Description

Technical Field

[0001] The embodiment of the present invention relates to the technical field of bending experiment, and in particular to a bending experiment testing device. Background Art

[0002] At present, after the compressor electric heating belt is produced, a flexure test is required to test the bending resistance of the sample. Existing flexure tests are mostly performed manually, which is not only labor-intensive and inefficient, but also inaccurate in test results and cannot guarantee the accuracy and precision of the flexure angle. Summary of the invention

[0003] The purpose of the embodiments of the present invention is to at least provide a bending experiment testing device, which can at least solve the problem of poor efficiency of manual inspection, at least improve test reliability, greatly reduce personnel costs, and have the effect of improving product inspection efficiency.

[0004] In order to solve the above technical problems, at least one embodiment of the present application provides a bending test device, comprising:

[0005] Base;

[0006] A rotating mechanism, the rotating mechanism comprising a rotating disc arranged on a base and a driving member for driving the rotating disc to rotate;

[0007] A linkage belt, the linkage belt is arranged around the outer surface of the rotating disk so as to follow the rotation of the rotating disk and move around the rotating disk;

[0008] and a clamping member provided on the linkage belt; the clamping member is used to fix the product to be tested on the linkage belt;

[0009] When the linkage belt moves around the rotating disk, the product to be tested undergoes bending deformation as the linkage belt moves.

[0010] The bending experiment test device provided in the embodiment of the present application is different from the prior art in that it uses a clamping member to fix the product to be tested on the linkage belt, thereby starting the driving member to drive the rotating disk to rotate, so that the rotating disk drives the linkage belt to move around the rotating disk, thereby causing the product to be tested to bend and deform as the linkage belt moves, thereby realizing automated bending testing and reducing personnel costs. It also uses mechanical transmission to drive the product to be tested to bend and deform, which is more conducive to performing bending experiments in multiple cycles, and each test process can be kept consistent, which not only speeds up the operation speed of the bending experiment, but also greatly shortens the experimental cycle, and significantly enhances the reliability and stability of the experimental results, thereby improving test reliability, greatly reducing personnel costs, and improving product detection efficiency.

[0011] In addition, the test device further comprises a counter, which is connected to the driving member and is used to record the number of rotation experiments of the rotating disk by monitoring the state of the driving member. By configuring the counter, the number of experiments can be automatically counted, thereby improving the reliability of the test.

[0012] In addition, the driving member is used to drive the rotating disc to rotate clockwise and counterclockwise alternately; the counter records the number of times the driving member drives the rotating disc to complete the alternating rotation as the number of rotation experiments of the rotating disc; wherein, the rotating disc completes one alternating rotation when the rotating disc rotates from one circle clockwise to one circle counterclockwise. By using a reversible driving member to drive the rotating disc to rotate clockwise and counterclockwise alternately, the accuracy of the flexural test of the product to be tested can be improved, thereby combining with the counter to accurately record the number of experiments and improve the reliability and stability of the experiment.

[0013] In addition, the driving member includes a driving motor for alternately driving the rotating disc to rotate clockwise and counterclockwise; and a relay connected to the driving motor, the relay is used to control the commutation output of the driving motor. By configuring the relay, the commutation of the driving motor can be automatically controlled in combination with the time required for the driving motor to rotate one circle in one direction, thereby improving the convenience and efficiency of the test.

[0014] In addition, the rotating disc includes two roller discs, which are arranged on the surface of the base at a preset interval; the linkage belt is an annular belt, which is integrally fitted on the outer circumferential surfaces of the two roller discs to move with the rotation of the roller discs. By configuring the two roller discs to cooperate with the annular linkage belt, it is convenient to arrange the two ends of the product to be tested on the opposite sides of the linkage belt, thereby improving the flexural test effect.

[0015] In addition, the clamping member includes a first clamp and a second clamp; the first clamp and the second clamp are arranged on the linkage belt and on both sides of the line connecting the center points of the two roller discs to fix the two ends of the product to be tested respectively. Through the cooperation of the first clamp and the second clamp, it is convenient to fix the two ends of the product to be tested, avoid falling off during the test process, and improve the stability of the test process.

[0016] In addition, the distance between the first fixture and the two roller discs, and the distance between the second fixture and the two roller discs are both greater than the outer circumference of the roller discs. After the two ends of the product to be tested are fixed by the first fixture and the second fixture respectively, considering that the roller discs reverse after rotating one circle, the first fixture and the second fixture will not collide with the roller discs during the test, thereby improving the stability of the test process.

