Detailed Description
The invention is further described below with reference to examples, but not to be construed as being limited thereto, and any number of modifications which can be made by anyone within the scope of the claims are also within the scope of the claims.
Referring to fig. 1-2, the fuel injection pump gear drawing tool provided by the invention comprises a base 1 and a drawing bolt 2. The bottom of base 1 is equipped with and is used for pegging graft bellied inserting groove 3 in the middle of oil spout pump impeller 13 to make the terminal surface of base 1 and the terminal surface laminating of oil spout pump impeller 13, the middle arch of protection oil spout pump impeller 13. The base 1 is provided with a plurality of mounting holes 4 corresponding to the threaded holes of the oil injection pump wheel 13, and positioning bolts 5 are arranged in the mounting holes 4. The base 1 can be fixed to the injection pump wheel 13 by means of the positioning screws 5. The top of base 1 is equipped with rather than the extension seat 6 of formula structure as an organic whole, is equipped with a screw 7 that link up inserting groove 3 in the extension seat 6, draws bolt 2 and installs in screw 7. Lengthening seat 6 is used for drawing bolt 2 more firm the installation on base 1, has also reduced the whole weight of this frock simultaneously. In order to enable the tool to be easier and more labor-saving in the operation process, the base 1 is designed to be thinner, but the problem that the screw hole 7 is shallower, and the problem of drawing failure is caused by the fact that a wire is easy to slide; however, if the base 1 is lengthened, the tool is heavier and is not beneficial to operation. In order to solve the problem, the depth of the screw hole 7 is increased by adding the lengthening seat 6 above the base 1, so that the drawing bolt 2 is more firmly installed on the base 1, and the overall weight of the tool is effectively reduced. The drawing bolt 2 is used for drawing the base 1 so as to take out the oil jet pump impeller 13. When the oil injection pump is used, the end part of the drawing bolt 2 is tightly propped against the rotating shaft of the oil injection pump, and the drawing bolt 2 is rotated to enable the base 1 to move outwards, so that the oil injection pump wheel 13 can be taken out. The oil injection pump wheel 13 dismounting device is simple and convenient to operate, time-saving, labor-saving and high in efficiency, can be used for dismounting the oil injection pump wheel 13 quickly, can also prevent the oil injection pump wheel 13 from being damaged, and effectively protects the oil injection pump wheel 13.
The mounting hole 4 of this embodiment is a through hole, and the positioning bolt 5 is inserted into the mounting hole 4, so that the base 1 can be quickly fixed on the oil injection pump impeller 13. The positioning bolt 5 is a half-thread bolt, and the cylindrical end of the half-thread bolt is positioned in the mounting hole to protect the mounting hole 4.
Preferably, inserting groove 3 is the tapered slot, and its tank bottom notch is big to it is protruding in the middle of oil spout pump impeller 13 that the cup joint that makes inserting groove 3 can be quick, makes base 1 install on oil spout pump impeller 13 more fast, improves work efficiency.
Referring to fig. 3, the end of the draw bolt 2 is provided with a post 8. Specifically, the column 8 and the drawing bolt 2 are of an integrated structure. The column 8 is provided with a protection component. Because drawing bolt 2 and tightly propping in the pivot of injection pump, drawing the 2 pivoted in-process of bolt, the pivot is immovable, consequently, draw the terminal surface of bolt 2 terminal surfaces on the screw thread breach scrape the flower or even scrape the blank with the terminal surface of pivot easily, not only influenced the outward appearance of pivot, serious still influenced the performance of pivot. In order to solve the problems, a cylinder is arranged at the end part of the drawing bolt 2, and the rotating shaft is protected by a protection component on the cylinder 8, so that the damage to the rotating shaft caused by the direct contact of a thread notch on the end surface of the drawing bolt 2 and the rotating shaft is avoided.
The protection component of this embodiment includes bearing 9, and cylinder 8 pegs graft in bearing 9, and the terminal surface of cylinder 8 does not bulge in the terminal surface of bearing 9. Namely, the cylinder 8 is inserted into the inner ring of the bearing 9, so that the rotating surface of the drawing bolt 2 does not directly contact with the rotating shaft when rotating; the outer lane and the pivot contact of bearing 9 for the tight power in top that will draw the in-process and draw bolt 2 production acts on the pivot through the bearing 9 outer lane, not only effectually draws oil spout pump impeller 13, has still avoided drawing bolt 2 and has directly contacted with the pivot in its rotor plane when rotating, better protection the pivot. Preferably, a conical body 10 is arranged between the drawing bolt 2 and the column 8, and the column 8 and the conical body 10 are inserted into the inner ring of the bearing 9. The bearing 9 can be firmly clamped at the end part of the drawing bolt 2 through the conical body 10, and the condition that the bearing 9 falls to hurt people or the bearing 9 is damaged due to the fact that the bearing 9 is not firmly fixed when the tool is disassembled and assembled is avoided.
Referring to fig. 4, the protection assembly further includes a mounting base 11. A stepped groove 12 is arranged in the mounting seat 11, the bearing 9 is mounted in the stepped groove 12, and one end face of the outer ring of the bearing 9 is in contact with the stepped surface of the stepped groove 12. The end surface fall of the inner ring and the outer ring of the conventional bearing 9 is small, the drawing force is different in the process of drawing different machine types, and when the drawing force is large, the jacking force acting on the bearing 9 is also large, so that the inner ring of the bearing 9 is easy to jack out and is directly contacted with the rotating shaft. In order to prevent the occurrence of the situation, the outer ring of the bearing 9 is supported through the mounting seat 11, so that when the inner ring is pressed down, the inner ring falls into the stepped groove 12, the contact between the inner ring and the rotating shaft is avoided, and the reliability of the tool is greatly improved.
Preferably, the bottom of the mounting seat 11 is provided with anti-slip lines arranged along the radial direction of the mounting seat 11 to further prevent the mounting seat 11 from rotating, so that the mounting seat 11 is more stably positioned on the rotating shaft.
Referring to fig. 5, the working principle of the present invention is: the drawing bolt 2 is arranged in a screw hole 7 of the base 1, then the bearing 9 is tightly clamped on the column body 8, and then the bearing 9 is arranged in the mounting seat 11; placing the base 1 on the oil injection pump impeller 13, enabling the mounting seat 11 to be in contact with the rotating shaft, ensuring that the middle bulge of the oil injection pump impeller 13 is inserted in the insertion groove 3, and enabling the mounting holes 4 on the base 1 to correspond to the threaded holes on the oil injection pump impeller 13 one by one; and screwing the positioning bolt 5 into the threaded hole to complete the installation of the base 1. When a tool such as a wrench is used to rotate the drawing bolt 2, the drawing bolt 2 drives the base 1 to move outwards through the reaction jacking force of the bearing 9 and the mounting seat 11 on the rotating shaft, so that the oil injection pump wheel 13 is driven to move outwards, and the oil injection pump wheel 13 falls off from the rotating shaft.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various changes and modifications without departing from the structure of the invention, which will not affect the effect of the invention and the practicability of the patent.
