Description

Technical Field

[0001] The utility model relates to the field of drilling and milling machines, and more specifically, to a detachable numerical control drilling and milling machine fixing device for long profiles. Background Technique

[0002] A numerical control drilling and milling machine is a numerical control machine tool that combines drilling and milling functions and is mainly used for precision machining of small and medium-sized parts. It has an automatic tool change function and can complete multiple processes in one clamping, such as drilling, reaming, tapping, and milling. However, when the existing drilling and milling machine performs drilling and milling operations on long profiles, the end of the profile will rub against the vertical plate of the extension table during the flipping process, causing wear of the vertical plate and reducing the service life of the device.

[0003] Regarding the above technical problem that when the existing drilling and milling machine performs drilling and milling operations on long profiles, the end of the profile will rub against the vertical plate of the extension table during the flipping process, causing wear of the vertical plate and reducing the service life of the device, after a large number of retrievals, a detachable numerical control drilling and milling machine fixing device for long profiles with the patent publication number of CN214868798U was found, belonging to the field of drilling and milling machines. This device inserts the end of the long profile into the positioning groove of the positioning block and clamps the profile with the clamping plates on both sides. As the profile rotates, it drives the positioning block to slide along the arc groove, keeping the end of the long profile in a relatively fixed state with the positioning block, without rubbing against the positioning vertical plate, ensuring the fixing effect of the profile while ensuring the service life of the device and reducing damage to the end of the profile.

[0004] However, there are still some problems with the above-mentioned detachable numerical control drilling and milling machine fixing device for long profiles. For example, since the extension table of the device cannot rotate relative to the support, it is easy for the profile to rub against the extension table when following the placement table and the positioning vertical plate to rotate, resulting in wear of the profile. To solve the above problems, the utility model proposes a detachable numerical control drilling and milling machine fixing device for long profiles. Content of the Utility Model

Detailed implementation mode

[0028] The following will combine the attached drawings in the embodiments of the present utility model Figures 1-6 to clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0029] Please refer to Figures 1-6 , in the embodiment of the present utility model, a detachable numerical control drill and milling machine fixing device for long profiles includes a machine body 1, fixing plates 3 oppositely arranged on the machine body 1, and a placing table 2 rotatably arranged on the fixing plates 3 through a rotating shaft, an extension plate 4, the top of the first end of which is fixedly connected with a baffle 6, the rotating shaft extends outside the fixing plate 3 and is fixedly connected with a plug rod 7, the plug rod 7 is of a square structure, a slot 12 for the plug rod 7 to insert is arranged through the second end of the extension plate 4, a limiting hole 10 is arranged on the plug rod 7, and a limiting component 8 for limiting the limiting hole 10 is arranged in the extension plate 4.

[0030] Specifically, when the extension plate 4 needs to be used to fix the long profile, the plug rod 7 is inserted into the slot 12 of the extension plate 4. Since the plug rod 7 is of a square structure, its rotation in the slot 12 can be restricted after being inserted into the slot 12, ensuring the stable direction of the extension plate 4. After the plug rod 7 is inserted into the slot 12, the limiting component 8 cooperates with the limiting hole 10 on the plug rod 7 to realize the limiting and fixing of the plug rod 7. The limiting component 8 may be a single or combined structure such as a pin, a threaded rod, a spring 82, etc., and is inserted into the limiting hole 10 in a natural state, or the limiting component 8 is manually operated to enter the limiting hole 10, so as to firmly fix the plug rod 7 in the slot 12; when the extension plate 4 needs to be disassembled, the limiting component 8 is operated to withdraw from the limiting hole 10 of the plug rod 7. Such a design enables the fixing device to conveniently install and disassemble the extension plate 4 when needed to adapt to the processing requirements of long profiles with different lengths. The overall structure is simple, enabling the extension plate 4 to rotate synchronously with the placing table 2, avoiding the wear and consumption of the profiles.

[0031] It should be noted that in this embodiment, the installation and operation of the machine body 1 and the placing table 2 can refer to a detachable numerical control drill and milling machine fixing device for long profiles with a patent publication number of CN214868798U.

[0032] In the embodiment of the present utility model, as Figure 6As shown, the limiting assembly 8 includes a movable plate 83, which is movably arranged in the extension plate 4, and a movable groove 85 is provided in the extension plate 4 for the movable plate 83 to move. A limiting block 84 is fixedly connected to the movable plate 83, and the limiting block 84 is movably arranged in the extension plate 4 relative to the limiting hole 10. A pull rod 81, a first end of which is fixedly connected to an end of the movable plate 83 away from the limiting block 84, and a second end of the pull rod 81 extends to the outside of the extension plate 4, and a spring 82 is sleeved on the pull rod 81 and fixedly connected to the movable plate 83. The spring 82 is located in the movable groove 85. Specifically, when the insertion rod 7 is inserted into the slot 12, the insertion rod 7 Push the limit block 84 to move toward the inside of the movable groove 85, so that the movable plate 83 compresses the spring 82. When the limit hole 10 corresponds to the limit groove, the spring 82 pushes the movable plate 83 to make the limit block 84 insert into the limit hole 10 on the insertion rod 7, so as to limit and fix the insertion rod 7, thereby firmly connecting the extension plate 4 to the rotating shaft. When the extension plate 4 needs to be removed, pull the pull rod 81, and the pull rod 81 drives the movable plate 83 to overcome the elastic force of the spring 82 and move away from the insertion rod 7, so that the limit block 84 withdraws from the limit hole 10. At this time, the insertion rod 7 can be pulled out of the slot 12 to realize the removal of the extension plate 4.

