Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle charging base panel processing technology, and in particular to a part drilling guide device. Background Technology

[0002] Existing new energy vehicle charging pads, such as Figure 5 As shown, it includes a base 204, a contoured flange 205, two left connecting plates 206 fixedly connected to one side of the annular flange, and two right connecting plates 202 fixedly connected to the other side of the annular flange. The base is provided with a socket 203 adapted to the charging plug of a new energy vehicle. The contoured flange is provided along the edge of the socket. The two left connecting plates are set up and down, and the two right connecting plates are set up and down. Mounting holes 207 are provided on both the left and right connecting plates.

[0003] When the existing charging base panel is first manufactured, the left and right connecting plates do not have mounting holes, which need to be drilled. During drilling, the charging base panel is vertically fixed using a tooling, and the drill rod of the drilling device penetrates downwards through the two left connecting plates to drill mounting holes (the same method is used to process the right connecting plate). Because the distance between the two left connecting plates is relatively large and the length of the drill rod is also relatively long, the lower end of the drill rod is prone to shaking when drilling directly downwards, resulting in the drilling of mounting holes that are off-center and have a larger diameter than expected. Utility Model Content

[0004] To address the shortcomings of existing drilling methods for charging base panels, such as eccentric mounting holes and excessively large hole diameters, this invention proposes a part drilling guide device to reduce drill rod wobbling and prevent eccentric mounting holes and excessively large hole diameters.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A part drilling guide device includes a base and a support block fixedly connected to the upper side of the base. One side of the support block is provided with a vertically extending extrusion surface. The extrusion surface is provided with a limiting protrusion adapted to the part to be processed. The drilling guide device also includes a locking assembly, two vertically arranged left guide blocks, and two vertically arranged right guide blocks. Both the left and right guide blocks protrude from the extrusion surface and are provided with guide holes adapted to the drill rod through them vertically. The locking assembly is used to lock the part to be processed on the extrusion surface so that the left guide block is located on the upper side of the left connecting plate of the part, and the right guide block is located on the upper side of the right connecting plate of the part.

[0007] With the above settings, after the locking assembly locks the part to be processed, the left connecting plate and the right connecting plate are respectively provided with a left guide block and a right guide block. When the drill rod drills downward, the drill first enters the guide hole and then drills. The left guide block and the right guide block prevent the lower end of the drill rod from shaking, thereby preventing the drilled mounting hole from being eccentric and making the diameter of the mounting hole more accurate.

[0008] Furthermore, the limiting protrusion is provided with a threaded hole, and the locking assembly includes a pressure plate and a first bolt. The pressure plate is arranged parallel to the extrusion surface, and the first bolt passes through the pressure plate and is threadedly connected to the threaded hole. The pressure plate presses the part tightly onto the extrusion surface.

[0009] With the above setup, the first bolt presses the part onto the extrusion surface via the pressure plate.

[0010] Furthermore, the pressure plate is provided with a slot, through which the first bolt passes through the pressure plate. The slot has an opening on the lower side to allow the first bolt to enter and exit.

[0011] The above settings facilitate the assembly and disassembly of the pressure plate.

[0012] Furthermore, the extrusion surface is provided with a first left slot adapted to the left guide block and a first right slot adapted to the right guide block. The left guide block end is provided with a left anti-pull-out groove extending vertically and is inserted into the first left slot. The right guide block end is provided with a right anti-pull-out groove extending vertically and is inserted into the first right slot. The upper side of the support block is provided with a second left slot extending downward to the left anti-pull-out groove and a second right slot extending downward to the right anti-pull-out groove. The drilling guide device also includes a left pin inserted into the second left slot and the left anti-pull-out groove, and a right pin inserted into the second right slot and the right anti-pull-out groove.

[0013] The above settings facilitate the assembly and disassembly of the left and right guide blocks.

[0014] Furthermore, the support block is provided with bolt holes running through its top and bottom, and the drilling guide device also includes a second bolt, which passes through the bolt holes and is threadedly connected to the base.

[0015] With the above setup, the support block is fixed to the base by the second bolt.

