Description

Technical Field

[0001] This invention relates to the field of horizontal CNC machine tool technology, specifically to a horizontal CNC machine tool with protective functions. Background Technology

[0002] CNC machine tools are among the most widely used CNC machine tools. They are mainly used for cutting and machining the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and other machining operations.

[0003] CNC machine tools are equipped with openable protective covers. These covers can be used to shield the working openings of CNC lathes. They can protect the internal hardened guideways, linear guideways, ball screws, or transmission racks of CNC lathes from external corrosion and damage, prevent dust from spilling out, and prevent cutting fluid or iron filings from flying out of the CNC machine tool during machining. Furthermore, the protective covers are made of tempered glass, which can be used to observe the working conditions inside the CNC machine tool.

[0004] During the machining process of a CNC machine tool, cutting fluid or iron filings often splash onto the tempered glass surface of the protective cover, which can easily damage the tempered glass, cause pollution, affect the observation of the workpiece, and make it inconvenient to process the workpiece. Therefore, a horizontal CNC machine tool with protective function is proposed. Summary of the Invention

An adjustment unit for driving the worm gear and a moving unit for moving the bracket are installed at the upper end of the bracket. One end of both the adjustment unit and the moving unit extends into the lower cover.

[0007] Preferably, the adjustment unit includes two support blocks fixedly connected to both ends of the upper surface of the bracket and a transmission rod. A worm gear is rotatably connected between the two support blocks. The worm gear meshes with multiple worm wheels. One end of the transmission rod passes through the lower guard and is fixedly connected to a second bevel gear. One end of the worm gear passes through the support block and is fixedly connected to a first bevel gear. The first bevel gear meshes with the second bevel gear. A first throttle is fixedly connected to the upper end of the transmission rod. A limiting unit is installed on the moving unit to restrict the first throttle.

[0008] Preferably, the bracket is slidably connected to the inner wall of the lower baffle, the protective unit also includes a cleaning strip, the cleaning strip is installed on one side of the protective plate, the upper side wall of the lower baffle is provided with an adjustment groove and a clearance groove, the moving unit includes an adjustment block, the adjustment block is fixedly connected to the upper end of one of the support blocks, the other end of the adjustment block extends through to the outside of the adjustment groove and is fixedly connected to an adjustment plate, the adjustment block is slidably connected to the adjustment groove, the transmission rod is rotatably connected to the adjustment plate, one end of the transmission rod extends through the clearance groove and is slidably connected to it, and two second handles are fixedly connected to the outer wall of the adjustment plate.

[0009] Preferably, the adjusting plate provides shielding and protection for the clearance groove and the adjusting groove.

[0010] Preferably, the protective cover further includes multiple limiting grooves formed on the end face of the upper cover and a limiting slide rod fixedly connected to the upper side wall of the lower cover. The limiting slide rod is slidably connected to the limiting grooves, and multiple first handles are fixedly installed on the outer wall of the lower cover.

[0011] Preferably, a connecting frame is fixedly connected to the upper end of one of the support blocks near the first bevel tooth, and one end of the transmission rod passes through the connecting frame and is rotatably connected to it.

[0012] Preferably, the protective unit further includes a clearance opening and a mounting opening, both of which are opened on the side wall of the protective plate. The cleaning strip is installed in the mounting opening by bolts, and the clearance opening makes way for the cleaning strip on one of the adjacent protective plates.

[0013] Preferably, the inner wall of the lower baffle has two limiting grooves, and the adjacent surface of the bracket to the lower baffle has two limiting strips that are slidably connected to the two limiting grooves respectively.

[0014] Preferably, the limiting unit includes a support block fixedly connected to the outer wall of the adjusting plate, a transmission rod passing through the support block and rotatably connected thereto, a support plate fixedly connected to the upper end face of the support block, a limit bolt threaded through one side of the support plate, a limit arc strip rotatably connected to one end of the limit bolt, the limit arc strip abutting against the outer wall of the first throttle, a limit rod fixedly connected to the outer wall of the limit arc strip, and the other end of the limit rod passing through the support plate and slidably connected thereto.

[0015] Preferably, the lower end face of the bracket has an outlet for waste.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention provides a protective unit installed on the inner wall of the lower baffle. The protective plate in the protective unit is driven by an adjustment unit, so that when it is not necessary to observe the workpiece processing inside the CNC machine tool body through the tempered glass, the protective plate can be rotated to be parallel to the tempered glass to protect the tempered glass. Similarly, when it is necessary to observe the workpiece, the protective plate can be rotated to be perpendicular to the tempered glass, thereby improving the protection of the tempered glass and facilitating the observation of the processed workpiece.

