Description

[0001] The invention relates to the technical field of automobile metal parts processing, in particular to an automobile metal parts processing and punching system. Background Art

[0002] Automotive metal accessories refer to various metal parts used in the automobile manufacturing process. Among automotive metal accessories, thin-walled metal pipes are more common, especially in lightweight cars to reduce the weight of the car. Such pipes are usually used in exhaust systems, fuel delivery systems, cooling systems, and body structures, etc. These thin-walled metal pipes often need to be drilled in some applications. For example, the fuel delivery pipe, exhaust pipe or the connecting part of the frame structure needs to be installed with sensors, connectors or other components, so it is necessary to drill holes in such pipes.

[0003] However, when drilling holes in automotive thin-walled metal pipe fittings, the thrust of the drill bit is concentrated in a small range. It is difficult for thin-walled materials to evenly disperse this force and lack sufficient support. When subjected to the mechanical force generated during the drilling process, local deformation easily occurs at the drilling site, thus affecting the processing quality of automotive thin-walled metal pipe fittings.

The horizontal wall of the concave plate 31 is symmetrically fixed with an electric push rod 30 installed therethrough.

The upper end of the concave block 16 is fixedly connected to a carrier plate 15.

Rings 20 are fixedly sleeved on the outer walls of the six support columns 14. Springs 21 are fixedly connected between the lower ends of the six rings 20 and the upper end of the carrier plate 15. The six springs 21 are respectively slidably sleeved on the outer walls of the six support columns 14. A locking assembly is provided between the six support columns 14 and the concave block 16.

[0035] The locking assembly includes a motor 22 and six U-shaped blocks 28. The motor 22 is fixedly mounted on the upper surface of the horizontal plate wall of the concave block 16. The output shaft end of the motor 22 is fixedly connected to a cylinder 23. The outer wall of the cylinder 23 is fixedly connected to a plurality of spherical pins 25 around its central annular array. The six U-shaped blocks 28 are fixedly connected to the lower end of the carrier 15 around the central annular array of the carrier 15. The inner walls of the six U-shaped blocks 28 are slidably interspersed with spherical pins 27. The hemispherical ends of the six spherical pins 27 are respectively close to the hemispherical ends of the plurality of spherical pins 25. The other ends of the six spherical pins 27 are fixedly connected to arc-shaped clamping blocks 24. The six arc-shaped clamping blocks 24 are respectively close to the six supporting columns 14. The outer walls of the six spherical pins 27 are slidably sleeved with springs 26. The six springs 26 are respectively fixedly connected between the six U-shaped blocks 28 and the six arc-shaped clamping blocks 24.

[0036] In this embodiment, the tube body 5 (the tube body 5 is a thin-walled metal tube fitting for an automobile) is first placed between the four V-shaped clamping plates 7, and the tube body 5 is located on the outside of the L-shaped rod 12. At this time, the L-shaped rod 12 is also located on the inside of the L-shaped rod 12. Then, the four electric push rods 2 9 are started, and each electric push rod 2 9 drives the V-shaped clamping plate 7 connected to it to move toward the tube body 5. The inner V surfaces of the four V-shaped clamping plates 7 can fit tightly with the outer wall of the tube body 5 and clamp the tube body 5. Then, the two electric push rods 3 30 are started, and the two electric push rods 3 30 can drive the V-shaped seat 6 to move upward until the inner V surface of the V-shaped seat 6 fits tightly with the bottom of the tube body 5. Figure 1 shown.

[0037] Then, the block 10 can be driven upward by the lifting mechanism, and the block 10 can drive the L-shaped rod 12 to move upward, and the L-shaped rod 12 can slide upward on the outer wall of the L-shaped column 13, and the L-shaped rod 12 can drive the concave block 16, the carrier plate 15, the six support columns 14 and other components connected to the concave block 16 to move upward together, until the top ends of the multiple support columns 14 and the inner wall of the tube body 5 are squeezed to a certain extent, then the carrier plate 15 will also squeeze the spring 1 21 connected to the multiple rings 20, and then the motor 22 is started, and the motor 22 can drive the cylinder 23 and the outer wall of the cylinder 23 to move upward. The six spherical pins 1 25 rotate together, and the hemispherical end of each spherical pin 1 25 squeezes and pushes the hemispherical end of the corresponding spherical pin 2 27, so that the six spherical pins 2 27 slide in the corresponding U-shaped blocks 28 toward the corresponding support columns 14, until the six spherical pins 27 can drive the inner arc surfaces of the arc-shaped clamping blocks 24 connected to them to fit tightly with the outer walls of the six support columns 14, and then clamp the six support columns 14, and each arc-shaped clamping block 24 will stretch the spring 2 26 connected to the corresponding U-shaped block 28. On the contrary, when the motor 2 22 drives the cylinder 23 to flip, then under the action of the spring 2 26, each arc-shaped clamping block 24 will leave the outer wall of the corresponding support column 14, loosening the six support columns.

