Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
The invention provides a platform for detecting surface defects of shaft parts, which can be seen in figure 1 and comprises: the device comprises a base station 100, a rotating assembly 200 and a scanning assembly 300, wherein the base station 100 is used for supporting other assemblies, the rotating assembly 200 is used for rotating shaft parts, and the scanning assembly 300 is used for scanning surface defects of a workpiece.
The rotating assembly 200 is used for driving the shaft parts to rotate continuously, the scanning assembly 300 scans the outer surfaces of the workpieces, and the rotating assembly 200 drives the workpieces to rotate continuously, so that the scanning assembly 300 can completely acquire defect information of the shaft surfaces, and surface defects of the shaft parts are comprehensive.
Specifically, the abutment 100 needs to have sufficient structural strength to meet the requirements for carrying other components.
As shown in fig. 2, the rotating assembly 200 includes a rotating driving member 210 and at least one supporting member 220 arranged along a straight line, the supporting member 220 is used for driving the shaft member, and the rotating driving member 210 is connected to the shaft member to rotate the shaft member relative to the base 100. It should be noted that the number of the supporting members 220 needs to be adjusted according to the length of the workpiece to be measured, and the larger the length of the workpiece is, the more the number of the supporting members 220 needs to be, and it needs to be ensured that the supporting members 220 are uniformly arranged along the length direction of the workpiece as much as possible.
It should be noted that the supporting member 220 is used for supporting the shaft-like component, as long as the supporting member 220 does not limit the rotation of the workpiece, in a specific embodiment, the supporting member 220 includes an installation seat 221 and two supporting rollers 222 parallel to each other, the installation seat 221 is installed on the base 100, and the supporting rollers 222 are rotatably installed on the installation seat 221. The shaft part is placed between the two bearing rollers 222, and when the shaft part rotates, the bearing rollers 222 rotate along with the shaft part, so that the workpiece can rotate freely under the support of the bearing rollers 222.
It will be appreciated that the spacing between the two support rollers 222 cannot be greater than the diameter of the workpiece, otherwise the shaft parts slip out of the gap between the two support rollers 222. However, if the distance between the two support rollers 222 is too small, the height difference between the center of gravity of the workpiece and the support rollers 222 may be too large, and the center of gravity of the workpiece may be unstable, so that the workpiece may easily roll off the support rollers 222. It can be seen that the spacing between the two carrier rollers 222 needs to match the diameter of the workpiece.
On the basis of the above scheme, the distance adjusting part (not labeled in the figure) is used to enable the two carrier rollers 222 to relatively approach and separate, and to stably stay at any position on the sliding track. The relative distance between two carrier rollers 222 can be adjusted by moving the carrier rollers 222 relatively closer to and farther away from each other, so that the distance between two carrier rollers 222 can be adjusted to accommodate workpieces of different diameters.
Any mounting manner of the support rollers 222 that can adjust the distance between the two support rollers 222 is possible, for example, two sliding blocks that can translate relative to the base 100 are provided, and the two support rollers 222 are respectively rotatably mounted on the two sliding blocks, and the distance between the two support rollers 222 can be adjusted by moving the two sliding blocks. Meanwhile, a proper limiting mechanism is needed, so that the two sliding blocks can be fixed after the distance between the two bearing rollers 222 is adjusted.
In a preferred embodiment, referring to fig. 3, the carrier roller 222 includes a roller 2221 and a connecting portion 2222, the connecting portion 2222 is slidably disposed on the mounting seat 221, and a thread hole 2222a is formed in the connecting portion 2222, and the thread hole 2222a is parallel to the sliding direction of the connecting portion 2222. The drum 2221 is rotatably mounted on the connecting portion 2222, and the supporting member 220 further includes a driving rod 223, the driving rod 223 has a first thread and a second thread with opposite directions, and the first thread and the second thread are respectively screwed with the thread holes 2222a of the two connecting portions 2222. The driving rod 223 is driven to rotate to drive the two connecting portions 2222 to move toward and away from each other, and further drive the two rollers 2221 to move toward and away from each other. In order to facilitate the rotation of the driving rod 223, a rotating rod handle 2231 is provided at one end of the rotating driving rod 223, and an operator can hold the rotating rod handle 2231 to rotate the driving rod 223.
