[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0026] like Figures 1-6 As shown, a precision automatic tapping machine for terminal blocks according to an embodiment of the present disclosure is illustrated. It includes a worktable 1, a movable plate 2 movably connected to the left side of the top of the worktable 1, and a connecting plate 3 fixedly connected to the right side of the top of the worktable 1. A first clamping block 4 and a second clamping block 5 are movably connected to the opposite surfaces of the movable plate 2 and the connecting plate 3, respectively. A movable shaft 6 located inside the movable plate 2 is fixedly connected to the left side of the first clamping block 4. The outer surface of the movable shaft 6 is movably connected to the interior of the movable plate 2. A protective cover 7 is fixedly connected to the front of the left side of the bottom of the worktable 1. A first motor 8 is fixedly installed inside the protective cover 7. A rotating shaft 9 is fixedly sleeved at the other end of the output shaft of the first motor 8. The top end of the rotating shaft 9 passes through the protective cover 7 and extends to the outside of the top of the protective cover 7, with a long rod 10 fixedly sleeved on its outer surface. A round shaft 11 is movably connected inside the long rod 10. A movable block 12 located inside the worktable 1 is fixedly connected to the top end of the round shaft 11. The top end of the movable block 12 is fixedly connected to the bottom end of the movable plate 2.
[0027] The protective cover 7 is designed to block dust from the outer surface of the first motor 8, while the hollow design of the long rod 10 limits the subsequent movement of the round shaft 11. The design of the movable block 12 allows it to drive the movable plate 2 to move together.
[0028] In some examples, table legs 13 are fixedly connected to the four corners of the bottom of the workbench 1. There are four table legs 13, and the four table legs 13 are the same size.
[0029] The design of the four table legs 13 provides excellent support for the workbench 1 as a whole.
[0030] In some examples, a protective cover 14 is fixedly connected to the right side of the front of the workbench 1, and a second motor 15 is fixedly installed inside the protective cover 14.
[0031] Due to the design of the protective cover 14, the second motor 15 is well protected.
[0032] In some examples, the other end of the output shaft of the second motor 15 is fixedly sleeved with a lead screw 16, the other end of which passes through the protective cover 14 and extends into the interior of the worktable 1 and is movably connected to the interior of the worktable 1.
[0033] Since the outer surface of the lead screw 16 is smooth, as are the interior of the protective cover 14 and the interior of the worktable 1, the friction between the outer surface of the lead screw 16 and the interior of the protective cover 14 and the interior of the worktable 1 can be reduced.
[0034] In some examples, a slider 17 is threaded onto the rear of the outer surface of the lead screw 16. The outer surface of the slider 17 is movably connected to the interior of the worktable 1. A toothed plate 18 is fixedly connected to the top of the slider 17, and the bottom end of the toothed plate 18 is movably connected to the top of the worktable 1.
[0035] Due to the design of slider 17, it has a limiting effect on the subsequent movement of toothed plate 18.
[0036] In some examples, the right side of the second clamping block 5 is fixedly connected to a motion shaft 27 located inside the connecting plate 3, and the outer surface of the motion shaft 27 is movably connected to the interior of the connecting plate 3.
[0037] The design of the motion shaft 27 prevents the second clamping block 5 from falling off.
[0038] In some examples, a short shaft 19 is fixedly connected to the right side of the motion shaft 27. The right end of the short shaft 19 passes through the connecting plate 3 and extends to the outside of the right side of the connecting plate 3. The outer surface of the short shaft 19 is movably connected to the inside of the connecting plate 3. A gear 20 is fixedly sleeved on the right side of the outer surface of the short shaft 19. The outer surface of the gear 20 meshes with the outer surface of the gear plate 18.
[0039] Since the toothed plate 18 and the gear 20 are meshed, the toothed plate 18 will move when the gear 20 rotates.
[0040] In some examples, a connecting frame 21 is movably connected to the rear of the top of the workbench 1. A first pneumatic cylinder 22 is fixedly installed at the top of the connecting frame 21. The bottom end of the first pneumatic cylinder 22 passes through the connecting frame 21 and extends to the outside of the top of the inner surface of the connecting frame 21 and is fixedly connected to a rectangular cover 23.
[0041] Due to the design of the No. 1 pneumatic cylinder 22, the rectangular cover 23 can move downward as a whole.
[0042] In some examples, a third motor 24 is fixedly installed inside the rectangular cover 23, and a rotating shaft 25 is fixedly sleeved at the other end of the output shaft of the third motor 24. The bottom end of the rotating shaft 25 passes through the rectangular cover 23 and extends to the outside of the bottom end of the rectangular cover 23 and is fixedly connected to a tapping drill bit 26.
[0043] Because the third motor 24 has the function of forward and reverse rotation, it enables the rotating shaft 25 and the tapping drill bit 26 to better perform tapping operations on the terminals.
[0044] In some examples, a second pneumatic cylinder 29 is fixedly installed on the rear left side of the workbench 1. The right end of the second pneumatic cylinder 29 passes through the workbench 1 and extends into the interior of the workbench 1 and is movably connected to the interior of the workbench 1. A movable block 28 is fixedly connected to the right end of the second pneumatic cylinder 29. The top end of the movable block 28 is fixedly connected to the bottom end of the connecting frame 21. The outer surface of the movable block 28 is movably connected to the interior of the workbench 1.
[0045] Due to the design of the movable block 28, it can guide the connecting frame 21.
[0046] Working principle and usage process of this utility model: First, the operator places the right end of the terminal block into the inside of the second clamping block 5. Then, the operator starts the first motor 8, which causes the rotating shaft 9 and the long rod 10 to rotate. This causes the inner surface of the long rod 10 to press and push the outer surface of the round shaft 11, which in turn causes the round shaft 11 to drive the movable block 12 and the movable plate 2 to move to the right. This allows the inside of the first clamping block 4 to press and fix the left end of the terminal block of different lengths. Then, the operator starts the third motor 24 and the first pneumatic cylinder 22. The operation of the third motor 24 causes the rotating shaft 25 and the tapping drill bit 26 to rotate, while the operation of the first pneumatic cylinder 22 causes the rectangular cover 23 to move downward, allowing the tapping drill bit 26 to tap the terminal block.
[0047] Finally, the operator starts the second motor 15 and the second pneumatic cylinder 29, which causes the lead screw 16 to rotate, thereby causing the slider 17 to drive the toothed plate 18 to move forward. This causes the outer surface of the toothed plate 18 to mesh with the outer surface of the gear 20, which in turn causes the gear 20 to drive the short shaft 19, the motion shaft 27, the second clamping block 5, and the first clamping block 4 to rotate. This allows the terminal between the first clamping block 4 and the second clamping block 5 to rotate, enabling the tapping drill bit 26 to tap the other surfaces of the terminal. The operation of the second pneumatic cylinder 29 causes the connecting frame 21 to move to the left, allowing the tapping drill bit 26 to tap various positions on the top of the terminal.
[0048] 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.
