Description

Technical Field

[0001] The utility model relates to the technical field of machine tool protection, in particular to a machine tool ceiling protection device. Background Art

[0002] Machine tools refer to machines used to manufacture machines, also known as machine tools or machine tools, and are usually referred to as machine tools. They are generally divided into metal cutting machine tools, forging machine tools, and woodworking machine tools. There are many methods for processing mechanical parts in modern machinery manufacturing: in addition to cutting, there are also casting, forging, welding, stamping, extrusion, etc. All parts with high precision requirements and fine surface roughness requirements generally need to be processed by cutting on machine tools. In order to effectively protect machine tools and prevent the overflow of water, gas, oil mist, etc. inside the machine, they are often equipped with ceiling protection.

[0003] In the field of high-end equipment manufacturing, such as rail transportation equipment, shipbuilding and marine engineering equipment, and civil aircraft, the workpieces are often large in size. Currently, most existing ceiling protections are fixed structures. However, when the workpieces are large and require the use of a crane or forklift, the fixed ceiling greatly limits the upper space of the machine tool, thereby limiting the size of the workpiece processed by the machine tool and affecting the efficiency of the machine tool.

[0004] Therefore, the existing machine tool ceiling protection is no longer applicable, which seriously affects the processing of workpieces, and there is a risk of damaging the machine tool without ceiling protection. In addition, if automatic opening and closing is to be achieved, a whole set of transmission mechanisms must be added, but at the same time, there will be problems such as large space occupation, low operating speed, loud operating noise, poor synchronization, difficulty in adjustment, overly complex mechanism, high cost and high self-weight ratio. In the event of damage, it can only be replaced as a whole, which greatly increases the operation and maintenance costs.

[0005] Therefore, how to solve the above-mentioned deficiencies in the prior art has become a topic to be studied and solved in this utility model. Summary of the invention

[0006] The utility model aims to provide a machine tool ceiling protection device.

[0012] It also includes a protective cover, each of the ceiling beams is positioned in the protective cover, and the protective cover is driven to open or fold by the power beam to open and close the protective assembly;

[0013] The translation of the power cross beam on the two supporting main beams is driven indirectly or directly by a driving mechanism.

[0014] According to a further technical solution, one end of the protective cover along the opening and closing direction is connected to the power beam, and the other end is fixed to the end of the supporting main beam.

[0015] According to a further technical solution, both ends of the power beam and the ceiling beam are provided with hanging wheels facing the supporting main beam, and the hanging wheels are movably connected to the supporting main beam.

[0016] A further technical solution is that a synchronous belt and a guide rail are provided inside the supporting main beam, the synchronous belt is arranged corresponding to the hanging wheel, and the synchronous belt is arranged close to the roller body of the hanging wheel;

[0017] The guide rail is matched with the hanging wheel.

[0018] According to a further technical solution, the power cross beams include a plurality of power cross beams, and each of the power cross beams is arranged in parallel and spaced apart in pairs.

In this case, they are only used to illustrate the positional relationship between the various structures, and are not used to limit the protection plan of this case and the specific direction during actual implementation.

[0040] See attached Figures 1 to 6 As shown, a machine tool ceiling protection device includes a protection component arranged on the top of the machine tool, and a power component for driving the protection component to open and close. The power component includes two parallel support main beams 1 arranged at intervals, and the length direction of the support main beams 1 corresponds to the opening and closing direction of the protection component. The power component also includes at least one power cross beam 2 slidably arranged between the two support main beams 1, and the power cross beam 2 is driven to translate along the opening and closing direction of the protection component, and the length of the power cross beam 2 is adapted to the spacing between the two support main beams 1.

[0041] The protection assembly includes a plurality of parallel and spaced ceiling beams 3 slidably arranged between two supporting main beams 1, and each ceiling beam 3 is driven to translate along the opening and closing direction of the protection assembly, and the length of the ceiling beam 3 is adapted to the spacing between the two supporting main beams 1. The ceiling beam 3 is parallel to the power beam 2. The protection assembly also includes a protection cover 4, each ceiling beam 3 is positioned in the protection cover 4, and the protection cover 4 is driven to open or fold by the power beam 2 to open and close the protection assembly.

