[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0004] However, current nut tapping equipment lacks a mechanism for positioning nuts of different sizes during the tapping process. This means that different positioning plates need to be replaced or the positioning needs to be manually adjusted when processing nuts of different sizes, which is time-consuming and labor-intensive, and reduces the production efficiency of nut tapping.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a nut tapping device, which solves the problem of reduced production efficiency caused by the time-consuming and labor-intensive process of tapping nuts of different sizes by changing different positioning plates or making manual adjustments.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

Nut positioning grooves are evenly distributed axially on the outer side of the nut positioning plate. The nut positioning grooves are divided into multiple layers and their size decreases from top to bottom.

[0009] The inner dimensions of the positioning arc plate are the same as the inner dimensions of the nut positioning groove. A column located on the other side of the nut positioning plate is fixedly installed on the other side of the positioning arc plate. A pre-storage groove is opened inside the column, and the bottom of the pre-storage groove is inclined. Protective plates are fixedly installed at the front and rear ends of the discharge port on one side of the bottom of the pre-storage groove.

[0010] Preferably, the top of the nut tapping base is provided with an annular groove, and a support ring fixed to the bottom of the nut positioning plate is slidably installed inside the annular groove.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a nut tapping device.

[0025] Please see Figures 1-6 A nut tapping device includes a nut tapping base 1, a servo motor 101 fixedly installed inside the nut tapping base 1, and a positioning arc plate 2 fixedly installed at the top rear end of the nut tapping base 1. A nut positioning plate 102 fixedly connected to the output end of the servo motor 101 is rotatably installed on the top of the nut tapping base 1. Nut positioning grooves 103 are evenly distributed on the outer side of the nut positioning plate 102 in an axial manner. The nut positioning grooves 103 are divided into multiple layers and the size decreases from top to bottom.

[0026] The inner dimensions of the positioning arc plate 2 are the same as the inner dimensions of the nut positioning groove 103. A column 201 located on the other side of the nut positioning plate 102 is fixedly installed on the other side of the positioning arc plate 2. A pre-storage groove 202 is opened inside the column 201, and the bottom of the pre-storage groove 202 is inclined. A protective plate 203 is fixedly installed at the front and rear ends of the discharge port on one side of the bottom of the pre-storage groove 202.

[0027] With the above-described structural configuration, this nut tapping device pre-stores the nut inside the pre-storage slot 202. Then, the servo motor 101 drives the nut positioning plate 102 to rotate, causing the nut positioning slot 103 to rotate to one side of the bottom of the pre-storage slot 202. Since the nut positioning slot 103 has multiple layers of different sizes, with the top layer being the largest, the bottom of the pre-storage slot 202 is an inclined surface, and the rear end of the nut positioning plate 102 is surrounded by a positioning arc plate 2, nuts of different sizes can be automatically positioned to the center of the nut positioning slot 103 after sliding into the nut positioning slot 103 at the bottom of the pre-storage slot 202. This facilitates automatic positioning and tapping of nuts of different sizes, avoiding the time-consuming and labor-intensive process of changing different positioning plates or manual adjustment during tapping of nuts of different sizes, which leads to reduced production efficiency.

[0028] Furthermore, the top of the nut tapping base 1 is provided with an annular groove 104, and a support ring 105 fixed to the bottom of the nut positioning plate 102 is slidably installed inside the annular groove 104. When the nut positioning plate 102 rotates on top of the nut tapping base 1, the support ring 105 rotates inside the annular groove 104 to support the nut positioning plate 102, making the rotation of the nut positioning plate 102 more stable.

[0029] Furthermore, a support frame 106 is fixedly installed on one side of the top of the nut tapping base 1, and a telescopic rod 107 is fixedly installed on the bottom of the other side of the support frame 106. The bottom of the telescopic rod 107 is fixedly connected to the nut tapping equipment body 108. When the nut is positioned to the center position inside the nut positioning groove 103, the servo motor 101 drives the positioned nut to rotate to the bottom of the nut tapping equipment body 108. The output end of the telescopic rod 107 drives the nut tapping equipment body 108 to extend downward, so that the nut tapping equipment body 108 performs tapping operations on the nut.

[0030] Furthermore, the protective plate 203 has a sliding groove 204 inside, a sliding rod 205 is slidably installed inside the sliding groove 204, a baffle 206 is fixedly connected between the sliding rods 205, the protective plate 203 has a through groove 207 located on one side of the sliding groove 204, a triangular top plate 208 is fixedly installed on the top of the nut positioning plate 102 in an axially evenly distributed manner, and a fixing rod 209 is fixedly installed on one side of the rear sliding rod 205. In this mechanism, the baffle 206 blocks the opening at the bottom of the pre-storage slot 202, preventing multiple nuts from sliding out to the top of the nut positioning plate 102 and causing confusion. When the nut positioning slot 103 moves to the discharge port of the pre-storage slot 202, the triangular top plate 208 passes through the through slot 207. Since the top of the triangular top plate 208 is a triangular inclined surface, the fixing rod 209 moves upward along the inclined surface of the top of the triangular top plate 208, thereby driving the sliding rod 205 to slide upward inside the sliding groove 204, causing the baffle 206 to move upward between the protective plates 203. At this time, one nut inside the pre-storage slot 202 falls into the nut positioning slot 103. Through the above mechanism, the nuts inside the pre-storage slot 202 can slide into the nut positioning slot 103 one by one for positioning.

[0031] Furthermore, a cover 3 is screwed onto the top of the pre-storage tank 202, and a positioning rod 301 extending into the interior of the pre-storage tank 202 is fixedly installed at the bottom of the cover 3. When the nut is placed inside the pre-storage tank 202 for pre-storage, the cover 3 is then placed on top of the pre-storage tank 202, causing the positioning rod 301 to penetrate the inner hole of the nut for positioning, thus allowing the nut to slide more stably out of the top outlet of the pre-storage tank 202.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
