Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.
Examples
The embodiment of the application discloses quick grinding clamping tool of guide pillar.
As shown in fig. 1, 2 and 3, a guide pillar rapid grinding and clamping jig includes: a clamping body 1 in a circular ring shape;
the embedding opening 11 is formed in the clamping body 1 and matched with the end of the guide pillar;
the clamping device comprises a mounting groove 12 and two threaded holes 13, wherein the mounting groove 12 and the two threaded holes 13 are arranged on the side wall of the clamping body 1 in a penetrating manner and are communicated with the embedding opening 11, each threaded hole 13 is connected with a propping component 2, and the mounting groove 12 is rotatably provided with a toggle locking component 3 for locking the end of a guide pillar;
the shifting and locking assembly 3 comprises a rotating shaft 31 which is arranged on the clamping body 1 and vertically penetrates through the mounting groove 12, a shifting rod 32 which is rotatably arranged on the rotating shaft 31 and one end of which is matched with a driving shaft of the machine tool, and the other end of the shifting rod 32 extends into the embedding opening 11 and abuts against the end of the guide pillar after rotating. Through setting up toggle locking subassembly 3 and supporting tight subassembly 2, during the use, insert the guide pillar end in the rabbet 11, rotatory tight subassembly 2 that supports makes the both sides of guide pillar end supported tightly, and at this moment, the lathe drives the axle and stirs driving lever 32 rotatory, and driving lever 32 uses rotation axis 31 as the rotation of axes, and driving lever 32 is far away from the one end rotation of lathe drive shaft and supports tight guide pillar end for the trilateral atress of guide pillar end is stabilized the centre gripping. After clamping is completed, the guide pillar can be ground at one time without clamping and grinding for multiple times, so that the grinding efficiency is improved, and the problem that the surface of the guide pillar is possibly damaged in the clamping process is solved.
The lever 32 is divided into a rotating portion 321 and an extending portion 322, and the rotating portion 321 is elliptical. In the default state, the side of the rotating portion 321 with the shortest distance from the center of the rotating portion 321 is disposed toward the end of the guide post, and when the rotating portion 321 rotates, the elliptical rotating portion 321 gradually abuts against the end of the guide post until completely abutting. The tight power of supporting to the guide pillar end increases gradually in rotatory process, can effectively promote the tight effect of supporting to the guide pillar end.
The extending portion 322 extends arcuately in a direction away from the rotating portion 321, and a first inclined surface 3221 and a second inclined surface 3222 are cut at an end of the extending portion 322. By providing the first inclined plane 3221 and the second inclined plane 3222, when the end of the guide post needs to be locked, a force can be applied to the first inclined plane 3221, and when the end of the guide post needs to be released, a force can be applied to the second inclined plane 3222, so that the force points of releasing and locking are separated, and the force can be better transmitted to the extension portion 322.
The reset assembly 4 comprises a locking buckle 41 arranged on the side wall of the clamping body 1, a locking hole 42 vertically penetrating through the shift lever 32, and a reset spring 43 with one end hung in the locking hole 42 and the other end hung in the locking buckle 41. Through the arrangement of the reset assembly 4, when the end of the guide pillar needs to be loosened, the reset spring 43 pulls the shifting rod 32 to rotate to complete reset, so that the guide pillar is convenient to take down. Meanwhile, the shifting lever 32 after automatic reset can prevent the shifting lever 32 from blocking the installation of the next guide pillar, and the effect of facilitating the installation of the next guide pillar is achieved.
The locking buckle 41 is arched, and two ends of the locking buckle 41 are connected with the side wall of the clamping body 1. The arched locking buckle 41 is firmly fixed on the side wall of the clamping body 1, and the middle part of the locking buckle 41 is used for hanging and buckling the hook of the reset spring 43, so that the reset spring 43 is not easy to break away when being stretched.
The abutting component 2 is a screw 21 in threaded connection with the threaded hole 13 and a pretightening nut 22 arranged on the screw 21 and abutted against the side wall of the clamping body 1. The screw 21 can slide along the threaded hole 13 by rotating the screw 21, so that the end of the guide pillar is abutted tightly, and the sliding in the locking process is prevented. The pretension nut 22 can strengthen the connection stability of the screw 21 and the threaded hole 13 and prevent loosening.
The working principle is as follows: through setting up dial-buckle locking Assembly 3 and supporting tight subassembly 2, during the use, insert the guide pillar end in the rabbet 11, rotatory screw rod 21 can make screw rod 21 slide along screw hole 13 to support the guide pillar end tightly, prevent that the locking in-process from appearing sliding, at this moment, the lathe drives the axle and stirs driving lever 32 rotatory, driving lever 32 uses rotation axis 31 to rotate as the axle, driving lever 32's rotation portion 321 is oval-shaped, support tight guide pillar end during rotatory gradually, make the trilateral atress of guide pillar end, by stable centre gripping. And grinding the guide pillar once after clamping.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
