Description

Technical Field

[0001] The present application relates to the technical field of rivet machines, and in particular to a rivet machine with an automatic feeding function. Background Art

[0002] A riveting machine is a mechanical device that rivets objects together. It primarily operates on the principle of cold rolling, completing assembly through rotation and pressure. It offers advantages such as high processing efficiency, precise positioning, time and labor savings, and consistent quality. A rivet consists of a rivet body and a mandrel, which is inserted into the rivet body.

[0003] Chinese patent publication number CN106391975A discloses an automatic rivet feeding mechanism for a riveting press, comprising a vibrating feeder, a push rod mechanism, a conveying hose, a grating sensor, and a riveting press. The vibrating feeder is located above the riveting press, with its feed port extending toward the feed side of the riveting press. The front end of the feed port is connected to an L-shaped slot plate, on which the grating sensor is mounted. The horizontal section of the L-shaped slot plate is provided with a rivet slot, which is located on the guide path of the push rod. The conveying hose is mounted on the riveting press and maintains the conveying hose vertically, with a funnel mounted on the top of the conveying hose. The funnel is positioned opposite the rivet slot. The present invention avoids the situation where rivets are not blown into place due to low air source pressure. It also eliminates the need for an additional rivet blowing air source and related pneumatic components for the vibrating feeder, simplifying the structure of the riveting process equipment and reducing the cost of the riveting process equipment.

[0004] With regard to the above-mentioned related technologies, the prior art uses a vibrating feeder to output rivets, and then uses a cylinder to move the rivets into a conveying hose. The rivets are guided by the conveying hose and freely fall to the riveting station of the riveting press, thereby achieving the effect of automatically conveying rivets. However, the prior art has the following problems: 1. The conveying hose is made of deformable material. Since there is no air source as auxiliary power, and the weight of the rivet is relatively light, when it falls by gravity, the conveying direction is constantly changing, and the rivet has to rub against the inner wall of the conveying hose, and there is a possibility of clogging inside the conveying hose; 2. The rivet is guided to the riveting press through the conveying hose, which means that the outlet end of the conveying hose is located at the riveting station. However, during riveting, the outlet end of the conveying hose will affect the operation of the riveting press and the product, and the position of the outlet end of the conveying hose will change at any time due to the touch of the product. It cannot be guaranteed that subsequent rivets can also be accurately conveyed to the riveting station, thereby reducing the conveying efficiency of the automatic feeding mechanism of the rivet of the riveting press.

[0007] By adopting the above technical solution, during transportation, under the pressure of an external air source, the rivet is transported individually to the positioning member through the guidance of the delivery hose and the delivery channel. At this time, the rivet body is inserted into the delivery trough, and then the rivet is transported to the limiting component by the push member. The lifting frame is lifted by the lifting member to drive the rivet up until the rivet core enters the rivet gun of the riveting machine, so that the rivet is confined to the riveting station. Then, the product can be riveted by riveting, realizing the processing of the riveting machine. Under the action of the external air source pressure, the rivet is driven to move, which reduces the possibility of the rivet stopping due to friction with the delivery hose or the inner wall of the delivery channel, ensures the smooth movement of the rivet, and then limits the rivet by the positioning member to ensure that the rivet is on the pushing path of the pushing member. Finally, the rivet is confined to the riveting station by the limiting component, realizing the precise transportation of the rivet. Compared with the existing technology, the rivet transportation efficiency of the riveting machine is improved.

[0008] Optionally, the positioning member is a limiting cylinder, the top end of the positioning member is opened, and a first inclined annular surface is provided. From bottom to top is the reference direction, the diameter of the first inclined annular surface gradually increases, and the positioning member has a conveying notch on the side facing the riveting notch.

[0009] By adopting the above technical solution, when the rivet escapes from the conveying channel, it is guided by the first inclined annular surface and enters the interior of the positioning member. Under the restriction of inertia and the positioning member, the rivet will not move or jump out, ensuring that the rivet is accurately conveyed to the conveying trough.

[0010] Optionally, a conveying rail is connected to the lifting frame, and the conveying rail includes two L-shaped plates. The two L-shaped plates are arranged opposite to each other and are parallel to the conveying trough. The L-shaped plates are located between the positioning piece and the riveting notch.

[0011] By adopting the above technical solution, when pushing the rivet, the rivet moves under the action of the pushing member and enters between the two L-shaped plates. The restriction of the L-shaped plates reduces the possibility of the rivet jumping off or the angle shifting during the pushing process.

