Detailed Description

As shown in fig. 1 to 6, an adjustable chamfering tool comprises a base 1 and a connecting cushion block 3, wherein a support column 2 is fixedly arranged on the base 1; the connecting cushion block 3 is fixedly arranged on the supporting column 2, and the connecting cushion block 3 is provided with a clamping mechanism 8; the clamping mechanism 8 comprises a center block 4, at least two abutting portions 5 are arranged around the center block 4, a threaded pipe 41 is transversely and fixedly arranged on the center block 4, a threaded rod 42 is connected with the threaded pipe 41 in a threaded mode, the abutting portions 5 are sleeved at the front end of the threaded rod 42, a plurality of abutting portions 5 are included to be round, and the abutting portions 5 are used for abutting against the inner diameter of the locking gear 9.

By adopting the technical scheme, according to the type of the gear 9 to be processed, the distance between the threaded rod 42 and the threaded pipe 41 is adjusted, the threaded rod 42 is sleeved with the abutting portion 5, and the outer diameter enclosed by the abutting portion 5 is ensured to be matched with the inner diameter of the gear 9. The clamping mechanism 8 is used for clamping the gear 9, and the connecting cushion block 3 plays a certain bearing role, but does not contact with the tooth groove part, so that the chamfering process of the upper end face and the lower end face of the gear 9 can be simultaneously realized.

As a preferred scheme, the abutting portion 5 includes an upper abutting block 51 and a lower abutting block 52, the lower abutting block 52 is sleeved at the front end of the threaded rod 42, an expansion rubber layer 7 is sandwiched between the upper abutting block 51 and the lower abutting block 52, a compression rod 61 is arranged between the upper abutting block 51 and the lower abutting block 52 in a penetrating manner, and the compression rod 61 is in threaded connection with the lower abutting block 52. Because the screw holes 43 are formed in the upper abutting block 51 and the lower abutting block 52, the compression rod 61 is in threaded connection with the upper abutting block 51 and the lower abutting block 52, so that the compression rod 61 presses down the upper abutting block 51, the expansion rubber layer 7 is expanded outwards after being extruded by the upper abutting block 51, and the function of resisting rotation is achieved on the inner wall of the gear 9.

As a preferable scheme, the abutting portion 5 comprises an upper abutting block 51 and a lower abutting block 52, the upper abutting block 51 is sleeved at the front end of the threaded rod 42, an expansion rubber layer 7 is clamped between the upper abutting block 51 and the lower abutting block 52, a pressing rod 61 is arranged between the upper abutting block 51 and the lower abutting block 52 in a penetrating mode, and the pressing rod 61 is in threaded connection with the lower abutting block 52. Because the screw holes 43 are formed in the upper abutting block 51 and the lower abutting block 52, the compression rod 61 is in threaded connection with the upper abutting block 51 and the lower abutting block 52, so that the compression rod 61 compresses the lower abutting block 52 towards the upper abutting block 51, and the expansion rubber layer 7 expands outwards after being compressed, and plays a role in abutting and stopping rotation on the inner wall of the gear 9.

Preferably, a handle 62 is fixedly arranged on the pressing rod 61. The handle 62 is more labor-saving in design, and is convenient for rotating the compression bar 61 to press the expansion rubber layer 7 downwards.

Preferably, the central block 4 is in a regular triangle shape, the number of the interference parts 5 is three, and each interference part is internally sleeved with two threaded rods 42.

After the processing is finished, the gear 9 can be taken down by only rotating the handle 62 to loosen the expansion rubber layer 7, the gear 9 is repeatedly put in, and batch processing can be finished by continuously rotating the handle 62 to compress. The design of the connecting pad 3 at this time ensures that it is smaller than the outer diameter of the model minimum gear 9 to be machined.

When the inner diameter of the gear 9 is larger than the outer diameter of the connecting cushion block 3, as shown in fig. 5, the distance between the threaded rod 42 and the threaded pipe 41 is adjusted according to the model of the batch of gears 9 to be processed, the threaded rod 42 is sleeved with the abutting portions 5, the outer diameter enclosed by the three abutting portions 5 is ensured to be matched with the inner diameter of the gear 9, the outer diameter of the connecting cushion block 3 is detected due to the inner diameter of the gear 9, when the gear 9 is installed, the gear 9 is required to be manually supported, the expansion rubber layer 7 is waited to be abutted tightly, so that the gear 9 can be polished by a loose hand after being clamped, and the rest steps are the same.
