Description

Technical Field

[0001] The invention relates to the technical field of automobile manufacturing, in particular to a quick-adjusting tapping device for automobile parts. Background Art

[0002] As the automotive manufacturing industry develops towards intelligence and efficiency, the production precision and processing efficiency of auto parts have become core indicators for measuring a company's competitiveness. Tapping, as a key process in auto parts manufacturing, has a direct impact on the assembly reliability of parts and the performance of the vehicle. As the automotive industry's demand for diversified and customized parts grows, tapping equipment must meet the dual requirements of high-precision processing and rapid switching of production tasks.

[0003] At present, traditional tapping equipment for automotive parts has significant technical bottlenecks in practical applications. On the one hand, during tapping operations, if there are internal defects in the workpiece material, chip blockage, or bottom hole size deviation, the tap is very likely to get stuck. Due to the lack of intelligent torque monitoring and emergency response mechanisms in existing equipment, the power system continues to transmit torque, causing the tap to be subjected to overload stress and frequently break. This not only significantly increases the cost of tool wear, but also seriously affects production continuity due to downtime and maintenance. On the other hand, traditional equipment often uses universal fixtures for workpiece fixation, which is difficult to quickly adapt to accessories of different specifications, and the fixed position is prone to blocking the hole to be processed, requiring repeated adjustment of the clamping position, which not only reduces processing efficiency but may also affect the tapping accuracy due to positioning deviation. In addition, the manual clamping process relies on the operator's experience, and there are problems such as uneven fixing force and long time consumption, which cannot meet the large-scale and high-precision production needs of automotive parts.

[0004] Therefore, it is urgent to develop an automotive parts tapping equipment that integrates intelligent anti-breakage protection and fast and precise clamping. The equipment needs to realize automatic shaft breakage protection when the tap is stuck, and at the same time have flexible and efficient workpiece fixing and rapid adjustment functions to improve the reliability, efficiency and automation level of automotive parts tapping processing.

[0005] After searching, it was found that the prior art publication number is CN116275314A, which discloses a tapping device, including a support seat, a first support plate is installed on the left side surface of the support seat, and a second support plate is installed on the left side surface of the support seat above the first support plate, and a first adjusting mechanism is provided on the upper surface of the support seat, a second adjusting mechanism is provided on the upper end of the first adjusting mechanism, and a mounting mechanism is provided on the upper end of the second adjusting mechanism; the invention can quickly adjust the position of the workpiece in the left and right directions through the first adjusting mechanism, and the second adjusting mechanism can quickly adjust the position of the workpiece in the front and back directions, and the third motor in the mounting mechanism drives the synchronous belt to rotate so that the two clamping plates are close until the workpiece is fixed, and the two clamping plates can fix the workpiece more firmly, clamp and fix it on the side of the workpiece, and will not block the hole that needs to be tapped, and the fixing process is very simple and convenient because it is driven by the third motor.

[0006] Therefore, based on the above search and combined with the existing, in the above device, the second adjustment mechanism supports the rapid positioning of the workpiece forward and backward, and the third motor in the installation mechanism drives the synchronous belt to make the two clamping plates smoothly approach and fix the workpiece. The side clamping method ensures firm fixation without blocking the tapping hole position. However, it is unable to stop the rotation for protection when the tap is overloaded during tapping, which has limitations. For this reason, we propose a quick-adjust tapping device for automotive parts. Summary of the Invention

[0013] As a further feature of this solution, the trigger mechanism includes a second connecting plate, which is fixedly connected to the main shaft, and the end of the second connecting plate away from the main shaft is fixedly connected to the first elastic telescopic rod, and the end of the first elastic telescopic rod away from the third elastic telescopic rod is fixedly connected to the second connecting circular plate, and a plurality of mating holes are opened inside the second connecting circular plate.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When in use, place the auto part on the fixed frame, start the second servo motor to drive the threaded rod to rotate, and drive the movable slide to move. During this process, the abutment wheel slides along the abutment inclined plate, causing the two abutment blocks to move closer to each other, thus achieving a stable clamping of the auto part. Through automatic positioning and clamping, there is no need for manual repeated adjustment, which significantly improves the clamping efficiency. The part is fixed in a symmetrical contraction manner, and the force is evenly distributed, which can effectively avoid the processing deviation of the part due to unstable clamping.

