Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tooling fixtures for automobile painting, and more specifically, to a universal measuring tool for measuring the positioning dimensions of vehicle doors. Background Art

[0002] Automotive sealant is a white paste-like high-viscosity fluid at room temperature. It uses high-strength polyvinyl chloride resin as the main material. After high-temperature cross-linking and curing, it can firmly adhere to the electrophoretic sheet, playing the role of rust prevention, waterproofing, sealing, sound insulation and improving the commercial quality of the appearance. Sealant coating operation is one of the main operations in a paint shop.

[0003] When applying sealant to the car door, the car door needs to be stably and reliably fixed, and the operation will not be abnormal due to the shaking of the car door. Mainstream automobile OEMs mainly limit the car door through two methods: door limit fixtures and door positioning rods to ensure the stability of the door opening state during the sealant door operation. Commonly used door strut styles are: by slotting at different positions to meet the needs of different door openings. Before manufacturing the door strut, the location of the slot needs to be accurately determined to avoid the door strut falling off or the door strut being unable to be installed due to inconsistent dimensions.

[0004] In order to determine the grooving position, the current solution is to use manual measurement. The specific method is to use a ruler to measure the distance d from the door process hole to the body process hole, preliminarily take an angle θ of the support rod, and then determine the grooving point based on the distance d from the door process hole to the body process hole after the front section size L is determined. A verification product is made, and actual vehicle verification is carried out, and continuous adjustments are made until the size and style meet the operational requirements.

[0005] The problems with this solution are: during the development process, since the left and right doors are mirror images of each other and the front and rear doors generally have different opening degrees, it is necessary to produce four sets of door struts for verification. On this basis, continuous verification and adjustment are performed to obtain the most suitable size data for the operation. After each adjustment, the manufacturer needs to adjust the mold and then send the sample to the operation line for verification. This requires a long production and logistics time. This solution leads to a lot of duplication of work and increases the production cycle and cost of the door struts. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a universal measuring tool for measuring the positioning size of a vehicle door, which is provided with an angle adjuster and a second connecting rod and a telescopic rod with adjustable lengths. By adjusting the angle adjuster to adjust the angle between the first connecting rod and the second connecting rod, and adjusting the lengths of the second connecting rod and the telescopic rod to match vehicle door openings of different openings and different sizes, the measurement of different vehicle door positioning sizes can be achieved.

[0024] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0025] Example 1

[0026] like Figure 1 As shown, a universal measuring tool for measuring the positioning size of a vehicle door comprises a first connecting rod 1, an angle adjuster 2, a second connecting rod 3 and a telescopic rod 4. The free end of the first connecting rod 1 is used to be inserted into a process hole of a vehicle body. The other end of the first connecting rod 1 and one end of the second connecting rod 3 are respectively connected to the angle adjuster 2 to adjust the angle between the first connecting rod 1 and the second connecting rod 3. One end of the telescopic rod 4 is telescopically connected to the second connecting rod 3, and the other end of the telescopic rod 4 is used to be clamped into the flange edge of the door lock installation opening. One end of the telescopic rod 4 is inserted into the second connecting rod 3, and the other end is clamped into the door lock installation opening. The telescopic rod 4 can be adjusted to match the opening of different vehicle doors by adjusting the length of the second connecting rod 3. The first connecting rod 1 is inserted into the process hole of the vehicle body, and the angle between the first connecting rod 1 and the second connecting rod 3 can be adjusted by the angle adjuster 2. By adjusting the length of the telescopic rod 4 extending out of the second connecting rod 3, and by adjusting the angle adjuster 2 to adjust the angle between the first connecting rod 1 and the second connecting rod 3, the universal door positioning dimension measuring tool can determine the position information of the door lock installation port and the vehicle body process hole at the maximum opening, providing a basis for the subsequent production of the door positioning rod. The structure of the universal door positioning dimension measuring tool is similar to that of the door positioning rod, and it can simulate the positioning effect of the door positioning rod of the same size during use, ensuring the quality of the produced door support rod.

[0027] like Figure 2As shown, the angle adjuster 2 includes a body 22 and a rotating member 21. The body 22 is provided with a rotating mounting hole 221, which is a blind hole. The rotating member 21 is installed in the mounting hole 221 and is rotatably connected thereto; the rotating member 21 is connected to one end of the first connecting rod 1, and the body 22 is connected to one end of the second connecting rod 3. The mounting hole 221 is a blind hole, which limits the rotating member 21 installed in the mounting hole 221. The mounting hole 221 is a circular hole, and the rotating body 21 is also circular, so that the rotating body 21 can be matched and installed in the mounting hole 221 when it is rotated to any angle.

[0028] like Figure 1 As shown, a through first fixing hole is provided in the center of the body 22, and the first fixing hole is connected to the mounting hole 221. A through second fixing hole is provided in the center of the rotating member 21, and fasteners are installed in the first fixing hole and the second fixing hole. The fastener is a fastening bolt, which can be matched with the blind hole structure of the mounting hole 221 provided on the body 22 to fix the position of the rotating member 21 and connect the body 22 with the mounting hole 221. The fastener is located in the center of the body 22 and the rotating member 21, and can serve as the rotating axis of the two when the body 22 and the rotating member 21 rotate relative to each other. When the angle adjuster 2 is used to adjust the angle, the fastening bolt is loosened, the rotating member 21 is taken out of the mounting hole 221, and after adjusting to a suitable angle, the rotating member 21 is placed in the mounting hole 221, and then the fastening bolt is tightened to adjust the angle.

