Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a ring-shaped support. Background Technology

[0002] During manufacturing, transportation, or assembly, ring-shaped components often experience ellipticity deviations or localized deformations in their inner diameter due to uneven stress, thermal expansion and contraction, or process deviations, affecting their fitting accuracy and assembly quality. This is especially true for components requiring high roundness fits, such as pipe flanges, bearing rings, and mechanical rings; without effective roundness correction, product performance and lifespan will be directly impacted.

[0003] However, existing devices generally suffer from complex structures, poor adjustment synchronization, and loose connections between components that can lead to insufficient alignment accuracy. Furthermore, most support blocks employ a fixed structure, making replacement of parts cumbersome and unsuitable for use with ring-shaped parts of varying sizes. In addition, the sliding fit between the support block and the guide mechanism lacks a reasonable guiding structure, and the stability and repeatability of the alignment process need improvement.

[0004] Therefore, there is an urgent need for a ring-shaped support that is compact, stable in operation, has replaceable parts, and is highly adaptable, in order to improve the quality of ring-shaped component calibration and the ease of use of the device. Utility Model Content

[0005] To overcome the shortcomings of the prior art, the technical problem to be solved by this utility model is to propose a ring-shaped support seat, which adopts the following technical solution:

[0006] A ring-shaped support base, including

[0007] A support assembly, wherein a plurality of guide sleeves are provided annularly and evenly distributed on the sidewall of the support assembly, and the guide sleeves are provided radially along the support assembly, and a guide member is slidably provided inside the plurality of guide sleeves, and a support block is fixedly provided on the outer side of the guide member.

[0008] A screw is vertically disposed inside the support assembly and can rotate relative to the support assembly. A movable block is threadedly connected to the screw.

[0009] The transmission rod has two ends that are rotatably connected to the moving block and the guide member, respectively. When the screw rotates, the moving block moves up or down along the screw, causing the guide member to slide inward or outward within the guide sleeve, thereby causing the support block to move inward or outward.

[0010] As a further improvement, the upper and lower ends of the screw are respectively provided with threaded sections with opposite directions of rotation, and the two threaded sections are respectively threadedly connected to the moving block.

[0011] As a further improvement, the support assembly includes a housing, the housing is provided with an upper bracket and a lower bracket, the guide sleeve is provided on the side wall of the housing, the upper bracket and the lower bracket are provided with bearing seats, and the screw is rotatably connected to the bearing seats.

[0012] As a further improvement, the middle part of the screw is provided with a limiting part for abutting the moving block, and the upper and lower sides of the limiting part are respectively provided with threaded sections with opposite directions of rotation.

[0013] As a further improvement, the aforementioned housing is a hollow cylinder, and the aforementioned housing is provided with three guide sleeves at equal intervals along the axial direction.

[0014] As a further improvement, the cross-sections of the aforementioned upper and lower supports are Y-shaped.

[0015] As a further improvement, the drive end of the screw extends to the outside of the upper bracket for connecting to the drive motor.

[0016] As a further improvement, the aforementioned support block includes a connecting plate and a supporting circular plate. The connecting plate is fixed to the outside of the aforementioned guide member by bolts, and the outer periphery of the aforementioned supporting circular plate is an arc surface.

[0017] As a further improvement, reinforcing plates are provided on both sides of the aforementioned connecting plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Firstly, the annular component alignment support provided by this utility model uses multiple guide sleeves radially arranged on the side wall of the support assembly. A guide component is slidably fitted inside each guide sleeve, and a support block is fixed to the outside of the guide component. A vertically arranged screw drives the moving block to move up and down. A transmission rod structure converts the axial displacement of the screw into synchronous radial movement of each support block, thereby achieving precise and stable alignment of the inner wall of the annular component. This structure is simple, transmits force synchronously, effectively prevents support block offset, and ensures that each support block maintains uniform and synchronous opening and closing movements during the alignment process, thus improving the roundness consistency and stability of the annular component alignment.

