[0020] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a casting grinding device of the utility model in conjunction with the accompanying drawings.
[0021] like Figures 1 to 4 As shown, a casting grinding device of the utility model comprises a waste box 1 with an opening at the top, and a discharge port 14 for discharging the material inside the waste box 1 is opened on the bottom side wall of the waste box 1. A first pillar 2 is distributed in the waste box 1, and a placement plate 3 for carrying the casting is provided at the top of the first pillar 2, and a clamping device for fixing the casting is provided on the placement plate 3. At the same time, a second pillar 8 is symmetrically provided on the waste box 1 with its center, and the second pillar 8 is located on the outer wall of the waste box 1, and the tops of the two second pillars 8 are connected by a connecting plate 9, and a grinding device 10 for grinding the casting carried on the placement plate 3 is provided on the connecting plate 9, and the burrs and rough edges on the casting are polished by the grinding device 10. Among them, the grinding device 10 includes a first electric push rod 101 arranged on the connecting plate 9, the telescopic end of the first electric push rod 101 is arranged downward, and the first electric push rod 101 is electrically connected to an external power supply. A second motor 102 is provided at the telescopic end of the first electric push rod 101, the second motor 102 is connected to an external power source, and a grinding wheel 103 is provided at the output end of the second motor 102. The first electric push rod 101 drives the second motor 102 and the grinding wheel 103 connected to the second motor 102 to move downward, and the second motor 102 drives the grinding wheel 103 to rotate at a high speed, so as to grind the casting. When the casting is polished, the first electric push rod 101 drives the second motor 102 and the grinding wheel 103 connected thereto to rise to the initial position.
[0022] Among them, the clamping device used to fix the casting on the placement plate 3 and prevent the casting from moving when the grinding device 10 grinds it includes a slide groove 31 symmetrically opened on the placement plate 3, a connecting block 5 is slidably arranged in the slide groove 31, and a clamping plate 4 is arranged on the top surface of the connecting block 5 located on the placement plate 3. A driving device 6 for driving the connecting block 5 to slide is provided on the bottom surface of the placement plate 3. The driving device 6 drives the clamping plates 4 respectively arranged through the two connecting blocks 5 to move relatively close or away, so as to achieve the purpose of clamping or loosening the casting on the placement plate 3. Specifically, the driving device 6 includes a first motor 61 arranged on the bottom surface of the placement plate 3, and the first motor 61 is connected to an external power supply for power supply. Two fixed blocks 63 are provided on the bottom surface of the placement plate 3, and the two fixed blocks 63 are rotatably connected with a positive and negative threaded rod 62, and one end of the positive and negative threaded rod 62 is connected to the output end of the first motor 61. At the same time, the positive and negative threaded rod 62 passes through the two connecting blocks 5, and the two connecting blocks 5 are respectively threadedly connected with the two sections of the thread of the positive and negative threaded rod 62. When the casting is placed on the placement, the first motor 61 is started, and the first motor 61 drives the positive and negative threaded rod 62 to rotate, and the two connecting blocks 5 threadedly connected with the positive and negative threaded rod 62 will drive their corresponding clamping plates 4 to move relatively close, so as to achieve the clamping and fixing of the casting by the two clamping plates 4. Among them, the threaded connection between the positive and negative threaded rod 62 and the two connecting blocks 5 has a self-locking function, which can reduce the force on the first motor 61 when the two connecting blocks 5 clamp the casting through the clamping plates 4, prevent the first motor 61 from being damaged, and increase the service life of the first motor 61. At the same time, the threaded connection between the positive and negative threaded rod 62 and the connecting block 5 can also improve the stability of the clamping plates 4 when clamping the casting.
[0023] As a further improvement, a transmission device 7 is also provided on the bottom surface of the placement plate 3, and the driving device 6 is connected to the two connecting blocks 5 through the transmission device 7. Specifically, the transmission device 7 includes a first slider 71 and a second slider 73 slidably provided on the bottom surface of the placement plate 3, and the first slider 71 is provided with a first connecting rod 72 at both ends, and the second slider 73 is provided with a second connecting rod 74 at both ends. At the same time, the correspondingly arranged first connecting rod 72 and the second connecting rod 74 are rotated and connected to the connecting block 5, and the positive and negative threaded rod 62 penetrates the first slider 71 and the second slider 73, and the first slider 71 and the second slider 73 are respectively threadedly connected with the two sections of threads on the positive and negative threaded rod 62. When the two clamping plates 4 need to work, the first motor 61 can be started, and the first motor 61 drives the positive and negative threaded rod 62 to rotate, and the two sliders threadedly connected with the positive and negative threaded rod 62 will move relative to each other, and the connecting block 5 will also move relative to each other under the action of the first connecting rod 72 and the second connecting rod 74, so as to achieve the effect of relative movement of the two clamping plates 4. The use of the transmission device 7 to connect the driving device 6 with the two connecting blocks 5 can prevent the burrs and burrs that are ground from falling from the slide groove 31 of the placement plate 3 onto the positive and negative threaded rods 62, thereby causing a jam between the positive and negative threaded rods 62 and the connecting blocks 5, resulting in the inability of the clamping plate 4 to fix the casting. It should be noted that the driving device 6 can also be replaced by an electric push rod, and no excessive restrictions are made here.
[0024] Preferably, a second electric push rod 11 with a telescopic end facing downward is provided on the connecting plate 9, and the second electric push rod 11 is electrically connected to an external power supply. An extension plate 13 is provided at the telescopic end of the second electric push rod 11, and a rectangular shield 12 is provided on the extension plate 13, and the shield 12 is slidably arranged in the waste bin 1. When the first electric push rod 101 drives the grinding wheel 103 to move downward through the second motor 102, the second electric push rod 11 drives the shield 12 to move upward from the waste bin 1 through the extension plate 13, so that when the grinding wheel 103 grinds the casting, the burrs and burrs thrown away by the grinding wheel 103 will be blocked by the shield 12, and will fall into the waste bin 1 along the inner wall of the shield 12. After the casting is polished, the first electric push rod 101 drives the grinding wheel 103 to move toward the initial position through the second motor 102, and the second electric push rod 11 drives the shield 12 to move toward the initial position through the extension plate 13.
[0025] like Figure 4 As shown, the bottom plate of the waste bin 1 is tilted. The burrs and rough pieces polished by the grinding wheel 103 will be directly discharged along the bottom plate of the waste bin 1 through the discharge port 14. At the same time, in order to save manual cleaning of the rough edges and burrs attached to the bottom plate of the waste bin 1, a vibration motor 15 is provided on the bottom surface of the bottom plate of the waste bin 1, and the vibration motor 15 is connected to an external power supply.
[0026] Method of use: Place the casting on the placement plate 3, then start the driving device 6, which drives the two connecting blocks 5 to move relatively close to each other through the transmission device 7, and the clamping plates 4 set on the two connecting blocks 5 will also move relatively close to each other, so that the two clamping plates 4 can complete the clamping and fixing of the casting, and then start the grinding device 10, the first electric push rod 101 and the second motor 102 of the grinding device 10 are started at the same time, and the first electric push rod 101 drives the grinding wheel 103 to descend through the second motor 102. When the first electric push rod 101 is working, start the second electric push rod 11, and the second electric push rod 11 drives the shield 12 to rise through the extension plate 13, so that the shield 12 can block and protect the burrs and burrs polished by the grinding wheel 103, and play a protective effect on manual work. In addition, the burrs and burrs blocked by the shield 12 will fall into the waste box 1, reducing the time for manual cleaning of the placement plate 3.
