Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a switching assembly for the optomechanical machining head of a multi-head machining center. Background Technology

[0002] Machining centers are automated machining equipment developed from general milling machines. The machining processes are basically the same, and their structures are somewhat similar. They are divided into two main categories: those without a tool magazine and those with a tool magazine. CNC milling machines with a tool magazine are also called machining centers.

[0003] In existing technologies, traditional multi-head machining centers require the entire optical engine to be disassembled due to the integrated design of the machining head and optical path system, resulting in redundant switching processes. Furthermore, the fixing method relies on rigid contact and lacks buffer design, making the components susceptible to stress damage.

[0004] To address this, a switching assembly for the optomechanical machining head of a multi-head machining center is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a switching assembly for the optomechanical processing head of a multi-head machining center, which can solve the problems of redundancy in the existing disassembly process and the risk of component damage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-head machining center optomechanical processing head switching assembly, comprising a machining table, a column fixedly connected to the top of the machining table, a transmission module fixedly connected to the top of the column, a bearing block slidably connected to the inner side of the transmission module, an optical path system fixedly connected to the inner side of the bearing block, a convenient switching mechanism movably connected to the bottom of the optical path system, a transmitter head movably connected to the bottom of the convenient switching mechanism, an elastic connecting assembly movably connected to the inner side of the convenient switching mechanism, the convenient switching mechanism comprising a transfer plate, the transfer plate fixedly connected to the bottom of the optical path system, a docking plate snapped into the bottom of the transfer plate, the transmitter head fixedly connected to the bottom of the docking plate, fixing rods provided on both sides of the docking plate, and an elastic connecting assembly movably connected to one side of the two fixing rods, and fixing components movably connected to the outer sides of the fixing rods and the transfer plate.

[0007] Preferably, the elastic connection assembly includes a travel groove, which is formed on the side of the fixed rod near the docking plate, and a telescopic column is fixedly connected to the inner side of the travel groove.

[0008] Preferably, a compression spring is fixedly connected to the inner side of the telescopic column.

[0009] Preferably, a contact plate is fixedly connected to the side of the telescopic column near the docking plate.

[0010] Preferably, the fixing component includes two sliding rails, which are fixedly connected to the front and rear sides of the transfer plate. Sliding blocks are slidably connected to both sides of the inner side of each sliding rail. A connecting power arm is fixedly connected to the top of each sliding block, and the other end of the connecting power arm is fixedly connected to the outside of the fixing rod.

[0011] Preferably, an electronic telescopic rod is fixedly connected to the top of the sliding rail, a lifting rod is fixedly connected to the top of the electronic telescopic rod, and linkage rods are rotatably connected to both sides of the lifting rod, with the other ends of the two linkage rods respectively rotatably connected to the opposite sides of the two linkage arms.

[0012] Preferably, both sides of the docking plate are provided with fixing slots, and fixing blocks are engaged inside the fixing slots.

[0013] Preferably, the fixing block is fixedly connected to the outside of the contact plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application enables quick switching of the processing head of a laser multi-head machining center by setting up a convenient switching mechanism, effectively reducing the redundancy of the operation process. By designing the transmitter head and the optical path system as separate structures, the optical path system is kept fixed. The docking plate on the top of the transmitter head and the transfer plate at the bottom of the optical path system are used to achieve snap-fit ​​positioning. Then, the electronic telescopic rod linkage structure drives the fixing rod to clamp the docking plate from both sides to complete the fixation. There is no need to completely dismantle the optical path system, thus solving the problem of redundant switching process caused by the integrated design of the processing head and the optical path system in traditional multi-head machining centers.

[0016] 2. By setting up an elastic connection component, this application can reduce the risk of damage to the docking plate and its internal structure by the fixing rod. By setting an elastic element on the fixing rod consisting of a telescopic column with a compression spring and an elastic contact plate, when the fixing rod contacts the docking plate, the elastic material of the contact plate initially offsets the contact stress. When the fixing rod is further advanced, the telescopic column and the compression spring contract to generate a push back to further offset the stress, thus avoiding rigid contact between the fixing rod and the docking plate. This solves the problem that the fixing method relies on rigid contact and lacks a buffer design, which makes the components susceptible to stress damage. Attached Figure Description

[0022] 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 protection scope of the present utility model.

