[0018] The present invention will be further explained below with reference to specific embodiments.

[0019] like Figure 1 As shown, this embodiment provides a punching device for axle housing body of an automobile drive axle, and the punching device for axle housing body of an automobile drive axle comprises: The base 1 and the side plate 2, the side plate 2 is fixedly mounted on the base 1, and the end of the side plate 2 away from the base 1 is fixedly connected to the top plate 3; the supporting mechanism 4 is mounted on the two side plates 2 for fixing the bridge housing body, the supporting mechanism 4 can be flipped to pour out the punching waste of the bridge housing body, and a collection box 5 for collecting the poured-out punching waste is placed on the base 1; the hydraulic telescopic rod 6 is fixedly mounted on the top plate 3, the power output end of the hydraulic telescopic rod 6 is fixedly connected to the trough body 7, the hydraulic telescopic rod 6 is used to drive the trough body 7 to rise or fall, the power input end of the supporting mechanism 4 is connected to the trough body 7, and the rise and fall of the trough body 7 can drive the supporting mechanism 4 to flip; the punching mechanism 8 is mounted on the trough body 7, and the power output end of the punching mechanism 8 can adjust the position to punch different positions of the bridge housing body; the cooling mechanism 9 is mounted on the top plate 3 and the trough body 7, and the water outlet end of the cooling mechanism 9 is connected to the punching mechanism 8, for cooling the bridge housing body when punching holes in the bridge housing body.

[0020] When using the automobile drive axle bridge housing body punching device, first put the bridge housing body that needs to be punched on the supporting mechanism 4 and insert the right end of the bridge housing body into the right side of the supporting mechanism 4, pull the control end of the supporting mechanism 4, so that the left side of the supporting mechanism 4 is clamped into the left end of the bridge housing body. After the bridge housing body is fixed, open the punching mechanism 8, adjust the lower end of the punching mechanism 8 to the position where the bridge housing body needs to be punched, and then open the hydraulic telescopic rod 6. The hydraulic telescopic rod 6 can drive the trough body 7 to move downward, thereby driving the punching mechanism 8 to move downward and punch the bridge housing body. The punching mechanism During the downward movement of 8, the cooling mechanism 9 opens and provides cooling water to the punched position, so that the bridge shell body can be cooled during the punching process to avoid the temperature of the punching position of the bridge shell body being too high. During the punching process, the supporting mechanism 4 can flip over and collect the punching waste. After punching, the hydraulic telescopic rod 6 drives the trough body 7 to move upward and reset. At the same time, the cooling mechanism 9 is closed, and the trough body 7 drives the supporting mechanism 4 to flip over in the opposite direction. The supporting mechanism 4 can support the bridge shell body again, and the punching waste temporarily collected by the supporting mechanism 4 can be poured into the collection box 5 for collection.

[0021] like Figure 1 As shown, as a preferred embodiment of the present invention, the supporting mechanism 4 includes: a rotating rod 41, whose two ends are rotatably connected to the two side plates 2, and the rotating rod 41 is fixed with a storage box 42 for temporarily storing punching waste; a buffer component 43, which is fixedly installed on the rotating rod 41, and the buffer component 43 is fixed with a bearing plate 44 for supporting the bridge housing body; a fixed sleeve 45, which is fixed on one of the side plates 2, and the right end of the bridge housing body can be inserted into the fixed sleeve 45; a tightening component 46, which is installed on the other side plate 2, and is used to be fitted onto the left end of the bridge housing body to fix the bridge housing body; a flip rack 47, which is fixed on the slot body 7, and the flip rack 47 is engaged with a flip gear 48 fixed on the rotating rod 41.

[0022] Before punching the bridge housing body, it is necessary to place the bridge housing body stably. Specifically, put the bridge housing body on the bearing plate 44 and insert the right end into the fixing sleeve 45. Then pull the control end of the tightening component 46. The tightening component 46 can be clamped to the left end of the bridge housing body under the action of elastic force, thereby fixing the bridge housing body. When punching, the groove body 7 moves downward to drive the flip rack 47 to move downward, thereby driving the flip gear 48 and the rotating rod 41 to rotate on the side plate 2. The rotation of the rotating rod 41 can gradually rotate the buffer component 43 and the bearing plate 44 To the bottom, the buffer assembly 43 can provide buffering during the rotation process to avoid interference between the supporting plate 44 and the bridge housing body, and the storage box 42 can be rotated upward by the casting, and the waste generated when the bridge housing body is punched can fall into the storage box 42 for temporary storage. After the punching is completed, the trough body 7 drives the flip rack 47 to move upward, thereby driving the flip gear 48 and the rotating rod 41 to rotate in the opposite direction, and the supporting plate 44 can be rotated downward and re-lift the bridge housing body, while the storage box 42 rotates downward and pours the punching waste inside into the collection box 5 for unified collection.

