Description

Technical Field

[0001] The invention relates to the technical field of tire thermal expansion coefficient detection devices, and in particular to a motorcycle tire expansion detection device based on laser scanning. Background Art

[0002] A motorcycle wheel consists of a hub, hub axle, and tire. The tire is filled with air pressure and expands when heated. The thermal expansion is mainly caused by the following factors: 1. Frictional heat: The friction between the tire and the ground generates heat, which is more obvious when driving at high speeds or braking suddenly. 2. Ambient temperature: Hot weather or high road temperature will aggravate the rise in tire temperature. 3. Tire material: Materials such as rubber will expand at high temperatures, causing the tire volume to increase. 4. Internal air pressure: The increase in temperature will increase the internal air pressure of the tire, further aggravating the expansion.

[0003] Thermal expansion of motorcycle tires not only changes their shape, affecting grip and handling stability, but also increases the probability of blowouts due to overexpansion. Furthermore, uneven tire expansion accelerates tire wear and shortens tire life. Therefore, thermal expansion testing of motorcycle tires after they leave the factory is essential. However, existing testing methods, such as tire pressure testing, often focus on indirect measures, such as monitoring air pressure. Currently, a lack of dedicated testing devices prevents direct reflection of changes in the tire's thermal expansion coefficient caused by temperature fluctuations. Summary of the Invention

[0004] The purpose of the present invention is to provide a motorcycle tire expansion detection device based on laser scanning. By screwing a rotating bucket inside the main shell assembly, the wheel hub and tire to be tested can be introduced. At the same time, the rotating action of the rotating bucket itself, in conjunction with the use of the rotating drive module, the pressure roller assembly and the thermal cycle assembly, uses a laser scanning probe to form the thermal expansion coefficient detection in different temperature environments when the tire is rotating.

[0005] The objective of the present invention is achieved through such a technical solution: a motorcycle tire expansion detection device based on laser scanning, comprising a main housing assembly, a rotating bucket assembly, a rotary drive module, a pressure roller assembly, and a thermal circulation assembly. The main housing assembly includes a laser scanning probe, the rotating bucket assembly includes a rotating bucket, a servo electric cylinder, and an active roller, the rotary drive module includes an active large gear, the pressure roller assembly includes a passive safety roller, and the thermal circulation assembly includes an external circulation coil and an air suction circulation fan.

[0006] One side of the main shell assembly is connected to the material inlet channel. The laser scanning probe is symmetrically installed on one side of the top of the main shell assembly. The main body of the servo electric cylinder is screwed to the other side of the main shell assembly. The outer side of one end of the rotating bucket is screwed to the lower end of the material inlet channel. The telescopic rod of the servo electric cylinder is screwed to the lower part of the other end of the rotating bucket. The active roller is screwed to the upper part of the other end of the rotating bucket. The bottom end of the rotating bucket is screwed to the bottom roller.

[0007] The driving large gear is plugged and fixed to the outer end of the rotating shaft of the active roller. A rotatable driving gear is installed on the top side of the main body of the servo electric cylinder. A follower frame is also fixed on one side of the main body of the servo electric cylinder. The passive safety roller is arranged and screwed on the head end of the follower frame. When the rotation of the rotating bucket drives the wheel hub to be tested and the tire to be introduced into the position where they are in rolling contact with the bottom rotating roller and the active roller, as the rotating bucket continues to rotate, it can drive the driving gear to engage with the driving large gear, and the passive safety roller is moved to a position where it keeps a certain distance from the outside of the tire.

[0008] One end inlet of the external circulation winding pipe is connected to the lower end of one side of the main body of the main shell assembly, and the other end outlet is connected to the upper end of the other side of the main body of the main shell assembly. An electric heating mechanism is installed in the main body of the external circulation winding pipe, and the suction circulation fan is coaxially fixed to one end of the driving gear.

[0009] The use process of the technical solution of the present invention is as follows:

[0010] When the bucket is tilted toward the inlet channel, the inlet of the bucket extends beyond the inlet channel, making it easier to place the wheel hub and tire into the inner channel of the bucket.

