DETAILED DESCRIPTION

[0028] Embodiment 1:

[0029] A modular test bench for a hydraulic lock with a locking ring moving in a vertical direction, such as Figure 3 As shown, it includes an installation module 1, a front bracket module 6 and a rear bracket module 7 which are arranged in sequence from front to back; the installation module 1 is installed with a product lock, and a connecting rod module 4 is rotatably installed on one side through a support module 3; the front bracket module 6 and the rear bracket module 7 are respectively installed with a connection module 8 and a hydraulic loading cylinder, a spring loading module 5 is arranged between the connection module 8 and the hydraulic loading cylinder, and a lock ring module 2 and a tension pressure sensor are arranged between the connection module 8 and the product lock. Each of the above modules can be designed and manufactured separately, and the modules are combined by bolts to form a hydraulic lock performance test bench. Specifically, as Figure 1 and Figure 2 As shown, the lock ring diameter of the product lock is 12mm, the lock ring installation range L=3mm, and the lock ring rotation radius is 212.5mm.

[0030] During the test, the product lock is fixed to the installation module 1, and the left and right limit positions required by the product are ensured by adding or removing two adjustment pads 14 in the installation module 1; the front bracket module 6 and the rear bracket module 7 provide stable support for the test bench. The lock ring module 2 simulates the diameter and motion trajectory of the product lock ring, and moves in an arc trajectory after installation; the support module 3 and the connecting rod module 4 ensure the motion trajectory; the spring loading module 5 provides the lock ring to apply a linear tensile load to the lock hook; the connection module 8 connects the tensile pressure sensor and the hydraulic loading cylinder.

[0031] Preferably, if Figure 4 and Figure 5As shown, the mounting module 1 includes a mounting plate 11, a mounting seat 12 and a support 13. Supports 13 are respectively installed on both sides of the mounting plate 11, a product lock is installed between adjacent supports 13, and a mounting seat 12 is provided at the end of the mounting plate 11, and the mounting seat 12 is connected to the end of the product lock; the upper part of the support 13 is provided with a mounting groove with one side opening corresponding to the connecting rod module 4, and a connecting rod module 4 is inserted between adjacent mounting grooves, and the connecting rod module 4 is connected to the mounting groove through a first bearing 24. Further, the mounting module 1 also includes an adjustment pad 14, and adjustment pads 14 are respectively provided on both sides of the bottom of the mounting plate 11 for adjusting the left and right limit positions of the product lock. Specifically, for different design batches, according to the hydraulic lock products with different mounting hole positions, the mounting plate 11 is redesigned and manufactured, and the mounting module 1 can be replaced during testing.

[0032] Preferably, if Figure 6 As shown, the locking ring module 2 includes a seat body 21, a connecting support 22 and a connecting pin 23. U-shaped grooves are respectively provided on both sides of the seat body 21. The connecting rod module 4 passes through the U-shaped groove on one side of the seat body 21, and the connecting pin 23 passes through the U-shaped groove on the other side of the seat body 21; one end of the connecting support 22 extends into the U-shaped groove on the other side of the seat body 21, and is sleeved and installed on the outside of the connecting pin 23. One end of the connecting support 22 is rotatably connected to the connecting pin 23 through a second bearing 25; the other end of the connecting support 22 is connected to the loading mechanism through a tension and pressure sensor. Specifically, the seat body 21 is connected to the connecting rod module 4 and the connecting pin 23 through bushings. For different types of locks with vertical movement directions of the locking ring, it is only necessary to redesign the bushing with the corresponding diameter according to the diameter of the locking ring of different product locks, and replace the bushing of the locking ring module 2 during the test.

[0033] Two types of bearings are used in the structure of the locking ring module 2, among which the function of the first bearing 24 is to reduce the friction force as much as possible when simulating the movement of the locking ring; the function of the second bearing 25 is: the force provided by the hydraulic loading cylinder in the test bench is always in the axial direction, but when simulating the circular motion of the locking ring, a radial component force will be generated. If the second bearing 25 is not added here, but the overall structure is used, the locking ring module 2 will be damaged; adding the second bearing 25 can share the radial component force.

[0034] Preferably, if Figure 7As shown, the support module 3 includes a crossbeam and a support column. The crossbeam is fixedly connected to the bottom of the mounting plate 11, and one end of the support column passes through the mounting plate 11 and is connected to the crossbeam, and the other end is rotatably connected to the connecting rod module 4. For hydraulic lock products with different arc radii of the locking ring movement, the support rod and the connecting rod module 4 are redesigned, and the support module 3 and the connecting rod module 4 can be replaced during the test. The support module 3 is fixed to the mounting module 1 by screws, and the connecting rod module 4 is connected by a third bearing 41 to ensure the arc radius of the simulated locking ring movement, thereby reducing the friction between the connecting rod module 4 and the support module 3 during the movement. For different types of locks with vertical locking ring movement directions, it is only necessary to change the connecting rod module 4 and the support module 3 according to the different arc radii of the locking ring movement to ensure the radius requirements.

[0035] Preferably, if Figure 8 and Fig.11 As shown, the spring loading module 5 includes a loading spring 51, a connecting shaft 52, a guide shaft 53, a limit plate 54 and a driving plate 55. The limit plate 54 and the driving plate 55 are arranged in parallel. The guide shafts 53 are respectively installed on both sides of the limit plate 54 and the driving plate 55. A loading spring 51 is arranged between the limit plate 54 and the driving plate 55. One end of the connecting shaft 52 passes through the limit plate 54 and is sleeved with the loading spring 51. The other end of the connecting shaft 52 is connected to the tension pressure sensor through the connecting module 8, and the driving end of the hydraulic loading cylinder is connected to the driving plate 55. For hydraulic lock products with different linear tensile loads applied by the lock ring to the lock hook, the corresponding spring can be replaced, and the spring loading module 5 can be replaced during the test.

[0036] Preferably, a limiting end is provided at one end of the connecting shaft 52, a loading spring 51 is provided between the limiting end and the limiting plate 54, a limiting hole is provided on the limiting plate 54 corresponding to the connecting shaft 52, and bushings are respectively provided between the limiting hole and the connecting shaft 52 and between the loading spring 51 and the connecting column.

[0037] The front end of the spring loading module 5 is connected to the tension pressure sensor, and the rear end is connected to the hydraulic loading cylinder, wherein the spring parameters meet the linear tension load applied by the lock ring to the lock hook during the locking process, that is, the linear load force that the spring needs to generate within the compression stroke, to ensure the test requirements. At the same time, there are two bushings in the design of the spring loading module 5, the purpose is to prevent the risk of coiling after the spring is over-compressed. For different types of locks with vertical movement directions of the lock ring, it is only necessary to replace the corresponding spring according to the size of the linear tension load applied by the lock ring of different types of locks on the lock hook.

[0038] Furthermore, if Figure 9-11As shown, a rear support plate 71 is provided in the middle of the rear support module 7, and a mounting hole is provided on the rear support plate 71 corresponding to the driving end of the hydraulic loading cylinder, and the driving end of the hydraulic loading cylinder passes through the mounting hole and is connected to the driving plate 55.

According to the different movement directions of the lock rings of the product locks, it is only necessary to distinguish the same modules from the different modules. The same modules can be borrowed and the different modules can be redesigned and manufactured. The design of the lock test bench can be completed quickly, and the present invention has good practicality.
