[0002] With the booming development of skateboarding, the demand for skateboard production is increasing daily. However, the skateboard manufacturing industry is currently facing many challenges. The traditional method of tightening skateboard wheel bolts relies on manual operation, which is inadequate under the requirements of modern high-efficiency production. In order to improve the efficiency and quality of skateboard production and meet market demand, we must seek new solutions.

[0003] Currently, in the skateboard manufacturing industry, the traditional method of manually tightening skateboard roller bolts is inefficient and difficult to guarantee consistent quality. On the one hand, manual bolt tightening is not only time-consuming and labor-intensive, but also prone to inconsistent tightening, affecting the performance and safety of the skateboard. On the other hand, in modern industrial production, improving production efficiency, reducing costs, and ensuring product quality stability are key objectives. To address the shortcomings of existing technologies, we propose an automatic skateboard roller bolt tightening device. Utility Model Content

[0004] The main purpose of this utility model is to provide an automatic fastening device for skateboard roller bolts, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatic bolt tightening device for skateboard rollers includes a workbench, a skateboard body, and several rollers. The skateboard body is mounted on the workbench. The device also includes a six-axis robotic arm, a handling robot for moving the skateboard body, and an assembly robot. The six-axis robotic arm is mounted on one side of the workbench and has an electric wrench connected to its end. The assembly robot is mounted above the workbench and has a two-finger mechanical claw connected to its end for gripping the rollers. Several rollers are neatly arranged on one side of the workbench.

[0007] The workbench is fixedly equipped with a positioning groove plate for positioning and installing the slide plate body, and the slide plate body is positioned and placed in the positioning groove plate.

[0008] Preferably, a connecting shaft is fixedly installed on the output shaft of the electric wrench, and a groove is provided at the end of the connecting shaft.

[0009] Preferably, a rectangular post is fixedly installed at the top of the sleeve, and a locking tongue, a sliding groove and a small spring are provided at the top of the rectangular post. The back of the locking tongue is telescopically connected to the sliding groove in the rectangular post. A first magnetic post is fixedly installed on the back of the locking tongue, and a second magnetic post is fixedly installed on the inner wall of the sliding groove. The first magnetic post and the second magnetic post attract each other. The two ends of the small spring are respectively compressed and sleeved on the two ends of the first magnetic post and the second magnetic post.

[0010] Preferably, a swivel plate is fixedly installed on one side of the workbench, and a plurality of strip grooves are provided on the upper surface of the swivel plate, and a plurality of rollers are neatly arranged in the plurality of strip grooves.

[0011] Preferably, an inclined block is fixedly installed protruding inward on the inner wall of the slot, and a large spring is fixedly installed on the inner top surface of the slot.

[0012] Preferably, a magnetic disk is fixedly installed on one side of the workbench.

[0013] Preferably, a torque sensor is coaxially fixedly mounted on the top end of the connecting shaft.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, through the collaborative work of multiple automated components, greatly improves production efficiency and ensures the consistency of bolt tightening. The six-axis robotic arms and the device for transporting the sliding plate are respectively set on both sides of the workbench, and together with the assembly robot at the top, realize a series of operations such as transporting the sliding plate, gripping and installing the rollers, and automatically tightening the bolts.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1-6As shown, an automatic bolt tightening device for skateboard rollers includes a workbench 1 as the core support structure. A six-axis robotic arm 6 and a skateboard body 3 for transporting the skateboard are fixedly connected to the left and right sides of the workbench 1, respectively. An assembly robot 11 is fixedly installed at the top of the workbench 1. An electric wrench 7 is fixedly installed at the end of the six-axis robotic arm 6, ready to tighten the skateboard roller bolts at any time. A two-finger mechanical claw 12 for gripping the roller 5 is connected to the end of the assembly robot 11. The two-finger mechanical claw 12, in conjunction with the assembly robot 11, can accurately grip the roller 5. An electric wrench 7 is fixedly installed at the end of the skateboard body 3 for transporting the skateboard. The vacuum suction cup 9 can firmly hold the slide plate 3, ensuring the stability of the slide plate during transportation. The positioning slot plate 2 is fixedly installed on the workbench 1, and the slide plate 3 is positioned and installed in the positioning slot plate 2 to set the slide plate 3 on the workbench 1. The swing plate 4 is fixedly installed on one side of the workbench 1. Several strip grooves are provided in the upper surface of the swing plate 4. Several rollers 5 are neatly arranged in the several strip grooves, ready to be grabbed and installed at any time. The magnetic plate 13 is fixedly installed on one side of the workbench 1 to attract the connecting sleeve 702 by magnetic force.

[0026] It should be noted that the automatic bolt tightening device for skateboard rollers has a highly efficient and orderly workflow. First, the handling robot 8 uses a vacuum suction cup 9 to transport the skateboard body 3 to the positioning slot plate 2 for positioning. The handling robot 8 and the vacuum suction cup 9 then press and fix the skateboard body 3 onto the positioning slot plate 2. Next, the assembly robot 11 operates a two-finger mechanical claw 12 to grab the roller 5 from the tray 4 and then accurately installs the roller 5 into the corresponding position on the skateboard body 3. Finally, the six-axis robotic arm 6 drives the electric wrench 7 to automatically tighten the roller bolts. The entire process requires no manual intervention, greatly improving production efficiency and quality, and providing reliable technical support for the mass production of skateboards.

