[0002] A pulley is a mechanical component typically used in conjunction with a drive belt to transmit mechanical power. Common pulley types include V-pulleys, flat pulleys, and synchronous pulleys. During installation, pulleys typically need to be aligned with other components, such as shafts. Inaccurate pulley apertures can result in overtightening or undertightening the pulley and shaft. Overtightening can make installation difficult and even damage the shaft or pulley during installation. Overtightening can cause relative rotation of the pulley on the shaft, resulting in unstable transmission. Using a dimensional inspection device can ensure reliable installation and operation.

[0003] In the prior art, some size detection devices usually use detection rods to detect the aperture of the pulley, but most of the detection rods are fixed in a specified position and then detected, which requires manual placement of the pulley in a suitable position for detection. In addition, when maintaining the detection rod, tools are needed to unscrew the bolts and nuts to remove the detection rod before maintenance can be performed. This process is relatively cumbersome, which increases the complexity and time cost of the operation. Therefore, in response to the above shortcomings, a pulley size detection device is proposed.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figures 1 to 3The present invention provides an embodiment of a pulley size detection device, comprising a workbench 1, the bottom end of which is fixedly connected to a support assembly for bearing, the support assembly being composed of a plurality of support legs 2, which serve to stably support the workbench 1. The bottom ends of the support legs 2 are fixedly connected to support bases 3, which can increase the contact area with the placement surface, thereby better dispersing the pressure. The top ends of the plurality of support legs 2 are fixedly connected to the four corners of the bottom end of the workbench 1. This distribution ensures the stability of the workbench 1 during operation, allowing it to be placed stably in a working environment.

[0025] A support plate 4 is fixedly connected to the rear interior of the workbench 1, providing a mounting base for subsequent components. A receiving hole 5 is defined within the support plate 4, providing space for the movement of internal components. A motor 6 is fixedly connected to the rear end of the support plate 4, serving as the power source and providing the necessary support for the movement of the entire device. A gear 7 is fixedly connected to the drive end of the motor 6, whose outer rotatable connection is internal to the right side of the receiving hole 5. This rotational connection allows the gear 7 to rotate freely within the receiving hole 5. A sliding plate 8 is slidably connected to the interior of the receiving hole 5. The sliding movement of the sliding plate 8 within the receiving hole 5 is a key component of the height adjustment mechanism. The outer slidable connection of the sliding plate 8 is to the inner wall of the top of the support plate 4. This sliding connection ensures the stability of the sliding plate 8 during movement. A limit block 9 is fixedly connected to the left side of the sliding plate 8, whose outer slidable connection is internal to the receiving hole 5. This limit block 9 limits the range of motion of the sliding plate 8, preventing it from excessively deflecting or falling off the track during movement. A rack plate 10 is fixedly connected to the right interior of the sliding plate 8. The gear 7 and rack plate 10 are meshed, converting the rotation of the gear 7 into linear motion of the rack plate 10. A support plate 11 is fixed to the front side of the rack plate 10. This support plate 11 moves with the movement of the rack plate 10, allowing for height adjustment. This height adjustment ensures that the detection rod on the load block 13 contacts the pulley aperture at the optimal position, ensuring detection accuracy.

[0026] An electric push rod 12 is fixedly connected to the rear side of the carrier plate 11. Electric push rod 12 serves as another power device, controlling the forward and backward movement of the load block 13. The driving end of electric push rod 12 is fixedly connected to the load block 13. The outer portion of the load block 13 is slidably connected to the inner portion of the carrier plate 11. This sliding connection enables the load block 13 to move smoothly within the carrier plate 11. Sliding blocks 14 are fixedly connected to the left and right sides of the load block 13. Sliding holes 15 are provided on both sides of the carrier plate 11. The outer portion of the sliding block 14 is slidably connected to the inner portion of the sliding hole 15. The cooperation between the sliding block 14 and the sliding hole 15 further ensures the stability of the load block 13 during movement. The internal thread of the load block 13 is connected to a bolt 16, the bottom end of the bolt 16 is fixedly connected to the detection block 17, the external thread of the bolt 16 is connected to a nut 18, the bottom end of the nut 18 contacts the top end of the load block 13, and the external end of the nut 18 is fixedly connected to a twisting rod 19. This structural design facilitates the installation and removal of the detection rod;

[0027] Auxiliary components are fixedly connected to the left and right sides of the supporting plate 11, and the auxiliary components include a support block 20. A support rod 21 slides inside the support block 20, and a baffle 22 is fixedly connected to the top of the support rod 21. The bottom ends of the two support rods 21 are fixedly connected to the top of the workbench 1, and the top of the support block 20 contacts the bottom end of the baffle 22. The auxiliary components can provide additional support for the supporting plate 11 and enhance its stability during movement.

