Technical Field
[0001] The present disclosure belongs to the technical field of riveting equipment, and particularly relates to a device for riveting a water outlet pipe to an end cover of a high-voltage battery cooler. Background Art
[0002] A high-voltage battery cooler is a type of heat exchanger that combines the functions of an evaporator and a heat exchanger. It is a key component for coupling the battery liquid cooling circuit and the cockpit air conditioning circuit, and is also one of the incremental components of the new energy vehicle thermal management system under the liquid cooling solution;
[0003] In the manufacturing field of high-voltage battery cooler components, it is usually necessary to reliably rivet-connect the water outlet pipe to the cooler end cover to ensure the sealing and stability of the component; however, in the prior art during stamping riveting, a convex-shaped stamping part needs to be inserted into the water outlet pipe, and the inner circumferential wall of the riveting end of the water outlet pipe is extruded outward, causing the inner wall of the riveting end of the water outlet pipe to deform and extend away from its central axis end. However, since the lower end of the stamping part is convex-shaped, it is impossible to ensure sufficient fitting between the stamping-deformed part of the water outlet pipe and the cooler end cover. Such an adverse phenomenon may lead to problems such as poor sealing and increased leakage risk; therefore, there are problems of poor flatness of the riveting part and poor riveting stability in the prior art.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present disclosure.
[0032] Herein, in combination with Figures 1 to 5An embodiment of a device for riveting an outlet pipe to the end cover of a high-voltage battery cooler is described. Specifically, the device for riveting an outlet pipe to the end cover of a high-voltage battery cooler is configured as a split structure, which has components such as a riveting head assembly 400, a riveting head column 404, a driving part, a first telescopic cylinder 300, a support plate 500, a connecting plate 600, etc. Through the setting method that the lower end of the riveting head column 404 is in a spherical shape protruding downward and the upper end surface of the riveting head column 404 is in a horizontal plane shape, the driving part is used to drive the upper and lower end surfaces of the riveting head column 404 to flip. After using the spherical shape of the riveting head column 404 for riveting and stamping, the riveting head column 404 is flipped again, so that the flat end of the riveting column 404 squeezes the outlet pipe riveting component again, improving the flatness of the riveting part and at the same time improving the stability of the riveting.
[0033] Please refer to Figures 1 to 5 , a device for riveting an outlet pipe to the end cover of a high-voltage battery cooler, including a bottom plate 100, above which a riveting head assembly 400 is provided. The riveting head assembly 400 includes a vertically placed riveting head column 404 and a driving part. The lower end of the riveting head column 404 is in a spherical shape protruding downward, and the upper end surface of the riveting head column 404 is in a horizontal plane shape. The driving part is used to drive the upper and lower ends of the riveting head column 404 to flip;
[0034] A fixing frame 200 is fixed on the bottom plate 100. The upper end of the riveting head assembly 400 is connected to a first telescopic cylinder 300 for driving its lifting and moving. The first telescopic cylinder 300 is installed on the fixing frame 200;
[0035] A horizontally placed support plate 500 is provided below the riveting head assembly 400. A circular through-hole 501 located directly below the riveting head assembly 400 is opened on the support plate 500. The support plate 500 is fixed to the bottom plate 100 through a pair of connecting plates 600.
[0036] The riveting head column 404 is usually made of high-strength alloy steel material, and its surface may be processed by grinding, polishing, etc. to ensure its surface finish and accuracy, which can effectively improve the corrosion resistance and wear resistance of the riveting head 404.
[0037] The diameter of the first telescopic cylinder 300 usually determines the magnitude of its output force and the ability to withstand pressure. Common diameters are 25mm, 32mm, 40mm, etc. In this device, the cylinder pressure of the first telescopic cylinder 300 during riveting is 5 ± 0.5 Mpa, and the pressurization time is 4S.
[0038] The support plate 500 is generally made of steel or aluminum alloy with good mechanical strength to support and stabilize the end cover of the high-voltage battery cooler and be able to withstand the stamping pressure of the first telescopic cylinder 300; the surface of the support plate 500 can be subjected to anodic oxidation or electroplating treatment, etc.
