Description

Technical Field

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

[0002] In the trend of the intelligent and efficient development of the automobile manufacturing industry, the production precision and processing efficiency of automobile parts have become the core indicators to measure the competitiveness of enterprises. As a key process in the manufacturing of automobile parts, the processing quality of tapping directly affects the assembly reliability of components and the performance of the whole vehicle. With the increasing demand for diversification and customization of parts in the automobile industry, the tapping equipment needs to meet the dual requirements of high-precision processing and rapid switching of production tasks at the same time; Currently, there are significant technical bottlenecks in the actual application of traditional automobile part tapping equipment. On the one hand, during the tapping operation, if there are internal defects in the workpiece material, chip jams, or bottom hole size deviations, etc., the tap is extremely prone to jamming. Since the existing equipment lacks an intelligent torque monitoring and emergency response mechanism, the power system still continuously transmits torque, resulting in the tap bearing overload stress and frequently breaking. This not only greatly increases the tool wear cost, but also seriously affects the production continuity due to downtime for maintenance. On the other hand, the workpiece fixing method of traditional equipment mostly uses general fixtures, which are difficult to quickly adapt to different specifications of parts, and the fixed position is likely to block the hole positions to be processed, requiring repeated adjustment of the clamping position, which not only reduces the processing efficiency, but also may affect the tapping precision due to positioning deviation. In addition, the manual clamping process depends on the experience of operators, with problems such as uneven clamping force and long time consumption, and cannot meet the mass production and high-precision production requirements of automobile parts; Therefore, it is extremely urgent to develop a tapping device for automobile parts that integrates intelligent anti-breaking protection and quick and accurate clamping. This device needs to achieve automatic shaft breaking protection when the tap jams, and at the same time have flexible and efficient workpiece fixing and quick adjustment functions to improve the reliability, efficiency, and automation level of automobile part tapping processing.

[0003] After retrieval, it is found that the prior art publication number is CN116275314A, which discloses a tapping device including a support base. A first support plate is installed on the left surface of the support base, and a second support plate is installed above the first support plate on the left surface of the support base. A first adjustment mechanism is arranged on the upper surface of the support base, a second adjustment mechanism is arranged at the upper end of the first adjustment mechanism, and an installation mechanism is arranged at the upper end of the second adjustment mechanism. Through the arranged first adjustment mechanism, the position of the workpiece can be quickly adjusted in the left-right direction, the second adjustment mechanism can quickly adjust the position of the workpiece in the front-back direction, and the third motor in the installation mechanism drives the synchronous belt to rotate, enabling the two clamping plates to approach until the workpiece is fixed. The two clamping plates can firmly fix the workpiece, clamp and fix the workpiece on the side, without blocking the hole to be tapped, and the fixation process is very simple and convenient by driving with the third motor.

[0004] Therefore, based on the above retrieval and in combination with the existing ones, in the above device, the second adjustment mechanism supports the quick front-back positioning of the workpiece. The third motor in the installation mechanism drives the synchronous belt, enabling the two clamping plates to smoothly approach and fix the workpiece. The side clamping method not only ensures firm fixation but also does not block the tapping hole position. However, it cannot stop the rotation of the tap for protection when the tap is overloaded during tapping, which has limitations. For this reason, we propose a quick-adjustment tapping device for auto parts. Summary of the Invention

[0005] The purpose of the present invention is to provide a quick-adjustment tapping device for auto parts to solve the problems raised in the above background technology.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: A quick-adjustment tapping device for auto parts includes a machine tool. An installation base is fixedly connected inside the machine tool. A moving slide plate is slidably connected to the upper end of the installation base. A limiting mechanism for clamping, fixing, and limiting the auto parts is fixedly installed between the moving slide plate and the installation base. A first servo motor is also fixedly installed at the upper end of the installation base. The output end of the first servo motor is fixedly connected to a main shaft. A trigger mechanism and an intelligent monitoring mechanism are fixedly connected to the end of the main shaft away from the first servo motor. The main shaft is fixedly connected to a tap through the intelligent monitoring mechanism. The first servo motor drives the trigger mechanism and the intelligent monitoring mechanism to rotate through the main shaft, thereby driving the tap to rotate. The tap will tap the tooling hole of the auto parts. When the intelligent monitoring mechanism detects that the tap is stuck, it will immediately trigger the trigger mechanism to relieve the force on the tap to prevent the tap from breaking.

[0007] As a further aspect of this solution, the limiting mechanism includes a second servo motor, which is fixedly connected to the upper end of the moving slide plate. The output end of the second servo motor is fixedly connected with a threaded rod, and the outer wall of the threaded rod is threadedly connected to the inside of the moving slide plate. The upper end of the mounting base is fixedly connected with a fixing frame, and the upper end of the fixing frame is slidably connected with two abutting blocks with a reset function. One end of each of the two abutting blocks facing each other is fixedly connected with a threaded tube, and the outer wall of each threaded tube is threadedly connected with a matching fixing block. By replacing the matching fixing blocks of different sizes, the fixing and clamping of automotive parts of different sizes can be adjusted.

