[0002] like Figure 1 The rotary table 100 shown includes a central portion 101 and symmetrically located support portions 102 on both sides of the central portion 101. In modern industrial production and machinery manufacturing, rotary tables are a common type of mechanical equipment widely used in various four-axis and five-axis CNC machine tools. They enable precise rotary motion, meet different process and operational requirements, and allow for multi-face machining in a single setup. Their precision is crucial for ensuring product quality, improving production efficiency, and achieving high-precision process operations.

[0003] Currently, some simple fixing devices cannot provide sufficient stability and rigidity, resulting in a loss of accuracy during the assembly and testing of the turntable. Furthermore, existing turntable assembly tooling suffers from poor versatility and inconvenient accuracy testing, which is detrimental to ensuring turntable accuracy and improving assembly efficiency.

[0004] To address this, the inventors developed a novel turntable assembly and its precision testing device. This device involves installing a central mounting frame, a support mounting platform, guide rails, and a marble testing straightedge on a general assembly platform. The mounting platform slides along the guide rails to adjust the installation position, accommodating various turntable specifications. During the development and design of this turntable assembly and its precision testing device, the overall size and weight of the turntable, along with the central mounting frame, support mounting platform, and guide rails, made the specific structure of the general assembly platform particularly important. The design focus was on achieving both weight reduction and load-bearing capacity, as well as the rational and compact arrangement of the aforementioned components on the platform. Utility Model Content

[0005] To at least partially solve the above-mentioned technical problems, this utility model proposes a new type of assembly platform suitable for turntables.

[0006] This utility model proposes an assembly platform suitable for turntables, comprising a cuboid platform body. The platform body has a bottom cavity extending upward from the bottom. The portion between the top wall of the bottom cavity and the top surface of the platform body constitutes the supporting top of the platform body. The portions between the side walls of the bottom cavity and the corresponding side surfaces of the platform body constitute the side surfaces of the platform body. A partition wall extends downward from the top wall of the bottom cavity to divide the bottom cavity into multiple sub-cavities. Each sub-cavity has a central ring wall. The ring wall is connected to the corresponding partition wall and the side surfaces of the bottom cavity by connecting wall plates. A turntable center mounting position is constructed at the center position of the supporting top. Turntable support mounting positions are symmetrically arranged on both sides of the turntable center mounting position of the supporting top. A detection ruler mounting position is constructed near the rear side of the supporting top.

[0007] Preferably, the central mounting position of the turntable includes a pair of first mounting platforms arranged on the left and a pair of second mounting platforms arranged on the right. The pair of first mounting platforms can be used for mounting on the first mounting frame, and the pair of second mounting platforms can be used for mounting on the second mounting frame.

[0008] Preferably, the turntable support mounting position includes guide rail assemblies respectively arranged at both ends near the top of the support, and each guide rail assembly is equipped with at least one slider, which is connected to the turntable support mounting platform.

[0009] Preferably, the guide rail assembly includes two guide rails arranged in pairs, each of which is equipped with at least one slider.

[0010] Preferably, the testing straightedge mounting position includes two mounting platforms located near the rear side of the top of the support, and the two mounting platforms are used to install and connect the testing straightedge support base.

[0011] Preferably, each of the partition walls is provided with through holes, at least some of the connecting wall panels are provided with through holes, at least some of the bottom cavity side panels are provided with through holes, and the opening height of the through holes is consistent.

[0012] Preferably, the bottom of the partition wall extends into inner expansion edges on both sides, and the bottom of the bottom cavity side extends into outer expansion edges. The intersection of the inner expansion edges and the outer expansion edges continues to extend downward into a bottom mounting frame edge. The intersection of the longitudinal outer expansion edges and the transverse outer expansion edges also continues to extend downward into a bottom mounting frame edge.

[0013] Preferably, the side of the platform body is provided with an operating cavity located above the bottom mounting frame edge at each bottom mounting frame edge, and the operating cavity is recessed inward relative to the side of the platform body to connect with the adjacent connecting wall panel and / or partition wall.

[0014] Preferably, the bottom mounting frame edge and the operating cavity are configured to form a mounting base plate, and a lifting adjustment mechanism is mounted and connected on the mounting base plate. The lifting adjustment mechanism includes an adjusting foot pad and an adjusting bolt installed in the adjusting foot pad. The adjusting bolt passes through the mounting base plate and is located in the operating cavity.

[0015] Preferably, the top of the support is also symmetrically provided with abutting and limiting blocks on the front and rear sides of the guide rail assembly, and the abutting and limiting blocks are symmetrically arranged to fix the turntable support mounting platform.

