Description

Technical Field

[0001] The present invention relates to the field of metrology and verification technology, and more particularly to a VIN code engraving tool shared by multiple vehicle models. Background Art

[0002] The significance of a car's VIN: ASE standards stipulate that the VIN consists of 17 characters, commonly known as the "17-digit code." It contains information such as the vehicle's manufacturer, year, model, body type and code, engine code, and assembly location. Correctly interpreting the VIN is crucial for vehicle owners to accurately identify their vehicle model, enabling proper diagnosis and repair. The Vehicle Identification Number (VIN) is globally recognized, offering maximum information carrying capacity and searchability, making it the single "identity card" for vehicle identification worldwide. The VIN consists of 17 alphanumeric characters. The VIN identifies the vehicle's country of manufacture, manufacturer, type, make, model series, body style, engine model, model year, safety features, inspection digit, assembly plant name, and production serial number. Once a vehicle is stamped with a VIN, its code accompanies its registration, insurance, annual inspection, maintenance, repair, and even recycling.

[0003] Therefore, all major vehicle manufacturers require VIN coding tools to engrave VIN codes on vehicle body sheet metal. The coding tool's primary function is to position the sheet metal to be coded. Sufficient positioning stability is required to ensure consistent coding position and depth, complying with legal and regulatory requirements. Furthermore, the tool must be user-friendly and easy to use. Improving the positioning stability and convenience of coding tools has long been a research topic in the automotive industry. Existing coding tools can only code a single vehicle model and are not compatible with other models, lacking the ability to switch between models.

[0004] Therefore, how to provide a VIN code engraving tool that can realize the coding of multiple models on the same coding machine has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

DETAILED DESCRIPTION

[0035] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0036] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0037] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0038] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0039] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0040] according to Figures 1 to 6 As shown, the present invention provides a VIN code engraving tool that is common to multiple vehicle models, including an engraving base 1, a base plate 2, and multiple pressing mechanisms;

[0041] A notch 21 is provided on one side of the base plate 2, and the imprinting base 1 is fixed to the lower surface of the base plate 2 at the notch 21. The base plate 2 is provided with multiple locating pins on both sides of the notch 21, and a clamping mechanism is provided at each end of the base plate 2, which cooperates with the corresponding locating pins to fix the beam to be imprinted on the imprinting base 1. At least one of the clamping mechanisms at each end of the base plate 2 is in operation to clamp the left and right ends of the beam to be imprinted. During implementation, the locating pins in the present invention correspond to the locating holes on the beams of different vehicle models, thereby achieving initial positioning of the beam. To prevent the beam from shifting during the imprinting process, the present invention uses multiple clamping mechanisms that cooperate with the locating pins to achieve a clamping effect on the beam and ensure the imprinting quality. In addition, to adapt to different vehicle models of beams, at least two groups of the multiple clamping mechanisms in the present invention can be selected for use, and one group of the clamping mechanisms on both sides of the imprinting base 1 must be in operation to ensure sufficient clamping effect on the entire beam.

[0042] Furthermore, the clamping mechanism includes a first clamping mechanism 3, a second clamping mechanism 4, a third clamping mechanism 5 and a fourth clamping mechanism 6, and the positioning pins include a first positioning pin 71, a second positioning pin 81, a third positioning pin 91 and a fourth positioning pin 101. The first positioning pin 71, the second positioning pin 81, the third positioning pin 91 and the fourth positioning pin 101 respectively cooperate with the first clamping mechanism 3, the second clamping mechanism 4, the third clamping mechanism 5 and the fourth clamping mechanism 6 for positioning and clamping the beam to be engraved.

[0043] Furthermore, the first pressing mechanism 3 includes a first cylinder 31 , a first pressing arm 33 and a pressing head 34 .

[0044] The first cylinder 31 is fixed to the lower left end of the Base plate 2 through the first connecting plate 35, and a first rotating support 32 is provided on the top thereof for rotation connection. One end of the first pressing arm 33 is connected to the first rotating support 32, and the other end is connected to the pressing head 34, and the pressing head 34 is arranged on the lower side of the first pressing arm 33; a first pin seat 72 is provided on the Base plate 2, and a first adapter block 73 is provided on the first pin seat 72. The first positioning pin 71 is fixed on the first adapter block 73, and the pressing head 34 cooperates with the first positioning pin 71. During implementation, the first clamping mechanism 3 and the second clamping mechanism 4 are distributed on the left side of the engraving base 1. The first cylinder 31 drives the first rotating support 32 and the first pressing arm 33 to rotate, thereby driving the pressing head 34 to rotate through the first pressing arm 33. The positions of the pressing head 34 and the first positioning pin 71 correspond to each other. After the first positioning pin 71 and the beam are preliminarily positioned, the pressing head 34 can be used to clamp the upper surface of the beam.

