Description

Technical Field

[0001] This utility model belongs to the field of machine tool technology for mechanical cutting processing, and in particular relates to an electric automatic door. Background Technology

[0002] As an important branch of mechanical processing, machine tool manufacturing is undergoing profound changes in its production methods, driven by the rapid development of automation technology. With the large-scale introduction of industrial robotic arms and intelligent robots into production lines, the demand for automated supporting equipment in production systems is increasing daily. Among these, automatic machine tool doors, as key supporting devices, have become an indispensable component of modern intelligent manufacturing.

[0003] Depending on the driving method, automatic machine tool doors are mainly divided into two technical types: pneumatic doors use compressed air to drive cylinders as the power source, while electric doors rely on servo motors for power output. Compared with traditional pneumatic doors, electric doors exhibit significant advantages in technical performance, possessing a higher operating speed limit and achieving more accurate motion response speed and positioning precision. This high dynamic response characteristic and precise control capability make electric doors particularly suitable for automated machining scenarios requiring rapid cycles and precise positioning.

[0004] Under high-speed operation, the technical shortcomings of electric doors in terms of dynamic characteristics gradually become apparent. Because the servo system lacks the inherent gas compression buffering mechanism of pneumatic devices, coupled with its significantly increased operating speed, the combined effect of these two factors induces more pronounced mechanical vibration, resulting in more severe vibrations during door operation. For example... Figure 1 As shown, a traditional electric door includes a motor 100, a lead screw 200, a cantilever 300, and a door support 400. A slider 500 is threaded onto the lead screw. One end of the cantilever 300 is connected to the slider 500, and the other end of the cantilever 300 is equipped with a connector 600. The front end of the connector 600 is connected to the door support 400, which is rigidly connected to the front door of the machine tool. The working principle of this traditional electric door is as follows: The motor 100 drives the lead screw 200 to rotate. Based on screw transmission, the slider 500 moves linearly along the axis of the lead screw 200, thereby driving the cantilever 300 to move. Since the cantilever 300 and the door support 400 are connected by the connector 600, the movement of the cantilever 300 drives the movement of the door support 400. During the operation of this conventional electric gate, the cantilever 300 and the gate support 400 are connected by a connector 600, which is a rigid connection. Because the cantilever 300 is long, its overhanging end causes the cantilever to sag. When the electric gate is in use, the gate support 400 will be subjected to a component force that is different from the direction of movement, resulting in vibration. Utility Model Content

[0005] The purpose of this invention is to provide an electric automatic door to solve the problem of vibration caused by high-speed operation in existing electric doors.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] An electric automatic door includes an electric door drive, an electric door cantilever, and an electric door bracket. One end of the electric door cantilever is located at the output end of the electric door drive, and the other end of the electric door cantilever is provided with a robotic arm structure. The electric door drive is used to drive the electric door cantilever to move.

[0014] Furthermore, the cross-section of the connecting protrusion is rectangular.

[0015] Furthermore, a gap is left between the connecting protrusion and the connecting groove.

[0016] Furthermore, a protective layer is provided on the outer surface of the connecting protrusion.

[0017] Furthermore, the material of the first protective layer is an elastic material.

Detailed Implementation

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] like Figure 2As shown, an electric automatic door includes an electric door drive unit 1, an electric door cantilever 2, and an electric door bracket 3. One end of the electric door cantilever 2 is located at the output end of the electric door drive unit 1, and the other end of the electric door cantilever 2 is provided with a robotic arm structure 4. The electric door drive unit 1 is used to drive the electric door cantilever 2 to move.

[0030] The electric door support 3 is provided with a connecting protrusion 31, and the robotic arm structure 4 is provided with a connecting groove 41 to accommodate the connecting protrusion 31;

[0031] In this electric automatic door, the electric door drive component 1 is used to drive the movement of the electric door cantilever 2. The movement of the electric door cantilever 2 can drive the movement of the robotic arm structure 4. Since the electric door bracket 3 is provided with a connecting protrusion 31, and the robotic arm structure 4 is provided with a connecting groove 41 to accommodate the connecting protrusion 31, the movement of the robotic arm structure 4 can drive the movement of the electric door bracket 3. In actual installation, the electric door bracket 3 is rigidly installed on the front door of the machine tool. When the electric door bracket 3 moves, it will drive the front door of the machine tool to move.

[0032] In traditional electric automatic doors, the cantilever 300 and the door support 400 are connected by a connector 600. This connection is rigid, and because the cantilever 300 is relatively long, its overhanging end causes it to sag. During use, the door support 400 experiences a force in a direction opposite to the direction of movement, resulting in vibration. However, the electric automatic door provided by this invention features a robotic arm structure 4 on the cantilever 2, and this robotic arm structure 4 has a connecting groove 41 for accommodating the connecting protrusion 31. Therefore, it has the following advantages:

[0033] First, the traditional rigid connection is replaced by an embedded sliding fit of protrusions and grooves. This non-rigid connection method constructs a flexible linkage system with self-adjustment function, which effectively eliminates resonance.

[0034] Secondly, a three-dimensional self-correcting system is formed through the embedded sliding fit of protrusions and grooves, which automatically corrects the deviation of the motion trajectory through the sliding friction of the contact surface.

