Description

Technical Field

[0001] This utility model relates to the field of punching equipment technology, and in particular to a punching equipment with rapid positioning function for the production of automotive parts. Background Technology

[0002] In the automotive parts manufacturing process, punching is one of the key processes, and its processing efficiency and precision directly affect the assembly quality and production cost of the entire vehicle. As the automotive industry develops towards multi-variety, small-batch, and customized production, the problems of high manual intervention, long mold change cycles, and low automation levels of traditional punching equipment are becoming increasingly prominent.

[0003] Traditional punching equipment generally adopts a manual feeding, positioning, and unloading mode, which has three major drawbacks: First, manual positioning relies on operating experience, and the hole position deviation rate can reach ±0.5mm, which is difficult to meet the high precision requirements of lightweight components for new energy vehicles; Second, the loading and unloading time for a single batch can be as long as 15-20 seconds, which, in a production line with an annual output of 100,000 pieces, results in a cumulative waste of more than 800 hours per year; Third, operators frequently come into contact with moving parts, posing safety hazards such as finger pinching injuries.

[0004] Regarding mold replacement, existing equipment mostly uses bolt fastening or pressure plate locking structures. When changing molds, tools are needed to remove 8-12 bolts, and a single mold change takes 15-20 minutes. Moreover, mold positioning relies on manual tool setting, resulting in a first-piece scrap rate as high as 5%-8%. For flexible production lines that need to frequently switch product models, the long downtime for mold change severely restricts production capacity.

[0005] Therefore, those skilled in the art have provided a punching device with rapid positioning function for the production of automotive parts to solve the problems mentioned in the background art. Utility Model Content

[0006] To address the issues of traditional punching equipment's inability to quickly change punching dies and its inability to automate loading and unloading, this invention provides a punching equipment for automotive parts production with rapid positioning capabilities.

[0007] This utility model provides a punching equipment with rapid positioning function for the production of automotive parts, and adopts the following technical solution:

[0008] A punching device for producing automotive parts with rapid positioning function includes a punching assembly. A fixing component is fixedly connected to the surface of the punching assembly, and automatic loading and unloading components are fixedly connected to both sides of the top of the punching assembly. The punching assembly includes a frame, and a hydraulic telescopic rod is fixedly connected to the top of the inner cavity of the frame. A punching die is movably connected to the bottom of the hydraulic telescopic rod through the fixing component. A moving groove is provided on both sides of the top of the punching die. The fixing component includes an extrusion block slidably connected to the inner cavity of the moving groove. A lead screw is fixedly connected to one side of the extrusion block through a bearing. The lead screw is threaded to the top of the punching die. A limiting sleeve is fitted on the surface of the punching die and on the top of the extrusion block. A pin is provided through the hydraulic telescopic rod and the inner cavity of the punching die. The automatic loading and unloading components include a vacuum machine fixedly connected to the top of the frame and loading and unloading robots fixedly connected to the rear ends of both sides of the top of the frame.

[0009] Optionally, the top of the frame is provided with a through hole for matching the punching die, and a waste receiving box is placed at the bottom of the frame, and a controller is fixedly connected to the back of the frame.

[0010] Optionally, the punching die includes a threaded connecting pipe, which is threadedly connected to the output end of the hydraulic telescopic rod. A connecting plate is fixedly connected to the bottom of the threaded connecting pipe. The connecting plate has a hexagonal design, and a punching die rod is fixedly connected to the bottom axis of the connecting plate.

[0011] Optionally, the movable groove is formed on both sides of the top of the connecting plate, and a support screw block for use with the lead screw is fixedly connected to the outside of the movable groove.

[0012] Optionally, the hydraulic telescopic rod has receiving grooves for use with the mating pin at one end of the inner cavity of the threaded connecting pipe and on both sides of the threaded connecting pipe, and a limiting ring of the blocking limiting sleeve is fixedly connected to the top of the surface of the threaded connecting pipe.

[0013] Optionally, a handwheel is fixedly connected to the end of the lead screw away from the extrusion block, and the surface of the handwheel is provided with anti-slip texture.

[0014] Optionally, both the loading robot and the unloading robot include servo motors. The output shaft of the servo motor is fixedly connected to a connecting seat. The other end of the connecting seat is fixedly connected to a hydraulic telescopic rod II. The bottom of the hydraulic telescopic rod II is fixedly connected to a vacuum adsorption plate. The top of the vacuum adsorption plate is connected to a valve.

[0015] Optionally, the top of the vacuum adsorption plate is connected to a pipe via a vacuum hose, and the other end of the pipe extends through to the top of the connector and is connected to a vacuum pump via a vacuum hose.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. This utility model integrates a loading robot, a unloading robot, and a vacuum adsorption system to achieve unmanned loading and unloading operations for automotive parts. The servo motor-driven robotic arm can quickly and accurately grasp and position the workpiece, greatly improving efficiency compared to traditional manual operation and completely eliminating the safety hazards of personnel contacting the equipment. The vacuum adsorption plate forms a stable negative pressure through a vacuum pump, which is suitable for parts made of various materials such as aluminum alloy and steel plate, avoiding hole position deviations caused by manual positioning and greatly improving punching accuracy. The automatic loading and unloading system is linked with the punching components, greatly reducing the idle time of the equipment and greatly improving the single-shift production capacity compared to traditional equipment. It is especially suitable for rapid switching in multi-variety, small-batch production scenarios.

