Abstract
The utility model relates to an improved structure for a spring mounting and demounting device of a damper, which resolves the problem of short service life in the prior art and comprises a frame base. An oil pump is disposed on an oil pump seat which is arranged on the frame base, and a pressure relief valve which is a screw top type pressure relief valve is arranged on one side of the oil pump seat corresponding to the oil pump. By means of the structure, a steel ball is tightly pushed by rotation of a thread, so that the oil pump can be sealed. Furthermore, the improved structure is quite simple and long in service life.
Description
Technical field
The utility model relates to a kind of absorber spring changer structure-improved.
Background technology
In the maintenance process of various motor vehicles,, need utilize the absorber spring changer that absorber spring is carried out dismounting usually for absorber spring is keeped in repair.
The absorber spring changer, as shown in Figure 1, it comprises a spring support by framework pillar and end fixed thereon as standing part, the free-ended mobile seat of oil pump and oil pump is provided with relief valve as movable part below oil pump; During use; Close relief valve,, make the oil pump free end drive the spring support of mobile seat on framework pillar and move then through foot-operated mode oil-feed pump pressurization; Thereby the absorber spring that is clipped in spring support and move between the seat is exerted pressure, until reaching predetermined requirement; After pressure process finishes, only need open relief valve and get final product.
Said structure is comparatively simple, and is easy to use, so the scope of application is wider.But above-mentioned relief valve is push-down, and principle is to be that a push rod (type be columniform bearing pin) with the opposite is pushed steel ball open through the lever principle of step the purpose of realization pressure release in pressure release by the check valve that the compression spring withstands steel ball.This structural disadvantages one: rod diameter is less, and is easily crooked, causes can't pushing open after the bending being stuck in after steel ball or the bending steel ball can't be resetted.Shortcoming two: after the sealing ring on the push rod is aging the pusher slide dynamic resistance is strengthened, the compression spring of back also fatigue can occur after long-term the use, and the resistance owing to push rod of the spring after the fatigue can't make oil pump failure with steel ball push-tight sealing.
The utility model content
For overcoming above-mentioned defective, the purpose of the utility model is to provide a kind of absorber spring changer structure-improved of simple in structure, long service life.
For achieving the above object; The absorber spring changer structure-improved of the utility model; Comprise gantry base, on described gantry base, be provided with the oil pump seat, described oil pump seat is provided with oil pump; Be provided with relief valve at the corresponding described oil pump of oil pump seat one side, described relief valve is the screw-top relief valve.
Wherein, Described screw-top pressure-relief valve structure is specially: the position of corresponding accumulator and piston chamber is respectively equipped with oil inlet passage and oil discharge passage on described oil pump seat; Between described oil inlet passage and oil discharge passage, be provided with valve chamber; Corresponding oil discharge passage is provided with valve plug in described valve chamber, and corresponding valve plug and oil discharge passage are provided with spiral valve rod, and it is outer and pedal stroke is affixed that the control end of described spiral valve rod stretches out the oil pump seat.
Particularly, the outer spiral valve rod of said oil pump seat is provided with back-moving spring.
Particularly, described valve plug is a steel ball.
Particularly, described oil pump seat is sharp tail band ear formula, and its underpart is connected the oil pump seat through bearing pin with frame.
Adopt said structure, utilize rotatablely moving of screw thread, thereby realize the sealing of oil pump, very simple of this structure, long service life the steel ball push-tight.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is a middle screw-top pressure-relief valve structure sketch map embodiment illustrated in fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1; The absorber spring changer structure-improved of the utility model; It comprises a spring support 11 by framework pillar 1 and end fixed thereon as standing part, and the free-ended mobile seat of oil pump 2 and oil pump 21 is provided with relief valve 3 as movable part below oil pump; During use; Close relief valve,, make the oil pump free end drive the spring support of mobile seat on framework pillar and move then through foot-operated mode oil-feed pump pressurization; Thereby the absorber spring that is clipped in spring support and move between the seat is exerted pressure, until reaching predetermined requirement; After pressure process finishes, only need open relief valve and get final product.Described relief valve is the screw-top relief valve.
Like Fig. 2 and shown in Figure 1, on described gantry base 5, be provided with oil pump seat 4, described oil pump 2 is arranged on the oil pump seat 4, is provided with relief valve 3 at the corresponding described oil pump of oil pump seat 4 one sides,
Wherein, Described screw-top pressure-relief valve structure is specially: the position of corresponding accumulator 6 and piston (chamber) 7 is respectively equipped with oil inlet passage and oil discharge passage on described oil pump seat 4; Between described oil inlet passage and oil discharge passage, be provided with valve chamber; Corresponding oil discharge passage is provided with valve plug 31 in described valve chamber, and corresponding valve plug 31 is provided with spiral valve rod 32 with oil discharge passage, and it is outer and pedal stroke 33 is affixed that the control end of described spiral valve rod stretches out the oil pump seat.Among Fig. 2, valve plug 31 is a steel ball.
As the improvement of the utility model, the outer spiral valve rod of said oil pump seat is provided with back-moving spring 34.Be contained in outside back-moving spring and utilize the thrust of the rotation of screw thread to reset, also greatly reduce requirement simultaneously torsion spring torsion to valve plug,
Described oil pump seat is sharp tail band ear formula, and its underpart is connected oil pump seat 4 through bearing pin 8 with gantry base 5; This structure makes itself and frame that certain scope of activities arranged, even column produces deviation in welding the time, also can be offset by the connection of the base of activity, thereby the efficient of production is promoted greatly, has also improved the quality of product.
