[0020] The embodiment of the present application provides an electric threading machine toothed disc, which effectively solves the technical problem that the above-mentioned toothed disc is fixed by multiple bolts. When the internal components are damaged, they need to be disassembled and repaired with the help of tools, which is inconvenient for repair and maintenance. When the internal components need to be maintained or replaced, the bolts are loosened to allow the rotating ring to rotate, and then the rotating ring is rotated. The first inclined block fixed on the side end of the rotating ring will apply pressure to the clamping block through the inclined surface. The clamping block will slide inward under the action of the pressure and leave the fixing groove provided on the toothed disc cover. Then the nut is rotated to remove the nut. The toothed disc cover can be removed after losing the constraints of the clamping block and the nut, and the internal components can be maintained. Finally, the chain disc cover is put into the side end of the chain disc shell, and then the rotating ring is rotated. The rotating ring will slide the clamping block out through the first oblique block. After the sliding clamping block is inserted into the fixing groove, the nut and the first oblique block are tightened to complete the fixation of the chain disc cover. The installation and disassembly of the chain disc cover is completed by rotating the rotating ring, which achieves the effect of quick disassembly and easy maintenance. The clamping block fixes the chain disc cover, the first oblique block fixes the clamping block, the rotating ring fixes the first oblique block, and the bolts fix the rotating ring. Through the multi-stage fixing method, the situation in which the bolts fall off due to the vibration of the machine when conventional bolts are used for fixing is avoided, thereby achieving the effect of improving the stability of use.

The overall idea is as follows:

[0023] In view of the problems existing in the prior art, the utility model provides an electric threading machine crankset, comprising a crankset shell 1, a crankset cover 2 is installed on the side end of the crankset shell 1, a rotating ring 4 is rotatably installed on the side end of the crankset shell 1, four clamping blocks 5 are evenly slidably installed on the side end of the crankset shell 1, and four first inclined blocks 12 are evenly fixedly installed on the side end of the rotating ring 4.

[0024] A bolt 11 is threadedly installed on the side end of the rotating ring 4; a guide groove is opened on the side end of the first inclined block 12, a die 6 is slidably installed inside the crankcase shell 1, four fixing grooves 3 are evenly opened on the side end of the crankcase cover 2, and a fixing seat 7 is rotatably installed inside the crankcase shell 1.

[0025] The side end of the fixing seat 7 is evenly fixed with a second inclined block 13, the side end of the fixing seat 7 is fixed with a pull rod 8, the outer wall of the pull rod 8 is threadedly installed with a nut 9, the side end of the crankcase housing 1 is fixed with a limit rod 14, and the side end of the crankcase housing 1 is fixed with a fixing ring 15.

[0026] Principle of the utility model:

[0027] The first step is, when the internal components need maintenance or replacement, loosen the bolt 11 to allow the rotating ring 4 to rotate, and then rotate the rotating ring 4. The first inclined block 12 fixed on the side end of the rotating ring 4 will apply pressure to the block 5 through the inclined surface. The block 5 will slide inward under the action of pressure and leave the fixing groove 3 opened on the chainring cover 2. Then rotate the nut 9 to remove the nut 9. The chainring cover 2 can be removed after losing the constraints of the block 5 and the nut 9. After maintaining the internal components, put the chainring cover 2 into the side end of the chainring shell 1, and then rotate the rotating ring 4. The rotating ring 4 will make the block 5 slide out through the first inclined block 12. After the slid-out block 5 is inserted into the fixing groove 3, the nut 9 and the first inclined block 12 are tightened to complete the fixation of the chainring cover 2. The installation and disassembly of the chainring cover 2 is completed by rotating the rotating ring 4, achieving the effect of quick disassembly and easy maintenance.

[0028] In the second step, the clamping block 5 fixes the chainring cover 2, the first inclined block 12 fixes the clamping block 5, the rotating ring 4 fixes the first inclined block 12, and the bolt 11 fixes the rotating ring 4. The multi-stage fixing method avoids the situation in which the bolts fall off due to the vibration of the machine when fixing with conventional bolts, thereby achieving the effect of improving the stability of use.

[0029] Finally, it should be pointed out that the above embodiments are only representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model should be considered to belong to the protection scope of the present utility model.
