Description

Technical Field

[0001] The present invention relates to the technical field of lathe auxiliary equipment, and particularly relates to a protective mechanism for a vertical lathe. Background Art

[0002] A vertical lathe is a device widely used in the field of machining, mainly used for machining large and heavy workpieces, such as hubs, valve bodies, and molds. Its characteristic is that the main shaft is perpendicular to the workbench, and it can withstand large cutting forces and workpiece weights. During the machining process of a vertical lathe, the protective mechanism plays a crucial role. It is used to isolate the machining area, prevent chips and coolant from splashing, protect the safety of operators, and at the same time prevent foreign objects from entering the machining area and affecting the operation of the equipment.

[0003] However, the protective mechanism of the old-fashioned vertical lathe is relatively simple. Usually, only a transparent baffle is used for protection. It not only fails to effectively block the chips and coolant splashing during the machining process, but also the chips and coolant adhere to the transparent baffle, making it inconvenient for operators to observe the state of the tool; it is difficult to provide sufficient protection when the workpiece or tool flies out, resulting in relatively large safety hazards. For example, the splashing of chips and coolant may injure the operator. Summary of the Invention

Specific implementation mode

[0036] The following further elaborates on the above-mentioned and additional technical features and advantages of the present invention with reference to the accompanying drawings.

[0037] Embodiment 1

[0038] This embodiment provides a technical solution: a protective mechanism for a vertical lathe, as Figures 1 to 8 shown, including a lifting component 1, a protective component arranged at the mobile end of the lifting component 1, a cleaning component 4, and a liquid supply component 5. Multiple components are controlled and operated through an external control panel.

[0039] The number of the lifting components 1 is set to 1 - 3, which can be set according to the size of the vertical lathe. The lifting component 1 is an existing motor and screw-type transmission structure. Additionally, a hydraulic telescopic device can also be used to meet the need for protecting different positions.

[0040] The working table of the vertical lathe is of a circular structure, and the protective component is arranged on its outer side. The protective component includes a first arc-shaped protective plate 21 fixed to the moving end of the lifting component 1. A second arc-shaped protective plate 23 is horizontally slidably arranged on the first arc-shaped protective plate 21 to form a horizontally telescopic protective structure. The upper and lower edge portions of both the first arc-shaped protective plate 21 and the second arc-shaped protective plate 23 are bent to form an L-shaped bending structure, and the L-shaped bending structure of the second arc-shaped protective plate 23 is slidably inserted into the L-shaped bending structure of the first arc-shaped protective plate 21. The L-shaped bending structures on the upper and lower sides of one end of the first arc-shaped protective plate 21 both extend horizontally to form an extension portion 22 for the second arc-shaped protective plate 23 to slide; a pulley 27 is rotatably installed on the L-shaped bending structure of the second arc-shaped protective plate 23 to reduce the friction between the two, ensuring that the second arc-shaped protective plate 23 is always stably supported and guided during the sliding process, and preventing sliding deviation or jamming; a first protective window 24 is provided on the second arc-shaped protective plate 23, and the radian of the first protective window 24 is adapted to the radian of the second arc-shaped protective plate 23. The first protective window 24 facilitates the operator to directly observe the machining condition of the lathe and improves the safety performance; the first protective window 24 is made of transparent PC board or toughened glass, which can withstand the impact of flying chips or coolant during the machining process.

[0041] The cleaning component 4 is an important functional part of the protective mechanism of the vertical lathe, which is specifically used to clean the inner wall of the first protective window 24 to prevent chips, coolant or oil stains from adhering and affecting the observation effect. The cleaning component 4 is installed on the protective component through the fixing component 3, and it is used to clean the inner wall of the first protective window 24. The cleaning component 4 is connected to an external air pump through an air pipe; the cleaning component 4 includes an inner pipe 41 fixed to the fixing component 3. The inner pipe 41 is communicated with a liquid supply component 5. An outer pipe 42 is rotatably sleeved on the outer side of the inner pipe 41, and a cleaning member is arranged on the outer side wall of the outer pipe 42;

