Description

Technical Field

[0001] This invention relates to the field of vehicle component installation technology, specifically to a special tool for adjusting and inspecting the height of a roof rack. Background Technology

[0002] During the assembly of a car roof rack, the roof rack mounting studs pass through the outer side panel, and the height adjustment nut is secured to the inner side panel via a fixing nut. The gap between the roof rack and the outer panel can be controlled by screwing the height adjustment nut in and out. After tightening the height adjustment nut, it needs to be adjusted according to the actual gap between the roof rack and the outer panel to ensure the aesthetics of the gap between the roof rack and the side panel after assembly. Due to the special internal adjustment and tightening structure of the height adjustment nut, a special tool is required for tightening. Without the use of a special tool, the adjustment process cannot be implemented. After tightening, it is also necessary to measure whether the tightened height value is qualified. Traditional feeler gauges require multiple measurements, which wastes time and contains errors. Incorrect height adjustment will result in poor aesthetics of the gap between the roof rack and the outer panel. Interference between the roof rack and the outer panel will also cause surface defects, leading to serious complaints from users and affecting product competitiveness.

[0003] Invention Patent Content

[0004] To address the aforementioned problems, this invention provides a tool for adjusting and detecting the screw-out height of a height-adjusting nut. By adapting the tool and the detection tool to the height-adjusting nut, the tool allows for convenient and quick precise adjustment of the screw-out height of the height-adjusting nut. The objective of this invention is achieved through the following technical solution:

[0005] This invention provides a tool for adjusting and detecting the unscrewing height of a height-adjusting nut, comprising an adjustment tool and a detection tool. The adjustment tool has a screwing part with a columnar shape that adapts to the inner circumferential structure of the adjustment hole of the height-adjusting nut. Preferably, the screwing part has a prismatic shape, such as a hexagonal prism structure. The detection tool has a first measuring part with a first inner hole. The axial depth of the first inner hole is consistent with the first target height of the axial height adjustment of the unscrewing section of the height-adjusting nut. The inner diameter of the first inner hole is larger than the outer diameter of the unscrewing section of the height-adjusting nut.

[0006] Furthermore, the adjustment tool also has a handle, which is axially centered with the screwing part.

[0007] Furthermore, the adjustment tool also has a connecting part, which is axially connected between the handle and the screwing part. The radial cross-sectional dimension of the connecting part is larger than the radial cross-sectional dimension of the screwing part and smaller than the radial cross-sectional dimension of the handle.

[0008] Furthermore, the screwing part and the connecting part of the adjustment tool are detachably connected.

[0009] Furthermore, the detection tool has a gripping part, which is connected to the first measuring part.

[0010] Furthermore, the detection tool has a second measuring part, which has a second inner hole. The axial depth of the second inner hole is consistent with the second target height of the axially extended portion of the height adjusting nut. The inner diameter of the second inner hole is larger than the outer diameter of the axially extended portion of the height adjusting nut.

[0011] Furthermore, the first bottom surface of the first measuring part forming the first inner hole has an arcuate surface adapted to the surface of the component on which the height adjustment nut is installed; preferably, the first bottom surface of the second measuring part forming the second inner hole has an arcuate surface structure that can fit and conform to the surface of the component on which the height adjustment nut is installed.

[0012] Furthermore, the first inner hole and / or the second inner hole are through holes that penetrate the thickness of the first measuring part and / or the second measuring part.

[0013] Furthermore, the first measuring part and the second measuring part are connected by a gripping part. The first measuring part has a first ring portion surrounding a first inner hole, and the second measuring part has a second ring portion surrounding a second inner hole. The outer diameter of the first ring portion and / or the second ring portion is greater than the width of the gripping part.

