Description

Technical Field

[0001] The invention belongs to the technical field of polyurethane roller detection, in particular to a polyurethane roller coaxiality detection device. Background Art

[0002] Polyurethane rollers are manufactured by pouring polyurethane onto the outer surface of the wheel core. Due to operational and mold factors during the manufacturing process, there may be a certain degree of coaxiality error between the outer surface of the polyurethane layer of the roller and the wheel core hole. During operation, this coaxiality error can affect the normal operation of the equipment and cause vibration, especially in high-speed applications. Therefore, coaxiality testing of polyurethane rollers is necessary.

[0003] Generally, the roller is cylindrical as a whole, so when the roller is rotated, only its side parts can be scanned and inspected. However, polyurethane rollers need to be chamfered and polished after production. Although the overall shape is approximately cylindrical, the ends near both ends are chamfered. At this time, only scanning and inspecting the side parts cannot determine whether there are eccentric protrusions at the ends, so the inspection tool needs to be improved. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems thereof by adopting the following technical solutions: a polyurethane roller coaxiality detection device, comprising a scanning device, a twisting device is provided at the bottom of the scanning device, and a detection roller is provided at the axis center of the upper surface of the twisting device;

[0005] The scanning device includes an anchoring top plate, a telescopic push cylinder is fixedly connected to the axis of the lower surface of the anchoring top plate, the bottom end of the telescopic push cylinder is fixedly connected to a sleeve guide cylinder, the sleeve guide cylinder is a hollow cylinder structure, and is used to sleeve the rod body of the lower axis. The bottom end of the sleeve guide cylinder is fixedly connected to a cluster chassis, and an axis opening for passing the rod body is opened at the axis of the cluster chassis to ensure that the cluster chassis can slide along the outer surface of the lower rod. The lower surface of the cluster chassis is evenly provided with searchlight equipment, and the inner cavity of the cluster chassis is evenly provided with horizontal scanning rods.

[0006] The searchlight equipment includes a fixed plate, and a guide wheel is symmetrically provided on the lower surface of the fixed plate through a fixed rod. The middle part of the outer surface of the guide wheel is rotatably connected to a propulsion slide, and a bending connecting rod is slidably connected to the axis of the inner wall of the propulsion slide. The bottom end of the bending connecting rod is fixedly connected to a scanning housing. The propulsion slide can drive the scanning housing in a horizontal state below to an oblique offset state by actively pushing the bending connecting rod. The lower surface of the scanning housing is fixedly connected to a light lens.

[0007] The torsion device includes a fixed chassis, the lower surface of which is fixedly connected to the ground. A drainage inner disk is fixedly connected to the inner cavity of the fixed chassis. A rotating module is disposed at the axis of the inner cavity of the fixed chassis. A sliding device is disposed on the upper surface of the fixed chassis. The detection roller is sleeved on the vertical rod of the rotating module. To ensure that the detection roller does not get stuck, the vertical rod of the rotating module is usually thin. The top of the anchoring top plate is fixedly connected to the ceiling. The top end of the rotating module is plugged into the axis of the inner cavity of the cluster chassis through the shaft opening. There are four searchlight devices, and the upper surface of the fixed plate is fixedly connected to the lower surface of the cluster chassis.

[0008] The rotary module includes a drainage base, a rotary motor fixedly connected to the axis of the inner cavity of the drainage base, a connecting shaft fixedly connected to the outer surface of the output shaft of the rotary motor, a plug-in top cover fixedly connected to the top of the connecting shaft, and an outer rotating drum fixedly connected to the bottom of the plug-in top cover via a plug. The inner cavity of the outer rotating drum is uniformly provided with through grooves, and the inner wall of the outer rotating drum is uniformly provided with inner sliding push plates through the through grooves. Compression spring bands are symmetrically provided on both sides of the outer surface of the inner sliding push plates, and the end of the compression spring band away from the inner sliding push plates is fixedly connected to the inner wall of the outer rotating drum. The drainage inner disk can pressurize the interior of the drainage base, and the pressure is applied to the interior of the outer rotating drum through the nozzle at the top of the rotary motor, thereby pushing the inner sliding push plates outward. The bottom end of the outer rotating drum is rotatably connected to the upper surface of the rotating motor, the outer surface of the drainage base is fixedly connected to the axis of the inner cavity of the fixed chassis, the outer surface of the connecting shaft is slidably connected to the inner wall of the inner sliding push plate through a guide groove, and the outer surface of the inner sliding push plate extends to the outside of the outer rotating drum.