[0018] 2. The fixing component of this utility model adopts a triple locking design of "lead screw-extrusion block-pin": rotating the handwheel drives the lead screw to rotate, causing the extrusion block to slide along the moving groove, thus completing the mechanical locking between the mold and the hydraulic telescopic rod; the pin passes through the receiving groove of the hydraulic telescopic rod and the threaded connecting pipe to form circumferential positioning and axial limiting, avoiding the tool setting error of traditional bolt connection. The matching structure of the hexagonal connecting plate and the limiting sleeve ensures automatic centering during mold installation, greatly reducing the total mold changing time and meeting the needs of frequent mold changing in flexible production lines. This design is also compatible with punching die rods of different specifications. By changing the connecting plate, it can adapt to different hole diameter processing, significantly enhancing the equipment's versatility. Attached Figure Description

The limiting sleeve 23 is set on the top of the extrusion block 21 and cooperates with the extrusion block 21 to seal and fix the pin 24. The loading robot 32 and the unloading robot 33 are symmetrically distributed at the top rear end of the frame 11 and are driven by a six-axis servo motor 331. The vacuum adsorption plate 334 is connected to the vacuum pump 31 through a vacuum hose and a pipe 335. The valve is used to release negative pressure and realize the unloading function.

[0030] Example 2:

[0031] Reference Figure 1-5The top of the frame 11 has a through hole 15 for the punching die 13, and a waste receiving box is placed at the bottom of the frame 11. A controller 4 is fixedly connected to the back of the frame 11. The punching die 13 includes a threaded connecting pipe, which is threadedly connected to the output end of the hydraulic telescopic rod 12. A connecting plate is fixedly connected to the bottom of the threaded connecting pipe. The connecting plate has a hexagonal design, and a punching die rod is fixedly connected to the bottom axis of the connecting plate. A moving groove 14 is opened on both sides of the top of the connecting plate, and a support screw block for the lead screw 22 is fixedly connected to the outside of the moving groove 14. The hydraulic telescopic rod 12 has receiving grooves 25 for the pin 24 at one end of the inner cavity of the threaded connecting pipe and on both sides of the threaded connecting pipe. A limiting ring of a blocking and limiting sleeve 23 is fixedly connected to the top of the connecting pipe surface. A handwheel is fixedly connected to the end of the screw 22 away from the extrusion block 21. The surface of the handwheel is provided with anti-slip texture. Both the loading robot 32 and the unloading robot 33 include a servo motor 331. The output shaft of the servo motor 331 is fixedly connected to a connecting seat 332. The other end of the connecting seat 332 is fixedly connected to a hydraulic telescopic rod 333. The bottom of the hydraulic telescopic rod 333 is fixedly connected to a vacuum adsorption plate 334. A valve is connected to the top of the vacuum adsorption plate 334. A pipe 335 is connected to the top of the vacuum adsorption plate 334 through a vacuum hose. The other end of the pipe 335 passes through to the top of the connecting seat 332 and is connected to the vacuum pump 31 through a vacuum hose.

[0032] In this embodiment: the through hole 15 ensures no interference during punching; the bottom waste receiving box facilitates waste collection; the controller 4 integrates a PLC system, supporting parameter programming and fault diagnosis; the threaded connecting pipe and the hydraulic telescopic rod are threaded together, providing a reliable mechanical connection; the hexagonal connecting plate facilitates quick wrench positioning, improving the efficiency of manual pre-tightening in the initial stage of mold changing; the support screw block is welded to the outside of the moving groove 14, providing rigid support for the lead screw 22, reducing radial sway during threaded transmission, and ensuring the synchronous movement accuracy of the extrusion block 21; the pin 24 forms an interference fit after being inserted into the receiving groove 25, preventing mold rotational deviation; the anti-slip texture of the handwheel adopts a herringbone pattern design, enabling mold locking without tools, balancing labor saving and safety; the combination of the servo motor 331 and the hydraulic telescopic rod 333 achieves three-dimensional positioning of the adsorption plate; the vacuum hose is made of high-pressure resistant PU material; and the layout of the pipe 335 avoids interference with the movement of the robotic arm.

[0033] The implementation principle of this utility model is as follows: During use, the loading robot 32 is positioned above the workpiece via a servo motor 331. The hydraulic telescopic rod 333 descends, causing the vacuum adsorption plate 334 to adhere to the workpiece surface. The vacuum pump 31 is activated to create negative pressure to adsorb the workpiece. The robot arm moves along a preset trajectory, placing the workpiece at the positioning station directly above the through hole 15 of the frame 11. The hydraulic telescopic rod 12 drives the punching die 13 downwards. The punching die contacts the workpiece surface, and the system pressure rises to complete the punching. Waste material falls into the receiving box through the through hole 15. After processing, the punching die 13 resets, and the unloading robot 33 simultaneously grabs the finished workpiece and transfers it to the next process, forming parallel operations of loading / unloading and punching. This allows for more efficient processing. When changing the punching die 13, rotate the handwheel counterclockwise to loosen the screw 22 and the extrusion block 21. The limiting sleeve 23 falls under its own weight, exposing the receiving groove 25. Pull out the pin 24 to remove the old punching die 13. When installing the new punching die 13, align the threaded connecting pipe and screw in the hydraulic telescopic rod. After inserting the pin 24, rotate the handwheel clockwise. The extrusion block 21 will fit against the side wall of the moving groove 14 and lock. The limiting sleeve 23 will be squeezed upward to seal the receiving groove 25, completing the quick positioning and fixing. The controller 4 presets processing parameters for different workpieces, supports one-click switching of production modes, monitors vacuum adsorption pressure and hydraulic system oil temperature in real time, and automatically stops and alarms in case of abnormality to ensure the reliability of equipment operation.

[0034] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
