Technical Field
[0001] This invention relates to the technical field of automotive component processing, and specifically to a fuel line expansion processing apparatus. Background Technology
[0002] The fuel line is a component of a car. During manufacturing, the end of the fuel line needs to be flared to facilitate the insertion of external accessories. The fuel line is then connected to the external accessories using a flexible fuel line clamp. However, because the original diameter of the fuel line clamp is smaller than that of the fuel line, it is inconvenient to fit the clamp onto the unflared or flared fuel line, making the whole process quite time-consuming. Summary of the Invention
[0003] The purpose of this invention is to provide a fuel pipe expansion processing apparatus to overcome the above-mentioned defects in the prior art.
[0004] A fuel pipe expansion processing device includes a worktable, a clamping mechanism, and an expansion sleeve clamping mechanism. The worktable is provided with a support base, and a fixing clamp is provided on one side of the support base. The clamping mechanism is located on the other side of the support base and is used to fix and clamp the fuel pipe. The expansion sleeve clamping mechanism is located on the worktable and behind the fixing clamp, and is used to flare the end of the fuel pipe and simultaneously clamp the fuel pipe onto the fuel pipe.
[0005] Preferably, the clamping mechanism includes a first cylinder and a movable clamping block. The first cylinder is mounted on a cylinder mounting plate on the workbench, and the bottom of the movable clamping block is slidably connected to a slide rail on the workbench, and its side is connected to the piston rod of the first cylinder.
[0006] Preferably, both the fixed clamping block and the movable clamping block have V-shaped grooves on their opposite sides.
[0007] Preferably, the tube expansion clamping mechanism includes a second cylinder, a flaring plate, and a pusher plate. The second cylinder is mounted on a cylinder mounting plate two on the workbench. The piston rod of the second cylinder passes through a fixed plate on the front side of the cylinder mounting plate two, and its end is provided with a truncated cone. Several flaring plates are provided and evenly distributed along the circumference of the fixed plate. The inner end of the flaring plate is slidably connected to a guide rod in a mounting groove on the fixed plate. A spring is sleeved on the guide rod. The inner end of the flaring plate is provided with a pressing block. The pressing block is provided with a pressing inclined surface that cooperates with the side of the truncated cone. A translation frame is provided on the inner side of one of the flaring plates. One end of the translation frame is slidably connected to the flaring plate, and the other end is connected to the truncated cone. The pusher plate is slidably inserted into the top of the translation frame and extends out through a through hole in the flaring plate.
[0008] Preferably, the front side of the flared plate is provided with an inclined surface for inserting holes, and the rear side of the flared plate is provided with a stepped section.
[0009] Preferably, the push plate has baffles symmetrically arranged on both sides of the through hole on the flared plate.
[0010] Preferably, the translation frame has an "L" shaped structure and connecting ears on both sides, which are slidably connected to the slide rails on the flared plate.

[0021] The following detailed description of the embodiments, with reference to the accompanying drawings, will further illustrate the specific implementation of the present invention, in order to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the concept and technical solutions of the present invention.
[0022] like Figure 1-7 As shown, the present invention provides a fuel pipe expansion processing device, including a worktable 1, a clamping mechanism 4, and an expansion sleeve clamping mechanism 5. The worktable 1 is provided with a support base 2, and a fixing clamp 3 is provided on one side of the support base 2. The clamping mechanism 4 is provided on the other side of the support base 2 and is used to fix and clamp the fuel pipe 6. The expansion sleeve clamping mechanism 5 is provided on the worktable 1 and is located behind the fixing clamp 3. It is used to widen the end of the fuel pipe 6 and simultaneously sleeve the fuel pipe clamp 61 on the fuel pipe 6.
[0023] It should be noted that the clamping mechanism 4 includes a first cylinder 41 and a movable clamping block 43. The first cylinder 41 is mounted on a cylinder mounting plate 42 on the workbench 1. The bottom of the movable clamping block 43 is slidably connected to a slide rail 44 on the workbench 1 and its side is connected to the piston rod of the first cylinder 41. The fixed clamping block 3 and the movable clamping block 43 are both provided with V-grooves 31 on opposite sides.
