Traditional motors often use a built-in encoder or magnetic scale for position encoding, resulting in wasted range, insufficient accuracy, and high costs. Furthermore, during the assembly, installation, operation, adjustment, or maintenance of the alignment and correction platform, vibration, bumps, and connections are prone to occur, reducing the accuracy of the angle turntable's built-in encoder or magnetic scale and making repair and adjustment difficult.

[0013] In some embodiments, the second positioning member includes a first limiting portion and a second limiting portion, the first limiting portion and the second limiting portion are correspondingly arranged on both sides of the second positioning member, and a limiting groove is formed between the first limiting portion and the second limiting portion, and the limiting groove is used to limit the tangential displacement of the encoder relative to the motor.

[0028] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

If the specific posture changes, the directional indication will also change accordingly.
[0030] It should also be understood that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element through an intervening element.
[0031] The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. For example, the terms "first," "second," and so on are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, the term "first" or "second" may explicitly or implicitly include at least one of the features.
[0032] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.
[0033] See also Figure 1 and Figure 2 The embodiment of the present application provides an angle turntable 100 , which at least includes a base 10 , a direct drive module 20 , a positioning assembly 30 and an encoder 40 .
[0034] Exemplarily, the direct drive module 20 may include a housing 21 , a scale 22 and a motor.
[0035] The motor may be disposed in the housing 21 , which is rotatably connected to the base 10 via the motor. The scale 22 is snugly disposed on the circumference of the housing 21 , and the motor drives the housing 21 to rotate relative to the base 10 .
[0036] Furthermore, the motor includes a disc motor or a torque motor.
[0037] It can be understood that the motor can drive the shell 21 to rotate relative to the base 10, and the parts or loads to be aligned and corrected can be connected to the shell 21, so that they rotate with the drive of the motor, thereby realizing the alignment and correction function of the angle turntable 100.
[0038] Furthermore, the positioning assembly 30 may include a first positioning member 31 and a second positioning member 32 .
[0039] The first positioning member 31 may be connected to the base 10 , and the second positioning member 32 may be connected to the first positioning member 31 .
[0040] It is understandable that the positioning assembly 30 may include two independent components, a first positioning member 31 and a second positioning member 32, or may be an integral positioning member formed in one piece, for fixing the encoder 40. The first positioning member 31 and the second positioning member 32 may be detachably connected to each other.
[0041] Furthermore, the encoder 40 may be disposed on the second positioning member 32 .
[0042] The encoder 40 includes a reading head, which corresponds to the scale 22 and can detect the scale of the scale 22 .
[0043] Exemplarily, the scale 22 may include a magnetic scale, and the reading head may include a magnetic reading head.
[0044] Exemplarily, the scale 22 may also include a grating scale, and the reading head may include a grating reading head.
[0045] Furthermore, the magnetic scale may include a magnetic scale obtained by arc magnetization or a magnetic scale obtained by linear magnetization and bending.
[0046] It is understandable that the traditional magnetic scale obtained by linear magnetization and bending will cause the positioning accuracy of the scale 22 to decrease due to operations such as bending. The magnetic scale obtained by arc magnetization avoids the influence of operations such as bending on the internal magnetic signal and magnetic scale of the magnetic scale by first bending and then performing arc magnetization based on the arc state to generate a scale. The magnetization parameters of the magnetic scale can be set according to actual accuracy requirements and range requirements, thereby improving the positioning accuracy, scalability and maintainability of the angle turntable 100.
[0047] In some embodiments, the angle turntable 100 is provided with a limit design to prevent the motor drive housing 21 from rotating beyond the range or stroke relative to the base 10, thereby causing mechanical failure, reduced accuracy or component damage.
[0048] Exemplarily, the direct drive module 20 may further include a built-in mechanical limiter.
[0049] In some embodiments, the first positioning member 31 is detachably connected to the base 10; and / or the first positioning member 31 is detachably connected to the second positioning member 32.
[0050] Understandably, in industrial and commercial applications, whether installing and commissioning the angle turntable 100 and its alignment and correction platform, or operating it daily, improper operation, bumps, vibration, and other factors can negatively impact the accuracy of the angle turntable 100. Traditional solutions with built-in scales 22 often require disassembly of the housing 21 for repair or component replacement, which is time-consuming and labor-intensive, and may also cause other bumps. By snugly positioning the scale 22 against the circumference of the housing 21 and employing a design in which the first locating member 31 and the base 10, as well as the first and second locating members 31 and 32, installation, assembly, commissioning, and maintenance are facilitated for both users and manufacturers, improving product reliability.
[0051] In some embodiments, see Figure 3 ,like Figure 3 As shown, the base 10 includes a peripheral opening 11, and the first positioning member 31 includes a positioning shoulder 311. The first positioning member 31 is embedded and connected to the base 10 through the peripheral opening 11. The positioning shoulder 311 corresponds to the peripheral opening 11 and is used to limit the distance at which the first positioning member 31 is embedded in the base 10.
[0052] It can be understood that by limiting the distance at which the first positioning member 31 is embedded in the base 10, the distance between the encoder 40 and the scale 22 is limited, thereby improving the product accuracy consistency of the angle turntable 100 in batch and large-scale production, ensuring reading accuracy, and improving product reliability.
[0053] Furthermore, the positioning shoulder 311 may include a first shoulder 311a and a second shoulder 311b. The first shoulder 311a and the second shoulder 311b may be correspondingly arranged on both sides of the first positioning member 31. A positioning area is formed between the first shoulder 311a and the second shoulder 311b, and the second positioning member 32 is detachably connected to the first positioning member 31 through the positioning area.
[0054] It can be understood that by forming a positioning area between the first shoulder 311a and the second shoulder 311b, the position of the second positioning member 32 relative to the first positioning member 31 can be limited, thereby limiting the tangential displacement of the encoder 40 relative to the motor, ensuring the product production and assembly accuracy, and improving product reliability.
[0055] Further, in some embodiments, see Figure 4 ,like Figure 4 As shown, the second positioning member 32 may include a first limiting portion 32a and a second limiting portion 32b. The first limiting portion 32a and the second limiting portion 32b may be correspondingly arranged on both sides of the second positioning member 32. A limiting groove is formed between the first limiting portion 32a and the second limiting portion 32b. The limiting groove is used to limit the tangential displacement of the encoder 40 relative to the motor.
[0056] The embodiments of the present application further provide an alignment and deviation correction platform, which may include an angle turntable 100 as in any embodiment of the present application.
[0057] Those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples without mutual contradiction.
[0058] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present application, and such modifications or substitutions should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
