Description

Technical Field

[0001] This utility model relates to the field of punching tooling technology, specifically a punching tooling for car door guide rails. Background Technology

[0002] Utility model patent CN219188312U discloses a door guide rail punching device, including a mounting base plate. The mounting base plate contains a lifting deburring mechanism, and a processing table is mounted on its top surface. A groove is carved into the top of the processing table, and a debris cleaning mechanism is connected to the groove via an electric push mechanism. A mounting bracket is mounted on the top of the processing table. An electro-hydraulic push rod and a lifting plate are used as driving components, extending the deburring end through a long slot into the groove. A drive motor and drive shaft serve as the central driving mechanism, driving the deburring roller to clean the punched area of ​​the door guide rail. Compared to prior art, this invention adds a structure for deburring the punched area after punching, greatly improving practicality. The sliding method, linking the electric push rod and the slider, moves the moving plate and the debris falling from the punched area in the cleaning groove laterally, making it easier for workers to clean the debris.

[0003] However, the device has certain shortcomings in use. It is not easy to adjust and control the limit of guide rails of different widths, which makes it easy for the guide rails to shift position during movement, causing the punching position to shift left and right. At the same time, when the device is conveying the guide rails, friction during the conveying process can easily cause slippage between the guide rails and the conveyor belt, affecting the conveying stability of the guide rails. Utility Model Content

[0004] The purpose of this utility model is to provide a door guide rail punching fixture, which solves the problems of the device being inconvenient to adjust and control the limit of guide rails of different widths, which easily causes positional deviation during the movement of the guide rail, resulting in left and right deviation of the punching position. At the same time, when the device transports the guide rail, friction during the transport process can easily cause slippage between the guide rail and the conveyor belt, affecting the transport stability of the guide rail.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a punching fixture for a car door guide rail, comprising a base plate, a guide post fixedly connected to the upper end of the base plate, a frame slidably connected to the outer side of the guide post, a top spring provided on the outer side of the guide post, one end of the top spring being fixedly connected to the base plate, the other end of the top spring being fixedly connected to the frame, a conveyor belt provided on the frame, a guiding mechanism provided on the frame, a limit mechanism provided on the frame, a bracket fixedly connected to the upper end of the base plate, a punching machine provided on the bracket, and a support platform fixedly connected to the upper end of the base plate, the support platform being slidably connected to the frame.

[0006] Preferably, the guiding mechanism includes a slide bar, which is slidably connected inside the frame. A support plate is fixedly connected to the lower end of the frame, and a motor is fixedly mounted on the surface of the support plate. The motor's shaft passes through the support plate and is rotatably connected to it. A bidirectional screw is fixedly connected to the end of the motor's shaft. The bidirectional screw is rotatably connected to the support plate, and a pressure plate is threadedly connected to the outer side of the bidirectional screw. A guide rod is fixedly connected to the surface of the pressure plate, and the guide rod is slidably connected to the slide bar. A spring is provided on the outer side of the guide rod. By driving the bidirectional screw to rotate and the pressure plate to perform threaded movement, the spring elastically compresses the slide bar, which in turn allows the wheel seat to drive the guide wheel to move. This allows the device to limit and guide guide rails of different widths, preventing lateral displacement of the punching position.

[0007] Preferably, a wheel seat is fixedly connected to the upper end of the slide bar, and a guide wheel is rotatably connected inside the wheel seat. The wheel seat supports the guide wheel.

[0008] Preferably, one end of the spring is fixedly connected to the pressure plate, and the other end of the spring is fixedly connected to the slide bar. By setting the spring, the slide bar is elastically compressed.

[0009] Preferably, the limiting mechanism includes a mounting frame, with the upper end of the frame fixedly connected to the mounting frame. A roller frame is slidably connected inside the mounting frame, and a pressure roller is rotatably connected inside the roller frame. A lead screw is mounted inside the mounting frame via bearings, and a screw cylinder is threadedly connected to the outer side of the lead screw. A guide cylinder is movably connected to the outer side of the screw cylinder, and the guide cylinder is fixedly connected to the roller frame. A compression spring is installed inside the guide cylinder. By rotating the lead screw and screw cylinder to perform threaded movement, the compression spring elastically compresses the roller frame, causing the pressure roller to press the guide rail onto the conveyor belt. A top spring supports the frame, facilitating the separation of the guide rail from the support platform during transport and ensuring the stability of the guide rail's transport.

[0010] Preferably, a guide pin is fixedly connected to the surface of the screw barrel, and the guide pin and the guide barrel are slidably connected. By providing the guide pin, relative rotation between the screw barrel and the guide barrel is prevented.

[0011] Preferably, one end of the compression spring is fixedly connected to the screw cylinder, and the other end of the compression spring is fixedly connected to the roller frame. By setting the compression spring, the roller frame is elastically compressed.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a motor to drive a bidirectional screw to rotate and a pressure plate to make a threaded motion, which in turn causes a spring to elastically compress a slide bar, which in turn causes the wheel seat to drive the guide wheel to move. This allows the device to limit and guide guides with different widths, preventing the punching position from shifting to the left or right.