[0011] After the wheel and tire are placed into the entrance of the rotating bucket, the servo electric cylinder is started, and the telescopic rod of the servo electric cylinder is extended. The head of the telescopic rod of the servo electric cylinder is connected with the lower part of the other end of the rotating bucket to drive the rotating bucket to rotate toward the inside of the main shell assembly, driving the wheel and tire to roll toward the active roller.

[0012] After the tire is in contact with the active roller and the bottom roller on the outside, it continues to rotate toward the inside of the main housing assembly through the rotating bucket, so that the active large gear and the drive gear can form a coordinated transmission;

[0013] And synchronously, when the bucket rotates to the position where the active large gear is engaged with the drive gear, the passive safety roller is also moved to a certain position outside the tire;

[0014] The active roller is driven to rotate actively by the cooperation of the automatically rotating driving gear and the active large gear. The friction between the active roller and the outer surface of the tire drives the wheel hub and the tire to roll and rotate between the active roller, the bottom roller and the passive safety roller.

[0015] By starting the electric heating mechanism connected to the outer circulation coil, heat can be generated in the inner pipe of the outer circulation coil, and while the driving gear and the active large gear form a coordinated transmission, the air suction circulation fan is just opposite to the inlet of the outer circulation coil;

[0016] When the driving gear drives the tire to roll and rotate through the transmission formed by the cooperation with the active large gear, the rotation of the suction circulation fan can also form air circulation power inside the external circulation coil, so that the heated air in the external circulation coil is circulated and blown into the main body of the main shell assembly, maintaining a certain temperature environment inside the main body of the main shell assembly;

[0017] Changes in temperature environment will cause changes in tire pressure, causing the tire to expand thermally. By using the automatic scanning of the laser scanning probe, we can not only obtain the shape outline of the tire before the temperature rises, but also scan the tire shape outline after the temperature rises to a certain value, thereby testing the thermal expansion coefficient of different tires to adapt to temperature changes.

[0018] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0019] (1) The present invention rotates the swivel bucket at the inner lower end of the inlet channel connected to the main body of the main housing assembly, and combines the channel formed inside the swivel bucket itself. As the servo electric cylinder drives the swivel bucket to form different rotation states, the internal channel of the swivel bucket can form different inclination angles, thereby facilitating the placement of the wheel hub to be inspected into the internal channel of the swivel bucket when the swivel bucket is tilted toward one side of the inlet channel. In addition, when the swivel bucket rotates toward the inside of the main housing assembly, under the action of gravity, the tire can roll from the inlet end of the swivel bucket to the position to be inspected in contact with the active roller. The structure is simple and the operation is convenient.

[0020] (2) After the bucket rotates to the outside of the tire and contacts the active roller, as the bucket continues to rotate toward the inside of the main housing assembly, not only can the active large gear at the outer end of the active roller shaft be matched with the automatically rotating drive gear, but the passive safety roller can also be moved to a position maintaining a certain distance from the outside of the tire, thereby driving the tire to roll and rotate within a certain range of sway, and also conveniently adapting to changes in tire thermal expansion caused by temperature increases;

[0021] (3) In addition, the present invention can drive the rotation of the suction circulation fan while the driving gear rotates automatically. The rotation of the suction circulation fan cooperates with the internal electric heating mechanism of the external circulation winding tube to form a cyclic heating to increase the temperature of the internal space of the main shell component, which is energy-saving and environmentally friendly.

DETAILED DESCRIPTION

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] like Figures 1-13The laser scanning-based motorcycle tire expansion detection device shown in FIG. 1 has a main body of a main housing assembly 1 connected to an inlet passage 102, a laser scanning probe 104 symmetrically mounted on one side of the top inner portion of the main housing assembly 1, a main body of a servo electric cylinder 207 screwed to the other side of the inner portion of the main housing assembly 1, a channel for facilitating tire rolling is provided inside a rotating bucket 203, an outer side of one end of the rotating bucket 203 is screwed to the lower inner portion of the inlet passage 102, a telescopic rod of the servo electric cylinder 207 is screwed to the lower portion of the other end of the rotating bucket 203, a driving roller 209 is screwed to the upper portion of the other end of the rotating bucket 203, and a bottom rotating roller 213 is arranged and screwed to the inner bottom end of the rotating bucket 203, which can form different rotation angles of the rotating bucket 203, so that the wheel hub and tire to be detected are guided into a position where they are in rolling contact with both the bottom rotating roller 213 and the driving roller 209.

