[0002] Tapping is the process of machining precise internal threads into products made of metal or other materials, so that they can be connected and secured with screws, bolts, etc. (See attached image) Figure 6 The product shown, namely the metal ring 100, includes an upper ring 101 and a lower ring 102 connected vertically. The lower end of the upper ring 101 protrudes laterally from the upper end of the lower ring 102. During tapping, an internal thread needs to be machined on the side wall of the cavity 1010 of the upper ring 101.

[0003] In the prior art, such as a rotary tapping machine with application number 201520958357.0, one end of the feeding track is connected to a vibrating plate, and the other end is close to the rotary plate. The tapping action can be completed during continuous feeding through the connection of the rotary plate. The rotary plate has a material-holding hole penetrating its body for positioning the nut to be tapped. As shown in the figure, the part of the nut that needs to be tapped abuts against the upper surface of the rotary plate to support the nut. However, for the attached... Figure 6 The metal ring 100 shown has an upper ring 101 with a certain height or a relatively high height. When it is supported on the upper surface of the turntable, its periphery lacks a structure to limit and position it, which will lead to instability of the load to a certain extent.

[0004] The purpose of this utility model is to provide a feeding structure for tapping and a tapping device having the same. A positioning groove is set on the rotating disk that runs vertically through the main body, and a support platform for positioning a metal ring is set in the positioning groove. The upper ring of the metal ring can be limited and supported, and the lower ring can be limited. By positioning the metal ring at multiple positions, the stability of the metal ring in the positioning groove can be ensured, which facilitates stable tapping of the metal ring.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a feeding structure for tapping, comprising:

[0006] A vibrating feeding mechanism is used for conveying and feeding products.

[0007] The transfer feeding mechanism includes a rotating table and a rotating disk mounted on the rotating table.

The positioning slots are connected to the vibrating feeding mechanism at the feeding position to accommodate products and to support the products via the support platforms.

[0008] The unloading mechanism includes a bracket and a pusher plate disposed on the bracket. The pusher plate is located above the rotary disk and has a baffle arc surface at one end away from the bracket. The baffle arc surface is located at the unloading position and is configured to slide against the product when the product is moved to the unloading position to push the product out of the positioning groove.

[0009] As a further optimization, the rotating disk includes an upper disk and a lower disk connected together. The upper disk includes a first disk body and first teeth formed on the first disk body at equal intervals. A first slot is formed between an adjacent pair of first teeth. The lower disk includes a second disk body and second teeth formed on the second disk body at equal intervals. A second slot is formed between an adjacent pair of second teeth. The first slot and the second slot are vertically connected to form the positioning groove. The portion of the vertical projection of the second teeth that is located within the vertical projection of the first slot forms the support platform.

[0010] As a further optimization, the support platform is located on opposite sides within the positioning groove, and closer to the open end of the positioning groove.

[0011] As a further optimization, the side wall of the second disc is provided with an auxiliary positioning platform that extends into the second slot and protrudes from the first slot, and there is a gap between the auxiliary positioning platform and the support platform.

[0027] Figure 6 This is a structural diagram of the product. Detailed Implementation

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] like Figures 1 to 5As shown, a tapping feeding structure includes a vibratory feeding mechanism 10, a transfer feeding mechanism 20, and a discharging mechanism 30. The vibratory feeding mechanism 10 is used to feed products. The transfer feeding mechanism 20 includes a rotary table 21 and a rotary disk 22 disposed on the rotary table 21. The rotary disk 22 has multiple vertically penetrating positioning slots 200 evenly spaced on its side, and a support platform 202a is provided in the positioning slot. The positioning slot 200 is connected to the vibratory feeding mechanism 10 at the feeding position to accommodate the product and support the product through the support platform 202. The discharging mechanism 30 includes a bracket 31 and a pusher plate 32 disposed on the bracket 31. The pusher plate 32 is located above the rotary disk 22, and a blocking arc surface 320 is provided at its end away from the bracket. The blocking arc surface 320 is located at the discharging position and is configured to slide against the product when it is driven to the discharging position, thereby pushing the product out of the positioning slot 200.

