Description

Technical Field

[0001] This utility model relates to the field of mechanical assembly technology, specifically to a nut insertion clamp. Background Technology

[0002] In consumer electronics, automotive parts, and smart home industries, bracket-type components such as mobile phone frame brackets, automotive interior brackets, and home appliance structural brackets often require the assembly of nuts to enable detachable connections to subsequent components. Currently, the assembly process of nuts and brackets mainly relies on traditional simple tooling, which suffers from low positioning accuracy, poor assembly efficiency, and low product yield, making it difficult to meet the needs of precision manufacturing.

[0003] Traditional simple tooling is used to assist assembly, but this type of tooling has obvious defects: First, the positioning structure is simple, mostly limited by a single pin or cavity, which cannot be adapted to the complex shape of the bracket. After the bracket is placed, it is easy to shift laterally, resulting in misalignment between the nut and the hole. Second, it lacks a reliable fixing mechanism. The tooling does not have an adsorption or clamping structure. The pressure when the nut is inserted can easily cause the bracket to deform or shift. Especially for thin-walled plastic brackets, problems such as "bracket dent" and "tilted insertion of nut" are likely to occur. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a nut insertion fixture that can accurately position nuts onto a bracket, thereby greatly improving assembly efficiency.

[0005] The objective of this utility model is achieved through the following solution: This utility model discloses a nut implantation clamp for installing a nut on a bracket, including a base and a cover plate. The base is provided with a positioning groove for placing the bracket. The cover plate is disposed on the bracket and the base and covers the positioning groove. The base is provided with a bionic positioning post for positioning the bracket and the cover plate. The cover plate is provided with a through hole to avoid the nut. The nut passes through the through hole and is installed on the bracket.

[0006] Furthermore, the base is provided with an air suction device for fixing the bracket in the positioning groove to prevent the bracket from shifting.

[0007] Furthermore, the suction device has a suction cup at one end that contacts the bracket, and a suction hole is provided in the middle of the suction cup. The bracket is adsorbed onto the suction cup by suctioning air through the suction hole.

[0008] Furthermore, the cover plate is provided with a fixing post facing downwards, and the base is provided with a fixing sleeve corresponding to the fixing post. Both the fixing post and the fixing sleeve are arranged to avoid the bracket.

[0009] Furthermore, the base is provided with a limiting post for confining the bracket within the positioning groove.

[0010] Furthermore, the limiting post is provided with a first guide slope, which is used to guide the bracket into the positioning groove.

[0011] Furthermore, the base is provided with a stop post, which is located in the area where the nut is installed on the bracket, and the stop post is used to prevent the nut from excessively penetrating the bracket.

[0012] Furthermore, the bracket has a preset hole corresponding to the through hole, and the nut is installed in the preset hole.

[0013] Furthermore, the pre-set hole is provided with grooves spaced around its perimeter, which are used to engage with the anti-slip texture on the outer periphery of the nut.

[0014] Furthermore, the upper end of the biomimetic positioning column is provided with a second guide slope, which is used to guide the bracket into the positioning groove.

[0015] The advantages of this invention are that the coordinated design of the positioning groove and the bionic positioning column on the base not only restricts the lateral displacement of the bracket and enables rapid initial positioning, but also uses the bionic positioning column to simultaneously and accurately position the bracket and the cover plate, eliminating the cumulative error of traditional separate positioning. The cover plate covering the positioning groove not only restricts the vertical displacement of the bracket, effectively preventing the thin-walled plastic bracket from deforming due to the pressure of the impact pin and the tilting of the nut during insertion, but also protects the non-processed areas of the bracket, reduces the adhesion of debris and surface scratches, and lowers the appearance defect rate. The clearance through hole on the cover plate can guide the vertical insertion of the nut, preventing insertion deviation and poor engagement, and at the same time serves as a visual marker to avoid omissions or misinstallation, improving the operational error tolerance rate.

[0025] Please see Figures 1 to 5This utility model discloses a nut insertion clamp for installing a nut on a bracket, including a base 10 and a cover plate 20. The base 10 has a positioning groove 11 for placing the bracket 30. The cover plate 20 is disposed on the bracket 30 and the base 10 and covers the positioning groove 11. The base 10 has a bionic positioning post 12 for positioning the bracket 30 and the cover plate 20. The cover plate 20 has a through hole 21 to avoid the nut. The nut passes through the through hole 21 and is installed on the bracket 30. The bracket 30 to be assembled is placed into the positioning groove 11 of the base 10. The positioning groove 11 quickly restricts the lateral displacement of the bracket 30 by adapting to the contour, completing the initial positioning. At the same time, the bionic positioning post 12 on the base 10 is inserted into the bracket 30 to further restrict the rotation and slight displacement of the bracket 30, ensuring that the nut mounting hole on the bracket 30 is in the preset assembly position. Cover the bracket 30 and base 10 with the cover plate 20, so that the cover plate 20 completely covers the positioning groove 11. At this time, the bionic positioning post 12 is inserted into the bionic positioning groove 23 of the cover plate 20. Guided by the bionic positioning post 12, the cover plate 20 and the base 10 are precisely aligned, so that the through hole 21 of the cover plate 20 corresponds one-to-one with the nut mounting hole of the bracket 30. The nut is fed to the through hole 21 of the cover plate 20 by manual or automated feeding device and aligned with the through hole. The implantation tool, such as the thermoforming pin, applies downward force along the through hole 21 to push the nut through the through hole 21. The through hole 21 is constrained by its inner wall, guiding the nut to enter the mounting hole of the bracket 30 in a vertical posture to avoid tilting.

