Description

Technical Field

[0001] This utility model relates to the field of riveting technology, specifically to a pin riveting device. Background Technology

[0002] Riveting is an important assembly process in manufacturing. Riveting refers to the connection of rivets, which uses axial force to thicken the rivet shank within the rivet hole, forming a rivet head, thus connecting multiple parts. In the production of liquid level sensors, riveting operations are required on the frame to fix and connect multiple parts; specifically, the pre-installed rocker arm needs to be riveted and fixed to the frame. The frame is a key component of the liquid level sensor, serving to support and fix other sensor components. The frame's structural design allows it to stably support key components such as the resistive element, slider, and lever support, maintaining the relative positions of these components. In liquid level sensors, the rocker arm is a key component of mechanical liquid level detection, typically used in float-type liquid level sensors or mechanically linked liquid level switches. Its core function is to transmit liquid level change signals through mechanical movement, realizing liquid level measurement and signal conversion, thereby achieving liquid level detection or control functions.

[0052] Example

[0053] Please refer to Figure 1-5 This embodiment provides a pin riveting device, including: a frame 66 and a pin feeding fixture 610; the pin feeding fixture 610 is typically fixedly mounted on the frame 66, and has a feeding channel inside for accommodating pins 612, wherein the diameter of the feeding channel matches the outer diameter of the pins 612, and the feeding channel can hold a row of pins 612; the frame 66 has two paired vertical plates, and an installation space is provided between the two vertical plates, in which the pin feeding fixture 610 is installed. A pushing mechanism 69 is provided on the first side of the pin feeding fixture 610, and the pushing mechanism 69 is used to extend into the feeding channel to push the target pin to the second side of the pin feeding fixture 610; the pushing mechanism 69 can also be installed in the installation space of the frame 66. Preferably, the first side and the second side of the pin feeding fixture 610 are opposite each other. The pressing module 63 is located on the second side of the pin feeding fixture 610 and corresponds to the pushing mechanism 69. The pressing module 63 is used to press the target pin pushed by the pushing mechanism 69. The pressing module 63 presses the target pin pushed by the pushing mechanism 69 into the workpiece to achieve riveting. In this embodiment, the workpiece is a frame 67, and parts such as rocker arms are riveted on the frame 67.

[0054] like Figure 1-3 In one embodiment shown, the pin feeding fixture 610, the pushing mechanism 69, and the pressing module 63 are vertically mounted. The feeding channel within the pin feeding fixture 610 is vertically arranged. The vibratory feeder 61 feeds the pins 612 (i.e., when supplying pins 612), and the pins 612 move vertically within the feeding channel by their own weight and arrange themselves in a row. The pushing mechanism 69 is located below the pin feeding fixture 610. The pushing mechanism 69 extends into the vicinity of the outlet of the feeding channel and pushes the target pins to the pressing module 63 opposite to the pushing mechanism 69. The pressing module 63 acts downward to rivet the target pins onto the frame 67.

[0055] like Figure 3-5In one embodiment shown, the pushing mechanism 69 includes a pusher 691 and a pushing drive 692. The pushing drive 692 is located at the first end of the pusher 691; the pushing drive 692 is used to drive the pusher 691 to push the target pin to the execution end of the pressing module 63, wherein the pusher 691 carries the target pin into the execution end of the pressing module 63.

Preferably, the outline of the pusher 691 is square, and the square shape can cooperate with the groove 6103 on the pin feeding fixture 610. The groove 6103 guides the pusher 691 so that the target pin is accurately delivered to the preset position below the pressing module 63.

[0056] like Figure 4 , 5 In one embodiment shown, the pin feeding fixture 610 includes: a fixing block 6101 and an inner core 6102; the inner core 6102 is disposed on the fixing block 6101, and a feeding channel is provided inside the inner core 6102. Preferably, two fixing blocks 6101 are provided and distributed on both sides of the inner core 6102, with each fixing block 6101 fixed to a vertical plate on one side; the inner core 6102 is composed of two core plates to achieve a detachable connection of the core plates, so as to allow for inspection and maintenance of the feeding channel formed by the combination of the two core plates. The fixing block 6101 has a groove 6103 formed on it for guiding the movement of the transfer module 693, and the shape of the groove 6103 is square, matching the contour of the pusher 691.

