Description

Technical Field

[0001] The utility model relates to the technical field of titanium tube production inspection, in particular to a titanium tube tensile testing device. Background Art

[0002] The main function of the titanium tube tensile test device is to evaluate the tensile properties and mechanical characteristics of titanium tube materials. Specifically, this device can be used in the following aspects: material research and development, quality control and quality inspection, engineering design and safety assessment. In summary, the titanium tube tensile test device plays an important role in material research, quality control, engineering design and safety assessment, and can provide reliable data support for the development, production and application of titanium tube materials.

[0003] There are many existing technologies for tensile testing devices, such as:

[0004] Chinese patent publication number CN220170838U discloses a tensile performance testing device, which includes a workbench, a fixed bracket is installed on the top of the workbench, a guide rail is installed on the top of both sides of the fixed bracket, a connecting plate is installed on both sides of the workbench, a U-shaped fixed groove is installed on both sides of the fixed bracket, the bottom of the U-shaped fixed groove is installed on the top of the connecting plate, a transparent baffle is movably installed on the inner side of the U-shaped fixed groove, a U-shaped fixed groove is installed on the front of the fixed bracket, and a transparent baffle is movably installed on the inner side of the U-shaped fixed groove. The utility model is installed with transparent baffles 1 and 2, and transparent baffles 1 are installed on both sides of the bracket from the front through fixed grooves 1, fixed grooves 2 are installed on the front of the workbench and the front of the bracket, and transparent baffles 2 are inserted and installed from the top to block splashing objects, avoid accidental injuries by splashing debris, and protect testers from being scratched.

[0005] The existing titanium tube tensile test device usually fixes the titanium tube by a clamping mechanism first, and then performs a performance test on the titanium tube by the tensile test mechanism, which is difficult to meet the test requirements for titanium tubes of different lengths. In addition, if different parts of the titanium tube need to be tensile tested, the operator needs to remove the titanium tube from the clamping mechanism, change the position of the titanium tube, and then re-fix the titanium tube on the clamping mechanism, which is time-consuming and affects the efficiency of the test. For example, a tensile performance test device proposed in the above patent places the workpiece to be tested on a fixed bracket, and then performs a tensile test on the workpiece, but it meets the above-mentioned requirements of testing titanium tubes of different lengths and continuously and quickly testing different parts of the titanium tube.

[0006] In view of this, we propose a titanium tube tensile testing device, which fixes the titanium tube by a pair of clamping assemblies, and adjusts the positions of the two clamping assemblies by adjusting the assembly to meet the testing needs of titanium tubes of different lengths. When different parts of the titanium tube need to be tested, the turntables at both ends of the adjusting assembly are rotated towards each other, so that the two clamping assemblies can drive the titanium tube to move forward and backward synchronously, thereby realizing the testing of different parts of the titanium tube.

[0028] Working principle: When the titanium tube tensile testing device provided by the utility model is used, the titanium tube is fixed by a pair of clamping assemblies 20, and the positions of the two clamping assemblies 20 are adjusted by the adjusting assembly 10 to meet the testing requirements of titanium tubes of different lengths. When different parts of the titanium tube need to be tested, the turntables at both ends of the adjusting assembly 10 are rotated in opposite directions, so that the two clamping assemblies 20 drive the titanium tube to move forward and backward synchronously, thereby realizing the testing of different parts of the titanium tube. The driving assembly 30 is used to drive the testing assembly 40 to continuously test the titanium tube fixed between the two clamping assemblies 20.

[0029] In order to adjust the positions of the two clamping assemblies 20, the adjusting assembly 10 includes a limit bolt 11, and threaded rods 12 are rotatably connected on both sides of the limit bolt 11. The tops of the two threaded rods 12 are threadedly connected to fixed seats 13, and the end of the threaded rod 12 away from the limit bolt 11 is coaxially connected to a turntable; rotating the turntable drives the threaded rod 12 coaxially connected thereto to rotate, and the threaded rod 12 then drives the fixed seat 13 threadedly connected thereto to move forward and backward, thereby driving the clamping assembly 20 to move forward and backward on the threaded rod 12.

[0030] Taking into account the need to fix the titanium tube to meet the testing requirements of titanium tubes of different lengths, the clamping assembly 20 includes a main rod 21 installed on the top of the fixed seat 13, and a driving ring 22 is slidably connected to the main rod 21. Hydraulic rods 23 are provided on both sides of the main rod 21, and the piston ends of the two hydraulic rods 23 are fixedly connected to the driving ring 22. The end of the main rod 21 away from the fixed seat 13 is rotatably connected to a pair of symmetrically arranged clamping arms 24, and the backs of the two clamping arms 24 are rotatably connected to a linkage rod 25, and the end of the linkage rod 25 away from the clamping arm 24 is rotatably connected to the driving ring 22; start the hydraulic rod 23, and push the driving ring 22 to slide on the main rod 21 through its piston end, and driven by the linkage rod 25, drive the two clamping arms 24 to open and close, thereby clamping the titanium tube.

[0031] In order to continuously test the titanium tube fixed between the two clamping assemblies 20, the driving assembly 30 includes a reciprocating ring 31, a single-sided gear 32 is meshed in the reciprocating ring 31, and a top shaft 33 is fixedly connected to the outer wall of the reciprocating ring 31 in the direction of movement of the reciprocating ring 31.

A slide rod 43 is connected, and a test arm 44 is fixedly connected to the top of the slide rod 43; an elastic member is provided between the test arm 44 and the base. After the power is turned on, the motor drives the single-sided gear 32 coaxially connected to its output shaft to rotate, and the single-sided gear 32 drives the reciprocating ring 31 to reciprocate left and right, thereby continuously driving the pedestal seat 41 to reciprocate left and right through the top shaft 33. Under the drive of the pedestal seat 41 and the restoring force of the elastic member, the test arm 44 continuously reciprocates up and down, thereby continuously testing the titanium tube.

[0032] When the titanium tube tensile testing device provided in the utility model is used, the titanium tube is fixed by a pair of clamping assemblies 20. Specifically, the hydraulic rod 23 is started, and the driving ring 22 is pushed to slide on the main rod 21 through its piston end. Under the drive of the linkage rod 25, the two clamping arms 24 are driven to open and close, so as to clamp the titanium tube; the positions of the two clamping assemblies 20 are adjusted by the adjustment assembly 10, so as to meet the testing requirements of titanium tubes of different lengths. Specifically, the turntable is rotated to drive the threaded rod 12 coaxially connected thereto to rotate, and the threaded rod 12 then drives the fixing seat 13 threadedly connected thereto to move forward and backward, thereby driving the clamping assembly 20 to move forward and backward on the threaded rod 12; when different parts of the titanium tube need to be tested, the two clamping arms 24 are rotated in opposite directions. The turntables at both ends of the adjustment component 10 enable the two clamping components 20 to drive the titanium tube to move forward and backward synchronously, thereby realizing the testing of different parts of the titanium tube. The driving component 30 is used to drive the test component 40 to continuously test the titanium tube fixed between the two clamping components 20. Specifically, an elastic member is provided between the test arm 44 and the base. After the power is turned on, the motor drives the single-sided gear 32 coaxially connected to its output shaft to rotate, and the single-sided gear 32 drives the reciprocating ring 31 to reciprocate left and right, thereby continuously driving the pedestal seat 41 to reciprocate left and right through the top shaft 33.