[0026] Please see Figure 2 and Figure 3 The base 10 is equipped with a suction device to fix the bracket 30 in the positioning groove 11 and prevent the bracket 30 from shifting. When the suction device is working, an external air source provides gas power into the air passage through the air source interface, creating a negative pressure in the air passage, which in turn generates suction at the suction hole. When the bracket 30 is placed in the positioning groove 11, the suction force of the suction hole firmly adheres the bracket 30 to the positioning groove 11, achieving a firm fixation of the bracket 30. The end of the suction device that contacts the bracket 30 is equipped with a suction cup 13, and the suction cup 13 has a suction hole 131 in the middle. By sucking air through the suction hole 131, the bracket 30 is adhered to the suction cup 13. The lower surface of the bracket 30 is completely in contact with the suction surface of the suction cup 13 in the positioning groove 11. When the external suction device is activated, negative pressure is transmitted through the air passage of the base 10 to the suction hole 131 in the middle of the suction cup 13. The suction hole 131 quickly removes the air between the suction cup 13 and the bracket 30, forming a sealed negative pressure chamber. Under the action of negative pressure, the soft silicone suction cup 13 deforms slightly, tightly adhering to the surface of the bracket 30, generating a stable suction force, firmly adhering the bracket 30 to the suction cup 13, completely restricting the slight lateral displacement and slight vertical tilting of the bracket 30.

[0027] Please see Figure 4The cover plate 20 has a downwardly mounted fixing post 22, and the base 10 has a corresponding fixing sleeve 14 embedded in the fixing post 22. Both the fixing post 22 and the fixing sleeve 14 are positioned to avoid the bracket 30. The fixing post 22 on the lower surface of the cover plate 20 is simultaneously inserted into the corresponding fixing sleeve 14 on the base 10. The gap fit between the fixing post 22 and the fixing sleeve 14 achieves precise fixation between the cover plate 20 and the base 10, preventing the cover plate 20 from shifting due to vibration during implantation.

[0028] Please see Figure 2 The base 10 is provided with a limiting post 15, which is used to confine the bracket 30 within the positioning groove 11. After the bracket 30 is fully placed into the positioning groove 11, the limiting post 15 contacts the edge of the bracket 30, confining the bracket 30 within a preset area in the positioning groove 11, thus initially limiting the lateral displacement of the bracket 30.

[0029] The limiting post 15 is provided with a first guide slope 151, which guides the bracket 30 into the positioning groove 11. The upper end of the bionic positioning post 12 is provided with a second guide slope 121, which guides the bracket 30 into the positioning groove 11. When the bracket 30 to be assembled is aligned with the positioning groove 11 of the base 10, the edge of the bracket 30 first contacts the first guide slope 151 of the limiting post 15. The first guide slope 151 guides the bracket 30 to slide into the positioning groove 11 in the correct direction through its inclined structure, avoiding jamming. Simultaneously, the pre-set positioning hole of the bracket 30, guided by the second guide slope 121 at the upper end of the bionic positioning post 12, quickly fits into the bionic positioning post 12, achieving initial positioning of the bracket 30. After the bracket 30 is fully placed in the positioning groove 11, the positioning groove 11 restricts the lateral displacement of the bracket 30 through its adaptive contour. The bionic positioning post 12 further calibrates the position of the bracket 30, ensuring that the pre-set hole on the bracket 30 is precisely aligned with the stopping post of the base 10.

[0030] Please see Figure 3 The base 10 is provided with a stop post 16, which is located in the area of ​​the bracket 30 where the nut is installed. The stop post 16 is used to prevent the nut from being excessively inserted into the bracket 30. When the nut is installed to the appropriate depth, the end face of the nut just contacts the stop post 16, thereby preventing the nut from continuing to penetrate into the bracket 30.

[0031] Please see Figure 5The bracket 30 has a preset hole 31 corresponding to the through hole 21, and the nut is installed in the preset hole 31. The preset hole 31 has grooves 311 distributed around its periphery to engage with the anti-slip texture on the outer periphery of the nut. The nut is fed to the cover plate 20 above the through hole 21 and aligned with the through hole 21 by manual or automated feeding device. An implantation tool, such as a thermoforming pin, applies downward force along the through hole 21 to push the nut through the through hole 21 and into the preset hole 31 of the bracket 30. The through hole 21 guides the nut to be implanted vertically, avoiding tilting. When the nut is implanted to the preset depth, the lower end of the nut contacts the top of the stop post 16 of the base 10. The stop post 16 physically restricts the nut from moving further downward, preventing over-insertion. At the same time, the grooves 311 around the preset hole 31 engage with the anti-slip texture on the outer periphery of the nut to form a mechanical locking structure, enhancing the connection strength between the nut and the bracket 30.

[0032] The nut insertion fixture provided by this utility model features a synergistic design between the positioning groove 11 on the base 10 and the bionic positioning post 12. This design not only restricts the lateral displacement of the bracket 30 and enables rapid initial positioning, but also uses the bionic positioning post 12 to simultaneously and accurately position the bracket 30 and the cover plate 20, eliminating the cumulative errors of traditional separate positioning. The cover plate 20, which covers the positioning groove 11, not only restricts the vertical displacement of the bracket 30, effectively preventing the thin-walled plastic bracket 30 from deforming due to the pressure of the impact pin and the tilting of the nut during insertion, but also protects the non-processed areas of the bracket 30, reducing debris adhesion and surface scratches, and lowering the rate of appearance defects. The clearance through hole 21 on the cover plate 20 can guide the vertical insertion of the nut, preventing insertion deviation and poor engagement. At the same time, it serves as a visual marker to avoid omissions or misinstallation, improving the operational error tolerance rate.
