Referring to fig. 1 to 3, the wheel dresser roller quick-assembly structure according to an embodiment of the present utility model includes a dresser spindle 100, an expansion adjustment mechanism and a dressing roller 200, wherein the expansion adjustment mechanism is disposed at the end of the dresser spindle 100 and is provided with an expansion portion capable of radially adjusting opening and closing; the trimming roller 200 is provided with a positioning inner ring, and is sleeved outside the expansion part through the positioning inner ring. When the expansion part is in the folded state, the dressing roller 200 can be smoothly sleeved on or taken off from the expansion part, and when the expansion part is in the unfolded state, the dressing roller 200 is tightly expanded and fixed, so that the dressing roller rotates synchronously with the main shaft 100 of the trimmer. Therefore, the quick-assembling structure of the grinding wheel dresser roller adjusts the opening and closing of the expansion part through the expansion adjusting mechanism, so that the positioning inner ring of the dressing roller 200 is expanded, fastened and loosened, and compared with the mode of uniformly distributing screws for installation and heating assembly, the disassembling and assembling efficiency of the roller is greatly improved. And only the outer precision of the expanding portion needs to be ensured, so that the installation precision of the finishing roller 200 can be ensured, and compared with the traditional mode, the precision is easier to control.
In some embodiments of the present utility model, the expanding portion employs an expanding disc spring 400, and the mounting and fixing of the dressing roller 200 are performed by the characteristic that the expanding disc spring 400 is pressed at both ends to expand the expanding outward. Referring to fig. 2, in an embodiment, the expanding disc spring 400 is provided with a positioning inner ring 402, an expanding outer ring 401 and an opening and closing connection portion connected between the positioning inner ring 402 and the expanding outer ring 401, both the inner wall of the positioning inner ring 402 and the outer wall of the expanding outer ring 401 are coaxially arranged with the main shaft 100 of the trimmer, and the included angles between the opening and closing connection portion and the positioning inner ring 402 and the expanding outer ring 401 are larger than 90 °. By adopting the structural arrangement of the embodiment, when the expansion disc spring 400 is pressed, the expansion disc spring acts on the opening and closing connecting part, so that the included angle between the expansion disc spring and the axis of the main shaft 100 of the trimmer is increased, and the expansion outer ring 401 is moved outwards to realize radial expansion. On the contrary, after the pressure is withdrawn, the opening and closing connecting part is reset, so that the expansion outer ring 401 is driven to shrink inwards, and radial folding is realized. The expanding disc spring 400 can ensure coaxiality with the dresser main shaft 100, thereby ensuring coaxiality of the dressing roller 200 with the dresser main shaft 100 when expanding the dressing roller 200. On this basis, radial reference positioning of the dressing roller 200 is achieved. The expanding disc spring 400 can be integrally made of spring steel, so that the corresponding elastic deformation requirement and the acting force on the trimming roller 200 during expanding can be met. In actual setting, the outer diameter of the expansion disc spring 400 (i.e. the outer diameter of the expansion outer ring 401) and the size parameter between the positioning inner ring of the trimming roller 200 can be set to be in clearance fit, so that the expansion fastening can be realized only by slightly expanding the expansion disc spring 400, otherwise, the loosening of the trimming roller 200 can be realized only by slightly contracting the expansion disc spring 400, thereby not only improving the dismounting efficiency, but also being beneficial to ensuring the precision.
Since the grinding wheel dresser controls the dressing roller 200 to rotate during operation, in order to ensure the clamping stability of the dressing roller 200, in some embodiments of the present utility model, the expansion adjustment mechanism is provided with an anti-rotation positioning structure, which is disposed at least at one end of the expansion disc spring 400 and is used for positioning the angle of the expansion disc spring 400 around the axis of the dresser spindle 100, that is, for achieving anti-rotation fixation of the expansion disc spring 400. Specifically, the anti-rotation positioning structure can be realized only by setting a corresponding pin shaft structure or key position structure between the trimmer main shaft 100 and the expanding disc spring 400 for positioning, and a person skilled in the art can flexibly set the anti-rotation positioning structure according to actual conditions.
Referring to fig. 2, in some embodiments of the present utility model, a mounting shaft section 101 is provided at the end of the dresser main shaft 100, and a shoulder 102 is formed by the mounting shaft section 101. The expanding disc spring 400 is sleeved on the mounting shaft section 101 and abuts against the shaft shoulder 102 formed by the mounting shaft section 101, and the height of the expanding disc spring 400 is slightly higher than that of the mounting shaft section 101. The expansion adjusting mechanism is provided with a roller gland 300, and the roller gland 300 can be movably and adjustably arranged at the tail end of the mounting shaft section 101 along the axial direction of the trimmer main shaft 100 and is abutted against the expansion disc spring 400. Since the height of the expanding disc spring 400 is higher than that of the mounting shaft section 101, the adjustment distance between the roller gland 300 and the mounting shaft section 101 is kept, so that the axial adjustment is ensured. The other end of the expansion disc spring 400 is positioned by the shaft shoulder 102, which is beneficial to simplifying the structural composition and ensuring the positioning precision. The finishing roller 200 can also be positioned in a manner of abutting against the shaft shoulder 102, so that the high-precision installation and fixation can be realized through the expansion fastening of the expansion disc spring 400, and the axial and radial installation precision of the finishing roller 200 can meet the design requirement.
