Description

Technical Field

[0001] The present invention relates to the technical field of polishing and grinding of lost foam green castings, and specifically to a lost foam green casting polishing and grinding device. Background Art

[0002] A lost foam green casting is a workpiece formed by using the lost foam casting technology. The lost foam casting technology is a full-mold casting technology that uses a foam plastic mold with binderless dry sand combined with a vacuum pumping technology, often referred to as "dry sand full-mold casting". Since lost foam green castings often have advantages such as high temperature resistance, few internal defects, and relatively smooth surfaces, lost foam green castings are commonly used in relatively high-temperature and wear-resistant applications such as engine blocks and connectors.

[0003] The Chinese patent application with the publication number CN214054787U discloses a steel casting polishing and grinding device: using a lifting cylinder, a sliding rod, and a moving block, so that the grinding disc moves up and down. The support cylinder, the grinding table, the slide rail, and the slider cooperate to make the grinding table move up and down. The heights of both the grinding table and the grinding disc can be adjusted, which can effectively and accurately control the grinding thickness and improve the precision of grinding and polishing. The slope is matched with the chip storage groove to clean the waste chips in time.

[0004] Using the above patent application can also perform grinding treatment on lost foam green castings, and still has advantages such as timely cleaning of waste chips and the equipment always remaining clean. However, there are still the following defects: 1. The above patent application can only perform polishing and grinding treatment on a single casting during use. Therefore, the above patent application has a low efficiency during the grinding process of the casting, affecting the forming efficiency of the casting.

[0005] 2. The above patent application does not clean the waste chips on the surface of the grinding disc during the grinding process. Therefore, the waste chips adhered to its surface during the grinding process of the grinding disc may cause scratches on the casting, thus affecting the forming quality of the casting.

[0034] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following detailed description of the specific embodiments of the present invention is provided in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0035] Refer to Figure 1 and Figure 2 , a lost foam green casting polishing and grinding device, including a placing disc 1. A rotating shaft 2 extending up and down is rotatably installed in the middle of the upper end surface of the placing disc 1 through a bearing. A storage mechanism 4 for placing a connecting piece 3 is installed on the upper end surface of the placing disc 1. A ring-shaped frame 5 is installed on the circumferential surface of the placing disc 1, and a grinding mechanism 6 for grinding the connecting piece 3 is installed on the ring-shaped frame 5.

[0036] Refer to Figures 2 to 4 , the storage mechanism 4 includes an adjusting disc 41 fixed on the rotating shaft 2. A plurality of adjusting grooves 42 are circumferentially and evenly formed on the circumferential surface of the adjusting disc 41. Storage blocks 43 corresponding to the adjusting grooves 42 one by one and capable of automatic reset are slidably arranged along the radial direction of the upper end surface of the placing disc 1. An adjusting rod 45 is installed at one end of the storage block 43 close to the rotating shaft 2, and the other end of the adjusting rod 45 away from the storage block 43 is arranged inside the corresponding adjusting groove 42. A limiting part 46 for pressing and limiting the connecting piece 3 is installed on the rotating shaft 2.

[0037] Refer to Figure 6, the storage block 43 is composed of a rectangular block one 431 and a rectangular block two 432 distributed from top to bottom. The rectangular block one 431 is slidably arranged on the upper end surface of the rectangular block two 432 and can be automatically reset. A circular protrusion 433 and a circular groove 434 for limiting the connecting piece 3 are arranged on the upper end surface of the rectangular block one 431 along the radial direction of the placing disc 1 from inside to outside, and the adjusting rod 45 is fixed at one end of the rectangular block two 432 close to the rotating shaft 2.

[0038] Refer to Figure 1 and Figure 7 , the grinding mechanism 6 includes a rotating shaft 61 rotatably installed on the upper end surface of the annular frame 5 and corresponding to the storage block 43 one by one. A supporting disc 62 for placing the connecting piece 3 is installed on the upper side of the circumferential surface of the rotating shaft 61. A grinding disc 63 is detachably installed on the rotating shaft 61. A sprocket 64 is fixedly installed on the lower side of the circumferential surface of the rotating shaft 61. A cleaning part 65 for cleaning the waste chips on the surface of the grinding disc 63 is installed on the upper end surface of the annular frame 5.