[0009] The sliding device includes a filling disc, the inner cavity of which is uniformly provided with inlay grooves, and the inner cavity of which is uniformly provided with ball rotors through the inlay grooves. The outer side of the filling disc is uniformly provided with segmented pull rods through the through openings, the top of the segmented pull rods is fixedly connected to a control crane, and the upper surface of the control crane is fixedly connected to an anchor rod. The outer surface of the ball rotor is rollingly connected to the inner cavity of the filling disc through the inlay grooves, and the outer surface of the ball rotor extends to the outside of the filling disc. The bottom end of the segmented pull rod is fixedly connected to the inner cavity of the filling disc, and there are four anchor rods. The bottom end of the anchor rod is fixedly connected to the upper surface of the fixed chassis, the side surface of the filling disc is slidingly connected to the axis of the inner cavity of the fixed chassis, and the axis of the inner wall of the filling disc is slidingly connected to the outer surface of the outer rotating drum.

[0010] The beneficial effects of the present invention are as follows:

[0011] 1. The device can drive the sleeved detection roller to rotate centrifugally, so that the detection roller is in a high-speed rotation state, and then monitor the detection roller through the light lens directly above to observe whether there is shaking or jumping of the detection roller, and then judge the coaxiality of the detection roller to obtain a good detection roller. Since the light lens used for monitoring can be deflected as the push slide is adjusted, the light lens can face the end arc surface and chamfered part of the detection roller, and monitor the visual blind area of this part to judge whether there is an eccentric protrusion at its end.

[0012] 2. Since the scanning housing needs to be reset after the deflection adjustment, the horizontal scanning rods in the vertical state on all sides will be used as anchor rods to correct the horizontal state of the scanning housing and avoid the problem of deflection caused by improper resetting of the scanning housing. At the same time, the cluster chassis can pass through the rotating module rod at the bottom, so that the searchlight equipment can maintain an appropriate distance from the detection roller, making the sampling image clearer.

[0013] 3. Since the detection roller is sleeved on the outer drum and rotates, the top and upper area of the outer drum will be inserted by the scanning device. Therefore, the detection roller will not be thrown off the outer surface of the outer drum during high-speed centrifugal rotation, and the extrusion pressure between each inner sliding push plate and the inner wall of the detection roller will not be too large. While ensuring that the outer drum can adapt to detection rollers of a certain size, it can also avoid the problem of severe extrusion deformation of the inner wall when tightening the detection roller.

[0014] 4. After the detection roller is sleeved on the outer surface of the outer drum, its bottom will rotate relative to the ball rotor, thereby effectively reducing the problem of wear on the bottom of the detection roller. At the same time, the filling disc can be lifted in the vertical direction by controlling the crane to pull the segmented pull rod. At this time, the squeezing and fixing effect of the inner sliding push plate on the detection roller is weakened, so that the filling disc drives the detection roller to rise, and then reaches a certain height, and then the detection roller is tightened to rotate, thereby measuring the rotation status of the detection roller at different heights, eliminating the system error caused by the device as much as possible, and improving the accuracy of the detection results.

