Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pipe grinding, and in particular relates to a pipe grinding device. Background Art
[0002] Pipe fittings are widely used in all walks of life. The surface quality of pipe fittings is directly related to their use effect and life. During the production process, pipe fittings may have some surface defects, such as burrs, rust, wear, etc. These problems will not only affect the appearance of the pipe fittings, but also have a certain impact on their flow performance and service life. Therefore, grinding pipe fittings is a necessary process to improve the surface quality and overall performance of pipe fittings.
[0003] Currently, when grinding pipe fittings, the pipe fittings need to be fixed with a vise first, and then the operator grinds the workpiece with a handheld grinder.
[0004] However, with this grinding method, when grinding elbows and other pipe fittings, the vise needs to hold most of the pipe fitting to maintain stability, and the grinder can only grind the part not clamped by the vise, resulting in a pipe fitting that needs to be clamped and ground repeatedly, resulting in low grinding efficiency. Utility Model Content

The operation is more convenient and avoids the problem of low efficiency caused by multiple adjustments of the clamping tool. At the same time, by arranging multiple layers of grinding pieces, after the outer grinding piece is damaged by grinding, it can be used again after the outermost grinding piece is peeled off. It is convenient and quick to use.
[0011] Furthermore, the polishing piece is a strip-shaped polishing piece, and at least two layers of the polishing pieces are circumferentially staggered and distributed with the mounting hole as the center.
[0012] Furthermore, the polishing pieces of two adjacent layers are staggered to form a cross-shaped polishing sheet with the mounting hole as the center.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0032] like Figure 1-2 As shown, the utility model provides a pipe grinding device, which includes: a base, a grinder and a grinding assembly.
[0033] The grinder is installed on the base, and the grinding assembly is installed on the output end of the grinder. The grinder drives the grinding assembly to rotate. The grinding assembly includes a plurality of stacked grinding pieces, wherein the grinding pieces are grinding sandpapers. A mounting hole matching the output end of the grinder is provided at the rotation center of the grinding piece. The mounting hole is arranged at the rotation center of the grinding piece to keep the grinding piece stable when it rotates. The grinding piece is fixed to the output end of the grinder through the central mounting hole, and the grinding surface of the grinding piece faces outward.
[0034] By installing the grinding assembly on the grinding machine, the grinding machine drives the grinding assembly to rotate quickly, and the operator holds the pipe fitting close to the outer grinding surface of the grinding assembly for grinding. The operation is more convenient and avoids the problem of low efficiency caused by multiple adjustments of the clamping tool. At the same time, by arranging multiple layers of grinding pieces, after the outer grinding piece is damaged by grinding, it can be used again after the outermost grinding piece is peeled off. It is convenient and quick to use.
[0035] In this embodiment, the grinding piece is a strip-shaped grinding piece, and at least two layers of the grinding piece are circumferentially staggered around the mounting hole, wherein the mounting hole is located at the center of the strip-shaped grinding piece, which is not shown in the figure due to the obstruction of the conical nut.
[0036] The grinding pieces are cut into strips and then staggered in the center circumferential direction, so that grinding pieces can be saved while the grinding surfaces formed by the rotating grinding pieces can achieve the same grinding effect.
[0037] The grinding pieces are preferably arranged at even intervals in the circumferential direction to ensure that the multi-layer strip-shaped grinding pieces form a rotationally stable structure, thereby achieving a better grinding effect.
[0038] Specifically, the polishing pieces of two adjacent layers are staggered around the mounting hole to form a cross-shaped polishing sheet, that is, after the mounting holes in the two polishing pieces correspond to each other, they are staggered 90 degrees around the mounting hole, and the two polishing pieces are perpendicular to each other to form a cross-shaped polishing sheet.
[0039] The cross-shaped structure formed by the two grinding pieces can maintain good balance during rotation. At the same time, the rotating grinding surface formed by the cross structure after rotation can have a better uniform grinding effect.
[0040] In one embodiment, since the grinding assembly is formed by overlapping multiple layers of cross-shaped grinding sheets, the multiple cross-shaped grinding sheets are arranged at equal intervals in the circumferential direction with the mounting hole as the center.
[0041] In another embodiment, a plurality of the cross-shaped grinding sheets are overlapped circumferentially with the mounting hole as the center, that is, each layer of cross-shaped grinding sheets is aligned circumferentially to form a cross-shaped structure as a whole, which is convenient for fixing multiple layers.
[0042] When fixing the multi-layer grinding pieces, the multiple grinding pieces are aligned and fixed by being installed in the center and are circumferentially rotationally staggered. Specifically, in the overlapping area formed by the circumferential staggered grinding pieces, at least one set of fasteners are rotationally symmetrically arranged with the mounting holes to fix the multiple grinding pieces.
[0043] In this embodiment, two groups of fasteners are fixed, and the two groups are arranged in rotational symmetry with the mounting holes. One group of fasteners includes two symmetrically formed fastening nails that penetrate the multiple layers of polishing parts along the inner edge of the overlapping area for fixing.
[0044] In order to improve the grinding efficiency, the grinding piece can be set as a double-headed grinder, and the grinding components are respectively installed on the two output ends of the grinder. The grinding efficiency is improved by grinding at both ends simultaneously.
[0045] Specifically, the output end of the grinder has a tapered thread and a tapered nut matching the tapered thread, so that the grinding component is clamped and fixed to the output end of the grinder. By setting the output end of the grinding piece to be tapered, the tapered end facilitates the mounting hole in the grinding component to be sleeved on the output end, and the grinding component can be clamped and fixed by the tapered thread and the tapered nut.
[0046] Since the grinding assembly rotates at high speed, the grinding assembly is installed on the output end of the grinder. To ensure safety, an extension rod is connected to the output end of the grinder, and the output end of the grinding piece is extended by the extension rod. The grinding assembly is installed at the end of the extension rod away from the grinder. During grinding, the operator can stay away from the grinder, which is safer and more reliable.
[0047] In addition, when a double-head grinder is used, the two grinding components on the double-head grinder can also be farther away from each other so as not to affect each other and improve safety.
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
