Abstract
Description
Technical Field
[0001] This utility model relates to the field of parts clamping tools, and more specifically, to a horizontal clamping platform for tubular special parts. Background Technology
[0002] During the processing, inspection, and assembly of special tubular components (such as multi-channel hydraulic pipes and aerospace-grade irregularly shaped conduits), stable horizontal clamping is required to ensure the accuracy of subsequent welding, flaw detection, flange connection, and other processes. These special tubular components typically consist of a main pipe and two secondary pipes connected to the main pipe but in different axial directions. The main pipe also has lugs for positioning. They have a high degree of structural irregularity and strict dimensional accuracy requirements.
[0003] However, traditional clamping platforms typically use fixed structures for the tube shaft fixing seats, which cannot be adjusted in height or lateral position. When the ear plate dimensions of special tubular components change, or the relative positions of the main and auxiliary tubes change (e.g., differences in ear plate thickness between different product models, adjustments to the auxiliary tube offset angle), or when machining errors cause fluctuations in the vertical distance between the ear plate and the main tube, the fixed tube shaft fixing seats cannot meet the clamping requirements. This necessitates redesigning or replacing the clamping components, increasing production costs and reducing efficiency. Furthermore, the machining (e.g., welding auxiliary tube interfaces) and inspection (e.g., straightness measurement) of special tubular components require extremely high horizontal precision. Traditional platforms only use the tube shaft fixing seats for single-point clamping of the auxiliary tube or shaft, lacking a dedicated horizontal calibration structure for the main tube. This makes the main tube prone to tilting due to uneven weight distribution of the parts and clamping force misalignment, thus affecting machining quality.
[0004] Therefore, there is an urgent need for a horizontal clamping platform for tubular special parts that is highly versatile, has high horizontal clamping accuracy, and is highly controllable, in order to solve the problems existing in the above-mentioned prior art and meet the needs of high-precision machining and efficient production of special tubular parts. Utility Model Content
[0005] The purpose of this application is to provide a horizontal clamping platform for tubular special parts, which solves the technical problems of low versatility and low horizontal clamping accuracy when clamping tubular special parts horizontally.
[0006] To solve the above-mentioned technical problems, the solution adopted in this application is as follows:
[0007] A horizontal clamping platform for tubular special parts is provided for horizontally clamping special tubular parts. The special tubular parts include a main pipe, which is connected to a secondary pipe 1 and a secondary pipe 2 respectively. The pipe length directions of the main pipe and the secondary pipe 1 and the secondary pipe 2 are different. The main pipe is also provided with an ear plate and includes a support frame.
[0008] Preferably, the support frame is equipped with multiple tube shaft fixing seats.
[0009] Preferably, a shaft is fitted onto the ear plate.
[0010] Preferably, the shaft, secondary tube one, and secondary tube two are respectively clamped on corresponding matching tube shaft fixing seats.
[0011] Preferably, the clamping shaft hole of the tube shaft fixing seat is oriented laterally.
[0012] Preferably, the support frame is provided with a horizontal retaining hoop, which includes a clamp and a vertical sliding structure. The clamp has a main pipe and is connected to the support frame through the vertical sliding structure.
[0013] Preferably, the corresponding matching pipe shaft fixing seats of the secondary pipe one and secondary pipe two are set on the vertical displacement adjustment structure.
[0014] Preferably, the tube shaft fixing seat includes a shaft seat.
[0015] Preferably, the bearing seat is installed on the top of the support frame, and a bearing cover is provided on the top of the bearing seat. The bearing cover and the bearing seat share a common shaft hole, the shaft hole is transverse in the axial direction, a bolt is vertically inserted on the bearing cover, and screw holes are provided on the bearing seat correspondingly at the top and bottom.
[0016] Preferably, the diameter of the shaft hole on the bearing seat and the shaft cover matches the diameter of the corresponding clamped secondary tube one, secondary tube two, and shaft rod, and is a transition fit.
[0017] Preferably, retaining rings are also fixedly fitted at both ends of the shaft.
