Description

Technical Field

[0001] This utility model belongs to the technical field of clamps for stamping vehicle VINs, and more specifically, relates to a clamping assembly and clamp for stamping vehicle VINs. Background Technology

[0002] VIN (vehicle identification number) is a set of characters assigned to a vehicle by the vehicle manufacturer to identify a particular vehicle. The car manufacturer uses a special fixture to engrave the vehicle's VIN. The fixture firmly fixes the engraving equipment above the crossbeam on which the VIN is to be engraved. The cylinder on the fixture is manually controlled to extend and retract, which drives the clamping assembly to clamp the sheet metal holes on both sides of the crossbeam.

[0003] The height of the upper edge of the sheet metal holes varies for different car models, and different car models require different clamping components. When switching between car models, the clamping components need to be replaced manually, which increases labor hours and reduces work efficiency. Utility Model Content

[0025] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0026] like Figure 1-2 As shown, this embodiment provides a clamping assembly for stamping vehicle VINs, including:

[0027] A pair of clamping components 1, each pair of clamping components 1 having at least two pairs of L-shaped positioning surfaces, wherein at least two positioning surfaces on each clamping component 1 are arranged from top to bottom to form a stepped shape.

[0028] Specifically, different positioning surfaces are used for different vehicle models. When production switches to different vehicle models, different positioning surfaces are used to position the crossbeam 4 of the VIN to be engraved. There is no need to change the fixtures and clamping components, which can enable continuous production, reduce labor hours and improve work efficiency.

[0029] In use, a pair of clamping components 1 are installed on the fixture. The pair of clamping components 1 are placed at the sheet metal holes 5 on both sides of the crossbeam 4 to be engraved with VIN. The cylinder on the fixture is manually controlled to extend and retract. The cylinder drives the pair of clamping components 1 to clamp the upper edge 6 of the sheet metal hole, thereby achieving clamping and positioning of the crossbeam 4.

[0030] Optionally, each positioning surface has a front and a bottom surface.

[0031] In this embodiment, the clamping component 1 has two positioning surfaces, namely a first positioning surface 2 and a second positioning surface 3. The first positioning surface 2 forms a first vertical surface 21 and a first bottom surface 22, and the second positioning surface 3 forms a second vertical surface 31 and a second bottom surface 32.

[0032] When producing a vehicle model, a pair of clamping components 1 move in the sheet metal hole 5 under the drive of the cylinder. When the first vertical surface 21 is in contact with the upper edge 6 of the sheet metal hole and the upper edge of the sheet metal hole 5 is in contact with the first bottom surface 22, the cylinder stops moving. At this time, the crossbeam 4 is clamped and positioned on the first positioning surface 2. Then, VIN marking is performed. After the marking is completed, the cylinder moves back along the original path, causing the pair of clamping components 1 to release the crossbeam 4.

[0033] When producing another model, a pair of clamping components 1 move in the sheet metal hole 5 under the drive of the cylinder. When the second vertical surface 31 is in contact with the upper edge 6 of the sheet metal hole and the upper edge of the sheet metal hole 5 is in contact with the second bottom surface 32, the cylinder stops moving. At this time, the crossbeam 4 is clamped and positioned on the second positioning surface 3. Then, VIN marking is performed. After the marking is completed, the cylinder moves back along the original path, causing the pair of clamping components 1 to release the crossbeam 4.

[0034] Alternatively, the base slopes downwards from the end closest to the facade to the end furthest from the facade.

[0035] Specifically, the bottom surface is provided with an inclination angle, and the upper edge of the sheet metal hole 5 can be made to contact different positions on the bottom surface by adjusting the stroke of the bottom surface extending into the sheet metal hole 5, so as to adjust the positioning height of the crossbeam 4 according to the accuracy error of the crossbeam 4.

[0036] Optionally, the angle of inclination of the bottom surface is 10 degrees to 20 degrees.

[0037] Preferably, the inclination angle of the bottom surface is 15 degrees.

[0038] Optionally, a height difference is provided between the bottom surfaces of different positioning surfaces.

[0039] In this embodiment, the height difference between the first bottom surface 22 and the second bottom surface 32 is set according to the height difference of the upper edge 6 of the sheet metal hole of two different car models, and the inclination angle of the first bottom surface 22 and the second bottom surface 32 is set according to the inclination angle of the upper edge 6 of the sheet metal hole of different car models.

[0040] Optionally, each clamping component 1 is provided with multiple bolt holes 7.

[0041] Specifically, multiple bolt holes 7 are used to clamp the component 1 onto the fixture. In this embodiment, each clamping component 1 is provided with four bolt holes 7, through which hex bolts pass.

[0042] This embodiment also provides a clamp, including:

[0043] Fixture body;

[0044] In this embodiment, the clamping assembly for stamping the vehicle VIN is mounted on the fixture body.

[0045] Optionally, the fixture body is equipped with a cylinder, and a pair of clamping components 1 are connected to each end of the cylinder.

[0046] Optionally, each clamping component 1 is provided with multiple bolt holes 7, and each clamping component 1 is installed on the fixture body through the bolt holes 7.

[0047] Specifically, the clamping assembly of the fixture has at least two pairs of positioning surfaces. Different positioning surfaces are used for different vehicle models. When production switches to different vehicle models, different positioning surfaces are used to position the crossbeam 4 of the VIN to be engraved. There is no need to change the fixture and fixture assembly, which can enable continuous production, reduce labor hours and improve work efficiency.

[0048] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
