Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
Fig. 1 is the structure diagram of the present invention, fig. 2 is the cross-sectional view of the present invention, and fig. 3 is the structure diagram of the connecting block of the present invention.
An adjustable glue applying mechanism comprises a linear driving mechanism 1, a rotary motor 2, a driving gear 3, a driven gear 4, a limiting block 5, a machine shell 6, a machine frame 7, a glue spraying head 8, a shaft cylinder 9, a connecting block 10 and a mandril 11, linear drive mechanism 1's cylinder body and stopper 5 are fixed respectively at frame 7 both ends, 6 sliding connection of casing are in frame 7, rotary motor 2's organism is fixed on casing 6, rotary motor 2's output shaft end is fixed with driving gear 3, driving gear 3 meshes with driven gear 4 mutually, driven gear cover establishes and fixes on beam barrel 9, ejector pin 11 is arranged in the vertical passageway of beam barrel 9, connecting block 10 sliding fit connects in the horizontal passageway of beam barrel 9, set up the bell groove 12 that is used for inserting ejector pin 11 on the connecting block 10, connecting block 10 rotates with glue-spraying head 8 and is connected, linear drive mechanism 1's piston rod and 6 swing joint of casing. The end of the piston rod of the linear driving mechanism 1 is fixed with a connecting sleeve 13, the bottom end of the connecting sleeve is fixedly connected with the ejector rod 11 through a ball bearing 14, the connecting sleeve 13 penetrates through a concave plate 15, the concave plate 15 cannot penetrate through a boss of the connecting sleeve 13 and the end face of the ball bearing 14, and a side plate of the concave plate 15 is fixed on the machine shell 6. A sliding block 16 is fixed at the side end of the machine shell 6, and the sliding block 16 is connected to a sliding rail of the machine frame 7 in a sliding fit mode. The linear driving mechanism 1 is a cylinder or an oil cylinder. And a return spring is arranged between the connecting block 10 and the horizontal channel of the shaft barrel 9.
Referring to fig. 1 and 2, first, the rotation motor 2 is started, the output shaft of the rotation motor drives the driving gear 3 to rotate, and the driving gear 3 drives the driven gear 4 engaged with the driving gear to rotate synchronously. The driven gear 4 and the shaft cylinder 9 fixed thereto rotate in synchronism. At this time, the push rod 11 is not pressed to the connecting block 10, and the glue spraying head 8 connected with the bottom of the connecting block 10 is positioned on the axis in the shaft cylinder 9. The connecting block 10 rotates synchronously with the shaft barrel 9.
Then the piston rod of the linear driving mechanism 1 extends out to drive the casing 6, the shaft cylinder 9 and the glue spraying head 8 to move linearly along the slide rail at the side end of the frame 7. After the sliding block 16 at the side end of the casing 6 moves downwards and abuts against the limiting block 5, the piston rod of the linear driving mechanism 1 continues to extend downwards, and at the same time, the connecting sleeve 13 at the end of the piston rod extends downwards along the through hole of the concave plate 15, so that the ejector rod 11 is pressed downwards. The ball bearing 14 fixed on the mandril 11 can greatly reduce the friction with the shaft barrel 9, and the mandril 11 does not rotate along with the shaft barrel 9.
At this time, the push rod 11 moves downwards, and the tapered end of the push rod 11 is inserted into the tapered groove 12 of the connecting block 10. The conical surface of the conical end of the mandril 11 extrudes the conical surface of the conical groove 12, so that the connecting block 10 can be extruded to move horizontally along with the gradual penetration of the mandril 11. The deeper the push rod 11 goes into the tapered groove 12, the further the connecting block 10 moves. When the connecting block 10 is pushed by the push rod 11, the glue-spraying head 8 at the bottom of the connecting block 10 deviates from the axis of the shaft cylinder 9, and the glue-spraying head 8 starts to eccentrically rotate. The glue-jet head 8 at this time starts to rotate in a circular orbit.
The glue spraying head 8 running according to the circular track can be attached to the inner wall of the cylindrical workpiece to perform gluing operation. When the radius of the circular track of the glue spraying head 8 is matched with the radius of the cylindrical workpiece, the moving distance of the connecting block 10 can be adjusted by only adjusting the depth of the ejector rod 11 inserted into the conical groove 12, and then the distance of the glue spraying head 8 deviating from the axis is adjusted, so that the radius adjustment of the circular track is realized.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