[0027] refer to Figure 3 and Figure 5 A connecting shaft 701 is coaxially fixedly installed on the output shaft of the electric wrench 7. A groove 704 is provided at the end of the connecting shaft 701. An inlet 713 with a reduced cross-sectional size is connected to the end of the groove 704. A sleeve 702 is detachably connected in the groove 704 and the inlet 713. A rectangular post 706 is fixedly installed at the top of the sleeve 702. The rectangular post 706 is fitted and slides through the inlet 713 to ensure the accuracy and stability of the connection between the sleeve 702 and the connecting shaft 701.

[0028] refer to Figure 4 , Figure 5 and Figure 6The top of the rectangular column 706 is provided with a locking tongue 707, a slide groove 708 and a small spring 711. The back of the locking tongue 707 is telescopically connected to the slide groove 708 in the rectangular column 706. A magnetic column 1 709 is fixedly installed on the back of the locking tongue 707. A magnetic column 2 710 is fixedly installed on the inner wall of the slide groove 708. The magnetic column 1 709 and the magnetic column 2 710 attract each other. The two ends of the small spring 711 are respectively compressed and sleeved on the two ends of the magnetic column 1 709 and the magnetic column 2 710. The two ends of the small spring 711 are respectively compressed and connected to the inner wall of the locking tongue 707 and the slide groove 708. A wedge block 705 is fixedly installed inwardly on the inner wall of the slot 704. A large spring 712 is fixedly installed on the inner top surface of the slot 704. A torque sensor 703 is coaxially fixedly installed on the top of the connecting shaft 701. The torque sensor 703 can monitor the tightening force in real time to ensure the consistency of bolt tightening.

[0029] This application utilizes the hysteresis of spring rebound, that is, the small spring 711 cannot immediately return to its original state after being compressed, but needs a period of time to complete the rebound. Then, the magnetic force between the first magnet 709 and the second magnet 710 attracts each other to offset part of the elastic force of the small spring 711 after being compressed, thereby prolonging the hysteresis time of the small spring 711 rebound. The magnetic force between the first magnet 709 and the second magnet 710 attracts each other slightly less than the rebound force of the small spring 711 after being compressed.

[0030] In this invention, firstly, the vacuum suction cup 9 of the handling robot 8 transports the skateboard body 3 to the positioning slot plate 2 for positioning. Then, the handling robot 8 and the vacuum suction cup 9 press and fix the skateboard body 3 onto the positioning slot plate 2. Next, the assembly robot 11 operates the two-finger mechanical claw 12 to grab the roller 5 from the swing plate 4, and then accurately installs the roller 5 into the corresponding position of the skateboard body 3. Finally, the six-axis robotic arm 6 drives the electric wrench 7 to automatically tighten the roller bolts. The entire process requires no manual intervention, which greatly improves production efficiency and quality, and provides reliable technical support for the mass production of skateboards.

[0031] When the electric wrench 7 needs to disassemble the socket 702, the six-axis robotic arm 6 first places the end of the socket 702 against the magnetic disk 13 and applies pressure, pressing the connecting shaft 701 at the end of the electric wrench 7 and the rectangular post 706 in the socket 702 against each other. This causes the inclined block 705 in the inner wall of the rectangular post 706 and the inclined surface of the telescopic connecting locking tongue 707 in the rectangular post 706 to be opposite, compressing the telescopic connecting locking tongue 707 in the rectangular post 706 into the slide groove 708, and bringing the magnetic post 709 on the locking tongue 707 close to the contact groove 708. The second magnetic post 710 in 8 releases the restriction of the locking tongue 707 on the rectangular post 706 being pulled out of the slot 704. Then, by utilizing the lag of the rebound of the small spring 711 and the magnetic attraction of the first magnetic post 709 and the second magnetic post 710, the reset time of the small spring 711 and the locking tongue 707 can be extended. During the lag of the rebound of the small spring 711, the rectangular post 706 at the top of the sleeve 702 can be easily pulled out from the slot 704 of the connecting shaft 701 at the end of the electric wrench 7, thereby realizing the automatic disengagement of the sleeve 702.

[0032] When the electric wrench 7 needs to install the socket 702, simply align the groove 704 of the connecting shaft 701 at the end of the electric wrench 7 with the rectangular post 706 at the top of the socket 702, and compress the locking tongue 707 into the groove 704. After the hysteresis of the small spring 711 on the back of the locking tongue 707 is over, the small spring 711 will push the locking tongue 707 to reset, so that the locking tongue 707 and the inclined surface in the inclined block 705 fit together. The elastic force of the large spring 712 will push and press the rectangular post 706 against the inner wall of the groove 704 to maintain stability, providing a reliable guarantee for the efficient operation of the electric wrench 7.
