More specifically, fig. 14 is a schematic structural diagram of an installation plate provided in an embodiment of the present invention, referring to fig. 1, 2 and 14, the linkage assembly 400 further includes an installation plate 490, the lateral support seat 420 is vertically installed at one end of the sliding plate 410, the installation plate 490 is vertically installed at the other end of the sliding plate 410, the fixed end of the telescopic mechanism 430 is connected to the installation plate 490, the telescopic end of the telescopic mechanism 430 faces the direction of the lateral support seat 420, and can be telescopic, so as to drive the cylindrical hole plugging mechanism 440 to move, and when the telescopic end stretches out, the cylindrical hole plugging mechanism 440 is driven to move towards the direction of the support seat 420, so that the conical surface sealing cushion block 441 is plugged in the first cylindrical oil hole 10-1; when the telescopic end is retracted, the cylindrical surface hole plugging mechanism 440 is driven to move in the opposite direction to the direction in which the supporting seat 420 is located, so that the conical surface sealing cushion block 441 is separated from the first cylindrical surface oil hole 10-1.
More specifically, the telescopic mechanism 430 may be a cylinder of the prior art, which has a cylinder diameter of 40mm and a piston diameter of 18mm.
Fig. 15 is a schematic structural diagram of a lateral support seat provided in an embodiment of the present invention, and referring to fig. 15, an end surface of an abutting end of the lateral support seat 420 is arc-shaped, which matches with an external shape feature of the injector body 10, so as to ensure a clamping and positioning effect of the lateral support seat 420 on the injector body 10.
The working process of the positioning device provided by the embodiment is as follows:
when the oil sprayer is applied, firstly, the limit seat 110, the first sealing seat 120 and the machine tool connecting seat 130 together with the oil sprayer body 10 are jacked up by a machine tool cylinder of the machine tool, and are pressed below the second sealing seat 320. Meanwhile, the elastic conical surface seal spacer 441 is pressed into the first cylindrical oil hole 10-1 at the side of the injector body 10 by the telescopic mechanism 430. Meanwhile, the jacking force of the telescopic mechanism 430 is transmitted to the lateral supporting seat 420 through the mounting plate 490 and the sliding flat plate 410 by the interaction principle of the forces, and the automatic centering and the automatic clamping of the positioning device are realized by the interaction, so that a high-pressure sealing environment is formed.
Then, the liquid oil after cleaning, grinding or testing can enter the seal cushion oil hole 441-1 formed in the conical surface seal cushion 441 through the oil inlet 442-1 of the oil inlet seat 442, enter the first oil duct 10-2 for cleaning and grinding, and finally flow into the external connecting pipe through the seal seat oil hole 320-1 and the transition oil duct 310-1 formed in the second seal seat 320.
The telescopic end of the telescopic mechanism 430 moves away from the lateral supporting seat 420, the convex shoulder structure 442-2 abuts against the linkage block 481 to drive the stroke adjusting seat 480 to retreat, and the stroke adjusting seat 480, together with the fixing plate 210 and the angle adjusting seat 250, retreats synchronously relative to the sliding flat plate 410, so that the release of the oil sprayer body 10 is realized.
Finally, the machine tool is retracted from the machine tool cylinder, the upper end surface of the oil sprayer body 10 is separated from the second sealing seat 320, and the oil sprayer body 10 is taken out of the mounting groove 111, so that the working procedures such as flushing and the like are completed.
The parameters in this embodiment are designed as follows:
there are sufficient positions on the fixing plate 210 for the installation of the stroke adjustment seat and the adjustment of its position. After the telescopic end of the telescopic mechanism 430 is moved by 11mm in a direction away from the lateral support seat 420, a space of 5mm is left in the second preformed hole 410-1 for installing other structures to prevent interference.
The height of the male shoulder structure 442-2 is 4mm and the length of the link block 481 at the lower end of the stroke adjustment seat 480 is 10mm. After the installation is completed, the distance between the linkage block 481 and the outer convex shoulder structure 442-2 is 0.5-1 mm, so that interference clamping stagnation during movement is avoided. When the telescopic end of the telescopic mechanism 430 moves away from the lateral support seat 420, the outer convex shoulder structure 442-2 can push the linkage block 481 to retreat together with the sliding plate 410 and the mounting plate 490, so as to realize the loosening action of the oil sprayer body 10.
The inclination degree of the bottom of the angle adjusting seat 450 is determined according to the deflection angle condition of the first cylindrical oil hole 10-1 for implementing high-pressure sealing in actual need, the angle range is between-45 degrees and 45 degrees, and the angle deflection of different angle adjusting seats 450 corresponds to the angle deflection of the first cylindrical oil hole 10-1 or the second cylindrical oil hole 10-4.
The lateral support seat 420 needs to be oriented according to the change of the inclination angle of the angle adjustment seat 450, so as to ensure that the lateral support seat 420 can accurately abut against the side portion of the fuel injector body 10. The end surface of the abutting end of the lateral supporting seat 420 is arc-shaped, and the arc-shaped is designed into an arc groove with the diameter of 26mm and is used for precisely fitting with the cylindrical surface of the fuel injector 10 to realize the supporting function.
The height of the first sealing seat 120 needs to match the depth of the concave end surface at the lower end of the oil sprayer body 10 and the height of the machine tool connecting seat 130, so that the high-pressure sealing of the oil path of the concave end surface at the lower end of the oil sprayer body 10 is realized, and the sealing between the first sealing seat 120 and the machine tool body 1 is ensured.

Referring to fig. 16 and 17, the present embodiment is different from the first embodiment in that the bottom of the angle adjusting seat 450 provided in the present embodiment is parallel to the plane of the machine bed 1.

This is applicable to the case where the oil jet body 10 is positioned in the longitudinal direction and the horizontal direction, and the second cylinder oil hole 10-4 is sealed and opened horizontally.
