Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to the attached Figure 1-14 , and the present application provides the following technical solutions.

[0037] Embodiment 1: A tapping machine with a fast feeding component, including a terminal tapping loading tray 1. Chip removal cavity grooves 2 are provided on one side of the terminal tapping loading tray 1. Terminal sliding grooves 3 are provided on both sides at the upper end inside the chip removal cavity grooves 2. A U-shaped screw-connected terminal 4 is horizontally arranged inside the chip removal cavity grooves 2, and the lower ends on both sides of the U-shaped screw-connected terminal 4 are respectively inserted into the two U-shaped screw-connected terminals 4. Through the telescopic push rod, the U-shaped screw-connected terminal 4 can be quickly pushed into the terminal sliding groove 3 through the chute provided on the terminal tapping loading tray 1 and be in the tapping position, waiting for the processing operation.

[0038] A positioning component is provided to position the position of the U-shaped screw-connected terminal 4. The positioning component is arranged inside the chip removal cavity grooves 2 through a sliding support component. The sliding support component includes a mounting support 5 and two sliding support tubes 30. A sliding groove is provided at the upper end of the mounting support 5. The lower end of the positioning movable box 6 is vertically inserted into the sliding groove. Rod grooves are provided at the upper ends on both sides inside the sliding groove of the mounting support 5. The two sliding support tubes 30 are respectively horizontally arranged in the two rod grooves. Sliding sleeves 31 are horizontally arranged on both sides of the positioning movable box 6, and the two sliding sleeves 31 respectively slide and sleeved on the two sliding support tubes 30. The positioning movable box 6 can perform horizontal micro-sliding adjustment inside the mounting support 5 to adapt to the processing position.

[0039] The positioning component includes a positioning movable box 6, a pre-positioning block 13, and an adjustment docking tube 17. The positioning movable box 6 is slidably arranged above the mounting support 5. The pre-positioning block 13 is vertically and movably inserted into the upper end of the positioning movable box 6. The upper end of the pre-positioning block 13 is inserted into the lower end of the U-shaped screw-connected terminal 4. The adjustment docking tube 17 is vertically and movably inserted into the upper end of the pre-positioning block 13. A first-stage telescopic groove 7 is provided inside the positioning movable box 6. A piston disk 8 is horizontally arranged at the upper end inside the first-stage telescopic groove 7. A convex block is provided at the center of the lower end of the piston disk 8. A number of adaptation guide grooves 9 are provided at the lower end of the convex block. A number of holding guide rods 10 are vertically and symmetrically arranged at the center of the lower end inside the first-stage telescopic groove 7. The upper ends of the number of holding guide rods 10 are respectively movably inserted into the number of adaptation guide grooves 9. A first spring 11 is provided at the center of the lower end of the piston disk 8, and the first spring 11 is sleeved on the convex block. The piston disk 8 can move up and down inside the first-stage telescopic groove 7, and the first spring 11 plays a role in supporting the position of the piston disk 8 in its natural state;

[0040] The pre-positioning block 13 is vertically arranged at the center of the upper end of the piston disk 8. The upper end of the pre-positioning block 13 movably penetrates through the upper end of the positioning movable box 6. The two side surfaces of the upper end of the pre-positioning block 13 penetrating through the positioning movable box 6 are inclined surfaces. The upper end of the pre-positioning block 13 is inserted into the U-shaped groove of the U-shaped screw terminal 4. The width of the pre-positioning block 13 is equal to the width of the U-shaped groove of the U-shaped screw terminal 4. On both sides of the pre-positioning block 13 outside the positioning movable box 6, there are abutting blocks. When the pre-positioning block 13 rises to the maximum extent, the two abutting blocks respectively abut against the lower ends of the two side walls of the U-shaped screw terminal 4. On the upper end of the piston disk 8, a number of second springs 12 are symmetrically arranged. The upper ends of the number of second springs 12 respectively abut against the upper end surface in the first-stage telescopic groove 7. In the natural state, the combined resilience of the number of second springs 12 can offset the resilience of the first spring 11. At this time, the upper end of the pre-positioning block 13 with an inclined surface is placed in the U-shaped groove of the U-shaped screw terminal 4. When the U-shaped screw terminal 4 is pushed to the position of the pre-positioning block 13 through the telescopic rod, at this time, the height of the lower end surface of the U-shaped screw terminal 4 is equal to the horizontal height of the middle part of the inclined surface of the pre-positioning block 13. When the U-shaped screw terminal 4 is pushed to the position of the pre-positioning block 13 and continues to move, the pre-positioning block 13 will carry out a pressing-down activity under the action of the inclined surface, and then under the elastic support of the first spring 11, the pre-positioning block 13 rebounds and is inserted into the U-shaped groove of the U-shaped screw terminal 4 to carry out the basic positioning of the U-shaped screw terminal 4;

