Description

Technical Field

[0001] This invention relates to the field of roller concentricity detection technology, and in particular to a roller concentricity detection device. Background Technology

[0002] In the hot stamping process, the roller is a key component, and its concentricity plays a decisive role in product processing accuracy and production efficiency. Roller concentricity characterizes the offset between the roller's axis and the rotation axis during rotation. This parameter directly affects core indicators such as the uniformity of pressure distribution and the clarity of the stamped pattern during hot stamping. Poor roller concentricity not only leads to an increased product scrap rate but also increases equipment wear and tear and reduces production efficiency. Therefore, the accuracy of roller concentricity detection is crucial.

[0003] Most existing concentricity testing devices adopt a single-point testing method, which can only detect the concentricity of the roller at specified positions along its axial and circumferential directions. This testing method has significant drawbacks: since the concentricity of the roller may vary at different positions along the axial and circumferential directions during actual operation, the test results at a specific position cannot fully reflect the overall concentricity of the roller, resulting in unrepresentative test data that cannot meet the requirements of high-precision production. Furthermore, when testing different positions, the position of the testing device needs to be adjusted, which is complex and inefficient.

[0004] Therefore, there is an urgent need to propose a device and method for detecting the concentricity of rollers in order to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a roller concentricity detection device to achieve overall and comprehensive detection of roller concentricity, improve detection accuracy and efficiency, thereby effectively improving the quality of hot stamping process, reducing product scrap rate, increasing production efficiency, reducing equipment wear and tear, and meeting the stringent requirements of high-precision production in modern hot stamping processes.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A roller concentricity detection device includes a base plate, a clamping mechanism, a first driving assembly, a transmission mechanism, and a detection mechanism. The clamping mechanism is used to clamp the roller. The first driving assembly is disposed on the base plate and its output end is drivenly connected to the clamping mechanism to drive the clamping mechanism to rotate the roller around its axis. The detection mechanism is used to detect the concentricity of the roller surface, and the transmission mechanism is drivenly connected between the detection mechanism and the output end of the first driving assembly.

[0008] When the first driving component drives the clamping mechanism to rotate the roller around its axis, the transmission mechanism is configured to drive the detection mechanism to move intermittently along the axial direction of the roller and around the circumference of the roller.

[0009] Furthermore, the first driving assembly includes a driving member, a driving roller, a driven roller, and a transmission belt. The driving roller and the driven roller are arranged parallel to each other and spaced apart along the radial direction of the roller. The clamping mechanism is connected to the driven roller. The driving roller and the driven roller together tension the transmission belt. The output end of the driving member is connected to the driving roller to drive the driving roller to rotate.

[0010] Furthermore, the transmission mechanism includes a transmission rod, a first transmission gear, a mounting frame, a spline shaft, a spline sleeve, a second transmission gear, and a transmission cylinder assembly. One end of the transmission rod is coaxially connected to the drive roller, and the other end is provided with the first transmission gear. The second transmission gear is rotatably mounted on the mounting frame. The spline shaft is coaxially connected to the second transmission gear. The spline sleeve is splinedly connected to the spline shaft, and the detection mechanism is connected to the spline sleeve. The transmission cylinder assembly is tractively connected between the first transmission gear, the second transmission gear, and the spline sleeve, and is used to drive the second transmission gear to rotate or drive the spline sleeve to move along the axial direction of the roller, thereby causing the detection mechanism on the spline sleeve to move alternately and intermittently along the axial direction of the roller and around the circumference of the roller.

[0011] Furthermore, the transmission cylinder assembly includes a transmission cylinder, a transmission disc, and a transmission component. The transmission disc is coaxially connected to one end of the transmission cylinder. The transmission disc has multiple arc-shaped teeth circumferentially for meshing with the first transmission gear. One end of the transmission cylinder has multiple spaced tooth blocks for meshing with the second transmission gear. The circumferential surface of the transmission cylinder also has a transmission groove, which is formed by connecting horizontal grooves and inclined grooves end to end in sequence. The tooth blocks correspond to the horizontal groove of the transmission groove. The spline sleeve has a limiting ring with a limiting groove on its surface. One end of the transmission component is pinned to the mounting frame, and the other end is slidably connected to the transmission groove and the limiting groove on both sides, respectively.