[0014] The beneficial effects of this invention are as follows:

[0015] (1) When adjusting the screw-out height of the height adjusting nut using the tool of the present invention, the screwing part of the adjusting tool is inserted into the first end adjustment hole of the adjusting nut, and the detection tool is placed at the screw-out end of the adjusting nut. The screwing out height of the screw-out end of the adjusting nut is made consistent with the height of the first detection part or the second detection part of the detection tool by the adjusting tool screwing the inner ring of the adjusting nut. The screw-out height of the adjusting nut is consistent with the height of the first detection part or the second detection part of the detection tool. The screw-out height of the nut can be quickly screwed in and out according to the batch status, so that the screw-out part of the height adjusting nut extends axially to a suitable height, ensuring that the adjustment process can be implemented normally. This makes the gap of the luggage rack after assembly qualified, increases the aesthetics of the product, and also avoids the problem of the height nut tilting due to the use of needle-nose pliers.

[0016] (2) The tool structure of the present invention is simple and easy to manufacture. Various specifications of testing tools can be prefabricated according to actual needs. When using it, the corresponding specification of testing tool can be selected and used together with the adjustment tool to achieve precise adjustment of the height adjustment nut screwing out.

[0017] (3) By setting two types of testing parts on the testing tool, the height adjustment nuts of two different target heights can be adjusted with one set of tools. The tool is simpler, more integrated, economical and efficient. Attached Figure Description

[0025] Example 1:

[0026] This embodiment provides a tool for adjusting and detecting the unscrewing height of a height-adjusting nut, which includes an adjustment tool 200 and a detection tool 300.

[0027] In the illustrated embodiment, the adjustment tool 200 has a screwing part 210, a connecting part 220, and a handle 230, as shown. Figure 1 and Figure 2 As shown, the screwing part 210 has a columnar shape that adapts to the circumferential structure of the first end adjustment hole 111 of the height adjustment nut 100, and is shown as a hexagonal prism structure; the connecting part 220 is axially connected between the handle 230 and the screwing part 210, and the radial cross-sectional dimension of the connecting part 220 is larger than the radial cross-sectional dimension of the screwing part 210 and smaller than the radial cross-sectional dimension of the handle 230.

[0028] In a preferred embodiment, the handle 230, the connecting part 220 and the screwing part 210 are axially centered and connected; the screwing part 210 and the connecting part 220 of the adjustment tool can be integrally cast, or they can be fastened by welding, gluing or other fastening methods, or they can be detachable connection structures.

[0029] In the illustrated embodiment, the detection tool 300 has a first measuring part 310, a gripping part 330, and a second measuring part 320, as shown. Figure 4 and Figure 5 As shown, the first measuring part 310 has a first inner hole 311, the axial depth of which is consistent with the first target height of the component on which the height adjusting nut is screwed out, and the inner diameter of the first inner hole 311 is larger than the outer diameter of the height adjusting nut screw-out section 110; the second measuring part 320 has a second inner hole 321, the axial depth of which is consistent with the second target height of the height adjusting nut screw-out section 110 (normally, the second target height and the first target height are slightly different), and the inner diameter of the second inner hole is larger than the outer diameter of the height adjusting nut screw-out section.

[0030] In a preferred embodiment, the first bottom surface of the first measuring portion 310, which forms a first inner hole 311, has an arcuate surface adapted to the surface structure of a component (such as a roof or frame) for mounting a height-adjusting nut; the first bottom surface of the second measuring portion 320, which forms a second inner hole 321, has an arcuate surface adapted to the surface structure of a component for mounting a height-adjusting nut. The first measuring portion 310 and the second measuring portion 320 are connected by a gripping portion 330.

[0031] In the illustrated embodiment, the first measuring part 310 has a first annular portion surrounding a first inner hole, and the second measuring part 320 has a second annular portion surrounding a second inner hole. The outer diameter of the first and / or second annular portions is larger than the width of the gripping part 330 to facilitate stable gripping. In other embodiments, the first and second annular portions can also adopt a non-closed structure. For example, openings can be provided in the first and second annular portions respectively at positions away from the gripping part 330, so that when the height adjusting nut has complex connection structures at both ends, making it inconvenient to insert the testing tool axially, it can be inserted radially into the unscrewed section of the height adjusting nut to achieve the same axial unscrewed height adjustment of the unscrewed section.