[0017] In addition, the clamping member includes a connecting block fixed on the linkage belt and a bolt assembly arranged on the connecting block; the bolt assembly is used to fix the product to be tested on the connecting block.

[0018] In addition, the outer surface of the rotating disk is arrayed with active teeth; the surface of one side of the linkage belt attached to the rotating disk is arrayed with linkage teeth, and the linkage teeth are meshed with the active teeth. The meshing of the linkage teeth with the active teeth improves the stability of the linkage belt when attached to the rotating disk, thereby facilitating the synchronous rotation of the linkage belt, avoiding idling, and improving the stability of the test.

[0019] In addition, the test device further comprises a control switch; the control switch is connected to the driving member and is used to control the start and stop of the driving member. The control switch facilitates the operator to control the start and stop of the test device, thereby improving the convenience of use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it can be understood by those skilled in the art that in the embodiments of the present invention, many technical details are provided to enable readers to better understand the present invention. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present invention can be implemented.

[0026] In order to facilitate understanding of the embodiments of the present application, relevant contents about the winding experiment are first introduced here.

[0027] At present, after the compressor electric heating belt is produced, it is necessary to conduct a flexure test to test the bending resistance of the sample. During the flexure test, the electric heating belt needs to be bent back and forth multiple times, and then observe whether the electric heating belt after multiple bending has wrinkles, cracks, whitening and other undesirable phenomena. If so, the product is judged as a defective product.

[0028] Most existing flexure tests are performed manually, which is not only labor-intensive and inefficient, but also inaccurate in test results and unable to guarantee the accuracy and precision of the flexure angle.

[0029] Embodiment 1:

[0030] An embodiment of the present invention relates to a bending test device.

[0031] Compared with the prior art, the implementation mode of the present invention adopts a clamping part to fix the product to be tested on the linkage belt, thereby starting the driving part to drive the rotating disk to rotate, so that the rotating disk drives the linkage belt to move around the rotating disk, so that the product to be tested is bent and deformed as the linkage belt moves, thereby realizing automated bending test and reducing personnel costs. In addition, mechanical transmission is used to drive the product to be tested to be bent and deformed, which is more conducive to performing bending test tests in cycles, and each test process can be kept consistent, which not only speeds up the operation speed of the bending test, but also greatly shortens the experimental cycle, so that the reliability and stability of the experimental results are significantly enhanced, thereby improving the test reliability, greatly reducing personnel costs, and having the effect of improving product detection efficiency.

[0032] The implementation details of the testing device of this embodiment are described in detail below. The following content is only provided for easy understanding of the implementation details and is not necessary for implementing this solution.

[0033] The embodiment of the present invention provides a bending test device, such as Figure 1 and Figure 2 As shown, it includes: a base 1, a rotating mechanism 2, a linkage belt 3 and a clamping member 4; wherein the rotating mechanism 2 includes a rotating disk 21 arranged on the base 1 and a driving member 22 for driving the rotating disk 21 to rotate; the linkage belt 3 is fitted and wound around the outer circular surface of the rotating disk 21 to move around the rotating disk 21 following the rotation of the rotating disk 21; the clamping member 4 is installed on the linkage belt 3, and is used to fix the product to be tested on the linkage belt 3, so that when the linkage belt 3 moves around the rotating disk 21, the product to be tested undergoes bending deformation as the linkage belt 3 moves.

[0034] Furthermore, the test device also includes a counter 5, which is connected to the driving member 22 and is used to record the number of rotation experiments of the rotating disk 21 by monitoring the state of the driving member 22. In this embodiment, after the driving member 22 drives the rotating disk 21 to rotate forward for one circle, it is reversed for one circle, which is recorded as a bending deformation experiment of the product to be tested. Based on this, the driving member 22 can drive the rotating disk 21 to rotate clockwise and counterclockwise alternately; the counter 5 records the number of times the driving member 22 drives the rotating disk 21 to complete alternating rotations as the number of rotation experiments of the rotating disk 21; wherein, the rotating disk 21 completes one alternating rotation, which is the rotation alternation of the rotating disk 21 from one clockwise rotation to one counterclockwise rotation. By using the counter 5 to automatically record the number of tests, accurate counting is achieved and the efficiency of automated testing is improved.

