Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a vehicle door measuring tool. Background Art

[0002] Stamping is a common metal processing process that applies pressure to metal sheets to plastically deform them into the desired shape. Since the stamping process only requires one template to stamp and form sheets in large quantities, it is suitable for large-scale production and can produce large quantities of parts at a lower cost. For large metal parts such as car doors, the stamping process can achieve high-efficiency and low-cost production.

[0003] In the stamping workshop, the plate parts punched out by the stamping machine need to be measured by the stamping parts inspection fixture to ensure the accuracy of the stamping parts before they are assembled into the car body. When the new model project needs to confirm and analyze the accuracy of the stamping parts, there are multiple positions on the door outer panel and the door inner panel that need to be confirmed multiple times. At present, the door panel inspection fixtures used by most domestic automobile companies are dedicated. When in use, the inner panel and outer panel inspection fixtures are used separately; it is necessary to repeatedly confirm the poor accuracy position and value.

[0004] The design of separate inner panel gauges and outer panel gauges will first lead to the separate production and storage of inner and outer panel gauges, which increases manufacturing costs and storage space. At the same time, the inner and outer panels need to be measured separately, which reduces measurement efficiency. Secondly, due to inconsistent benchmarks of the gauges and inconsistent errors when fixing the inner and outer panels, the deviation during analysis is large, which reduces the accuracy of the door precision analysis.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture.

Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0033] In the stamping workshop, the plate parts punched out by the stamping machine need to be measured by the stamping parts inspection fixture to ensure the accuracy of the stamping parts before they are assembled into the car body. When the new model project needs to confirm and analyze the accuracy of the stamping parts, there are multiple positions on the door outer panel and the door inner panel that need to be confirmed multiple times. At present, the door panel inspection fixtures used by most domestic automobile companies are dedicated. When in use, the inner panel and outer panel inspection fixtures are used separately; it is necessary to repeatedly confirm the poor accuracy position and value.

[0034] The design of separate inner panel gauges and outer panel gauges will first lead to the separate production and storage of inner and outer panel gauges, which increases manufacturing costs and storage space. At the same time, the inner and outer panels need to be measured separately, which reduces measurement efficiency. Secondly, due to inconsistent benchmarks of the gauges and inconsistent errors when fixing the inner and outer panels, the deviation during analysis is large, which reduces the accuracy of the door precision analysis.

[0035] In order to solve the above problems, the utility model proposes a door measuring fixture 100. Figures 1 to 4 The door measuring fixture includes a support frame 1, a pillar assembly 2 and a plurality of fixing assemblies 3. A plurality of door reference assemblies 11 are arranged at intervals on one side of the support frame 1. The door reference assembly 11 is adapted to the outer side wall of the door 5 to be measured and is used to abut against the outer side wall of the door 5 to be measured. The door reference assembly 11 is used to provide a coordinate system reference for measurement for an external measuring device; the pillar assembly 2 includes an inner plate reference column 21 and an outer plate reference column 22. The inner plate reference column 21 is used to pass through the inner plate 51 of the door 5 to be measured and fix the inner plate 51, and the outer plate reference column 22 is used to pass through the inner plate 51 and the outer plate 52 of the door 5 to be measured in sequence and fix the outer plate 52; a plurality of fixing assemblies 3 are installed on the support frame 1 at intervals, and each fixing assembly 3 is used to pass through the inner plate 51 and abut against the surface of the inner plate 51 on the side away from the support frame 1.

[0036] It should be noted that the number of the inner panel reference columns 21 and the outer panel reference columns 22 are at least two, so as to improve the stability of the support and fixation of the vehicle door. There are holes on the plate of the vehicle door when stamping is completed. The fixing component 3, the inner panel reference column 21 and the outer panel reference column 22 all pass through the holes of the inner panel 51 and the outer panel 52 themselves. There is no need to open additional holes on the inner panel 51 or the outer panel 52, and it will not affect the performance of the inner panel 51 and the outer panel 52 themselves.

[0037] The technical solution of the utility model is to set an inner panel reference column 21 and an outer panel reference column 22 on the support frame 1, which are respectively used to fix and limit the inner panel 51 and the outer panel 52, and at the same time, the vehicle door 5 to be measured is fixed by pressing the outer side surface of the outer periphery of the vehicle door with the vehicle door reference component 11, and at the same time, the inner panel 51 is fixed by pressing the side of the inner panel 51 away from the support frame 1 with the fixing component 3, so that the inner panel 51 and the outer panel 52 of the vehicle door are fixed at the same time, and the inner panel 51 and the outer panel 52 share the same set of vehicle door reference components 11. When the outer panel 52 is inspected, the inner panel 51, the outer panel 52 and the edging of the vehicle door are fixed on the support frame 1 as a whole, and the outer panel 52 is inspected and the accuracy is confirmed by external measuring equipment. After the inspection of the outer panel 52 is completed, the outer panel 52 is removed, and the inner panel 51 is fixed by the fixing component 3 and will not deviate or detach. At this time, the inner panel 51 is exposed, and the wing accuracy of the inner panel 51 is inspected and confirmed by external measuring equipment. The present application fixes the inner panel 51 and the outer panel 52 on the same support frame 1, so that the inner panel 51 inspection fixture and the outer panel 52 inspection fixture share the same support frame 1, without taking up additional space, reducing the storage space occupied and reducing the manufacturing cost. At the same time, the design of sharing the same vehicle door reference assembly 11 makes it unnecessary to move or reinstall the inner panel 51 and the outer panel 52 during measurement, thereby reducing errors and improving the accuracy of precision analysis. In addition, the inner panel 51 and the outer panel 52 do not need to be repeatedly transported and installed, thereby reducing the accident rate and improving safety.