[0042] The cleaning member includes an extension plate 43 fixed to the outer wall of the outer pipe 42. A soft wiping block 44 is installed at the end of the extension plate 43. The soft wiping block 44 is made of materials such as sponge or rubber. Inner vertical through holes 45 and outer vertical through holes 46 are respectively formed on the outer side walls of the inner pipe 41 and the outer pipe 42. A vertical slit 47 communicated with the outer vertical through hole 46 is formed in the extension plate 43. When the outer pipe 42 rotates and the cleaning member contacts the inner wall of the first protective window 24, the inner vertical through hole 45 and the outer vertical through hole 46 are butt-connected and communicated. When the angle of the outer pipe 42 is in other positions, the inner vertical through hole 45 and the outer vertical through hole 46 are staggered. And a sealing strip is arranged between the inner pipe 41 and the outer pipe 42. When the inner vertical through hole 45 and the outer vertical through hole 46 are staggered, the inner pipe 41 maintains good airtightness.

[0043] The number of cleaning parts is one, and the cleaning component 4 is installed on the first arc-shaped protective plate 21 through the fixing component 3; damping rotations (i.e., a certain force is required to rotate) are installed at both the upper and lower ends of the outer tube 42 with the first gears 48. On the inner sides of the upper and lower ends of the second arc-shaped protective plate 23, first arc-shaped racks 410 are fixed. The corresponding first gears 48 and the first arc-shaped racks 410 are located on the same horizontal line, and the torque force required for the torsional displacement between the outer tube 42 and the first gears 48 is greater than the torque force required for the torsional displacement between the inner tube 41 and the outer tube 42.

[0044] When the second arc-shaped protective plate 23 displaces along the first arc-shaped protective plate 21, the first gears 48 and the first arc-shaped racks 410 are engaged. First, it will cause the outer tube 42 to rotate until the soft wiping block 44 of the cleaning part closely adheres to the inner wall of the second arc-shaped protective plate 23, preventing the outer tube 42 from rotating. At this time, as the second arc-shaped protective plate 23 continues to displace, although the first gears 48 will also rotate, the reaction force generated by them will act on the inner walls of the second arc-shaped protective plate 23 and the first protective window 24 to clean the inner walls of the second arc-shaped protective plate 23 and the first protective window 24. At the same time, compressed air can be injected into the inner tube 41 through an external air pump, and the compressed air will be ejected through the slit 47 to wash the inner walls of the second arc-shaped protective plate 23 and the first protective window 24. That is, first, the chips and coolant on the surface are removed by compressed air flushing, and then the residual stains are wiped by the soft wiping block 44. The synergistic effect of this dual cleaning method ensures a better cleaning effect for the protective window.

[0045] The cleaning component drives the cleaning action by the sliding movement of the second arc-shaped protective plate 23, without the need for an additional motor or power supply, reducing energy consumption and meeting the industrial requirements of energy conservation and environmental protection.

[0046] The cleaning component realizes the automatic cleaning of the inner wall of the first protective window, maintains the transparency of the protective window, ensures that the operator can clearly observe the machining situation of the vertical lathe (such as the cutting state of the workpiece and the position of the tool), improves the visualization and safety of the machining process; through the through-hole design of the inner tube and the outer tube, and the vertical slit of the extension plate, the cleaning component realizes the precise spraying of the cleaning liquid, and the spraying direction is consistent with the wiping direction, enhancing the cleaning effect, avoiding the waste of cleaning liquid at the same time, and improving the resource utilization rate.

[0047] The liquid supply component 5 is installed at the air inlet end of the cleaning component 4 for supplying cleaning liquid to the cleaning component 4. The liquid supply component 5 includes a water storage tank 51 installed at the bottom of the inner pipe 41, which is connected by threads or fixed by a buckle to ensure stable installation and easy disassembly. A telescopic electric rod 52 is fixed to the bottom of the water storage tank 51 through a mounting bracket. A water pipe 53 is fixed to the telescopic end of the telescopic electric rod 52. The air inlet end of the water pipe 53 is connected to an air pump, and the water pipe 53 slidably penetrates through the bottom of the water storage tank 51 in a water-sealed manner. A rubber sealing ring is installed around the sliding hole to ensure water-sealing performance and prevent leakage of the cleaning liquid.