[0024] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0025] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a polyurethane roller coaxiality detection device, comprising a scanning device 1, a twisting device 2 is provided at the bottom of the scanning device 1, and a detection roller 3 is provided at the axis center of the upper surface of the twisting device 2;

[0026] The scanning device 1 includes an anchoring top plate 11, a telescopic push cylinder 12 is fixedly connected to the axis of the lower surface of the anchoring top plate 11, the bottom end of the telescopic push cylinder 12 is fixedly connected to a sleeve guide cylinder 13, the sleeve guide cylinder 13 is a hollow cylindrical structure, which is used to sleeve the rod body of the lower axis, and the bottom end of the sleeve guide cylinder 13 is fixedly connected to a cluster chassis 14, the axis of the cluster chassis 14 is provided with an axial opening for passing through the rod body, ensuring that the cluster chassis 14 can slide along the outer surface of the lower rod, the lower surface of the cluster chassis 14 is evenly provided with searchlight devices 5, and the inner cavity of the cluster chassis 14 is evenly provided with horizontal scanning rods 15;

[0027] The searchlight device 5 includes a fixed plate 51, and a guide wheel 52 is symmetrically arranged on the lower surface of the fixed plate 51 through a fixed rod. The middle part of the outer surface of the guide wheel 52 is rotatably connected to a propulsion slide 53, and a bending link 54 is slidably connected to the axis of the inner wall of the propulsion slide 53. The bottom end of the bending link 54 is fixedly connected to a scanning housing 55. The propulsion slide 53 can drive the scanning housing 55 in a horizontal state below to an oblique offset state by actively pushing the bending link 54. The lower surface of the scanning housing 55 is fixedly connected to a light lens 56.

[0028] The torsion device 2 includes a fixed chassis 21, the lower surface of which is fixedly connected to the ground. A drainage inner disk 23 is fixedly connected to the inner cavity of the fixed chassis 21. A rotating module 4 is provided at the axis of the inner cavity of the fixed chassis 21. A sliding device 22 is provided on the upper surface of the fixed chassis 21. The detection roller 3 is sleeved on the vertical rod of the rotating module 4. To ensure that the detection roller 3 does not get stuck, the vertical rod of the rotating module 4 is usually thin. The top of the anchoring top plate 11 is fixedly connected to the ceiling. The top of the rotating module 4 is plugged into the axis of the inner cavity of the cluster chassis 14 through the shaft opening. There are four searchlight devices 5, and the upper surface of the fixed plate 51 is fixedly connected to the lower surface of the cluster chassis 14.

[0029] When using this device to detect the coaxiality of the roller, the detection roller 3 is placed on the twisting device 2, and then the scanning device 1 above pushes its telescopic push cylinder 12 downward, so that the cluster chassis 14 passes through the rotating module 4, and the searchlight device 5 is also gradually pushed to the side of the detection roller 3.

[0030] After reaching a certain safe height from the detection roller 3, the telescopic push cylinder 12 stops its propulsion movement. At this time, the rotating module 4 drives the detection roller 3 to rotate on its own, and then the searchlight device 5 performs a top-down scanning and detection operation on the rotating detection roller 3. If the detection roller 3 has an irregular shape, or shakes or is eccentric during rotation, the scanning housing 55 will determine the eccentricity of the detection roller 3 through the light lens 56 at the bottom, and then detect a defective detection roller 3.

[0031] When the scanning housing 55 performs vertical scanning from top to bottom through the light lens 56, the propulsion slide 53 of each searchlight device 5 also controls the corresponding bending link 54 to perform telescopic movement, that is, the propulsion slide 53 away from the rotating module 4 pushes the bending link 54 downward, and the propulsion slide 53 close to the rotating module 4 retracts the bending link 54 upward, thereby causing the scanning housing 55 to be obliquely offset toward the side close to the detection roller 3, so that the light lens 56 of the vertical fixed chassis 21 is deflected toward the side direction of the detection roller 3, thereby performing scanning work, and then judging whether an eccentric protrusion appears at the end of the detection roller 3 based on whether the end of the detection roller 3 shakes or moves eccentrically.

[0032] After each comprehensive inspection of the inspection roller 3, in the process of retracting the beam collecting chassis 14, the pushing slide 53 will pull the bending connecting rod 54 back to the initial horizontal position. Through the horizontal scanning work of each horizontal scanning rod 15, it can be determined whether the scanning housing 55 and the light lens 56 are in a horizontal state, and then fine-tuning can be performed to ensure that the searchlight equipment 5 can be perfectly reset.

