Description

Technical Field

[0001] This utility model relates to the technical field of grinding wheel production equipment, and in particular to a marking device for hole rings in the holes of grinding wheels. Background Technology

[0002] A perforated ring is a metal component embedded in the hole of a grinding wheel. It primarily enhances the structural strength and installation stability of the grinding wheel, playing a crucial role, especially in high-speed applications. The perforated ring needs to bear the grinding wheel's production date and trademark. Existing methods include using a stamping die to imprint the production date and trademark onto the surface of the perforated ring, and using a laser to mark the perforated ring.

[0003] The perforated ring has mounting holes for mounting the grinding wheel to external machinery (such as an angle grinder). However, when using a laser to mark the perforated ring, the mark can easily fall onto the mounting holes, resulting in missing information. Summary of the Invention

[0004] To address the problem that existing laser marking devices for hole rings often result in marks falling onto fixed holes, leading to information loss, this invention proposes a hole ring marking device for grinding wheels. During the transport of the hole ring by the conveying mechanism, the flange at the fixed point of the hole ring is blocked when it contacts the guide plate on one side of the conveying mechanism. Driven by the conveying mechanism, the hole ring rotates, thereby adjusting the position of the fixed hole on the hole ring and preventing subsequent laser-marked labels from falling into the fixed hole.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A marking device for hole rings in grinding wheels includes a conveying mechanism, a positioning mechanism, and a laser. The conveying mechanism is used to convey the hole rings. Limiting plates are provided on both sides of the conveying mechanism to limit the conveying of the hole rings on the conveying mechanism. The positioning mechanism is located on one side of the conveying mechanism and is used to position the hole rings on the conveying mechanism. The laser is located above the conveying mechanism, with the output end of the laser facing the conveying mechanism. The hole ring includes an annular portion and a limiting cylinder. The axis of the annular portion coincides with that of the limiting cylinder. The annular portion is open. Both ends of the limiting cylinder are open, and one end of the limiting cylinder is fixed to the opening of the annular portion. A fixing hole is provided on the annular portion. A flange is provided at the fixing hole on the annular portion. The flange is located on the side of the annular portion closer to the limiting cylinder. The end of the limiting cylinder away from the annular portion falls onto the conveying mechanism. A guide plate is provided on one side of the conveying mechanism. The end of the guide plate closer to the conveying mechanism is lower than the annular portion and extends to the lower side of the annular portion to block the flange. The perforated ring on the conveying mechanism is positioned by the positioning mechanism before being marked. When a guide plate is fixed on one side of the conveying mechanism, a limiting plate is on the other side. When the flange at the fixed point of the perforated ring contacts the guide plate, it is blocked. At this time, the annular part of the perforated ring will contact the limiting plate. Driven by the conveying mechanism and limited by the limiting plate, the perforated ring rotates until the flange at the fixed point of the perforated ring no longer contacts the guide plate. Only then can it continue to be transported by the conveying mechanism, thereby completing the positioning of the fixed hole on the perforated ring.

[0007] Preferably, the positioning mechanism includes a position sensor, a cylinder, and a positioning seat. The position sensor and the cylinder are arranged sequentially along the conveying direction of the conveying mechanism. The position sensor is fixed to the conveying mechanism, and the output end of the cylinder is fixedly connected to the positioning seat, which is located between the cylinder and the conveying mechanism. The cylinder and the positioning seat are located directly below the laser output end. When the position sensor detects the perforated ring, the cylinder drives the positioning seat to press against the perforated ring, keeping the perforated ring stationary. At this time, the laser output end marks the perforated ring.

[0008] Preferably, the positioning seat has a groove at one end near the conveying mechanism.

[0009] Preferably, the positioning seat has a guide groove, and the conveying mechanism has a guide rod fixed thereon, the guide rod extending into the guide groove.

[0010] Preferably, a hopper is connected to the output end of the conveying mechanism.

[0011] Preferably, it also includes a vibratory feeder, the output end of which is connected to the input end of the conveying mechanism.

[0012] Preferably, it also includes a cabinet.

[0013] The beneficial effects of this utility model through the above technical solution are as follows:

[0014] 1. In the process of conveying the hole ring by the conveying mechanism of this utility model, when the flange at the fixed part of the hole ring contacts the guide plate on one side of the conveying mechanism, it is blocked. At this time, the annular part of the hole ring will contact the limiting plate on the other side of the conveying mechanism. Under the driving of the conveying mechanism and the limiting action of the limiting plate, the hole ring will rotate, thereby adjusting the position of the fixed hole on the hole ring, realizing the positioning of the fixed hole, and preventing the label printed by the laser from falling into the fixed hole.

