[0046] To make the technical problems to be solved, the technical solutions, and the beneficial technical effects of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit the scope of protection of this application.

[0047] Figure 1 A first example of the deburring device of this application is illustrated schematically. The deburring device is particularly suitable for deburring fuel cell housings. However, it is also conceivable that the deburring device is suitable for deburring other mechanical parts.

[0048] like Figure 1 As shown, the deburring device includes:

[0049] Carrier 1;

[0050] At least two spraying units 2 can be simultaneously disposed on the carrier 1, and the spraying unit 2 is configured to spray jets for deburring.

[0051] The deburring device is configured such that, when at least two spraying units 2 are simultaneously disposed on the carrier 1, one of the spraying units 2 can protrude beyond the carrier 1 in the axial direction 21 along the longitudinal axis 20 of the spraying unit 2 to perform deburring.

[0052] Compared to a carrier 1 that can only support one spray unit 2, especially a carrier 1 that can simultaneously support at least two spray units 2, it is convenient to select a suitable spray unit 2 without having to disassemble and install it. In particular, by having one spray unit 2 protrude beyond the carrier 1 beyond the other spray units 2 along its longitudinal axis 20, the spray unit 2 can (especially along its longitudinal axis 20) extend into the interior of the component for deburring, with the other spray units 2 providing minimal obstruction. This is particularly advantageous in scenarios requiring precise deburring, where, unlike conventional methods, the spray unit 2 does not simply flush away burrs from a distance, but rather extends into the component and is very close to the burr area to precisely deburr with a jet.

[0053] "One injection unit 2 can protrude beyond the carrier 1 in the axial direction 21 along the longitudinal axis 20 of the injection unit 2," which is specifically understood to mean that, in the axial direction 21, the degree to which the one injection unit 2 protrudes beyond the carrier 1 exceeds the degree to which the other injection units 2 protrude beyond the carrier 1. Here, with respect to the axial direction 21, the other injection units 2 may or may not protrude beyond the carrier 1. Figure 1 For example, in Figure 1 Only the axial direction 21 of the longitudinal axis 20 of the downward spraying unit 2 is shown. Along the axial direction 21 shown, the downward spraying unit 2 protrudes from the carrier 1, while the rightward spraying unit 2 does not protrude from the carrier 1 along the axial direction 21 shown. Therefore, when the downward spraying unit 2 extends into the component along the axial direction 21 shown, the rightward spraying unit 2 does not cause obstruction.

[0054] Since this mainly concerns a protrusion relative to the carrier 1, the axial direction 21 can also be understood in particular as the axial direction 21 away from the carrier 1.

[0055] The jet is particularly a water jet, especially a high-pressure water jet, but other liquid jets or even gas jets are also conceivable. The carrier 1 may integrate a fluid supply unit to supply fluid for deburring to the jetting unit 2. The carrier 1 may also have a valve device to control the fluid supply to the jetting unit 2.

[0056] According to an exemplary embodiment of this application, the distance A (as shown in the figure, the distance A with respect to the foremost protruding end) by which the one spraying unit 2 exceeds the other spraying units 2 along the axial direction 21 of the longitudinal axis 20 of the spraying unit 2 is at least 75% of the length L of the spraying unit 2 in the axial direction 21. That is, along the corresponding axial direction 21, the overlap between the one spraying unit 2 and the other spraying units 2 is less than 25% of the length of the spraying unit 2. Thus, when the one spraying unit 2 extends into the interior of the component, the other spraying units 2 will not cause substantial interference.

[0057] According to an exemplary embodiment of this application, such as Figure 1 As shown, each of the at least two spray units 2 is able to protrude beyond the carrier 1 in the axial direction 21 along the longitudinal axis 20 of the spray unit 2 to perform deburring.

[0058] In particular, it is conceivable that each of the at least two injection units 2 can exceed the other injection units 2 without overlapping in the axial direction 21 along the longitudinal axis 20 of that injection unit 2 (see...). Figure 1 Therefore, the remaining injection units 2 will not cause any interference.

[0059] Figure 2 The diagram schematically illustrates both cases where the first injection unit 3 and the second injection unit 4 overlap along the axial direction 21 of the longitudinal axis 20 of the first injection unit 3 and cases where they do not overlap. The second injection unit 4 is shown in a blank box. In the solid line position, the second injection unit 4 overlaps with the first injection unit 3 in the axial direction 21; in the dashed line position, the second injection unit 4 does not overlap with the first injection unit 3 in the axial direction 21. Here, the overlap in the axial direction 21 is understood in particular independently of the positions of the first injection unit 3 and the second injection unit 4 in a plane perpendicular to the axial direction 21.

