Description

Technical Field

[0001] The utility model relates to the technical field of equipment parts and components, in particular to a multi-axis automatic screw driving device. Background Art

[0002] Screws, as a common fastener, are easily installed, removed, and adjusted, making them widely used in equipment assembly. Their primary function is to securely connect different parts together, ensuring the structural stability and functional integrity of the equipment. Furthermore, by tightening or loosening screws, the position, angle, or spacing of parts can be fine-tuned to achieve precise assembly requirements. Although small, screws are indispensable in modern industry and daily life, providing reliable support for the stable operation of various structures and equipment.

[0003] However, in the existing parts assembly process, screw driving operations are usually performed manually. The manual operation speed is relatively slow, and only one screw can be processed at a time. It is impossible to tighten multiple screws at the same time. The overall operation efficiency is low and it is difficult to meet the fast production rhythm requirements. Utility Model Content

[0004] (1) Technical problems solved

[0005] In response to the shortcomings of the existing technology, the utility model provides a multi-axis automatic screw driving device, which can solve the problem that the overall operation efficiency is low and it is difficult to meet the fast production rhythm requirements when manual screw driving is used in the existing parts assembly process. It can tighten multiple screws at the same time, greatly improving production efficiency, and can accurately control the tightening torque and depth of each screw to ensure the consistency and accuracy of screw tightening.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a multi-axis automatic screw driving device, comprising a guide shaft, a positioning tool provided on one side of the guide shaft, a matching motor installed inside the positioning tool, a spacing adjustment assembly connected to the upper end of the guide shaft, the spacing adjustment assembly including a cylinder, a first support plate and a second support plate connected to the lower end of the cylinder;

[0008] A servo tightening assembly is installed on the upper surface of the first support plate, and a feeding assembly is connected to the second support plate. A screw body is arranged inside the feeding assembly. The servo tightening assembly is used to tighten the screw body, and the feeding assembly is used to feed. The spacing adjustment assembly is used to adjust the position of the servo tightening assembly and the feeding assembly.

[0009] Through the above technical solution, when assembling the screw body, the matching motor on which the screw needs to be installed is first installed inside the positioning tooling, and then the positioning tooling loaded with the matching motor is smoothly transferred to the screw driving station through the conveying device. Then the spacing adjustment component adjusts the servo tightening component and the feeding component to the specified position, and then the feeding component starts working to transport the screw body to the specified position. Finally, the servo tightening component starts working to tighten multiple screw bodies at the same time. When the matching motor and the screw body are assembled, the conveying device moves the matching motor to the next station through the positioning tooling for subsequent processing or operation.

[0010] Furthermore, the cylinder is connected to the guide shaft in a fixed manner, the lower surfaces of the first support plate and the second support plate are fixedly connected with a sliding sleeve respectively, the sliding sleeve is connected to the guide shaft in a sliding manner, and the guide shaft is symmetrically distributed about the longitudinal center line of the first support plate.

[0011] Through the above technical solution, the cylinder can push the first support plate and the second support plate to move, so that the sleeve slides on the outer surface of the guide shaft. The movement of the first support plate and the second support plate can be guided by the guide shaft, thereby precisely adjusting the position of the servo tightening assembly and the feeding assembly.

[0012] Furthermore, the first support plate is located above the second support plate, and the size of the first support plate is equal to the size of the second support plate.

[0013] Through the above technical solution, since the servo tightening assembly and the feeding assembly are vertically distributed, the vertical space can be used more effectively, making the structure of the entire equipment more compact. At the same time, interference and collision with other horizontally arranged components can be avoided, reducing the possibility of failure.

[0014] Furthermore, the servo tightening assembly includes a servo motor, one end of the servo motor is connected to a transmission rod, the lower end of the transmission rod is connected to a tightening mouth, a discharge trough is provided inside the tightening mouth, the screw body is located at the end of the discharge trough, and a screwdriver is connected inside the tightening mouth.

[0015] Through the above technical solution, after the feeding assembly blows out the screw body, the servo motor starts to rotate. The servo motor has high-precision position and speed control capabilities, which can ensure that the rotation angle and speed are accurate. While the servo motor rotates, it will drive the screw body to be tightened onto the matching motor, and multiple servo motors can be used to tighten multiple screw bodies at the same time, which can greatly improve production efficiency.

[0016] Furthermore, the feeding assembly includes a conveying pipe, the lower end of the conveying pipe is connected to a discharge nozzle, and a screw bin is provided inside the discharge nozzle.

[0017] Through the above technical solution, the delivery pipe is connected to the nail feeding mechanism, which stores a certain number of screw bodies inside. Through precise control, 3 screw bodies can be blown out to the designated position each time.

[0018] Furthermore, a mechanical stopper is fixedly connected to the outer surface of the delivery pipe, and the mechanical stopper and the delivery pipe form a vertical structure.

[0019] Through the above technical solution, the mechanical stopper is used to separate the continuous screw bodies one by one, ensuring that the number of screw bodies output each time meets the requirements.

[0020] Furthermore, the feeding nozzle and the tightening nozzle are connected to each other, the feeding nozzle is inclined, and the tightening nozzle is vertical.

[0021] Through the above technical solution, the screw body enters the tightening nozzle through the blanking nozzle, thereby facilitating the subsequent tightening work of the screw body.

[0022] Furthermore, the transmission rod passes through the second support plate, and a connecting plate is sleeved on the outer surface of the transmission rod, and the connecting plate and the second support plate are connected to each other.

[0023] Through the above technical solution, the transmission rod can be limited by the connecting plate, thereby ensuring that the transmission rod is stable in a specified position.

