Description

Technical Field

[0001] The present invention relates to the technical field of thread processing, and particularly to a metal rotary head nut tapping machine for a perforator. Background Art

[0002] In the traditional tapping process, after the threading tool head cuts and forms the threads on the inner wall of the nut, the tool head needs to rotate in the reverse direction and exit the nut along the thread trajectory so that the nut can be taken out; this results in:

[0003] 1. The cutting edge of the tool head is relatively sharp. During the exit process, the cutting edge will inevitably scrape against the formed threads, resulting in thread damage and affecting the final quality of nut tapping.

[0004] 2. After tapping is completed, there are iron chips in the thread gaps. During the exit process of the tool head, there is a risk of squeezing the iron chips and causing the iron chips to embed in the thread wall under the action of the squeezing force, resulting in a possible jamming phenomenon during the use of the nut.

[0005] 3. During the exit process of the tool head, the faster the exit speed, the greater the squeezing force on the iron chips. Correspondingly, the greater the risk of the iron chips embedding in the thread wall, resulting in a limited exit speed of the tool head and a decrease in processing efficiency.

[0032] Please refer to Figures 1-6 , the present invention provides a technical solution: A metal rotary head nut tapping machine for a drilling machine, including a machine table 1 and a machine body 2, further including a main shaft 3, a tap 4 and a sub-shaft 5; The main shaft 3 is fixedly connected to the output shaft of the machine body 2; At both the upper and lower ends of the tap 4, there are pins 6, and at the lower end of the main shaft 3 and the upper end of the sub-shaft 5, there are slots 7 that can engage the pins 6 respectively, and the upper and lower ends of the tap 4 can be locked with the main shaft 3 and the sub-shaft 5 respectively;

[0033] It further includes a clamping assembly, a driving assembly and a control assembly;

[0034] The clamping assembly is used for clamping nuts, and the clamping assembly is provided with a transmission mechanism;

[0035] The driving assembly is arranged at the lower end of the machine table 1 and is rotatably connected to the lower end of the sub-shaft 5, and the driving assembly is used to control the vertical displacement of the sub-shaft 5;

[0036] The control assembly is used to control the locking between the tap 4 and the main shaft 3 and the sub-shaft 5; The control assembly can, after the tap 4 finishes tapping, control the cancellation of the locked state between the tap 4 and the main shaft 3, and when clamping the nut, control the tap 4 to disengage from the locked state with the sub-shaft 5;

[0037] The transmission mechanism can lock the nut by the clamping assembly after the main shaft 3 moves down to the first predetermined height and during the downward movement of the sub-shaft 5, and cancel the locking of the nut after the main shaft 3 moves up to the second predetermined height.

[0038] Refer to Figure 6, the device working process is a - b - c - d - e - a, with state a as the initial state:

[0039] State a: The tap 4 is locked to the lower end of the main shaft 3, and the tap 4 is separated from the upper end of the auxiliary shaft 5; then the nut is sleeved on the auxiliary shaft 5, and the nut is centered through the auxiliary shaft 5 to improve the coaxiality between the inner hole of the nut and the tap 4, avoiding the low coaxiality between the inner hole of the nut and the tap 4 caused by the manufacturing tolerance of the nut and the piercing tolerance, resulting in inconsistent thread depths of the nut in the final processing and affecting the production quality of the nut;

[0040] State b: Then the machine body 2 controls the main shaft 3 to drive the tap 4 to move downwards and make the pin 6 at the lower end of the tap 4 dock with the slot 7 at the upper end of the auxiliary shaft 5. After the docking is completed (at this time, the main shaft 3 moves down to the first predetermined height), the control component controls the tap 4 and the auxiliary shaft 5 to be locked;

[0041] State c: Then the main shaft 3 drives the tap 4 to rotate and move downwards to tap the nut (during this process, as the main shaft 3 enters the threaded hole of the nut, the main shaft 3 can fit against the inner wall of the threaded hole to center the threaded hole), and at the same time the driving component drives the auxiliary shaft 5 to move downwards synchronously. During the downward movement of the auxiliary shaft 5, the clamping component clamps the nut, so that the tapping process proceeds smoothly; until the tap 4 moves below the nut and the threading on the inner wall of the nut is completed;

[0042] State d: At this time, the control component controls the cancellation of the locked state between the tap 4 and the main shaft 3. At the same time, the main shaft 3 stops rotating and moves upwards to disengage from the tap 4 and the nut. Until it moves up to the second predetermined height, the clamping component is controlled by the transmission mechanism to cancel the locking of the nut, so that the nut can be taken out;

[0043] State e: After the nut is taken out, the auxiliary shaft 5 drives the tap 4 to move upwards to the initial position of the auxiliary shaft 5, and at the same time the main shaft 3 moves downwards to dock with the tap 4; after the main shaft 3 and the tap 4 are docked, the control component controls the locking between the tap 4 and the main shaft 3, and at the same time controls the cancellation of the locked state between the tap 4 and the auxiliary shaft 5;

[0044] Then the main shaft 3 drives the tap 4 to move upwards to the initial position, providing space for the process of sleeving the nut onto the auxiliary shaft 5; thus, tapping is carried out again.

