Description

Technical Field

[0001] This utility model relates to the field of spray-painted ground rail conveyor technology, and in particular to a positioning connection structure based on the sprocket shaft of a spray-painted ground rail conveyor. Background Technology

[0002] In the spray painting ground rail conveyor line, sprocket shafts are generally equipped with components such as sprockets and bearings. In order to achieve the positioning and installation of sprockets and bearings, current sprocket shafts are generally machined with shaft shoulders, which are used to position the sprockets and bearings.

[0003] While the above-mentioned shoulder-based positioning method is convenient, it still has the following drawbacks:

[0004] First, the sprocket shaft needs to be machined to create a shoulder;

[0005] Second, after the sprocket shaft undergoes shoulder machining, the shaft diameter becomes larger, resulting in waste.

[0006] Third, the use of shoulder positioning results in an overfitting of the sprocket, bearing, and sprocket shaft, making disassembly inconvenient. Utility Model Content

[0007] This disclosure aims to address at least one of the technical problems existing in the prior art or related technologies.

[0008] To this end, this disclosure provides a positioning connection structure for a sprocket shaft of a spray-painted ground rail conveyor line, including a sprocket shaft and a sprocket sleeved on the sprocket shaft. The sprocket is sleeved on the end of the sprocket shaft, and the sprocket shaft and the sprocket are jointly provided with a sprocket positioning plate at their ends. The sprocket positioning plate is fastened to the end of the sprocket shaft by shaft positioning fasteners, and the sprocket is fastened to the sprocket positioning plate by sprocket positioning fasteners arranged circumferentially along the end of the sprocket shaft.

[0009] In one feasible implementation, the sprocket positioning plate is constructed as a rectangular plate with arc-shaped ends at both ends.

[0010] Preferably, the rectangular plate has a central fastening hole in the middle and symmetrical side fastening holes on both sides of the central fastening hole. The central fastening hole is matched with the shaft positioning fastener, and the side fastening holes are matched with the sprocket positioning fastener.

[0011] In one feasible embodiment, the positioning connection structure further includes a frame, a first bearing seat fixing plate mounted on the frame, a first bearing seat mounted on the first bearing seat fixing plate, a first bearing mounted on the first bearing seat, and the inner ring of the first bearing mounted on the sprocket shaft. A positioning ring structure that is attached to the sprocket shaft is also installed on the sprocket shaft. The positioning ring structure is attached to the sprocket shaft and then presses tightly against the end of the first bearing seat to form a positioning of the end of the first bearing seat.

[0012] In one feasible embodiment, the frame is further equipped with a second bearing seat fixing plate, a second bearing seat mounted on the second bearing seat fixing plate, a second bearing mounted on the second bearing seat, and the inner ring of the second bearing is mounted on the sprocket shaft. A positioning ring structure is also installed on the sprocket shaft. The positioning ring structure is mounted on the sprocket shaft and then presses tightly against the end of the second bearing seat to form a positioning of the end of the second bearing seat.

[0013] In one feasible implementation, the positioning ring structure includes a first positioning ring and a second positioning ring arranged symmetrically. The first positioning ring and the second positioning ring are each provided with fastening holes on opposite sides. The fastening holes are arranged along the axial direction of the positioning ring structure and penetrate the ring body.

[0014] In one feasible implementation, the first bearing housing fixing plate and the second bearing housing fixing plate are respectively disposed near both ends of the sprocket shaft.

[0015] In one feasible implementation, a first mounting beam is symmetrically provided on the frame at the position corresponding to the first bearing seat fixing plate to install the first bearing seat fixing plate, and a second mounting beam is symmetrically provided on the frame at the position corresponding to the second bearing seat fixing plate to install the second bearing seat fixing plate.

[0016] The positioning connection structure disclosed herein places the sprocket at the end of the sprocket shaft, and a sprocket positioning plate is provided on both the sprocket shaft and the end of the sprocket. The shaft positioning fastener not only secures the sprocket positioning plate to the sprocket shaft, but also secures the sprocket to the sprocket positioning plate. This achieves the connection of the three components and also realizes the positioning connection of the sprocket.

[0017] Throughout the entire positioning and connection process, there is no need to machine the sprocket shaft shoulder, saving the shoulder machining process and improving processing efficiency;

[0018] This invention eliminates the need for a shoulder on the sprocket shaft, effectively reducing the diameter of the sprocket shaft and saving materials.