[0015] 2. When the position sensor in the positioning mechanism of this utility model senses the perforated ring, the cylinder drives the positioning seat to press against the perforated ring on the conveying mechanism, so that one side of the perforated ring is against the positioning seat and the other side contacts the limiting plate. Then, the laser output end marks the perforated ring that has stopped moving. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] like Figures 1 to 8 As shown, this embodiment provides a hole ring marking device for the hole in a grinding wheel, including a conveying mechanism 1, a positioning mechanism 2 and a laser 3, and also includes a cabinet 7, which includes an upper cabinet and a lower cabinet. The conveying mechanism 1, the positioning mechanism 2 and the laser 3 are all located on the upper side of the lower cabinet and inside the upper cabinet.

[0027] like Figure 3 As shown, the conveying mechanism 1 is used to convey the perforated ring 4. The conveying mechanism 1 is fixed to the lower cabinet by a support frame. The conveying mechanism 1 uses a belt conveyor. Limiting plates 5 are provided on both sides of the conveying mechanism 1. The limiting plates 5 are fixed on the frame of the conveying mechanism 1 and are located on both sides of the conveyor belt of the conveying mechanism 1. The limiting plates 5 are used to limit the conveying of the perforated ring 4 on the conveying mechanism 1. The gap between the limiting plates 5 on both sides of the conveyor belt and the perforated ring 4 can be small or they can be in direct contact during the movement of the perforated ring 4.

[0028] During the movement of the perforated ring 4 on the conveying mechanism 1, the perforated ring 4 is first rotated and positioned to prevent the labels printed by the laser 3 from falling onto the fixed hole 43. Then, the positioning mechanism 2 stops the perforated ring 4 on the conveying mechanism 1, at which point the laser 3 marks it.

[0029] refer to Figures 5-8 The annular ring 4 includes an annular portion 41 and a limiting cylinder 42. The axis of the annular portion 41 coincides with that of the limiting cylinder 42. The annular portion 41 is open. The limiting cylinder 42 is open at both ends and one end is fixed at the opening of the annular portion 41. The annular portion 41 is provided with a fixing hole 43. A flange 44 is provided at the fixing hole 43 on the annular portion 41. The flange 44 is located on the side of the annular portion 41 close to the limiting cylinder 42.

[0030] In this embodiment, four fixing holes 43 are evenly provided on the annular part 41, and each fixing hole 43 is provided with a flange 44. The flange 44 is formed when the fixing hole 43 is opened downward by the hole-opening device. The plate at the fixing hole 43 is damaged, but its edge is still fixed at the fixing hole 43. The flange 44 is formed downward after multiple breaks in the middle. The function of the flange 44 is to directly penetrate into the abrasive of the grinding wheel to prevent the hole ring 4 from rotating and falling off.

[0031] The end of the limiting cylinder 42 away from the annular part 41 falls onto the conveying mechanism 1. A guide plate 11 is provided on one side of the conveying mechanism 1. The end of the guide plate 11 near the conveying mechanism 1 is lower than the annular part 41 and extends to the lower side of the annular part 41 to block the flange 44.

[0032] In this embodiment, the guide plate 11 is fixed on the frame of the conveying mechanism 1. The guide plate 11 is located between the limiting plates 5 on one side of the conveying mechanism 1. The guide plate 11 is a rectangular plate.

[0033] refer to Figure 7 When the perforated ring 4 is conveyed by the conveying mechanism to a position where one side is a guide plate 11 and the other side is a limiting plate 5, the flange 44 at the fixing hole 43 of the perforated ring 4 is blocked from contacting the guide plate 11. At this time, the annular part 41 of the perforated ring 4 will contact the limiting plate 5. Driven by the conveying mechanism 1 and limited by the limiting plate 5, the perforated ring 4 rotates until the flange 44 at the fixing hole 43 of the perforated ring 4 no longer contacts the guide plate 11, and then it can continue to be transported by the conveying mechanism 1, thereby completing the positioning of the fixing hole 43 on the perforated ring 4 (e.g., Figure 8 As shown, the laser 3 is controlled to mark the position, ensuring that the printed label does not fall onto the fixing hole 43.

