Description

Technical Field

[0001] This utility model relates to the field of spring tension and compression testing machine fixture technology, and in particular to a spring tension and compression testing machine fixture structure that facilitates fixture replacement. Background Technology

[0002] Springs are an important component in industrial systems and are used in large quantities and come in many varieties. During the manufacturing process of springs, performance tests are required to check whether the springs meet the requirements. Spring tension and compression testing machines are specialized instruments for testing the deformation and load relationship characteristics of tension and compression springs.

[0003] As shown in the reference case "A Spring Tension and Compression Testing Machine" (Announcement No. CN219798678U), the clamping mechanism uses a rotating ring to drive the screw to rotate, bringing hook one and hook two closer together. Then, the two ends of the spring are fixed to the upper hook and the lower hook respectively, clamping and fixing the spring. This allows the spring to act on the plumb line of the upper and lower connecting rings, preventing rotation when the spring tension and compression testing machine applies tension to the spring and improving the accuracy of the test.

[0004] When testing springs of different sizes, spring tension and compression testing machines usually require changing different clamps. However, if the clamps are not securely fixed during the change, they may become loose, causing deviations during the spring test and affecting the accuracy of the test data.

[0005] Therefore, a spring tension and compression testing machine fixture structure that facilitates fixture replacement is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a spring tension and compression testing machine fixture structure that facilitates fixture replacement in order to solve the above-mentioned problems. This improves the problem that when testing springs of different sizes, different fixtures usually need to be replaced. However, if the fixtures are not stably fixed during replacement, the fixtures will become loose, causing deviations during the spring testing process and affecting the accuracy of the test data.

[0007] This utility model achieves the above-mentioned objectives through the following technical solution: a spring tension and compression testing machine fixture structure that facilitates fixture replacement, comprising: a spring testing machine and a testing platform, wherein the testing platform is fixedly installed inside the spring testing machine, and multiple fixtures are arranged inside the spring testing machine; a replacement detection mechanism, which is used to facilitate fixture replacement and to detect the installation stability of the fixtures after installation, is arranged on the outside of the fixtures; wherein, the replacement detection mechanism includes a mounting frame arranged on the outside of the fixtures, a detection component for detecting installation stability is arranged between the mounting frame and the fixtures, and a disassembly component is arranged on the outside of the mounting frame; the multiple fixtures are respectively arranged on one side of the testing platform and the spring testing machine; during use, the fixtures can be easily and quickly installed and disassembled through the disassembly component, making fixture replacement very convenient; and during each installation and use of the fixtures, the stability between the fixtures and the mounting frame can be monitored in real time through the detection component, ensuring that the fixtures do not loosen or misalign during use, and avoiding test deviations or errors caused by fixture instability.

[0008] Preferably, the detection component includes a movable groove inside the fixture, with both ends of the movable groove penetrating the fixture. Limiting blocks are provided on both sides of the movable groove, and limiting openings are provided on both sides of the mounting frame. The two limiting blocks are slidably connected to the two limiting openings respectively. A pressure sensor is fixedly installed on the inner bottom wall of the mounting frame, and a controller is fixedly installed on the outer side of the mounting frame. The output end of the pressure sensor is in contact with one side of the fixture. When installing the fixture, the fixture can be slidably connected to the mounting frame. When the two limiting blocks move to the corresponding limiting openings, the limiting blocks and limiting openings slide and engage, completing the installation of the fixture. When the fixture moves downward, the pressure sensor senses the downward pressure of the fixture and automatically provides feedback on the stability of the fixture, effectively avoiding test failures caused by improper fixture installation.

[0009] Preferably, the detection component further includes two first springs fixedly installed inside the movable groove. The other ends of the two first springs are respectively fixedly connected to two limiting blocks. Both limiting blocks are slidably connected to the movable groove. When the two limiting blocks move to the corresponding limiting opening, the two first springs inside the movable groove will push the limiting blocks to move stably into the corresponding limiting opening for sliding engagement, thereby improving installation stability.

[0010] Preferably, two warning lights are fixedly installed on the outside of the mounting frame. Multiple mounting frames are respectively fixedly connected to the corresponding test bench and spring testing machine. The warning lights can provide real-time feedback during the fixture installation process. If the pressure value decreases, the warning light will immediately issue a warning to remind the operator that the fixture may not be installed correctly or may be loose, so as to detect potential problems in time.

