[0002] As a key connecting component in mechanical transmission, the pin is widely used in engineering machinery, automotive parts, agricultural equipment and other fields. The accuracy of its end hole directly affects the assembly stability and safety of use.

[0003] Currently, manual placement is often used in the process of drilling holes for pins. However, manual operation can easily lead to problems such as uneven pin ends and positioning deviations, resulting in insufficient drilling accuracy. This can cause excessive clearance or even failure to assemble during subsequent assembly, thus affecting product quality. Summary of the Invention

[0004] The purpose of this invention is to provide an adaptive alignment and hole-opening device for pin machining, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pin shaft machining adaptive alignment and hole-opening device, comprising a base plate and a mesh plate. A vertical plate is fixedly installed on one side of the base plate, and a driving component for providing driving force is provided on one side of the vertical plate. The driving component includes a servo motor, a drive roller, a belt, a transmission roller, and a fan. The output end of the servo motor is mounted on the drive roller. A belt is provided on the outer surface of the drive roller, and a transmission roller is installed above the drive roller. One end of the transmission roller is connected to a fan. A lead screw is installed in the middle of one end of the drive roller, and a slider is threaded on the outer surface of the lead screw. The mesh plate is fixedly installed on the top of the slider. An auxiliary limiting component is provided on one side of the base plate, and the auxiliary component includes an inner plate, a clamping plate, and a support plate. A clamping plate is installed on the outer surface of the inner plate, and support plates are installed on both sides of the bottom of the clamping plate. A pin shaft is installed on the surface of the clamping plate.

[0006] Furthermore, the clamping plate has a "V" shaped structure, and the clamping plate and the support plate form a triangular structure.

[0007] Furthermore, a slide rail is provided in the middle of the base plate, and a slider is slidably installed inside the slide rail.

[0008] Furthermore, an auxiliary component two is installed on top of the auxiliary component one, and the auxiliary component one and the auxiliary component two have the same structure.

[0009] Furthermore, a limiting component for longitudinal fixation is provided on one side of the auxiliary component two, and the limiting component includes a fixing plate, a hydraulic rod, a top plate and a connecting plate. The hydraulic rod is installed on the outer surface of the fixing plate, and the output end of the hydraulic rod is provided with a top plate. A connecting plate is installed on one side of the top plate.

[0010] Furthermore, one side of the connecting plate is fixedly connected to the base plate, and the base plate and the upright plate form an "L" shaped structure.

[0011] Furthermore, each of the four corners on one side of the upright plate is equipped with a slot, and a baffle is engaged inside the slot.

[0012] Furthermore, a guide assembly for auxiliary guidance is installed on the outer side of the base plate away from the upright plate. The guide assembly includes a guide plate, a connecting shaft, an adapter plate, and a connecting spring. Side plates are fixedly installed on both sides of the surface of the guide plate.

A connecting spring is installed on one side of the bottom outer surface of the guide plate, and the end of the connecting spring is fixedly connected to the bottom of the base plate.

[0013] This invention provides a self-adaptive alignment and hole-opening device for pin machining, which has the following advantages: 1. This invention achieves adaptive alignment of the pin shaft through the coordinated action of the servo motor, lead screw, slider, and mesh plate in the drive assembly. This ensures that the pin shaft ends are flush, avoids positioning deviations caused by manual placement, and guarantees drilling accuracy. At the same time, it drives the fan to rotate rapidly, automatically cleaning debris in the processing area, reducing the frequency of manual cleaning and lowering the labor intensity of operators. Auxiliary component one and auxiliary component two work together with the limiting component to achieve stable clamping of the pin shaft, preventing shaking during drilling and further improving processing quality. Moreover, the entire process is automated, greatly reducing manual intervention, effectively improving processing efficiency, and adapting to the needs of large-scale production.

[0014] 2. When the pin is transferred to the guide plate, the design of the connecting shaft and the adapter plate allows the guide plate to rotate around the connecting shaft due to the weight of the pin. The design of the connecting spring provides cushioning, making it easier for users to collect the pin, avoiding damage to the pin, and improving the product qualification rate.

