Description

Technical Field

[0001] The utility model relates to the technical field of wire resin strength detection, in particular to a fixture for bond strength detection. Background Art

[0002] A high-pressure resin pipe refers to a high-pressure hose formed by using a plastic material extruded into a hose as the inner core and reinforced by braiding or winding with high-strength industrial fibers or wires. The pipe body generally has a three-layer structure: an inner hose layer, a skeleton reinforcement layer, and an outer rubber layer. The high-pressure resin pipe braided with fibers (wires) has the characteristics of light pipe body, high pressure resistance, small bearing deformation, good resistance to media, aging resistance, and convenient use. The quality of the high-pressure resin pipe partly depends on the bond strength between the wire and the resin, and it is necessary to detect the bond strength between the wire and the resin to judge the connection quality between the wire and the resin.

[0003] When detecting the bond strength of a high-pressure resin pipe, it is necessary to pre-prepare a model to be detected. The model to be detected includes two modules and a wire connecting the two modules. It is necessary to use a tensile strength tester to stretch the two modules until the wire moves relative to the module to obtain corresponding data.

[0032] The preferred embodiments of the present utility model will be specifically described below with reference to the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present utility model to explain the principle of the present utility model, rather than to limit the scope of the present utility model.

[0033] A fixture for bonding degree detection in this embodiment relates to the technical field of steel wire resin strength detection. It is provided with two clamping blocks 110 that can clamp the model 300 to be detected. With the help of a tensile strength tester, the two clamping blocks 110 can be driven to move away from each other to detect the bonding degree. A limiting groove body 210 is sleeved outside the clamping block 110, and the limiting groove body 210 is connected with the clamping block 110 in a matching manner, which can simplify the installation arrangement between the two clamping blocks 110, ensure the integrity of the model 300 to be detected, and improve the clamping efficiency.

[0034] Please refer to Figures 1 to 7 , a fixture for bonding degree detection in this embodiment includes a clamping assembly 100 and a limiting assembly 200. The clamping assembly 100 can clamp the model 300 to be detected to assist the subsequent bonding degree detection. The limiting assembly 200 can position and fix the clamping assembly 100 to assist the cooperation between the clamping assembly 100 itself and between the clamping assembly 100 and the model 300 to be detected.

[0035] The clamping assembly 100 includes two clamping blocks 110 arranged at intervals relatively. One end of the clamping block 110 is provided with a clamping groove 111. The clamping groove 111 can hold a module 310 of the model 300 to be detected. The other end of the clamping block 110 is used to be connected with a tensile strength tester. The two modules 310 of the model 300 to be detected are respectively clamped by the two clamping blocks 110. The tensile strength tester acts on the two clamping blocks 110 respectively to pull the module 310, so as to realize the detection of the bonding degree between the steel wire 320 and the module 310.

[0036] The limiting component 200 includes a limiting groove body 210 and a clamping unit 220. The limiting groove body 210 is sleeved on the two clamping blocks 110, and the limiting groove body 210 is slidably connected to the clamping blocks 110. The limiting groove body 210 can limit the positions of the two clamping blocks 110 and assist the two clamping blocks 110 to cooperate. The clamping unit 220 includes a clamping groove 221 formed on the clamping block 110 and a limiting member 222. The limiting member 222 passes through the limiting groove body 210 and is inserted into the clamping groove 221. The limiting member 222 and the clamping groove 221 cooperate to limit the position of the clamping block 110, so that both clamping blocks are constrained in the limiting groove body 210, preventing the clamping blocks from disengaging from the limiting groove body 210. The clamping groove 221 can limit the movement of the clamping block 110 in the extending direction of the limiting groove body 210, so that the two clamping blocks 110 can move along the extending direction of the limiting groove body 210 under the action of the tensile strength tester, realizing the detection of the bonding degree.

[0037] In some embodiments, please refer to Figures 1 to 3 , the clamping groove 221 includes a first extension section 221a arranged along the extending direction of the limiting groove body 210. The limiting member 222 is adapted to the first extension section 221a. The limiting groove body 210, the limiting member 222 and the first extension section 221a are mutually configured to fix the clamping block 110 in the limiting groove body 210, so that the clamping block 110 can only move along the first extension section 221a, and the bonding degree is detected under the action of the tensile strength tester, avoiding the displacement problem that the clamping block 110 may occur during the test, thereby reducing the test error. The limiting member 222 can prevent the clamping block 110 from moving relative to the opening direction of the limiting groove body 210, avoiding the clamping block 110 from disengaging from the side of the limiting groove body 210.

