Description

Technical Field

[0001] This utility model belongs to the field of testing device technology, specifically a high-precision compression testing device for marine titanium alloy welded joints. Background Technology

[0002] The high-precision compression testing device for marine titanium alloy welded joints is a specialized device for evaluating the mechanical properties of welded joints under compressive loads. It accurately measures the compressive strength of the welded joint using high-precision sensors. In terms of applications, this device can be used for ship structural safety assessment, verifying the load-bearing capacity of titanium alloy welded joints under extreme loads, and providing data support for hull structure design. It can also be used for materials research and certification, comparing the impact of different welding processes or heat treatment states on the compressive performance of joints. Furthermore, it can be used for failure analysis and life prediction, establishing a model of the relationship between joint life and load amplitude through compressive fatigue testing to guide the formulation of ship maintenance cycles.

[0003] An existing patent (publication number: CN219737077U) discloses a welding joint testing device. This testing device is equipped with a protective device. After the welding joint testing mechanism is fixedly connected to the connecting frame, the limiting sleeve at the bottom of the moving frame can fit against the outside of the line, ensuring the stability of the line structure after the welding joint testing mechanism and the connecting frame are installed, thus extending the service life of the device. However, after the welding joint compression test device is completed, workers need to intervene to unload and collect the material. The manual operation increases the workload and affects the continuity of processing. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a high-precision compression testing device for marine titanium alloy welded joints. It effectively solves the problem that existing welded joint compression testing devices require manual intervention for material unloading and collection after testing, which increases the workload and affects the continuity of processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision compression testing device for marine titanium alloy welded joints, comprising a workbench, an internal collection bucket, a support frame fixedly mounted on the top of the workbench, a hydraulic cylinder fixedly mounted on the top of the support frame, a pressure head fixedly mounted on the transmission end of the hydraulic cylinder extending downwards into the interior of the support frame, a pressure sensor fixedly mounted on the bottom of the pressure head, and the pressure sensor electrically connected to an external control panel via a flexible wire, a support base fixedly mounted in the middle of the upper part of the workbench, a placement groove opened in the middle of the top of the support base, a servo motor fixedly mounted on one side inner wall of the workbench via a support plate, a limit groove opened at the bottom of the support base, and stops slidably mounted on both sides inside the limit groove, a transmission assembly provided at the output end of the servo motor, the transmission assembly being connected to the two stops in a transmission manner, and when the servo motor operates, power is output to the two stops through the transmission assembly, causing the two stops to move back and forth to open.

[0006] Preferably, the transmission assembly includes a lower sprocket, which is fixedly installed at the output end of the servo motor. A positioning seat is rotatably installed on one side of the lower sprocket, and one end of the positioning seat is fixedly connected to the inner wall of one side of the worktable. An upper sprocket is provided above the lower sprocket, and a chain is meshed between the lower sprocket and the upper sprocket. A shaft is fixedly installed in the middle of the upper sprocket, and the surface of the shaft is rotatably connected to the inner top of the worktable through two bushings.

[0007] Preferably, both ends of the shaft are fixedly mounted with driving bevel gears, one side of the surface of the driving bevel gears is meshed with a driven bevel gear, and one side of the driven bevel gears is fixedly mounted with a rotating shaft. The surfaces of the two rotating shafts are rotatably connected to the inner wall of one side of the worktable through a shaft seat.

[0008] Preferably, one end of each rotating shaft is fixedly mounted with a toothed column, one end of each toothed column is rotatably mounted with a positioning frame, the ends of the two positioning frames that are far apart from each other are fixedly connected to the inside of the worktable, and the top of each toothed column is meshed with a rack, the upper side of the two racks is fixedly connected to the bottom of the two stops respectively.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator places the welded joint inside the placement groove in the support base, and then starts the hydraulic cylinder to drive the pressure head to move down into the placement groove, thereby performing compression testing on the welded joint. The pressure sensor will transmit the compression data to the control panel for display. After the test is completed, the operator starts the servo motor to drive the lower sprocket to rotate. The lower sprocket drives the upper sprocket to rotate through the chain. When the upper sprocket rotates, it drives the two active bevel gears to rotate through the shaft.

[0010] When the two driving bevel gears rotate, they drive the two driven bevel gears to rotate the two shafts. When the two shafts rotate, they drive the two racks to move towards each other through the toothed column. When the two racks move towards each other, they drive the two stops to slide back and forth inside the limiting slide groove, so that the welded joint that has been tested falls into the collection bucket for unloading and collection. This allows the welded joint compression testing device to quickly and conveniently complete the unloading and collection after the test, reducing the amount of manual labor and ensuring the continuity of processing.
