Description

Technical Field

[0001] This utility model belongs to the field of CNC machine tool technology, and specifically relates to a protective device for CNC lathe machining. Background Technology

[0002] CNC lathes are among the most widely used machine tools, primarily used for machining various parts, especially complex, precision, small-batch, and multi-variety parts. Through numerical control technology, they automatically process parts according to pre-programmed machining programs, solving machining problems that traditional machine tools struggle with. CNC lathes are generally equipped with safety devices to ensure operator safety during operation, and typically include observation windows for clear monitoring of the machining process.

[0003] In existing CNC machine tool protective devices, coolant and metal shavings splashed during machining tend to adhere to the surface of the observation window, forming stains that obstruct the view. This prevents operators from clearly observing the workpiece machining process, affecting machining accuracy and equipment monitoring. The observation window needs to be manually wiped after the machine is stopped, which is not very practical.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is a protective device for CNC lathe machining, including a protective shell, an openable protective plate installed on the protective shell, an observation window provided on the protective plate, a drive assembly installed on the inner wall of the protective plate, a moving assembly installed on the drive assembly, a sponge plate provided on the moving assembly, the sponge plate being in close contact with the surface of the observation window, the drive assembly being used to drive the moving assembly to move back and forth, so as to drive the sponge plate to perform cleaning operations on the observation window, a storage box and an opening and closing structure are installed on the moving assembly, the storage box being used to store cleaning fluid, and a control component is also installed on the inner wall of the protective plate, the control component being used to control the intermittent misalignment movement of the opening and closing structure when it moves with the moving assembly, so that the opening and closing assembly can intermittently control the storage box to inject cleaning fluid into the sponge plate.

[0006] The movable component includes a mounting plate, a sponge plate is placed on the mounting plate, a movable block is mounted on one end of the mounting plate, and a positioning block is mounted on the other end.

[0007] The drive assembly includes a drive structure and a positioning element, with the positioning block and the positioning element being slidably connected.

[0008] The drive structure includes a drive unit and a positioning plate. Both the drive unit and the positioning plate are installed on the inner wall of the protective plate. A reciprocating screw is coaxially installed on the drive end of the drive unit. One end of the reciprocating screw is rotatably mounted on the positioning plate, and the moving block is threadedly connected to the reciprocating screw.

[0009] The mounting plate has multiple through holes evenly distributed. The storage box is mounted on the mounting plate, and the through holes communicate with the inner cavity of the storage box so that the cleaning fluid in the storage box can be injected into the sponge board. The opening and closing structure can completely cover all the through holes. A sealing cap is threaded on the inlet end of the storage box.

[0010] The opening and closing structure includes a sliding rod that is slidably mounted through one end of the mounting plate. A mounting frame is mounted on one end of the sliding rod, and the mounting frame is evenly equipped with the same number of blocking plates as the through holes. The blocking plates are all in close contact with the surface of the mounting plate, and each blocking plate corresponds to one through hole and can completely cover it. A protrusion is mounted on the other end of the sliding rod. The protrusion itself is trapezoidal. The opening and closing structure also includes springs, with at least two springs. One end of the spring is fixed to one end of the mounting plate, and the other end is fixed to one end of the protrusion.

[0011] The control components include a control board, which is installed on the inner wall of the protective plate. Multiple control blocks are evenly arranged on the control board. The control blocks are trapezoidal in shape, and the protrusions can slide and engage with the control blocks.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model uses a drive device to rotate a reciprocating screw, so that the mounting plate can drive the sponge plate to repeatedly wipe the inner wall of the observation window, ensuring that the observation window is in a clear state. The operator can always clearly see the processing status of the workpiece inside the protective shell without stopping the machine to manually wipe the observation window. At the same time, by injecting the cleaning fluid stored in the storage box into the sponge plate, the cleaning ability of the sponge plate can be further improved, and the cleaning efficiency and effect can be improved.

