Technical Field

[0001] The invention belongs to the technical field of textile machinery, and in particular relates to a pre-pressing device and method for a spindle bladder combination piece and a spindle seat. Background Art

[0002] In the assembly of the JWD6811ES series spindle base assembly, the press-fitting of the spindle bladder assembly and the spindle foot is a key process, involving the qualified flow of the bonding force and the rejection of the unqualified. This process can be guaranteed by the program setting of the modern servo electric cylinder and the judgment of the pressure displacement curve. However, before the press-fitting process, the spindle bladder assembly equipped with the vibration absorbing coil spring and the positioning sleeve must be pressed into the spindle foot. The size of the inner hole of the spindle foot is φ , the outer diameter of the vibration absorbing coil spring (elastic) is φ , the outer diameter of the positioning sleeve is φ , the outer diameter of the bearing seat cone is φ Since the inner hole of the spindle foot is very different from the outer diameter of the vibration-absorbing coil spring, the positioning sleeve and the outer diameter of the bearing seat cone, it is difficult to assemble the spindle bladder combination and the spindle foot manually. When the automatic assembly line uses a robot for pre-assembly, it is even more difficult before press-fitting. Summary of the invention

[0003] In order to solve the problem of enabling the ingot bladder assembly equipped with a vibration-absorbing coil spring and a positioning sleeve to be smoothly pre-pressed into the ingot foot before the ingot bladder assembly and the ingot foot are press-fitted on an automatic assembly line, the present invention provides a pre-pressing device and method for an ingot bladder assembly and an ingot seat.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a pre-pressing device for an ingot bladder combination and an ingot seat, comprising: a straight robot, an ingot foot, a first cylinder, a first clamp, a second cylinder, a second clamp, a third cylinder, a turntable, an ingot bladder combination, a vibration-absorbing coil spring, a positioning sleeve, a spring, a turntable positioning tooling, and a photoelectric sensor. The straight robot is connected to the ingot foot through a claw hand, wherein the straight robot grabs the ingot foot and moves it to just above the ingot bladder combination, the straight robot is electrically connected to the PLC, the first clamp is connected to the first cylinder, the first cylinder is connected to the third cylinder, the second clamp is connected to the second cylinder, the second cylinder is connected to the third cylinder, the photoelectric sensor is connected to the third cylinder, the spring is arranged between the second cylinder and the third cylinder, and the two ends of the spring are respectively connected to the second cylinder and the third cylinder, the vibration-absorbing coil spring and the positioning sleeve are arranged on the ingot bladder combination, the ingot bladder combination is connected to the turntable positioning tooling, and the turntable positioning tooling is connected to the turntable.

[0005] A method for pre-pressing an ingot bladder assembly and an ingot seat, comprising the following steps:

[0006] Step S1, after the ingot bladder combination is equipped with the positioning sleeve and the vibration absorbing coil spring, the turntable is turned to the ingot foot pre-pressing station;

[0007] Step S2, the robot grabs the ingot foot and moves to above the ingot bladder combination;

[0008] Step S3, the third cylinder at the bottom drives the first cylinder and the second cylinder to move forward as a whole and align with the turntable positioning tooling;

[0009] Step S4, the first cylinder below controls the first clamping jaw to clamp the vibration absorbing coil spring part, and the second cylinder controls the second clamping jaw to clamp the positioning sleeve and the outer cone part of the bearing seat;

[0010] Step S5, the straight robot grabs the spindle foot and presses it downward at a uniform speed to align the center. After the vibration-absorbing coil spring is partially pressed into the spindle foot, the first cylinder controls the first clamp to release;

[0011] Step S6, the ingot foot continues to be pressed downward at a uniform speed until the second cylinder controls the second clamp to not release the positioning sleeve part, and the spring is compressed to continue to press the conical outer circle section of the bearing seat into the ingot foot. The second cylinder controls the second clamp to release, ensuring that the ingot bladder combination is pre-pressed into the ingot foot.

[0012] The beneficial effects of the present invention are as follows: the spindle foot continues to be pressed downward at a uniform speed until the two jaws of the cylinder on the positioning sleeve part are not released, and the cone outer circle section of the bearing seat is continuously pressed downward into the spindle foot with the compression of the spring, and the two jaws of the cylinder are released, ensuring that the spindle bladder combination is pre-pressed into the spindle foot, ensuring that the subsequent servo electric cylinder is pressed smoothly. It has high assembly accuracy, replaces traditional manual press fitting, and improves overall production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