[0045] Furthermore, the second pressing mechanism 4 includes a second cylinder 42 , a second pressing arm 44 and a first pressing iron 45 .

[0046] The second cylinder 42 is fixed above the left end of the Base plate 2 through the second connecting plate 41, and the end of its piston rod is rotatably connected to one end of the second pressure arm 44, and a second rotating support 43 is also connected between the second pressure arm 44 and the second cylinder 42, so that the second cylinder 42 drives the second pressure arm 44 to rotate around the fulcrum of the second rotating support 43; the first pressure iron 45 is arranged on the lower side of the end of the second pressure arm 44 away from the second cylinder 42; a second pin seat 82 is also provided on the Base plate 2, and a second adapter block 83 is provided on the second pin seat 82, the second positioning pin 81 is fixed on the second adapter block 83, and the first pressure iron 45 cooperates with the second positioning pin 81. The principle is the same as that of the first positioning mechanism, but the positioning holes of the beams of different existing models are relatively close to each other, so the first clamping mechanism 3 and the second clamping mechanism 4 may conflict with each other. Therefore, on the beams of different models, only one of the first clamping mechanism 3 and the second clamping mechanism 4 can be selected, but it does not affect the positioning effect of the first positioning pin 71 and the second positioning pin 81 on the beam.

[0047] Furthermore, the third clamping mechanism 5 includes a third cylinder 52, a third pressing arm 54 and a second pressing iron 55. The third cylinder 52 is fixed to the inner side of the right end of the base plate 2 through the third connecting plate 51, and the end of its piston rod is rotatably connected to one end of the third pressing arm 54. A third rotating support 53 is also connected between the third pressing arm 54 and the third cylinder 52, so that the third cylinder 52 drives the third pressing arm 54 to rotate around the fulcrum of the third rotating support 53; the second pressing iron 55 is arranged on the lower side of the end of the third pressing arm 54 away from the third cylinder 52; the base plate 2 is also provided with a third pin seat 92, and the third pin seat 92 is provided with a third adapter block 93. The third positioning pin 91 is fixed on the third adapter block 93, and the second pressing iron 55 cooperates with the third positioning pin 91. During implementation, the third clamping mechanism 5 and the fourth clamping mechanism 6 are distributed on the right side of the engraving base 1. After the third positioning pin 91 and the positioning hole on the beam are initially positioned, the third cylinder 52 drives the third pressing arm 54 to rotate through the third rotating support 53, so that the second pressure iron 55 can be attached to the upper surface of the beam.

[0048] Furthermore, a fourth pressing arm 56 is provided on the side of the third pressing arm 54, and a third pressure iron 57 is provided on the lower side of the end of the fourth pressing arm 56. A fourth pin seat 102 is also provided on the base plate 2, and a fourth adapter block 103 is provided on the fourth pin seat 102. The fourth positioning pin 101 is fixed on the fourth adapter block 103, and the third pressure iron 57 cooperates with the fourth positioning pin 101; the third cylinder 52 acts on the synchronous positioning of the third positioning pin 91 and the fourth positioning pin 101. During implementation, similar to the principle of the first clamping mechanism 3 and the second clamping mechanism 4 mentioned above, the present invention adds a fourth pressing arm 56 to the side wall of the third pressing arm 54, and acts on the surface of the beam through the second pressure iron 55 and / or the third pressure iron 57 to ensure stable compression of the right end of the beam.

[0049] Furthermore, the fourth pressing mechanism 6 includes a fourth cylinder 61, a fifth pressing arm 63 and a fourth pressing iron 64. The fourth cylinder 61 is fixed to the outer side of the right end of the Base plate 2, and the end of its piston rod is rotatably connected to one end of the fifth pressing arm 63, and a fourth rotating support 62 is also connected between the fifth pressing arm 63 and the fourth cylinder 61, so that the fourth cylinder 61 drives the fifth pressing arm 63 to rotate around the fulcrum of the fourth rotating support 62; the fourth pressing iron 64 is arranged on the lower side of the end of the fifth pressing arm 63 away from the fourth cylinder 61, and the fourth pressing iron 64 is pressed against the surface of the beam to be engraved. During implementation, generally, the lengths of most beams in the prior art are similar, but some models have longer beams that extend beyond the third clamping mechanism 5. At this point, the third and fourth clamping arms 54, 56 in the third clamping mechanism 5 cannot be effectively closed, rendering the third clamping mechanism 5 inoperable. To ensure the clamping effect on the longer beam, the present invention employs a fourth clamping mechanism 6 to clamp the beam. Although the third clamping mechanism 5 is inoperable, this does not affect the positioning effect of the third and fourth locating pins 91, 101 on the beam. Furthermore, a support block 65 is provided below the fourth pressure iron 64. The support block 65 is disposed on the base plate 2 to provide some support for the beam.

