Description

Technical Field

[0001] This utility model relates to the field of parts clamping tools, and more specifically, to a vertical clamping platform for tubular special parts. Background Technology

[0002] In the fields of automated equipment assembly, special pipeline processing, and precision machinery manufacturing, there is a high demand for vertical clamping of special tubular parts (such as multi-section coaxial pipe fittings with different diameters and special pipes with lug supports). These parts typically have three core characteristics: "multi-section coaxial with different diameters," "easily damaged pipe walls," and "strict vertical accuracy must be maintained after clamping." Examples include special fluid pipelines in the aerospace field and corrosion-resistant reducing pipe fittings in chemical equipment. The clamping quality directly determines the accuracy of subsequent welding, inspection, and assembly processes, and even affects the safety performance of the final product.

[0003] However, existing clamping platforms mostly use "single-size clamping components." For special pipe fittings with different diameters, frequent replacement of clamping modules is required, which is not only cumbersome but also introduces positioning errors due to module replacement. Moreover, traditional clamping relies on manual visual adjustment of the part's perpendicularity. Even with a simple guide structure, the part is prone to tilting due to "ear plate fixing position deviation" and "uneven clamping force." In addition, when the position and size of the ear plates of the tubular parts change (e.g., the ear plate spacing deviation between different batches of parts is ±2mm), the fixing structure of the existing clamping platform cannot be quickly adjusted. The positioning holes need to be re-machined or the support components replaced, resulting in a long adjustment cycle (usually 2-4 hours), which seriously affects production efficiency and makes it difficult to adapt to the production needs of multiple varieties and small batches.

[0004] Therefore, there is an urgent need for a vertical clamping platform for tubular special parts that can accommodate structures with different diameters, ensure vertical accuracy, protect the surface of parts, and be flexibly adjustable, in order to overcome the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this application is to provide a vertical clamping platform for tubular special parts, which solves the technical problems of "poor adaptability, low vertical accuracy, and low adjustment efficiency" in the existing clamping process of tubular special parts.

[0006] To solve the above-mentioned technical problems, the solution adopted in this application is as follows:

[0007] A vertical clamping platform for tubular special parts is provided for vertically clamping special tubular parts. The special tubular parts are formed by coaxially connecting two tubes, with different diameters of tubes one and two, and an ear plate is provided on the outside of either tube wall. The platform includes a support frame.

[0008] Preferably, the top of the support frame is provided with two shaft fixing seats, which clamp and fix the two ends of the shaft.

[0009] Preferably, the shaft passes through an ear plate for connecting special tubular components.

[0010] Preferably, at least two clamps are arranged vertically on the support frame, and at least one clamp is provided on each of the first and second pipes.

[0011] Preferably, the clamp is connected to the support frame via a lateral displacement adjustment structure.

[0012] Preferably, all the clamps are located on the same axis, and all the clamps are fixedly connected together by a connecting bracket.

[0013] Preferably, the shaft fixing seat includes a shaft seat, which is fixed to the top of the support frame. A shaft cover is provided on the shaft seat, and the sides of the shaft seat and the shaft cover are connected laterally through a shaft hole, which is transitionally fitted with the shaft.

[0014] Preferably, the shaft cover and the shaft seat are connected by threaded screws.

[0015] Preferably, the clamp includes a fixing clamp and a separating clamp.

[0016] Preferably, the axis of the fixing hoop is vertical, and the fixing hoop and the separating hoop are disassembled by threaded screws. Both the fixing hoop and the separating hoop are made of thin metal sheet structure.

[0017] Preferably, the fixing hoop and the separating hoop are provided with multiple screw holes.

[0018] Preferably, a layer of adhesive pad is fixedly adhered to the inner ring surface of the fixing hoop and the separating hoop.

[0019] Preferably, the lateral displacement adjustment structure includes a shaft cylinder.

[0020] Preferably, one end of the shaft cylinder is fixedly connected to the fixing hoop, and the other end of the shaft cylinder is provided with a shaft hole, in which a sliding column slides laterally and is perpendicular to the axis of the shaft rod.

