Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example

[0027] Reference Figure 1-Figure 5 This embodiment provides a sheet metal frame for parts processing, including a bottom plate 1, a panel 2 and a processing table 3, wherein the processing table 3 is provided with a groove 4; the panel 2 is vertically slidably mounted on the processing table 3, more specifically, the panel 2 is door-shaped, a door-shaped hole is provided in the processing table 3, and the panel 2 is slidably mounted at the door-shaped hole. The purpose of setting the panel 2 into a door shape is, for example Figure 1 As shown in the figure, the side without the enclosure 2 is the workpiece loading and unloading side. Since the enclosure 2 is not provided, it is more convenient to load and unload parts. The bottom plate 1 is connected to the processing table 3 through a symmetrically arranged connecting rod mechanism. In order to improve stability, multiple groups of connecting rod mechanisms are arranged side by side. The connecting rod mechanism includes a bearing seat 1 5 fixedly connected to the bottom plate 1, the bearing seat 1 5 is rotatably connected to a rotating shaft 1 6, the rotating shaft 1 6 is fixed with one end of an adjusting rod 1 7, the other end of the adjusting rod 1 7 is rotatably connected to one end of an adjusting rod 2 8, the other end of the adjusting rod 2 8 is fixed with a rotating shaft 2 9, and the rotating shaft 2 9 is rotatably connected to the bearing seat 2 10 fixed at the bottom of the processing table 3. More specifically, the other end of the adjusting rod 1 7 and one end of the adjusting rod 2 8 are both inclined toward the middle of the bottom plate 1 and the processing table 3. The purpose of this arrangement is that when the processing table 3 is folded, the adjusting rod 1 7 and the adjusting rod 2 8 rotate toward the middle of the bottom plate 1 and the processing table 3, and on the basis of the space occupied by the bottom plate 1 and the processing table 3, the adjusting rod 1 7 and the adjusting rod 2 8 will not increase additional space.

[0028] The bottom of the processing table 3 is rotatably connected with a rotating shaft 3 11, and the rotating shaft 3 11 is connected to the rotating shaft 2 9 through a bevel gear set 2 31. More specifically, the bevel gear set 2 31 is two bevel gears, and a gear 12 is fixed to one end of the rotating shaft 3 11. The bottom of the processing table 3 is slidably connected with a rack 13, and the rack 13 is meshed with the gear 12. The rack 13 is fixedly connected with a driving shaft 14. The enclosure 2 is provided with a guide hole 1, and the driving shaft 14 passes through the guide hole 1. The guide hole 1 includes an inclined section 15, and there is an angle between the inclined section 15 and the moving trajectory of the driving shaft 14; the guide hole 1 also includes a horizontal section 16. When the driving shaft 14 is on the horizontal section 16, the enclosure 2 protrudes from the processing table 3, and the horizontal section 16 coincides with the moving trajectory of the driving shaft 14, and the inclined section 15 is inclined upward away from one end of the horizontal section 16;

[0029] In this embodiment, if Figure 1As shown, the adjusting rod 1 7 and the adjusting rod 2 8 form a V shape. When the distance between the bottom plate 1 and the processing table 3 decreases, the rotating shaft 2 9 located on the left side rotates counterclockwise. Driven by the bevel gear set 2 31, the rotating shaft 3 11 and the gear 1 12 rotate. Since the gear 12 is meshed with the rack 13, and the rack 13 is slidably connected with the processing table 3, the rack 13 can move. When the rack 13 moves, it drives the driving shaft 14 to move, as shown in FIG. Figure 2 and Figure 5 In the state shown, the enclosure 2 passes through the horizontal section 16 and the inclined section 15 of the guide hole 1 successively. When passing through the horizontal section 16, since the moving trajectory of the horizontal section 16 coincides with that of the driving shaft 14, it will not affect the height of the enclosure 2, that is, the relative position of the enclosure 2 and the processing table 3 remains unchanged. When passing through the inclined section 15, since the end of the inclined section 15 away from the horizontal section 16 is inclined upward, the enclosure 2 moves downward relative to the processing table 3 when passing through the inclined section 15. When the distance between the processing table 3 and the bottom plate 1 is the smallest, the bottom end of the enclosure 2 is completely moved into the inside of the processing table 3. In summary, when the height of the processing table 3 is adjusted to the folded state, the relative position of the enclosure 2 and the processing table 3 remains unchanged at first. In this process, the height of the processing table 3 can be adjusted to adapt to different users, and then the enclosure 2 descends relative to the processing table 3.

