaped frame 64, and both ends of the top surface of the second U-shaped frame 64 are respectively fixedly connected to an L-shaped material picking rod 65, and one end of the L-shaped material picking rod 65 is provided with an L-shaped slide groove 66, and the other end of the L-shaped material picking rod 65 is provided with a receiving groove 67, and one end of the inner cavity of the receiving groove 67 is rotatably connected to a hook rod 68 through a torsion spring, and the two ends of the top surface of the first U-shaped frame 62 are respectively fixedly connected to an L-shaped conveying rod 69, and one end of the L-shaped conveying rod 69 is located in the L-shaped slide groove 66 and slides.

After the reset, the L-shaped material picking rod 65 is reset. After the reset, under the action of the hook rod 68, the bearing sleeve 3 is removed from the clamping switching assembly 57, and material unloading can be achieved.

[0058] In order to realize the feeding of the bearing sleeve, the present embodiment provides the following technical solution:

[0059] In this embodiment, the auxiliary feeding assembly 2 includes a rotating motor 21 and a rotating rod 22. The top surface of the mounting plate 1 is fixedly connected with the rotating motor 21, and the top surface of the mounting plate 1 is rotatably connected with the rotating rod 22. The output shaft end of the rotating motor 21 is rotatably connected with the rotating rod 22 through a worm and a worm gear. The top surface of the rotating rod 22 is fixedly connected with a cross 23, and the four ends of the cross 23 are respectively installed with positioning components 24.

[0061] The working principle and use process of the present invention:

[0062] In use:

[0063] When in use, first place the bearing sleeve 3 to be polished on the arc plate 242, and limit the two sides of the bearing sleeve 3 by the arc plate 242. When limiting, fix it on the arc plate 242 by the magnet 243. After placement, start the rotating motor 21. When the rotating motor 21 works, it will drive the rotating rod 22 and the cross 23 to rotate, so as to rotate the positioning component 24 with the bearing sleeve 3 to the material taking and polishing mechanism 4, which is convenient for later material taking, and the positioning component 24 where the bearing sleeve 3 is not stored is rotated to the loading position for loading;

[0064] When picking up materials, first, start the switching pneumatic rod 514 in the second switching component 41 to drive the vertical plate 42 to move, at this time, it will drive the clamping and picking component 43 and the inner grinding component 44 to move, when the inner grinding component 44 moves, the inner grinding component 44 can be moved out of the previous bearing sleeve 3, and at the same time, one end of the clamping and picking component 41 moves toward the bearing sleeve 3, when the clamping claw 434 in the clamping and picking component 41 moves into the bearing sleeve 3, stop the second switching component 41, at this time, start the clamping pneumatic rod 435, when the clamping pneumatic rod When 435 is working, it will drive the moving plate 436 to move. As the moving plate 436 moves, the angle of the connecting rod 437 changes, so that the bearing sleeve 3 is clamped by the clamping claw 434. After clamping, the switching pneumatic rod 514 in the second switching component 41 is started, so that the clamping claw 434 drives the bearing sleeve 3 to separate from the arc plate 242. At this time, the switching motor 515 is started, and the vertical plate 42 is driven to rotate by the switching motor, so that the clamping and taking component 43 and the inner grinding component 44 are switched in position. The switching can facilitate the subsequent grinding.