[0017] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0018] like Figures 1-4As shown, a self-adaptive alignment and hole-opening device for pin machining includes a base plate 1, a vertical plate 2, a pin 3, a side plate 4, a limiting component 5, a fixing plate 501, a hydraulic rod 502, a top plate 503, a connecting plate 504, a baffle 6, an auxiliary component 1 7, an internal plate 701, a clamping plate 702, a support plate 703, a slot 8, a drive component 9, a servo motor 901, a drive roller 902, a belt 903, a transmission roller 904, a fan 905, a guide component 10, a guide plate 1001, a connecting shaft 1002, an adapter plate 1003, a connecting spring 1004, a mesh plate 11, a slide rail 12, a lead screw 13, a slider 14, and an auxiliary component 2 15. The vertical plate 2 is fixedly installed on one side of the base plate 1, and one side of the vertical plate 2 is provided with... A drive assembly 9 is provided to provide driving force. A slide rail 12 is provided in the middle of the base plate 1, and a slider 14 is slidably installed inside the slide rail 12. The drive assembly 9 includes a servo motor 901, a drive roller 902, a belt 903, a transmission roller 904, and a fan 905. The output end of the servo motor 901 is mounted on the drive roller 902. The belt 903 is provided on the outer surface of the drive roller 902, and the transmission roller 904 is mounted above the drive roller 902. One end of the transmission roller 904 is connected to the fan 905. A lead screw 13 is mounted in the middle of one end of the drive roller 902, and the slider 14 is threaded on the outer surface of the lead screw 13. A mesh plate 11 is fixedly installed on the top of the slider 14. An auxiliary limiting device is provided on one side of the base plate 1. Component 1 7, and auxiliary component 1 7 includes an inner plate 701, a clamping plate 702, and a support plate 703. Auxiliary component 2 15 is installed on top of auxiliary component 1 7, and auxiliary component 1 7 and auxiliary component 2 15 have the same structure. The clamping plate 702 is installed on the outer surface of the inner plate 701, and support plates 703 are installed on both sides of the bottom of the clamping plate 702. The clamping plate 702 has a "V" shaped structure, and the clamping plate 702 and the support plate 703 form a triangular structure. A pin 3 is installed on the surface of the clamping plate 702. First, the pin 3 is pre-placed on the outer surface of the clamping plate 702. Then, the servo motor 901 is activated. The design of the servo motor 901 can drive the lead screw 13 to rotate. The rotation of the lead screw 13 can drive the slider 1. 4 and the screen plate 11 are limited to the slide rail 12 for horizontal movement. The design of the screen plate 11 can keep the end of the pin 3 flush with the end of the clamping plate 702, avoiding uneven positions when the pin 3 is manually placed. It can adaptively align the hole. After the hole is opened, when the pin 3 is removed, the design of the servo motor 901 can drive the active roller 902, belt 903 and transmission roller 904 to rotate. One end of the transmission roller 904 is connected to the fan 905 shaft, thereby driving the fan 905 to rotate. The difference in diameter between the active roller 902 and the transmission roller 904 can drive the fan 905 to rotate quickly, which facilitates auxiliary dust blowing and cleaning of the processing area on one side of the base plate 1 and reduces the frequency of manual periodic cleaning.

[0019] like Figure 2 and Figure 5 As shown, a limiting component 5 for longitudinal fixation is provided on one side of auxiliary component 2 15. The limiting component 5 includes a fixing plate 501, a hydraulic rod 502, a top plate 503, and a connecting plate 504. The hydraulic rod 502 is installed on the outer surface of the fixing plate 501, and the top plate 503 is provided at the output end of the hydraulic rod 502. The connecting plate 504 is installed on one side of the top plate 503. One side of the connecting plate 504 is fixedly connected to the bottom plate 1. The bottom plate 1 and the vertical plate 2 form an "L" shaped structure. After the pin 3 is initially aligned at both ends, the design of the fixing plate 501 and the hydraulic rod 502 can drive the top plate 503 and the connecting plate 504 to move accordingly, thereby driving the auxiliary component 2 15 to move downward accordingly, so that the pin is between the two sets of clamping plates 702, maintaining the stability of the pin 3 when the hole is opened. The four corners of one side of the vertical plate 2 are all equipped with slots 8, and the slots 8 are fitted with baffles 6. A guide assembly 10 for auxiliary guidance is installed on the side of the outer side away from the upright plate 2. The guide assembly 10 includes a guide plate 1001, a connecting shaft 1002, an adapter plate 1003, and a connecting spring 1004. Side plates 4 are fixedly installed on both sides of the surface of the guide plate 1001. A connecting shaft 1002 is installed on both sides of one end of the guide plate 1001. An adapter plate 1003 is rotatably installed at the end of the connecting shaft 1002. A connecting spring 1004 is installed on one side of the bottom outer surface of the guide plate 1001. The end of the connecting spring 1004 is fixed to the bottom of the base plate 1. When the pin 3 is transferred into the guide plate 1001, the design of the connecting shaft 1002 and the adapter plate 1003 allows the guide plate 1001 to rotate around the connecting shaft 1002 due to the gravity of the pin 3. The design of the connecting spring 1004 provides cushioning, making it easy for the user to collect the pin 3.