[0013] By adopting the above technical solution, the rivet is pushed by the pushing member, and the rivet moves quickly along the conveying groove to the chuck. During this process, the rivet hits the extension block, and the extension block is subjected to force, causing the chuck to move and the return spring to be compressed until the rivet is located in the clamping groove. The rivet is clamped by the clamping force of the return spring to limit the movement of the rivet, thereby realizing the delivery of the rivet to the bottom of the rivet gun; when riveting, the rivet gun descends, driving the lifting frame and the lifting member to descend to the specified position. During this process, the lifting member drives the lifting frame to rise, and the rivet gun applies pressure on the second inclined annular surface, the chuck moves, the rivet body detaches from the chuck, and passes through between the two products. The rivet gun extracts the nail core, causing the rivet body to deform, thereby realizing the riveting of the two products. The rivet gun rises, and finally the lifting member drives the lifting frame to descend, the chuck detaches from the rivet gun, and the chuck is restored.

[0014] Optionally, a controller is installed on the machine body, and proximity sensors are installed on the lifting frame at positions corresponding to the positioning member and the chuck. The pushing member is a pushing cylinder, which is installed on the lifting frame, and the output end is located in the conveying trough. The lifting member is a lifting cylinder, which is connected to the rivet gun of the machine body, and the output end is connected to the lifting frame. The pushing member, the lifting member and the proximity sensor are all electrically connected to the controller.

[0015] By adopting the above technical solution, when the rivet is transported to the position of the positioning part, it is sensed by the proximity sensor there. The proximity sensor there sends an electrical signal to the controller, which starts the pushing part to move the rivet to the limiting component. The proximity sensor there senses the rivet and sends an electrical signal to the controller to start the lifting part, which makes the lifting frame rise, drives the rivet to rise, and makes the nail core enter the rivet gun, thereby achieving the effect of automatic rivet transportation.

[0016] Optionally, a T-rail is vertically connected to the rivet gun of the machine body, a stop block is connected to the bottom end of the T-rail, a connecting block is connected to the lifting frame, and the connecting block is slidably fitted on the T-rail. When the rivet is located on the positioning piece, the connecting block abuts against the stop block.

[0017] By adopting the above technical solution, the moving direction of the lifting frame is limited by the T-rail, making the lifting of the lifting frame more stable, and the moving stroke of the lifting frame is limited by the block, thereby improving the delivery accuracy of the rivets.

[0018] Optionally, a plurality of rollers are rotatably connected to the bottom end of the body, and a support assembly is provided at a position on the body corresponding to the rollers, and the support assembly includes a support screw, a support foot, a lock nut and a spirit level.

When working, the lowest point of the roller is higher than the lowest point of the support foot.

[0019] By adopting the above technical solution, the machine body is moved to the specified position through the rollers, and the support legs are rotated using tools to lower the support legs until the rollers at that location are off the ground. Similarly, the machine body is leveled on all sides according to the spirit level, and finally the anti-loosening nut is rotated so that the anti-loosening nut presses against the support legs to stabilize the support legs, thereby achieving the installation of the machine body at the specified position.

[0020] Optionally, an installation notch is provided on the machine body at a position corresponding to the bottom of the lifting frame, and a material receiving box is detachably connected to the installation notch. The top and one side wall of the material receiving box are both opened, and a baffle is rotatably connected to the side wall of the material receiving box. The rotation center of the baffle is located at the top, and the baffle covers the side wall of the material receiving box. A stabilizing member for reducing the shaking of the baffle is provided on the material receiving box, and a cleaning component for assisting in cleaning the nail core is provided in the material receiving box.

[0021] By adopting the above technical solution, after the product is riveted, the nail core in the rivet gun is waste and will fall from the rivet gun. A receiving box is provided to receive the fallen nail core; when cleaning, the cleaning component is used to move the waste to the baffle, and the baffle is opened, and the waste is handled uniformly, which facilitates the disposal of the waste.

The material receiving box is slidably fitted on the machine body through the mounting plates. The two opposite side walls of the mounting plates are connected with limiting flanges, and a limiting groove is provided on the machine body. When installed, the limiting flange is located in the limiting groove.

[0025] By adopting the above technical solution, the staff can remove the material receiving box for cleaning and maintenance. During installation, the material receiving box is inserted into the installation notch so that the bottom wall of the installation notch is located between the two mounting plates. During this process, the limiting flange contacts the machine body, causing the mounting plate to deform slightly until the limiting flange enters the limiting groove, thereby limiting the freedom of the material receiving box and realizing the installation of the material receiving box.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. During transportation, under the pressure of an external air source, the rivets are transported individually to the positioning parts through the guidance of the conveying hose and the conveying channel. At this time, the rivet body is inserted into the conveying trough, and then the rivet is transported to the limiting component by the pushing part. The lifting frame is lifted by the lifting part to drive the rivet up until the rivet core enters the rivet gun of the riveting machine, so that the rivet is confined to the riveting station.
