Description

Technical Field

[0001] The present invention relates to the technical field of casting drilling fixtures, and specifically to an inclined hole drilling fixture for special-shaped castings of new energy vehicles. Background Art

[0002] Special-shaped castings of new energy vehicles are components made through die-casting processes. With the rapid development of new energy vehicles in recent years, the market scale of special-shaped castings has also increased widely. Compared with conventional parts, the structures of special-shaped castings are more complex. Therefore, specific fixtures are required for the inclined hole machining of such complex special-shaped castings to improve the effectiveness of workpiece drilling.

[0003] Currently, when the special-shaped fixture suspends the fixed casting and actively controls the inclination adjustment between the casting and the drill bit through a movable platform during the drilling operation, there are still certain defects. Affected by the length of the drill bit, when the drill bit is long and directly drills obliquely on the top surface of the inclined casting, abnormal vibrations will occur the moment the long drill bit touches the inclined arm of the workpiece, and in severe cases, abnormal scratches will appear on the inclined arm of the casting.

It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other

[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention.

[0023] The following describes a special-shaped casting inclined hole drilling fixture for a new energy vehicle provided by some embodiments of the present invention in conjunction with the accompanying drawings.

The hole adaptation mechanism 200 is used to adaptively clamp special-shaped castings 100 with different hole diameters. The lateral suspension mechanism 300 is used to provide a suspension platform for the casting side coordination mechanism 400. The casting side coordination mechanism 400 is used to provide a coordination and pressure-increasing support platform for the pressing edge mechanism 500. The pressing edge mechanism 500 is used to adaptively press the inclined arm of the special-shaped casting 100. The drill bit angle adjustment mechanism 600 is used to provide protection against abnormal jitter for a longer drill rod.

[0025] The lateral suspension mechanism 300 includes a ring buckle 310 installed outside the column head 210, a cantilever 320 arranged on the ring buckle 310, a limit frame 330 installed at the top of the cantilever 320, a first screw 340 installed inside the limit frame 330, and a backing plate 350 movably installed at the bottom end of the first screw 340; The top of the ring buckle 310 is provided with two clamping plates, and a first stud 3101 is arranged inside the two clamping plates. One end of the first stud 3101 penetrating to the outside of the cantilever 320 is provided with a nut; The casting side coordination mechanism 400 includes an outer frame 410 arranged on the lateral suspension mechanism 300, two groups of pressing components 420 movably installed on the outer frame 410, a spring washer 430 arranged on the two groups of pressing components 420, and a side margin adaptation component 440 arranged inside the two groups of pressing components 420; The pressing component 420 includes a base 421 movably installed on the outer frame 410, two first guide rods 424 installed at the inner end of the base 421, and two second guide rods 425 installed at the outer end of the base 421; A second screw 422 is installed in the middle of the base 421, and a spring 423 is connected to the gasket at the bottom end of the second screw 422; The spring washer 430 is movably installed outside the first guide rod 424; A ring gasket 426 is installed at the bottom end of the second guide rod 425; The margin adaptation component 440 includes a limit cover 443 installed at the bottom end of the first guide rod 424, a reinforcing sleeve 441 arranged at the bottom end of the limit cover 443, and an inner ring rail 442 arranged inside the reinforcing sleeve 441; An annular chute is provided on the inner wall of the inner ring rail 442; Vertical grooves are evenly distributed on the inner wall of the limit cover 443; The edge pressing mechanism 500 includes a plurality of rubber pads 550, and a first beam plate 510, a second beam plate 520, a third beam plate 530, and a fourth beam plate 540 arranged inside the margin adaptation component 440; Second studs 570 are arranged inside the first beam plate 510, the second beam plate 520, the third beam plate 530, and the fourth beam plate 540, nuts 580 installed on the threaded sections of the second studs 570, compression springs 590 arranged at the inner ends of the second studs 570, and end heads 560 arranged outside the second studs 570.

