Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and more specifically to a drilling device for automotive parts processing. Background Technology

[0002] Automotive parts, also known as auto components, auto parts, or auto spare parts, refer to the components that make up the various units of a car and all consumable materials that serve the car. They are characterized by a wide variety, complex substitutes, complex identification systems, and rapid price fluctuations. During the manufacturing process, some automotive parts are often drilled to facilitate assembly or other uses.

[0003] Currently, when drilling holes in automotive parts, it is usually necessary to use a jig to hold and fix them. If both sides of an automotive part need to be drilled, the worker needs to manually remove the automotive part from the jig, flip the part over, and then use the jig to hold and fix it. This method wastes a lot of time, resulting in low efficiency in drilling holes on both sides of automotive parts, which needs to be improved. Utility Model Content

All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: like Figure 1-7As shown, a drilling device for machining automotive parts includes a drilling table 1, a positioning frame 2 above the drilling table 1, a rectangular automotive part 5 inside the positioning frame 2, a drill bit 493 above the rectangular automotive part 5, a fixing frame 4 above the drilling table 1, connecting brackets 41 fixedly installed at the four corners of the bottom of the fixing frame 4, the bottom end of the connecting brackets 41 fixedly installed on the top of the drilling table 1, a positioning plate 43 inside the fixing frame 4, a first electric telescopic rod 42 fixedly installed in the middle of the right side of the fixing frame 4, the telescopic end of the first electric telescopic rod 42 extending into the interior of the fixing frame 4 and fixedly installed in the middle of the right side of the positioning plate 43, two straight rods 44 symmetrically fixedly installed inside the fixing frame 4, the interior of the positioning plate 43 symmetrically slidingly sleeved on the outer wall of the two straight rods 44, a low-speed motor 45 fixedly installed on one side of the inner wall of the positioning plate 43, and a second screw fixedly installed at the output end of the low-speed motor 45 through a coupling. Rod 46, one end of screw 46 is rotatably mounted on the other side of the inner wall of positioning plate 43 via bearing. Positioning block 47 is threadedly connected to the outer wall of screw 46. The outer wall of positioning block 47 is slidably connected to the inside of positioning plate 43. Electric telescopic rod 48 is fixedly mounted at the bottom of positioning block 47. Mounting frame 49 is fixedly mounted at the telescopic end of electric telescopic rod 48. Fixing plate 481 is fixedly mounted on the outer wall of electric telescopic rod 48. Two guide rods 482 are symmetrically fixedly mounted on the top of mounting frame 49. The outer wall of guide rod 482 is slidably connected to the inside of fixing plate 481. Drilling motor 491 is fixedly mounted inside mounting frame 49. The output end of drilling motor 491 extends to the bottom of mounting frame 49 and is fixedly mounted on mounting base 492. The top of drill bit 493 is fixedly mounted on the bottom of mounting base 492. Control panel 6 is fixedly mounted on the right side of the top of drilling table 1.

[0024] In this embodiment, the cooperation of the first electric telescopic rod 42 and the positioning plate 43 facilitates the left and right movement of the drill bit 493. The cooperation of the low-speed motor 45, the second screw 46 and the positioning block 47 facilitates the forward and backward movement of the drill bit 493. The setting of the second electric telescopic rod 48 facilitates the vertical movement of the drill bit 493, thereby making it convenient to adjust the position of the drill bit 493 and to perform drilling processing on different positions of the rectangular automotive part 5.

[0025] Example 2: like Figure 1-7 As shown, two anti-slip plates 22 are symmetrically arranged inside the positioning frame 2. A screw 21 is threadedly connected to the front and rear of the positioning frame 2. A knob is fixedly installed at one end of the screw 21, and the other end of the screw 21 is rotatably installed in the middle of one side of the anti-slip plate 22 through a bearing. A guide rod 23 is slidably connected to both the front and rear sides of the positioning frame 2. One end of the guide rod 23 is fixedly installed in one side of the anti-slip plate 22.

[0026] In this embodiment, by rotating the two No. 1 screws 21, one end of the No. 1 screw 21 can drive the anti-slip clamp 22 and the No. 1 guide rod 23 to move. The No. 1 guide rod 23 facilitates the horizontal guidance of the anti-slip clamp 22. The movement of the two anti-slip clamps 22 facilitates the clamping and fixing of the rectangular car part 5 inside the positioning frame 2.

[0027] Example 3: like Figure 1-7 As shown, a first fixing bracket 24 is fixedly installed on the right side of the top of the drilling platform 1, and a second fixing bracket 26 is fixedly installed on the left side of the top of the drilling platform 1. The positioning frame 2 is located between the first fixing bracket 24 and the second fixing bracket 26. A first connecting shaft 253 is rotatably installed inside the first fixing bracket 24 via a bearing. The left end of the first connecting shaft 253 is fixedly installed in the middle of the right side of the positioning frame 2. A second connecting shaft 27 is rotatably installed inside the second fixing bracket 26 via a bearing. The right end of the second connecting shaft 27 is fixedly installed in the middle of the left side of the positioning frame 2. The outer walls of both the first connecting shaft 253 and the second connecting shaft 27 are fixed. A limiting slider 254 is fixedly installed. A semi-circular limiting groove 241 is opened on one side of both the first fixed frame 24 and the second fixed frame 26. The outer wall of the limiting slider 254 is slidably connected to one side inside the semi-circular limiting groove 241. A protective cover 25 is fixedly installed on the right side of the first fixed frame 24. A drive motor 251 and a worm gear reducer 252 are fixedly installed inside the protective cover 25. The output end of the drive motor 251 is fixedly installed on the input end of the worm gear reducer 252 through a coupling. The output end of the worm gear reducer 252 is fixedly installed on the right end of the first connecting shaft 253 through a coupling.

