Detailed Implementation
[0050] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of the present invention and are used together with the invention to illustrate the principles of the invention.
[0051] Example 1
[0052] This embodiment provides a nut assembly method, see [link / reference] Figure 1 This method is implemented using an installation device, and specifically includes:
[0053] Step 1: Prepare nuts of different sizes according to the installation requirements of the equipment;
[0054] Step 2: Sort the nuts according to the installation area and nut size;
[0055] Step 3: According to the order in Step 2, fix the nut onto the mounting device;
[0056] Step four: Position the installation device at the installation point of the nut to be installed on the instrument, activate the installation device, and assemble the nut onto the instrument.
[0057] The nut assembly method provided by this invention involves adsorbing the nut to be installed onto a first gear during use; extending the working end into the confined space of the nut; activating the drive device, which drives the transmission mechanism to rotate; rotating the first gear; and rotating the nut along with the first gear, thus installing the nut onto the device within the confined space. This embodiment is assembled from simple components, has a simple structure, is easy to operate, and has low manufacturing costs. It can achieve a constant torque tightening of the nut without the need for complex specialized equipment.
[0058] In this embodiment, the specific operation of step two is as follows: within the same installation area, multiple nuts to be installed are sorted according to their size from largest to smallest.
[0059] In this embodiment, in step three, the nut is attached to the mounting device.
[0060] In this embodiment, in step three, when the size of the nut cannot be attracted to the mounting device, the component of the mounting device that attracts the nut is replaced.
[0061] The components on the mounting device that adsorb nuts have different adsorption sizes. When a component cannot adsorb the nut to be installed, it needs to be replaced.
[0062] In this embodiment, between step three and step four, a set force value is further included for the mounting device to assemble the nut.
[0063] In this embodiment, the mounting device includes a brushless DC drive device, and the torque value of the brushless DC drive device is set to determine the constant force value for assembling the nut.
[0064] In this embodiment, the installation device includes a working end, and in step four, the working end extends into the installation point of the nut to be installed on the instrument.
[0065] In this embodiment, the working end is made of antistatic material.
[0066] In this embodiment, the working end is provided with a fixing point for fixing the nut.
[0067] In this embodiment, an adsorption element is provided at the fixed site. The adsorption element is a strong magnet.

The working end can extend into the confined working conditions. Start the installation device and assemble the nuts onto the instrument device, ensuring that different nuts have the same constant force value, thereby ensuring the overall installation quality of the instrument.
[0069] Example 2
[0070] This embodiment provides an installation device for implementing a nut assembly method. See [link to relevant documentation]. Figure 2 and Figure 3 As shown, the installation device includes a first plate 1, a driving device 2, and a transmission mechanism 3; the first plate 1 includes a non-working end and a working end that can extend into narrow spaces; the transmission mechanism 3 is fixed on the working end and rotates under the drive of the driving device 2; the output end of the transmission mechanism 3 is a first gear 31, which is used to attract the nut to be installed.
[0071] like Figure 3 As shown, a magnetic 311 is bonded to the upper surface of the first gear 31, and the thickness of the magnetic 311 is preferably 1 mm.
[0072] The nut assembly method described in this embodiment involves adsorbing the nut to be installed onto the first gear 31; inserting the working end into the confined space of the nut; activating the drive device 2; and driving the transmission mechanism 3 to rotate, thereby rotating the first gear 31. The nut rotates with the first gear 31, thus installing it onto the device within the confined space. This embodiment is assembled from simple components, featuring a simple structure, convenient operation, and low manufacturing cost. It can achieve a constant torque tightening of the nut without the aid of complex specialized equipment.
[0073] The self-priming constant torque device in this embodiment also includes a second plate 4, which is disposed opposite to the first plate 1; the transmission mechanism 3 is disposed between the second plate 4 and the first plate 1.
[0074] The second plate 4 is fixedly connected to the first plate 1 by a fastener, and the transmission mechanism 3 is disposed between the second plate 4 and the first plate 1. The distance between the second plate 4 and the first plate 1 is sufficient to allow the transmission mechanism 3 to rotate.
[0075] In this embodiment, a first through hole 41 is provided on the second plate 4, and the first through hole 41 matches the first gear 31.
[0076] The nut to be installed is mounted onto the first gear 31 through the first through hole 41. During operation, the nut is placed onto the first gear 31 through the first through hole 41, allowing for installation in confined spaces, making the operation simple and quick.
[0077] In this embodiment, the size of the first through hole 41 is larger than the size of the nut.
