[0084] Embodiment 1:

[0085] As shown in Figure 1 and Figure 2 , the present embodiment provides a vertical drilling machine, comprising:

[0086] a base 1;

[0087] a column 2 arranged on the base 1;

[0088] a workbench 21 arranged on the column 2 for supporting a workpiece;

[0089] a main frame 22 arranged at the upper end of the column 2;

[0090] a transmission shaft 23 rotatably arranged on the main frame 22, and one end of the transmission shaft 23 protrudes out of the main frame 22; a drill bit 24 arranged on the transmission shaft 23;

[0091] a height adjusting mechanism 4 cooperating with the transmission shaft 23 for adjusting the height of the drill bit 24;

[0092] a power mechanism 5 cooperating with the transmission shaft 23 for driving the drill bit 24 to perform drilling work;

[0093] a splash-proof mechanism 3 arranged on the drill bit 24 for blocking debris from splashing;

[0094] The splash-proof mechanism 3 comprises:

[0095] a mounting plate 31 arranged on the main frame 22;

[0096] a fixed block 32 arranged on the outer side of the mounting plate 31;

[0097] a rotating shaft 33 rotatably arranged on the fixed block 32;

[0098] an ear plate 34 arranged at both ends of the rotating shaft 33;

[0099] A fixed cover 35 is arranged between the two ear plates 34;

[0100] A protective cover 36 is arranged inside the fixed cover 35, and the protective cover 36 is in a U shape and surrounds the drill bit 24;

[0101] A waist hole 37 is arranged on both sides of the protective cover 36;

[0102] A fixed hole 38 is arranged on both sides of the fixed cover 35, and the fixed hole 38 is arranged corresponding to the waist hole 37; a fastening bolt 39 is arranged between the fixed hole 38 and the waist hole 37;

[0103] A nut 310 is threadedly arranged on the fastening bolt 39 and fastens the protective cover 36 and the fixed cover 35.

[0104] In the technical solution, the anti-splashing mechanism 3 includes a U-shaped protective cover 36, which can effectively surround the drill bit 24 and prevent the splashing of debris generated during the drilling process to the outside of the drill bit 24. This design can minimize the splashing of debris and effectively block the splashing from harming the workers and equipment. The anti-splashing mechanism 3 can adjust the working height of the drill bit 24 to ensure that the protective cover 36 is always synchronized with the position and movement of the drill bit 24, providing continuous and effective protection. The protective cover 36 and the fixed cover 35 are connected by the fastening bolt 39 and the fixed cover 35, and the nut 310 is designed for fast and easy installation, which can be easily disassembled or replaced. Compared with the traditional fixed protective cover 36, the design of the present application makes the maintenance and replacement of the anti-splashing device more convenient, improving the operation efficiency and maintenance convenience of the equipment.

[0105] Work flow: during the assembly of the vertical drilling machine, first set the mounting plate 31 on the main frame 22, and fix the rotating shaft 33 outside the mounting plate 31 through the fixing block 32; then set the ear plate 34 at both ends of the rotating shaft 33, and install the fixing cover 35 between the ear plates 34 to form the fixed cover 36 structure, fix the cover 36 on the fixing cover 35 through the bolt and nut 310, and ensure that the cover 36 stably surrounds the drill bit 24 and the workpiece to avoid splashing of debris. At this time, the various components of the anti-splashing device are tightly connected, the waist hole 37 outside the cover 36 is aligned with the fixing hole 38 on the fixing cover 35, and it is ensured that the protective cover 36 always maintains the correct position during work. When the vertical drilling machine starts drilling work, the power mechanism 5 drives the transmission shaft 23 to rotate, which drives the drill bit 24 to penetrate into the workpiece. At this time, the debris and mud generated during the operation of the drill bit 24 are effectively blocked by the cover 36, reducing the splashing of debris to the surrounding environment, thereby improving the safety of the work. Before drilling, if it is necessary to correct the drill bit 24, the operator can rotate the cover 36 by ninety degrees, and under the action of the rotating shaft 33, the cover 36 is rotated to not block the line of sight of the drill bit 24. At this time, the height of the drill bit 24 is adjusted through the height adjusting mechanism 4 without worrying about the influence of the cover 36 on the line of sight. Since the position of the cover 36 can be adjusted as needed, the accuracy of the drilling process is ensured. After a long time of use, if the cover 36 is worn or damaged, the bolt and nut 310 can be disassembled to quickly remove the cover 36 from the fixing cover 35 for cleaning, replacement or maintenance. This design simplifies the maintenance process of the equipment and prolongs the service life of the equipment. In this way, the splashing debris during drilling can be effectively blocked without affecting the operating line of sight of the drill bit 24, reducing the potential hazards of splashing debris to workers, equipment and the working environment. Effectively solve the problems of poor durability and inconvenient disassembly and replacement, also improve the convenience of operation and the maintenance efficiency of the equipment, thereby improving the overall work safety and drilling efficiency.

