Description

Technical Field

[0001] The utility model relates to the technical field of screw rod processing, in particular to a straightening machine for screw rod processing. Background Art

[0002] In the traditional screw processing process, straightening has always been an important and complex link. As a key component of the transmission machinery, the accuracy of the screw directly affects the performance and life of the entire equipment. However, due to the material characteristics of the screw itself and various factors in the processing process, such as machine tool accuracy, tool wear, clamping force, etc., the screw may bend or twist, thus affecting its use effect.

[0003] However, since the outer side of the lead screw is provided with threads, when the lead screw is straightened, if the existing abutment straightening method is adopted, the threads are easily damaged during the straightening, causing the lead screw to be scrapped and the use effect is poor.

[0004] Therefore, the present application provides a straightening machine for screw processing to solve the above technical problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a straightening machine for screw rod processing to solve the problem in the prior art that the thread is easily damaged by resistance when the screw rod is straightened.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A straightening machine for screw processing, comprising a base, a first side plate and a second side plate are symmetrically fixed at both ends of the upper end surface of the base, a positioning cylinder for fixing one end of the screw to be straightened is rotatably installed in the middle of the first side plate, a rotating disk for fixing the other end of the screw to be straightened is rotatably installed in the middle of the second side plate, and the positioning cylinder and the rotating disk are located on the same horizontal line;

[0008] A sliding groove is provided on the upper end surface of the base along the horizontal direction of the positioning cylinder and the rotating disk, and a straightening seat is slidably installed on the sliding groove. Two straightening plates are symmetrically fixed at both ends of the straightening seat. The top of each straightening plate is provided with a straightening opening which is located on the same horizontal line as the positioning cylinder and the rotating disk, and a straightening screw barrel adapted to the screw to be straightened is detachably installed at the end of the straightening opening.

[0010] Optionally, a handle is fixed to the edge of one side of the rotating disk away from the positioning cylinder, and a fixing pin is provided in the middle of the rotating disk. The fixing pin passes through the middle of the rotating disk and is fixed to one end of the lead screw to be processed that abuts against the middle of the rotating disk.

[0011] Optionally, a sliding block is formed on the lower end surface of the straightening seat, and the sliding block is slidably embedded in the sliding groove.

[0012] Optionally, a fixing seat connected to the straightening port is fixed to the top side of the straightening plate, and the straightening screw barrel is detachably mounted on the fixing seat.

[0013] Optionally, the port surface of the fixing seat is configured with a sliding edge, and the inner wall of the straightening screw barrel is configured with a slot, which is horizontally plugged into and matched with the sliding edge on the fixing seat to form a detachable fixation.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above scheme, thanks to the setting of the straightening seat, the two detachable straightening screw barrels on the slider can be used to be put on the screw to be straightened, and then the screw to be straightened is fixed between the positioning cylinder and the rotating disk to facilitate rotation. In the process of rotating the screw, the two straightening screw barrels can slide horizontally along the screw under the cooperation and limitation of the straightening seat and the slide groove, thereby realizing non-destructive straightening of the screw.

[0017] At the same time, thanks to the fact that the straightening screw barrel is fixed by horizontal plugging with the fixing seat, it is convenient to replace the straightening screw barrel adapted to the lead screw of different specifications, thereby improving the versatility of the device to a certain extent.

[0018] In summary, the device can not only perform non-destructive straightening of the screw to avoid damage to the thread on the screw surface and thus scrapping, but also facilitates replacement of the matching straightening screw barrel according to the screw specifications, making the device flexible to use and having a certain degree of versatility.