Referring to fig. 2, in some embodiments of the present utility model, the end of the installation shaft section 101 is coaxially provided with an installation cavity, the bottom center of the installation cavity is provided with an installation hole, the roller gland 300 is provided with a guide part 302 adapted to the installation cavity and an end cover 301 located outside the installation cavity, and the roller gland 300 is provided with an adjusting screw 500 installed at the installation hole. With the structural arrangement of the embodiment, the roller gland 300 realizes guiding through the cooperation of the guide part 302 and the side wall of the installation cavity, so that the roller gland 300 can only move and adjust along the axial direction of the main shaft 100 of the trimmer, and no radial displacement occurs.
Referring to fig. 2, in some embodiments of the present utility model, two ends of the expanding disc spring 400 are provided with a stress surface that is attached to the end cover 301 and the shoulder 102 of the mounting shaft segment 101, and positioning holes are provided between the stress surface and the corresponding end cover 301 and the shoulder 102 of the mounting shaft segment 101. The anti-rotation positioning structure comprises a positioning hole arranged between the expanding disc spring 400 and the shaft shoulder 102 of the mounting shaft section 101, and an anti-rotation positioning pin 600 arranged in the positioning hole between the expanding disc spring 400 and the end cover 301.
To ensure smooth ingress and egress of the dressing roller 200, in some embodiments of the utility model, the outer diameter of the end cap 301 is smaller than the outer diameter of the expanding outer ring 401.
In addition, to facilitate verification of the dressing roller 200, in some embodiments of the present utility model, the outer surface of the dressing roller 200 is provided with a radial datum surface 202 and an axial datum surface 201.
It should be noted that, the end cover 301 may also be provided with a protrusion downward toward the expanded disc spring 400, so that the expanded disc spring 400 can realize the effect of the end cover 301 on the expanded disc spring 400 without being higher than the mounting shaft section 101.
Considering that the expansion disc spring 400 may receive a radial force in the deformation process, the rotation preventing locating pin 600 only needs to realize rotation limitation of the expansion disc spring 400, so that one of every two corresponding locating holes can be set to be a waist-shaped hole, the length direction of the waist-shaped hole is consistent with the radial direction of the trimmer spindle 100, and the rotation preventing locating pin 600 is fixed through one locating hole and realizes radial fine adjustment through the other locating hole, so that stress in the deformation process of the expansion disc spring 400 is avoided.
Referring to fig. 2, in some embodiments, the wheel dresser roller quick-assembly structure includes a dresser main shaft 100, an expansion adjustment mechanism, and a dressing roller 200, wherein an end of the dresser main shaft 100 is provided with a mounting shaft section 101, an axle center of the mounting shaft section 101 is coaxially provided with a mounting cavity, and a bottom center of the mounting cavity is provided with a mounting hole. The expansion adjusting mechanism comprises an expansion disc spring 400 sleeved on the mounting shaft section 101 and a roller gland 300 fixed at the tail end of the mounting shaft section 101 through the matching of an adjusting screw 500 and a mounting hole. The roller gland 300 is divided into a guide 302 slidably fitted within the mounting cavity and an end cap 301 located outside the mounting cavity. The lower end of the expansion disc spring 400 abuts against the shaft shoulder 102 formed by the mounting shaft section 101, and the upper end of the expansion disc spring is slightly higher than the mounting shaft section 101, so that an adjusting distance is formed between the end cover 301 and the end of the mounting shaft section 101. The trimming roller 200 is provided with a positioning inner ring sleeved on the outer side of the expanding disc spring 400, and the lower end of the trimming roller is abutted against the shaft shoulder 102 formed by the mounting shaft section 101. The outer diameter of the end cap 301 is smaller than the diameter of the positioning inner ring. The dimensional tolerance between the positioning inner ring and the expanding disc spring 400 is clearance fit. With the structural arrangement of the present embodiment, only the adjusting screw 500 needs to be loosened, the end cap 301 moves upward under the action of the expanding disc spring 400, and the dressing roller 200 can be smoothly loaded and unloaded. After the roller 200 to be repaired is installed, the expansion disc spring 400 can be pressed tightly through the end cover 301 by tightening the adjusting screw 500, so that the expansion fixation of the roller 200 to be repaired is realized. Because the two are in clearance fit, the adjusting amplitude of the adjusting screw 500 is not large, and the quick assembly and disassembly are convenient.
It should be noted that, the expansion adjusting mechanism in the present utility model may also adopt other structures capable of realizing the opening and closing adjustment, and only the trimming roller 200 needs to be clamped and fixed from the inside.
The present utility model has been described in detail with reference to the embodiments, but the present utility model is not limited to the embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model.
