DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment 1 is as follows Figure 1-2 As shown, the present utility model provides a technical solution: a fixture for an engine left vibration isolation pad assembly, including a lower backing plate 1, a guide sleeve 2, and an upper backing plate 6. A plurality of guide sleeves 2 are installed at the top end of the lower backing plate 1, and a plurality of slots 10 are opened inside the guide sleeves 2. A guide post 5 is provided at the top end of the guide sleeve 2, and an upper backing plate 6 is installed at the top end of the guide post 5. A fixed shaft 9 passing through the guide sleeve 2 is installed at the bottom end of the guide post 5, and a limiting mechanism for adjusting the distance between the upper backing plate 6 and the lower backing plate 1 is arranged inside the fixed shaft 9. The limiting mechanism includes a positioning shaft 11 and a limiting block 12. The positioning shaft 11 is installed at the bottom end of the fixed shaft 9, and the limiting blocks 12 penetrating through the slots 10 are installed on both sides of the outer wall of the positioning shaft 11. A rigid spring 13 is sleeved on the outer wall of the positioning shaft 11, and both sides of the rigid spring 13 are connected to the outer wall of the limiting block 12. A threaded hole is arranged inside the guide post 5, and a T-rotating shaft 14 is arranged inside the threaded hole. A threaded layer 15 adapted to the threaded hole is arranged on the outer wall of the T-rotating shaft 14. A tapered block 16 adapted to the limiting block 12 is installed at the bottom end of the T-rotating shaft 14. By driving the fixed shaft 9 to insert into the inner wall of the guide sleeve 2 through the guide post 5, and by rotating the T-rotating shaft 14 to drive the tapered block 16 to squeeze the limiting block 12, and at the same time the rigid spring 13 is stretched, so that the limiting block 12 is inserted into the slots 10 at a suitable position, which is convenient for adjusting the distance between the upper backing plate 6 and the lower backing plate 1.

[0021] Embodiment 2 is as follows Figure 1-4 As shown, the present utility model provides a technical solution: a fixture for an engine left vibration isolation pad assembly, including a limiting frame 7 installed at the bottom end of the upper backing plate 6, and a pulling plate 8 installed on one side of the limiting frame 7. A first positioning block 3 is provided at the top end of the lower backing plate 1, and a second positioning block 4 is provided at the top end of the lower backing plate 1. Threaded grooves are opened on the inner walls of the pulling plate 8 and the limiting frame 7, and a screw rod 17 is arranged inside the threaded grooves. By inserting the first positioning block 3 and the second positioning block 4 into the top position of the lower backing plate 1, the position of the vibration isolation pad assembly is fixed. By rotating the screw rod 17 to engage with the inner wall of the limiting frame 7, the vibration isolation pad assembly is inserted into the groove position of the limiting frame 7. At this time, the screw rod 17 can be rotated through the through hole of the vibration isolation pad assembly until it contacts one side of the limiting frame 7, and then the clamping and fixing can be completed.