[0046] The driving large gear 301 is plugged and fixed to the outer end of the rotating shaft of the active roller 209. A rotatable driving gear 303 is installed on one side of the top end of the main body of the servo electric cylinder 207. A follower frame 401 is also fixed to one side of the main body of the servo electric cylinder 207. The passive safety roller 402 is arranged and screwed to the head end of the follower frame 401. When the rotation of the rotating bucket 203 drives the wheel hub to be inspected and the tire to be introduced into the position where they are in rolling contact with the bottom rotating roller 213 and the active roller 209, as the rotating bucket 203 continues to rotate, it can drive the driving gear 303 to engage with the driving large gear 301, and the passive safety roller 402 is moved to a position where it is kept a certain distance from the outside of the tire.

[0047] Furthermore, the active roller 209, the bottom roller 213, and the passive safety roller 402 that are in rolling contact with the outside of the tire can cover more than half of the tire, so that the tire can roll freely between the active roller 209, the bottom roller 213, and the passive safety roller 402 without falling out;

[0048] The purpose of keeping the passive safety roller 402 at a certain distance from the outside of the tire is to enable the tire to roll and rotate within a reasonable range of sway and to adapt to the thermal expansion changes of the tire during subsequent testing;

[0049] The active roller 209, the bottom rotating roller 213 and the passive safety roller 402 are all curved structures that fit the outer surface of the tire.

[0050] Furthermore, since the active roller 209, the bottom rotating roller 213 and the passive safety roller 402 form a fixed profile, the device is only applicable to the detection of tires of a certain size.

[0051] One end inlet of the outer circulation winding pipe 501 is connected to the lower end of one side of the main body of the main housing assembly 1, and the other end outlet is connected to the upper end of the other side of the main body of the main housing assembly 1. An electric heating mechanism is installed in the main body of the outer circulation winding pipe 501. The suction circulation fan 505 is coaxially fixed to one end of the driving gear 303. When the driving gear 303 is engaged with the driving large gear 301, the suction circulation fan 505 is exactly opposite to the inlet of the outer circulation winding pipe 501.

[0052] Here's how it works:

[0053] The interior of the main body of the main housing assembly 1 is used to provide space for testing tires in a certain temperature environment;

[0054] The wheel hub and tire to be inspected can enter the main body of the main housing assembly 1 through the entry channel 102;

[0055] Before the test, the tire is inflated according to the test conditions, and the tire has a set air pressure;

[0056] When the hopper 203 is tilted toward the inlet passage 102, the entrance of the hopper 203 extends beyond the inlet passage 102, making it easier to place the wheel hub and tire into the inner passage of the hopper 203.

[0057] After the wheel hub and tire are placed into the entrance of the rotating bucket 203, the servo electric cylinder 207 is activated, and the telescopic rod of the servo electric cylinder 207 is extended. The head of the telescopic rod of the servo electric cylinder 207 is screwed with the lower part of the other end of the rotating bucket 203, which can drive the rotating bucket 203 to rotate toward the inside of the main housing assembly 1, driving the wheel hub and tire to roll toward the active roller 209;

[0058] After the tire contacts the active roller 209 and the bottom roller 213 on the outside of the tire, the tire continues to rotate toward the inside of the main body of the main housing assembly 1 through the rotating bucket 203, so that the active large gear 301 and the driving gear 303 form a coordinated transmission;

[0059] And synchronously, when the rotating bucket 203 rotates to the position where the active large gear 301 is engaged with the driving gear 303, the passive safety roller 402 is also moved to a position a certain distance from the outside of the tire;

[0060] At this time, the outer side of the tire is rolled and clamped between the active roller 209, the bottom roller 213, and the passive safety roller 402;

[0061] The automatic rotating drive gear 303 and the active large gear 301 form a cooperative transmission, which can drive the active roller 209 to actively rotate. The frictional contact between the active roller 209 and the outer surface of the tire can drive the wheel hub and the tire to roll and rotate between the active roller 209, the bottom rotating roller 213 and the passive safety roller 402.