[0016] Beneficial effects:

[0017] The assembly platform of this application, by constructing a turntable center mounting position, a turntable support mounting position, and a testing straightedge mounting position on the top of the load-bearing structure, allows for the simultaneous installation of the turntable and the testing straightedge on the assembly platform.

[0018] The assembly platform of this application can significantly reduce the weight of the assembly platform by setting the bottom cavity. At the same time, because the overall structure is a rectangular platform body, it has the load-bearing strength and can match the installation weight of the turntable and the inspection flat ruler.

[0019] The assembly platform of this application compensates for the reduced strength of the assembly platform due to the bottom cavity by setting up partition walls, circular walls and connecting wall panels, and at the same time, the layout is regular and easy to cast.

[0028] 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.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0032] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0033] refer to Figures 1-4 This utility model proposes an assembly platform suitable for turntables, including a rectangular platform body 1. The platform body 1 has a bottom cavity 2 extending upward from the bottom. The portion between the top wall of the bottom cavity 2 and the top surface of the platform body 1 constitutes the load-bearing top 3 of the platform body 1. The portions between the four side walls of the bottom cavity 2 and the corresponding four side surfaces of the platform body 1 constitute the four side portions 4 of the platform body 1. Furthermore, regarding the internal structure of the bottom cavity 2, in this embodiment, a partition wall 5 extends downward from the top wall of the bottom cavity 2 to divide the bottom cavity 2 into multiple sub-cavities 6. Each sub-cavity 6 has a centrally located circular wall 7. The circular wall 7 is connected to the corresponding partition wall 5 and the side portions of the bottom cavity 2 via connecting wall plates 8. As can be seen, with the bottom cavity 2, the assembly platform is constructed into a cuboid shape that supports the top 3 and the surrounding sides 4, which can significantly reduce weight. At the same time, the bottom cavity 2 also constructs structural components such as partition walls 5, circular walls 7, and connecting wall panels 8 to prevent the bottom cavity 2 from forming a large cavity that would weaken its load-bearing capacity. Furthermore, the various components can be arranged in a regular manner after being combined, and can be integrally cast.

[0034] In this embodiment, three cavities 6 are arranged close together along the length of the bottom cavity 2. The internal structure of each cavity 6 is basically consistent, very regular, and easy to be integrally cast.

[0035] To enable the installation of the turntable 100 and the inspection ruler 200, the top support 3 is configured with a turntable center mounting position at the middle position, the top support 3 is symmetrically configured with turntable support mounting positions on both sides of the turntable center mounting position, and the top support 3 is configured with an inspection ruler mounting position near the rear side.

[0036] Specifically, in this embodiment, the central mounting position of the turntable includes a pair of first mounting platforms 9 arranged on the left and a pair of second mounting platforms 10 arranged on the right. The paired first mounting platforms 9 can be used to mount the first mounting bracket 11, and the paired second mounting platforms 10 can be used to mount the second mounting bracket 12. It should be noted that each pair of mounting platforms includes two mounting platforms arranged symmetrically front to back, and each mounting platform has a mounting hole (unmarked) for mounting the end of the corresponding mounting bracket. After the first mounting bracket 11 and the second mounting bracket 12 are installed on the corresponding mounting platforms, the two mounting brackets are used to support the left and right sides of the bottom of the central part 101 of the turntable.

[0037] The turntable support mounting position includes guide rail assemblies respectively arranged at both ends near the top 3 of the bearing. Each guide rail assembly is equipped with at least one slider 13, which is connected to the turntable support mounting platform 14. After the turntable support mounting platform 14 is installed and connected to the slider 13, the turntable support 102 can be installed on the turntable support mounting platform 14. Considering that the turntable support mounting platform 14 and the turntable support 102 have a certain weight, the guide rail assembly includes two guide rails 16 arranged in pairs, each of which is equipped with at least one slider 13. The arrangement of the two guide rails 16 can distribute the weight and maintain the stability of operation. It should be noted that, since turntables come in different sizes, the turntable support mounting platform 14 can slide along the guide rail 16 to fit the turntable installation. Therefore, after the turntable support mounting platform 14 is adjusted to the correct position, it needs to be fixed. In this embodiment, the bearing top 3 is also symmetrically provided with abutting and limiting blocks 27 on the front and rear sides of the guide rail assembly. The abutting and limiting blocks 27 are symmetrically arranged to fix the turntable support mounting platform 14.

[0038] The mounting position for the testing straightedge includes two mounting platforms 17 located near the rear side of the top of the support 3. These platforms 17 are used to mount and connect corresponding testing straightedge support seats 18. After the testing straightedge support seats 18 are mounted on the corresponding mounting platforms 17, the testing straightedge 200 can be mounted on the testing straightedge support seats 18. It should be noted that the two mounting platforms 17 are arranged along the length of the top of the support 3, and each mounting platform 17 has mounting holes (unmarked), with one testing straightedge support seat 18 mounted on each platform 17.

