It should be noted that, unless otherwise specified, the embodiments and features described herein 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 invention.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of an automatic stamping device for gearbox housings provided by the present invention.

[0024] Example 1: Combination Figures 1 to 8As shown, the present invention provides an automatic stamping device for a gearbox housing, comprising a stamping support mechanism 100, a punching mechanism 200 mounted on the stamping support mechanism 100, a hole position calibration mechanism 300 mounted on the stamping support mechanism 100, and a slope adjustment mechanism 400 mounted within the hole position calibration mechanism 300. The stamping support mechanism 100 is fixed to the worktable by expansion bolts, which facilitates providing an effective support carrier for the punching mechanism 200. The punching mechanism 200 is used to cooperate with the stamping support mechanism 100 to fit and clamp the gearbox housing. The hole position calibration mechanism 300 is used to fit and bear pressure on the bottom part of the gearbox housing to be stamped. The slope adjustment mechanism 400 is used to enhance the bearing protection of the slope at the bottom of the gearbox housing.

[0025] The stamping bearing mechanism 100 includes a load-bearing base plate 110, a load-bearing frame 1102 installed on the load-bearing base plate 110, a support plate 130 provided inside the load-bearing frame 1102, a hexagonal threaded sleeve 1302 movably installed inside the support plate 130, and two support rods 140 movably installed inside the load-bearing frame 1102. A gasket 1401 is installed on the support rod 140, and a first spring 150 is provided outside the support rod 140 to bear pressure between the load-bearing frame 1102 and the gasket 1401. A pressure plate 160 is installed at the top of the support rod 140. Four symmetrically distributed fixing plates 1101 are fixedly installed on both sides of the load-bearing base plate 110, and the fixing plates 1101 have pre-installed holes inside. An inclined discharge plate 120 is fixedly installed between the load-bearing base plate 110 and the load-bearing frame 1102, and the inclined surface of the discharge plate 120 is located directly below the hole calibration mechanism 300. Two combination bolts 1301 are installed inside the support plate 130 and the load-bearing frame 1102; The punching mechanism 200 includes a first lead screw 230 threaded into a hexagonal threaded sleeve 1302 and a limiting rod 2201 inserted into a support plate 130. A crossbeam 220 is fixedly installed at the top of the limiting rod 2201, and the top of the first lead screw 230 is movably installed in the crossbeam 220. Two symmetrically distributed outer frames 210 are fixedly installed at both ends of the crossbeam 220, and a pressure plate 240 is installed at the top of each of the two outer frames 210. A base 250 is fixedly installed inside the two pressure plates 240. A punching part 260 is movably installed inside the base 250, and a reinforcing tension spring 270 is fixedly connected between the punching part 260 and the base 250. Rubber anti-slip layers are fixedly installed on the U-shaped surfaces of the pressure plate 160 and the cover plate 240. The bottom of the punching part 260 has a hollow circular cutting edge, and the top of the punching part 260 has a pressure-bearing column head.

[0026] When in use, use a wrench to reverse the hexagonal threaded sleeve 1302 until the first screw 230 rises in the opposite direction along the inside of the hexagonal threaded sleeve 1302. After rising, the first screw 230, together with the limit rod 2201, will lift the crossbeam 220 until the two outer frames 210 fixed at both ends of the crossbeam 220 carry the two pressure plates 240 and the two load plates 160 to widen the distance. Next, the gearbox housing plate is inserted into the gap between the expanded-spacing pressure plate 240 and the load plate 160 until the gearbox housing plate is pressed against the two load plates 160. Then, the hexagonal threaded sleeve 1302 is rotated clockwise with a wrench. Finally, the first lead screw 230 will descend rapidly along the internal thread hole of the hexagonal threaded sleeve 1302 until the two outer frames 210 and the two pressure plates 240 descend rapidly. The two pressure plates 240, after descending, will work with the two load plates 160 to quickly clamp and fix the gearbox housing plate. During the clamping of the gearbox housing plate, the part to be stamped is adjusted until the punched part 260 is adapted, calibrated and aligned with the part to be stamped on the gearbox housing plate. Then, the external punch is used to apply extrusion pressure to the punched part 260. Finally, the extruded punched part 260 will descend rapidly along the inner cavity of the base 250, and the cutting edge at the bottom of the punched part 260 will perform rapid punching on the gearbox housing plate.