[0023] like Figure 2 As shown, as a preferred embodiment of the present invention, the buffer assembly 43 includes: a sliding column 431, which is fixed on the rotating rod 41, and the end of the sliding column 431 away from the rotating rod 41 is fixedly connected to the limiting plate 432; a sliding sleeve 433, which is sleeved on the sliding column 431, and a limiting column 434 is fixedly arranged in the sliding sleeve 433, and a buffer spring 435 sleeved on the limiting column 434 is fixed between the limiting plate 432 and the inner wall of the sliding sleeve 433.

[0024] When the supporting plate 44 rotates downward, since the rotation of the supporting plate 44 is an arc, under the obstruction of the bridge housing body, the supporting plate 44 can push the sliding sleeve 433 and the limiting column 434 to move downward along the sliding column 431 and the limiting plate 432 and compress the buffer spring 435, thereby achieving buffering of the supporting plate 44. At the same time, the design of the buffer spring 435 can also provide buffering when the bridge housing body is placed on the supporting plate 44, preventing the supporting plate 44 from being subjected to excessive impact force.

[0025] like Figure 3As shown in FIG. 1 , as a preferred embodiment of the present invention, the tightening assembly 46 includes: a guide rod 461, which is fixedly mounted on the side plate 2; a guide sleeve 462 is sleeved on the guide rod 461; a movable sleeve 463 is fixedly mounted on the guide sleeve 462; a push spring 464 is fixed between the guide sleeve 462 and the side plate 2 for pushing the movable sleeve 463 to fit the left end of the axle housing body; an L-shaped rod 465, which is fixed on the guide sleeve 462 and passes through the side plate 2; and the L-shaped rod 46 5 is fixed with a card plate 466, which is fixedly connected to a handle 467 and has a bayonet slot; a fixed plate 468 is fixedly installed on the side plate 2, and a pull rod 469 is slidably provided on the fixed plate 468, one end of the pull rod 469 is fixedly connected to a pull handle 4610, and the other end is fixedly connected to a card block 4611, and a compression spring 4612 is fixed between the card block 4611 and the fixed plate 468 for pushing the card block 4611 into the bayonet slot provided on the card plate 466.

[0026] When the movable sleeve 463 is inserted into the left end of the bridge housing body, the pull handle 4610 is pulled, and the pull handle 4610 drives the pull rod 469 and the clamping block 4611 to move downward along the fixed plate 468 and compress the compression spring 4612, and the clamping block 4611 can be separated from the bayonet opening opened by the clamping plate 466. At this time, the push spring 464 can push the guide sleeve 462 and the movable sleeve block 463 to move to the right along the guide rod 461, and the movable sleeve block 463 can be inserted into the left end of the bridge housing body to ensure that the bridge The shell body is stable during punching. After the punching is completed, pull the handle 467, and the handle 467 can drive the clamping plate 466, the L-shaped rod 465, the guide sleeve 462 and the movable sleeve block 463 to move to the left along the guide rod 461 and compress the push spring 464. When the bayonet opening opened by the clamping plate 466 is flush with the clamping block 4611, the compression spring 4612 can push the clamping block 4611 into the bayonet opening, so that the clamping plate 466 can be locked, making it convenient to remove the bridge shell body after punching.

[0027] like Figure 1 and Figure 4 As shown, as a preferred embodiment of the present invention, the punching mechanism 8 includes: a moving component 81, which is installed on the trough body 7, and the power output end of the moving component 81 is fixedly connected to the heat sink 82, and the moving component 81 is used to drive the heat sink 82 to move, and a first power member 83 is fixedly installed in the heat sink 82, and the output shaft of the first power member 83 is fixedly connected to the first gear 84; a rotating column 85, which is rotatably installed in the heat sink 82, and a second gear 86 that meshes with the first gear 84 is fixed on the rotating column 85; a punch 87, which is fixedly connected to the rotating column 85 and is used to punch the bridge housing body.

[0028] When punching the bridge housing body, the moving component 81 is turned on, and the moving component 81 drives the heat sink 82 to move, so that the punch 87 can be moved to the position directly above the required punching position of the bridge housing body, and then the first power component 83 is turned on. The first power component 83 is specifically a motor. The output shaft of the first power component 83 drives the first gear 84 to rotate, and the first gear 84 drives the second gear 86 and the rotating column 85 to rotate, thereby driving the punch 87 to rotate. At this time, turning on the hydraulic telescopic rod 6 can push the punch 87 to move downward and punch the bridge housing body.

[0029] like Figure 5 As shown, as a preferred embodiment of the present invention, the moving assembly 81 includes: a second power member 811, which is installed on the groove body 7, and the output shaft of the second power member 811 is fixedly connected to the active bevel gear 812; a threaded rod 813, both ends of which are rotatably connected to the inner wall of the groove body 7, and one side of the threaded rod 813 is fixed with a driven bevel gear 814 that meshes with the active bevel gear 812; a cross bar 815, both ends of which are fixedly connected to the inner wall of the groove body 7, and the cross bar 815 is provided with a threaded connection with the threaded rod 813.

