[0035] like Figures 1-4 As shown, it illustrates a punching machine positioning fixture according to an embodiment of the present disclosure, comprising:
[0036] The fixed base 1 and a pair of base frames 2 are fixed at both ends of the bottom of the fixed base 1;
[0037] Inner support component 4 is mounted on the fixed base 1;
[0038] A pair of rectangular slots 3 and an inlet component 5, the rectangular slots 3 are opened at both ends of the surface of the fixed base 1, and the inlet component 5 is set in the rectangular slots 3;
[0039] The inner support assembly 4 includes an outer frame 4-1, which is inserted into the surface of the fixed base 1. A bottom cavity 4-2 is formed inside the fixed base 1. Several stamping holes 4-3 are formed on the top of the bottom cavity 4-2 and on both surfaces of the outer frame 4-1. A fixing rod 4-4 is provided at one end of the fixed base 1. A pair of splicing rods 4-5 are rotatably connected to one end of the fixed base 1 via a pin. A main frame 4-6 is provided at one end of the fixing rod 4-4, and a secondary frame 4-7 is provided at one end of the splicing rod 4-5. The secondary frames 4-7 are attached to both sides of the main frame 4-6. -6 is fixedly connected to the sub-frame 4-7 by bolts. The main frame 4-6 and the sub-frame 4-7 are internally connected by an inner support plate 4-8. One end of the inner support plate 4-8 is fixedly connected to the sub-frame 4-7 by bolts. One end of the inner support plate 4-8 is located inside the outer frame 4-1. A pair of fixing blocks 4-9 are provided on the surface of the fixing seat 1. A pair of pads 4-10 are rotatably connected to the surface of the fixing seat 1 by a pin. A spring 4-11 is connected between the pads 4-10 and the fixing blocks 4-9. The pads 4-10 are attached to the bottom surface of the inner support plate 4-8.
[0040] In some examples, an inner support assembly 4 is designed to achieve the effect of clamping the frame and supporting the interior. The outer frame 4-1 of the inner support assembly 4 is tightly inserted into the surface of the fixed base 1, and the two sides are connected and stable. The fixed base 1 has a bottom cavity 4-2 inside. Several stamping holes 4-3 are evenly distributed on the top of the bottom cavity 4-2 and the two surfaces of the outer frame 4-1. In practical applications, these stamping holes, in conjunction with the stamping process, can enhance the connection strength between the outer frame 4-1 and the fixed base 1 and prevent loosening. A fixing rod 4-4 is provided at one end of the fixed base 1. A pair of splicing rods 4-5 are rotatably connected to both sides of the fixing rod 4-4 by pins. This structure allows the splicing rods 4-5 to rotate flexibly, which can easily adapt to the needs of different shaped frames. One end of the fixing rod 4-4 is connected to the main frame 4-6, and one end of the splicing rod 4-5 is connected to the sub-frame 4-7. 7 is tightly fitted to both sides of the main frame 4-6 and fixed with bolts, which facilitates disassembly and maintenance and ensures the reliability of the connection. The main frame 4-6 and the sub-frame 4-7 are fitted with inner support plates 4-8, which are also fixed with bolts, making it easy to disassemble as needed. The inner support plates 4-8 are in direct contact with the inside of the frame and play a key supporting and clamping role. The surface of the fixing seat 1 is provided with a pair of fixing blocks 4-9, and a pair of pads 4-10 are rotatably connected by a pin. A spring 4-11 is connected between the fixing blocks 4-9 and the pads 4-10. The pads 4-10 are attached to the bottom surface of the inner support plate 4-8. The spring 4-11 can provide cushioning. The pads 4-10 can prevent the inner support plate 4-8 from bending downward due to excessive length, avoiding affecting the insertion of the frame and ensuring that the inner support assembly 4 stably clamps and supports the frame, ensuring the smooth operation of the entire process.
[0041] like Figures 1-4 As shown, this embodiment proposes an inlet component 5, which includes several round rods 5-1, all of which are fixed in a rectangular groove 3. A slider 5-2 is slidably connected to a fixed rod 4-4. A tension spring 5-3 is connected to the inner side of the rectangular groove 3 for the slider 5-2. A drive motor 5-4 is provided at the bottom of the slider 5-2. A rotating wheel 5-5 is provided at the output end of the drive motor 5-4. An inlet plate 5-6 is provided on the upper surface of the slider 5-2. The inlet plate 5-6 is fixedly connected at an inclined angle.
[0042] In some examples, to achieve the effect of quickly inserting the frame into the positioning punch, an inlet component 5 is designed, including several round rods 5-1 fixed in a rectangular groove 3. A slider 5-2 is slidably connected to the round rods 5-1. The slider 5-2 is connected to the inner side of the rectangular groove 3 by a tension spring 5-3. A drive motor 5-4 is provided at the bottom of the slider 5-2. A rotating wheel 5-5 is provided at the output end of the drive motor 5-4. The two rotating wheels 5-5 can be attached to the two sides of the frame by the tension of the tension spring 5-3. After being attached, the frame can be moved by the rotating wheels 5-5. An inlet plate 5-6 is provided on the upper surface of the slider 5-2 and fixedly connected at an inclined angle to facilitate the opening of the two rotating wheels 5-5 when the frame is inserted.
[0043] For example, such as Figure 2 As shown, the base frame 2 has an overall L-shaped structure, and several fixing holes 6 are opened on the surface of the base frame 2.
[0044] In some examples, the L-shaped structure increases the support strength at the bottom, and the fixing hole 6 facilitates connection to the punching machine via fasteners.
[0045] For example, such as Figure 3 As shown, the inner support plates 4-8 have an overall L-shaped structure.
[0046] In some examples, an L-shaped structure is used to increase the connection strength at one end of the inner support plate 4-8.
[0047] For example, such as Figure 1 As shown, both sides of the bottom cavity 4-2 are open structures.
[0048] In some examples, the open structure facilitates the removal of waste material from the stamping process.
[0049] For example, such as Figure 2 As shown, a pair of splicing rods 4-5 can rotate 30° to each side.
[0050] In some examples, the panels can be opened to the sides by rotating at a 30° angle, facilitating separation from the inner support plates 4-8.
[0051] In practical use: To achieve the effect of quickly guiding the frame into the positioning punch, a carefully designed guiding component 5 is used. In this component, several round rods 5-1 are firmly fixed in the rectangular groove 3, forming the basic structure of the entire guiding method. On the round rods 5-1, the sliders 5-2 can slide and are connected to the inner side of the rectangular groove 3 through tension springs 5-3. The tension springs 5-3 are normally in a stretched state. The drive motor 5-4 installed at the bottom of the slider 5-2 is the power source for moving the frame. The rotating wheel 5-5 at its output end rotates under the drive of the drive motor 5-4. When the frame approaches, the tension spring 5-3 releases its elastic potential energy, causing the two rotating wheels to move. The rotating wheels 5-5 are tightly fitted to both sides of the frame. At this time, the drive motor 5-4 starts, and the rotating wheels 5-5 drive the frame to move by friction, realizing the initial conveying of the frame. The guide plate 5-6 set on the upper end of the slider 5-2 is fixedly connected at an inclined angle. When the frame contacts the guide plate 5-6, the inclined guide plate 5-6 will generate an outward component force on the frame, easily opening the two rotating wheels 5-5, so that the frame can smoothly enter between the two rotating wheels 5-5. After that, the rotating wheels 5-5 drive the frame to move to the positioning punch position, which effectively improves the efficiency of the frame to enter the positioning punch and ensures the smooth progress of the work.
[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
