Detailed Description
The embodiment of the utility model discloses gear grinding machine pinch roller that takes precautions against earthquakes.
Referring to fig. 1, the method includes:
the top of the bottom plate 1 is fixedly connected with a sleeve 101, the top of the sleeve 101 is rotatably connected with a nut seat 102, and the inner wall of the nut seat 102 is in threaded connection with a threaded rod 103;
one end of the rocker arm 2 is sleeved on the outer surface of the top end of the threaded rod 103, the rocker arm 2 is rotatably connected with the top end of the threaded rod 103, a limiting assembly is arranged between the rocker arm 2 and the top end of the threaded rod 103, the other end of the rocker arm 2 is fixedly connected with a pinch roller rod 201, and the bottom end of the pinch roller rod 201 is rotatably connected with a bearing 202;
the threaded rod 103 moves downwards relative to the nut seat 102, the pressure wheel rod 201 is driven to move up and down through the rocker arm 2 until the bearing 202 at the bottom end of the pressure wheel rod 201 abuts against the saw blade, and then the gear grinding is carried out, so that the saw blade of the gear grinding machine does not vibrate in the gear grinding process due to the fact that the bearing 202 abuts against the saw blade.
The bottom end of the threaded rod 103 extends downward through the nut seat 102 and is inserted into the interior of the sleeve 101, and the outer surface of the threaded rod 103 does not contact the inner wall of the sleeve 101.
The mounting hole that link up from top to bottom is all seted up to the four corners department of bottom plate 1, and all is provided with the bolt on the inner wall of mounting hole.
Referring to fig. 2, the limiting assembly includes a fixing block 3, the fixing block 3 is fixedly connected to the outer surface of the end portion of the rocker arm 2, the fixing block 3 is provided with a threaded hole penetrating from left to right, and the inner wall of the threaded hole is in threaded connection with a positioning bolt 301.
The end part of the positioning bolt 301 sequentially penetrates through the outer walls of the fixed block 3 and the rocker arm 2 and is tightly attached to the outer surface of the top end of the threaded rod 103;
through the spacing subassembly that sets up, rotate positioning bolt 301 for positioning bolt 301 breaks away from with the top of threaded rod 103, can rotate rocking arm 2 and pinch roller pole 201 this moment, until make pinch roller pole 201 be in directly over saw bit axle center department, then the dead-beat positioning bolt 301 for positioning bolt 301 offsets with the top of threaded rod 103, then rocking arm 2 can't rotate, and then makes pinch roller pole 201 can't rotate.
The working principle is as follows: in the using process, firstly, the bottom plate 1 is fixed on a rack of a gear grinding machine through four bolts on the bottom plate 1, when gear grinding is needed, the nut seat 102 is firstly rotated, the nut seat 102 is connected to the top of the sleeve 101 in a rotating mode, so that the nut seat 102 rotates relative to the sleeve 101, and the inner wall of the nut seat 102 is connected with the threaded rod 103 in a threaded mode, so that the threaded rod 103 moves upwards relative to the nut seat 102, and the pinch roller rod 201 is driven to move upwards through the rocker arm 2;
then, the positioning bolt 301 is rotated to enable the positioning bolt 301 to be separated from the top end of the threaded rod 103, at this time, the rocker arm 2 and the pinch roller rod 201 can be rotated until the pinch roller rod 201 is positioned right above the axis of the saw blade, then the positioning bolt 301 is rotated reversely, so that the positioning bolt 301 is abutted against the top end of the threaded rod 103, the rocker arm 2 cannot be rotated, and the pinch roller rod 201 cannot be rotated;
finally, the nut seat 102 is rotated reversely, so that the threaded rod 103 moves downwards relative to the nut seat 102, the pinch roller rod 201 is driven to move upwards and downwards through the rocker arm 2 until the bearing 202 at the bottom end of the pinch roller rod 201 abuts against the saw blade, and then the gear grinding is carried out, and the saw blade of the gear grinding machine does not vibrate in the gear grinding process because the bearing 202 abuts against the saw blade;
after the gear grinding is finished, the actions are repeated, and the rocker arm 2 and the pinch roller rod 201 are moved to the initial positions.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
