Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. [[ID=*]]
[0023] Please refer to Figure 1-2 , a quick connector for a clamp flange of the present invention includes: a frame 1. The frame has a "field" - shaped structure, including an outer border 101 and a vertical middle rod 102 and a horizontal middle rod 103 that are perpendicularly and cross - welded to the outer border. Shaft rod fixing blocks 104 are provided at the four corners of the outer border. Among them, the shaft rod fixing block and the outer border are of an integrally formed structure. Limit blocks 2 are provided at both ends of the vertical middle rod. Through holes 3 are opened on both the shaft rod fixing block and the limit block. As Figure 5 shown, during installation, the shaft rod 17 passes through the through hole and the first shaft hole 4 of the clamp, and both ends are fixed and limited by a positioning pin assembly to prevent falling off. Among them, the positioning pin assembly includes positioning holes (not visible in the figure) opened at both ends of the shaft rod 17, a positioning pin fixing seat 5 provided on the shaft rod fixing block, and a positioning pin 6 installed in the positioning pin fixing seat and whose front end can be inserted into the positioning hole. Threaded mounting holes 8 for fixing the clamp flange blind plate 7 are opened on the horizontal middle rod. As Figure 3 shown, lay the frame flat, place the blind plate to be installed into the frame, and lock and fix it from the back by passing two hexagon socket bolts through the threaded mounting holes.
[0024] Specifically, the limit block and both ends of the vertical middle rod are integrally formed. Fixing holes 9 are opened on the limit block. A limit step 91 is provided on the end face of the limit block that contacts the blind plate. A positioning rod 10 for pressing the sealing ring in the blind plate is installed in the fixing hole through two groups of hexagon socket screws 18. The positioning rod is installed in the fixing hole of the limit block through two groups of hexagon socket screws and its end is used to press the sealing ring. As Figure 4 shown, seat the sealing ring 11 into the sealing groove of the blind plate, install the limit block in place and lock it tightly with hexagon socket screws to press the sealing ring to prevent it from shaking and falling off.
[0025] like Figure 5 As shown, the clamp is hoisted into the frame and placed on both sides of the blind plate. After the shaft is passed through the through hole of the frame and the first shaft hole 4 of the clamp from the side, it is fixed by releasing the pin shaft of the positioning pin assembly and passing it through the positioning hole on the shaft.
[0026] like Figure 6-7 As shown, the two sets of shaft fixing blocks at the top are provided with U-shaped pull heads 12, and the installed components are lifted by passing the lifting rope through the U-shaped pull heads. After moving the entire component to align with the wheel hub 19, the bolt 13 is inserted into the second shaft hole 14 of the clamp 20, and the two ends are pre-tightened by the ball nuts 15 so that the clamp is combined and fixed with the wheel hub and the blind plate. At this time, the locating pin assembly can be released in order from bottom to top, and the shaft previously inserted into the first shaft hole of the clamp can be pulled out, replaced with another set of bolts and ball nuts and pre-tightened. The locating pin assembly can be quickly installed and the sealing ring can be automatically calibrated. After the installation is completed, the tooling can be easily disassembled as a whole.
[0027] like Figure 8 As shown, a lifting cross bar 16 is welded to the top of the positioning rod. Loosen the hexagon socket screws in the fixing holes on the limit block and take out the upper and lower positioning rods. Pull out the positioning rod by holding the lifting cross bar welded on the top of the positioning rod, and use a torque wrench to tighten the four sets of ball nuts by locking them on opposite sides. Loosen the hexagon socket screws on the back of the blind plate and remove the frame to complete the installation of the entire clamp flange.
[0028] The beneficial effects of the present invention are as follows: the clamp flange quick connector of the present invention can safely and quickly assemble and disassemble the connection between the blind plate and the wheel hub, and can also safely and accurately position the sealing ring during the assembly process, thereby improving the reliability of the installation, reducing the labor cost required for the installation, and bringing great convenience to production use.
[0029] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