[0014] 2. This utility model utilizes a protrusion that, driven by the mounting plate, can intermittently slide in conjunction with the control block. Furthermore, the compression and release of a spring allows the blocking plate and the through-hole to intermittently shift, allowing the cleaning fluid stored in the storage tank to be intermittently injected into the sponge plate. This intermittent injection method ensures that the sponge plate is filled with cleaning fluid during cleaning operations to improve clarity, while preventing over-injection and overflow. Additionally, when the observation window is not being wiped, cleaning fluid will not be injected into the sponge plate, reducing waste and improving practicality.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-9 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0027] Please see Figures 1-3 As shown:

[0028] This embodiment provides a protective device for CNC lathe machining, including a protective shell 1, an openable protective plate 2 installed on the protective shell 1, an observation window 3 provided on the protective plate 2, a drive assembly 4 installed on the inner wall of the protective plate 2, a moving assembly 5 installed on the drive assembly 4, a sponge plate 6 provided on the moving assembly 5, the sponge plate 6 being in close contact with the surface of the observation window 3, the drive assembly 4 being used to drive the moving assembly 5 to reciprocate, so as to drive the sponge plate 6 to perform cleaning operations on the observation window 3, a storage box 7 and an opening and closing structure 8 are installed on the moving assembly 5, the storage box 7 is used to store cleaning fluid, and a control component 9 is also installed on the inner wall of the protective plate 2, the control component 9 being used to control the opening and closing structure 8 to move intermittently in a staggered manner when it follows the moving assembly 5, so that the opening and closing assembly can intermittently control the storage box 7 to inject cleaning fluid into the sponge plate 6, and in the initial state, the storage box 7 will be blocked by the opening and closing assembly and will not be able to inject cleaning fluid into the sponge plate 6.

[0029] When the observation window 3 is contaminated by coolant or metal scraps, the operator can start the drive component 4 to move the moving component 5, so that the moving component 5 can move the sponge plate 6 to repeatedly clean the inner wall of the observation window 3, and perform cleaning operations on the observation window 3 to ensure that the observation window 3 is in a clear state. The operator can always clearly see the processing status of the workpiece inside the protective shell 1 without stopping the machine to manually wipe the observation window 3.

[0030] Furthermore, when the moving component 5 moves, the opening and closing structure 8 also moves accordingly. As a result, the opening and closing structure 8 is driven by the control component 9 to perform intermittent staggered movements, so that the cleaning fluid in the storage box 7 can be intermittently injected into the sponge plate 6. The cleaning fluid improves the cleaning effect of the sponge plate 6. The opening and closing structure 8 is designed to ensure that the sponge plate 6 is filled with cleaning fluid during cleaning operations to improve the cleaning effect, while avoiding the problem of excessive injection of cleaning fluid and overflow. At the same time, the cleaning fluid will not be injected into the sponge plate 6 when the observation window 3 is not being wiped, reducing waste and improving practicality.

[0031] like Figure 2 , Figure 3 , Figure 4 , Figure 8 As shown, the moving component 5 includes a mounting plate 10, a sponge plate 6 is disposed on the mounting plate 10, a moving block 11 is mounted on one end of the mounting plate 10, and a positioning block 12 is mounted on the other end. The driving component 4 includes a driving structure 13 and a positioning element 14. The positioning block 12 and the positioning element 14 are slidably connected. The driving structure 13 includes a driving device 15 and a positioning plate 16. The driving device 15 includes, but is not limited to, a motor. The driving device 15 and the positioning plate 16 are both mounted on the inner wall of the protective plate 2. A reciprocating screw 17 is coaxially mounted on the driving end of the driving device 15. One end of the reciprocating screw 17 is rotatably disposed on the positioning plate 16 to ensure the stability of the reciprocating screw 17 during operation. The moving block 11 is threadedly connected to the reciprocating screw 17.

[0032] Start the drive device 15 to drive the reciprocating screw 17 to rotate, thereby moving the mounting plate 10. The positioning component 14 can ensure that the mounting plate 10 moves back and forth smoothly, so that the mounting plate 10 drives the sponge plate 6 to repeatedly wipe the inner wall of the observation window 3 to ensure its clarity.

