Description

Technical Field

[0001] This utility model relates to a retractable operating guardrail for a vertical machining center, belonging to the technical field of vertical machining centers. 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 shells. Vertical machining centers can perform milling, boring, drilling, tapping, and thread cutting operations. After the workpiece is clamped once on the machining center, the digital control system can control the machine tool to automatically select and change tools according to different operations, automatically change the spindle speed, feed rate, and tool movement trajectory relative to the workpiece, and other auxiliary functions to sequentially complete multiple operations on several surfaces of the workpiece. It also has multiple tool changing or tool selection functions, resulting in high production efficiency. Because gray cast iron has advantages such as high strength and good wear resistance, it is often used in the manufacture of high-stress castings such as the bed, guide rails, slides, rams, and columns of existing CNC machine tools.

[0003] Chinese Patent Publication No. (CN 219005241 U) discloses a vertical machining center, comprising a bed, column, saddle, ram, worktable, and support, all cast from mineral cementitious materials. The bed is equipped with a worktable drive device for driving the worktable to move along the Y-axis. The column is a symmetrical gantry structure, consisting of a left gantry column, a right gantry column, and a gantry beam. The gantry beam is equipped with a saddle drive device for driving the saddle to move along the X-axis. The saddle is equipped with a ram drive device. The ram houses a tool spindle and a spindle motor capable of driving the tool spindle. This utility model discloses a vertical machining center that reduces the impact of heat sources on machine tool temperature, reduces vibration of machine tool components, and minimizes thermal deformation of components during operation, enabling the machine tool to maintain stable geometric accuracy, motion accuracy, positioning accuracy, and repeatability during long-term operation. However, machining centers lack protective barriers during operation. During machining, the high-speed rotating cutting tools generate a large amount of hot, sharp metal or non-metal chips. These chips fly at extremely high speeds in all directions, like bullets. Without barriers, operators or nearby personnel are highly susceptible to being hit, resulting in severe cuts, burns, penetrating wounds, or eye injuries.

[0004] Therefore, a retractable operating guardrail for vertical machining centers is proposed. Utility Model Content

The front side of the connecting plate 102 is fixedly connected to the rear side of the machining center body 101, the front side of the double-headed cylinder 103 is fixedly connected to the rear side of the connecting plate 102, and the inner side of the extension plate 104 is movably connected to the interior of the connecting plate 102. A sliding groove 105 is provided inside the connecting plate 102. The inner side of the expansion plate 104 is movably connected to the inside of the sliding groove 105. An extension plate 106 is fixedly connected to the rear side of the expansion plate 104. The output end of the double-headed cylinder 103 is fixedly connected to the inner side of the extension plate 106. A moving groove 107 is provided at the bottom of the expansion plate 104. A moving wheel 108 is movably connected to the inside of the moving groove 107 through a rotating shaft. A buzzer 109 is fixedly connected to the top of the expansion plate 104. A warning light 110 is fixedly connected to the rear side of the buzzer 109. The buzzer 109 and the warning light 110 are electrically connected.

[0023] When the extension board 104 is unfolded by the telescopic assembly, the double-headed cylinder 103 extends horizontally to the outside at the same time. The telescopic cylinder pushes the connecting plate 102 to move outward, and the connecting plate 102 drives the extension board 104 to unfold outward. Through the sliding groove 105, the extension board 104 moves according to the movement trajectory provided by the sliding groove 105 when it is unfolded. Through the moving wheel 108, the extension board 104 can move more smoothly and improve the unfolding efficiency. Through the buzzer 109 and the warning light 110, the surrounding personnel are constantly alerted when the extension board 104 is moved to prevent collisions that may cause injury.

[0024] Example 2 like Figure 1 , Figure 4 , Figure 6 and Figure 7 As shown, in one embodiment, the closing assembly includes a front movable door 201, a rear movable door 202, a connecting block 203, and a positioning block 204. The outer sides of both the front and rear movable doors 201 and 202 are movably connected to the interior of the expansion plate 104 via pivots. The rear side of the connecting block 203 is fixedly connected to the front side of the front movable door 201, and the rear side of the positioning block 204 is fixedly connected to the front side of the rear movable door 202. The right side of the connecting block 203 corresponds to the left side of the positioning block 204. The rear side of the front movable door 201 contacts the front side of the rear movable door 202. The positioning block 204... The interior of the 4 has a cavity 205, and a pull rod 206 is movably connected inside the cavity 205. The right side of the pull rod 206 extends to the right side of the positioning block 204, and the left side of the pull rod 206 extends to the interior of the connecting block 203. A fixing plate 207 is fixedly connected to the surface of the pull rod 206. A compression spring 208 is fixedly connected to the right side of the fixing plate 207. The right side of the compression spring 208 is fixedly connected to the interior of the cavity 205, and the compression spring 208 is sleeved on the surface of the pull rod 206. A slot 209 is opened on the right side of the connecting block 203, and the left side of the pull rod 206 is movably connected to the interior of the slot 209.

[0025] The closing assembly opens the front movable door 201 and the rear movable door 202 when the operator uses the equipment, facilitating operation. The positioning block 204 and the connecting block 203 allow the pull rod 206 to be accurately inserted into the connecting block 203, improving the connection stability between the front movable door 201 and the rear movable door 202. The slot 209 allows the insert rod to be accurately inserted into the slot 209, ensuring a stable fixation between the front movable door 201 and the rear movable door 202.

[0026] When this utility model is in operation: First, the double-headed cylinder 103 is activated, and the telescopic cylinder pushes the connecting plate 102 to move outward. The connecting plate 102 drives the expansion plate 104 to unfold outward according to the moving trajectory provided by the sliding groove 105. During the unfolding, the moving wheel 108 at the bottom of the expansion plate 104 contacts the ground to improve the unfolding efficiency. After unfolding, the rear movable door 202 is rotated first, and then the front movable door 201 is rotated so that the rear side of the front movable door 201 contacts the front side of the rear movable door 202. The pull rod 206 is pulled, and the pull rod 206 moves to the right while compressing the compression spring 208. At this time, the connecting block 203 can be aligned with the positioning block 204. After alignment, the pull rod 206 is released, and the elastic force of the compression spring 208 causes the pull rod 206 to be inserted into the interior of the connecting block 203, thus fixing the front movable door 201 and the rear movable door 202.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