[0078] In this embodiment, a third plate 5 is also included, which is disposed between the first plate 1 and the second plate 4.
[0079] The thickness of the third plate 5 is equal to the thickness of the transmission mechanism 3, or the thickness of the third plate 5 is slightly larger than the thickness of the transmission mechanism 3, to meet the rotation requirements of the transmission mechanism 3.
[0080] In this embodiment, the transmission mechanism 3 further includes a second gear 32, a third gear 33, and a fourth gear 34.
[0081] The second gear 32 is disposed at the output end of the drive device 2. The drive device 2 drives the second gear 32 to rotate, and the second gear 32 drives the third gear 33 to rotate. The third gear 33 meshes with the first gear 31, and the third gear 33 drives the first gear 31 to rotate. The first gear 31 drives the nut to be installed to rotate, thereby realizing the installation of the nut. The second gear 32, the third gear 33 and the fourth gear 34 are fixed between the first plate 1 and the second plate 4. The first gear 31 is engaged between the third gear 33 and the fourth gear 34. There are two fourth gears 34. The two fourth gears 34 and the third gear 33 form a triangular fixing area, which firmly fixes the first gear 31 between the fourth gear 34 and the third gear 33, and the fixing relationship is stable.
[0082] Example 3
[0083] This embodiment provides an installation device for implementing a nut assembly method. See [link to relevant documentation]. Figures 4 to 7 Based on Embodiment 2, it further includes a mounting kit 7 disposed on the second plate 4; the mounting kit 7 includes a mounting box 71, a pushing component 72, and a rotating part 73; to better demonstrate the internal mechanism of the mounting kit 7, Figure 3 The mounting box 71 does not have a top surface. Figure 4 The mounting box shown has a top cover.
[0084] The mounting box 71 is a cuboid structure with one open end. The mounting box 71 has a space for accommodating nuts, and multiple nuts are linearly arranged within this space. A pushing component 72 is disposed at one end of the cavity opposite to the opening. The pushing component 72 includes a first damping element 721 and an actuating plate 722. One end of the first damping element 721 is disposed on the end face of the cavity opposite to the opening, and the other end is disposed on one end face of the actuating plate 722. The other end face of the actuating plate 722 abuts against the nuts disposed in the cavity. The mounting box 71 serves as a storage device for spare nuts, and its size can be selected according to actual usage needs. The nuts can be linearly arranged within the cavity. When a spare nut is discharged from the opening, the first damping element 721 pushes the actuating plate 722, which then pushes the candidate nuts forward to fill the gap. As long as there are spare nuts in the mounting box, i.e., at the opening of the mounting box 71, there is a spare nut that can be used at any time.
[0085] like Figure 6 As shown, Figure 6 This is a schematic diagram of the inverted structure of the rotating part 73. The rotating part 73 includes a second rotating shaft 731, a rotating wheel 732, a first ring body 733, a second ring body 734, a second damping element 735, a wedge-shaped connecting block 736, and a rotating rod 737, as shown. Figure 5 and Figure 6 As shown, the second rotating shaft 731 is vertically arranged on the lower end surface inside the mounting box 71. The rotating wheel 732 is rotatably arranged, and the second rotating shaft 731 rotates with the rotating wheel 732. The first ring body 733 is sleeved on the second rotating shaft 731, and the first ring body 733 is located above the rotating wheel 732. The first ring body 733 rotates with the second rotating shaft 731. A sliding track is provided on the upper end surface of the first ring body 733, and the sliding track is arranged along the radial direction of the first ring body 733. The second damping element 735 is provided with... The second damping element 735 is placed inside the sliding track. One end of the second damping element 735 is disposed on the second rotating shaft 731, and the other end of the second damping element 735 is disposed on the wedge-shaped connecting block 736. The second ring body 734 is sleeved on the first ring body 733, and the inner wall of the second ring body 734 is a wedge-shaped groove that matches the wedge-shaped connecting block 736. The rotating rod 737 is disposed on the second ring body 734, and two adjacent rotating rods 737 are arranged at a 90° angle. The angle between the two rotating rods 737 is the space for setting the nut clamping space.
