[0039] like Figures 1-3 As shown, this utility model provides a riveting machine with a high-precision counting function, including a riveting machine main unit 3. The riveting machine main unit 3 is powered by one of the following: pneumatic lever type, pneumatic, hydraulic type, or pneumatic-hydraulic type, which drives the riveting shaft to rise and fall to realize the riveting operation. A counting mechanism 1 is installed on the riveting machine main unit 3, and the counting mechanism 1 rises and falls with the riveting shaft of the riveting machine main unit 3. When the riveting shaft of the riveting machine main unit 3 descends to rivet, the counting mechanism 1 is triggered to generate a counting signal, which is transmitted to the riveting machine main unit 3 for display.

[0040] Specifically, the counting mechanism 1 includes a fixing part 101, a counting signal generating part 102, and a triggering device 103. The fixing part 101 is fixed to the lower part of the outer surface of the riveting shaft of the riveting machine host 3. The counting signal generating part 102 is installed on the side of the fixing part 101 and rises and falls with the fixing part 101. The triggering device 103 is located at the bottom of the counting signal generating part 102. During the riveting process of the riveting machine host 3, the triggering device 103 is forced to move upward, thereby triggering the counting signal generating part 102, causing the counting signal generating part 102 to transmit a counting signal to the riveting machine host 3. This physical data triggering method can effectively avoid invalid counting due to operator error. An information transmission cable 104 is provided on the side of the counting signal generating part 102. The information transmission cable 104 is connected to the host signal of the riveting machine host 3 to achieve the purpose of power supply and signal transmission. When the counting signal generator 102 is triggered to issue a counting signal, the signal is transmitted to the interface board of the riveting machine host 3 through the information transmission cable 104, and the count is displayed on the display screen on the riveting machine host 3.

[0041] like Figure 2 As shown, in some embodiments, the fixing part 101 of this utility model is generally a clamp or other detachable fixing structure, which is fixed to the riveting shaft of the riveting machine host 3 by bolts, thereby facilitating the modification of the existing riveting machine host 3. Furthermore, it can be easily disassembled for replacement or repair after the counting mechanism 1 malfunctions. The installation position of the triggering device 103 can be adjusted vertically, thereby adapting to rivets of different lengths and workpieces of different thicknesses, and improving the triggering sensitivity of the triggering device 103.

[0042] like Figure 4 As shown, in some embodiments, the counting signal generator 102 of this utility model includes a protective shell 1021, and the interior of the protective shell 1021 is provided with a cavity. A touch switch 1022 and a terminal block 1023 are respectively disposed in the cavity inside the protective shell 1021. The touch switch 1022 is energized each time it is triggered, and after being energized, the touch switch 1022 transmits a predetermined signal outward. The touch switch 1022 and the terminal block 1023 are electrically connected, and the touch switch 1022 is plugged into an information transmission cable 104. The signal generated by the touch switch 1022 is transmitted to the riveting machine host 3 through the information transmission cable 104 connected to the terminal block 1023. The main board of the riveting machine host 3 receives the signal through the interface board, converts the signal into a digital signal, and displays it on the display screen of the riveting machine host 3.

[0043] A support cylinder 1024 is provided at the bottom of the protective shell 1021, and the support cylinder 1024 communicates with the cavity inside the protective shell 1021. A trigger device 103 is disposed in the support cylinder 1024, which supports and limits the trigger device 103. When driven, the trigger device 103 moves along the support cylinder 1024 into the interior of the protective shell 1021, causing its end to contact the switch of the trigger switch 1022, energizing the trigger switch 1022 to send a counting signal.

[0044] like Figure 4 As shown, in some embodiments, the triggering device 103 of this utility model includes a traction slider 1031, the diameter of which is the same as the inner diameter of the support cylinder 1024 to ensure stable movement of the traction slider 1031 inside the support cylinder 1024. An actuating rod 1032 is provided at the axial center of the upper end of the traction slider 1031, extending into the cavity of the protective shell 1021. When the traction slider 1031 is driven, the actuating rod 1032 moves accordingly, thereby applying pressure to the switch 1022, energizing the switch 1022 to generate a signal. A driving head 1034 is provided at the bottom of the traction slider 1031, extending from the bottom of the support cylinder 1024 to the outside of the support cylinder 1024. Normally, the lower end of the drive head 1034 is flush with the lower end of the riveting shaft of the main body 3 of the riveting machine. During riveting, the drive head 1034 will be compressed by pressure to drive the trigger rod 1032 to trigger the trigger switch 1022.

[0045] like Figure 4 As shown, in some embodiments, a limiting support plate 1025 is provided at the connection between the support cylinder 1024 and the protective shell 1021 to limit the maximum travel of the traction slider 1031. The limiting support plate 1025 is penetrated by the trigger switch 1022, thereby supporting the trigger rod 1032 and enabling the trigger rod 1032 to move up and down. A return spring 1033 is provided between the top of the traction slider 1031 and the limiting support plate 1025. After the counting drive head 1034 loses pressure, in addition to moving under the action of gravity, the return spring 1033 will also apply additional force to the traction slider 1031, so that the traction slider 1031 returns to the initial position as soon as possible, releasing the contact between the trigger rod 1032 and the trigger switch 1022.