[0021] Preferably, a connecting plate is fixed to the end of the sliding column away from its sliding end. The connecting plate is provided with a waist hole, and a screw passes through the waist hole. The connecting plate is threadedly locked onto the support frame.

[0022] Preferably, the direction of the groove in the waist hole is consistent with the axial direction of the shaft.

[0023] Preferably, a slot is provided at the sliding end where the shaft cylinder connects to the slide column, the slot direction is the axial direction of the shaft cylinder, and the shaft hole inside the shaft cylinder is connected to the outside through the slot.

[0024] Preferably, the end of the axial slot is further provided with a slot, and the slotting direction is radial to the shaft.

[0025] Preferably, the axially slotted shaft is also provided with a threaded hole, which passes through the axial slot and is fitted with a screw.

[0026] Preferably, the bottom of the support frame is provided with locking casters.

[0027] The technical solution of this application has at least the following advantages and beneficial effects:

[0028] This utility model improves the vertical accuracy of the parts after clamping by using the dual constraints of "ear plate positioning + multi-section pipe diameter clamping" and the synchronous adjustment function of the connecting frame, thus avoiding errors caused by manual visual adjustment. At the same time, the transition fit of the shaft fixing seat and the axial limit of the retaining ring further eliminate the lateral and axial positional offset of the parts, ensuring stable clamping accuracy.

[0029] This utility model utilizes a detachable "fixed clamp + separating clamp" structure for the clamps, facilitating quick assembly and disassembly of parts and reducing clamping steps. Furthermore, the clamps employ a thin-sheet metal deformation structure, which can adapt to different pipe diameters (pipe one and pipe two) through its own flexible deformation, eliminating the need to replace the clamping module and solving the compatibility problem of the traditional platform's "one diameter, one clamp" requirement. Simultaneously, all clamps are synchronously adjusted via the connecting frame to ensure the coaxiality of multiple pipe sections, meeting the clamping accuracy requirements.

[0030] This invention utilizes a dual-direction displacement adjustment structure (lateral + axial) in its lateral displacement adjustment structure to quickly adapt to deviations in the ear plate position, thereby improving adjustment efficiency and clamping accuracy. Attached Figure Description

[0039] Example 1

[0040] Please refer to Figure 2 This utility model provides a vertical clamping platform for special tubular parts, used to precisely clamp special tubular parts 1 and keep them in a vertical state. The special tubular part 1 is formed by coaxially connecting tube 11 and tube 2 13, with different diameters, and an ear plate 12 is provided on the outer wall of either tube 11 or tube 2 13.

[0041] For the above-mentioned special tubular component 1, please refer to... Figures 1-3In this embodiment, a support frame 2 is provided, and the bottom of the support frame 2 is equipped with manually braked locking casters 3, which can move the support frame 2 to different working positions. The top of the support frame 2 is provided with two shaft fixing seats 5, which are used to clamp and fix the two ends of the shaft 4. The shaft 4 is used to pass through the ear plate 12 of the special tubular part 1. When the shaft 4 is placed on the shaft fixing seat 5, one end of the ear plate 12 of the special tubular part 1 can be lifted by the shaft 4.

[0042] The shaft fixing seat 5 includes a shaft seat 51, a shaft cover 52, and a retaining ring 53.

[0043] Specifically, the bearing seat 51 is fixed to the top of the support frame 2. The bearing seat 51 is provided with a bearing cover 52. The sides of the bearing seat 51 and the bearing cover 52 are connected by a shaft hole. The shaft hole is fitted with the diameter of the shaft rod 4. When the shaft rod 4 is placed in the bearing seat 51, the bearing cover 52 is covered and the shaft rod 4 is fixed by threaded locking using the threaded screw hole 75 on the bearing cover 52 and the bearing seat 51, thereby fixing the height position of one end of the ear plate 12.

