[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] like Figure 1-5 As shown, a guide arm airbag hole forming machine includes a frame 1, on which are mounted a punching machine 2, a first-level telescopic cylinder 3, a side positioning telescopic cylinder 4, a pressing oil cylinder 15, and a mounting plate 5. The output end of the first-level telescopic cylinder 3 is mounted with a second-level telescopic cylinder 6, the output end of the second-level telescopic cylinder 6 is fixed with a push claw 7, and two guide plates 8 are fixed on both sides of the push claw 7. The mounting plate 5 is provided with a coiled ear block 9 and a bottom support block 10, and at least two side blocks 11 are fixed to the side of the bottom support block 10, and at least two push rods 12 are fixed to the output end of the side positioning telescopic cylinder 4.

[0026] The frame 1 is in a U-shaped structure, and the driving end of the punching machine 2 is installed through the top of the U-shaped structure of the frame 1. The punching table of the punching machine 2 is located inside the frame 1. The first-level telescopic cylinder 3 is located outside the side of the frame 1. The output end of the second-level telescopic cylinder 6 extends through the frame 1 to the inside of the frame 1. The mounting plate 5 is located on the frame 1 between the punching machine 2 and the first-level telescopic cylinder 3. The side positioning telescopic cylinder 4 is located on the frame 1 on the side of the bottom support block 10, and the clamping cylinder 15 is located directly above the bottom support block 10.

[0027] The output end of the secondary telescopic cylinder 6 is provided with a vertical slide 14, and the rear side of the push claw 7 is slidably connected to the slide 14, and the push claw 7 is bolted to the slide 14. The slide 14 in this embodiment is a commonly used detachable slide 14, which is composed of two bilaterally symmetrical clamping plates and a vertical plate. Both clamping plates have protrusions, and the two clamping plates are bolted to the vertical plate to form a closed slide 14. The shape of the rear side of the push claw 7 matches the shape of the slide 14. By opening an internal thread hole in the push claw 7, and then threading the push claw 7 with a bolt, and the tail of the bolt abuts against the vertical plate, the push claw 7 can be fixed in the slide 14. When the position needs to be adjusted, the push claw 7 is made to slide in the slide 14 by turning the bolt.

[0028] The working end of the front side of the push claw 7 is an inverted L-shaped structure as a whole. The bottom of the horizontal side of the L-shaped structure of the push claw 7 has an upward inclined surface for abutting against the top of the curled ear end of the guide arm 13, and the vertical side of the L-shaped structure of the push claw 7 has an upward inclined surface for abutting against the bottom of the curled ear of the guide arm 13.

[0029] The two guide pieces 8 are located on both sides of the push claw 7 in the horizontal direction. The guide pieces 8 have an outward bend to play a guiding role, so that the curled ear end of the guide arm 13 can more easily enter between the two guide pieces 8. The distance between the two guide pieces 8 is the width of the guide arm 13.

[0030] The ear clamping block 9 is located at one end of the mounting plate 5 close to the first-stage telescopic cylinder 3. The ear clamping block 9 is L-shaped and has an inclined surface. The inclined surface of the ear clamping block 9 faces the push claw 7 to form a clamping connection with the push claw 7 for the ear of the guide arm 13.

[0031] The bottom support block 10 is located at the end of the mounting plate 5 near the punching machine 2. The top surface of the bottom support block 10 is lower than the height of the punching table of the punching machine 2. The side clamping block 11 is located opposite the side positioning telescopic cylinder 4. A step-like structure is formed between the bottom support block 10 and the punching table of the punching machine 2. The bend of the guide arm 13 is located here, so that the end of the guide arm 13 where the airbag hole is to be processed is located on the punching table.

[0032] The working principle of this utility model is:

[0033] During use, the guide arm 13 is adjusted to its proper posture by a six-axis robot and then placed on the ear clamping block 9 and the bottom support block 10. The first-level telescopic cylinder 3 is extended so that the ear end of the guide arm 13 is clamped between the two guide plates 8 and the push claw 7. The second-level telescopic cylinder 6 is extended to push the guide arm 13 so that the bottom of the ear end of the guide arm 13 abuts against the ear clamping block 9. The bend of the guide arm 13 abuts against the side of the punching table of the punching machine 2. At the same time, the side positioning telescopic cylinder 4 is extended and pushed from the side of the guide arm 13 so that the other side of the guide arm 13 abuts against the side clamping block 11, thereby quickly completing the positioning of the guide arm 13. At this time, the pressing cylinder 15 is extended to press the guide arm 13 tightly against the bottom support block 10, thereby fixing the guide arm 13. The punching machine 2 starts working and punches the airbag hole in one go. Then the first-stage telescopic cylinder 3, the second-stage telescopic cylinder 6, the side positioning telescopic cylinder 4, and the pressing oil cylinder 15 all retreat, and the six-axis robot takes out the guide arm 13, thereby completing the shaping work of the airbag hole of the guide arm 13.

[0034] The above-described embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention.
