Description

Technical Field

[0001] The utility model provides a metal pipe fitting end processing device, which relates to the technical field of pipe fitting processing. Background Art

[0002] A metal pipe is a pipe made of metal as raw material. Through different processing techniques, metal pipes can be made into metal fittings with different functions and applied in various fields of society, such as construction, machinery manufacturing, etc. When processing metal pipe fittings, operations such as cutting and grinding the ends are often required to ensure the flatness of the ends.

[0003] After retrieval, a Chinese patent with the authorization announcement number CN219444740U discloses a metal pipe fitting end processing device. By starting the servo cylinder, this utility model drives the push plate, sliding block, rotating frame one, rotating shaft, and rotating frame two to rotate in sequence, and then can adjust the height of the top plate to adapt to workers of different heights. At the same time, when clamping the pipe fitting, a bidirectional threaded rod is used to drive the threaded block to slide, and then drive the rotating rod to rotate, so that it can conveniently drive the clamping plates to slide towards the opposite sides to clamp and fix the metal pipe fitting.

[0004] Although the above patent solves the problem that the existing end processing device cannot be applicable to workers of different heights and can also clamp and fix the pipe fitting, in the actual use process, since the processing work on the end of the pipe fitting needs to operate on the entire circumference of the end, in the above patent, once the pipe fitting is clamped and fixed, the pipe fitting cannot rotate. For the processing of the bottom end of the pipe fitting end, the angle is rather tricky, and the operation is rather troublesome, which affects the work efficiency. Therefore, we propose a metal pipe fitting end processing device. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that the existing pipe fitting end processing device cannot rotate the pipe fitting, resulting in a tricky angle and troublesome operation during end processing.

The positioning mechanism includes a processing table fixedly connected to the top of the lifting mechanism, a frame fixedly connected to the top of the processing table, a positioning bottom plate and a positioning top plate arranged inside the frame. The positioning bottom plate is fixedly connected to the processing table. Positioning rollers are symmetrically arranged on the positioning bottom plate, and a driving component for driving the positioning rollers to rotate is arranged on one side of the positioning bottom plate. The positioning top plate has the same structure as the positioning bottom plate and is arranged oppositely. A hydraulic cylinder is fixedly connected to the top of the frame, and the telescopic end of the hydraulic cylinder penetrates the frame downward and is fixedly connected to the positioning top plate.

[0007] Preferably, mounting grooves adapted to the positioning rollers are formed on both the positioning bottom plate and the positioning top plate, and support blocks II are fixedly connected to both ends of the mounting grooves. Rotating shafts are fixedly connected to both ends of the positioning rollers, and the rotating shafts are rotatably connected to the support blocks II.

[0008] Preferably, the driving assembly includes a worm gear fixedly connected coaxially with the rotating shaft, a worm meshing below the worm gear, and a driving rod fixedly connected coaxially with the worm. The driving rod is rotatably connected to a support block I, and one end of the driving rod is connected to a driving motor. Both the driving motor and the support block I are fixedly connected to the side walls of the positioning bottom plate and the positioning top plate.

[0009] Preferably, the driving motor is a brake motor.

[0010] Preferably, anti-slip rubber strips are fixedly connected to the outer sides of the positioning rollers, and several groups of the anti-slip rubber strips are arranged circumferentially along the positioning rollers.

[0011] Preferably, the lifting mechanism is a scissor lift.

[0019] The preferred embodiments of the present utility model will be described in detail below with reference to the drawings.

[0020] Reference Figures 1 to 4 , the present utility model provides a metal pipe fitting end processing device, which includes a lifting mechanism 1 and a positioning mechanism arranged on the top of the lifting mechanism 1. The positioning mechanism includes a processing table 2 fixedly connected to the top of the lifting mechanism 1, a frame 4 fixedly connected to the top of the processing table 2, a positioning bottom plate 3 and a positioning top plate 6 arranged inside the frame 4. The positioning bottom plate 3 is fixedly connected to the processing table 2. Symmetrically arranged positioning rollers 7 are provided on the positioning bottom plate 3, and a driving assembly 8 for driving the positioning rollers 7 to rotate is arranged on one side of the positioning bottom plate 3. The positioning top plate 6 has the same structure as the positioning bottom plate 3 and is arranged oppositely. A hydraulic cylinder 5 is fixedly connected to the top of the frame 4. The telescopic end of the hydraulic cylinder 5 penetrates downward through the frame 4 and is fixedly connected to the positioning top plate 6. Specifically, the pipe fitting is placed on the positioning bottom plate 3, and the positioning top plate 6 is driven by the hydraulic cylinder 5 to move downward, so that the positioning top plate 6 and the positioning bottom plate 3 clamp and fix the pipe fitting together. When the pipe fitting needs to be rotated, the driving assembly 8 drives the positioning rollers 7 to rotate, and the positioning rollers 7 drive the pipe fitting to rotate, thus facilitating the processing of the pipe fitting end.

