TECHNICAL FIELD

[0001] The utility model relates to the field of punching, in particular to a punch device for automobile parts for automobile processing. BACKGROUND

[0002] In the automobile manufacturing industry, due to the variety of parts, the size and specification of the required punching are also relatively large and diverse. Therefore, it is often necessary to use a punch device that can flexibly replace the tool bit, or to equip advanced punch equipment that can automatically switch the tool bit to meet production needs. However, the traditional tool bit replacement operation is often complex, not only time-consuming and labor-intensive, but also may affect production efficiency. At the same time, the existing automatic switching tool holder design also has certain safety hazards, and the tool bit is usually circularly distributed and exposed outward, which makes it easy for workers to be cut by sharp tool bits during operation, thereby increasing the risk of work accidents.

DETAILED DESCRIPTION

[0019] The utility model will be further described below in combination with the drawings and embodiments.

[0020] Please refer to Figs. 1 to 3 A punching device for automobile parts in automobile processing mainly comprises a stable rack 1 as a whole support. The rack 1 is composed of a bottom plate 19, a vertical plate 20 fixed on the bottom plate 19, and a top plate 21 fixed on the top of the vertical plate 20, forming a stable and vertical structure system, wherein the top plate 21 and the bottom plate 19 are located on the same side of the vertical plate 20, facilitating operation and observation.

[0021] On the top of the frame 1, i. e. the top plate 21, a hydraulic cylinder 2 is fixedly installed to provide a powerful power source for the punching operation. The output end of the hydraulic cylinder 2 is connected to a switching disc 3 through a flexible rotary connection. The switching disc 3 is particularly designed with a plurality of sliding grooves 4 arranged at equal angles, which are used to accommodate and guide the sliding of punching tools 5.

[0022] Each sliding groove 4 is slidably connected to a sharp punching tool 5, which is used for precise punching operation on automobile parts. One end of the punching tool 5 is provided with a punching part 12 for actual cutting of materials, and the part connected to the punching part 12 is designed with a square sliding part 13 to ensure stable and smooth sliding of the tool in the sliding groove.

[0023] A recess 6 communicating with the sliding grooves 4 is particularly provided at the center of the switching disc 3. In the recess 6, a cam 7 is rotatably connected, and the cam 7 is fixedly connected to the output end of the hydraulic cylinder 2. The side wall of the cam 7 is carefully engraved with a driving surface 8 matched with the end of the punching tool 5. In the sliding groove 4, a baffle 9 is also cleverly arranged to form an installation space for a spring 11 together with an annular plate 10 fixed on the side wall of the punching tool 5. The presence of the spring 11 provides a continuous thrust to the punching tool 5, ensuring that the roller 14 is always closely attached to the driving surface 8 of the cam 7.

[0024] Due to the unique design of the driving surface 8 of the cam 7 and the thrust of the spring 11, only the punching tool 5 directly below can be pushed out of the sliding groove 4 of the switching disc 3 by the cam 7 to perform the punching operation among the plurality of punching tools 5. The remaining punching tools 5 are safely hidden in the sliding grooves 4, effectively avoiding the risk of accidental injury.

[0025] In order to realize accurate control of the switching disc 3, a set of driving devices is also installed on the output end of the hydraulic cylinder 2. The set of devices includes a connecting plate 15 fixed on the output end of the hydraulic cylinder, and one end of the connecting plate 15 is fixedly installed with a servo motor 16. The output end of the servo motor 16 is engaged with a driven gear 18 on the back of the switching disc 3 through a driving gear 17, thereby realizing precise rotary control of the switching disc 3.

[0026] It is worth mentioning that the switching disc 3 is parallel to the vertical plate 20, which not only makes the operation space of the workers more spacious, but also greatly improves the visual conditions, making the whole punching process more intuitive, efficient and safe.

[0027] It should be emphasized that one of the sliding grooves 4 can also be installed with a punching tool 5, and all the punching tools 5 can be stored in the sliding grooves 4 when not in use, which is safer.

[0028] The working principle is as follows:

[0029] Initial state and preparation:

[0030] The device is in standby state, hydraulic cylinder 2 is not started, all punching tools 5 are limited in the initial position of each sliding slot 4 by the baffle 9 and the ring plate 10 under the action of the spring 11. The cam 7 is located in the groove 6 in the center of the switching disc 3, and the driving surface 8 thereof is in contact with the roller 14 at the end of each punching tool 5.

[0031] The servo motor 16 is not started, and the switching disc 3 remains stationary.

[0032] Select the punching tool 5:

[0033] According to the size of the hole of the automobile part, select the punching tool 5 of corresponding size, and start the servo motor 16 through the control system. The servo motor 16 drives the switching disc 3 to rotate a certain angle below the top plate 21 of the rack 1 through the meshing of the driving gear 17 and the driven gear 18, so that the corresponding punching tool 5 is directly below.

[0034] The rotation of the switching disc 3 drives the sliding slot 4 and the punching tool 5 thereon to rotate. Because of the design of the driving surface 8 of the cam 7, only the punching tool 5 directly below (i.e. the tool corresponding to the highest point of the driving surface 8 of the cam 7) will slide downward in the sliding slot 4 through the square sliding part 13 under the push of the spring 11, so that the punching part 12 thereof extends out of the switching disc 3, ready for punching operation.

[0035] The remaining punching tools 5 are kept in the sliding slot 4 due to the shape of the driving surface 8 of the cam 7 and the force of the spring 11, and will not extend out of the switching disc 3, thereby avoiding injury or interference.

[0036] Punching operation:

[0037] When the punching tool 5 at the required punching position is aligned with the automobile part, the hydraulic cylinder 2 is started, and the output end thereof moves downward, driving the switching disc 3 and the selected punching tool 5 to move downward together.

[0038] With the downward movement of the punching tool 5, the punching part 12 thereof penetrates the automobile part, completing the punching operation.

[0039] Reset:

[0040] After the punching is completed, the output end of the hydraulic cylinder 2 moves upward, driving the switching disc 3 and the punching tool 5 to move upward together, returning to the initial position.

[0041] The above merely illustrates the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which are made by using the content of the present application specification and drawings, are also included in the patent protection scope of the present application.