[0039] Refer to Figure 9 , where the connecting piece 3 is composed of a rectangular section 31 and a U-shaped connecting section 32. A through connecting hole 33 and symmetric connecting protrusions 34 are arranged on the rectangular section 31. One side of the adjusting groove 42 along the rotating direction of the rotating shaft 2 is set as an inclined plane. A reset spring rod for resetting the rectangular block two 432 is installed between the rectangular block two 432 and the placing disc 1. An elastic telescopic rod for resetting the rectangular block one 431 is installed on the rectangular block two 432.

[0040] During specific operation, the connecting piece 3 is placed on the rectangular block one 431, and the connecting hole 33 and the connecting protrusion 34 are respectively placed on the circular protrusion 433 and the circular groove 434. At this time, the connecting piece 3 is limited on the rectangular block one 431. The rotating shaft 2 is driven to rotate by an external force (manual twisting or driving motor). During the rotation of the rotating shaft 2 driving the adjusting disc 41, the inclined plane inside the adjusting groove 42 and the adjusting rod 45 cooperate with each other to drive the storage block 43 to move outward along the radial direction of the placing disc 1. At this time, the reset spring rod is stretched, and the storage block 43 drives the connecting piece 3 to move outward. The connecting section 32 of the connecting piece 3 is attached to the grinding disc 63.

[0041] Refer to Figure 5, the limiting part 46 includes a lifting disc 461 installed on the rotating shaft 2 by means of threads. A plurality of limiting frames 462 corresponding to the storage blocks 43 one by one and having a T-shaped structure are arranged on the circumferential surface of the lifting disc 461. The longer section of the limiting frame 462 is fixedly connected to the lifting disc 461, and the shorter section of the limiting frame 462 is located between the circular protrusion 433 on the corresponding rectangular block one 431 and the circular groove 434 on the corresponding rectangular block one 431. A plurality of rotating rollers 463 are evenly installed on the lower end surface of the shorter section of the limiting frame 462 through bearings.

[0042] Continue to refer to Figure 5 , an L-shaped limiting connecting frame 11 is arranged on the upper end surface of the placing disc 1. The vertical section of the limiting connecting frame 11 is fixed on the upper end surface of the placing disc 1, and the horizontal section of the limiting connecting frame 11 is located between the adjusting disc 41 and the lifting disc 461. A limiting rod 464 is slidably arranged through the lifting disc 461, and the lower end of the limiting rod 464 is fixed on the upper end surface of the horizontal section of the limiting connecting frame 11.

[0043] The distance between the limiting frame 462 and the storage block 43 is large enough. When the rotating shaft 2 drives the storage block 43 to move outwards through the cooperation of the adjusting disc 41 and the adjusting rod 45, at this time, the rotating shaft 2 drives the lifting disc 461 to move down a certain distance through a threaded connection method, but at this time, the lifting disc 461 is still located above the connecting piece 3. When the adjusting rod 45 moves out of the adjusting groove 42, the adjusting rod 45 abuts against the circumferential surface of the adjusting disc 41 and moves. At this time, the adjusting rod 45 no longer drives the storage block 43 to move outwards. The limiting rod 464 and the limiting connecting frame 11 cooperate with each other to limit the lifting disc 461, avoiding the synchronous rotation of the lifting disc 461 driven by the rotating shaft 2 during the rotation process. During the subsequent reciprocating movement of the rectangular block one 431, the rotating roller 463 can reduce the friction between the rectangular block one 431 and the shorter section of the limiting frame 462.

[0044] Refer to Figure 4 , a vertically extending limiting round rod 411 is slidably arranged through the upper end surface of the adjusting disc 41. A limiting hole 412 matching the limiting round rod 411 is opened on the upper end surface of the placing disc 1 and on the side of the limiting frame 462 close to the limiting round rod 411.