[0012] Furthermore, the detection mechanism includes an adjustment component and a detection component mounted on the adjustment component. The detection end of the detection component is configured to abut against the roller surface of the roller, and the adjustment component is configured to adjust the distance between the detection end of the detection component and the axis of the roller.

[0013] Further, the detection assembly includes a bracket and at least two form and position tolerance measuring gauges mounted on the bracket, wherein the at least two form and position tolerance measuring gauges are spaced apart along the axial direction of the roller, and the detection end of the form and position tolerance measuring gauge abuts against the roller surface of the roller; and / or,

[0014] The testing mechanism includes a testing frame, a pressure testing element, a testing lever, and an elastic element. The pressure testing element is disposed on the testing frame, the testing lever is pinned to the testing frame, and the elastic element is disposed between one end of the testing lever and the pressure testing element, while the other end can abut against the roller surface of the roller.

[0015] Furthermore, the adjusting assembly includes an adjusting frame, a screw sleeve, and a screw rod. The screw rod is rotatably connected to the adjusting frame and extends radially along the roller. The screw sleeve is threadedly connected to the screw rod and slidably connected to the adjusting frame along the extension direction of the screw rod. The detection assembly is connected to the screw sleeve.

[0016] Furthermore, the clamping mechanism includes a first inner support assembly and a second inner support assembly arranged coaxially and oppositely. The first inner support assembly and the second inner support assembly are respectively used to internally support and fix the two ends of the roller. Each of the first inner support assembly and the second inner support assembly includes a telescopic drive component, a support column, a fixed ring, a movable ring, a plurality of first support rods, and second support rods, mounting strips, and inner support components corresponding to the first support rods. The fixed ring is fixedly sleeved on the support column, and the movable ring is slidably sleeved on the support column. The fixed ring is circumferentially pinned to a plurality of first support rods, and the movable ring is circumferentially pinned to a corresponding second support rod. The two ends of the mounting strip are pinned to the corresponding first support rods and second support rods, respectively. Each mounting strip is equipped with an inner support component. The output end of the telescopic drive component is drivenly connected to the movable ring to drive the movable ring closer to or away from the fixed ring, thereby adjusting the distance between the inner support component and the axis of the support column.

[0017] Furthermore, the roller concentricity detection device also includes a fixed support and a sliding support arranged opposite to each other. The fixed support is fixedly connected to the base plate, and the sliding support is slidably connected to the base plate in a direction close to or away from the fixed support. The first driving component is disposed on the fixed support, and the output end of the first driving component is drivenly connected to the first inner support component. The second inner support component is rotatably mounted on the sliding support.

[0018] Furthermore, the roller concentricity detection device also includes a second drive assembly, which is disposed on the sliding support and its output end is connected to the base plate for driving the sliding support to move in a direction closer to or away from the fixed support.

[0019] The beneficial effects of this invention are:

[0020] This invention provides a roller concentricity detection device, including a base plate, a clamping mechanism, a drive assembly, a transmission mechanism, and a detection mechanism. The clamping mechanism is used to clamp the roller. The drive assembly is mounted on the base plate, and its output end is connected to the clamping mechanism for driving the clamping mechanism to rotate the roller around its axis. The detection mechanism is used to detect the concentricity of the roller surface, and a transmission mechanism is connected between the detection mechanism and the output end of the drive assembly. When the drive assembly drives the clamping mechanism to rotate the roller around its axis, the transmission mechanism is configured to drive the detection mechanism to alternately and intermittently move along the roller's axial direction and around its circumference. This allows the detection mechanism to sequentially switch between acting on different positions along the roller's axial and circumferential directions in a dynamic feed trajectory, providing high coverage, multi-area, and automated measurement on the roller surface. This achieves comprehensive and holistic detection of the roller's concentricity, improving detection accuracy and efficiency, thereby effectively improving the quality of hot stamping processes, reducing product scrap rates, increasing production efficiency, reducing equipment wear, and meeting the stringent requirements of high-precision production in modern hot stamping processes.

