Description

Technical Field

[0001] This utility model relates to the field of gantry machining, specifically a protective door for a gantry machining center. Background Technology

[0002] A gantry machining center is a machining center whose spindle Z-axis is perpendicular to the worktable. Its overall structure is a large machining center with a portal frame formed by two columns and a top beam, with a crossbeam in the middle of the two columns. It is particularly suitable for machining large and complex-shaped workpieces.

[0003] To protect worker safety, gantry machining centers are equipped with safety doors. Before working in a gantry machining center, the safety doors must be closed. During the machining process, high-speed rotating tools, flying chips, and coolant spraying are involved, which pose a risk of physical injury. The safety doors directly isolate people from the machining area, preventing operators from coming into contact with moving parts or being hit by flying chips. This is a mandatory safety regulation.

[0004] However, modern gantry machining centers typically have two sets of safety doors, located on opposite sides of the machining center for easy access by workers. Since these doors must be closed promptly during operation, both sets need to be controlled separately. This process is complex and carries the risk of workers closing only one set of doors, forgetting to close the other, thus creating a safety hazard. Utility Model Content

[0005] To overcome the shortcomings of existing technology, current gantry machining centers are usually equipped with two sets of protective doors, located on opposite sides of the gantry machining center, which facilitates the entry and exit of personnel. Since the protective doors must be closed in a timely manner when the gantry machining center is in operation, it is necessary to control the closing of two sets of protective doors separately. This process is complicated and may also lead to the possibility that the personnel only close one set of protective doors and forget to close the other set, thus causing safety hazards. This utility model proposes a protective door for gantry machining centers.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The protective door of the gantry machining center of this utility model includes a base, a baffle fixedly connected to the top of the base, a machining device fixedly connected to the top of the base, and a moving mechanism provided at the top of the base. The moving mechanism includes a first moving groove and a second moving groove. The first moving groove is opened at the front of the top of the base, and the second moving groove is opened on one side of the top of the base. The first moving groove and the second moving groove are interconnected. One end of the first moving groove is rotatably connected to a first screw. The outer sides of both ends of the first screw are threaded with first moving blocks. Four sets of protective doors are provided at the top of the base.

[0007] Preferably, the end of the second movable groove away from the first screw is rotatably connected to the second screw, and the outer sides of both ends of the second screw are threaded with second movable blocks. The top ends of the first and second movable blocks are fixedly connected with protective doors, and a motor is fixedly connected to one side of the base, and the output shaft of the motor passes through the base and is fixedly connected to one end of the second screw.

[0008] Preferably, a first helical gear is fixedly connected to the end of the first screw near the second screw, and a second helical gear is fixedly connected to the end of the second screw near the first screw, wherein the first helical gear meshes with the second helical gear.

[0009] Preferably, the first moving block is adapted to the first moving slot, and the second moving block is adapted to the second moving slot.

[0010] Preferably, a stop post is fixedly connected to the outer side of the middle part of the first screw and the second screw, and the threads at both ends of the first screw and the second screw are opposite.

[0011] Preferably, the base has two sets of steps at the front and one side, and the two sets of steps are fixedly connected to the base.

[0012] The advantages of this utility model are: This invention, through the structural design of the moving mechanism, achieves the function of rotating the first screw by driving the second screw through the rotation of the motor, and rotating the first screw in conjunction with the first and second helical gears. As the first and second screws rotate, all four sets of protective doors can be simultaneously closed or opened under the control of the motor. This solves the problem that current gantry machining centers typically have two sets of protective doors, located on adjacent sides of the gantry machining center. While this facilitates worker access, the protective doors must be closed promptly during operation, requiring separate control of both sets of doors. This process is complex and may lead to workers closing only one set of protective doors, forgetting to close the other, thus creating a safety hazard. Attached Figure Description

[0016] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figures 1-3 As shown, a protective door for a gantry machining center includes a base 1, a baffle 2 fixedly connected to the top of the base 1, a machining device 3 fixedly connected to the top of the base 1, and a moving mechanism provided at the top of the base 1. The moving mechanism includes a first moving groove 4 and a second moving groove 5. The first moving groove 4 is opened at the front of the top of the base 1, and the second moving groove 5 is opened on one side of the top of the base 1. The first moving groove 4 and the second moving groove 5 are interconnected. One end of the first moving groove 4 is rotatably connected to a first screw 6. The outer sides of both ends of the first screw 6 are threaded with first moving blocks 7. Four sets of protective doors 100 are provided at the top of the base 1. During operation, the structural design of the moving mechanism enables the rotation of the second screw 8 driven by the rotation of the motor 10, which in turn drives the rotation of the first screw 6 in conjunction with the rotation of the first helical gear 11 and the second helical gear 12. As the first screw 6 and the second screw 8 rotate, all four sets of protective doors 100 can be simultaneously closed or opened under the control of the motor 10. This solves the problem that current gantry machining centers typically have two sets of protective doors 100, located on adjacent sides of the gantry machining center. While this facilitates worker access, the protective doors 100 must be closed promptly during operation, requiring separate control of both sets of protective doors 100. This process is complex and may lead to workers closing only one set of protective doors 100 while forgetting to close the other, thus creating a safety hazard.

