According to the requirements of relevant regulations, VVT technology has become a standard configuration for passenger cars. When the engine is cold started, if there is a large lock pin clearance in the VVT, due to the lack of sufficient engine oil in the actuator driven by the phase to buffer, there is a high possibility of generating a short abnormal sound, which will have a certain impact on the user's comfort. In this case, a lock pin adjustment and measurement device was invented to control the lock pin clearance parameters during the production process of the VVT.
[0003] However, there are also certain problems with the existing testing devices. For example, for the phase shifter lock pin clearance adjusting device with the publication number CN206058908U, its positioning mechanism requires manual operation by technicians to position the phase shifter, with a low degree of automation and great room for improving work efficiency.

[0033] Embodiment:
[0034] As Figures 1 to 4As shown in the figure, a phase shifter lock pin clearance adjustment device includes a workbench 11. A processing table 32 is arranged on the workbench 11. A chassis 12 is rotatably connected to the workbench 11. The chassis 12 is located below the processing table 32. A fixing seat 13 for placing the phase shifter is fixedly arranged on the chassis 12. Automatic clamping mechanisms for fixing the sprockets on the phase shifter are symmetrically arranged on both sides of the fixing seat 13 on the chassis 12. The specific structure of the automatic clamping mechanism is as follows: The automatic clamping mechanism includes clamping blocks 17. Extension plates 18 are symmetrically arranged on the left and right on the chassis 12. The clamping blocks 17 are located on the extension plates 18. A first cylinder 19 for driving the clamping blocks 17 to move towards each other is installed on the extension plates 18. Tooth blocks 20 are fixedly connected to the opposite surfaces of the clamping blocks 17.
[0035] After the technician places the phase shifter on the fixing seat 13, the first cylinder 19 pushes the two clamping blocks 17 to move towards each other, so that the tooth blocks 20 are engaged with the sprockets of the phase shifter, so as to achieve the function of fixing the sprockets.
[0036] A positioning mechanism for fixing the stator of the phase shifter is arranged at the rear side of the processing table 32. The specific structure of the positioning mechanism is as follows: The positioning mechanism includes a top block 29. A second slide rail 30 is installed on the processing table 32. The top block 29 is slidably connected to the second slide rail 30 in the front-back direction. A fourth cylinder 31 for driving the top block 29 to slide back and forth is installed on the workbench 11.
[0037] After the sprockets are fixed, the fourth cylinder 31 drives the top block 29 to move forward until the top block 29 presses on the stator of the phase shifter, thereby locking the stator and preventing the sprockets from driving the stator to rotate.
[0038] A first driving mechanism for driving the chassis 12 to rotate is installed on the workbench 11. The specific structure of the first driving mechanism is as follows: The first driving mechanism includes a driving gear 15 driven by a motor (not shown in the figure). The driving gear 15 is rotatably connected to the workbench 11. A tooth surface 16 is formed on the front side surface of the chassis 12. The driving gear 15 is engaged with the tooth surface 16. After the sprockets are fixed, the driving gear 15 drives the chassis 12 to rotate by a certain angle, so as to adjust the lock pin clearance of the phase shifter to a suitable angle.
[0039] First slide rails 14 are symmetrically arranged on the left and right on the workbench 11. An assembly mechanism slides back and forth on the first slide rails 14 and is located above the chassis 12. After the lock pin clearance of the phase shifter is adjusted, the assembly mechanism performs an assembly operation on the phase shifter.
[0040] The specific structure of the assembly mechanism is as follows: The assembly mechanism includes a screw driver 21. A sliding frame 22 is slidably connected to the front and rear of the first slide rail 14. The screw driver 21 is installed on the sliding frame 22. A second air cylinder 23 for driving the sliding frame 22 to slide back and forth is installed on the workbench 11.
[0041] Moreover, a second driving mechanism for driving the screw driver 21 to move left and right is installed on the screw driver 21. The specific structure of the second driving mechanism is as follows: The second driving mechanism includes a lead screw 24. An installation cavity 25 with an opening facing forward is formed in the screw driver 21. The lead screw 24 is rotatably connected to the installation cavity 25. A sliding plate 26 is threadedly connected to the lead screw 24. A cross plate 27 is installed on the sliding plate 26. The screw driver 21 is installed on the cross plate 27. A third air cylinder 28 for driving the cross plate 27 to move up and down is installed on the sliding plate 26.
[0042] It should be noted that in this embodiment, a large number of mature technologies support the functions to be realized by the screw driver 21. The essence of the present utility model lies in optimizing and combining the connection modes of existing hardware machines for specific application scenarios to adapt to the problem of tightening the screws on the phase shifter (without changing the internal structure of the screw driver 21).
[0043] Through the above structure, the screw driver 21 can be moved in four directions of front, back, left and right, so that after the locking pin clearance of the phase shifter is adjusted, the screws on the phase shifter can be tightened, thus completing the assembly work of the phase shifter.
[0044] In addition, a number of universal wheels 33 are installed below the workbench 11 to facilitate technicians to move the phase shifter locking pin clearance adjustment device, so that the phase shifter locking pin clearance adjustment device can adapt to different working environments.
[0045] At the same time, it should be pointed out that the terms used in the present utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation on the protection scope of the present utility model.
[0046] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