[0106] As Figures 1-3 shown in the embodiment, the optimized height adjusting mechanism 4 includes:

[0107] a bearing 40 arranged on the transmission shaft 23;

[0108] a sleeve 41 arranged outside the bearing 40, the sleeve 41 being located in the main frame 22;

[0109] a tooth groove 42 arranged outside the sleeve 41, the tooth groove 42 having a plurality of tooth grooves uniformly distributed along the length direction of the sleeve 41;

[0110] a rotating rod 43 rotatably arranged on the main frame 22;

[0111] a gear 44 arranged on the rotating rod 43, the teeth on the gear 44 being matched with the tooth grooves 42 on the sleeve 41;

[0112] A pressing rod 45 is arranged at one end of the rotating rod 43.

[0113] A shell 46 is arranged outside the main frame 22, and the rotating shaft 33 penetrates the shell 46.

[0114] A spring 47 is arranged on the rotating rod 43 and inside the shell 46.

[0115] A convex plate 48 is arranged on the sleeve 41, and the convex plate 48 is above the mounting plate 31, used for pushing the shroud 36 to move synchronously with the drill bit 24.

[0116] In the technical solution, when the height of the drill bit 24 needs to be adjusted, the user presses the pressing rod 45, the pressing rod 45 drives the rotating rod 43 to rotate, the spring 47 is deformed, the gear 44 arranged on the rotating rod 43 starts to rotate, the teeth on the gear 44 are engaged with the tooth grooves 42 on the outer side of the sleeve 41, thereby driving the sleeve 41 to move up and down along the main frame 22, the up and down movement of the sleeve 41 drives the height of the entire height adjustment system to change, and finally the lifting of the drill bit 24 is realized, the height of the drill bit 24 is accurately adjusted, and it is ensured that the drill bit 24 is at the required working position. At the same time, the convex plate 48 on the sleeve 41 extrudes the mounting plate 31 to move, the mounting plate 31 drives the entire anti-splashing mechanism 3 to move, so that the shroud 36 can move synchronously with the drill bit 24, to ensure the effective anti-splashing function. After being adjusted to the ideal height, the user can start the drilling operation. After the drilling is completed, the user releases the pressing rod 45, the rotating rod 43 reversely rotates under the resetting action of the spring 47, and drives the gear 44 to reversely rotate, the teeth on the gear 44 are engaged with the tooth grooves 42 on the sleeve 41, thereby driving the sleeve 41 to move upwards, the sleeve 41 drives the drill bit 24 to move upwards to reset, the setting of the tooth grooves 42 makes the engagement between the gear 44 and the sleeve 41 very accurate, avoiding the height instability caused by looseness or slippage, and thus the accurate adjustment of the height of the drill bit 24 is realized, to adapt to the needs of different workpieces.

[0117] As shown in Figure 1 , Figure 3 and Figure 4 , in the embodiment, the optimized power mechanism 5 comprises:

[0118] A machine shell 51 is arranged on the main frame 22.

[0119] A cover body 52 is arranged on the machine shell 51.

[0120] A fixing frame 53 is arranged on the main frame 22.

[0121] A motor 54 is arranged on the fixing frame 53.

[0122] A connecting shaft 55 is arranged on the output shaft of the motor 54.

[0123] The pulley 56 is arranged on the connecting shaft 55 and the transmission shaft 23, and is located inside the casing 51 and the cover 52.

[0124] The transmission belt 57 is sleeved between the two pulleys 56.

[0125] In the technical solution, when the system is powered on, the motor 54 starts to work to generate rotating power. The rotating power output by the motor 54 is transmitted to the pulley 56 on the connecting shaft 55, and the pulley 56 on the connecting shaft 55 cooperates with the pulley 56 on the other end of the transmission shaft 23. The pulley 56 functions to transmit the rotating movement of the connecting shaft 55 to the transmission shaft 23 through the transmission belt 57, and the rotation of the transmission shaft 23 directly drives the drill bit 24 to make the drill bit 24 perform drilling work on the workpiece. The casing 51 and the cover 52 protect the transmission system, ensure the stability and safety of each component during work, provide external protection for the entire power mechanism 5, avoid damage to the key components such as the motor 54 and the pulley 56 caused by the external environment, and ensure the stability of the equipment during operation, so as to realize the drilling work on the workpiece and ensure that the drill bit 24 can work smoothly and efficiently.