[0033] like Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 As shown, the mounting plate 10 has multiple through holes 18 evenly distributed on it. The storage box 7 is mounted on the mounting plate 10, and the through holes 18 communicate with the inner cavity of the storage box 7 so that the cleaning fluid in the storage box 7 can be injected into the sponge plate 6. The opening and closing structure 8 can completely cover all the through holes 18. When the mounting plate 10 is not moved by the reciprocating screw 17, the opening and closing structure 8 is in a state of completely covering all the through holes 18. When the mounting plate 10 is moved by the reciprocating screw 17, and the sponge plate 6 is used for wiping the observation window 3, the opening and closing structure 8 will move with the mounting plate 10. During the movement of the opening and closing structure 8, the control component 9 will drive it to move intermittently in a staggered manner, so that the opening and closing structure 8 intermittently releases the cover of the through hole 18, allowing the cleaning fluid stored in the storage box 7 to be intermittently injected into the interior of the sponge plate 6. In this intermittent injection method, while ensuring that the interior of the sponge plate 6 is filled with cleaning fluid to improve the cleaning effect, it can avoid the problem of excessive injection of cleaning fluid and overflow. At the same time, when the sponge plate 6 is not wiping the observation window 3, the cleaning fluid will not be injected into the interior of the sponge plate 6, reducing waste and improving practicality.

[0034] A sealing cap 19 is threaded on the inlet end of the storage box 7. The sealing cap 19 can seal the inlet end of the storage box 7 to prevent the internal cleaning fluid from spilling out. When it is necessary to pour cleaning fluid into the storage box 7, the sealing cap 19 can be turned by thread to release its sealing effect on the inlet end of the storage box 7.

[0035] like Figures 2-9As shown, the opening and closing structure 8 includes a sliding rod 20, which is slidably mounted on one end of the mounting plate 10. A mounting frame 21 is mounted on one end of the sliding rod 20. The mounting frame 21 is evenly equipped with the same number of blocking plates 22 as the through holes 18. Each blocking plate 22 is in close contact with the surface of the mounting plate 10, and each blocking plate 22 corresponds to one through hole 18 and completely covers it. A protrusion 23 is mounted on the other end of the sliding rod 20. The protrusion 23 is trapezoidal in shape. The opening and closing structure 8 also includes springs 24, with at least two springs. One end of each spring 24 is fixed to one end of the mounting plate 10, and the other end is fixed to one end of the protrusion 23. The control component 9 includes a control plate 26, which is mounted on the inner wall of the protective plate 2. Multiple control blocks 25 are evenly arranged on the control plate 26. The control blocks 25 are trapezoidal in shape, and the protrusions 23 slide in cooperation with the control blocks 25. When the mounting plate 10 reciprocates, the entire opening and closing structure 8... The opening and closing structure 8 moves accordingly, and the protrusion slides along the control plate 26. During the movement of the protrusion 23, the trapezoidal inclined surface will contact the trapezoidal inclined surface of the control block 25, causing the protrusion 23 to move out of position. This causes the spring 24 to be compressed, and the sliding block drives the mounting frame 21 and the blocking plate 22 to move. As a result, the blocking plate 22 is misaligned with the through hole 18, allowing the cleaning fluid in the storage box 7 to be injected into the sponge plate 6 through the through hole 18. Under the continued driving of the mounting plate 10, the protrusion 23 will gradually move away from the control block 25. The spring 24 releases its compression force, driving the protrusion 23 back to its initial position, so that the blocking plate 22 covers and seals the through hole 18 again, blocking the injection of cleaning fluid into the sponge plate 6. Then, under the continuous driving of the mounting plate 10, the protrusion 23 cooperates with multiple control blocks 25 to achieve the intermittent release of the blocking plate 22 from covering the through hole 18, allowing the cleaning fluid to be injected into the sponge plate 6 intermittently.

[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
