Description

Technical Field

[0001] This utility model relates to the field of machining centers, specifically a protective device for machining centers. Background Technology

[0002] A machining center is a high-precision, high-efficiency automated machine tool mainly used for machining operations such as milling, drilling, tapping, and turning. It is controlled by a CNC system and can automate various machining processes. It is often used in large-scale production, especially for machining complex parts. When machining in a machining center, protective devices are required to prevent flying chips and metal fragments from injuring operators or polluting the working environment.

[0003] For example, a Chinese patent discloses a protective device for a machining center (authorization announcement number CN214869091U). This patented technology includes a machining center body, a protective door, and a column. The machining center body has a protective door inside and a column on top. The protective door has an observation window. A support block is located inside the machining center body, and a first lead screw and a second lead screw are located inside the support block. A first connecting rod is rotatably connected to the top of the first mounting block via a first pin. A second mounting block is fixedly installed at the bottom of the protective door, and the second mounting block is rotatably connected to the end of the first connecting rod away from the first mounting block via a second pin. The column has first grooves on both sides inside and slots on both sides of the column. This machining center protective device can isolate noise generated by the machining center without interfering with its operation. The self-locking structure can lock the protective door to prevent accidental opening.

[0004] However, most existing machining centers use lead screws to move the protective doors. Since the lead screws are exposed to the elements, they are susceptible to dust, which can affect their normal transmission and thus the protective function. For example, the aforementioned comparative document uses lead screw transmission. In practical applications, when using lead screw transmission to open and close the protective doors, the exposed lead screw becomes contaminated, affecting the transmission and consequently the opening and closing of the protective doors. Therefore, those skilled in the art have provided protective devices for machining centers to solve the problems mentioned in the background art. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 In this embodiment of the utility model, a machining center body 1 is included. A fixing plate 2 is installed at the front end face of the machining center body 1. A cylinder 3 is installed on one side of the fixing plate 2, and a guide rod 21 is symmetrically arranged on the other side of the fixing plate 2. A movable frame 4 is slidably installed on the outside of the guide rod 21. A protective plate 5 is slidably installed inside the movable frame 4. A magnetic block 42 is also provided inside the movable frame 4, and a positioning pin 43 is symmetrically arranged on the inner side of the movable frame 4.

[0022] In this embodiment: the operation of the cylinder 3 causes the moving frame 4 to move outside the guide rod 21, thereby moving the protective plate 5 to open and close the machining center body 1, so as to maintain the interior of the machining center body 1.

[0023] Please refer to this carefully. Figure 2 and Figure 4 As shown, there are two positioning pins 43 on the inner side of the movable frame 4. One side of the protective plate 5 is provided with a positioning hole 52 that engages with the positioning pins 43. This arrangement allows the positioning pins 43 to be embedded into the positioning hole 52, thus achieving the purpose of positioning and installing the protective plate 5 into the interior of the movable frame 4.

[0024] Please refer to this carefully. Figure 2 and Figure 4As shown, the front surface of the protective plate 5 is provided with a handle groove 53, and the inner surface of the movable frame 4 is symmetrically provided with guide rails 41. The upper and rear surfaces of the protective plate 5 are provided with guide grooves 51 that slide against the guide rails 41. This arrangement utilizes the guide rails 41 to guide the movement within the guide grooves 51, thereby enabling the protective plate 5 to be guided and moved.

[0025] Please refer to this carefully. Figure 2 As shown, the magnetic block 42 is rectangular inside the movable frame 4, and the magnetic block 42 and the protective plate 5 attract each other. This arrangement utilizes the mutual attraction between the magnetic block 42 and the movable frame 4 to ensure the stability of the installation of the protective plate 5.

[0026] Please refer to this carefully. Figure 3 As shown, there are two guide rods 21 symmetrically arranged on one side of the fixed plate 2. The movable frame 4 is arranged in a "U" shape outside the guide rods 21. The guide rods 21 can guide the movable frame 4 when it moves, so as to ensure the stability of the movable frame 4.

[0027] Please refer to this carefully. Figure 3 As shown, the fixed end of the cylinder 3 is installed on one side of the fixed plate 2, and the telescopic end of the cylinder 3 is connected to the middle position of one side of the moving frame 4. This arrangement uses the operation of the cylinder 3 to make the moving frame 4 move outside the two guide rods 21, thereby adjusting the position of the protective plate 5 to open and close the main body 1 of the machining center.

[0028] The working principle of this utility model is as follows: When the protective device for the machining center protects the main body 1 of the machining center, the cylinder 3 on one side of the fixed plate 2 is activated, which causes the moving frame 4 to move outside the two guide rods 21. During its movement, the position of the protective plate 5 inside the moving frame 4 can be adjusted, thus sealing the operating port of the machining center main body 1 to achieve the purpose of protection. When it is necessary to disassemble and replace the protective plate 5, the finger is placed inside the handle groove 53 and moved to one side. During the movement, the positioning pin 43 will move out from the inside of the positioning hole 52. At the same time, the guide rail 41 guides the movement inside the guide groove 51, thus allowing the protective plate 5 to be disassembled and replaced. After replacement, the protective plate 5 only needs to be slid into the moving frame 4 and positioned by the positioning pin 43. At the same time, the magnetic block 42 is used to attract and fix it, thus achieving the purpose of protecting the main body 1 of the machining center. It has good practicality.

[0029] All electrical devices used in this invention are existing and known, and are connected to an external main controller and power supply. The main controller can be a conventional and known device such as a computer, and can be purchased and used directly on the market. Its structure, circuit and control principle are all existing and known technologies. Therefore, the structure, circuit and control principle of the device are not described in detail here.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
