Description

Technical Field

[0001] This utility model relates to the technical field of machine tool protective devices, and in particular to an opening and closing device for a machine tool canopy. Background Technology

[0002] During CNC machine tool processing, high-speed cutting generates a large amount of aluminum chips, cutting fluid splashes, and water mist, polluting the workshop environment and affecting equipment lifespan. Traditional solutions include fixed protective covers or manually opening and closing canopies, but these have the following problems:

[0003] Fixed protective covers: cannot meet the needs of workpiece hoisting and affect crane operation;

[0004] Manually operated canopy: Low efficiency, increases labor intensity for workers;

[0005] Existing automatic opening and closing mechanisms are complex in structure, costly, and lack reliability.

[0006] Therefore, it is necessary to design an opening and closing device for the machine tool canopy to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing an opening and closing device for a machine tool canopy.

[0008] The technical solution of this utility model is: an opening and closing device for a machine tool canopy, including a crossbeam, a canopy assembly, a rotating mechanism, a proximity switch system, and a control system; the crossbeam is movably arranged along the X-axis of the machine tool; one end of the canopy assembly is fixed to a sheet metal part at the front end of the crossbeam, and the other end is connected to the rotating mechanism through a canopy fixing frame; the rotating mechanism includes a front door-side rotating cylinder and a rear door-side rotating cylinder, which are respectively connected to the canopy fixing frame in a releasable manner through a hook machining part; the proximity switch system is used to detect the position of the crossbeam and trigger the action of the front door-side rotating cylinder or the rear door-side rotating cylinder; the control system controls the opening and closing of the solenoid valve of the front door-side rotating cylinder or the rear door-side rotating cylinder according to the proximity switch signal, so as to realize the automatic opening and closing of the canopy.

[0009] The hook machining parts of the front door side rotary cylinder and the rear side rotary cylinder are both L-shaped plates, and their rotation axis is orthogonally arranged with the movement trajectory of the canopy fixing frame.

[0010] The proximity switch system includes: a front door side proximity switch and a corresponding sensing plate for detecting the forward movement limit position of the crossbeam, and a rear side proximity switch for detecting the position of the canopy fixing bracket when it returns to its original position.

[0011] The control system includes a delay module that, after receiving a proximity switch signal, delays for two seconds to trigger the release action of the front door side rotary cylinder or the rear door rotary cylinder.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects: This utility model realizes unmanned operation of the canopy by linking a rotary cylinder with a proximity switch, enabling rapid and automatic opening and closing; at the same time, the movement of the crossbeam and the coordinated action of the cylinder ensure that the canopy completely avoids the crane chain when it is opened, effectively preventing interference; in addition, the use of standard cylinders and sheet metal structures reduces manufacturing costs; moreover, the canopy fully covers the worktable, effectively blocking the splashing of cutting fluid and aluminum chips.

[0019] (Example 1)

[0020] See Figures 1 to 3 This embodiment of a machine tool canopy opening and closing device includes a crossbeam 1, a canopy assembly 2, a rotating mechanism 3, a proximity switch system 4, and a control system. The crossbeam 1 is movably arranged along the X-axis of the machine tool. One end of the canopy assembly 2 is fixed to the front sheet metal part of the crossbeam 1, and the other end is connected to the rotating mechanism 3 through a canopy fixing frame 5. The rotating mechanism 3 includes a front door side rotating cylinder 3-1 and a rear side rotating cylinder 3-2, which are respectively connected to the canopy fixing frame 5 through a hook machining part 3-3. The proximity switch system 4 is used to detect the position of the crossbeam 1 and trigger the front door side rotating cylinder 3-1 or the rear side rotating cylinder 3-2 to operate. The control system controls the opening and closing of the solenoid valves of the front door side rotating cylinder 3-1 or the rear side rotating cylinder 3-2 according to the proximity switch signal, thereby realizing the automatic opening and closing of the canopy.

[0021] Furthermore, the hook machining parts 3-3 of the front door side rotary cylinder 3-1 and the rear side rotary cylinder 3-2 are both L-shaped plates, and their rotation axis is orthogonally arranged with the movement trajectory of the canopy fixing frame 5.

[0022] Furthermore, the proximity switch system 4 includes: a front door side proximity switch 4-1 and a corresponding sensing plate 4-2 for detecting the forward movement limit position of the crossbeam 1, and a rear side proximity switch 4-3 for detecting the position of the canopy fixing frame 5 when it returns to its original position.

[0023] Furthermore, the control system includes a delay module that, after receiving a proximity switch signal, delays for two seconds to trigger the release action of the front door side rotary cylinder 3-1 or the rear door side rotary cylinder 3-2.

[0024] The working process of this embodiment:

[0025] When a worker needs to lift a workpiece onto the machine tool's internal worktable, the canopy needs to be opened to avoid interference between the canopy and the crane chain. At this time, the crossbeam moves towards the door along the X-axis, and the canopy compresses accordingly. When proximity switch 4-1 senses proximity switch plate 4-2, the program senses that the rear rotary cylinder 3-2 has reached the appropriate position. The program sends a command to the solenoid valve, and the L-plate machining part installed on the rear rotary cylinder 3-2 hooks onto the canopy fixing frame 5. At this time, the solenoid valve of the front door rotary cylinder 3-1, after a 2-second delay in the program's M code, sends a signal instructing the solenoid valve of the front door rotary cylinder 3-1 to raise, releasing the canopy fixing frame 5. Because the rear rotary cylinder 3-2 is now hooked onto the canopy fixing frame 5, the crossbeam moves away from the front door along the X-axis, opening the space above the worktable. This allows workers to automatically load and unload workpieces using the crane.

[0026] When the worker completes the workpiece clamping, the canopy is compressed, and the crossbeam moves along the X-axis towards the entrance, pushing the canopy. During the movement, the canopy fixing frame 5 senses the rear proximity switch 4-3, indicating that the front door side rotary cylinder 3-1 can tilt down and hook the canopy fixing frame 5. At this time, the solenoid valve of the rear rotary cylinder 3-2, after a 2-second delay in the program M code, sends a signal to the solenoid valve of the rear rotary cylinder 3-2, causing the rear rotary cylinder 3-2 to lift up and release the canopy fixing frame 5. Since the front door side rotary cylinder 3-1 is now hooked on the canopy fixing frame 5, the crossbeam moves away from the front door along the X-axis, thus the canopy blocks the space above the worktable, the machine door closes, and the entire machine is processed.

[0027] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
