DETAILED DESCRIPTION

[0049] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0050] like Figure 1-Figure 13 As shown, the present invention provides a mobile wheel life test device, including a clamping mechanism 1, a test belt 2, a feeding mechanism 3, and a storage mechanism; wherein:

[0051] The clamping mechanism 1 is arranged on one side of the test belt 2 to fix the moving wheel 6 to be tested;

[0052] The test belt 2 is located below the moving wheel 6 to be tested, so that the life test is performed when the moving wheel 6 is in contact with the test belt 2;

[0053] The unloading mechanism 3 is arranged at the other side of the test belt 2, and is used to remove the moving wheel 6 that has completed the test from the clamping mechanism 1 and put it onto the test belt 2;

[0054] The storage mechanism is arranged at one end of the test belt 2 and is used to receive the mobile wheel 6 that has completed the test and is transported by the test belt 2 .

[0055] The mobile wheel 6 life test device provided by the present invention comprises a clamping mechanism 1, a test belt 2, a feeding mechanism 3, and a storage mechanism; the clamping mechanism 1 can fix the mobile wheel 6 to be tested onto the test belt 2, and can complete automatic life detection, replacing manual work with automatic testing, thereby realizing automatic life testing of the mobile wheel 6 of a dehumidifier or a mobile machine; the feeding mechanism 3 can realize that the mobile wheel 6 to be tested is removed from the clamping mechanism 1 and placed on the test belt 2, realizing automatic feeding and conveying, realizing full automation of life testing, reducing labor intensity, and improving test efficiency.

[0056] In order to facilitate the fixation of each mechanism, in this embodiment, a support frame 5 is further included, and the test belt 2 is arranged on the top of the support frame 5.

[0057] A support plate is provided on the support frame 5 , and the clamping mechanism 1 and the unloading mechanism 3 are respectively fixed on both ends of the support plate, so that the clamping mechanism 1 and the unloading mechanism 3 are respectively located on both sides of the test belt 2 .

[0058] like Figure 1-Figure 13 As shown, in this embodiment, the clamping mechanism 1 includes a lifting cylinder 11, a connecting plate 12, a driving motor 13, a disk tooling 14, and a limiting structure; wherein:

[0059] The output end of the lifting cylinder 11 is connected to the connecting plate 12, which can drive the connecting plate 12 to move up and down in the vertical direction; the connecting plate 12 is arranged horizontally, and one end is connected to the lifting cylinder;

[0060] The drive motor 13 passes through the connecting plate 12 and is connected to the disk fixture 14, which can drive the disk fixture 14 to rotate horizontally. Furthermore, the drive motor 13 is installed at the other end of the connecting plate 12. The disk fixture 14 is made of a magnetic material, which can be a permanent magnet material. The disk fixture 14 can also adopt an electromagnetic structure. Of course, the electromagnetic structure needs to be equipped with more components and the structure will be more complicated. In this embodiment, only the disk fixture 14 with a permanent magnet is used, for example Figure 7 As shown, the disk fixture 14 is in the shape of a disk, and the entire disk disk fixture 14 can be made of permanent magnets, or a permanent magnet layer can be set at the bottom of the disk-shaped disk fixture 14 to use magnetism to adsorb the moving wheel 6, and the upper part of the moving wheel 6 is made of a magnetically attractive metal material. Of course, the magnetic attraction between the disk fixture 14 and the moving wheel 6 should be greater than the gravity of the moving wheel 6 to prevent the moving wheel 6 from falling due to insufficient attraction when installing it.

[0061] The limiting structure is provided on the disk fixture 14, and is used to limit the moving wheel 6 to be tested which is adsorbed on the bottom of the disk fixture 14. The limiting structure prevents the moving wheel 6 from contacting the test belt 2, and the test belt 2 moves to take the moving wheel 6 away, and the life test cannot be completed.

[0062] In order to further improve the test efficiency, in this embodiment, each disk fixture 14 is provided with a plurality of test stations along the circumference, and each test station is provided with a limit position structure. Fig.11 As shown, four testing stations are arranged on the disk tooling 14, which can complete the life detection of four moving wheels 6 in sequence. After one installation, the detection operation of multiple moving wheels 6 can be completed without the need for personnel supervision, which greatly improves the detection efficiency.

[0063] By setting a plurality of test stations on the disk tooling 14, each test station can fix a moving wheel 6, so that the life detection of multiple moving wheels 6 can be realized in sequence, and the multi-station test replaces the cumbersome process of single moving wheel 6 test, thereby improving the test efficiency. This method can reduce the number of manual tests on the moving wheel 6, and there is no need for personnel to follow up the test during the process, thereby improving the test efficiency.

[0064] Considering that the top of the moving wheel 6 has different structures, in the present invention, there are two forms of the limiting structure, one is a limiting through hole 15 set on the disk fixture 14, and the other is a limiting card slot 16 set at the bottom of the disk fixture 14. If the tested moving wheel 6 has only one top structure, only the limiting through hole 15 or the limiting card slot 16 can be set. However, in order to expand the scope of application, the limiting through hole 15 and the limiting card slot 16 can be set at the same time, such as Fig.11 When the top of the moving wheel 6 is a top column 61 structure, the position can be limited by the limiting through hole 15, such as Fig. 9 If the top of the moving wheel 6 is a rectangular boss, the limiting slot 16 can be used for limiting.

