Description

Technical Field

[0001] The invention relates to the technical field of chemical fiber industry, and in particular to a laser roller cleaning automatic centering device. Background Art

[0002] When using spinning roller laser cleaning equipment, due to the high position of the roller and the small space in the workshop, when personnel use equipment such as a crane to carry the laser cleaning equipment to the vicinity of the roller, the operator needs to manually install the equipment on the roller, and it must be ensured that the center of the laser cleaning equipment and the center of the roller are aligned during installation. Since the clamping claws of the laser cleaning device are short (if the clamping is too long, the laser cannot clean the clamping position), the laser cleaning device itself is heavy, and the long-distance cantilever clamping of the claws alone may not be able to align the center of the laser cleaning equipment with the center of the roller, which may cause eccentric clamping. When the laser generator on the laser cleaning equipment moves along the center direction of the roller to perform laser cleaning on the roller surface, the eccentric clamping will cause the focal length of the laser generator and the roller surface to be out of the set range in a certain section of the stroke, thereby causing the laser cleaning to fail or the cleaning effect to be unsatisfactory. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide a laser roller cleaning automatic centering device for laser cleaning positioning.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A laser roller cleaning automatic centering device, characterized by comprising:

[0006] The first center face alignment mechanism is used for preliminary positioning of the laser cleaning equipment;

[0007] The second center surface alignment mechanism is used for automatically centering the laser cleaning equipment.

[0008] In the present invention, the first centering surface of the laser cleaning equipment bears part of the weight of the laser cleaning equipment through the first centering surface alignment mechanism, and performs preliminary positioning. However, since the other part of the weight of the laser cleaning equipment is borne by the operator, there will be a certain inclination or angle deviation between the center of the laser cleaning equipment and the center of the roller. The second centering surface automatically centers the laser cleaning equipment through the second centering surface alignment mechanism.

[0009] Preferably, the first center surface alignment mechanism comprises:

[0010] A first positioning ring;

[0011] A first nylon introduction ring is arranged on the upper part of the first positioning ring and is located outside the first positioning ring;

[0012] A second nylon introduction ring is arranged at the lower part of the first positioning ring and is located outside the first positioning ring;

[0013] Two positioning universal balls are arranged on the first positioning ring and are located inside the first positioning ring.

[0014] When the laser cleaning equipment is transported to the vicinity of the roller by means of external force equipment such as a crane, the operator places the second nylon guide ring of the laser roller cleaning automatic centering device of the present invention on the laser cleaning equipment close to the circular surface of the roller, and then drops the first nylon guide ring to rest on the cylindrical surface of the roller. At this time, the external force equipment such as the crane is released, and the laser cleaning is subsequently clamped on the cylindrical surface of the roller entirely by the operator's manpower. The operator pushes the laser cleaning equipment into the roller, so that the first nylon guide ring supports the laser cleaning equipment to slide on the cylindrical surface of the roller. When the fixed steel positioning universal ball on the laser cleaning equipment contacts the cylindrical surface of the roller, the positioning universal ball supports the laser cleaning equipment to slide on the cylindrical surface of the roller, and the sliding friction is changed to rolling friction.

[0015] Preferably, the diameter of the first nylon introduction ring is smaller than the diameter of the second nylon ring, the diameter of the roller is smaller than the diameter of the first nylon introduction ring, and the diameter of the circle aligned with the two positioning universal balls is the same as the diameter of the roller.

[0016] Preferably, two positioning universal balls are located on the upper part of the first positioning ring.

[0017] Two positioning universal balls distributed along the circumference are located above the roller. The first nylon guide ring is on the outside of the steel universal ball. The circle that the positioning universal ball contacts and aligns with is the same diameter as the roller circle, and the roller circle diameter is smaller than the first nylon guide ring circle diameter. The first nylon guide ring circle diameter is smaller than the second nylon ring circle diameter. The laser cleaning equipment first approaches through the second nylon guide ring, uses the first nylon ring and the roller circular surface for initial positioning, and then the positioning universal ball and the roller cylindrical surface are positioned more accurately. Among them, the first nylon ring also plays a role in protecting the roller surface, preventing the edges and corners on the positioning universal ball from scratching the roller surface.

[0018] Preferably, the first center surface alignment mechanism further comprises a first laser sensor arranged on the first positioning ring; and the positioning universal ball can rotate 360 ​​degrees.

