[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as commonly understood by those of ordinary skill in the art to which the present invention belongs.

[0031] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention.

[0032] Example 1

[0033] like Figure 1 As shown, this embodiment discloses a crimping tool for bamboo-jointed pipe fittings of a passenger car fuel pipeline, comprising a base 1, with a pushing device and a clamping device fixedly provided at both ends of the base 1;

[0034] The pushing device includes a push rod 5 and a pressure head 6 that are fixedly connected. The surface of the pressure head 6 is provided with grooves of various sizes, which are used to fix the bamboo tube fittings; the clamping device includes a tube clamp 8, which includes a symmetrical upper pressing plate 8-3 and a lower pressing plate 8-4. The inner sides of the two pressing plates are respectively provided with circular arc grooves of various sizes and symmetrical to each other. After clamping the two pressing plates, through holes of various sizes are formed, which are used to fix the nylon tube; the fixed nylon tube corresponds to the bamboo tube fitting.

[0035] The pushing device also includes a support frame 2, a handle 3 and a connecting rod 4; the left end of the support frame 2 and the handle 3, the handle 3 and the connecting rod 4, and the connecting rod 4 and the left end of the push rod 5 are all connected by hinge rotation. This connection method is firm and reliable, and saves more effort when crimping the tooling.

[0036] The right end of the support frame 2 is provided with a cylindrical hole, through which the right end of the push rod 5 passes. The push rod 5 and the cylindrical hole are clearance-fitted, allowing for left and right sliding within the support frame 2. The push rod 5 can slide left and right within the support frame 2, thereby achieving left and right movement of the ram 6. The right end of the push rod 5 has an internally threaded hole, and the left end of the ram 6 has an external thread. The ram 6 and push rod 5 are connected by internal and external threads, allowing for rotation between the ram 6 and push rod 5.

[0037] like Figure 2 As shown, the surface of the pressing head 6 is provided with slots of various sizes around it and the pressing head 6 can be rotated to fix the bamboo tube fittings. By rotating the pressing head 6 to select the slots that match the size of the bamboo tube fittings, the bamboo tube fittings of different sizes can be crimped.

[0038] like Figure 3 As shown, the pipe clamp 8 also includes bolts 8-1 and nuts 8-2 on both sides; the bolt 8-1 passes through the two ends of the upper and lower clamping plates after clamping, and the two ends of the upper clamping plate 8-3 are clearance-matched with the bolt 8-1, and the two ends of the lower clamping plate 8-4 are provided with threaded holes, which are engaged with the bolt 8-1. By tightening the bolts 8-1 on both sides of the pipe clamp 8, the pipe clamp 8 can clamp the nylon tube without damaging the nylon tube. After clamping the two clamping plates, through holes of various sizes are formed. By selecting appropriate through holes to fix the nylon tube, the crimping of nylon tubes of different diameters can be achieved.

[0039] like Figure 4(a) 、 4(b) As shown, the clamping device also includes a pipe clamp support block 7, which includes a transverse groove and a longitudinal groove. A pipe clamp 8 is placed in the transverse groove of the pipe clamp support block 7 and moves left and right within the pipe clamp support block 7. The nylon tube is placed in the longitudinal groove of the pipe clamp support block 7. The left and right movement of the pipe clamp 8 within the pipe clamp support block 7 can improve the alignment of the bamboo tube fitting and the nylon tube during crimping. After being fixed, the nylon tube and the bamboo tube fitting correspond to each other and their center lines are aligned.

[0040] In this embodiment, the base 1 is a steel plate, and the support frame 2 and the pipe clamp support block 7 require four and two hexagon socket bolts 9 to be fixed to the two ends of the base 1 respectively.

[0041] In this embodiment, the detailed crimping process of the passenger car fuel line bamboo tube crimping tool is as follows:

[0042] When in use, the pressing head 6 is rotated according to the size of the bamboo tube, and a suitable slot on the pressing head 6 is selected. When the required slot is located at the top, the bamboo tube is placed into the slot and fixed.

[0043] Select the appropriate through hole of the pipe clamp 8 according to the diameter of the nylon tube, tighten the bolts 8-1 on both sides of the pipe clamp to clamp the nylon tube with the upper clamping plate 8-3 and the lower clamping plate 8-4, place the tightened pipe clamp 8 in the horizontal groove of the pipe clamp support block 7, and place the nylon tube in the longitudinal groove of the pipe clamp support block 7.

[0044] Pressing the handle 3 causes the hinge to rotate, and the connecting rod 4 drives the push rod 5 to move toward the nylon tube. The push rod 5 slides left and right in the cylindrical hole at the right end of the support frame 2, thereby realizing the left and right movement of the pressure head 6. After the nylon tube and the bamboo tube are aligned with each other and the center lines are adjusted to be in a straight line, the handle 3 is continued to be pressed to drive the pressure head 6, and the bamboo tube is pressed into the nylon tube by the pressure head 6.

[0045] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