[0045] The rotating shaft 2 continues to rotate, and during the rotation of the rotating shaft 2, the lifting disc 461 is driven to move downward through the threaded connection. During the downward movement of the lifting disc 461, the limiting frame 462 is simultaneously driven to move downward. When the rotating shaft 2 drives the limiting round rod 411 to fall into the limiting hole 412 through the adjusting disc 41, the limiting round rod 411 just fits with the limiting frame 462. At this time, the rotating shaft 2 stops rotating, and the shorter section of the limiting frame 462 just presses and limits the connecting member 3, thereby improving the locking and limiting effect of the connecting member 3. The limiting round rod 411 cooperates with the limiting hole 412 through the adjusting disc 41 to ensure that the rotating shaft 2 will not rotate relative to each other during the subsequent grinding process, thereby improving the stability of the rotating shaft 2.

[0046] After the connector 3 is limited and fixed, a chain is installed between all the sprockets 64. At this time, any one of the rotating shafts 61 is driven to rotate by an external driving motor (not shown in the figure). During the rotation of the rotating shaft 61, the chain and the sprocket 64 cooperate with each other to drive the remaining rotating shafts 61 to rotate. During the rotation of the rotating shaft 61, the grinding disc 63 is driven to rotate to grind the connection section 32 of the connector 3 between the two horizontal sections.

[0047] See also Figure 6 as well as Figure 7 A toggle rod 435 is installed at one end of the rectangular block 431 away from the rotating shaft 2, and a cam 436 matching with the toggle rod 435 is installed on the circumferential surface of the rotating shaft 61 and located between the supporting disc 62 and the sprocket 64.

[0048] Since the grinding disc 63 is a circular structure, the grinding disc 63 may not be in full contact with the two horizontal sections of the connecting section 32 of the connecting member 3 during the grinding process. The rotating shaft 61 rotates and synchronously drives the cam 436 to rotate. During the rotation of the cam 436, the toggle block and the elastic telescopic rod drive the rectangular block 1 431 to reciprocate on the rectangular block 2 432. During the reciprocating movement of the rectangular block 1 431, the connecting member 3 can be driven to reciprocate. Therefore, the above steps can increase the contact area between the reciprocating connecting section 32 of the connecting member 3 and the grinding disc 63, thereby improving the grinding and polishing effect of the connecting member 3.

[0049] See also Figure 7 The cleaning part 65 includes a cleaning frame 651 which cooperates with the grinding disc 63 and has an I-shaped structure, wherein a lockable and limited reversing rod 652 is fixedly installed on the lower end surface of the horizontal section below the cleaning frame 651, and the reversing rod 652 is rotatably installed on the annular frame 5 at one end away from the cleaning frame 651.

[0050] A magnet (not shown in the figure) is installed on the cleaning frame 651. The two horizontal sections of the cleaning frame 651 on either side are in contact with the upper and lower surfaces of the grinding disc 63. During the rotation of the grinding disc 63, the cleaning frame 651 and the magnet cooperate with each other to adsorb and scrape the waste chips generated by grinding adhered to the surface of the grinding disc 63, avoiding the waste chips from scratching the connecting piece 3 during the rotation of the grinding disc 63 and improving the grinding and polishing effect of the connecting piece 3. At the same time, the two horizontal sections of the cleaning frame 651 can limit the position of the grinding disc 63, improving the stability of the grinding disc 63 during rotation.

[0051] Refer to Figure 8 , the reversing rod 652 is composed of two vertical round rods with different diameters, and the diameter of the lower vertical round rod is larger than that of the upper vertical round rod. The upper vertical round rod is fixedly connected to the lower horizontal section of the cleaning frame 651, and the lower vertical round rod is rotatably connected to the annular frame 5.

[0052] Symmetric fixing protrusions 6521 are installed on the lower vertical round rod. The fixing protrusions 6521 are distributed radially along the annular frame 5, and a limiting connection hole 6522 is opened through the upper end surface thereof. A vertically extending limiting link 6523 is slidably arranged on the limiting connection hole 6522 of the fixing protrusion 6521 close to the placing disc 1 side, and the lower end of the limiting link 6523 is clamped with the annular frame 5.