[0057] like Figure 3-5 In one embodiment shown, the pin riveting device further includes a stop mechanism 611 disposed on the side of the pin feeding fixture 610; the stop mechanism 611 is used to extend into the feeding channel to stop the pin 612 adjacent to the target pin. Preferably, the stop mechanism 611 stops the pin 612 adjacent to the target pin so that the pushing mechanism 69 pushes one target pin at a time or the transfer module 693 carries one target pin at a time, such as... Figure 4In one embodiment, a stop mechanism 611 is disposed on the first side of the pin feeding fixture 610, on the same side as the pushing mechanism 69, and located above the pushing mechanism 69. Specifically, the stop mechanism 611 includes a push rod 6111 and a push drive member 6112; the push drive member 6112 is disposed at the first end of the push rod 6111, and the push drive member 6112 is used to drive the second end of the push rod 6111 to extend into the feeding channel of the pin feeding fixture 610 to stop the pin 612 adjacent to the target pin.

[0058] like Figure 1-3 In one embodiment shown, the top pressing module 63 includes a top pressing rod 632 and a top pressing drive member 631. The top pressing rod 632 is arranged vertically, and the top pressing drive member 631 is located at the first end of the top pressing rod 632 and fixed to the top of the frame 66. The top pressing drive member 631 drives the second end of the top pressing rod 632 to push the target pin into the pin hole of the workpiece.

[0059] like Figure 1-3 In one embodiment shown, the top-pressing module 63 further includes a guide block 633. The guide block 633 is fixedly disposed within the mounting space of the frame 66 and has a guide hole that mates with the top-pressing rod 632. The guide hole guides the movement of the top-pressing rod 632 so that the top-pressing rod 632 can move vertically downward to press the target pin for riveting, avoiding misalignment with the target pin. The top-pressing rod 632 may extend into or even pass through the receiving channel of the transfer module 693 to rivet the target pin within it.

[0060] like Figure 1-3In one embodiment shown in Figure 5, the pressing module 63 further includes a pin receiving mechanism 68; wherein the pin receiving mechanism 68 is disposed on the guide block 633; ​​the pin receiving mechanism 68 is used to receive the target pin pushed by the pushing mechanism 69, and then the pressing module 63 can press down to receive the target pin on the pushing mechanism 69 and rivet it onto the frame 67 below the pin receiving mechanism 68; specifically, the pin receiving mechanism 68 includes a push rod 682 and a carrier plate 681; the carrier plate 681 is disposed at the second end of the push rod 682; the push rod driving member 684 is disposed at the first end of the push rod 682 and connected to the guide block 633, the push rod driving member 684 is used to drive the carrier plate 681 to dock with the pushing mechanism 69 to receive the target pin pushed by the pushing mechanism 69, for example, the push rod driving member 684 drives the carrier plate 681 to move up and down to align with the groove 6103 to receive the transfer module 693. The push rod 682 passes through the guide block 633 and slides in engagement with it, allowing the guide block 633 to guide the movement of the push rod 682. The guide block 633 is preferably I-shaped, with a guide hole located on its central axis. The push rod 682 has two mating parts, positioned symmetrically on either side of the central axis, and passes through the two support arms of the guide block 633. To achieve the effect of simultaneously driving the push rod 682 with the push rod drive 684, a transition plate 683 is provided between the push rod drive 684 and the push rod 682. The transition plate 683 has a notch in the middle to avoid the vertical beam in the middle of the guide block 633. The lugs on both sides of the notch are connected to the first end of the push rod 682 respectively. The two ends of the carrier plate 681 are connected to the second end of the push rod 682 respectively. The actuator end of the push rod drive 684 is connected to the transition plate 683 so that it can drive the two push rods 682 to move synchronously, thereby driving the carrier plate 681 to move up and down and dock with the pusher mechanism 69.

