Description

Technical Field

[0001] This invention belongs to the field of polyurethane roller testing technology, specifically a polyurethane roller coaxiality testing device. Background Technology

[0002] Polyurethane rollers are made by casting polyurethane raw materials onto the outer circumference of the wheel core. Due to operational factors and mold factors during the manufacturing process, there will be a certain coaxiality error between the outer circumference of the polyurethane layer and the hole in the wheel core. During operation, the coaxiality error of the polyurethane roller will affect the normal operation of the equipment and generate vibration, especially when used in high-speed applications. Therefore, it is necessary to perform coaxiality testing on the polyurethane roller.

[0003] A typical roller is cylindrical, so when rotating it, only its side surface can be scanned for inspection. However, polyurethane rollers require chamfering and grinding after production. Although they are roughly cylindrical, they have chamfered ends. Therefore, scanning only the side surface cannot determine whether there are any eccentric protrusions at the ends. Thus, the inspection tool needs to be improved. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention to solve its technical problems is: a polyurethane roller coaxiality detection device, including a scanning device, a torsion device is provided at the bottom of the scanning device, and a detection roller is provided at the center of the upper surface of the torsion device;

[0005] The scanning device includes an anchoring top plate, a telescopic pusher is fixedly connected to the axis of the lower surface of the anchoring top plate, a sleeve guide tube is fixedly connected to the bottom end of the telescopic pusher, the sleeve guide tube is a hollow cylindrical structure used to sleeve the rod at the lower axis, a clustering base plate is fixedly connected to the bottom end of the sleeve guide tube, the clustering base plate has an axis opening at the axis for penetrating the rod, ensuring that the clustering base plate can slide along the outer surface of the lower rod, the lower surface of the clustering base plate is uniformly provided with detection devices, and the inner cavity of the clustering base plate is uniformly provided with horizontal scanning rods;

[0006] The detection device includes a fixed plate, and guide wheels are symmetrically arranged on the lower surface of the fixed plate via fixed rods. A propulsion slide is rotatably connected to the middle of the outer surface of the guide wheels. A bending connecting rod is slidably connected to the axis of the inner wall of the propulsion slide. A scanning housing is fixedly connected to the bottom end of the bending connecting rod. The propulsion slide can drive the horizontal scanning housing below to a skewed offset state by actively pushing the bending connecting rod. A light lens is fixedly connected to the lower surface of the scanning housing.

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

[0008] The rotating module includes a drainage base. A rotary motor is fixedly connected to the axis of the drainage base's inner cavity. A connecting shaft is fixedly connected to the outer surface of the rotary motor's output shaft. A plug-in top cover is fixedly connected to the top of the connecting shaft. An outer rotating cylinder is fixedly connected to the bottom of the plug-in top cover via a plug. The inner cavity of the outer rotating cylinder has uniformly spaced through-cut slots. Inner sliding push plates are uniformly arranged on the inner wall of the outer rotating cylinder through the through-cut slots. Compression spring bands are symmetrically arranged 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 plate is fixedly connected to the inner wall of the outer rotating cylinder. The drainage inner plate can pressurize the inside of the drainage base, and pressurize the inside of the outer rotating cylinder 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 cylinder 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 the guide groove, and the outer surface of the inner sliding push plate extends to the outside of the outer rotating cylinder.

[0009] The sliding device includes a filling disc with uniformly spaced indented grooves in its inner cavity. Ball bearing rotors are uniformly arranged within these grooves. Segmented tie rods are uniformly arranged on the outer side of the filling disc through through-holes. A control crane is fixedly connected to the top of each tie rod, and anchor rods are fixedly connected to the upper surface of the control crane. The outer surface of the ball bearing rotors is in rolling contact with the inner cavity of the filling disc through the indented grooves, and extends beyond the outer surface of the filling disc. The bottom ends of the segmented tie rods are fixedly connected to the inner cavity of the filling disc. There are four anchor rods. The bottom ends of the anchor rods are fixedly connected to the upper surface of a fixed base. The side of the filling disc is slidably connected to the axis of the inner cavity of the fixed base, and the axis of the inner wall of the filling disc is slidably connected to the outer surface of the outer rotating cylinder.

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

[0011] 1. This device can drive the sleeved detection roller to rotate centrifugally, thus putting the detection roller in a high-speed rotation state. Then, the light lens directly above monitors whether the detection roller shakes or jumps, thereby judging the coaxiality of the detection roller and obtaining a good detection roller. Since the light lens used for monitoring can be tilted as the push slide is adjusted, the light lens can be directly aimed at the end arc surface and chamfer of the detection roller to monitor this visual blind spot and judge whether there is an eccentric protrusion at the end.

