Firstly, driving a clamping cylinder 12 to move to a position right above a cylinder body 1 positioned in a channel 1801 through a displacement driving mechanism, then, driving two grippers 1202 to be close to the cylinder body 1 continuously by downwards moving the clamping cylinder 12, driving an elastic telescopic piece to be inserted into an inner cavity of the cylinder body 1 from the top of the cylinder body 1 in the downwards moving process to enable the bottom of the elastic telescopic piece to extrude a driving rod 2 (particularly to extrude the bottom of the inner cavity of a lipstick holder 201), driving the elastic telescopic piece to elastically shrink under the action of extrusion force, stopping downwards moving the clamping cylinder 12 after the two grippers 1202 pass over the top of the cylinder body 1 to a specific height, and driving the two grippers 1202 to relatively slide to synchronously extrude the outer side surface of the cylinder body 1 so as to realize clamping and fixing of the cylinder body 1; then the displacement driving mechanism drives the clamping cylinder 12 to drive the cylinder body 1 to move upwards, the bottom of the driving rod 2 is separated from the channel 1801 in the process of moving upwards the cylinder body 1, and at the moment, the elastic force of the elastic telescopic rod is released and pushes the driving rod 2 to slide downwards so that the bottom of the driving rod 2 extends out of the bottom of the cylinder body 1 for a specific length; then the displacement driving mechanism drives the clamping cylinder 12 and the beads to move right above the middle section 3 positioned on the spiral base 4, then the displacement driving mechanism drives the clamping cylinder 12 and the beads to move downwards, so that the bottom of the driving rod 2 continuously moves towards the top of the middle section 3 and presses the top of the middle section 3 (at the moment, if the rod body 202 on the driving rod 2 and the flat hole 301 just correspond to each other, the flat hole 301 is directly inserted into the flat hole 301), the elastic telescopic rod is elastically contracted under the action of the pressing force, after the elastic telescopic rod is elastically contracted to a specific length, the clamping cylinder 12 and the beads stop moving downwards, and the two pushing mechanisms are started to enable the power output ends of the two pushing mechanisms to be close to each other, the two power output ends are continuously close to the middle section 3 until contacting with the middle section 3 and pressing the outer surface of the middle section 3 in the process of the two power output ends, then the middle section 3 is driven to rotate under the action of the friction force, so that the relative rotation is generated between the middle section 3 and the driving rod 2, the flat hole 301 on the middle section 3 always corresponds to the driving rod 2 in a certain angle, and once the elastic telescopic rod is elastically released, and the elastic telescopic rod 2 is elastically released, and the driving rod 2 slides downwards, so that the flat rod 2 is inserted into the flat hole 301 and is inserted into the flat hole (the specific hole 301).
Wherein, the rubber ring 1701 is fixedly adhered in the inner wall of the positioning seat 17, the outer surface of the screw base 4 is pressed with the rubber ring 1701 to generate friction force, and the friction force between the outer surface of the screw base 4 and the rubber ring 1701 is larger than the rotation resistance of the middle section 3, so that the screw base 4 does not rotate when the middle section 3 is driven to rotate by two pushing mechanisms.