[0065] At this time, the switching pneumatic rod 514 in the first switching component 51 is started. As the switching pneumatic rod 514 works, the first grinding component 55, the second grinding component 56, the clamping switching component 57 and the reciprocating component 57 are driven to move forward as a whole. As the first grinding component 55 moves, the arc-shaped polishing sheet 554 in the first grinding component 55 and the end surface of the bearing sleeve 3 are brought into contact with each other. After contact, the reciprocating motor 581 in the reciprocating component 58 is started. When the reciprocating motor 581 works, the turntable 583 and the cylinder 584 are driven to rotate. When the cylinder 584 rotates, the cylinder 584 is located in the rectangular frame 587 and slides. At the same time, the rectangular frame 587 is driven to reciprocate up and down. As the rectangular frame 587 reciprocates up and down, the reciprocating rack 585 is driven to reciprocate up and down. The movement can drive the reciprocating gear 586 to rotate back and forth, thereby driving the reciprocating rod 54 to rotate back and forth. When the reciprocating rod 54 rotates back and forth, the first grinding assembly 55 and the second grinding assembly 56 will be driven to rotate back and forth as a whole. When the first grinding assembly 55 rotates, the two groups of arc-shaped polishing sheets 554 will be driven to rotate back and forth, and the surface of the bearing sleeve 3 can be polished during the rotation. When the arc-shaped polishing sheets 554 are polishing, the auxiliary motor 555 is required to drive the rotation of the first bidirectional threaded rod 553, thereby driving the two groups of arc-shaped polishing sheets 554 to move toward or away from each other, so that the bearing sleeves 3 with different outer diameters can be polished. When polishing, the pneumatic rod 514 needs to be switched to drive the first grinding assembly 55 to move back and forth, so that the bearing sleeves 3 with different outer diameters can be polished.

[0066] When the outer diameter grinding is completed, at this time, by switching the pneumatic rod 514 and the switching motor 515, the first grinding assembly 55, the second grinding assembly 56 and the switching assembly 57 can be driven to move and rotate, so that the first grinding assembly 55 can be moved away from the bearing sleeve 3, and at the same time, the second grinding assembly 56 is aligned with the bearing sleeve 3. When the second grinding assembly 56 is aligned with the bearing sleeve, at this time, the switching pneumatic rod 514 will drive the second grinding assembly 56 to move into the bearing sleeve 3, so that the outer grinding roller 563 can be inserted into the bearing sleeve 3 to grind the inside of the bearing sleeve 3, and the inner grinding roller 562 is sleeved on the surface of the bearing sleeve 3 to grind its surface;

[0067] After grinding, at this time, the clamping switching assembly 57 is aligned with the bearing sleeve 3 through the first switching assembly 51, and under the action of the switching pneumatic rod 514, the arc clamping block 574 is driven to enter the bearing sleeve, and then, under the action of the expansion motor 575, the two groups of arc clamping blocks 574 are driven to move, so that the bearing sleeve 3 can be clamped. After clamping, at this time, the clamping and picking assembly 43 will no longer clamp the inner cavity of the bearing sleeve 3. At the same time, under the action of the second switching assembly 41, the clamping and picking assembly 43 is moved out of the bearing sleeve 3 and switches positions with the inner grinding assembly 44. After switching positions, it is convenient to remove the next bearing sleeve 3 later. At this time, the second switching assembly 41 will drive the inner grinding assembly 44 to move toward the inner cavity of the bearing sleeve 3. After moving in, at this time, the grinding motor 441 is started, and the grinding motor 441 will drive the grinding roller 443 to rotate, so that the grinding of the bearing sleeve 3 can be achieved.

[0068] After grinding, the inner grinding component 44 will be moved out of the bearing sleeve 3 under the action of the second switching component 41. After moving out, the first switching component 51 will drive the clamping switching component 57 to rotate and rotate the clamping switching component 57 to the unloading component 6. At this time, the forward electric telescopic rod 63 is started. When the forward electric telescopic rod 63 works, it drives the second U-shaped frame 64 to move. As the second U-shaped frame 64 moves, it will drive the L-shaped material picking rod 65 to move outward, so that the hook rod 68 passes over the bearing sleeve 3. At this time, the clamping switching component 57 releases the arc clamping block 574. At this time, the reciprocating movement of the second U-shaped frame 64 will drive the reciprocating movement of the L-shaped material picking rod 65. Under the action of the hook rod 68, the polished bearing sleeve 3 can be removed from the clamping switching component 57, and unloading can be realized.
