Description

Technical Field

[0001] The present invention relates to a moving mechanism of a telescopic shield, and particularly to a ceiling shield opening and closing connection device.

Background Art

[0002] General Work The ceiling of a general machine often needs to be suspended to allow workpieces to enter and exit the machine. Therefore, in addition to the basic Expansion and contraction possible shielding function, it is also necessary to open a large area. However, usually, the Expansion and contraction possible set of shields has only one fixed end and one movable end. The movable end is connected to a movable frame at the center and can move together with the movable frame. Expansion and contraction The fixed end of the possible set of shields is usually fixed and does not move. Therefore, when it is necessary to move the fixed end to open a large area, usually there are several methods.

[0003] The first method is the simplest way of manually pushing and releasing the fixed end. Another way is to add an additional power mechanism to the fixed end and use the additional power mechanism to push and move the fixed end to open it.

[0004] Still another method is Expansion and contraction to add two sets of electromagnets to the fixed end of the possible shield and control the conduction or non-conduction of the two sets of electromagnets to Expansion and contraction control the movement or non-movement of the fixed end of the possible shield. For example, it is disclosed in the case of Patent Document 1 "A top protective suction device and solution for five-axis machining center". However, these methods are inconvenient and complex.

Modes for Carrying Out the Invention

[0012] The applicant hereby explains that, first, in the embodiments introduced below and in the claims in the patent application, the terms related to directions are based on the directions in the drawings. Second, in the embodiments introduced below and in the drawings, the same component numbers represent the same or similar components or structural features. The directions shown in the description are based on the directions in the drawings for ease of explanation, and are not limited thereto.

[0013] Referring to FIG. 1 to FIG. 4, the ceiling shield opening / closing connecting device of the present invention is Expansion and contraction The device includes a set of possible shields 10, extension arms 20, and baffles 30.

[0014] Expansion and contraction Set of 10 possible shields Work The machine is mounted on a pair of parallel rails 1. Work The machine has no specific model or type restrictions. It requires the use of a ceiling shield. Work The present structure can be applied to any machine. The examples in the drawings are only for convenience of explanation and are not intended to limit the present invention. Expansion and contraction The set of possible shields 10 comprises a plurality of shield plates 11 and connecting pieces 12. Each shield plate 11 has an upper surface 13. The shield plates 11 are connected to each other through connecting pieces 12. Each shield plate 11 has: Work It has its two ends spanning a pair of parallel rails 1 of the machine. Expansion and contraction The set of possible shields 10 has a movable end 14 and a fixed end 15. The movable end 14 is Work It is connected to the movable frame 2 of the machine and can move with the movable frame 2, so that Expansion and contraction The movable shield set 10 can be expanded and contracted. The spindle head of a typical processing machine moves in conjunction with the movable frame 2, so the present case will be described using the movable frame 2. Work The structure and shape of the machine are not the focus of this application. Work The machine will not be described in detail here.

[0015] The extension arm 20 is positioned on the movable frame 2. The extension arm 20 is Expansion and contraction The shield has a protruding end 21 protruding toward the fixed end 15 of the set of shields 10. The length of the protruding end 21 is Expansion and contraction Set of 10 possible shields Contraction After that, the fixed end 15 and The most fixed-end side The distance from the shield plate 11 to the extension arm 20 is a distance from the shield plate 11 to the extension arm 20. The extension arm 20 is provided with an engagement plate 22 that can swing at a protruding end 21. The engagement plate 22 is provided with a notch 23. The notch 23 is a distance from the shield plate 11 to the extension arm 20. Expansion and contraction 1, the shield plate 11 is disposed on the side opposite the fixed end 15 of the shield plate 11. The engagement plate 22 is in a pendulous state under normal circumstances so that the engagement plate 22 extends from the protruding end 21 toward the upper surface 13 of the shield plate 11.

[0016] Baffle 30 is Expansion and contraction At the fixed end 15 of the possible shield set 10 The most fixed-end side 2. The baffle 30 is positioned on the shield plate 11 of the shield plate 11. The baffle 30 projects upwardly from the shield plate 11 to a height that is less than the distance between the projecting ends 21 of the extension arms 20 and the upper surface 13 of the shield plate 11, but greater than the distance between the lowest edge of the engagement plate 22 and the upper surface 13 of the shield plate 11.

[0017] According to the above structure, the present invention, when used, Work It is also installed on rail 1 on the machine. During normal operation, Expansion and contraction The movable end 14 of the set of possible shields 10 is Work It is connected to the movable frame 2 of the machine and can move with the movable frame 2, so that Expansion and contractionThe set 10 of possible shields can be expanded or contracted. At this point, the extension arm 20 moves with the movable frame 2, and the protruding end 21 approaches or passes through the baffle 30 as shown in FIG. 3 or FIG. 4. When the protruding end 21 approaches or passes through the baffle 30, the engaging plate 22 is in a natural hanging state without contacting or connecting to the baffle 30. Therefore, since the extension arm 20 is not connected to the baffle 30, Expansion and contraction the fixed end 15 of the set 10 of possible shields is not affected by the movement of the extension arm 20.

[0018] To open a large area Expansion and contraction If it is desired to move the fixed end 15 of the set 10 of possible shields, the movable frame 2 can be moved to a position where the extension arm 20 slightly passes through the baffle 30. Therefore, the protruding end 21 slightly passes through the baffle 30. However, since the engaging plate 22 is not long enough to pass through the baffle 30, the engaging plate 22 hangs obliquely as shown in FIGS. 4 and 5. At this point, the notch 23 of the engaging plate 22 adheres to the upper edge of the baffle 30. In this state, when the movable frame 2 moves back, that is, Expansion and contraction when moving away from the fixed end 15 of the set 10 of possible shields, the engaging plate 22 pushes the baffle 30 in the reverse direction, The most fixed-end side and also drives the shield plate 11 to move, thereby Expansion and contraction achieving the purpose of moving the set 10 of possible shields as a whole to open a large area. Expansion and contraction If the set 10 of possible shields should return to its original position, the movable frame 2 Expansion and contraction moves in the direction of the fixed end 15 of the set 10 of possible shields, Expansion and contraction and only needs to push the entire set 10 of possible shields back to its original position.

[0019] That is, in the present invention Expansion and contraction the set of possible shields does not require the installation of an additional power device. The user WorkIt is only necessary to control the moving distance of the movable frame through the program settings on the machine, and then establish the connection relationship through any one of the stretching arm, the engaging plate and the baffle, and Expansion and contraction the purpose of releasing a set of possible shields over a wide area can be achieved.
