Description

Automatic nail feeding riveting machine and its operation method

technical field

The invention relates to a screw riveting device, in particular to an automatic nail feeding riveting machine and an operation method thereof.

Background technique

The casing of the existing monitoring equipment requires pressure riveting screws. At present, manual assembly is usually used to manually insert the screws into the nailing positions one by one, and then the pressure riveting head is used to force the screws. However, 10 to 20 screws usually need to be installed on each workpiece, and some have even more. Manual assembly takes a long time, is inefficient, and is easy to miss. In addition, the manual assembly method requires all the screws to be installed before pressure riveting. During the pressure riveting process, vibrations and unstable clamping are likely to occur, which may easily cause the screws after pressure riveting to tilt, and the production quality is low. This type of screw has a small diameter, and the existing manipulator cannot grasp the screw with a small diameter, nor can it ensure that the axis of the screw is inserted into the nailing position without tilting.

Contents of the invention

The present invention mainly aims at the above problems, and provides an automatic nail-feeding riveting machine and its operating method which can effectively replace manual nailing, save manpower, improve riveting efficiency and accuracy, and improve production quality.

The purpose of the present invention is mainly achieved through the following scheme: an automatic nail feeding riveting machine, including a frame, the bottom of the frame is provided with a working platform that can move horizontally, horizontally and vertically, and There is a riveting head and a nailing mechanism, and a positioning sleeve is installed on the nailing mechanism. At least one vibrating discharge machine is installed on the side of the frame. One end of the discharge machine is connected with the positioning sleeve. The frame is equipped with a riveting head and a nailing mechanism, and the screws are put into the vibrating unloading machine, which can transport the screws one by one to the nailing mechanism through the nail feeding tube, and use the nailing mechanism to receive the screws. The working platform drives the workpiece to translate horizontally and vertically on the horizontal plane, so that the nailing position of the workpiece corresponds coaxially with the positioning sleeve on the nailing mechanism. The positioning sleeve can guide the screw so that the screw falls vertically into the nailing position, and then the working platform can be used Drive the workpiece to move, so that the position where the screw is installed is coaxial with the riveting head, and start the riveting head to complete the riveting of the screw. Then drive the workpiece to move through the working platform, so that the next nailing position corresponds to the coaxial position of the positioning sleeve, and repeat the above actions. During the whole process, one screw is installed and one screw is pressure riveted, so as to avoid the impact on the accuracy of other screws after the nails are installed at the same time, the overall production quality is improved by the way of installing one and pressing one, and the positioning sleeve is used to guide the screw. To ensure the accuracy of screw assembly, the use of CNC mobile working platform can ensure the precise positioning of the nailing position, positioning sleeve and pressure riveting head, without manual nailing, and improve production efficiency.

As a preference, the side of the positioning sleeve is provided with a nail cutting mechanism for alternately cutting off the flow of the positioning sleeve. The nail cutting mechanism includes a driving cylinder, an alternating rod, a first nail cutting rod hinged with the upper end of the alternate rod and a hinged joint with the lower end of the alternate rod. For the second nail rod, the side of the positioning sleeve is provided with an articulated arm, the middle part of the alternate rod is hinged with the hinge arm, the piston rod of the driving cylinder is hinged with the end of the alternate rod close to the second nail rod, and the first nail rod passes through the first guide The hole runs through the outer wall of the positioning sleeve, the second stapler rod passes through the outer wall of the positioning sleeve through the second guide hole, and the length of the first stapler rod is greater than that of the second stapler rod. The nail-cutting mechanism includes a drive cylinder, an alternate rod, a first nail-cut rod hinged to the upper end of the alternate rod, and a second nail-cut rod hinged to the lower end of the alternate rod. Realize that the upper and lower ends of the alternate rod swing in different directions. The driving cylinder pushes the piston rod so that the piston rod advances toward the axis of the positioning sleeve, and the lower end of the alternate rod swings toward the axis of the positioning sleeve, and then pushes the second staple rod toward the axis of the positioning sleeve and penetrates the second guide hole to catch the screw at the bottom end , to achieve the closure of the screw. When the working platform drives the workpiece to move so that the nailing position corresponds to the coaxial position of the positioning sleeve, the driving cylinder pushes the piston rod to shrink away from the axis of the positioning sleeve, and the lower end of the alternating rod swings away from the axis of the positioning sleeve, thereby driving the second staple rod away from the axis of the positioning sleeve. The axis of the positioning sleeve is not separated from the screw at the bottom end, and the screw at the bottom end falls into the nailing position of the workpiece. At the same time, the upper end of the alternating rod pushes the first nail clipping rod to swing toward the axis of the positioning sleeve. Because the first nail clipping rod The length is greater than the length of the second nail bar, and when the alternate bar is at the critical point of the vertical state, that is, before the second nail bar breaks away from the screw at the lowermost end, the first nail bar has passed through the first guide hole to the bottom A screw limit above the lower end screw is stuck, so that the screws can fall alternately. During the riveting process of the riveting head, the piston of the driving cylinder should advance toward the axis of the positioning sleeve, and the upper end of the alternate rod swings away from the axis of the positioning sleeve, driving the first nail rod away from the screw. At the same time, the lower end of the alternate rod moves toward the positioning sleeve. Swing in the axial direction of the sleeve, driving the second nail rod to pass through the second guide hole. When the first nail rod is separated from the screw, the screw automatically falls to the second nail rod and is limited by the second nail rod. Installation of the next staple position. When the screws fall into the binding position, when the riveting is performed, and when the work is repeated, the screws are guaranteed to be placed alternately to prevent the screws from falling completely due to gravity, and to ensure that the screw delivery tube is full of screws, shortening the waiting time for screw delivery and further improving efficiency.

Preferably, the first guide hole and the second guide hole are both frustum holes, and the diameter of the end of the first guide hole and the second guide hole away from the axis of the positioning sleeve is larger than the diameter of the end close to the axis of the positioning sleeve.