[0013] 2. This utility model uses the rotation of the lead screw and the screw barrel to make a spiral motion, which causes the spring to elastically squeeze the roller frame, and then the pressure roller squeezes the guide rail onto the conveyor belt. The top spring supports the frame, which makes it easy to separate the guide rail from the support platform during the conveying process, thus ensuring the conveying stability of the guide rail.

[0018] Please see Figures 1-3The guiding mechanism 6 includes a slide bar 61, which is slidably connected inside the frame 3. A wheel seat 62 is fixedly connected to the upper end of the slide bar 61, and a guide wheel 63 is rotatably connected inside the wheel seat 62. The wheel seat 62 supports the guide wheel 63. A support plate 64 is fixedly connected to the lower end of the frame 3. A motor 65 is fixedly mounted on the surface of the support plate 64. The shaft of the motor 65 passes through the support plate 64 and is rotatably connected to it. A double-ended screw 66 is fixedly connected to the end of the shaft of the motor 65. The double-ended screw 66 is rotatably connected to the support plate 64, and a pressure plate 67 is threadedly connected to the outer side of the double-ended screw 66. A guide rod 68 is fixedly connected to the surface of the pressure plate 67. The guide rod 68 and the slide bar 61 are slidably connected. A spring 69 is provided on the outside of the guide rod 68. One end of the spring 69 is fixedly connected to the pressure plate 67, and the other end of the spring 69 is fixedly connected to the slide bar 61. By setting the spring 69, the slide bar 61 is elastically compressed. The motor 65 drives the bidirectional screw 66 to rotate and the pressure plate 67 to make threaded movements, thereby causing the spring 69 to elastically compress the slide bar 61. This allows the wheel seat 62 to drive the guide wheel 63 to move, thereby enabling the device to limit and guide guide rails of different widths and prevent the punching position from shifting to the left or right.

[0019] Please see Figure 1 , Figure 2 , Figure 4 The limiting mechanism 7 includes a mounting frame 71. The upper end of the frame 3 is fixedly connected to the mounting frame 71. A roller frame 72 is slidably connected inside the mounting frame 71. A pressure roller 73 is rotatably connected inside the roller frame 72. A lead screw 74 is mounted inside the mounting frame 71 via a bearing. A screw barrel 75 is threadedly connected to the outside of the lead screw 74. A guide cylinder 76 is movably connected to the outside of the screw barrel 75. The guide cylinder 76 is fixedly connected to the roller frame 72. A guide pin 77 is fixedly connected to the surface of the screw barrel 75. The guide pin 77 is slidably connected to the guide cylinder 76. By setting the guide pin 77, the screw barrel is prevented from sliding. 75 and guide cylinder 76 rotate relative to each other. Inside guide cylinder 76 is a compression spring 78. One end of compression spring 78 is fixedly connected to screw cylinder 75, and the other end of compression spring 78 is fixedly connected to roller frame 72. By setting compression spring 78, roller frame 72 is elastically compressed. By rotating screw 74 and screw cylinder 75 to make threaded movement, compression spring 78 elastically compresses roller frame 72, thereby causing pressure roller 73 to press guide rail onto conveyor belt 5. And the top spring 4 supports frame 3, thereby making it easy to separate guide rail from support platform 10 during conveying, ensuring the conveying stability of guide rail.

[0020] The specific implementation process of this utility model is as follows: In use, the guide rail is placed on the conveyor belt 5, and the motor 65 is started. The motor 65 drives the bidirectional screw 66 to rotate. The rotation of the bidirectional screw 66 and the screw plate 67 make a threaded movement, which in turn causes the screw plate 67 to move. The movement of the screw plate 67 compresses the spring 69, which in turn causes the spring 69 to elastically compress the slide bar 61, which in turn causes the slide bar 61 to move. The slide bar 61 drives the wheel seat 62 to move, which in turn drives the guide wheel 63 to move. This causes the guide wheel 63 to contact the side of the guide rail, so that the device can limit and guide guide rails of different widths, preventing the punching position from moving left or right. The screw 74 is rotated, and the screw 74 rotates and the screw barrel 75 makes a threaded motion, which in turn causes the screw barrel 75 to move. The movement of the screw barrel 75 compresses the compression spring 78, which in turn causes the compression spring 78 to elastically compress the roller frame 72, which in turn causes the roller frame 72 to drive the pressure roller 73 to press the guide rail onto the conveyor belt 5. The guide rail is transported by the conveyor belt 5. The punching machine 9 is started, and the punching machine 9 punches holes in the guide rail. The guide rail moves down, which drives the conveyor belt 5 to move. The conveyor belt 5 drives the frame 3 to move. The movement of the frame 3 compresses the top spring 4, which is elastically compressed. At this time, the guide rail and the support table 10 come into contact, which makes the guide rail punched.