[0034] refer to Figure 3 and Figure 4 Furthermore, the positioning mechanism 2 is disposed on one side of the conveying mechanism 1 and is used for positioning the perforated ring 4 on the conveying mechanism 1;

[0035] The positioning mechanism 2 includes a position sensor, a cylinder 21, and a positioning seat 22. The cylinder seat of the cylinder 21 is fixed on the frame of the conveying mechanism 1. The position sensor and the cylinder 21 are arranged sequentially along the conveying direction of the conveying mechanism 1. The position sensor is fixed on the conveying mechanism 1. The output end of the cylinder 21 is fixedly connected to the positioning seat 22, which is located between the cylinder 21 and the conveying mechanism 1. The position sensor can be a proximity switch sensor of model PR12-4DN.

[0036] refer to Figure 4 The positioning seat 22 has a groove 23 at one end near the conveying mechanism 1. The position sensor is set at a set position on the conveying mechanism 1. When it senses the movement of the perforated ring 4 on the conveying mechanism 1, the cylinder 21 drives the positioning seat 22 to press against the perforated ring 4 on the conveying mechanism, so that one side of the perforated ring 4 is against the groove 23 of the positioning seat 22 and the other side contacts the limiting plate 5, thus completing the positioning of the perforated ring 4.

[0037] The positioning seat 22 is provided with a guide groove 24, and the conveying mechanism 1 is fixed with a guide rod 25, which extends into the guide groove 24.

[0038] Furthermore, the laser 3 is positioned above the conveying mechanism 1 and above the positioning seat 22. The output end of the laser 3 faces the conveyor belt of the conveying mechanism 1. In this embodiment, the laser 3 has a set position to ensure that the mark of the laser 3 will not fall into the fixing hole 43 of the perforated ring 4. For example, if the perforated ring 4 is close to the guide plate 11, the fixing hole 43 will not appear when the perforated ring 4 rotates, thus ensuring that the mark of the laser 3 will not fall into the fixing hole 43 of the perforated ring 4.

[0039] In this embodiment, the laser 3 adopts existing technology and can be a fiber optic marking machine of model MZ-FM50-RS1.

[0040] A hopper 12 is connected to the output end of the conveying mechanism 1, and the hopper 12 is fixed at an incline on the frame of the conveying mechanism 1.

[0041] Furthermore, it also includes a vibratory feeder 6, the output end of which is connected to the input end of the conveying mechanism 1. The vibratory feeder 6 ensures that when the annular ring 4 is transported to the conveying mechanism 1, the end of the limiting cylinder 42 on it away from the annular portion 41 falls onto the conveyor belt of the conveying mechanism 1. The vibratory feeder 6 is existing technology and can be a vibratory feeder of model DCZD-YS16503.

[0042] When using this device to mark the perforated ring 4, start the vibratory feeder 6. The vibratory feeder 6 will transport the perforated ring 4 to the input end of the conveying mechanism 1. The vibratory feeder 6 can make the end of the limiting cylinder 42 of the perforated ring 4 away from the annular part 41 fall onto the conveyor belt of the conveying mechanism 1. Then the conveying mechanism 1 starts to work. When the perforated ring 4 is transported by the conveying mechanism 1 to a position where one side is the guide plate 11 and the other side is the limiting plate 5, the flange 44 at the fixing hole 43 of the perforated ring 4 is blocked from contacting the guide plate 11. At this time, the annular part 41 of the perforated ring 4 will contact the limiting plate 5. Under the drive of the conveying mechanism 1 and the limitation of the limiting plate 5, the perforated ring 4 rotates until the flange 44 at the fixing hole 43 of the perforated ring 4 no longer contacts the guide plate 11 and continues to be transported by the conveying mechanism 1.

[0043] When the position sensor detects the moving perforated ring 4 on the conveying mechanism 1, the cylinder 21 drives the positioning seat 22 to press against the perforated ring 4 on the conveying mechanism, so that one side of the perforated ring 4 is against the groove 23 of the positioning seat 22 and the other side contacts the limiting plate 5, thus completing the positioning of the perforated ring 4. At this time, the laser 3 is used to mark the perforated ring 4. After the marking is completed, the cylinder 21 is reset, and the perforated ring 4 can continue to be transported by the conveying mechanism 1. The subsequent marking process of the perforated ring 4 is the same as above.

[0044] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
