Description

Technical Field

[0001] This invention relates to a moving mechanism for a telescopic protective cover, and more particularly to a canopy protective cover opening and closing linkage device. Background Technology

[0002] The canopy of a typical machining center often needs to suspend workpieces in and out of the machine, so in addition to its basic retractable cover function, it may also need to be opened over a large area. However, the retractable cover assembly usually only has one fixed end and one movable end. The movable end is connected to a central moving frame and can move with it, while the fixed end of the retractable cover assembly is mostly stationary. Therefore, when it is necessary to move the fixed end to create a large opening, there are usually several methods.

[0003] The first and simplest method is to manually push the fixed end open. The other method is to add an additional power mechanism to the fixed end, using this external power device to move and open it.

[0004] Another method involves adding two sets of electromagnets to the fixed end of the telescopic cover. By controlling the conduction and deconduction of the two sets of electromagnets, the movement or stillness of the fixed end of the telescopic cover can be controlled. For example, this method is disclosed in CN113245897B, "A protective cover suction device and scheme for a five-axis machining center". However, these methods are inconvenient and complicated. Summary of the Invention

[0005] The main objective of this invention is to provide a simple and easy-to-use ceiling cover opening and closing linkage device that does not require additional power or control source.

[0006] To achieve the aforementioned main objectives, the canopy cover opening and closing linkage device of the present invention comprises: a telescopic cover assembly mounted on a track of a central machining center, the telescopic cover assembly comprising multiple cover plates and a connecting piece, each cover plate having a top surface, and the cover plates being interconnected via the connecting piece; the telescopic cover assembly having a movable end and a fixed end, the movable end being connected to a movable frame of the central machining center and movable with the movable frame; an extension arm disposed on the movable frame, the extension arm having a protruding end protruding toward the fixed end of the telescopic cover assembly, and a pivotally mounted swingable locking plate at the protruding end of the extension arm; and a baffle disposed on the last cover plate at the fixed end of the telescopic cover assembly, the baffle protruding upward from the cover plate by a certain height, the locking plate being able to abut against the baffle to push the last cover plate to move.

[0007] With the above structure, the extension arm of the canopy cover opening and closing linkage device of the present invention can use the card plate to abut against the baffle, so that when the moving frame moves, it is linked to the last piece of the canopy cover plate at the fixed end of the telescopic cover assembly through the extension arm and the card plate, thereby driving the entire telescopic cover assembly to move and achieve the purpose of opening a large area.

[0008] Preferably, the card plate is in a drooping state under normal conditions, so that the card plate extends from the protruding end toward the top surface of the cover plate.

[0009] Preferably, the height of the baffle extending upward from the cover plate is greater than the distance between the lowest edge of the baffle plate and the top surface of the cover plate.

[0010] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Attached Figure Description

[0030] The applicant hereby clarifies that, in this specification, including the embodiments described below and the claims, all directional terms refer to the directions shown in the drawings. Secondly, in the embodiments and drawings described below, the same element reference numerals represent the same or similar elements or their structural features, and the directions referred to in the specification are for illustrative purposes only and are not intended to be limiting.

[0031] Please see Figures 1-4 As shown, the ceiling cover opening and closing linkage device of the present invention includes:

[0032] A telescopic protective cover assembly 10 is installed on a pair of parallel rails 1 of a machining center. The machining center referred to in this invention is not limited to any specific model or type; any machining center requiring a canopy cover can be used with this structure. The examples shown in the drawings are for illustrative purposes only and are not intended to limit the scope of this invention. The telescopic protective cover assembly 10 includes multiple protective cover plates 11 and a connecting piece 12. Each protective cover plate has a top surface 13, and the protective cover plates 11 are interconnected via the connecting piece 12. Each protective cover plate 11 has its two ends spanning the pair of parallel rails 1 of the machining center. The telescopic shield assembly 10 has a movable end 14 and a fixed end 15. The movable end 14 is connected to a movable frame 2 of the central machining center and can move with the movable frame 2 so that the telescopic shield assembly 10 can extend and retract. The spindle head of a general machining center is operated and moved in conjunction with a movable frame. Therefore, this application uses the movable frame for description. Since the structure and shape of the central machining center are not the focus of this application, the central machining center will not be described in detail here.

[0033] An extension arm 20 is mounted on the movable frame 2. The extension arm 20 has a protruding end 21 that protrudes towards the fixed end 15 of the telescopic protective cover assembly. The length of the protrusion after the telescopic protective cover assembly 10 is retracted is the distance from the movable frame 2 to the fixed end 15 to the last protective cover plate 11. A swingable locking plate 22 is pivotally mounted on the protruding end 21 of the extension arm. The locking plate 22 has a notch 23, which is located on the side of the locking plate 22 facing the fixed end 15 of the telescopic protective cover assembly. The locking plate 22 is in a drooping state in the normal state, so the locking plate 22 extends from the protruding end 21 towards the top surface 13 of the protective cover plate.

[0034] A baffle 30 is provided on the last piece of the protective plate 11 at the fixed end of the telescopic protective cover assembly 10. The baffle 30 protrudes upward from the protective plate 11 by a height that is less than or equal to the distance between the protruding end 21 of the extension arm and the top surface 13 of the protective plate, but greater than the distance between the lowermost edge of the clamping plate 22 and the top surface 13 of the protective plate.

[0035] Based on the above structure, this invention is used by mounting it on a track on a central machining center. During normal operation, the movable end of the telescopic shield assembly 10 is connected to the movable frame 2 of the central machining center, allowing the telescopic shield assembly 10 to extend or retract as the movable frame 2 moves. At this time, the extension arm 20 moves with the movable frame 2, and the protruding end 21 approaches or passes through the baffle 30. Figure 3 or Figure 4 As shown. When the protruding end 21 approaches or passes the baffle, the locking plate 22 will be in a natural drooping state and will not be in contact with or connected to the baffle 30. Therefore, the extension arm 20 will not be connected to the baffle 30. Thus, the fixed end 15 of the telescopic shield assembly will not be affected by the movement of the extension arm 20.

[0036] When the fixed end 15 of the telescopic shield assembly needs to be moved for a large-area opening, the moving frame 2 can be moved to a position where the extension arm 20 slightly passes through the baffle 30, and the protruding end 21 slightly passes through the baffle 30. However, due to its length, the clamping plate 22 is not long enough to pass through the baffle 30, so the clamping plate 22 will be in a downward-sloping state. Figure 4 and Figure 5 As shown. At this time, the notch 23 of the locking plate will abut against the upper edge of the baffle 30. In this state, when the moving frame 2 moves back, that is, away from the fixed end 15 of the telescopic protective cover assembly, the locking plate 22 will push the baffle 30 in the opposite direction, thereby moving the last protective cover plate 11, so as to achieve the purpose of moving the entire telescopic protective cover assembly 10 to open a large area. When the telescopic protective cover assembly 10 needs to return to its original position, the moving frame 2 only needs to move towards the fixed end 15 of the telescopic protective cover assembly to push the entire telescopic protective cover assembly 10 back to its original position.

[0037] In other words, the telescopic protective cover assembly in this invention does not require an additional power unit. The user only needs to control the moving distance of the moving frame through the program settings on the central machining table. The purpose of whether to activate the telescopic protective cover assembly to open a large area can be achieved by whether the extension arm, the clamping plate and the baffle establish a connection relationship.

[0038] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the claims of the present invention.
