[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0024] The specific technical solution of this utility model is as follows:

[0025] In one specific embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a quick positioning punching fixture, including a work platform 1 and a punching plate 2 located above the work platform 1;

[0026] The top of the work platform 1 is provided with a positioning plate 3, and the top of the positioning plate 3 is provided with multiple positioning blocks 4. The multiple positioning blocks 4 form a pre-positioning space for placing automotive parts 5. A movable clamping block 6 is provided on one side of the pre-positioning space. The movable clamping block 6 is slidably connected to the top of the positioning plate 4 through a slide groove. The top of the work platform 1 is provided with a drive cylinder 7, and the output shaft of the drive cylinder 7 is fixedly connected to the movable clamping block 6.

[0027] The bottom of the punching plate 2 is provided with a mounting plate 8. The bottom of the mounting plate 8 is provided with a round hole punching assembly and a round angle punching assembly. The round hole punching assembly includes a plurality of round hole punches 9, which are used to punch and form round holes on the automotive part 5. The round angle punching assembly includes a plurality of round angle punches 10, which are used to punch and form round angles at the corners of the automotive part 5.

[0028] The above solution is as follows: When using the quick positioning punching fixture provided by this utility model, the car part 5 is first placed into the predetermined positioning space by manual or robotic arm. The drive cylinder 7 is extended and the movable clamping block 6 is moved until the movable clamping block 6 abuts against one side of the car part 5. The car part 5 is clamped and fixed by the movable clamping block 6 and the positioning block 4 located on the other side of the car part 5. Then, the punching plate 2 is driven to press down. The punching plate 2 drives the round hole punching component and the R-angle punching component to press down through the mounting plate 8, so that the round hole punching component and the R-angle punching component form multiple round holes and multiple R-angles on the car part 5 respectively. After completion, the punching plate 2 is driven to reset and the drive cylinder 7 is controlled to retract so that the movable clamping block 6 releases the car part 5. The processed car part 5 is then taken out by manual or robotic arm.

[0029] In another specific embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the bottom of the mounting plate 8 is provided with four guide posts 11 arranged in a rectangle, and the positioning plate 3 is provided with four guide holes 12 corresponding to the guide posts 11.

[0031] In another specific embodiment, such as Figure 1 As shown, the punching plate 2 is connected to the punching drive mechanism.

[0032] The above solution is adopted: the punching plate 2 is driven to move by the punching drive mechanism.

[0033] In another specific embodiment, such as Figure 2 and Figure 3 As shown, there are four R-angle punches 10, which correspond to the four corners of the car part 5 respectively.

[0034] The above solution is adopted so that R-angles can be formed at the four corners of automotive part 5.

[0035] In another specific embodiment, such as Figure 1 As shown, the positioning plate 3 is provided with through holes adapted to each punch, and the working platform 1 is provided with a discharge hole communicating with the through holes.

[0036] The above solution allows the punching waste to fall through the through holes and the discharge holes.

[0037] In another specific embodiment, such as Figure 1 As shown, a base 13 is provided below the working platform 1, and a support plate 14 is fixedly connected between the base 13 and the working platform 1. A waste collection box 15 corresponding to the material drop hole is provided on the top of the base 13.

[0038] The above solution enables the unified collection of punching waste.