[0008] As a further aspect of this solution, one end of each of the two abutting blocks facing away from each other is fixedly connected with a connecting rod, and the upper end of the moving slide plate is fixedly connected with two first connecting plates. One end of each first connecting plate away from the moving slide plate is fixedly connected with an abutting inclined plate.

[0009] As a further aspect of this solution, the triggering mechanism includes a second connecting plate, which is fixedly connected to the main shaft. One end of the second connecting plate away from the main shaft is fixedly connected with a first elastic telescopic rod, and one end of the first elastic telescopic rod away from the third elastic telescopic rod is fixedly connected with a second connecting circular plate, and a plurality of matching holes are formed in the inside of the second connecting circular plate.

[0010] As a further aspect of this solution, one end of the second connecting plate close to the second connecting circular plate is fixedly connected with a plurality of push rods, and one end of the second connecting circular plate away from the first elastic telescopic rod is fixedly connected with a sliding rectangular rod. A matching circular block with a reset function is slidably connected to the outer wall of the sliding rectangular rod. One end of the matching circular block away from the second connecting circular plate is fixedly connected with a plurality of insertion blocks, and one end of the matching circular block away from the insertion blocks is fixedly connected with a fixed circular plate through a plurality of connecting rectangular plates.

[0011] As a further aspect of this solution, a moving box with a reset function is slidably connected to the inside of each connecting rectangular plate, a second triangular block with a reset function is slidably connected to the inside of all the moving boxes, and a first triangular block is also fixedly connected to the outer wall of all the moving boxes. An abutting tube is arranged between all the first triangular blocks, and the inner wall of the abutting tube abuts against the outer walls of all the first triangular blocks.

[0012] As a further aspect of this solution, the intelligent monitoring mechanism includes a third connecting circular plate, and a plurality of through holes are formed in the inside of the third connecting circular plate. The outer wall of each insertion block passes through the inside of the corresponding through hole, and an intelligent sensor is installed in each through hole. When the insertion block is not inserted into the through hole, an alarm will be issued to prompt the staff to check and correct immediately. A connecting shaft is fixedly connected to the outer wall of the third connecting circular plate.

[0013] Further in this solution, a rotating wheel is fixedly connected to one end of the connecting shaft away from the third connecting circular plate, and a connecting ring is arranged on the outer side of the rotating wheel.

[0014] Further in this solution, a plurality of second elastic telescopic rods are fixedly connected to the outer wall of the connecting ring. A second pull rope is fixedly connected between the inner wall of each second elastic telescopic rod and the outer wall of the rotating wheel. A moving block is slidably connected to the outer wall of the connecting shaft. Each second elastic telescopic rod is rotatably connected to the moving block through a plurality of connecting arms.

[0015] Further in this solution, the tap is fixedly connected to the connecting ring. Beneficial effects

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. During use, place the automotive parts on the fixed frame, start the second servo motor to drive the threaded rod to rotate, and drive the moving slide plate to displace. During this process, the abutting wheel slides along the abutting inclined plate, prompting the two abutting blocks to approach each other, realizing the stable clamping of the automotive parts. Through automatic positioning and clamping, there is no need for manual adjustment repeatedly, significantly improving the clamping efficiency. The parts are fixed in a symmetrically shrinking manner, with uniform force, which can effectively avoid the machining deviation of the parts caused by unstable clamping. 2. The first servo motor drives each component to rotate cooperatively in sequence, and finally drives the tap to process the automotive parts. When the tap cannot rotate due to chip blockage or excessive resistance during operation, the intelligent protection mechanism is triggered: the rotating wheel pulls the second pull rope, causing the second elastic telescopic rod to contract, and then pushing the moving block to drive the abutting pipe to move, cutting off the transmission connection, so that the tap stops rotating quickly, realizing stable and efficient tapping transmission. It can also respond quickly under abnormal working conditions. By automatically disconnecting the transmission path, it avoids the tap from breaking due to overload, effectively protecting the tool life, reducing the downtime maintenance cost, and at the same time improving the safety and processing continuity of the equipment operation.

A communicating circular ring 19 is rotatably connected to the outer wall of the first connecting circular plate 18. The communicating circular ring 19 is connected and communicated with the first connecting circular plate 18. Specifically, a cavity is formed inside the communicating circular ring 19, and a plurality of air through holes are further formed on the inner wall of the communicating circular ring 19. Each air through hole is communicated with the cavity. (For details, please refer to Figure 11),(the outer wall of the first connecting circular plate 18 is communicated with a first rubber corrugated sleeve 20. A third spring is fixedly connected inside the first rubber corrugated sleeve 20. The first rubber corrugated sleeve 20 is made of rubber material. The first rubber corrugated sleeve 20 is located inside the third elastic telescopic rod 17. The left end of the inner wall of the third elastic telescopic rod 17 is fixedly connected with an abutting round rod 21. One end of the fixed circular plate 31 close to the first elastic telescopic rod 22 is fixedly connected with a plurality of second rubber corrugated sleeves 26. The plurality of second rubber corrugated sleeves 26 are circumferentially distributed on the outer wall of the fixed circular plate 31.

