Description

Technical Field

[0001] This utility model belongs to the field of seamless internal thread copper tube testing technology, specifically a tensile strength testing device. Background Technology

[0002] Seamless internally threaded copper tubes are copper tubes with a smooth outer surface and continuous helical teeth on the inner surface. They represent the advanced level of current refrigeration heat exchange tubing. Through precise physical structure design, they achieve a leap in heat exchange performance without significantly increasing material costs. They are an indispensable key component in modern high-efficiency energy-saving refrigeration and air conditioning systems, mainly used in heat exchangers (such as evaporators and condensers) of air conditioning and refrigeration systems to enhance boiling or condensation heat transfer. Before use, seamless internally threaded copper tubes require tensile strength testing to ensure their quality. Existing tensile strength testing equipment typically uses clamps fixed to the top of the workbench by welding or bolting, making it difficult to easily change the clamps according to different copper tube specifications. This also leads to slippage of the copper tube during tensile testing, affecting the test results. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a tensile strength testing device, which solves the problem that when using tensile strength testing devices, the clamps are generally fixed to the top of the worktable by welding or bolting, making it difficult to arbitrarily change the corresponding clamps according to different copper tube specifications, and the copper tube is prone to slippage during tensile testing, affecting the testing effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tensile strength testing device, comprising a workbench, a tensile detector fixedly connected to one side of the top of the workbench, a testing seat installed on one side of the tensile detector, a movable groove opened on the top of the workbench, a movable block slidably connected inside the movable groove, a movable seat fixedly connected to the top of the movable block, mounting frames fixedly connected to one side of the top of the movable seat and the testing seat respectively, a rotating rod rotatably connected inside the mounting frame via a pin, a limiting seat fixedly connected to the top of the movable seat and the testing seat away from the mounting frame respectively, a pin slidably connected through the top of the limiting seat, the pin being inserted and fixedly connected to the rotating rod, and a fixed frame inserted into the opposite side of the movable seat and the testing seat respectively, with the rotating rod resting on one side of the top of the fixed frame.

[0005] As a further embodiment of this utility model: a fixing clip is fixedly connected between the bottom of the inner wall of the fixing frame, two limiting blocks are fixedly connected to one side of the fixing clip, and a support frame is fixedly connected to the top of the fixing frame.

[0006] As a further embodiment of this utility model: an electric push rod is fixedly connected to the top of the support frame, and a movable clamp is installed through the bottom of the electric push rod through the support frame. The movable clamp and the fixed clamp are positioned opposite each other, and anti-slip pads are fixedly connected to the opposite sides of the movable clamp and the fixed clamp, respectively.

[0007] As a further embodiment of this utility model: two fixing blocks are fixedly connected to one side of the movable clamp, the fixing blocks and the limiting blocks are positioned correspondingly, and the top of the movable clamp is fixedly connected to the two sides of the electric push rod, the limiting rods and the support frame are slidably connected through each other.

[0008] As a further embodiment of this utility model: two connecting blocks are fixedly connected to the bottom of the detection seat, and two limiting grooves are opened on the bottom of the worktable located at the bottom of the detection seat, with the inner wall of the limiting grooves slidably connected to the connecting blocks.

[0009] As a further embodiment of this utility model: a motor is fixedly connected to one side of the workbench, and the motor extends through an output shaft to the inside of the movable slot where a threaded rod is installed. The threaded rod is rotatably connected to the inner wall of the movable slot through a bearing, and the threaded rod is threadedly connected to the movable block.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This tensile strength testing device, by setting a fixed frame, a rotating rod, and a pin, moves the pin upward, thus removing the pin from the rotating rod and eliminating the limiting effect on the rotating rod. Rotating the rotating rod moves it away from the top of the fixed frame, aligning the appropriate fixed frame with the top of the testing seat or movable seat, causing the fixed frame to move downward and insert into the testing seat or movable seat. Rotating the rotating rod again causes it to abut against the top of the fixed frame, allowing the pin to be inserted and fixed. This enables the replacement of the fixed clamp and movable clamp inside the testing seat or movable seat, making the fixed clamp and movable clamp adaptable to the shape of the copper tube, allowing the fixed clamp and movable clamp to limit and clamp the copper tube, thus improving the practicality of the equipment. 2. This tensile strength testing equipment, by setting up an electric push rod, a fixed clamp, a movable clamp, and an anti-slip pad, when the copper tube is placed on the anti-slip pad on top of the fixed clamp, the electric push rod drives the movable clamp to move downward, causing the movable clamp to move the anti-slip pad towards the surface of the copper tube, so that the anti-slip pad presses against the surface of the copper tube, and the movable clamp, together with the fixed clamp, stably clamps the copper tube, thereby clamping the copper tube between the testing seat and the movable seat, which facilitates the tensile testing of the copper tube.