According to the invention, through improving the bead feeding device, the elastic telescopic piece can be inserted into the inner cavity of the cylinder body 1 and is abutted against the driving rod 2 in the process of clamping and fixing the cylinder body 1 by the clamping cylinder 12, and because the cylinder body 1 is vertically positioned in the channel 1801 (refer to the prior art), the bottom of the driving rod 2 cannot move downwards after being abutted against the bottom of the channel 1801, and at the moment, the elastic telescopic piece can be elastically contracted to store force when the driving rod 2 is extruded by the elastic telescopic piece based on the limit of the driving rod 2, and when the cylinder body 1 clamped and fixed by the clamping cylinder 12 is moved out of the channel 1801 by the bead feeding device, the driving rod 2 can slide downwards under the elastic force of the elastic telescopic piece so as to push the bottom of the driving rod 2 out of a certain length from the bottom of the cylinder body 1; when the displacement driving mechanism on the bead feeding device moves the cylinder 1 and the driving rod 2 to the position right above the middle section 3 and drives the cylinder 1 downwards, the bottom of the driving rod 2 can be abutted against the top of the middle section 3 (if the driving rod 2 just corresponds to the flat hole 301 on the middle section 3 at this time, the bottom of the driving rod 2 can be directly inserted into the flat hole 301, otherwise, the bottom of the driving rod 2 is abutted against the top of the middle section 3), the elastic telescopic piece is elastically contracted again along with the downward movement of the cylinder 1, so that the driving rod 2 elastically slides upwards to enable the bottom of the driving rod 2 to elastically press the top of the middle section 3, then the cylinder 1 stops to be moved downwards and is fixed at a specific height, and then two pushing mechanisms are started, based on the friction force between the power output ends of the two pushing mechanisms and the middle section 3, the middle section 3 can be pushed to rotate relative to the driving rod 2, no matter what angle the driving rod 2 is positioned in, the flat hole 301 on the middle section 3 always corresponds to the driving rod 2 in a certain angle in the relative rotating process, after the corresponding elastic piece is automatically released, and the flat rod 301 can be automatically pushed down to the flat hole 301 corresponding to the driving rod 2 and automatically inserted into the middle section 2. The operator does not need to observe and provide a special alignment monitoring device in the whole operation process of the driving rod 2 corresponding to the flat hole 301, so that the operation difficulty is greatly reduced; moreover, the elastic telescopic piece, the pushing mechanism and the clamping cylinder 12 are all part of the bead feeding device, and the setting of the coarse positioning device and the fine positioning device in the prior art is canceled through ingenious structural design and integration, so that the integral structure of the assembling machine is simplified. Compared with the prior art, the invention can simplify the structure of the assembly machine, reduce the operation difficulty of the driving rod 2 corresponding to the flat hole 301, and effectively solve the defects in the prior art;
meanwhile, the invention utilizes the elastic telescopic piece, and can drive the driving rod 2 to be automatically inserted into the flat hole 301 after the driving rod 2 corresponds to the flat hole 301, so that the elastic telescopic piece has unexpected technical effect, and the operation of inserting the driving rod 2 into the flat hole 301 in the prior art is omitted.

Specifically, the push plate 6 is a power output end of the pushing mechanism, the damping cylinder 5 provides power output, the push plate 6 can be driven to move by starting the damping cylinder 5, and the two damping cylinders 5 on the two pushing mechanisms are simultaneously started to enable the two push plates 6 to synchronously and relatively move, and the relative movement of the two push plates 6 drives the middle section 3 sleeved on the spiral base 4 to rotate. The damping cylinder 5 is the prior art, can reduce the velocity of movement of push pedal 6 through damping cylinder 5, and then reduce the rotational velocity of well festival 3 to when making flat hole 301 on the well festival 3 correspond with the bottom of actuating lever 2, actuating lever 2 can insert in flat hole 301 steadily.
Further, the pushing plate 6 includes a connecting plate 601 fixedly connected to the output end of the damping cylinder 5, a push-pull plate 603 fixedly connected to the connecting plate 601, and a friction plate 604 elastically slidably mounted on opposite surfaces of the two push-pull plates 603 on the two pushing plates 6, where the opposite surfaces of the two friction plates 604 are elastically press-fitted to front and rear sides of the outer surface of the middle section 3, and the two damping cylinders 5 drive the two friction plates 604 to approach each other to rotate the middle section 3 in a process of driving the two pushing plates 6 to approach each other. Specifically, the opposite surfaces of the two push-pull plates 603 are provided with inner grooves, friction plates 604 are slidably arranged in the inner grooves, a plurality of springs 605 are arranged in the inner grooves, one ends of the springs 605 are fixedly connected with the friction plates 604, the other ends of the springs 605 are fixedly connected with the inner walls of the inner grooves, the two friction plates 604 elastically squeeze the outer surfaces of the middle section 3 under the elastic force of the springs 605, and one half of the friction plates 604 are positioned in the inner grooves, and the other half of the friction plates 604 are protruded out of the inner grooves to squeeze the middle section 3. The friction plates 604 move along with the movement of the push-pull plate 603, and when the two push plates 6 move relatively, the two friction plates 604 are driven to move relatively so as to drive the middle joint 3 to rotate.