[0019] The ball on the positioning universal ball part of the present invention can rotate 360 ​​degrees, has low use cost, is easy to replace, and has low friction, so that the laser cleaning equipment changes from sliding friction to rolling friction on the cylindrical surface of the roller.

[0020] Preferably, the second center surface alignment mechanism comprises:

[0021] A second positioning ring;

[0022] Two third nylon introduction rings are respectively arranged on the upper part of the second positioning ring and the lower part of the second positioning ring, and are both located outside the second positioning ring;

[0023] Two movable universal balls are respectively arranged on the upper part of the first positioning ring and the lower part of the second positioning ring, and are both located on the inner side of the second positioning ring.

[0024] When the laser cleaning equipment slides on the cylindrical surface of the roller to the second center surface alignment mechanism, the second center surface alignment mechanism is provided with two third nylon guide rings at the top and bottom, a steel movable universal ball and a second laser sensor. The laser cleaning equipment contacts the third nylon guide ring, and the circle diameter of the third nylon guide ring centering adjustment is larger than the circle diameter of the fixed steel universal ball contact roller centering adjustment, which facilitates the roller to enter the second centering surface. The circle diameter of the third nylon guide ring centering adjustment is smaller than the movable universal ball assembly, so that the third nylon guide ring protects the surface of the roller and the movable universal ball assembly, preventing the movable universal ball assembly from scratching the roller surface.

[0025] Preferably, the diameter of the circle formed by the two third nylon introduce rings is larger than the diameter of the circle aligned with the two positioning universal balls; the diameter of the circle when the two movable universal balls are not in contact with the roller is smaller than the diameter of the circle aligned with the two positioning universal balls, and when the roller is introduced through the third nylon introduce ring and contacts the spherical surface of the movable universal balls, the roller squeezes the two movable universal balls, and the movable universal balls are compressed to form a reverse force, so that the laser cleaning equipment automatically aligns with the roller.

[0026] Through the fixed universal ball on the first centering surface and the movable universal ball on the second centering surface, the laser cleaning equipment is automatically centered and its center is aligned with the center of the roller.

[0027] Preferably, the movable universal ball comprises a fixed block, a spherical body, and a compression spring abutting between the spherical body and the fixed block.

[0028] Preferably, the fixing block is provided with a waist-shaped hole for adjusting the installation position. The universal ball fixing block is provided with a waist-shaped hole, which can adjust the position of the movable universal ball assembly to obtain the appropriate spring compression force of the assembly to act on the roller surface.

[0029] The universal ball fixing block can be matched with the threaded steel universal ball body and can slide in the round hole on the ball fixing block. The outer diameter of the large washer is larger than the diameter of the round hole on the universal ball fixing block. The large washer is installed on the threaded steel universal ball and tightened into one piece through the thread. One side of the compression spring is installed on the large washer and the other side is installed on the cover plate. The cover plate is fixed to the universal ball fixing block by screws, so that the threaded steel universal ball can only move in the cavity of the universal ball fixing block. The reaction force of the compressed compression spring acts on the large washer and the cover plate, so that the threaded steel universal ball is always ejected and pressed against the circular surface of the inner cavity of the universal ball fixing block.

[0030] The fixed universal ball assemblies are arranged on both sides above when the laser cleaning equipment clamps the roller, and the movable universal ball assemblies are arranged on both sides above and below when the laser cleaning equipment clamps the roller, to ensure the reliability of automatic centering of the equipment.

[0031] Preferably, when the circular diameter of the two movable universal ball contact rollers adjusted by centering is equal to the circular diameter of the two positioning universal ball contact rollers adjusted by centering, the compression amount of the spring is half of the difference between the circular diameter of the two positioning universal ball contact rollers adjusted by centering and the circular diameter of the two movable universal ball contact rollers adjusted by centering.

[0032] In the present invention, the first centering surface and the second centering surface are provided with a first laser sensor and a second laser sensor, which respectively measure the distance between the laser cleaning device and the roller circle. When the deviation between the two does not meet the requirements, the laser cleaning equipment needs to be re-clamped to ensure the accuracy of automatic centering of the laser cleaning device.

[0033] The present invention also provides a laser roller cleaning device, comprising a machine body, on which the laser roller cleaning automatic centering device as described above is provided.