[0048] During use, the telescopic electric rod 52 drives the water pipe 53 to move up and down to control whether the air outlet end of the water storage tank 51 is immersed in the cleaning liquid. Control whether the air outlet end (i.e., the upper end) of the water pipe 53 is immersed in the cleaning liquid in the water storage tank 51. When the air outlet end of the water pipe 53 is immersed in the cleaning liquid, the air flow atomizes the cleaning liquid and brings it into the cleaning component 4, and finally sprays it onto the inner wall of the first protection window 24 to assist the soft wiping block 44 in cleaning chips, coolant, and oil stains. When the air outlet end of the water pipe 53 leaves the cleaning liquid, only air flow is provided. Whether to provide cleaning liquid can be selected according to whether there are stains that cannot be wiped off on the second arc-shaped protection plate 23 and the first protection window 24.

[0049] The liquid supply component 5 controls the position of the water pipe 53 through the telescopic electric rod 52, adjusts whether the air outlet end of the water pipe 53 is immersed in the cleaning liquid in the water storage tank 51, and realizes the on-demand supply of the cleaning liquid. When cleaning is required, the water pipe 53 descends to provide the cleaning liquid to assist the soft wiping block 44 in cleaning the first protection window 24. When the cleaning liquid is not required, the water pipe 53 rises to only provide air flow to dry the protection window, saving the amount of cleaning liquid used and reducing the operating cost.

[0050] Embodiment 2

[0051] This embodiment is a further optimization based on Embodiment 1. The same parts as the foregoing technical solutions will not be described herein again. As Figures 1 to 8 shown, in order to better implement the present invention, the following setting method is particularly adopted:

[0052] In this embodiment, the first arc-shaped protection plate 21 is provided with a second protection window 25. The number of cleaning parts is two. The two cleaning parts are respectively used to clean the first protection window 24 and the second protection window 25. The cleaning component 4 is switched and installed on the first arc-shaped protection plate 21 or the second arc-shaped protection plate 23 through the fixing component 3. When it is necessary to clean the first arc-shaped protection plate 21, the cleaning component 4 is switched and installed on the second arc-shaped protection plate 23 through the fixing component 3, and the cleaning component 4 is displaced synchronously with the second arc-shaped protection plate 23. When it is necessary to clean the second arc-shaped protection plate 23, the cleaning component 4 is switched and installed on the first arc-shaped protection plate 21 through the fixing component 3, and the cleaning component 4 makes a relative displacement with the second arc-shaped protection plate 23.

[0053] At both the upper and lower ends of the outer tube 42, first gears 48 are rotatably installed. At the inner sides of the upper and lower ends of the second arc-shaped protection plate 23, first arc-shaped racks 410 are fixedly installed. The corresponding first gears 48 and first arc-shaped racks 410 are located on the same horizontal line, and the torque force required for the torsional displacement between the outer tube 42 and the first gear 48 is greater than the torque force required for the torsional displacement between the inner tube 41 and the outer tube 42;

[0054] At the outer ends of both outer tubes 42, second gears 49 are damping rotatably installed. At the inner sides of the upper and lower ends of the first arc-shaped protection plate 21, second arc-shaped racks 411 are fixedly installed. The corresponding second gears 49 and second arc-shaped racks 411 are located on the same horizontal line, and the torque force required for the torsional displacement between the outer tube 42 and the second gear 49 is greater than the torque force required for the torsional displacement between the inner tube 41 and the outer tube 42.

