Description

Technical Field

[0001] This utility model relates to the field of threaded pulley technology, specifically to a threaded pulley detection device. Background Technology

[0002] Tapered sleeve pulleys, also known as threaded pulleys, are mechanical connection assemblies in which a tapered sleeve is embedded between the mounting shaft and the pulley. The pulley is self-locked to the tapered sleeve by an internal hexagonal screw, and the tapered sleeve holds the mounting shaft tightly. During the production process, it is necessary to check whether the pitch and width of the external threads meet the standards.

[0003] For example, Chinese patent CN221649399U discloses a threaded pulley detection device. In this device, a first telescopic cylinder is activated, which moves a lifting and fixing block upward. During the upward movement of the lifting and fixing block, a connecting rod rotatably connected to its outer wall also moves upward. The upward movement of the connecting rod causes one end of it to pull a first horizontal shaft. After the first horizontal shaft is subjected to force, a slider is subjected to force, and the slider is subjected to force, which in turn causes a sliding baffle to be subjected to force. After the sliding baffle is subjected to force, it slides against the surface of the transmission track through a second horizontal shaft. At this time, the sliding baffles on both sides move closer to each other, and the two sliding baffles coming closer to each other cause the threaded pulleys that are irregularly distributed on the surface of the transmission track to come into contact.

[0004] However, in the use of existing threaded pulley detection devices, if the pulleys are placed disorderly on the upper side of the transmission track, it is difficult to accurately move them to the middle of the sliding baffle; moreover, due to the differences in pulley specifications, the existing detection plates are difficult to adapt and cannot effectively meet the detection needs of pulleys of different specifications, so there is still room for further improvement.

[0005] Therefore, we propose a threaded pulley detection device to solve the problems mentioned above. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1-5 This utility model provides a technical solution: a threaded pulley detection device, comprising: a base plate 1, a transmission roller assembly 2, a transmission track 3, a first transmission pulley 4, a second transmission pulley 5, a drive motor 6, a mounting block 7, a first motor 8, a first bidirectional threaded rod 9, a first connecting frame 10, a guide plate 11, a second connecting frame 12, a limiting slide rod 13, a mounting frame 14, a second motor 15, a second bidirectional threaded rod 16, a detection plate body 17, a slot 18, a limiting rod 19, and a pulley to be detected 20.

[0019] In the use of existing threaded pulley detection devices, if the pulleys are placed disorderly on the transmission track 3, it is difficult to accurately move them to the middle of the sliding baffle. Moreover, due to the differences in pulley specifications, the existing detection plates are difficult to adapt and cannot effectively meet the detection requirements of pulleys of different specifications. Therefore, there is still room for further improvement.

[0020] When using a threaded pulley testing device, such as Figure 1 , Figure 2 and Figure 5 As shown, when performing pulley inspection, the first step is to load the pulley 20 to be inspected. The pulley 20 can be placed on the upper side of the transmission track 3 without needing to be sorted. The drive motor 6 on the upper side of the base plate 1 is started. The output shaft of the drive motor 6 drives the second transmission pulley 5 to rotate. The second transmission pulley 5 is connected to the first transmission pulley 4, which in turn drives the first transmission pulley 4 to rotate. The transmission roller assembly 2 rotates synchronously with the first transmission pulley 4, causing the transmission track 3 to start running and conveying the pulley 20 to be inspected to the bottom of the guide mechanism.

[0021] like Figure 1 , Figure 2 and Figure 3As shown, when the pulley 20 to be tested moves to the position corresponding to the guiding mechanism, the first motor 8 on the front side of the mounting block 7 is started. The output shaft of the first motor 8 drives the first bidirectional threaded rod 9 to rotate on the mounting block 7. The first bidirectional threaded rod 9 is threadedly driven by the first connecting frame 10. Since the threads on both sides of the first bidirectional threaded rod 9 are opposite in direction, the two first connecting frames 10 will drive the corresponding guiding plates 11 to move closer together. At the same time, the second connecting frame 12, which is fixedly connected to the guiding plate 11, slides within the limiting slide rod 13 to ensure that the guiding plate 11 moves smoothly. The two guiding plates 11 gradually move closer together, pushing the disordered pulley 20 to be tested to the center position of the transmission track 3, completing the precise alignment of the pulley 20 to be tested, and preparing for subsequent testing.

[0022] like Figure 1 , Figure 4 and Figure 5 As shown, the adjustment mechanism is adjusted to suit the testing requirements according to the specifications of the pulley 20 to be tested. The second motor 15 on the lower side of the mounting bracket 14 is started. The output shaft of the second motor 15 drives the second bidirectional threaded rod 16 to rotate on the mounting bracket 14. The second bidirectional threaded rod 16 is threadedly driven to the detection plate body 17. Since the detection plate body 17 is slidably connected to the limiting rod 19, the limiting rod 19 restricts the rotation of the detection plate body 17, causing the detection plate body 17 to move back and forth along the limiting rod 19. The distance between the front and rear sides of the detection plate body 17 is adjusted according to the size of the pulley 20 to align the slot 18 on the lower side of the detection plate body 17 with the thread testing area of ​​the pulley 20 to be tested, thus completing the adaptation of the testing specifications.

[0023] After the pulley 20 to be tested is guided by the guiding mechanism, the transmission track 3 continues to transport it to the side of the testing plate body 17. The side of the testing plate body 17 has a slot 18, and this slot 18 is perfectly matched to the number of turns of the thread on the outer wall of the pulley 20 and its position on the side. During testing, if the pulley 20 can smoothly pass through the slot 18 of the testing plate body 17, it indicates that its external thread groove is accurately cut and meets the specifications. If the pulley 20 cannot pass through the slot 18 of the testing plate body 17, it indicates that its external thread groove is inaccurate and it is a defective product. In this case, simply remove the pulley 20 that cannot pass through, and the transmission track 3 can be resumed for further testing. After the test is completed, the qualified pulleys 20 are transported by the transmission track 3 to the end of the device, completing the single batch testing operation. If it is necessary to test pulleys 20 of different specifications, repeat the adjustment steps of the above adjustment mechanism to make the protrusion of the test plate body 17 match the thread parameters of the new specification pulley 20.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