[0022] 2. The first servo motor sequentially drives the coordinated rotation of each component, ultimately driving the tap to process the automotive part. If the tap becomes blocked by chips or excessive resistance, an intelligent protection mechanism is triggered: the rotating wheel pulls the second pull cord, causing the second elastic telescopic rod to retract. This in turn pushes the moving block, which in turn drives the abutment tube, severing the transmission connection and quickly stopping the tap. This ensures stable and efficient tapping transmission and can quickly respond to abnormal operating conditions. By automatically disconnecting the transmission path, the tap is prevented from breaking due to overload, effectively protecting tool life, reducing downtime and maintenance costs, and improving equipment safety and processing continuity.

[0044] See also Figure 6 、 Figure 7 、 Figure 9 、 Figure 11As shown, a first connecting circular plate 18 is fixedly connected between the third elastic telescopic rod 17 and the main shaft 6, and a connecting circular plate 18 is rotatably connected to the outer wall of the first connecting circular plate 18. The connecting circular ring 19 is connected to the first connecting circular plate 18. Specifically, a cavity is opened inside the connecting circular ring 19, and a plurality of air holes are opened on the inner wall of the connecting circular ring 19, each of which is connected to the cavity. (For details, please refer to Figure 11 ), the outer wall of the first connecting circular plate 18 is connected to the first rubber corrugated sleeve 20, and the inside of the first rubber corrugated sleeve 20 is fixedly connected to the third spring. The first rubber corrugated sleeve 20 is made of rubber. The first rubber corrugated sleeve 20 is located inside the third elastic telescopic rod 17, and the left end of the inner wall of the third elastic telescopic rod 17 is fixedly connected to the abutting circular rod 21. The end of the fixed circular plate 31 close to the first elastic telescopic rod 22 is fixedly connected to a plurality of second rubber corrugated sleeves 26.

[0045] Specifically, the first servo motor 7 is started to drive the third elastic telescopic rod 17 to rotate through the main shaft 6 and the first connecting circular plate 18, the third elastic telescopic rod 17 drives the second connecting plate 51 and the first elastic telescopic rod 22 to rotate, the first elastic telescopic rod 22 drives the matching hole 24 and the sliding rectangular rod 28 to rotate, the sliding rectangular rod 28 drives the matching circular block 30 to rotate, the matching circular block 30 drives the third connecting circular plate 34 to rotate through the insert block 32 and the through-hole 33, the third connecting circular plate 34 drives the connecting shaft 35 and the rotating wheel 48 to rotate, the rotating wheel 48 drives the second elastic telescopic rod 49 to rotate through multiple second pull ropes 46, the second elastic telescopic rod 49 drives the connecting ring 47 and the tap 52 to rotate, when the second triangular block 44 moves to tap the inner wall of the tooling hole of the automotive accessory, because the tap 52 has been used for too long, it will be worn and not sharp. Tapping at the same speed will cause the third elastic telescopic rod 17 to contract. When the abutting rod 21 abuts against the outer wall of the first rubber bellows 20, the first rubber bellows 20 contracts, and the gas inside the first rubber bellows 20 enters the inside of the connecting ring 19 through the first connecting circular plate 18, and then enters the inside of all the second rubber bellows 26 through the connecting ring 19. The second rubber bellows 26 drives the connecting ring 27 to move, and the connecting ring 27 pulls all the first pull ropes 36, and the first pull ropes 36 pull the abutting tube 39. When the abutting tube 39 is separated from the abutment of the outer walls of all the first triangular blocks 43, the moving box 38 resets and drives the second triangular block 44 to break away from the abutment with the outer wall of the matching circular block 30. At this time, the moving box 38 drives the second triangular block 44 to move a very short distance. At this time, the matching circular block 30 drives all the plug-in blocks 32 to break away from the inside of the through-opening 33, and the rotation of the second triangular block 44 can be stopped immediately to avoid the second triangular block 44 from breaking.