[0086] When the first ring body 733 rotates forward, the second damping element is in an uncompressed state. The wedge-shaped connecting block 736 is matched and engaged in the wedge-shaped groove. During forward rotation, the wedge-shaped connecting block 736 pushes against the wall of the wedge-shaped groove, and the wedge-shaped connecting block 736 drives the second ring body 734 to rotate. When the mounting box moves towards the working end, the first ring body 733 rotates forward, and the first ring body 733 can drive the second ring body 734 to rotate. The rotating rod 737 moves the nut inside the mounting box while the second ring body 734 rotates. When the first ring body 733 rotates in the reverse direction, the... The wedge-shaped connecting block 736 cannot be locked in the wedge-shaped groove. The inclined surface of the wedge-shaped connecting block 736 and the inclined surface of the wedge-shaped groove are inclined surfaces that can move relative to each other. The wedge-shaped connecting block 736 slides along the groove wall of the wedge-shaped groove. The wedge-shaped connecting block 736 cannot drive the second ring body 734 to rotate, that is, the second ring body 734 cannot rotate in the opposite direction with the first ring body 733. When the mounting box is away from the working end, the first ring body 733 rotates in the opposite direction under the drive of the second rotating shaft 731. The first ring cannot drive the second ring body to rotate, the rotating rod 737 does not rotate, and the position of the nut in the mounting box remains unchanged. By controlling the movement direction of the mounting box, the effect of whether to equip the nut in the mounting box to the working end of the first plate is achieved.
[0087] In this embodiment, the second ring 734 is provided with a total of 4 rotating rods 737, which together form 4 nut clamping spaces. When not rotating, the space that clamps the nut is designated as the first space, and clockwise, they are designated as the second, third, and fourth spaces. When the first ring 733 and the second ring 734 rotate synchronously, the second ring 734 drives the rotating rods 737 to rotate. The nut clamped between the two rotating rods 737 is discharged from the opening of the mounting box 71 in accordance with the rotation of the rotating rods 737. That is, the first space rotates to the fourth space, and the original second space becomes the first space. At the same time, the actuating plate pushes the nut in the mounting box to move towards the opening position, so that the two rotating rods 737 corresponding to the original second space rotate and clamp the nut pushed up, thus completing the movement of the nut position.
[0088] A slider is provided on the lower end of the mounting box 71.
[0089] The second plate 4 has a sliding track 42 at the position corresponding to the slider;
[0090] The second plate 4 is provided with a threaded rod 43, which is located near the working end; when the rotating wheel 732 reciprocates on the sliding track 42 with the mounting box 71, the threaded rod 43 is located on the movement path of the rotating wheel 732; the rotating wheel 732 is provided with a first thread, and the threaded rod 43 is provided with a second thread that matches the first thread, and the threaded rod 43 meshes with the rotating wheel 732.
[0091] A baffle plate 711 is provided at the opening of the mounting box 71. The baffle plate 711 is a plate that is thinner at the top and thicker at the bottom. The lower end of the baffle plate 711 is hinged to the lower end face of the mounting box 71 via a first rotating shaft 712. A fifth gear 713 is provided at one end of the first rotating shaft 712. There is a certain gap between the lower end face of the fifth gear 713 and the upper end of the second plate. A toothed strip 44 is provided on the upper end face of the second plate 4. The toothed strip 44 matches the fifth gear 713. When the fifth gear 713 is not engaged with the toothed strip 44, the baffle plate 711 is in a vertical position under the self-locking state of the rotating shaft. In the upright position, the baffle 711 can prevent the nut from sliding out of the mounting box 71; when the mounting box 71 moves to the position of the toothed rack 44, the fifth gear 713 meshes with the toothed rack and rotates, the fifth gear 713 drives the first rotating shaft 712 to rotate, the first rotating shaft 712 drives the baffle 711 to rotate, the baffle 711 changes from the position of vertically blocking the nut to the horizontal position, and the baffle 711 in the horizontal position has a slope, and the height of the baffle 711 in the horizontal position is lower than the height of the lower end face of the mounting box 71, so the nut can slide out along the slope of the baffle 711. As the mounting box moves toward the working end, the baffle plate 711 is vertically positioned to prevent the nut from sliding out of the mounting box 71. The toothed strip 44 is positioned on the second plate near the first through hole 41. When the mounting box moves to the vicinity of the working end, the toothed strip 44 and the fifth gear 713 work together to open the baffle plate, ensuring that the nut slides out of the mounting box under the push of the rotating rod 737.
[0092] In actual operation, 20-40 or more nuts of the same specification often need to be installed on the same device. After each nut is installed, another nut needs to be manually removed and placed on the first gear 31, which affects work efficiency. During the nut installation process, the installation kit 7 can automatically assemble the nut onto the first gear 31, reducing manual operation and improving labor efficiency.