[0038] As a further implementation manner, please continue to refer to Figures 1 to 3 , the clamping groove 221 further includes a second extension section 221b arranged along the opening direction of the limiting groove body 210. The second extension section 221b is perpendicular to the first extension section 221a and intersects with the first extension section 221a. The second extension section 221b and the first extension section 221a are combined to form an "L"-shaped clamping groove 221. Under the action of the limiting member 222 adapted to the second extension section 221b, the clamping block 110 can only move relative to the extending direction of the limiting groove body 210. The second extension section 221b can limit the clamping block 110, so that the distance between the two clamping blocks 110 along the direction of the first extension section 221a remains unchanged, which can facilitate the installation of the model 300 to be detected and simplify the matching process of the module 310 and the steel wire 320 with the clamping groove 111.

[0039] In the specific implementation process, the limiting member 222 can be switched between the first extension section 221a and the second extension section 221b that are interconnected, making the installation process of the model 300 to be detected and the detection process of the bonding degree relatively independent. In different operation stages, the switching of the limiting member 222 enables the fixture to better adapt to different operation requirements and scenarios. At the same time, the mutual interference between the two processes is reduced, which helps to ensure that the operation of each process can be more focused and precise.

[0040] In some embodiments, please refer to Figure 3 , one end of the second extension section 221b away from the first extension section 221a is arranged opposite to the opening of the limiting groove body 210, and one end of the clamping block 110 away from the opening of the limiting groove body 210 can abut against the inner wall of the limiting groove body 210, providing additional support, which can ensure that the clamping block 110 will not be displaced or shaken due to uneven force during the operation process, and enhances the overall stability of the fixture.

[0041] At the same time, the close contact between the clamping block 110 and the inner wall of the limiting groove body 210 reduces the possible gaps or movements during the clamping and testing processes, thereby improving the accuracy of the fixture and helping to ensure the accuracy of the test results.

[0042] It should be particularly noted that, please refer to Figure 4 and Figure 5 , the limiting groove body 210 has a first state and a second state relative to the clamping block 110. In the first state, it is the detection process of the bonding degree, and in the second state, it is the installation process of the model 300 to be detected. In the first state, the limiting member 222 on the limiting groove body 210 is inserted into the first extension section 221a. Under the action of the tensile strength tester, the two clamping blocks 110 can move relatively away along the first extension section 221a, so as to test the bonding degree between the steel wire 320 and the module 310. In the second state, the limiting member 222 on the limiting groove body 210 is inserted into the second extension section 221b, and one side of the clamping block 110 away from the opening of the limiting groove body 210 abuts against the inner wall of the limiting groove body 210, providing additional support for the clamping block 110, so that the clamping block 110 can be stably placed and stored.

[0043] In the specific implementation process, first, place the two clamping blocks 110 with the end relative to the second extension section 221b facing down on the table, and insert the two modules 310 into the clamping grooves 111 respectively. Then, move the limiting groove body 210 and insert it into the two clamping blocks 110 from the opening, and insert the limiting member 222 so that the limiting member 222 is adapted to the second extension section 221b. Finally, flip the limiting groove body 210 so that the end of the limiting groove body 210 away from the opening faces down, and the side of the clamping block 110 away from the opening of the limiting groove body 210 abuts against the inner wall of the limiting groove body 210. The clamping block 110 is stably supported and cannot move along the extending direction of the limiting groove body 210 due to the obstruction of the second extension section 221b. The steel wire 320 is not affected by force, which can ensure that the bonding degree between the steel wire 320 and the module 310 is not interfered by the outside world and always remains constant. Just move the limiting groove body 210 along the second extension section 221b until the limiting member 222 contacts the first extension section 221a, and the detection process of the bonding degree can be carried out.

[0044] In some embodiments, please refer to Figure 6 , a connection hole 211 is provided on the limiting groove body 210, the middle part of the limiting member 222 is connected to the connection hole 211, and the bottom of the limiting member 222 is inserted into the card slot 221. The limiting member 222 is connected to the connection hole 211 through the middle part to ensure the stable fixation of the limiting member 222 during use. The bottom being inserted into the card slot 221 can further increase the fixing degree of the limiting member 222 and prevent the possible loosening or displacement of the limiting member 222 during the operation.

[0045] The connection design of the limiting member 222 and the connection hole 211 enables the limiting member 222 to be relatively easily replaced or adjusted, facilitating the disassembly and assembly of the clamping block 110 from the limiting groove body 210.