It is easy to think that the screw holes 2222a of the two connecting portions 2222 have opposite directions, and the screw directions of the first screw and the second screw are the same, so that the same effect can be achieved, and the driving rod 223 can be rotated to drive the first connecting portion 2222 and the second connecting portion 2222 to move closer to and away from each other. Further, the first and second threads may be two segments of a complete thread, provided that the screw holes 2222a of the two connection portions 2222 are opposite in direction. Alternatively, it is to be understood that the drive rod 223 may be a conventional lead screw.
Preferably, the thread pitches of the first thread and the second thread are equal, so that the two connecting portions 2222 can slide synchronously in the process of rotating the driving rod 223, which is more beneficial for adjusting the distance between the two carrier rollers 222 operated by an operator.
In addition, in order to adjust the height of the supporting member 220, the supporting member 220 further includes a lifting/lowering driving portion 224, the mounting seat 221 can slide in the vertical direction, and the lifting/lowering driving portion 224 drives the mounting seat 221 to move up and down, thereby changing the height of the entire supporting member 220.
It should be emphasized here that the platform for detecting surface defects of shaft-type parts is not limited to detecting shaft-type parts with uniform thickness, and the platform for detecting surface defects of shaft-type parts has a very wide application range. The specific situation can be seen in fig. 5, a plurality of directly different cylindrical surfaces are arranged on the part a, and the two bearing rollers 222 can stably bear shaft parts with different diameters by adjusting the distance between the two bearing rollers 222. Since different bearings 220 support different parts of the part a, the diameters of the different parts of the part a are different. The mounting seat 221 is moved up and down through the lifting driving part 224, so that the relative height between the supporting pieces 220 is changed, the axis of the part A is kept horizontal, and the part A can be attached to the supporting roller 222.
In order to make those skilled in the art understand the technical solution of the present invention more deeply, referring to fig. 6, the diameter of the part B is very large, and the part B can still be stably supported by adjusting the distance between the two bearing rollers 222, so long as the distance between the two bearing rollers 222 is sufficiently large, the part with a large diameter can be stably supported, and the detection requirement of the part with a large diameter is met.
In addition to the above-mentioned embodiments, any embodiment of the elevation driving part 224 that can drive the installation base 221 to ascend and descend is possible. For example, a hydraulic cylinder may be used to drive the mount 221 up and down. In one embodiment, the base 100 has a plurality of driving bases 110 corresponding to the supporting members 220, and the driving bases 110 have a plurality of lifting screw holes 111 and a plurality of guide holes 112 parallel to the lifting screw holes 111. The mounting base 221 has a plurality of guide rods 2211 corresponding to the guide holes 112, and the guide rods 2211 are slidably disposed in the guide holes 112, so that the mounting base 221 can slide up and down relative to the driving base 110. The lifting driving part 224 is a lifting screw, which is screwed to the lifting screw hole 111, and one end of the lifting screw is rotatably mounted on the mounting seat 221. By rotating the lifting screw, the mounting seat 221 can be controlled to lift, and the height of the supporting member 220 can be integrally adjusted. In addition, in order to facilitate the operator to rotate the lifting screw, a lifting handle 2241 is further installed at one end of the lifting screw, which is far away from the mounting seat 221.
It should be noted that the guide rod 2211 is only matched with the guide hole 112 to guide the mounting seat 221, and the embodiment having similar effect to the matching structure described above can also meet the requirement. For example, a key-slot fit may be used, or a plurality of telescoping rods may be used to connect the driving base 110 and the mounting base 221.
It will be appreciated that in some applications, it may be desirable to adjust the spacing between the supports 220, and in a preferred embodiment, the drive socket 110 may slide relative to the body of the base platform 100, so as to adjust the spacing between the supports 220.
Any rotating driving part 210 capable of driving the shaft parts to rotate is feasible, and the rotating driving part 210 can be in direct contact with the shaft parts through a proper transmission mode, so that the driving shaft parts rotate. The rotary driving element 210 can also be used to drive the carrying roller 222 to rotate, thereby indirectly driving the shaft parts to rotate. In a specific embodiment, referring to fig. 4, the rotary driving element 210 drives two supporting rollers 222 on any one of the supporting members 220 to rotate in the same direction, and the two supporting rollers 222 rotate in the same direction to support the shaft component. It should be emphasized that the two carrier rollers 222 may be both in transmission connection with the rotary driving element 210, so that the two carrier rollers 222 rotate synchronously, or the rotary driving element 210 may be in transmission connection with one of the carrier rollers 222, so that one carrier roller 222 is a driving roller and the other carrier roller 222 is a driven roller. The rotation driving portion 212 drives the two carrier rollers 222 to rotate in the same direction. The support rollers 222 support the shaft-like parts from the bottom, so that the workpiece is prevented from being shielded by the rotary driving element 210.
