Description

Technical Field

[0001] The utility model relates to the field of mechanical assembly, in particular to a multi-screw positioning and installation device. Background Art

[0002] Currently, most installation screws are installed one by one. If multiple screws need to be tightened in the same plane and the torque of the screws needs to be precisely controlled, such as anti-loosening installation of motors, electric screwdrivers are often used to tighten the screws one by one. Since each screw is not tightened at the same time during the tightening process, the tightening torque varies greatly. After the screws are tightened, other screws may not be installed normally due to errors. Therefore, it is necessary to pre-tighten and then use an electric screwdriver to re-tighten each screw. The whole process is cumbersome and complicated. For some production line assembly processes, the same workpiece needs to be operated uniformly, which is time-consuming.

[0003] A splicable multi-screw installation and adjustment device with publication number CN114248101A discloses a device including a driving mechanism, an actuator and a display mechanism, wherein the driving mechanism includes a motor and a driving gear; a connecting body is fixedly connected to the end of the motor close to the output shaft; the actuator includes a housing, in which a sun gear, a planetary gear and an outer ring gear are meshed in sequence, and both sides of the connecting body can be snapped into the housing to enable the driving mechanism to drive two actuators at the same time; the display mechanism includes a rotating column and a fixed ring, the peripheral side of the rotating column is provided with a scale, and the upper surface of the fixed ring is fixedly connected to an indicator block that slides along the scale; although it discloses a structure that can simultaneously disassemble and assemble multiple bolts, its structure is complex and the operation is cumbersome, and there are high requirements for the position of the disassembled screws, and the scope of use is relatively narrow. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the device for simultaneously disassembling and assembling a plurality of screws has a relatively complex structure and has high requirements on the positions of the screws, which makes it inconvenient to use.

[0007] Furthermore, the encoding and positioning device is one of optical encoding, magnetic encoding or inductive encoding; through the encoding and positioning device, the geometric displacement of the motion motor can be converted into pulses to achieve precise positioning and ensure the stable operation of the device.

[0008] Furthermore, the first direction and the second direction are arranged perpendicular to each other.

[0009] Furthermore, two parallel beams are installed on the frame, and the guide rail spans the two beams and is slidably connected to the beams; the guide rail is installed on the frame through the beams to ensure that the guide rail can move stably in one direction.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0025] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The utility model provides a multi-screw positioning installation device, such as Figure 1 As shown, the frame 10 includes two parallel beams 11 inside, and a plurality of guide rails 12 are arranged between the two beams 11. Specifically, the guide rails 12 span the two beams 11 and are arranged vertically. The guide rails 12 are slidably connected to the beams 11 so that the guide rails 12 can move along the length direction of the beams 11, and the beams 11 are connected to the ends of the guide rails 12. In this way, the guide rails 12 can enclose more effective areas and can operate more screws 30 at one time. In this embodiment, two guide rails 12 are provided, and an electric screwdriver 20 is installed on the guide rails 12, so that two rows of screws 30 can be disassembled and assembled at the same time.

[0027] Specifically, the frame 10 can be fixedly arranged, and the equipment that needs to disassemble and install screws can be moved according to a preset trajectory to the frame 10. Then the guide rail 12 moves on the beam 11 to align the electric screwdriver 20 on it with the installation position of the screw. Then the electric screwdriver 20 works to disassemble and install the screws 30 on the equipment. Then the equipment continues to move, so that the electric screwdriver 20 works on other screws 30. In other embodiments, the frame 10 can also be connected to a robot to move the device so that it can disassemble and install the screws 30 on the equipment. The specific setting can be made according to the actual situation.

[0028] In order to facilitate the assembly and maintenance of the device, the two ends of the beam 11 are mounted on the frame 10 by bolts, so that the beam 11 can be detachably mounted on the frame 10, which is more convenient when the equipment is repaired and replaced.

[0029] like Figure 2 As shown, an electric slider 13 is installed between the crossbeam 11 and the guide rail 12, and the slider 13 can move along the length direction of the crossbeam 11. The guide rail 12 is installed on the slider 13, so that the guide rail 12 can move along the length direction of the crossbeam 11, wherein a plurality of electric screwdrivers 20 are slidably installed on the guide rail 12, and the electric screwdriver 20 can move according to the installation position of the screws 30 of different equipment, so that it can adapt to more situations, and can also disassemble and install more screws 30 at the same time, effectively improving the work efficiency.

[0030] like Figure 2 and Figure 3 As shown, a motion motor 21 is installed on the guide rail 12. When the motion motor 21 is working, it can move on the guide rail 12. A mounting plate 22 is provided on the motion motor 21. The electric screwdriver 20 is passed through the mounting plate 22. When the motion motor 21 is working, the electric screwdriver 20 moves along the length direction of the guide rail 12.

[0031] In this embodiment, the motion motor 21 is detachably mounted on the mounting plate 22 by bolts, and the electric screwdriver 20 is also mounted on the mounting plate 22 by bolts, so that the motion motor 21 can be easily inspected and replaced, and different models of electric screwdrivers 20 can be easily replaced.

[0032] like Figure 2 and Figure 3 As shown, a coding positioning device 23 is provided on the motion motor 21 and the guide rail 12 to determine the position of the motion motor 21 and the guide rail 12. Since the screw installation positions between different devices are different, the motion motor 21 needs to be frequently moved to adapt to the installation positions of the screws 30 of different devices. This may easily lead to the movement position of the motion motor 21 being inaccurate, affecting the normal use of the equipment. Through the coding positioning device 23, the geometric displacement of the motion motor 21 and the guide rail 12 can be converted into pulses to achieve precise positioning and ensure the stable operation of the equipment. The coding positioning device is one of optical coding, magnetic coding or inductive coding.

[0033] like Figure 1 and Figure 4 As shown, a control panel 14 is provided on the frame 10, and the control panel 14 has built-in data input structure, data transmission structure, data storage structure and data display structure, etc. The movement displacement can be input on the control panel 14, so that the electric screwdriver 20 can automatically move to a preset position. By calling different stored data, batch screw disassembly and assembly can be performed on different types of equipment, which greatly improves work efficiency.

[0034] The present device can realize the simultaneous disassembly and assembly of multiple screws. Although the overall device is rectangular and more suitable for screws arranged in rows, it can also be applied to screws distributed in circular, triangular, elliptical and other shapes through a preset program. Specifically, since the guide rail 12 is displaced in the length direction relative to the crossbeam 11, and the electric screwdriver 20 is displaced in the length direction perpendicular to the crossbeam 11, the electric screwdriver 20 can stay at any position in the plane during use. Therefore, the electric screwdriver 20 can be moved to a specified position for disassembly and assembly of screws distributed in different shapes, and has a wider adaptability.

[0035] It should be understood that the above description of the specific embodiments of the utility model is only for illustrating the technical route and features of the utility model, and its purpose is to enable those skilled in the art to understand the content of the utility model and implement it accordingly, but the utility model is not limited to the above specific implementation methods. All changes or modifications made within the scope of the claims of the utility model should be included in the protection scope of the utility model.
