Description

Technical Field

[0001] The invention relates to the field of machine tools, in particular to a machine tool material protection automatic door with smooth movement. Background Art

[0002] With the development of technology, agile logistics conveying systems have gradually replaced the original manual production line loading and unloading conveying methods. Flexible production lines with machining centers as the core and truss manipulators as agile logistics systems have been widely used. At the same time, the change in the way workpieces are conveyed on this production line also directly requires the protective structure of the machine tool. That is to say, the protective door located at the loading position of the machine tool needs to be able to achieve fast, smooth and reliable opening and closing actions to meet the requirements of automated loading. Traditional protective doors are generally connected to the machine tool housing through a sliding slide rail structure and driven by a cylinder located on one side of the protective door. Since the cylinder directly acts on one side of the protective door, the other side of the protective door will be subjected to a certain degree of bending moment during the movement, which is commonly known as "different strength". This situation often causes the protective door to get stuck, pause, and other problems, resulting in its unsmooth and unreliable movement; if a cylinder that can move synchronously is set on both sides of the protective door, the above problem can be solved, but this will increase the cost of the protective door. Therefore, a method or device that can solve the above problem is now needed. Summary of the invention

[0003] The present invention aims to solve the above-mentioned deficiencies in the prior art and proposes an automatic door for protecting machine tool materials which has a simple structure, ingenious design, reasonable layout and can ensure smooth movement without jamming.

[0004] The technical solution of the present invention is: a machine tool material protection automatic door with smooth movement, characterized in that: the protection automatic door comprises two symmetrically arranged door panels 1, the door panels 1 are connected to multiple sliders 3 one by one through multiple slider connection mechanisms 2, the sliders 3 are slidably connected to the slide rails 4, the slide rails 4 are two symmetrically distributed, and the slide rails 4 are fixedly supported on the machine tool housing, and the machine tool housing is also provided with a cylinder 5, and the working end of the cylinder 5 is connected to one side of the door panel 1 through a cylinder connection mechanism 6,

[0005] The slider connection mechanism 2 includes a limit plate 8 connected to the top surface of the slider 3 through a pressure plate 7, and the connection mechanism 2 also includes a connection plate 9 fixedly connected to the door panel 1, and the connection plate 9 is provided with rectangular holes 10 corresponding to a plurality of sliders 3, and the limit plate 8 is movably connected in the rectangular hole 10, and the width of the limit plate 8 is the same as the width of the rectangular hole 10, while the length of the rectangular hole 10 is greater than the length of the limit plate 8, and the width of the pressure plate 7 is greater than the width of the rectangular hole 10.

[0006] The cylinder connecting mechanism 6 includes a connecting sleeve 12 threadedly connected to the end of the cylinder working shaft 11, and a first backup nut 13 matching the connecting sleeve 12 is also threadedly connected to the cylinder working shaft 11. A connecting hole is provided at one end of the connecting sleeve 12 away from the cylinder working shaft 11, and a spherical end 15 of the connecting shaft 14 is movably connected to the inner cavity of the connecting sleeve 12 through the connecting hole. The other end of the connecting shaft 14 is inserted into a through hole opened on the door panel connecting plate 19, and second backup nuts 16 threadedly connected to the connecting shaft 14 are respectively arranged on both sides of the door panel connecting plate 19.

[0008] Compared with the prior art, the present invention has the following advantages:

[0009] This type of structural form of machine tool material loading protection automatic door with smooth movement has a simple structure, ingenious design, and reasonable layout. It is designed with two sets of special connection structures to address the situation that traditional single-side driven protection automatic doors are prone to pause or even get stuck due to bending moments during movement. Both sets of connection structures leave a certain amount of clearance in the direction of movement. Therefore, even if the cylinder on one side generates a bending moment on the other side of the protection door during operation, the above clearance can effectively eliminate the bending moment and ensure that the protection door can move smoothly, thereby realizing the function of opening or closing. In addition, the manufacturing process of this protection automatic door is simple and the manufacturing cost is low. Therefore, it can be said that it has many advantages and is particularly suitable for promotion and application in this field. Its market prospects are very broad. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The specific implementation of the present invention will be described below with reference to the accompanying drawings. Figure 1 , Figure 2 , Figure 3 , Figure 4As shown: a machine tool material protection automatic door with smooth movement, which includes two symmetrically arranged door panels 1, wherein the door panels 1 are connected to a plurality of sliders 3 one by one through a plurality of slider connection mechanisms 2, and the sliders 3 are slidably connected to slide rails 4, wherein the slide rails 4 are two symmetrically distributed, and the slide rails 4 are fixedly supported on the machine tool housing, and a cylinder 5 is also arranged on the machine tool housing, and the working end of the cylinder 5 is connected to one side of the door panel 1 through a cylinder connection mechanism 6,