[0126] Embodiment 2

[0127] The embodiment provides a vertical drilling machine, in addition to the technical solutions of the above-mentioned embodiments, further having the following technical features.

[0128] As shown in Figure 1 and Figure 4 In this embodiment, the casing 51 and the cover 52 are provided with a locking mechanism 6, and the locking mechanism 6 comprises:

[0129] The fixed plate 61 is arranged on the outside of the casing 51 and the cover 52.

[0130] The through hole 62 is arranged on the fixed plate 61.

[0131] The bolt 63 passes through the two through holes 62 on the same side.

[0132] The handle 64 is arranged on the outside of the cover 52.

[0133] In the technical solution, the main function of the locking mechanism 6 is to ensure that the casing 51 and the cover 52 are tightly combined during use and do not loosen or accidentally fall off, thereby avoiding the safety hazards caused by the loosening of the cover 52 during the operation of the machine. For example, the loosening of the cover 52 may expose the internal components, thereby increasing the risk of mechanical failure or operational danger. It helps to protect the internal power transmission system such as the motor 54 and the pulley 56 from the external environment, such as dust, moisture or foreign matter entering the inside of the equipment, to ensure the normal operation of the equipment. Through the cooperation of the bolt 63 and the fixed plate 61, the unnecessary loosening of the cover 52 due to external impact or vibration during use can be effectively prevented. Through the setting of the handle 64, the user can conveniently fix or release the cover 52 and the casing 51, simplifying the process of disassembling and assembling the cover 52, saving time and manpower.

[0134] Workflow: In the normal working state, the casing 51 and the cover 52 should be tightly combined. The bolt 63 passes through the through hole 62 on the fixed plate 61, so that the fixed plate 61, the casing 51 and the cover 52 are firmly connected together to prevent the cover 52 from loosening or falling off during work; the bolt 63 locks the casing 51 and the cover 52 together to form a stable connection structure. When maintenance or repair of the stand drill is needed, the user can pull out the bolt 63 from the through hole 62 to release the locking state between the casing 51 and the cover 52. Once the bolt 63 is removed, the cover 52 can be easily separated from the casing 51 through the handle 64, and the user can check, clean or perform other maintenance work on the conveying components in the casing 46. When the maintenance work is completed, the user aligns the cover 52 with the casing 51 again and ensures the firm connection between the cover 52 and the casing 51. The user inserts the bolt 63 into the through hole 62 on the fixed plate 61, passes the bolt 63 between the two through holes 62, and locks the cover 52 and the casing 51 to ensure that they are firmly connected and prevent the cover 52 from loosening or falling off during the next use. Once the bolt 63 is fully inserted and locked, the connection between the cover 52 and the casing 51 is fixed. At this time, the connection between the casing 51 and the cover 52 is no longer affected by external forces, ensuring that the stand drill can operate stably during work.

[0135] Example 3:

[0136] The embodiment provides a stand drill, which further has the following technical features in addition to the technical solutions of the above-mentioned embodiments.

[0137] As shown in Figures 1-3 In this embodiment, the main frame 22 is provided with a guide mechanism 7 for moving the drill bit 24. The guide mechanism 7 comprises:

[0138] The support plate 71 is arranged on the outer side of the main frame 22.

[0139] A guide rod 72 is slidingly arranged on the support plate 71.

[0140] A connecting plate 73 is arranged on the mounting plate 31, and the connecting plate 73 is fixedly connected with the guide rod 72.

[0141] In the technical solution, during drilling, the guide mechanism 7 arranged on the main frame 22 provides support for the guide rod 72 through the support plate 71, so that the guide rod 72 remains stable and does not deviate or dislocate. The guide rod 72 is designed to be slidable, and the sliding design enables the guide rod 72 to move freely along the track of the support plate 71 as needed. When the drilling machine is started and begins to drill, the connecting plate 73 is fixedly connected with the guide rod 72, and the movement of the guide rod 72 is linked with the movement of the drill bit 24, which means that the sliding of the guide rod 72 ensures that the drill bit 24 moves stably along the predetermined path vertically or at the required angle. When the drill bit 24 begins to drill, the sliding movement of the guide rod 72 ensures that the drill bit 24 advances stably in the correct direction. If the drilling machine encounters resistance or excessive pressure during drilling, the stability of the guide mechanism 7 still ensures that the drill bit 24 can remain in a stable position. When drilling to the predetermined depth, the guide mechanism 7 will assist the drill bit 24 to retreat and reset, thus achieving accurate guidance of the drill bit 24 and ensuring that the drilling machine can operate stably and accurately during drilling, avoiding deviation of the drill bit 24 from the predetermined track.