[0020] In summary, this self-adaptive alignment and hole-opening device for pin machining firstly... Figures 1-5In the structure shown, during use, the pin 3 is first placed on the outer surface of the clamping plate 702. The servo motor 901 in the drive assembly 9 is then started. The output of the servo motor 901 drives the active roller 902 to rotate. Since the middle of one end of the active roller 902 is fixedly connected to the lead screw 13, the lead screw 13 rotates synchronously with the active roller 902. The slider 14, threadedly connected to the outer surface of the lead screw 13, is limited within the slide rail 12 in the middle of the base plate 1 and cannot rotate synchronously with the lead screw 13. Therefore, under the threaded driving force of the lead screw 13, the top-fixed mesh plate 11 moves horizontally along the slide rail 12. During the movement of the mesh plate 11, its end gradually approaches the pin 3 placed on the clamping plate 702 until the mesh plate 11 and the end of the pin 3 are in contact, keeping the end of the pin 3 to be processed flush. This completely solves the problem of uneven positions when manually placing the pin 3, achieving self-adaptive alignment of the pin 3 and ensuring precise subsequent hole drilling. After alignment is completed, the pin 3 is then... The longitudinal fixation of the pin 3 ensures its stability during the drilling process. An auxiliary component 2 15 with the same structure is installed above the auxiliary component 1 7. The hydraulic rod 502 in the limiting component 5 is activated. The hydraulic rod 502 is fixed to the fixed plate 501, and its output end pushes the top plate 503 to move. One side of the top plate 503 is fixedly connected to the connecting plate 504, while the other end of the connecting plate 504 is fixed to the bottom plate 1. Therefore, the driving force of the hydraulic rod 502 will cause the auxiliary component 2 15 to move down synchronously with the top plate 503 until the clamping plate 702 of the auxiliary component 2 15 precisely aligns with the clamping plate 702 of the auxiliary component 1 7, firmly clamping the pin 3 between the two sets of clamping plates 702. This achieves longitudinal limiting and fixation of the pin 3, preventing it from shaking or shifting during drilling and ensuring drilling accuracy. After fixing, the pin 3 can be drilled. After the drilling operation is completed, the processing area is first cleaned by blowing off dust, eliminating the need for manual cleaning. At this point, the servo motor 901 can be restarted. The servo motor 901 drives the active roller 902 to rotate. The active roller 902 drives the upper transmission roller 904 to rotate via the belt 903 on its outer surface. Since one end of the transmission roller 904 is fixedly connected to the shaft of the fan 905, the fan 905 rotates synchronously with the transmission roller 904. By utilizing the difference in diameter between the active roller 902 and the transmission roller 904, the fan 905 can rotate rapidly. The airflow generated by the fan 905 directly acts on the processing area on one side of the base plate 1, blowing away metal debris and dust generated during the opening process, effectively reducing the frequency of manual cleaning and improving the ease of maintenance of the device. Finally, the pin 3 is collected. The processed pin 3 is removed from between the two sets of clamping plates 702 and transferred to the guide plate 1001 of the guide assembly 10. Side plates 4 are fixedly installed on both sides of the surface of the guide plate 1001 to prevent the pin 3 from falling during transportation. After the pin 3 is placed on the guide plate 1001, under its own weight, the guide plate 1001 rotates around the connecting shaft 1002 as the rotation center. At the same time, the connecting spring 1004 at the bottom is stretched. The elastic force of the connecting spring 1004 is used to buffer the impact and prevent the pin 3 from being damaged by gravity. The rotation of the guide plate 1001 can smoothly guide the pin 3 to the designated collection position, which is convenient for users to collect in a unified manner, completing the entire process of processing the pin 3.
