Description

Technical Field

[0001] This utility model relates to the field of machine tool protective door technology, and in particular to a machine tool protective structure. Background Technology

[0002] Machine tool protective structures, also known as personnel protection structures or machine tool protective doors, are an important part of machine tool design. They are mainly used to protect the personal safety of operators, prevent chips and coolant from splashing, and also reduce noise and dust pollution.

[0003] When the observation window of an existing machine tool protective structure is damaged and needs to be replaced, the entire door needs to be disassembled from the machine tool before the observation window can be replaced. This is inefficient and increases the labor intensity of the replacement process. To address these issues, the inventor has proposed a machine tool protective structure. Utility Model Content

[0004] The purpose of this utility model is achieved through the following means: a machine tool protective structure, including a door, an observation window, and a replacement component. The upper end of the door is provided with an installation notch. The installation component includes a fixed frame and a positioning frame. The positioning frame is movably disposed at one end of the installation notch. Swing blocks are provided at the middle and both ends of the bottom surface of the positioning frame. A swing seat is provided at the position between the swing blocks on the lower bottom surface of the installation notch. The swing seat and the swing blocks are rotatably connected by a rotating shaft. An embedded groove matching the observation window is provided at the position of the positioning frame near the middle of the installation notch. The observation window is detachably disposed in the embedded groove. The fixed frame is fixedly disposed at the end of the installation notch away from the positioning frame. The wall surface of the fixed frame near the observation window is abutted against the edge of the side wall surface of the observation window. A locking plate is provided at the top of the positioning frame. The locking plate extends toward the top of the door. A locking position matching the locking plate is provided at the position of the top of the door near the locking plate. The locking position is connected to the installation notch. The locking plate and the locking position are connected by a detachable rotating pin.

[0005] In a further embodiment of the above description, the side wall of the fixed frame is flush with the wall of the door on the side away from the positioning frame, and a cover plate is glued to the wall of the door on the side away from the positioning frame near the fixed frame; the fixed frame is used to provide a limiting function for the observation window on the wall on the side away from the positioning frame.

[0006] In a further embodiment of the above description, the end of the rotating pin is provided with a locking block. The locking plate and the locking position are provided with an insertion hole that matches the pin and the locking block near the rotating pin. The end of the insertion hole away from the locking plate is provided with a rotating hole. The size and depth of the rotating hole are the same as the length of the locking block. The end of the rotating pin away from the locking block is provided with a torsion position. By rotating the torsion position, the locking block is aligned with the position on the insertion hole that matches the locking block, so that the rotating pin can be taken out of the insertion hole or inserted into the insertion hole.

[0007] In the above description, as a further embodiment, a first movable gap is provided between the top surface of the mounting notch and the top surface of the positioning frame, and a second movable gap is provided between the top surface of the locking position and the locking block; the first and second movable gaps provide a way to prevent the positioning frame and the locking block from being unable to fold when they are folded around the rotation axis due to the top of the positioning frame and the top of the locking block being restricted.

[0008] In a further embodiment of the above description, mounting grooves are provided on both sides of the mounting notch, and the mounting grooves are connected to the mounting notch. A pneumatic rod is installed in the mounting groove, with the push rod of the pneumatic rod facing the lower end of the door. Connecting rods are provided at both ends of the positioning frame, and the push rod of the pneumatic rod is movably connected to the connecting rod. The end of the pneumatic rod away from the connecting rod is movably hinged to the top surface of the mounting groove. Controllable extension and contraction, buffer positioning, and self-locking support are achieved through the internal air pressure and damping characteristics of the pneumatic rod. When unfolded, the nitrogen gas inside the pneumatic rod expands, providing thrust to help the positioning frame smoothly unfold from the retracted state to the horizontal position, which is labor-saving and uniform.

