[0019] The present invention provides a protective device for an open workbench of a numerical control processing equipment, comprising an inner protective unit 1 and an outer protective unit 2;
[0020] like Figure 1 As shown, the inner protection unit 1 includes an inner fixed baffle 1-1 and a semi-fixed baffle 1-4, the semi-fixed baffle 1-4 is fixed to one side of the inner fixed baffle 1-1, the bottom of the inner fixed baffle 1-1 and the semi-fixed baffle 1-4 are both provided with an inner anchor fixing plate 1-2, the upper part of the semi-fixed baffle 1-4 is provided with a push-pull plate 1-7, the bottom of the push-pull plate 1-7 is provided with a pulley 1-11, and a shock absorbing spring 1-12 is provided on the pulley frame of the pulley 1-11, and the shock absorbing spring 1-12 is used to absorb the push-pull baffle when it is not completely Rebound impact during horizontal movement, the top of the push-pull plate 1-7 is flush with the top of the inner fixed baffle 1-1, the pulley 1-11 slides on the support platform 1-5, the support platform 1-5 is laterally fixed to the inner side surface of the semi-fixed baffle 1-4 and the inner side surface of the inner fixed baffle 1-1, the outer side surface of the push-pull plate 1-7 is provided with a slide rail 1-9, the inner fixed baffle 1-1 is provided with a slider adapted to the slide rail 1-9, and both sides of the push-pull plate 1-4 are provided with limit side plates 1-10 for limiting the travel of the push-pull plate;
[0021] like Figure 2As shown, the outer protection unit 2 includes an outer fixed baffle 2-2 and two outer side panels 2-3 fixed on the outer frame 2-1, the two outer side panels 2-3 are respectively fixed on both sides of the outer fixed baffle 2-2, the bottoms of the outer fixed baffle 2-2 and the outer side panels 2-3 are both provided with outer anchor fixing plates 2-5, the middle part of the inner side surface of the outer fixed baffle 2-2 is provided with a guide baffle 2-7, and the guide baffle 2-7 is hinged to the outer fixed baffle 2-2.
[0022] The top of the outer frame 2-1 is provided with a top protective plate 2-4; the lower part of the outer fixed baffle 2-2 is provided with a reinforcing rib 2-6.
[0023] The inner fixed baffle plate 1-1 and the push-pull plate 1-7 both have inner viewing windows 1-3, and the outer fixed baffle plate 2-2 has outer viewing windows 2-3.
[0024] The inner protection unit 1 is provided with an L-shaped card plate 1-6, which is transversely fixed to the lower part of the inner side surface of the push-pull plate 1-7, and the lower edge of the L-shaped card plate 1-6 is located below the push-pull plate 1-7.
[0025] The outer protection unit 2 in the above structure is designed to be fixed and fixed to the factory floor by means of a ground fixing plate and expansion bolts. The inner protection unit 1 is designed to be a half-fixed and half-pushing structure, which is convenient for the operator to check the status of the tool and workpiece after pausing the equipment at any time. The shock-absorbing spring 1-12 on the pulley 1-11 at the bottom of the push-pull plate 1-7 is used to absorb the rebound impact of the push-pull baffle during the movement of the incomplete horizontal plane. The visible windows on the inner fixed baffle 1-1, the push-pull plate 1-7 and the outer fixed baffle 2-2 are designed as transparent acrylic plates of customized size riveted to the protection plate. All gaps are filled with MS930 white sealant to prevent the cutting fluid from seeping through various gaps during the splashing process. Similarly, the existence of the visual window makes it convenient for the operator to observe the status of the workpiece and tool on the workbench at any time in all directions of the machine tool, and to deal with possible abnormal situations in time.
[0026] When the above structure is working, Figure 3As shown, the inner protection unit 1 and the outer protection unit 2 are respectively fixed to the inner and outer sides of the equipment workbench 3, wherein the fixed baffle in the inner protection unit 1 is close to the inner side of the equipment workbench 3, so that the cutting fluid and iron chips intercepted by the inner protection unit 1 can fall into the machine tool chip groove 4, and the lower edge of the L-shaped card plate 1-6 overlaps the machine tool chip groove 4 on the inner side of the equipment workbench 3, and the L-shaped card plate 1-6 plays a certain supporting role for the push-pull plate 1-7; there is a certain interval between the outer protection unit 2 and the equipment workbench 3, and the guide plate on the outer protection unit 2 The outer edge of the baffle 2-7 overlaps the machine tool chip groove 4 on the outer side of the equipment workbench 3, so that the cutting fluid and iron chips intercepted by the outer protection unit 2 can fall into the machine tool chip groove 4. During the operation of the equipment, the iron chips, cutting fluid, etc. generated by high-speed cutting will eventually fall into the machine tool chip groove 4 after colliding with the baffles on both sides, and then be automatically collected to the designated storage position, which realizes the centralized collection of iron chips and cutting fluid to a large extent, saves the operator's time for cleaning iron chips after the operation is completed, and also reduces the waste caused by the cutting fluid in the splashing process.
[0027] The operator can observe the tool rotation and workpiece cutting status in real time through the visual windows on both sides. If there is any abnormal situation, the operator can pause cutting through the equipment terminal, and then push the inner handle to move the push-pull baffle away. After confirming that the tool and workpiece are correct, the baffle is restored to the state as shown in the figure, and then subsequent operations are carried out.
[0028] This device can ultimately protect the entire open workbench of the equipment, blocking the negative effects of iron chips, cutting fluid splashes, and even the breakage of tool components. It also prevents operators from inadvertently entering the equipment's danger zone during operation, which is in line with the concepts of safe production, lean management, and civilized operations advocated by major companies today.
[0029] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