[0030] As a preferred solution of the present invention, a gear 2 17 is fixed to the other end of the rotating shaft 3 11, a rack 2 18 is slidably connected to the bottom of the processing table 3, the rack 2 18 is meshed with the gear 2 17, the rack 2 18 is fixedly connected to the driving shaft 2 19, the groove 4 is connected to the bottom surface of the processing table 3, a top block 20 is slidably connected to the groove 4, the top block 20 is provided with a guide hole 2, the end of the driving shaft 2 19 extends into the guide hole 2, the guide hole 2 includes a horizontal section 21 and an inclined section 22, when the driving shaft 2 19 is on the horizontal section 21, the top of the top block 20 is in the groove 4, and the moving trajectory of the driving shaft 2 19 coincides with the horizontal section 21; the inclined section 22 is away from the horizontal section 21 and tilted downward;

[0031] In this embodiment, if Figure 1 , Figure 3 and Figure 4 As shown, when the distance between the bottom plate 1 and the processing table 3 decreases, the rotating shaft 2 9 on the left side rotates counterclockwise, and driven by the bevel gear set 2 31, the rotating shaft 3 11 and the gear 2 17 rotate. Since the gear 2 17 is meshed with the rack 2 18, and the rack 2 18 is slidably connected with the processing table 3, the rack 2 18 can move. When the rack 2 18 moves, it drives the driving shaft 2 19 to move, as shown in FIG. Figure 4In the state shown, the top block 20 passes through the horizontal section 21 and the inclined section 22 of the guide hole 2 successively. When passing through the horizontal section 21, since the horizontal section 21 coincides with the moving trajectory of the push shaft 2 19, it will not affect the top block 20, that is, the relative position of the top block 20 and the processing table 3 remains unchanged. When passing through the inclined section 22, since the inclined section 22 is inclined downward away from the end of the horizontal section 16, the top block 20 moves upward relative to the processing table 3 when passing through the inclined section 22. When the distance between the processing table 3 and the bottom plate 1 is the smallest, the top end of the top block 20 is flush with the top end of the processing table 3. In summary, when the height of the processing table 3 is adjusted to the folded state, the relative position of the top block 20 and the processing table 3 remains unchanged at first. In this process, the height of the processing table 3 can be adjusted to suit different users. Then the top block 20 rises relative to the processing table 3 to eject the parts in the groove 4.

[0032] As a preferred embodiment of the present invention, it also includes a power mechanism, which includes a bearing seat three fixed on the base plate 1, the bearing seat three is rotatably connected to a connecting shaft 23, the connecting shaft 23 is fixedly connected to one end of a driving rod 24, the other end of the driving rod 24 is rotatably connected to one end of a driving rod 25, the other end of the driving rod 25 is fixed to a connecting shaft 2, and the connecting shaft 2 is rotatably connected to a bearing seat four 26 fixed at the bottom of the processing table 3; the power mechanism also includes a bearing seat five, the bearing seat five is rotatably connected to a support shaft 27, the support shaft 27 is fixed with a worm 28, and the connecting shaft 23 is fixed with a worm wheel 29 meshing with the worm 28; the base plate 1 is rotatably connected to a handwheel through a bearing seat six, and the handwheel and the worm 28 are connected through a bevel gear set 30.

[0033] In this embodiment, the driving rod 1 24 and the driving rod 2 25 form a V shape, and the driving rod 1 24 and the driving rod 2 25 are not parallel to the adjusting rod 1 7 and the adjusting rod 2 8. Under the action of the bevel gear set 1 30, the rotation directions of the hand wheel and the adjusting rod 1 7, the adjusting rod 2 8 and the driving rod 1 24 are staggered. When it is necessary to adjust the height of the processing table 3, the hand wheel is rotated to rotate the worm gear 29, and the worm gear 29 drives the connecting shaft 1 23 and the driving rod 1 24 to rotate. The driving rod 1 24 and the driving rod 2 25 are not parallel to the adjusting rod 1 7 and the adjusting rod 2 8, so under the push of the driving rod 2 25, the height of the processing table 3 changes.

[0034] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
