Description

Technical Field

[0001] This utility model relates to the field of riveting machine technology, and in particular to an automatic feeding riveting machine. Background Technology

[0002] A riveting machine, also known as a riveting press or riveting machine, is a mechanical device used to join metals or other materials. The riveting machine transmits power to the rivet head through mechanical or hydraulic transmission, causing the rivet head to generate pressure and movement, thereby inserting the rivet into the materials to be joined and deforming the rivet to achieve the connection of the materials.

[0003] However, existing workpieces do not have a clamping device during the rivet pressing process. The workpiece is prone to displacement under the action of the rivet head, which affects the rivet pressing effect. In addition, after the existing workpiece is riveted, it usually requires manual pulling of the sliding base to pull the base out from under the rivet head in order to remove the riveted workpiece, which is quite troublesome. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic push-material riveting machine, which solves the problems that existing workpieces do not have a clamping device during the rivet pressing process, making the workpieces easily shift under the action of the rivet head, and that existing workpieces usually need to be manually pulled by a sliding base to be removed after the rivet is pressed in.

[0005] To achieve the above objectives, an automatic feeding riveting machine is provided, comprising: a riveting machine body, a hydraulic rod fixedly connected to the top wall of the riveting machine body, a rivet head fixedly connected to the output end of the hydraulic rod, a worktable fixedly connected inside the riveting machine body, a slide groove first opened on the top of the worktable, a servo motor fixedly connected to the outer wall of the slide groove first, a lead screw fixedly connected to the output end of the servo motor through a coupling, a moving block movably connected to the outer wall of the lead screw, and a moving slide fixedly connected to the top of the moving block, facilitating the movement of the moving slide without manual pulling, and facilitating the removal of the workpiece;

[0006] The top of the movable slide table is provided with a second slide groove. A sleeve is fixedly connected to the inner wall of the second slide groove. A clamping spring is fixedly connected inside the sleeve. A clamping rod is fixedly connected to the other end of the clamping spring. A slider is fixedly connected to the other end of the clamping rod. A clamping plate is fixedly connected to the top of the slider. The top of the movable slide table is provided with a second screw hole. A screw is provided inside the second screw hole. A knob is fixedly connected to the other end of the screw to facilitate the clamping of the workpiece.

[0007] According to the automatic push-material riveting machine, a guide rod is fixedly connected to the inner wall of the slide groove, and a guide hole is opened on the side of the moving block. The moving block is slidably connected to the outer wall of the guide rod through the guide hole, which facilitates the guidance and limiting of the moving block.

[0008] According to the automatic push-material riveting machine, a screw hole is provided at the center of the side of the moving block, and the inner wall of the screw hole is provided with threads. The screw hole engages with the lead screw through the threads, which facilitates the movement of the moving block and the moving slide.

[0009] According to the automatic push-material riveting machine, the shape and size of the clamping rod are matched with the shape and size of the sleeve, and the clamping rod is slidably connected to the inner wall of the sleeve to facilitate the movement of the slider.

[0010] According to the automatic push-and-rivet machine, the inner wall of the screw hole and the outer wall of the screw are both provided with threads. The screw hole and the screw are engaged by the threads, which facilitates the movement and positioning of the clamping plate.

[0011] According to the automatic push-material riveting machine, the shape and size of the slider are matched with the shape and size of the second groove. The slider is slidably connected to the inner wall of the second groove under the action of the screw, which facilitates the movement of the slider.

[0012] According to the automatic feeding riveting machine, the outer wall of the clamping plate and the inner wall of the slide groove are both provided with rotating shaft seats, and one end of the lead screw and one end of the screw rod are respectively rotatably connected to the rotating shaft seats to facilitate the rotation of the lead screw and the screw rod.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] 1. This automatic push-type riveting machine has four sliding grooves on the top of the moving slide table, and a slider is set inside the four sliding grooves. At the same time, a screw hole and a screw are set on the top of the moving slide table. Through the cooperation of the screw hole and the screw, when the screw rotates, one end of the screw pushes the slider to move and drives the clamping plate to clamp the workpiece. By clamping the workpiece in sequence by the four clamping plates, the stability of the workpiece pressing into the rivet process is improved.

[0015] 2. This automatic push-material riveting machine uses a servo motor to drive the lead screw to rotate, which in turn drives the moving slide to move within the slide groove. After the workpiece is riveted, the moving slide can be moved out from under the rivet head without manual pulling, thus improving the practicality of the automatic push-material riveting machine.

[0030] Working principle: The workpiece is placed on the movable slide 13, and four screws 21 are rotated in sequence. One end of the screw 21 pushes the slider 18 to move, which in turn drives the clamping plate 19 to clamp the workpiece. After the four clamping plates 19 clamp the workpiece in sequence, the position of the workpiece is fixed, which improves the stability of the workpiece pressing into the rivet process. After the workpiece is clamped, the servo motor 7 is started. The servo motor 7 drives the lead screw 8 to rotate. When the lead screw 8 rotates, it drives the movable slide 13 to move below the rivet head 3. The hydraulic rod 2 can drive the rivet head 3 to press the rivet into the workpiece. After pressing, the servo motor 7 moves the movable slide 13 out from under the rivet head 3, and the workpiece with the rivet pressed in can be taken out.