[0037] The present invention will now be described in further detail 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 not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[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 driving assembly 3, a transmission mechanism 4, and a detection mechanism 5. The clamping mechanism 2 is used to clamp the roller 100. The first driving assembly 3 is disposed on the base plate 1, and its output end is drivenly connected to the clamping mechanism 2, used to drive the clamping mechanism 2 to rotate the roller 100 around its axis. The detection mechanism 5 is used to detect the concentricity of the roller surface of the roller 100, and a transmission mechanism 4 is drivenly connected between the detection mechanism 5 and the output end of the first driving assembly 3. When the first driving assembly 3 drives the clamping mechanism 2 to rotate the roller 100 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. This causes the detection component 52 to switch and act on different positions in the axial and circumferential directions of the roller in a dynamic feed trajectory manner. It acts on the surface of the roller body in a high-coverage, multi-area, and automated measurement manner to achieve overall and comprehensive detection of the concentricity of the roller 100. This can improve detection accuracy and efficiency, thereby effectively improving the quality of hot stamping process, reducing product scrap rate, increasing production efficiency, reducing equipment wear, and meeting the strict requirements of high-precision production in modern hot stamping process.

[0042] The first drive assembly 3 includes a drive element 31, a drive roller 32, a driven roller 33, and a transmission belt 34. The drive roller 32 and the driven roller 33 are arranged parallel to each other and spaced apart along the radial direction of the roller 100. The clamping mechanism 2 is connected to the driven roller 33. The drive roller 32 and the driven roller 33 together tension the transmission belt 34. The output end of the drive element 31 is connected to the drive roller 32 to drive the drive roller 32 to rotate, thereby driving the clamping mechanism 2 to rotate, and thus driving the roller 100 to be measured to rotate. This is beneficial to improving the automation level of concentricity detection, thereby improving detection efficiency. Optionally, the drive element 31 may include, but is not limited to, a drive motor, a pneumatic motor, or a hydraulic motor, and 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 drive roller 32, and the other end is provided with the first transmission gear 42. The second transmission gear 46 is rotatably mounted on the mounting frame 43. The spline shaft 44 is coaxially connected to the second transmission gear 46. The spline sleeve 45 is splinedly connected to the spline shaft 44, and the detection mechanism 5 is connected to the spline sleeve 45. The transmission cylinder assembly 47 is tractively connected between the first transmission gear 42, 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 along the axial direction of 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 1-5 As shown, specifically, the transmission cylinder assembly 47 includes a transmission cylinder 471, a transmission disc 472, and a transmission component 473. The transmission disc 472 is coaxially connected to one end of the transmission cylinder 471. The transmission disc 472 has multiple arc-shaped teeth 4721 circumferentially arranged for meshing with the first transmission gear 42. One end of the transmission cylinder 471 has multiple spaced tooth blocks 474 arranged around it for meshing with the second transmission gear 46. The circumferential surface of the transmission cylinder 471 also has a transmission groove 475, which is formed by horizontal grooves and inclined grooves connected end to end in sequence. The tooth blocks 474 correspond to the horizontal grooves of the transmission groove 475. The spline sleeve 45 has a limiting ring 451, and the surface of the limiting ring 451 has a limiting groove. One end of the transmission component 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 respectively. When the tooth blocks 474 mesh with the second transmission gear 46, the transmission component... 473 is slidably connected in the horizontal groove. At this time, the position of the transmission component 473 along the axial direction of the roller 100 remains unchanged, while the tooth block 474 interacts with the second transmission gear 46, driving 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 at a certain angle; when the interval between adjacent tooth blocks 474 acts on the second transmission gear 46, the first transmission gear 42 stops rotating. At this time, the transmission component 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 the axial direction of the spline shaft 44; this cycle repeats. When the transmission cylinder 471 rotates once, it can drive the detection component 52 to move alternately and intermittently along the axial direction of the roller 100 and around the circumference of the roller 100, forming a stepped stepping point switching detection mode on the roller surface of the roller 100.

