[0027] 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.

[0028] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0031] This utility model proposes a device for turntable assembly and precision testing. The device has a first mounting platform 1 and a second mounting platform 2 with adjustable positions. The first mounting platform 1 and the second mounting platform 2 move and cooperate to support and fix turntable support parts 11 of different specifications and sizes. The first mounting frame 3 and the second mounting frame 4 cooperate to be used for the installation of the turntable center part 10. Therefore, it can be applied to turntables of various specifications and models, and has strong versatility and compatibility.

[0032] Specifically, in one embodiment of the utility model, such as Figure 1-7 As shown, the device for turntable assembly and its precision inspection includes an assembly platform 100 and a turntable center mounting frame 200, a turntable support mounting platform 300, and a testing straightedge 400, all located on top of the assembly platform 100. The turntable center mounting frame 200 includes a first mounting frame 3 and a second mounting frame 4, which are respectively arranged along the width direction of the assembly platform 100 and symmetrically spaced at the middle position of the top of the assembly platform 100. The turntable support mounting platform 300 includes a first mounting platform 1 and a second mounting platform 2, which are respectively arranged along the width direction of the assembly platform 100 and symmetrically located on both sides of the turntable center mounting frame 200. The top of the assembly platform 100 is provided with slide rails 500 at the first mounting platform 1 and the second mounting platform 2, respectively, and the first mounting platform 1 and the second mounting platform 2 are slidably mounted on the corresponding slide rails 500. The testing ruler 400 is positioned along the length of the top of the assembly platform 100 and close to the rear end of the turntable support mounting platform 300. The front and rear positions here can be referenced. Figure 1 The front and rear directions are shown.

[0033] For the aforementioned testing straightedge 400, in this embodiment, a marble straightedge is preferably made of marble. This marble straightedge has a certain weight and thickness, and is an overall long rectangular structure. It is suspended from the rear end of the top of the assembly platform 100 via a support base 5. After installation, a dial indicator can be placed on the marble straightedge to test the accuracy of the turntable. The marble straightedge can also be used to check whether the device is parallel to the ground, ensuring the stability of the device.

[0034] In this embodiment, two support bases 5 are provided, which are symmetrically arranged below the detection ruler 400 near both ends to support the detection ruler 400.

[0035] Furthermore, during the placement of the testing ruler 400, in order to enable the testing platform 400 to be quickly placed on the support base 5 through the limiting and positioning structure, the top of the support base 5 is provided with upwardly protruding positioning pins 6 and limiting blocks 7 on the front and rear sides, respectively. Because of the presence of the positioning pins 6 and limiting blocks 7, the two together form the placement position of the testing ruler 400 on the support base 5. This facilitates the accurate placement of the testing ruler 400 on the support base 5 (the testing ruler 400 is a marble ruler, which is heavy and is generally placed using lifting equipment). At this time, the position of the testing ruler 400 after placement basically meets the requirements. Of course, in some cases, there may be a slight tilt. Therefore, for further optimization, this embodiment also provides an adjustment hole 71 at the position of the limiting block 7 near the top. By opening the adjustment hole 71, a screw (not marked) can be screwed in. By adjusting the screw in and out, the placement position of the detection ruler 400 can be finely adjusted, and it can be pressed tightly against the detection ruler 400 to further stabilize its placement on the support base 5.

[0036] For the first mounting bracket 3 and the second mounting bracket 4, a front abutment block 8 and a rear abutment block 9 are respectively provided on the top near their respective front and rear sides. The first mounting bracket 3 and the second mounting bracket 4 can be made of marble or metal and are relatively short cuboid structures. The length direction of the cuboid structure is consistent with the width direction of the assembly platform 100. There is a gap between the two cuboid structures. The two cuboid structures also have multiple mounting holes (unmarked) near their top near their front and rear sides for installing the front abutment block 8 and the rear abutment block 9. After the multiple mounting holes are provided, suitable hole positions can be selected according to the actual size of the turntable center 10 to install the front abutment block 8 and the rear abutment block 9. After installation, the front abutment block 8 and the rear abutment block 9 of the first mounting bracket 3 and the second mounting bracket 4 together support and position the turntable center 10. After the support is positioned, it is sometimes necessary to make a fine adjustment to the placement of the turntable center 10. At this time, both the front stop block 8 and the rear stop block 9 are equipped with adjusting screws 12. By adjusting the adjusting screws 12, the placement of the turntable center 10 on the first mounting bracket 3 and the second mounting bracket 4 can be finely adjusted, and the turntable center 10 can be pressed tightly against it to further fix the installation of the turntable center 10.

[0037] The first mounting platform 1 and the second mounting platform 2 are made of marble. The width of the mounting platform surface of each marble mounting platform is greater than the width of the first mounting frame 3 and the second mounting frame 4. Because the turntable support part 11 is large in volume and heavy in weight, the first mounting platform 1 and the second mounting platform 2 with the above structure can bear the weight of the turntable support part 11.

[0038] For the first mounting platform 1 and the second mounting platform 2, each is further provided with an adjusting block 13 protruding from its top on its front side. The adjusting block 13 includes a block body 131 and an adjusting pressure plate 132 screwed onto the block body 131. In this way, after the turntable support 11 is suspended on the corresponding mounting platform, the adjusting pressure plate 132 can be used to finely adjust the placement position of the turntable support 11 on the one hand, and limit the position of the turntable support 11 on the other hand, thus stabilizing its placement.

[0039] In this embodiment, the slide rails 500 at the first mounting platform 1 and the second mounting platform 2 each include a first slide rail body 14 and a second slide rail body 15 symmetrically arranged front and rear. At least one slider 16 is mounted on each of the first slide rail body 14 and the second slide rail body 15, and the slider 16 is connected to the bottom of the corresponding mounting platform. It should be noted that the slide rails 500 under each mounting platform are arranged along the length of the assembly platform 100, with a gap between them. Thus, according to the size and specifications of the turntable support 11, the specific positions of the first mounting platform 1 and the second mounting platform 2 can be moved along the length of the assembly platform 100 to accommodate the installation of the turntable support 11. Furthermore, to further secure the turntable support 11, the first mounting platform 1 and the second mounting platform 2 are marble platforms, each equipped with several mounting holes 17.

[0040] After the moving positions of the first mounting platform 1 and the second mounting platform 2 are determined, in order to fix the first mounting platform 1 and the second mounting platform 2, the assembly platform 100 is also provided with mounting baffles 18 on the front and rear sides of the first mounting platform 1 and the second mounting platform 2 respectively to press against the front and rear sides of the corresponding mounting platforms.

[0041] 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.
