Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe processing, and in particular to a T-shaped pipe end face grinding device. Background Technology
[0002] T-tube end face grinding equipment is a specialized device for precision machining of the end faces of T-tubes or other pipes. It mainly uses high-speed rotating grinding wheels and other grinding tools to cut the end face of the pipe after cutting, so as to eliminate defects such as burrs and oxide scale, while ensuring that the dimensional accuracy, flatness, perpendicularity and surface roughness of the end face meet the design requirements. It is commonly used in pipeline connection or welding pretreatment scenarios in chemical, petroleum, nuclear power and other fields. The equipment usually consists of a grinding execution system, a workpiece clamping system, a feed and control system and a cooling and dust removal system. The process parameters can be adjusted according to the pipe material and processing requirements to ensure the processing quality.
[0003] In the prior art, compared with the Chinese utility model with announcement number CN222002858U, a T-shaped pipe end face grinding device is disclosed. It achieves multi-face grinding after clamping the pipe with a fixture. However, in the actual processing, burrs will be generated due to the hardness of the material itself during end face grinding. The general way to deal with this is to perform a deburring process after grinding. However, multiple positioning is required, which causes the machining center of the burr to deviate from the original machining center during the second positioning. This results in inconsistent wall thickness after burr treatment. This does not affect the basic pipe field, but it may affect the accuracy of subsequent welding in precision pipes, thus affecting the processing quality. Utility Model Content

This allows for rapid grinding and burr removal in the same workstation, and the flexible grinding avoids the generation of secondary burrs, improving work efficiency and quality.

[0032] The present invention will be further described below with reference to the accompanying drawings:
[0033] like Figures 1-9As shown, a T-tube end face grinding device includes a clamp 5 for fixing and clamping a T-tube 6, a grinding mechanism 2 for grinding the end face of the T-tube 6, a switching mechanism 3 for flexibly treating the burrs at the edges and corners after grinding the end face of the grinding mechanism 2, and an adjustment mechanism 7. The grinding mechanism 2 is mounted on the main power mechanism 1, and a telescopic mechanism 4 is connected to the bottom of the main power mechanism 1. The switching mechanism 3 is movably connected to the grinding mechanism 2.
[0034] The main power mechanism 1 includes a base 41, a fixed plate 42 is installed on the upper end of the base 41, a movable plate 43 is provided on the front side of the fixed plate 42, a pressure cylinder 44 is provided on the movable plate 43, a grinding motor 11 of the main power mechanism 1 is fixedly connected to the movable plate 43 above the pressure cylinder 44, the power output end of the grinding motor 11 is connected to the main shaft 13 through a coupling 12, a grinding head 21 of the grinding mechanism 2 is installed at the end of the main shaft 13, a fixing ring is provided on the outer end face of the grinding head 21, and a grinding disc 22 is provided outside the fixing ring;
[0035] The switching mechanism 3 includes a telescopic cylinder 31, which is fixedly connected to the base 41. A top block 32 is installed at the end of the piston rod of the telescopic cylinder 31. Four sets of top rods 34 are evenly arranged on the grinding head 21. One end of the top rod 34 is connected to a pressure plate 33, and the other end of the top rod 34 is connected to a first stress ring 35 and a second stress ring 36. The first stress ring 35 is located outside the second stress ring 36. The first stress ring 35 and the second stress ring 36 are slidably connected to the grinding head 21.
[0036] In this embodiment, when the first stress ring 35 and the second stress ring 36 are in their initial positions, the fixing ring of the grinding disc 22, the first stress ring 35, and the second stress ring 36 are on the same end face, which ensures the initial grinding effect.
[0037] In this embodiment, the adjustment mechanism 7 includes a flipping frame 71, a rotating shaft 72, and a support spring 73. Several flipping frames 71 and rotating shafts 72 are provided and arranged in a circumferential array on the end face of the first stress ring 35. A limiting groove 74 is formed on the end face of the first stress ring 35 to restrict the flipping frame 71 from flipping. A support spring 73 is provided on one side of the rotating shaft 72 corresponding to the axis of the grinding head 21.
[0038] In this embodiment, the grinding disc 22 is connected to the flipping frame 71 and the second stress ring 36 by a snap-fit connection, which facilitates the replacement of the grinding disc 22.
[0039] In this embodiment, the flipping angle of the flipping frame 71 and the rotating shaft 72 is 0°-10°.
[0040] In this embodiment, the pressure plate 33 and the push rod 34 are fixedly connected, the push rod 34 is fixedly connected to the first stress ring 35 and the second stress ring 36, and the grinding head 21 has a hole formed through the push rod 34.
[0041] In this embodiment, the top block 32 is fixedly connected to the piston rod of the telescopic cylinder 31, and the top block 32 is slidably engaged with the rotating pressure plate 33.
[0042] Working principle: The grinding disc 22 is replaced as needed to grind the T-shaped tube 6. The clamp 5, which fixes the T-shaped tube 6, is transferred to the three grinding mechanisms 2 by the external conveying mechanism (not shown). The pressurizing cylinder 44 is started, which drives the grinding head 21 and the grinding disc 22 to extend and grind the end face of the T-shaped tube 6.
[0043] By controlling the pressure of the pressurizing cylinder 44, sufficient grinding force is applied to the end face of the T-tube 6 to ensure grinding of the end face. During the grinding process, burrs will be generated on the end face of the T-tube 6. After the end face is ground to the required size, the pressurizing cylinder 44 is retracted by 2mm to reduce the pressure at the end. The telescopic cylinder 31 is then activated, causing the top block 32 to press against the pressure plate 33, which in turn causes the top rod 34 to extend the first stress ring 35 and the second stress ring 36 (as shown in the image). Figures 6 to 7 As the grinding disc 22 changes, due to its inherent toughness and the reverse pressure provided by the pipe end face, the flipping frame 71 and the rotating shaft 72 are pulled inward by the grinding disc 22. The second stress ring 36 does not deform, causing the grinding disc 22 to bend in a V-shape. During the change, the support spring 73 is also a soft support. Thus, the grinding disc 22 gradually expands outward and flexibly grinds the burrs on the pipe end face during the change, thereby ensuring the quality of the port.
[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
