Description

Technical Field

[0001] This utility model relates to a mechanical tee tapping device, belonging to the technical field of machining equipment. Background Technology

[0002] A mechanical tee is a type of pipe connector. It is made by drilling a hole in a straight pipe and then inserting the tee into the hole. The hole is then sealed around the pipe wall by a sealing ring.

[0003] Existing mechanical tees, as shown in the attached document. Figure 1 As shown, it includes a half tile, with fixing blocks 12 fixed to both sides of the half tile. The fixing blocks 12 are respectively provided with through holes 13. The half tile is provided with an inner sealing ring platform 11, and a threaded hole 14 is machined on the top of the inner sealing ring platform 11.

[0004] Traditional tapping machines for machining mechanical tees typically can only clamp and process one workpiece at a time. The clamping, tapping, and unclamping steps must be performed sequentially, resulting in significant waiting time and low overall efficiency. Traditional tapping requires manual clamping, which can lead to uneven clamping force. Excessive clamping force can damage thin-walled fixing blocks, while insufficient clamping force can cause the workpiece to loosen during machining, resulting in broken taps or damaged threads. Furthermore, vibrations during the tapping process can easily cause clamping failure.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] To address the shortcomings of the prior art, this utility model provides a mechanical three-way tapping device that can efficiently switch between two workstations, significantly improving production efficiency. It can also automatically and flexibly clamp the workpiece to prevent it from loosening during the tapping process.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: A mechanical tee tapping device includes a support and positioning mechanism, a tapping mechanism mounted above the support and positioning mechanism, and a clamping mechanism at the bottom of the tapping mechanism. The support and positioning mechanism includes a base plate, two positioning plates arranged side by side mounted on the base plate, and a positioning post fixedly mounted on each positioning plate. The positioning post has a circular positioning hole inside, and positioning pins are respectively provided on the left and right sides of the positioning post. The tapping mechanism includes a motor, and the output shaft of the motor is connected to a longitudinally arranged tap through a tap chuck. The clamping mechanism includes two spring telescopic rods arranged side by side, and a pressure head is respectively mounted on the bottom end of each spring telescopic rod.

[0008] Furthermore, the positioning plate and the base plate are connected by an adjustment tube set in the vertical direction.

[0009] Furthermore, the positioning post has a semi-cylindrical structure.

[0010] Furthermore, the positioning holes are set longitudinally through the positioning post and positioning plate.

[0011] Furthermore, the locating pin is mounted on the locating plate along the longitudinal thread.

[0012] Furthermore, the motor is fixedly mounted on top of the mounting plate, which is then fixedly connected to the bottom end of the vertical telescopic cylinder.

[0013] Furthermore, the vertical telescopic cylinder is mounted on a horizontally arranged slide rail via a slider, and the side of the slider can be connected to the horizontally arranged telescopic cylinder.

[0014] Furthermore, the top of the spring telescopic rod is fixed to the bottom of the mounting plate.

[0015] Furthermore, two spring telescopic rods are distributed on both sides of the tap.

[0016] Furthermore, the spring telescopic rod includes an inner rod and an outer rod that are slidably connected, and a compression spring is sleeved on the main body of the inner rod and the outer rod.

[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: This utility model adopts a dual-station design, with two side-by-side positioning units for the support and positioning mechanism. The tapping / clamping mechanism can move horizontally and switch between the two stations, greatly improving production efficiency. This invention employs a unique spring telescopic rod for flexible clamping, generating a continuous, stable, and adaptive downward clamping force during the tapping process. This effectively resists tapping vibrations, prevents workpiece loosening, and protects the tap. The combination of positioning holes and positioning pins ensures that the mechanical tee is accurately and reliably positioned before processing, laying the foundation for high-quality tapping.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0021] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0022] like Figure 1 As shown, the mechanical tee 1 in the prior art includes a half-span, with fixing blocks 12 fixed to both sides of the half-span, and through holes 13 respectively opened on the fixing blocks 12. An inner sealing ring platform 11 is provided inside the half-span, and a threaded hole 14 is machined above the inner sealing ring platform 11.