[0033] In the embodiment of the utility model, Figure 3 , Figure 4 and Figure 6 As shown, there are two groups of limit assemblies 8 and limit holes 10, and the two groups of limit assemblies 8 are arranged opposite to each other along the slot 12. A mounting plate 14 is fixedly connected to the bottom of the extension plate 4, and a connecting rod 5 is rotatably connected to the mounting plate 14. The two ends of the connecting rod 5 are respectively hinged with a first connecting rod 13 and a second connecting rod 15, and the ends of the first connecting rod 13 and the second connecting rod 15 facing away from the connecting rod 5 are respectively hinged with the pull rods 81 of the two groups of limit assemblies 8. The connecting rod 5 is an L-shaped structure. Specifically, when one of the pull rods 81 is pulled, the transmission action of the first connecting rod 13, the second connecting rod 15 and the connecting rod 5 can simultaneously drive the other pull rod 81 to move relatively, so that the two limit blocks 84 are simultaneously withdrawn from the limit holes 10, so that the disassembly of the extension plate 4 can be conveniently and quickly realized. It should be noted that the lengths of the first connecting rod 13, the connecting rod 5 and the second connecting rod 15 can be adjusted according to the actual situation of the pull rod 81 to ensure that the two pull rods 81 can operate synchronously.

[0034] In the embodiment of the utility model, Figure 3 and Figure 5As shown, two clamping plates 11 are relatively slidable on the baffle 6, and a driving assembly 9 for driving the two clamping plates 11 to slide relatively is provided in the baffle 6. The driving assembly 9 includes a double-headed screw 93, which is rotatably arranged in the baffle 6. Slide blocks 91 are respectively sleeved and threadedly connected at both ends of the double-headed screw 93. The ends of the two slide blocks 91 away from the double-headed screw 93 are respectively fixedly connected to the two clamping plates 11. A slide groove 92 for the slide blocks 91 to slide is provided in the baffle 6. The end surfaces facing the two clamping plates 11 are fixedly connected with rubber pads 16. The end of the rubber pad 16 away from the clamping plate 11 is paved with anti-slip grooves. 17. Specifically, when it is necessary to clamp and fix the long profile, the double-headed screw 93 is rotated. Since the threads at both ends of the double-headed screw 93 rotate in opposite directions, the two sliders 91 slide relatively in the slide groove 92, thereby driving the two clamping plates 11 to move relative to each other, thereby clamping and fixing the long profile. By adjusting the position of the clamping plate 11, it can adapt to long profiles of different sizes, thereby improving the versatility of the fixing device; the setting of the rubber pad 16 and the anti-slip groove 17 can increase the friction between the clamping plate 11 and the long profile, improve the stability of the clamping, and avoid damage to the surface of the long profile.

[0035] Working principle: When the extension plate 4 is needed to fix the long profile, the insertion rod 7 is inserted into the slot 12 of the extension plate 4. Since the insertion rod 7 is a square structure, its rotation in the slot 12 can be limited after being inserted into the slot 12, ensuring the direction of the extension plate 4 is stable. After the insertion rod 7 is inserted into the slot 12, the limiting component 8 cooperates with the limiting hole 10 on the insertion rod 7 to achieve the limiting fixation of the insertion rod 7. The limiting component 8 may be inserted into the limiting hole 10 in a natural state through a single or combined structure such as a latch, a threaded rod, a spring 82, or the limiting component 8 is manually operated to enter the limiting hole 10, thereby firmly fixing the insertion rod 7. It is fixed firmly in the slot 12. When the long profile needs to be clamped and fixed, the double-headed screw 93 is rotated. Since the threads at both ends of the double-headed screw 93 have opposite rotation directions, the two sliders 91 slide relatively in the slide groove 92, thereby driving the two clamping plates 11 to move relative to each other, and realizing the clamping and fixing of the long profile. When the extension plate 4 needs to be removed, one of the pull rods 81 is pulled. Through the transmission action of the first connecting rod 13, the second connecting rod 15 and the connecting rod 5, the other pull rod 81 can be driven to move relative to each other at the same time, so that the two limit blocks 84 are withdrawn from the limit holes 10 at the same time, and the removal of the extension plate 4 is convenient and quick.