[0093] Multiple nuts are arranged sequentially in the mounting box 71, with one end of each nut resting on the actuating plate 722 and the other end of each nut located at the opening of the mounting box 71. The rotating part 73 is matched with the nut located at the opening, and the included angle formed by the two rotating rods 737 is matched to clamp the nut.
[0094] After a nut is installed, the operator pushes the mounting box 71 to move in the sliding track 42. During the sliding process, the baffle plate 711 is in a vertical position to prevent the nut from sliding out of the mounting box 71. When the mounting box 71 moves to the position of the toothed rack 44, the fifth gear meshes with the toothed rack 44. The fifth gear drives the first rotating shaft 712 to rotate, causing the baffle plate 711 to change from a vertical position to a horizontal position. In the horizontal position, the baffle plate 711 is not higher than the upper end surface of the mounting box, and the baffle plate 711 does not block the nut from being moved out of the mounting box. The second thread on the threaded rod 43 meshes with the first thread on the rotating wheel 732. The threaded rod 43 drives the rotating wheel 732 to rotate forward. The rotating wheel 732 sequentially drives the second rotating shaft 731, the first ring body 733, the second ring body 734, and the rotating rod 737 to rotate. As the rotating rod 737 rotates, the nut clamped between the two rotating rods 737 is pushed out of the mounting box. Under the action of the slope of the baffle plate 711, the slope of the side wall of the first through hole 41, and the magnetic attraction of the first gear 31, it moves to the first through hole 41 and is attracted to the first gear 31, completing the assembly of the next nut.
[0095] After the nut assembly is completed, the mounting box 71 is pushed back to the non-working end. During the push-back process, the fifth gear 713 re-engages with the toothed rack 44, causing the toothed rack 44 to drive the fifth gear 713 to rotate in the opposite direction. The fifth gear 713 then drives the first rotating shaft to rotate in the opposite direction, causing the baffle plate 711 to rotate from a horizontal position to a vertical position, continuing to prevent the nut from being removed from the mounting box 71. Simultaneously, the threaded rod 43 drives the rotating wheel 732 to rotate in the opposite direction, which in turn drives the first ring body 733 to rotate in the opposite direction. The wedge-shaped connecting block 736 on the first ring body 733 cannot be locked in the wedge groove. Under the pulling force of the telescopic deformation of the second damping element 735, the wedge-shaped connecting block 736 slides along the inside of the wedge groove, meaning the second ring body 734 cannot rotate with the first ring body 733. The rotating rod 737 does not rotate, and the nut in the mounting box 71 remains in its original position. This prepares for the assembly of the next nut.
[0096] Example 4
[0097] This embodiment provides an installation device for implementing the nut assembly method described above. See [link to relevant documentation]. Figure 8 and Figure 9Based on its second embodiment, a bearing 8 and a bushing 9 are arranged from top to bottom at the output end of the drive device 2; the bushing 9 rotates coaxially with the output end 21. The bearing 8 includes a first inner wall, a first ball, and a first outer wall, and the first groove 81 is formed on the first outer wall; in the mounting device described in this embodiment, a second through hole is formed on the first plate 1 at a position corresponding to the second gear 32, the bearing 8 is disposed in the second through hole, the outer wall of the bearing 8 rotates synchronously with the second gear, the inner wall of the bearing 8 is disposed in the second through hole, and the second through hole also includes a mating through hole that matches the connecting block.
[0098] In use, the bearing is fixed on the second through hole, and the output end passes through the bearing, so that the mating through hole corresponds to the connecting block. The connecting block passes through the mating through hole and is inserted into the first groove 81. When the drive device 2 starts working, the output end 21 rotates, which drives the bushing 9 to rotate. The bushing 9 drives the connecting block 91 to rotate, which drives the first outer wall of the bearing 8 to rotate. The rotation of the first outer wall drives the second gear 32 to rotate, and the transmission mechanism 3 starts working, causing the first gear 31 to rotate, and finally completing the installation of the nut.
[0099] The installation device described in this embodiment includes multiple first plates 1, each of which is equipped with a transmission mechanism 3. The first gears 31 on different first plates can attract nuts of different sizes. During use, if the size of the nut that the currently used first gear 31 can attract is insufficient for the current installation requirements, the first plate 1 can be replaced. Along the axial direction of the output end 21, the currently used first plate 1 is pulled out, and a new first plate 1 that meets the usage requirements is selected. Following the direction corresponding to the mating through hole and the connecting block, a new first plate 1 is inserted into the output end 21, completing the installation process of the new first plate 1.
