Description

Technical Field

[0001] The present invention relates to the technical field of pipe fitting grinding, and particularly to a small stainless steel pipe fitting grinding device. Background Art

[0002] Stainless steel pipe fittings are pipe connectors made of stainless steel, mainly including types such as elbows, tees, crosses, reducing pipes, pipe caps, etc. They can be divided into four categories according to the connection method: socket type, threaded type, flanged type, and welded type.

[0003] However, in the prior art, in order to reduce the resistance of the inner wall of stainless steel pipe fittings to fluid, generally, the inner wall of stainless steel pipe fittings is polished to make its inner wall smooth. For some small stainless steel pipe fittings, their own pipe diameters are small, and due to the relatively simple structure of some grinding devices, it is very difficult to grind the deep part of the inner wall of stainless steel pipe fittings, and the grinding effect is poor. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages existing in the prior art: for some small stainless steel pipe fittings, their own pipe diameters are small, and due to the relatively simple structure of some grinding devices, it is very difficult to grind the deep part of the inner wall of stainless steel pipe fittings, and the grinding effect is poor.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solution: a small stainless steel pipe fitting grinding device, including a processing base. At both the left and right ends of the upper surface of the processing base, support vertical rods are fixedly connected. One end of the support vertical rod is fixedly connected with a clamp, and a stainless steel pipe fitting body is clamped and fixed on the surface of the clamp. A bolt is threadedly connected to the surface of the clamp near its opening end. At the center of the upper surface of the processing base, a first motor is fixedly connected. The output end of the first motor is fixedly connected with a rotating shaft, and one end of the rotating shaft is fixedly connected with a gear. Both the front and rear sides of the gear are meshed and connected with rack plates. The lower end of the rack plate is fixedly connected with a T-shaped slider, and the T-shaped slider is slidably connected with the processing base. One end of the rack plate is fixedly connected with a vertical plate, and on one side of the vertical plate, a second motor is fixedly connected. The output end of the second motor is fixedly connected with an output shaft, and the output shaft penetrates through the vertical plate. One end of the output shaft is fixedly connected with a grinding head.

[0006] As a preferred implementation manner, anti-slip textures are provided on the inner surface of the clamp.

[0007] As a preferred implementation manner, one end of the bolt is threadedly connected with a nut.

[0008] As a preferred implementation manner, brackets are fixedly connected to both sides of the lower end of the vertical plate, and support rollers are rotatably connected to the lower ends of the brackets.

[0009] As a preferred embodiment, a pressure sensor is fixedly connected to the lower end of the vertical plate at a position between the brackets. One side of the processing base is fixedly connected with a controller, and the controller is electrically connected to the first motor, the second motor and the pressure sensor.

[0010] As a preferred embodiment, a side block is fixedly connected to one end of the toothed plate away from the vertical plate, and limiting blocks are fixedly connected to the front and rear sides of the upper surface of the processing base near the gear.

[0011] As a preferred embodiment, the size of the grinding head is adapted to the size of the inner circle of the stainless steel pipe fitting body.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0013] In the present invention, with the help of the clamp and bolts, the stainless steel pipe fitting body is fixed above the processing base. With the help of the first motor, the rotating shaft and the gear, the front and rear toothed plates and the T-shaped sliders are driven to slide left and right relative to each other, so that the vertical plates on both sides gradually move towards the ports on both sides of the stainless steel pipe fitting body, facilitating the movement of the output shaft and the grinding head on the second motor deep into the inner wall of the stainless steel pipe fitting body. When the grinding head moves deep into the inner wall of the stainless steel pipe fitting body, the output shaft and the grinding head are driven to rotate by the second motor, thereby grinding the inner wall of the stainless steel pipe fitting body, so as to achieve the effect of facilitating the grinding of the deep part of the inner wall of the stainless steel pipe fitting body.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1