[0065] The movable wheel 6 to be tested in the present invention has two structures, and the disk tooling 14 is designed to meet compatibility. There are four stations under a single disk tooling 14, and four movable wheels 6 can be installed at one time and tested in sequence.

[0066] In order to improve the lifting stability and ensure the stability of the test process, in this embodiment, there are two lifting cylinders 11, which are arranged side by side and spaced apart. The two groups of cylinders can provide a stronger supporting force and ensure the stability of the lifting.

[0067] A group of two lifting cylinders 11 are installed on the connecting plate 12 of the clamping mechanism 1. The lifting cylinders 11 are lifted before the test. The operator places the moving wheel 6 to be tested on the disk tooling 14 for adsorption. The lifting cylinders 11 then descend and press the moving wheel 6 onto the test belt 2 for testing. After the test is completed, the driving motor 13 drives the disk tooling 14 to rotate, and the next moving wheel 6 is tested in this reciprocating manner.

[0068] like Figure 1-Figure 13 As shown, as an optional embodiment of the present invention, the unloading mechanism 3 includes a fixing plate 31, a propulsion cylinder 32, a clamping cylinder 33 and a clamping piece 34; wherein:

[0069] The propulsion cylinder 32 is fixed on the top of the fixed plate 31;

[0070] The clamping claw cylinder 33 is fixed on the propulsion cylinder 32 and can be horizontally extended and retracted under the drive of the propulsion cylinder 32;

[0071] The clamping jaws 34 are connected to the clamping jaw cylinder 33 and can move closer to or farther away from the clamping jaw cylinder 33 to clamp or release the moving wheel 6 .

[0072] When in use, the propulsion cylinder 32 is installed on the fixed plate 31 of the unloading mechanism 3. After the test of the moving wheel 6 is completed, the propulsion cylinder 32 drives the clamping cylinder 33 and the clamping jaw 34 forward. The clamping jaw 34 clamps the moving wheel 6 under the drive of the clamping jaw cylinder 33 and places it on the test belt 2.

[0073] like Fig.13 As shown, the storage mechanism includes a storage box 4.

[0074] In order to further improve the detection efficiency, the number of clamping mechanisms 1 and feeding mechanisms 3 are both two sets, which are arranged one by one along the extension direction of the test belt 2. Of course, in addition to setting two sets, three sets, four sets or more sets can also be set, but when the number of sets is relatively large, the length of the corresponding test belt 2 needs to be longer, and the occupied space will be larger. It is also necessary to consider the space size of the actual layout location and select the optimal number of matching.

[0075] By providing two sets of clamping mechanisms 1, two moving wheels 6 can be tested simultaneously, and multiple rounds of simultaneous testing replace the cumbersome process of a single moving wheel 6 test, thereby improving the test efficiency.

[0076] Furthermore, the present invention also provides a moving wheel life detection method, which is completed by using a moving wheel life test device. Specifically, the moving wheel life detection method includes the following steps:

[0077] Step S1, fixing a plurality of moving wheels 6 on the clamping mechanism 1 to prepare for testing;

[0078] Step S2, when the test preparation is completed, the clamping mechanism 1 is started so that one of the moving wheels 6 is aligned with the test belt 2 and contacts the test belt 2;

[0079] Step S3, starting the test belt 2 to complete the life test of one of the moving wheels 6 under the set speed and time parameters;

[0080] Step S4, when the life test is completed, the test belt 2 is closed, and the unloading mechanism 3 and the clamping mechanism 1 cooperate to remove the moving wheel 6 that has completed the test from the clamping mechanism 1 and put it on the test belt 2;

[0081] Step S5, start the test belt 2 to transport the tested moving wheel 6 to the storage mechanism.

[0082] After completing step S5, return to step S2, start the clamping mechanism 1 to align the other moving wheel 6 with the test belt 2 and contact the test belt 2, and then complete steps S3, S4, and S5 in sequence to complete the life test of the second moving wheel, and then cycle in sequence until the moving wheel tests of the four workstations are completed.

[0083] The detection method provided by the present invention is completed by a mobile wheel 6 life test device, and the mobile wheel 6 life test device adopts a test belt 2, and the test belt 2 can be customized to set the running speed (V) within a certain range. Through two groups of mobile wheel 6 clamping mechanisms 1, each group of clamping mechanisms 1 has a four-station disk tooling 14, and after the lifting cylinder 11 is lifted, the tester places the mobile wheel 6 to be tested on the disk tooling 14, and the disk tooling 14 is provided with a limit through hole 15 and a limit slot 16 to be suitable for the mobile wheel 6 model. During the test, the lifting cylinder 11 falls, the mobile wheel 6 contacts the test belt 2, and the belt line running speed is set. After running to the set time (T), the front push-type unloading mechanism 3 clamps the test mobile wheel 6, and after the lifting cylinder 11 is lifted, the unloading mechanism 3 opens and retracts, and the tested mobile wheel 6 is located on the belt line, and moves along the belt line and falls into the rear storage box 4. After the first station test is completed, the drive motor 13 on the clamping mechanism 1 drives the disk fixture 14 to rotate to the second station to continue testing, and all station tests are completed in this way. The test travel distance of the moving wheel 6 (S=VT) is obtained by calculating the speed and running time, and combined with the wear state of the moving wheel 6 after the test, it is judged whether the life of the moving wheel 6 is greater than the current test distance.
