[0002] Before the engine is sent to the vehicle assembly workshop, the hot test bench serves as the final testing station for the engine. It requires the assembly of many vehicle accessories (such as the process starter motor, process wiring harness, process ECU, process exhaust, process three-way catalytic converter, and process muffler) before testing. Installing the process starter motor requires manual tightening of process bolts, which is not only tedious but also inconvenient in some locations due to space constraints, resulting in low operational efficiency. Furthermore, the fast pace and high labor intensity can easily lead to operator fatigue, which is detrimental to safe production.

[0003] Therefore, it is necessary to develop an auxiliary device for assembling the process starter motor. Summary of the Invention

[0031] The invention will now be further described with reference to the accompanying drawings.

[0032] like Figures 1 to 10As shown in this embodiment, a process starter motor assembly auxiliary device includes a starter motor rotating block 1, a spring pin handle 3, a handle base 5, a spring pin 6, and a spring pin base 7. The lower part of one end of the starter motor rotating block 1 has a first mounting hole 1c for connecting to the process gearbox housing 12, and the lower part of the other end of the starter motor rotating block 1 has a first pin hole 1d that mates with the spring pin 6. The top surface of the starter motor rotating block 1 has a second mounting hole 1f for connecting to the process starter motor. The spring pin base 7 has a third mounting hole 7d for connecting to the process gearbox housing 12, and a second pin hole 7c that aligns with the first pin hole 1d on the starter motor rotating block 1. One end of the spring pin 6 can sequentially extend into the second pin hole 7c and the first pin hole 1d. The other end of the spring pin 6 is connected to one end of the spring pin handle 3. A limiting hole 3b is formed in the middle of the spring pin handle 3. One end of the handle base 5 has a fourth mounting hole 5a for connecting with the process gearbox housing 12, and the other end of the handle base 5 has a groove 5b and a locking pin hole 5c. The spring pin handle 3 can extend into the groove 5b and is limited by the handle locking pin 11 inserted into the locking pin hole 5c and the limiting hole 3b. Figure 9 As shown, two locking holes 11a are provided on the handle locking post 11, and a locking clip is inserted into the locking hole 11a for limiting.

[0033] like Figure 2 and Figure 3 As shown, in this embodiment, the starting motor rotating block 1 includes a horizontal mounting part 1a and two connecting parts 1b. The two ends of the horizontal mounting part 1a are respectively connected to the upper ends of the two connecting parts 1b. The first mounting hole 1c is opened at the lower end of one of the connecting parts 1b. The first pin hole 1d is opened at the lower end of the other connecting part 1b. There are two second mounting holes 1f, which are respectively opened on the horizontal mounting part 1a.

[0034] like Figure 4 and Figure 5 As shown, in this embodiment, the spring pin base 7 is T-shaped in general, and includes a horizontal part 7b and a vertical part 7a; the second pin hole 7c is opened on the vertical part 7a; and there are four third mounting holes 7d, which are respectively opened on the horizontal part 7b.

[0035] In this embodiment, the head of the spring pin 6 is in transition fit with the first pin hole 1d. The spring pin 6 is also in transition fit with the second pin hole 7c.

[0036] like Figures 6 to 8As shown, in this embodiment, the spring pin 6 has a groove 6a, the spring pin handle 3 has a connecting hole 3a, and the spring pin 6 and the spring pin handle 3 are connected together by a retaining pin through the groove 6a and the connecting hole 3a.

[0037] like Figure 1 As shown, in this embodiment, a rotating block handle 10 is also included. A fifth mounting hole 1e is provided on the horizontal mounting part 1a of the starter motor rotating block 1, and the rotating block handle 10 is mounted on the starter motor rotating block 1 through the fifth mounting hole 1e.

[0038] In this embodiment, the process starter motor is fixed to the starter motor rotating block 1 via the first mounting hole 1f using the third bolt 9. The starter motor rotating block 1 is connected to the process gearbox housing 12 via the first mounting hole 1c using a double-ended stud 2. The spring pin base 7 is connected to the process gearbox housing 12 via the third mounting hole 7d using the second bolt 8. The spring pin 6 passes through the second pin hole 7c on the spring pin base 7 and enters and exits the first pin hole 1d on the starter motor rotating block 1 to limit or release the starter motor rotating block 1. To facilitate operation, a spring pin handle 3 is designed. The connecting hole 3a on the spring pin handle 3 and the groove 6a on the spring pin 6 are connected and limited by a locking pin. The handle base 5 is connected to the process gearbox housing 12 via the fourth mounting hole 5a using the first bolt 4. The spring pin handle 3 can be limited by inserting a handle locking pin 11 into the limiting hole 3b and the locking pin hole 5c. The main function of the handle locking pin 11 is to partially limit the spring pin handle 3 on the handle base 7.

[0039] This device is designed solely for the auxiliary assembly of the process starter motor on the hot test bench. It utilizes the process gearbox housing 12 on the bench as a base, primarily considering two aspects: rotation and limiting. In this embodiment, both the starter motor rotating block 1 and the spring pin handle 3 are designed to be rotatable. The handle pin 11 can partially limit the spring pin handle 3. When the spring pin handle 3 is rotated, the spring pin 6 can be disengaged from the first pin hole 1d of the starter motor rotating block 1. At this time, the starter motor rotating block 1 can rotate. Since one end of the starter motor rotating block 1 is detached from the engine's process gearbox housing 12, the operating space around the engine increases, allowing the engine to be sent out of the hot test bench. After the next engine is properly connected to the starter gearbox housing 12, the starter motor rotating block 1 can be rotated again, and the holes aligned (i.e., the first pin hole 1d and the second pin hole 7c aligned). Then, the spring pin handle 3 is rotated, causing the spring pin 6 to insert into the first pin hole 1d of the starter motor rotating block 1. Finally, the handle pin 11 is inserted into the limiting hole 3b and the pin hole 5c to limit the spring pin handle 3. At this point, the starter motor is properly assembled and its limit is stable, allowing for smooth and quick assembly and disassembly of the starter motor.

[0040] In this embodiment, as Figure 11 and Figure 12 As shown, in the working state, the large end face of the engine block engages with the end face of the process transmission housing 12. The installed process starter motor and starter motor rotating block 1 are rotated upwards. After the starter motor rotating block 1 is rotated into position, the spring pin handle 3 is rotated, which drives the spring pin 6 to insert into the first pin hole 1d of the starter motor rotating block 1. Then, the handle pin 11 is inserted, which limits the starter motor rotating block 1 to the process transmission housing 12. At this time, the process starter motor can engage with the flywheel to start the engine. After the hot test, the handle pin 11 is removed, the spring pin handle 3 is rotated, and the spring pin 6 is brought out. The process starter motor is rotated downwards to the far end of the protective flange; thus completing the entire process starter motor installation and removal cycle.

[0041] This device can prevent engine starting difficulties caused by improperly installed starter motor bolts without interfering with the engine's process gearbox end face layout. It is simple in structure and easy to operate, which greatly reduces the operator's labor intensity. At the same time, it allows the operator to conduct more detailed inspection and confirmation of the engine hot test within the limited work station cycle time, control the outflow of unqualified products, and improve the factory pass rate.
