Description

Technical Field

[0001] This invention relates to the field of workpiece support and rotation equipment technology, and specifically to an integral roller frame. Background Technology

[0002] Roller frames are core equipment used in welding, assembly, and inspection processes to support and rotate cylindrical workpieces. Traditional roller frames mostly adopt a split structure, which has many technical defects in actual production applications.

[0003] Insufficient rigidity and strength of the base plate: Traditional base plates are mostly assembled in parts or simply welded, resulting in poor overall rigidity and low strength. Long-term heavy-load operation easily leads to deformation and vibration, directly affecting the workpiece rotation accuracy and operational stability. Complex and long processing cycle of roller brackets: Traditional roller brackets have complex structures, requiring high-end processing equipment and processes, limiting material selection, and resulting in long processing cycles and higher overall manufacturing costs. Low efficiency in hoisting and mold changing: Traditional roller frames lack a dedicated overall hoisting structure. During product changeovers and mold changes, multiple units cannot be hoisted together; each unit must be disassembled, moved, and repositioned for adjustment, resulting in cumbersome operations, long mold changeover times, and severely reduced production efficiency. Inconsistent assembly standards: Traditional structures have scattered assembly standards, making on-site installation and debugging difficult, making it hard to ensure consistency in batch operations and failing to meet the demands of high-precision, high-speed production.

[0004] The aforementioned defects make it difficult for traditional roller frames to meet the high-precision, high-efficiency, and rapid production changeover requirements of modern manufacturing. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides an integral roller frame, including a base plate mechanism, multiple sets of roller mechanisms mounted on the base plate mechanism, and a hoisting mechanism mounted at both ends of the base plate mechanism. The multiple sets of base plate mechanisms are connected to each other through the hoisting mechanism. The invention also includes a hoisting beam mechanism for hoisting multiple connected base plate mechanisms.

[0006] Preferably, the base plate mechanism includes a base plate body, a front side plate is installed on one side of the base plate body along the width direction, a rear side plate is installed on the other side of the base plate body along the width direction, and end plates are installed on both sides of the base plate body along the length direction. The front side plate, the rear side plate, and the two end plates form a groove structure on the upper surface of the base plate body.

[0007] Preferably, multiple horizontal stiffeners are provided within the groove structure, with the bottom end of the horizontal stiffeners fixedly connected to the base plate body, one end of the horizontal stiffeners fixedly connected to the front side plate, and the other end of the horizontal stiffeners fixedly connected to the rear side plate.

[0008] Preferably, multiple reference blocks are installed on the outer side of the front or rear side plate, and a slot structure is provided on the outer end of the reference blocks.

[0009] Preferably, the lifting beam mechanism includes a beam body, and the top of the beam body is provided with a plurality of lifting holes arranged in an array.

[0010] Preferably, multiple lifting clamps are arranged at the lower end of the crossbeam body, and each lifting clamp is equipped with a lifting pin. The lifting clamps are used to connect the lifting mechanism, and the lifting mechanism is connected to the lifting clamps through the lifting pins.

[0011] Preferably, the distance between two adjacent lifting clamps is the same as the distance between two adjacent lifting mechanisms.

[0012] Preferably, the hoisting mechanism includes two vertical support plates, a horizontal support plate is set between the two vertical support plates, and two vertical support plates are welded to both ends of the horizontal support plate to form a frame structure.

[0013] Preferably, the lower end of the vertical support plate is provided with multiple fixing holes. One vertical support plate is fixedly connected to the front side plate through fixing holes and bolts, and the other vertical support plate is fixedly connected to the rear side plate through fixing holes and bolts. This design connects the hoisting mechanism as a whole with the base plate mechanism.

[0014] Preferably, one of the roller mechanisms includes two roller brackets. One roller bracket is fixedly connected to the front side plate, and the other roller bracket is fixedly connected to the rear side plate. An installation groove is provided inside the roller bracket, and an upper bearing seat is installed in the installation groove. An upper bearing is installed in the upper bearing seat and is used to connect the upper roller. A lower bearing seat is provided below the upper bearing seat, and a lower bearing is installed in the lower bearing seat and is used to connect the lower roller. The lower roller is located below the upper roller.