[0038] Please combine Figure 1 , Figure 2 and Figure 5 In one embodiment, the fixing assembly 3 includes a connecting rod 31 and a supporting rod 32. One end of the connecting rod 31 is connected to the supporting frame 1, and the other end is provided with the supporting rod 32, and the supporting rod 32 is used to press against the inner plate 51. The supporting rod 32 is connected to the connecting rod 31 and is arranged at an angle. After the connecting rod 31 extends into the inner plate 51 and the outer plate 52, the supporting rod 32 extends laterally to press against the side of the inner plate 51 away from the supporting frame 1, thereby improving the stability of the inner plate 51 support.

[0039] Furthermore, a support block 33 for pressing against the inner plate 51 is provided at one end of the support rod 32 away from the connecting rod 31, and the shape of the support block 33 matches the shape of the inner plate 51 in the pressing area. The support block 33 increases the contact area with the inner plate 51, and the shape of the support block 33 matches the shape of the inner plate 51 pressed against it, thereby improving the fit between the support block 33 and the inner plate 51, thereby improving the stability of the inner plate 51.

[0040] Specifically, the connecting rod 31 and the support rod 32 are detachably connected, and the support rod 32 and the support block 33 are detachably connected. The support rod 32, the connecting rod 31 and the support block 33 are all detachable, and the number of the support rod 32 and the support block 33 can be flexibly adjusted to adapt to the doors of more models and improve its applicability.

[0041] Furthermore, a storage box 17 is provided on the support frame 1, and the storage box 17 is used to store the connecting rod 31, the supporting rod 32 and the supporting block 33. The connecting rod 31, the supporting rod 32 and the supporting block 33 are stored in the storage box 17. When an additional supporting block 33, connecting rod 31 or supporting rod 32 needs to be installed, it can be directly taken out from the storage box 17 to improve efficiency. When the connecting rod 31, the supporting rod 32 or the supporting block 33 needs to be disassembled, the disassembled one is placed in the storage box 17 to prevent loss or misplacement to damage other components, thereby improving safety.

[0042] In one embodiment, the vehicle door measuring jig 100 further includes a reference block 14, the number of which is multiple and is arranged at intervals on the support frame 1, and the multiple reference blocks 14 form an annular reference area, which is arranged outside the vehicle door 5 to be measured on the support frame 1, and the reference block 14 is used to provide a coordinate system reference for measurement for an external measuring device. The reference block 14 is arranged around the vehicle door 5 to be measured on the support frame 1 to provide a coordinate system reference to prevent the reference block 14 from being blocked by the vehicle door, thereby improving the measurement accuracy.

[0043] Please combine Figure 1 , Figure 2 and Figure 6 In one embodiment, each door reference assembly 11 is further provided with a limit assembly 15, which includes a card 151 and a buckle 152. The card 151 is used to abut against the outer panel 52 of the door 5 to be measured, and the buckle 152 is fixed to the door reference assembly 11 and used to engage with the card 151 to fix the card 151 to the door reference assembly 11. The limit assembly 15 abuts against the outer panel 52, which can fix the outer panel 52 to a certain extent and improve the stability of the outer panel 52. On the other hand, it makes the connection between the outer panel 52 and the door reference assembly 11 more stable, prevents deviation during the measurement process, and improves the accuracy of the precision measurement.

[0044] Specifically, each door reference assembly 11 includes a connecting column 12, a clamping assembly 13 and a reference block 14. One end of the clamping assembly 13 is connected to the connecting column 12, and the other end is in contact with the reference block 14, so that the reference block 14 is clamped between the clamping assembly 13 and the door 5 to be measured. It can be understood that the outer edge of the door is usually arc-shaped, resulting in different distances between the outer edge and the support frame 1 at different positions. Therefore, the reference block 14 is matched and pressed against the outer edges at different distances by setting connecting columns 12 of different lengths, thereby improving the stability of the connection between the reference block 14 and the door. The degree of fastening between the reference block 14 and the outer edge of the door is adjusted by the clamping assembly 13, thereby adjusting the clamping force for the door.

[0045] In one embodiment, the clamping assembly 13 includes a clamping plate 131, a clamping rod 132 and a screw 133. One end of the clamping rod 132 is mounted on the connecting column 12 by means of the screw 133, and the other end of the clamping rod 132 is connected to the clamping plate 131 and is used to press the clamping plate 131 against the reference block 14. The clamping rod 132 is rotatable relative to the connecting column 12, so as to adjust the degree of tightening between the clamping rod 132 and the reference block 14. After the reference block 14 is clamped to the vehicle door, the clamping rod 132 is fixed by means of the screw 133. When disassembly is required, the reference block 14 can be disassembled by only loosening the screw 133, so that the reference block 14 can be adapted to different types of vehicle door edges by means of adjustment, thereby improving its applicability.

[0046] In one embodiment, an auxiliary reference member 16 is further provided at the bottom of the support frame 1. The auxiliary reference member 16 is used to abut against the bottom edge of the vehicle door 5 to be measured and support the vehicle door 5 to be measured. The auxiliary reference member 16 is used to provide a coordinate system reference for measurement for an external measuring device. The auxiliary reference member 16 increases the number of supporting points for the vehicle door 5 to be measured and improves its stability. On the other hand, it provides a coordinate system reference again, thereby improving the accuracy of precision measurement.

[0047] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
