Description

Technical Field

[0001] This invention belongs to the field of automotive air conditioning, and specifically relates to the automated riveting of connecting pipes on the side outlet platform of the evaporator. Background Technology

[0002] Currently, there are two methods for installing the connecting pipes on the side outlet platform of evaporator products: the first is direct installation with clearance fit; the second is interference fit installation using tooling to tap it in. However, both methods have certain drawbacks. The first method is prone to causing the connecting pipes to come off or even fall off during the product loading process, while the second method also carries the risk of not tapping it in place or missing parts. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic cup mouth riveting device that rivets the connecting pipe and the manifold together by means of riveting, thereby automating the installation of the connecting pipe.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

[0005] An automatic cup rim riveting device includes a device bracket, a cylinder, and a gear and rack mechanism. The device bracket includes two guide shafts and four fixed plates. Two guide shafts are movably connected to two horizontal fixed plates (fixed plate one and fixed plate three), while the other two fixed plates are fixedly connected to the guide shafts. One end of the cylinder is fixed to fixed plate one with bolts, and the other end is fixed to fixed plate two with bolts. Cylinder two is fixedly connected to the back of fixed plate two with bolts, and the end of cylinder two is fixed to a connecting plate with bolts. The connecting plate is fixedly connected to fixed plate three with bolts, and two rivet heads are fixed to the connecting plate via the gear and rack mechanism.

[0006] Two fixed plates are movably connected to two guide shafts, which can move up and down; the other two fixed plates are fixedly connected to the guide shafts and move up and down with the guide shafts; the movable connection is made of linear bearings, and the fixed connection is made of bolts.

[0007] Two movable fixed plates are staggered with two fixed fixed plates.

[0008] The positive effects of this invention are as follows: This device can automatically rivet the inlet and outlet pipes. The external riveting of the inlet and outlet pipes is achieved by cylinder one, and the internal riveting of the inlet and outlet pipes is achieved by cylinder two driving two riveting joints. Through the internal and external riveting structure, the stability of the product and the working efficiency are improved. Attached Figure Description

[0009] Figure 1 This is a schematic diagram of the structure of the present invention;

[0010] Figure 2 Diagram showing the working state of the rivet joint as it rises;

[0011] Figure 3 Diagram showing the rivet joint in its lowering working state. Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] See Figure 1-3 The first end of cylinder 1 is bolted to the first fixed plate 8, and the last end of cylinder 1 is bolted to the second fixed plate 10. Cylinder 2 is bolted to the back of the second fixed plate 10, and the last end of cylinder 2 is bolted to the connecting plate 12. The connecting plate 12 and the third fixed plate 11 are bolted together. The first fixed plate 8 and the third fixed plate 11 are movably connected to the two guide shafts using linear bearings 9. The second fixed plate 10 and the fourth fixed plate 13 are fixedly connected to the two guide shafts using bolts or other methods. Furthermore, the two movably connected fixed plates and the two fixedly connected fixed plates are staggered.

[0014] Four fixed plates and two guide shafts form the device support. Two rivet joints are fixed to the connecting plate 12 by two gear and rack mechanisms.

[0015] When cylinder 1 rises and falls, it drives guide shaft 14, guide shaft 2 15, fixed plate 2 10 and fixed plate 4 13 to rise and fall together.

[0016] When cylinder 2 rises and falls, it causes the fixed plate 3 11, the connecting plate 12, the two gear and rack mechanisms 3, the rivet joint 1 5, and the rivet joint 2 6 to rise and fall together.

[0017] In operation, the connecting pipe 4 is first inserted into the D-shaped pipe 7 and placed below the device. Cylinder 1 presses down, causing the fixing plate 4 13 to descend, applying pressure to the upper part of the connecting pipe 4, ensuring a tight fit between the connecting pipe 4 and the outer joint of the D-shaped pipe 7. Simultaneously, riveting joint 5 and riveting joint 6 are inserted into the connecting pipe 4. The gear and rack mechanism 3 rotates the two riveting joints 90 degrees, and cylinder 2 lifts them upwards, causing the two riveting joints to rise. Under the pressure of the riveting joints, a riveting structure is formed between the connecting pipe 4 and the D-shaped pipe 7.

[0018] After riveting is completed, the gear and rack mechanism 3 rotates the two riveting joints, and the cylinder drives the device to lift the whole thing, removing the workpiece. The riveting process is now complete.
