Description

Technical Field

[0001] This utility model relates to the technical field of machining center accessories, and in particular to a machining center anti-sinking protective door. Background Technology

[0002] In the manufacturing industry, automated machining centers have become one of the mainstays of production and processing. To improve safety, machining centers are usually equipped with safety doors, which are mostly sliding doors to reduce the space they occupy.

[0003] Protective doors come in various structures, including straight and bent types. Taking a bent protective door as an example, the part with the viewing panel is a vertical straight panel, with the bottom of the panel bent towards the body. This shifts the center of gravity of the entire protective door, making it prone to jamming or sagging during use. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides a machining center anti-sinking protective door with a reasonable structure, which can effectively maintain the smoothness of the horizontal sliding of the protective door.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A machining center anti-sinking protective door includes a door frame, a door body slidably connected to the door frame, a linear bearing connecting the top of the door body to the door frame, a linear rail connecting the bottom of the door body to the door frame, and a counterweight reinforcing rib provided near the linear rail on the door body.

[0007] An auxiliary anti-deviation component is also provided between the top of the door and the door frame. The auxiliary anti-deviation component uses several elastic balls, which are rolled on both sides of the top of the door facing the machine tool and away from the machine tool.

[0008] As a further improvement to the above technical solution:

[0009] The top of the door frame is formed with a receiving part for accommodating the door body and linear bearings. The inner wall of the receiving part has a receiving groove facing the door body; elastic balls fall into the receiving groove.

[0010] The opening size of the receiving groove is smaller than the width of the groove inside.

[0011] In the initial state, the elastic ball is in contact with the door body and is in a non-deformable state.

[0012] The door is divided into an upper part and a lower part. The counterweight reinforcing rib is located in the lower part of the door and on the side of the door facing the machine tool.

[0013] The top width of the counterweight reinforcing rib is smaller than its bottom width.

[0014] The counterweight reinforcing ribs are arranged in an array on a single door body.

[0015] The door has a hollow interlayer, and the counterweight reinforcing ribs are located inside the hollow interlayer.

[0016] The counterweight reinforcing rib is a continuous structure and is built into the bottom of the hollow sandwich layer.

[0017] The beneficial effects of this utility model are as follows:

[0018] This utility model addresses the issue of easily tipped-over security doors, proposing an anti-sinking and anti-tipping structure for bending security doors. The main technical approach involves adding weight to the lower half of the door body, so that the center of gravity rests on the bottom linear rail, which has load-bearing and sliding functions. A linear bearing is used at the top of the door body as a lighter sliding component. Simultaneously, an elastic ball is installed at the top of the door frame as a protective structure to prevent tipping without affecting sliding.

[0019] When manually pushing or pulling a safety door, opening it inevitably involves applying pressure to the door, causing it to tend to tilt inwards. Conversely, manually pulling it closed involves applying an outward pulling force. These actions result in the door being subjected to inward or outward forces perpendicular to its structure. Since most safety doors are relatively lightweight, these forces can affect their stability.

[0020] In other words, besides the weight of the protective door itself and the shift in its center of gravity, the operator's actions in opening and closing the door also affect its stability. The elastic ball structure proposed in this application can effectively prevent this from happening. When the protective door is manually pushed or pulled, if the door tends to tilt forward or backward, it will be held in place by the elastic ball, which will assist in its return to its original position; the elastic ball will not increase the resistance to movement. When there is no external force, the counterweight reinforcement will stabilize the center of gravity of the protective door at the bottom rail, preventing it from sinking or tilting.

[0021] This application also proposes two methods for installing reinforcing ribs. The external longitudinal reinforcing ribs are easy to produce, while the internal transverse reinforcing ribs can reduce spatial interference to the workpiece, loading / unloading, or manual operation.

[0031] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0032] like Figures 1-6 As shown, the anti-sinking protective door of the machining center in this embodiment includes a door frame 1 and a door body 2 slidably connected to the door frame 1. A linear bearing 3 is connected between the top of the door body 2 and the door frame 1; a linear rail 4 is connected between the bottom of the door body 2 and the door frame 1; and a counterweight reinforcing rib 201 is provided on the door body 2 near the linear rail 4.

