2, gland extension elongation is controlled by the utility model device, ensure the fit dimension of each parts, improve assembly quality;
3, the utility model adopts bridge structure, and stability is high, and installation accuracy is high, and cost of manufacture is cheap, effective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.As shown in Figure 1, a kind of erecting device of natural gas engine high-voltage line gland, comprises and strikes bar 1 and base 2, it is characterized in that: described base 2 is made up of transverse arm 21, abutment sleeve 22 and two cylindrical positioning pins pin 23; Described cylindrical positioning pins pin 23 is vertically fixed on transverse arm 21 two ends, locates and fixed length for gland 3; Described abutment sleeve 22 is concentric with gland 3 installing hole 31, for being socketed gland 3; By bridge structure, strike bar 1 described in utilization and gland is knocked in installing hole 31.
Further, described transverse arm 21 is symmetrical arranged 3 locating holes 24, the locating hole 24 of both sides is provided with cylindrical positioning pins pin 23, and interfix hole 24 is provided with abutment sleeve 22, and described cylindrical positioning pins pin 23 and abutment sleeve 22 adopt welding manner to install connection; Described abutment sleeve 22 internal diameter is equal with gland 3 external diameter; There is annular knurl on described bar 1 surface of striking, for increasing frictional force, and slippage when preventing from using; Described bottom, bar 1 lower surface of striking arranges cylindrical sleeve convex 11, and the diameter of described cylindrical sleeve convex 11 is equal with gland 3 upper-end inner diameter, for being socketed gland 3 upper end; Described bar 1 lower surface of striking is parallel with transverse arm 21 upper surface; Described abutment sleeve 22 upper surface is equal with the length that gland 3 stretches out installing hole 31 with the vertical length between cylindrical positioning pins pin 23 lower surface; Described cylindrical positioning pins pin 23 is the cylinders of two ends with boss 231, and the boss 231 at two ends is installed in the location notch hole 41 that carries in transverse arm locating hole 24 and on cylinder cap respectively.
During assembling, first abutment sleeve 22 being enclosed within from top to bottom on transverse arm 21 interfix hole 24, adopting welding manner to connect, for ensureing the machining accuracy of abutment sleeve 22 upper surface, after having welded, carrying out Surface Machining and process again; Then cylindrical positioning pins pin 23 is inserted in from lower to upper in transverse arm about 21 two locating holes 24, welding manner is adopted to connect, after integral solder completes, need to ensure that abutment sleeve 22 upper surface meets the requirements to the dimensional accuracy of cylindrical positioning pins pin 23 lower end boss 231.
During use, cylindrical positioning pins pin 23 on base 2 is inserted on two location notch holes 41 that cylinder cap is chosen, by gland 3 through abutment sleeve 22, be inserted on gland 3 installing hole 31 on cylinder cap, then will strike bar 1 lower end cylindrical sleeve convex 11 and be inserted in the upper end of gland 3, and use hammer to knock bar 1 gently, gland 3 is pressed in installing hole 31, overlap until strike bar 1 lower end with abutment sleeve 22 upper end, gland 3 is in place.
