Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

In the prior art, when the internal tooth of the annular gear is cut, as the blocking influence on the movement of the cutter is considered, the adopted fixing component cannot be arranged on the inner side of the round billet or on the upper end face side of the round billet when the round billet is fixed on the processing table 2, and therefore, the fixing component such as a multi-claw chuck structure can only be adopted, so that the outer peripheral side of the round billet is in interference fixation, the defect of the mode is that the structural deformation of the round billet is easily caused, the cutting precision is influenced, and the application can effectively improve the point, and particularly refers to the following embodiments:

as shown in fig. 1 to 6, the gear ring machining tool according to one embodiment of the present application is based on a base 1 and a machining table 2 rotatably disposed on the base 1 in the prior art, and the power mechanism for driving the machining table 2 to rotate is disposed on the base, and based on these, the present application further includes the following parts:

a bracket 3 provided on the base 1, the vertical position of the bracket 3 on the base 1 being set to be adjustable;

the pressing block 4 is rotatably arranged on the bracket 3, is provided with a circumferential surface 5 coaxial with the rotation axis of the pressing block and is used for pressing and holding the upper end surface of the round blank;

in this case, the axis of rotation of the holding-down block 4 on the support 3 is perpendicular to the axis of rotation of the processing table 2 on the base 1;

based on the above characteristics, refer to fig. 6, during operation place the round billet on processing platform 2, after adjusting the round billet position and making its axis unanimous with processing platform 2 axis of rotation, at adjusting bracket 3, thereby make the support 3 move down, thereby make the circumference 5 on the pressure hold piece 4 conflict on the round billet up end, specifically, the support 3 is a plurality of with the specific quantity of the whole combination of pressure hold piece 4, and distribute in the horizontal circumference side of round billet, at this moment, the pressure hold piece 4 cooperates processing platform 2 to form the centre gripping to the round billet, thereby fix the round billet on processing platform 2, at this moment when processing platform 2 rotates, because friction drives, the round billet can rotate simultaneously, thereby cooperate the cutter to cut, this in-process, the pressure hold piece 4 is because the rotation sets up, and the axis is mutually perpendicular with the axis of rotation of processing platform 2, so the pressure hold piece 4 rotates simultaneously, thereby can not influence the rotation of round billet, and play the pressure hold to accomplish the fixed action to the round billet, and the whole in-process, the position of pressure hold piece 4 keeps motionless, at this moment, the position of pressure hold round billet 4 to the horizontal side of round billet, even when stretching into the horizontal side of the round billet, the horizontal direction is not influenced by the side of the round billet is avoided, the side of the round billet is not influenced by the side of the grinding, the round billet is cut, the side of the round billet is not influenced by the side when the side is moved, the side of the round billet is moved, and the side is not influenced by the side of the round billet is completely.

As shown in fig. 1-3, in some embodiments, the whole device may further include a plurality of abutting blocks 6 disposed on the processing table 2, which are located on the same circumferential surface 5, and when the round blank is placed, the plurality of abutting blocks 6 may be located on the circumferential side of the round blank, where the axis of the round blank is approximately consistent with the rotation axis of the processing table 2, so that the plurality of abutting blocks 6 may play an auxiliary alignment role when the round blank is placed, so that only fine adjustment needs to be performed on the position of the round blank after the round blank is placed, and then the bracket 3 may be moved down, so as to fix the round blank.

In some embodiments, regarding the abutment 6, the distance between the abutment 6 and the rotation axis of the processing table 2 can be set to be adjustable, so that when round blanks with different diameters need to be cut, the position of the abutment 6 can be finely adjusted, and the alignment of the round blanks with different sizes can be better matched for placement.

As shown in fig. 1 to 4, in some embodiments, the abutment 6 is configured with a post 7 slidably matched with the processing table 2, and a rotating post 8 in threaded fit with the processing table 2 is rotatably disposed on the abutment 6, so that the above effect of adjusting the position of the abutment 6 on the processing table 2 can be achieved when the rotating post 8 is rotated.