[0011] Preferably, the two limiting blocks are both set to a semi-circular shape on the side that is far apart from each other, and the semi-circular side of the limiting block extends into the interior of the corresponding limiting opening, so that when the limiting block approaches the limiting opening, the limiting block can slide more smoothly into the interior of the corresponding limiting opening.

[0012] Preferably, the disassembly and assembly assembly includes two guide rods fixedly installed on the outside of the mounting frame. A drive block is slidably installed on the outside of each of the two guide rods. A push block is fixedly installed on the adjacent side of each of the two drive blocks, and the two push blocks are respectively aligned with two limit ports. When it is necessary to disassemble and replace the fixture, the two drive blocks can be brought close together, and the two push blocks can be inserted into the limit ports to move the limit blocks out, which makes it very convenient to disassemble the fixture.

[0013] Preferably, the disassembly and assembly assembly further includes a second spring that passes through and is sleeved on the outside of the two guide rods. The two second springs are respectively fixedly connected to the two drive blocks. When the two drive blocks are moved, the corresponding second springs deform synchronously. After the drive blocks are released after use, the second springs reset and can synchronously drive the drive blocks to reset.

[0014] The beneficial effects of this utility model are:

[0015] 1. The fixture can be easily and quickly installed and disassembled by the disassembly and assembly components, making it very convenient to replace the fixture. In addition, the stability between the fixture and the mounting frame can be monitored in real time by the detection component each time the fixture is installed and used, ensuring that the fixture does not become loose or misaligned during use, and avoiding test deviations or errors caused by fixture instability.

[0016] 2. When it is necessary to disassemble and replace the fixture, the two drive blocks can be brought close together, and the two push blocks can be put into the limit port to move the limit block out, which makes it very convenient to disassemble the fixture. When the two drive blocks are moved, the corresponding second spring deforms synchronously. After the drive blocks are released after use, the second spring resets and drives the drive blocks to reset synchronously. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In practical implementation: such as Figure 1-4 As shown, a spring tension and compression testing machine fixture structure with easy fixture replacement includes: a spring testing machine 1 and a testing table 2. The testing table 2 is fixedly installed inside the spring testing machine 1, and multiple fixtures 21 are arranged inside the spring testing machine 1. A replacement detection mechanism 3 is arranged on the outside of the fixtures 21 to facilitate the replacement of the fixtures 21 and to detect the installation stability of the fixtures 21 after installation. The replacement detection mechanism 3 includes a mounting frame 31 arranged on the outside of the fixtures 21, and a detection mechanism for detecting installation stability is arranged between the mounting frame 31 and the fixtures 21. The testing component 32 and the mounting frame 31 are provided with a disassembly and assembly component 33 on the outside. Multiple clamps 21 are respectively set on one side of the test bench 2 and the spring testing machine 1. During use, the clamps 21 can be installed and disassembled conveniently and quickly through the disassembly and assembly component 33, making it very convenient to replace the clamps 21. Moreover, the stability between the clamps 21 and the mounting frame 31 can be monitored in real time through the testing component 32 each time the clamps 21 are installed and used, ensuring that the clamps 21 do not become loose or misaligned during use, and avoiding test deviations or errors caused by the instability of the clamps 21.

[0024] The spring testing machine 1 can control the test bench 2 to move up and down to perform tensile and compressive tests on the spring. Usually, the clamp 21 needs to be replaced in the tensile test. The detection component 32 is used to detect the installation stability of the clamp 21 after installation, and it will not affect the normal use of the spring testing machine 1. At the same time, the disassembly and assembly component 33 improves the disassembly and assembly of the clamp 21 and the mounting frame 31, so it does not affect the function and use of the clamp 21 itself.

