Description

Technical Field

[0001] This utility model belongs to the field of vertical machining centers, and specifically relates to an automatic top door structure for vertical machining centers. Background Technology

[0002] To improve production efficiency and ensure production safety, it is necessary to configure automated processing equipment with self-inspection functions to reduce safety hazards by minimizing manual operations. Existing machine tool sliding doors often use a front-opening and closing method, which is no longer sufficient to meet the high-efficiency automated processing requirements of vertical machining centers. Adopting an automatic top door combined with an automatic loading and unloading system can not only improve economy and operational convenience but also avoid the safety hazards associated with front-opening sliding doors, thus enhancing safety. However, existing automatic top doors still have the following problems: 1) Automatic top doors are usually made of sheet metal, and the collision of sheet metal during opening and closing can easily cause shaking and noise; 2) Sheet metal materials make the door heavy and slow in movement; 3) After long-term use, the sheet metal surface is prone to wear and tear, resulting in poor durability. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an automatic top door structure for vertical machining centers, which addresses the shortcomings of existing technologies. The structure adopts an innovative bellows-type automatic top door structure. The bellows has advantages such as fast and stable operation, low working noise, and safety and reliability, which can significantly improve the loading and unloading efficiency of vertical machining centers. At the same time, the bellows is lightweight and inexpensive, which can save costs.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an automatic top door structure for a vertical machining center, including a bellows, a guide rail, a cylinder, and a first limit switch. The bellows, guide rail, cylinder, and first limit switch are respectively installed on the top of the machine tool protective cover. A vertical sliding door is installed on the front side of the machine tool protective cover. A window is opened on the top of the machine tool protective cover. One side of the bellows is fixedly connected to the top of the machine tool protective cover, and the other side of the bellows is fixedly connected to the cylinder rod of the cylinder. The bellows is slidably connected to the guide rail, and the guide rail is arranged along the axial direction of the cylinder rod. A first sensing bracket adapted to the first limit switch is installed on the bellows. The bellows is used to extend and retract under the drive of the cylinder to realize the opening and closing of the window. The first limit switch is used to detect whether the bellows has extended and retracted to the correct position.

[0005] This invention employs an innovative accordion-style automatic top door structure. The accordion's extension and retraction are achieved through a cylinder drive. The linear reciprocating motion of the cylinder rod directly drives the accordion to open and close. During the accordion's extension and retraction, the first sensing bracket moves with the accordion, sending a signal to the machine tool control system in conjunction with a first limit switch, enabling precise control and control of the window's opening and closing. Compared to traditional automatic top doors, the accordion offers advantages such as fast and stable operation, low noise, and high safety and reliability. It significantly improves the loading and unloading efficiency of vertical machining centers. Furthermore, the accordion is lightweight and inexpensive, saving costs.

[0006] Preferably, a guide block is fixed to the top of the guide rail, the guide block being arranged along the length of the guide rail, and a slider is fixed to the bottom of the bellows, the slider being slidably connected to the guide block. The cooperation between the guide block and the slider ensures the linearity and stability of the bellows' telescopic movement, improves operational accuracy and reliability, and guarantees smooth and stable door opening.

[0007] Preferably, a vertical plate is fixedly connected to the side of the guide rail, the vertical plate being arranged along the length of the guide rail, and a notch being provided at the bottom of the bellows, with the top of the vertical plate located within the notch. The function of the vertical plate is to limit the movement of the bellows and prevent lateral displacement during its extension and retraction.

[0008] Preferably, the bottom of the guide rail is provided with a guide groove, and the top of the vertical sliding door is equipped with a roller. The roller is located within the guide groove and is slidably connected to the guide rail. The guide groove and the roller together enable the vertical sliding door to open and close smoothly and steadily, ensuring that the running trajectory of the vertical sliding door is accurate and reliable.

[0009] Preferably, a first folding plate is fixed to the top of the vertical sliding door, and the rollers are installed on the upper part of the first folding plate. A second folding plate is integrally formed at the bottom of the vertical plate, located below the first folding plate. The second folding plate and the first folding plate form a maze structure. This maze structure serves a protective function, preventing cutting fluid splashed during machine tool processing from exiting the machine tool protective cover.

[0010] Preferably, a connecting plate is fixed to the top of the machine tool protective cover, and one side of the bellows is fixedly connected to the connecting plate.

[0011] Preferably, a switch bracket is fixed to the top of the machine tool protective cover, and the first limit switch is mounted on the switch bracket.

[0012] Preferably, the guide rail is made of stainless steel, and there are two sets of guide rails. The two sets of guide rails are spaced apart on the top of the machine tool protective cover. The front and rear edges of the bellows are each slidably connected to one set of guide rails. A protective cover is provided on the outer side of the front edge of the bellows and the guide rail to which it is slidably connected. The protective cover can prevent the side edges of the guide rails and bellows from being exposed and has the effect of preventing cutting fluid from splashing out of the machine tool protective cover.

[0013] Preferably, there are two sets of bellows and two sets of cylinders, with the two sets of cylinders spaced apart on the top of the machine tool protective cover, and the cylinder rod of each set of cylinders is fixedly connected to one set of bellows.

[0014] Preferably, a second limit switch is installed on the inner side of the protective cover, and a second sensing bracket adapted to the second limit switch is installed on the top of the vertical sliding door. The second limit switch is used to detect whether the vertical sliding door is fully open or closed.

[0015] Compared with existing technologies, this utility model has the following advantages: This utility model adopts an innovative accordion-style automatic top door structure. The accordion's extension and retraction are achieved through a cylinder drive. The linear reciprocating motion of the cylinder rod directly drives the accordion to open and close. During the extension and retraction of the accordion, the first sensing bracket moves with the accordion, sending a signal to the machine tool control system in conjunction with the first limit switch, enabling precise control and control of the window's opening and closing. Compared with traditional automatic top doors, the accordion has advantages such as fast and stable operation, low operating noise, and high safety and reliability. It can significantly improve the loading and unloading efficiency of vertical machining centers. Furthermore, the accordion is lightweight and inexpensive, saving costs. Attached Figure Description
