Description

Technical Field

[0001] This utility model relates to the field of mechanical tooling technology, specifically to an inspection device for the butt joint angle of sealing strips. Background Technology

[0002] Cars are a common means of transportation and have entered ordinary people's households.

[0003] Automobiles are equipped with various rubber sealing strips (rubber seals) to provide cushioning for components or to seal the vehicle. Sealing strips in areas such as car doors, door openings, and the trunk require bending at corners during installation. Therefore, the rubber sealing strips must be inspected before installation to check for cracks or splits after bending. This inspection involves the operator manually bending the sealing strip and then visually observing the mating corners.

[0004] The inventors of this application have discovered that, currently, during inspection, the results vary depending on the operator's hand grip, bending angle, and bending force. If the bending angle is too small, defective products may go undetected during inspection and be released; if the bending angle is too large, it may result in batch defects in the sealing strips.

[0032] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0033] As described in the background section of this application, the sealing strips for automobile doors, door openings, and trunks need to be bent at corners during installation. Therefore, the rubber sealing strips must be inspected before installation to check for cracks or splits after bending. The inspection is performed by the operator manually bending the sealing strip and then visually observing the mating corners.

[0034] The inventors of this application have discovered that, currently, during inspection, the results vary depending on the operator's hand grip, bending angle, and bending force. If the bending angle is too small, defective products may go undetected during inspection and be released; if the bending angle is too large, it may result in batch defects in the sealing strips.

[0035] To address the aforementioned problems, the inventors of this application have proposed a technical solution, the specific embodiments of which are as follows:

[0036] Figure 1 This is a schematic diagram of the inspection device for the butt joint angle of the sealing strip in an embodiment of this utility model. Figure 2 This is a schematic diagram of the inspection fixture in an embodiment of the present utility model. Figure 3 This is a schematic diagram showing the usage state of the inspection device in an embodiment of this utility model.

[0037] like Figure 1 and Figure 2 As shown, the inspection device for the butt joint corner of the sealing strip in this embodiment includes: a bracket 1 and an inspection fixture 2.

[0038] The bracket 1 is fixedly mounted on the workbench 3.

[0039] The inspection fixture 2 is mounted on the support 1 and is located at the top of the support 1.

[0040] The inspection fixture 2 is roughly fan-shaped and has a symmetrical structure. The inspection fixture 2 includes a flat part 21 and an arc-shaped part 22.

[0041] The two flat portions 21 of the inspection fixture 2 are located on the left and right sides of the arc portion 22, respectively. The flat portions 21 of the inspection fixture 2 are inclined upwards, and the two flat portions 21 form a figure-eight shape. The arc portion 22 is convex, and the two flat portions 21 are smoothly connected through the middle arc portion 22.

[0042] like Figure 3 As shown, in this embodiment of the inspection device, during use, the operator holds the sealing strip approximately 100mm from both sides of the butt joint angle. The sealing strip 100 is placed on the top surface of the inspection fixture, and the sealing strip is bent downwards so that it fits against the flat and arc-shaped parts of the inspection fixture, with the butt joint angle of the sealing strip located at the arc-shaped part of the inspection fixture. The bending angle of the sealing strip is the included angle between the two flat parts of the inspection fixture. The hollow part, vent part, and base of the sealing strip are bent in various directions according to the cross-sectional angle of the sealing strip to confirm its integrity. After bending, the operator visually inspects the butt joint angle of the sealing strip to check for any cracked defects.

[0043] As can be seen from the above, the inspection device for the butt joint angle of the sealing strip in this embodiment, by setting up a bracket and an inspection fixture, includes a flat part and an arc part. The flat part is located on both sides of the arc part and is inclined. The two flat parts form a figure-eight shape and are connected by the arc part. In use, the operator holds both sides of the butt joint angle of the sealing strip with both hands, places the sealing strip on the inspection fixture, and bends the sealing strip downward so that it fits against the top surface of the inspection fixture, with the butt joint angle of the sealing strip located at the arc part of the inspection fixture. The operator visually observes the butt joint angle of the sealing strip to check for cracks or defects. The structure is simple, and the sealing strip is bent at the same angle during inspection, which standardizes the inspection method, reduces the risk of defective products flowing out, and prevents damage to the sealing strip due to excessive bending angle.

[0044] Optionally, in this embodiment, the bracket 1 for inspecting the joint corner of the sealing strip includes: a base 11, a support column 12, and a fixing seat 13.

[0045] The base 11 is set on the workbench 3, the bottom end of the support column 12 is set on the base 11, and the fixed seat 13 is set on the top end of the support column 12.

[0046] The inspection fixture 2 is mounted on the fixed seat 13 of the bracket 1.

[0047] Furthermore, in this embodiment, the inspection device for the joint corner of the sealing strip is such that the support column 12 is connected and fixed to the base 11 and the fixing seat 13 by welding.

[0048] Furthermore, in this embodiment, the inspection device for the joint corner of the sealing strip has a U-shaped fixing seat 13 with a U-shaped groove on its top surface, and the inspection fixture 2 is embedded in the U-shaped groove of the fixing seat 13.

[0049] Furthermore, in this embodiment, the inspection fixture 2 for the inspection device used for the butt joint of the sealing strip is made of nylon.

[0050] Nylon has advantages such as low coefficient of friction and good wear resistance. Inspection fixture 2 is made of nylon material, which can reduce wear on the sealing strip and will not damage the sealing strip.

[0051] Furthermore, in this embodiment, the inspection fixture 2 for inspecting the butt joint angle of the sealing strip has a height greater than the depth of the U-shaped groove of the fixing seat 13. The inspection fixture 2 is embedded in the U-shaped groove of the fixing seat, so that the top surface of the inspection fixture 2 protrudes from the top surface of the fixing seat 13. During inspection, the sealing strip will not come into contact with the fixing seat 13, preventing the fixing seat from damaging the sealing strip.

[0052] Furthermore, in this embodiment, the fixing base 13 of the inspection device for the joint corner of the sealing strip has two connecting through holes on the side wall of the U-shaped groove.

[0053] The side wall of the inspection fixture 2 is provided with two first threaded holes 201. The connecting bolt 41 passes through the connecting through hole of the fixed seat 13 and engages with the first threaded hole 201 of the inspection fixture 2, so that the inspection fixture is stably fixed on the fixed seat.

[0054] Furthermore, in this embodiment, the inspection device for the mating corner of the sealing strip has a mounting through hole on the base 11. The fixing screw 42 passes through the mounting through hole of the base 11 and engages with the threaded hole of the worktable 3, so that the base 11 is fixed on the worktable.

[0055] Furthermore, in this embodiment, the inspection fixture 2 for the sealing strip joint angle inspection device has a planar portion 21 that is inclined upwards, an included angle of 150° between the two planar portions 21, an arc radius of approximately 30mm for the arc portion 22 of the inspection fixture 2, and a thickness of approximately 35mm in the vertical direction.
