Description

Technical Field

[0001] This utility model relates to the field of bolt tapping technology, and in particular to a tapping device for high-strength countersunk bolts. Background Technology

[0002] Bolts are a common type of fastener used in daily life. Tapping bolts is a tedious task. Manual tapping is slow and inaccurate, which not only affects the production efficiency of bolts but also has a significant impact on the quality of the bolts.

[0003] A search revealed a bolt tapping device, such as the one disclosed in publication number CN210731261U, which includes a worktable. The worktable is horizontally spaced with a telescopic unit, a fixing unit, and a clamping unit. A power unit is fixedly connected to the telescopic unit, and a tapping disc is connected to the power unit, which powers the tapping disc to rotate. The fixing unit has a through hole for bolts to pass through, and the through hole is coaxial with the tapping disc. The clamping unit has a pressure plate for clamping the bolts, and the clamping unit allows the pressure plate to reciprocate along the axial direction of the through hole. The telescopic unit allows the tapping disc to reciprocate along the axial direction of the through hole.

[0004] The above-mentioned technical solution has certain beneficial effects, but in actual use, simply squeezing the bolt head for fixing can easily cause the bolt to rotate during the tapping process, making it impossible to guarantee that the bolt is completely stable when fixed, thus affecting the tapping accuracy. Therefore, we propose a tapping device for high-strength countersunk bolts. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a tapping device for high-strength countersunk bolts, which can solve the problems existing in the background art.

[0006] The technical solution of this utility model is:

[0007] A tapping device for high-strength countersunk bolts includes a mounting base plate. A support block is fixedly connected to the bottom end of the mounting base plate, and a fixed mounting block is fixedly connected to the middle of the top end of the mounting base plate. A first fixed sleeve block is fixedly connected to one end of the top of the mounting base plate. A first electric telescopic rod is fixedly connected inside the first fixed sleeve block.

[0010] In a further technical solution, the outer surfaces of the movable bit rod and the fixed limiting rod slide and fit against the inner surface of the fixed limiting through hole.

[0011] In a further technical solution, a lifting handle is fixedly connected to the top of the movable insert.

[0012] In a further technical solution, the connecting limiting mechanism includes a connecting sleeve block, a movable insert rod is movably connected inside the connecting sleeve block, a force-bearing mounting ring is fixedly sleeved on the outer surface of the movable insert rod, a second spring is fixedly connected between one side of the force-bearing mounting ring and one inner end of the connecting sleeve block, a connecting pull arm is fixedly connected to one end of the movable insert rod, a fixing groove is provided on the top of the connecting pull arm, and the inner side of the fixing groove slides against the outer surface of the connecting sleeve.

Detailed Implementation

[0023] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] Example:

[0025] like Figures 1-4 As shown, a high-strength countersunk bolt tapping device includes a mounting base plate 1. A support block 2 is fixedly connected to the bottom end of the mounting base plate 1. A fixed mounting block 3 is fixedly connected to the middle of the top end of the mounting base plate 1. A first fixed sleeve block 4 is fixedly connected to one end of the top of the mounting base plate 1. A first electric telescopic rod 5 is fixedly connected inside the first fixed sleeve block 4. A connecting mounting plate 6 is fixedly connected to the output end of the first electric telescopic rod 5. An output motor 7 is fixedly connected to one side of the connecting mounting plate 6. A tapping disc 8 is fixedly connected to the output end of the output motor 7. A fixed through hole 9 is opened in the middle of the fixed mounting block 3. Fixed guide rails 10 are symmetrically arranged at the other end of the top of the mounting base plate 1. A second fixed sleeve block 11 is fixedly connected to the top of the fixed guide rail 10. A second electric telescopic rod 12 is fixedly connected inside the second fixed sleeve block 11. A movable mounting plate 13 is fixedly connected to the output end of the second electric telescopic rod 12. A connecting clamping and positioning mechanism 14 is movably inserted into the inner side of the movable mounting plate 13.

[0026] The working principle of the above technical solution is as follows:

[0027] During use, the countersunk bolt can be inserted into the inner side of the fixing through hole 9, so that the head of the countersunk bolt is on the side close to the second fixing sleeve block 11. Then, the second electric telescopic rod 12 can push the movable mounting plate 13, which drives the connecting clamping and positioning mechanism 14 to move, so that one end of the connecting clamping and positioning mechanism 14 can squeeze and fix the end of the countersunk bolt. At the same time, the internal components of the connecting clamping and positioning mechanism 14 can be inserted into the groove of the head of the countersunk bolt, thereby stably restricting and fixing the countersunk bolt, and thus enabling the countersunk bolt to be stably tapped. It is convenient and quick to use.

[0028] In another embodiment, such as Figure 1 As shown, the connecting clamping and positioning mechanism 14 is symmetrically provided with a fixed connecting plate 15 on the side near the second fixed sleeve block 11, and the movable mounting plate 13 is symmetrically provided with a connecting mounting bracket 16 on the side near the second fixed sleeve block 11. A connecting limiting mechanism 17 is fixedly connected to the surface of the connecting mounting bracket 16.

[0029] The fixed connecting plate 15 can be inserted into the inner side of the connecting mounting bracket 16, and the position of the fixed connecting plate 15 can be restricted and fixed under the action of the connecting limiting mechanism 17, thereby restricting and fixing the connecting clamping and positioning mechanism 14, so that the connecting clamping and positioning mechanism 14 can be stably used inside the movable mounting plate 13, which is convenient to operate.