[0018] Preferably, when the special tubular component is clamped by the tube shaft fixing seat, the retaining ring is located outside the shaft seat and abuts against the shaft seat.
[0019] Preferably, a bushing is also fixedly fitted on the inner annular surface of the shaft hole, and the bushing is a flexible sleeve structure.
[0020] Preferably, the clamp is an annular clamp, which consists of two separate semi-annular clamps. Each semi-annular clamp has a locking plate fixedly installed at both ends, and the locking plate has mounting holes.
[0021] Preferably, the vertical sliding structure includes a sliding sleeve and a sliding column.
[0022] Preferably, one end of the clamp is fixedly connected to a sliding sleeve, the sliding sleeve has a sliding hole, and a sliding column is slidably disposed in the sliding hole of the sliding sleeve, the sliding column sliding in a vertical direction.
[0023] Preferably, the end of the sliding column away from the sliding position is fixedly connected to a mounting sheet metal, which is then threadedly locked to the support frame by bolts.
[0024] Preferably, the sliding end of the sliding sleeve connected to the sliding column has an opening, which allows the sliding end of the sliding sleeve to deform, thereby changing the diameter of the internal sliding hole. A bolt is threaded through the opening on the sliding end.
[0025] Preferably, the vertical displacement adjustment structure includes a lead screw.
[0026] Preferably, the top of the lead screw is fixedly connected to the bottom of the shaft seat, the lead screw passes vertically through the support frame and the threaded sleeve, and is threadedly matched with the threaded sleeve. The threaded sleeve is coaxially fixedly connected to the rotating shaft of the motor, and the motor is fixed on the support frame.
[0027] The technical solution of this application has at least the following advantages and beneficial effects:
[0028] This invention uses a horizontal retaining clamp to tighten the main pipe with a ring clamp. The clamp's axis is laterally oriented, which forces the main pipe to remain horizontal. At the same time, after the shaft is positioned by the pipe shaft fixing seat, the swing tendency of the main pipe around the shaft is restricted by the clamp, forming a dual protection structure of "shaft positioning + main pipe horizontal calibration". This effectively avoids the tilting of the main pipe caused by the gravity of the parts or the force of clamping, ensuring the accuracy of subsequent welding, inspection and other processes, and reducing the product defect rate.
[0029] This utility model, by setting a vertical displacement adjustment structure, uses a motor to drive the threaded sleeve to rotate, thereby driving the lead screw and the tube shaft fixing seat to achieve vertical height adjustment. It can adapt to the difference in secondary tube height caused by changes in ear plate size and processing errors of different special tube parts, and can achieve precise clamping of secondary tube 12 and secondary tube 23 without replacing the fixing seat.
[0030] This utility model also enables fine-tuning of the vertical position of the clamp by setting a vertical sliding structure (sliding sleeve and sliding column) for the horizontal retaining clamp. Combined with the horizontally detachable installation design of the mounting sheet metal, the clamp position can be flexibly adjusted according to the horizontal position of the main pipe, adapting to different ear plate and main pipe spacings and different types of special pipe parts, greatly reducing the cost of changing the type and improving the reusability of the platform.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0039] Example 1
[0040] Please refer to Figure 2 This utility model provides a horizontal clamping platform for special tubular parts, which is used to horizontally clamp special tubular parts 1. The special tubular parts 1 include a main pipe 11, and a secondary pipe 12 and a secondary pipe 2 13 that are connected to the main pipe 11 but have different axial directions. The main pipe 11 is also provided with an ear plate 14.
[0041] For the aforementioned special tubular component 11, please refer to... Figures 1-5 In this embodiment, a support frame 2 is provided for installing various structures responsible for clamping the special tubular component 1. A brake caster 3 is fixedly provided at the bottom of the support frame 2. The brake caster 3 is a caster that can be manually locked and braked, which can transport the special tubular component 1, which is horizontally clamped on the support frame 2, to different working positions.