[0019] This disclosure uses a sprocket positioning plate and uses positioning fasteners to position and connect the sprocket positioning plate to the sprocket shaft and the sprocket. Compared with the prior art which uses a shaft shoulder, the sprocket adopts an overfit installation mode to the sprocket shaft. In this disclosure, the sprocket and the sprocket shaft can be clearance fitted, which is much more convenient to operate in terms of disassembly and assembly compared to overfitting.

Detailed Implementation

[0028] The technical solutions of specific embodiments of this utility model will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. All other embodiments obtained by those skilled in the art based on the teachings of the following embodiments are within the protection scope of this utility model.

[0029] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and are not limited in number; for example, a first object can be one or more.

[0030] refer to Figure 1-7This utility model provides a positioning connection structure for a sprocket shaft of a spraying ground rail conveyor line, including a sprocket shaft 1 and a sprocket 2 sleeved on the sprocket shaft 1. The sprocket 2 is sleeved on the end of the sprocket shaft 1. The sprocket shaft 1 and the sprocket 2 are jointly provided with a sprocket positioning plate 3 at their ends. The sprocket positioning plate 3 is fastened to the end of the sprocket shaft 1 by a shaft positioning fastener 4. The sprocket 2 is fastened to the sprocket positioning plate 3 by sprocket positioning fasteners 5 arranged circumferentially along the end of the sprocket shaft 1.

[0031] In this disclosure, the sprocket 2 can be fitted onto the sprocket shaft 1 with a clearance fit, which is much simpler to assemble and disassemble compared to the overfitting method used in the prior art. In this disclosure, the sprocket 2 is mounted at the end of the sprocket shaft 1, with the end of the sprocket 2 being substantially flush with the end of the sprocket shaft 1. The sprocket positioning plate 3 is located at the ends of both the sprocket shaft 1 and the sprocket 2, with a portion of the plate covering the end of the sprocket shaft 1 and a portion covering the end of the sprocket 2. The shaft positioning fastener 4 can be replaced by a shaft positioning screw, which tightens the sprocket positioning plate 3 onto the end of the sprocket shaft 1. The sprocket positioning fastener 5 can be replaced by a sprocket positioning screw. This sprocket positioning screw tightens the sprocket positioning plate 3 onto the end of the sprocket 2, thus connecting the sprocket positioning plate 3, the sprocket 2, and the sprocket shaft 1. Since the sprocket positioning plate 3 is located at the end of the sprocket 2 and the sprocket shaft 1, it can position the sprocket 2. At the same time, due to the presence of the sprocket positioning fastener 5, the sprocket 2 can also be positioned and connected to the sprocket positioning plate 3, and finally connected to the sprocket shaft 1.

[0032] As can be seen, in this disclosure, the sprocket shaft 1 can achieve the positioning of the sprocket 2 without the need for shoulder machining, thus solving a series of problems caused by the need for shoulder machining. It should be particularly noted that eliminating the need for shoulder machining on the sprocket shaft effectively reduces the shaft diameter. The main reason is illustrated below. If a sprocket shaft with a shoulder has a large-diameter section and a small-diameter section, and the shoulder is located at the connection between the large-diameter and small-diameter sections, the sprocket is fitted onto the small-diameter section, while the large-diameter section is not fitted with the sprocket. If the shoulder is not provided, the sprocket shaft diameter only needs to be matched to the diameter of the small-diameter section to satisfy the sprocket fitting. In this case, the sprocket shaft with only the small-diameter section diameter has a significantly reduced overall diameter compared to a sprocket shaft with a large-diameter section and a shoulder. Furthermore, sprocket shafts are made with carefully selected and expensive materials; using the sprocket shaft of this disclosure, which eliminates the need for shoulder machining, can save a significant amount of procurement costs.

[0033] In this disclosure, the sprocket positioning plate 3 is constructed as a rectangular plate with arc-shaped ends at both ends. The sprocket positioning plate 3 does not use a structure matching the size and shape of the sprocket 2; instead, it uses a structure smaller and different in shape than the sprocket 2. This achieves the goal of saving materials. Of course, under the premise of saving materials, the sprocket positioning plate 3 of this structure can still meet the main function of positioning and connection. While meeting this main function, the size can be reduced as much as possible, while maintaining the symmetry of the fastening connection and the balance of forces on the fastening connection, with the aim of maintaining the stability of the fastening connection.

[0034] Specifically, in this disclosure, this is achieved primarily through the following method: a central fastening hole 31 is provided in the middle of the rectangular plate, and symmetrical side fastening holes 32 are provided on both sides of the central fastening hole 31. The central fastening hole 31 is fitted with the shaft positioning fastener 4, and the side fastening holes 32 are fitted with the sprocket positioning fastener 5. The symmetrically arranged side fastening holes 32 here achieve stable and secure positioning connection.