[0038] The center between the six support columns 1 corresponds to the center of the drill rod of the drill tool 1. At this time, the drill tool 1 can be driven downward by the transmission mechanism, and the drill tool 1 can drive the L-shaped column 13 to slide down in the inner wall of the L-shaped rod 12. The drill tool 1 can also drive the drill rod connected to itself to rotate (this is a well-known existing technology and will not be described in detail), so as to drill the outer wall of the tube body 5. At this time, the six support columns 1 can form a uniform support at the drilling location, thereby avoiding local deformation of the drilling location of the tube body 5 and improving the processing quality.

[0039] It is worth mentioning that the transmission mechanism can also drive the drill tool 1 to move left or right, and the drill tool 1 can drive the L-shaped column 13 to move left or right together. The L-shaped column 13 will slide left or right in the block 10, and the L-shaped column 13 can drive the L-shaped rod 12, the concave block 16, the carrier plate 15, the six support columns 14 and other components connected to the concave block 16 to move left or right together, and the top ends of the six support columns 14 will slide on the inner wall of the tube body 5. That is to say, when the drill tool 1 moves left or right to drill other holes on the tube body 5, the six support columns 14 always move synchronously and form uniform support at the drilling location, thereby realizing fast and real-time support for drilling holes at different positions.

[0040] It should be noted that the tube bodies 5 of different radii can be clamped by the four V-shaped clamping plates 7, and the height of the V-shaped seat 6 is controlled by two electric push rods 30, so the V-shaped seat 6 can also fit the bottom of the outer wall of the tube bodies 5 of different radii, and the block 10, L-shaped rod 12, concave block 16, carrier plate 15, six support columns 14 and other components connected to the concave block 16 are controlled in height by the lifting mechanism, and the six support columns 14 are elastically connected to the carrier plate 15 through the ring 20 and the spring 21, so the top ends of the six support columns 14 can fit tightly on the inner wall of the tube bodies 5 of different radii, thereby adapting to the support of the drilled holes of the tube bodies 5 of different radii.

[0041] Example 2: Please refer to Figure 2 , Figure 3 and Figure 6 This embodiment further explains Example 1. The interference mechanism includes two L-shaped blocks 19. The two L-shaped blocks 19 are symmetrically fixedly connected to the outer wall of the L-shaped rod 12 away from the block 10. A connecting block 29 is rotatably connected between the two L-shaped blocks 19. A motor 18 is fixedly installed on the side wall of one of the L-shaped blocks 19. The output shaft end of the motor 18 movably passes through the L-shaped block 19. The output shaft end of the motor 18 is fixedly connected to the block 10, and the side wall of the connecting block 29 is fixedly connected to the support rod 17.

[0042] In this embodiment, the two L-shaped blocks 19 are connected to the L-shaped rod 12 and move with it, so the connecting block 29, the motor 18 and the support rod 17 will also move together, and move up to the top of the six support columns 14 to fit closely with the inner wall of the tube body 5, and after the six support columns 14 are locked, the motor 18 is started at this time, and the motor 18 can drive the connecting block 29 between the two L-shaped blocks 19 to rotate, and the connecting block 29 can drive the support rod 17 to rotate downward until the bottom end of the support rod 17 contacts the inner wall of the tube body 5. At this time, under the support of the support rod 17, a supporting point is added, and the supporting point is close to the six support columns 14, so that the six support columns 14 are more stable. When the L-shaped rod 12 moves left or right, the bottom end of the support column 14 will also slide on the inner wall of the tube body 5.