[0009] In a further embodiment of the above description, a storage frame is provided in the middle of the wall surface of the door body near the positioning frame. A handle is provided on both sides of the storage frame. The top surface of the handle and the storage frame are in contact with the lower surface formed by folding the side wall surface of the positioning frame away from the door body by 90° through a rotating shaft. The top surface of the storage frame and the handle are used to limit the positioning frame while also supporting it.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: by using a swing block and a swing seat to swing the lower end of the positioning frame to the bottom surface of the installation notch, and at the same time, a locking plate and a rotating pin are provided at the top of the positioning frame for limiting the position, when the observation window needs to be replaced, it is not necessary to disassemble the entire door. Simply unlock the positioning frame by rotating the pin, fold the positioning frame through the connection between the swing block and the swing seat, take out the cracked observation window from the embedded groove, put the new observation window into the embedded groove, and finally fold the positioning frame back towards the direction of the installation notch, and finally lock it with the rotating pin. The installation process does not require disassembling the entire door, which improves installation efficiency and reduces labor intensity. Attached Figure Description

[0015] The end of the pin of the rotating pin 12 is provided with a locking block 14. The locking plate 10 and the locking position 11 are provided with an insertion hole 15 that matches the pin and the locking block 14 near the rotating pin 12. The end of the insertion hole 15 away from the locking plate 10 is provided with a rotating hole 16. The size and depth of the rotating hole 16 are the same as the length of the locking block 14. The end of the rotating pin 12 away from the locking block 14 is provided with a torsion position 17.

[0016] A first movable gap 18 is provided between the top surface of the installation notch 5 and the top surface of the positioning frame 4, and a second movable gap 19 is provided between the top surface of the locking position 11 and the locking block.

[0017] Both sides of the installation notch 5 are provided with installation grooves 20, which are connected to the installation notch 5. A pneumatic rod 21 is provided in the installation groove 20. The push rod of the pneumatic rod 21 is set towards the lower end of the door body 1. Both ends of the positioning frame 4 are provided with connecting rods 22. The push rod of the pneumatic rod 21 is movably connected to the connecting rod 22. The end of the pneumatic rod 21 away from the connecting rod 22 is movably hinged to the top surface of the installation groove 20.

[0018] A storage frame 23 is provided in the middle of the wall surface of the door body 1 near the positioning frame 4. A handle 24 is provided on both sides of the storage frame 23. The upper surface of the handle 24 and the storage frame 23 are in contact with the lower surface formed by the side wall surface of the positioning frame 4 away from the door body 1 after being folded 90° by the rotating shaft 8.

[0019] The working process of this utility model: 1) Unlocking: When the broken observation window 2 needs to be replaced, rotate the torsion position 17 to drive the locking block 14 on the pin to rotate. When the locking block 14 on the pin is rotated to the position corresponding to the insertion hole 15, the locking relationship between the locking plate 10 and the locking position 11 can be unlocked. 2) Flip out the positioning frame 4: Fold the positioning frame 4 and the locking plate 10 away from the door 1 via the rotating shaft 8. After folding, the inside of the positioning frame 4 away from the door 1 contacts the top surface of the storage frame 23 and the handle 24. While the positioning frame 4 is folding, the push rod of the pneumatic rod 21 is pulled out away from the door 1 via the connecting rod 22. At the same time, the lower end of the pneumatic rod 21 is tilted away from the door 1, i.e., the folding direction of the positioning frame 4. When the pneumatic rod 21 is tilted, it loses the limiting effect of the bottom surface of the mounting groove 20. The internal nitrogen expands and provides thrust to help the positioning frame 4 smoothly unfold from the folded state to the horizontal position, which is labor-saving and uniform. 3) Replace the observation window 2: Remove the damaged observation window 2 from the embedded groove 9, put the complete observation window 2 back into the embedded groove 9, and finally push the positioning frame 4 upward to fold the positioning frame 4 towards the door body 1. After folding it back to its original position, insert the rotating pin 12 into the insertion hole 15, and finally rotate it so that the locking block 14 is misaligned with the insertion hole 15.
