Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of chemical fiber industry, specifically relates to a laser roll cleaning automatic centering equipment and laser roll cleaning equipment. BACKGROUND

[0002] When using the laser cleaning equipment of the spinning roller, due to the high position of the roller, the narrow space of the workshop, and the use of the crane by the personnel to carry the laser cleaning equipment to the vicinity of the roller, the operator needs to install the equipment on the roller manually, and the center of the laser cleaning equipment must be aligned with the center of the roller. Since the clamping jaw of the laser cleaning device is short (too long clamping, and the clamping position cannot be cleaned by laser), the laser cleaning device itself is heavy, and the long-distance cantilever clamping of the jaw alone may not correct the alignment of 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 of the roller to clean the surface of the roller, eccentric clamping may cause the focal length of the laser generator and the surface of the roller to be out of the set range in a certain stroke, resulting in failure of laser cleaning or unsatisfactory cleaning effect. SUMMARY

[0003] The utility model discloses a laser roll cleaning automatic centering equipment for laser cleaning positioning.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0007] A second centering mechanism for automatic centering of the laser cleaning equipment.

[0008] In the utility model, the first centering surface of the laser cleaning equipment bears part of the weight of the laser cleaning equipment through the first centering mechanism, and is preliminarily positioned. 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 angular deviation between the center of the laser cleaning equipment and the center of the roller. Therefore, the second centering surface automatically centers the laser cleaning equipment through the second centering mechanism.

[0009] Preferably, the first centering mechanism comprises:

[0010] A first positioning ring;

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

[0012] A second nylon guide ring is arranged at the lower part of the first positioning ring and outside the first positioning ring.

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

[0014] When the laser cleaning equipment is carried to the vicinity of the roller by external force equipment such as a travelling crane, the operator approaches the second nylon guide ring of the laser cleaning roller automatic centering equipment of the utility model on the laser cleaning equipment to the surface of the roller, and then places the first nylon guide ring on the surface of the roller. At this time, the external force equipment such as the travelling crane lamp is released, and the subsequent laser cleaning equipment is clamped on the surface of the roller by the operator's manpower. The operator pushes the laser cleaning equipment to the roller, and the first nylon guide ring supports the laser cleaning equipment to slide on the surface of the roller. When the fixed steel positioning universal ball on the laser cleaning equipment contacts the surface of the roller, the positioning universal ball supports the laser cleaning equipment to slide on the surface of the roller, and the sliding friction is changed into rolling friction.

[0015] Preferably, the first nylon guide ring has a smaller diameter than the second nylon ring, and the roller has a smaller diameter than the first nylon guide ring. The two positioning universal balls are aligned in a circle with the same diameter as the roller.

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

[0017] The two positioning universal balls are arranged on the upper part of the first positioning ring. The first nylon guide ring is outside the steel universal ball, and the positioning universal ball contacts a circle with the same diameter as the roller. The diameter of the roller is smaller than the diameter of the first nylon guide ring. The first nylon guide ring has a smaller diameter than the second nylon ring. The laser cleaning equipment is first approached via the second nylon guide ring, and then the first nylon ring is used to center and preliminarily position the roller. Then, the positioning universal ball and the surface of the roller are used for accurate positioning. The first nylon ring also protects the surface of the roller to prevent the edges of the positioning universal ball from scratching the surface of the roller.

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

[0019] The spherical ball on the positioning universal ball part can rotate by 360 degrees, has low use cost, is convenient to replace, has small friction, and changes the sliding friction of the laser cleaning equipment on the surface of the roller into rolling friction.

[0020] Preferably, the second median alignment mechanism comprises:

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

[0024] When the laser cleaning equipment slides on the cylindrical surface of the roller to the second centering mechanism, the second centering mechanism is provided with two third nylon guide rings, a movable universal ball made of steel and a second laser sensor. The laser cleaning equipment contacts the third nylon guide ring, the third nylon guide ring is adjusted to a circle with a diameter larger than that of the fixed steel universal ball contacting the roller, so that the roller is conveniently guided into the second centering surface. The third nylon guide ring is adjusted to a circle with a diameter smaller than that of 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 surface of the roller.

[0025] Preferably, the two third nylon guide rings form a circle with a diameter larger than that of the circle aligned by the two positioning universal balls; the two movable universal balls form a circle with a diameter smaller than that of the circle aligned by the two positioning universal balls when the movable universal balls do not contact the roller. When the roller is guided to contact the spherical surface of the movable universal ball through the third nylon guide ring, the roller compresses the two movable universal balls, the movable universal balls are compressed to form a reverse force, so that the laser cleaning equipment is automatically aligned with the roller.

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