[0029] Please also read Figures 1 to 4, the retractable protective plate provided by the utility model is now described. The retractable protective plate includes a first cover body 1, a second cover body 2 and a third cover body 3 whose plate surfaces are parallel to each other, the axis of the lathe spindle is taken as the first axis, the plate surfaces of the first cover body 1, the plate surfaces of the second cover body 2 and the plate surfaces of the third cover body 3 are all parallel to the first axis, and can all move along the first axis, the first cover body 1 is provided with a first card slot 11 extending along the first axis on the outside, the second cover body 2 is provided with a first card rail 21 extending along the first axis on the inside, the second cover body 2 is provided with a second card slot 22 extending along the first axis on the outside, and the third cover body 3 is provided with a second card rail 31 extending along the first axis on the inside, the first card rail 21 is slidably adapted in the first card slot 11, and the second card rail 31 is slidably adapted in the second card slot 22; the first cover body 1, the second cover body 2 and the third cover body 3 have an expanded state of sliding and expanding in sequence along the first axis, and a contracted state of sliding and contracting along the first axis.
[0030] Compared with the prior art, the retractable protective plate in the present embodiment can protect the spindle of the lathe and the parts processed by the lathe when in the expanded state, to prevent injuries to operators near the lathe due to emergencies during the operation of the lathe. At the same time, the retractable protective plate in the present embodiment can also reveal the spindle of the lathe and the parts being processed through its own contraction and movement. There is no need to move the protective plate to other positions outside the lathe body, which not only saves the overall space occupied by the lathe, but also helps to solve the technical problems that the existing translational protective cover cannot be fully translated, and the protective cover after full translation will occupy external space, making the processing of parts on the lathe and the maintenance of the lathe more convenient.
[0031] Based on the above embodiment, a feasible implementation method is proposed. Specifically, a first roller 15 is provided at the top of the first cover 1, a second roller 16 is provided at the bottom of the first cover 1, a third roller 35 is provided at the top of the third cover 3, and a fourth roller 36 is provided at the bottom of the third cover 3. The first roller 15 and the third roller 35 are rollingly arranged on the top of the lathe along the first axis, and the second roller 16 and the fourth roller 36 are rollingly arranged on the bottom of the lathe along the first axis. As set above, this embodiment can guide the movement of each plate body by rolling each roller on the lathe, and the rolling connection of the rollers in this embodiment can make the movement of each plate body on the lathe smoother, and prevent the plate body from being stuck at a certain position on the lathe.
[0032] In some embodiments, the middle of the first cover 1, the middle of the second cover 2, and the middle of the third cover 3 all protrude in a direction away from the main axis of the lathe. Compared with the prior art, this embodiment can increase the processing space of the lathe by optimizing the shape of each plate, and prevent the protection of each plate from causing inconvenience to the part processing process of the lathe.
[0033] Preferably, in order to enhance the structural rigidity of the first cover body 1, the second cover body 2 and the third cover body 3, the first cover body 1 is provided with a first rib 14 extending in the up-down direction on the outer side, the second cover body 2 is provided with a second rib 25 extending in the up-down direction on the outer side, the second rib 25 is perpendicular to the second cover body 2, and the third cover body 3 is provided with a third rib 34 extending in the up-down direction on the outer side. The ribs provided in this embodiment can not only enhance the structural rigidity of each plate body, but also limit the translation distance of each plate body to prevent each plate body from sliding arbitrarily along the first axis.
[0034] Based on the above embodiment, a first buffer pad 251 is provided on the side of the second rib 25 facing the first rib 14, and a second buffer pad 341 is provided on the side of the third rib 34 facing the second rib 25. In this embodiment, the arrangement of the first buffer pad 251 and the second buffer pad 341 can prevent a hard collision between the plates, making the structural arrangement of the retractable protective plate in the utility model more reasonable.

[0036] In some embodiments, the first rib 14 is provided with a positioning hole, and the positioning hole is used to fix the first cover body 1 to the lathe. In this embodiment, by providing the positioning hole, it is convenient to position the first cover body 1 on the lathe by plugging and fitting the fixing member (such as a positioning bolt or a positioning pin) with the positioning hole, so as to prevent the retractable protective plate in this embodiment from moving randomly during the process of expansion or contraction.
[0037] In some embodiments, the top end of the first cover body 1 is bent inward to form a first curl 12, the bottom end of the first cover body 1 is bent outward to form a second curl 13, the top end of the second cover body 2 is bent inward to form a third curl 23, the bottom end of the first cover body 1 is bent outward to form a fourth curl 24, the top end of the third cover body 3 is bent inward to form a fifth curl 32, and the bottom end of the first cover body 1 is bent outward to form a sixth curl 33. The folds of the first curl 12, the second curl 13, the third curl 23, the fourth curl 24, the fifth curl 32, and the sixth curl 33 are all parallel to the first axis.
[0038] Compared with the prior art, the first curl 12 and the second curl 13 in the present embodiment can enhance the structural rigidity of the first cover body 1, the third curl 23 and the fourth curl 24 can enhance the structural rigidity of the second cover body 2, and the fifth curl 32 and the sixth curl 33 can enhance the structural rigidity of the third cover body 3, thereby preventing the various plates from being dislocated due to insufficient rigidity during movement, and helping to prevent the various plates from resisting deformation when impacted by external objects.
[0039] Based on the above embodiment, the first curl 12 is slidably inserted in the third curl 23, the fourth curl 24 is slidably inserted in the second curl 13, the third curl 23 is slidably inserted in the fifth curl 32, and the sixth curl 33 is slidably inserted in the fourth curl 24. In more detail, the first curl 12 is slidably adapted in the first groove formed by the third curl 23, the fourth curl 24 is slidably adapted in the second groove formed by the second curl 13, the third curl 23 is slidably adapted in the third groove formed by the fifth curl 32, and the sixth curl 33 is slidably adapted in the fourth groove formed by the fourth curl 24. Compared with the prior art, this embodiment can guide the relative movement of each plate body by mutual adaptation of each curl, and not only that, it can also prevent the position of each plate body from deviating when moving or being impacted.
[0040] Based on the same inventive concept, the utility model also proposes a roller lathe, which includes the retractable protective plate mentioned above.
[0041] Compared with the prior art, the roller lathe in the utility model has all the benefits of the above-mentioned retractable protective plate, which will not be described here in detail.
[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
