Description

Technical Field

[0001] The utility model relates to the technical field of generator production equipment, in particular to a press-fitting tool and device for a generator diode. Background Art

[0002] During the production and assembly of the generator, the negative electrode of the diode needs to be pressed into the electric cover or the rectifier board to form a rectifier bridge structure. The diode and the slot on the electric cover or the rectifier board are interference fit. The generator rectifies the AC power into DC power through the rectifier bridge. The rectifier bridge is divided into positive and negative tubes (both positive and negative diodes have leads and bases, and the internal polarities are different). The negative tube is pressed into the electric cover, which is equivalent to the negative plate of the rectifier bridge. The negative tube is welded to the positive tube through the bracket on the bridge.

[0003] The original method of pressing the diode with the electric cover and the rectifier plate is to place the electric cover (or rectifier plate) workpiece on the mold base, and then put the diode lead wire downward into the corresponding workpiece groove, and press the diode in with the pressing head downward. Although this method can also press the diode in, the problem is that the diode may not be placed correctly when pressed in, causing the pressing device to be skewed and damage the diode. Summary of the invention

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0022] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0023] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components.

[0024] like Figure 1 and Figure 2 As shown, a press-fitting tool for a generator diode is used for installing the diode of a generator cover or a rectifier plate, and comprises a floating seat 1 and a fixed seat 2. The floating seat 1 is arranged on the upper side of the fixed seat 2, and a spring 3 is connected between the floating seat 1 and the fixed seat 2. The floating seat 1 is provided with a plurality of mounting holes penetrating upward and downward, and each mounting hole is provided with a pressing column 4 which can slide upward and downward, and the lower end of the pressing column 4 extends out of the mounting hole and is connected to the fixed seat 2, and the upper end of the pressing column 4 is lower than the upper end of the mounting hole.

[0025] Insert the diode base into the mounting hole, and make the diode base and the upper end of the pressure column 4 fall flat and abut against each other, place the generator cover or rectifier plate on the floating seat 1, align the diode mounting groove of the cover or rectifier plate with the diode base, and let the diode lead pass through the diode mounting groove upward. After the preparation is completed, use the upgrade machine to press down the cover or rectifier plate, and the cover or rectifier plate drives the floating seat 1 to be pressed down. The floating seat 1 overcomes the elastic force of the spring 3 and moves downward to contact with the fixed seat 2. Since the fixed seat 2 has a lower limit on the pressure column 4, the pressure column 4 will not move down with the floating seat 1. The pressure column 4 pushes the base of the diode upward relative to the floating seat 1, so that the base of the diode is out of the mounting hole, and is inserted into the diode mounting groove of the cover or rectifier plate through interference fit, so as to realize the automatic pressing of the diode of the cover or rectifier plate.

[0026] By providing a plurality of vertically penetrating mounting holes on the floating seat 1, and setting pressure columns 4 in the mounting holes, the floating seat 1 moves downward to make the pressure columns 4 lift up the diodes, so that multiple diodes are simultaneously pressed into the diode mounting grooves of the electric cover or the rectifier board in a forward and parallel manner, without any skewness in the press-fitting and with uniform force.

[0027] By adjusting and replacing the pressing column 4 with different lengths, the pressing stroke can be changed to meet the pressing requirements of different types of electric covers or rectifier boards, ensuring that the base of the diode is recessed in the electric cover or rectifier board to meet the process requirements.

[0028] In one embodiment, a horizontal folded edge 5 is provided at the lower end of the side wall of the floating seat 1, and a plurality of guide posts 6 are fixedly connected to the folded edge 5. The fixed seat 2 is provided with a plurality of guide holes 7 corresponding to the guide posts 6, and the guide posts 6 are slidably sleeved with the guide holes 7. Through the cooperation between the guide posts 6 and the guide holes 7, the floating seat 1 is guided to rise and fall relative to the fixed seat 2, thereby avoiding rotation and tilting, and ensuring the accuracy of press-fitting.

The positioning column 8 is used to cooperate with the corresponding groove of the electric cover or the rectifier plate to limit the horizontal position of the electric cover or the rectifier plate to prevent the electric cover or the rectifier plate from being horizontally offset; the positioning pin 9 is used to cooperate with the corresponding groove of the electric cover or the rectifier plate to prevent the electric cover or the rectifier plate from rotating.

[0030] In one embodiment, the fixing seat 2 is provided with a plurality of mounting grooves, each of which is provided with a pressure sensor 10, and the pressure sensor 10 corresponds to the position of the pressure column 4 one by one, and the lower end of the pressure column 4 extends into the mounting groove and abuts against the pressure sensor 10. The pressure sensor 10 is used to detect the downward pressure of the pressure column 4, monitor the pressing force of each diode, and prevent quality problems caused by too large or too small pressing force due to poor workpiece size.

[0031] In one embodiment, the fixing seat 2 includes a bottom plate 202 and a mounting seat 201, the bottom plate 202 and the mounting seat 201 are fixed by bolts, the mounting groove vertically penetrates the mounting seat 201, the lower end of the pressure sensor 10 abuts against the bottom plate 202; a narrowing port is provided at the upper end of the mounting groove, and a baffle is provided at the lower end of the pressure column 4, and the baffle abuts against the narrowing port. The bottom plate 201 and the mounting seat 201 are arranged to be detachable, so that it is convenient to install the pressure sensor 10 into the mounting groove, and by providing a narrowing port at the upper end of the mounting groove, the pressure column 4 is limited to prevent the pressure column 4 from falling out.

[0032] A press-fitting device for a generator diode includes the above-mentioned tooling, an integral press head 11 and a lifting drive device; the lifting block of the lifting drive device is connected to the integral press head 11, and the tooling is fixedly arranged below the integral press head 11. The integral press head 11 is used to contact with the electric cover or the rectifier plate to apply force to press down the electric cover or the rectifier plate, and the lifting drive device is used to drive the integral press head 11 to move up and down.

[0033] In one embodiment, the structure of the electrical cover 14 is as follows Figure 4 As shown, the diode base 12 is placed under the electric cover 14, the diode lead 13 extends from the corresponding notch of the electric cover 14, and the integral pressing head 11 presses down the electric cover 14 to make the diode base 12 snap into the corresponding notch of the electric cover 14 from the bottom of the electric cover 14.
