[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-5 As shown, a positioning and drilling device for automobile fork shaft production comprises a punching device body 1; a positioning plate 11 is installed at the bottom inner side of the punching device body 1; a screw fixing sleeve 12 is installed on the top of the positioning plate 11; a fixing column 13 is fixedly connected to one end of the positioning plate 11; a rotating cylinder 14 is slidably connected to the outside of the fixing column 13; a limiting plate 15 is fixedly connected to the outside of the rotating cylinder 14; a telescopic rod 16 is fixedly connected to the top of the end of the limiting plate 15 away from the rotating cylinder 14; an extrusion block 17 is fixedly connected to the telescopic end of the telescopic rod 16; a first slide groove 18 is opened at one end of the limiting plate 15; an extrusion block 17 is slidably connected inside the first slide groove 18; when working, the fork shaft is first placed above the positioning plate 11, and then the screw fixing sleeve 12 is used to align the fork shaft circle The cylindrical part is fixed and clamped, and then the rotating drum 14 outside the fixed column 13 is rotated to drive the limit plate 15 to enter one end of the fork shaft, and then the limit plate 15 is driven to extend and retract to make the extrusion block 17 rise, and the first slide groove 18 limits the extrusion block 17. At this time, the punching device body 1 is driven to punch holes in the fork shaft. In this step, when punching the fork shaft, because a part of the fork shaft is cylindrical, when fixing the fork shaft, a large force may damage the surface of the fork shaft, and a small force may not be fixed firmly enough. Therefore, when clamping the cylindrical area of the fork shaft, one end of the fork shaft is squeezed and limited by the extension and retraction of the telescopic rod 16 and the extrusion block 17. Since the fixed column 13 is fixed, one end of the fork shaft can be kept stable, which increases the stability of the fork shaft when being punched.

[0025] like Figure 1-2 、 Figure 4 As shown, a second slide groove 2 is provided at the bottom inner side of the punching device body 1; a first slider 21 is fixedly connected to the bottom of the positioning plate 11; the first slider 21 is slidably connected inside the second slide groove 2; a groove 22 is provided inside the second slide groove 2; a spring 23 is fixedly connected inside the groove 22; a rotating cylinder 14 is fixedly connected to the top end of the spring 23; a second slider 24 is slidably connected inside the groove 22; when working, the positioning plate 11 is slid into the inside of the punching device body 1 through the first slider 21 for fixing, and a first slider 21 is also provided on the side of the positioning plate 11, which can realize the flipping of the positioning plate 11, so that the direction in which holes can be punched is increased. Then, when the first slider 21 is slid into the second slide groove 2, the second slider 24 will be squeezed, causing the second slider 24 to drop into the groove 22 and squeeze the spring 23 at the same time. When not squeezed, the second slider 24 pops out to limit the first slider 21. When it needs to be taken out, press the second slider 24 to take it out. This step may have some special requirements when punching holes in the fork shaft, and it is necessary to punch holes in different positions. The direction in which the positioning plate 11 is fixed above the punching device body 1 can be adjusted to increase the operability of the punching. At the same time, the first slider 21 is fixed by the second slider 24 to improve the stability during punching.

[0026] like Figure 1 、 Figure 3 As shown, a blowing device 3 is fixedly connected to one end of the top of the punching device body 1; an adjustable pipe 31 is fixedly connected to the end of the blowing device 3 away from the punching device body 1; a nozzle 32 is fixedly connected to the end of the adjustable pipe 31 away from the blowing device 3; when the fork shaft is being punched during operation, the blowing device 3 moves along with the drill bit. When drilling, the position of the nozzle 32 is first adjusted through the adjustable pipe 31 so that it is facing the drill hole, and then the blowing device 3 is driven to blow air into the drill hole. This step will generate a large amount of debris and heat during the drilling process. These debris may cause the drill bit to deviate, and the heat will accelerate the wear of the drill bit, so the nozzle 32 is used to blow air to it to remove the generated debris and heat, thereby reducing the wear of the drill bit.

[0027] like Figure 1 、 Figure 4-5 As shown, a limiting groove 4 is provided on the outside of the fixed column 13; a fixing block 41 is fixedly connected to the top of the rotating drum 14; a limiting latch 42 is slidably connected inside the fixed block 41; and a limiting latch 42 is slidably connected inside the limiting groove 4; when the rotating drum 14 is adjusted to a suitable height outside the fixed column 13 during operation, the limiting latch 42 is pressed to pass through the fixed block 41 and reach the inside of the limiting groove 4. In this step, when fixing the end of the fork shaft, a limiting device is added to the fixed column 13 and the rotating drum 14 bracket, which can make it more stable when punching.

