Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and more specifically, to a sheet metal part opening device. Background Technology

[0002] Sheet metal parts are products manufactured using sheet metal processing techniques. Their most notable characteristic is that the thickness of any part is consistent. Sheet metal processing includes various operations such as shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming. It is widely used in various industries, particularly in the automotive, communication equipment, medical device, and industrial cabinet industries.

[0003] Currently, after sheet metal parts are formed, they are often drilled using a hole-drilling device according to usage requirements. The hole-drilling device fixes the sheet metal parts with a clamp and then drills holes in the sheet metal parts with a drill rod. However, most existing hole-drilling devices can only drill holes on one side at a time when drilling sheet metal parts. For some sheet metal parts that require drilling on multiple sides, it is necessary to frequently pick up and put down the clamp to adjust the drilling angle, making the hole-drilling process cumbersome and inefficient. Utility Model Content

[0024] Please see Figure 1-3A sheet metal part opening device includes a base plate 1, a Z-axis slide rail module 13 fixedly connected to the top of the base plate 1, a slide block 2 slidably connected to the Z-axis slide rail module 13, a support frame 3 fixedly connected to the top of the slide block 2, clamping plates 4 rotatably connected to the symmetrical side walls of the support frame 3, and a rotary clamping cylinder module 18 fixedly connected to the ends of the two clamping plates 4 that are far apart from each other. Adjustment mechanisms 5 are provided on the slide block 2 and the support frame 3, and the adjustment mechanisms 5 correspond to the two clamping plates 4. A gantry frame 6 is fixedly connected to the top of 1. An X-axis slide rail module 7 is fixedly connected to the top wall of the gantry frame 6. A slide plate 8 is slidably connected to the X-axis slide rail module 7. A Y-axis lifting cylinder 9 is fixedly connected to the slide plate 8. A moving frame 10 is fixedly connected to the output end of the Y-axis lifting cylinder 9. A drilling motor 11 is fixedly connected inside the moving frame 10. A drill bit assembly 12 is provided at the output end of the drilling motor 11, and the drill bit assembly 12 is located on the lower side of the moving frame 10, corresponding to the two clamping plates 4.

[0025] In this embodiment, when drilling holes in the sheet metal part, the sheet metal part is placed in two clamping plates 4, and the output ends of the two rotary clamping cylinder modules 18 rotate 90° and press down to fix the sheet metal part in the two clamping plates 4. The Z-axis slide rail module 13 drives the slide block 2 to move, so that the sheet metal part corresponds with the drill bit assembly 12. The X-axis slide rail module 7 controls the slide plate 8 to move and adjusts the position of the drill bit assembly 12. The drilling motor 11 controls the rotation of the drill bit assembly 12, and the Y-axis lifting cylinder 9 controls the moving frame 10 to move down, so that the drill bit assembly 12 drills holes in the sheet metal part. After drilling one side of the sheet metal part, the angle of the two clamping plates 4 is adjusted synchronously by the adjusting mechanism 5. The two clamping plates 4 drive the angle of the sheet metal part to be adjusted so that different sides of the sheet metal part correspond to the drill bit assembly 12, and the drill bit assembly 12 drills holes again.

[0026] Specifically, the adjusting mechanism 5 includes a worm 51, two rotating rods 52, two worm gears 53, two driving bevel gears 54, and two driven bevel gears 55. The worm 51 is rotatably connected to the support frame 3, and the two rotating rods 52 are rotatably connected to the slide block 2. The two worm gears 53 are respectively fixedly connected to the circumferential surfaces of the two rotating rods 52, and both worm gears 53 mesh with the worm 51. The two driving bevel gears 54 are respectively fixedly connected to the circumferential surfaces of the two rotating rods 52, and the two driven bevel gears 55 are respectively fixedly connected to the ends of the two clamping plates 4 that are far apart, and the two driven bevel gears 55 are respectively located on the symmetrical sides of the support frame 3 and mesh with the two driving bevel gears 54.

[0027] In this embodiment, the worm 51 has two threads in opposite directions on its surface. These two threads mesh with two worm wheels 53. By rotating the worm 51, the two worm wheels 53 drive the two rotating rods 52 to rotate. The two rotating rods 52 drive the two driving bevel gears 54 to rotate. The two driving bevel gears 54 drive the two driven bevel gears 55 to rotate. The two driven bevel gears 55 drive the two clamping plates 4 to rotate in the same direction. The two clamping plates 4 rotate the sheet metal part to adjust the opening position.

[0028] Specifically, the drill bit assembly 12 includes a mounting sleeve 121 and a drill rod 122. The mounting sleeve 121 is fixedly connected to the output end of the drilling motor 11 and is located at the bottom end of the moving frame 10. The drill rod 122 is detachably connected to the mounting sleeve 121 and corresponds to the two clamping plates 4.

[0029] In this embodiment, when drilling holes in sheet metal parts, the drilling motor 11 drives the drill rod 122 to rotate through the mounting sleeve 121. The drill rod 122 drills holes in the sheet metal parts. The drill rod 122 can be disassembled and replaced through the mounting sleeve 121 to meet the requirements of different sizes of openings.

[0030] Specifically, the top of the base plate 1 is fixedly connected to the slide rail assembly 14, and the slide block 2 is slidably connected to the slide rail assembly 14.

[0031] In this embodiment, when the Z-axis slide rail module 13 drives the slide block 2 to move, the slide rail group 14 assists the slide block 2 to move, making the movement of the slide block 2 more stable.

[0032] Specifically, a handle 15 is fixedly connected to one end of the worm gear 51, and the handle 15 is located on one side of the support frame 3.

[0033] In this embodiment, the angle of the sheet metal part is adjusted by rotating the worm gear 51 using the handle 15, making the rotation of the worm gear 51 more convenient.

[0034] Specifically, a protruding plate 16 is fixedly connected to the slide plate 8, and an auxiliary rod group 17 is fixedly connected to the top of the movable frame 10, with the auxiliary rod group 17 movably passing through the protruding plate 16.

[0035] In this embodiment, when the Y-axis lifting cylinder 9 controls the lifting of the moving frame 10, the moving frame 10 drives the auxiliary rod group 17 to slide on the convex plate 16, and the auxiliary rod group 17 makes the lifting of the moving frame 10 more stable.

[0036] Working principle: When drilling holes in sheet metal parts, the sheet metal parts are placed inside two clamping plates 4. The output ends of two rotary clamping cylinder modules 18 rotate 90° and press down, fixing the sheet metal parts inside the two clamping plates 4. The Z-axis slide rail module 13 drives the slide block 2 to move, aligning the sheet metal parts with the drill bit assembly 12. The X-axis slide rail module 7 controls the movement of the slide plate 8 to adjust the position of the drill rod 122. The drilling motor 11 controls the mounting sleeve 121 to drive the drill rod 122 to rotate. The Y-axis lifting cylinder 9 controls the moving frame 10. The drill rod 122 is moved down to drill holes in the sheet metal part. After drilling one side of the sheet metal part, the worm gear 51 is rotated to make the two worm wheels 53 drive the two rotating rods 52 to rotate. The two rotating rods 52 drive the two active bevel gears 54 to rotate, and the two active bevel gears 54 drive the two driven bevel gears 55 to rotate. The two driven bevel gears 55 drive the two clamping plates 4 to rotate in the same direction, so that different sides of the sheet metal part correspond to the drill rod 122. The drill rod 122 is then used to drill holes in the sheet metal part again.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
