Detailed Description
The utility model is further described with reference to the following description of the drawings.
As shown in fig. 1-2, a tool bit side-mounting locking mechanism comprises a tool bit 1, a tool bit 2, a tool bit blind rivet 3, a claw 4, a stud 5 and a driving pin 6, wherein a positioning short cone 1.1 is arranged on the tool bit 1, the tool bit 2 is provided with a positioning taper hole, the tool bit 1 is connected with the tool bit 2 by adopting the positioning short cone 1.1 and is limited, a threaded hole 1.2 is formed in the positioning short cone 1.1, one end of the tool bit 2 is provided with the tool bit blind rivet 3, and the positioning short cone 1.1 on the tool bit 1 is in threaded connection with the tool bit blind rivet 3.
In the technical scheme, a self-locking wedge surface 3.1 and a groove bevel edge 3.2 are arranged on the tool bit blind rivet 3.
In the technical scheme, a jaw groove is formed in a cutter bar 2, a jaw 4 is arranged in the jaw groove, the jaw 4 comprises a positive thread jaw 4.1 and a negative thread jaw 4.2, and the positive thread jaw 4.1 and the negative thread jaw 4.2 are matched with a groove bevel edge 3.2 on a cutter head blind rivet 3.
In the technical scheme, a positive thread claw 4.1 and a negative thread claw 4.2 are connected with a cutter bar 2 through a double-head screw 5 bolt.
In the technical scheme, external threads corresponding to the positive thread clamping jaw 4.1 and the negative thread clamping jaw 4.2 in the rotation direction are arranged at two ends of the stud bolt 5.
In the technical scheme, at least two pin holes are formed in the tool bit 1 and the tool bar 2, driving pins 6 are arranged in the pin holes, and torque required in machining can be transmitted through positioning and driving of the driving pins 6.
In this technical scheme, through right-handed stud 5, the positive screw jack catch 4.1 and the reverse screw jack catch 4.2 of both sides remove to cutter arbor 2's jack catch groove center simultaneously, block cutter head blind rivet 3's auto-lock wedge face 3.1, drive cutter head blind rivet 3 to cutter arbor 2 direction axial displacement to drive cutter head 1 to cutter arbor 2 direction axial displacement reaches the effect of taut cutter head 1. The self-locking wedge surface 3.1 of the tool bit blind rivet 3 is provided with a self-locking angle, and under the action of the positive pressure of the screwing of the stud 5, a self-locking moment is generated to prevent the clamping jaw 4 from loosening, so that the tool bit 1 is prevented from loosening and separating from the tool bar 2.