[0017] 2. This invention, by installing cleaning strips on the protective plate, along with adjusting grooves and clearance grooves, allows the bracket to move the protective plate, enabling the cleaning strips to clean the inner wall of the tempered glass. This prevents cutting fluid or iron filings from obstructing the tempered glass and affecting the observation of the processed workpiece, thereby improving practicality.

[0018] 3. This invention uses an adjustment plate to shield and protect the clearance groove and adjustment groove, so that when the cleaning strip is moved to clean the tempered glass, the adjustment plate always shields the clearance groove and adjustment groove, thereby improving the sealing performance of the protective cover to the CNC machine tool body and reducing the possibility of dust overflow.

[0019] 4. This invention, by setting a lower baffle that slides in conjunction with a limiting slide rod and a limiting slide groove on the upper baffle, allows the lower baffle to be pulled outward when the protective cover is opened, moving it away from the CNC machine tool body. This avoids the need for a large gap between the lower baffle and the outer wall of the CNC machine tool body to allow space for its inner wall structure, which would affect the sealing performance of the shielding at the working opening of the CNC machine tool body. At the same time, when installed, the lower baffle can better shield the working opening of the CNC machine tool body, improving sealing and protection.

[0020] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures pointed out in the description, claims and drawings. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-13The horizontal CNC machine tool with protective function in this embodiment includes a CNC machine tool body 1 and a protective cover 2 installed on the CNC machine tool body 1. The protective cover 2 includes an upper cover 22 and a lower cover 21 that are slidably connected to the CNC machine tool body 1. Tempered glass 23 is embedded in the side wall of the lower cover 21. A protective unit 3 for protecting the tempered glass 23 is installed on the inner wall of the lower cover 21. The protective unit 3 includes a bracket 31 installed on the inner wall of the lower cover 21. Multiple rotating rods 33 are rotatably connected to the inner wall of the bracket 31. One end of the rotating rod 33 passes through the outside of the bracket 31 and is fixedly connected to a worm gear 34. A protective plate 32 located inside the bracket 31 is fixedly connected to the outer wall of the rotating rod 33. An adjustment unit 4 for driving the worm gear 34 and a moving unit 5 for moving the bracket 31 are installed at the upper end of the bracket 31. One end of the adjustment unit 4 and the moving unit 5 both pass through the lower cover 21.

[0025] Specifically, the structure of the horizontal CNC machine tool in this invention is similar to that of existing horizontal CNC machine tools. The main improvement of this invention lies in enhancing the protection of the tempered glass on the protective cover of the horizontal CNC machine tool to reduce damage and contamination and facilitate observation of the processed workpiece. Both the CNC machine tool body 1 and the protective cover 2 are existing technologies. The CNC machine tool body 1 has a working opening, through which the workpiece is placed into the CNC machine tool body 1 for processing. During processing, the protective cover 2 slides to the working opening to block and protect it; this will not be elaborated upon further here. If it is not necessary to observe the processed workpiece inside the CNC machine tool body 1, the adjusting unit 4 rotates multiple worm gears 34, which drive the rotating rod 33 to rotate. The rotating rod 33 drives the protective plate 32 to rotate. The protective plate 32 is rotated until it is parallel to the tempered glass 23. The protective plate 32 shields the tempered glass 23. At this time, when the CNC machine tool body 1 is processing the workpiece, if cutting fluid or iron filings splash onto the tempered glass 23, the protective plate 32 can shield the splashed cutting fluid or iron filings, preventing the cutting fluid or iron filings from splashing onto the tempered glass 23 and causing damage or contamination to the tempered glass 23. If it is necessary to observe the processed workpiece inside the CNC machine tool body 1, the protective plate 32 can be temporarily rotated to be perpendicular to the tempered glass 23, so that the workpiece inside the CNC machine tool body 1 can be observed through the gap between the tempered glass 23 and the two adjacent protective plates 32, improving the protection of the tempered glass 23 and facilitating the observation of the processed workpiece.