[0030] Combination Figure 6As shown, the product requiring feeding in this invention is a metal ring 100. The metal ring 100 includes an upper ring 101 and a lower ring 102 connected vertically. The outer diameter of the upper ring 101 is larger than the outer diameter of the lower ring 102, and the two are connected. The metal ring 100 needs to undergo tapping within the cavity 101 of its upper ring 101 to meet the requirements of the finished product or subsequent use. To improve the tapping efficiency of the metal ring 100, an automatic feeding method can be used to feed the metal ring 100 and perform tapping during the feeding process. For feeding the metal rings 100, they can be fed one by one by the vibrating feeding mechanism 10. When the metal rings 100 are conveyed to the feeding position, they can first slide or roll against the side wall of the rotating disk 22 to keep their position unchanged. After the rotating table 21 drives the rotating disk 22 to rotate so that the positioning groove 200 can be connected with the vibrating feeding mechanism 10 at the feeding position, the metal ring 100 at the front end is pushed into the positioning groove 200 by the metal rings behind it. The upper end of the metal ring 100 protrudes from the upper end face of the rotating disk 22, the lower end of the upper ring 101 protrudes laterally from the lower ring 102 and abuts against the support table 202, and the lower end of the lower ring 102 protrudes from the lower end of the rotating disk 22, so that the metal rings 100 are positioned in the positioning groove 200. Multiple metal rings 100 are positioned by the multiple positioning grooves 200 of the feeding structure. When the metal ring 100 moves to the processing position during the rotation of the rotary disk 22 (driven by the rotary table 21), the inner wall of the cavity 1010 of the upper ring 101 can be tapped by the tapping equipment located outside the feeding structure. After the tapping is completed, the rotary disk 22 continues to rotate and drives the metal ring 100 to the unloading position. Since the upper ring 101 protrudes from the upper end of the rotary disk 22, the metal ring 100 can be pushed out of the positioning groove 200 by the sliding or rolling contact between the arc structure of the baffle arc surface 320 on the pusher plate 32 and the upper part of the upper ring 101, thereby completing the unloading of the metal ring 100 and completing the feeding of the metal ring 100 as a whole.

[0031] The positioning groove 200 in this invention is a through groove structure. Inside it, a support platform 202a is formed to support the lower end of the upper ring 101 protruding from the lower ring 102. The support platform 202a has two functions: supporting the lower end of the upper ring 101 and laterally limiting the lower ring 102. The portion of the positioning groove 200 located above the support platform 202a can also laterally limit the upper ring 101. Therefore, the support platform 202a, positioned in the middle of the positioning groove 200, can support the metal ring 100 and... By avoiding lateral restraints on the upper and lower parts of the metal ring 100, the stability of the metal ring 100 within the positioning groove 200 can be ensured. Furthermore, due to the through-slot design of the positioning groove 200, even if debris generated during tapping falls into the positioning groove 200, it can fall out, preventing accumulation and ensuring that it does not affect the position and state of the next metal ring 100 when fed into the positioning groove 200 by the vibratory feeding mechanism 10. This is beneficial to the accuracy and stability of the tapping process. In addition, the through-slot design of the positioning groove 200 is not affected by the length of the lower ring 102. The metal ring 100 is supported by the support platform 202 located within the positioning groove 200, making this positioning groove 200 structure suitable for metal rings with either a longer or shorter lower ring 102.

