Technical Field
[0001] This utility model relates to the field of water pipe joint grinding technology, and in particular to a high-strength water pipe joint grinding equipment. Background Technology
[0002] After machining, burrs easily remain on the inner and outer walls of plumbing pipe fittings (especially those made of high-strength materials). Traditional manual grinding is inefficient, inaccurate, and produces severe environmental pollution from flying metal shavings. Existing equipment generally suffers from three major drawbacks: limited clamping and rotation: most clamps cannot simultaneously achieve the combined motion of workpiece lifting, rotation, and double-end grinding, resulting in repeated adjustments after each clamping; weak dust protection: open-type grinding causes high-temperature metal shavings to fly, which is not only difficult to clean but also easily damages the precision components of the equipment; and complex tool changing process: different specifications of fittings require specific grinding heads, and the traditional bolt fastening method is time-consuming to disassemble and assemble, affecting the continuity of the production line. To address these issues, we propose a high-strength plumbing pipe fitting grinding equipment. Utility Model Content

[0011] This utility model provides a high-strength plumbing pipe joint grinding device. It has the following beneficial effects: (1) The high-strength plumbing pipe joint grinding equipment achieves complex spatial trajectory control through a three-stage coordinated operation of a three-jaw chuck, an electric slide table, and a rotary motor: the electric slide table and slider drive the three-jaw chuck for vertical positioning, ensuring precise alignment of the workpiece with the grinding head; the rotary motor drives the connecting column via a rotating column, forcing the mounting column and grinding head to rotate at high speed to generate the main cutting force. The rotating grinding head of the connecting column cuts burrs, and after grinding, the three-jaw chuck is rotated, enabling the removal of burrs from the inner and outer walls and end faces of both ends of the joint in a single clamping operation, while avoiding the secondary clamping errors of manual clamping.
[0012] (2) The high-strength water pipe joint grinding equipment has a telescopic dust cover: the retaining ring is embedded in the retaining groove to form a basic seal, and the threaded ring is screwed out in the threaded cavity to extend the cover wall, which can be adapted to joints of different lengths and completely cover the grinding area; negative pressure dust removal linkage: the suction pipe guides the splashing iron filings into the suction machine to avoid high temperature debris from damaging the guide rail of the electric slide table or intruding into the transmission mechanism of the three-jaw chuck; synergistic value: the dust removal system starts the suction machine simultaneously during grinding, and the iron filings are immediately removed, which is convenient for cleaning operations. When the grinding head needs to be replaced, only the nut needs to be loosened and the guide block slides out along the preset groove, and a new module can be replaced within seconds.

In use, the high-strength plumbing pipe joint to be ground is passed through the three-jaw chuck 4. The high-strength plumbing pipe joint is fixed in place. The electric slider 3 drives the three-jaw chuck 4 and the high-strength plumbing pipe joint to move, causing the connecting column 10 to rotate. The connecting column 10 drives the grinding head 11 to rotate, and the grinding head 11 grinds the high-strength plumbing pipe joint to remove burrs. During the grinding process, the retaining ring 19 and the threaded ring 21 are used to shield the iron filings after grinding to prevent iron filings from flying and facilitate cleaning. The side of the electric slider 3 is fixedly installed with a servo motor 5, and the side of the three-jaw chuck 4 is fixedly connected to the output end of the servo motor 5. After the high-strength plumbing pipe joint is clamped by the three-jaw chuck 4, the servo motor 5 is started. The servo motor 5 drives the three-jaw chuck 4 to rotate, and the three-jaw chuck 4 drives the high-strength plumbing pipe joint, thereby grinding and deburring both ends of the high-strength plumbing pipe joint. The grinding structure includes a mounting column 12 movably installed inside the mounting cavity 23. A grinding head 11 is fixedly mounted on the upper end of the mounting column 12. The connecting column 10 drives the mounting column 12 to rotate, which in turn drives the grinding head 11 to rotate. The rotating grinding head 11 grinds and removes burrs from the high-strength plumbing pipe joint. The upper end of the connecting column 10 has two first guide grooves 13. A second guide groove 14 is provided on one side where the two first guide grooves 13 intersect. A third guide groove is provided on the upper side of the second guide groove 14.

[0018] The working principle of this utility model: In use, the high-strength plumbing pipe joint to be ground is fixed by the three-jaw chuck 4. The electric slider 3 moves the three-jaw chuck 4 and the high-strength plumbing pipe joint, causing the connecting column 10 to rotate. The connecting column 10 then rotates the grinding head 11, which grinds the high-strength plumbing pipe joint to remove burrs. During grinding, the retaining ring 19 and threaded ring 21 shield the metal shavings after grinding, preventing them from flying and facilitating cleaning. After the high-strength plumbing pipe joint is clamped by the three-jaw chuck 4, the servo motor 5 is started. The servo motor 5 drives the three-jaw chuck 4 to rotate, which in turn moves the high-strength plumbing pipe joint, thus grinding the high-strength plumbing pipe joint. Both ends are ground to remove burrs. The connecting column 10 drives the mounting column 12 to rotate, and the mounting column 12 drives the grinding head 11 to rotate. The high-strength water pipe joint is ground and deburred by the rotating grinding head 11. After the guide block 16 is moved into the third guide groove 15, the nut 17 is rotated. The guide block 16 is locked by rotating the nut 17 upward, which facilitates the replacement of the size of the grinding head 11. The rotary motor 8 is started, and the rotary motor 8 drives the rotating column 9 to rotate. The rotating column 9 drives the connecting column 10 to rotate. The threaded ring 21 rotates inside the threaded cavity 20 to achieve extension and retraction. The air suction machine is started.