[0029] like Figure 2 As shown, the inner wall surface of the mounting hole 221 is a toothed surface, and the outer peripheral surface of the rotating member 21 is a toothed surface, and the toothed surface of the mounting hole 221 meshes with the toothed surface of the rotating member 21. The outer peripheral surface of the rotating member 21 and the inner wall surface of the mounting hole 221 are meshed toothed surfaces, forming a structure similar to a spline, so that the angle adjuster 2 can adjust the angle as a unit of a single tooth on the toothed surface, ensuring that the angle adjuster 2 will not deflect after being adjusted to a certain angle and fixed. When adjusting the angle of the angle adjuster 2, remove the rotating member 21 from the mounting hole 221, then rotate the rotating member 21 to a suitable angle, and then install it back into the mounting hole 221. After the angle is adjusted, if relative rotation occurs between the rotating body 21 and the main body 22, the toothed surface of the mounting hole 221 will conflict with the toothed surface of the rotating member 21, thereby limiting the relative rotation between the rotating body 21 and the main body 22, thereby ensuring the working stability and use accuracy of the angle adjuster 2, and preventing the angle from deflecting due to other reasons other than manual adjustment.

[0030] like Figure 2As shown, the number of teeth of the toothed surface of the mounting hole 221 and the toothed surface of the rotating member 21 is 60. The cross-sections of the mounting hole 221 and the rotating member 21 are both circular, and one circle is 360°. The number of teeth of the toothed surface of the mounting hole 221 and the toothed surface of the rotating member 21 is 60, and the reading of the rotation of a single tooth is 6°. Therefore, the angle sensor 2 can realize the angle adjustment in units of 6°, and the angle of rotation of the angle adjuster 2 can be directly obtained by calculating the number of teeth rotated, without the need to use other angle measuring tools for measurement, making the angle measurement convenient and fast, and increasing the efficiency of measurement.

[0031] Example 2

[0032] This embodiment is similar to the above-mentioned embodiment 1, except that: Figure 2 As shown, a threaded hole 31 is provided at one end of the second connecting rod 3 away from the angle adjuster 2, and a thread is provided on the outer peripheral surface of one end of the telescopic rod 4, and the threaded end of the telescopic rod 4 is inserted into the threaded hole 31 and threadedly connected thereto. Doors of different specifications have different openings, and the required door support rod lengths are also different. Therefore, if the door positioning dimension measuring tool is to be universal, it is necessary to have a length adjustment structure. The second connecting rod 3 is threadedly connected to the telescopic rod 4, and the telescopic rod 4 can extend from or into the second connecting rod 3 through the threaded structure, thereby achieving length adjustment.

[0033] like Figure 1 As shown, the outer peripheral surface of the other end of the telescopic rod 4 is provided with a plurality of annular grooves 41 along the length direction of the telescopic rod 4. The end of the telescopic rod 4 away from the second connecting rod 3 needs to be inserted into the flange edge of the door lock installation port. The telescopic rod 4 is a cylindrical structure with a relatively smooth surface. If the telescopic rod 4 is directly inserted into the flange edge of the door lock installation port, the telescopic rod 4 is prone to relative sliding with the door lock installation port, which directly affects the measurement accuracy of the universal door positioning size measuring tool, resulting in the door support rod produced later being unable to adapt to the door and the body. Therefore, it is necessary to set a groove-like structure on the telescopic rod 4 to clamp the flange edge. When the telescopic rod 4 slides relative to the flange edge of the door lock installation port, the groove-like structure will conflict with the flange edge, thereby limiting the relative sliding and ensuring the stability of the position of the universal door positioning size measuring tool. Since the telescopic function of the telescopic rod 4 is realized by the threaded connection with the second connecting rod 3, the telescopic rod 4 needs to be rotated to realize the telescopic extension to different lengths in the threaded structure, so the telescopic rod 4 may be stuck to the flange edge at any point on the circumference of the telescopic rod 4. Therefore, the groove structure is designed as an annular groove 41

[0034] like Figure 1As shown, the outer circumference of the other end of the telescopic rod 4 is linearly arranged with a plurality of disc-shaped structures, and an annular groove 41 is formed between each disc-shaped structure. The telescopic rod 4 itself is an integrally formed rod-shaped structure. If the annular groove 41 is directly formed on the body of the telescopic rod 4, it is easy to cause the telescopic rod 4 to break due to uneven stress distribution. Therefore, by linearly arranging a plurality of disc-shaped structures on the outer circumference of the telescopic rod 4, an annular groove 41 is formed between the disc-shaped structures, and the structure of the body of the telescopic rod 4 is not damaged, thereby reducing the possibility of the telescopic rod 4 breaking.

[0035] Example 3

[0036] This embodiment is similar to the above-mentioned embodiment 1, except that: Figure 1 As shown, the free end of the first connecting rod 1 is provided with an insertion rod 11, which is coaxial with the first connecting rod 1. The insertion rod 11 is used to be inserted into the body process hole, and abuts against the body process hole to fix the position of the universal door positioning size measuring tool.

[0037] like Figure 1 As shown, the diameter of the first connecting rod 1 is larger than the diameter of the body process hole, and the diameter of the insertion rod 11 is smaller than the body process hole. There is a difference between the diameter of the first connecting rod 1 and the diameter of the insertion rod 11, so that a platform is formed at the connection between the first connecting rod 1 and the insertion rod 11, so that the body process hole and the platform conflict when the universal door positioning size measuring tool is used, limiting the movement of the universal door positioning size measuring tool. The diameter of the first connecting rod 1 is larger than the diameter of the body process hole, and the diameter of the insertion rod 11 is smaller than the body process hole, ensuring that only the insertion rod 11 of the universal door positioning size measuring tool can extend into the body process hole.

[0038] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
