Description

Technical Field

[0001] The utility model relates to the technical field of screw installation, in particular to a device for driving a screw to rotate. Background Art

[0002] During the processing of parts, some parts need to have screws installed on their surfaces. Currently, most screws need to be installed manually. After the parts are fixed, they need to be installed again with an electric screwdriver. In the assembly line working environment, this operation mode has high labor intensity and cannot meet the needs of automated production. Therefore, we propose a screw-driving rotation device to solve the above problems. Utility Model Content

L-shaped limit rods are slidably installed on the two first guide rods, one end of the two limit rods is connected to the material trough, and the outer ends of the two limit rods are fitted together, and the bottom ends of the two limit rods are provided with first springs.

[0007] In a preferred embodiment of the utility model, a positioning mold is fixed on the slide, and a contactor compatible with the position sensor is provided on the slide. When the slide moves to the bottom of the driving mechanism, the slide stops through the cooperation between the position sensor and the contactor, thereby facilitating the installation of screws on the parts.

[0008] In a preferred embodiment of the utility model, the limit rod is located directly below the driving mechanism, and a limit groove is provided on the inner side of the limit rod, and the limit groove limits the slipped screw so that the screw is located directly above the mounting hole on the component.

[0009] In a preferred embodiment of the utility model, the two support columns and the material trough are deflected outward by 2° to 5° along the vertical line direction of the lower end. By setting a certain inclination angle, the two limit rods are separated when they descend to the bottom, thereby disengaging the installed screws from the limit rods.

[0010] In a preferred embodiment of the utility model, the driving mechanism includes a base plate fixed on the cross beam, a push rod motor is fixed on the base plate, a mounting plate is fixed to the telescopic end of the push rod motor, the mounting plate is slidably connected to the base plate, and two second guide rods are vertically fixed on the mounting plate, the two second guide rods are slidably connected to the same mounting seat, a second spring is directly fixed to the top of the mounting seat and the second guide rod, and an electric screwdriver is fixed on the mounting seat, the electric screwdriver is driven to descend by the push rod motor to rotate the screw, and during the descent process, the electric screwdriver is buffered by the second spring during operation to avoid damage to components due to continued rigid extrusion when the screw cannot rotate.

[0011] In a preferred embodiment of the utility model, a limiting boss is provided at the bottom end of the electric screwdriver. When the electric screwdriver descends to rotate the screw on the limiting rod, the screw on the material trough is blocked by the limiting boss to prevent it from slipping.

The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0019] like Figure 1-3 A screw-driving rotating device shown in the figure comprises a support frame 1 and a conveying track 2 arranged on the support frame 1, the conveying track 2 is connected to an external conveying line, a slide 3 for fixing parts is arranged on the conveying track 2, a positioning mold is fixed on the slide 3, and the parts to be installed with screws are fixed by the positioning mold;

[0020] Among them, position sensors 5 and vibrating plate feeders 4 are respectively arranged on both sides of the conveying track 2, and a contactor adapted to the position sensor 5 is arranged on the slide 3. When the slide 3 moves to the bottom of the driving mechanism 7, the slide 3 stops through the cooperation between the position sensor 5 and the contactor, so as to facilitate the installation of screws on the parts;

[0021] A material trough 41 for discharging materials is provided on one side of the vibrating plate feeder 4. The material trough 41 is inclined toward the slide seat 3, and support columns 42 are fixed on both sides of the bottom end of the material trough 41. The two support columns 42 are inclined outward, and the angle between the two support columns 42 and the material trough 41 is 2° to 5°. By setting a certain inclination angle, the two limit rods 43 are separated when they drop to the bottom, thereby disengaging the installed screws from the limit rods 43, and the first guide rods are fixed on the two support columns 42. 44, an L-shaped limit rod 43 is slidably mounted on the two first guide rods 44, a through hole matching the first guide rod 44 is opened on the limit rod 43, the first guide rod 44 is inserted in the through hole, and a limit block is arranged at the top of the first guide rod 44, one end of the two limit rods 43 is butted with the material trough 41, and the upper surface thereof is flush, and the bottom ends of the two limit rods 43 are both provided with a first spring 45, and when the first spring 45 is in a natural state, the outer ends of the two limit rods 43 are in contact with each other;

[0022] Furthermore, the limiting rod 43 is located directly below the driving mechanism 7, and a limiting groove 46 is provided on the inner side of the limiting rod 43, and the limiting groove 46 limits the slipped screw so that the screw is located directly above the mounting hole on the component;

[0023] Secondly, a crossbeam 6 is arranged above the conveying track 2, and a driving mechanism 7 for rotating the screw is installed on the crossbeam 6. The driving mechanism 7 includes a base plate 71 fixed on the crossbeam 6, a push rod motor 72 is fixed on the base plate 71, and a mounting plate 73 is fixed to the telescopic end of the push rod motor 72. The mounting plate 73 is slidably connected to the base plate 71, and two second guide rods 74 are vertically fixed on the mounting plate 73, and the two second guide rods 74 are slidably connected to the same mounting seat 75. A second spring 76 is directly fixed to the top of the mounting seat 75 and the second guide rod 74, and an electric screwdriver 77 is fixed on the mounting seat 75. The electric screwdriver 77 is driven to descend by the push rod motor 72 to rotate the screw. At the same time, during the descent process, the electric screwdriver 77 in the running process is buffered by the second spring 76 to avoid damage to parts due to continued rigid extrusion when the screw cannot be rotated.

[0024] Furthermore, a limiting boss 78 is provided at the bottom end of the electric screwdriver 77. When the electric screwdriver 77 descends to rotate the screw on the limiting rod 43, the screw on the material trough 41 is blocked by the limiting boss 78 to prevent it from slipping.

[0025] In this embodiment, after the parts to be installed with screws are fixed on the slide 3, they are transported to the bottom of the driving mechanism 7 through the conveying track 2. At the same time, the screws are transported by the vibrating plate feeder 4, and the screws slide along the material trough 41 to the limit rod 43, and are located between the driving mechanism 7 and the parts;

[0026] When the slide 3 stops, the electric screwdriver 77 and the push rod motor 72 are started, and the mounting plate 73 is driven to descend by the push rod motor 72, and the electric screwdriver 77 is also driven to descend, and the electric screwdriver 77 pushes the screw to descend and rotate into the component. When the screw descends, the limit rod 43 descends on the first guide rod 44. When the limit rod 43 descends to the bottom, the two limit rods 43 separate, so that the screw is disengaged from the limit rod 43. After the electric screwdriver 77 is reset, the limit rod 43 is driven to reset by the first spring 45, so that the screw continues to slide from the material trough 41 to the limit rod 43 to continue the next installation.
