Description

Technical Field

[0001] This invention relates to the field of nut processing technology, specifically to an automatic nut tapping machine. Background Technology

[0002] In the field of machining, nuts are a common type of fastener, and their machining quality directly affects the performance and safety of mechanical equipment. The machining process of nuts mainly includes the key step of tapping, which requires precisely machining threads into the inner hole of the nut.

[0003] Chinese Patent Publication No. 202420994330.6 discloses a nut tapping machine, including a worktable with a material transfer mechanism. The nut to be processed, driven by the material transfer mechanism, enters a transfer mechanism from the discharge end. The transfer mechanism moves the nut to be processed into the clamping range of a clamping mechanism, which then clamps the nut, placing it in the processing position. This achieves the effect of eliminating manual feeding, freeing up manpower, and improving production efficiency through the transfer mechanism. However, this tapping machine suffers from problems such as insecure nut clamping and untimely cleaning.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides an automatic nut tapping machine, which has the following beneficial effects:

[0020] 1. This automatic nut tapping machine utilizes a support assembly and a moving assembly. When the tapping mechanism approaches the nut, the moving assembly continuously applies a pushing force to the clamping assembly. Combined with the first and second clamping blocks and the second spring, the nut is firmly clamped. This eliminates loosening of the nut due to cutting force and vibration, ensures accurate positioning of the tapping tool, and significantly improves the thread machining accuracy.

[0021] 2. This automatic nut tapping machine utilizes a coordinated setup of support, moving, and rotating components. During the tapping process, gear transmission drives the fan blade assembly to rotate, rapidly expelling metal chips. This effectively prevents metal chips from interfering with equipment operation and scratching the nuts, allowing the machine to adapt to long-term continuous operation and the processing of nuts of various specifications, thus expanding its application range.

[0022] 3. This automatic nut tapping machine utilizes the first stop and slide groove on the connecting frame to ensure continuous contact between the sliding seat and the clamping block, while allowing the movable seat to move towards the connecting seat during tapping. This prevents components from being damaged due to excessive force, thereby reducing the probability of equipment failure and extending its service life. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] Please see Figure 1 This embodiment provides an automatic nut tapping machine, which can provide a strong clamping force to the nut before tapping, so as to avoid the nut from loosening during tapping and thus avoid low processing accuracy; at the same time, it can also effectively remove the iron filings generated during nut tapping.

[0032] Specifically, the device includes: a body 1, a drive assembly 2 on the top of the body 1, a support assembly 3 on one side of the drive assembly 2, a tapping mechanism 4 at one end of the support assembly 3, a moving assembly 5 on the support assembly 3, a clamping assembly 6 at the bottom of the tapping mechanism 4, and a rotating assembly 7 at the bottom of the clamping assembly 6.

[0033] Furthermore, the support component 3 is movably connected to the moving component 5, and both the moving component 5 and the clamping component 6 are slidably connected to the body 1, while the clamping component 6 is rotatably connected to the body 1.

[0034] It should be noted that the tapping mechanism 4 is equipped with a motor and a tapping tool at its lower end. During operation, it taps and drills the nut. (This tapping mechanism is existing technology and will not be described in detail further.)

[0035] The working principle is as follows: First, the nut is placed in the clamping assembly 6 for pre-clamping and positioning. Then, the drive assembly 2 is activated, which drives the support assembly 3 to move downwards. As the support assembly 3 moves downwards, it drives the tapping mechanism 4 towards the nut within the clamping assembly 6. Simultaneously, the moving assembly 5 also moves towards the clamping assembly 6 under the influence of the support assembly 3. When the tapping mechanism 4 is about to approach the nut, the moving assembly 5 comes into contact with both the clamping assembly 6 and the rotating assembly 7. At this point, the support assembly 3 provides a resisting force to the moving assembly 5, ensuring continuous contact and a strong pushing force, thus securing the nut within the clamping assembly 6. Then, the support assembly 3 continues to move downwards, and the tapping mechanism 4 taps the nut. During this downward movement, the support assembly 3 also drives the moving assembly 5, causing it to rotate the rotating assembly 7. The rotating assembly 7 effectively removes the metal chips generated during tapping.

[0036] In summary, this automatic nut tapping machine, through its structural design that integrates the support and moving components, ensures that the nut remains clamped during tapping, effectively preventing the nut from loosening and causing low machining accuracy, thus improving the working efficiency of the invention. Furthermore, the coordinated design of the support, moving, and rotating components allows for the effective removal of metal chips generated during tapping, further enhancing the practicality and convenience of the invention.

[0037] Example 2

[0038] Please see Figures 2-5 This embodiment differs from the first embodiment in that it further includes: the drive assembly 2 includes a fixing frame 21 disposed on the top of the body 1, a drive motor 22 disposed on the top of the fixing frame 21, a transmission shaft 23 disposed on the drive motor 22, and a connecting seat 24 disposed on the transmission shaft 23.