Any embodiment capable of driving the carrier roller 222 to rotate is possible, and in a preferred embodiment, the rotary driving member 210 includes a driving roller 2121 and a rotary motor 2122, the driving roller 2121 is disposed parallel to the two carrier rollers 222, the driving roller 2121 presses against the carrier roller 222, and the rotary motor 2122 drives the driving roller 2121 to rotate to drive the carrier roller 222.
In one embodiment, the scanning assembly 300 has a scanning element 310 mounted above a shaft-like part to detect surface defects of the shaft-like part. The scanning unit 310 may acquire defect information of the workpiece surface by using ultrasonic waves, visual images, and the like. An operator can select a proper type of scanning element 310 according to the characteristics of the shaft parts, so as to obtain an ideal detection effect.
It can be understood that, in actual use, the relative position between the scanning element 310 and the workpiece often needs to be adjusted, so that the scanning element 310 can more accurately know the defect information of the workpiece surface.
Specifically, the scanning assembly 300 further includes a distance adjusting member 320, the distance adjusting member 320 is mounted on the base 100 and has a moving end connected to the scanning member 310, and the moving end can drive the scanning member 310 to move in a three-dimensional space relative to the base 100 and can stay at any position on a moving track thereof.
Any embodiment that can adjust the relative position between the scanning element 310 and the workpiece is possible, for example, the distance adjusting element 320 may be a robot arm, the robot arm is composed of a plurality of movable joints connected in the first place, one end of the robot arm is installed on the base station 100, and the other end of the robot arm is installed with the scanning element 310, so that the relative position between the scanning element 310 and the shaft-like part can be adjusted by means of the robot arm.
In another embodiment, the distance adjusting member 320 includes a first translating member 321, a second translating member 322 and a third translating member 323, the first translating member 321 is slidably disposed on the base 100, the second translating member 322 is slidably disposed on the first translating member 321, the third translating member 323 is slidably disposed on the second translating member 322, the sliding directions of the first translating member 321, the second translating member 322 and the third translating member 323 are perpendicular to each other, and the moving end is located on the third translating member 323. The moving tracks of the first translation element 321, the second translation element 322, and the third translation element 323 are perpendicular to each other, so that the scanning element 310 can be driven to move freely in a three-dimensional space, and the relative position between the scanning element 310 and the shaft-like part can be freely adjusted.
In a specific application scenario of the above solution, the moving track of the first translating element 321 is parallel to the shaft-like element, the second translating element 322 is moved in the horizontal direction, and the third translating element 323 is moved in the vertical direction. If the scanning unit 310 cannot scan the entire workpiece at a single time, the scanning unit 310 can scan the workpiece segment by segment along the length direction of the workpiece, and by adjusting the relative position between the second translation unit 322 and the first translation unit 321 and the relative position between the third translation unit 323 and the second translation unit 322, the scanning unit 310 can acquire the outer surface information of a certain segment of the workpiece, and then gradually move the first translation unit 321, so as to gradually acquire the entire outer surface information of the workpiece.
The distance between the supporting parts 220 is adjusted according to the length of the shaft parts, and the distance between the two supporting rollers 222 is adjusted according to the diameter of the shaft parts, so that the supporting parts 220 are matched with the shaft parts. The shaft-like part is placed between the two supporting rollers 222, so that the shaft-like part can rotate relative to the base 100, and the transmission roller is driven to rotate by the rotating motor 2122, so that the workpiece is driven to rotate continuously by the rotating driving roller 2121. Meanwhile, the scanning element 310 is erected above the shaft part, and the surface of the shaft part is obtained by using the scanning element 310. Meanwhile, the relative position between the scanning part 310 and the shaft part can be adjusted by the distance adjusting part 320, so that the scanning part 310 can scan the workpiece at a proper position, and a more accurate detection result is obtained. With the continuous rotation of the shaft-like part, the scanning element 310 can be the outer surface of the shaft-like part completely, so that the surface defect condition of the shaft-like part can be comprehensively evaluated.
The above-described embodiments of the present invention should not be construed as limiting the scope of the present invention. Any other corresponding changes and modifications made according to the technical idea of the present invention should be included in the protection scope of the claims of the present invention.