[0062] Furthermore, since the passive safety roller 402 actually maintains a certain distance from the outside of the tire, the tire can be rolled and rotated within a reasonable range of sway.

[0063] The purpose of performing the thermal expansion test after the tire is to better simulate the changes in the tire's internal air pressure caused by external temperature changes in an actual driving environment. Another purpose is to facilitate the laser scanning probe 104 fixed to the top of the main body of the main housing assembly 1 to perform a comprehensive scan and detection of the tire changes while the tire is rolling and rotating.

[0064] By activating the electric heating mechanism connected to the outer circulation coil 501, heat can be generated in the inner pipe of the outer circulation coil 501. At the same time as the driving gear 303 and the active large gear 301 form a transmission, the suction circulation fan 505 is exactly opposite to the inlet of the outer circulation coil 501.

[0065] When the driving gear 303 drives the tire to roll and rotate through the transmission formed by the cooperation with the active large gear 301, the rotation of the suction circulation fan 505 can also generate air circulation power inside the external circulation coil 501, so that the heated air in the external circulation coil 501 is circulated and blown into the main body of the main housing assembly 1, thereby maintaining a certain temperature environment inside the main body of the main housing assembly 1;

[0066] Changes in temperature can cause changes in tire pressure, causing thermal expansion of the tire. Automatic scanning using the laser scanning probe 104 can not only determine the tire's shape before the temperature rises, but also scan the tire's shape after the temperature rises to a certain value, thereby enabling testing of the thermal expansion coefficients of different tires to adapt to temperature changes.

[0067] The thermal expansion coefficient of a tire is the regularity coefficient of how its geometric characteristics change with temperature under the effect of thermal expansion and contraction. It is the ratio of the change in its geometric dimensions when the temperature changes by 1 degree Celsius to its dimensions at a certain temperature.

[0068] Assume that at a certain temperature, the volume of the tire scanned by the laser scanning probe 104 is V1. After the temperature changes by 1 degree Celsius, the cross-sectional area of ​​the tire scanned by the laser scanning probe 104 is V2. (V2-V1) / V1 is the thermal expansion coefficient of the tire at this time.

[0069] After the test is completed, the servo electric cylinder 207 is started again to lift the rotating bucket 203 to a position tilted toward the side of the inlet passage 102 , so that the wheel hub and the tire can roll out of the inlet passage 102 under the action of gravity.

[0070] The specific structure of the main shell assembly 1 and the rotating bucket assembly 2 is as follows Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the inlet channel 102 is connected to one side of the cavity wall of the outer shell 101, and the laser scanning probe 104 is symmetrically installed and fixed on the top of the inner cavity on one side of the outer shell 101;

[0071] A temperature sensor 105 is also mounted on the upper end of one side of the inner cavity of the outer shell 101 to monitor the temperature changes of the inner space of the outer shell 101 in real time.

[0072] A control center 103 is fixedly mounted on the outer main surface of the outer shell 101, which can automatically control the electronic control components in the device;

[0073] The side cover 201 is fixedly connected to the other side of the cavity wall of the outer shell 101, and the electric cylinder base 205 is fixedly installed on the inner side of the side cover 201. The main body of the servo electric cylinder 207 is rotatably connected to the electric cylinder base 205. The side cover 201 can be detached from the outer shell 101, which facilitates the installation of the servo electric cylinder 207.

[0074] The lower ends of both sides of the inlet channel 102 are fixedly mounted with a bucket swivel seat 202. A bucket shaft 204 is symmetrically fixed to the outer side of one end of the bucket 203. The bucket shaft 204 on the same side is rotatably connected to the bucket swivel seat 202.