[0025] like Figure 2 , Figure 3 and Figure 4As shown, the detection component 32 includes a movable groove 321 formed inside the fixture 21, with both ends of the movable groove 321 penetrating the fixture 21. Limiting blocks 322 are provided on both sides of the movable groove 321. Limiting openings 323 are formed on both sides of the mounting frame 31. The two limiting blocks 322 are slidably connected to the two limiting openings 323 respectively. A pressure sensor 324 is fixedly installed on the inner bottom wall of the mounting frame 31, and a controller 325 is fixedly installed on the outer side of the mounting frame 31. The output end of the pressure sensor 324 contacts one side of the fixture 21. When installing the fixture 21, it can be slidably connected to the mounting frame 31. When the two limiting blocks 322 are located at the corresponding limiting openings 323, the limiting blocks 322 and the limiting openings 323 slide and engage, completing the installation of the fixture 21. Furthermore, when the clamp 21 moves downward, the pressure sensor 324 senses the downward pressure of the clamp 21. After the clamp 21 is installed in place, it can sense the change in the downward pressure of the clamp 21 in real time and automatically provide feedback on the stability of the clamp 21, effectively avoiding test failure due to improper installation of the clamp 21. The detection component 32 also includes two first springs 327 fixedly installed inside the movable groove 321. The other ends of the two first springs 327 are respectively fixedly connected to two limit blocks 322. Both limit blocks 322 are slidably connected to the movable groove 321. When the two limit blocks 322 move to the corresponding limit opening 323, the two first springs 327 inside the movable groove 321 will push the limit blocks 322 to move stably into the corresponding limit opening 323 for sliding engagement, thereby improving installation stability.

[0026] Two warning lights 326 are fixedly installed on the outside of the mounting frame 31. Multiple mounting frames 31 are fixedly connected to the corresponding test bench 2 and spring testing machine 1 respectively. The warning lights 326 can provide real-time feedback during the installation of the fixture 21. When the fixture 21 is installed stably and sufficient pressure is applied, the pressure value sensed by the pressure sensor 324 will be maintained within the standard range to ensure that the fixture 21 is installed stably. If the pressure value drops, the warning light 326 will immediately issue a warning to remind the operator that the fixture 21 may not be installed correctly or may be loose, so as to discover potential problems in time. The two limiting blocks 322 are both set to a semi-circular shape on the side that is far apart from each other, and the semi-circular side of the limiting block 322 extends into the interior of the corresponding limiting port 323. When the limiting block 322 approaches the limiting port 323, the limiting block 322 can slide more smoothly into the interior of the corresponding limiting port 323.

[0027] like Figure 2 , Figure 3 and Figure 4As shown, the disassembly and assembly component 33 includes two guide rods 331 fixedly installed on the outside of the mounting frame 31. A drive block 332 is slidably installed on the outside of each of the two guide rods 331. A push block 333 is fixedly installed on the adjacent side of each of the two drive blocks 332, and the two push blocks 333 are respectively aligned with the two limit ports 323. When it is necessary to disassemble and replace the clamp 21, the two drive blocks 332 can be brought close together, and the two push blocks 333 can be inserted into the limit ports 323 to move the limit blocks 322 out, so that the clamp 21 can be disassembled very conveniently. The disassembly and assembly component 33 also includes a second spring 334 that is sleeved through the outside of the two guide rods 331. The two second springs 334 are respectively fixedly connected to the two drive blocks 332. When the two drive blocks 332 are moved, the corresponding second springs 334 deform synchronously. After the drive blocks 332 are used and released, the second springs 334 reset, which can synchronously drive the drive blocks 332 to reset.

[0028] In use, when installing the clamp 21, the clamp 21 can be slidably connected to the mounting frame 31. When the two limiting blocks 322 are located at the corresponding limiting ports 323, the limiting blocks 322 and the limiting ports 323 slide and engage, completing the installation of the clamp 21. When the clamp 21 moves down, the pressure sensor 324 senses the downward pressure of the clamp 21. When the clamp 21 is installed stably and sufficient pressure is applied, the pressure value sensed by the pressure sensor 324 will remain within the standard range, ensuring that the clamp 21 is installed securely. If the pressure value decreases, the warning light 326 will immediately issue a warning, reminding the operator that the clamp 21 may not be installed correctly or may be loose, thus promptly identifying potential problems. When it is necessary to disassemble and replace the clamp 21, the two driving blocks 332 can be brought close together, and the two pushing blocks 333 can be inserted into the limiting ports 323 to move the limiting blocks 322 out, making the disassembly of the clamp 21 very convenient.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