[0030] In another embodiment, such as Figure 2 and 3 As shown, the connecting clamping and positioning mechanism 14 includes a movable insert block 18. A fixed compression anti-slip disc 19 is fixedly connected to the side of the movable insert block 18 away from the second fixed sleeve block 11. A connecting sleeve 20 is fixedly connected to the side of the movable insert block 18 close to the second fixed sleeve block 11. Fixed limiting through holes 21 are opened inside the connecting sleeve 20, the movable insert block 18 and the fixed compression anti-slip disc 19. A movable bit rod 22 is movably connected inside the connecting sleeve 20. Fixed limiting rods 23 are symmetrically arranged on the outer surface of the movable bit rod 22. A force-bearing collar 24 is fixedly sleeved on the outer surface of the movable bit rod 22 and the fixed limiting rod 23. A first spring 25 is fixedly connected between one side of the force-bearing collar 24 and one end of the inner surface of the connecting sleeve 20.

[0031] The anti-slip disc 19, which is designed to facilitate the fixing of the countersunk bolt head, can press the head of the countersunk bolt. At the same time, the end of the movable bit rod 22 will first contact the end of the countersunk bolt. The end of the movable bit rod 22 can be inserted into the groove at the end of the countersunk bolt. During the contact between the fixed anti-slip disc 19 and the countersunk bolt, the movable bit rod 22 drives the fixed limit rod 23 and the force-bearing collar 24 to move, which compresses the first spring 25, thereby quickly restricting and fixing the countersunk bolt. The operation is convenient.

[0032] In another embodiment, such as Figure 3 As shown, the outer surfaces of the movable bit rod 22 and the fixed limiting rod 23 slide against each other with the inner surface of the fixed limiting through hole 21.

[0033] This allows the movable bit rod 22 and the fixed limiting rod 23 to move stably inside the fixed limiting through hole 21, making operation convenient.

[0034] In another embodiment, such as Figure 2 As shown, a lifting handle 26 is fixedly connected to the top of the movable insert 18.

[0035] The handle 26 is easy to pull, which allows the movable insert 18 to move quickly, making it easy to operate.

[0036] In another embodiment, such as Figure 4 As shown, the connecting limiting mechanism 17 includes a connecting sleeve block 27. A movable insert rod 28 is movably connected inside the connecting sleeve block 27. A force-bearing mounting ring 29 is fixedly sleeved on the outer surface of the movable insert rod 28. A second spring 30 is fixedly connected between one side of the force-bearing mounting ring 29 and one end of the inner side of the connecting sleeve block 27. A connecting pull arm 31 is fixedly connected to one end of the movable insert rod 28. A fixing groove 32 is provided on the top of the connecting pull arm 31. The inner side of the fixing groove 32 slides against the outer surface of the connecting sleeve 20.

[0037] This facilitates the movement of the connecting arm 31, which in turn moves the movable insert rod 28 and the force-bearing mounting ring 29, compressing the second spring 30. This allows the end of the movable insert rod 28 to retract towards the inside of the connecting sleeve block 27, enabling quick adjustment and convenient use.

[0038] In another embodiment, such as Figure 4 As shown, the other end of the movable insertion rod 28 is provided with a pressure-bearing inclined surface 33.

[0039] This facilitates the stable movement of the connecting arm 31 on the outer surface of the connecting sleeve 20, making operation convenient.

[0040] The working principle of this utility model is as follows: During use, the countersunk bolt is inserted into the inner side of the fixing through hole 9, so that the head of the countersunk bolt is positioned on the side of the fixing mounting block 3 near the second fixing sleeve block 11. Then, the second electric telescopic rod 12 can push the movable mounting plate 13, which can drive the connecting clamping and positioning mechanism 14, the fixing connecting plate 15, the connecting mounting bracket 16, and the connecting limiting mechanism 17 to move as a whole. During this process, the end of the movable bit rod 22 can be inserted into the groove of the countersunk bolt head. At this time, the connecting clamping and positioning mechanism 14, the fixing connecting plate 15, the connecting mounting bracket 16, and the connecting limiting mechanism 17 can move as a whole. The connecting limiting mechanism 17 moves continuously until the fixed compression anti-slip disc 19 and the head of the countersunk bolt are pressed against each other. The movable bit rod 22 can move inside the connecting sleeve 20, driving the fixed limiting rod 23 and the force-bearing collar 24 to move, compressing the first spring 25. This allows for self-adjustment, ensuring stable clamping and positioning of the countersunk bolt, enabling stable tapping. When the connecting clamping and positioning mechanism 14 needs to be replaced according to the groove on the head of the countersunk bolt, the connecting pull arm 31 is first moved, carrying... The movable insert rod 28 and the force-bearing mounting ring 29 move, compressing the second spring 30. This allows the end of the movable insert rod 28 to retract inwards towards the connecting sleeve 27, enabling it to be pulled out from the inside of the fixed connecting plate 15. The lifting handle 26 is then pulled up, allowing the entire connecting clamping and positioning mechanism 14 and the fixed connecting plate 15 to be disassembled and replaced. After replacement, the entire connecting clamping and positioning mechanism 14 is inserted into the inside of the movable mounting plate 13, while the fixed connecting plate 15 is inserted into the inside of the connecting mounting bracket 16. The bottom edge of the fixed connecting plate 15 can withstand pressure. The inclined plane 33 causes compression, allowing the end of the movable insert 28 to move inward toward the connecting sleeve 27, which in turn moves the force-bearing mounting ring 29 and compresses the second spring 30. When the fixed connecting plate 15 is fully inserted into the inner side of the connecting mounting bracket 16, the force-bearing mounting ring 29, under the action of the second spring 30, drives the movable insert 28 to reset, so that the end of the movable insert 28 can be stably inserted into the interior of the fixed connecting plate 15, thereby restricting and fixing the position of the fixed connecting plate 15 and the connecting clamping positioning mechanism 14. The overall structure is simple and the operation is convenient and quick.

[0041] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
