[0001] The utility model relates to metal sheet processing technical field, specifically point to a kind of adsorption fixed thin metal sheet punching device. BACKGROUND

[0002] The punching device is a kind of equipment for punching on various materials. From the structure, it usually contains power part, transmission part and punching working part. The power part provides the energy required for punching, such as motor. The transmission part can effectively transmit and convert power, so that the punching working part can operate accurately. The working part is the component that directly contacts with the material for punching, and there are various forms according to different punching materials and size requirements.

[0003] At present, when performing punching operation on thin metal sheet, the conventional way has many drawbacks. In most cases, the thin metal sheet is fixed by hydraulic mechanism or electric mechanism to ensure the stability of the material during punching. However, this kind of clamping method is often difficult to control the force, and it is easy to cause deformation such as indentation and bending of the edge of the thin metal sheet due to excessive force, which damages the original flatness and integrity of the material. At the same time, in the operation process of hand-held drilling machine, it is greatly affected by human factors, and it is difficult to maintain absolute stability with hands, so the position and perpendicularity of punching are easy to deviate, which greatly reduces the punching precision and is difficult to meet the high-precision processing requirements. UTILITY MODEL CONTENT

[0005] To solve the above technical problems, the utility model provides a technical scheme: an adsorption fixed thin metal sheet punching device, comprising a punching seat, a fixing seat is fixed on the upper side of the punching seat through a plurality of supporting rods, a vacuum adsorption disc is fixed at the lower end of the fixing seat, the vacuum adsorption disc is controlled by a negative pressure pump fixed on the punching seat, an adsorption hole matched with the vacuum adsorption disc is arranged at the upper side of the fixing seat, a punching plate is arranged on the upper side of the fixing seat, the punching plate is driven to rise and fall by a lead screw drive fixed on the punching seat, a drilling machine is arranged below the punching plate, the drilling machine is driven by a double-shaft sliding table fixed below the punching plate, a positioning sensor is arranged on the side of the drilling machine and the punching seat, and a control panel is arranged on the punching seat.

[0006] Further, a plurality of pads are fixed at the four corners below the punching seat, and a plurality of anti-skid rubber strips are arranged below the pads.

[0007] Further, the supporting rods are fixed at the four corners below the fixing seat.

[0008] Furthermore, a lifting block is integrally formed at the four corners above the fixing base, and the adsorption hole is located on the lifting block.

[0009] Furthermore, the dual-axis slide includes an X-axis guide rail and a Y-axis guide rail that respectively control the horizontal and vertical movement of the punching machine along the fixed base.

[0010] Furthermore, the punching machine is fixedly mounted on a moving plate driven by a dual-axis slide table, and the positioning sensor is located on one side of the punching machine on the moving plate. The punching base has four positioning sensors, which are respectively located on each lifting block.

[0011] Compared with existing technologies, the advantages of this invention are as follows: The device uses a vacuum adsorption plate controlled by a negative pressure pump to adsorb and fix the thin metal sheet from below, which can effectively avoid damage caused by excessive pressure on the edge of the thin metal sheet. Furthermore, the multiple adsorption holes ensure stable fixation of the thin metal sheet, providing a stable foundation for precise drilling. The drilling machine can stably rise and fall with the drilling plate under the drive of a lead screw driver, ensuring good drilling verticality. The drilling machine is driven by a dual-axis slide table, and under the action of a positioning sensor, it can accurately move to the drilling position, thereby reducing drilling errors and improving drilling accuracy.
