Description

Technical Field

[0001] The utility model relates to the technical field of straightening equipment, in particular to a novel stirring shaft straightening device. Background Art

[0002] At present, stainless steel stirring shafts have been widely used in chemical, pharmaceutical production and other fields. However, during the processing of stainless steel stirring shafts, they will inevitably encounter uncontrollable variables such as welding deviation and welding deformation, which will cause the stirring shaft to deform and bend, resulting in a large difference in concentricity between the front and back. In addition, since the main body of the stirring shaft is usually made of stainless steel, its yield point is low, and it can only be processed by pressure correction or heat correction. However, in the actual straightening process, the lack of suitable tools makes the straightening operation very difficult for the staff, and the work efficiency is low, making it difficult to ensure product quality. Utility Model Content

[0003] Aiming at the above-mentioned problems that the straightening operation is difficult and the straightening efficiency is low during the straightening of the agitator shaft by the current staff, the utility model provides a novel agitator shaft straightening device.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A new stirring shaft straightening device includes a support frame, a roundness measuring instrument and a jack. The support frame includes a supporting beam and several supporting parts. The supporting beam is located above each supporting part, and the top of each supporting part has an arc-shaped notch; the roundness measuring instrument and the jack are connected to the bottom of the supporting beam through a sliding assembly and move relative to the supporting beam.

[0006] Furthermore, the support frame also includes a support base plate and a plurality of support columns, and each of the support columns is vertically fixed on the top of the support base plate.

[0007] Furthermore, the end of the supporting crossbeam is located between the adjacent supporting columns and is welded and fixed to the upper portion of the supporting columns.

[0008] Furthermore, the supporting beam is in an I-shape.

[0009] Furthermore, the sliding assembly includes a U-shaped plate and a plurality of pulleys, and both sides of the inner wall of the U-shaped plate are connected to each of the pulleys.

[0010] Furthermore, the lower flange of the supporting beam is located between the inner bottom wall of the U-shaped plate and the pulley.

[0011] Furthermore, the sliding assembly is divided into a first sliding assembly and a second sliding assembly, the roundness measuring instrument is detachably connected to the outer bottom wall of the U-shaped plate of the first sliding assembly, and the jack is detachably connected to the outer bottom wall of the U-shaped plate of the second sliding assembly.

[0012] Furthermore, the top of the supporting base plate is provided with a sliding groove, and the sliding groove is located below the supporting beam.

[0013] Furthermore, the bottom of the support portion is arranged in the sliding groove and moves along the sliding groove.

[0014] The beneficial effects of the present invention are as follows: the present invention uses a roundness measuring instrument in conjunction with a jack to detect the bending position of the agitator shaft and apply pressure to straighten it. The operation is simple, and it can effectively improve the straightening accuracy and efficiency, reducing the failure rate in the production process. The support portion of the present invention can move along the sliding groove, providing support for the agitator shaft while also facilitating the application of pressure by the jack, thereby improving the straightening effect.

[0019] The utility model discloses a novel stirring shaft straightening device. An implementation manner of the utility model is described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 As shown, the stirring shaft straightening device includes a support frame, a roundness measuring instrument 7 and a jack 8. The support frame includes a support base plate 1, a support beam 3, a plurality of support columns 2 and a plurality of support parts 4. Each support column 2 is vertically fixed at the four corners of the top of the support base plate 1, so that there are two support columns 2 on the left side of the support base plate 1 and two support columns 2 on the right side of the support base plate 1. The support beam 3 is in an I-shape, and the left end of the support beam 3 is located between the two support columns 2 on the left side of the support base plate 1 and is welded and fixed to the upper part of the two support columns 2. Figure 2 and Figure 3As shown, the right end of the support beam 3 is located between the two support columns 2 on the right side of the support base plate 1 and is welded to the upper portions of the two support columns 2. The top of the support base plate 1 has a sliding groove 5, which is located directly below the support beam 3. The bottom of each support portion 4 is a square plate, which is positioned within the sliding groove 5 and moves left and right along the sliding groove 5. The top of each support portion 4 has an arc-shaped notch to support the agitator shaft to be straightened and facilitate its rotation. There are two support portions 4, located directly below the support beam 3.

[0021] like Figure 4 As shown, the roundness measuring instrument 7 and the lifting jack 8 are both movably connected to the support beam 3 via a sliding assembly 6, allowing them to move left and right along the support beam 3. The sliding assembly 6 comprises a U-shaped plate and several pulleys, with both sides of the inner wall of the U-shaped plate connected to each pulley. The sliding assembly 6 includes a first sliding assembly and a second sliding assembly. The roundness measuring instrument 7 is detachably connected to the outer bottom wall of the U-shaped plate of the first sliding assembly, and the lifting jack 8 is detachably connected to the outer bottom wall of the U-shaped plate of the second sliding assembly. The lower flange of the support beam 3 is located between the inner bottom wall of the U-shaped plate and the pulleys.

[0022] During use, the staff moves the two support parts 4 along the sliding groove 5 according to the specifications of the stirring shaft, and adjusts the spacing between the two support parts 4 so that the two support parts 4 can match the stirring shaft. The staff places the stirring shaft on the arc-shaped notch of the support part 4 to limit and support the stirring shaft, and at the same time facilitate the rotation of the stirring shaft. After the staff moves the roundness measuring instrument 7 along the supporting beam 3 to the appropriate position through the first sliding component, the roundness measuring instrument 7 cooperates with the rotating stirring shaft to measure the roundness of the stirring shaft. When the staff uses the roundness measuring instrument 7 to find the bending position of the stirring shaft, the jack 8 is moved to the top of the bending position of the stirring shaft through the second sliding component, and then the jack 8 is controlled to extend and press down the bending position of the stirring shaft to make it gradually straighten. Then the staff controls the jack 8 to retract and reset. The staff repeats the above operation to straighten the stirring shaft so that the concentricity of the front and back of the stirring shaft is as consistent as possible.

[0023] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
