Description

Technical Field

[0001] This utility model relates to the technical field of drilling and tapping integrated equipment, and in particular to a high-speed drilling and tapping machine with adjustable drilling depth. Background Technology

[0002] A drilling and tapping machine is a machine tool that combines the functions of a drilling machine and a tapping machine. It is fully automatically controlled by CNC equipment and performs a series of processing operations such as automatic feeding, drilling, tapping and unloading of the parts to be processed, thereby achieving the purpose of opening threaded holes in the parts. Due to its high degree of automation, high processing efficiency and high processing accuracy, it has been widely used in the industrial field.

[0003] During the drilling and tapping process, the drill bit drills a hole at a predetermined position and then processes threads on the drilled hole. During the drilling and tapping process, a large amount of heat is generated between the workpiece and the drill bit due to intense cutting friction. Therefore, cutting fluid is continuously sprayed onto the drilling and tapping position to cool and lubricate, so as to ensure the quality of the drilling and tapping process and the safety of the drill bit.

[0004] Chinese utility model patent application number CN202320996055.7 describes a high-speed drilling and tapping machine with adjustable depth. It uses a collection component to collect and filter debris and cutting fluid guided by the upper liquid collection frame during drilling and tapping of the workpiece, preventing the cutting fluid from flowing freely after use and improving the surrounding environment. However, although the aforementioned drilling and tapping machine has a collection component, the cutting fluid splashes when sprayed at the drilling and tapping position, causing some of the cutting fluid to splash outwards and fail to flow smoothly into the collection tank. This results in poor cutting fluid collection and an inability to ensure a clean and tidy environment around the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a high-speed drilling and tapping machine with adjustable drilling depth, in order to solve the problem mentioned in the background art that the existing high-speed drilling and tapping machines with adjustable drilling depth have poor cutting fluid collection effect and cannot ensure the cleanliness of the surrounding environment of the equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-speed drilling and tapping machine with adjustable drilling depth, comprising a base, a lifting assembly on the top of the base, a drilling and tapping device connected to the lifting assembly, a support box fixedly connected to the top of the base, a support plate fixedly connected to the top of the support box, a clamping assembly on the top of the support plate, and a collection assembly for collecting cutting fluid on the support box.

[0007] The collection assembly includes an overflow trough opened on the top of the support plate, and the collection assembly also includes a filter screen connected to the inner side wall of the support box, the filter screen being located directly below the support plate, and the collection assembly also includes four baffles that are rectangularly hinged to the top of the support box.

[0008] Preferably, the collection assembly further includes a pushing mechanism mounted on the support box. The pushing mechanism is used to push the four baffles to rotate up and down. The advantage of this arrangement is that it can automatically push the four baffles to stand upright to block the cutting fluid or push the four baffles to be in a horizontal state to avoid obstructing the clamping or disassembly of the workpiece. It eliminates the need for workers to manually rotate the baffles, thus improving the efficiency of drilling and tapping.

[0009] Preferably, the pushing mechanism includes two sets of first electric telescopic rods symmetrically fixedly connected to the front and rear sides of the support box. A pushing frame is fixedly connected between the output ends of the two sets of first electric telescopic rods. The inner sidewall of the pushing frame is in contact with the outer sidewall of the four baffles. The advantage of this arrangement is that by driving the pushing frame up and down through the first electric telescopic rods, the four baffles can be driven to rotate up and down simultaneously, so that the rotation operation of the baffles is carried out stably and synchronously, ensuring that the cutting fluid can be reliably blocked and ensuring the cleanliness of the environment around the equipment.

[0010] Preferably, there are two filters, which are symmetrically connected between the front and rear inner walls of the support box via two first rotating rods. The system also includes an automatic chip cleaning component mounted on the support box. The advantage of this configuration is that it can automatically collect the chips on the filters, reducing the labor intensity of the workers and preventing them from being scratched by the chips when handling them, thus improving the reliability and safety of the drilling machine.