[0055] The cleaning component 4 is fixed to the first arc-shaped protection plate 21 through the fixing component 3. When the second arc-shaped protection plate 23 displaces along the first arc-shaped protection plate 21, the first gear 48 meshes with the first arc-shaped rack 410. First, it will cause the outer tube 42 to rotate until the cleaning part closely adheres to the inner wall of the second arc-shaped protection plate 23, and prevent the outer tube 42 from rotating. At this time, as the second arc-shaped protection plate 23 continues to displace, although the first gear 48 will also rotate, the reaction force generated by it will act on the inner walls of the second arc-shaped protection plate 23 and the first protection window 24 to achieve the cleaning of the inner walls of the second arc-shaped protection plate 23 and the first protection window 24;

[0056] The cleaning component 4 is fixed to the second arc-shaped protection plate 23 through the fixing component 3. When the second arc-shaped protection plate 23 displaces along the first arc-shaped protection plate 21, the cleaning component 4 displaces synchronously with the second arc-shaped protection plate 23. The second gear 49 meshes with the second arc-shaped rack 411, driving the cleaning part on the other side to closely adhere to the inner wall of the first arc-shaped protection plate 21 to achieve the cleaning of the inner walls of the first arc-shaped protection plate 21 and the second protection window 25.

[0057] The fixing component 3 in this embodiment includes first connecting blocks 35 on the inner sides of the upper and lower ends of the first arc-shaped protection plate 21, second connecting blocks 36 fixed to the inner sides of the upper and lower ends of the second arc-shaped protection plate 23, and mounting frames. And at the sides of the corresponding first connecting blocks 35 and second connecting blocks 36 close to each other, positioning blocks 37 are fixedly installed. A clamping block 34 is arranged between the first connecting block 35 and the second connecting block 36. The clamping block 34 is provided with positioning through holes 341 corresponding to the positioning blocks 37 and having a clearance fit, and the positioning through holes 341 are only in cooperation with one positioning block 37 at the same time.

[0058] It should be noted that: to ensure the stability of the fixing component 3 when switching the fixed object, the transverse cross-section of the positioning block 37 and the positioning through-hole 341 is a polygonal structure. The distance between the corresponding first connecting block 35 and the second connecting block 36 is slightly larger than the sum of the vertical dimensions of one positioning block 37 and the clamping block 34, which can ensure that the clamping block 34 will not be sleeved with two positioning blocks 37 at the same time, and can also reduce the connection distance between the positioning block 37 and the positioning through-hole 341. At the same time, the number of fixing components 3 can be set to two; during actual production, the vertical positions of the first arc-shaped rack 410, the second arc-shaped rack 411, the first connecting block 35 and the second connecting block 36 need to be staggered to avoid interference between the various components during use.

[0059] A driving member is provided on the mounting frame. The driving member is used to drive the displacement of the clamping block 34 so that the positioning through-hole 341 cooperates with the corresponding positioning block 37 to fix the fixing component 3 to the first arc-shaped protection plate 21 or the second arc-shaped protection plate 23. The driving member includes a C-shaped tube 32 fixed to the mounting frame and a rotating shaft 33 rotatably mounted on the mounting frame. The rotating shaft 33 is located in the inner cavity of the C-shaped tube 32. Threads with opposite spiral directions are processed at both ends of the rotating shaft 33, and the two clamping blocks 34 are respectively meshed and connected with the two threads. A motor 31 for driving the rotation of the rotating shaft 33 is mounted on the mounting frame.

[0060] When the driving member is operating, it can drive the two clamping blocks 34 to move away from each other or close to each other, so as to realize clamping and fixing of the two first connecting blocks 35 or the two second connecting blocks 36 by the two clamping blocks 34, and then switch to fix them to the first arc-shaped protection plate 21 or the second arc-shaped protection plate 23. During this process, the fixing component 3 has a certain vertical displacement in size, but will eventually return to its original position due to the tight fixing of the clamping block 34 with the first connecting block 35 or the second connecting block 36. This error does not affect normal use and is a normal phenomenon.

[0061] The upper and lower sides of one end of the first arc-shaped protection plate 21 have horizontally extending extension parts 22 for the second arc-shaped protection plate 23 to slide. A position sensor 28 is installed at the end of the second arc-shaped protection plate 23; only when the position sensor 28 detects that the second arc-shaped protection plate 23 has slid in place can the driving member operate to ensure that the positioning block 37 and the positioning through-hole 341 can be smoothly inserted.

[0062] The above is only a preferred embodiment of the present invention, which is illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
