[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the present invention is described in detail with reference to schematic diagrams. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0035] Furthermore, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1

[0037] Reference Figures 1 to 7The present embodiment provides a sheet metal welding structure internal gear including a base wheel 100, the base wheel 100 includes two independent upper base wheels 101 and a lower base wheel 102, the upper base wheel 101 and the lower base wheel 102 are both hollow cylinders, the inner walls of the upper base wheel 101 and the lower base wheel 102 are both provided with a rotation groove 102a, the bottom of the outer wall of the upper base wheel 101 and the top of the outer wall of the lower base wheel 102 are both provided with a plurality of groups of first slide grooves 102b; a meshing member 200, the meshing member 200 includes a plurality of groups of tooth blocks 201, the tooth blocks 201 are arranged between the upper base wheel 101 and the lower base wheel 102; an adjusting member 300, the adjusting member 300 includes a first rotating plate 301 and a second rotating plate 302, the first rotating plate 301 is rotatably connected to the inside of the rotation groove 102a of the lower base wheel 102, and the second rotating plate 302 is rotatably connected to the inside of the upper base wheel 101.

[0038] Both ends of the tooth block 201 are fixedly connected with connecting rods 202, and the connecting rods 202 at both ends of the tooth block 201 are slidably connected inside the first sliding grooves 102b opened on the outer walls of the upper base wheel 101 and the lower base wheel 102 respectively; by sliding the connecting rods 202 inside the first sliding grooves 102b opened on the outer walls of the upper base wheel 101 and the lower base wheel 102, the tooth height of the gear can be adjusted, and the shape of the gear can also be changed to a spur external gear and an internal gear, thereby making the working scenario of a single gear more extensive.

[0039] A plurality of second slide grooves 302a are provided on the top of the outer wall of the second rotating plate 302, and the shape of the second slide grooves 302a is arc-shaped. The connecting rod 202 on the top of the tooth block 201 passes through the first slide groove 102b and the second slide groove 302a in sequence and is slidably connected with the inside thereof. The end of the connecting rod 202 on the top of the tooth block 201 is fixedly connected with the limit block 204, and the limit block 204 is arranged inside the upper base wheel 101 and between the top of the second rotating plate 302; since the connecting rod 202 of the tooth block 201 is slidably connected inside the second slide groove 302a of the second rotating plate 302 and the first slide groove 102b of the upper base wheel 101, the position of the tooth block 201 on the outer diameter of the upper base wheel 101 is determined by the rotation of the second rotating plate 302 inside the rotating groove 102a of the upper base wheel 101.

[0040] The connecting rod 202 at the bottom of the tooth block 201 is provided with teeth 203, and the top of the outer wall of the first rotating plate 301 is provided with a tooth groove 301a, and the tooth groove 301a is divided into an inner tooth diameter and an outer tooth diameter, and the teeth 203 are engaged with the inner tooth diameter or the outer tooth diameter of the first rotating plate 301; through the engagement of the teeth 203 with the lower base wheel 102 and the engagement of the limit block 204 with the outer wall of the second rotating plate 302, the upper base wheel 101, the lower base wheel 102 and the tooth block 201 are in an inseparable connection state, and because the teeth 203 are engaged with the inner tooth diameter or the outer tooth diameter of the tooth groove 301a, the state of the tooth block 201 is further limited, so that it cannot rotate freely when the first rotating plate 301 is in a fixed state.

[0041] A first tooth tip 201a and a second tooth tip 201b are respectively provided at both ends of the tooth block 201, and the tapers of the first tooth tip 201a and the second tooth tip 201b are different; when dealing with different working scenarios, the tooth block 201 can be rotated to select the first tooth tip 201a or the second tooth tip 201b as the working tooth. Since the tapers of the first tooth tip 201a and the second tooth tip 201b are different, the selected tooth thickness is different, which makes the gear more widely applicable.

[0042] The outer walls of the upper base wheel 101 and the lower base wheel 102 are both provided with pin grooves 102c, and the upper base wheel 101 and the second rotating plate 302 as well as the lower base wheel 102 and the first rotating plate 301 are all fixed by bolts; the purpose is to fix the first rotating plate 301 and the first rotating plate 301 by bolts so as to limit the tooth block 201 and prevent it from rotating and sliding.

[0043] The first slide groove 102b and the second slide groove 302a are both distributed in a circular array on the outer wall of the upper base wheel 101 and the second rotating plate 302, and the first slide groove 102b and the second slide groove 302a correspond to each other; through this structure, the gear can adjust the position of all the tooth blocks 201 by rotating the second rotating plate 302 in this embodiment.

[0044] Example 2

[0045] Reference Figures 1 to 7 , which is the second embodiment of the invention. Based on the previous embodiment, this embodiment provides an implementation method of an internal gear of a sheet metal welding structure. The difference from the previous embodiment is that the upper base wheel 101 is internally connected to rotate in an overlapping manner with at least one group of second rotating plates 302, and the circumferential distribution angle of the second sliding groove 302a opened on the outer wall of each group of second rotating plates 302 is less than 360°, and the sum of the circumferential distribution angles of the second sliding grooves 302a opened by several groups 303 is 360°; the positions of different teeth in the gear are regulated by different groups of second rotating plates 302, so that the tooth block 201 is completely received between the upper base wheel 101 and the lower base wheel 102 through the regulation of the first rotating plate 301 of the second rotating plate 302, so that a part of the gear teeth do not participate in the work, so that the circumferential pitch of the gear is adaptively changed.

[0046] Furthermore, by using a plurality of different sets of second rotating plates 302 to control the gear blocks 201 of any number and position, the size of the gear blocks 201 is configured to form a half gear through the above-mentioned operation mode, so that the gear blocks can be operated in an intermittent mechanism.

[0055] During the process of completing the gear assembly in S100, the following conditions are met: the length of the tooth block 201 is smaller than the difference between the outer diameter and the inner diameter of the upper base wheel 101; this size structure allows the tooth block 201 to be fixed without protruding from the inner diameter and the outer diameter of the upper base wheel 101.