[0053] When a certain amount of waste chips adhere to the magnet on the cleaning frame 651, in order to improve the adhesion effect of the magnet, it is necessary to clean the waste chips adhered to the surface of the magnet. At this time, the limiting link 6523 is pulled out and the vertical round rod is rotated 180 degrees. At this time, the horizontal section on the other side of the cleaning frame 651 is in contact with the grinding disc 63. At this time, the symmetrically arranged fixing protrusions 6521 are swapped in position, and then the limiting link 6523 is passed through the limiting connection hole 6522 and clamped on the annular frame 5, and the waste chips adhered to the cleaning frame 651 are scraped off manually.

[0054] Refer to Figure 7 , a limiting groove is opened on the grinding disc 63, and a limiting protrusion 611 matching the limiting groove is arranged on the upper side of the circumferential surface of the rotating shaft 61. When the grinding disc 63 is severely worn, at this time, the limiting link 6523 is removed, the vertical round rod is rotated 90 degrees to separate the cleaning frame 651 from the grinding disc 63, and then the grinding disc 63 is taken out from the rotating shaft 61. The limiting protrusion 611 and the limiting groove cooperate with each other to fix the grinding disc 63 on the rotating shaft 61, avoiding relative rotation of the grinding disc 63 on the rotating shaft 61.

[0055] After the connecting piece 3 is polished, remove the limiting round rod 411, and rotate the rotating shaft 2 in the reverse direction. At this time, the limiting part 46 is reset first. After the limiting part 46 is reset, the adjusting rod 45 re-enters the corresponding adjusting groove 42 through the reset spring rod. At this time, the storage block 43 is reset synchronously, and the connecting piece 3 is removed one by one manually.

[0056] In the process of polishing, grinding and detecting the lost foam green casting of the present invention, the following steps are included: The first step: Place the connecting piece 3 on the first rectangular block 431 so that the connecting hole 33 and the connecting protrusion 34 are respectively placed on the circular protrusion 433 and the circular groove 434. At this time, the connecting piece 3 is limited on the first rectangular block 431. Drive the rotating shaft 2 to rotate by an external force (manual screwing or driving motor). During the rotation of the rotating shaft 2 driving the adjusting disc 41, the inclined slope inside the adjusting groove 42 and the adjusting rod 45 cooperate with each other to drive the storage block 43 to move outward along the radial direction of the placing disc 1. At this time, the reset spring rod is stretched, and the storage block 43 drives the connecting piece 3 to move outward, and the connecting section 32 of the connecting piece 3 is attached to the grinding disc 63.

[0057] The second step: When the rotating shaft 2 drives the storage block 43 to move outward through the cooperation of the adjusting disc 41 and the adjusting rod 45, at this time, the rotating shaft 2 synchronously drives the lifting disc 461 to move downward a certain distance by means of threaded connection. However, at this time, the lifting disc 461 is still above the connecting piece 3. When the adjusting rod 45 moves out of the adjusting groove 42, the adjusting rod 45 abuts against the circumferential surface of the adjusting disc 41 and moves. At this time, the adjusting rod 45 no longer drives the storage block 43 to move outward.

[0058] The third step: The rotating shaft 2 continues to rotate. During the rotation of the rotating shaft 2, it drives the lifting disc 461 to move downward by means of threaded connection. During the downward movement of the lifting disc 461, it synchronously drives the limiting frame 462 to move downward. When the rotating shaft 2 drives the limiting round rod 411 to fall into the limiting hole 412 through the adjusting disc 41, the limiting round rod 411 just fits with the limiting frame 462. At this time, the rotating shaft 2 stops rotating, and the shorter section of the limiting frame 462 just presses and limits the connecting piece 3.

[0059] The fourth step: After the connecting piece 3 is limited and fixed, install a chain between all the sprockets 64. At this time, drive any one of the rotating shafts 61 to rotate by an external driving motor (not shown in the figure). During the rotation of this rotating shaft 61, the remaining rotating shafts 61 are driven to rotate through the cooperation of the chain and the sprockets 64. During the rotation of the rotating shaft 61, the grinding disc 63 is driven to rotate to grind the two horizontal sections of the connecting section 32 of the connecting piece 3.
