Description

Technical Field

[0001] The utility model relates to the technical field of machine tool safety protection, in particular to a safety protection cover for machining machine tool accessories. Background Art

[0002] Machine tools are important tools for processing and manufacturing, playing a significant role in industrial construction. Machine tools have diverse functions and can be divided into ordinary machine tools and numerical control machine tools. When a machine tool performs various cutting operations on a workpiece, the workpiece rotates at high speed, often accompanied by the splashing of debris in all directions, and even the situation where the workpiece breaks away from the fixture and harms the operator may occur. Setting a protective cover outside the machine tool can effectively avoid such situations.

[0003] Most of the existing machine tool safety protection covers fix two guide rails on the side of the machine tool, and then slide a protective cover with a main body of a piece of iron sheet on the guide rails, or set a protective cover similar to a box outside the machine tool. Such protective covers do play a protective role, but their structures are too single, or their volumes are relatively large, and they cannot be folded or stored when not in use, which may cause inconvenience during the cleaning and maintenance of the machine tool. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings in the prior art.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] The terms such as "upper", "lower", "left", "right", "middle", and "one" cited in the present utility model are only for the convenience of clear narration, rather than for limiting the scope of implementation of the present utility model. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present utility model.

[0023] Refer to Figures 1 - 4 , a safety protection cover for machining machine tool accessories, including a first baffle 3, a second baffle 7 and a third baffle 9. Rotating connection sleeves one 2 are rotatably installed on both sides of the first baffle 3. One side of the two rotating connection sleeves 1 is jointly rotatably connected to a sliding connection sleeve 1. A rotating shaft passing through both ends thereof is rotatably connected inside the sliding connection sleeve 1. Blocking hooks 5 are fixedly installed at both ends of the rotating shaft.

[0024] A rotating groove 6 is opened at the upper end of the first baffle 3. One end of the second baffle 7 is slidably connected to the rotating groove 6. The other end of the second baffle 7 is rotatably installed with a rotating connection sleeve two 8. The lower end of the rotating connection sleeve two 8 is rotatably connected to the third baffle 9.

[0025] Two stabilizing plates 18 are rotatably installed on one side of the first baffle 3. Rotating grooves 19 are opened on the rotating shafts of the two stabilizing plates 18. A fixing block 14 is fixedly installed on one side of the first baffle 3. A second spring 15 is fixedly installed on the upper end surface of the fixing block 14. The other end of the second spring is fixedly installed with a cross bar 17. A vertical bar 16 is fixedly installed in the middle of the cross bar 17. Both ends of the cross bar 17 are slidably connected in the rotating groove 19.

[0026] Both the second baffle 7 and the third baffle 9 are provided with through rectangular openings. Hard colorless transparent plastic plates are installed in the rectangular openings. When using the machine tool for machining, workers can directly observe the machining process through the hard colorless transparent plastic plates. If this setting is not made, workers must observe from the side when observing, which is very inconvenient.

[0027] Two through circular openings are opened in the sliding connection sleeve 1. The two circular openings are parallel to each other. When installing the present utility model, two parallel round bars need to be fixedly installed on the side of the machine tool first, so that the sliding connection sleeve 1 is sleeved on the surfaces of the two round bars through the two circular openings. When in use, the sliding connection sleeve 1 can slide on the two round bars (refer to the attached Figure 2 ).

[0028] A spring box 11 is fixedly mounted on one side of the second baffle 7 , a first spring 12 is fixedly mounted on the inner wall of the spring box 11 , a blocking block 13 is fixedly connected to the other side of the first spring 12 , and a hook is fixedly mounted on the surface of the blocking block 13 .

[0029] (As attached Figure 1 ) The upper end of the rotating connecting sleeve 2 8 is fixedly provided with a transverse limiting plate parallel to the upper end face of the second baffle 7, and the lower end of the rotating connecting sleeve 2 8 is fixedly provided with a longitudinal limiting plate parallel to the left end face of the third baffle 9. The transverse limiting plate can prevent the rotating connecting sleeve 2 8 from swinging to the left, and the longitudinal limiting plate can prevent the third baffle 9 from swinging to the left. If the workpiece breaks and flies out during the processing, the broken workpiece will have a large impact force. If the third baffle 9 is not restricted by the transverse limiting plate and the longitudinal limiting plate, when the broken workpiece flies out, it hits the third protective plate 9 and causes it to move outward, and it cannot provide effective protection for the workers.

[0030] The rotation axes of the two stabilizing plates 18 are symmetrically arranged with respect to the axis of the second spring 15, and the two rotating grooves 19 are also symmetrically arranged. Figure 3 and attached Figure 4 ) The rotation angle of the two stabilizing plates 18 is 90 degrees, and the rotation angle of the two rotating grooves 19 is also 90 degrees. The two stabilizing plates 18 can play the role of stabilizing the structure, and when the second baffle 7 and the first baffle 3 are folded, that is, when the second baffle 7 is flipped, the lower end surface of the second baffle 7 leaves the upper end surface of the stabilizing plate 18, so that the vertical rod 16 that originally rested on the lower end surface of the second baffle 7 loses its upward position restriction, and the cross bar 17 fixedly connected to the vertical rod 16 rises under the elastic force of the second spring 15. During the rising process of the cross bar 17, the left and right ends of the cross bar 17 also slide in the rotating groove 19. When the cross bar 17 rises to the highest point, the rotating shaft where each rotating groove 19 is located can be rotated 90 degrees, and each stabilizing plate 18 can also be rotated 90 degrees, so that the stabilizing plate 19 is transformed from an expanded state to a retracted state that fits the first baffle 3, realizing the automatic retraction function of the stabilizing plate 19 and saving volume.

[0031] First clamping columns 4 are fixedly mounted on both sides of the first baffle 3 , and the two first clamping columns 4 are both clamped in the blocking hooks 5 .

[0032] A second clamping column 10 is fixedly mounted on one side of the third baffle 9 .

[0033] In the present invention, when it is necessary to fold the entire device, first rotate the third baffle 9 in the counterclockwise direction (see the attached diagram). Figure 1), the third baffle 9 drives the second latch 10 to rotate synchronously, so that the second latch 10 is clamped with the hook fixedly installed on the surface of the blocking block 13, and then the connecting end of the second baffle 7 and the first baffle 3 moves along the rotating groove 6 and flips the second baffle 7, so that the first baffle 3 and the second baffle 7 are fitted together, thus completing the folding.

[0034] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and other terms shall be understood in a broad sense.

[0035] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