[0023] As Figures 1-5As shown in the figure, the present invention provides a technical solution: a small stainless steel pipe fitting grinding device, including a processing base 1. At the left and right ends of the upper surface of the processing base 1, support vertical rods 2 are fixedly connected. The support vertical rods 2 play a role in supporting the stainless steel pipe fitting body 4 fixed on the clamp 3. One end of the support vertical rod 2 is fixedly connected to a clamp 3, and the stainless steel pipe fitting body 4 is clamped and fixed on the surface of the clamp 3. A bolt 5 is threadedly connected to the surface of the clamp 3 near its opening end. Open the opening of the clamp 3, then place the stainless steel pipe fitting body 4 on the inner surface of the clamp 3, and then install the bolt 5 at the opening end of the clamp 3. When the bolt 5 is gradually tightened on the clamp 3, the open opening of the clamp 3 gradually becomes smaller and clamps and fixes the stainless steel pipe fitting body 4. At the center of the upper surface of the processing base 1, a first motor 7 is fixedly connected. The output end of the first motor 7 is fixedly connected to a rotating shaft 8, and one end of the rotating shaft 8 is fixedly connected to a gear 9. The front and rear sides of the gear 9 are meshed with a rack 10. By driving the rotation of the rotating shaft 8 and the gear 9 by the first motor 7, when the gear 9 rotates, it will drive the front and rear racks 10 to slide left and right relative to each other. The lower end of the rack 10 is fixedly connected to a T-shaped slider 11, and the T-shaped slider 11 is slidably connected to the processing base 1. With the help of the T-shaped slider 11, the stability of the linear sliding of the rack 10 on the processing base 1 is effectively improved. One end of the rack 10 is fixedly connected to a vertical plate 12, and a second motor 13 is fixedly connected to one side of the vertical plate 12. The output end of the second motor 13 is fixedly connected to an output shaft 14, and the output shaft 14 penetrates through the vertical plate 12. One end of the output shaft 14 is fixedly connected to a grinding head 15. When the stainless steel pipe fitting body 4 is clamped and fixed on the clamp 3, the grinding work on the inner wall of the stainless steel pipe fitting body 4 can be carried out next. With the help of the first motor 7, the rotating shaft 8 and the gear 9, the front and rear racks 10 and the T-shaped sliders 11 are driven to slide left and right relative to each other, so that the two vertical plates 12 gradually move towards the ports on both sides of the stainless steel pipe fitting body 4, facilitating the movement of the output shaft 14 and the grinding head 15 on the second motor 13 deep into the inner wall of the stainless steel pipe fitting body 4. When the grinding head 15 moves deep into the inner wall of the stainless steel pipe fitting body 4, the second motor 13 drives the output shaft 14 and the grinding head 15 to rotate, thereby grinding the inner wall of the stainless steel pipe fitting body 4, thus achieving the effect of facilitating the grinding of the deep part of the inner wall of the stainless steel pipe fitting body 4.

[0024] Embodiment 2

[0025] As Figures 1-5As shown, anti-slip textures are provided on the inner surface of the clamp 3. The setting of the anti-slip textures can increase the friction of the inner surface of the clamp 3, thereby effectively improving the stability of the clamp 3 when clamping and fixing the stainless steel pipe fitting body 4. One end of the bolt 5 is threadedly connected with a nut 6. By installing the nut 6 at one end of the bolt 5, the nut 6 and one end of the bolt 5 clamp the open end of the clamp 3, thereby further ensuring the tightness when the open end of the clamp 3 is closed and maintaining the stable clamping of the clamp 3 on the stainless steel pipe fitting body 4. Brackets are fixedly connected to both sides at the lower end of the vertical plate 12, and a support roller 16 is rotatably connected to the lower end of the bracket. With the help of the bracket and the support roller 16, the suspended lower end of the vertical plate 12 is supported, reducing the situation of its dropping at one end of the toothed plate 10. When the toothed plate 10 drives the vertical plate 12 to move, the support roller 16 will also roll accordingly, so that while supporting the vertical plate 12, it will not increase the resistance to the movement of the vertical plate 12, thus ensuring that the vertical plate 12 can move stably. A pressure sensor 17 is fixedly connected to the position between the brackets at the lower end of the vertical plate 12. One side of the processing base 1 is fixedly connected with a controller 18, and the controller 18 is electrically connected to the first motor 7, the second motor 13 and the pressure sensor 17. When the two grinding heads 15 inside the stainless steel pipe fitting body 4 come into contact, the pressure sensor 17 will collide with the side of the processing base 1 due to the movement of the vertical plate 12. At this time, the pressure information generated by the pressure sensor 17 under pressure will be transmitted to the controller 18. After receiving and analyzing the data, the controller 18 will automatically control the first motor 7 to change its rotation direction, making the rotating shaft 8 and the gear 9 perform reverse rotational movements compared to before, thereby making the two toothed plates 10 change their movement directions and move towards the outside of the processing base 1, so that the grinding heads 15 move towards the outlet end of the stainless steel pipe fitting body 4, completing a grinding operation. Through the cooperation of the pressure sensor 17 and the controller 18, the operation steps of the staff during the inner wall grinding of the stainless steel pipe fitting body 4 are reduced, so that there is no need to manually change the rotation direction of the first motor 7, simplifying the operation steps. A side block 19 is fixedly connected to the end of the toothed plate 10 far away from the vertical plate 12. Limit blocks 20 are fixedly connected to the upper surface of the processing base 1 near the front and rear sides of the gear 9. When the side block 19 moves simultaneously with the toothed plate 10, the limit block 20 will block the movement of the side block 19. After the side block 19 is blocked from moving, the toothed plate 10 will also stop moving. Through the cooperation of the side block 19 and the limit block 20, the movement range of the toothed plate 10 is restricted, preventing the toothed plate 10 from moving excessively and thus getting disengaged from the connection with the gear 9. The size of the grinding head 15 is adapted to the size of the inner circle of the stainless steel pipe fitting body 4, so as to ensure that the outer surface of the grinding head 15 is in close contact with the inner wall of the stainless steel pipe fitting body 4, thereby ensuring that the grinding head 15 can grind the inner wall of the stainless steel pipe fitting body 4 smoothly.

[0026] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in any other form. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