[0075] An electric cylinder rotary seat 206 is fixed to the lower part of the other end of the rotary bucket 203, and the telescopic rod head of the servo electric cylinder 207 is rotatably connected to the electric cylinder rotary seat 206;

[0076] There are ventilation grilles on both sides of the main body of the swivel bucket 203 to facilitate air circulation.

[0077] The active roller seat 208 is fixedly connected to the upper portion of the other end of the rotating bucket 203, and the rotating shaft of the active roller 209 is rotatably connected to the active roller seat 208;

[0078] The top of the rotating bucket 203 is also fixedly connected to a slow-moving rack 210 on both sides, and a slow-moving gear 211 is fixed to both ends of the wheel hub shaft. Both sides of the slow-moving rack 210 are provided with inclined surfaces, so that as the rotating bucket 203 tilts toward the inner cavity of the outer shell 101, when the wheel hub and the tire roll from the channel inside the rotating bucket 203 toward the active roller 209, the slow-moving gear 211 can roll from the inclined surface on one side of the slow-moving rack 210 to a position where it cooperates with the teeth of the slow-moving rack 210. That is, after the tire rolls to the position where the slow-moving gear 211 cooperates with the slow-moving rack 210, it can be guided by the cooperation formed by the slow-moving rack 210 and the slow-moving gear 211 and slowly move from the entrance of the rotating bucket 203 to the active roller 209, thereby eliminating the problem of excessive falling potential energy caused by the tire rolling freely in the internal channel of the rotating bucket 203 and rebounding after contacting the active roller 209;

[0079] Before the outer surface of the tire contacts the active roller 209, the slow-moving gear 211 has been disengaged from the slow-moving rack 210, so that the cooperation between the slow-moving gear 211 and the slow-moving rack 210 will not interfere with the rotation of the tire in the detection state;

[0080] After the detection is completed, as the rotating bucket 203 tilts toward the side of the inlet channel 102, and the slow-moving gear 211 cooperates with the teeth of the slow-moving rack 210 through the inclined surface on the other side of the slow-moving rack 210, the tire can be slowly withdrawn from the rotating bucket 203;

[0081] The tilt angle of the rotating bucket 203 itself is sufficient to support the slow-moving gear 211 and the slow-moving rack 210 to form a coordinated transmission under the action of gravity;

[0082] The bottom entrance of the rotating bucket 203 is connected to an inclined guide surface 214. A straight guide surface 215 is connected between the bottom end of the rotating bucket 203 and the inclined guide surface 214. The bottom roller seat 212 is fixedly connected to the straight guide surface 215. The bottom rotating rollers 213 are arranged and rotated in the bottom roller seat 212.

[0083] The angle between the inclined guide surface 214 and the straight guide surface 215 is an obtuse angle. By providing the inclined guide surface 214 at the entrance of the hopper 203, the purpose is to facilitate the placement of the tire to be tested after the hopper 203 is tilted toward the side of the inlet channel 102, so that the tire will not fall back due to its own gravity after being placed in the space between the top surface of the inclined guide surface 214 and the hopper 203.

[0084] The specific structure of the rotary drive module 3 and the pressure roller assembly 4 is as follows Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the drive motor 302 is mounted and fixed on one side of the top end of the servo electric cylinder 207, and the drive gear 303 is inserted and fixed in the rotating shaft of the drive motor 302. The purpose of fixing the drive motor 302 to the servo electric cylinder 207 instead of fixing it to the inner cavity side wall of the outer shell 101 is that after the drive motor 302 and the servo electric cylinder 207 are fixed, the movement of the drive gear 303 and the active large gear 301 can be regarded as moving with the same component as the reference, thereby reducing the problem of accuracy degradation caused by the increase of the relative reference.

[0085] The side connecting frame 403 is fixedly connected to the head end side of the follower frame 401, and the speed sensor 404 is installed and fixed in the side connecting frame 403. The position of the speed sensor 404 is opposite to the position of the wheel hub. In conjunction with the feedback element pre-fixed in the wheel hub, the tire speed can be monitored in real time to automatically control the speed provided by the drive motor 302.