[0016] Furthermore, a left air intake hole and a right air intake hole are provided on the extrusion surface. The left air intake hole is located between two left guide blocks, and the right air intake hole is located between two right guide blocks. The left air intake hole and the right air intake hole extend to the back of the support block and are connected to the air pipe, which is used to connect to the air extraction device.

[0017] With the above configuration, the air extraction device can absorb debris through the air pipe, preventing debris generated during drilling from entering the guide hole on the lower side.

[0018] Furthermore, the left air intake is positioned close to the left guide block, and the right air intake is positioned close to the right guide block. Attached Figure Description

[0024] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0025] like Figures 1 to 4 As shown, a part drilling guide device includes a base 3 and a support block 4 fixedly connected to the upper side of the base 3. A vertically extending extrusion surface 5 is provided on one side of the support block 4. A limiting protrusion 6 adapted to the part 200 to be processed is provided on the extrusion surface 5. The drilling guide device also includes a locking assembly 7, two vertically arranged left guide blocks 8, and two vertically arranged right guide blocks 9. Both the left guide blocks 8 and the right guide blocks 9 protrude from the extrusion surface 5 and are provided with guide holes 10 adapted to the drill rod through them vertically. The locking assembly 7 is used to lock the part 200 to be processed on the extrusion surface 5 so that the left guide block 8 is located on the upper side of the left connecting plate of the part 200, and the right guide block 9 is located on the upper side of the right connecting plate 202 of the part 200.

[0026] With the above settings, after the locking assembly 7 locks the part 200 to be processed, the left connecting plate and the right connecting plate 202 are respectively provided with a left guide block 8 and a right guide block 9. When the drill rod drills downward, the drill first enters the guide hole 10 and then drills. The left guide block 8 and the right guide block 9 prevent the lower end of the drill rod from shaking, thereby preventing the drilled mounting hole from being eccentric and making the diameter of the mounting hole more accurate.

[0027] The part 200 to be processed in this application is specifically a charging base panel for new energy vehicles, with a structure as described in the background art. Figure 5 The details are omitted here. The drilling guide device of this application is located below the drilling machine, which is a drilling machine with a drill rod that moves vertically up and down. The part 200 to be processed is placed on the limiting protrusion 6. The outer periphery of the limiting protrusion 6 fits against the inner wall of the insertion hole 203 of the part 200. Because the insertion hole of the part 200 is basically D-shaped, the part 200 cannot rotate on the limiting protrusion 6. At this time, the two left guide blocks 8 are respectively located on the upper side of the two left connecting plates of the part 200, and the two right guide blocks 9 are respectively located on the upper side of the two right connecting plates 202 of the part 200. The locking assembly 7 is used to press the part 200 onto the pressing surface 5 to fix the part 200. Figure 3As shown; during drilling, the drill rod is initially positioned directly above the left guide block 8. The drill rod moves downwards, and its lower end first enters the guide hole 10 of the upper left guide block 8. Since the diameter of the guide hole 10 is approximately equal to the outer diameter of the drill rod, the lower end of the drill rod will not wobble. The drill rod continues to move downwards, drilling mounting holes on the upper left connecting plate. As the drill rod continues to move downwards, its lower end enters the guide hole 10 of the lower left guide block 8. Similarly, the stability of the drill rod increases under the action of the lower left guide block 8, and finally, mounting holes are drilled on the lower left connecting plate. At this point, the drilling of mounting holes on the two left connecting plates of part 200 is completed. The drill rod moves upwards and is pulled out from the two left guide blocks 8. The drilling machine moves laterally to above the right guide block 9 under the action of the lateral power mechanism such as the track, and then drills mounting holes on the two right guide blocks 9 according to the above method.

[0028] As one implementation, the limiting protrusion 6 is provided with a threaded hole, and the locking assembly 7 includes a pressure plate 71 and a first bolt 72. The pressure plate 71 is arranged parallel to the extrusion surface 5, and the first bolt 72 passes through the pressure plate 71 and is threadedly connected to the threaded hole. The pressure plate 71 presses the part 200 onto the extrusion surface 5.

[0029] With the above setup, the first bolt 72 presses the part 200 onto the extrusion surface 5 via the pressure plate 71.