[0015] The technical effects and advantages of this invention are as follows: 1. In this integral roller frame, the design of the base plate mechanism has better overall rigidity and strength than the traditional roller frame base plate, making it easy to hoist as a whole. When changing products and changing molds, multiple sets of base plate mechanisms are connected end to end, and then connected to multiple hoisting mechanisms through a hoisting beam mechanism, so as to hoist multiple sets of base plate mechanisms as a whole, shortening the mold change time.

[0016] 2. In this invention, the base plate mechanism is integrally welded together from the base plate body, front side plate, rear side plate, end plate, cross stiffener plate and reference block, and then completed by CNC precision machining. Its rigidity and strength are superior to the traditional roller frame base plate, making it easy to hoist as a whole. It is not prone to deformation during hoisting, has high strength, is not easy to deform, has low vibration, and greatly improves the workpiece support accuracy and running stability.

[0017] 3. In this invention, the distance between two adjacent lifting clamps is the same as the distance between two adjacent lifting mechanisms. This means that when connecting the two, only one lifting clamp needs to be aligned with one lifting mechanism before being connected by a lifting pin. All other lifting clamps and lifting mechanisms do not need to be aligned again, thus reducing the installation time of the lifting clamps and lifting mechanisms and reducing the overall lifting time.

[0018] 4. In this invention, the roller bracket adopts a single flat plate structure, the material is readily available, the processing technology is simple, no special equipment is required, the processing cycle is greatly shortened, and the manufacturing cost is effectively reduced while ensuring rigidity and strength.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose. Please see Figure 1 As shown, this embodiment provides an integral roller frame, including a base plate mechanism 1, multiple sets of roller mechanisms 4 installed on the base plate mechanism 1, and a hoisting mechanism 3 installed at both ends of the base plate mechanism 1. The multiple sets of base plate mechanisms 1 are connected to each other through the hoisting mechanism 3. It also includes a hoisting beam mechanism 2 for hoisting multiple connected base plate mechanisms 1.

[0022] In this integrated roller frame, the design of the base plate mechanism 1 has better overall rigidity and strength than that of traditional roller frame base plates, making it easier to hoist as a whole.

[0023] When switching products and changing molds, multiple sets of base plate mechanisms 1 are connected end to end, and then connected to multiple lifting mechanisms 3 through a lifting beam mechanism 2, so as to lift multiple sets of base plate mechanisms 1 as a whole, shortening the mold change time.

[0024] See Figure 2 As shown, the base plate mechanism 1 includes a base plate body 11. A front side plate 12 is installed on one side of the base plate body 11 along the width direction, a rear side plate 13 is installed on the other side of the base plate body 11 along the width direction, and end plates 14 are installed on both sides of the base plate body 11 along the length direction. The front side plate 12, the rear side plate 13 and the two end plates 14 form a groove structure on the upper surface of the base plate body 11.

[0025] Furthermore, multiple horizontal stiffeners 15 are provided within the groove structure. The bottom end of the horizontal stiffener 15 is fixedly connected to the base plate body 11, one end of the horizontal stiffener 15 is fixedly connected to the front side plate 12, and the other end of the horizontal stiffener 15 is fixedly connected to the rear side plate 13. The horizontal stiffeners 15 improve the overall strength of the base plate mechanism 1 and prevent the front side plate 12 and the rear side plate 13 from deforming or displacing during hoisting.

[0026] Furthermore, multiple reference blocks 16 are installed on the outer side of the front side plate 12 or the rear side plate 13. The outer end of the reference block 16 is provided with a slot structure, which is used for backing and clamping.

