[0037] The support rear plate 11 is fixedly mounted on the top rear end of the storage cavity 29, the support base frame 21 is fixedly mounted on the top front end of the storage cavity 29, the connecting rope 35 is fixedly connected to the winding wheel 22, the delivery pipe 33 is respectively connected to the bottom end of the second oil storage cavity 31 and the front end of the first oil storage cavity 27, the front end of the rack 9 is vertically aligned with the rear end of the second gear 24, the top and bottom of the opposite side ends of the first alignment key 8 and the second alignment key 18 are both inclined at 45°, through holes are opened on both sides of the second oil storage cavity 31, and the top of the filter 38 is flush with the inner bottom end of the through hole, the bottom end of the scraper 32 is in contact with the top surface of the filter 38, the transmission ratio of the second gear 24 to the first gear 23 is 1:10, the inner bottom ends of the first oil storage cavity 27 and the second oil storage cavity 31 are both installed with guide inclined plates, the interior of the air cylinder 16 is arranged in a hollow state, and a closed cavity is formed between the first piston rod 15, the air cylinder 16 and the second piston rod 17.

[0038] The working principle of embodiment 1 is as follows: when in use, the stamping oil is first poured into the interior of the first oil storage cavity 27. Through the setting of the first return spring 19, the displacement cross frame 26 can be squeezed to move closer to the interior of the first oil storage cavity 27, so that the sealing plug 28 can block the interior of the delivery pipe 20. Subsequently, the chain pin 2 can be placed in the interior of the clamping fixture 3 to achieve the clamping and positioning of the chain pin 2, so that the chain pin 2 is vertically aligned with the punching head 10, and then the hydraulic equipment 6 is started to drive the support base plate 7 and the punching head 10 to move downward at the same time. At this time, when the support base plate 7 moves downward, it can drive the first alignment key 8 to contact the second alignment key 18. The top and bottom ends of the opposite side ends of the first alignment key 8 and the second alignment key 18 are inclined at 45 degrees, so that The smoothness of the first alignment key 8 passing through the second alignment key 18 can be improved. When the first alignment key 8 squeezes the second alignment key 18 and moves to the extreme position, the second piston rod 17 can be driven to be completely inserted into the interior of the air cylinder 16, so that the first piston rod 15 can drive the displacement cross frame 26 to move toward the end away from the second alignment key 18, so that the displacement cross frame 26 can drive the sealing rubber plug 28 to be drawn out from the interior of the delivery pipe 20. At this time, the delivery pipe 20 is interconnected with the interior of the first oil storage cavity 27, so that the stamping oil in the first oil storage cavity 27 can flow out through the delivery pipe 20, and the end of the delivery pipe 20 away from the first oil storage cavity 27 is tilted and aligned with the punching head 10, so that the delivery pipe 20 can drain the stamping oil to the outer ring of the punching head 10, and, The punching oil can drip along the outer ring of the punching head 10 onto the surface of the chain pin 2. Then, when the punching head 10 contacts the chain pin 2, punching can be performed. At the same time, the debris after punching can fall onto the filter 38 to prevent the debris from entering the second oil storage cavity 31. When the support base plate 7 moves downward, the rack 9 can be driven to pass through the second gear 24, so that the second gear 24 can drive the first gear 23 to rotate at the same time, and when the first gear 23 rotates, the winding wheel 22 can be driven to rotate at the same time, so that the connecting rope 35 can pull the connecting vertical frame 36 and the scraper 32 to the end close to the circulating pump 34, so that the debris accumulated on the filter 38 can be pushed into the storage cavity 29. Then, the hydraulic device 6 can be started to drive the support The base plate 7 moves upward and resets, so that the rack 9 can pass the second gear 24 again, so that the winding wheel 22, the first gear 23 and the second gear 24 can rotate in the opposite direction at the same time, so that the connecting rope 35 can be released. At the same time, the elasticity of the second reset spring 30 will pull the connecting vertical frame 36 to reset, so that the scraper 32 can clean the top surface of the filter 38 when moving or resetting. At the same time, storage cavities 29 are installed on both sides of the second oil storage cavity 31, so that the debris swept from the top of the filter 38 can be received, and the debris diversion and removal work is completed. Subsequently, when the supporting base plate 7 drives the rack 9 to move upward, it can drive the first alignment key 8 to pass the second alignment key 18 again, so that the stamping oil inside the first oil storage cavity 27 can be released again.The punching head 10 is lubricated again, and the punching oil on the punching head 10 can flow and drip onto the chain pin 2, so that the debris attached to the chain pin 2 can be taken away. At the same time, the circulation pump 34 can be started, and the second oil storage chamber 31 and the first oil storage chamber 27 are communicated with each other through the delivery pipe 33, so that the circulation pump 34 can circulate and discharge the punching oil inside the second oil storage chamber 31 to the inside of the first oil storage chamber 27 through the delivery pipe 33, so that the grease storage amount inside the first oil storage chamber 27 can be guaranteed, and the work of recycling the punching oil can be completed. When the device is in use, when it is started by the hydraulic equipment 6, it can drive the first alignment key 8 and the rack 9 to pass through the second alignment key 18 and The second gear 24 drives the sealing rubber plug 28 to be drawn out from the inside of the delivery pipe 20 when the second alignment key 18 approaches one end of the first oil storage cavity 27, so that the lubricating oil inside the first oil storage cavity 27 can be discharged to the outer ring of the punch head 10 through the delivery pipe 20, thereby completing the work of fully lubricating the surface of the punch head 10 and the chain pin 2. In addition, when the second gear 24 rotates, it can drive the reel 22 to pull the connecting rope 35 to drive the scraper 32 to move back and forth on the top of the filter 38, so that the debris accumulated on the filter 38 can be swept into the inside of the storage cavity 29, which can avoid the work of accumulating too much debris on the filter 38, effectively improving the efficiency of the circulating pump 34 in recycling the stamping oil, and completing the work.

[0039] Example 2

[0040] On the basis of Example 1, Figure 8 As shown, the storage cavity 29 also includes a transfer cavity 39, a positioning rod 40 and a handle 41. The handle 41 is fixedly installed on the top of the side end of the transfer cavity 39. The transfer cavity 39 is slidably inserted into the inside of the side end of the storage cavity 29. The positioning rod 40 is symmetrically slidably inserted into the handle 41 and the top end of the storage cavity 29. Circular holes are opened through the top end of the storage cavity 29 close to the handle 41 and the top end of the handle 41, so that the transfer cavity 39 can be restricted when the positioning rod 40 is inserted into the circular hole.

[0041] When implementing this embodiment, the transfer cavity 39 is slidably inserted into the interior of the storage cavity 29 so that debris can fall into the interior of the transfer cavity 39 for unified collection. Subsequently, when the debris inside the transfer cavity 39 accumulates to a certain amount, the positioning rod 40 can be pulled upward so that the positioning rod 40 is moved out of the handle 41 and the interior of the storage cavity 29, and then the handle 41 is pulled outward so that the transfer cavity 39 can be pulled out from the interior of the storage cavity 29, so as to facilitate dumping the debris inside the transfer cavity 39. Subsequently, the transfer cavity 39 is inserted into the interior of the storage cavity 29 again. When the transfer cavity 39 moves to the extreme position inside the storage cavity 29, the circular hole at the top of the handle 41 can be driven to be vertically aligned with the circular hole of the storage cavity 29 near the top of the handle 41. Subsequently, the positioning rod 40 is inserted into the interior of the circular hole so that the transfer cavity 39 can be restricted and installed inside the storage cavity 29 to complete the work.

[0042] 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.
