Detailed Description
Referring to fig. 1 to 8, a deep groove ball bearing dust cover press-fitting device comprises a press-fitting block 1 and a positioning block 2, wherein a gap of 10mm-50mm is formed between the bottom end of the press-fitting block 1 and the upper end of the positioning block 2, the press-fitting block 1 is arranged in a mounting port of a riveting machine tool through a bolt 13, a cavity is formed in the press-fitting block 1, the positioning block 2 is in sliding fit with the cavity and is positioned in the cavity, a first mounting groove 3, a thread groove 6, a second mounting groove 4 and a sliding groove 7 are respectively formed in the press-fitting block 1 and the positioning block 2, when the positioning block 2 is mounted, a first spring 5 is firstly placed in the second mounting groove 4, then the upper end of the first spring 5 is placed in the first mounting groove 3, finally, the positions of the press-fitting block 1 and the positioning block 2 are fixed through screwing a fastening bolt 8 into the thread groove 6, and the first spring 5, the first mounting groove 3 and the second mounting groove 4 are respectively provided with three uniform and mutually corresponding cavities, and the end parts of the fastening bolt 8 are in sliding fit with the sliding groove 7, so that the first spring 2 can be radially arranged in the cavity of the press-fitting block 1;
Three sliding grooves 9 which are respectively arranged at intervals with the three sliding grooves 7 are formed in the positioning block 2, a sliding rod 10 is arranged in the sliding groove 9, a slidable fixed block 11 is arranged on the sliding rod 10, and second springs 12 connected with the sliding groove 9 and the fixed block 11 are sleeved on the sliding rod 10 so that the fixed block 11 automatically resets after sliding on the sliding rod 10, and the fixed block 11 is arc-shaped and convenient to match with the inner diameter of a bearing.
The utility model has the installation process and working principle: firstly, a press-fitting block 1 is manually installed at an installation port of a riveting machine tool, bolts 13 are screwed during installation to prevent sliding, a first spring 5 is placed in a second installation groove 4, the upper end of the first spring 5 is placed in the first installation groove 3, and finally, the positions of the press-fitting block 1 and a positioning block 2 are fixed by screwing a fastening bolt 8 into a thread groove 6, so that the press-fitting block 1 and the positioning block 2 are coaxial during connection, the uniform fastening displacement of uniformly distributed fastening bolts 8 is ensured, the uniform deformation of the uniformly distributed first spring 5 is ensured, and the elastic force of the first spring 5 is uniform;