[0026] The stud head 210 is pre-installed on the machine tool until the stud head 210 and two pre-pressure inner pads 240 are exposed. Then, the selected special-shaped casting 100 is installed outside the two pre-pressure inner pads 240. Then, the hexagonal end of the outer end of the boosting lead screw 270 is adjusted by a wrench. As the boosting lead screw 270 rotates clockwise and extends outward, the obtained chuck 280 for traction will push the two traction frames 290 to turn outward until the combined pre-pressure inner pads 240 and the chip removal bin 250 are adapted to and tightly press the inner wall of the special-shaped casting 100. When the special-shaped casting 100 is fixed, the nuts on the two clamping plates at the top of the ring buckle 310 can be adjusted, and then the cantilever 320 after turning over is locked. At this time, the first beam plate 510, the second beam plate 520, the third beam plate 530, and the fourth beam plate 540 that actively apply downward pressure can approach the side wall of the special-shaped casting 100 until the plurality of rubber pads 550 arranged in a circumferential uniform distribution are adapted to the inclined arms of the special-shaped casting 100 and are gradually and hierarchically pressed; As the drill bit extends along the inside of the limit cover 443 and passes through the holes in the control support plate 640, finally the bottom end of the drill bit will obliquely drill the inclined arm at the top of the special-shaped casting 100. The first beam plate 510, the second beam plate 520, the third beam plate 530, and the fourth beam plate 540 after being gradually and hierarchically separated can cooperate with the control support plate 640 to provide stability enhancement protection for the drill bit. When the waste inside the special-shaped casting 100 falls along the holes, the waste will be effectively stored in the chip removal bin 250. Under the radiation of the shock wave during drilling, the waste in the inner cavity of the chip removal bin 250 can be discharged outward from the holes inside the stud head 210 under the radiation of the shock wave.

[0027] Example 2: Combined with Figures 2 to 4As shown, on the basis of Embodiment 1, the hole casting adaptation mechanism 200 includes two pre-pressure inner pads 240 arranged inside the special-shaped casting 100, a chip removal bin 250 arranged on the inner wall of the pre-pressure inner pad 240, a stud 210 movably installed outside the two pre-pressure inner pads 240, a screw sleeve 260 installed in the middle of the outer end of the stud 210, a boosting lead screw 270 arranged inside the screw sleeve 260, a chuck 280 movably installed at the inner end of the boosting lead screw 270, and two traction frames 290 movably installed at both ends of the chuck 280; Symmetrically distributed chutes are provided at the top and bottom of the inner end of the stud 210, and a sealing plate 220 is arranged outside the chutes.

[0028] Preferably, the sealing plate 220 is installed on the outer wall of the stud 210 through bolts. Among them, an insertion block is arranged at the bottom of the sealing plate 220, and the insertion block is adaptively clamped in the chute at the inner end of the stud 210 according to actual use requirements.

[0029] A vertical rod 230 is installed inside the sealing plate 220; A first slider 2401 is arranged at the inner end of the pre-pressure inner pad 240, and the first slider 2401 is adaptively penetrated into the chute at the inner end of the stud 210, and the vertical rod 230 is adaptively penetrated into the first slider 2401; A foot pad is installed in the middle of the inner side of the chip removal bin 250, and one end of the traction frame 290 away from the chuck 280 is movably installed on the foot pad; An anti-slip cushion layer is arranged on the outer wall of the pre-pressure inner pad 240.

[0030] Preferably, the inner wall of the chip removal bin 250 is coated with an anti-rust paint layer, and the cavity of the chip removal bin 250 communicates with the holes in the cavity of the stud 210. The notch inside the pre-pressure inner pad 240 is located directly below the hole in the control support plate 640; A column is arranged at one end of the stud 210 away from the pre-pressure inner pad 240, and a hollow hole is opened inside the column. The hexagonal end of the boosting lead screw 270 penetrates into the hole of the column.

[0031] Embodiment 3: Combined with Figure 1 and Figure 8 As shown, on the basis of Embodiment 1, the drill bit angle adjustment mechanism 600 includes two guiding frames 610 arranged on two groups of outer frames 410, two supporting rods 620 movably installed inside the two guiding frames 610, a control support plate 640 installed at the bottom of the two supporting rods 620, two second sliders 650 movably installed on the studs at both ends of the control support plate 640, and a locking bolt 630 arranged on the stud at the top of the supporting rod 620; The guiding frame 610 is composed of a U-shaped bracket and a semi-circular arc track, and the U-shaped bracket is installed outside the two first guide rods 424.

[0032] After two guiding frames 610 are installed outside two groups of first guide rods 424, two support rods 620 carried by the two guiding frames 610 can provide sufficiently stable support for the suspended position-control pallet 640 and the inner ring rail 442. After the position-control pallet 640 is finely adjusted in inclination along the two second sliders 650, the drill bit can stably rotate under the inclination support when it extends into the position-control pallet 640, thereby reducing the abnormal vibration phenomenon that occurs when the drill bit contacts the outer wall of the special-shaped casting 100 for a moment.

