Description

Technical Field

[0001] The present invention relates to the technical field of roller concentricity detection, and in particular to a roller concentricity detection device. Background Art

[0002] In the hot stamping process, roller concentricity is a key component, and its critical role in product processing precision and production efficiency is crucial. Roller concentricity represents the offset between the roller's center and the axis of rotation during rotation. This parameter directly impacts key performance indicators during the hot stamping process, such as pressure distribution uniformity and the clarity of the printed pattern. Poor roller concentricity not only increases product scrap rates but also increases equipment wear and reduces production efficiency. Therefore, accurate roller concentricity testing is crucial.

[0003] Most existing concentricity detection devices use a single-point detection method, which can only detect the concentricity of the roller at specified locations along its axial and circumferential directions. This detection method has significant drawbacks: because the concentricity of the roller at various axial and circumferential positions may vary in actual operation, the test results at a specific location cannot fully reflect the overall concentricity of the roller. As a result, the test data lacks representativeness and cannot meet the requirements of high-precision production. In addition, the position of the detection device needs to be adjusted when testing different locations, which makes the operation steps complicated and the detection efficiency low.

[0004] Therefore, it is urgent to propose a roller concentricity detection device and method to solve the above problems. Summary of the Invention

[0041] like Figures 1 to 8As shown, this embodiment provides a roller concentricity detection device, including a base plate 1, a clamping mechanism 2, a first drive assembly 3, a transmission mechanism 4 and a detection mechanism 5. The clamping mechanism 2 is used to clamp the roller 100. The first drive assembly 3 is arranged on the base plate 1, and the output end is connected to the clamping mechanism 2 for driving the clamping mechanism 2 to drive the roller 100 to rotate around its axis; the detection mechanism 5 is used to detect the concentricity of the roller surface of the roller 100, and the transmission mechanism 4 is connected between the detection mechanism 5 and the output end of the first drive assembly 3; wherein, when the first drive assembly 3 drives the clamping mechanism 2 to drive the roller 100 to rotate around its axis When the line rotates, the transmission mechanism 4 is configured to drive the detection mechanism 5 to move alternately and intermittently along the axial direction of the roller 100 and around the circumference of the roller 100, so that the detection component 52 switches in sequence in a dynamic feed trajectory to act on different axial and circumferential positions of the roller, and acts on the surface of the roller body in a high-coverage, multi-area, automated measurement manner, so as to achieve an overall and comprehensive detection of the concentricity of the roller 100, and can improve the detection accuracy and detection efficiency, thereby effectively improving the quality of the hot stamping process, reducing the product scrap rate, improving production efficiency, reducing equipment loss, and meeting the strict requirements of high-precision production of modern hot stamping technology.

[0042] The first drive assembly 3 includes a drive member 31, a driving roller 32, a driven roller 33, and a transmission belt 34. The driving roller 32 and the driven roller 33 are arranged parallel and spaced apart along the radial direction of the roller 100. The clamping mechanism 2 is connected to the driven roller 33. The driving roller 32 and the driven roller 33 jointly tension the transmission belt 34. The output end of the drive member 31 is connected to the driving roller 32 to drive the driving roller 32 to drive the driven roller 33 to rotate, thereby driving the clamping mechanism 2 to rotate, thereby driving the roller 100 to be measured to rotate, which is conducive to improving the automation level of concentricity detection and thus improving detection efficiency. Optionally, the drive member 31 includes but is not limited to a drive motor, a pneumatic motor, or a hydraulic motor, which is not limited here.

[0043] Furthermore, the transmission mechanism 4 includes a transmission rod 41, a first transmission gear 42, a mounting frame 43, a spline shaft 44, a spline sleeve 45, a second transmission gear 46 and a transmission cylinder assembly 47. One end of the transmission rod 41 is coaxially connected to the active roller 32, and the other end is provided with a first transmission gear 42. The second transmission gear 46 is rotatably arranged on the mounting frame 43. The spline shaft 44 is coaxially connected to the second transmission gear 46. The spline sleeve 45 is spline-connected to the spline shaft 44, and the detection mechanism 5 is connected to the spline sleeve 45. The transmission cylinder assembly 47 is transmission-connected between the first transmission gear 42 and the second transmission gear 46 and the spline sleeve 45, and is used to drive the second transmission gear 46 to rotate or drive the spline sleeve 45 to move axially along the roller 100, thereby driving the detection mechanism 5 on the spline sleeve 45 to move alternately and intermittently along the axial direction of the roller 100 and around the circumference of the roller 100.