[0018] Furthermore, such as Figure 2As shown, the end of the second moving groove 5 away from the first screw 6 is rotatably connected to the second screw 8. The outer sides of both ends of the second screw 8 are threaded with second moving blocks 9. The top ends of the first moving block 7 and the second moving block 9 are fixedly connected with protective doors 100. The base 1 is fixedly connected to one side of the motor 10, and the output shaft of the motor 10 passes through the base 1 and is fixedly connected to one end of the second screw 8. During operation, the rotation of the first screw 6 and the second screw 8 will drive the two sets of first moving blocks 7 and second moving blocks 9 to move towards each other, that is, the two sets of protective doors 100 will merge or separate, i.e., the functions of closing and opening.

[0019] Furthermore, such as Figure 3 As shown, a first helical gear 11 is fixedly connected to one end of the first screw 6 near the second screw 8, and a second helical gear 12 is fixedly connected to one end of the second screw 8 near the first screw 6. The first helical gear 11 and the second helical gear 12 mesh. During operation, since the first helical gear 11 meshes with the second helical gear 12, when the second screw 8 rotates under the drive of the motor 10, it will also drive the second screw 8 to rotate, thereby controlling the opening and closing of the four sets of protective doors 100.

[0020] Furthermore, such as Figure 2 As shown, the first moving block 7 is adapted to the first moving slot 4, and the second moving block 9 is adapted to the second moving slot 5; During operation, the rotation of the first screw 6 or the second screw 8 will cause the first moving block 7 or the second moving block 9 to have the same tendency to rotate. Since the size of the first moving block 7 or the second moving block 9 is adapted to the first moving groove 4 or the second moving groove 5, the rotation tendency of the first moving block 7 or the second moving block 9 will be hindered by the first moving groove 4 or the second moving groove 5. Furthermore, due to the threaded connection between the first moving block 7 or the second moving block 9 and the first screw 6 or the second screw 8, the first moving block 7 or the second moving block 9 can move on the first screw 6 or the second screw 8 as the first screw 6 or the second screw 8 rotates. The first screw 6 or the second screw 8 and the first moving block 7 or the second moving block 9 adopt threaded meshing transmission. The threaded pair has a natural self-locking property, and the friction angle is greater than the thread helix angle. Under static load, it can effectively prevent the first moving block 7 or the second moving block 9 from being displaced by external force. This characteristic can ensure that the position of the first moving block 7 or the second moving block 9 is fixed.

[0021] Furthermore, such as Figure 3 As shown, a stop post 13 is fixedly connected to the outer side of the middle part of the first screw 6 and the second screw 8, and the threads at both ends of the first screw 6 and the second screw 8 are opposite. During operation, the threads of the first screw 6 and the second screw 8 about the limit post are opposite. Therefore, when the first screw 6 and the second screw 8 rotate, the two sets of first moving blocks 7 and second moving blocks 9 inside the same moving groove will move towards each other. The limit post can prevent the two sets of first moving blocks 7 and second moving blocks 9 from colliding with each other.

[0022] Furthermore, such as Figure 1 As shown, two sets of steps 14 are provided on the front and one side of the base 1, and the two sets of steps 14 are fixedly connected to the base 1. During operation, step 14 facilitates workers to enter the device body to prepare for processing when the protective door 100 is opened.

[0023] Working principle: When the worker enters the top of the base 1 to prepare for gantry processing, the motor 10 needs to be turned on so that the motor 10 rotates and drives the second screw 8 and the second helical gear 12 to rotate, which in turn drives the first helical gear 11 and the first screw 6 to rotate. As the first screw 6 and the second screw 8 rotate, the two sets of first moving blocks 7 and the first moving blocks 7 drive the protective door 100 to move towards the ends of the first screw 6 and the second screw 8. In this way, the worker can enter the top of the base 1 through the step 14 to work. After the work is completed, the worker leaves the base 1 and turns on the motor 10 in the opposite direction so that the corresponding protective door 100 moves in the opposite direction and closes. After confirming that all protective doors 100 are closed, the gantry processing work is carried out.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
