Description

Technical Field

[0001] This utility model relates to the field of Z-axis protection technology, specifically a Z-axis protection device for a vertical machining center. Background Technology

[0002] A vertical machining center is a machining center whose spindle axis is perpendicular to the worktable. It is mainly suitable for machining complex parts such as plates, discs, molds, and small housings. Vertical machining centers can perform milling, boring, drilling, tapping, and thread cutting. While the column height of a vertical machining center is limited, restricting its machining range for box-shaped workpieces, it offers advantages such as convenient workpiece clamping and positioning; easy observation of the tool movement trajectory; and convenient program debugging, inspection, and measurement, allowing for timely problem detection and downtime for repair or modification. Compared to corresponding horizontal machining centers, vertical machining centers have a simpler structure, smaller footprint, lower price, and wider application range.

[0003] A search revealed an existing patent (publication number: CN207807260U) disclosing a Z-axis protective cover device for a vertical machining center. The device includes a column, a linear guide rail, a sliding part, a connecting plate, a protective cover, a bracket, and a connecting box. The linear guide rail is vertically mounted on the column. The sliding part is mounted on the linear guide rail and can slide up and down along it. A connecting plate is located at the bottom of the sliding part. The protective cover is mounted on the linear guide rail. An upper mounting plate and a lower mounting plate are respectively located at the top and bottom of the protective cover. The upper mounting plate is connected to the connecting plate. The connecting box is located at the bottom of the column, and the lower mounting plate is connected to the top of the connecting box. The bracket includes two opposing support columns and a platform. The platform is positioned between the support columns and at the bottom of the support columns. The support columns are connected to both ends of the protective cover. This invention can reduce the operating noise of the vertical machining center, meet the requirements of rapid Z-axis movement, and prevent lubricating oil contamination of the equipment.

[0004] It can only protect the linear guide below the sliding part, but it does not protect the top of the linear guide. Its protection is not comprehensive. In addition, there is no opening at the bottom of its connecting box. During processing, debris may fly out and enter above its protective cover and then accumulate inside the connecting box, making it difficult to clean later. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a Z-axis protection device for a vertical machining center, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a Z-axis protection device for a vertical machining center, including a cabinet, two linear guide rails fixed on the front surface of the cabinet, a movable part provided at the front of the cabinet, the rear end of the movable part being fixedly connected to the slider of the linear guide rail, a protective mechanism provided on the outer side of the linear guide rail, the protective mechanism including two fixing strips, and grooves provided on the opposite sides of the two fixing strips;

[0007] A steel wire is provided between the two fixing strips. The left and right sides of the steel wire are located inside the groove. Fixing frames are fixed above and below the fixing strips. A rotating rod is rotatably connected inside the fixing frame. Two through holes are opened on the side of the fixing frame near the fixing strip. The upper and lower ends of the steel wire pass through the through holes and are fixedly connected to the outer side wall of the rotating rod, respectively. The slider of the linear guide rail passes through the steel wire.

[0008] Preferably, a spring is fixed to the outer wall of the rotating rod, and the other end of the spring is fixedly connected to the inner wall of the fixed frame.

[0013] Beneficial effects

[0014] This utility model provides a Z-axis protection device for a vertical machining center. Compared with the prior art, it has the following advantages:

[0015] 1. The Z-axis protection device of this vertical machining center, by setting up a protection mechanism, the movement of the slider of the linear guide will move the reinforcing frame, and the reinforcing frame will move the steel wire. When the steel wire moves up and down, the spring will rotate the rotating rod to wind up the steel wire. In this way, the steel wire can protect the upper and lower parts of the linear guide without affecting the up and down movement of the slider of the linear guide.

[0016] 2. The Z-axis protection device of this vertical machining center has an anti-drop mechanism. The barbs are inserted into the inside of the steel wire. When the steel wire moves, the barbs will move. The movement of the barbs will cause the rotating ring to rotate. This will not affect the movement of the steel wire. The barbs restrict the left and right movement of the steel wire and can prevent the steel wire from falling out of the groove on the left and right sides. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6This utility model provides a technical solution: a Z-axis protection device for a vertical machining center, including a cabinet 1. Two linear guide rails 8 are fixed on the front surface of the cabinet 1. A movable part 4 is provided at the front of the cabinet 1. The rear end of the movable part 4 is fixedly connected to the slider of the linear guide rail 8. A protective mechanism 2 is provided on the outside of the linear guide rail 8. The protective mechanism 2 includes two fixing bars 3. Grooves 13 are provided on opposite sides of the two fixing bars 3. A steel wire 6 is provided between the two fixing bars 3. The left and right sides of the steel wire 6 are located inside the grooves 13. Fixing frames 5 are fixed above and below the fixing bars 3. Rotating rods 10 are rotatably connected inside the fixing frames 5. Two through holes 12 are provided on the side of the fixing frame 5 near the fixing bars 3. The upper and lower ends of the steel wire 6 are respectively... The linear guide rail 8 is fixedly connected to the outer wall of the through-hole 12 and the rotating rod 10. The slider passes through the steel wire 6, which protects the linear guide rail 8. A spring 19 is fixed to the outer wall of the rotating rod 10. The other end of the spring 19 is fixedly connected to the inner wall of the fixed frame 5, which can wind up the steel wire 6. Two baffles 11 are rotatably connected to the outer wall of the lower rotating rod 10. The outer wall of the baffle 11 is fixedly connected to the inner wall of the fixed frame 5, which can prevent debris from entering the interior of the lower spring 19. Multiple reinforcing frames 7 are fixed inside the steel wire 6. The slider of the linear guide rail 8 passes through the reinforcing frames 7. Two openings 9 are opened at the bottom of the lower fixed frame 5, which can allow debris that enters the interior of the lower fixed frame 5 to fall downward.

[0026] Furthermore, the fixing strip 3 is provided with multiple anti-detachment mechanisms 16 inside. The anti-detachment mechanism 16 includes a rotating ring 18. Multiple circular grooves 17 are opened inside the fixing strip 3. A fixing rod 15 is fixed inside the circular groove 17. The outer side wall of the fixing rod 15 is rotatably connected to the inner side wall of the rotating ring 18. Multiple spikes 14 are fixed on the outer side wall of the rotating ring 18, which can prevent the steel wire 6 from detaching from the groove 13.

[0027] During operation, the linear guide 8 is activated, and its slider moves. This movement of the slider moves the reinforcing frame 7, which in turn moves the steel wire 6. As the steel wire 6 moves up and down, the spring 19 rotates the lever 10 to wind up the steel wire 6. In this way, the steel wire 6 can protect both the upper and lower parts of the linear guide 8 without affecting the up-and-down movement of the slider. At the same time, the spike 14 is inserted into the steel wire 6. When the steel wire 6 moves, it causes the spike 14 to move, which in turn causes the rotating ring 18 to rotate. This does not affect the movement of the steel wire 6, but the spike 14 restricts the left and right movement of the steel wire 6 to prevent it from dislodging from the groove 13 on the left and right sides.
