Its structure usually includes spindle, feed mechanism, workpiece clamping device and other parts, can realize the processing process of automation or semi-automation. In the use process, operator only needs to fix workpiece on machine tool, selects appropriate tap and processing parameter, can start processing. In addition, tapping machine is also suitable for various scale workpiece processing, from small parts to large components can be handled easily. In mechanical manufacturing, automobile manufacturing, aerospace and other fields, tapping machine plays an important role.

[0003] Device base is usually designed as rectangular shape, in order to ensure the stability and safety of device base, must accurately process thread hole at four corners of base. The role of these thread holes is to be able to firmly fix equipment in proper position by bolt. During processing, first, device base is firmly fixed on appropriate workbench by using clamp to prevent device base from moving or vibrating during processing. Then, operator uses tapping machine to process first thread hole on one corner of device base. After processing one thread hole, clamp position needs to be repeatedly loosened and adjusted to ensure that corresponding thread holes can be accurately processed on other three corners of base. Since this process involves multiple loosening and position adjustment of clamp, the whole processing speed is relatively slow. Therefore, a double-station tapping machine is proposed. UTILITY MODEL CONTENTS

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this application, the worm gear can be rotated by operating the handwheel. The rotation of the worm gear drives the worm wheel, which in turn causes the movable shaft to rotate. The rotation of the movable shaft drives the rotation of the rotating plate, which in turn causes the equipment housing on the sliding frame to rotate.

During this process, the movement of the sliding block drives the equipment housing to displace along the adjusting screw axis, thereby adjusting the distance between the tap bodies. This mechanism facilitates the machining of threaded holes on rectangular equipment bases of different sizes. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a dual-station tapping machine, including a machine housing 1, a drive motor 2 fixedly installed inside the machine housing 1, a tap clamp 3 fixedly installed at the output end of the drive motor 2, a tap body 4 connected to the tap clamp 3, an adjustment mechanism 6 connected to the machine housing 1, and a rotating mechanism 5 provided below the sliding frame 601. By cooperating with the adjustment mechanism 6 and the rotating mechanism 5, threaded holes can be machined on rectangular machine bases of different sizes.

[0022] like Figure 2 and Figure 3As shown, the rotating mechanism 5 includes a positioning bracket 501 disposed below the sliding frame 601. A movable shaft 503 is rotatably mounted on the positioning bracket 501. A rotating plate 502 is fixedly mounted on the upper end of the movable shaft 503. A worm gear 504 is fixedly mounted on the lower end of the movable shaft 503. A worm 506 is rotatably mounted on one side of the worm gear 504. A handwheel 505 is connected to the end of the worm 506. A protective shell 507 is fixedly mounted on the bottom of the positioning bracket 501. A rotating slip ring is provided on the positioning bracket 501. The rotating plate 502 is rotatably mounted on the positioning bracket 501 through the rotating slip ring.

[0023] Specifically, the rotation of handwheel 505 is transmitted to worm gear 506, and the rotation of worm gear 506 is further transmitted to worm wheel 504, causing worm wheel 504 to also begin to rotate. The rotation of worm wheel 504 is then transmitted to movable shaft 503, causing movable shaft 503 to begin to rotate. The rotation of movable shaft 503 drives the rotation of rotating plate 502, and the rotation of rotating plate 502 is transmitted to the equipment housing 1 on sliding frame 601, causing it to begin to rotate. The rotation of equipment housing 1 ultimately causes tap body 4 to align sequentially with the holes at the four corners of rectangular equipment base. This precise alignment process greatly facilitates thread machining within the holes at the four corners of the rectangular equipment base, improving machining efficiency and accuracy.

[0024] like Figure 2 and Figure 4 As shown, the adjustment mechanism 6 includes a sliding frame 601 connected to the equipment housing 1. A fixed frame 606 is fixedly installed in the middle of the sliding frame 601. A servo motor 608 is fixedly installed on the fixed frame 606. An adjustment screw 603 is rotatably installed above the sliding frame 601. A screw nut 605 is provided on the adjustment screw 603. A sliding block 604 is provided on the screw nut 605, and the sliding block 604 is fixedly installed on the equipment housing 1. A retainer 602 is provided on the sliding frame 601. A helical gear 607 is provided at the output end of the servo motor 608 and the end of the adjustment screw 603, and the helical gear 607 meshes with each other. A sliding groove is provided inside the sliding frame 601, and the equipment housing 1 is movably installed inside the sliding frame 601 through the sliding groove.

[0025] Specifically, when the servo motor 608 is started, it begins to rotate, driving the helical gear 607 to rotate as well. The rotational motion of the helical gear 607 is transmitted to the adjusting screw 603, causing it to rotate as well. As the adjusting screw 603 rotates, the sliding block 604 on the screw nut 605 moves along the axial direction of the adjusting screw 603. During this movement, the sliding block 604 further pushes the device housing 1 to move along the axial direction of the adjusting screw 603. This series of mechanical movements ultimately achieves the adjustment of the distance between the tap bodies 4, enabling the device to adapt to rectangular device bases of different sizes, thereby precisely machining the required threaded holes on these bases.

[0026] Working principle: The positioning bracket 501 is installed on the lifting device. During processing, the rectangular equipment base is placed below the tap body 4. Placing the rectangular equipment base below the tap body 4 activates the servo motor 608. Activating the servo motor 608 drives the helical gear 607 to rotate. The rotation of the helical gear 607 then drives the adjusting screw 603 to rotate. The rotation of the adjusting screw 603 causes the sliding block 604 on the screw nut 605 to move along the adjusting screw 603. During the movement of the sliding block 604, the equipment housing 1 moves axially along the adjusting screw 603, thereby adjusting the distance between the tap bodies 4. This aligns the two tap bodies 4 with the holes at opposite corners of the rectangular equipment base. After adjustment, the... The tap body 4 is rotated by the drive motor 2, thereby machining threads in the holes at the diagonal positions of the rectangular equipment base. After that, the tap body 4 can be retracted. After retracting the tap body 4, the handwheel 505 can be turned. Turning the handwheel 505 will drive the worm gear 506 to rotate. After the worm gear 506 rotates, it will drive the worm wheel 504 to rotate. After the worm wheel 504 rotates, it will drive the movable shaft 503 to rotate. After the movable shaft 503 rotates, it will drive the rotating plate 502 to rotate. After the rotating plate 502 rotates, it will drive the equipment housing 1 on the sliding frame 601 to rotate, so that the tap body 4 is aligned with the hole on another mating line on the rectangular equipment base, which facilitates machining threads in the holes at the four corners of the rectangular equipment base.