[0032] Preferably, in one embodiment of the present invention, the rotating disk 22 is in the form of an assembled structure, which includes an upper disk 21 and a lower disk 22 connected together. The outer diameters of the upper disk 21 and the lower disk 22 are equal. The upper disk 21 includes a first disk body 211 and first teeth 212 formed on the first disk body 211 at equal intervals. A first slot 201 is formed between an adjacent pair of first teeth 212. The lower disk 22 includes a second disk body 221 and second teeth 222 formed on the second disk body 221 at equal intervals. A second slot 202 is formed between an adjacent pair of second teeth 222. The first slot 201 and the second slot 202 are connected vertically to form a positioning groove 200. The portion of the vertical projection of the second teeth 222 located within the vertical projection of the first slot 201 forms a support platform 202a. In this embodiment, the first disc 211 abuts against the upper end of the second disc 221, the first tooth 212 abuts against the upper end of the second tooth 222, and the first slot 201 and the second slot 202 are connected. The upper disc 21 and the lower disc 22 are locked together by bolts. Both ends of the second tooth 222 protrude from the first tooth 212. Therefore, there is a protruding part on the second tooth 222 on each side of a positioning groove 200, which forms a support platform 202a. The end of the second tooth 222 is used to support the lower end of the upper ring 101. A pair of adjacent first teeth 212 and the side wall of the first disc 211 are used to position the upper ring 101, and a pair of adjacent second teeth 222 are used to position the lower ring 101. In this embodiment, the upper plate 21 and the lower plate 22 are assembled. Therefore, the first slot 201 and the second slot 202 can be machined on the upper plate 21 and the lower plate 22 respectively before assembly, thereby forming the first tooth 212 and the second tooth 222. This method makes it easy to machine the required grooves, and after assembly, the positioning groove 200 and the support platform 202a are formed. In addition, different positioning grooves 200 and support platforms 202a can be formed by combining upper plates 21 of different specifications (with different first slots 201) and lower plates 22 of different specifications (with different second slots 202), which has a wider range of applications and application methods.

[0033] Based on the above arrangement of the upper plate 21 and the lower plate 22, the support platform 202a is located on opposite sides of the positioning groove 200 and is close to the open end of the positioning groove 200, which can stably support the upper ring 101.

[0034] With the upper ring 101 positioned by the ends of a pair of first teeth 212 and the sidewall of the first disc 211, the lower ring 102 is limited only by the ends of a pair of second teeth 222, which can ensure the stability of the positioning of the metal ring 100 to a certain extent. However, in order to improve the stability of the positioning of the lower ring 102, the sidewall of the second disc 221 is provided with an auxiliary positioning platform 202b that extends into the second slot 202 and protrudes from the first slot 201, and there is a gap 2000 between the auxiliary positioning platform 202b and the support platform 202a. By setting the auxiliary positioning platform 202b, the structure formed by its sidewall and the ends of a pair of second teeth 222 can provide three-point positioning for the bottom ring 102, ensuring the stability of the positioning of the bottom ring 102. In addition, the auxiliary positioning platform 202b can further support the lower end of one side of the upper ring 101, effectively ensuring the stability of the upper ring 101, and improving and ensuring the stability of the metal ring 100 in the positioning groove 200. Furthermore, the existence of the gap 2000 can provide three-point support for the upper ring 101 and three-point limiting for the lower ring 102, allowing the positioning groove 200 to have a larger through path area, which can effectively prevent impurities from accumulating in the positioning groove 200.

[0035] Preferably, the open ends of the first slot 201 and the second slot 202 are provided with guide arc surfaces. For example, the open end of the first slot 201 is provided with a first guide arc surface 210, which can be used to allow the upper ring 101 to smoothly enter the first slot 201. The open end of the second slot 202 is provided with a second guide arc surface 220, which can be used to allow the lower ring 102 to smoothly enter the second slot 202.

[0036] like Figure 1 As shown, the vibratory feeding mechanism 10 includes a vibratory plate 11 and a linear vibration assembly 12 connected to the vibratory plate 11. The vibratory plate 11 is mounted on a first worktable 41, and the linear vibration assembly 12 is mounted on a second worktable 42. The linear vibration assembly 12 includes a linear vibration feeder and a feeding fixture mounted on the linear vibration feeder for connecting the vibratory plate 11 and the rotary table 22. The metal ring 100 can be conveyed within the feeding fixture. In addition, the rotary table 21 and the support 31 are both mounted on the second worktable 42.

[0037] Combination Figure 1 and Figure 5 As shown, a pair of waist-shaped holes 321 are provided parallel on the pusher plate 32. The pusher plate 32 is locked to the bracket 31 by bolts 322 passing through the waist-shaped holes 321. The position of the pusher plate 32 can be easily adjusted to adjust the position of the stop arc surface 320. It can be used for pushing and unloading metal rings 100 (upper ring 101) of different specifications.

[0038] Preferably, the feeding mechanism 30 further includes a material frame 33, which is located below the pusher plate 32 and can be used to receive the metal ring 100 after it has been tapped and fed out by the pusher plate 32.