[0028] In this embodiment, when the output end of the drive motor 251 drives the worm gear reducer 252 to rotate clockwise, the worm gear reducer 252 also drives the first connecting shaft 253 to rotate. At this time, the first connecting shaft 253 drives the limiting slider 254 to slide to the other side inside the semi-circular limiting groove 241. The semi-circular limiting groove 241 limits the limiting slider 254, so that the first connecting shaft 253 can only rotate half a turn. The first connecting shaft 253 simultaneously drives the positioning frame 2, the rectangular car part 5 and the second connecting shaft 27 to rotate half a turn, which can realize the flipping of the rectangular car part 5, which is convenient for subsequent processing of the reverse side of the rectangular car part 5. When the output end of the drive motor 251 drives the worm gear reducer 252 to rotate counterclockwise, the first connecting shaft 253, the limiting slider 254, the positioning frame 2, the rectangular car part 5 and the second connecting shaft 27 can be driven to rotate half a turn in the opposite direction in the same way.

[0029] Example 4: like Figure 1-7As shown, a support plate 3 is provided above the drilling table 1. The bottom of the rectangular automotive part 5 overlaps the top of the support plate 3. A hydraulic rod 31 is fixedly installed in the middle of the bottom of the drilling table 1. The telescopic end of the hydraulic rod 31 extends to the top of the drilling table 1 and is fixedly installed in the middle of the bottom of the support plate 3. Two second guide rods 32 are slidably sleeved inside the drilling table 1. The top ends of the two second guide rods 32 are fixedly installed on both sides of the bottom of the support plate 3.

[0030] In this embodiment, the hydraulic rod 31 facilitates the vertical movement of the support plate 3. The support plate 3 can also drive the second guide rod 32 to move vertically. The second guide rod 32 can guide the support plate 3 vertically, and the movement of the support plate 3 facilitates the support of the rectangular automotive part 5 being drilled.

[0031] In summary, as Figure 1-7As shown, this drilling device for processing automotive parts, in use, first places a rectangular automotive part 5 inside the positioning frame 2 and supports it with a support plate 3. Then, rotate the first screw 21 on both sides of the positioning frame 2. The first screw 21 drives the anti-slip clamp 22 and the first guide rod 23 to move, causing the two anti-slip clamps 22 to clamp the two sides of the rectangular automotive part 5, facilitating the limiting of the rectangular automotive part 5. Then, the output end of the low-speed motor 45 drives the second screw 46 to rotate. The second screw 46 drives the positioning block 47 to slide back and forth inside the positioning plate 43. The positioning block 47 is connected to the second electric telescopic rod 48... The mounting frame 49, drilling motor 491, and mounting base 492 drive the drill bit 493 to move, facilitating adjustment of the drill bit 493's front-to-back position during drilling. The telescopic end of the first electric telescopic rod 42 drives the positioning plate 43 to slide on the outer wall of the two straight rods 44. The positioning plate 43 also drives the drill bit 493 to move left and right, further facilitating adjustment of its left-to-right position during drilling. The telescopic end of the second electric telescopic rod 48 drives the mounting frame 49 to move. The top of the mounting frame 49 and the outer wall of the third guide rod 482 slide vertically downwards inside the fixed plate 481. At this time, the mounting frame 49 drives the drilling motor 491 and mounting base 492 to move. 92 and drill bit 493 move downwards to facilitate height adjustment of drill bit 493. The output end of drilling motor 491 drives mounting base 492 and drill bit 493 to rotate. Drill bit 493 can be used to drill holes on the surface of rectangular automotive part 5. When drilling is required on the reverse side of rectangular automotive part 5, drill bit 493 is first driven upwards by the telescopic end of electric telescopic rod 48, and then the support plate 3 is driven downwards by the telescopic end of hydraulic rod 31. At this time, the cooperation of drive motor 251 and worm gear reducer 252 drives first connecting shaft 253 to rotate, and first connecting shaft 253 drives limit switch. The slider 254 slides to the other side inside the semi-circular limiting groove 241. The semi-circular limiting groove 241 limits the slider 254, so that the first connecting shaft 253 can only rotate half a turn. The first connecting shaft 253 can simultaneously drive the positioning frame 2, the rectangular car part 5 and the second connecting shaft 27 to rotate half a turn, thereby realizing the flipping of the rectangular car part 5. Then, the extension end of the hydraulic rod 31 drives the support plate 3 and the second guide rod 32 to move upward, and the top of the support plate 3 is placed at the bottom of the rectangular car part 5, which facilitates the support of the rectangular car part 5 and makes it convenient to drill holes on the reverse side of the rectangular car part 5 later.