[0046] At this time, the main shaft 6 and the first servo motor 7 continue to be driven to move, and the third elastic telescopic rod 17 continues to be squeezed. After the third elastic telescopic rod 17 is fully retracted, the first elastic telescopic rod 22 is retracted, and all the push rods 23 will pass through the inside of the matching hole 24 to abut the outer wall of the matching round block 30. At this time, when the matching round block 30 moves, it will abut against the outer wall of the second triangular block 44. The second triangular block 44 is abutted and slides toward the inside of the moving box 38 and shrinks. When the matching round block 30 is disengaged from the outer wall of the second triangular block 44, the main shaft 6 and the first servo motor 7 are driven to reset, and the fifth spring 29 drives the matching round block 30 to reset and all the second triangular blocks 44 outer wall abuts, all the plug blocks 32 will be re-engaged with the corresponding through-openings 33. If the engagement fails, it is only necessary to drive the through-opening 33 to adjust the angle. Then the third elastic telescopic rod 17 loses compression, the abutting round rod 21 is separated from the abutment with the outer wall of the first rubber corrugated sleeve 20, the first rubber corrugated sleeve 20 will suck all the second rubber corrugated sleeves 26, and the second rubber corrugated sleeve 26 will release the tension on the first pull rope 36. When all the rotating wheels 48 are reset, the abutting tube 39 will be reset through the connecting arm 45 and the moving block 42 to re-drive the abutting tube 39 to reset. The tap 52 rotates in the opposite direction, and the tap 52 can be taken out and replaced.

[0047] The working principle of the present invention is as follows: when in use, the automobile accessory is placed on the upper end of the fixing frame 50, the second servo motor 10 is started, the second servo motor 10 drives the threaded rod 41 to rotate, and the threaded rod 41 drives the movable slide 8 to move. When the abutment wheel 11 moves along the outer wall of the abutment inclined plate 15 toward the outer wall of the first connecting plate 16, the two abutment wheels 11 will drive the two abutment blocks 14 to move closer and contract through the connecting rod 12, and the abutment blocks 14 fix the automobile accessory. At this time, the movable slide 8 can be driven to move back and forth, and the first servo motor 7 is started to drive the third abutment block 14 through the main shaft 6 and the first connecting circular plate 18. The elastic telescopic rod 17 rotates, and the third elastic telescopic rod 17 drives the second connecting plate 51 and the first elastic telescopic rod 22 to rotate. The first elastic telescopic rod 22 drives the matching hole 24 and the sliding rectangular rod 28 to rotate. The sliding rectangular rod 28 drives the matching circular block 30 to rotate. The matching circular block 30 drives the third connecting circular plate 34 to rotate through the insert block 32 and the through hole 33. The third connecting circular plate 34 drives the connecting shaft 35 and the rotating wheel 48 to rotate. The rotating wheel 48 drives the second elastic telescopic rod 49 to rotate through the multiple second pull ropes 46. The second elastic telescopic rod 49 drives the connecting ring 47 and the tap 52 to rotate.

[0048] When the tap 52 rotates, if there is a blockage or too much resistance between the inside of the mounting hole of the auto part and the outer wall of the tap 52, the tap 52 cannot rotate. The rotating wheel 48 pulls all the second pull ropes 46, and the second pull ropes 46 pull and retract all the second elastic telescopic rods 49. When the second elastic telescopic rods 49 retract, they also push the moving block 42 through the connecting arm 45. The moving block 42 moves on the outer wall of the connecting shaft 35, and the moving block 42 drives the abutting tube 39 to move.

[0049] When the abutting tube 39 is released from the outer wall of all the first triangular blocks 43, the movable box 38 is reset and drives the second triangular block 44 to be released from the outer wall of the mating circular block 30. At this time, the mating circular block 30 drives all the inserting blocks 32 to be released from the inside of the through-hole 33, and the rotation of the second triangular block 44 can be stopped immediately to prevent the tap 52 from breaking.

[0050] At this time, the main shaft 6 and the first servo motor 7 are driven to reset. When the first elastic telescopic rod 22 is fully retracted, the push rod 23 will push the matching round block 30, and the matching round block 30 will abut against the outer walls of all the second triangular blocks 44.