[0035] Third, the structural reliability of the electric automatic door is improved by adopting the protrusion-groove embedded sliding fit structure, which ensures both transmission rigidity and elastic deformation capability.

[0036] Fourth, the optimization of the assembly process can significantly reduce the installation accuracy requirements;

[0037] Fifth, maintenance costs are reduced. Due to the use of the protrusion-groove embedded sliding fit, in actual use, the electric automatic door can only move the electric door bracket 3 by pushing and pulling. The upward or downward component force cannot affect the electric door bracket 3. That is, the electric door bracket 3 is not subject to the component force in the non-movement direction, which greatly reduces vibration, thereby effectively reducing wear and extending its service life, thus reducing the maintenance cost of the electric automatic door.

[0038] like Figure 2 As shown, in some embodiments of this utility model, the electric door drive component 1 includes a drive motor 11 and a lead screw and linear guide assembly 12.

[0039] The drive motor 11 is connected to the transmission end of the lead screw and linear guide assembly 12, and the lead screw and linear guide assembly 12 is provided with a lead screw slider 13.

[0040] The electric door cantilever 2 is mounted on the lead screw slider 13;

[0041] The electric door drive component 1 adopts a lead screw structure, which is based on helical transmission. Motion conversion is achieved through the threaded engagement of the lead screw and nut. Specifically, the lead screw linear guide assembly 12 is the lead screw with a helical thread machined on its surface, and the lead screw slider 13 is the nut that engages with the lead screw thread. The drive motor 11 drives the lead screw linear guide assembly 12 to rotate. Because the lead screw linear guide assembly 12 rotates, the lead screw slider 13 is constrained and cannot rotate, forced to move linearly along the lead screw axis. The lead screw structure is existing technology and will not be described in detail here.

[0042] Since the electric door cantilever 2 is mounted on the lead screw and slider 13, the linear motion of the lead screw and slider 13 can drive the electric door cantilever 2 to move.

[0043] The electric door drive component 1 adopts a lead screw structure, which has the advantages of high-precision positioning, heavy-load low-speed, and high-speed movement.

[0044] like Figure 2 As shown, in some embodiments of this utility model, the robotic arm structure 4 and the electric door cantilever 2 are integrally formed;

[0045] The robotic arm structure 4 and the electric door cantilever 2 are integrally molded, which has the following advantages:

[0046] First, it enhances structural strength. Traditional split designs require welding, bolting, or gluing for connection, and these connection points may become weak points in the structure. One-piece molding eliminates connection gaps or interfaces, resulting in a more uniform overall structure and significantly improved impact and fatigue resistance. The one-piece design can also distribute stress by optimizing the shape, thus extending the service life.

[0047] Second, simplify the manufacturing process and reduce costs;

[0048] Third, improve accuracy and consistency;

[0049] Fourth, improve reliability and durability.

[0050] like Figure 2 As shown, in some embodiments of this utility model, the electric door bracket 3 and the electric door drive component 1 are located on the same side of the electric door cantilever 2; placing the electric door bracket 3 and the electric door drive component 1 on the same side of the electric door cantilever 2 has the advantages of simplified structure and convenient installation.

[0051] like Figure 2 As shown, in some embodiments of this utility model, the cross-section of the connecting protrusion 31 is rectangular;

[0052] Because the cross-section of the connecting protrusion 31 is rectangular, its shear resistance is improved, its torque transmission efficiency is enhanced, it has high stability, and its manufacturing process is simple and the processing cost is low.

[0053] like Figure 2 As shown, in some embodiments of this utility model, a gap is left between the connecting protrusion 31 and the connecting groove 41;

[0054] A gap is left between the connecting protrusion 31 and the connecting groove 41, which not only ensures the effectiveness of transmission but also forms a mechanical buffer layer that can effectively absorb lateral vibration energy. Furthermore, due to the setting of this gap, the connection between the electric door bracket 3 and the robotic arm structure 4 has a certain margin, reducing the installation accuracy requirements.

[0055] like Figure 2 As shown, in some embodiments of this utility model, a protective layer 32 is provided on the outer surface of the connecting protrusion 31; the material of the protective layer 32 is an elastic material.

[0056] The left and right ends of the inner surface of the connecting groove 41 are provided with a second protective layer 42; the material of the second protective layer 42 is an elastic material;

[0057] Based on the above design, the part of the connecting protrusion 31 on the electric door bracket 3 that contacts the inner surface of the connecting groove 41 on the robotic arm structure 4 is made of elastic material, that is, a material with excess elasticity can be used. The material with excess elasticity includes, but is not limited to, any one of polyurethane, rubber, thermoplastic elastomer, and foam material. Polyurethane is preferred as the material with excess elasticity.

[0058] This utility model provides an electric automatic door. The connecting protrusion 31 on the electric door bracket 3 and the connecting groove 41 on the robotic arm structure 4 form an embedded sliding fit between the protrusion and the groove. This non-rigid connection method not only reduces the precision requirements for the installation of the electric door, but also effectively solves the problem of vibration caused by the high-speed operation of the electric door.
