Description

Technical Field

[0001] This utility model relates to the field of grinding technology, specifically to a device for grinding weld seams at pipe ends. Background Technology

[0002] During maintenance, pipe welding is frequently involved. This process requires welding the ends of two pipes together to merge them into one. The standard for pipe end welds is: the pipe is straight, the weld is neat without protruding burrs or bumps, and there are no gaps in the weld. Pipe welding is typically done manually. After manual welding, to meet the welding standards, the weld at the pipe end needs to be ground. Current grinding methods require the worker to hold a grinding wheel in one hand and hold and rotate the pipe with the other, which is cumbersome and produces uneven grinding results. To address this, this invention provides a pipe end weld grinding device. Summary of the Invention

[0003] The purpose of this invention is to provide a device for grinding the weld seam at the pipe end, which makes the grinding operation more convenient and simple, and makes the grinding effect more uniform.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A device for grinding weld seams at pipe ends, comprising: There are two base brackets, which are set on both sides of the base plate, with a gap between the two base brackets; A vertical guide rail is vertically installed on one side of the base plate. A sliding seat is slidably installed on the vertical guide rail. A top plate is installed on the top of the vertical guide rail, and an adjustment mechanism for adjusting the lifting and lowering of the sliding seat is installed on the top plate. A grinding device, which is detachably connected to a sliding seat, is located directly above the two base brackets; A fixing mechanism is installed on one side of the sliding seat to fix the grinding device.

[0005] Furthermore, the base bracket is an angle steel structure welded onto the base plate, and the distance between the two base brackets is 3-4cm.

[0006] Furthermore, the sliding seat includes a main slider, a secondary sliding sleeve, and a mounting plate. The main slider is slidably mounted on a vertical guide rail. Two guide rods are also provided between the top plate and the bottom plate. The secondary sliding sleeve is located on both sides of the main slider and is slidably mounted on the guide rods.

[0007] Furthermore, the adjustment mechanism includes a central screw and a screw sleeve. The screw sleeve is fixedly mounted on the top plate and the central screw is threadedly connected in the screw sleeve. The bottom end of the central screw is rotatably connected to the sliding seat.

[0008] Furthermore, a side support plate is provided between the top plate and the bottom plate, and threaded sleeves are provided on both sides of the top plate. A side screw is threadedly connected to the threaded sleeves on both sides. An upper pressure frame is rotatably provided at the bottom end of the side screw. The upper pressure frame is an angle steel structure and is located directly above the bottom support.

[0009] Furthermore, the grinding device includes a housing, a grinding wheel, and a drive motor. The grinding wheel is rotatably mounted on the housing, and a drive motor for driving the grinding wheel to rotate is also provided on the housing. The housing has a first through hole and a handle is provided on one side of the housing.

[0010] Furthermore, the fixing mechanism includes a fixing rod, a spring, a pull plate, and a plug rod. The fixing rod is fixedly installed on one side of the mounting plate and has a second through hole on the mounting plate. The pull plate passes through the fixing rod and has plug rods on both sides of the pull plate. The plug rods pass through the second through hole and the first through hole. A spring connects the pull plate and the end of the fixing rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model features two base supports on the base plate to hold the pipe. Since the base supports are made of angle steel, they can be centered and limited to prevent pipes of different diameters from moving left or right. A vertical guide rail is provided on one side of the base plate, and a sliding seat is provided on the vertical guide rail. A grinding device is detachably connected to the sliding seat, and the sliding seat can be raised and lowered by an adjustment mechanism, so that the grinding device can contact the weld seam of pipe openings of different diameters. During grinding, the pipe only needs to be rotated slowly. Compared with the prior art of holding the pipe with one hand and the grinding machine with the other, this method is more convenient and simple to operate. In addition, the position of the grinding device is fixed during the process, which makes the grinding effect of the pipe opening more uniform. In this utility model, the grinding device is fixed by a fixing mechanism, which facilitates the disassembly and assembly of the grinding device. When other parts need to be ground, it can be easily disassembled and used. This utility model also includes two sets of side screws and an upper pressure frame. The upper pressure frame is raised and lowered by adjusting the side screws, so that the pipe is clamped between the upper pressure frame and the bottom support frame. This makes it easier to center and clamp the pipe, thus facilitating the welding process. Attached Figure Description
