Description

Technical Field

[0001] This utility model relates to the field of lathe auxiliary equipment technology, specifically to a vertical lathe protective device. Background Technology

[0002] Vertical lathes are widely used in machining, primarily for processing large, heavy workpieces such as wheel hubs, valve bodies, molds, and other complex components. Their main characteristic is the spindle's perpendicular design to the worktable. This layout facilitates workpiece clamping and positioning, effectively withstands large cutting forces and workpiece weight, and is suitable for heavy-duty cutting and precision machining. During the machining process on a vertical lathe, the protective mechanism plays a crucial role. Its main functions are to isolate the machining area, prevent chips and coolant from splashing, protect operators from potential injury, and prevent external foreign objects from entering the machining area, avoiding interference or damage to the equipment and ensuring the stability and safety of the machining process.

[0003] However, older vertical lathes typically lack comprehensive protective mechanisms or rely solely on simple guardrails. This approach reveals numerous shortcomings in practical use, leading to significant safety hazards during machining. For example, metal chips and coolant generated during high-speed cutting can splash in unpredictable directions. Without effective protection, these splashes can easily reach operators, causing burns, cuts, and other personal injuries, and may also contaminate the work environment. Furthermore, the exposed machining area means that the rotating spindle, cutting tools, or other moving parts are not adequately shielded, increasing the risk of accidental contact by operators. Additionally, simple guardrails often have limited strength and are insufficient to withstand the impact of accidentally ejected workpieces or tools, further exacerbating safety risks. These problems not only threaten operator safety but can also impact production efficiency and economic benefits due to machining interruptions or equipment damage. Utility Model Content

[0004] The purpose of this utility model is to provide a protective device for a vertical lathe, which solves the problem that old-fashioned vertical lathes usually lack a complete protective mechanism or only use simple baffles for blocking, resulting in significant safety hazards during the processing.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions, specifically including:

[0006] A protective component, comprising a first arc-shaped protective plate, a second arc-shaped protective plate being slidably disposed on the first arc-shaped protective plate, and a protective window on the second arc-shaped protective plate;

[0007] A cleaning component is installed at one end of the first arc-shaped protective plate of the protective component. It is used to clean the inner wall of the protective window, and the cleaning component is connected to an external air pump through an air pipe.

[0008] Preferably, the cleaning assembly includes an inner tube installed on the first arc-shaped protective plate, the inner tube being connected to the air pump via an air pipe, an outer tube being rotatably sleeved on the outer side of the inner tube, and a cleaning component being provided on the outer side wall of the outer tube.

[0009] Preferably, the cleaning component includes an extension plate fixed to the outer wall of the outer tube, and a soft wiping block is installed at the end of the extension plate. The outer walls of the inner tube and the outer tube are respectively provided with an inner vertical through hole and an outer vertical through hole. There are two inner vertical through holes, which are symmetrically arranged. The extension plate is provided with a vertical slit that communicates with the outer vertical through hole.

[0010] Preferably, the upper and lower ends of the outer tube are both equipped with damped rotatable gears, and the inner sides of the upper and lower ends of the second arc-shaped protective plate are both fixed with arc-shaped racks. The gears and arc-shaped racks are located on the same horizontal line, and the torque required for the torsional displacement between the outer tube and the gear is greater than the torque required for the torsional displacement between the inner tube and the outer tube.

[0011] Preferably, the upper and lower edges of the first and second arc-shaped protective plates are both bent to form L-shaped bending structures, and the L-shaped bending structure of the second arc-shaped protective plate is slidably inserted into the L-shaped bending structure of the first arc-shaped protective plate.

[0012] Preferably, the L-shaped bending structures on the upper and lower sides of one end of the first arc-shaped protective plate extend laterally to form an extension portion, so as to allow the second arc-shaped protective plate to slide.

[0013] Preferably, a handle is installed at one end of the second arc-shaped protective plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model effectively isolates the processing area through a horizontally telescopic protective component, preventing chips, coolant splashes, and workpieces or tools from flying out. It solves the problem of the old-fashioned vertical lathe protective device being simple and having safety hazards. The protective component in this utility model can withstand the impact during the processing, further ensuring the safety of the operator.

[0016] 2. The cleaning component equipped with this utility model can automatically clean the inner wall of the protective window. It uses a dual cleaning method of soft wiping driven by the sliding motion of the second arc-shaped protective plate and compressed air cleaning to remove chips, coolant and oil stains, ensuring that the protective window remains transparent. At the same time, it improves the operator's ability to visually observe the processing process, thereby improving processing accuracy and safety.

[0017] 3. The cleaning component of this utility model does not require an additional motor drive. Instead, it uses the sliding motion of the protective plate to achieve the cleaning action through a gear and rack mechanism, which reduces energy consumption and meets the industrial requirements of energy conservation and environmental protection.

Detailed Implementation

[0024] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0025] This embodiment provides a technical solution: a vertical lathe protective device, such as... Figures 1 to 4 As shown, the system includes a mounting bracket 1, a protective assembly mounted on the mounting bracket 1, and a cleaning assembly 4. All components are controlled by an external control panel.

[0026] The number of mounting brackets 1 can be set to 1-3, depending on the size of the vertical lathe. The mounting brackets 1 can be set to a suitable height for the protective components to be installed on the lathe worktable. The mounting brackets 1 can also be set as lifting brackets to adjust the height of the protective components.