[0012] 2. Since the scanning housing needs to be reset after the tilt adjustment, the horizontal scanning rods in a vertical position around the perimeter are used as anchor rods to correct the horizontal state of the scanning housing and avoid the problem of tilting due to improper reset of the scanning housing. At the same time, the cluster chassis can pass through the rotating module rod at the bottom, so that the detection equipment can maintain a proper distance from the detection roller, making the sampling image clearer.

[0013] 3. Since the detection roller is sleeved on the outer rotating cylinder and rotates, the top and upper areas of the outer rotating cylinder will be inserted by the scanning device. Therefore, the detection roller will not be flung off the outer surface of the outer rotating cylinder when it rotates at high speed. The squeezing force between each inner sliding plate and the inner wall of the detection roller will not be too large. While ensuring that the outer rotating cylinder can accommodate detection rollers of a certain size, it can also avoid the serious squeezing deformation problem caused to the inner wall when tightening the detection roller.

[0014] 4. After the detection roller is fitted onto the outer surface of the outer rotating cylinder, its bottom will rotate relative to the ball rotor, effectively reducing the wear on the bottom of the detection roller. At the same time, the filling disc can be lifted vertically by controlling the crane to pull the segmented tie rod. At this time, the squeezing and fixing effect of the inner sliding push plate on the detection roller is weakened, which causes the filling disc to drive the detection roller to rise. After reaching a certain height, the detection roller is tightened and rotated, thereby measuring the rotation status of the detection roller at different heights, minimizing systematic errors caused by the device, and improving the accuracy of the test results.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0025] Example 1, please refer to Figures 1-5 The present invention provides a technical solution: a polyurethane roller coaxiality detection device, including a scanning device 1, a torsion device 2 at the bottom of the scanning device 1, and a detection roller 3 at the center of the upper surface of the torsion device 2.

[0026] The scanning device 1 includes an anchoring top plate 11. A telescopic pusher 12 is fixedly connected to the axis of the lower surface of the anchoring top plate 11. A sleeve guide 13 is fixedly connected to the bottom end of the telescopic pusher 12. The sleeve guide 13 is a hollow cylindrical structure used to sleeve the rod at the lower axis. A clustering base 14 is fixedly connected to the bottom end of the sleeve guide 13. A central opening for penetrating the rod is opened at the axis of the clustering base 14 to ensure that the clustering base 14 can slide along the outer surface of the lower rod. Illumination devices 5 are evenly arranged on the lower surface of the clustering base 14. Horizontal scanning rods 15 are evenly arranged in the inner cavity of the clustering base 14.

[0027] The illumination device 5 includes a fixed plate 51. Guide wheels 52 are symmetrically arranged on the lower surface of the fixed plate 51 via fixed rods. A propulsion slide 53 is rotatably connected to the middle of the outer surface of the guide wheels 52. A bending connecting rod 54 is slidably connected at the axis of the inner wall of the propulsion slide 53. A scanning housing 55 is fixedly connected to the bottom end of the bending connecting rod 54. The propulsion slide 53 can drive the horizontal scanning housing 55 below to a skewed offset state by actively pushing the bending connecting rod 54. A light lens 56 is fixedly connected to the lower surface of the scanning housing 55.

[0028] The torsion device 2 includes a fixed base 21, the lower surface of which is fixedly connected to the ground. A drainage inner plate 23 is fixedly connected to the inner cavity of the fixed base 21. A rotating module 4 is positioned at the axis of the inner cavity of the fixed base 21. A sliding device 22 is positioned on the upper surface of the fixed base 21. A 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 typically thin. The top of the anchoring top plate 11 is fixedly connected to the ceiling. The top of the rotating module 4 is inserted into the axis of the inner cavity of the clustering base 14 through a shaft opening. There are four detection devices 5. The upper surface of the fixing plate 51 is fixedly connected to the lower surface of the clustering base 14.

[0029] When using this device to test the coaxiality of the rollers, the test roller 3 is placed on the torsion device 2, and then the scanning device 1 above pushes its telescopic pusher 12 downward, so that the cluster base 14 passes through the rotating module 4, and the probe device 5 is also gradually pushed to one side of the test roller 3.

