Technical Field

[0001] The utility model relates to the technical field of graphite piece grinding, in particular to a graphite piece grinding device with good fixing effect. Background Art

[0002] During the graphite parts processing, the surface treatment of the graphite parts by the grinding device can not only remove burrs and cutting chips on the surface of the graphite parts and optimize the surface smoothness and quality, but also improve the performance and applicability of the graphite material, and promote the effective utilization of resources. Before the grinding device grinds the graphite parts, it is usually necessary to fix the graphite parts to ensure that the graphite parts can remain stable during the processing.

[0003] When the existing graphite grinding device is in operation, a porous vacuum suction cup with relatively good fixing effect is often used to achieve adsorption and limitation of the workpiece. However, considering that in some cases, the device will grind some small-sized graphites, the small-sized graphite parts cannot completely cover the suction holes. The dust generated when the device is running is very likely to diffuse and block the suction port and affect the fixing effect. The stability of the device during subsequent grinding and processing of graphite parts will also be relatively affected. Therefore, a graphite part grinding device with good fixing effect is proposed to address the above problems. Utility Model Content

[0008] Preferably, a DC motor is fixedly installed at the middle position of the top of the dust cover, and the output end of the DC motor passes through the dust cover and is fixedly connected to the grinding turntable body. The grinding turntable body and the graphite part body are relatively arranged in upper and lower positions.

[0009] Preferably, the vacuum pump body is fixedly connected to a first limiting vertical plate on a side away from the center position of the cross groove, the first limiting vertical plate is fixedly connected to a spring on a side away from the vacuum pump body, the spring is fixedly connected to a second limiting vertical plate on a side away from the first limiting vertical plate, the first limiting vertical plate and the cross groove are slidingly connected, the cross groove and the second limiting vertical plate are fixedly connected, and the spring is arranged inside the cross groove.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-4 , the utility model provides a technical solution:

[0020] A graphite part grinding device with good fixing effect includes a fixed table 1, a gantry stand 2 is provided on the outside of the fixed table 1, a vacuum suction cup body 3 is provided on the top of the fixed table 1, a graphite part body 4 is provided on the top of the vacuum suction cup body 3, a cross groove 5 is opened on the top surface of the fixed table 1, a vacuum pump body 6 is slidably connected to the inner side of the cross groove 5, a traction rope 13 is fixedly connected to the side of the vacuum pump body 6 close to the center of the cross groove 5, a servo motor 10 is fixedly installed at the center of the cross groove 5, the output end of the servo motor 10 is fixedly connected to the center turntable 11, the top four corners of the center turntable 11 are respectively fixedly connected to winding columns 12, an ear plate 14 is fixedly connected to the outside of the fixed table 1, and the bottom end of the ear plate 14 is fixedly connected to a column 15.

[0021] like Figure 1 As shown, a telescopic rod 17 is fixedly installed at the horizontal end of the gantry frame 2, and a dust cover 18 is fixedly connected to the end of the telescopic rod 17. There are two telescopic rods 17 in total. When a group of telescopic rods 17 starts to operate, the up and down lifting action it can achieve will facilitate the device to adjust the height of the grinding turntable body 16 accordingly; a DC motor 19 is fixedly installed at the middle position of the top of the dust cover 18, and the output end of the DC motor 19 passes through the dust cover 18 and is fixedly connected to the grinding turntable body 16. The grinding turntable body 16 and the graphite part body 4 are relatively arranged in the upper and lower positions. When the device realizes the grinding processing operation by rotating the grinding turntable body 16, the dust cover 18 will play a certain dust-blocking auxiliary role from the outside of the grinding turntable body 16.

[0022] like Figure 1 、 Figure 2 . Figure 3 and Figure 4 As shown, the vacuum pump body 6 is fixedly connected to a first limiting vertical plate 7 on one side away from the center position of the cross groove 5, and the first limiting vertical plate 7 is fixedly connected to a spring 8 on one side away from the vacuum pump body 6. The spring 8 is fixedly connected to a second limiting vertical plate 9 on one side away from the first limiting vertical plate 7. The first limiting vertical plate 7 and the cross groove 5 are slidingly connected, and the cross groove 5 and the second limiting vertical plate 9 are fixedly connected. The spring 8 is arranged inside the cross groove 5. When a single vacuum pump body 6 is pulled and stretched toward the center position of the cross groove 5, the spring 8 will The top of the ear plate 14 and the top of the winding column 12 are on the same horizontal line, the winding column 12 and the traction rope 13 are wound and connected, the column 15 and the ear plate 14 are vertically arranged, and the vacuum suction cup body 3 and the vacuum pump body 6 are connected by an air pipe. The vacuum suction cup body 3 is distributed in a circular array structure along the center point of the cross groove 5. When the device winds and pulls the traction rope 13 through the winding column 12, the setting of the column 15 and the ear plate 14 will have a guiding and limiting effect on the winding start of the traction rope 13.

[0023] Working process: The electric energy required for the startup and operation of the device in the present invention all comes from an external power supply, and an external PID controller can be connected before the servo motor 10 is started. When the graphite part grinding device with good fixing effect is needed, the graphite part body 4 to be processed is placed flat on the upper position of the fixed table 1, and is adsorbed and fixed by the negative pressure suction force generated after the four vacuum suction cup bodies 3 are started and operated. First, under the limiting effect of the gantry stand 2, the device will control a set of telescopic rods 17 with the dust cover 18 and the grinding turntable body 16 to stretch downward. While ensuring that the bottom surface of the grinding turntable body 16 is in contact with the top of the graphite part body 4, the device starts the DC motor 19 to drive the grinding turntable body 16 to rotate, thereby realizing the surface grinding of the graphite part body 4. When the suction cup assembly of the grinding device is used for the graphite part body 4 that is smaller in size, Before the workpiece is adsorbed and fixed, the specific size information of the workpiece is measured first. Then, the device starts the servo motor 10 to drive the center turntable 11 and the two sets of winding columns 12 above it to rotate according to a preset number of revolutions. At the same time, the winding column 12 can reel in the traction rope 13 under the guidance and limitation of the ear plate 14 and the column 15, so that the four traction ropes 13 can simultaneously pull and drag the two sets of vacuum pump bodies 6 toward the center point of the cross groove 5, and also enable the two sets of suction cup assemblies composed of the vacuum suction cup body 3 and the vacuum pump body 6 to achieve synchronous stretching operation, thereby relatively narrowing the fixing range of the device so that the entire device can adapt to the workpiece with smaller size for adsorption and fixing operation, and avoid incomplete coverage of the suction cup assembly by the workpiece, which causes dust to clog the suction hole when the device is running.