[0034] The beneficial effects of the present invention compared with the prior art are:

[0035] (1) The present invention aligns the center of the device with the center of the roller through the first centering surface and the second centering surface, automatically centers the device, and ensures that the distance between the laser cleaning device and the roller surface is within a set range.

[0036] (2) In the present invention, laser sensors are provided on both the first centering surface and the second centering surface to provide feedback on whether the device is clamped accurately.

[0037] (3) In the present invention, the first centering surface is provided with the first nylon guide ring and the second nylon ring on the upper and lower sides, and the fixed universal ball assemblies are distributed on the left and right sides. The second nylon guide ring is close to the roller surface, and the first nylon guide ring is introduced into the roller surface to bear the gravity of the equipment placement, reduce the force of the operator lifting the equipment, and the fixed universal ball assembly performs the preliminary positioning of the front end of the equipment. The second centering surface is provided with the third nylon guide ring and the movable universal ball assembly on the upper and lower sides. The movable universal ball assembly is provided with a compression spring. The spring compression reaction force acts on the circular surface of the roller to automatically center the equipment. The third nylon guide ring protects the roller surface from being scratched by the movable universal ball assembly, and the force of the movable universal ball assembly on the upper and lower sides automatically centers the middle end of the equipment.

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] like Figure 1 to Figure 7 As shown, this embodiment is a laser roller cleaning automatic centering device, comprising:

[0051] The first center face alignment mechanism is used for preliminary positioning of the laser cleaning equipment;

[0052] The second center surface alignment mechanism is used for automatically centering the laser cleaning equipment.

[0053] In this embodiment, the first centering surface of the laser cleaning equipment bears part of the weight of the laser cleaning equipment through the first centering surface alignment mechanism, and performs preliminary positioning. However, since the other part of the weight of the laser cleaning equipment is borne by the operator, there will be a certain inclination or angle deviation between the center of the laser cleaning equipment and the center of the roller. The second centering surface automatically centers the laser cleaning equipment through the second centering surface alignment mechanism.

[0054] In one embodiment, the first center surface alignment mechanism comprises:

[0055] A first positioning ring;

[0056] A first nylon introduction ring 2 is arranged on the upper part of the first positioning ring and is located outside the first positioning ring;

[0057] A second nylon introduction ring 4 is arranged at the lower part of the first positioning ring and located outside the first positioning ring;

[0058] Two positioning universal balls (respectively a first positioning universal ball 1 and a second positioning universal ball 3 ) are arranged on the first positioning ring and located on the inner side of the first positioning ring.

[0059] When the laser cleaning equipment is moved to the vicinity of the roller by means of external force equipment such as a crane, the operator places the second nylon guide ring of the laser roller automatic centering device of this embodiment on the laser cleaning equipment close to the circular surface of the roller, and then drops the first nylon guide ring to rest on the cylindrical surface of the roller. At this time, the external force equipment such as the crane is released, and the laser cleaning is subsequently clamped on the cylindrical surface of the roller entirely by the operator's manpower. The operator pushes the laser cleaning equipment into the roller, so that the first nylon guide ring supports the laser cleaning equipment to slide on the cylindrical surface of the roller. When the fixed steel positioning universal ball on the laser cleaning equipment contacts the cylindrical surface of the roller, the positioning universal ball supports the laser cleaning equipment to slide on the cylindrical surface of the roller, and the sliding friction is changed to rolling friction.

[0060] In one embodiment, the diameter of the first nylon introduction ring is smaller than the diameter of the second nylon ring, the diameter of the roller is smaller than the diameter of the first nylon introduction ring, and the diameter of the circle aligned with the two positioning universal balls is the same as the diameter of the roller.

[0061] In one embodiment, two positioning universal balls are located on the upper part of the first positioning ring.

[0062] Two positioning universal balls distributed along the circumference are located above the roller. The first nylon guide ring is on the outside of the steel universal ball. The circle that the positioning universal ball contacts and aligns with is the same diameter as the roller circle, and the roller circle diameter is smaller than the first nylon guide ring circle diameter. The first nylon guide ring circle diameter is smaller than the second nylon ring circle diameter. The laser cleaning equipment first approaches through the second nylon guide ring, uses the first nylon ring and the roller circular surface for initial positioning, and then the positioning universal ball and the roller cylindrical surface are positioned more accurately. Among them, the first nylon ring also plays a role in protecting the roller surface, preventing the edges and corners on the positioning universal ball from scratching the roller surface.

