[0002] The fuel distribution pipe is a part of the automobile engine. Its sealing is an important factor in automobile safety. The copper ring press-fitting process of the bracket block is an important factor affecting the firm installation of the fuel distribution pipe.

[0003] At present, the copper ring of the fuel distribution pipe is pressed and installed by transitionally fitting the copper ring and the distribution pipe. The premise is that the distribution pipe must be processed with a step hole. The purpose is to prevent the copper ring from falling off and falling into the inside of the distribution pipe after the copper ring is pressed. Because the copper rings are of different sizes, the states of the copper rings after pressing are different. If there is a back and forth bump, the copper ring will fall off and fall into the inside of the distribution pipe, which will affect the quality of the product. Summary of the invention

DETAILED DESCRIPTION

[0023] The invention discloses a distribution pipe copper ring expansion installation fixture, comprising a mounting platform and a distribution pipe clamping component arranged on the mounting platform, such as Figure 1 , Figure 2 As shown, the mounting platform is provided with a fixing plate 1 with a through hole, a guide block 2 with a through hole is fixedly arranged at the through hole of the fixing plate 1, a copper ring expansion sleeve 3 is inserted into the through hole of the guide block 2, a conical pressure rod 4 is connected to a connecting rod 5 through the copper ring expansion sleeve 3 and the through holes of the fixing plate 1 and the guide block 2, and the connecting rod 5 is connected to a cylinder 6 under the fixing plate 1.

[0024] like Figure 3 As shown, the copper ring expansion sleeve 3 is made of a metal round tube, which is processed into several claw-shaped parts 31 separated from the upper part at the bottom, and a step surface is set at the same height on the upper end of each claw-shaped part 31, and each step surface constitutes a copper ring positioning surface 32. The setting of the claw-shaped part 31 allows the copper ring expansion sleeve 3 to passively expand during the insertion of the conical pressure rod 4, and can return to its original position after the conical pressure rod 4 rises and detaches from the copper ring expansion sleeve 3. The copper ring 12 is placed on the copper ring positioning surface 32 and is stretched open as the copper ring expansion sleeve 3 expands. In order to ensure that when the inverted conical pressure rod 4 enters the expansion, there is a large enough contact area to ensure stable force, the expansion formed by the inner walls of all claw-shaped parts 31 is an inner conical arc surface that cooperates with the conical pressure rod 4, that is, the diameter of the inner conical arc surface near the head is larger than the diameter near the bottom. At the bottom of the copper ring expansion sleeve 3, a connection hole for connecting other components is arranged.

[0025] The cylinder 6 drives the connecting rod 5, and drives the pressure rod 4 to be lifted and lowered to be inserted into or away from the copper ring expansion sleeve 3. Because the pressure rod 4 is conical, the cone head part faces the copper ring expansion sleeve 3. When the pressure rod 4 is inserted into the copper ring expansion sleeve 3, as the pressure rod 4 is gradually inserted into the copper ring expansion sleeve 3, the claw-shaped component 31 of the copper ring expansion sleeve 3 gradually expands, driving the copper ring 12 to expand and deform. After a period of time, the pressure rod 4 rises and escapes from the copper ring expansion sleeve 3, and the claw-shaped component 31 of the copper ring expansion sleeve 3 returns to its original position. The copper ring 12 cannot be restored due to the deformation caused by the force.

[0026] The distribution pipe clamping component includes a vertical plate 7 fixedly mounted on the mounting platform, and a distribution pipe positioning block 8 and a quick clamp 9 arranged on the vertical plate. The vertical plate 7 is mounted on the copper ring mounting platform in an inlaid manner; preferably, Figure 1As shown, two distribution pipe positioning blocks 8 and two quick clamps 9 are provided, so that the distribution pipe 11 can be positioned accurately and firmly.

[0027] like Figure 4 As shown, according to different product requirements, the technical requirements for the depth of the copper ring 12 installed in the distribution pipe 11 are different. In this regard, this requirement can be met by installing an adjustment block 10 with a through hole on the upper part of the guide block 2. The adjustment block 10 has a variety of different models to meet the technical requirements of different products. The copper ring expansion sleeve 3 passes through the through hole of the adjustment block 10 and is inserted into the through hole of the guide block 2.

[0028] The method for installing a copper ring on a distribution pipe using the above distribution pipe copper ring expansion installation fixture comprises the following steps:

[0031] In the third step, the cylinder 6 is ventilated to drive the pressure rod 4 to descend, expand the copper ring expansion sleeve 3, and cause the copper ring 12 to deform due to the expansion of the copper ring expansion sleeve 3, so that the copper ring 12 is expanded and fits tightly with the distribution pipe 11;

[0032] In the fourth step, the cylinder 6 is ventilated to drive the pressure rod 4 to rise, the copper ring expansion sleeve 3 returns to its position, the quick clamp 9 is released, the distribution pipe 11 is taken out, another copper ring 12 is placed on the copper ring expansion sleeve positioning surface 32, the copper ring 12 is positioned, and the other end of the distribution pipe 11 is re-placed on the distribution pipe positioning block 8, so that the lower end surface of the distribution pipe 11 is in contact with the upper end surface of the guide block 2, the copper ring 12 is inserted into the distribution pipe 11, and the quick clamp 9 is started to press the distribution pipe 11;

[0033] In the fifth step, the cylinder 6 is ventilated to drive the pressure rod 4 to descend, expand the copper ring expansion sleeve 3, and cause the copper ring 12 to deform due to the expansion of the copper ring expansion sleeve 3, so that the copper ring 12 is expanded and fits tightly with the distribution pipe 11;

[0034] In the sixth step, the cylinder 6 is ventilated to drive the pressure rod 4 to rise, the copper ring expansion sleeve 3 returns to its original position, the quick clamp 9 is released, and the distribution pipe 11 is taken out.

[0035] In the second and fourth steps, an adjustment block 10 with a through hole is installed on the upper part of the guide block 2 to adjust the depth of the copper ring 12 installed in the distribution pipe 11. The copper ring expansion sleeve 3 passes through the through hole of the adjustment block 10 and is inserted into the through hole of the guide block 2. The lower end surface of the distribution pipe 11 fits with the upper end surface of the adjustment block 10.
