Therefore, there is an urgent need for a device that can adjust the defective products with insufficient roundness or straightness to make them qualified. Utility Model Content

[0004] In view of the above technical problems, the utility model provides a rounding and straightening device which is convenient for adjusting clamping.

[0005] The utility model provides a rounding and straightening device, which is characterized by comprising a working support, the top of the working support is fixedly connected to a fixing frame, the left and right sides of the middle of the fixing frame are respectively fixedly connected to positioning plates, one side of the positioning plate is movably connected to an adjusting rotating rod up and down, a limiting frame is fixedly installed between the two positioning plates, a sliding groove is arranged in the middle of the limiting frame, a moving block is movably connected in the sliding groove, the top of the moving block is connected to a screw rod, a sleeve is arranged on the outside of the screw rod, the top of the sleeve is connected to an adjusting handle, and the front side of the moving block is connected to another adjusting rotating rod.

[0006] Connecting plates are respectively arranged at the front and rear of the positioning plate, and a plurality of mounting holes are arranged on the connecting plates.

[0007] The adjusting rotating rod is connected to the connecting plate through a mounting piece and a mounting hole.

[0008] The screw rod is threadedly connected with the sleeve.

[0009] The beneficial effects of the utility model are as follows: the utility model is a rounding and straightening device, which is provided with a plurality of adjusting rotating rods, wherein the adjusting rotating rods on the positioning plate can be adjusted to any position, so that it can be used for circular ring samples of different diameters and samples of different lengths; the adjusting rotating rod in the middle is connected to the moving block, and the moving block can move up and down according to the cooperation of the adjusting handle and the screw rod, so that it can better adjust the roundness and straightness. The utility model can clamp and fix unqualified samples, and through an external driving device, the samples can be rotated between the adjusting rotating rods, so as to adjust their roundness and straightness. The operation is simple and convenient, and the unqualified rate is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Example 1

[0016] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0017] As shown in the figure, the utility model provides a rounding and straightening device, which is characterized in that it includes a working support 1, the top of the working support 1 is fixedly connected to a fixing frame 2, the left and right sides of the middle of the fixing frame 2 are respectively fixedly connected to positioning plates 3, one side of the positioning plate 3 is movably connected to an adjusting rotating rod 4 at the top and bottom, a limiting frame 9 is fixedly installed between the two positioning plates 3, a slide groove is arranged in the middle of the limiting frame 9, a moving block 10 is movably connected in the slide groove, the top of the moving block 10 is connected to a screw rod, a sleeve 6 is arranged on the outside of the screw rod, the top of the sleeve 6 is connected to an adjusting handle 5, and the front side of the moving block 10 is connected to another adjusting rotating rod 4.

[0018] Connecting plates are respectively arranged at the front and rear of the positioning plate 3 , and a plurality of mounting holes are arranged on the connecting plates. The adjusting rotating rod 4 is connected to the connecting plates through mounting parts and the mounting holes.

[0019] The screw rod is threadedly connected to the sleeve 6 .

[0020] Example 2

[0021] When the utility model is used: firstly, according to the diameter of the sample 7, the adjusting rod 4 on the positioning plate 3 is adjusted so that it can be installed on the mounting hole at the appropriate position. After the installation is completed, the sample 7 is adjusted according to the diameter of the sample 7. Figure 1 In the example, the adjusting handle 5 is overlapped on the adjusting rotating rod 4, and the adjusting handle 5 is rotated to drive the sleeve 6 to rotate. The rotation of the sleeve 6 drives the internal screw to rotate. However, since the moving block at the bottom of the screw cannot rotate, it will move up and down on the limit frame to adjust the supporting force of the adjusting rotating rod on the sample. After the adjustment is completed, the sample is driven by an external driving device to rotate in the adjusting rotating rod 4, and its roundness or straightness is automatically adjusted during the rotation.

[0022] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The various components mentioned in the utility model are common technologies in the existing field. The technicians in this industry should understand that the utility model is not limited by the above embodiments.