[0044] like Figures 1 to 5 As shown, specifically, the transmission cylinder assembly 47 includes a transmission cylinder 471, a transmission disk 472 and a transmission member 473. The transmission disk 472 is coaxially connected to one end of the transmission cylinder 471. The transmission disk 472 is circumferentially provided with a plurality of arcuate teeth 4721 for meshing with the first transmission gear 42. A plurality of spaced tooth blocks 474 are arranged at one end of the transmission cylinder 471 for meshing with the second transmission gear 46. A transmission groove 475 is also provided on the circumference of the transmission cylinder 471. The transmission groove 475 is formed by connecting a horizontal groove and an oblique groove in sequence end to end. The tooth block 474 corresponds to the horizontal groove position of the transmission groove 475. A limiting ring 451 is provided on the spline sleeve 45. A limiting groove is provided on the surface of the limiting ring 451. One end of the transmission member 473 is pinned to the mounting frame 43, and the other end is slidably connected to the transmission groove 475 and the limiting groove on both sides. When the tooth block 474 meshes with the second transmission gear 46, the transmission member 473 is slidably connected in the horizontal groove. At this time, the transmission member 473 remains in an axial position along the roller 100, and the tooth block 474 acts on the second transmission gear 46 to drive the second transmission gear 46 to drive the spline shaft 44 to rotate, thereby driving the spline sleeve 45 to rotate circumferentially once, so that the detection component 52 connected to the spline sleeve 45 rotates a certain angle; when the gap between adjacent tooth blocks 474 acts on the second transmission gear 46, the first transmission gear 42 stops rotating. At this time, the transmission member 473 is slidably connected in the inclined groove and slides along the inclined groove with the rotation of the transmission cylinder 471, thereby driving the spline sleeve 45 to slide along its axial direction on the spline shaft 44; this cycle repeats, and when the transmission cylinder 471 rotates one circle, it can drive the detection component 52 to move alternately along the axial direction of the roller 100 and around the circumference of the roller 100, forming a stepped step point switching detection mode on the roller surface of the roller 100.

[0045] Among them, the transmission cylinder assembly 47 also includes a rotating shaft 476, on which the transmission cylinder 471 and the transmission disk 472 are coaxially connected. The rotating shaft 476 is rotatably connected to the mounting frame 43, providing a reliable support basis for the transmission cylinder 471 and the transmission disk 472, which can greatly enhance the stability of the rotational connection between the transmission cylinder assembly 47 and the mounting frame 43, and improve the transmission accuracy and transmission efficiency.

[0046] like Figure 5As shown, the transmission member 473 includes a first connecting rod 4731, a second connecting rod 4732, a third connecting rod 4733 and a limiting column. A mounting block 431 is provided on the mounting frame 43. The mounting block 431 is arranged between the transmission cylinder 471 and the spline sleeve 45. The first connecting rod 4731 and the second connecting rod 4732 are pinned on both sides of the mounting block 431 respectively. The ends of the first connecting rod 4731 and the second connecting rod 4732 away from the mounting block 431 are connected with the third connecting rod 4733. The two ends of the third connecting rod 4733 extend into the transmission groove 475 and the limiting groove respectively and are provided with a limiting column. The limiting column is clamped in the transmission groove 475 or the limiting groove and can slide in the transmission groove 475 or the limiting groove to ensure the stability of the connection between the third connecting rod 4733 and the transmission groove 475 and the limiting groove, thereby realizing the transmission connection between the spline sleeve 45 and the transmission groove 475.

[0047] like Figure 5 and Figure 6 As shown, the detection mechanism 5 includes an adjusting component 51 and a detection component 52 installed on the adjusting component 51. The detection end of the detection component 52 is configured to abut against the roller surface of the roller 100, so as to detect the concentricity of the abutment position during the rotation of the roller 100 around its axis. The adjusting component 51 is configured to adjust the distance between the detection end of the detection component 52 and the axis of the roller 100, and can adapt to the detection requirements of rollers 100 with different diameters, thereby improving the versatility and flexibility of the roller concentricity detection device, thereby reducing the detection cost and improving the detection efficiency.

[0048] The inspection assembly 52 includes a bracket 521 and at least two form and position tolerance gauges 522 mounted on the bracket 521. The at least two form and position tolerance gauges 522 are spaced apart along the axial direction of the roller 100, and the inspection ends of the form and position tolerance gauges 522 abut against the roller surface of the roller 100. Inspection using at least two form and position tolerance gauges 522 can improve inspection efficiency and reliability of inspection results. The form and position tolerance gauges 522 include micrometers or dial indicators.

[0049] Optionally, the detection mechanism 5 also includes a detection frame 523, a pressure detection member 524, a detection lever 525 and an elastic member 526.

When the roller 100 rotates, one end of the detection lever 525 always acts on the outer wall of the roller 100, and the other end acts on the elastic member 526, so that the pressure detection member 524 generates a pressure value. When detecting the concentricity of the roller 100, once the roller 100 has a concentricity deviation, the pressure indication of the pressure detection member 524 will also change accordingly. By the fluctuation of the pressure indication of the pressure detection member 524, it can be quickly determined whether there is a concentricity deviation.

[0050] The pressure detection element 524 includes but is not limited to a strain gauge pressure sensitive sensor or a piezoelectric pressure sensitive sensor, which is not limited here.

The detection component 52 is connected to the sleeve 512, and the sleeve 512 is slidingly connected to the adjustment frame 511 along the extension direction of the screw 513. By rotating the screw 513, the sleeve 512 can be driven to move along the extension direction of the screw 513, thereby adjusting the distance between the detection component 52 and the roller 100 to ensure that the detection end of the detection component 52 abuts against the roller surface of the roller 100.