Detailed Implementation

[0012] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0013] like Figure 1-3 As shown, this utility model provides a technical solution: a tensile strength testing device, including a workbench 1, a motor 21 fixedly connected to one side of the workbench 1, the motor 21 extending through an output shaft to the interior of a movable groove 4 where a threaded rod 22 is installed, the threaded rod 22 being rotatably connected to the inner wall of the movable groove 4 through a bearing, and the threaded rod 22 being threadedly connected to a movable block 5. By setting the motor 21, the motor 21 drives the threaded rod 22 to rotate through the output shaft, causing the threaded rod 22 to move the movable block 5, thereby causing the movable block 5 to move the movable seat 6, so that the movable seat 6 can pull the copper tube for strength testing; A tensile detector 2 is fixedly connected to one side of the top of the workbench 1. A detection seat 3 is installed on one side of the tensile detector 2. Two connecting blocks 19 are fixedly connected to the bottom of the detection seat 3. Two limiting grooves 20 are opened at the bottom of the workbench 1 and the inner wall of the limiting groove 20 is slidably connected to the connecting block 19. By setting the limiting groove 20, the detection seat 3 drives the connecting block 19 to slide inside the limiting groove 20, so that the limiting groove 20 can limit the movement of the detection seat 3 through the connecting block 19, making the movement of the detection seat 3 more stable. The top of the workbench 1 is provided with a movable groove 4, and a movable block 5 is slidably connected inside the movable groove 4. A movable seat 6 is fixedly connected to the top of the movable block 5. A mounting frame 7 is fixedly connected to the top side of the movable seat 6 and the top side of the detection seat 3 respectively. A rotating rod 8 is rotatably connected inside the mounting frame 7 through a pin. By setting the rotating rod 8, the rotating rod 8 can rotate to the top of the fixed frame 11, thereby limiting the fixed frame 11, so that the fixed frame 11 can be fixed inside the detection seat 3 or the movable seat 6. The top of the movable seat 6 and the detection seat 3, away from the mounting frame 7, are respectively fixedly connected to the limiting seat 9. The top of the limiting seat 9 is slidably connected with the pin 10, which is inserted and fixedly connected to the rotating rod 8. The movable seat 6 and the detection seat 3 are respectively inserted with the fixed frame 11 on opposite sides, and the rotating rod 8 rests on one side of the top of the fixed frame 11. By setting the fixed frame 11, the fixed frame 11 can drive the fixed clamp 12 and the movable clamp 15 to move, so that the fixed clamp 12 and the movable clamp 15 can be fixedly installed on the detection seat 3 or the movable seat 6, so that the fixed clamp 12 and the movable clamp 15 can be replaced. A fixing clip 12 is fixedly connected between the bottom of the inner wall of the fixing frame 11. Two limiting blocks 17 are fixedly connected to one side of the fixing clip 12. A support frame 13 is fixedly connected to the top of the fixing frame 11. By setting the limiting blocks 17, when the movable clip 15 moves, it drives the fixing block 16 to move inside the limiting block 17, so that the limiting block 17 can limit the movement of the movable clip 15 through the fixing block 16, ensuring that the movable clip 15 will not be misaligned or offset when it moves at the top of the fixing clip 12. An electric push rod 14 is fixedly connected to the top of the support frame 13. A movable clamp 15 is installed at the bottom of the electric push rod 14 through the support frame 13. The movable clamp 15 is positioned opposite to the fixed clamp 12. Anti-slip pads 23 are fixedly connected to the opposite sides of the movable clamp 15 and the fixed clamp 12. By setting the anti-slip pads 23, when the movable clamp 15 and the fixed clamp 12 clamp the copper tube, the anti-slip pads 23 can press against the surface of the copper tube. Thus, the anti-slip pads 23 increase the clamping effect on the copper tube through friction, so that the copper tube can be stably fixed between the movable clamp 15 and the fixed clamp 12. Two fixing blocks 16 are fixedly connected to one side of the movable clamp 15. The fixing blocks 16 are corresponding to the positions of the limiting blocks 17. Limiting rods 18 are fixedly connected to both sides of the electric push rod 14 at the top of the movable clamp 15. The limiting rods 18 are slidably connected to the support frame 13. By setting the limiting rods 18, the electric push rod 14 drives the movable clamp 15 to move. The movable clamp 15 can drive the limiting rods 18 to rotate together, so that the limiting rods 18 slide inside the support frame 13. Thus, the movement of the movable clamp 15 is limited by the limiting rods 18, making the movement of the movable clamp 15 more stable.

[0014] The working principle of this utility model is as follows: Align the fixed frame 11 corresponding to the copper tube with the top of the detection seat 3 and the movable seat 6, and move the fixed frame 11 down so that it is inserted into the detection seat 3 and the movable seat 6. Then rotate the rotating rod 8 so that it enters the limiting seat 9 and rests against the top of the fixed frame 11. Move the pin 10 down so that it engages with the rotating rod 8 to fix and limit the fixed frame 11. Fix the fixed frame 11 inside the detection seat 3 and the movable seat 6. Then place the copper tube on the anti-slip pad 23 on the top of the fixed clamp 12. Start the electric push rod 14. The electric push rod 14 drives the movable clamp 15 down so that the anti-slip pad 23 inside the movable clamp 15 rests against the surface of the copper tube to clamp and fix the copper tube. Start the motor 21. The motor 21 drives the threaded rod 22 to rotate through the output shaft. The threaded rod 22 drives the movable seat 6 to move through the movable block 5, so that the movable seat 6 cooperates with the detection seat 3 to stretch the copper tube, and the tensile tester 2 performs strength testing on the copper tube.
