[0027] The following will describe in detail the specific embodiments of the present utility model with reference to the drawings. It should be understood that the specific embodiments described herein are only for explaining and illustrating the present utility model, and are not used to limit the present utility model.

[0028] As Figure 1 , Figure 2 and Figure 3 shown, the present utility model provides a tooling for installing a process flywheel 1, and this tooling is used to install the process flywheel 1 to the end of the engine crankshaft 2.

[0029] The tooling includes a support base 10 and a support member 20. The support member 20 is disposed on the support base 10. The support member 20 is used to support the process flywheel 1 and can make the axis line of the process flywheel 1 extend in the horizontal direction, and can make the axis line of the process flywheel 1 and the axis line of the engine crankshaft 2 be in the same horizontal plane. The support base 10 is arranged to be movable in the direction towards the engine crankshaft 2 so that the axis line of the process flywheel 1 is aligned with the axis line of the engine crankshaft 2. The process flywheel 1 is arranged to be movable on the support member 20 so that the stop 101 of the process flywheel 1 is close to the end face of the engine crankshaft 2 and can be locked and fixed by bolts.

[0030] In the technical solution provided by the present invention, the support member 20 disposed on the support base 10 supports the process flywheel 1 to be installed, and when supporting, the axis line of the process flywheel 1 extends in the horizontal direction. By moving the support base 10 close to the engine crankshaft 2, the axis line of the process flywheel 1 can be aligned with the axis line of the engine crankshaft 2. Then, the process flywheel 1 is moved in the direction towards the engine crankshaft 2 so that its stop 101 can be close to the end face of the engine crankshaft 2, so that the process flywheel 1 can be conveniently locked and fixed on the end face of the engine crankshaft 2 by bolts.

[0031] Through the tooling provided by the present invention, the labor force in the installation process of the process flywheel 1 is greatly saved. Through practical verification, at least one operator can be reduced, and the labor intensity of the operator can be significantly reduced. In addition, when installing the process flywheel 1 through the tooling of the present invention, only need to hold the support base 10 to align the axis line of the process flywheel 1 on the support member 20 with the axis line of the engine crankshaft 2, and then push the process flywheel 1 to abut against the end of the engine crankshaft 2, and then it can be locked and fixed by bolts. It is simple and convenient, and the tooling can significantly improve the installation efficiency of the process flywheel 1.

[0032] It should be noted that in the engine test bench involved in the present invention, the distance between the center of the engine crankshaft 2 and the ground is certain. Based on this characteristic, by setting the distance between the support member 20 of the tooling of the present invention and the ground to be the same as the distance between the center of the engine crankshaft 2 and the ground, it can be ensured that the tooling has good versatility. That is, the support member 20 and the engine crankshaft 2 are at the same height. In this way, when the support base 10 moves, the axis line of the process flywheel 1 supported on the support member 20 can be aligned with the axis line of the engine crankshaft 2. Exemplarily, the vertical distance between the support member 20 and the ground is 800 mm.

[0033] In some embodiments, the tooling further includes at least one guide rod 30. One end of the guide rod 30 is detachably installed in the threaded hole 201 at the end of the engine crankshaft 2, and the other end of the guide rod 30 is used to insert into the mounting and fixing hole 102 of the process flywheel 1.

[0034] It should be noted that, as shown in Figure 4 In the present utility model, a plurality of mounting and fixing holes 102 are provided on the process flywheel 1. The plurality of mounting and fixing holes 102 correspond one-to-one with the plurality of threaded holes 201 provided at the end of the engine crankshaft 2 and are respectively locked and fixed by bolts, that is, the mounting and fixing of the process flywheel 1 at the end of the engine crankshaft 2 is realized. In the embodiment of the present utility model, by installing the guide rod 30 in the threaded hole 201 at the end of the engine crankshaft 2, and the other end of the guide rod 30 is used to insert into the mounting and fixing hole 102 of the process flywheel 1. When the support base 10 drives the process flywheel 1 to be installed and moves in the direction towards the engine crankshaft 2, by inserting the guide rod 30 into the mounting and fixing hole 102 of the process flywheel 1, the process flywheel 1 can be guided, so that its axis can be aligned with the axis of the engine crankshaft 2 more quickly; when the process flywheel 1 is locked and fixed to the end of the engine crankshaft 2 by bolts, the guide rod 30 can also play a certain supporting role. After the remaining mounting and fixing holes 102 and threaded holes 201 between the process flywheel 1 and the engine crankshaft 2 are all locked and fixed by bolts, the guide rod 30 is removed from the end of the engine crankshaft 2, and then the threaded hole 201 where the guide rod 30 is located and the corresponding mounting and fixing hole 102 are locked and fixed by bolts.