[0032] In the illustrated embodiment, the first inner hole 311 and the second inner hole 321 are circular through holes that penetrate the thickness of the first measuring part 310 and the second measuring part 320, respectively. However, in other embodiments, the first inner hole 311 and the second inner hole 321 can also adopt a blind hole structure, as long as the depth of the blind hole meets the adjustment target requirements. During the adjustment process, ensure that the bottom of the first measuring part or the second measuring part is attached to the surface of the component on which the adjusting nut is assembled, and then use an adjusting tool to screw the outer end of the screwing section of the adjusting nut to the bottom of the blind hole to achieve the adjustment target.

[0033] Example 2:

[0034] This embodiment shares the same technical principle as Embodiment 1, but differs in that it provides a specific tool and its application method based on the scenario of adjusting the gap between the height-adjusting nut and the side panel after the roof rack is assembled. The handle 230 can be a cylinder with a radius R20mm and a height of 26mm, with 5mm chamfers on the top and bottom edges. The connecting part 220 adopts a rod-like structure and is located on the upper part of the handle 230. The connecting part 220 is a cylinder with a radius R8mm and a height of 106mm. The connecting part 220 and the handle 230 are either integrally formed or detachably connected. The screwing part 210 is located on the upper part of the connecting part 220. The screwing part 210 is a regular hexagon with a height of 20mm. The hexagonal cross-section can mate with the inner circumferential structure of the height-adjusting nut's adjusting hole, allowing for screwing in and out for adjustment. 210 and the connecting part 220 can be detachably connected or integrally formed together; the testing tool 300 includes a central gripping part 330, which is 73mm long, 13mm wide, and 2.6mm high. The gripping part 330 has a chamfer of R2mm at its edge. A first measuring part 310 and a second measuring part 320 are provided on both sides of the gripping part 330. The bottom surfaces of the first measuring part 310 and the second measuring part 320 are designed to conform to the shape of the inner panel of the vehicle body. The first inner hole 311 and the second inner hole 321 are circular and can be matched with the outer diameter of the screw-out section 110 of the height adjustment nut 100. The thickness of the first measuring part 310 can be selected from the theoretical height of the screw-out section of the height adjustment nut protruding from the outer panel of the vehicle body, which is 2.3mm. The thickness of the second measuring part 320 can be selected from the thickness of the first measuring part by increasing by 0.3mm, which is 2.6mm. The gripping part 330, the first measuring part 310, and the second measuring part 320 can be integrally molded and connected, and the part where the gripping part 330 is connected to the first measuring part 310 is chamfered with an R0.1mm.

[0035] The problem solved and the effect of this embodiment is: by adjusting the height nut 100 by using the adjustment tool 200 and the detection tool 300 to screw it in and out, and by using the detection tool to confirm that the support height is screwed to a qualified state, the gap between the luggage rack and the side panel is guaranteed to be qualified.

[0036] When using, hold the handle 230 and insert the screwing part 210 of the adjustment tool 200 into the adjustment hole 111 of the height adjustment nut. Screw in and out the support part to adjust the protruding height of the screw-out section 110 of the nut. During adjustment or after one round of adjustment, use the testing tool 300 to check. Place the first measuring part 310 or the second measuring part 320 on the height support part of the height adjustment nut to check if it is flush. If it meets the requirements, the adjustment is complete. If it does not meet the requirements, repeat the adjustment steps until the adjustment and inspection are qualified, ensuring the aesthetic appearance of the gap between the luggage rack and the top cover after assembly.

[0037] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention; the dimensions described in the drawings and embodiments are not related to the specific physical object and are not used to limit the protection scope of the present invention. The physical dimensions can be selected and changed according to actual needs.
