[0024] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] Figure 1-3 As one embodiment of the utility model, a punching and positioning tool for processing a carriage support seat comprises a base, a punching unit is provided on the upper surface of the base, and a positioning mechanism for positioning the support seat is provided on the upper surface of the base;

[0026] The positioning mechanism includes a positioning plate slidably connected to the upper surface of the base, a threaded rod rotatably connected to the inner cavity of the base, one end of the threaded rod passes through the side of the base and is fixed with a knob, a U-shaped frame with an upward opening is threadedly connected to the outer circumferential surface of the threaded rod, and the U-shaped frame and the base are slidably connected, and a fixing component for positioning the support seat is provided on the U-shaped frame.

[0027] In actual use, when punching the carriage support seat, the positioning plate is moved according to the position of the support seat that needs to be punched, so that the side of the positioning plate is in conflict with one side of the support seat, and after adjusting the position of the positioning plate, the position of the positioning plate is fixed by turning the bolt, and the support seat is placed on the U-shaped frame, and one side of the support seat is in contact with the side of the positioning plate, and the position of the U-shaped frame is adjusted again according to the punching position, and the threaded rod is rotated by turning the knob, thereby driving the U-shaped frame to slide on the base, so as to achieve precise adjustment of the punching position of the support seat, and the support seat is fixed by using a fixing component, and then the punching unit is controlled to perform punching on the support seat, so as to achieve fast and accurate punching of the support seat, thereby improving the efficiency and effect of the punching process.

[0028] More specifically, a sliding groove is provided on the upper surface of the base for the positioning plate to slide. The cross-section of the sliding groove is a trapezoid that is wide at the top and narrow at the bottom. A bolt is threadedly connected to the upper surface of the positioning plate. The end of the bolt passes through the positioning plate and is rotatably connected to a resistance block for positioning the positioning plate.

[0029] In actual use, after the positioning plate is moved to an appropriate position according to the punching position, the bolt is tightened to move its end downward. The abutment block and the bolt are rotationally connected and restricted by the slide groove, so that the abutment block moves downward. The shape of the abutment block is a trapezoid that is narrow at the top and wide at the bottom. When the abutment block moves to contact the inner wall of the slide groove, the friction between the abutment block and the inner wall of the slide groove is used to fix the position of the positioning plate, thereby positioning the reference position of the support seat.

[0030] More specifically, scale lines are provided on the upper surface of the base, and the scale lines are arranged along the sliding direction of the positioning plate to confirm the position of the positioning plate; in actual use, when the support seat is positioned and punched, the positioning plate is moved to an appropriate position according to the punching position, so that one side of the support seat is in conflict with the positioning plate. By setting scale lines on the base, the position of the positioning plate can be quickly and accurately located when the positioning plate is moved, thereby improving the accuracy and efficiency of the punching process.

[0031] Specifically, the fixing component includes an electric push rod fixed on two inner sides of the U-shaped frame, a fixing plate is fixed to the end of the electric push rod, and the fixing plate and the U-shaped frame are slidably connected.

[0032] In actual use, when the support seat needs to be fixed, the support seat is placed on the U-shaped frame, and the electric push rod is controlled to push the fixing plate to move. When the fixing plate moves to both sides of the support seat, the initial fixation of the support seat is achieved.

[0033] More specifically, a connecting piece is hinged on the side of the fixing plate. The connecting piece is in a U-shape with its opening facing the support seat, and positioning wheels are rotatably connected at both ends of the connecting piece to perform resistance positioning on the inclined surface of the support seat.

[0034] During actual use, when the support seat is fixed, the fixing plate is driven by the electric push rod to approach the support seat, so that the positioning wheel contacts the side of the support seat. By arranging a rotatable connecting piece on the side of the fixing plate, the positioning wheel can be adjusted accordingly according to the inclination of the side of the support seat when contacting the side of the support seat, so that the positioning wheel is in close contact with the side of the support seat, thereby realizing positioning punching of support seats of different shapes, thereby expanding the application range of the punching equipment.

[0035] More specifically, a drilling hole is provided on the bottom surface of the U-shaped frame, and the drilling hole is located at the center of the bottom surface of the U-shaped frame, and is used for the punching unit to perform punching processing on the support seat.

[0036] During actual use, when punching the support seat, the drill bit of the punching unit moves down to penetrate the support seat. By setting a drill hole on the bottom surface of the U-shaped frame, the drill bit of the punching unit can smoothly penetrate the support seat, and the drill hole is set at the center of the bottom surface of the U-shaped frame, so that the punching position of the support seat can be preliminarily located.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