[0027] The base plate mechanism 1 is integrally welded together by the base plate body 11, the front side plate 12, the rear side plate 13, the end plate 14, the horizontal stiffener plate 15 and the reference block 16, and then completed by CNC precision machining. Its rigidity and strength are superior to the traditional roller frame base plate, making it easy to hoist as a whole. It is not easy to deform during hoisting, has high strength, is not easy to deform, and has low vibration, which greatly improves the workpiece support accuracy and running stability.

[0028] See Figure 3 As shown, the lifting beam mechanism 2 includes a beam body 21. The top of the beam body 21 is provided with a plurality of lifting holes 22 arranged in a row. The bottom of the beam body 21 is provided with a plurality of lifting clamps 23 arranged in a row. Each lifting clamp 23 is equipped with a lifting pin 24. The lifting clamp 23 is used to connect the lifting mechanism 3. The lifting mechanism 3 is connected to the lifting clamp 23 through the lifting pin 24.

[0029] Furthermore, the distance between two adjacent lifting clamps 23 is the same as the distance between two adjacent lifting mechanisms 3, so that when connecting the two, only one lifting clamp 23 needs to be aligned with one lifting mechanism 3 and then connected by the lifting pin 24. All other lifting clamps 23 and lifting mechanisms 3 do not need to be aligned again, which reduces the installation time of the lifting clamps 23 and lifting mechanisms 3 and reduces the overall lifting time.

[0030] Please see Figure 4 As shown, in this embodiment, the hoisting mechanism 3 includes two vertical support plates 31, and a horizontal support plate 32 is provided between the two vertical support plates 31. The two ends of the horizontal support plate 32 are respectively welded to the two vertical support plates 31 to form a frame structure.

[0031] Furthermore, the lower end of the vertical support plate 31 is provided with multiple fixing holes 311. One vertical support plate 31 is fixedly connected to the front side plate 12 through the fixing holes 311 and bolts, and the other vertical support plate 31 is fixedly connected to the rear side plate 13 through the fixing holes 311 and bolts. This design connects the hoisting mechanism 3 as a whole to the base plate mechanism 1.

[0032] Furthermore, the horizontal support plate 32 has a through pin hole 321 for inserting the lifting pin 24. This design facilitates the connection between the horizontal support plate 32 and the lifting clamp 23 and the lifting pin 24.

[0033] Equipped with a dedicated welded base plate mechanism 1 and a hoisting mechanism 3, multiple sets of roller frames can be hoisted together end to end during mold changing, eliminating the need for disassembly, handling, and repeated alignment, significantly shortening mold changing time and improving production line switching efficiency.

[0034] Please see Figure 5-7As shown, a roller mechanism 4 includes two roller brackets 41. One roller bracket 41 is fixedly connected to the front side plate 12, and the other roller bracket 41 is fixedly connected to the rear side plate 13. The roller bracket 41 has an installation groove 411 inside, and an upper bearing seat 44 is installed in the installation groove 411. An upper bearing 45 is installed in the upper bearing seat 44. The upper bearing 45 is used to connect the upper roller 42. A lower bearing seat 46 is provided below the upper bearing seat 44. A lower bearing is installed in the lower bearing seat 46. The lower bearing is used to connect the lower roller 43. The lower roller 43 is located below the upper roller 42.

[0035] A fixing rod 47 is also installed on the roller bracket 41. The upper bearing seat 44 is provided with a fixing seat 441 for the fixing rod 47. The fixing seat 441 is used to connect the fixing rod 47. The fixing rod 47 is connected to an external lifting mechanism, which can adjust the height of the upper bearing seat 44, thereby facilitating the adjustment of the distance between the upper roller 42 and the lower roller 43.

[0036] The roller bracket 41 adopts a single flat plate structure. The materials are readily available, the processing technology is simple, no special equipment is required, and the processing cycle is greatly shortened. While ensuring rigidity and strength, it effectively reduces manufacturing costs.

[0037] The overall structure is adaptable to various sizes of cylindrical workpieces, which can meet the needs of multi-variety, small-batch, high-speed production scenarios, making it more versatile and practical.

[0038] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
