Abstract
The utility model discloses a hydraulic extractor for a steering main pin of a vehicle, and relates to the technical field of special equipment of vehicle maintenance. According to the hydraulic extractor, the upper end of a progressive lead screw (2) is sleeved on the middle part of a lever (1); a hydraulic plunger (3) is screwed on the progressive lead screw (2); a high-pressure oil seal (5) is arranged at the lower end of the hydraulic plunger (3); a hydraulic shell (4) is sleeved outside the hydraulic plunger (3) and the high-pressure oil seal (5); a hydraulic connecting valve (6) is arranged on one side of the hydraulic shell (4); an upper lock plate (8) is arranged at the lower end of the hydraulic shell (4); a lower lock plate (9) is arranged at the lower end of the upper lock plate (8); the upper lock plate (8) and the lower lock plate (9) are connected with nuts through locking screws (7); and the lower end of the progressive lead screw (2) penetrates out of the middle parts of the upper lock plate (8) and the lower lock plate (9) in sequence. The hydraulic extractor for the steering main pin of the vehicle is simple and practical, and time-saving, labor-saving, safe and efficient in operation, does not damage other unrelated accessories, and does not influence the maintenance reuse of the steering main pin.
Description
Technical field:
The utility model relates to vapour and protects the special equipment technical field, is specifically related to a kind of motor turning stub hydraulic pressure extractor.
Background technology:
At present the Automobile Service staff is taked is hammering or cooperates difficult taking-up with jack, and mode of operation is contrary to the principles of science, also waste time and energy and operate dangerous, other irrelevant auto parts machinery of easy damaged.
The utility model content:
The purpose of the utility model provides motor turning stub hydraulic pressure extractor; It is simple and practical, has solved the motor turning stub and has taken out difficult old topic, operates time saving and energy saving safe and efficient; Do not damage other irrelevant accessory, and the maintenance of pivot stud utilized again do not impact.
In order to solve the existing problem of background technology; The utility model is to adopt following technical scheme: it comprises tommy bar 1, the leading screw 2 that goes forward one by one, oil pressure plunger 3, hydraulic pressure shell 4, High-pressure oil sealing 5, oil pressure connect valve 6, locking screw mandrel 7, upper lock plate 8 and lower locking plate 9; The go forward one by one upper end of leading screw 2 is socketed in the middle part of tommy bar 1, is connected with oil pressure plunger 3 on the leading screw 2 that goes forward one by one, and oil pressure plunger 3 lower ends are provided with High-pressure oil sealing 5; And the outer cover of oil pressure plunger 3 and High-pressure oil sealing 5 is connected to hydraulic pressure shell 4; One side of hydraulic pressure shell 4 is provided with oil pressure and connects valve 6, and the lower end of hydraulic pressure shell 4 is provided with upper lock plate 8, and upper lock plate 8 lower ends are provided with lower locking plate 9; And upper lock plate 8 connects through locking screw mandrel 7 and nut with lower locking plate 9, and the lower end of the leading screw 2 that goes forward one by one passes the middle part of upper lock plate 8 and lower locking plate 9 successively.
What the utility model was taked is hydraulic principle; Upper lock plate 8 and lower locking plate 9 are fixed in the upper and lower side of stub, again with the ram spinner in upper lock plate 8, the principle of utilizing screw mandrel 2 rotations of going forward one by one to rise; Oil pressure plunger 3 is pushed into the oil hydraulic cylinder top; Connect valve 6 from oil pressure then hydraulic oil is injected, pivot stud is extruded through screw mandrel 2 lower ends of going forward one by one with enough pressure, stub is long can to rise to the hydraulic cylinder top with hydraulic plunger 3 once more through the rotation screw mandrel 2 that goes forward one by one; Press down so repeatedly, till pivot stud is extruded.
The utility model is simple and practical, has solved the motor turning stub and has taken out difficult old topic, operates time saving and energy saving safe and efficiently, does not damage other irrelevant accessory, and the maintenance of pivot stud utilized does not again impact.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
With reference to Fig. 1; This specific embodiment adopts following technical scheme: it comprises tommy bar 1, the leading screw 2 that goes forward one by one, oil pressure plunger 3, hydraulic pressure shell 4, High-pressure oil sealing 5, oil pressure connect valve 6, locking screw mandrel 7, upper lock plate 8 and lower locking plate 9; The go forward one by one upper end of leading screw 2 is socketed in the middle part of tommy bar 1, is connected with oil pressure plunger 3 on the leading screw 2 that goes forward one by one, and oil pressure plunger 3 lower ends are provided with High-pressure oil sealing 5; And the outer cover of oil pressure plunger 3 and High-pressure oil sealing 5 is connected to hydraulic pressure shell 4; One side of hydraulic pressure shell 4 is provided with oil pressure and connects valve 6, and the lower end of hydraulic pressure shell 4 is provided with upper lock plate 8, and upper lock plate 8 lower ends are provided with lower locking plate 9; And upper lock plate 8 connects through locking screw mandrel 7 and nut with lower locking plate 9, and the lower end of the leading screw 2 that goes forward one by one passes the middle part of upper lock plate 8 and lower locking plate 9 successively.
What this specific embodiment was taked is hydraulic principle; Upper lock plate 8 and lower locking plate 9 are fixed in the upper and lower side of stub, again with the ram spinner in upper lock plate 8, the principle of utilizing screw mandrel 2 rotations of going forward one by one to rise; Oil pressure plunger 3 is pushed into the oil hydraulic cylinder top; Connect valve 6 from oil pressure then hydraulic oil is injected, pivot stud is extruded through screw mandrel 2 lower ends of going forward one by one with enough pressure, stub is long can to rise to the hydraulic cylinder top with hydraulic plunger 3 once more through the rotation screw mandrel 2 that goes forward one by one; Press down so repeatedly, till pivot stud is extruded.
This specific embodiment is simple and practical, has solved the motor turning stub and has taken out difficult old topic, operates time saving and energy saving safe and efficiently, does not damage other irrelevant accessory, and the maintenance of pivot stud utilized does not again impact.