[0023] like Figures 2-5 As shown in the figure, this utility model provides a mechanical tee tapping device, including a support and positioning mechanism 2, a tapping mechanism 3 installed above the support and positioning mechanism 2, and a pressing mechanism 4 provided at the bottom of the tapping mechanism 3. The pressing mechanism 4 can press the mechanical tee 1 onto the support and positioning mechanism 2.

[0024] The support and positioning mechanism 2 includes a base plate 21, and two positioning plates 22 arranged side by side are installed on the top of the base plate 21. The positioning plates 22 are connected to the base plate 21 by an adjustment tube 23 arranged in the vertical direction.

[0025] Positioning posts 24 are fixedly installed on the top of each positioning plate 22. The positioning posts 24 are semi-cylindrical structures, and each positioning post 24 has a circular positioning hole 25 inside. The positioning hole 25 is set longitudinally through the positioning post 24 and the positioning plate 22. The positioning hole 25 is used for longitudinal insertion of the inner sealing ring platform 11 to achieve positioning.

[0026] Positioning pins 26 are respectively provided on the left and right sides of the positioning post 24, and the positioning pins 26 are threadedly installed on the positioning plate 22 along the longitudinal direction. The positioning pins 26 are used to fit into the through hole 13 of the fixing block 12 to position the fixing block 12.

[0027] The tapping mechanism 3 includes a motor 32, which is fixedly installed above the mounting plate 34. The output shaft of the motor 32 is connected to a longitudinally arranged tap 31 through a tap chuck, and the motor 32 drives the tap 31 to rotate.

[0028] The mounting plate 35 is fixed to the bottom end of the vertical telescopic cylinder 33, which provides power for the lifting and lowering of the mounting plate 34.

[0029] The vertical telescopic cylinder 33 is mounted on the horizontally arranged slide rail 36 via a slider 35. The side of the slider 35 can be connected to the horizontally arranged telescopic cylinder. The horizontally arranged telescopic cylinder provides power for the vertical telescopic cylinder 33 to move left and right along the slide rail 36. The left and right movement of the vertical telescopic cylinder 33 realizes the switching between the two tapping stations (the horizontally arranged telescopic cylinder is not shown in the figure).

[0030] The clamping mechanism 4 includes two spring telescopic rods 41 arranged side by side, distributed on both sides of the tap 31, with the top ends of the spring telescopic rods 41 fixed to the bottom of the mounting plate 34, and pressure heads 42 respectively installed at the bottom ends of the spring telescopic rods 41. The pressure heads 42 are used to press the fixing block 12 of the mechanical tee 1 onto the positioning pin 26.

[0031] The spring telescopic rod 41 includes an inner rod and an outer rod that are slidably connected, and a compression spring is sleeved on the main body of the inner rod and the outer rod.

[0032] The specific working process of this utility model: Workpiece clamping: Place the mechanical tee 1 that needs to be tapped on the support and positioning mechanism 2, insert the inner sealing ring platform 11 longitudinally into the positioning hole 25 inside the positioning column 24, and fit the through hole 13 on the fixing block 12 onto the positioning pin 26 of the corresponding station.

[0033] The clamping mechanism descends and clamps: The vertical telescopic cylinder 33 drives the mounting plate 34 at its bottom to move downwards. The mounting plate 34 drives the motor 32, tap 31 and clamping mechanism 4 to descend together. When the pressure head 42 contacts the upper surface of the fixed block 12, the spring telescopic rod 41 starts to work. The spring is compressed to generate a continuous and flexible downward pressure, which firmly clamps the fixed block 12 onto the positioning pin 26, ensuring that the mechanical tee 1 maintains a stable clamping force throughout the tapping process.

[0034] Tapping action: While the clamping mechanism 4 stably presses down the mechanical tee 1, the motor 32 starts. The motor 32 drives the tap 31 to rotate at high speed through the tap chuck. At the same time as the tap rotates, the vertical telescopic cylinder 33 continues to drive the mounting plate 34 downward, so that the rotating tap 31 feeds vertically downward, thus achieving tapping.

[0035] This utility model adopts a dual-station design, with two side-by-side positioning units (positioning column + positioning pin) supporting the positioning mechanism. The tapping / clamping mechanism can move horizontally to switch between the two stations, improving efficiency.

The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
