Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machining centers, in particular to a tool magazine door combination structure of a machining center. Background Art

[0002] CNC machining centers have the advantages of strong adaptability, high machining precision, stable machining quality and high production efficiency. They comprehensively apply the technological achievements of electronic computers, automatic control, servo drives, precision measurement and new mechanical structures. During the processing of workpieces, the machining center will produce a large amount of flying metal debris. In order to protect the tool magazine and the tools installed on it from being contaminated by the debris, it is usually necessary to set a tool magazine door structure inside the machining center to enclose the tool magazine.

[0003] When the staff needs to maintain the tool magazine or replace the tools on it, they need to open the tool magazine door and then close it after completion. The existing tool magazine door of the machining center needs to be opened or closed manually. Due to the limited internal space of the machining center, manual opening or closing of the tool magazine door is inconvenient and unsafe. Utility Model Content

[0004] The utility model provides a tool magazine door combination structure for a machining center, which solves the technical problem in the prior art that the tool magazine door needs to be opened or closed manually, resulting in inconvenient operation and low safety.

[0005] In view of the above problems, the technical solution proposed by the present invention is:

[0006] A tool magazine door assembly structure for a machining center comprises a machining center body, a machine head installed inside the machining center body, and a tool magazine arranged at the front end of the machine head. The tool magazine door assembly structure further comprises a set of protective doors for shielding the tool magazine, and the bottom ends of the protective doors are rotatably connected to coupling shafts on both sides, a bottom baffle is fixedly connected to the coupling shaft, the top end of the machining center body is fixedly connected to a bracket, two sets of sliding rods are fixedly connected to the bracket, and sliding sleeves are also fixedly connected to both sides of the top end of the protective door, and the two sets of sliding sleeves are respectively slidably sleeved on the surfaces of the two sets of sliding rods;

[0007] Among them, a lifting component for driving the protective door to move up and down is provided between the bracket and the protective door, and a driving component for driving the two groups of connecting shafts to rotate is provided between the machining center body and the two groups of connecting shafts.

[0008] Furthermore, the lifting assembly includes a servo motor fixedly mounted on the top of the bracket, a screw connected to one end of the servo motor output shaft and extending into the interior of the machining center body, and a screw sleeve fixedly connected to the top of the protective door and threadedly sleeved on the surface of the screw.

[0009] Furthermore, the driving assembly includes two sets of gear plates respectively connected to the ends of the two couplings, and two sets of racks fixedly connected to the inside of the machining center body. The two sets of racks face opposite directions and are respectively engaged with the two sets of gear plates.

[0010] Furthermore, an inspection door is provided on the side wall of the machining center body, and transparent observation windows are provided on the side walls of the inspection door and the protective door.

[0011] Furthermore, a blocking piece is fixedly connected to the bottom end of the sliding rod.

[0012] Furthermore, an opening is provided at the top of the machining center body, and the size of the opening is larger than the protective door.

[0013] Compared with the prior art, the beneficial effect of the present invention is that the protective door can be driven to rise or fall vertically through the lifting assembly. When the protective door rises vertically, it will move to the top of the machining center body. At the same time, the two sets of bottom baffles at the bottom will flip open under the action of the driving assembly. At this time, the protective door and the bottom baffle will not affect the maintenance of the tool magazine or the replacement of the tools on the tool magazine. During the vertical descent of the protective door, it will surround and block the tool magazine. At the same time, the two sets of bottom baffles at the bottom will flip and close under the action of the driving assembly, which can prevent the tool magazine or the tools thereon from being contaminated. It can be seen that when maintaining the tool magazine or replacing the tools thereon, people no longer need to manually control the opening and closing of the tool magazine door, which makes the operation more convenient and also improves safety.

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0024] See also Figure 1-6A tool magazine door combination structure for a machining center includes a machining center body 1, a machine head 2 installed inside the machining center body 1, and a tool magazine 3 arranged at the front end of the machine head 2. The tool magazine door combination structure also includes a set of protective doors 4, which can be used to shield and protect the tool magazine 3, and the bottom ends of the protective doors 4 are rotatably connected to the two sides of the coupling shaft 5, and the coupling shaft 5 is fixedly connected to the bottom baffle 6. A driving assembly for driving the two sets of coupling shafts 5 to rotate is provided between the machining center body 1 and the two sets of coupling shafts 5. When the two sets of coupling shafts 5 drive the bottom baffles 6 to rotate relative to each other, the two sets of bottom baffles 6 can be closed from The bottom end of the protective door 4 is closed, and a bracket 9 is fixedly connected to the top of the machining center body 1. A lifting component for driving the protective door 4 to move up and down is provided between the bracket 9 and the protective door 4. Two groups of slide bars 7 are fixedly connected to the bracket 9, and sliding sleeves 8 are also fixedly connected on both sides of the top of the protective door 4. The two groups of sliding sleeves 8 are respectively slidably sleeved on the surfaces of the two groups of slide bars 7. When the protective door 4 is driven, the protective door 4 will drive the sliding sleeves 8 to slide on the surface of the sliding bar 7, so that the protective door 4 can maintain a vertical track and slide up and down under the guidance of the sliding bar 7 and the sliding sleeve 8.