[0044] At both ends of the shaft 4, retaining rings 53 are fixedly sleeved. When the shaft 4 is fixed, the retaining rings 53 are located outside the shaft seat 51 and abut against the shaft seat 51. The retaining rings 53 are used to prevent the shaft 4 from sliding laterally at the shaft seat 51, which would affect the clamping accuracy of the special tubular part 1 on the shaft 4.

[0045] Furthermore, when the special tubular component 1 is fixed by the shaft 4 and the shaft fixing seat 5 at one end of the lug plate 12, the special tubular component 1 may still rotate through the connection between the lug plate 12 and the shaft 4, and the connection between the shaft 4 and the shaft seat 51, causing the special tubular component 1 to deflect at an angle before and after clamping, making it impossible for the special tubular component 1 to maintain a vertical state.

[0046] For the above situation, please refer to Figures 2-5 In this embodiment, a clamp 6 and a lateral displacement adjustment structure 7 are also provided. The clamp 6 is connected to the support frame 2 through the lateral displacement adjustment structure 7. At least two clamps 6 are vertically provided on the support frame 2, and at least one clamp 6 is provided on pipe 11 and pipe 2 13 in the special tubular component 1, so that pipe 11 and pipe 2 13 are respectively fixed to the support frame 2 by the clamps 6.

[0047] Specifically, clamp 6 includes a fixing clamp 61 and a separating clamp 62.

[0048] The fixed clamp 61 is connected to the lateral displacement adjustment structure 7. The axis of the fixed clamp 61 is vertical. The separating clamp 62 is separately set from the fixed clamp 61, and the two are detachable by a threaded screw structure. When clamping the special tubular component 1, first loosen the screw, remove the separating clamp 62, and then fix the ear plate 12. At this time, the worker pushes the first tube 11 or the second tube 13 of the special tubular component 1 so that the first tube 11 and the second tube 13 abut against their corresponding fixed clamp 61. The two fixed clamps 61 can keep the first tube 11 and the second tube 13 in a vertical state. Then, the separating clamp 62 is clamped outside the corresponding first tube 11 or the second tube 13 and locked to the fixed clamp 61 by the threaded screw, thereby clamping the first tube 11 and the second tube 13, so that the entire special tubular component 1 is in a vertical state.

[0049] Preferably, all the fixing clamps 61 are located on the same axis, so as to match the coaxial pipe 11 and pipe 2 13, reducing the occurrence of the clamps 6 being unable to clamp different pipes at the same time.

[0050] Preferably, in actual clamping operations, the diameters of the first tube 11 and the second tube 13 of the special tubular component 1 may change at any time according to production needs, making it difficult for the clamp 6 to tighten the special tubular component 1 with different diameters. Therefore, in this embodiment, both the fixing clamp 61 and the separating clamp 62 are set as thin sheet metal structures, allowing the fixing clamp 61 and the separating clamp 62 to undergo significant deformation and have a certain degree of flexibility. When the diameter of the clamped special tubular component 1 changes, when the clamp 6 tightens the first tube 11 and the second tube 13, its thin sheet metal structure can deform to fit the pipe wall of different diameters, and then tighten through the threaded screw structure on the fixing clamp 61 and the separating clamp 62. (It is worth noting that the fixing clamp 61 and the separating clamp 62 are provided with multiple screw holes 75. When the clamping diameter of the clamp 6 changes, the screws on it can also lock the fixing clamp 61 and the separating clamp 62 through the screw holes 75 at different positions.)

[0051] Preferably, since the outer wall of the special tubular component 1 is easily damaged when the clamp 6 is tightened, a layer of rubber pad 8 is fixedly adhered on the inner ring of the clamp 6 (i.e. the inner ring surface of the fixing clamp 61 and the separating clamp 62). The flexible rubber pad 8 protects the special tubular component 1 and prevents the clamp 6 from directly contacting the pipe wall.

[0052] Furthermore, in actual clamping operations, the position or size of the ear plate 12 on the feature tube may change, which will cause the vertical position of tube 11 and tube 2 13 to change when they are vertically erected after the ear plate 12 is fixed, thus making it impossible to match with the clamp 6.