[0060] According to an exemplary embodiment of this application, such as Figure 1 As shown, the at least two spray units 2 are disposed on the periphery of the carrier 1 and are offset from each other by more than 90° along the periphery of the carrier 1, and the longitudinal axis 20 of the at least two spray units 2 extends transversely to the central axis 10 of the carrier 1. This allows each spray unit 2 to conveniently protrude beyond the other spray units 2 in its axial direction 21. Figure 1 In this example, the deburring device has exactly two spray units 2. These two spray units 2 are offset from each other by exactly 90°. Figure 1In the figure, the central axis 10 is represented by a forked circle and is exemplarily perpendicular to the plane of the figure. The periphery of the carrier 1 is particularly the periphery with respect to the central axis 10.

[0061] The carrier 1 is provided with a mounting base 12 for mounting each spray unit 2 on its periphery. The at least two spray units 2 can be detachably mounted in their respective mounting bases 12.

[0062] According to an exemplary embodiment of this application, such as Figure 1 As shown, the longitudinal axis 20 of the at least two injection units 2 is perpendicular to the central axis 10 of the carrier 1 and lies in the same plane. This simplifies the structure.

[0063] Figure 3 A second example of the deburring apparatus of this application is illustrated schematically.

[0064] According to an exemplary embodiment of this application, such as Figure 3 As shown, the at least two spray units 2 are evenly distributed on the periphery of the carrier 1. Here, the at least two spray units 2 may include two, three, or four spray units 2. When there are four or fewer, it can be ensured that the spray units 2 are staggered by more than 90° from each other. Figure 3 For example, there are exactly four spray units 2 that are staggered by 90° from each other, namely the first spray unit 3, the second spray unit 4, the third spray unit 5, and the fourth spray unit 6. The at least two spray units 2 are particularly no more than six.

[0065] Figure 4 Schematic illustration Figure 3 One of the injection units is 2. Here, it is exemplarily the first injection unit 3.

[0066] According to an exemplary embodiment of this application, such as Figure 4 As shown, each of the at least two injection units 2 has a conduit 23, which has a channel 27 for the flow of deburring fluid. The conduit 23 is in particular a rigid straight conduit to facilitate insertion into the interior of the component. Since the conduit 23 is a major component of the injection unit 2, the longitudinal axis 26 of the conduit 23 corresponds to the longitudinal axis 20 of the injection unit 2.

[0067] According to an exemplary embodiment of this application, such as Figure 4As shown, at least one of the at least two spraying units 2 has a spraying needle 24 with an elongated spraying orifice 28 suitable for spraying a linear jet. The spraying needle 24 is significantly thinner than the conduit 23. A linear jet can be easily formed through the spraying needle 24, while conventional spraying orifices generally only form conical jets. Deburring can be performed more precisely with a linear jet.

[0068] According to an exemplary embodiment of this application, the longitudinal axis 25 of the injection needle 24 forms an angle (i.e., is not parallel) with the longitudinal axis 26 of the conduit 23. This facilitates deburring with the injection needle 24 after it has been inserted into the interior of the component. The angle can be, in particular, 45° or 90°, but can also be any other angle that is considered meaningful by those skilled in the art.

[0069] According to an exemplary embodiment of this application, see Figure 3 and Figure 4 The at least one spraying unit 2 can rotate relative to the carrier 1 about its longitudinal axis 20. Therefore, especially when the longitudinal axis 25 of the spraying needle 24 forms an angle with the longitudinal axis 26 of the conduit 23, the spraying needle 24 can be directed to different positions by rotating the spraying unit 2. Furthermore, when needed, the spraying unit 2 can be rotated at high speed, resulting in a high-speed rotation of the linear jet, thereby approximately achieving a three-dimensional jet and improving deburring efficiency.

[0070] According to an exemplary embodiment of this application, such as Figure 3 As shown, the spraying unit 2 includes a first spraying unit 3, which includes a first conduit 31 and a first spraying needle 32 disposed on the first conduit 31. The first spraying needle 32 extends outward at a 90° angle to the first conduit 31. The first spraying unit 3 may be non-rotatable about its longitudinal axis 20. The first spraying unit 3 can also be used, in particular, to deburr the exterior of components.

[0071] According to an exemplary embodiment of this application, such as Figure 3 As shown, the jetting unit 2 includes a second jetting unit 4, which includes a second conduit 41 and two second jetting needles 42 disposed opposite to each other on the second conduit 41. The two second jetting needles 42 extend outward at a 45° angle relative to the second conduit 41. When the second jetting unit 4 rotates at high speed, it can form a jet similar to a cone shape, for example.

