[0027] Example

[0028] Reference Figures 1-4 As an embodiment of the present invention, a protective device for CNC machine tools is provided, comprising: a control unit 100 and a protective unit 200;

[0029] The control unit 100 includes a CNC machine tool body 101 and a control panel 102 fixedly connected to one side of the CNC machine tool body 101. A machining groove 103 is provided on one side of the CNC machine tool body 101.

[0030] The protective unit 200 includes a T-shaped block 201 slidably disposed on one side of the CNC machine tool body 101. A protective plate 202 is fixedly connected to the bottom of the T-shaped block 201. An L-shaped plate 203 is fixedly connected to the bottom of the protective plate 202. A T-shaped rod 204 slidably passes through one side of the L-shaped plate 203. A circular piece 205 is fixedly sleeved on the rod surface of the T-shaped rod 204. A spring 206 sleeved on the T-shaped rod 204 is fixedly connected to one side of the circular piece 205. Two limiting holes 207 that fit the T-shaped rod 204 are opened on one side of the CNC machine tool body 101.

[0031] The control panel 102 is used to control the CNC machine tool body 101. The machining groove 103 is used to process the workpiece. When the workpiece is placed in the machining groove 103, the machining groove 103 is protected by the protective plate 202. A T-shaped slide groove that fits the T-shaped block 201 is opened on one side of the CNC machine tool body 101. The protective plate 202 can move along the T-shaped slide groove using the T-shaped block 201. The size of the protective plate 202 is larger than the size of the machining groove 103. When the protective plate 202 covers the machining groove 103, the T-shaped rod 204 is aligned with the limiting hole 207 near the control panel 102. One end of the spring 206 abuts against the side wall of the L-shaped plate 203, so that the spring 206 pushes the disc 205 to insert the T-shaped rod 204 into the limiting hole 207.

[0032] This allows the protective plate 202 to physically cover the machining groove 103, and the protective plate 202 will not be displaced due to accidental contact, so that the CNC machine tool body 101 can operate normally and ensure the safety of the operator. After the machining is completed, the T-bar 204 is pulled to disengage it from the limiting hole 207, and then the protective plate 202 can be moved. When the protective plate 202 is located above the limiting hole 207 in the direction away from the control panel 102, the T-bar 204 is released to allow it to automatically insert into the limiting hole 207, and then the machined workpiece can be taken out from the machining groove 103.

[0033] In addition, a pull ring 208 is fixedly connected to one side of the T-bar 204. The end of the T-bar 204 facing the limiting hole 207 is set in a hemispherical shape. A pressure sensor 209 is embedded inside the CNC machine tool body 101. The pressure sensor 209 is located at the opening of one of the limiting holes 207. An indicator light 210 is fixedly connected to one side of the protective plate 202.

[0034] The pull ring 208 allows the user to easily pull the T-bar 204. The hemispherical T-bar 204 facilitates insertion into the limiting hole 207. The pressure sensor 209 is located in the limiting hole 207 below the processing groove 103. When the T-bar 204 is inserted into the limiting hole 207, the hemispherical end of the T-bar 204 will contact the pressure sensor 209. The pressure sensor 209 is a device that can sense pressure signals and convert them into usable output electrical signals according to a certain rule. After the pressure sensor 209 senses pressure, the control panel 102 uses the built-in signal receiving unit to control the indicator light 210 to light up, thereby reminding the worker that the protective plate 202 has finished covering the processing groove 103. When the T-bar 204 is no longer in contact with the pressure sensor 209, the indicator light 210 will no longer light up.

[0035] Furthermore, two rubber rods 211 are fixedly connected to one side of the CNC machine tool body 101, and the T-shaped block 201 is located between the two rubber rods 211.

[0036] When the T-block 201 moves to the end of the T-shaped slide of the CNC machine tool body 101, the rubber rod 211 can buffer the impact force generated by the movement of the T-block 201, so as to reduce the impact force on the CNC machine tool body 101 after the protective plate 202 moves, and reduce the noise generated by the impact.

[0037] Furthermore, a transparent window 212 is embedded on one side of the protective plate 202, a T-shaped tube 213 is fixedly connected to the top of the inner wall of the processing groove 103, the top of the T-shaped tube 213 penetrates through the CNC machine tool body 101, multiple nozzles 214 are fixedly connected to the wall of the T-shaped tube 213, and a discharge groove 215 is fixedly connected to one side of the CNC machine tool body 101, the discharge groove 215 is connected to the bottom of the processing groove 103.

[0038] The transparent window 212 is made of explosion-proof glass, allowing observation of the workpiece's processing status. The T-shaped pipe 213 can be connected to an external water pump and supply clean water into the T-shaped pipe 213. The clean water in the T-shaped pipe 213 can be sprayed out through the spray pipe 214 to wash away the debris attached to the transparent window 212. The wastewater and debris after washing are discharged through the discharge chute 215.

[0039] During use, after the workpiece is placed in the processing groove 103, the pull ring 208 is pulled and the protective plate 202 is moved. After the protective plate 202 covers the processing groove 103, the pull ring 208 is released so that the T-shaped rod 204 is inserted into the limiting hole 207 below the processing groove 103. When the T-shaped rod 204 contacts the pressure sensor 209, the control indicator light 210 of the control panel 102 lights up, which can remind the worker that the protective plate 202 has finished covering the processing groove 103. Then the workpiece can be processed. The processing status of the workpiece can be observed through the transparent window 212. Then, the T-shaped pipe 213 is connected to an external water pump and clean water is delivered into the T-shaped pipe 213. The debris attached to the transparent window 212 can be washed off through the spray pipe 214. The washed sewage and debris are discharged through the discharge chute 215.

[0040] After processing is completed, pull the pull ring 208 to disengage the T-bar 204 from the limiting hole 207. When the T-bar 204 is no longer in contact with the pressure sensor 209, the indicator light 210 will no longer light up. Then move the protective plate 202. When the protective plate 202 is above the limiting hole 207 in the direction away from the control panel 102, release the T-bar 204 so that it automatically inserts into the limiting hole 207. Then the processed workpiece can be taken out from the processing groove 103.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