[0028] like Figure 1 、 Figure 4 As shown, a detachable block 5 is slidably connected to the bottom inner side of the punching device body 1 near the second slide groove 2; a threaded column 51 is threadedly connected to the internal thread of the detachable block 5; when working, when the first slider 21 is installed in the second slide groove 2, the detachable block 5 is installed in the punching device body 1, and then the threaded column 51 is rotated to squeeze the first slider 21. When the first slider 21 needs to be removed, the detachable block 5 is removed. In this step, when the first slider 21 is fixed by the second slider 24, instability may still occur. Therefore, the first slider 21 is limited again by the threaded column 51, thereby increasing the stability of the first slider 21.

[0029] like Figure 1 、 Figure 3 As shown, a rubber pad 6 is fixed to the inner side of the screw fixing sleeve 12; when the screw fixing sleeve 12 fixes the fork shaft during operation, the rubber pad 6 acts as a buffer. This step not only increases the friction between the fork shaft and the screw fixing sleeve 12, but also reduces the damage that the screw fixing sleeve 12 may cause to the fork shaft.

[0030] like Figure 1 、 Figure 4 As shown, a margin hole 7 is provided on the top of the extrusion block 17; when working, the margin hole 7 is located at the top of the extrusion block 17. In this step, when it is necessary to mechanically drill a hole at the end of the fork shaft, the margin hole 7 will leave a certain buffer space for the drill bit, thereby reducing the damage of the drill bit to the extrusion block 17.

[0031] The working principle is as follows: first, the fork shaft is placed above the positioning plate 11, and then the cylindrical part of the fork shaft is fixedly clamped with the screw fixing sleeve 12, and then the rotating cylinder 14 outside the fixing column 13 is rotated to drive the limiting plate 15 to enter one end of the fork shaft, and then the limiting plate 15 is driven to extend and retract to make the extrusion block 17 rise, and the first slide groove 18 limits the extrusion block 17. At this time, the punching device body 1 is driven to punch holes in the fork shaft. In this step, when punching holes in the fork shaft, because a part of the fork shaft is cylindrical, when fixing the fork shaft, a large force may damage the surface of the fork shaft, and a small force may not be fixed firmly enough. Therefore, when clamping the cylindrical area of the fork shaft, one end of the fork shaft is squeezed and limited by the extension of the telescopic rod 16 and the extrusion block 17. Since the fixing column 13 is fixed, The first slider 21 is fixed, so one end of the fork shaft can be kept stable, which increases the stability of the fork shaft when being punched. The positioning plate 11 is slid into the punching device body 1 through the first slider 21 for fixation. A first slider 21 is also provided on the side of the positioning plate 11, which can realize the flipping of the positioning plate 11, so that the direction of punching can be increased. Then, when the first slider 21 is slid into the second slide groove 2, the second slider 24 will be squeezed, so that the second slider 24 will drop into the groove 22 and the spring 23 will be squeezed at the same time. When it is not squeezed, the second slider 24 pops out to limit the first slider 21. When it needs to be taken out, press the second slider 24 to take it out. This step may have some special requirements when punching holes in the fork shaft, and holes need to be punched in different positions. The entire positioning plate 11 is fixed in the direction above the punching device body 1 to increase the operability of punching. At the same time, the first slider 21 is fixed by the second slider 24 to improve the stability during punching. When punching the fork shaft, the air blowing device 3 moves with the drill bit. When punching, first adjust the position of the nozzle 32 through the adjustable pipe 31 so that it is directly opposite to the drill hole, and then drive the air blowing device 3 to blow air into the drill hole. This step will generate a lot of debris and heat during the drilling process. These debris may cause the drill bit to deviate, and the heat will accelerate the wear of the drill bit. Therefore, it is blown by the nozzle 32 to remove the generated debris and heat, thereby reducing the wear of the drill bit. When the rotating drum 14 is adjusted to a suitable height outside the fixed column 13, the limit pressure is pressed. The first slider 21 is fixed to the second slide groove 2 by the screw threaded rod 51, and the first slider 21 is fixed to the second slide groove 2 by the screw threaded rod 51, and the first slider 21 is fixed to the second slide groove 2 by the screw threaded rod 51. When the first slider 21 needs to be removed, the detachable block 5 is removed. In this step, when the second slider 24 is used to fix the first slider 21, instability may still occur. Therefore, the first slider 21 is limited again by the screw threaded rod 51, which increases the stability of the first slider 21. When the fork shaft is fixed by the screw fixing sleeve 12,The rubber pad 6 acts as a buffer. This step not only increases the friction between the fork shaft and the screw fixing sleeve 12, but also reduces the damage that the screw fixing sleeve 12 may cause to the fork shaft. The allowance hole 7 is located at the top of the extrusion block 17. In this step, when it is necessary to drill a hole at the end of the fork shaft, the allowance hole 7 will leave a certain buffer space for the drill bit, reducing the damage to the extrusion block 17 caused by the drill bit.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
