The device provided by the invention realizes automatic gluing and automatic press fitting operation of the workpiece assembly surface, improves the assembly efficiency and reduces the labor intensity.
In order to more clearly understand the technical solution of the present invention, the following describes the operation process of an embodiment of the present invention.
With the apparatus of the present invention, the gluing of the inner hole 110 of the first workpiece 11 and the press-fitting operation (i.e., the fitting operation) of the first workpiece 11 and the second workpiece 100 can be performed by the cooperation of the respective constituent mechanisms. The specific operation steps are as follows:
and step 2, placing a first workpiece 11 on a three-foot positioning seat 13 at the front end of a rotary table 14 (namely the three-foot positioning seat 13 of the feeding station), starting the device, and enabling the first workpiece 11 to be clockwise shifted to the next station under the driving of a cam divider 10 and the rotary table 14.
And step 3, the first workpiece 11 reaches a gluing position (namely, a position right to the dispensing cylinder 15), the upper feeder 82 extrudes the lower feeder 81, the upper feeder and the lower feeder are fully contacted under the action of the spring 813, a power supply circuit of the motor 23 is switched on, and the motor 23 is started to drive the three-foot positioning seat 13 and the first workpiece 11 to rotate at a constant speed.
And step 4, simultaneously, the first sensor 201 senses the first workpiece 11, the first sensor 201 sends a trigger stop control signal to the cam divider 10, the cam divider 10 is controlled to stop rotating, and a trigger start signal is sent to a controller of the gluing cylinder 22, so that the gluing mechanism is started, the gluing cylinder 22 pushes the dispensing cylinder 15 to the direction of the first workpiece 11, the glue outlet nozzle 152 is in contact with the inner hole wall of the first workpiece 11, the glue dispensing machine controls the glue dispensing amount of the dispensing cylinder 15, the glue outlet nozzle 152 and the glue dispensing head 153 start glue dispensing, glue is applied to the inner hole 110 hole wall of the first workpiece 11 under the driving rotation of the first workpiece 11 by the motor 23, and when the glue on the hole wall rotates to the position of the glue scraping plate 151, the glue scraping plate 151 can expand and uniformly apply the glue applying area.