[0020] Secondly, this utility model restricts the rotation of the moving block on the screw by using a guide sleeve and a guide component. There is no need to set a separate guide groove for the moving block, resulting in a compact overall structure. At the same time, the upper and lower ends of the screw are respectively provided with threaded sections with opposite directions of rotation, which can drive two moving blocks to move in opposite directions at the same time. This improves the adjustment response speed and support efficiency, and can also distribute the support load during operation, avoiding stress concentration caused by force transmission from a single moving block. This effectively reduces the risk of damage to the guide components and support blocks, and extends the service life of the device.

[0021] Thirdly, in this utility model, the shell is a hollow cylinder with three guide sleeves evenly distributed around its circumference, exhibiting good structural symmetry and balance. The support block is a replaceable, split structure, enhancing the equipment's versatility and ease of maintenance. The outer edge of the support plate is arc-shaped, allowing for large-area contact with the inner wall of the annular component during tensioning, effectively expanding the stress-bearing area. Simultaneously, reinforcing plates on both sides of the connecting plate increase structural strength, enhancing the overall support block's resistance to deformation and load-bearing capacity. This ensures stable operation of the device under high-load, high-frequency usage scenarios, making it suitable for precision straightening of various specifications of annular components and industrial batch operations.

[0034] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0035] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. The terms "part," "side," "end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model.

[0036] For ease of understanding, before describing the technical solution of this application, let's first discuss... Figure 3 The automatic collar alignment device shown includes a alignment station 100 and a conveying station 200. The alignment station 100 has a workpiece base 110 for placing the ring-shaped part 300. An alignment component is mounted on the workpiece base 110, comprising several support blocks 121 and screws 122 for driving the support blocks 121 to open or close. A drive motor 130 is mounted above the alignment station 100, and the drive motor 130 is connected to the drive end of the screws 122 via a lifting mechanism. The conveying station 200 is equipped with a clamping assembly for picking up and placing the ring-shaped part 300. The clamping assembly includes a lifting platform 211, which has a laterally sliding guide plate 212 and a gear motor 213. The guide plate 212 has a rack 214 meshing with the output gear of the gear motor 213, and a clamp 215 for clamping the ring-shaped part 300.

[0037] In one specific embodiment, a conveying station 200 is provided before and after the calibration station 100. The upstream conveying station 200 is used to transport the annular part 300 to be calibrated to the clamping position, and the downstream conveying station 200 is used to remove the calibrated annular part 300 from the calibration station 100 and transport it to the next process or for integration and collection. More specifically, the conveying station 200 includes a frame with a conveyor belt for transporting the annular part 300 to be calibrated or the calibrated annular part 300. A lifting motor is further provided on the frame to drive the lifting platform 211 to move up and down in the vertical direction. The lifting platform 211 is provided with a guide rail, and the aforementioned guide plate 212 is slidably disposed on the guide rail. A gear motor 213 is further provided on the lifting platform 211, with a gear at its output end. When activated, the gear rotates. A rack 214 is horizontally arranged on the upper surface of the guide plate 212. The gear of the gear motor 213 is placed horizontally and meshes with the teeth on the rack 214 of the guide plate 212. After the gear motor 213 is activated, the guide plate 212 moves back and forth along the guide rail under the action of the gear, specifically, it moves back and forth between the conveying station 200 and the support station 100. Furthermore, a clamp 215 for clamping the annular part 300, such as a cylinder-driven double-plate clamp 215, is fixed on the guide plate 212 to clamp the outer periphery of the annular part 300, which will not be described in detail here. Under the coordination of the existing control system, the fixture 215 clamps the ring part 300 to be corrected at the upstream conveying station 200. Through the movement and lifting action of the guide plate 212, the ring part 300 is accurately placed on the workpiece base 110 of the support station 100. After the support is corrected, the ring part 300 is transferred from the support station 100 to the downstream conveying station 200 through similar steps, so as to realize the fully automatic gripping, positioning, support and transfer of shaft and ring type workpieces.