[0045] The transmission cylinder assembly 47 also includes a rotating shaft 476, on which a transmission cylinder 471 and a transmission disc 472 are coaxially connected. The rotating shaft 476 is rotatably connected to the mounting frame 43, providing a reliable support foundation for the transmission cylinder 471 and the transmission disc 472. This greatly enhances the stability of the rotatable connection between the transmission cylinder assembly 47 and the mounting frame 43, and improves transmission accuracy and efficiency.

[0046] like Figure 5As shown, the transmission component 473 includes a first connecting rod 4731, a second connecting rod 4732, a third connecting rod 4733, and a limiting post. The mounting frame 43 is provided with a mounting block 431, which is located between the transmission cylinder 471 and the spline sleeve 45. The first connecting rod 4731 and the second connecting rod 4732 are pinned to 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 to 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 limiting posts. The limiting posts are engaged 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 adjustment component 51 and a detection component 52 mounted on the adjustment component 51. The detection end of the detection component 52 is configured to abut against the roller surface of the roller 100, thereby detecting the concentricity of the abutment position during the rotation of the roller 100 around its axis. The adjustment component 51 is configured to adjust the distance between the detection end of the detection component 52 and the axis of the roller 100, which can adapt to the detection requirements of rollers 100 with different diameters, improve the versatility and flexibility of the roller concentricity detection device, thereby reducing detection costs and improving detection efficiency.

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

[0049] Optionally, the detection mechanism 5 also includes a detection frame 523, a pressure detection element 524, a detection lever 525, and an elastic element 526. The pressure detection element 524 is mounted on the detection frame 523, and the detection lever 525 is pinned to the detection frame 523. One end of the detection lever 525 is connected to the pressure detection element 524 with the elastic element 526, and the other end can abut against the roller surface of the roller 100. 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 element 526, thereby causing the pressure detection element 524 to generate a pressure value. When detecting the concentricity of the roller 100, once there is a concentricity deviation in the roller 100, the pressure reading of the pressure detection element 524 will also change accordingly. By observing the fluctuation of the pressure reading of the pressure detection element 524, it is possible to quickly determine whether there is a concentricity deviation.

[0050] The pressure sensing element 524 includes, but is not limited to, strain gauge pressure sensors or piezoelectric pressure sensors, which are not specified here.

[0051] In this embodiment, the adjustment component 51 includes an adjustment frame 511, a screw sleeve 512, and a screw 513. The screw 513 is rotatably connected to the adjustment frame 511 and extends radially along the roller 100. The screw sleeve 512 is threadedly connected to the screw 513. The detection component 52 is connected to the screw sleeve 512, and the screw sleeve 512 is slidably connected to the adjustment frame 511 along the extending direction of the screw 513. By rotating the screw 513, the screw sleeve 512 can be driven to move along the extending direction of the screw 513, thereby adjusting the distance between the detection component 52 and the roller 100 and ensuring that the detection end of the detection component 52 abuts against the roller surface of the roller 100.

[0052] Furthermore, to facilitate the screw 513, a rod cap 515 is connected to the end of the screw 513 away from the roller 100. The rod cap 515 extends outside the adjustment frame 511 to facilitate the operator's screwing operation.

[0053] In this embodiment, the bracket 521 is connected to the threaded sleeve 512, and the inspection frame 523 is connected to the bracket 521 to realize the installation of the form and position tolerance measuring table 522, the pressure testing element 524, the inspection lever 525 and the elastic element 526.

