The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention; all other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, 2, 3, and 4, in this embodiment, an adaptive full-automatic screwing and tapping mechanism includes: the device comprises a seat plate 1, a ball screw 2, a clutch differential group 3 assembled by matching the ball screw 2 and an output bit 4; a slide rail group 11 is arranged at the tail part of the seat plate 1 towards the mechanism output direction, and a slide block of the slide rail group 11 is provided with a servo motor 5 through a motor base; the clutch differential group 3 is fixedly arranged in the middle of the seat plate 1 through a springboard 12; a screw rod mounting port of the clutch differential group 3 is aligned with a power shaft of the servo motor 5; the tail end of the ball screw 2 is butted with a power shaft coupler of the servo motor 5 after being assembled into the clutch differential group 3, and a driver 6 is fixedly sleeved at the front end of the ball screw 2; an output batch head 4 is fixedly arranged on an output shaft ring of the driver 6.
The clutch differential group 3 comprises an assembly cover 31, a screw nut 34 and a clutch friction plate 35; the assembling cover 31 is arranged on the springboard 12 through a bolt frame, and the cavity of the assembling cover 31 faces the springboard 12; a spring 33 is arranged in the cavity of the assembling cover 31, a plane bearing 32 is additionally arranged at the elastic force action end of the spring 33, a screw nut 34 is sleeved on the through hole of the springboard 12, and the end surface of the screw nut abuts against the plane bearing 32; a clutch friction plate 35 is additionally arranged between the springboard 12 and the extension ring of the screw nut 34.
Preferably, the output bit 4 is a bit for screwing a screw or a tap bit for tapping a screw hole, and the driver 6 is a one-way bearing or a fixed coupler; when the mechanism is used for screwing the screw, the single bearing and the screw driver head are assembled, and when the mechanism is used for tapping, the coupler and the screw driver head are assembled and fixed.
Preferably, a second springboard 13 is installed at the head end of the seat board 1, a bearing hole is formed in the position of the alignment output bit 4 on the second springboard 13, a second bearing is additionally installed in the bearing hole, and the output bit 4 penetrates through a shaft hole in which the second bearing is installed.
The following will describe the operation process of the present embodiment in detail with reference to fig. 1 to 4, taking screwing as an example: when the output bit 4 picks up (magnetically attracts) the screw and aligns, the servo motor 5 works to drive the ball screw 2 and the output bit 4 to rotate, and the springboard 12 provided with the screw nut 34 is fixed and the servo motor 5 is arranged through a slide rail, namely, the servo motor 5 can be axially pushed while rotating forwards, namely, the workpiece screw is screwed in along with the ball screw 2; in the process: the single-turn pitch of the ball screw 2 is greater than that of the workpiece screw, so that the stroke of the ball screw 2 is greater than that of the screw, and therefore, the clutch differential group 3 is designed to compensate the difference of the pitch, and the following steps are provided: the single-turn pitch of the ball screw 2 is 10mm, the single-turn pitch of the screw is 1mm, when the ball screw 2 drives the output screwdriver head 4 to rotate and screw the screw, the screw nut 34 is lifted and pressed by the spring 33 and extends to separate from the clutch friction plate 35 at the same time when the screw is screwed into the material, so that the ball screw 2 is axially pushed according to the screw pitch, and the screw nut 34 is in a semi-slip (semi-linkage) state in the process; when the screw is screwed down, the servo motor 5 receives a set torsion value and then reverses the lifting mechanism body, and at the moment, the output bit 4 cannot rotate along with the ball screw 2 due to the driver 6 (a single bearing); the equipment completes one process.
According to the self-adaptive full-automatic screwing and tapping mechanism, the clutch differential group is designed to make up the single-ring pitch difference between the ball screw and a workpiece screw (the ball screw and a tap bit), so that a single bearing is assembled during screwing, the screw bit cannot be taken out when the screw bit is reversely rotated and retreated, and a coupler and the tap bit are assembled and fixed during tapping; the structural design makes it only need a servo motor just can accomplish the process of twisting screw or tapping, has reduced because the power original paper is too much and the fault rate that produces.