[0144] As shown in Figure 1 and Figure 5 In the embodiment, the workbench 21 is provided with a clamping mechanism 8 for clamping workpieces, and the clamping mechanism 8 comprises:

[0145] A support seat 81 is arranged on the workbench 21 and used for supporting workpieces to be drilled;

[0146] A first clamp 82 is arranged at one end of the support seat 81;

[0147] A sliding groove 83 is formed in the support seat 81;

[0148] A screw rod 84 is threadedly arranged on the support seat 81;

[0149] A handle 85 is arranged on the screw rod 84;

[0150] A sliding block 86 is slidingly arranged in the sliding groove 83 and threadedly connected with the screw rod 84;

[0151] The second clamp 87 is arranged on the sliding block 86, and the second clamp 87 is arranged correspondingly with the first clamp 82.

[0152] In the technical solution, the user places the workpiece to be processed on the support seat 81 on the workbench 21, ensures that the basic position of the workpiece is in place, then rotates the handle 85 on the screw rod 84 to rotate the screw rod 84, the rotation of the screw rod 84 drives the sliding block 86 to slide along the sliding groove 83, and then pushes the second clamp 87 to clamp in the direction of the workpiece, until the second clamp 87 is completely slid in place, and the first clamp 82 and the second clamp 87 stably clamp the workpiece. In this process, the screw rod 84 provides sufficient torque required for clamping, so that the clamp stably fixes the workpiece and prevents any displacement of the workpiece during drilling. After clamping is completed, the vertical drilling machine starts drilling work, and the workpiece is clamped firmly and will not be displaced during drilling, ensuring the accuracy and consistency of drilling. After the drilling work is completed, the user reverses the operation of the screw rod 84 by rotating the handle 85 to loosen the clamping mechanism 8 and release the workpiece. At this time, the sliding block 86 moves reversely along the sliding groove 83, the first clamp 82 and the second clamp 87 loosen the workpiece, and the workpiece can be conveniently taken out, so that the workpiece can be stably and accurately fixed during drilling, not only ensuring the processing accuracy, but also improving the operation convenience, adapting to the clamping requirements of different workpieces, and reducing the processing errors caused by the movement or loosening of the workpiece.

[0153] As shown in Figure 1 and Figure 5 In the embodiment, the workbench 21 is provided with a position adjusting mechanism 9 for adjusting the relative position of the support seat 81 and the drill bit 24, and the position adjusting mechanism 9 comprises:

[0154] A guide groove 91 is arranged on both sides of the workbench 21;

[0155] A sliding rod 92 is slidably arranged in the guide groove 91, and the sliding rod 92 is connected with the support seat 81;

[0156] A gas cylinder 93 is arranged on both sides of the bottom of the workbench 21;

[0157] A pull plate 94 is arranged on the piston rod of the gas cylinder 93, and the pull plate 94 is connected with the sliding rod 92.

[0158] In the technical solution, when the relative position of the support seat 81 and the drill bit 24 needs to be adjusted, the user controls the air cylinder 93 to make the piston rod in the air cylinder 93 start to move, and the piston rods on both sides of the air cylinder 93 synchronously push the pull plate 94, the movement of the pull plate 94 drives the slide rod 92 to smoothly slide in the guide groove 91, the movement of the slide rod 92 causes the support seat 81 to change the position, so as to adjust the relative position between the support seat 81 and the drill bit 24. After adjusting to the required position, the air cylinder 93 stops working, and the support seat 81 is in a new accurate position and can stably support the drill bit 24. According to the requirement, the air cylinder 93 will be kept in a fixed position until the next adjustment is needed, and the air cylinder 93 will act again. After the support seat 81 is adjusted to the appropriate position, the user places the workpiece on the support seat 81, clamps it through the first clamp 82 and the second clamp 87, adjusts the relative position between the drill bit 24 and the workpiece under the action of the height adjusting mechanism 4, drives the drill bit 24 to rotate through the power mechanism 5, so as to realize the drilling of the workpiece. In this way, the relative position between the support seat 81 and the drill bit 24 can be efficiently and accurately adjusted, so as to ensure the accuracy and stability of the drilling operation and meet the adjustment requirements under different working conditions.