[0011] Preferably, the automatic chip cleaning assembly includes a sealed door hinged to the right side of the support box, and a collection box placed on the bottom wall of the support box. The side wall of the collection box is hollowed out. The automatic chip cleaning assembly also includes a rotating mechanism on the support box. The rotating mechanism is used to drive the two filters to rotate synchronously downwards. The advantage of this arrangement is that by driving the two filters to rotate synchronously downwards, the chips on the filters can automatically slide into the collection box under the action of gravity. This eliminates the need for workers to manually clean the chips accumulated on the filters, reducing the labor intensity of the workers.

[0012] Preferably, the rotating mechanism includes two pairs of second rotating rods symmetrically rotatably connected to the front and rear sides of the support box. The ends of the two pairs of second rotating rods, close to each other, penetrate the front and rear side walls of the support box and are fixedly connected to the front and rear ends of the two first rotating rods respectively. Two pairs of levers are symmetrically fixedly sleeved on the two pairs of second rotating rods. A torsion spring is fixedly connected between the levers and the side walls of the support box. The rotating mechanism also includes two pairs of moving blocks symmetrically fixedly connected to the bottom of the push frame. Four rows of first push plates are symmetrically fixedly connected to the two pairs of moving blocks. Multiple first push plates in each row are equidistantly distributed along the vertical direction and can all contact the levers. The length of the first push plate gradually decreases from top to bottom. The advantage of this design is that, with multiple first push plates in each group sequentially contacting the deflector, and the length of multiple first push plates in each column gradually decreasing from top to bottom, the deflector can push the filter screen downward to ensure that the cutting chips can fall smoothly into the collection box. At the same time, because there is a gap between two adjacent first push plates, when the first push plate is in the gap, it will rotate upward at a certain angle under the elastic force of the torsion spring. This allows the filter screen to vibrate up and down continuously, which can prevent cutting chips from adhering to the top of the filter screen and not falling down, thus improving the cleaning and collection effect of cutting chips.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. In this utility model, by setting four baffles, by rotating the four baffles to the vertical position, a shield can be formed around the drilling position, thereby effectively blocking the splashing cutting fluid. This allows the cutting fluid to fall onto the filter screen through the overflow groove, so that the cutting fluid is fully and reliably collected, preventing the cutting fluid from splashing around and polluting the environment around the equipment, and ensuring that the environment around the equipment is clean and tidy.

[0015] 2. In this utility model, the automatic chip cleaning component can push the filter screen downward to ensure that the chips fall smoothly into the collection box. At the same time, since there is a gap between the two adjacent first push plates, when the first push plate is in the gap, it will rotate upward at a certain angle under the elastic force of the torsion spring. This makes the filter screen vibrate up and down continuously, which can prevent chips from adhering to the top of the filter screen and not falling down, thus improving the chip cleaning and collection effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Example 1

[0026] Please refer to Figures 1-6The high-speed drilling and tapping machine with adjustable drilling depth shown includes a base 1, a lifting assembly 2 on the top of the base 1, a drilling and tapping device 3 connected to the lifting assembly 2, a support box 4 fixedly connected to the top of the base 1, a support plate 5 fixedly connected to the top of the support box 4, a clamping assembly 51 on the top of the support plate 5, and a collection assembly 6 for collecting cutting fluid on the support box 4.

[0027] The collection assembly 6 includes an overflow trough 61 opened on the top of the support plate 5, and the collection assembly 6 also includes a filter screen 62 connected to the inner side wall of the support box 4. The filter screen 62 is located directly below the support plate 5. The collection assembly 6 also includes four baffles 63 that are rectangularly hinged to the top of the support box 4.

[0028] The lifting assembly 2 includes two pairs of slide rods 21 symmetrically fixedly connected to the top of the base 1. Fixed plates 22 are fixedly sleeved on the two rear pairs of slide rods 21. Moving plates 23 are movably connected to the two front slide rods 21. Drilling equipment 3 is fixedly connected to the front of the moving plate 23. The lifting assembly 2 also includes a drive mechanism 24 disposed between the fixed plate 22 and the moving plate 23.

[0029] The drive mechanism 24 includes a first motor 241 fixedly connected to the front of the fixed plate 22, and a gear 242 fixedly connected to the output end of the first motor 241. The drive mechanism 24 also includes a rack 243 fixedly connected to the back of the movable plate 23, and the rack 243 and the gear 242 mesh with each other.