[0042] And the protective cover 4 can adopt a complete protective cover 4, and can also adopt the attached Figure 1As shown, the protective cover 4 is divided into two parts, and the blank space between the two parts of the protective cover 4 is used to install the processing device of the machine tool (not shown in the figure). The two ends of the processing device along the opening and closing direction of the protective component are fixedly connected to the two parts of the protective cover 4 respectively, and the power beam 2 is connected to one of the parts of the protective cover 4, and drives the protective cover 4 of this part to translate, and in turn drives the processing device and the other part of the protective cover 4 to translate along the opening and closing direction of the protective component, thereby driving the entire protective component to open or fold.

[0043] The translation of the power beam 2 on the two supporting main beams 1 is driven indirectly or directly by a driving mechanism, such as a motor. Indirect drive means that the power output of the driving mechanism acts on a conveying device, such as a transmission belt, on the two supporting main beams 1, and drives the power beam 2 through the conveying device to translate it. Direct drive means that the power output of the driving mechanism can also directly act on the power beam 2 to move it.

[0044] Preferably, see the attached Figures 1 to 6 As shown, in this embodiment, the width of the protective cover 4 is adapted to the length of the ceiling beam 3, and the protective cover 4 is fixed to each ceiling beam 3 in sequence. The end face of the protective cover 4 along the opening and closing direction is connected to the power beam 2 at one end, and the other end is fixed to the end of the supporting main beam 1. The protective cover 4 drives the ceiling beam 3 to move on the supporting main beam 1 through the action of the power beam 2, thereby closing or unfolding on the supporting main beam 1. The utility model does not need to add an additional transmission mechanism, is simple to install, has strong durability, and greatly reduces the operation and maintenance costs.

[0045] Preferably, see the attached Figures 1 to 6 As shown, the power beam 2 and the ceiling beam 3 in this embodiment are both installed with a hanging wheel 5 on the side facing the supporting main beam 1 at both ends, and the power beam 2 and the ceiling beam 3 move on the supporting main beam 1 through the hanging wheel 5. A synchronous belt 6 and a guide rail 7 are provided inside the supporting main beam 1, and the guide rail 7 cooperates with the hanging wheel 5, and the hanging wheel 5 moves on the guide rail 7. The synchronous belt 6 is correspondingly arranged above the hanging wheel 5, and performs friction movement with the hanging wheel 5. The friction movement of the synchronous belt 6 and the hanging wheel 5 in this embodiment can reach a speed of 120 meters per minute, which greatly improves the running speed of the automatic opening and closing. Driven by the motor, the synchronous belt 6 drives the power beam 2 and the ceiling beam 3 to move on the supporting main beam 1, thereby realizing the closing or unfolding of the protective cover 4, which has the advantages of good synchronization and convenient adjustment.

[0046] Preferably, in this embodiment, the power beams 2 include multiple ones, and the power beams 2 are arranged in parallel and spaced apart. When the overall length or mass of the protection component is long, multiple power beams 2 can be used to achieve segmented drive opening and closing, thereby ensuring opening and closing efficiency and overall service life.

[0047] Preferably, see the attached Figure 1 and attached Figure 2As shown, in this embodiment, the protective cover 4 between two adjacent ceiling beams 3 is folded to form a plurality of V-shaped folded sections 8, and support bars 9 are installed at the corners of the folded sections 8. The protective cover 4 is made of hard cloth and has high bending strength. The support bars 9 are metal support bars, so as to ensure that the protective cover 4 will not sag seriously due to gravity, so that the protective cover 4 can maintain its initial shape well and is not easy to deform. And the metal material is a known metal material such as iron, copper, etc. that can be used to reinforce the protective cover 4.

[0048] Preferably, see the attached Figure 1 As shown, in this embodiment, a motor fixing seat 10 for fixing the motor is provided at the end of the supporting main beam 1.

[0049] Preferably, see the attached Figure 1 As shown, in this embodiment, the length of the power beam 2 is the same as that of the ceiling beam 3, so that the power beam 2 can drive the ceiling beam 3 to move on the supporting main beam 1.
