Description
Technical Field
[0001] This utility model relates to the field of oil fume box welding and processing, and in particular to an oil fume box welding positioning device. Background Technology
[0002] The fume hood includes a front panel and side panels. The front panel has a first welded side edge, and the side panels have a second welded side edge. The processing of the fume hood involves welding the first and second welded side edges. The quality of the weld largely depends on the degree of contact between the first and second welded side edges; the closer the contact between the first and second welded side edges, the better the weld quality.
[0003] At present, the first and second welding edges are mainly pressed manually during the welding process, so the stability of the pressing force cannot be effectively guaranteed. On the one hand, it is not possible to maintain close contact between the first and second welding edges for a long time during the welding process, and on the other hand, the first and second welding edges are also prone to misalignment during the welding process.

[0041] Example:
[0042] See Figure 1 The fume box includes a front panel 100 and side panels 200. The front panel 100 is elongated and extends along a first direction. The cross-sectional shape of the front panel 100 is generally Z-shaped. Both ends of the front panel 100 have first welding side edges 101. There are two side panels 200, located at opposite ends of the front panel 100. Each side panel 200 has a second welding side edge 201, which needs to be in close contact with the corresponding first welding side edge 101 to allow for high-quality welding.
[0043] To ensure that the second welding edge 201 maintains close contact with the first welding edge 101 throughout the welding process, see [reference needed]. Figures 2-7This embodiment provides a welding positioning device for an oil fume box, including a base plate 1, a support plate 8, a first linear driver 2, a second linear driver 3, a third linear driver 4, a sixth linear driver 9, and a fourth linear driver 5.
[0044] The first direction, the second direction, and the third direction are mutually perpendicular. The substrate 1 is perpendicular to the third direction, and the support plate 8 is perpendicular to the second direction. The bottom edge of the substrate 1 is fixed to the upper surface of the support plate 8, and a magnetic suction element 81 is provided on the upper surface of the support plate 8. The first linear actuator 2, the sixth linear actuator 9, and the second linear actuator 3 are all mounted on the substrate 1, wherein the first linear actuator 2 and the second linear actuator 3 are arranged along the first direction, and the sixth linear actuator 9 is arranged along the third direction. A first pressure block 21 is provided at the output end of the first linear actuator 2, a second pressure block 31 is provided at the output end of the second linear actuator 3, and a fifth pressure block 91 is provided at the output end of the sixth linear actuator 9.
[0045] See Figures 8-12 First, the cigarette box side panel 200 is placed on the support plate 8. The magnetic suction component 81 provides weak magnetic attraction to the cigarette box side panel 200 to prevent it from tipping over on the support plate 8, thus making the cigarette box side panel 200 approximately perpendicular to the support plate 8 and the first direction. At this time, the fifth pressing block 91 abuts against the cigarette box side panel 200 along the third direction, and the cigarette box side panel 200 can be adjusted in the third direction by the fifth pressing block 91. Then, the first pressing block 21 and the second pressing block 31 begin to approach the cigarette box side panel 200 along the first direction. Finally, the first pressing block 21 and the second pressing block 31 press against the two sides of the cigarette box side panel 200 along the first direction, thereby locking the position of the cigarette box side panel 200 on the substrate 1. Correspondingly, the relative position between the second welding side edge 201 and the substrate 1 is also locked.
[0046] Preferably, the first linear driver 2 and the second linear driver 3 are coaxially arranged to avoid the first pressure block 21 and the second pressure block 31 generating a rotational torque on the side plate 200 of the cigarette box.
[0047] There are two first linear actuators 2 and two second linear actuators 3, with the two second linear actuators 3 located between the two first linear actuators 2, to lock the positions of the two cigarette box side panels 200 respectively.
[0048] See Figure 13 and Figure 14 After the two side panels 200 of the smoke box are locked in position on the base plate 1, the front panel 100 of the smoke box is placed between the two side panels 200 to allow the two first welding side edges 101 to align with the two second welding side edges 201 respectively. See Figure 4 and Figure 10The shape of the second pressure block 31 matches the shape of the front panel 100 of the cigarette box. Therefore, after the front panel 100 of the cigarette box is placed between the two side panels 200 of the cigarette box, it can obtain a certain support through the two second pressure blocks 31.
[0049] See Figure 3 , Figure 5 and Figure 7 The fourth linear actuator 5 and the third linear actuator 4 are also mounted on the substrate 1. The third linear actuator 4 is disposed along the second direction, and the fourth linear actuator 5 is perpendicular to the first direction and is inclined relative to the second and third directions. A fourth pressure block 51 is provided at the output end of the fourth linear actuator 5, and a third pressure block 41 is provided at the output end of the third linear actuator 4. (See also...) Figure 10 and Figure 14 The mounting directions of the fourth linear actuator 5 and the third linear actuator 4 are matched with the shape of the front panel 100 of the cigarette box. Therefore, the fourth pressure block 51 and the third pressure block 41 can cooperate to press on the outer surface of the front panel 100 of the cigarette box, so that the inner surface of the front panel 100 of the cigarette box is pressed on the second pressure block 31 and fully fits the second pressure block 31. Thus, the position of the first welding side edge 101 on the substrate 1 is also locked. The first welding side edge 101 and the second welding side edge 201 can maintain a stable contact state and have a high degree of overlap. At this time, high-quality welding can be performed on the first welding side edge 101 and the second welding side edge 201.
[0050] Preferred, see Figure 2 , Figure 4 and Figure 6 The fume box welding positioning device also includes a support base 6, which is mounted on the base plate 1 and located on the same side of the base plate 1 as the second pressure block 31. The support base 6 and the second pressure block 31 can cooperate to support the front panel 100 of the fume box. As a result, the possibility of the front panel 100 of the fume box slipping between the two side panels 200 of the fume box before the fourth pressure block 51 and the third pressure block 41 press against the outer surface of the front panel 100 of the fume box is effectively reduced.
[0051] For further optimization, see Figure 1 The front panel 100 of the cigarette box is provided with a guide groove 102 extending in the first direction, see [reference]. Figure 4 The support base 6 is provided with a guide post 61, which is inserted into the guide groove 102. On the one hand, it can prevent the front panel 100 of the cigarette box from slipping off the support base 6. On the other hand, the front panel 100 of the cigarette box can move on the support base 6 in the first direction so that the second welding side edge 201 can be aligned with the first welding side edge 101 before the fourth pressure block 51 and the third pressure block 41 press the front panel 100 of the cigarette box.
[0052] See Figure 2 and Figure 5In this embodiment, the fume box welding positioning device further includes a fifth linear actuator 7, which is mounted on the base plate 1 along a first direction. A connecting plate 71 is provided at the output end of the fifth linear actuator 7. The third linear actuator 4 and the fourth linear actuator 5 are both mounted on the connecting plate 71 and are connected to the base plate 1 via the connecting plate 71. The third linear actuator 4 and the fourth linear actuator 5 can move in the first direction via the fifth linear actuator 7 to avoid obstructing the fume box side plate 200 during its placement between the first pressing block 21 and the second pressing block 31.
[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