[0035] In the present utility model, the number of the guide rods 30 can be set according to actual needs. Exemplarily, two guide rods 30 are provided. In this way, it will not be difficult to insert into the mounting and fixing holes 102 of the process flywheel 1 due to too many guide rods 30, nor will it be unable to effectively guide the process flywheel 1 due to too few guide rods 30. Further preferably, the two guide rods 30 are symmetrically arranged at the end of the engine crankshaft 2.

[0036] In the present utility model, the support member 20 can be of any appropriate structural form, as long as it can support the process flywheel 1 to be installed and make its axis extend in the horizontal direction. In some embodiments, the support member 20 is a rod-shaped member extending in the horizontal direction. One end of it is fixed on the support base 10, and the other end extends in the direction away from the support base 10. By passing the rod-shaped support member 20 through the central hole 103 of the process flywheel 1, the support of the process flywheel 1 can be realized, and the axis of the process flywheel 1 can be made to extend in the horizontal direction.

[0037] In some embodiments, a guiding block 21 is provided at one end of the supporting member 20 facing away from the supporting seat 10. The guiding block 21 is used to guide the supporting member 20 to align with the end of the engine crankshaft 2. Further, the guiding block 21 is made of nylon. Through the above arrangement, when the process flywheel 1 to be installed approaches the engine crankshaft 2, it is avoided that the supporting member 20 directly contacts and collides with the end of the engine crankshaft 2, that is, the guiding block 21 can also play a role in protecting the end of the engine crankshaft 2.

[0038] In some embodiments, a pin hole 22 is provided on the supporting member 20, and a safety pin is provided in the pin hole 22 to prevent the process flywheel 1 from falling off. During the movement and storage of the process flywheel 1, the safety pin is inserted into the pin hole 22 to prevent the process flywheel 1 from falling off.

[0039] In the present utility model, as a specific implementation manner of the supporting seat 10 moving in the direction close to the engine crankshaft 2, rollers 11 are provided at the bottom of the supporting seat 10. More specifically, in the present utility model, the roller 11 on the side of the supporting seat 10 close to the engine crankshaft 2 is set as a directional wheel, and the roller 11 on the side of the supporting seat 10 facing away from the engine crankshaft 2 is set as a universal wheel. Through the above arrangement, it is convenient to control the direction during the movement of the supporting seat 10, so that the axis line of the process flywheel 1 on the supporting member 20 can be aligned with the axis line of the engine crankshaft 2 more quickly. Exemplarily, four rollers 11 are provided at the bottom of the supporting seat 10, and the load capacity of each roller 11 is 80 kg, so as to meet the support requirements of the process flywheel 1 used in some heavy-duty emission test benches.

[0040] In some embodiments, the supporting seat 10 includes a bottom plate 12 and a vertical rod 13. At least one vertical rod 13 is provided and is set to extend upward from the bottom plate 12. One end of the supporting member 20 is fixed on the vertical rod 13, and the other end of the supporting member 20 extends horizontally in a direction away from the vertical rod 13. In a specific implementation manner of the present utility model, in combination with Figure 1 As shown, two vertical rods 13 are provided. The two vertical rods 13 extend upward from both sides of the bottom plate 12 respectively. A cross bar 132 is provided between the two vertical rods 13. One end of the supporting member 20 is fixed on the cross bar 132, and support rods 133 extending downward are respectively provided on both sides of the connection position of the cross bar 132 and the supporting member 20. The lower ends of the support rods 133 are fixed on the bottom plate 12.

[0041] In some embodiments, in combination with Figure 1 and Figure 2As shown, the support seat 10 further includes an inclined tie rod 14, one end of which is fixed to the rod body of the vertical rod 13, and the other end of which is fixed to the base plate 12. It can be understood that by providing the inclined tie rod 14, the support seat 10 is prevented from tilting or tipping over due to unstable center of gravity during movement. In a further preferred embodiment, a counterweight structure can be further provided on one side of the inclined tie rod 14 connected to the base plate 12 to improve the stability of the support seat 10.