[0021] Furthermore, as shown in Figure 2 and Figure 3 , mounting grooves 9 matching the positioning rollers 7 are opened on both the positioning bottom plate 3 and the positioning top plate 6, and support blocks two 16 are fixedly connected to both ends of the mounting grooves 9. Rotating shafts 11 are fixedly connected to both ends of the positioning rollers 7, and the rotating shafts 11 are rotatably connected to the support blocks two 16. The support blocks two 16 play a supporting role for the positioning rollers 7. The driving assembly 8 includes a worm gear 10 fixedly connected coaxially with the rotating shaft 11, a worm 12 meshing below the worm gear 10, and a driving rod 13 fixedly connected coaxially with the worm 12. The driving rod 13 is rotatably connected to a support block one 14. One end of the driving rod 13 is connected to a driving motor 15. Both the driving motor 15 and the support block one 14 are fixedly connected to the side walls of the positioning bottom plate 3 and the positioning top plate 6. Specifically, the driving motor 15 is started, the driving motor 15 drives the driving rod 13 to rotate, the driving rod 13 drives the two worms 12 to rotate, the worms 12 drive the worm gears 10 to rotate, and the worm gears 10 drive the rotating shafts 11 to rotate, achieving the effect of driving the positioning rollers 7 to rotate.

[0022] Further, the drive motor 15 is a brake motor. Specifically, a brake motor is a motor equipped with an electromagnetic brake. When the motor is powered on, the electromagnetic brake is also powered on and attracted, and at this time it does not brake the motor. When the motor is powered off, it also loses power and brakes the motor, enabling the motor to have a self-locking function. Further, the helix angle of the worm 12 in the present utility model is smaller than the equivalent friction angle between the meshing teeth of the worm 12 and the worm wheel 10, so that the worm 12 and the worm wheel 10 can achieve the effect of self-locking, and double self-locking is achieved through the worm wheel 10, the worm 12, and the drive motor 15. When only the pipe fitting needs to be clamped and positioned, the positioning bottom plate 3 and the positioning top plate 6 clamp the pipe fitting. In fact, the four positioning rollers 7 limit the pipe fitting in four directions. Through double self-locking, the positioning rollers 7 will not rotate under the action of external force, thus ensuring the positioning effect.

[0023] Further, as Figure 4 shown, an anti-slip rubber strip 17 is fixedly connected to the outer side of the positioning roller 7, and several groups of the anti-slip rubber strips 17 are arranged along the circumferential direction of the positioning roller 7. Specifically, the friction between the positioning roller 7 and the pipe fitting is increased through the anti-slip rubber strip 17 to ensure that the positioning roller 7 can drive the pipe fitting to rotate.

[0024] Further, the lifting mechanism 1 is a scissor lift. The scissor lift is a known prior art to those skilled in the art, so its specific structure and working principle will not be described in detail.

[0025] Working principle: Place the pipe fitting on the positioning bottom plate 3, support the pipe fitting by the two positioning rollers 7 on the positioning bottom plate 3, drive the positioning top plate 6 to move downward by the hydraulic cylinder 5, so that the two positioning rollers 7 on the positioning top plate 6 gradually press on the top of the pipe fitting, thereby clamping and fixing the pipe fitting. When the pipe fitting needs to be rotated, start the drive motor 15 to drive the positioning roller 7 to rotate, and drive the pipe fitting to rotate through the positioning roller 7, so as to facilitate the processing of the end of the pipe fitting.

[0026] The above describes the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative purpose of the present utility model, they should all fall within the protection scope of the present utility model.
