Background Art

[0002] In the existing sheet metal processing, especially the drilling processing of anti-dropout pin structural parts, due to the lack of traditional clamping methods and positioning accuracy, the problems of hole position deviation and substandard verticality often occur, which seriously affects the quality and installation accuracy of the product. Especially in the anti-dropout pin structure, the deviation of the drilling will directly affect its installation and use effect. Therefore, how to develop a drilling auxiliary positioning device that can solve these problems is particularly important. Summary of the invention

[0025] See also Figures 1 to 4 The present invention provides a pin-drop-proof drilling positioning auxiliary device, comprising: A positioning seat 1 is provided with a horizontally penetrating axial positioning hole 2 inside thereof for placing the anti-dropping pin to be processed; The drill sleeve 3 is vertically fixed to the top surface of the positioning seat and its bottom hole intersects with the positioning hole; The horizontal slot is arranged in the positioning seat at a position corresponding to the anti-dropout pin slot 7 of the anti-dropout pin 6, and together with the anti-dropout pin slot, forms a positioning slot; it can be understood that the horizontal slot extends to the axial positioning hole, and can form a positioning slot with the anti-dropout pin slot after the anti-dropout pin is inserted into the positioning hole; The horizontal card slot baffle 5 is inserted into the positioning card slot and cooperates with the positioning card slot with a slight gap; The chip removal groove 4 is arranged inside the positioning seat and is located just below the bottom hole of the drill sleeve and above the horizontal slot baffle.

[0026] One end of the anti-drop pin has an anti-drop pin slot, and the walls on both sides of the anti-drop pin slot need to be drilled; see Figure 3 The anti-pin-off structure shown.

[0027] Specific positioning of anti-drop pin drilling: Insert the anti-dropout pin into the positioning hole horizontally, keeping the anti-dropout pin slot in a horizontal state; The horizontal slot baffle is inserted in the horizontal slot, and the horizontal slot baffle in the middle part is inserted into the anti-dropout pin slot. The horizontal slot baffle forms a micro-gap with the anti-dropout slot and the horizontal slot to prevent the anti-dropout pin from rotating during processing; the drill bit is guided to drill through the carbide drill sleeve to ensure the verticality of the drilling; the chips generated by cutting are discharged smoothly through the chip groove to avoid chip accumulation.

[0028] The anti-dropout pin drilling positioning auxiliary device of the present application can improve the drilling accuracy, avoid hole offset and angle deviation, and have the advantages of smooth chip removal; specifically, the synergistic effect of the carbide drill sleeve and the anti-dropout pin slot baffle ensures the verticality and hole position accuracy during the drilling process, significantly improving the drilling accuracy; the horizontal slot baffle prevents the angle deviation of the anti-dropout pin slot through precise fixed design, ensures the verticality of the drilling, and avoids the offset problem in the traditional drilling method; and the design of the chip removal groove ensures the smooth discharge of chips, avoids the jamming phenomenon caused by chip accumulation, and improves the stability and efficiency of the processing process. The anti-dropout pin drilling positioning device of the present application can significantly improve the processing quality of the anti-dropout pin component and the assembly accuracy of the product by effectively solving the hole position offset and verticality problems in traditional drilling processing, thereby improving the quality and reliability of the overall product.

[0029] Furthermore, the horizontal slot baffle and the positioning slot have a micro-gap fit. Preferably, the micro-gap tenon fits. The gap value of the micro-gap fit is controlled within the range of 0.05-0.15 mm. The micro-gap value can also be selected according to actual needs; the micro-gap fit enhances the fixing force, avoids the angle change of the anti-dropping pin during the drilling process, ensures the verticality of the drilling, and effectively prevents the hole position from shifting.

[0030] Furthermore, a chip removal groove is provided through the positioning seat, and the thickness of the chip removal groove is higher than the thickness of the anti-dropout pin wall edge of the anti-dropout pin slot. The design of the chip removal groove ensures that the chips generated during the cutting process can be discharged smoothly, avoids the processing error caused by chip blockage, and improves the stability and efficiency of the processing process.

[0031] Furthermore, the drill sleeve is made of carbide, and the bottom hole of the drill sleeve is processed by integral wire cutting to ensure the verticality with the axial positioning hole. The carbide drill sleeve and the bottom hole processed by the integral wire cutting process ensure the verticality and centering accuracy of the drill hole, and significantly improve the drilling accuracy.

[0032] Furthermore, the positioning seat includes a horizontal bottom plate and a positioning block arranged on one side of the top of the horizontal bottom plate; the axial positioning hole, the drill sleeve, the horizontal slot, the chip removal groove and the horizontal slot baffle are all arranged on the positioning block; The other side portion of the horizontal bottom plate on the side of the positioning block forms a low area for avoiding steps.

[0033] Along the axial direction of the axial positioning hole, the length of the horizontal slot blocking piece is greater than the size of the horizontal slot, so that a portion of the horizontal slot blocking piece extends to the low area of ​​the avoidance step. The size of the horizontal slot blocking piece can also be selected to be flush with the positioning slot and not extend to the low area of ​​the avoidance step.

[0034] The low area of ​​the avoidance step serves as an avoidance gap space, which makes it easy to check the installation status of the anti-dropping pin of the positioning block, and is also conducive to the insertion operation of the horizontal slot baffle; and the low area of ​​the avoidance step serves as an extended part, which can also be used as a connecting ear plate, and a threaded lock hole is set to fix it on the processing table with bolts.

[0035] Furthermore, the positioning block is integrally connected to the horizontal bottom plate to form an integral positioning seat. The positioning block is integrally connected to the horizontal bottom plate to enhance the stability of the integral positioning seat structure.