[0063] In one embodiment, the first center surface alignment mechanism further includes a first laser sensor disposed on the first positioning ring; and the positioning universal ball can rotate 360 ​​degrees.

[0064] In this embodiment, the ball on the positioning universal ball part can rotate 360 ​​degrees, has low cost of use, is easy to replace, and has low friction, so that the laser cleaning equipment changes from sliding friction to rolling friction on the cylindrical surface of the roller.

[0065] In one embodiment, the second center surface alignment mechanism comprises:

[0066] A second positioning ring;

[0067] Two third nylon introduction rings are respectively arranged on the upper part of the second positioning ring and the lower part of the second positioning ring, and are both located outside the second positioning ring; namely, the upper third nylon introduction ring 9 and the lower third nylon introduction ring 8 respectively.

[0068] Two movable universal balls are respectively arranged at the upper part of the first positioning ring and the lower part of the second positioning ring, and are both located inside the second positioning ring, namely, the first movable universal ball 10 and the second movable universal ball 6.

[0069] When the laser cleaning equipment slides on the cylindrical surface of the roller to the second center surface alignment mechanism, the second center surface alignment mechanism is provided with two third nylon guide rings at the top and bottom, a steel movable universal ball and a second laser sensor. The laser cleaning equipment contacts the third nylon guide ring, and the circle diameter of the third nylon guide ring centering adjustment is larger than the circle diameter of the fixed steel universal ball contact roller centering adjustment, which facilitates the roller to enter the second centering surface. The circle diameter of the third nylon guide ring centering adjustment is smaller than the movable universal ball assembly, so that the third nylon guide ring protects the surface of the roller and the movable universal ball assembly, preventing the movable universal ball assembly from scratching the roller surface.

[0070] In one embodiment, the diameter of the circle formed by the two third nylon introduce rings is larger than the diameter of the circle aligned with the two positioning universal balls; the diameter of the circle when the two movable universal balls are not in contact with the roller is smaller than the diameter of the circle aligned with the two positioning universal balls, and when the roller is introduced through the third nylon introduce ring and contacts the spherical surface of the movable universal balls, the roller squeezes the two movable universal balls, and the movable universal balls are compressed to form a reverse force, so that the laser cleaning equipment automatically aligns with the roller.

[0071] Through the fixed universal ball on the first centering surface and the movable universal ball on the second centering surface, the laser cleaning equipment is automatically centered and its center is aligned with the center of the roller.

[0072] In this embodiment, there are various structural forms of the movable universal ball. For example, in one embodiment, the movable universal ball 6 includes a fixed block 61, a ball 63, and a compression spring 64 abutting between the ball 63 and the fixed block.

[0074] The universal ball fixing block can be matched with the threaded steel universal ball body and can slide in the round hole on the ball fixing block. The outer diameter of the large washer is larger than the diameter of the round hole on the universal ball fixing block. The large washer is installed on the threaded steel universal ball and is tightened into one piece through the threads. One side of the compression spring is installed on the large washer and the other side is installed on the cover plate. The cover plate is fixed to the universal ball fixing block by screws, so that the threaded steel universal ball can only move in the cavity of the universal ball fixing block. The reaction force of the compressed compression spring acts on the large washer and the cover plate 62, so that the threaded steel universal ball is always ejected and pressed against the circular surface of the inner cavity of the universal ball fixing block.

[0075] The fixed universal ball assemblies are arranged on both sides above when the laser cleaning equipment clamps the roller, and the movable universal ball assemblies are arranged on both sides above and below when the laser cleaning equipment clamps the roller, to ensure the reliability of automatic centering of the equipment.

[0076] In one embodiment, when the circular diameter of the two movable universal ball contact rollers adjusted by centering is equal to the circular diameter of the two positioning universal ball contact rollers adjusted by centering, the compression amount of the spring is half of the difference between the circular diameter of the two positioning universal ball contact rollers adjusted by centering and the circular diameter of the two movable universal ball contact rollers adjusted by centering.

[0077] In this embodiment, the first centering surface and the second centering surface are provided with a first laser sensor 5 and a second laser sensor 7, which respectively measure the distance between the laser cleaning device and the roller circle. When the deviation between the two does not meet the requirements, the laser cleaning equipment needs to be re-clamped to ensure the accuracy of the automatic centering of the laser cleaning device.
