Description

Technical Field

[0001] The utility model relates to the technical field of automobile air-conditioning pipeline tooling, in particular to an assembly tooling for an automobile air-conditioning pipeline clamp. Background Art

[0002] Automobile air-conditioning pipelines are mainly used to transport the refrigerant medium of the air-conditioning system, so that the refrigerant can circulate between the compressor, the evaporator and the condenser, thereby ensuring that the evaporator can transfer the cold quantity to the interior of the automobile in a heat exchange manner, and enabling the temperature inside the vehicle to be well regulated. During the installation process of the automobile air-conditioning pipeline, it is necessary to first press-fit the clamp on the air-conditioning pipeline, and then fix and install it on the vehicle body through the clamp. This is mainly to avoid the displacement or loosening of the air-conditioning pipeline caused by the vibration generated during the driving of the automobile, and thus ensure the service life of the air-conditioning pipeline.

[0003] In the prior art, the clamp is mostly automatically tooled by using hydraulic equipment and special molds. Not only is the processing efficiency high, but also the consistency of the product is ensured. However, the cost of a set of special tooling equipment for automobile air-conditioning pipeline clamps is about 50,000 to 60,000 yuan, and the cost required for mass production is too high. Therefore, some automobile manufacturers mostly use manual tooling. The operator uses tools such as a vise to fix and install the clamp on the air-conditioning pipeline. However, the thickness of the clamp used in this method cannot be too thick. Once the thickness of the clamp is too thick, not only the assembly efficiency is reduced, but also the surface of the clamp is damaged due to excessive force by the employee, which affects the yield rate of the product. Summary of the Utility Model

[0030] The following further describes the present utility model in conjunction with the embodiments and the drawings.

[0031] The assembly tooling for automotive air-conditioning pipeline clamps provided in this embodiment is used for assembling Figure 8 and Figure 9The shown pipe clamp 21, wherein, the pipe clamp 21 includes a pipe clamp base body 21a. A tooling section 21b is vertically folded downward at the front end of the pipe clamp base body 21a. A tooling hole 21b1 is formed on the tooling section 21b, and a bolt is used to pass through the tooling hole 21b1 so that the air-conditioning pipeline 22 is fixedly installed on the vehicle. The rear end of the pipe clamp base body 21a is bent upward to form an arc section 21c. An arch structure 21d is formed at the end of the arc section 21c. One end of the arch structure 21d away from the arc section 21c extends forward to form a pressing section 21e. By applying a downward force to the pressing section 21e, the pressing section 21e can be made to fit on the upper surface of the pipe clamp base body 21a. At this time, the arc section 21c and the arch structure 21d can form a closed circle, thereby covering the air-conditioning pipeline 22. On the left and right sides of the pipe clamp base body 21a, rack teeth 21f are vertically formed upward. By applying a force to the outer surface of the rack teeth 21f, the rack teeth 21f can be folded inward, thereby locking the pressing section 21e on the upper surface of the pipe clamp base body 21a.

[0032] As Figure 1 and Figure 2 shown, an assembly tooling for an automotive air-conditioning pipeline pipe clamp includes a tooling table 1. The top of the tooling table 1 is used to place the pipe clamp 21 to be assembled. Support columns 2 are fixedly installed at both the left and right ends of the tooling table 1 through bolts. Positioning grooves 2a are formed at the tops of the support columns 2. In this embodiment, the positioning grooves 2a are used to position and clamp the air-conditioning pipeline 22 to be assembled to ensure that the air-conditioning pipeline 22 does not move when tooling the pipe clamp 21, thereby ensuring the tooling quality. A pipe clamp positioning component A is installed at the rear end of the tooling table 1. The pipe clamp positioning component A is used to apply a force to the pressing section 21e of the pipe clamp 21 so that the pressing section 21e fits on the upper surface of the pipe clamp base body 21a, thereby ensuring that the pipe clamp 21 is sleeved on the air-conditioning pipeline 22. A rack pressing-down component B is installed at the front end of the tooling table 1. The rack pressing-down component B is mainly used to apply a force to the outer surface of the rack teeth 21f so that the rack teeth 21f are folded inward, locking the pressing section 21e on the upper surface of the pipe clamp base body 21a, thereby ensuring that the pipe clamp 21 sleeved on the air-conditioning pipeline 22 can be locked and will not easily loosen and slide off.

[0033] Designed in this way, through the pipe clamp positioning component A and the rack pressing-down component B, the mechanized tooling of the pipe clamp 21 is realized. Compared with manual tooling, the tooling efficiency is greatly improved, and at the same time, the product consistency is ensured.

[0034] As Figure 1As shown in the figure, the pipe clip assembly tooling for automotive air-conditioning pipelines further includes a fixed bottom plate 3 and an installation platform 4. The pipe clip positioning assembly A and the rack pressing-down assembly B are both fixedly installed on the fixed bottom plate 3 by bolts. The tooling table 1 and the support column 2 are fixedly installed on the top of the installation platform 4 by bolts. The installation platform 4 is supported on the fixed bottom plate 3 by six support guide rods 5, so as to ensure that the structure of this pipe clip assembly tooling for automotive air-conditioning pipelines is more compact and stable.