[0035] Furthermore, the testing device also includes a control switch 6; the control switch 6 is connected to the driving member 22 and is used to control the start and stop of the driving member 22. The start and stop of the driving member 22 are controlled by the control switch 6, which is convenient for the staff to operate.

[0036] Among them, Figure 3 As shown, in order to improve the stability of the linkage between the linkage belt 3 and the rotating disk 21, an array of active teeth 7 is provided on the outer circumferential surface of the rotating disk 21; a surface array of one side of the linkage belt 3 that is attached to the rotating disk 21 is provided with linkage teeth 8, and the linkage teeth 8 are meshed with the active teeth 7, so that the linkage belt 3 can be firmly meshed with the outer periphery of the rotating disk 21, thereby improving the stability of the linkage between the two.

[0037] Specifically, Figure 1 and Figure 2 As shown, the driving member 22 includes a driving motor 221 for alternately driving the rotating disk 21 to rotate clockwise and counterclockwise; and a relay 222 connected to the driving motor 221, and the relay 222 is used to control the commutation output of the driving motor 221. In this embodiment, the driving motor 221 adopts a stepping motor to control the rotating disk 21 to rotate one circle clockwise and one circle counterclockwise. Among them, when the time taken for analyzing the driving click to rotate forward / reverse for one circle is N seconds, the commutation of the driving motor 221 can be accurately controlled by the relay 222 combined with the N seconds time to achieve smooth alternation of forward and reverse directions, thereby facilitating multiple cycles of bending deformation testing of the product to be tested and improving the test efficiency.

[0038] Specifically, the rotating disc 21 includes two roller discs, which are arranged on the surface of the base 1 at a preset interval, and one of the roller discs is connected to the driving motor 221 so as to be driven to rotate by the driving motor 221; the linkage belt 3 is an annular belt, which is integrally fitted on the outer circular surfaces of the two roller discs to move with the rotation of the roller discs, so that when the driving motor 221 drives one of the roller discs to rotate, it can drive the linkage belt 3 to move and synchronously drive the other roller disc to rotate.

[0039] In order to facilitate the fixation of the product to be tested, in the present embodiment, the clamping member 4 includes a first clamp 41 and a second clamp 42; the first clamp 41 and the second clamp 42 are arranged on the linkage belt 3 and on both sides of the line connecting the center points of the two roller disks, so as to fix the two ends of the product to be tested respectively; specifically, the first clamp 41 and the second clamp 42 both include a connecting block 43 fixed on the linkage belt 3 and a bolt assembly 44 provided on the connecting block 43; the bolt assembly 44 is used to fix the product to be tested on the connecting block 43, and through the installation of the bolt assembly 44, it is convenient to disassemble and assemble the product to be tested on the connecting block 43, thereby improving the convenience of operation.

[0040] Furthermore, the distance between the first clamp 41 and the two roller discs, and the distance between the second clamp 42 and the two roller discs are both greater than the outer circumference of the roller discs, so that when the roller discs rotate one circle, the first clamp 41 and the second clamp 42 will not contact the roller discs, thereby ensuring that the product to be tested can be stably tested multiple times, thereby improving the convenience of testing.

[0041] The bending test device provided in this embodiment uses a clamping member 4 to fix the product to be tested on the linkage belt 3, so as to start the driving member 22 to drive the rotating disc 21 to rotate, so that the rotating disc 21 drives the linkage belt 3 to move around the rotating disc 21, so that the product to be tested moves with the linkage belt 3 to bend and deform, so as to realize automatic bending test, reduce personnel costs, and use mechanical transmission to drive the product to be tested to bend and deform, which is more conducive to repeating the bending test for multiple times, and each test process can be kept consistent, which not only speeds up the operation speed of the bending test, but also greatly shortens the experimental cycle, so that the reliability and stability of the experimental results are significantly enhanced, so as to improve the test reliability, greatly reduce the personnel cost, and improve the product detection efficiency. In addition, it is also equipped with a counter 5, which can automatically record the number of tests to achieve the effect of accurate counting. At the same time, it cooperates with the relay 222 to accurately control the commutation of the driving motor 221, and can lock the time and bending requirements of the product to be tested to complete a bending test, so as to improve the reliability and accuracy of the test.