[0072] According to an exemplary embodiment of this application, such as Figure 3As shown, the spray unit 2 includes a third spray unit 5, which includes a third conduit 51 and two third spray needles 52 disposed opposite to each other on the third conduit 51. The two third spray needles 52 extend outward at a 45° angle relative to the third conduit 51. The length of the third conduit 51 can be greater than the length of the second conduit 41, thereby the second spray unit 4 and the third spray unit 5 are particularly suitable for deburring at different depths within the component.

[0073] According to an exemplary embodiment of this application, such as Figure 3 As shown, the jetting unit 2 includes a fourth jetting unit 6, which includes a fourth conduit 61 and two fourth jetting needles 62 disposed opposite to each other on the fourth conduit 61. The two fourth jetting needles 62 extend outward at a 90° angle relative to the fourth conduit 61. The length of the fourth conduit 61 can be greater than that of the first conduit 31. When the fourth jetting unit 6 rotates at high speed, it can form, for example, a jet resembling a disc.

[0074] According to an exemplary embodiment of this application, such as Figure 3 As shown, the deburring device includes a motion unit 7, and the carrier 1 is disposed on the motion unit 7 and can be carried by the motion unit 7. This allows for convenient movement of the carrier 1 and the spraying unit 2 to the desired position. The motion unit 7 is particularly a four-axis, five-axis, or six-axis robotic arm. This allows for easy access to various positions in three-dimensional space to achieve precise deburring. Figure 3 Only a small portion of motion unit 7 is shown in the image. Of course, other forms of motion unit 7 are also possible.

[0075] According to an exemplary embodiment of this application, see Figure 3 The motion unit 7 includes a rotator 70 for positioning the carrier 1, the rotator 70 being configured to drive the carrier 1 to rotate about its central axis 10. This allows the different spray units 2 to face downwards for deburring. Since the parts to be deburred generally have greater weight, it is more convenient to position the parts downwards. In this case, deburring is performed with the downward-facing spray units 2. The rotator 70 is located at the end of the robotic arm. Furthermore, the robotic arm can be moved to bring the central axis 10 of the carrier 1 to a horizontal position.

[0076] Figure 5 A third example of the deburring apparatus of this application is illustrated schematically.

[0077] Figure 6 A fourth example of the deburring apparatus of this application is illustrated schematically.

[0078] According to an exemplary embodiment of this application, see Figure 5and Figure 6 The carrier 1 includes an actuator 11 for the one injection unit 2, the actuator 11 being configured to move the one injection unit 2 to protrude beyond the carrier 1 in an axial direction 21 along the longitudinal axis 20 of the injection unit 2, beyond the other injection units 2. Figure 1 and Figure 3 In the first instance, the positions of the injection units 2 relative to each other are fixed. In contrast, in the second instance... Figure 5 and Figure 6 In this configuration, one spray unit 2 can be moved relative to the other spray units 2 by the actuator 11 to reach a protruding position for deburring. When the spray unit 2 is not in use, it can be moved to a retracted position, in particular retracted into the carrier 1. Furthermore, it is particularly conceivable that each spray unit 2 is equipped with an actuator 11.

[0079] exist Figure 5 In this example, four injection units 2 are arranged side by side, and the actuator 11 is a translational actuator and is particularly used to translate the injection units 2 vertically. Figure 6 In this example, four injection units 2 are arranged around a circumference, and the actuator 11 is a flip-type actuator and is particularly used to flip the injection units 2 up or down.

[0080] Obviously, different numbers of injection units 2 and various different arrangements can be envisioned. They will not be listed here.

[0081] In context, the longitudinal axis is understood, especially in relation to the longitudinal direction.

[0082] The dimensions, quantity, position, shape, and interrelationships of the elements in the accompanying drawings should be understood as examples, not as absolute limitations of this application. Those skilled in the art can also conceive of simple variations in the dimensions, quantity, position, shape, and interrelationships of these elements without departing from the scope of protection of this application.

[0083] In the accompanying drawings, there are multiple elements that have the same function. Sometimes only some of them are labeled as examples, but those skilled in the art can identify the other elements that have the same function without any doubt by the similarity between the shapes of these elements.

[0084] Provided that it is permissible in principle, each of the cited features can be considered as an individual feature and can be combined with any other feature in any form without departing from the scope of protection of this application. If it is permissible in principle, even if not explicitly stated, a feature described for one embodiment should be considered as being arbitrarily applicable to other embodiments.

[0085] Although specific embodiments of this application are described in detail herein, they are given for illustrative purposes only and should not be construed as limiting the scope of this application. Various substitutions, modifications, and alterations can be conceived without departing from the spirit and scope of this application.