[0023] Please see Figure 1-4 The present invention provides the following technical solution:

[0024] A multi-head machining center optomechanical head switching assembly includes a machining table 1, a column 2 fixedly connected to the top of the machining table 1, a transmission module 3 fixedly connected to the top of the column 2, a bearing block 4 slidably connected to the inner side of the transmission module 3, an optical path system 5 fixedly connected to the inner side of the bearing block 4, a convenient switching mechanism 6 movably connected to the bottom of the optical path system 5, a transmitter head 7 movably connected to the bottom of the convenient switching mechanism 6, and an elastic connecting component 8 movably connected to the inner side of the convenient switching mechanism 6. The convenient switching mechanism 6 includes a transfer plate 61, which is fixedly connected to the bottom of the optical path system 5. A docking plate 62 is snapped into the bottom of the transfer plate 61, and the transmitter head 7 is fixedly connected to the bottom of the docking plate 62. Fixing rods 63 are provided on both sides of the docking plate 62, and the elastic connecting component 8 is movably connected to the opposite side of the two fixing rods 63. Fixing components 64 are movably connected to the outer sides of the fixing rods 63 and the transfer plate 61.

[0025] In this embodiment: instead of replacing the entire unit, the transmitter 7 is separated from the optical path system 5. The optical path system 5 is connected to the transmission module 3 on the top of the optomechanical processing table 1. Its bottom has a transmission plate 61 for transmitting laser and other media and information. The top of the transmitter 7 has a docking plate 62 for introducing laser and recording information media. The transmission plate 61 and the docking plate 62 have grooves that can be interlocked. Therefore, the model of transmitter 7 can be quickly changed by simply installing the corresponding model at the bottom of the docking plate 62. When switching, the protruding part of the docking plate 62 to be replaced is first inserted into the transmission plate 61 to achieve alignment and preliminary positioning of the optical path system 5. Then, the fixing component 64 is used to clamp and install the docking plate 62 from both sides to the center.

[0026] Specifically, such as Figure 2 , Figure 4 As shown, the elastic connection assembly 8 includes a travel groove 81, which is formed on the side of the fixed rod 63 near the docking plate 62. A telescopic column 82 is fixedly connected to the inner side of the travel groove 81.

[0027] Specifically, such as Figure 2 , Figure 4 As shown, a compression spring 83 is fixedly connected to the inner side of the telescopic column 82.

[0028] Specifically, such as Figure 2 , Figure 4 As shown, a contact plate 84 is fixedly connected to the side of the telescopic column 82 near the docking plate 62.

[0029] In this embodiment: the fixing rod 63 does not directly contact the two sides of the docking plate 62. Instead, the docking plate 62 is provided with an elastic element composed of a telescopic column 82 with an embedded compression spring 83. This elastic element can fully retract to the inside of the stroke groove 81 inside the fixing rod 63. There is a contact plate 84 of elastic material on the outside of the telescopic column 82. When the two fixing rods 63 move inward, the contact plate 84 first contacts and initially offsets the stress. When the fixing rods 63 are pushed forward again, the telescopic column 82 and the embedded compression spring 83 retract and push back to further offset the stress until the telescopic column 82 is fully retracted into the stroke groove 81 and the fixing rod 63 is in contact with the contact plate 84, thus completing the clamping and fixing, thereby reducing the risk of damage.

[0030] Specifically, such as Figure 3 As shown, the fixing component 64 includes two sliding rails 6401, which are fixedly connected to the front and rear sides of the transfer plate 61. Sliding blocks 6402 are slidably connected to both sides of the inner side of the sliding rails 6401. A connecting power arm 6403 is fixedly connected to the top of the sliding block 6402, and the other end of the connecting power arm 6403 is fixedly connected to the outside of the fixing rod 63.

[0031] Specifically, such as Figure 3As shown, an electronic telescopic rod 6404 is fixedly connected to the top of the sliding rail 6401, and a lifting rod is fixedly connected to the top of the electronic telescopic rod 6404. Both sides of the lifting rod are rotatably connected to linkage rods 6406, and the other ends of the two linkage rods 6406 are respectively rotatably connected to the opposite side of the two linkage arms 6403.