Still further, the opposite surfaces of the two friction plates 604 near the end of the middle section 3 are each provided with an outwardly curved arc surface 6041, and the maximum vertical distance between the two arc surfaces 6041 is greater than the diameter of the middle section 3 so that the middle section 3 smoothly enters between the two friction plates 604. And, the vertical distance between the opposite faces of the two friction plates 604 is smaller than the diameter of the middle joint 3 so that the two friction plates 604 can elastically press the middle joint 3.
Still further, the push plate 6 further includes a limiting plate 602 fixedly installed on the connecting plate 601 and diagonally arranged with the push-pull plate 603, and two limiting plates 602 located on the two push plates 6 in one-to-one correspondence are respectively located at front and rear sides of the vertical center line of the driving rod 2 and are in abutting fit with the driving rod 2 located between the cylinder 1 and the middle section 3, and in the process of rotating the pushing middle section 3, where the two friction plates 604 are close to each other, ends of the two limiting plates 602 push the driving rod 2 to rotate so that the driving rod 2 is limited between the two limiting plates 602. Specifically, the two limiting plates 602 correspond to the rod body 202 located between the cylinder 1 and the middle section 3, the vertical distance between the two limiting plates 602 is smaller than the width of the rod body 202, in the process that the two friction plates 604 are close to each other to push the middle section 3 to rotate, the two limiting plates 602 are continuously close to the driving rod 2 until being abutted against the rod body 202 of the driving rod 2 and pushing the driving rod 2 to rotate so as to enable the rod body 202 and then between the two limiting plates 602, after that, the driving rod 2 is limited by the two limiting plates 602 and does not rotate any more, and the middle section 3 continues to rotate, so that relative rotation between the middle section 3 and the driving rod 2 can be ensured, and accordingly, the driving rod 2 can correspond to the flat hole 301.

Further, the length of the limiting plate 602 is smaller than that of the friction plate 604, so that in the process of driving the two pushing plates 6 away from each other by the two damping cylinders 5 in a one-to-one correspondence manner, the two limiting plates 602 and the driving rod 2 are staggered first, then the two friction plates 604 drive the middle section 3 to rotate in a manner of being away from each other, and the rotation of the middle section 3 drives the driving rod 2 penetrating through the flat hole 301 to rotate so as to enable the external thread 203 to be screwed into the internal thread 402. Specifically, after the two push plates 6 move to a specific position in a direction close to each other, the driving rod 2 can be inserted into the screw base 4, and then the two damping cylinders 5 drive the two push plates 6 to move in a direction away from each other, in the first half stroke, the driving rod 2 is limited by the two limiting plates 602 and cannot rotate, so that the middle section 3 cannot rotate, sliding friction is generated between the two friction plates 604 and the middle section 3, along with continuous movement of the push plates 6, after the driving rod 2 and the two limiting plates 602 are staggered, limiting of the driving rod 2 is cancelled, at this time, the two friction plates 604 drive the middle section 3 to rotate, at this time, the rotation direction of the middle section 3 is the direction in which the external thread 203 is screwed into the internal thread 402, and because the driving rod 2 is inserted into the flat hole 301, the rotation of the middle section 3 can drive the driving rod 2, and then based on the downward extrusion force of the elastic telescopic piece to the driving rod 2, the external thread 203 can be driven to smoothly screw into the internal thread 402, so as to realize the screwing of the driving rod 2 into the screw base 4. Therefore, in the process of returning and moving the two pushing plates 6 (namely, in the process of reversely moving the power output ends of the two pushing mechanisms), unexpected technical effects are generated on the two friction plates 604, so that the screw connection between the driving rod 2 and the screw base 4 can be realized, the bead spinning device in the prior art is omitted, and the structure of the assembly machine is further reduced. The sum of the friction force between the lipstick holder 201 and the barrel 1 and the friction force between the middle section 3 and the screw base 4 is smaller than the sum of the friction force between the two friction plates 604 and the middle section 3, so that the two friction plates 604 can drive the middle section 3 and the driving rod 2 to rotate.

In addition, when the two push plates 6 move in the direction away from each other, the driving rod 2 is prevented from rotating between the two limiting plates 602, and the stability of the driving rod 2 is improved.