[0035] As Figure 4 shown in the figure, the pipe clip positioning assembly A includes a first lifting cylinder 6, a first connecting block 7 and a pipe clip positioning press head 8. The first lifting cylinder 6 is vertically installed on the fixed bottom plate 3 by bolts. The first connecting block 7 is fixedly installed at the end of the cylinder rod of the first lifting cylinder 6 by bolts. One end of the pipe clip positioning press head 8 is rotatably installed on the first connecting block 7, and the other end is rotatably installed at the rear end of the tooling table 1. Through the lifting movement of the first lifting cylinder 6, the pipe clip positioning press head 8 can rotate in the vertical plane with the end close to the tooling table 1 as the rotation point, and then apply a downward force to the pressing section 21e.

[0036] In this embodiment, an arc structure 8a is formed at the end of the pipe clip positioning press head 8 close to the tooling table 1. The radian of the inner diameter of the arc structure 8a is adapted to the radian of the arched structure 21d, and the end of the arc structure 8a can directly apply a force to the pressing section 21e. With such a design, through the design of the arc structure 8a, the surface of the pipe clip 21 can be effectively prevented from being worn during tooling, thereby ensuring the yield rate of the tooling.

[0037] Furthermore, as Figure 5 shown in the figure, the first connecting block 7 is a "U"-shaped block. A first guide rod 7a is inserted through the top of the first connecting block 7. A first sleeve 7b is sleeved in the middle of the first guide rod 7a. A first strip-shaped hole 8b is formed at one end of the pipe clip positioning press head 8 close to the first connecting block 7 along the length direction of the pipe clip positioning press head 8. The width dimension of the first strip-shaped hole 8b is the same as the outer diameter dimension of the first sleeve 7b. The length dimension of the first sleeve 7b is consistent with the depth dimension of the first strip-shaped hole 8b. Second sleeves 7c are also sleeved at the left and right ends of the first guide rod 7a. The outer diameter dimension of the second sleeves 7c is larger than the outer diameter dimension of the first sleeve 7b, so as to ensure that the pipe clip positioning press head 8 will not sway left and right when the first lifting cylinder 6 drives the pipe clip positioning press head 8 to rotate.

[0038] As Figure 6As shown in the figure, the rack pressing-down assembly B includes a second lifting cylinder 9, a second connecting block 10, a rotating arm 11, a transmission rod 12, a rack pressing-down head 13 and a positioning plate 14. Among them, the positioning plate 14 is fixedly installed at the front end of the tooling table 1 by bolts. There are two symmetrically arranged positioning holes 14a on the positioning plate 14. The transmission rod 12 is passed through each positioning hole 14a. The rack pressing-down head 13 is fixedly installed at one end of the transmission rod 12 close to the tooling table 1. In this embodiment, both rack pressing-down heads 13 extend an extension part 13a towards each other. By rotating the transmission rod 12, the extension part 13a can apply a force to fold the rack 21f inward. The other side of the transmission rod 12 is fixedly connected to the rotating arm 11, and the transmission rod 12 and the rotating arm 11 are perpendicular to each other in space. The second lifting cylinders 9 are installed on both the left and right sides at the front end of the positioning plate 14. The second lifting cylinders 9 are vertically installed on the fixed bottom plate 3 by bolts. The second connecting block 10 is fixedly installed at the end of the cylinder rod of the second lifting cylinder 9 by bolts. One end of the rotating arm 11 far from the transmission rod 12 is rotatably installed on the top of the second connecting block 10. Through the lifting action of the second lifting cylinder 9, the rotating arm 11 can rotate in the vertical direction, thereby driving the rack pressing-down head 13 to rotate, and finally enabling the rack 21f to flip inward and lock the pressing section 21e on the upper surface of the pipe clamp base 21a.

[0039] Further, as Figure 7 shown, the second connecting block 10 is also a "U"-shaped block. A second guide rod 10a is passed through the top of the second connecting block 10. A third sleeve 10b is sleeved in the middle of the second guide rod 10a. One end of the rotating arm 11 close to the second connecting block 10 is formed with a second strip-shaped hole 11a along the length direction of the rotating arm 11. The width dimension of the second strip-shaped hole 11a is the same as the outer diameter dimension of the third sleeve 10b. The length dimension of the third sleeve 10b is consistent with the depth dimension of the second strip-shaped hole 11a. The left and right ends of the second guide rod 10a are also sleeved with fourth sleeves 10c. The outer diameter dimension of the fourth sleeve 10c is larger than the outer diameter dimension of the third sleeve 10b. In this way, when the second lifting cylinder 9 drives the rotating arm 11 to rotate, the rotating arm 11 will not sway left and right.

