Description

Technical Field

[0001] This utility model relates to the field of hardware manufacturing technology, specifically a grinding device for hardware manufacturing. Background Technology

[0002] Hardware accessories refer to machine parts or components made of hardware, as well as some small hardware products. They can be used independently or as auxiliary tools, such as hardware tools, hardware components, daily-use hardware, building hardware, and security products. Most small hardware products are not final consumer goods, but rather supporting products, semi-finished products, and tools used in the production process of industrial manufacturing. Only a small portion of daily-use hardware products are essential consumer tools for people's lives. Decorative hardware includes hardware tubes used to manufacture stainless steel towel bars, which are polished at the ends using a polishing device.

[0003] Because the outer wall of the newly produced hardware has burrs, it is necessary to polish the outer wall of the hardware. Otherwise, the burrs on the outer wall can easily prick the hand when the hardware is used. Cylindrical hardware cannot rotate automatically during polishing and must be manually turned over, which not only wastes time but also reduces work efficiency. At the same time, when polishing round tube hardware, the burrs inside the tube are not polished well. Utility Model Content

The connecting plate 504 can be quickly disassembled to accommodate different specifications of grinding rings 505 and grinding heads 506. The grinding ring 505 is a diamond grinding wheel, and the grinding head 506 is a cylindrical design with an alumina abrasive grain covering its surface, supporting pneumatic or electric drive rotation.

[0028] The support assembly 6 includes a movable plate 601, which is slidably fitted between two mounting plates 2. A ring 602 is provided on the top surface of the movable plate 601. A first bearing 603 is installed inside the ring 602. The inner ring of the first bearing 603 is installed on the mounting column 503. A linear bearing is installed at the bottom of the movable plate 601, which is precisely fitted with the guide rail of the mounting plate 2. A locking handle is provided on the side to fix the position. An angular contact bearing 603 is embedded in the ring 602 to bear axial and radial loads. A grease nipple is added to the outer ring to extend its service life.

[0029] A sliding groove is formed between the two mounting plates 2. The support component 6 is movably set inside the sliding groove. Two clamping components 7 are slidably engaged between the two mounting plates 2. A hardware tube 8 is set between the two clamping components 7. The grinding ring 505 and the grinding head 506 are engaged at both ends of the hardware tube 8. The mounting plate 2 is an L-shaped plate. A row of threaded holes 201 are opened on the mounting plate 2. Bolts 9 are set on the clamping components 7. The bolts 9 are threaded and engaged inside the threaded holes 201.

[0030] The clamping assembly 7 includes a first arc plate 701 and a second arc plate 702. A sliding plate 703 is mounted on the bottom surface of the first arc plate 701. The sliding plate 703 slides in the grooves of the two mounting plates 2. The sliding plate 703 integrates a scale and uses the threaded hole 201 of the mounting plate to realize digital adjustment of the spacing. The bolt 9 is a wing nut for easy manual operation. The back of the first arc plate 701 is welded with reinforcing ribs. The anti-slip strip 10 is made of polyurethane and has an interlaced diamond pattern to increase friction. Radial adjustment is achieved through the threaded rod 707. A handwheel is added to the end of the threaded rod and the scale is marked. The second bearing 706 is a self-aligning bearing to compensate for installation deviations. The cylinder 709 has a self-lubricating copper sleeve embedded in it to reduce wear.

[0031] The first arc-shaped plate 701 has side plates 704 at both ends. A mounting ring 705 is installed on the top surface of the side plate 704. A second bearing 706 is installed inside the mounting ring 705. A threaded rod 707 is installed on the inner ring of the second bearing 706.

The anti-slip strips 10 are attached to the side wall of the hardware tube 8.

[0032] When using a grinding device to process and grind hardware parts such as metal tubes 8, the distance between the two clamping components 7 inside the slide groove is adjusted according to the length of the metal tube 8. The threaded rod 707 of the clamping component 7 is rotated to adjust the distance between the first arc plate 701 and the second arc plate 702, so that the metal tube 8 can be fixed between the first arc plate 701 and the second arc plate 702, limiting the grinding position of the metal tube 8. The cylinder 502 inside the mounting frame 501 on the grinding component 5 is activated. The extension and retraction end mounting column 503 of the cylinder 502 drives the connecting plate 504, the grinding ring 505, and the grinding head 506. The support component 6 moves within the grooves of the two mounting plates 2, causing the grinding ring 505 to fit onto the outer wall of one end of the hardware tube 8. The grinding head 506 is positioned inside one end of the hardware tube 8. The motor on the motor base 3 is started, causing the grinding ring 505 and the grinding head 506 to rotate simultaneously. The mounting column 503 rotates inside the ring 602, thus grinding the burrs at the end of the hardware tube 8. The two grinding components 5 work simultaneously to grind both ends of the hardware tube 8 at the same time, improving grinding efficiency. The setting of the grinding ring 505 and the grinding head 506 simultaneously grinds the inner and outer walls of the ends of the hardware tube 8, ensuring the grinding effect at the ends.
