Description

Technical Field

[0001] This utility model relates to the field of nut-driving technology, and in particular to a double-headed nut-driving device. Background Technology

[0002] In the field of mechanical manufacturing and assembly, the installation of nuts is a crucial step. For a certain product, since the spring is pre-fitted onto the screw, when installing the nut onto the screw, the spring must first be compressed to create enough space for the nut to be smoothly screwed into the screw and reach the designated position.

[0003] However, current assembly primarily relies on manual installation of the nuts. Operators need to use simple tools (such as pliers) to compress the spring while simultaneously screwing the nut into the screw with their other hand. Because both spring compression and nut screwing must be performed simultaneously, and the process is cumbersome, installing a single nut takes a long time, significantly reducing the overall assembly efficiency and making it difficult to meet the demands of large-scale production. Utility Model Content

[0004] Based on this, the present invention provides a double-headed nut-driving device with a simple structure and convenient use. The crank drives the lifting plate and nut bit to fall, and the nut bit compresses the damping spring. Through the coordinated action of the power gear and the driven gear, the electric screwdriver can drive the two nut bits to rotate synchronously, so as to install the nuts onto the screw. This simplifies the operation process, greatly improves the assembly efficiency, and can effectively meet the needs of large-scale production.

[0005] To achieve the objectives of this utility model, the following technical solution is adopted: A double-ended nut-driving device, comprising: The load-bearing assembly includes a base plate, a fixture mounted on the center of the top surface of the base plate, a vertical plate connected to one side of the fixture, and a lifting plate slidably connected to the vertical plate; the lifting plate is located above the fixture; and A nut-driving assembly is installed on the support component; the nut-driving assembly includes a drive gear rotatably connected to the lifting plate, two driven gears meshing with the drive gear, nut bits coaxially connected to each driven gear, magnets installed inside the bottom of each nut bit, an electric screwdriver coaxially connected to the drive gear, a crank rotatably connected to the top of the vertical plate, and a micro switch installed on one side of the vertical plate; the crank is connected to the lifting plate to drive the lifting plate to fall, the micro switch is located below the crank, and the micro switch is electrically connected to the electric screwdriver.

[0006] The aforementioned double-headed nut-driving device has a simple structure and is easy to use. The crank drives the lifting plate and nut bit to fall, and the nut bit compresses the damping spring. Through the coordinated action of the power gear and the driven gear, the electric screwdriver can drive the two nut bits to rotate synchronously, so as to install the nuts onto the screw. This simplifies the operation process, greatly improves the assembly efficiency, and can effectively meet the needs of large-scale production.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0017] Please see Figures 1 to 7 This invention relates to a double-headed nut-driving device, comprising a support assembly 10 and a nut-driving assembly 20 mounted on the support assembly 10. The support assembly 10 is used to clamp a product 30, which includes a product body 31, screws 32 connected to opposite sides of the top of the product body 31, and damping springs 33 respectively sleeved on each screw 32.

[0018] The supporting assembly 10 includes a base plate 11, a fixture 12 installed in the middle of the top surface of the base plate 11, a vertical plate 13 connected to one side of the fixture 12, and a lifting plate 14 slidably connected to the vertical plate 13; the lifting plate 14 is located above the fixture 12. The fixture 12 is used to accommodate the product 30, and the lifting plate 14 is used to connect the nut-setting assembly 20.

[0019] In this embodiment, the supporting assembly 10 further includes a positioning rod 15 installed on the top surface of the base plate 11 and a return spring 16 sleeved on the positioning rod 15; the positioning rod 15 is slidably inserted below the lifting plate 14, and the return spring 16 is clamped between the lifting plate 14 and the base plate 11. Specifically, the bottom end of the lifting plate 14 is provided with a sliding cavity 140, which is used to accommodate the positioning rod 15 to better ensure the linear movement of the lifting plate 14.

[0020] In this embodiment, the length direction of the positioning rod 15 is consistent with the lifting direction of the lifting plate 14.

[0021] like Figure 2 As shown, a guide rod 17 is connected to one side of the lifting plate 14, and the guide rod 17 is used to connect the nut-driving assembly 20.

[0022] The nut-driving assembly 20 includes a power gear 21 rotatably connected to the lifting plate 14, two driven gears 22 meshing with the power gear 21, nut-driving bits 23 coaxially connected to each driven gear 22, magnets 24 installed inside the bottom of each nut-driving bit 23, an electric screwdriver 25 coaxially connected to the power gear 21, a crank 26 rotatably connected to the top of the upright plate 13, and a micro switch 27 installed on one side of the upright plate 13. The crank 26 is connected to the lifting plate 14 to drive it to fall, and the micro switch 27 is located below the crank 26 and electrically connected to the electric screwdriver 25.

[0023] In this embodiment, the nut bit 23 corresponds one-to-one with the screw 32. The nut bit 23 is used to pick up the nut 28 and install it onto the screw 32. The bottom end of the nut bit 23 is provided with a suction chamber 230, which is used to accommodate the magnet 24 and the nut 28. The magnet 24 can be used to attract the nut 28 into the suction chamber 230.

[0024] Specifically, the crank 26 is provided with a slide groove 260, and the guide rod 17 is matched and installed inside the slide groove 260. Rotating the crank 26 can drive the lifting plate 14 to fall. After the crank 26 rotates to a certain angle, it abuts against the micro switch 27, thereby starting the electric screwdriver 25 to work.

[0025] During assembly, crank 26 drives the lifting plate 14 and nut bit 23 to fall, compressing the damping spring 33. When crank 26 abuts against micro switch 27, electric screwdriver 25 starts. Through the coordinated action of drive gear 21 and driven gear 22, electric screwdriver 25 drives the two nut bits 23 to rotate synchronously, thus installing the nut 28 onto the screw 32. Since the electric screwdriver 25 can be set with a torque value, the nut-setting is completed when a certain torque is reached, and electric screwdriver 25 stops working. At this time, crank 26 is released, and under the action of return spring 16, the lifting plate 14 is raised, that is, the entire nut-setting assembly 20 is raised, ready for use in the next operation cycle.

[0026] In this embodiment, two driven gears 22 are spaced apart and rotate in the same direction, which in turn makes the two nut bits 23 rotate in the same direction.

[0027] In this embodiment, the electric screwdriver 25 is connected to the lifting plate 14 via the bracket 250.

[0028] The above-mentioned double-headed nut-driving device has a simple structure and is easy to use. The crank 26 drives the lifting plate 14 and the nut bit 23 to fall. The nut bit 23 compresses the damping spring 33. Through the coordinated action of the power gear 21 and the driven gear 22, the electric screwdriver 25 can drive the two nut bits 23 to rotate synchronously, so as to install the nut 28 onto the screw 32. This simplifies the operation process, greatly improves the assembly efficiency, and can effectively meet the needs of large-scale production.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