[0025] When in use, the protective door 4 is driven by the lifting assembly to vertically descend. During the vertical descent of the protective door 4, the driving assembly can drive the two sets of connecting shafts 5 at the bottom of the protective door 4 to rotate relative to each other, and the two sets of bottom baffles 6 will flip in the opposite direction in the direction of mutual closure under the drive of the two sets of connecting shafts 5. When the protective door 4 drops to the lowest point, the side walls of the protective door 4 can block and protect the surrounding of the tool magazine 3. At this time, the two sets of bottom baffles 6 will also close to each other, thereby sealing the bottom end of the protective door 4. When the machine head 2 processes the workpiece fixed inside the machining center body 1, the protective door 4 and the two closed connecting shafts 5 at its bottom can effectively prevent the generated debris from splashing onto the tool magazine 3 or the tool installed thereon, thereby preventing the tool magazine 3 or the tool from being contaminated. In addition, when the tool magazine 3 needs to be cleaned When maintenance is carried out or the tools on it need to be replaced, the protective door 4 is driven to rise vertically by the lifting assembly. During the rising process of the protective door 4, the driving assembly can drive the two sets of connecting shafts 5 at the bottom of the protective door 4 to rotate relative to each other in opposite directions, and the two sets of bottom baffles 6 will flip in the opposite direction in the direction of separation driven by the two sets of connecting shafts 5. When the protective door 4 rises to the highest point, its top will contact the bracket 9. Since the protective door 4 is located above the machining center body 1, its side walls no longer block and protect the tool magazine 3. At this time, the two sets of bottom baffles 6 will also flip each other to the two sides of the bottom of the protective door 4 and separate, thereby making the bottom end of the protective door 4 open. At this time, the protective door 4 and the bottom baffle 6 will not affect the maintenance of the tool magazine 3 or the replacement of the tools on the tool magazine 3.

[0026] For further information, see Figure 1-4The lifting assembly includes a servo motor 10 fixedly mounted on the top of the bracket 9, a screw 11 connected to one end of the output shaft of the servo motor 10 and extending into the interior of the machining center body 1, and a screw sleeve 12 fixedly connected to the top of the protective door 4 and threadedly sleeved on the surface of the screw 11.

[0027] Starting the servo motor 10 can make the output shaft of the servo motor 10 drive the screw 11 to rotate in both forward and reverse directions. During this process, the screw 11 will drive the screw sleeve 12 threadedly connected thereto to rise or fall along its surface, thereby causing the protective door 4 connected to the screw sleeve 12 to be driven to rise or fall.

[0028] For further information, see Figure 1-6 The driving assembly includes two sets of gear plates 13 connected to the ends of the two connecting shafts 5, and two sets of racks 14 fixedly connected to the inside of the machining center body 1. The two sets of racks 14 face opposite directions and mesh with the two sets of gear plates 13 respectively.

[0029] When the protective door 4 rises or falls, it will drive the gear discs 13 at the ends of the two sets of connecting shafts 5 to rise or fall. During this process, the two sets of gear discs 13 will rotate under the driving action of the racks 14. Since the two sets of racks 14 are in opposite directions, the rotation directions of the two sets of gear discs 13 will also rotate in opposite directions, driving the two sets of connecting shafts 5 to rotate.

[0030] For further information, see Figure 1-6 An inspection door 15 is provided on the side wall of the machining center body 1 , and transparent observation windows 16 are provided on the side walls of the inspection door 15 and the protective door 4 .

[0031] The inspection door 15 is mounted on the side wall of the machining center body 1 by screws, so it can be removed from the machining center body 1 as needed. Through the transparent observation window 16, people can intuitively see the tool magazine 3 that is enclosed and shielded by the protective door 4 from the outside, so that when the machining center is running, the operation of the tool magazine 3 can be intuitively observed.

[0032] For further information, see Figure 1-4 The bottom end of the slide bar 7 is fixedly connected with a blocking piece 17.

[0033] During the lifting and lowering process of the protective door 4, the protective door 4 drives the sliding sleeve 8 to slide along the direction of the sliding rod 7. When the sliding sleeve 8 slides to contact the baffle 17 at the bottom end of the sliding rod 7, it can no longer slide downward. At this time, the protective door 4 drops to the lowest point and surrounds the tool magazine 3. The baffle 17 can prevent the sliding sleeve 8 from escaping from the outside of the sliding rod 7.

[0034] For further information, see Figure 1-4 An opening 18 is provided at the top of the machining center body 1 , and the size of the opening 18 is larger than the protective door 4 .

[0035] Since the size of the opening 18 at the top of the machining center body 1 is larger than the protective door 4, when the protective door 4 slides upward, its top will not contact the top plate of the machining center body 1, ensuring that it can smoothly rise to the top of the machining center body 1 without being blocked.

[0036] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