[0045] In the present invention, a secondary shaft 5 capable of locking with a tap 4 is provided. After the tapping of the tap 4 is completed, the tap 4 is directly connected to the secondary shaft 5, so that the main shaft 3 is disengaged from the tap 4. Furthermore, after the tapping is completed, the main shaft 3 can be directly lifted upward to disengage from the nut, so that the removal of the nut will not be interfered by the tool, avoiding the action of the tap 4 retracting along the original path from the nut, and preventing the tap 4 from directly damaging the thread due to passing through the thread twice or indirectly damaging the thread by squeezing iron filings during the machining process, effectively improving the machining quality of the thread. At the same time, after the tapping is completed, the components of the equipment are reset for re-tapping, which will not damage the nut, and its reset speed will not be restricted, enabling rapid reset, thus greatly accelerating the working efficiency of the batch tapping process.

[0046] The clamping assembly includes clamping plates 8 symmetrically arranged on the left and right with respect to the secondary shaft 5. The machine table 1 is provided with sliding grooves 9 corresponding to the lower sides of the clamping plates 8. The lower ends of the clamping plates 8 are fixedly connected with slider ones 10, and the slider ones 10 are slidably connected with the sliding grooves 9. One ends of the clamping plates 8 far from the secondary shaft 5 are fixedly connected with elastic members one 11, and the elastic members one 11 are fixedly connected with the machine table 1. The sliding grooves 9 are slidably connected with slider twos 12, the slider twos 12 are fixedly connected with elastic members two 13, and the elastic members two 13 are fixedly connected with a pressing plate 14, and the pressing plate 14 can press the slider ones 10; the transmission mechanism can drive the slider twos 12 to move towards the secondary shaft 5 as the main shaft 3 moves downward, and the transmission mechanism can prevent the pressing plate 14 from pressing the slider ones 10 before the secondary shaft 5 moves downward.

[0047] The elastic force of the elastic member two 13 is much greater than that of the elastic member one 11. During the process of the equipment in Figure 6 state a, the nut is clamped by the elastic force of the elastic member one 11, so that the side wall of the nut fits with the clamping plate 8;

[0048] Then, during the downward movement of the main shaft 3, the transmission mechanism moves downward with the main shaft 3 to control the slider twos 12 to move towards the secondary shaft 5, so that the slider twos 12 drive the pressing plate 14 to move towards the secondary shaft 5 through the elastic members two 13 until the pressing plate 14 encounters an obstacle and cannot move further. At this time, the elastic members two 13 are compressed, so that the pressing plate 14 has a force pressing towards the secondary shaft 5, and the pressing force increases as the slider twos 12 move towards the secondary shaft 5. At this time, under the action of the transmission mechanism, the pressing plate 14 cannot press the slider ones 10;

[0049] Until the equipment starts to be in Figure 6During the process from state b to state c, the auxiliary shaft 5 moves downward, and the device starts tapping. During this process, the transmission mechanism no longer obstructs the pressing plate 14 from squeezing the first slider 10. Under the elastic force of the second elastic member 13, the first slider 10 squeezes the nut to clamp the nut, thereby ensuring that the nut does not rotate during the tapping process (the nut is centered by sleeving the nut on the auxiliary shaft 5, and then clamped by the pressing plate 14 to restrict the rotation of the nut, and the nut is clamped). Then, with the completion of tapping, the device enters state d, the main shaft 3 moves upward, the second slider 12 moves away from the auxiliary shaft 5, and drives the second elastic member 13 and the pressing plate 14 to move away from the auxiliary shaft 5, so that the pressing plate 14 is only squeezed by the first elastic member 11, and thus the pressing plate 14 can be easily pushed, enabling the nut to be taken out smoothly.

[0050] By using the transmission mechanism, the clamping assembly controls the clamping of the nut through the main shaft 3 and the auxiliary shaft 5, enabling the device to complete automatic clamping, and the means is stable and reliable. At the same time, the transmission mechanism obstructs the pressing plate 14 from squeezing the first slider 10, so that the pressing plate 14 is tightened only when tapping starts, effectively increasing the time range of nut loading during the operation of the device and effectively improving the processing efficiency.

[0051] The transmission mechanism includes a main rod 15 arranged horizontally. The machine body 2 includes a fuselage 2-1, and the fuselage 2-1 is fixedly connected to the machine table 1. A working part 2-2 is vertically slidably connected to the fuselage 2-1. The main shaft 3 is arranged at the lower end of the working part 2-2. The working part 2-2 can perform vertical displacement relative to the fuselage 2-1. The main rod 15 is fixedly connected to the lower end of the working part 2-2. Vertical connecting rods one 16 are fixedly connected to both ends of the main rod 15. A through groove 17 is formed in the machine table 1 below the connecting rod one 16. An inclined connecting rod two 18 is arranged in the through groove 17, and the lower end of the connecting rod two 18 is closer to the auxiliary shaft 5 than the upper end; the upper end of the connecting rod two 18 is rotatably connected to the lower end of the connecting rod one 16. A third slider 19 is horizontally slidably connected to the lower end of the machine table 1. The third slider 19 is rotatably connected to the lower end of the connecting rod two 18. The third slider 19 is fixedly connected to a first connecting plate 20, and the first connecting plate 20 is fixedly connected to the first slider 10 on the same side; a blocking assembly is arranged on the driving assembly, and the blocking assembly is used to prevent the pressing plate 14 from squeezing the second slider 12.