[0046] As a further implementation manner, the limiting member 222 is a pin or a bolt. When the limiting member 222 is a bolt, the connection hole 211 is a threaded hole, and the limiting member 222 is threadedly connected to the connection hole 211. The bolt has a stronger fixing force, and through the tightening of the thread, the limiting member 222 can be effectively fixed in the fixture. The bolt can provide an additional fixing force to ensure the reliability of the fixture during use.

[0047] When the limiting member 222 is a pin, the connection hole 211 is a through hole, and the pin is directly inserted into the through hole. The pin as the limiting member 222 can provide stable positioning and prevent the displacement or loosening of the limiting member 222 during the use of the fixture. The pin forms a firm fixation by inserting into the connection hole 211 and the card slot 221, increasing the stability of the fixture. The installation and disassembly of the pin are relatively simple, and the replacement or adjustment of the limiting member 222 can be carried out quickly without complex tools or steps.

[0048] In some embodiments, refer to Figure 3 The clamping groove 111 includes a first groove body 111a for clamping the module 310 and a second groove body 111b for installing the steel wire 320. The second groove body 111b is communicated with the first groove body 111a.

[0049] The first groove body 111a is specifically used for clamping the module 310 of the to-be-detected model 300, providing a stable fixing position, enabling the module 310 to remain stable during the test process and reducing the risk of displacement or loosening.

[0050] The second groove body 111b is used for installing the steel wire 320. It is communicated with the first groove body 111a, allowing the steel wire 320 to be easily installed in the fixture and remain in the correct position.

[0051] By arranging the first groove body 111a and the second groove body 111b in the same clamping groove 111, the fixture can simultaneously complete the functions of clamping the module 310 and installing the steel wire 320. This not only improves the applicable range of the fixture, enabling it to handle complex detection tasks, but also ensures the accurate relative position of the module 310 and the steel wire 320 in the fixture, reducing the test deviation caused by installation errors.

[0052] As a further implementation method, the cross-section of the first groove body 111a is the same as the shape and size of the cross-section of the module 310, and the depth of the first groove body 111a is greater than the thickness of the module 310. The cross-section shape and size of the first groove body 111a being the same as those of the module 310 ensure that the clamping groove 111 can completely match the shape of the to-be-detected module 310, guaranteeing the accuracy of clamping, enabling the module 310 to be firmly fixed in the clamping groove 111, and avoiding sliding or instability caused by shape mismatch.

[0053] The depth of the first groove body 111a being greater than the thickness of the module 310 enables the module 310 to be completely clamped in the groove body, providing an additional clamping surface for the module 310, increasing the clamping stability, and preventing the module 310 from displacing or loosening during the operation process.

[0054] In some embodiments, refer to Figure 3 The other end of the clamping block 110 is provided with a connecting portion 112. The connecting portion 112 is detachably connected to the tensile strength tester. The clamping block 110 assembled with the limiting groove body 210 can be connected to the tensile strength tester through the connecting portion 112. After the detection is completed, it can be quickly disassembled, optimizing the detection process and reducing the measurement difficulty. In the specific implementation process, the connecting portion 112 is provided with a pin hole 112a for connecting to the tensile strength tester. By using the pin connection method to connect the connecting portion 112 and the tensile strength tester, the rapid disassembly and assembly of the tensile strength tester and the clamping block 110 can be realized, improving the detection speed.

[0055] Workflow: First, place the two clamping blocks 110 with one end relative to the second extension section 221b facing down on the tabletop, and insert the two modules 310 into the clamping grooves 111 respectively. Then, move the limit groove body 210 and insert it into the two clamping blocks 110 from the opening, and insert the limiting member 222 so that the limiting member 222 is adapted to the second extension section 221b. Finally, turn over the limit groove body 210 so that the end of the limit groove body 210 far from the opening faces down, and the side of the clamping block 110 away from the opening of the limit groove body 210 abuts against the inner wall of the limit groove body 210. Next, connect the connecting parts 112 of the two clamping blocks 110 to the tensile strength tester respectively to make the connection between the clamping block 110 and the tester stable. Then, just move the limit groove body 210 along the second extension section 221b until the limiting member 222 contacts the first extension section 221a, then the tensile strength tester can be started to test the model 300 to be detected until the steel wire 320 disengages from the module 310. Finally, turn off the tester and disassemble the fixture and the model 300 to be detected.

[0056] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the present invention.