[0028] Reference Figure 1 、 Figure 3 and Figure 5The top of the workbench 1 is fixedly connected to a fixed disk 23, which provides a basic structure for fixing the pulley. The bottom end of the workbench 1 is fixedly connected to an electric push rod 24, which serves as a power device for controlling the fixing and loosening of the pulley. The top of the electric push rod 24 is fixedly connected to a T-block 25, and the outer part of the T-block 25 is slidably connected to the inside of the bottom end of the fixed disk 23. This sliding connection method allows the T-block 25 to slide up and down inside the fixed disk 23. The inside of the fixed disk 23 is slidably connected to a disc 26, and the sliding of the disc 26 inside the fixed disk 23 plays an important role in fixing and loosening the pulley. The top of the T-block 25 is fixedly connected to the bottom end of the disc 26. This connection method ensures that the T-block 25 and the disc 26 can move synchronously. Two oblique holes 27 are provided at the bottom end of the disc 26, and the inner walls on both sides of the fixed disc 23 are slidably connected with extrusion blocks 28. The outside of the T-block 25 is in contact with the adjacent side of the two extrusion blocks 28, and the outside of the oblique hole 1 27 is in contact with the outside of the extrusion block 28. The adjacent side of the two extrusion blocks 28 is provided with an oblique hole 29, and the outside of the oblique hole 29 is in contact with the outside of the bottom end of the disc 26. This complex structural design is pushed by the electric push rod 24 to achieve stable fixation and easy release of the pulley, avoiding displacement or shaking of the pulley due to loose fixation during the detection process, ensuring that the detection rod accurately measures the aperture size and improves the detection accuracy.

[0029] Working principle: First, the motor 6 is started, and the driving end of the motor 6 drives the gear 7 to rotate. The gear 7 rotates inside the right side of the accommodating hole 5. Since the gear 7 is meshed with the rack plate 10, the rotation of the gear 7 drives the rack plate 10 to slide in the accommodating hole 5. The rack plate 10 drives the sliding plate 8 to slide on the top inner wall of the support plate 4. The limit block 9 on the left side of the sliding plate 8 slides in the accommodating hole 5 to play a limiting role. The load-bearing plate 11 on the front side of the rack plate 10 moves with the rack plate 10 to realize the height adjustment of the load-bearing plate 11, so that the detection rod on the loading block 13 can contact the pulley aperture at the optimal position to ensure the accuracy of the detection.

[0030] Next, the electric push rod 12 is started, and the driving end of the electric push rod 12 pushes the loading block 13 to slide inside the supporting plate 11. The sliding blocks 14 on the left and right sides of the loading block 13 slide in the sliding holes 15 on both sides of the supporting plate 11, realizing the forward and backward movement of the loading block 13, thereby making the detection rod move forward and backward, improving the convenience of the detection process and reducing the difficulty of manual operation.

[0031] When the detection rod needs to be disassembled for maintenance, the twisting rod 19 is rotated, and the twisting rod 19 drives the nut 18 to rotate. Since the nut 18 is threadedly connected to the bolt 16, the rotation of the nut 18 can move the bolt 16 in the loading block 13, thereby realizing the rapid disassembly of the detection rod, reducing the complexity of the maintenance operation and improving the efficiency of the maintenance work.

[0032] When the pulley needs to be fixed for testing, the electric push rod 24 is activated. The top of the electric push rod 24 pushes the T-block 25 upward. The T-block 25 slides inside the bottom end of the fixed disk 23. The T-block 25 pushes the disc 26 to slide upward inside the fixed disk 23. The T-block 25 contacts and squeezes outwards with the extrusion block 28, causing the extrusion block 28 to slide on the left and right inner walls of the fixed disk 23. The extrusion block 28 expands the inside of the pulley outward to complete the fixation of the pulley, avoiding displacement or shaking of the pulley due to loose fixation during the testing process, ensuring that the detection rod accurately measures the aperture size and improving the detection accuracy. When the test is completed and the pulley needs to be released, the electric push rod 24 causes the disc 26 to slide downward. The oblique hole 1 27 opened at the bottom of the disc 26 fits with the oblique hole 2 29 opened on the T-block 25, causing the extrusion block 28 to move and release the fixation of the pulley.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
