Abstract
The utility model discloses a special press-mounting tool for a diesel engine crankshaft oil seal, which comprises a tool body, wherein the tool body is provided with a detachable connecting device fixedly connected with the end part of a crankshaft, one end of the tool body, close to the crankshaft, is provided with a sheathing part of the crankshaft oil seal, and an oil seal pushing device is arranged on the tool body; and a pushing block slides on the tool body and exerts force on the oil seal evenly, thus avoiding the damage to oil seals at the front part and the rear part of the crankshaft in the press-mounting process and improving the press-mounting quality and the press-mounting success rate.
Description
Technical field
The utility model relates to a kind of use for diesel engine crankshaft oil seal press mounting tool.
Background technology
The bent axle front and rear oil seals plays in the bent axle high speed rotating and to intercept that lubricating oil leaks outside in the crankcase, prevents the effect that the outer dust of crankcase enters simultaneously.Existing crankshaft oil seal press mounting tool is to adopt the mode that is threaded at gland center to realize being pressed into, this mounting means causes the oil sealing discontinuity easily, cause to press-fit in the process, influenced and press-fit quality, reduced and press-fit success rate the damage of bent axle front and rear oil seals.
The utility model content
Technical problem to be solved in the utility model provides a kind of special-purpose press mounting tool of Oil Seals in Crankshafts that press-fits the quality height, can effectively avoid press-fiting oil sealing unbalance stress in the process.
For solving the problems of the technologies described above, the technical solution of the utility model is: the special-purpose press mounting tool of Oil Seals in Crankshafts, comprise tool body, described tool body is provided with the detachable connecting device of fixedlying connected with crankshaft end, one end of the close described bent axle of described tool body is provided with the oil sealing suit portion of crankshaft oil seal, and described tool body is provided with the oil sealing thrust unit.
As optimized technical scheme, described tool body is the cylindrical tool body.
As optimized technical scheme, described detachable connecting device comprises and the corresponding installing hole of described crankshaft end-face screw, in the described installing hole connecting bolt is installed.
As optimized technical scheme, described oil sealing thrust unit comprises the external screw thread that is arranged on described cylindrical tool body outer surface, on the described cylindrical tool body outer surface promotion nut that cooperates with described external screw thread is installed, be set with oil sealing on the described cylindrical tool body between described promotion nut and the oil sealing and promote cover, the part of described cylindrical tool body is double makees described oil sealing suit portion.
As optimized technical scheme, described promotion nut periphery is installed with rotating handles.
Owing to adopted technique scheme, the special-purpose press mounting tool of Oil Seals in Crankshafts, comprise tool body, described tool body is provided with the detachable connecting device of fixedlying connected with crankshaft end, one end of the close described bent axle of described tool body is provided with the oil sealing suit portion of crankshaft oil seal, and described tool body is provided with the oil sealing thrust unit; Pushing block slides on tool body, evenly forces in oil sealing, has avoided press-fiting in the process the damage of bent axle front and rear oil seals, has improved to press-fit quality and press-fit success rate.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the partial enlarged drawing at I place among Fig. 1;
Fig. 3 is the structural representation of tool body among the utility model embodiment.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the special-purpose press mounting tool of Oil Seals in Crankshafts, comprise tool body 1, described tool body is the cylindrical tool body, described tool body 1 is provided with the detachable connecting device of fixedlying connected with bent axle 7 ends, described detachable connecting device comprises and the corresponding installing hole 14 of described bent axle 7 end face screws that 14 are equipped with connecting bolt 15 in the described installing hole; Described tool body 1 is provided with the oil sealing suit portion of crankshaft oil seal near an end of described bent axle 7, the part of described cylindrical tool body is double makees described oil sealing suit portion, described tool body 1 is provided with the oil sealing thrust unit, described oil sealing thrust unit comprises the external screw thread 10 that is arranged on described cylindrical tool body 1 outer surface, on described cylindrical tool body 1 outer surface promotion nut 2 that cooperates with described external screw thread 10 is installed, be set with oil sealing on the described cylindrical tool body 1 between described promotion nut 2 and the oil sealing 13 and promote cover 4, described promotion nut 2 peripheries are installed with rotating handles 3.
Place oil sealing to promote cover 4 the place aheads on oil sealing 13 during use, use set bolt handle 12 to be fixed on the end thread hole of bent axle 7 tool body 1, and make tool body 1 contact with gear 6, rotate rotating handles 3, drive and promote nut 2 rotations, promotion nut 2 forces in oil sealing and promotes cover 4, making oil sealing promote cover 4 moves axially along bent axle 7, evenly force in oil sealing 13, avoided press-fiting in the process, improved and press-fit quality and press-fit success rate the damage of bent axle front and rear oil seals.
Above-described only is preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, distortion of making and improvement also should be considered as protection domain of the present utility model.