[0030] After reaching a certain safe height from the detection roller 3, the telescopic pusher 12 stops its forward movement. At this time, the rotating module 4 drives the detection roller 3 to rotate. Then, the scanning device 5 performs a top-down scanning inspection on the rotating detection roller 3. If the detection roller 3 has an irregular shape, or if it shakes or becomes eccentric during rotation, the scanning housing 55 will use the bottom light lens 56 to determine the eccentricity of the detection roller 3, thereby detecting the defective detection roller 3.

[0031] When the scanning housing 55 performs a vertical scanning operation from top to bottom through the light lens 56, the push slide 53 of each detection device 5 also controls the corresponding bending link 54 to extend and retract. That is, the push slide 53 away from the rotating module 4 pushes the bending link 54 downward, and the push slide 53 close to the rotating module 4 retracts the bending link 54 upward. This causes the scanning housing 55 to shift obliquely towards the side closer to the detection roller 3, thereby causing the light lens 56 of the vertically fixed chassis 21 to deflect towards the side of the detection roller 3 to perform the scanning operation. Then, based on whether the end of the detection roller 3 shakes or moves eccentrically, it is determined whether there is an eccentric protrusion at the end of the detection roller 3.

[0032] After each comprehensive inspection of the detection roller 3, during the return process to the collection base 14, the pusher slide 53 will pull the bending connecting rod 54 back to the initial horizontal position. Through the transverse 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 work can be carried out to ensure that the detection equipment 5 can be perfectly reset.

[0033] Example 2, please refer to Figures 1-8 This invention provides a technical solution: Based on embodiment 1, the rotating module 4 includes a diversion base 41. A rotary motor 42 is fixedly connected to the axis of the inner cavity of the diversion 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. An outer rotating cylinder 45 is fixedly connected to the bottom of the plug-in top cover 44 via a plug. The inner cavity of the outer rotating cylinder 45 is uniformly provided with through-cut grooves. Inner sliding push plates 46 are uniformly arranged on the inner wall of the outer rotating cylinder 45 through the through-cut grooves. Compression spring bands 47 are symmetrically arranged 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 plate 46 is fixedly connected to the inner wall of the outer rotating cylinder 45. The diversion inner plate 23 can pressurize the inside of the diversion base 41 and pressurize the inside 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 cylinder 45 is rotatably connected to the upper surface of the rotary motor 42, the outer surface of the diversion base 41 is fixedly connected to the axis of the inner cavity of the fixed base 21, the outer surface of the connecting shaft 43 is slidably connected to the inner wall of the inner sliding push plate 46 through the guide groove, and the outer surface of the inner sliding push plate 46 extends to the outside of the outer rotating cylinder 45.

[0034] The sliding device 22 includes a filling disc 221. The inner cavity of the filling disc 221 is evenly provided with inlay grooves, and ball rotors 222 are evenly arranged within these grooves. Segmented tie rods 223 are evenly arranged on the outer side of the filling disc 221 through through-holes. A control crane 224 is fixedly connected to the top of each segmented tie rod 223, and anchor rods 225 are fixedly connected to the upper surface of the control crane 224. The outer surface of the ball rotors 222 is in rolling contact with the inner cavity of the filling disc 221 through the inlay grooves, and the outer surface of the ball rotors 222 extends to the outside of the filling disc 221. The bottom end of each segmented tie rod 223 is 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 base 21, the side of the filling disc 221 is slidably connected to the axis of the inner cavity of the fixed base 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 fitted onto the bottom of the outer surface of the outer rotating cylinder 45, the inner guide plate 23 will pressurize the inside of the outer rotating cylinder 45 through the guide base 41, causing each inner sliding push plate 46 to push outward of the outer rotating cylinder 45. In turn, the protruding inner sliding push plate 46 will press against the inner wall of the detection roller 3, thereby achieving the effect of squeezing the inner wall of the detection roller 3 and fixing the detection roller 3. The rotary 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 fitted onto the outer surface of the outer rotating cylinder 45, its bottom will rotate relative to the ball rotor 222, thereby effectively reducing the wear problem at the bottom of the detection roller 3. At the same time, by controlling the crane 224 to pull the segmented tie rod 223, the filling disc 221 can be lifted vertically. At this time, the squeezing and fixing effect of the inner sliding push plate 46 on the detection roller 3 is weakened, which causes the filling disc 221 to drive the detection roller 3 to rise. After reaching a certain height, the detection roller 3 is tightened and rotated, thereby measuring the rotation status of the detection roller 3 at different heights and minimizing the systematic errors generated by the device.

[0037] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort 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, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