[0035] In this disclosure, after solving the positioning connection of the sprocket 2, the positioning connection of the bearing is also considered. Similarly, the positioning connection method of the bearing in this disclosure does not require the sprocket shaft 1 to have a shoulder, nor does it require positioning through the shoulder.

[0036] Specifically, the positioning connection structure further includes a frame 6, a first bearing seat fixing plate 7 mounted on the frame 6, a first bearing seat 8 mounted on the first bearing seat fixing plate 7, a first bearing (not shown) mounted on the first bearing seat 8, and the inner ring of the first bearing mounted on the sprocket shaft 1. A positioning ring structure is also installed on the sprocket shaft 1. After the positioning ring structure is mounted on the sprocket shaft 1, it presses tightly against the end of the first bearing seat 8 to form a positioning of the end of the first bearing seat 8.

[0037] In this disclosure, the frame 6 can be understood as a rectangular frame structure that is erected. The frame 6 is provided with first mounting beams 9 symmetrically at the corresponding positions of the first bearing seat fixing plate 7 to install the first bearing seat fixing plate 7. The shape of the first bearing seat fixing plate 7 is not required, as long as it can be installed on the first mounting beam 9 and at the same time be able to be installed on the first bearing seat 8.

[0038] The first bearing housing fixing plate 7 and the positioning ring structure disclosed herein are mainly used for positioning both ends of the first bearing housing 8. Specifically, the first bearing housing fixing plate 7 positions the upper end of the first bearing housing 8, while the positioning ring structure positions the first bearing housing 8. It should be noted that the first bearing as a whole is located within the first bearing housing 8 and is fixed within the first bearing housing 8 by its outer ring. Positioning both ends of the first bearing housing 8 is equivalent to positioning both ends of the first bearing.

[0039] In this disclosure, in particular, the positioning ring structure is mounted on the sprocket shaft 1 in a clamping manner, which allows for disassembly and assembly, and facilitates the disassembly and assembly of the first bearing. Compared with the prior art, most bearings are mounted on the sprocket shaft 1 by an overfitting method. In this application, the positioning ring structure is used to achieve positioning, making the disassembly and assembly of the first bearing much easier and more convenient.

[0040] In this disclosure, the frame 6 is further equipped with a second bearing seat fixing plate 10, a second bearing seat 11 mounted on the second bearing seat fixing plate 10, a second bearing (not shown) mounted on the second bearing seat 11, and the inner ring of the second bearing mounted on the sprocket shaft 1. A positioning ring structure is also mounted on the sprocket shaft 1, which, after being mounted on the sprocket shaft 1, presses tightly against the end of the second bearing seat 11, thus positioning the end of the second bearing seat 11. The specific arrangement and details are similar to the positioning method of the first bearing seat, and will not be described in detail here.

[0041] Specifically, the positioning ring structure is described in detail below. The positioning ring structure includes a symmetrically arranged first positioning ring 12 and a second positioning ring 13. Both the first positioning ring 12 and the second positioning ring 13 have mating fastening holes 14 on their opposite sides. The fastening holes 14 are arranged axially along the positioning ring structure and penetrate the ring body. Here, the ring body can be understood as either the first positioning ring 12 or the second positioning ring 13. That is, the two positioning rings, when combined, form a clamping effect on the sprocket shaft 1. By screwing screws into the fastening holes 14, the two positioning rings can be tightened onto the sprocket shaft 1, thereby achieving positioning of the bearing seat end.

[0042] It should be noted that in this disclosure, the first bearing seat fixing plate 7 and the second bearing seat fixing plate 10 are respectively arranged close to both ends of the sprocket shaft 1, so as to keep the sprocket shaft 1 under force near the end and make the force as balanced as possible.

[0043] Meanwhile, a second mounting beam 15 is symmetrically provided on the frame 6 at the corresponding position of the second bearing seat fixing plate 10 to install the second bearing seat fixing plate 10.

[0044] As can be seen, the first bearing housing 8 and the second bearing housing 11 are disposed inside the frame 6. The first bearing housing 8 is basically located at the bottom of the top of the frame 6, while the second bearing housing 11 is basically located at the top of the bottom of the frame 6. This creates a symmetrical arrangement at the top and bottom of the frame 6, maintaining a basic symmetrical arrangement and ensuring balanced force during positioning, installation, and connection. Of course, in other embodiments, the frame 6 can also adopt other structures, such as a left-right structure. In this case, the first bearing housing 8 and the second bearing housing 11 are fitted according to the left-right structure, which does not interfere with the scope of protection of the claims of this application.

[0045] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