[0015] The slider connection mechanism 2 includes a limit plate 8 connected to the top surface of the slider 3 through a pressure plate 7, and the connection mechanism 2 also includes a connection plate 9 fixedly connected to the door panel 1, and the connection plate 9 is provided with rectangular holes 10 corresponding to a plurality of sliders 3, and the limit plate 8 is movably connected in the rectangular hole 10, and the width of the limit plate 8 is the same as the width of the rectangular hole 10, while the length of the rectangular hole 10 is greater than the length of the limit plate 8, and the width of the pressure plate 7 is greater than the width of the rectangular hole 10.

[0016] The cylinder connecting mechanism 6 includes a connecting sleeve 12 threadedly connected to the end of the cylinder working shaft 11, and a first backup nut 13 matching the connecting sleeve 12 is also threadedly connected to the cylinder working shaft 11. A connecting hole is provided at one end of the connecting sleeve 12 away from the cylinder working shaft 11, and a spherical end 15 of the connecting shaft 14 is movably connected to the inner cavity of the connecting sleeve 12 through the connecting hole. The other end of the connecting shaft 14 is inserted into a through hole opened on the door panel connecting plate 19, and second backup nuts 16 threadedly connected to the connecting shaft 14 are respectively arranged on both sides of the door panel connecting plate 19.

[0017] A limiting protrusion 17 is disposed on the back side of the spherical end head 15 , and a limiting groove 18 matching the limiting protrusion 17 is disposed at the connecting hole of the connecting sleeve 12 .

[0018] The working process of the smooth-moving machine tool material protection automatic door of the embodiment of the present invention is as follows: when the door panel 1 needs to be opened or closed, the control system controls the cylinder 5 to move, and the cylinder 5 drives the door panel 1 to slide along the slide rail 4 to achieve the above purpose; in this process, since a clearance is provided in the slider connection mechanism 2 connecting the door panel 1 and the slider 3, and a clearance is also provided in the cylinder connection mechanism 6 connecting the working end of the cylinder 5 and the door panel 1, even if the cylinder 5 in the device is only provided on one side of the door panel 1, when the door panel 1 is driven to move, the door panel 1 will not be stuck, stagnant, etc.;

[0019] For the slider connection mechanism 2, since there is a gap between the connection plate 9 and the rectangular hole 10 in the length direction of the rectangular hole 10, when the bending moment is transmitted to the connection plate 9, the connection plate 9 can move relatively in the rectangular hole 10, that is, the slider 3 and the slider connection mechanism 2 will automatically adjust to eliminate the bending moment, ensuring that the slider 3 can slide smoothly with the slide rail 4;

[0020] For the cylinder connecting mechanism 6, since the connecting shaft 14 and the inner cavity of the connecting sleeve 12 are connected through the spherical end head 15, and the inner diameter of the connecting hole on the connecting sleeve 12 is larger than the outer diameter of the connecting shaft 14, that is, there is a certain gap between the two, in this way, during the motion transmission process, even if bending moment occurs due to deflection and other problems, the connecting shaft 14 can transmit the force transmitted by the connecting sleeve 12 to the door panel connecting plate 19, and finally drive the door panel 1 to move; at the same time, if the connecting shaft 14 and the connecting sleeve 12 are to be fixed, the operator can further tighten the cylinder working shaft 11, so that the end of the cylinder working shaft 11 can tighten the spherical end head 15 on the connecting sleeve 12, and at this time, the limiting protrusion 17 on the back side of the spherical end head 15 enters the limiting groove 18 on the connecting sleeve 12, and the spherical end head 15 cannot achieve relative movement with the connecting sleeve 12.
