Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a grinder convenient for chip removal. Background Art

[0002] A grinder is a commonly used device for grinding various tools and cutters, and is also used for grinding, deburring and cleaning of ordinary small parts. During the grinding process, chips will be generated. Therefore, chip removal of the grinder is particularly important. After retrieval, a Chinese patent with the publication number CN220388992U discloses a grinder convenient for chip removal, which includes a base, a machine body fixedly installed on the base, and grinding wheels drivingly installed at both ends of the machine body. A protective cover is arranged outside the grinding wheels. A chip removal assembly is arranged on the base. The chip removal assembly includes a collection box fixedly installed on the base and a chip suction cover fixedly installed on the machine body. Both ends of the chip suction cover are respectively arranged towards the two grinding wheels. A chip suction pipe is connected between the collection box and the chip suction cover. A suction fan is fixedly installed on one side of the collection box. A support assembly is arranged below the grinding wheels at the top of the base; through the arrangement of the chip removal assembly, during grinding, when starting the grinding, the suction fan can be started to suck the generated waste chips into the chip suction cover. The waste chips enter the collection box through the chip suction pipe and fall into the drawer. After the work is completed, the drawer can be pulled out for cleaning, so as to reduce the scattering of waste chips everywhere and facilitate the treatment of waste chips. However, its grinding and chip removal require two driving structures. Therefore, while the cost investment is high, the structural volume and weight also increase accordingly. And the chips have an external path before entering the chip suction cover. At the same time, the chip suction range of the chip suction cover is relatively wide. Therefore, other surrounding objects are easily sucked in while sucking the chips. Therefore, the chip suction burden is increased. Therefore, a grinder convenient for chip removal is designed, which can adopt a set of driving mechanisms to drive the grinding wheel grinding mechanism and the chip suction mechanism to operate, and at the same time, the chip suction port of the chip suction mechanism is arranged at the grinding position of the grinding wheel grinding mechanism, and the chips can be directly sucked into the grinding mechanism and enter the chip suction mechanism after the grinding wheel grinding mechanism finishes grinding, so as to improve the chip suction efficiency and reduce the chip suction burden.

[0021] Embodiment:

[0022] Please refer to Figures 1-4, A grinding wheel machine convenient for chip removal, including an operating table 1. Above the operating table 1, a grinding wheel grinding mechanism, a chip suction mechanism, and a driving mechanism are sequentially arranged. The chip suction mechanism includes a diversion ring box 3 fixedly installed on the operating table 1. An exhaust port is opened at the top of the diversion ring box 3, and a filter screen 8 is arranged at the exhaust port. A chip collection mechanism is arranged at the bottom of the diversion ring box 3. The grinding wheel grinding mechanism includes a grinding cover 5 fixedly communicated with the diversion ring box 3. A downwardly arranged grinding port is opened on the grinding cover 5. A grinding wheel 7 extending out of the grinding port is rotatably connected in the grinding cover 5. A diversion member is arranged in the diversion ring box 3. Both the grinding wheel 7 and the diversion member are fixedly connected to the output end of the driving mechanism. Further, a plurality of through holes 17 are opened on the grinding wheel 7 to facilitate the entry of chips into the diversion ring box 3. Further, a calibration strip 18 is embedded and installed at a position on the operating table 1 below the grinding port to facilitate the horizontal movement of the workpiece to be ground below the grinding wheel 7. Further, the filter screen 8 is fixedly installed at the exhaust port.

[0023] Specifically, a rotating shaft 6 is rotatably connected between the diversion ring box 3 and the grinding cover 5. The output end of the driving mechanism is fixedly connected to one end of the rotating shaft 6. Both the grinding wheel 7 and the diversion member are fixedly installed on the rotating shaft 6. Through the rotating shaft 6, the grinding wheel 7 and the diversion member are connected as a whole, so as to facilitate the simultaneous rotation of the grinding wheel 7 and the driving member by the driving mechanism. Further, the driving mechanism includes a driving motor 2 fixedly installed on the operating table 1. The output end of the driving motor 2 is fixedly connected to the rotating shaft 6 by a flange, which is convenient for disassembling and replacing the driving motor 2.

[0024] Specifically, the diversion member includes a plurality of diversion plates 9 fixedly installed on the rotating shaft 6 in the circumferential direction. And on one side of each of the plurality of diversion plates 9 away from the rotating shaft 6, there is a scraping surface that can contact the filter screen 8. Through the plurality of diversion plates 9, as the rotating shaft 6 rotates, the air on the side of the grinding cover 5 can be induced into the diversion ring box 3 and discharged through the exhaust port. At the same time, the scraping surface on the diversion plate 9 can scrape off the chips adhering to the filter screen 8 when rotating to the side of the filter screen 8, which is convenient for maintaining the filtering ability of the filter screen 8 and the chip suction ability of the chip suction mechanism.

[0025] Specifically, the chip collection mechanism includes a chip collection box 11. A bottom frame 13 is fixedly installed below the operating table 1. The chip collection box 11 is placed on the bottom frame 13. And a chip guide groove 10 with its bottom end flush with the top end of the chip collection box 11 is fixedly communicated with the bottom of the diversion ring box 3. Through the chip guide groove 10, the chips remaining in the diversion ring box 3 can be guided into the chip collection box 11. And the alignment of the chip guide groove 10 and the chip collection box 11 can keep the bottom of the diversion ring box 3 sealed in the chip suction state, so that the gas is concentrated and discharged through the exhaust port at the top.

[0026] Specifically, an outer side of the chip guide groove 10 is provided with a limit ring frame 12 that can fix the chip collection box 11 directly below the chip guide groove 10. Lifting lugs 14 are fixedly installed on both sides of the limit ring frame 12, and a lifting slide column 15 is slidably fitted on the lifting lugs 14. The top end of the lifting slide column 15 is fixedly connected to the bottom end of the operating table 1, and a limit block 16 is fixedly installed at the bottom end of the lifting slide column 15. Through the cooperation of the lifting lugs 14, the lifting slide column 15, and the limit block 16, the limit ring frame 12 can be easily lifted and slid. When the limit ring frame 12 is lifted above the chip collection box 11, the chip collection box 11 can be pulled out from below the chip guide groove 10 for cleaning. After cleaning, the chip collection box 11 can be put back, and then the limit ring frame 12 can be lowered back to the height where it can fix the chip collection box 11.

[0027] Specifically, the diversion ring box 3 is fixedly communicated with the grinding cover 5 through a slag collection ring sleeve 4. Through the slag collection ring sleeve 4, it is convenient to divert the chips sucked in through the grinding cover 5 to the side of the diversion ring box 3.

[0028] During use, the driving mechanism is started to drive the grinding wheel grinding mechanism and the chip suction mechanism to operate simultaneously. The grinding wheel 7 and the diversion member rotate synchronously. Then, the workpiece to be ground is horizontally pushed from the operating table 1 towards the grinding wheel 7 side, thus completing the grinding operation. The generated chips are directly sucked into the grinding cover 5 under the diversion action of the diversion member through the grinding port and then enter the diversion ring box 3, and then are discharged through the exhaust port. The chips are retained in the diversion ring box 3 by the filter screen 8. After grinding and chip suction are completed, the driving mechanism is turned off, and then most of the chips in the diversion ring box 3 fall into the lower chip collection mechanism under the action of their own gravity.