[0032] In this embodiment: by activating the electronic telescopic rods 6404 on both sides of the transfer plate 61 and the top of the sliding rail 6401, the electronic telescopic rods 6404 extend upward, causing the lifting block 6405 to rise. The rise of the lifting block 6405 causes the linkage rods 6406 on both sides to flip downward, pulling the linkage arm 6403. One end of the linkage arm 6403 is connected to the sliding block 6402 in the sliding rail 6401, and the other end is connected to the fixing rod 63 that fixes the docking plate 62. After being limited by the sliding rail 6401, the fixing rods 63 on both sides move inward at the same time, clamping the docking plate 62 from both sides towards the center.

[0033] Specifically, such as Figure 4 As shown, both sides of the docking plate 62 are provided with fixing slots 9, and fixing blocks 10 are engaged inside the fixing slots 9.

[0034] Specifically, such as Figure 4 As shown, the fixing block 10 is fixedly connected to the outside of the contact plate 84.

[0035] In this embodiment, a fixing slot 9 and a fixing block 10 are provided between the docking plate 62 and the contact plate 84 for further locking and fixing.

[0036] Working Principle: When switching the optomechanical processing head of a laser multi-head machining center, it is usually necessary to disassemble and replace the entire laser emitting component, including the optical path system 5 and the laser emitting head 7, to achieve different processing with different laser emitting components and meet the requirements of multi-head switching. However, disassembling the entire optical path system 5 is quite troublesome and would greatly increase the redundancy of the workflow. Therefore, instead of disassembling and switching the entire system, the emitting head 7 and the optical path system 5 are separated. The optical path system 5 is always connected to the transmission module 3 on the top of the optomechanical processing table 1. A transmission plate 61 for transmitting laser and other media and information is set at the bottom of the optical path system 5, and a docking plate 62 for introducing laser and receiving information media is set at the top of the emitting head 7. The transfer plate 61 and the docking plate 62 are interlocked by grooves, allowing for quick model switching simply by mounting the corresponding transmitter 7 at the bottom of the docking plate 62. During switching, the protruding part of the docking plate 62 to be replaced is first engaged with the inside of the transfer plate 61 to align and initially position the optical path system 5. Then, the electronic telescopic rods 6404 located on the top of the sliding rails 6401 on both sides of the transfer plate 61 are activated, causing them to extend upwards and raise the height of the top lifting block 6405. As the lifting block 6405 rises, the linkage rods 6406 on both sides rotate downwards, simultaneously pulling the connecting arms 6403 located on both sides of the sliding rails 6401. One end of 6403 is connected to a sliding block 6402 slidably connected inside the sliding rail 6401, and the other end is connected to a fixing rod 63 for fixing the docking plate 62. Therefore, after the sliding rail 6401 limits its movement direction, it achieves the effect of simultaneously moving the fixing rods 63 on both sides inward, thus clamping and installing the docking plate 62 from both sides towards the center. During installation, to prevent damage to the docking plate 62 and its internal structure from direct contact with the fixing rods 63, the fixing rods 63 do not directly contact the sides of the docking plate 62. Instead, an elastic element composed of a telescopic column 82 with an embedded compression spring 83 is provided inside the fixing rod 63. This elastic element can completely retract to the inside of the travel groove 81 opened inside the fixing rod 63. An elastic contact plate 84 is provided on the outer side of 82. During the process of the two fixing rods 63 moving inward at the same time, the contact plate 84 first contacts both sides of the docking plate 62, and the elastic material on its surface initially offsets the contact stress. As the fixing rods 63 are further pushed forward, the telescopic column 82 and its internal compression spring 83 gradually retract and generate a push to further offset the corresponding force until the telescopic column 82 is completely retracted into the stroke groove 81 and the fixing rod 63 is in contact with the contact plate 84, thus completing the clamping and fixing, thereby reducing the risk of damage to this fixing method. In addition, to enhance the reinforcement effect, a fixing slot 9 and a fixing block 10 are also provided between the docking plate 62 and the contact plate 84 to achieve further clamping and fixing. In summary, the optical mechanism of the multi-head machining center is optimized.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
