Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of hub conveying, in particular to a hub conveying jig for light-curing equipment. Background Art
[0002] The wheel hub is a cylindrical metal component mounted on an axle, supporting the tire's inner profile. It's also called a rim, wheel, or wheel rim. Wheel hubs come in a wide variety of shapes, depending on their diameter, width, molding method, and material. During production, the hub's surface is painted to enhance its aesthetics and corrosion resistance.
[0003] After the wheel hub is painted, it needs to be cured. This is typically done in a drying room or oven. Available paints also include light-curing paints. The wheel hubs are then transferred sequentially to a curing lamp for irradiation and curing. Existing conveyor fixtures are simple, consisting primarily of a conveyor chain with supporting components mounted on it. The wheel hubs are placed directly on the supporting components without any associated fixing structure, resulting in unstable wheel placement. Summary of the Invention
[0004] To address the aforementioned issues, the present invention discloses a hub transfer jig for photocuring equipment, comprising a guide rail, a chain disposed within the guide rail, and connecting plates equidistantly disposed on the chain. A fixed shaft is fixedly connected to each of the connecting plates on either side. Rollers are mounted on the fixed shaft, and the rollers roll against a support surface within the guide rail. Ball bearings are fitted to the ends of the fixed shaft. When the chain is pulled within the guide rail, the rollers roll against the guide rail, while the ball bearings contact the inner wall of the guide rail. This arrangement eliminates contact between the chain and the guide rail, particularly when the guide rail curves, reducing traction resistance and wear.
[0005] A slot is provided in the middle of the upper end of the connecting plate, in which a wheel hub bracket is fitted. The wheel hub bracket includes a column, the upper portion of which is provided with a conical section, and a receiving plate is sleeved on the upper portion of the column. A contact sleeve is fixedly connected to the upper end of the receiving plate. The upper portion of the contact sleeve has a plurality of through holes provided at equal angles, and a top plate is fitted in the through holes. One side of the top plate is inclined and slides with the conical section. A spring ring is sleeved on the upper sidewall of the contact sleeve, and the spring ring is buckled to the outer side of the top plate. The wheel hub is placed on the receiving plate. As the weight of the wheel hub acts on the receiving plate and causes it to move downward, the top plate slides with the conical sleeve as the receiving plate moves downward, moving radially and supporting the wheel hub shaft hole, ensuring the stable fixation of the wheel hub.
[0006] Preferably, a plug rod is fixedly connected to the lower part of the connecting plate, and the plug rod is inserted into the chain. At this time, the function and structure of the plug rod are the same as those on the chain. The purpose of setting this structure is to fixedly connect the connecting plate to the plug rod.
[0007] Preferably, square tubes are fixedly connected to both side walls of the guide rail. An angle steel is fixedly connected to the upper end of the square tube. A limiting wheel is fixedly connected to the lower side wall of the column, and the side wall of the limiting wheel contacts the angle steel. The purpose of setting the angle steel and the limiting wheel is to improve the stability of the hub bracket.
[0008] Preferably, a gear is fixedly connected to the side wall of the column, and a rack is fixedly connected to one of the angle steels. The rack and the gear cooperate. That is, when the hub bracket passes through the rack, under the action of the gear, the hub bracket rotates. At the same time, under the action of the limiting wheel and the angle steel, it is ensured that the gear and the rack can mesh with each other.
[0009] Preferably, a retaining ring is fixedly connected to the middle of the column, and a cylindrical spring is arranged on the retaining ring. The upper end of the cylindrical spring abuts against the lower end of the receiving plate. The purpose of setting the cylindrical spring is to ensure that the receiving plate and the top plate can reset under the action of an external force.
[0010] Preferably, a protective sleeve is fixedly connected to the lower end of the receiving plate, and the protective sleeve is sleeved on the outside of the cylindrical spring. Since the hub is first painted, and the structure where the cylindrical spring is located is relatively complex, it is easy to cause the accumulation of paint and it is not easy to clean, resulting in the reduction or failure of the performance of the cylindrical spring. Therefore, the protective sleeve is set to protect the cylindrical spring.
[0011] The beneficial effects of the present invention are as follows:
[0012] 1. There is a hub bracket, and structures such as a receiving plate and a top plate are arranged at the upper end of the hub bracket. After the hub is placed on the receiving plate, the receiving plate and the top plate move downward together. At the same time, the top plate will radially extend and abut against the inner wall of the hub shaft hole. This structure not only has a simple way to fix the hub, but also ensures the stable and reliable transmission of the hub.
[0013] 2. Structures such as a connecting plate, rollers, and ball bearings are arranged to ensure that the chain does not directly contact the guide rail. That is, through this structure, the chain indirectly realizes rolling cooperation with the guide rail, thereby reducing friction and ensuring the smooth transmission of the hub.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.