[0039] The assembly platform described above allows the turntable 100 to be installed with its center 101 positioned as far forward as possible from the top of the load-bearing platform 3, and the turntable support 102 positioned at both ends as far forward as possible from the top of the load-bearing platform 3. Ultimately, this allows the turntable 100 to be installed as far forward as possible from the top of the load-bearing platform 3, thus reserving a rear installation position for the inspection ruler 200. The overall installation layout satisfies the reasonable installation requirements of the turntable 100 and the inspection platform 200.

[0040] For the final assembly platform, based on weight reduction and material saving in the bottom cavity 2 and each sub-cavity 6, through holes 19 are provided on all partition walls 5, and at least some of the connecting wall panels 8 also have through holes 19. At least some of the side portions 4 of the bottom cavity 2 also have through holes 19, and all through holes 19 are positioned at the same height. With the further arrangement of through holes 19, the effects on weight reduction and material saving are more significant, and the uniformly positioned through holes 19 maintain the regularity of the internal structure of the final assembly platform.

[0041] To facilitate the adjustment of the height of the assembly platform and reduce the machining area at the bottom (because the bottom of the assembly platform needs to maintain a consistent height and be flat, and since the assembly platform is a casting, the bottom generally needs to be machined to produce a consistent and flat bottom surface), the bottom of the partition wall 5 extends into inner extension edges 20 on both sides, and the bottom of the side portion 4 of the bottom cavity 2 extends into outer extension edges 21. The intersection of the inner extension edges 20 and the outer extension edges 21 continues to extend downward into bottom mounting frame edges 22. The intersection of the longitudinal outer extension edge (along the width direction of the assembly platform) and the transverse outer extension edge (along the length direction of the assembly platform) of the outer extension edge 21 also continues to extend downward into bottom mounting frame edges 22. The assembly platform forms a total of 8 bottom mounting frame edges 22 at the bottom. In this way, the bottom of the bottom mounting frame edges 22 can replace the bottom of the assembly platform, and the total area of ​​the bottom surface of the mounting frame edges 22 is small, reducing the machining area.

[0042] Meanwhile, the side portion 4 of the platform body 1 is provided with an operating cavity 23 located above each bottom mounting frame edge 22. The operating cavity 23 is recessed inward relative to the side portion of the platform body 1 to connect with the adjacent connecting wall plate 8 and / or partition wall 5. It should be noted that the operating cavity 23 is recessed inward relative to the side portion of the platform body 1 to connect with the adjacent connecting wall plate 8 and / or partition wall 5. It can be understood that it connects with the connecting wall plate 8 when it is present, and connects with the partition wall 5 when it is present. That is, the connection is based on the actual presence of the partition wall 5. The bottom mounting frame edge 22 and the operating cavity 23 are configured to form a mounting base plate 24. A lifting adjustment mechanism is mounted and connected on the mounting base plate 24. The lifting adjustment mechanism includes an adjusting foot pad 25 and an adjusting bolt 26 installed in the adjusting foot pad 25. The adjusting bolt 26 passes through the mounting base plate 24 and is located in the operating cavity 23. With the operating cavity 23 set up in this way, workers can operate within the operating cavity 23. The assembly platform can be made parallel to the ground by adjusting the adjusting bolt 26, thereby improving the stability of the tooling.

[0043] The assembly platform of this application can stably fix the turntable 100, reducing errors caused by the shaking or displacement of the turntable 100 during the testing process, thereby significantly improving the accuracy and reliability of the precision testing results; it provides consistent fixing and testing conditions, so that similar results can be obtained each time the same turntable 100 is precision tested, ensuring the repeatability and consistency of the test.

[0044] The assembly platform of this application is made entirely of castings. It is ingeniously designed in terms of load-bearing capacity, weight reduction, and material saving. It takes into account the purpose of weight reduction and material saving while achieving sufficient load-bearing capacity. More importantly, it is equipped with a height fine-tuning mechanism for the assembly platform, such as a lifting adjustment mechanism, which can make fine adjustments to the local height of the assembly platform to keep the whole parallel to the ground. In the assembly platform of this application, there is no need to set up an additional operating space. The operating cavity 23 is directly constructed on the platform body 1, and the local height of the assembly platform can be finely adjusted in the operating cavity 23.

[0045] The assembly platform of this application has multiple installation positions on the top 3 of the support, which can simultaneously install the turntable 100 and the inspection flat ruler 200, thus satisfying both installation and various inspection requirements.

[0046] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