[0026] Specifically, the adjustment unit 4 includes two support blocks 41 fixedly connected to both ends of the upper surface of the bracket 31 and a transmission rod 44. A worm gear 42 is rotatably connected between the two support blocks 41. The worm gear 42 meshes with multiple worm wheels 34. One end of the transmission rod 44 passes through the lower baffle 21 and is fixedly connected to a second bevel gear 45. One end of the worm gear 42 passes through the support block 41 and is fixedly connected to a first bevel gear 43. The first bevel gear 43 meshes with the second bevel gear 45. A first throttle 46 is fixedly connected to the upper end of the transmission rod 44. A limiting unit 6 is installed on the moving unit 5 to limit the first throttle 46. When it is necessary to adjust the angle of the protective plate 32... During adjustment, rotating the first throttle 46 causes the transmission rod 44 to rotate, which in turn causes the second bevel gear 45 to rotate. The second bevel gear 45 then causes the first bevel gear 43 to rotate, which in turn causes the worm gear 42 to rotate. The worm gear 42 is supported by two blocks 41. The rotation of the worm gear 42 causes multiple worm wheels 34 to rotate, which in turn causes the protective plate 32 to rotate via the rotating rod 33. This allows for easy adjustment of the angle of the protective plate 32 to protect the tempered glass 23 or to open the protective plate 32. Through the tempered glass 23, the workpiece inside the CNC machine tool body 1 can be observed. The structure is simple, easy to control, and convenient to use.

[0027] Specifically, the bracket 31 is slidably connected to the inner wall of the lower baffle 21. The protective unit 3 also includes a cleaning strip 36, which is installed on one side of the protective plate 32. The upper side wall of the lower baffle 21 is provided with an adjustment groove 211 and a clearance groove 212. The moving unit 5 includes an adjustment block 51, which is fixedly connected to the upper end of one of the support blocks 41. The other end of the adjustment block 51 extends through the adjustment groove 211 and is fixedly connected to an adjustment plate 52. The adjustment block 51 is slidably connected to the adjustment groove 211. The transmission rod 44 is rotatably connected to the adjustment plate 52. One end of the transmission rod 44 extends through the clearance groove 212 and is slidably connected to it. Two second handles 53 are fixedly connected to the outer wall of the adjustment plate 52. When the protective plate 32 is rotated to be perpendicular to the tempered glass 23, the workpiece being processed inside the CNC machine tool body 1 can be observed through the tempered glass 23. If the tempered glass 23 is raised... When the cutting fluid splashes and affects the observation of the workpiece, the protective plate 32 drives the cleaning strip 36 to rotate to be perpendicular to the tempered glass 23, so that the cleaning strip 36 contacts the inner wall of the tempered glass 23. At this time, the two second handles 53 are pulled back and forth, and the second handles 53 drive the adjusting plate 52 to move. The transmission rod 44 of the adjusting plate 52 and the adjusting block 51 slide back and forth in the relief groove 212 and the adjusting groove 211 respectively. The adjusting block 51 drives the bracket 31 to slide on the inner wall of the lower cover 21 through the support block 41. The support block 41 drives the protective plate 32 to move through the rotating rod 33. The protective plate 32 drives the cleaning strip 36 to slide on the inner wall of the tempered glass 23. The material of the cleaning strip 36 can be rubber, thereby scraping off the cutting fluid splashed on the inner wall of the tempered glass 23 to keep the inner wall of the tempered glass 23 clean, so as to facilitate the observation of the workpiece processed in the CNC machine tool body 1 through the tempered glass 23.

[0028] Specifically, the adjusting plate 52 shields and protects the clearance groove 212 and the adjusting groove 211; so that when the cleaning strip 36 is moved to clean the inner wall of the tempered glass 23, the adjusting plate 52 always shields the clearance groove 212 and the adjusting groove 211, thereby improving the sealing performance of the protective cover 2 in shielding the CNC machine tool body 1, reducing the possibility of dust overflow, and increasing protection.