[0086] The specific structure of the thermal cycle component 5 is as follows Figure 10 and Figure 11 As shown, the inlet end of the outer circulation winding pipe 501 is connected to the lower end of one side wall of the outer shell 101, and the outlet end is connected to the upper end of the other side wall of the outer shell 101, so that the inlet end and the outlet end of the outer circulation winding pipe 501 are not directly opposite each other in the inner cavity of the outer shell 101, thereby improving the efficiency of the heated air circulation in the inner cavity of the outer shell 101;

[0087] An inner bracket 502 is also fixedly mounted on the inner cavity side wall of the outer shell 101. The outer surface of the inlet end of the outer circulation pipe 501 is fixedly engaged with the inner bracket 502, which can improve the safety of the connection between the outer circulation pipe 501 and the outer shell 101.

[0088] A heating pipe 503 is connected to the main pipe of the external circulation bypass pipe 501 , and a heating wire 504 is installed inside the heating pipe 503 to heat the air flowing through it.

[0089] Preferably, if Figure 12 and Figure 13As shown, a safety rotary door assembly 6 is also installed at the position where the inlet channel 102 meets the outside of the outer shell 101, which is used to realize the opening and closing processing of the inlet channel 102. The opening and closing rotary seat 601 is located just above the inlet channel 102 and is fixedly installed in the side wall of the outer shell 101. The inner top of each set of opening and closing fans 602 is fixedly connected with an opening and closing shaft 603, and the opening and closing shaft 603 is rotatably connected to the opening and closing rotary seat 601. The inner end of one set of opening and closing shafts 603 is plugged and fixed with an opening and closing gear 604 and an opening and closing bevel gear 605. The adapter bevel gear 608 is engaged with one side of the opening and closing bevel gear 605. The outer top surface of 02 is fixed with an adapter seat 606, and an adapter shaft 607 is rotatably connected in the adapter seat 606. The adapter bevel gear 608 is plugged and fixed to one end of the adapter shaft 607, and the other end of the adapter shaft 607 is plugged and fixed with a transfer toothed pulley 609. The outer end of one set of the bucket shaft 204 is plugged and fixed with a rotating toothed pulley 610, and the toothed belt 611 is sleeved and installed between the transfer toothed pulley 609 and the rotating toothed pulley 610; as the bucket 203 tilts with the bucket shaft 204 as the reference, the opening and closing fan 602 can synchronously form an opening and closing action, that is, when the bucket 203 and the bucket shaft 204 are moved into the bucket, the opening and closing fan 602 can be opened and closed synchronously. When one side of the material channel 102 rotates, a coordinated transmission can be formed between the rotating toothed pulley 610 and the transfer toothed pulley 609 through the toothed belt 611, so that the transfer bevel gear 608 keeps rotating in the same direction as the bucket shaft 204, and the opening and closing bevel gear 605 and the transfer bevel gear 608 form a coordinated transmission, which can drive the two sets of mutually meshed opening and closing gears 604 to form synchronous rotation, driving the opening and closing fan 602 to form an opening action, conversely, when the bucket 203 rotates toward the inner cavity side of the outer shell 101, the opening and closing fan 602 forms a closing action; and the rotation action of the bucket 203 and the opening and closing action of the opening and closing fan 602 will not form Mutual interference, that is, before the rotatable bucket 203 rotates to the entrance of the inlet channel 102, the opening and closing fan 602 is opened to a position where it does not interfere with the rotatable bucket 203 extending out of the inlet channel 102, and before the opening and closing fan 602 is closed to the position covering the inlet channel 102, the entrance of the rotatable bucket 203 has been rotated back into the inlet channel 102, so that the opening and closing fan 602 can form a covering effect on the inlet channel 102 as the rotatable bucket 203 rotates, so as to achieve the purpose of sealing the internal space of the outer shell 101 during the detection process, so that the heat inside the outer shell 101 will not leak out too much, thereby achieving energy saving.