[0027] Example 2: Combination Figures 5 to 7 As shown, based on Embodiment 1, the hole calibration mechanism 300 includes a support tube 310 fixedly installed in the support plate 130. A clamp 3101 is fixedly installed at the top of the support tube 310. A plurality of evenly distributed vertical holes 3102 are opened in the inclined surface of the clamp 3101. A stud 3103 is fixedly installed in the groove on the side of the inclined surface of the clamp 3101. A plurality of evenly distributed built-in support blocks 350 are movably installed in the clamp 3101. A chuck 3504 is fixedly installed on the inner wall of the built-in support block 350. The built-in support block 350 has an overall L-shaped structure. A main shaft 3501 is movably installed in the plate end of the built-in support block 350 that extends to the outside of the clamp 3101. A top support block 3502 is movably installed on the main shaft 3501. An elastic pressure plate 3503 is fixedly installed in the groove at the top of the top support block 3502. An anti-slip rubber pad is provided on the outer surface of the elastic pressure plate 3503. The outer wall of the support tube 310 is provided with a positioning plate 320, and the positioning plate 320 is fixed to the support tube 310 by bolts; A housing 330 is fixedly installed on the support tube 310. A motor 3301 is fixedly installed inside the housing 330. A second lead screw 3302 is fixedly installed on the drive shaft of the motor 3301. The top end of the second lead screw 3302 is adapted to pass through the insertion hole on the inclined surface of the clamp 3101. A main slide 340 is threaded on the second lead screw 3302. The main slide 340 is movably installed on the outside of the support tube 310. Multiple cantilever 3401s are movably connected to the main slide 340. The other end of the cantilever 3401 is movably mounted on the chuck 3504.

[0028] Preferably, the chassis 330 is fixed to the outside of the support tube 310 by two annular clamps, and two symmetrically distributed annular gaskets are fixedly installed on the tube section at the bottom of the support tube 310, while the two annular gaskets are located on the top and bottom surfaces of the bottom plate section of the support plate 130. To enhance the deformation protection of the part of the gearbox housing to be stamped, the motor 3301 is started by the client, and the motor 3301 will drive the second lead screw 3302. Finally, the main slide 340 will rise and fall relative to the second lead screw 3302. As the main slide 340 rises and falls, the multiple cantilever 3401 that are pulled will control the aperture of the multiple built-in support blocks 350 evenly distributed. The multiple top support blocks 3502 and multiple elastic pressure plates 3503 that are horizontally placed above the top of the clamp 3101 will increase the pressure protection range of the bottom of the gearbox housing. As the external punch acts on the top of the punching part 260, the punching part 260, which is pressed down, cooperates with multiple elastic pressure plates 3503 and multiple top support blocks 3502 to perform dual cooperation on the gearbox housing plate. Finally, the punching part 260 can perform rapid punching processing on the gearbox housing plate, further enhancing the integrity of the punching structure of the gearbox housing plate.

[0029] Example 3: Combination Figure 6 and Figure 8 As shown, in the above embodiment, the inclined plane adjustment mechanism 400 includes a third lead screw 420 threadedly installed in the positioning plate 320. A secondary slide 410 is movably installed at the top of the third lead screw 420, and the secondary slide 410 is movably installed outside the support tube 310. A plurality of evenly distributed support rods 430 are fixedly installed inside the secondary slide 410. A pad 440 is installed on the stud 3103. A vertical rod 4401 is fixedly installed inside the pad 440. A second spring 4402 is provided outside the vertical rod 4401. A height adjustment support plate 450 is movably installed outside the vertical rod 4401, and the two ends of the second spring 4402 are respectively pressed against the inner wall of the height adjustment support plate 450 and the clamp 3101. The top of the height adjustment support plate 450 is movably mounted with a card seat 4501, and the plate end of the top of the support rod 430 is movably mounted on the vertical rod 4401, while the plate end of the top of the support rod 430 is pressed against the bottom of the height adjustment support plate 450. A T-shaped slider is fixedly installed at the bottom of the top support block 3502, and a groove is opened at the top of the card holder 4501, with the T-shaped slider fitting through the groove. A slide is provided in the bottom plate end of the built-in support block 350, and the bottom plate end of the height adjustment support plate 450 is adapted to pass through the slide.