[0061] like Figure 1-3 In one embodiment shown, the pin riveting device further includes a clamp 64 for clamping the workpiece; the clamp 64 is positioned opposite the top pressing module 63 and may be located below the pin receiving mechanism 68.

[0062] like Figure 1-3In one embodiment shown, the pin riveting device further includes a workpiece positioning mechanism 65. The workpiece positioning mechanism 65 positions the workpiece so that the pin hole of the workpiece aligns with the second end of the top pressure rod 632. Specifically, the workpiece positioning mechanism 65 includes an X-axis module 652 and a Z-axis module 651. The X-axis module 652 drives the workpiece positioning mechanism 65 to move along the X-axis. The Z-axis module 651 is located on top of the X-axis module 652 and drives the workpiece positioning mechanism 65 to move along the Z-axis. A positioning pin 653 is located at the actuating end of the Z-axis module 651. The positioning pin 653 moves along the X-axis and Z-axis to insert into the pin hole of the workpiece and position it. The connection between the X-axis module 652 and the Z-axis module 651 can be a sliding fit. When the X-axis module 652 moves to a predetermined position and stops, the Z-axis module 651 can slide up and down at the connection to achieve lifting and lowering.

[0063] like Figure 1-3 In one embodiment shown in Figure 5, the pin riveting device further includes: a vibratory feeder 61 for vibratory feeding; the outlet of the vibratory feeder 61 is connected to the first end of a guide tube 62, and the second end of the guide tube 62 is connected to a pin feeding fixture 610. The vibratory feeder 61 vibrates to feed the pins 612 into the feeding channel through the guide tube 62; the pins 612 slide along the guide tube 62 into the feeding channel of the pin feeding fixture 610 and are arranged in a row.

[0064] In the above, the pusher drive 692, the pusher drive 6112, the press drive 631, and the push rod drive 684 are pneumatic cylinders or hydraulic cylinders; among them, pneumatic cylinders are preferred.

[0065] This utility model discloses a pin riveting device. A vibratory feeder 61 feeds pins 612 vertically to a predetermined position on a pin feeding fixture 610. A stop mechanism 611 abuts against the second pin 612 at the outlet of the feeding channel to prevent movement. A pushing mechanism 69 pushes the first pin 612 (the target pin) onto the coaxiality of the frame 67 and the rocker arm shaft hole. A pressing module 63 presses the pin 612 down and rivets it into the frame 67 for fixation. The pin hole is a flared hole for easy riveting. A sensor can be installed below the clamp 64 in the pin riveting device to detect whether the pin 612 is installed correctly. After installation, a guide mechanism pushes the rocker arm to 45 degrees.

[0066] The above describes the technical solution of the pin riveting device from the perspective that the pin feeding fixture 610, the pushing mechanism 69, and the pressing module 63 are generally arranged vertically, achieving the effect of pressing the pressing module 63 downward to rivet the pin 612. It can be understood that the above mechanism can be arranged horizontally, so that the pressing module 63 can rivet the pin 612 in the horizontal direction.

[0067] This utility model's pin riveting device, through the cooperation of the pushing mechanism 69 and the pressing module 63, avoids the instability and inefficiency of manual feeding and riveting, making the entire riveting process smoother and more efficient. It achieves automatic feeding and riveting of the pin 612, greatly improving production efficiency. The diameter of the feeding channel matches the outer diameter of the pin 612, and the cooperation between the feeding channel and the transfer module 693 ensures the stability and accuracy of the pin 612 during feeding. The pushing mechanism 69 can accurately push the target pin to the designated position, while the pressing module 63 can accurately press the pin 612, achieving precise riveting. The above-mentioned automated riveting process reduces interference from human factors, improves the accuracy and consistency of riveting, ensures the connection strength and stability between workpieces, and thus improves the overall quality of the product.

[0068] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model.