[0050] Furthermore, the first pin seat 72, the second pin seat 82, the third pin seat 92 and the fourth pin seat 102, the first adapter block 73, the second adapter block 83, the third adapter block 93 and the fourth adapter block 103 are all L-shaped structures, and the connection holes between the first pin seat 72, the second pin seat 82, the third pin seat 92 and the fourth pin seat 102 and the Base plate 2 are waist-shaped holes. Waist-shaped holes are provided on the sides of the first adapter block 73, the second adapter block 83, the third adapter block 93 and the fourth adapter block 103, so that the first positioning pin 71, the second positioning pin 81, the third positioning pin 91 and the fourth positioning pin 101 can be adjusted to their positions in X, Y and Z respectively. Ensure that the locating pins can accurately correspond to the multiple locating holes on the beam (in certain cases, at least two locating pins are required to correspond to the locating holes on the beam, and the remaining locating pins can be lowered through the waist-shaped holes to avoid conflict with the lower surface of the beam, which will cause the locating pins to be unable to be inserted into the corresponding locating holes), meeting the needs of most car beams.

[0051] Furthermore, the first pressure iron 45, the second pressure iron 55, the third pressure iron 57 and the fourth pressure iron 64 are respectively rotatably connected to the second pressure arm 44, the third pressure arm 54, the fourth pressure arm 56 and the fifth pressure arm 63 through pins, so that the clamping surfaces of the first pressure iron 45, the second pressure iron 55, the third pressure iron 57 and the fourth pressure iron 64 are always perpendicular to the surface of the beam to be engraved, thereby ensuring the clamping effect on the beam.

[0052] Furthermore, step supports 11 are provided on both sides of the notch 21 on the imprinting base 1, and a contour block 12 is provided above the right end of the base plate 2. The contour block 12 cooperates with the step support 11 to support the beam to be imprinted.

[0053] like Figure 7 As shown, this is the first embodiment of the present invention. The first vehicle beam 13 is positioned by the second locating pin 81 and the fourth locating pin 101. At the same time, the pin belts under the two locating pins support the coding beam. The second cylinder 42 and the third cylinder 52 are pressed and are in a pressed state, driving the two pressure irons to form two pressing points. The first cylinder 31 is in an open state and the fourth cylinder 61 is in a non-working state.

[0054] like Figure 8 As shown, this is the second embodiment of the present invention. The second vehicle beam 14 is positioned by the second locating pin 81 and the fourth locating pin 101. At the same time, the pin belts under the two locating pins play a supporting role facing the coding beam. The second cylinder 42 and the third cylinder 52 are pressed and are in a pressed state, driving the two pressure irons to form two pressing points. The first cylinder 31 is in an open state and the fourth cylinder 61 is in a non-working state.

[0055] like Figure 9 As shown, this is the third embodiment of the present invention. The third vehicle beam 15 is positioned by the second locating pin 81 and the fourth locating pin 101. At the same time, the pin belts under the two locating pins support the coding beam. The second cylinder 42 and the third cylinder 52 are pressed and are in a pressed state, driving the two pressure irons to form two pressing points. The first cylinder 31 is in an open state and the fourth cylinder 61 is in a non-working state.

[0056] like Figure 10 As shown, this is the fourth embodiment of the present invention. The fourth vehicle beam 16 is positioned by the first locating pin 71 and the third locating pin 91. At the same time, the pin belts under the two locating pins support the coding beam. The first cylinder 31 and the fourth cylinder 61 are pressed and are in a pressed state, driving the pressure head 34 and the fourth pressure iron 64 to form two pressing points. The second cylinder 42 is in an open state and the third cylinder 52 is in a non-working state.

[0057] For example Figure 11 As shown, it is a diagram of the movement trajectory of the engraving roller 17. There is no interference between the engraving roller 17 and the coding tooling during the movement, and there is sufficient space for movement.

[0058] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