[0021] like Figures 1 to 3 As shown, a hub transfer jig for photocuring equipment includes a guide rail 1. The figure only shows a partial structure of the jig. The laying path of the guide rail 1 can be planned according to production needs. A chain 6 is provided inside the guide rail 1. It is a stick-shaped traction structure. Connecting plates 7 are provided at equal distances on the chain 6. Fixed shafts 11 are fixedly connected on both sides of the connecting plate 7. Rollers 10 are provided on the fixed shaft 11, and the rollers 10 roll on the support surface inside the guide rail 1. When the connecting plate 7 is subjected to force, the force can be transferred to the guide rail 1 through the rollers 10, reducing the impact on the chain 6. Balls 12 are provided at the end of the fixed shaft 11. At the bend of the guide rail 1, the balls 12 contact the inner wall of the guide rail 1 to ensure that the chain 6 does not contact the inner wall of the guide rail 1. In summary, the provision of rollers 10 and balls 12 can ensure that the chain 6 does not contact the guide rail 1, reduce resistance, and ensure smooth traction of the chain 6.
[0022] The upper middle part of the connecting plate 7 is provided with a slot 9, and a hub bracket 4 is fitted in the slot 9. Specifically, the lower end of the hub bracket 4 is inserted into the slot 9. Further, an end face bearing can be provided between the slot 9 and the hub 4. The hub bracket 4 includes a column 41. The upper part of the column 41 is provided with a conical section 46. A receiving plate 48 is sleeved on the upper part of the column 41. The hub is placed on the receiving plate 48. The upper end of the receiving plate 48 is fixedly connected with a contact sleeve 49. That is, the contact sleeve 49 is inserted into the shaft hole of the hub, and the diameter of the contact sleeve 49 is slightly smaller than the inner diameter of the hub shaft hole. A plurality of through holes are equiangularly provided in the upper part of the contact sleeve 49, and a top plate 410 is fitted in the through holes. One side of the top plate 410 is inclined and is in sliding fit with the conical section 46. When the top plate 410 slides on the conical section 46, it can extend out of the through hole. Specifically, when the hub is placed on the receiving plate 48, the receiving plate 48 moves downward under the gravity of the hub and pulls the top plate 410 to move downward. At this time, while the top plate 410 moves downward, it also radially extends, so that one side of the top plate 410 abuts against the hub, improving the firmness of the hub fixation.
[0023] A spring ring 411 is sleeved on the upper side wall of the contact sleeve 49, and the spring ring 411 is buckled on the outside of the top plate 410. The spring ring 411 is formed by connecting the heads and tails of ordinary springs. After the hub is removed from the hub bracket and the receiving plate 48 is reset, the top plate 410 can also be reset under the action of the spring ring 411. In addition, the use of similar structures such as the spring ring 411 is not limited, for example, a rubber ring.
[0024] The lower part of the connecting plate 7 is fixedly connected with a plug rod 8, and the plug rod 8 is inserted into the chain 6. The structure of the plug rod 8 is the same as that of the pin shaft of the chain 6. Here, the plug rod 8 is fixedly connected to the connecting plate 7, aiming to install the connecting plate 7 on the chain 6.
[0025] Rectangular tubes 2 are fixedly connected to both side walls of the guide rail 1 by welding. An angle steel 3 is fixedly connected to the upper end of the rectangular tube 2. The rectangular tube 2 and the angle steel 3 form a guardrail. A limiting wheel 42 is fixedly connected to the lower side wall of the column 41, and the side wall of the limiting wheel 42 contacts the angle steel 3. Through this structure, it is ensured that the hub bracket 4 has at least two support points, improving the stability of the support of the hub bracket 4 and the determination of the position.
[0026] A gear 43 is fixedly connected to the side wall of the column 41, and a rack 5 is fixedly connected to one of the angle steels 3. The rack 5 is in cooperation with the gear 43. When the hub bracket 4 passes through the area of the rack 5, under the cooperation of the gear 43, the hub bracket 4 rotates, ensuring that the paint on the surface of the hub can be uniformly cured.
[0027] A retaining ring 44 is fixedly connected to the middle of the column 41. A cylindrical spring 45 is provided on the retaining ring 44, and the upper end of the cylindrical spring 45 abuts against the lower end of the receiving plate 48. The cylindrical spring 45 is used for the reset of the receiving plate 48. That is, after the hub is removed from the receiving plate 48, the compressed cylindrical spring 45 releases elastic potential energy and pushes the receiving plate 48 back to its original position.
[0028] A protective sleeve 47 is fixedly connected to the lower end of the receiving plate 48. The protective sleeve 47 is sleeved on the outside of the cylindrical spring preventing the cylindrical spring 45 from being damaged and ensuring the cleanliness of the area where the cylindrical spring 45 is located.
[0029] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