[0042] Furthermore, multiple tube shaft fixing seats 4 are installed on the support frame 2, which respectively clamp the secondary tube 12 and the secondary tube 2 13. A shaft 5 is also fixedly inserted on the ear plate 14 of the main tube 11. Both ends of the shaft 5 are also clamped on the corresponding tube shaft fixing seats 4. The clamping shaft hole of the tube shaft fixing seat 4 is in the horizontal direction, thereby horizontally clamping the special tube part 1 and setting it horizontally.
[0043] The tube shaft fixing seat 4 includes a shaft seat 41, a shaft cover 42, a bolt 43, a shaft sleeve 44, and a retaining ring 45.
[0044] Specifically, the bearing seat 41 is installed on the top of the support frame 2. The top of the bearing seat 41 is provided with a bearing cover 42. The bearing cover 42 and the bearing seat 41 share a common shaft hole. The shaft hole is axially transverse. The bearing cover 42 is vertically provided with a bolt 43. The bearing seat 41 is provided with corresponding screw holes at the top and bottom. When the special tubular component 1 is clamped through the shaft hole on the bearing seat 41 and the bearing cover 42, the clamped special tubular component 1 can be locked by manually tightening the bolt 43.
[0045] It is worth noting that the pipe shaft fixing seats 4, which are respectively provided with secondary pipe 12, secondary pipe 2 13 and shaft 5, have shaft hole diameters on their shaft seat 41 and shaft cover 42 that match the diameter of the corresponding clamped pipe (or shaft 5) and are in transition fit, making it easy to match and clamp them.
[0046] It is worth noting that a bushing 44 is also fixedly fitted on the inner annular surface of the shaft hole. The bushing 44 is a flexible sleeve structure, which is used to prevent the special tubular part 1 from directly contacting the tube shaft fixing seat 4, so as to avoid damage to the surface of the special tubular part 1.
[0047] It is worth noting that retaining rings 45 are also fixedly sleeved at both ends of the shaft 5. When the special tubular part 1 is clamped by the tube shaft fixing seat 4, the retaining rings 45 are located outside the shaft seat 41 and abut against the shaft seat 41 to restrict the clamped shaft 5 from sliding along its axial direction, affecting the clamping effect and subsequent processing work.
[0048] Furthermore, in the actual clamping process, if only one type of special tubular component 1 is used, it is only necessary to accurately set the installation height and position of each tube shaft fixing seat 4 to ensure that the special tubular component 1 is clamped horizontally. However, in reality, the special tubular component 1 will change the size and position of the ear plate 14 and the pipe according to the actual production and installation requirements, making it difficult for the tube shaft fixing seat 4 fixed on the support frame 2 to match different special tubular components 1. Moreover, even for special tubular components 1 of the same shape, there will be machining errors in the positions of various parts (such as ear plate 14). This means that even if the clamping accuracy for horizontally clamping the special tubular component 1 can be guaranteed, it is difficult to maintain the horizontal clamping accuracy due to the machining error of the special tubular component 1 itself.
[0049] In response to the above situation, in this embodiment, a horizontal retaining hoop 6 for maintaining the horizontal state of the special tubular component 1 is also provided on the support frame 2, and a vertical displacement adjustment structure 7 for vertically adjusting the tube shaft fixing seat 4 for changing the horizontal position of the special tubular component 1 is also provided.
[0050] The horizontal retaining clamp 6 includes a clamp 61, a locking plate 62, a sliding sleeve 63, a sliding column 64, a mounting sheet metal 65, and an opening 66.
[0051] Specifically, clamp 61 is clamped onto the wall of the main pipe 11. Clamp 61 is an annular clamp plate, which is composed of two separately set semi-annular clamp plates. Each semi-annular clamp plate has a locking plate 62 fixed at both ends. The locking plate 62 is provided with mounting holes. When the two semi-annular clamp plates are clamped onto the outer wall of the main pipe 11, the workers can tighten the two clamp plates by threading the bolt 43 through the mounting holes of the two semi-annular clamp plates.
[0052] Preferably, the axial direction of the clamp 61 is horizontal. When the main pipe 11 is clamped in the clamp 61, the pipe direction of the main pipe 11 will also be horizontal, so that the clamp 61 can be used to maintain the horizontal state of the main pipe 11 after clamping.