[0038] Based on the above, such as Figures 1-2 As shown, this application provides a support for an annular component, including a support assembly, the aforementioned screw, and a transmission rod. The support assembly has a plurality of guide sleeves evenly distributed annularly on its sidewalls, extending radially along the support assembly. Guide members are slidably disposed within the guide sleeves, and support blocks are fixed to the outer sides of the guide members. The screw 122 is vertically disposed inside the support assembly and is rotatable relative to the support assembly; a movable block is threaded onto the screw. The two ends of the transmission rod 126 are respectively rotatably connected to the movable block 127 and the guide member 125, respectively.

[0039] Specifically, the support assembly includes a housing 123, with a plurality of guide sleeves 124 evenly distributed in a ring on the sidewall of the housing 123. Guide members 125 are slidably arranged radially inside each of the guide sleeves 124. A movable block 127 is threadedly connected to a screw 122. It also includes a transmission rod 126, with both ends hinged to the movable block 127 and the guide member 125 respectively. Rotation of the screw 122 causes the movable block 127 to move upwards or downwards along the screw 122, driving the guide member 125 to slide inwards or outwards within the guide sleeve 124, thereby causing the support blocks 121 to move inwards or outwards, i.e., the multiple support blocks 121 may move closer together or separate from each other.

[0040] In one embodiment, the housing 123 is a hollow cylindrical structure with a screw 122 vertically arranged inside. The transmission rod 126 has connecting ears vertically arranged at both ends, which are hinged to the moving block 127 and the guide member 125. When the moving block 127 moves up and down, the transmission rod 126 can generate a pulling force or a pushing force on the guide member 125, causing the guide member 125 to slide inward or outward inside the guide sleeve 124. As an optional embodiment, the guide sleeve 124 is a cuboid through groove, and the guide member 125 is a cuboid or cylinder of a corresponding size. The inner side of the guide member 125 is hinged to the transmission rod 126, and the outer side is detachably fixed with a support block 121. In the above structure, due to the cooperation between the guide 125 and the guide sleeve 124, plus the vertically arranged connecting lug of the transmission rod 126, the rotation of the moving block 127, the transmission rod 126, and the guide 125 around the screw 122 is restricted, eliminating the need to set a guide mechanism for the moving block 127, and the overall structure is simpler.

[0041] Furthermore, preferably, the upper and lower ends of the screw 122 are respectively provided with threaded sections with opposite directions of rotation, and each threaded end is threadedly connected to a movable block 127. Since the upper and lower threaded ends have opposite directions of rotation, when the screw 122 rotates, the upper and lower movable blocks 127 will move closer or further away from each other, thereby simultaneously driving the multiple transmission rods 126 connected to them to move synchronously. This causes each guide member 125 to contract inward or open outward in the radial direction, thereby realizing the synchronous opening and closing of multiple support blocks 121, completing the tightening, correction or release action of the annular member 300, avoiding the stress concentration problem caused by the force transmission of a single movable block 127, effectively reducing the risk of damage to the guide components and support blocks 121, improving the accuracy of mechanical operation, and extending the service life of the device.

[0042] In the above embodiment, a limiting part 122a is provided in the middle of the screw 122. The upper and lower sides of the limiting part 122a are respectively provided with threaded sections with opposite directions of rotation, which are threadedly connected to the upper and lower moving blocks 127 respectively. This structure, while achieving bidirectional drive, uses the limiting part 122a as an intermediate barrier to ensure that the two moving blocks 127 move axially only on their respective independent threaded sections, preventing interference or offset of the upper and lower moving blocks 127 due to excessive travel.