[0030] The pressure plate 71 in this application is basically a horizontally extending rectangular plate. After the first bolt 72 is tightened, as... Figure 3 As shown, the pressure plate 71 presses the left and right sides of the part 200.

[0031] As one implementation, the pressure plate 71 is provided with a slot 73, through which the first bolt 72 passes through the pressure plate 71. The slot 73 has an opening on the lower side to allow the first bolt 72 to enter and exit.

[0032] The above settings facilitate the assembly and disassembly of the pressure plate 71.

[0033] The first bolt 72 of this application is loosened, but it is not necessary to completely unscrew the first bolt 72. The pressure plate 71 can be separated from the first bolt 72 upwards. After the part 200 to be processed is put on the limiting protrusion 6, the pressure plate 71 is pressed downwards onto the first bolt 72. The first bolt 72 passes through the upper end of the slot 73. After tightening the first bolt 72, the head of the first bolt 72 presses against the pressure plate 71, and the pressure plate 71 presses the part 200 tightly.

[0034] As one implementation, the extrusion surface 5 is provided with a first left slot 11 adapted to the left guide block 8 and a first right slot 12 adapted to the right guide block 9. The left guide block 8 is provided with a left anti-pull-out groove 13 extending vertically through its end and inserted into the first left slot 11. The right guide block 9 is provided with a right anti-pull-out groove 14 extending vertically through its end and inserted into the first right slot 12. The upper side of the support block 4 is provided with a second left slot 15 extending downward to the left anti-pull-out groove 13 and a second right slot 16 extending downward to the right anti-pull-out groove 14. The drilling guide device also includes a left pin 17 inserted into the second left slot 15 and the left anti-pull-out groove 13, and a right pin 18 inserted into the second right slot 16 and the right anti-pull-out groove 14.

[0035] The above settings facilitate the assembly and disassembly of the left guide block 8 and the right guide block 9.

[0036] When the left guide block 8 of this application is installed, if Figure 2 As shown, the left guide block 8 is inserted into the first left slot 11, the left anti-pull groove 13 is aligned with the first left slot 11, the left pin 17 is inserted downward into the second left slot 15, and the lower end of the left pin 17 is inserted into the left anti-pull groove 13. The outer diameter of the left pin 17, the inner diameter of the second left slot 15, and the inner diameter of the left anti-pull groove 13 are equal. After the left pin 17 is inserted, the left guide block 8 will not wobble. When removing the left guide block 8, the left pin 17 is pulled out to remove the left guide block 8. The disassembly and assembly of the right guide block 9 are similar and will not be described in detail. The left guide block 8 and the right guide block 9 of this application are easy to disassemble and assemble, and it is convenient to replace the left guide block 8 and the right guide block 9 with different guide hole diameters to adapt to drill rods with different outer diameters.

[0037] As one implementation, the support block 4 is provided with bolt holes running through its top and bottom. The drilling guide device also includes a second bolt 19, which passes through the bolt holes and is threadedly connected to the base 3.

[0038] With the above setup, the support block 4 is fixed to the base 3 by the second bolt 19.

[0039] As one implementation, the extrusion surface 5 is provided with a left suction hole 20 and a right suction hole 21. The left suction hole 20 is located between two left guide blocks 8, and the right suction hole 21 is located between two right guide blocks 9. The left suction hole 20 and the right suction hole 21 extend to the back of the support block 4 and are connected to the air pipe 22. The air pipe 22 is used to connect to the air extraction device.

[0040] With the above configuration, the air extraction device can absorb debris through the air pipe 22, preventing the debris generated during drilling from entering the guide hole 10 on the lower side.

[0041] When the drill rod of this application drills a hole in the upper left connecting plate, debris will fall off. The air extraction device sucks away the falling debris through the air pipe 22 and the left suction hole 20, preventing the debris from entering the guide block of the lower left guide block 8, thereby preventing the debris from abrading the lower guide hole 10. The air extraction device is specifically a vacuum cleaner.

[0042] In one implementation, the left air intake 20 is positioned close to the left guide block 8, and the right air intake 21 is positioned close to the right guide block 9.

[0043] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
