Description

Technical Field

[0001] This invention relates to the field of installation tools in mechanical manufacturing, and in particular to a nut installation tool. Background Technology

[0002] During shipbuilding, stud plates for louvers, manhole covers, and other components require a large number of nuts. During installation, it is necessary to manually sort out the flat washers, elastic washers, and nuts and insert them one by one into the studs. When the plate is inverted, completing these three steps is even more difficult, requiring one hand to hold down the inserted flat washers and elastic washers to prevent them from falling off due to gravity, which seriously restricts installation efficiency. Summary of the Invention

[0003] In view of the above-mentioned problems existing in the prior art, the present invention provides a nut installation tool that can simultaneously engage and pre-tighten the flat plate, spring washer and nut with the seat plate bolt block, which can effectively improve the installation efficiency and is suitable for a large number of bolt installation pre-tightening operations.

[0004] This invention provides a nut installation tool, comprising:

[0005] The device chassis has a nut feeding channel, a spring washer feeding channel, and a flat plate feeding channel for feeding materials.

[0047] This invention provides a nut installation tool, such as... Figures 1 to 15 As shown, it includes:

[0048] The device chassis 1 is provided with a nut feeding channel 13, a spring washer feeding channel 14, and a flat plate feeding channel 15 for feeding materials. All three feeding channels are connected to corresponding conveying hoses. The device chassis 1 is also provided with a through hole for the central shaft 8 and the drive rod 9 to pass through, and a blind hole for the shaft of the driven gear 11 to be installed. Specifically, the nut feeding channel 13, the spring washer feeding channel 14, and the flat plate feeding channel 15 are all provided with internal threads and are threadedly connected to the corresponding nut conveying pipe, spring washer conveying pipe, and flat plate conveying pipe.

[0049] The transmission fixed plate 2 has a nut feeding channel 13 and a spring washer feeding channel 14 corresponding to those on the device chassis 1. It also has an interference fit shaft hole with the central shaft 8, and a gear meshing cavity for the drive gear 10 on the drive rod 9 and the driven gear 11 on the rotating shaft to mesh with the driven gear 11 and the output hexagonal gear 12 located in the nut feeding channel 13. The plate is filled with grease. The thickness of the transmission fixed plate 2 is the same as the thickness of the nut. The output hexagonal gear 12 has a built-in hexagonal wrench cavity. The driven gear 11 can increase the torque and transmit it to the built-in hexagonal wrench cavity, enabling the nut to be rotated and tightened.

[0050] The first isolation fixing plate 3 is used to limit and fix the drive gear 10 and the driven gear 11, and is provided with a shaft hole that is interference fit with the central shaft 8, and a nut feeding channel 13 and a spring washer feeding channel 14 that are corresponding to the nut feeding channel 13 and the spring washer feeding channel 14 on the device chassis 1.

[0051] The spring washer turntable 4 has a spring washer cavity with a thickness that is the same as the maximum thickness of the spring washer in its natural state, ensuring that only one spring washer enters at a time. The spring washer turntable 4 has a shaft hole that is clearance-fitted with the central shaft 8. The spring washer turntable 4 is equipped with a manual push-pull device 16 that can pull it to rotate around the central shaft 8 between 0 degrees and 180 degrees, as well as a flat channel hole.

[0052] The second isolation fixing plate 5 is provided with a flat channel and a first integral channel, as well as a shaft hole that is interference-fitted with the central shaft 8. After the spring washer turntable 4 is pulled and rotated 180 degrees, the spring washer cavity is connected with the nut feeding channel. The second isolation fixing plate 5 has no thickness requirement.

[0053] The flat plate turntable 6 has a flat plate cavity with the same thickness as the flat plate to ensure that only one washer passes through at a time. At the same time, the flat plate turntable 6 also has a shaft hole that is clearance-fitted with the central shaft 8. The flat plate turntable 6 is equipped with a linkage push device 17 that can pull it to rotate around the central shaft 8 between 0 degrees and 90 degrees.

[0054] Fixed plate 7, on which a second integral channel is provided;

[0055] The device chassis 1, the transmission fixed plate 2, the first isolation fixed plate 3, the spring washer turntable 4, the second isolation fixed plate 5, the flat turntable 6, and the fixed plate are connected in series via the central shaft 8 to ensure the stability of the overall structure. The drive rod 9 can transmit the torque output by the drive device to the nut installation tool. The drive rod 9 is connected to the drive gear 10. Different sizes of drive rod 9 can be made according to the actual power tool used. The drive rod 9 can transmit the torque output by the power tool (drive device) to the entire device.

[0056] During operation, the manual push-pull device 16 pulls the spring washer turntable 4 to rotate around the central axis 8 to 90 degrees. While pulling the spring washer turntable 4 to rotate around the central axis 8 to 180 degrees, the linkage push device 17 drives the flat plate turntable 6 to rotate around the central axis 8 to 90 degrees, so that the nut, spring washer and flat plate to be installed are on the same axis. The screw to be connected is inserted through the second integral channel on the fixed plate 7, and then the drive rod 9 is used to complete the simultaneous installation of the nut, spring washer and flat plate.

[0057] In this embodiment, the nut feeding channel 13, the spring washer feeding channel 14, and the flat plate feeding channel 15 are respectively connected to the feeding and supply ends of the nuts, spring washers, and flat plates through the nut feeding hose 22, the spring washer feeding hose 23, and the flat plate feeding hose 24.

