The following details the operation of the hinge assembly machine according to the present invention in connection with a preferred embodiment of the present invention:
(1) The placement of hinge parts: placing the torsion spring in the spring slot 202 with the two spring arms of the torsion spring in the spring arm slots 203; placing the second hinge piece in hinge piece slot 201 and pressing one of the spring arms down while the second bushing is in bushing slot 204; then the first shaft sleeve of the first hinge plate is placed in the shaft sleeve groove 204, the shaft sleeve of the first hinge plate is limited by the shaft sleeve groove 204, and the inner edge of the first hinge plate is blocked by the inner edge of the second hinge plate and the edge of the shaft sleeve groove 204 to be in an inclined stable state; then the connecting shaft is placed in the connecting shaft groove 4021, and at the moment, the through hole of the torsion spring, the shaft holes of the first shaft sleeves, the shaft holes of the second shaft sleeves and the connecting shaft form a concentric and coaxial position relation; then, the clamping slide piece 2052 is moved, so that one end of the clamping slide piece 2052 is positioned above the joint of the hinge piece groove 201 and the shaft sleeve groove 204, and the first hinge piece is blocked to be in a vertical state, so that the placing work of hinge parts is completed;
(2) And (3) compressing the hinge: after the placement of the hinge parts is completed, starting a pressing cylinder 301, wherein the pressing cylinder 301 drives a pressing seat 303 to vertically press under the guiding action of a pressing guide rod 302, a U-shaped clamping groove 30311 is sleeved on a first hinge piece when a hinge pressing block 3031 is pressed down, two sides of the U-shaped clamping groove 30311 are positioned on two sides of the first hinge piece, and two pressing pieces 30312 are pressed on two sides of the first hinge piece, so that the whole hinge is pressed and fixed, and the phenomenon that the assembly pressing quality of the hinge is influenced due to the displacement of the hinge in the subsequent shaft advance and pressing process is prevented;
at this time, the coupling transition block 3033 is located between the spring groove 202 and the shaft sleeve groove 204 and is used for filling the gap between the shaft sleeve groove 204 and the spring groove 202, and the transition hole 30331 is concentric and coaxial with the through hole and the shaft sleeve hole of the torsion spring, so that the subsequent coupling can smoothly pass through the gap between the shaft sleeve groove 204 and the spring groove 202 when the coupling works;
in addition, to prevent the depressing displacement of the depressing seat 303 from being too large, a plurality of elongated depressing stoppers 3032 may be provided on the depressing seat 303, and the depressing stoppers 3032 contact with the placing seat 2 to prevent the depressing seat 303 from continuing to move downward.
(3) And (3) assembling a feed shaft of the hinge: the lower pressing seat 303 descends to compress the pages, the first trigger block on the lower pressing seat 303 descends along with the lower pressing seat 303 and finally contacts and cooperates with the first trigger switch on the base 1, and the first trigger switch sends a signal to the control end of the shaft feeding cylinder 4012 to start the shaft feeding cylinder 4012; under the guiding action of the shaft-feeding guide rod 4013, the shaft-feeding cylinder 4012 drives the shaft-feeding translation seat 4014 to move towards the placement seat 2, so that the connecting shaft in the connecting shaft groove 4021 passes through the shaft holes of the first shaft sleeves, the shaft holes of the second shaft sleeves, the through holes of the torsion springs and the transition holes 30331; simultaneously, the pressing block moves towards the pressing wheel 4041 along with the movement of the shaft feeding translation seat 4014, the pressing wheel 4041 is firstly contacted with the inclined surface 4051 of the pressing block, and the connecting rod 4042 is driven to be pressed down under the guiding action of the inclined surface 4051; when the shaft inlet seat 402 reaches the end position (i.e. the position closest to the placement seat 2, the shaft inlet seat 2 can be completely touched, so that the shaft connecting groove 4021 is connected with the shaft sleeve groove 204), the pressing wheel 4041 is positioned in the arc-shaped surface 4052 at the tail end of the inclined surface 4051, the connecting rod 4042 is pressed to the lowest position to start the shaft inlet cylinder 4031, the first piston rod 40311 of the shaft inlet cylinder 4031 pushes the shaft connecting, and the shaft connecting is completely sent into the placement seat 2 from the shaft connecting groove 4021, so that the shaft inlet assembly of the hinge is completed, the whole assembly process is quite simple in operation, and the assembly efficiency of the hinge is greatly improved;
(4) Profiling of the hinge: after the advance cylinder 4031 is started, the first piston rod 40311 of the advance cylinder 4031 pushes the connecting shaft, so that the connecting shaft is completely fed into the placement seat 2 from the connecting shaft groove 4021, and meanwhile, the second piston rod 40312 of the advance cylinder 4031 drives the advance translation seat 4032, so that the third trigger block 407 on the advance translation seat 4032 moves and finally contacts and cooperates with the third trigger switch 406, and the two profiling cylinders 5011 of the profiling mechanism 5 are started; the piston rod of the profiling cylinder 5011 vertically jacks up one end of the swinging rod 5013, and the other end of the swinging rod 5013 provided with the profiling head 5014 is profiling the assembled hinge downwards by utilizing the lever principle;
because the distance between the profiling head 5014 and the placing seat 2 is limited by the length of the piston rod of the profiling cylinder 5011, the distance between the profiling head 5014 and the placing seat 2 is usually short, the profiling cylinder 5011 enables the profiling head 5014 to be profiled downwards rapidly in a short time, the structure is simpler than the structure of the existing stamping mode, and the production personnel is prevented from being injured by the punch during the operation;
in addition, the guide holes are used for ensuring that the profiling head 5014 performs accurate vertical profiling on the sleeve; a buffer spring 50145 is arranged between the annular connecting block 50144 and the guide block 101, so that damage to a hinge sheet caused by too high instantaneous speed when the profiling cone 50143 touches the hinge is prevented; a return spring 50146 is provided between the annular connection block 50144 and the guide block 101, and can assist in returning the profiling head 5014 when profiling work is completed.
In addition, it should be noted that, in the specific embodiments described in the present specification, names of various parts and the like may be different, and all equivalent or simple changes of the structures, features and principles described in the conception of the present invention are included in the protection scope of the present invention.