[0027] The vertical lathe has a circular worktable with a protective assembly on its outer side. The protective assembly includes a first arc-shaped protective plate 21 fixed to a mounting bracket 1. A second arc-shaped protective plate 23 is laterally slidably mounted on the first arc-shaped protective plate 21 to form a laterally telescopic protective structure. The upper and lower edges of both the first and second arc-shaped protective plates 21 and 23 are bent into L-shaped bends. The L-shaped bend of the second arc-shaped protective plate 23 is slidably inserted into the L-shaped bend of the first arc-shaped protective plate 21. The L-shaped bends on the upper and lower sides of one end of the first arc-shaped protective plate 21 extend laterally to form extensions 22, for the first arc-shaped protective plate 23 to extend laterally. The second arc-shaped protective plate 23 slides; the L-shaped bending structure of the second arc-shaped protective plate 23 is rotatably equipped with a pulley 27 to reduce the friction between the two and ensure that the second arc-shaped protective plate 23 is always stably supported and guided during the sliding process, avoiding sliding deviation or jamming; the second arc-shaped protective plate 23 has a protective window 24, the curvature of which is adapted to the curvature of the second arc-shaped protective plate 23. The protective window 24 allows the operator to directly observe the machining of the lathe and increases safety performance; the protective window 24 is made of transparent PC board or tempered glass, which can withstand the impact of splashed chips or coolant during the machining process.

[0028] The cleaning component 4 is an important functional part of the vertical lathe protective device. It is specifically used to clean the inner wall of the protective window 24 to prevent chips, coolant, or oil stains from adhering and affecting the observation effect. The cleaning component 4 is installed at one end of the first arc-shaped protective plate 21 of the protective component. It is used to clean the inner wall of the protective window 24. The cleaning component 4 is connected to the external air pump through an air pipe. The cleaning component 4 includes an inner tube 41 fixed to the first arc-shaped protective plate 21 by a fixing bracket. An outer tube 42 is rotatably sleeved on the outer side of the inner tube 41. The outer wall of the outer tube 42 is provided with cleaning parts. The number of cleaning parts can be set to 1-2.

[0029] The cleaning component includes an extension plate 43 fixed to the outer wall of the outer tube 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. The outer walls of the inner tube 41 and the outer tube 42 are respectively provided with an inner vertical through hole 45 and an outer vertical through hole 46. There are two inner vertical through holes 45, which are symmetrically arranged. The extension plate 43 is provided with a vertical slit 47 that communicates with the outer vertical through hole 46. When the outer tube 42 rotates to one side and the cleaning component contacts the inner wall of the protective window 24, the inner vertical through hole 45 on the corresponding side connects with the outer vertical through hole 46. When the angle of the outer tube 42 is in other positions, the inner vertical through hole 45 and the outer vertical through hole 46 are misaligned. A sealing strip is provided between the inner tube 41 and the outer tube 42. When the inner vertical through hole 45 and the outer vertical through hole 46 are misaligned, the inner tube 41 maintains good airtightness.

[0030] The upper and lower ends of the outer tube 42 are equipped with damped rotation (i.e., a certain force is required for rotation). The inner sides of the upper and lower ends of the second arc-shaped protective plate 23 are fixed with arc-shaped racks 410. The corresponding gears 48 and arc-shaped racks 410 are located on the same horizontal line, and the torque required for the torsional displacement between the outer tube 42 and the gears 48 is greater than the torque required for the torsional displacement between the inner tube 41 and the outer tube 42.

[0031] As the second arc-shaped protective plate 23 moves along the first arc-shaped protective plate 21, the gear 48 meshes with the arc-shaped rack 410, causing the outer tube 42 to rotate until the soft wiping block 44 of the cleaning component is pressed tightly against 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 move, although the gear 48 will also rotate, the reaction force generated will act on the inner wall of the second arc-shaped protective plate 23 and the protective window 24 to clean the inner wall of the second arc-shaped protective plate 23 and the protective window 24. At the same time, compressed air can be injected into the inner tube 41 through an external air pump. The compressed air will be sprayed out through the slit 47 to clean the inner wall of the second arc-shaped protective plate 23 and the protective window 24. That is, firstly, the surface chips and coolant are washed away by compressed air, and then the residual stains are wiped away by the soft wiping block 44. This dual cleaning method works together to ensure better cleaning effect of the protective window.

[0032] The cleaning component uses the sliding motion of the second arc-shaped protective plate 23 to drive the cleaning action, eliminating the need for an additional motor or power supply, thus reducing energy consumption and meeting the industrial requirements for energy conservation and environmental protection.

[0033] The cleaning component enables automatic cleaning of the inner wall of the protective window, maintaining its transparency and ensuring that operators can clearly observe the machining process of the vertical lathe (such as the workpiece cutting status and tool position), thus improving the visualization and safety of the machining process. Through the through-hole design of the inner and outer tubes and the vertical slits of the extension plate, the cleaning component achieves precise spraying of the cleaning fluid. The spraying direction is consistent with the wiping direction, enhancing the cleaning effect while avoiding waste of cleaning fluid and improving resource utilization.

[0034] The above are merely preferred embodiments of this utility model and are illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of this utility model, all of which will fall within the protection scope of this utility model.