[0039] Preferably, the drive motor 22 provides kinetic energy to the drive shaft 23, causing the drive shaft 23 to rotate within the fixed frame 21. The drive shaft 23 has a helical groove, and the connecting seat 24 has a threaded hole that mates with the drive shaft 23; the threaded hole and the helical groove engage. Driven by the drive shaft 23, the connecting seat 24 can move up and down within the fixed frame 21.

[0040] Furthermore, the support assembly 3 includes a connecting frame 31 fixedly disposed on one side of the connecting seat 24, first sliding grooves 32 formed on both sides of the connecting frame 31, a movable seat 33 slidably disposed on the first sliding grooves 32, a movable rod 34 fixedly disposed on the movable seat 33, a first spring 35 disposed on the periphery of the movable rod 34, first stops 36 symmetrically disposed on the connecting frame 31, and two sets of toothed blocks 37 fixedly disposed on one side of the two sets of first stops 36; wherein, the end of the movable rod 34 away from the movable seat 33 passes through the connecting frame 31, and the two ends of the first spring 35 are fixedly connected to the movable seat 33 and the connecting frame 31 respectively.

[0041] Furthermore, the tapping mechanism 4 is fixedly connected to one end of the connecting frame 31 near the first stop 36, and the tapping mechanism 4 is located on the central axis of the two sets of first stops 36.

[0042] Furthermore, the movable component 5 includes a movable rod 51 that is flexibly mounted on the movable seat 33, a sliding seat 52 that is flexibly mounted on the movable rod 51, two sets of second stops 53 that are symmetrically mounted at both ends of the sliding seat 52, two sets of brackets 54 that are symmetrically mounted on the side of the sliding seat 52 away from the second stops 53, and two sets of adjustment parts 55 that are rotatably connected to the second stops 53 and the brackets 54.

[0043] In use, the connecting bracket 31 moves up and down on the machine body 1 under the drive of the connecting seat 24, thereby driving the tapping mechanism 4 to move up and down. The lower end of the movable seat 33 is connected to the moving rod 51. When the connecting bracket 31 moves downward, it drives the moving rod 51 to rotate. At this time, the angle formed between the moving rod 51 and the machine body 1 gradually decreases, thereby pushing the sliding seat 52 to move towards the first clamping block 61. When the tapping mechanism 4 moves towards the clamping assembly 6 under the drive of the connecting bracket 31 and is about to make contact, one end of the sliding seat 52 makes tight contact with one end of the clamping assembly 6, so that the nut is stably fixed in the clamping assembly 6.

[0044] It should be noted that when one end of the sliding seat 52 contacts the clamping assembly 6, the tapping mechanism 4 still needs to descend a certain distance before it can tap the nut. Therefore, in order to keep the sliding seat 52 and the clamping assembly 6 in contact, a limiting component is required. On the other hand, if a path is not provided for the movable seat 33 to move towards the connecting seat 24 during this process, the movable frame will keep pressing against the connecting frame 31, thereby damaging the components.

[0045] By setting a first stop 36 on the connecting frame 31, when the sliding seat 52 just contacts the clamping assembly 6, the first stop 36 abuts against the second stop 53, preventing the sliding seat 52 from moving towards the connecting seat 24, thus keeping the sliding seat 52 and the clamping block in constant contact. By setting a groove 32 on the connecting frame 31, when the tapping mechanism 4 moves downward to tap the nut, since the sliding seat 52 is not fixed at this time, the movable seat 33 moves towards the connecting seat 24 within the groove 32 under the support of the movable frame, effectively preventing the movable frame from constantly pressing against the connecting frame 31 and damaging the components. Under the action of the first spring 35, the movable seat 33 can automatically reset during the upward movement of the tapping mechanism 4 after completing its work, facilitating the next operation.

[0046] It should also be noted that the first stop 36 is in a vertical moving state, and the second stop 53 is in a horizontal moving state. The first stop 36 and the second stop 53 only come into contact when the tapping mechanism 4 is still a short distance away from the nut.

[0047] Furthermore, the adjusting part 55 includes a first gear 551 disposed on one side of the second stop 53, a first reel 552 disposed on the other side of the second stop 53, a belt 553 sleeved on the first reel 552, a second reel 554 sleeved on the end of the belt 553 away from the first reel 552, and a second gear 555 disposed on the second reel; wherein, the first gear 551 meshes with each other on the moving path of the tooth block 37, the first gear 551 is fixedly connected to the first reel 552 through a coupling on the second stop 53, and the second gear 555 is also fixedly connected to the second reel 554 through a coupling on the second stop 53.