[0030] When adjusting the position of the punch 87, turn on the second power member 811, which is specifically a motor. The output shaft of the second power member 811 drives the active bevel gear 812 to rotate, and the active bevel gear 812 drives the driven bevel gear 814 and the threaded rod 813 to rotate. The rotation of the threaded rod 813 can make the movable groove 816 move along the cross bar 815, thereby driving the punch 87 to move left and right. If the punch 87 is to be moved forward and backward, turn on the third power member 819, which is specifically a motor. The output shaft of the third power member 819 drives the threaded column 818 to rotate. The rotation of the threaded column 818 can make the guide wheel 8111 on the movable block 8110 move along the wheel groove, thereby driving the punch 87 to move forward and backward until the punch 87 is moved to the top of the punching position required for the bridge housing body.

[0031] like Figure 1 、 Figure 6 、 Figure 7 as well as Figure 8As shown, as a preferred embodiment of the present invention, the cooling mechanism 9 includes: a water tank 91, which is fixedly mounted on the top plate 3, an air inlet is provided at the top of the water tank 91, a water adding bucket 92 for adding water into the water tank 91 is installed on the water tank 91, the water adding bucket 92 can be closed, a water outlet pipe 93 is connected to the lower end of the water tank 91, the water outlet pipe 93 is connected to a hose 94, and a nozzle 95 fixedly connected to the heat dissipation box 82 is connected to the hose 94; a triangular block 96 is fixed on the trough body 7, a bending rod 97 passing through the top plate 3 is fixedly connected to the top of the triangular block 96, the bending rod 97 extends into the water tank 91 and is fixedly connected to a pressure plate 98, and the pressure plate 98 is provided with an air guide hole; a protective box 99 is provided with two and is respectively fixed on the inner wall of the top of the water tank 91 and the pressure plate 98, a shaft 910 is rotatably provided on the protective box 99, and a shaft 910 is fixed on the shaft 910 A turntable 911 is provided, on which a torsion spring 912 connected to the inner wall of the protective box 99 is fixed, a swing frame 913 is fixed on the shaft 910, and a sealing plate 914 is fixed on the swing frame 913, and the two sealing plates 914 are respectively used to control the opening and closing of the air inlet and the air guide hole; a support sleeve 915 is fixed at the lower end of the water tank 91, and a wheel rod 916 is slidably provided in the support sleeve 915, and a pulley 917 that is in sliding contact with the triangular block 96 is installed at one end of the wheel rod 916, and a return spring 918 is fixedly connected between the pulley 917 and the support sleeve 915, and the other end of the wheel rod 916 extends into the water outlet pipe 93; a spoiler 919 is fixed in the water outlet pipe 93 and is provided with a water outlet, and a sealing plate 920 for controlling the opening and closing of the water outlet is slidably provided on the lower side of the spoiler 919, and the other end of the wheel rod 916 is fixedly connected to the sealing plate 920.

[0032] In this embodiment, the hose 94 has a sufficient length to ensure that the moving assembly 81 can drive the punch 87 to move smoothly left and right and the trough body 7 can move smoothly up and down.

[0033] During the punching process of the bridge housing body, it is necessary to cool the bridge housing body and the punch 87. Specifically, cooling water is added from the water adding bucket 92 into the water tank 91 for storage. After adding, when punching, the hydraulic telescopic rod 6 drives the trough body 7 to move downward, and the downward movement of the trough body 7 drives the triangular block 96 to move downward. The downward movement of the triangular block 96 can make the pulley 917 push the wheel rod 916 to slide along the support sleeve 915 and compress the return spring 918. The wheel rod 916 can push the sealing plate 920 to slide along the spoiler 919, and the water outlet is When the triangular block 96 moves downward, it can drive the bending rod 97 and the pressure plate 98 to move downward. The sealing plate 914 on the lower side can quickly close the air guide hole under the pull of the torsion spring 912. Since the pressure plate 98 is in a negative pressure state, the external air can push the sealing plate 914 on the upper side to rotate downward and make the torsion spring 912 produce a restoring elastic force. The external air can enter the water tank 91 and be under the pressure plate 98. As the pressure plate 98 moves downward, the pressure plate 98 can pressurize the water in the water tank 91. Water can be sprayed out from the water tank 91 through the water outlet pipe 93, the hose 94 and the nozzle 95 at a certain pressure, and the cooling water can flow into the position where the bridge housing body needs to be punched, so as to cool the bridge housing body and the punch 87. After the punching is completed, the hydraulic telescopic rod 6 drives the groove body 7 to move upward, and the upward movement of the groove body 7 drives the triangular block 96 to move upward. After the triangular block 96 moves upward, the return spring 918 can push the pulley 917 and the wheel rod 916 to move to the right along the support sleeve 915, so that the sealing plate 920 can be pulled to block the The water outlet opened by the flow plate 919 is closed, and the triangular block 96 moves upward, which can drive the pressure plate 98 on the bending rod 97 to move upward. The pressure plate 98 moves upward, and the upper torsion spring 912 pulls the upper sealing plate 914 to move upward, so that the air inlet can be immediately closed. The lower sealing plate 914 can be rotated downward under the action of air pressure and the torsion spring 912 generates a restoring elastic force, and the air guide hole can be opened, and air can flow into the water tank 91 below the pressure plate 98, so that the water can be pressurized during the next punching.