[0033] Example 4: Combined with Figures 8 to 10 As shown, in the above embodiment, through holes are formed in the first beam plate 510, the second beam plate 520, the third beam plate 530, and the fourth beam plate 540, and the through holes are symmetrically adapted to the vertical grooves on the inner wall of the limit cover 443; The inner end of the second stud 570 is adapted to penetrate into the through hole, and one end of the compression spring 590 is adapted to bear against the inner wall of the limit cover 443.

[0034] Preferably, the number of the first beam plates 510 is two, the number of the second beam plates 520 and the third beam plates 530 is four, and the number of the fourth beam plates 540 is six, and the first beam plates 510, the second beam plates 520, the third beam plates 530, and the fourth beam plates 540 are all made of stainless steel; Among them, heat-insulating coatings are coated on the inner walls of the first beam plate 510, the second beam plate 520, the third beam plate 530, and the fourth beam plate 540.

[0035] The working principle and usage process of the present invention: The boosting lead screw 270 is pre-adjusted to rotate. At this time, the chuck 280 movably installed at the inner end of the boosting lead screw 270 will pull the two traction frames 290 to extend under constant pressure until the two pre-pressure inner pads 240 expand outwards and tighten the selected part of the inner wall of the special-shaped casting 100. At this time, the two pre-pressure inner pads 240 can provide a pressure-bearing platform for effectively drilling the special-shaped casting 100; Use fastening bolts to lock the cantilever 320 after angle adjustment between two clamping plates at the top of the loop 310. At this time, the casting side coordination mechanism 400 suspended at the top of the cantilever 320 can press the flanging mechanism 500 against the side of the special-shaped casting 100 until components such as the first beam plate 510, the second beam plate 520, the third beam plate 530, and the fourth beam plate 540 evenly distributed in a circle fit against the side wall at the top of the special-shaped casting 100. At this time, multiple rubber pads 550 evenly distributed at the bottom of the first beam plate 510, the second beam plate 520, the third beam plate 530, and the fourth beam plate 540 can be pre-pressed on the special-shaped casting 100. Then, adjust the hexagonal end at the top of the first screw 340. As the first screw 340 rotates clockwise, the backing plate 350 movably installed at the bottom of the first screw 340 will be pushed by the thrust and apply downward pressure to the outer frame 410. And the above-mentioned multiple rubber pads 550 evenly distributed in a circle will be pressed tightly on the selected part at the top of the special-shaped casting 100 under the continuous pressure; As the multiple rubber pads 550 change in layers in cooperation with the special-shaped structure of the outer wall of the special-shaped casting 100, the multiple first beam plates 510, second beam plates 520, third beam plates 530, and fourth beam plates 540 applying reverse pressure will be forced to stretch upward. At the same time, adjust the instantaneous rotation of the two second screws 422, and the two springs 423 will be pushed by the two second screws 422 and pressed downward. At this time, the elastic washers 430 arranged at the bottom of the two springs 423 can limit the tops of the multiple first beam plates 510, second beam plates 520, third beam plates 530, and fourth beam plates 540 after gradual change and layering to provide a stable reaction support platform. Then, use a wrench to tighten the multiple nuts 580 clockwise until the multiple first beam plates 510, second beam plates 520, third beam plates 530, and fourth beam plates 540 after layering and gradual change are fixed on the outer wall of the limit cover 443; Then loosen the two locking bolts 630, and then control the two struts 620 to tilt and turn along the annular slideways of the two guiding frames 610 until the position control support plate 640 rotates along the two second sliders 650. At this time, the holes inside the position control support plate 640 can provide a suspended support platform for guiding drilling at the top position of the special-shaped casting 100. When the angle of the position control support plate 640 is selected, the two locking bolts 630 can be tightened. When the drill rod drills obliquely against the top position of the special-shaped casting 100 along the limit cover 443 and the holes of the position control support plate 640, the waste chips drilled out inside the special-shaped casting 100 will fall into the inner cavity of the chip removal bin 250, and the inner cavity of the chip removal bin 250 is connected to the holes inside the column head 210. At this time, the waste chips can be effectively released; At this time, the multiple first beam plates 510, second beam plates 520, third beam plates 530, and fourth beam plates 540 that are evenly distributed and gradually stratified and then pressed on the special-shaped casting 100 can cooperate with the limiting cover 443 to provide a sufficiently compressive and stable bearing platform for the operation of the drill pipe, thereby avoiding the problem of abnormal jitter during the operation of the drill pipe under pressure due to the long length of the drill pipe, and ensuring the accuracy of the drilling control position at the top of the special-shaped casting 100; Therefore, this fixture can provide anti-error and misalignment protection for drilling the outer wall of the automotive special-shaped casting 100.

[0036] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present invention. The scope of the present invention is defined by the claims and their equivalents.