[0024] It is worth noting that the tube expansion and clamping mechanism 5 includes a second cylinder 51, a flaring plate 53, and a pusher plate 58. The second cylinder 51 is mounted on a cylinder mounting plate 511 on the workbench 1. The piston rod of the second cylinder 51 passes through a fixed plate 54 on the front side of the cylinder mounting plate 511, and its end is provided with a truncated cone 52. Several flaring plates 53 are provided and evenly distributed along the circumference of the fixed plate 54. The front side of the flaring plate 53 is provided with an insertion inclined surface 531, and the rear side of the flaring plate 53 is provided with a stepped section 532. The inner end of the plate 53 is slidably connected to the guide rod 55 in the mounting groove 541 on the fixed plate 54. A spring 551 is sleeved on the guide rod 55. The inner end of the flared plate 53 is provided with an extrusion block 56. The extrusion block 56 is provided with an extrusion inclined surface 561 that cooperates with the side of the truncated cone 52. A translation frame 57 is provided on the inner side of one of the flared plates 53. One end of the translation frame 57 is slidably connected to the flared plate 53, and the other end is connected to the truncated cone 52. The push plate 58 is slidably inserted into the top of the translation frame 57 and extends out through the through hole on the flared plate 53.
[0025] In addition, the push plate 58 is provided with baffles 581 symmetrically on both sides of the through hole on the flared plate 53. The baffles 581 on both sides of the push plate 58 prevent the push plate 58 from falling during its upward movement.
[0026] In addition, the translation frame 57 has an "L" shaped structure and connecting ears 571 are provided on both sides. The connecting ears 571 are slidably connected to the slide rails 572 on the flared plate 53, so that the translation frame 57 can move more smoothly.
[0027] Detailed implementation methods and principles:
[0028] In practical application, the present invention first places the fuel line clamp 61 to be used on the high point of the stepped section 532 of the flared plate 53, and places it on the same horizontal plane as the baffle 581 of the push plate 58. Then, the fuel line 6 is placed on the support base 2 and moved so that its end is inserted into the flared plate 53, and the end of the fuel line 6 is located at the low point of the stepped section 532. Next, the piston rod of the first cylinder 41 on the cylinder mounting plate 1 is extended to drive the moving clamp 43 to move along the slide rail 44 on the worktable 1, fixing the fuel line 6 between the moving clamp 43 and the fixed clamp 3. Then, the piston rod of the second cylinder 51 on the cylinder mounting plate 2 is extended to drive the truncated cone 52 to move forward, and the side of the truncated cone 52 drives the fuel line 6 to move forward. The extrusion block 56 and the flaring plate 53 move in all directions to flare the end of the fuel pipe 6. At the same time, the fuel pipe clamp 61 on the flaring plate 53 is opened. The translation frame 57 moves along the bottom of the flaring plate 53 and drives the push plate 58 to move and push the fuel pipe clamp 61 onto the fuel pipe 6. After the fuel pipe 6 is flared and the fuel pipe clamp 61 is fitted onto the fuel pipe 6, the piston rod of the second cylinder 51 is controlled to retract, driving the cone 52 to reset. Then, under the action of the spring 551 on the guide rod 55, the flaring plate 53 is reset. Then, the piston rod of the first cylinder 41 is controlled to retract, driving the moving clamp 43 to reset along the slide rail 44 on the worktable 1 to release the fuel pipe 6. Then, the processed fuel pipe 6 is removed from the worktable 1.
[0029] In summary, the present invention clamps and fixes the fuel pipe 6 by means of the clamping mechanism 4, and then widens the fuel pipe 6 by means of the widening plate 53 of the pipe expansion clamping mechanism 5. At the same time as widening, the fuel pipe clamp 61 is pushed onto the fuel pipe 6 by means of the push plate 58 on the translation frame 57, which avoids the cumbersome operation of putting the fuel pipe clamp 61 onto the fuel pipe 6 and saves processing efficiency of the fuel pipe 6.
[0030] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the concept and technical solution of the present invention, or the direct application of the present invention and technical solution to other situations without modification, are all within the protection scope of the present invention.
