DETAILED DESCRIPTION

[0022] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0023] See also Figure 1 The utility model provides a single-opening CNC machine isolation door, including a casing 1, a slide rail 2, an isolation door 3, a convenient loading and unloading mechanism 4 and an anti-collision mechanism 5. Two slide rails 2 are arranged in parallel on the upper and lower parts of the inner side of the casing 1, the isolation door 3 is arranged on the slide rail 2, a convenient loading and unloading mechanism 4 is arranged between the slide rail 2 and the isolation door 3, and an anti-collision mechanism 5 is arranged on the top plane of the isolation door 3.

[0024] See also Figure 2-3The convenient loading and unloading mechanism 4 in the utility model includes a slide seat 41, a No. 1 mounting hole 42, a docking groove 43 and a No. 2 mounting hole 44. An L-shaped slide seat 41 is slidably installed on the surface of the slide rail 2. The slide seat 41 moves linearly along the slide rail 2. The surface of the slide seat 41 is provided with a No. 1 mounting hole 42. The top and bottom tails of the isolation door 3 are provided with docking grooves 43. The docking grooves 43 match the shape and size of the slide seat 41. The isolation door 3 is buckled and assembled to the surface of the slide seat 41 through the docking grooves 43. The surface of the isolation door 3 is provided with a No. 2 mounting hole 44, and the No. 2 mounting hole 44 is provided. The mounting holes 44 pass through the inner side of the docking groove 43, and the number of the No. 2 mounting holes 44 is the same as that of the No. 1 mounting holes 42. The No. 2 mounting holes 44 and the No. 1 mounting holes 42 are connected and fixed by screws, so that the isolation door 3 is installed and fixed to the slide seat 41. The isolation door 3 can be moved linearly along the slide rail 2 through the slide seat 41 to realize the opening and closing action, and the isolation door 3 can be removed from the slide seat 41 for maintenance and replacement by simply removing the screws between the No. 2 mounting holes 44 and the No. 1 mounting holes 42. The operation is simple and quick, which reduces the downtime of the machine tool equipment.

[0025] It is further explained that the number of No. 1 mounting holes 42 on the surface of the slide seat 41 is not less than three, and the No. 1 mounting holes 42 are evenly distributed on the surface of the slide seat 41. Multiple screw connections can ensure that the isolation door 3 and the slide seat 41 are firmly connected and not prone to shaking.

[0026] It is further explained that the horizontal length of the slide 41 is at least half of the horizontal length of the isolation door 3, so that the slide 41 and the docking groove 43 have sufficient connection strength to ensure that the isolation door 3 and the slide 41 are firmly installed and not easy to loosen.

[0027] See also Figure 4-5 The anti-collision mechanism 5 in the utility model includes an assembly groove 51, a pipe sleeve 52, a telescopic rod 53, a buffer spring 54, a support leg 55 and a storage cavity 56. The top plane of the isolation door 3 is provided with an assembly groove 51, and the end of the assembly groove 51 passes through the left and right sides of the isolation door 3. The inner side of the assembly groove 51 is provided with a pipe sleeve 52, and the inner cavity of the tail end of the pipe sleeve 52 is provided with a telescopic rod 53, wherein the fixed section of the telescopic rod 53 is fixed with screws to the inner wall of the pipe sleeve 52, and the surface of the fixed section of the telescopic rod 53 is provided with a buffer spring 54, and the buffer spring 54 is provided on the surface of the fixed section of the telescopic rod 53. One end of the impact spring 54 is in conflict with the inner wall of the sleeve 52, and the other end of the buffer spring 54 is in conflict with the telescopic section of the telescopic rod 53, so that the telescopic rod 53 remains in a pop-up state. The telescopic section of the telescopic rod 53 extends outward from the inner side of the sleeve 52 and is fixed with the support leg 55 by screws. Receiving cavities 56 are provided at the left and right ends of the assembly groove 51. The shape and size of the receiving cavity 56 match the support leg 55. The support leg 55 can be retracted into the inner side of the receiving cavity 56 and combined with the isolation door 3 to ensure that the isolation door 3 can be closed normally.

[0028] To further explain, there are two groups of telescopic rods 53, buffer springs 54 and support legs 55, and the above-mentioned components are symmetrically arranged at the left and right ends of the pipe sleeve 52, so that the anti-collision mechanism 5 can provide anti-collision protection for the isolation door 3 in both left and right directions, protecting the isolation door 3 from strong collision with the casing 1 during the opening and closing action.

