[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1:

[0022] As Figure 1 and Figure 2As shown in the figure, a punching device for the positioning hole of a car door lock includes a base 1, and support legs 9 are fixedly installed around the lower surface of the base 1. On one side of the upper surface of the base 1, an L-shaped plate 2 is fixedly connected. A rotary punch mechanism 3 is rotatably connected through the top of the L-shaped plate 2. The rotary punch mechanism 3 includes a first rotating shaft 31 rotatably connected through the top of the L-shaped plate 2. The bottom end of the first rotating shaft 31 is fixedly connected with a first motor 32. The bottom end of the output shaft of the first motor 32 is fixedly connected with a turntable 33. A plurality of mounting columns 34 are slidably connected through the upper surface of the turntable 33 in a circular array. The bottom end of the mounting column 34 is detachably and fixedly connected with a punch body 35. The top end of the mounting column 34 is fixedly connected with a pressing plate 36. A spring 37 is fixedly connected between the pressing plate 36 and the upper surface of the turntable 33.

[0023] The rotation of the first rotating shaft 31 can drive the entire rotary punch mechanism 3 to rotate, so that different punch bodies 35 can be replaced according to the positioning holes of car door locks of different sizes, thus solving the problem that only the punch needs to be replaced when punching holes of different sizes in the existing device. When in use, a plurality of punch bodies 35 of the same size can be installed. When the punch body 35 is damaged, the first motor 32 can be started to drive the turntable 33 to rotate, and other punch bodies 35 can be directly used for punching operations without stopping for replacement, thereby improving work efficiency and solving the problem that the work efficiency is reduced when the punch of the existing device is damaged and can only be replaced by stopping the machine.

[0024] Embodiment 2:

[0025] As Figure 1 and Figure 3 shown in the figure, on one side of the top of the L-shaped plate 2, a punching mechanism 4 is fixedly installed through and is matched with the rotary punch mechanism 3. The punching mechanism 4 includes a cylinder 41 fixedly installed through the top of the L-shaped plate 2. The bottom end of the movable end of the cylinder 41 is fixedly connected with a push block 42 matched with the pressing plate 36.

[0026] When the cylinder 41 operates to drive the push block 42 to move downward, the pressing plate 36 can be pushed, thereby driving the mounting column 34 and the punch body 35 to move downward, and then the positioning hole of the car door lock can be punched.

[0027] Embodiment 3:

[0028] As Figure 1 and Figure 3As shown, a workbench 5 is fixedly installed on the upper surface of the base 1. A rotary lower die mechanism 6 for placing car door accessories is rotatably connected inside the workbench 5. The rotary lower die mechanism 6 includes a central hole opened on the upper surface of the workbench 5. A lower die disc 61 is rotatably connected inside the central hole. A plurality of punching holes 62 matching with the punch body 35 are annularly and arrayedly penetrated through the upper surface of the lower die disc 61. A second rotating shaft 63 is rotatably penetrated through the upper surface of the base 1. The top end of the second rotating shaft 63 is fixedly connected to the central position of the lower surface of the lower die disc 61.

[0029] The rotation of the second rotating shaft 63 can drive the rotation of the lower die disc 61, so that different punching holes 62 can be replaced according to different sizes of the punch body 35, which is convenient for cooperative punching.

[0030] Embodiment 4:

[0031] As Figure 1 and Figure 3 shown, a driving mechanism 7 matching with the rotary punch mechanism 3 and the rotary lower die mechanism 6 is installed between the base 1 and the L-shaped plate 2. The driving mechanism 7 includes a second motor 71 fixedly installed on the top of the L-shaped plate 2. The output shaft of the second motor 71 is fixedly connected to a third rotating shaft 72 rotatably connected to the base 1 and the L-shaped plate 2. First belt pulleys 73 are fixedly sleeved on the outer surfaces of the third rotating shaft 72 and the first rotating shaft 31. A first synchronous belt 74 is meshed and connected between the two first belt pulleys 73. Second belt pulleys 75 are fixedly sleeved on the outer surfaces of the third rotating shaft 72 and the second rotating shaft 63. A second synchronous belt 76 is meshed between the two second belt pulleys 75.

[0032] The rotation of the second motor 71 drives the rotation of the third rotating shaft 72, and the turntable 33 and the lower die disc 61 can be driven to rotate simultaneously through the first belt pulley 73, the first synchronous belt 74, the second belt pulley 75 and the second synchronous belt 76.

[0033] Embodiment 5:

[0034] As Figure 1 and Figure 3 shown, a waste material collection mechanism 8 matching with the rotary lower die mechanism 6 is arranged below the base 1. The waste material collection mechanism 8 includes a blanking hole 81 opened on the upper surface of the base 1. The blanking hole 81 is matched with the punching hole 62. A collection box 82 matched with the blanking hole 81 is arranged below the base 1.

[0035] The waste material punched by punching enters the collection box 82 through the blanking hole 81, which is convenient for collecting the waste material.

[0036] Working principle: During use, place the door accessory to be punched on the lower die plate 61 and fix it with an external fixture. Then, start the cylinder 41. The operation of the cylinder 41 drives the push block 42 to move downward, which can push the pressure plate 36, thereby driving the mounting post 34 and the punch body 35 to move downward. Thus, the punching of the positioning hole of the door lock can be carried out. After punching, the spring 37 will drive the punch body 35 to automatically reset, facilitating the next punching operation.

[0037] When punching positioning holes of different sizes is required, only need to start the second motor 71 at this time. The rotation of the second motor 71 drives the third rotating shaft 72 to rotate. Through the first belt pulley 73, the first synchronous belt 74, the second belt pulley 75 and the second synchronous belt 76, the turntable 33 and the lower die plate 61 can be driven to rotate simultaneously. Thus, the entire rotary punch mechanism 3 can be driven to rotate, and different punch bodies 35 and punching holes 62 can be replaced according to the positioning holes of door locks of different sizes, thereby solving the problem that only the punch needs to be replaced when punching holes of different sizes in the existing device.

[0038] During use, multiple punch bodies 35 of the same size can be installed. When the punch body 35 is damaged, start the first motor 32 to drive the turntable 33 to rotate, and other punch bodies 35 can be directly used for punching operations without stopping the machine for replacement, thereby improving work efficiency and solving the problem that the work efficiency is reduced because the punch can only be replaced by stopping the machine when it is damaged in the existing device.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.

[0040] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