[0033] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: Based on Example 1, a rotary module 4 includes a drainage base 41. A rotary motor 42 is fixedly connected to the axis of the inner cavity of the drainage base 41. A connecting shaft 43 is fixedly connected to the outer surface of the output shaft of the rotary motor 42. A plug-in top cover 44 is fixedly connected to the top of the connecting shaft 43. The bottom of the plug-in top cover 44 is fixedly connected to an outer rotating cylinder 45 via a plug. The inner cavity of the outer rotating cylinder 45 is uniformly provided with through-grooves. Inner sliding push plates 46 are uniformly provided on the inner wall of the outer rotating cylinder 45 through the through-grooves. Compression spring bands 47 are symmetrically provided on both sides of the outer surface of the inner sliding push plates 46. The end of the compression spring band 47 away from the inner sliding push plates 46 is fixedly connected to the inner wall of the outer rotating cylinder 45. The drainage inner disk 23 can pressurize the interior of the drainage base 41. The pressure is applied to the interior of the outer rotating cylinder 45 through the nozzle at the top of the rotary motor 42, thereby pushing the inner sliding push plates 46 outward. The bottom end of the outer rotating drum 45 is rotatably connected to the upper surface of the rotating motor 42, the outer surface of the drainage base 41 is fixedly connected to the axis center of the inner cavity of the fixed chassis 21, the outer surface of the connecting shaft 43 is slidably connected to the inner wall of the inner sliding push plate 46 through a guide groove, and the outer surface of the inner sliding push plate 46 extends to the outside of the outer rotating drum 45.

[0034] The sliding device 22 includes a filling disc 221. The inner cavity of the filling disc 221 is uniformly provided with inlay grooves. Ball rotors 222 are evenly distributed throughout the inner cavity of the filling disc 221 through the inlay grooves. Segmented pull rods 223 are evenly distributed through the outer side of the filling disc 221 through openings. The top ends of the segmented pull rods 223 are fixedly connected to control cranes 224, and the upper surfaces of the control cranes 224 are fixedly connected to anchor rods 225. The outer surfaces of the ball rotors 222 are in rolling contact with the inner cavity of the filling disc 221 through the inlay grooves and extend to the exterior of the filling disc 221. The bottom ends of the segmented pull rods 223 are fixedly connected to the inner cavity of the filling disc 221. There are four anchor rods 225. The bottom end of the anchor rod 225 is fixedly connected to the upper surface of the fixed chassis 21, the side of the filling disc 221 is slidably connected to the axis of the inner cavity of the fixed chassis 21, and the axis of the inner wall of the filling disc 221 is slidably connected to the outer surface of the outer rotating cylinder 45.

[0035] When the detection roller 3 is sleeved on the bottom of the outer surface of the outer rotating cylinder 45, the drainage inner disk 23 will pressurize the inside of the outer rotating cylinder 45 through the drainage base 41, so that each inner sliding push plate 46 is pushed toward the outside of the outer rotating cylinder 45, and then the inner wall of the detection roller 3 is pressed by the convex inner sliding push plate 46, thereby squeezing the inner wall of the detection roller 3 and achieving the effect of fixing the detection roller 3. The rotating motor 42 drives the outer rotating cylinder 45 to rotate at high speed by twisting the connecting shaft 43, thereby driving the detection roller 3 to rotate.

[0036] After the detection roller 3 is sleeved on the outer surface of the outer rotating cylinder 45, its bottom will rotate relative to the ball rotor 222, thereby effectively reducing the problem of wear on the bottom of the detection roller 3. At the same time, the filling disc 221 can be lifted in the vertical direction by controlling the crane 224 to pull the segmented pull rod 223. At this time, the squeezing and fixing effect of the inner sliding push plate 46 on the detection roller 3 is weakened, so that the filling disc 221 drives the detection roller 3 to rise, and then reaches a certain height, and then the detection roller 3 is tightened to rotate, thereby measuring the rotation status of the detection roller 3 at different heights, and eliminating the system error generated by the device as much as possible.

[0037] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