[0043] On the other hand, preferably, the sidewall of the housing 123 is provided with three guide sleeves 124, which are arranged at 120° intervals on the same horizontal plane, forming a three-point balanced support for the annular part 300 during the correction process. Each guide sleeve 124 has a radially slidable guide member 125, and a support block 121 is fixed to the outside of the guide member 125, which extends inward or outward under the drive of the moving block 127 to cooperate with the inner wall of the annular part 300 for radial tightening correction. The three-point layout effectively suppresses the risk of eccentricity caused by single or double points, making the force on each point more uniform during the correction process, ensuring that the geometry of the annular part 300 achieves accurate circularity under the synchronous action of multiple points, which is beneficial to improving correction accuracy and consistency. Furthermore, the three-point layout also facilitates the positioning of the annular part 300, making it easier for automated identification and clamping.

[0044] like Figure 1 As shown, the support block 121 includes a connecting plate 121a and a supporting circular plate 121b. The inner side of the connecting plate 121a is detachably fixed to the outer side of the guide member 125 by bolts. The supporting circular plate 121b is connected to the outer end of the connecting plate 121a, and its outer edge contour is an arc surface structure. This arc surface can fit tightly against the inner wall of the annular member 300 to achieve a uniform and stable support effect. Furthermore, to enhance the connection stability and overall torsional stiffness between the connecting plate 121a and the guide member 125, reinforcing plates 121c are respectively provided on both sides of the connecting plate 121a. The reinforcing plate 121c is preferably an L-shaped or triangular rib structure, which can resist the reaction force generated by the supporting circular plate 121b during the expansion process, and improve the stability and durability of the connector under stress.

[0045] like Figure 2 and Figure 4 As shown, an upper bracket 128 and a lower bracket 129 are fixed at the upper and lower ends of the housing 123, respectively. A screw 122 is rotatably connected to the upper bracket 128 and the lower bracket 129, and the driving end of the screw 122 extends to the upper end of the upper bracket 128.

[0046] In one specific embodiment, the upper support 128 and the lower support 129 are each provided with a bearing seat 128a, and the screw 122 is rotatably connected to the bearing seat 128a. The driving end of the screw 122 extends upward, passes through the upper support 128 and protrudes to its top, for connection with the drive motor 130 located above the alignment station 100.

[0047] In a preferred embodiment, the upper support 128 and the lower support 129 have Y-shaped cross-sections, providing stable three-dimensional support for the housing 123 and dispersing the mechanical stress on the housing 123 when the screw 122 rotates or the guide 125 extends or retracts. Furthermore, the workpiece base 110 is provided with an insert groove 111 that matches the shape of the lower support 129, used to achieve limited assembly and stable positioning of the support component in the support station 100.

[0048] like Figures 4-5 As shown, the workpiece base 110 is provided with a plurality of support columns 112. The support columns 112 have mounting grooves. A support block 113 is hinged in the mounting groove. The support block 113 includes a support part 113a and a clamping part 113b. The annular member 300 is placed on the support part 113a, driving the support block 113 to rotate inward, thereby causing the clamping part 113b to abut against the side wall of the annular member 300.

[0049] In one specific embodiment, a torsion spring is provided at the hinge of the support block 113 to drive the support block 113 to rotate outward. A stop bar 114 is provided in the mounting groove to prevent the support block 113 from rotating outward excessively. The angle between the support part 113a and the clamping part 113b is 90°. The clamping part 113b is provided with a protrusion. Under normal conditions, the support block 113 flips outward under the action of the torsion spring and abuts against the stop bar 114. The clamping part 113b is in an open state. When the annular part 300 is placed into the support part 113a of the support block 113, the support block 113 flips inward under the action of gravity. The clamping part 113b flips inward and abuts against the outer wall of the annular part 300, thereby clamping and fixing the annular part 300. Preferably, three equally spaced support columns 112 are provided on the workpiece base 110, which can achieve precise centering while clamping and fixing. When removing it, simply pull the ring 300 upwards by clamping it with the clamp 215 to disengage the clamping part 113b.

[0050] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