[0033] An auxiliary anti-deviation component is also provided between the top of the door body 2 and the door frame 1. The auxiliary anti-deviation component uses several elastic balls 5, which are rolled on both sides of the top of the door body 2 facing the machine tool and away from the machine tool.

[0034] The top of the door frame 1 is formed with a receiving part 101 for accommodating the door body 2 and the linear bearing 3. The inner wall of the receiving part 101 is provided with a receiving groove 102, which faces the door body 2. The elastic ball 5 falls into the receiving groove 102.

[0035] The opening size of the receiving groove 102 is smaller than the width of the groove inside.

[0036] In the initial state, the elastic ball 5 is in contact with the door body 2, and the elastic ball 5 is in a non-deformable state.

[0037] The door body 2 is divided into an upper part and a lower part. The counterweight reinforcing rib 201 is located in the lower part of the door body 2 and is located on the side of the door body 2 facing the machine tool.

[0038] The top width of the counterweight reinforcing rib 201 is smaller than its bottom width.

[0039] The counterweight reinforcing ribs 201 are arranged in an array on a single door body 2.

[0040] The door body 2 has a hollow interlayer, and the counterweight reinforcing rib 201 is located inside the hollow interlayer.

[0041] The counterweight reinforcing rib 201 is a continuous structure and is built into the bottom of the hollow interlayer.

[0042] The specific structure and working principle of this utility model are as follows:

[0043] This utility model addresses a protective door that bends towards the machine tool from the bottom. If a conventional linear bearing 3 is used directly on the top and bottom of the protective door, the torque at the linear bearing 3 will be affected due to the center of gravity, causing the protective door to tilt or sink around the linear bearing 3, posing a safety hazard.

[0044] like Figures 2-4 As shown, in order to address these technical issues, this application replaces the linear bearing 3 at the bottom of the door body 2 with a linear rail 4, retains the linear bearing 3 at the top of the door body 2, and adds reinforcing ribs to the lower half of the door body 2.

[0045] Linear rail 4 is used instead of linear bearing 3. The advantages of linear rail 4 are that it has a larger contact area and higher stability. When applied to the bottom of door body 2, it does not flip during sliding and can withstand greater torque.

[0046] Door body 2 offers two options: a single-layer structure and a double-layer hollow structure. For example... Figure 2 As shown, a single-layer structure door 2 has multiple counterweight reinforcing ribs 201 arrayed on the side facing the machine tool. In order to further lower the center of gravity, the counterweight reinforcing ribs 201 can be set to a structure that is narrow at the top and wide at the bottom, that is, the size of the counterweight reinforcing ribs 201 gradually increases from top to bottom.

[0047] If a door body 2 structure with a hollow space is adopted, the counterweight reinforcing rib 201 can be a single strip, built into the bottom of the door body 2, so that the center of gravity is lower.

[0048] The aforementioned structure can overcome the influence of the door's own weight. However, if an operator pushes or pulls the protective door, the operator's hand movements will exert an external force perpendicular to the door. For example, when pushing the protective door open, the hand inevitably applies a pressing force to the door, causing it to tend to tilt inward; when manually pulling the door closed, the hand applies an outward pulling force, causing it to tend to tilt outward. To further overcome these problems, in conjunction with reference to... Figure 6This application includes a receiving portion 101 formed at the top of the door frame 1. The receiving portion 101 has an n-shaped cross-section and covers the top of the door body 2. On each of the two opposing inner walls of the receiving portion 101, a receiving groove 102 is formed, and multiple elastic balls 5 are rolled within the receiving groove 102. The elastic balls 5 can be made of nylon, rubber, silicone, etc. The elastic balls 5 will not fall out of the groove and are positioned directly against the inner and outer side walls of the door body 2. When the door body 2 tends to tilt inward or outward, the elastic balls 5 abut against the door body 2 and undergo elastic deformation, preventing the door body 2 from tipping over and assisting in its return to its original position. When the door body 2 is not subjected to external force, the elastic balls 5 lightly adhere to the door body 2 without any other impact.

[0049] Therefore, the structure proposed in this application overcomes the problem of the eccentricity and easy tipping of irregularly shaped protective doors on the one hand, and optimizes the solution to the inward and outward tipping tendency that may occur when opening and closing the door on the other hand, effectively improving the stability of the door body 2.
