[0023] The following further elaborates the present invention in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0024] Refer to Figures 1 to 2 , Specific Embodiment 1. This Specific Embodiment 1 provides a support device for a turntable, including a circular plate 55, a plurality of support mechanisms and a plurality of fixing brackets. A roller 51 is provided at the top of each support mechanism, the bottom of the circular plate 55 is placed on the roller 51, and a plurality of fixing brackets are arranged on the circular plate 55, and the fixing brackets are detachably connected to the fixture 46.

[0025] Each support mechanism further includes a base plate 48, a support frame 49, and a mounting bracket 50 for mounting rollers 51. The bottom of the support frame 49 is welded to the base plate 48 through a connecting plate 52, and the top of the support frame 49 is detachably connected to the mounting bracket 50; the base plate 48 is fixed to the bottom plate. The fixing brackets can be increased or decreased according to actual situations.

[0026] The support device for the turntable 47 includes four bottom plates for connecting to the ground. The four bottom plates are arranged in pairs opposite to each other, for example, symmetrically distributed front and back, left and right, and are the first bottom plate 1, the second bottom plate 2, the third bottom plate 3, and the fourth bottom plate 4 respectively.

[0027] The first bottom plate 1 is equipped with a first support mechanism 5 and a second support mechanism 6, which are symmetrically distributed at both ends of the first bottom plate 1 respectively; the second bottom plate 2 is equipped with a third support mechanism 7 and a fourth support mechanism 8, which are symmetrically distributed at both ends of the second bottom plate 2 respectively; the third bottom plate 3 is equipped with a fifth support mechanism 9 and a sixth support mechanism 10, which are symmetrically distributed at both ends of the third bottom plate 3 respectively; the fourth bottom plate 4 is equipped with a seventh support mechanism 11 and an eighth support mechanism 12, which are symmetrically distributed at both ends of the fourth bottom plate 4 respectively; the eight support mechanisms are also arranged in pairs opposite to each other. In this way, the eight support mechanisms provide a more uniform supporting force for the annular plate 55. After the fixture 46 is connected to the fixing bracket on the annular plate 55, the weight of the fixture 46 can also be evenly distributed to the eight support mechanisms.

[0028] The annular plate 55 is composed of a first arc plate 37, a second arc plate 38, a third arc plate 39, a fourth arc plate 40, a fifth arc plate 41, a sixth arc plate 42, a seventh arc plate 43, and an eighth arc plate 44 to form the annular plate 55, which is convenient for disassembling and replacing parts.

[0029] The support device for the turntable 47 includes a first fixing bracket 13, a second fixing bracket 14, a third fixing bracket 15, a fourth fixing bracket 16, a fifth fixing bracket 17, a sixth fixing bracket 18, a seventh fixing bracket 19, an eighth fixing bracket 20, a ninth fixing bracket 21, a tenth fixing bracket 22, an eleventh fixing bracket 23, a twelfth fixing bracket 24, a thirteenth fixing bracket 25, a fourteenth fixing bracket 26, a fifteenth fixing bracket 27, and a sixteenth fixing bracket 28. The sixteen fixing brackets are evenly arranged on the annular plate 55.

[0030] Above the annular plate 55 composed of eight arc-shaped plates, there are sixteen fixed brackets, which fix the upper fixture 46 more comprehensively. Below the annular plate 55, there are eight support mechanisms, so that the support device for the turntable 47 can be supported more stably. In addition, the annular plate 55 is supported by eight support mechanisms below. The support mechanisms are equipped with rollers 51. By contacting the annular plate 55 through the rollers 51, the turntable 47 drives the annular plate 55 to rotate on the rollers 51. Through the support mechanisms, the annular plate 55 is not only supported comprehensively, but also the rotation of the annular plate 55 is assisted by the rollers 51 of the support mechanisms. The support device for the turntable 47 is simple to operate and convenient to install, greatly reducing the device cost.

[0031] The support device for the turntable 47 also includes eight flat plates. The first flat plate 29 is on the second fixed bracket 14 and the third fixed bracket 15. The second flat plate 30 is on the fourth fixed bracket 16. The third flat plate 31 is on the sixth fixed bracket 18. The fourth flat plate 32 is on the eighth fixed bracket 20. The fifth flat plate 33 is on the ninth fixed bracket 21 and the tenth fixed bracket 22. The sixth flat plate 34 is on the twelfth fixed bracket 24. The seventh flat plate 35 is on the fourteenth fixed bracket 26. The eighth flat plate 36 is on the sixteenth fixed bracket 28. Each flat plate mainly serves to support and fix the fixture 46 or the auxiliary frame 45. The shapes of the flat plates can be different to ensure the effective area contacts the support points (the number of fixtures 46 supported on each flat plate is different). When the fixed fixtures 46 are different, the flat plates can be replaced, or can be increased or decreased according to the actual situation to avoid too many flat plates increasing the unnecessary weight of the annular plate 55. That is to say, by installing flat plates on each fixed bracket, more fixtures 46 can be installed on the fixed bracket, making it more stable.

[0032] The working principle and usage process of the support device for the turntable 47 in this Embodiment 1: Fix the turntable 47 inside the annular plate 55. A number of support mechanisms are fixed to the ground through the corresponding bottom plates. A number of fixed brackets are fixed with the fixture 46. Through the support of the annular plate 55 by the support mechanisms, when the turntable 47 rotates, the annular plate 55 rotates with the assistance of the rollers 51 of the support mechanisms, so that the fixture 46 rotates to the designated position for work.

[0033] See Figure 1, a screw rod 53 and a nut 54 for pre-positioning before the installation of the support frame 49 are further provided at the bottom of the support frame 49. The support frame 49 is threadedly connected to the screw rod 53. Before the installation of the support frame 49, the support frame 49 is adjusted to a proper height by using the screw rod 53 and the nut 54 at the bottom of the support frame 49, and then the bottom of the support frame 49 and the side surface of the connecting plate 52 are welded, and the bottom of the connecting plate 52 is welded to the base plate 48, so that the support frame 49 can be installed at a specified height, ensuring the height of the roller 51 at the top of the support frame 49, ensuring the height of the circular ring plate 55 on the roller 51, ensuring the height of the fixing bracket on the circular ring plate 55, and ensuring that the height of the fixture 46 connected to the fixing bracket meets the processing requirements of the workpiece on the turntable 47. The four connecting plates 52 respectively correspond to the four circumferences at the bottom of the support frame 49 to prevent subsequent shaking of the support frame 49.

[0034] See Figure 2 , the supporting device for the turntable 47 further includes an auxiliary frame 45 for connecting the fixture 46. The auxiliary frame 45 is rectangular, and the auxiliary frame 45 is detachably connected to the eleventh fixing bracket 23, the twelfth fixing bracket 24, the thirteenth fixing bracket 25, the fourteenth fixing bracket 26, the fifteenth fixing bracket 27 and the sixteenth fixing bracket 28 respectively.

[0035] When the circular ring plate 55 rotates, the auxiliary frame 45 can also be driven to rotate synchronously, and the fixture 46 on the auxiliary frame 45 can also rotate synchronously, facilitating subsequent adjustment of the angle of the fixture 46 and realizing clamping of the workpiece on the turntable 47 at different angles.

[0036] The above are only the preferred embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
