Technical Field

[0001] This utility model relates to the technical field of flat grinding equipment, specifically a flat grinding equipment with automatic lifting air pressure assistance. Background Technology

[0002] A surface grinder is a device that uses mechanical grinding to smooth the surface of materials. It grinds the contact surface between the flat material and the grinding disc. The core functions of a surface grinder include removing the surface layer, optimizing flatness, and improving the efficiency of subsequent processing.

[0003] In existing surface grinding machines, the material is placed on the grinding table and then pressed by individual pressing structures until all the material is stable before surface grinding. Before processing, the material needs to be positioned in multiple locations, which takes a long time and results in poor positioning effect, thus affecting the processing efficiency and the utilization efficiency of the surface grinding equipment. This needs to be optimized and improved. Utility Model Content

[0025] Specifically, such as Figure 1 As shown, the outer side of the positioning disk 3 is connected to a limit block 4. There are three limit blocks 4. The limit blocks 4 are used to limit the placement position of the positioning disk 3, so that the grinding disc 2 can perform flat grinding on the product placed at the bottom of the positioning disk 3.

[0026] An auxiliary pressing component is provided at the top of the grinding disc 2. The auxiliary pressing component includes a placement plate 6, and a telescopic cylinder 7 is connected to the inner side of the placement plate 6. A counterweight block 15 is connected to the bottom end of the telescopic cylinder 7. The auxiliary pressing component is used for auxiliary pressing of the positioning disc 3.

[0027] Specifically, such as Figure 2 As shown, a support rod 5 is fixedly connected to the outer side of the top of the grinding disc 2, and a placement plate 6 is fixedly installed on the top of the support rod 5. The support rod 5 is used to support the placement plate 6. A handle switch 9 is fixedly installed on the outer side of the placement plate 6. The handle switch 9 controls the switch of the telescopic cylinder 7, which controls the position of the counterweight 15 to be close to the positioning disc 3.

[0028] Specifically, such as Figure 2 As shown, a pressing connecting plate 10 is fixedly installed at the bottom of the telescopic cylinder 7, and an elastic connecting rod 8 is fixedly connected to the outer side of the top of the pressing connecting plate 10. The telescopic cylinder 7 controls the lifting and lowering of the pressing connecting plate 10, and the elastic connecting rod 8 is used to improve the stability of the pressing connecting plate 10 when it moves.

[0029] Specifically, such as Figure 3As shown, a first chain link 11 is fixedly connected to the bottom end of the lower connecting plate 10, and a second chain link 13 is connected to the bottom end of the first chain link 11. A screw 14 is inserted through the inner side of the second chain link 13, and a detachable nut 12 is connected to the top end of the screw 14. The first chain link 11 and the second chain link 13 are fitted together, and then the screw 14 passes through the hole between the second chain link 13 and the first chain link 11 and is locked by connecting the detachable nut 12. There are three such combinations.

[0030] The bottom end of the counterweight 15 is provided with a bonding buffer assembly, which includes an elastic connector 17 and a bonding pressure plate 18 connected to the bottom end of the elastic connector 17. The bonding buffer assembly is used for bonding buffer protection of the positioning disk 3.

[0031] Specifically, such as Figure 4 As shown, the counterweight 15 is fixedly connected to the bottom end of the chain link 13, the elastic connector 17 is fixedly connected to the inner bottom wall of the counterweight 15, the pressure plate 18 is slidably connected to the inner bottom end of the counterweight 15, and the upper and lower ends of the elastic connector 17 are fixedly connected to the inner bottom wall of the counterweight 15 and the top end of the pressure plate 18.

[0032] Specifically, such as Figure 4 As shown, the inner side of the counterweight 15 is provided with an adjustment groove 16 that is slidably connected to the bonding pressure plate 18. The bonding pressure plate 18 slides along the adjustment groove 16 on the inner side of the counterweight 15 to facilitate the adjustment of the buffer position.

[0033] In this embodiment: a telescopic cylinder 7 is set to adjust the height of the bottom pressing connecting plate 10. The bottom of the pressing connecting plate 10 is provided with three sets of chain links 11 and 13 for connection, so that the counterweight 15 contacts the positioning plate 3 for synchronous pressing, and performs counterweight compression. The pressure is relatively uniform, which improves the flat grinding effect. When the counterweight 15 descends to press the positioning plate 3, the contact part is bonded by the bonding pressure plate 18. The bonding pressure plate 18 is slidably connected to the counterweight 15, and the connection part is elastically connected by the elastic connector 17, which has a certain buffering effect.

[0034] The specific solution is as follows: When the material to be processed is being ground, it is first placed inside the positioning plate 3. Then, the surface of the product to be ground is placed against the grinding plate 2. Before processing, a telescopic cylinder 7 is set to adjust the height of the bottom pressing connecting plate 10. The bottom of the pressing connecting plate 10 is equipped with three sets of chain links 11 and 13 for connection, so that the counterweight 15 contacts the positioning plate 3 and presses synchronously, so that the top of the material to be processed has a certain pressure. Then, a limit stop 4 is set on the side to restrict the position of the positioning plate 3, thereby improving the grinding effect. When the counterweight 15 descends to press the positioning plate 3, the contact part is bonded by the bonding pressure plate 18. The bonding pressure plate 18 and the counterweight 15 are slidably connected, and the connection part is elastically connected by the elastic connector 17, which has a certain buffering effect, so that the counterweight does not directly collide, thereby improving the protective performance and extending the service life of the equipment.
