AI Technical Summary
In the existing technology, the disassembly and inspection efficiency of the spline shaft connecting bars in horizontally arranged rolling mills is low and there are safety hazards, especially the difficulty of disassembly and installation caused by tooth surface wear.
Design a disassembly and inspection fixture including a support and a connecting rod. The support is adapted to a flat-head toothed hole. The position of the support is adjusted by the connecting rod to provide stable support and is equipped with a limit sleeve and an anti-slip sleeve. The length of the connecting rod is adjustable to maintain a safe distance.
It improved the efficiency of disassembly and inspection operations, reduced operational risks, and ensured operational safety and structural stability.

A dismounting tool for spline shafts of connecting rods of a horizontal arrangement rolling mill for bars, characterized in that, It includes a support part (1) and a connecting rod (2) connected to the support part (1). The support part (1) is adapted to the shape of the flat tooth hole. When in use, the support part (1) is inserted into the flat tooth hole, and pressure is applied to the connecting rod (2) to adjust the position of the support part (1) so that the flat tooth is kept in a balanced state.
2. A kind of dismounting tool for the spline shaft of connecting rod of horizontal arrangement rolling mill of bar according to claim 1, with the characteristics that, The distance between the edge of the support part (1) and the inner hole of the tooth is 3-5mm.
3. A kind of dismounting tool for the spline shaft of connecting rod of horizontal arrangement rolling mill of bar according to claim 1, with the characteristics that, The support part (1) includes two support plates, and the axial length of the support part (1) formed by the combination of the support plates is the same as the depth of the inner hole of the flat-head tooth.
4. A kind of dismounting tool for the spline shaft of connecting rod of horizontal arrangement rolling mill of bar according to claim 1, with the characteristics that, The connecting rod (2) has a thread at its tail, and the extension rod is connected to the connecting rod (2) through the thread.
5. A kind of dismounting tool for the spline shaft of connecting rod of horizontal arrangement rolling mill of bar according to claim 3, with the characteristics that, The support plate is made of steel.
6. A kind of dismounting tool for the spline shaft of connecting rod of horizontal arrangement rolling mill of bar according to claim 3, with the characteristics that, The support plate has a through hole in the middle, which is compatible with the diameter of the connecting rod (2). The support plate is inserted into the connecting rod (2) through the through hole and fixed at the designated position of the connecting rod (2) by tightening the nut.
7. A kind of dismounting tool for the spline shaft of connecting rod of horizontal arrangement rolling mill of bar according to claim 1, with the characteristics that, The lower outer edge of the connecting rod (2) is fitted with an anti-slip sleeve.
8. A dismounting tool for spline shafts of connecting rods of a horizontal arrangement rolling mill for bars according to claim 3, characterized in that, A limiting sleeve is provided between the two support plates, and the limiting sleeve is located on the outer edge of the connecting rod (2).