[0030] Preferably, the inner walls of the auxiliary slide 410 and the main slide 340 are coated with lubricating oil. A hexagonal spur head is fixedly installed inside the end of the positioning plate 320. After rotating the wheel at the bottom of the third lead screw 420, the third lead screw 420 will move up and down relative to the hexagonal spur head. The rising and falling third lead screw 420 will push the auxiliary slide 410 and multiple support rods 430 to rise and fall synchronously and smoothly. The plate end of the top of the support rod 430 is adapted to penetrate into the vertical hole 3102. After the top plate of the support rod 430 slides relative to the inner cavity of the vertical hole 3102, the vertical rod 4401 located in the middle of the inner cavity of the vertical hole 3102 will provide sufficiently stable guidance and pressure protection for the lifting and lowering of the support rod 430. As the top plate of the support rod 430 is lifted and lowered, the card seat 4501, which is movably installed on the height adjustment support plate 450, will control the top support block 3502 to adjust the relative tilt angle with the main shaft 3501 as the axis, so as to facilitate the quick adaptation to the inclined surface at the bottom of the gearbox housing plate.

[0031] The working principle and usage process of this invention are as follows: First, use a wrench to reverse the hexagonal threaded sleeve 1302. As the hexagonal threaded sleeve 1302 rotates, the first lead screw 230 will be lifted upward along the threaded hole inside the hexagonal threaded sleeve 1302. The crossbeam 220 carries the two outer frames 210 and the two pressure plates 240 upward until a sufficiently large gap is exposed between the two pressure plates 240 and the load plate 160. Then, the gearbox housing plate to be processed is placed in the gap, and the two load plates 160 support the gearbox housing plate. Then, use a wrench to turn the hexagonal threaded sleeve 1302 forward. Finally, the first lead screw 230, the crossbeam 220 and the two pressure plates 240 will work with the two load plates 160 to quickly clamp and fix the gearbox housing plate. During the clamping process, the part of the gearbox housing plate to be punched is adjusted until the part of the gearbox housing plate to be punched is directly below the punched part 260. As the punching mechanism 200 lowers the gearbox housing plate, the inclined surface of the lower surface of the gearbox housing plate moves closer to the evenly distributed multiple elastic pressure plates 3503. Based on the pressure protection range of the bottom of the gearbox housing plate to be punched, the motor 3301 is started by the client. The second lead screw 3302 fixed on the motor 3301 will push the main slide 340 to rise and fall relative to the outer wall of the support tube 310. As the main slide 340 rises, the multiple cantilever 3401 movably connected on the main slide 340 will push the multiple built-in support blocks 350 to expand outward synchronously. Finally, the diameter between the evenly distributed multiple built-in support blocks 350 and the multiple top support blocks 3502 will gradually increase, which will help to increase the pressure-bearing area at the bottom of the gearbox housing plate. The bottom of the gearbox housing plate will be adapted to bear pressure by the expanded multiple elastic pressure plates 3503, further enhancing the pressure protection of the area of ​​the gearbox housing plate to be punched. Meanwhile, the bottom structure of the gearbox housing is complex. To avoid abnormal shaking of the gearbox housing under pressure, which could lead to irregular punching, a rotating wheel at the bottom of the third lead screw 420 is used until the third lead screw 420 rises upward along the inside of the positioning plate 320. Ultimately, the third lead screw 420 pushes the auxiliary slide 410 and the multiple evenly distributed support rods 430 to rise simultaneously. As the top section of the support rods 430 rises smoothly along the inner cavity of the load-bearing frame 1102, the vertical rods 4401 fixed by the pads 440 will... The guide rod 430 rises smoothly, and the top plate of the guide rod 430 continues to rise, which will further raise the height adjustment plate 450 and the bracket 4501. After the bracket 4501 is raised, it will lift the top support block 3502 upward with the main shaft 3501 as the axis. Finally, the multiple evenly distributed top support blocks 3502 will form a funnel-shaped structure. The multiple top support blocks 3502 forming the funnel-shaped structure will further enhance the adaptation and pressure bearing on the inclined or complex surface at the bottom of the gearbox housing plate, avoiding the risk of abnormal shaking during the stamping of the gearbox housing plate.