[0039] During use, place the end cover of the high-voltage battery cooler on the support plate 500, and align the riveting holes on the end cover of the high-voltage battery cooler where the water outlet pipe is to be riveted with the circular through-hole 501 coaxially. The worker holds the water outlet pipe, and passes the riveting end of the water outlet pipe through the circular through-hole 501 and the riveting hole in sequence from below the support plate 500, so as to pre-assemble the water outlet pipe with the end cover of the high-voltage battery cooler; turn on the first telescopic cylinder 300 to push the riveting head assembly 400 downward, so that the spherical end of the riveting head column 404 presses and rivets the upper end of the water outlet pipe, causing the inner peripheral wall of the upper end of the water outlet pipe to extend and deform outward; then drive the riveting head assembly 400 to move slightly upward through the first telescopic cylinder 300, and drive the upper and lower ends of the riveting head column 404 to flip through the driving part, and finally drive the flat end of the riveting head column 404 to move downward again through the first telescopic cylinder 300 to press the upper end of the water outlet pipe again, making the riveting part of the water outlet pipe flat.
[0040] The driving part includes a mounting plate 401. The mounting plate 401 is fixed to the output end of the first telescopic cylinder 300. A vertically placed connecting shaft 402 is fixed to the lower end of the mounting plate 401. A mounting seat 403 is fixed to the lower end of the connecting shaft 402. A horizontally placed rotating shaft is rotatably connected to the mounting seat 403. One end of the rotating shaft is connected to a first rotating motor 405. The first rotating motor 405 is arranged on the mounting seat 403. The riveting head column 404 is fixedly sleeved on the rotating shaft; the rotating shaft can be driven by turning on the first rotating motor 405, and the rotating shaft drives the upper and lower end faces of the riveting head column 404 to flip.
[0041] The diameter of the riveting head column 404 is larger than the diameter of the circular through-hole 501; that is, this device can perform riveting operations on various specifications of water outlet pipes with a diameter less than or equal to the diameter of the circular through-hole 501.
[0042] In order to automatically clamp the water outlet pipe and reduce the safety hazards existing in manually holding the water outlet pipe during riveting, the two connecting plates 600 are respectively located on both sides of the central axis of the circular through-hole 501. Horizontally placed second telescopic cylinders 700 are fixed on the connecting plates 600. The output ends of the second telescopic cylinders 700 all face the central axis of the circular through-hole 501 and are fixed with clamping blocks 701. The second telescopic cylinders 700 are all located at one end of the side wall of the connecting plate 600 close to the support plate 500; the two clamping blocks 701 are pushed by the two second telescopic cylinders 700, and the water outlet pipe is clamped and fixed by the mutual approach of the two clamping blocks 701.
[0043] In order to facilitate clamping of water outlet pipes with various different diameters, the clamping block 701 is made of elastic rubber material; through the extrusion of the clamping block 701 and the water outlet pipe, the side of the clamping block 701 close to the water outlet pipe undergoes elastic deformation, automatically forming a groove that fits the peripheral wall of the water outlet pipe, facilitating clamping and fixing of water outlet pipes with various different diameters.
[0044] When stamping and riveting, the riveting head assembly 400 will apply a downward pressure on the water outlet pipe. To prevent the water outlet pipe from sliding downward under stamping during riveting, vertical sliding grooves are provided on one side of the connecting plate 600 close to the central axis of the circular through hole 501. A sliding plate 8 is provided between the two sliding grooves and is slidably connected. A screw rod 9 is placed coaxially in any one of the sliding grooves. The screw rod 9 passes through the sliding plate 8 and is threadedly connected thereto. The lower end of the screw rod 9 is connected to a second rotating motor 10, and the second rotating motor 10 is fixed to the bottom plate 100. During riveting, the water outlet pipe is located above the sliding plate 8. The screw rod 9 is driven by the second rotating motor 10, and the screw rod 9 drives the sliding plate 8 for screw transmission, so that the upper end surface of the sliding plate 8 abuts against the lowermost part of the water outlet pipe to support the water outlet pipe and prevent the water outlet pipe from sliding downward during stamping.
[0045] The fixing frame 200 includes a pair of vertically placed support rods. A hanging plate is fixed to the upper ends of the two support rods, and the first telescopic cylinder 300 is fixed to the lower end of the hanging plate.
[0046] A connecting member 11 is fixed to the mounting plate 401, and both ends of the connecting member 11 are slidably connected to the two support rods respectively, which can improve the guiding property during the movement of the riveting head assembly 400.