[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 coaxially 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. Each of the first inner support assembly 21 and the second inner support assembly 22 includes a telescopic drive component 211, a support column 212, a fixed ring 213, a movable ring 214, multiple first support rods 215, and second support rods 216, mounting strips 217, and inner support components 218 corresponding to the first support rods 215. 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. Multiple first support rods 215 are circumferentially spaced and pinned to the fixed ring 213, and the movable ring 214... A second support rod 216 is pinned to the circumferentially connected. The two ends of the mounting strip 217 are pinned to the corresponding first support rod 215 and second support rod 216, respectively. Each mounting strip 217 is equipped with an inner support member 218. The output end of the telescopic drive member 211 is connected to the movable ring 214 for driving the movable ring 214 closer to or further from the fixed ring 213, thereby adjusting the distance between the inner support member 218 and the axis of the support column 212. This allows the inner support member to abut against the inner wall of the roller 100, providing internal support and fixation for the roller 100. The first inner support assembly 21 and the second inner support assembly 22 can quickly clamp and fix rollers 100 with different inner diameters before testing, helping to improve the versatility and flexibility of the roller concentricity detection device and increasing clamping and testing efficiency. The telescopic drive member 211 includes, but is not limited to, a drive motor, pneumatic motor, or hydraulic motor, and 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 disposed opposite to each other. The fixed support 6 is fixedly connected to the base plate 1, and the sliding support 7 is slidably connected to the base plate 1 in a direction close to or away from the fixed support 6. A first drive assembly 3 is disposed on the fixed support 6, and the output end of the first drive assembly 3 is drively connected to the first inner support assembly 21. A second inner support assembly 22 is rotatably mounted on the sliding support 7. The first drive assembly 3 drives the first inner support assembly 21 to drive the roller 100 to rotate, and the second inner support assembly 22 rotates with the roller 100. By moving the sliding support 7 in a direction close to or away from the fixed support 6 to adjust the distance between the first inner support assembly 21 and the second inner support assembly 22, rollers 100 of different lengths can be clamped and fixed, further improving the versatility and flexibility of the roller concentricity detection device and improving 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 is fixedly connected to the mounting frame 43. 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, thereby avoiding torque damage caused by the inconsistent rotation at both ends when the roller 100 rotates around its own axis, and thus avoiding damage to the roller 100.

[0057] Furthermore, the roller concentricity detection device also includes a second drive assembly 8, which is mounted on the sliding support 7 and its output end is connected to the base plate 1 for driving the sliding support 7 to move towards 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 assembly 8, the automation level of the roller 100 concentricity detection is further improved, achieving rapid and accurate displacement control. This significantly shortens the preparation time of the detection equipment in different detection scenarios, making it particularly suitable for batch detection of different lengths, resulting in a smoother and more efficient detection process. Moreover, the second drive assembly 8, through stable power output, ensures the stability of the sliding support 7 during movement, which helps guarantee the accuracy and reliability of the detection results. Optionally, the second drive assembly 8 may include, but is not limited to, a linear guide motor, a pneumatic motor, or a hydraulic motor; no limitation is made here.

[0058] Among them, one of the base plate 1 and the sliding support 7 is provided with a groove 9 extending in the direction close to or away from the fixed support 6, and the other is provided with a slider 10 slidably connected to the groove 9. The sliding cooperation between the groove 9 and the slider 10 provides guidance for the movement of the sliding support 7, which helps to ensure that the first inner support assembly 21 and the second inner support assembly 22 are coaxial, and improves the accuracy of clamping and detection.

[0059] In some alternative embodiments, the driven roller 33 is vertically adjustable to the fixed support 6, and the mounting frame 43 is vertically adjustable to the sliding bracket 521. For rollers 100 with different outer diameters, the operator 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 vertical positions of the driven roller 33 and the mounting frame 43, thereby providing installation space for the roller 100, avoiding interference with the base plate 1 or the support, and further improving the versatility and flexibility of the roller concentricity detection device, and improving clamping and detection efficiency.