[0052] When the device goes from state a through state b to state c, the working part 2-2 drives the main shaft 3 to continuously move downward. During this process, the working part 2-2 drives the main rod 15 to move vertically downward, so that the main rod 15 drives the connecting rod one 16 to move vertically downward. Then, the upper end of the connecting rod two 18 rotatably connected to the lower end of the connecting rod one 16 also moves downward. Since the lower end of the connecting rod two 18 is rotatably connected to the third slider 19, the lower end of the connecting rod two 18 can only move horizontally. Further, as the upper end of the connecting rod two 18 continuously moves downward, the lower end of the connecting rod two 18 drives the third slider 19 to move towards the auxiliary shaft 5, and then drives the second slider 12 to move towards the auxiliary shaft 5.

[0053] The driving assembly includes a fixedly arranged driving member 21, an installation plate 22 is arranged at the upper end of the driving member 21, and the driving member 21 is used to drive the vertical displacement of the installation plate 22; the lower end of the secondary shaft 5 is rotatably connected to the upper end of the installation plate 22.

[0054] The blocking assembly includes two symmetrically arranged connecting plates two 23 fixedly connected to both sides of the installation plate 22, and a partition one 24 is arranged at the upper end of the connecting plate two 23; the partition one 24 is used to prevent the pressing plate 14 from moving towards the secondary shaft 5.

[0055] Before the secondary shaft 5 moves downward, correspondingly, the partition one 24 coincides with the pressing plate 14 in the vertical direction. When the pressing plate 14 moves towards the secondary shaft 5, it will be blocked by the partition one 24; when the secondary shaft 5 moves downward, the corresponding installation plate 22 will drive the partition one 24 to move downward, so that the partition one 24 is separated from the moving track of the pressing plate 14, and then the pressing plate 14 can squeeze the slider one 10, and then the clamping plate 8 clamps.

[0056] A chamfer one 24-1 is provided on the side of the partition one 24 close to the pressing plate 14, and a chamfer two 14-1 is provided on the side of the pressing plate 14 close to the partition one 24.

[0057] By setting the chamfer, when the partition one 24 moves downward and is separated from the moving track of the pressing plate 14, the pressing plate 14 can move towards the slider one 10 along the chamfer track, thereby reducing the distance of the pressing plate 14 impacting the slider one 10 under the action of elastic force, and then reducing the impact of the pressing plate 14 on the slider one 10 and improving the stability of the equipment.

[0058] Longitudinally slidable connecting plates two 25 are connected to the upper ends of the connecting plates two 23 on the side of the partition one 24 close to the secondary shaft 5. An elastic member three 26 is fixedly connected between the partition one 24 and the connecting plates two 25. A locking member is externally connected to the partition one 24, and the locking member can lock the partition one 24 and the connecting plates two 23 when the elastic member three 26 is compressed to the limit.

[0059] The elastic force of the elastic member three 26 is much smaller than that of the elastic member two 13. When the secondary shaft 5 does not move downward, when the pressing plate 14 moves towards the slider one 10, first the pressing plate 14 squeezes the partition one 24, so that the partition one 24 drives the connecting plates two 25 to move towards the slider one 10 through the elastic member three 26 until the connecting plates two 25 are in contact with the slider one 10. Then the partition one 24 continues to move towards the slider one 10 with the pressing plate 14, so that the elastic member three 26 is compressed. When the elastic member three 26 is compressed to the limit, the locking member locks the partition one 24 and the connecting plates two 23, so that the pressing plate 14 cannot continue to move towards the slider one 10, avoiding the slider one 10 being squeezed by the pressing plate 14; during this process, the elastic member three 26 and the connecting plates two 25 exist as triggering parts for fixing the partition one 24, making the partition one 24 as close to the slider one 10 as possible before being fixed, thereby reducing the subsequent impact of the pressing plate 14 on the slider one 10.

[0060] The control component includes an electromagnet externally and internally connected to the slot 7, and the electromagnet is used to adsorb the pin 6.

[0061] The main shaft 3 includes a first base shaft 3-1, the slot 7 is opened at the lower end of the first base shaft 3-1, a first sleeve 3-2 is sleeved on the first base shaft 3-1, and a discharge groove 3-2-1 is vertically opened in the first sleeve 3-2.

[0062] The auxiliary shaft 5 includes a second base shaft 5-1, the second base shaft 5-1 is rotatably connected to the mounting plate 22, the slot 7 is opened at the upper end of the second base shaft 5-1, and a second sleeve 5-2 is sleeved on the second base shaft 5-1.

[0063] Through the sleeved first sleeve 3-2 and second sleeve 5-2, the device can flexibly replace the first sleeve 3-2 and the second sleeve 5-2 according to the size of the processed nut.
