Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically to a polishing equipment for processing hardware parts. Background Technology

[0002] Grinding is a crucial step in the processing of hardware parts, aiming to remove burrs and rust from their surfaces to achieve the required smoothness and precision. Copper pipes, with their excellent corrosion resistance and thermal conductivity, are commonly used in HVAC and chemical industries. During the welding of copper pipes, it is typically necessary to remove burrs from the end faces and the oxide layer from the circumferential surface. Since grinding involves both the end faces and the circumference, regardless of whether a belt grinder or a disc grinder is used, after grinding one side, the copper pipe needs to be rotated 90° before grinding the other side. If the copper pipe is long, this process significantly impacts processing efficiency. Utility Model Content

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0013] Please see Figure 1-2 This utility model provides a technical solution: a grinding device for processing hardware parts, including a base 1, a motor a4 and a grinding belt 10. A mounting frame 2 is welded to the upper side of the base 1. A vertical mounting plate 3 is fixedly installed on the front side of the mounting frame 2. The motor a4 is fixedly installed on the back of the mounting plate 3. The output shaft of the motor a4 passes through the mounting plate 3 and is fixedly installed with a drive wheel 5. A support plate 8 that can tilt and swing is hinged to the end of the mounting frame 2 away from the motor a4. The support plate 8 has a V-shaped symmetrical structure. Symmetrical support wheels 9 are installed at the upper and lower ends of the support plate 8. An arc-shaped limiting hole 11 with the hinge point as the center is opened on the support plate 8. A hand-tightening bolt that is screwed to the mounting frame 2 is inserted into the arc-shaped limiting hole 11. After the hand-tightening bolt is tightened, the support plate 8 is fixed.

A tensioning wheel 7 is mounted on the front side of the tensioning swing arm 6. The grinding belt 10 is connected between the drive wheel 5, the support wheel 9, and the tensioning wheel 7. (See the attached instruction manual.) Figure 1For example, the tensioning arm 6 has a clockwise rotation tension force, the tensioning wheel 7 tensions the grinding belt 10, and the grinding belt 10 between the two support wheels 9 is the grinding section. Two parallel vertical plates 12 are welded to the upper surface of the base 1, and two parallel grinding wheels 13 are installed between the two vertical plates 12.