[0048] Furthermore, the clamping assembly 6 includes a first clamping block 61 fixedly disposed on the top of the body 1, a second spring 62 disposed on the first clamping block 61, a second clamping block 63 disposed on the end of the second spring 62 away from the first clamping block 61, and a telescopic shaft 64 disposed on the second clamping block 63; wherein the second clamping block 63 is slidably connected to the body 1, and the telescopic shaft 64 is movably connected to the first clamping block 61.

[0049] Furthermore, the tapping mechanism 4 is located at the center when the first clamping block 61 and the second clamping block 63 are combined.

[0050] In use, first push the second clamping block 63 towards the sliding seat 52, then place the nut inside the first clamping block 61 and release the second clamping block 63. Under the force of the second spring 62, the second clamping block 63 moves towards the nut. At this time, the second clamping block 63 and the first clamping block 61 clamp and fix the nut between them, completing the pre-clamping and positioning of the nut. When the sliding seat 52 moves to the second clamping block 63 and contacts it, it will apply pressure to the second clamping block 63 towards the first clamping block 61, making the nut more stably fixed between the first clamping block 61 and the second clamping block 63.

[0051] Furthermore, the rotating assembly 7 includes a rotating shaft 71 disposed inside the body 1, two sets of third gears 72 symmetrically disposed on the rotating shaft 71, and a fan blade assembly 73 disposed between the two sets of third gears 72; wherein, the third gears 72 mesh with the second gear 555 in the movement path of the second gear 555, and the fan blade assembly 73 is located below the first clamping block 61 and the second clamping block 63.

[0052] When tapping the nut, the tapping mechanism 4 first moves from the upper surface of the nut to the lower surface for processing. Simultaneously, the connecting frame 31 drives the toothed block 37 downwards. During the downward movement of the toothed block 37, two sets of first gears 551 rotate. These first gears 551 then drive two sets of belts 553, which are fitted onto the first and second winding pulleys 552 and 554, to rotate. The rotation of the belts 553 drives two sets of second gears 555, which in turn drives the third gear 72. Finally, the third gear 72 drives the fan blade assembly 73 to rotate. Since the fan blade assembly 73 is located at the lower end of the clamping assembly 6, it can discharge the metal chips generated during the tapping process towards the cutting opening. Therefore, this invention achieves stable clamping of the nut and cleaning of metal chips generated during the tapping process solely through the operation of the drive motor 22, thereby improving work efficiency and effectively reducing operating costs.

[0053] Furthermore, the top of the machine body 1 is provided with a guide rail 11 to facilitate the movement of the sliding seat 52, and the two sides of the guide rail 11 are provided with slots 12 to facilitate the movement of the adjustment part 55. The machine body 1 is also provided with a discharge port 13 at the position of the rotating component 7.

[0054] The working principle is as follows: First, the nut is placed in the clamping assembly 6 for pre-clamping and positioning. Then, the drive assembly 2 is activated, which drives the support assembly 3 to move downwards. As the support assembly 3 moves downwards, it drives the tapping mechanism 4 towards the nut within the clamping assembly 6. Simultaneously, the moving assembly 5 also moves towards the clamping assembly 6 under the influence of the support assembly 3. When the tapping mechanism 4 is about to approach the nut, the moving assembly 5 comes into contact with both the clamping assembly 6 and the rotating assembly 7. At this point, the support assembly 3 provides a resisting force to the moving assembly 5, ensuring continuous contact and a strong pushing force, thus securing the nut within the clamping assembly 6. Then, the support assembly 3 continues to move downwards, and the tapping mechanism 4 taps the nut. During this downward movement, the support assembly 3 also drives the moving assembly 5, causing it to rotate the rotating assembly 7. The rotating assembly 7 effectively removes the metal chips generated during tapping.

[0055] In summary, this automatic nut tapping machine utilizes a support assembly and a moving assembly. When the tapping mechanism approaches the nut, the moving assembly continuously applies a pushing force to the clamping assembly, which, combined with the first and second clamping blocks and the second spring, firmly clamps the nut. This eliminates loosening of the nut due to cutting force and vibration, ensures precise tapping tool positioning, and significantly improves thread processing accuracy. The coordinated arrangement of the support assembly, moving assembly, and rotating assembly, along with gear transmission driving the fan blade assembly to rotate during tapping, quickly discharges metal chips. This effectively prevents metal chips from interfering with equipment operation and scratching the nut, allowing the machine to adapt to long-term continuous operation and the processing of nuts of various specifications, thus expanding its application range. The first stop and sliding groove on the connecting frame ensure continuous contact between the sliding seat and the clamping block while allowing the movable seat to move towards the connecting seat during tapping, preventing damage to components due to excessive force. This reduces the probability of equipment failure and extends its service life.