[0046] like Figure 1As shown, in some embodiments, the riveting machine host 3 of this utility model is further provided with a rivet support mechanism 2, which is detachably mounted on the operating table of the riveting machine host 3. The rivet support mechanism 2 is used to support the rivet and the workpiece. Because the rivet support mechanism 2 is frequently subjected to pressure and is a vulnerable part, its detachable mounting on the operating table of the riveting machine host 3 allows for easy replacement, improving ease of use and reducing maintenance costs.

[0047] like Figure 1 and Figure 5 In some embodiments, the rivet support mechanism 2 of this utility model includes a support base 201, which is used to connect to the operating table of the riveting machine host 3. A rivet support platform 202 is provided on the top of the support base 201. A rivet fixing hole is provided at the center of the top axis of the rivet support platform 202 for placing rivets, and the workpiece is supported by the rivet support platform 202. The axis of the rivet support platform 202 is perpendicular and collinear with the axis of the riveting shaft of the riveting machine host 3. When the riveting shaft of the riveting machine host 3 descends, it can apply vertical pressure to the rivet to achieve the riveting operation.

[0048] like Figure 6 As shown, in some embodiments, the top of the support base 201 of this utility model is provided with a stepped groove 2021, and the bottom of the stepped groove 2021 is provided with a racetrack hole 2022. The support base 201 is connected to the riveting machine host 3 through the racetrack hole 2022 and bolts, and the fixed position and angle of the support base 201 can be changed by changing the racetrack hole 2022 to adapt to different models of riveting machine host 3.

[0049] like Figure 5 and Figure 6 As shown, in some embodiments, a driving magnetic platform 203 is provided inside the stepped groove 2021 of this invention. The projected area of ​​the driving magnetic platform 203 is the same as the projected area of ​​the stepped groove 2021. The driving magnetic platform 203 is provided to seal the stepped groove 2021, protect the bolts fixing the support base 201, and reduce the oxidation rate of the bolts. At the same time, it prevents debris from filling the stepped groove 2021 during the processing.

[0050] like Figure 6 As shown, in some embodiments, the drive magnetic platform 203 of this utility model includes a sealing cover 2031, which covers the stepped groove 2021 to protect the bolts used for fixing and to prevent debris from entering the stepped groove 2021.

[0051] A magnetic strip 2032 is provided on the top of the sealing cover 2031. A magnet is provided on the shaft at the bottom of the drive head 1034, and the magnetic poles of the magnetic strip 2032 and the magnet repel each other. When the workpiece is riveted by the main body 3 of the riveting machine, the drive head 1034 can be driven by the magnetic force of the magnetic strip 2032, so that the drive head 1034 can be displaced without hard contact. This achieves protection for the drive head 1034 and the support base 201. When the riveted workpiece is an ferrous product and is magnetized, the drive head 1034 can also trigger the touch switch 1022 through hard contact, and the counting function will not fail to be triggered due to the disappearance of the magnetic force.

[0052] The specific usage process of this utility model is as follows:

[0053] The counting signal generator 102 is mounted on the riveting shaft of the riveting machine host 3 via the fixing part 101, and the bottom of the trigger device 103 is made as flush as possible with the bottom of the riveting shaft of the riveting machine host 3. The rivet is placed in the rivet support table 202, and then the workpiece is supported on the rivet support table 202. The riveting machine host 3 is started to rivet. During the riveting process, the trigger device 103 will rise and fall with the riveting shaft of the riveting machine host 3. When the trigger device 103 descends and is resisted by the workpiece or the support base 201, the trigger device 103 will retract to trigger the counting signal generator 102 to emit a counting signal. The counting signal is transmitted to the interface board of the riveting machine host 3 through the information transmission cable 104, and the signal is converted into a digital signal by the motherboard and displayed on the display screen of the riveting machine host 3.

[0054] In summary, the riveting machine with high-precision counting function of this utility model is fixed to the riveting shaft of the riveting machine host 3 by setting a fixing part 101. At the same time, a counting signal generator 102 is set on the side of the fixing part 101, and a trigger device 103 is set at the bottom of the counting signal generator 102. When the riveting machine host 3 performs riveting, the trigger device 103 will descend with the riveting shaft and eventually be compressed into the counting signal generator 102 by pressure, triggering the counting signal generator 102. The counting signal generator 102 transmits the signal to the main board of the riveting machine host 3 for counting through the information transmission cable 104, thereby avoiding the problem of inaccurate counting caused by accidental touch or obstruction.

[0055] This utility model provides a support base 201 and detachably connects the support base 201 to the main body 3 of the riveting machine. By setting a rivet support table 202 on the support base 201 to support and limit the rivets, the vulnerable parts support base 201 and rivet support table 202 can be replaced according to usage requirements.

[0056] This invention provides a driving magnetic platform 203 on the support base 201, and a magnet block is placed at the center of the shaft at the bottom of the driving head 1034. The magnetic poles of the driving magnetic platform 203 and the magnet block repel each other. When the riveting shaft of the main body 3 of the riveting machine descends, the driving magnetic platform 203 will drive the driving head 1034 to rise through magnetic force, avoiding hard contact of the driving head 1034 and effectively improving the service life of the driving head 1034.

[0057] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0058] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
