Technical Field

[0001] The utility model relates to the field of pin shaft processing, in particular to an outer circle grinding device for a steel plate pin shaft. Background Art

[0002] The steel plate pin is a component used to connect and fix steel plates or other materials. It is usually made of metal material, with a cylindrical pin head and a threaded pin body. After processing and forming, in order to ensure its roundness, it is necessary to use a rounding device to grind its outer circle to ensure that its roundness reaches the factory standard.

[0003] However, at present, when the existing steel plate pin shaft external cylindrical grinding device is in use, a large amount of debris will be generated when the pin shaft is ground. The lack of better limiting measures will cause the debris to splash and be difficult to collect, and cause impact on the environment. At the same time, the pin shaft surface will absorb the debris in the later stage of grinding, which requires later cleaning, which is more troublesome. Utility Model Content

A filter plate 20 is installed inside the collecting box 7, and an exhaust fan 21 is connected to the bottom of the collecting box 7.

[0028] The exhaust fan 21 exhausts air outwards, so that negative pressure is formed at the notch 8, thereby sucking in the debris generated by grinding.

[0029] The opposite surfaces of the two fixed frames 2 are provided with movable grooves 11, and the inside of the movable grooves 11 is provided with screws 12, and the outside of the movable grooves 11 is provided with chucks 13. The bottom of one of the fixed frames 2 is connected to a limit block 14 adapted to the notch 8, and both sides of the limit block 14 are installed with sliders 1 adapted to the slide groove 1 9. The bottom surface of the other fixed frame 2 is fixedly connected to the top surface of the processing table 1.

[0030] The slide block 1 is arranged to slide in the slide groove 1 9 so that the fixing frame 2 can move laterally, thereby adapting to the fixing of pins of different lengths.

[0031] The rear parts of the two chucks 13 are connected to moving blocks 15, wherein a driving motor 16 is installed inside one of the moving blocks 15, and the driving shaft of the driving motor 16 is fixedly connected to the chuck 13 corresponding to the moving block 15, and a shaft rod 17 is rotatably installed inside the other moving block 15, and one end of the shaft rod 17 is fixedly connected to the chuck 13 corresponding to the moving block 15.

[0032] One of the chucks 13 is driven to rotate by the driving motor 16 , and the other chuck 13 can be driven to rotate by the rotation of the shaft 17 , thereby driving the entire pin shaft to rotate.

[0035] Slide blocks 2 matched with the second slide groove 10 are installed on both sides of one of the fixing frames 2 near the top surface, and the bottom of the connecting plate 3 is fixedly connected to the top surface of the processing table 1.

[0036] A device for grinding the outer circle of a steel plate pin shaft. When in use, first open the movable plate 6, and adjust the distance between the two fixing frames 2 according to the length of the steel plate shaft pin. One of the fixing frames 2 uses a slider 1 to move in a slide groove 1 9 to achieve transverse movement, and then use two chucks 13 to fix the two ends of the pin shaft.

[0037] According to the length of the steel plate pin, a grinding plate 19 of corresponding length is assembled through the connecting rod 18, and then the height of the pin is adjusted. By rotating the screw 12, the moving block 15 is driven to move in the moving groove 11, thereby adjusting the height of the two chucks 13, and then driving the height adjustment of the pin so that the surface of the pin can contact the surface of the grinding plate 19.

The other chuck 13 rotates under the rotation of the shaft 17, thereby driving the entire pin shaft to rotate. The outer wall of the pin shaft is constantly in contact with the surface of the grinding plate 19 for grinding, thereby achieving rounding.

[0039] During grinding, the arc plate 4 is used in conjunction with the connecting plate 3 and the movable plate 6 and the connecting strip 5 to prevent the debris generated by grinding from splashing. The debris generated by grinding falls to the slot 8 and is exhausted outward by the exhaust fan 21, so that negative pressure is formed between the collection box 7 and the slot 8, thereby sucking the generated debris into the collection box 7 and being received and collected by the filter plate 20.

[0040] After grinding, the height of the pin shaft can be lowered, and the negative pressure of the notch 8 can be used to absorb the debris adsorbed on the surface of the pin shaft, thereby achieving the cleaning of the debris on the surface of the pin shaft.