[0058] In some embodiments of the present invention, the conveying supply end includes:

[0059] Backpack 20 is equipped with a nut sorting and pushing device 18 for sorting nuts, a spring washer sorting and pushing device 19 for sorting spring washers, and a flat plate sorting and pushing device 20 for sorting flat plates. The sorting and pushing devices can automatically push the corresponding materials into the conveying hose in a fixed state. Backpack 20 can be configured as a 3-compartment backpack, and each compartment can hold nuts, spring washers, and flat plates respectively. Backpack 20 can be used to store a large number of materials.

[0060] In this embodiment, the backpack 20 is also equipped with a battery 25 for powering the sorting and propulsion device.

[0061] In some embodiments of the present invention, the conveying supply end includes:

[0062] Nut push tube 28, spring washer push tube 27, and flat plate push tube 26 are respectively connected to the nut feeding channel 13, the spring washer feeding channel 14, and the flat plate feeding channel 15 and can realize immediate feeding. Each of the nut push tube 28, spring washer push tube 27, and flat plate push tube 26 is provided with an elastic pusher. They are used for the installation of a small number of nuts, can be directly connected to the device, and can realize immediate feeding.

[0063] In some embodiments of the present invention, the drive rod 9 can be equipped with an adapter to connect to drive devices of different sizes. As an example, the drive device is an electric wrench.

[0064] To facilitate understanding of the above technical solutions, specific examples are provided below:

[0065] First, the device chassis 1, transmission fixed plate 2, first isolation fixed plate 3, drive rod 9, drive gear 10, driven gear 11, and output plum blossom gear 12 are assembled into a whole, which is the main power unit and conveying channel of this device.

[0066] Furthermore, the spring washer turntable 4 is positioned above the first isolation fixing plate 3, with a range limit of 0 to 180 degrees. The spring washer cavity is aligned with the first isolation fixing plate 3. A flat cavity is set at a position where the line connecting the spring washer and the shaft hole is 180 degrees apart. When the manual push-pull device 16 pulls the spring washer turntable 4 to rotate 180 degrees at the zero position, the flat channel hole of the spring washer turntable 4 opens with the flat channel on the second isolation fixing plate 5.

[0067] Furthermore, under the propulsion action, the flat plate turnstable 6 is installed above the second isolation fixing plate 5. The flat plate turnstable 6 is set with a range limit from 0 degrees to 90 degrees. When 0 degrees is taken as the reference in the range of 0 degrees to 180 degrees of rotation of the spring washer turnstable 4, the corresponding range limit of the flat plate turnstable 6 is 90 degrees to 180 degrees. Specifically, it can be pulled by the linkage push device 17 to rotate 90 degrees. The linkage push device 17 is linked with the manual push-pull device 16. When the manual push-pull device 16 pulls the spring washer turnstable 4 to rotate to 90 degrees, the linkage push device 17 pulls the flat plate turnstable 6 to start rotating together with the spring washer turnstable 4, and finally rotates to the position corresponding to 180 degrees.

[0068] At this point, all channels of the nut installation tool are connected, and the nut, spring washer, and flat plate are on the same axis.

[0069] At this point, the second integral channel (the only channel) on the fixing plate 7 at the top of the nut installation tool can be inserted into the screw to be connected (which can be a base plate screw).

[0070] Furthermore, the power tool connected to the drive rod 9 is activated, driving the drive gear 10 so that the nut inside the cavity rotates clockwise and is pre-tightened with the base plate screw.

[0071] After a single installation is completed, the manual push-pull device 16 is pulled back to the zero position, the spring washer turntable 4 channel is opened to complete the spring washer replenishment, and during the process, the linkage push device 17 is driven back to the 90° zero position, thus completing one installation cycle.

[0072] Depending on the number of units to be installed, choose either the backpack type 20 or the propulsion tube.

[0073] As can be seen from the above technical solution, the nut installation tool cleverly places the flat plate, elastic washer, and nut on the same axis and in the same channel through a multi-layer stacking and rotation scheme, enabling the seat plate bolt to smoothly pass through the two washers and engage with the nut; through the built-in gear transmission, it can be quickly connected to the power tool via the drive rod 9, and the rotational power of the power tool drives the output box gear 12 through the driven gear 11, realizing the pre-tightening or untightening of the nut in the cavity (internal hexagonal socket gear) of the box wrench, and the pre-tightening force can be set by the torque of the power tool; furthermore, through the backpack storage device (backpack 20) ​​and the internal equipment's sorting and pushing device (automatic rolling and pushing device), the flat plate, elastic washer, and nut are respectively transmitted to the tool's inner cavity through pipes, completing one installation and spring After the washer turntable 4 and the flat plate turntable 6 return to the 0 position, the elastic washer and flat plate are automatically replenished, realizing automatic feeding. Both the transmission hose and the rigid pipe are within the scope of protection of this patent. In addition, the thickness of the spring washer turntable 4 and the flat plate turntable 6 are the same as the thickness of the elastic washer and the flat plate, respectively, to ensure that only one elastic washer and one flat plate can be accommodated at a time, and to ensure that there is no jamming after each rotation. The elastic washer turntable is rotated 180 degrees by the manual push-pull device 16, and the flat plate turntable 6 is rotated 90 degrees by the linkage push device 17. After pulling back, the spring washer turntable 4 and the flat plate turntable 6 are returned to the zero position at the same time. This invention is manual, but the protection point is not limited to manual. The same principle of electric operation is also within the scope of protection of this patent. The existing shape is cylindrical. Other irregular shapes that adopt the same rotation and overlap principle are also within the scope of protection of this patent.

[0074] In addition, the aforementioned nut installation tool simplifies the tedious installation process, especially when a large number of nuts are pre-tightened, enabling rapid installation.

[0075] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