[0042] It should be noted that, in the present invention, a friction plate 3 is provided between the process flywheel 1 and the end of the engine crankshaft 2, and the friction plate 3 can reduce the oil leakage at the end of the engine crankshaft 2, while ensuring the effective transmission of torque, so as to achieve the purpose of reducing energy consumption and reducing pollution. According to the current process requirements, the friction plate 3 must be replaced every time the process flywheel 1 is installed on the upper and lower platforms of the heavy-duty engine to ensure that there is no oil leakage and the effective transmission of power. Based on this, in some embodiments of the present invention, the vertical pole 13 is provided with a first storage box 40 and a second storage box 50, the first storage box 40 is used to store new friction plates, and the second storage box 50 is used to store old friction plates; since the removed friction plates 3 are stained with oil, the old friction plates 3 are stored in the independently provided second storage box 50 to prevent the old friction plates 3 from being randomly placed and causing pollution; in addition, by arranging the old friction plates 3, it is also convenient to count the consumption of the friction plates 3 in the future.

[0043] In some embodiments, in combination Figure 1 and Figure 2 As shown, a handle 15 is provided at the upper end of the vertical rod 13. When the tooling of the utility model is actually used, the operator can use the handle 15 to push the support base 10 to move. Exemplarily, two vertical rods 13 are provided, and the upper halves of the two vertical rods 13 are respectively provided with oblique support rods 151 extending obliquely upward, and the handle 15 is installed between the upper ends of the two oblique support rods 151.

[0044] In some embodiments, a placement hole 131 is provided at the top of the vertical pole 13, and the placement hole 131 is extended along the length direction of the vertical pole 13. In the present invention, by providing the placement hole 131 at the top of the vertical pole 13, the placement hole 131 can be used to place the guide rod 30, so that the guide rod 30 can be placed in a more conspicuous position to avoid the loss of the guide rod 30. More specifically, a threaded structure is provided on the hole wall of the placement hole 131, and the guide rod 30 can be screwed and fixed in the placement hole 131.

[0045] In some embodiments, enclosing plates 16 extending upward are respectively arranged around the bottom plate 12, and an open storage space 60 is formed by enclosing the enclosing plates 16 and the bottom plate 12. It can be understood that by making full use of the upper space of the bottom plate 12 and cooperating with the enclosing plates 16 extending upward around it to form the storage space 60, this storage space 60 can be used to store tools and can be conveniently accessed when needed.

[0046] The process of installing the process flywheel 1 to the end of the engine crankshaft 2 by using the tooling of the present utility model is described below to enable those skilled in the art to more clearly understand the advantages of the tooling of the present utility model.

[0047] First, two guide rods 30 are installed at the end of the engine crankshaft 2, and the two guide rods 30 are screwed and fixed in the threaded holes 201 at the end of the engine crankshaft 2 by manual tightening; specifically, when selecting, the two guide rods 30 can be installed in two threaded holes 201 in the up-down direction or the left-right direction; then, a new friction plate 3 is installed at the end of the engine crankshaft 2, and a plurality of through holes are provided on the friction plate 3 for corresponding to a plurality of threaded holes 201 at the end of the engine crankshaft 2 one by one. During the installation process of the friction plate 3, the two guide rods 30 respectively pass through two through holes on the friction plate 3; then, the support seat 10 supporting the process flywheel 1 is moved in the direction towards the engine crankshaft 2, so that the two guide rods 30 respectively pass through two mounting and fixing holes 102 on the process flywheel 1, and then continue to push the support seat 10 until the process flywheel 1 is in place. Here, being in place means that the stop 101 of the process flywheel 1 is engaged with the end face stop of the engine crankshaft 2, meeting the condition for installing and tightening the bolts; then, install the bolts between the process flywheel 1 and the engine crankshaft 2. At this time, the remaining six bolts can be installed first and pre-tightened, then the two guide rods 30 are removed, the bolts are reinstalled, and then the support seat 10 is pushed away from the engine crankshaft 2, that is, the installation operation of the process flywheel 1 is completed.

[0048] The removal operation of the process flywheel 1 can be performed in reverse order according to the above steps. Specifically, first remove two relatively arranged bolts, install two guide rods 30, then push the tooling closer so that the support member 20 is inserted into the central hole 103 of the process flywheel 1, and then remove the remaining six bolts. At this time, the process flywheel 1 is disconnected from the end of the engine crankshaft 2, and the operator holds the process flywheel 1 by hand and moves the tooling in the direction away from the engine crankshaft 2, then the process flywheel 1 can be disassembled.

[0049] The tooling provided by the present utility model can be widely applied to the rapid installation of the process flywheel 1 in the engine bench test, and is also convenient for the management and storage of the process flywheel 1 on site, and can effectively improve the preparation efficiency before the engine enters the bench. Since the tooling has a simple structure, is movable, has high efficiency and high safety, and can also serve as a storage device for the process flywheel 1, it has broad application prospects in this field.