[0024] Compared with the prior art, the present invention provides a multi-axis automatic screw driving device with the following beneficial effects:

[0025] In the utility model, the matching motor can be fixed by the positioning tool. After the matching motor is smoothly transferred to the screw driving station, the servo tightening component and the feeding component can be adjusted to the specified position through the spacing adjustment component. The screw body can be transported to the specified position through the feeding component. The servo tightening component can tighten multiple screw bodies at the same time, which greatly improves production efficiency. The servo motor has high-precision position and speed control capabilities, which can ensure that the rotation angle and speed are accurate, and can accurately control the tightening torque and depth of each screw to ensure the consistency and accuracy of screw tightening.

[0033] 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.

[0034] See also Figures 1-6 The utility model provides a technical solution: a multi-axis automatic screw driving device, comprising a guide shaft 1, a positioning tool 2 is provided on one side of the guide shaft 1, a matching motor 3 is installed inside the positioning tool 2, the upper end of the guide shaft 1 is connected to a spacing adjustment component, the spacing adjustment component includes a cylinder 4, and the lower end of the cylinder 4 is connected to a first support plate 5 and a second support plate 6;

[0035] A servo tightening assembly is installed on the upper surface of the first support plate 5. The second support plate 6 is connected to a feeding assembly. A screw body 17 is provided inside the feeding assembly. The servo tightening assembly is used to tighten the screw body 17, and the feeding assembly is used to feed. The spacing adjustment assembly is used to adjust the position of the servo tightening assembly and the feeding assembly.

[0036] It is worth mentioning that: when assembling the screw body 17, first install the matching motor 3 on which the screw needs to be installed into the interior of the positioning tooling 2, and then use the conveying device to smoothly transfer the positioning tooling 2 loaded with the matching motor 3 to the screw driving station, and then the spacing adjustment component adjusts the servo tightening component and the feeding component to the specified position, and then the feeding component starts working to transport the screw body 17 to the specified position, and finally the servo tightening component starts working to tighten multiple screw bodies 17 at the same time. When the matching motor 3 and the screw body 17 are assembled, the conveying device moves the matching motor 3 to the next station through the positioning tooling 2 for subsequent processing or operation.

[0037] See also Figure 1-Figure 2 The connection between the cylinder 4 and the guide shaft 1 is a fixed connection. The lower surfaces of the first support plate 5 and the second support plate 6 are respectively fixedly connected with a sliding sleeve 7. The connection between the sliding sleeve 7 and the guide shaft 1 is a sliding connection. The guide shaft 1 is symmetrically distributed about the longitudinal center line of the first support plate 5. The first support plate 5 is located above the second support plate 6, and the size of the first support plate 5 is equal to that of the second support plate 6.

[0038] It should be noted that: since the servo tightening assembly and the feeding assembly are distributed vertically, the vertical space can be utilized more effectively, making the structure of the entire equipment more compact. At the same time, interference and collision with other horizontally arranged components can be avoided, reducing the possibility of failure. The cylinder 4 can push the first support plate 5 and the second support plate 6 to move, so that the sleeve 7 slides on the outer surface of the guide shaft 1. The movement of the first support plate 5 and the second support plate 6 can be guided by the guide shaft 1, so that the position of the servo tightening assembly and the feeding assembly can be accurately adjusted.

[0039] See also Figures 1-6 The feeding assembly includes a conveying pipe 8, the lower end of the conveying pipe 8 is connected to a discharge nozzle 9, a screw bin 10 is provided inside the discharge nozzle 9, the outer surface of the conveying pipe 8 is fixedly connected to a mechanical stopper 11, the mechanical stopper 11 and the conveying pipe 8 form a vertical structure, the discharge nozzle 9 and the tightening nozzle 14 are connected to each other, the discharge nozzle 9 is inclined, and the tightening nozzle 14 is vertical.

[0040] The principle of feeding is: when the matching motor 3 reaches the screw driving station, the feeding assembly starts to work, and the delivery pipe 8 is connected to the nail feeding mechanism. A certain number of screw bodies 17 are stored inside the nail feeding mechanism, and through precise control, 3 screw bodies 17 can be blown out to the specified position each time, and the mechanical stopper 11 is used to separate the continuous screw bodies 17 one by one to ensure that the number of screw bodies 17 output each time meets the requirements. The screw body 17 enters the tightening nozzle 14 through the feeding nozzle 9, thereby facilitating the subsequent tightening of the screw body 17.

[0041] See also Figures 1-6 The servo tightening assembly includes a servo motor 12, one end of the servo motor 12 is connected to a transmission rod 13, the lower end of the transmission rod 13 is connected to a tightening nozzle 14, a discharge trough 15 is provided inside the tightening nozzle 14, the screw body 17 is located at the end of the discharge trough 15, a screwdriver 16 is connected to the inside of the tightening nozzle 14, the transmission rod 13 passes through the second support plate 6, and the outer surface of the transmission rod 13 is sleeved with a connecting plate 18, and the connecting plate 18 is connected to the second support plate 6.

[0042] The principle of tightening the screw body 17 is: after the feeding assembly blows out the screw body 17, the screw body 17 will be stored at the end of the discharge trough 15, and then the servo motor 12 starts to rotate. The servo motor 12 has high-precision position and speed control capabilities, which can ensure that the rotation angle and speed are accurate. While the servo motor 12 rotates, it will drive the screw body 17 to be tightened to the matching motor 3 through the screwdriver 16, and multiple servo motors 12 can simultaneously tighten multiple screw bodies 17, which can greatly improve production efficiency.
