[0004] To solve the above technical problems, the technical solution adopted by the utility model is: a punching device for turbocharger housing processing, including a processing table, support legs are arranged at the bottom of the processing table, a plurality of U-shaped fixing frames distributed in the left-right direction are detachably arranged at the top of the processing table, placing grooves for clamping and placing the turbocharger housing are respectively arranged at the tops of the plurality of fixing frames, through holes communicating with the plurality of placing grooves and corresponding to the positions of the clamping holes on the turbocharger housing are respectively arranged at the tops of the plurality of fixing frames, top material holes communicating with the plurality of placing grooves are respectively arranged at the tops of the plurality of fixing frames, cross plates are respectively slidably arranged between the left and right ends of the plurality of fixing frames, a plurality of springs are arranged between the top of the cross plate and the bottom wall of the top of the fixing frame, connecting sliding sleeves adapted to the corresponding side ends of the fixing frame are respectively arranged at the left and right ends of the cross plate, at least one connecting sliding sleeve corresponding to the same fixing frame is also provided with a limit bolt that can abut against the outer side wall of the connecting rod to fix the connection between the connecting sliding sleeve and the fixing frame, top material rods adapted to the corresponding top material holes are respectively arranged at the tops of the plurality of cross plates, and a mobile punching module is also arranged at the top of the processing table.

[0005] As a further improvement of the utility model, the plurality of limit bolts are all hand-tightening bolts.

[0006] As a further improvement of the present utility model, the mobile punching module includes vertical rods respectively arranged at the top corners of the processing table. The tops of the four vertical rods are jointly provided with a top plate. The left and right side ends at the bottom of the top plate are respectively provided with first linear slides running in the front-rear direction.

Then, while the punching process is ongoing, the punched turbine casings and the corresponding fixing frames can be removed from the processing table. Subsequently, the limit bolts can be loosened. Under the contraction and pulling action of multiple springs, multiple ejector rods will move first, thus ejecting the upper end of the turbine casing out of the placement groove, enabling the user to conveniently and quickly remove the turbine casing from the top of the fixing frame. After that, the cross plate and multiple ejector rods can be moved downward again, driving the springs to be stretched again. Subsequently, the connection between the connecting sleeve and the side end of the fixing frame can be fixed again through the limit bolts. Then, a new batch of turbine casings can be placed into the placement grooves at the top of the fixing frame. Next, the fixing frame and the turbine casings can be placed on the processing table. Therefore, the technical solution of the present application can not only meet the basic requirements for punching the turbine casings, but also quickly complete the replacement of the punched turbine casings and the turbine casings to be punched, enabling the user not to pause the punching process for a long time to wait for the feeding and loading of the turbine casings, thereby improving the overall efficiency of punching multiple turbine casings.

[0014] Third, through the cooperation of the connecting bolts and the threaded connection holes, the flexible fixing of the mounting sleeve and the punching drill bit can be achieved.

[0015] Fourth, through the anti-slip pad, it can be avoided that the device easily deviates during the working process; through the cooperation of the retaining ring and the connecting card hole, the flexible fixing of the fixing frame and the processing table can be achieved.