[0053] In addition, one end of the clamp 61 is fixedly connected to a sliding sleeve 63, the sliding sleeve 63 has a sliding hole, and a sliding column 64 is slidably arranged in the sliding hole of the sliding sleeve 63. The sliding direction of the sliding column 64 is vertical. The end of the sliding column 64 away from the sliding position is fixedly connected to a mounting sheet metal 65, and the mounting sheet metal 65 is threadedly locked to the support frame 2 by bolts 43.
[0054] The sliding end of the sliding sleeve 63 connected to the sliding column 64 has an opening 66. The opening 66 allows the sliding end of the sliding sleeve 63 to deform, thereby changing the diameter of the internal sliding hole. A bolt 43 is threaded through the sliding end of the sliding sleeve 63. The size of the opening 66 can be changed by twisting the bolt 43, thereby changing the diameter of the sliding hole and controlling the sliding or locking of the sliding column 64 in the sliding hole.
[0055] Preferably, in this embodiment, the installation process of the special tubular component 1 is as follows: first, the shaft 5 is fixedly sleeved on the ear plate 14, and then the shaft 5 is fixed on the tube shaft fixing seat 4. At this time, the clamping angle of the entire special tubular component 1 will swing about the axis of the shaft 5. Then, the main pipe 11 is clamped and fixed by the clamp 61 so that the main pipe 11 remains horizontal, thereby keeping the entire special tubular component 1 in a horizontal state.
[0056] Preferably, when clamp 61 is installed, if the position or size of ear plate 14 changes, causing a change in the relative distance between main pipe 11 and shaft 5 on ear plate 14, clamp 61 can be adjusted by adjusting the relative sliding position of sliding sleeve 63 and sliding column 64 so that clamp 61 is vertically matched with main pipe 11. The mounting sheet metal 65 can remove bolt 43, adjust the lateral displacement on support frame 2, and then tighten bolt 43 onto support frame 2 by thread, so that clamp 61 is laterally matched with main pipe 11, thereby enabling clamp 61 to adapt to clamp different special pipe parts 1 and keep them horizontal.
[0057] Furthermore, after the special tubular component 1 is horizontally clamped by the shaft 5 and the horizontal retaining clamp 6, it is also necessary to clamp and fix the secondary tube 12 and secondary tube 2 13 of the special tubular component 1 accordingly, so as to distribute the weight of the special tubular component 1 and maintain the clamping stability of the special tubular component 1. However, due to the change of the ear plate 14 of the special tubular component 1, the height of the secondary tube 12 and secondary tube 2 13 will change accordingly after different special tubular components 1 are horizontally clamped (after horizontal clamping, the distance between the ear plate 14 and the main tube 11 is the vertical distance), so the clamping height of the tube shaft fixing seat 4 corresponding to the secondary tube 12 and secondary tube 2 13 also needs to be adjusted accordingly.
[0058] In response to the above situation, in this embodiment, a vertical displacement adjustment structure 7 is also provided on the pipe shaft fixing seat 4 corresponding to the secondary pipe 12 and the secondary pipe 2 13, which is used to adjust the vertical position of the entire pipe seat fixing seat.
[0059] The vertical displacement adjustment structure 7 includes a lead screw 71, a motor 72, and a threaded sleeve 73.
[0060] Specifically, the top of the lead screw 71 is fixedly connected to the bottom of the bearing seat 41. The lead screw 71 passes vertically through the support frame 2 and the threaded sleeve 73, and is connected to the threaded sleeve 73 by thread matching. The threaded sleeve 73 is coaxially fixedly connected to the rotating shaft of the motor 72. The motor 72 is fixed on the support frame 2. When the motor 72 starts, it will drive the threaded sleeve 73 to rotate, causing the lead screw 71 to move vertically, thereby adjusting the bearing seat 41 vertically, so that the shaft holes on the bearing seat 41 and the bearing cover 42 match the horizontally clamped secondary tube 12 and secondary tube 2 13.
[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.
