Embodiment 1

[0029] A short pipe inner wall grinding device according to an embodiment of the present invention, such as figure 1 , figure 2 and image 3 As shown, it includes: a grinding drive device 1, several rotating grinding parts 2 and a rotary feeding part, the grinding drive device 1 includes a driving motor 5, a driving bevel gear 6 and a bracket device, and the driving motor 5 and the driving bevel gear 6 are arranged on the bracket device Above, the driving motor 5 is used to drive the driving bevel gear 6 to rotate; in the present invention, in the specific application process, there are 3 rotating grinding parts 2, and the 3 rotating grinding parts 2 are evenly distributed on the central axis of the driving bevel gear 6. on the circumference of the axis;

[0030] Such as image 3 As shown, the first bevel gear 7, the second bevel gear 8, the third bevel gear 9 and the grinding runner 10 are arranged on the rotating grinding part 2, the first bevel gear 7 meshes with the dr...

Embodiment 2

[0039] Compared with Embodiment 1, Embodiment 2 is different in that the connection between the first bevel gear 7 and the second bevel gear 8 is a sleeve fitting connection, and a spring is provided in the sleeve, and the spring is used to connect the first bevel gear to the second bevel gear. The second bevel gear 8 is ejected outwards, and the adjustment of the spacing distance between the first bevel gear 7 and the second bevel gear 8 is realized by changing the compression amount of the spring, and the elastic force generated by the spring compression can provide the second bevel gear 8 1. The third bevel gear 9 and the grinding wheel 10 generate radial elastic force as a whole, and there is a certain extrusion between the grinding wheel 10 and the inner wall of the pipe to be polished, which is more conducive to improving the grinding effect and grinding accuracy. At the same time, the structure can The grinding device has self-adaptive ability, without manual adjustment,...

Embodiment 3

[0041] Compared with embodiment 1, the difference of embodiment 3 is that the number of rotating grinding parts 2 is set to four, that is, the four rotating grinding parts 2 are evenly distributed on the circumference with the central axis of the driving bevel gear 6 as the axis, The four rotating grinding parts 2 simultaneously grind the inner wall of the pipe fitting to be polished. At this time, a transmission motor with a higher rotational speed can be used to increase the speed of the grinding device during the grinding process without affecting the grinding effect, and the efficiency is higher.

[0042] In the specific use process of the present invention, after the pipe to be polished is fixed on the workbench, the grinding device is set in cooperation with the pipe to be polished, and the motor control device is used to control the speed of the driving motor 5 to control the grinding accuracy. Control the drive motor, thereby controlling the speed of the axial feed move...

Abstract

The invention discloses an inner wall grinding device for a short tube and relates to the technical field of grinding tools. The inner wall grinding device comprises a grinding driving device, a plurality of rotary grinding parts and a rotary feeding part, wherein the grinding driving device comprises a driving motor, an active bevel gear and a bracket device; the plurality of rotary grinding parts are uniformly distributed on the circumference taking the central shaft of the active bevel gear as the axis; the rotary feeding part comprises a rotary bushing and a transmission device, the grinding device can rotate in the rotary bushing, and the transmission device is used for driving the rotary bushing to carry out an axial feeding movement. The grinding driving device drives the pluralityof rotary grinding parts simultaneously, and meanwhile, the grinding precision of the inner wall of a pipefitting can be improved by increasing the quantity of the rotary grinding parts. Moreover, a cleaning part is of a dust collecting structure, so that probable pollution can be prevented effectively, and a neat and clean working environment is guaranteed. The grinding device can grind pipefittings of different inner diameters by adopting a pitch adjusting device, and the advancing direction of the grinding device is controlled, so that high precision grinding is achieved.

Description

technical field [0001] The invention relates to the technical field of grinding tools, in particular to a short tube inner wall grinding device. Background technique [0002] At present, most manufacturers mainly use manual grinding for the internal and external grinding of the pipe mouth, that is, the workers use electric or pneumatic grinding machines to grind the outer wall of the pipe first and then the inner wall, so that the traditional and backward processing methods have fallen behind, and the efficiency of manual grinding Low labor intensity, high labor intensity and harsh working environment; for example, in shipbuilding and chemical industries, a large number of pipelines need to be laid. When two pipelines need to be connected, flanges need to be welded on both ends of the pipes, and then the two flanges Connect with bolts. When the pipe needs to be welded with the flange, the inside and outside of the end of the pipe need to be ground to ensure the welding qual...
