[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Combine the following Figure 1-Figure 4 The limiting structure of the turntable of the utility model is described.

[0029] See also Figure 1 and Figure 4 As shown, the limiting structure of the turntable according to the embodiment of the utility model includes a seat body 101, a shell 103, a core body 104 and a buffer member 105.

[0030] Specifically, the shell 103 is connected to the base 101. For example, the shell 103 can be welded to the base 101. The shell 103 can be deformed. For example, the shell 103 can be an aluminum alloy shell structure. The outer wall of the shell 103 is suitable for abutting against the moving part to limit the moving part. The moving part can be a movable structure of a mechanical device such as a turntable and a motor. For example, the moving part can be a spatial pointing mirror turntable, a Kude turntable, or a rotating part of a periscope turntable. The core 104 is arranged in the shell 103. The core 104 can be connected to the base 101. For example, one end of the core 104 can be welded to the base 101; or, the core 104 and the base are integrally formed.

[0031] The seat body 101 can provide a mounting position for the core body 104 and the shell 103, and the limiting structure of the turntable and other components can be fixedly connected through the seat body 101. Figure 1 and Figure 2 As shown, in some embodiments, the base 101 protrudes from the base 101 in the horizontal direction, and a plurality of connection holes 102 are provided on the base 101. The connection holes 102 are through holes, and the base 101 is connected to other components by screws.

[0032] like Figure 3 and Figure 4As shown, the core 104 is located in the shell 103, the core 104 is spaced apart from the shell 103, and the buffer 105 is filled between the shell 103 and the core 104, that is, the buffer 105 is in contact with the peripheral wall of the core 104 and the inner peripheral wall of the shell 103, the core 104 supports the buffer 105, the buffer 105 is deformable and elastic, and the buffer 105 is used to buffer the impact force between the moving parts and the shell 103. In this way, when the moving parts exceed the boundary or lose control during operation, the moving parts collide with the shell 103, the shell 103 is deformed to a certain extent, and the buffer 105 is squeezed at the same time, and the buffer 105 is elastically deformed to absorb the collision energy, thereby reducing the impact on the turntable, motor and other equipment. In addition, the buffer 105 is disposed in the housing 103, and the buffer 105 does not directly contact the moving parts, so that when the moving parts collide with the limiting structure of the turntable, the buffer 105 is less worn, and the material will not peel off due to extrusion or force, thereby extending the service life of the limiting structure of the turntable. In some embodiments, the buffer 105 can be a silicone member. During the manufacturing process, the buffer 105 can be formed by injecting silicone rubber or other fillers into the gap between the core 104 and the housing 103, filling it evenly, and waiting for the filler to cure for more than 48 hours.

[0033] According to the limiting structure of the turntable in the embodiment of the utility model, the impact of the moving parts is absorbed by the buffer 105, so as to reduce the influence of the impact of the moving parts when the moving parts are limited on the overall equipment; the buffer 105 is separated from the moving parts by the shell 103, so as to avoid the moving parts directly contacting the buffer 105, so that when the moving parts collide with the limiting structure of the turntable, the buffer 105 is less worn, so as to avoid the material peeling of the buffer 105 due to extrusion or force, thereby extending the service life of the limiting structure of the turntable.

[0034] See also Figure 4 As shown, according to some embodiments of the utility model, the peripheral wall of the core 104 is spaced apart from the inner wall of the shell 103, and the four sides of the core 104 are spaced apart from the inner peripheral wall of the shell 103, and the buffer 105 is annular, so that the buffer 105 is in contact with the inner peripheral wall of the shell 103 to buffer the impact on the peripheral wall of the shell 103, and the volume of the buffer 105 is made as large as possible within a limited space to reduce the deformation of the buffer 105 when absorbing collision energy.

[0035] According to some embodiments of the utility model, the height of the buffer 105 is greater than the height of the core 104, so that the top of the buffer 105 is spaced apart from the inner top wall of the shell 103, and there is a certain space between the top of the buffer 105 and the inner top wall of the shell 103 to provide sufficient space for the buffer 105 to deform. In some embodiments, by filling filler between the core 104 and the shell 103, the filler is solidified to form the buffer 105, and a fixing column can be set on the seat at a position between the core 104 and the shell 103. During the filling process, the filler wraps the fixing column, so that after the filler is solidified to form the buffer 105, the fixing column is embedded in the buffer 105 to fix the position of the buffer 105. The thickness of the buffer 105 is 0.8mm-1mm. For example, the thickness of the buffer 105 can be 0.8mm, 0.9mm or 10mm. The size of the limit structure of the turntable is reduced while ensuring that the buffer 105 can provide sufficient damping.

[0036] like Figure 1 As shown, according to some embodiments of the utility model, the housing 103 includes a main body 106 and a cover 107 connected to each other, the main body 106 is connected to the seat 101, and the main body 106 is suitable for abutting against the moving parts, and the core 104, the main body 106 and the seat 101 are integrally formed to facilitate filling of fillers. The core 104 and the main body 106 can be integrally formed with the seat 101 to save process flow and improve production efficiency. During the assembly process, the filler is filled between the core 104 and the housing 103, and the height of the filler is less than the height of the main body 106. After the filler is solidified to form the buffer 105, the cover 107 is welded to the main body 106 to complete the assembly.

[0037] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the base 101 is provided with a plurality of connection holes 102, and the base 101 can be fixed to the device through the connection holes 102 and screws, so that the moving part abuts against the outer wall of the shell 103. The plurality of connection holes 102 are spaced apart along the circumferential direction of the shell 103 to fix the limit structure of the turntable from multiple directions. In some embodiments, the shell 103 includes a first side wall and a second side wall opposite to each other, and the first side wall and the second side wall are suitable for abutting against the moving part, such as Figure 1 and Figure 4 In the example, the shell 103 is a cube, and the cross-section of the shell 103 is a rectangle, wherein the side walls corresponding to the two longer sides are respectively the first side wall and the second side wall, which abut against the moving part to increase the contact area between the shell 103 and the moving part and improve the stability of the moving part.

[0038] like Figure 1As shown, the connection holes 102 are symmetrically distributed along the direction of the first side wall and the second side wall, that is, part of the connection holes 102 are located on the side where the first side wall is located, and the other part is located on the side where the second side wall is located. Since the collision of the moving parts on the shell 103 is mainly along the direction where the first side wall and the second side wall are located, arranging the connection holes 102 in this direction can reduce the number of connection holes 102 that need to be opened, and reduce the damage to the structure of the seat body 101. Figure 1 As shown, the core 104 and the shell 103 can both be arranged in the middle of the base 101, so that when the moving part collides with the shell 103, the force on the base 101 is more uniform.

[0039] According to the turntable of the embodiment of the utility model, it includes a moving part and a limiting structure of the turntable, the moving part is suitable for driving the workpiece to rotate; the shell abuts against the moving part. In this way, when the moving part exceeds the boundary or loses control during operation, the moving part collides with the shell 103, the shell 103 undergoes a certain deformation, and at the same time squeezes the buffer 105, the buffer 105 undergoes elastic deformation to absorb the collision energy, thereby reducing the impact on the turntable, motor and other equipment. In addition, the buffer 105 is arranged in the shell 103, and the buffer 105 does not directly contact the moving part, so that when the moving part collides with the limiting structure of the turntable, the buffer 105 is less worn, and there will be no material peeling due to squeezing or force, thereby extending the service life of the limiting structure of the turntable.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