[0029] To further explain, a rubber pad is attached to the side of the support foot 55 close to the housing 1, wherein the thickness of the rubber pad is not less than 5 mm, so that the support foot 55 can flexibly contact with the housing 1, reduce the impact force, and avoid abnormal noise.

[0030] To further illustrate, the pipe sleeve 52 is installed with the assembly groove 51 by a detachable connection, which can be achieved by screw connection, screw connection, snap connection, etc., allowing the pipe sleeve 52 and the assembly groove 51 to be repeatedly disassembled and assembled, so that the isolation door 3 and the pipe sleeve 52 can be removed and replaced separately, and the intact parts can be retained for continued use to reduce replacement costs.

[0031] Here’s how it works:

[0032] First, during the production process of machine tools, some production processes may endanger the personal safety of operators, so an isolation door 3 is usually set to separate the machine tool and the workers to ensure the safety of the workers' operation.

[0033] Second, when controlling the isolation door 3 to perform the opening and closing action, since the isolation door 3 has been installed and fixed with the slide seat 41, the isolation door 3 can be moved linearly along the slide rail 2 through the slide seat 41 to realize the opening and closing action. By setting an anti-collision mechanism 5 on the top plane of the isolation door 3, during the closing process of the isolation door 3, the support foot 55 will contact the casing 1 before the isolation door 3, and then as the distance between the isolation door 3 and the casing 1 decreases, the telescopic rod 53 will gradually shrink, thereby causing the buffer spring 54 to be compressed, and the elastic force of the buffer spring 54 is used to slow down the moving speed of the isolation door 3 to protect the isolation door 3 from colliding strongly with the casing 1 during the opening and closing action, so as to extend the service life of the isolation door 3 and avoid the isolation door 3 from malfunctioning under frequent collisions and affecting the normal use of the machine tool. Among them, by opening a storage cavity 56 at the end of the assembly groove 51, the support foot 55 can be retracted into the inner side of the storage cavity 56 and combined with the isolation door 3 to ensure that the isolation door 3 can be closed normally.

[0034] Third, since the service life of the machine tool is relatively long and can generally be used for several years to more than ten years, the isolation door 3 will inevitably malfunction in long-term production. Common faults include: the electromagnetic lock on the isolation door 3 will be damaged due to frequent collisions, resulting in the isolation door 3 being unable to close normally. If the isolation door cannot be closed normally, the safety program of the CNC machine tool will not allow the system to execute operation commands and can only be shut down for maintenance. By setting an anti-collision mechanism 5 on the top plane of the isolation door 3, the isolation door 3 can be removed from the slide seat 41 for maintenance and replacement by simply removing the screws between the No. 2 mounting hole 44 and the No. 1 mounting hole 42. The operation is simple and quick, reducing the downtime of the machine tool equipment. In addition, the pipe sleeve 52 is installed with a detachable connection and the assembly groove 51, allowing the pipe sleeve 52 and the assembly groove 51 to be repeatedly disassembled and assembled, so that the isolation door 3 and the pipe sleeve 52 can be removed and replaced separately, and the intact parts can be retained for continued use to reduce the replacement cost.

[0035] Fourth, when installing the isolation door 3, first snap the docking grooves 43 of the upper and lower parts of the isolation door 3 onto the surface of the slide seat 41 at the corresponding position, and then use screws to connect and fix the No. 2 mounting hole 44 with the No. 1 mounting hole 42. The installation of the isolation door 3 can be completed. The operation is simple and quick, and the downtime of the machine tool equipment is reduced.

[0036] The utility model provides a single-opening CNC machine tool isolation door, which has a convenient loading and unloading mechanism 4 between the slide rail 2 and the isolation door 3. The isolation door 3 can be removed from the slide seat 41 for maintenance and replacement by removing the screws between the No. 2 mounting hole 44 and the No. 1 mounting hole 42. The operation is simple and quick, and the downtime of the machine tool equipment is reduced. An anti-collision mechanism 5 is set on the top plane of the isolation door 3. During the closing process of the isolation door 3, the support foot 55 will contact the casing 1 before the isolation door 3. Then, as the distance between the isolation door 3 and the casing 1 is reduced, the telescopic rod 53 will gradually shrink, thereby compressing the buffer spring 54. The elastic force of the buffer spring 54 is used to slow down the moving speed of the isolation door 3, and the isolation door 3 is protected from a strong collision with the casing 1 during the opening and closing action, so as to extend the service life of the isolation door 3.

[0037] The above description is only a preferred example of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