[0052] Furthermore, in order to facilitate the screwing of the screw 513 , a rod cap 515 is connected to one end of the screw 513 away from the roller 100 , and the rod cap 515 extends outside the adjustment frame 511 , so that the staff can perform the screwing operation.

[0054] like Figure 7 and Figure 8As shown, the clamping mechanism 2 includes a first inner support assembly 21 and a second inner support assembly 22 that are coaxial and oppositely arranged. The first inner support assembly 21 and the second inner support assembly 22 are respectively used to internally support the two ends of the fixed roller 100, wherein the first inner support assembly 21 and the second inner support assembly 22 both include a telescopic driving member 211, a support column 212, a fixed ring 213, a movable ring 214, a plurality of first support rods 215, and a second support rod 216 corresponding to the first support rod 215, a mounting strip 217 and an inner support member 218. The fixed ring 213 is fixedly sleeved on the support column 212, and the movable ring 214 is slidably sleeved on the support column 212. The circumferentially spaced pins of the fixed ring 213 are connected to the plurality of first support rods 215. The movable ring 214 is A second support rod 216 is pinned to the corresponding circumferential direction, and the two ends of the mounting bar 217 are pinned to the corresponding first support rod 215 and second support rod 216 respectively. An inner support member 218 is installed on each mounting bar 217. The output end of the telescopic drive member 211 is connected to the movable ring 214 for driving the movable ring 214 to move closer to or away from the fixed ring 213, thereby adjusting the distance between the inner support member 218 and the axis of the support column 212, so that the inner support member abuts against the inner wall of the roller 100, thereby internally supporting and fixing the roller 100. The first inner support assembly 21 and the second inner support assembly 22 can quickly clamp and fix rollers 100 of different inner diameters before testing, which helps to improve the versatility and flexibility of the roller concentricity detection device and improve the clamping and detection efficiency. Among them, the telescopic drive member 211 includes but is not limited to a drive motor, a pneumatic motor or a hydraulic motor, which is not limited here.

[0055] like Figure 1 As shown, in some optional embodiments, the roller concentricity detection device further includes a fixed support 6 and a sliding support 7 arranged opposite to each other, the fixed support 6 being fixedly connected to the base plate 1, and the sliding support 7 being slidably connected to the base plate 1 in a direction approaching or moving away from the fixed support 6, the first drive assembly 3 being arranged on the fixed support 6, and the output end of the first drive assembly 3 being transmission-connected to the first inner support assembly 21, the second inner support assembly 22 being rotatably mounted on the sliding support 7, the first drive assembly 3 driving the first inner support assembly 21 to drive the roller 100 to rotate, and the second inner support assembly 22 rotating along with the roller 100. By moving the sliding support 7 in a direction approaching or moving away from the fixed support 6 to slide, the distance between the first inner support assembly 21 and the second inner support assembly 22 can be adjusted, so that rollers 100 of different lengths can be clamped and fixed, further improving the versatility and flexibility of the roller concentricity detection device and improving the clamping and detection efficiency.

[0056] In addition, the clamping mechanism 2 also includes a mounting rod 23, one end of the mounting rod 23 passes through the spline shaft 44, and one end is fixedly connected to the mounting frame 43, and the other end is rotatably connected to the second inner support assembly 22, so that the second inner support assembly 22 can rotate with the roller 100, avoiding torsional damage caused by inconsistent rotation at both ends when the roller 100 rotates around its own axis, thereby avoiding damage to the roller 100.

[0057] Furthermore, the roller concentricity detection device also includes a second drive component 8, which is arranged on the sliding support 7, and its output end is connected to the base plate 1 for driving the sliding support 7 to move in the direction close to or away from the fixed support 6. By adjusting the distance between the sliding support 7 and the fixed support 6 through the second drive component 8, the degree of automation of the concentricity detection of the roller 100 is further improved, and fast and accurate displacement control is achieved, which greatly shortens the preparation time of the detection equipment in different detection scenarios. It is particularly suitable for batch detection of different lengths, making the detection process smoother and more efficient, and the second drive component 8 ensures the stability of the sliding support 7 during movement through stable power output, which is conducive to ensuring the accuracy and reliability of the detection results. Optionally, the second drive component 8 includes but is not limited to the use of a linear guide motor, a pneumatic motor or a hydraulic motor, which is not limited here.

The sliding cooperation between the slide groove 9 and the slider 10 provides a guiding effect for the movement of the sliding support 7, which helps to ensure that the first inner support component 21 is coaxial with the second inner support component 22, thereby improving the accuracy of clamping and detection.

[0059] In other optional embodiments, the driven roller 33 is adjustably connected to the fixed support 6 in the vertical direction, and the mounting frame 43 is adjustably connected to the sliding bracket 521 in the vertical direction. For rollers 100 to be tested with different outer diameters, the staff can adjust the height of the first inner support assembly 21 and the second inner support assembly 22 from the base plate 1 by adjusting the position of the driven roller 33 and the mounting frame 43 in the vertical direction, thereby providing installation space for the roller 100 and avoiding interference with the base plate 1 or the support, further improving the versatility and flexibility of the roller concentricity detection device and improving the clamping and detection efficiency.