[0041] When the pre-positioning block 13 rises, under the action of the two inclined surfaces, the pre-positioning block 13 adjusts the position of the U-shaped screw terminal 4. Then, the two vertical surfaces of the pre-positioning block 13 contact the vertical side surfaces in the U-shaped groove of the U-shaped screw terminal 4, and the U-shaped screw terminal 4 is positioned and held to carry out the advanced positioning and stable holding of the U-shaped screw terminal 4.

[0042] A secondary expansion slot 14 is provided in the center of the pre-positioning block 13. A reciprocating piston 15 is horizontally provided at the upper end inside the secondary expansion slot 14. A support sleeve 16 is vertically provided at the center of the upper end of the reciprocating piston 15. The support sleeve 16 is movably penetrated through the upper end of the pre-positioning block 13. A third spring 18 is provided at the upper end of the reciprocating piston 15. An adjustment docking pipe 17 is rotatably provided inside the support sleeve 16, and the upper end of the adjustment docking pipe 17 penetrates through the tapping hole of the U-shaped screw connection terminal 4. An access slot is provided on one side of the mounting seat 5. The positioning movable box 6 is located on one side of the access slot and communicates with the primary expansion slot 7 to be provided with a source gas joint 23. The lower end inside the secondary expansion slot 14 penetrates through the convex block and communicates with the primary expansion slot 7. The center of the adjustment docking pipe 17 penetrates through the reciprocating piston 15 and communicates with the secondary expansion slot 14. And the diameter of the adjustment docking pipe 17 is smaller than the diameter of the secondary expansion slot 14 communicating with the primary expansion slot 7. When the source gas joint 23 feeds high-pressure gas, a part of the high-pressure gas is discharged from the adjustment docking pipe 17. When the flow rate of the high-pressure gas fed into the primary expansion slot 7 is greater than the discharge flow rate of the adjustment docking pipe 17, the high-pressure gas will first push the reciprocating piston 15, the support sleeve 16 and the adjustment docking pipe 17 to lift. Then, as the air pressure continues to increase, the piston disc 8 will drive the pre-positioning block 13 to lift, so as to correct and position the U-shaped screw connection terminal 4;

[0043] On the contrary, when the high-pressure gas is cut off, the adjustment docking pipe 17 and the reciprocating piston 15 retract into the pre-positioning block 13 under the elastic action of the third spring 18, without affecting the preliminary positioning between the U-shaped screw connection terminal 4 and the pre-positioning block 13.