[0029] Specifically, the protective cover 2 also includes multiple limiting slide grooves 24 formed on the end face of the upper cover 22 and a limiting slide rod 25 fixedly connected to the upper side wall of the lower cover 21. The limiting slide rod 25 is slidably connected to the limiting slide groove 24. Multiple first handles 26 are fixedly installed on the outer wall of the lower cover 21. When it is necessary to open the working port on the CNC machine tool body 1, the first handles 26 are pulled to move the lower cover 21 outward, causing the limiting slide rod 25 to slide with the limiting slide groove 24, thereby causing the lower cover 21 and its internal structure to be misaligned with the outer wall of the CNC machine tool body 1. At this time, moving the lower cover 21 causes the upper cover 22 to be aligned with the CNC machine tool body 1 through the limiting slide rod 25. The lower cover 21 slides to open the working opening on the main body 1 of the CNC machine tool, thus avoiding the need for a large gap between the lower cover 21 and the outer wall of the main body 1 to allow space for its inner wall structure. This would affect the sealing performance of the cover at the working opening of the main body 1. When it is necessary to cover the working opening of the main body 1, the lower cover 21 and the upper cover 22 are moved to correspond to the working opening of the main body 1. The lower cover 21 is pushed so that the limiting slide rod 25 slides into the limiting slide groove 24. This allows the lower cover 21 to cooperate with the upper cover 22 to cover the working opening of the main body 1 of the CNC machine tool, and the sealing and protection of the cover are good.

[0030] Specifically, a connecting frame 54 is fixedly connected to the upper end of one of the support blocks 41 near the first bevel tooth 43. One end of the transmission rod 44 passes through the connecting frame 54 and is rotatably connected to it. The connecting frame 54, together with the transmission rod 44, the adjusting plate 52, and the adjacent support block 41, supports and restricts the other end of the bracket 31, thereby improving the stability and strength of the movement of the bracket 31.

[0031] Specifically, the protective unit 3 also includes a clearance opening 35 and a mounting opening 37. Both the clearance opening 35 and the mounting opening 37 are located on the side wall of the protective plate 32. The cleaning strip 36 is installed in the mounting opening 37 by bolts. The clearance opening 35 makes way for the cleaning strip 36 on one of the adjacent protective plates 32. The cleaning strip 36 is installed in the mounting opening 37 by bolts. The mounting opening 37 can make way for the cleaning strip 36, so that the cleaning strip 36 is parallel to the outer wall of the protective plate 32. When the protective plate 32 is rotated to be parallel to the tempered glass 23, the clearance opening 35 on the protective plate 32 makes way for the cleaning strip 36 on one of the adjacent protective plates 32. When the protective plate 32 is rotated to be parallel to the tempered glass 23 to provide protection, the cleaning strip 36 will not be obstructed. The protective plate 32 can also provide protection for the cleaning strip 36, improving practicality.

[0032] Specifically, the inner wall of the lower cover 21 has two limiting grooves 7, and the adjacent surface of the bracket 31 to the lower cover 21 has two limiting strips 8 that are slidably connected to the two limiting grooves 7 respectively. When the bracket 31 moves, it drives the limiting strips 8 to slide in the limiting grooves 7. The limiting grooves 7 restrict the limiting strips 8, so that the bracket 31 maintains stability and strength.

[0033] Specifically, the limiting unit 6 includes a support block 61 fixedly connected to the outer wall of the adjusting plate 52, a transmission rod 44 passing through the support block 61 and rotatably connected to it, a support plate 62 fixedly connected to the upper end face of the support block 61, a limit bolt 63 threadedly connected and passing through one side of the support plate 62, a limit arc strip 65 rotatably connected to one end of the limit bolt 63, the limit arc strip 65 abutting against the outer wall of the first throttle 46, a limit rod 64 fixedly connected to the outer wall of the limit arc strip 65, and the other end of the limit rod 64 passing through the support plate 62 and slidably connected to it; when the protective plate 32 is turned to the steel When the tempered glass 23 is used for shielding or rotated to be perpendicular to the tempered glass 23, the limiting bolt 63 can be rotated to move the limiting arc strip 65 until the limiting arc strip 65 moves to abut against the outer wall of the first turn handle 46. When the limiting arc strip 65 moves, it drives the limiting rod 64 to slide against the support plate 62. The limiting rod 64, together with the support plate 62, can restrict the limiting arc strip 65 to prevent it from sliding. By restricting the first turn handle 46 through the limiting arc strip 65, the protective plate 32 will not rotate, avoiding accidental contact with the first turn handle 46 and affecting the angle of the protective plate 32, thus improving practicality.

[0034] Specifically, the lower end face of the bracket 31 is provided with a debris outlet 38; after the cleaning strip 36 cleans the inner wall of the tempered glass 23, the debris is discharged from the debris outlet 38 at the lower end of the bracket 31, which avoids the phenomenon that debris accumulates on the lower inner wall of the bracket 31 and affects the rotation of the protective plate 32. The movement of the bracket 31 can also shake the debris off the bracket 31, improving practicality.