[0040] Again, as Figure 7 shown, a limiting hole 14b is formed in the middle of the positioning plate 14. A limiting rod 15 is passed through the limiting hole 14b. A limiting protrusion 15a is installed on the side of the limiting rod 15 close to the tooling table 1. The limiting rod 15 can be adjusted back and forth relative to the positioning plate 14 so that the tooling section 21b of the pipe clamp 21 is clamped between the tooling table 1 and the limiting protrusion 15a, thereby ensuring that the pipe clamp 21 can be stably placed on the tooling table 1 and will not sway during tooling.

[0041] As Figure 1As shown in the figure, a first manual valve 16 and a second manual valve 17 are also fixedly installed on the fixed base plate 3. The air pipe of the first lifting cylinder 6 is connected to the first manual valve 16, and the air pipe of the second lifting cylinder 9 is connected to the second manual valve 17. With such a design, the lifting of the first lifting cylinder 6 can be controlled through the first manual valve 16, and the lifting of the second lifting cylinder 9 can be controlled through the second manual valve 17, which is very convenient to operate and thus conducive to accelerating the tooling efficiency.

[0042] As Figure 1 and Figure 3 shown in the figure, an installation column 18 is also installed on the right side of the installation platform 4. A limit block 19 is fixedly installed at the top of the installation column 18, and a limit groove 19a is formed on the side of the limit block 19. The limit groove 19a is also used for clamping the air-conditioning pipeline 22. With such a design, the entire assembly tooling device for the automotive air-conditioning pipeline clamp can be adapted to the tooling of the air-conditioning pipeline 22 of a right-hand drive vehicle, improving the utilization rate of the entire assembly tooling for the automotive air-conditioning pipeline clamp.

[0043] As Figure 1 shown in the figure, handles 20 are symmetrically installed at the left and right ends of the top of the fixed base plate 3. Through the handles 20, it is convenient to transfer the position of the entire assembly tooling device for the automotive air-conditioning pipeline clamp.

[0044] As Figure 4 shown in the figure, a stepped structure 1a is provided at the rear end of the top of the tooling table 1. When the pipe clamp 21 is placed on the top of the tooling table 1, the arched structure 21d can abut against the stepped structure 1a to ensure the stable placement of the pipe clamp 21. A boss 1b also extends forward at the front end of the tooling table 1. When tooling is carried out, the boss 1b can penetrate into the tooling hole 21b1, further ensuring the stable placement of the pipe clamp 21 on the top of the tooling table 1.

[0045] In this embodiment, when the pipe clamp 21 is tooled onto the air-conditioning pipeline 22, a rubber pad 23 also needs to be installed between the pipe clamp 21 and the air-conditioning pipeline 22. Through the provided rubber pad 23, a flexible buffer can be formed between the pipe clamp 21 and the air-conditioning pipeline 22, thereby avoiding damage to the air-conditioning pipeline 22 caused by friction between the pipe clamp 21 and the air-conditioning pipeline 22.

[0046] Combining the above structures, the working principle of the assembly tooling for the automotive air-conditioning pipeline clamp is as follows:

[0047] First, place the pipe clamp 21 on the surface of the tooling table 1, ensuring that the boss 1b is clamped in the tooling hole 21b1, and the arched structure 21d abuts against the stepped structure 1a. Adjust the limit rod 15 so that the tooling section 21b is clamped between the tooling table 1 and the limit projection 15a. Wrap the rubber pad 23 around the required tooling section of the air-conditioning pipeline 22, and then respectively clamp the left and right ends of the air-conditioning pipeline 22 in the positioning grooves 2a. Drive the first hand valve 16 to lift the first lifting cylinder 6. While the first lifting cylinder 6 is lifting, drive the pipe clamp positioning press head 8 to rotate with the tooling table 1 as the rotation point. The arc structure 8a applies a force to the pressing section 21e so that the pressing section 21e fits on the upper surface of the pipe clamp base 21a. At this time, the arc section 21c and the arched structure 21d form a closed circle, thereby wrapping the air-conditioning pipeline 22 and the rubber pad 23. The arc structure 8a effectively prevents the arc section 21c from being worn. Then drive the first hand valve 16 to lower the first lifting cylinder 6, and then drive the second hand valve 17 to lift the second lifting cylinder 9. While the second lifting cylinder 9 is lifting, drive the rotating arm 11 to rotate in the vertical direction, and then drive the rack pressing head 13 to rotate towards the direction where the rack 21f is located. The extension 13a applies a force to the rack 21f to fold it inward, so that the pressing section 21e is locked between the rack 21f and the pipe clamp base 21a. Finally, drive the second hand valve 17 to lower the second lifting cylinder 9, thereby completing the entire tooling of the pipe clamp 21.

[0048] With such a design, the tooling of the pipe clamp 21 is only completed by cylinder control. Compared with using a hydraulic system, the overall cost is very low. Compared with pure manual tooling, the tooling efficiency is higher, and at the same time, the consistency of the product can be guaranteed.

[0049] Finally, it should be noted that the above description is only the preferred embodiment of the present invention. Under the inspiration of the present invention, those of ordinary skill in the art can make various similar representations without departing from the purpose and claims of the present invention. Such transformations all fall within the protection scope of the present invention.