[0044] A tapping tool 19. A tapping hole is provided on one side of the U-shaped screw connection terminal 4. The tapping tool 19 is located above the tapping hole, and the upper end of the adjustment docking pipe 17 is inserted into the lower end of the tapping tool 19. A tapered fine-tuning groove 20 is provided at the center of the lower end of the tapping tool 19. A heat dissipation central groove 21 is provided at the center of the tapping tool 19. A diversion groove is provided at the upper end inside the heat dissipation central groove 21. A plurality of inclined blowing holes 22 are obliquely and downwardly penetrated through the diversion groove. The upper end of the adjustment docking pipe 17 is inserted into the tapered fine-tuning groove 20. A plurality of side blowing holes 24 are provided in the chip removal cavity groove 2 above the terminal slideway 3 and close to one side of the tapping tool 19. When the U-shaped screw connection terminal 4 is preliminarily positioned and the source gas joint 23 feeds high-pressure air flow to control the adjustment docking pipe 17 and the pre-positioning block 13 to lift, the upper end of the adjustment docking pipe 17 penetrates through the tapping hole of the U-shaped screw connection terminal 4. At this time, when the tapping tool 19 vertically descends, the adjustment docking pipe 17 is inserted into the tapered fine-tuning groove 20 of the tapping tool 19 first. If the central axes of the adjustment docking pipe 17 and the tapping tool 19 are offset, the tapping tool 19 can push the adjustment docking pipe 17 to slide left and right through the tapered fine-tuning groove 20. Furthermore, after the adjustment docking pipe 17 acts on the pre-positioning block 13 and the piston disc 8, the positioning movable box 6 is controlled to slide and adjust on the mounting seat 5, so that the tapping tool 19 is aligned with the tapping hole of the U-shaped screw connection terminal 4;

[0045] After alignment, the tapping tool 19 continues to descend. The tapping tool 19 pushes the adjustment butt joint pipe 17 and the reciprocating piston 15 to overcome the support of the high-pressure gas and continues to descend to tap the U-shaped screw terminal 4. During tapping, the adjustment butt joint pipe 17 continuously blows high-pressure air flow. The high-pressure air flow enters the heat dissipation central groove 21 and the shunt groove of the tapping tool 19, and then blows downward from a number of inclined blowing holes 22. Combined with the side blowing holes 24, the debris generated by tapping the U-shaped screw terminal 4 is blown downward into the chip discharge cavity groove 2, and then falls out for discharge;

[0046] When the pre-positioning block 13 rises to the maximum extent, the abutting block can push the upper end of the U-shaped screw terminal 4 to abut against the upper end inside the terminal slideway 3, maintaining a stable posture during the tapping process, serving the purpose of strengthening stability and positioning, and enhancing the tapping quality.

[0047] Embodiment 2: On the basis of Embodiment 1, the sliding between the mounting support 5 and the positioning movable box 6 can be lubricated. One side of the first-stage telescopic groove 7 is provided with a gas pushing joint 25. A gas pushing piston groove 26 is opened in the gas pushing joint 25. A piston rod 27 is vertically provided on one side of the piston disk 8 located in the gas pushing joint 25. The lower end of the piston rod 27 is movably inserted into the gas pushing piston groove 26 through a sealing sleeve ring. An oil storage groove 28 is opened on one side inside the mounting support 5. One side of the gas pushing piston groove 26 and the upper end side of the oil storage groove 28 are connected and inserted with a gas pushing hose 29. One side of the sliding support pipe 30 is communicated with the lower end side of the oil storage groove 28, and a lifting oil groove 33 is opened. A one-way valve 34 is provided on one side of the lifting oil groove 33 close to the oil storage groove 28. A number of oil replenishing holes 32 are penetrated and opened at the upper end of the sliding support pipe 30. The sliding sleeve 31 sleeved on one side of the sliding support pipe 30 covers a number of oil replenishing holes 32. When the source gas joint 23 stops gas transmission, a number of second springs 12 need to push the piston disk 8 downward to the balanced support position of the first spring 11. At this time, the piston disk 8 drives the piston rod 27 to slide downward in the gas pushing piston groove 26. At this time, the piston rod 27 pushes the air flow in the gas pushing piston groove 26 into the oil storage groove 28. Then, under the action of the top air pressure of the lubricating oil in the oil storage groove 28, the lubricating oil is respectively pushed by the two one-way valves 34 into the lifting oil groove 33. Thus, under the action of the frequent reciprocating movement of the gas pushing piston groove 26, the lubricating oil in the oil storage groove 28 is added to the sliding support pipe 30 in small amounts each time, and then under the action of the oil replenishing holes 32, it overflows and coats the position where the sliding sleeve 31 sleeves the sliding support pipe 30, continuously lubricating the sliding of the positioning movable box 6 and maintaining the smooth effect when the adjustment butt joint pipe 17 toggles the positioning movable box 6.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
