Abstract
The utility model relates to the technical field of engines, and discloses an auxiliary tool for installing a pressure limiting valve, which comprises a tool body, wherein a tightening column is sleeved in the tool body, and a bulge matched with a groove of the limiting valve is formed at the lower end of the tightening column; the tool body is sleeved with a locking screw. The pressure release valve can be conveniently screwed by an operator, the torque of the pressure release valve can be more favorably controlled, and the technical requirement is met.
Description
The technical field is as follows:
the utility model relates to the technical field of engines, concretely relates to auxiliary fixtures of installation pressure limiting valve.
Background art:
along with the development of the engine industry in China, the performance requirements on the diesel engine are higher and higher, the problems of various oil leaks and loosening of parts can be prevented only when the torque reaches the standard because the torque control requirements on the parts of the diesel engine in the assembling process are higher, and the competitiveness of the diesel engine in the industry can be improved only by improving the quality of the diesel engine of the company.
Because the pressure limiting valve can not be screwed directly by a torque wrench, the tightening column is required to be screwed for assisting in screwing, one hand is required to be used for vacating and holding, and the other hand is used for holding the wrench for screwing, so that inconvenience is brought to an operator.
The utility model has the following contents:
the utility model aims at overcoming prior art's not enough, providing an installation pressure limiting valve's auxiliary fixtures, it can make things convenient for the operation workman to screw up the relief valve, and more does benefit to control the relief valve moment of torsion, satisfies technical requirement.
The utility model provides a technical problem's scheme is:
an auxiliary tool for installing a pressure limiting valve comprises a tool body, wherein a tightening column is sleeved in the tool body, and a bulge matched with a groove of the limiting valve is formed at the lower end of the tightening column; the tool body is sleeved with a locking screw.
The tool body is formed with a through hole, a bushing is sleeved and fixed in the through hole, and the tightening column is inserted in the bushing.
Two clamping grooves which are arranged up and down are formed in the outer wall of the tightening column, and a clamp spring is sleeved in each clamping groove; two jump rings are located the upside and the downside of bush respectively.
A step through hole is formed in the tool body; the locking screw comprises a step cylinder, outer wall threads are formed at the large end of the step cylinder, and a knob part is fixed at the extending end of the small end of the step cylinder, which penetrates through the small end hole of the step through hole.
The length L of the large end part of the step column body is smaller than the depth H of the large end hole of the step through hole.
The number of the locking screws is two.
And a hexagonal column body is formed at the upper end of the tightening column.
The utility model discloses an outstanding effect is:
compared with the prior art, the pressure release valve can be screwed up by an operator conveniently, the torque of the pressure release valve can be controlled more conveniently, and the technical requirement is met.
Description of the drawings:
fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the present invention assembled with a piston, a connecting rod, etc.;
fig. 3 is a partially enlarged view of fig. 2 about a.
The specific implementation mode is as follows:
in an embodiment, as shown in fig. 1 to 3, an auxiliary tool for installing a pressure limiting valve comprises a tool body 1, wherein a tightening column 2 is sleeved in the tool body 1, and a protrusion 21 matched with a groove of the pressure limiting valve is formed at the lower end of the tightening column 2; the tool body 1 is sleeved with a locking screw 3.
Furthermore, a through hole 11 is formed in the tool body 1, a bushing 4 is sleeved and fixed in the through hole 11, and the tightening column 2 is inserted in the bushing 4.
Furthermore, two clamping grooves which are arranged up and down are formed in the outer wall of the tightening column 2, and a clamping spring 5 is sleeved in each clamping groove; two circlips 5 are respectively positioned at the upper side and the lower side of the bushing 4.
Furthermore, a step through hole 12 is formed on the tool body 1; the locking screw 3 comprises a step cylinder 31, an outer wall thread 32 is formed at the large end of the step cylinder 31, and a knob part 33 is fixed at the protruding end of the small end of the step cylinder 31 which passes through the small end hole of the step through hole 12.
Further, the length L of the large end of the stepped cylinder 31 is smaller than the depth H of the large end hole of the stepped through hole 12.
Furthermore, there are two locking screws 3.
Further, the upper end of the tightening cylinder 2 is formed with a hexagonal cylinder 22.
The working principle is as follows: the locking screw 3 is screwed on a side threaded hole of the pressure limiting valve installed on the machine body, so that the tool is fixed on the machine body; then insert the recess of relief valve with protruding 21, sheathe the sleeve on hexagonal cylinder 22, then rotate the sleeve with torque wrench or electric torque gun, the sleeve drives and screws up post 2 and rotate, screws up post 2 and screws up the relief valve, only needs one hand operation in this tightening process, and more stable.
Finally, the above embodiments are only used for illustrating the present invention, and not for limiting the present invention, and those skilled in the relevant art can make various changes and modifications without departing from the spirit and scope of the present invention, so that all equivalent technical solutions also belong to the scope of the present invention, and the protection scope of the present invention should be defined by the claims.
