Description

Technical Field

[0001] The invention relates to the field of tapping equipment, and in particular to high-speed tapping equipment. Background Art

[0002] A tapping machine is a special equipment that can perform tapping processing on products. The working principle of a traditional tapping machine is: control the rotating tap to descend, extend it into the opening on the product to tap, so that the internal thread is tapped in the hole. After the tapping is completed, in order to separate the tap from the product, it is necessary to control the tap to rotate in the opposite direction and rise, so that the tap can reverse and withdraw along the previously tapped internal thread. The problems existing in the actual tapping operation using the above method are: 1. The chips remaining at the end of the thread are easy to cause the cutting edge to crack when the tap reverses and withdraws, and even cause the tap to break; 2. Reversing will cause the non-turning tool blade to cut the thread, causing the thread to be squeezed and deformed, affecting the thread quality, and the tap is reversed and withdrawn without aligning with the eyelet, which may cause the threaded hole to tilt, affecting the quality and stability of the thread; 3. The time required for the tap to retract is relatively long, and high-speed tapping operations cannot be achieved. Summary of the invention

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide a high-speed tapping device for solving the above-mentioned problems.

Send the product to be tapped to the bottom of the tap; S2. The chuck component drives the tap to rotate and move downward, and the tap performs tapping processing on the product to be tapped from top to bottom; S3. When the tapping process is completed and the working part of the tap completely passes through the product, the chuck component releases the clamping of the tap, the tap falls, and the shank of the tap also completely passes through the product. A clamping component is provided under the product to position and clamp the tap; S4. The tapped product is then removed, and the clamping assembly moves up with the tap, so that the shank of the tap re-enters the chuck component and is clamped by the chuck component. After the above actions are completed, the product to be tapped is again sent to the bottom of the tap, and the cycle continues.

[0005] In step S2, the chuck component is a magnet, and the magnet adsorbs the top end of the tap, thereby achieving the upper and lower positioning of the tap.

When the tapping operation is performed, the chuck component can realize the positioning of the upper and lower positions of the tap, so that the tap and the first lifting seat are lifted and lowered synchronously. When the tapping operation is completed, the chuck component is separated from the tap, and the tap falls through the threaded hole tapped on the product and rests on the base. A clamping component is also arranged above the corresponding base, and the clamping component is arranged on the second lifting seat. The clamping component can position and clamp the tap.

[0007] The first lifting seat is connected with a slide seat, the frame is provided with a slide rail matched with the slide seat, the first lifting seat is screwed with a driving screw rod, and the driving screw rod is connected with the output end of the first motor.

[0008] It also includes a feeding component, which includes a feeding channel. A material picking robot is arranged corresponding to the feeding channel. The material picking robot can send the product on the feeding channel to a placement seat, and the placement seat is arranged on a moving seat.

[0009] The material-grabbing robot includes a first moving frame, which is connected to the piston rod of the first cylinder, on which a first lifting frame is movably arranged, which is connected to the piston rod of the second cylinder, which is arranged on the first moving frame, and on which a first clamping cylinder is arranged.

[0011] The chuck component comprises a magnet, which is arranged in the first lifting seat and can attract the tap inserted into the rotating sleeve.

[0012] By adopting the above technical solution, the beneficial effect achieved is: after the tap completes the tapping process, the tap can fall naturally and pass through the threaded hole tapped on the product, thereby realizing rapid separation of the tap from the product, without the need to reverse and retract the tap, thereby avoiding damage to the threaded hole and the tap, and effectively improving the tapping quality and the service life of the tap; at the same time, the time required for the overall tapping is greatly reduced, thereby realizing rapid tapping operations and improving the efficiency of the tapping process.