[0030] refer to Figures 1-5 The collecting component 6 also includes a pushing mechanism 64 provided on the support box 4, which is used to push the four baffles 63 to rotate up and down.

[0031] Specifically, it can automatically push the four baffles 63 to stand upright to block the cutting fluid or push the four baffles 63 to be in a horizontal state to avoid obstructing the clamping or disassembly of the workpiece, without requiring the operator to manually rotate the baffles 63, thus improving the efficiency of drilling and tapping.

[0032] refer to Figure 1 and Figure 2 The pushing mechanism 64 includes two sets of first electric telescopic rods 641 symmetrically fixedly connected to the front and rear sides of the support box 4. A pushing frame 642 is fixedly connected between the output ends of the two sets of first electric telescopic rods 641. The inner side wall of the pushing frame 642 is in contact with the outer side of the four baffles 63.

[0033] Specifically, the first electric telescopic rod 641 drives the push frame 642 to move up and down, which in turn drives the four baffles 63 to rotate up and down. This ensures that the rotation of the baffles 63 is stable and synchronized, reliably blocking the cutting fluid and keeping the surrounding environment of the equipment clean and tidy.

[0034] refer to Figure 4 The number of filters 62 is two. The two filters 62 are symmetrically connected between the front and rear inner walls of the support box 4 through two first rotating rods. The automatic chip cleaning component 8 is also provided on the support box 4.

[0035] Specifically, it can automatically collect cutting chips on the filter 62, reducing the labor intensity of workers and preventing workers from being scratched by cutting chips when handling them, thus improving the reliability and safety of the drilling machine.

[0036] refer to Figures 2-5 The automatic chip cleaning assembly 8 includes a sealed door hinged to the right side of the support box 4. The automatic chip cleaning assembly 8 also includes a collection box 81 placed on the inner bottom wall of the support box 4. The side wall of the collection box 81 is hollowed out. The automatic chip cleaning assembly 8 also includes a rotating mechanism 82 provided on the support box 4. The rotating mechanism 82 is used to drive the two filters 62 to rotate downward synchronously.

[0037] Specifically, by rotating the two filter screens 62 synchronously downwards through the rotating mechanism 82, the cutting chips on the filter screens 62 can automatically slide into the collection box 81 under the action of gravity. This eliminates the need for staff to manually clean the cutting chips accumulated on the filter screens 62, thus reducing the labor intensity of the staff.

[0038] refer to Figures 2-5 The rotating mechanism 82 includes two pairs of second rotating rods 821 symmetrically rotatably connected to the front and rear sides of the support box 4. The ends of the two pairs of second rotating rods 821 that are close to each other pass through the front and rear side walls of the support box 4 and are fixedly connected to the front and rear ends of the two first rotating rods respectively. Two pairs of lever plates 822 are symmetrically fixedly sleeved on the two pairs of second rotating rods 821. Torsion springs 823 are fixedly connected between the lever plates 822 and the side walls of the support box 4. The rotating mechanism 82 also includes two pairs of moving blocks 824 symmetrically fixedly connected to the bottom of the push frame 642. The two pairs of moving blocks 824 are symmetrically fixedly connected to four rows of first push plates 825. Multiple first push plates 825 in each row are equidistantly distributed along the vertical direction and can all touch the lever plates 822. The length of multiple first push plates 825 in each row gradually decreases from top to bottom.

[0039] Specifically, each group of multiple first push plates 825 sequentially contacts the deflector plate 822, and the length of each column of multiple first push plates 825 gradually decreases from top to bottom. In this way, the deflector plate 822 pushes the filter screen 62 downward to ensure that the cutting chips can fall smoothly into the collection box 81. At the same time, since there is a gap between two adjacent first push plates 825, when the first push plate 825 is in the gap, it will rotate upward at a certain angle under the elastic force of the torsion spring 823. This allows the filter screen 62 to vibrate up and down continuously, which can prevent cutting chips from adhering to the top of the filter screen 62 and not falling down, thus improving the cleaning and collection effect of cutting chips.

[0040] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