The connecting circular ring 27 and the abutting pipe 39 are fixedly connected by a plurality of first pulling ropes 36. The plurality of first pulling ropes 36 are circumferentially distributed between the connecting circular ring 27 and the abutting pipe 39; Specifically, start the first servo motor 7 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 inserting 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 a plurality of second pulling 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 for tapping the inner wall of the tooling hole of the auto parts, due to the long service time of the tap 52, wear and bluntness will occur. When tapping and moving at the same speed, the third elastic telescopic rod 17 will contract. When the abutting round rod 21 abuts against the outer wall of the first rubber corrugated sleeve 20, the first rubber corrugated sleeve 20 contracts. The gas inside the first rubber corrugated sleeve 20 enters the communicating circular ring 19 through the first connecting circular plate 18, and then enters all the second rubber corrugated sleeves 26 through the communicating circular ring 19. The second rubber corrugated sleeve 26 drives the connecting circular ring 27 to move. The connecting circular ring 27 will pull all the first pulling ropes 36. The first pulling ropes 36 will pull the abutting pipe 39. When the abutting pipe 39 disengages from the outer wall of all the first triangular blocks 43, the moving box 38 resets to drive the second triangular block 44 to disengage from 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 will drive all the inserting blocks 32 to disengage from the through hole 33, and the rotation of the second triangular block 44 can be immediately stopped to avoid the fracture of the second triangular block 44; At this time, continue to drive the main shaft 6 and the first servo motor 7 to move, and continue to squeeze the third elastic telescopic rod 17. After the third elastic telescopic rod 17 is completely contracted, the first elastic telescopic rod 22 contracts later. All the push rods 23 will pass through the inside of the fitting hole 24 and abut against the outer wall of the fitting round block 30 to push. At this time, when the fitting 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 and contracts into the moving box 38. When the fitting round block 30 disengages from the outer wall of the second triangular block 44, drive the main shaft 6 and the first servo motor 7 to reset. The fifth spring 29 drives the fitting round block 30 to reset and abut against the outer walls of all the second triangular blocks 44. All the plug blocks 32 will re-engage with the corresponding through holes 33. If they cannot be engaged, just drive the through holes 33 to adjust the angle. Subsequently, the third elastic telescopic rod 17 loses compression, and the abutting round rod 21 disengages from 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. The second rubber corrugated sleeve 26 will release the tension on the first pulling rope 36. When all the rotating wheels 48 are reset, the abutting pipe 39 will be reset through the connecting arm 45 and the moving block 42 to drive the abutting pipe 39 to reset again. The tap 52 rotates in the reverse direction, and the tap 52 can be taken out and replaced.

[0032] The working principle of the present invention is: when in use, place the automotive parts on the upper end of the fixed frame 50, start the second servo motor 10, the second servo motor 10 drives the threaded rod 41 to rotate, and the threaded rod 41 drives the moving slide plate 8 to move. When the abutting wheels 11 move along the outer wall of the abutting inclined plate 15 towards the outer wall of the first connecting plate 16, the two abutting wheels 11 will drive the two abutting blocks 14 to approach and contract through the connecting rod 12. The abutting blocks 14 fix the automotive parts. At this time, the moving slide plate 8 can be driven to move back and forth. Start the first servo motor 7, and 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 fitting hole 24 and the sliding rectangular rod 28 to rotate. The sliding rectangular rod 28 drives the fitting round block 30 to rotate. The fitting round block 30 drives the third connecting circular plate 34 to rotate through the plug 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 pulling ropes 46. The second elastic telescopic rod 49 drives the connecting ring 47 and the tap 52 to rotate; When the tap 52 rotates, if there is a blockage or excessive resistance between the inner wall of the installation hole of the automotive parts and the outer wall of the tap 52, and at this time the tap 52 cannot rotate, the rotating wheel 48 will pull all the second pull ropes 46. The second pull ropes 46 will pull and contract all the second elastic telescopic rods 49. When the second elastic telescopic rods 49 contract, they will also push the moving block 42 through the connecting arm 45. The moving block 42 will move on the outer wall of the connecting shaft 35, and the moving block 42 will drive the abutting pipe 39 to move; When the abutting pipe 39 disengages from the outer wall abutment of all the first triangular blocks 43, the moving box 38 resets and drives the second triangular block 44 to disengage from the outer wall abutment of the mating circular block 30. At this time, the mating circular block 30 will drive all the plug blocks 32 out of the inside of the through holes 33, and the rotation of the second triangular block 44 can be immediately stopped to avoid breakage of the tap 52; 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 contracted, the push rod 23 will push the mating circular block 30. The mating circular block 30 will abut against the outer walls of all the second triangular blocks 44. When the abutment is disengaged, the outer walls of all the plug blocks 32 will be clamped with the inner walls of all the through holes 33. According to the above working principle, driving the second triangular block 44 to rotate in the reverse direction can remove the second triangular block 44 and replace it.
