[0018] The technical scheme in the embodiments of the utility model will be further clearly and completely explained in detail in combination with the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0019] As Figs. 1-2As shown, a welding tool integrated automatic hole opening system includes a welding tool 1, a fixed mounting base 7 is arranged at a corresponding hole opening position of the welding tool 1, a side-mounted motor lead screw module 4 is mounted on the fixed mounting base 7, the side-mounted motor lead screw module 4 includes a lead screw and a servo motor 5, the servo motor 5 drives the lead screw to rotate, a hole opening motor 6 is mounted on the lead screw, the servo motor 5 drives the hole opening motor 6 to lift, a waste collecting cylinder 8 is mounted on the side of the hole opening motor 6.

[0020] The lead screw is mounted on the welding tool 1 through a bearing seat, a driven gear is mounted on the lower part of the lead screw, the driven gear is connected to a driving gear through a chain or a gear box, and the driving gear is mounted on the motor shaft of the servo motor 5.

[0021] A screw nut seat 11 is mounted on the lead screw, the hole opening motor 6 is mounted on the screw nut seat 11, a waste collecting cover 9 is mounted on the upper part of the hole opening motor 6, and the waste collecting cover 9 collects iron filings in the punching process.

[0022] The waste collecting cylinder 8 is mounted on the welding tool, a magnet is mounted on the cylinder rod end of the waste collecting cylinder 8, and the waste collecting cylinder magnet is close to the waste collecting cover to absorb iron filings.

[0023] A control box 3 is mounted on the welding tool, a motion controller 2 is mounted on the upper part of the control box, the motion controller 2 is linearly connected to a control button box 10, and the control button box 10 is mounted on the outside of the welding tool 1.

[0024] The motion controller 2 is linearly connected to the servo motor 5 and the hole opening motor 6, and the motion controller 2 controls the actions of the servo motor 5 and the hole opening motor 6.

[0025] Since the distance between the part and the welding tool platform is only 500 mm, in order to ensure that the installation size of the punching mechanism can be put into the distance between the part and the welding platform, a side-mounted motor lead screw module is used to reduce the overall length. Since the part hole opening plane is not parallel to the welding tool bottom plate, in order to ensure that the hole opener is parallel to the punching plane, the fixed base can be angle-adjusted to ensure that the hole opener is perpendicular to the part. During the welding process of the part, the motion controller, the side-mounted motor lead screw module and the servo motor cooperate to control the hole opening motor to perform automatic hole opening operation. At the same time, the waste sheet collecting cylinder and the waste collecting cover can automatically collect the hole opening iron filings and the hole opening waste sheets.

[0026] Further description: The machining process needs to be performed on a 1.5 mm thick carbon steel plate to perform a 35 mm diameter hole opening operation, and a hole opener needs to be used. The hole opener first drills a 4 mm positioning hole, and then performs a 35 mm diameter hole opening operation. The feeding speeds of the two processes are different, and the feeding speed can be accurately controlled through the motion controller.

[0027] In order to ensure that the hole opening of the hole opener is successfully completed, the rotation speed of the hole opening motor is reasonably selected and determined through repeated tests.

[0028] Iron filings collection cover is installed below the trepanning machine, with a diameter of 125mm and a depth of 70mm, and a bearing with a diameter of 10mm in the middle. At the beginning of the trepanning machine operation, the iron filings collection cover rotates with the trepanning machine, and stops rotating when it contacts the surface of the part. The iron filings during the trepanning process will fall into the collection cover, avoiding scattering everywhere.

[0029] During the trepanning process, a circular waste piece with a diameter of about 32mm will be formed. Because the part is punched in the welding tool, the welded part will form a cavity, and the waste piece cannot be taken out directly after falling into the cavity. There is a hole with a diameter of 40mm at the rear of the part, and a waste piece collection cylinder is installed, and a permanent magnet is fixed at the front end of the cylinder rod. During the trepanning process, the controller controls the cylinder to extend above the trepanning machine. After the trepanning machine completes the trepanning, it continues to feed to a position 5mm away from the permanent magnet, and the strong magnet will attract the waste piece, and the trepanning machine will return to the original position at high speed. The waste piece collection cylinder sucks the waste piece to retract, so as to take out the waste piece from the cavity.

[0030] When the part is positioned and clamped by the welding tool clamp during trepanning, the whole operation process can be automatically completed by pressing the start button after the part is clamped in place.

[0031] The utility model is not limited to the above-mentioned embodiment, anyone should know the structural change made under the inspiration of the utility model, any technical scheme with the same or similar as the utility model falls into the protection scope of the utility model.

[0032] The technical, shape and structure parts not described in detail in the utility model are well-known technologies.