[0053] In response to the above situation, a lateral displacement adjustment structure 7 is also provided on the support frame 2 to adjust the lateral position of the clamp 6 and match the special pipe fitting 1.

[0054] The lateral displacement adjustment structure includes a shaft cylinder 71, a sliding column 72, a connecting plate 73, a slot 74, and a screw hole 75.

[0055] Specifically, one end of the shaft cylinder 71 is fixedly connected to the fixing hoop 61, and the other end of the shaft cylinder 71 is provided with a shaft hole. A sliding column 72 is slidably inserted in the shaft hole. The sliding direction is transverse and perpendicular to the axis of the shaft rod 4. A connecting plate 73 is fixed to the end of the sliding column 72 away from its sliding direction. The connecting plate 73 is locked to the support frame 2 through a threaded screw hole 75.

[0056] Preferably, when the type of ear plate 12 changes, the operator can adjust the lateral position of the fixing hoop 61 by adjusting the lateral sliding of the adjusting shaft cylinder 71, so as to match the lateral position of pipe one 11 or pipe two 13.

[0057] Please refer to the following: Figure 4 A slot 74 is provided at the sliding end where the shaft cylinder 71 connects to the sliding column 72. The direction of the slot 74 is axial, and the shaft hole inside the shaft cylinder 71 communicates with the external environment through the slot 74. At the end of the axial slot 74, another slot 74 is provided, oriented radially, to increase the deformability of the shaft cylinder 71 at the axial slot 74. A threaded hole 75 is also provided on the shaft cylinder 71 through the axial slot 74, and a screw is fitted onto it (refer to existing coupling structures). After the fixing clamp 61 on the shaft cylinder 71 is adjusted, the operator can tighten the screw. The torque during thread matching reduces the diameter of the shaft hole at the sliding end of the shaft cylinder 71, thereby increasing the frictional resistance between the shaft cylinder 71 and the sliding column 72, achieving fixation between the shaft cylinder 71 and the sliding column 72. (To adjust displacement, simply loosen the screw again.)

[0058] In this embodiment, during the actual clamping process, the ear plate 12 connected to the shaft 4 may be displaced along the axial direction of the shaft 4. In this case, the axial positions of tube 11 and tube 2 13 will also change. To address this, the connecting plate 73 is provided with a waist hole, which is threadedly locked to the support frame 2. When displacement adjustment is required, the screw here is loosened, allowing the connecting plate 73 to be quickly adjusted laterally through the waist hole. The displacement direction is consistent with the axial direction of the shaft 4, thereby adjusting the lateral displacement of the clamp 6 for the movement of the ear plate 12 on the shaft 4.

[0059] Furthermore, since each clamp 6 is equipped with a corresponding lateral displacement adjustment structure 7, the lateral position of each clamp 6 needs to be manually adjusted by the staff during the actual clamping and adjustment process. Manual adjustment will result in low adjustment accuracy. In addition, the clamp 6 itself is a thin metal structure that can follow the deformation of the pipe diameter. This means that during manual clamping, the manual adjustment error is combined with the flexible deformation clamping of the clamp 6. Even if the special pipe part 1 is not kept vertical after clamping, it can still be clamped and fixed, which is difficult to distinguish by the naked eye, thus generating clamping error.

[0060] For the above situation, please refer to Figure 4 and Figure 5 In this embodiment, each fixed clamp 61 is connected to a shaft cylinder 71 by a connecting frame 9, so that when the lateral displacement is adjusted, all the fixed clamps 61 will move synchronously through the connecting frame 9, so that all the clamps 6 are on the same axis. When the fixed clamps 61 on different pipe diameters are matched with the pipe wall, they can maintain coaxiality with the pipe 11 and pipe 13 of the special pipe fitting 1, thereby reducing the error caused by manual clamping and adjustment, and keeping the special pipe fitting 1 in a vertical state after clamping.

[0061] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description. The scope of this utility model is defined by the appended claims.
