Description

Technical Field

[0001] This utility model relates to an auxiliary clamping mechanism, and more particularly to an auxiliary clamping mechanism for a drilling machine. Background Technology

[0002] A drilling machine is a general term for machinery and equipment that uses a tool harder and sharper than the target object to leave cylindrical holes or openings in the target object through rotary cutting or rotary extrusion. It is also called a drilling rig, hole punch, borer, or through-hole machine. By drilling precision parts to achieve the desired effect, drilling machines are available in semi-automatic and fully automatic versions. With increasing labor costs, most companies are considering fully automatic drilling machines as their development direction.

[0003] Currently, the most common drilling method using drilling machines involves cutting the material with a high-speed rotating drill bit. The drill bit typically has a helical cutting edge, which not only aids the cutting process but also removes chips generated during drilling. However, during drilling, the workpiece needs to be secured to ensure its stability and positional accuracy. Many standard drilling machines are not equipped with a dedicated mechanism for securing the workpiece. If the workpiece is not properly secured, inaccurate positioning may occur. Without a suitable clamping device, the workpiece may not be fixed in the correct position, affecting drilling accuracy. If the workpiece moves or shifts during processing, the drilled hole will deviate from the intended position. Furthermore, under the drilling force, the workpiece may slide or fly out, posing a potential safety threat to the operator.

[0004] Therefore, it is necessary to design an auxiliary clamping mechanism for drilling machines to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of many standard drilling machines that lack a dedicated fixing mechanism, which is necessary to fix the workpiece during the drilling process to ensure stability and accuracy, if the workpiece is not properly fixed, it may lead to inaccurate positioning, hole deviation, or the workpiece sliding or flying out under the action of drilling force, posing a safety threat to the operator. The technical problem of this utility model is to provide an auxiliary clamping mechanism for drilling machines.

[0006] The technical implementation scheme of this utility model is as follows: an auxiliary clamping mechanism for a drilling machine, comprising a mounting frame, an electric slide rail, a slider, a connecting rod, a mounting plate, a fixing block, a moving block, an elastic element, a rack, a guide rod, a bidirectional screw, a gear, and a clamping block. The mounting frame is mounted on the frame of the drilling equipment. The electric slide rail is fixedly connected to the upper part of the mounting frame. The slider is slidably connected to the electric slide rail. The connecting rod is fixedly connected to the front part of the slider. The mounting plate is fixedly connected to one end of the connecting rod. The fixing block is fixedly connected to the rear part of the connecting rod. Two columns are fixedly provided at the bottom of the fixing block. The movable block is slidably connected between the two columns. The elastic element is symmetrically connected between the slider and the fixed block. Both elastic elements are wound around the corresponding columns. The rack is fixedly connected to the bottom of the movable block. The guide rod is fixedly connected to the top of the mounting frame. The bidirectional screw is rotatably connected to one side of the top of the mounting frame. The gear is fixedly connected to the bidirectional screw. The gear meshes with the rack. The clamping blocks are symmetrically connected between the bidirectional screw and the guide rod. The two clamping blocks are threadedly connected to the bidirectional screw. The two clamping blocks are slidably connected to the guide rod.

[0007] More preferably, it also includes anti-slip plates, with the anti-slip plates fixedly connected to one side of each of the two clamping blocks.

[0008] More preferably, both anti-slip plates have a toothed shape on one side.

[0009] More preferably, it also includes support rods, receiving frames, air pumps, conveying pipes, collecting cylinders, and sealing doors. The support rods are symmetrically fixedly connected to both sides of the top of the mounting frame. The receiving frames are fixedly connected between two support rods on the same side. Multiple material passage holes are linearly arrayed on one side of the two receiving frames. The conveying pipes are connected and communicate with one side of each of the two receiving frames. The air pump is connected and communicated with one side of each of the two conveying pipes. The collecting cylinders are connected and communicated with the bottom of each of the two conveying pipes. The two collecting cylinders are made of breathable material and are fixedly connected to the mounting frame. The sealing doors are rotatably connected to one side of each of the two collecting cylinders.

[0010] More preferably, it also includes a collection frame and a pull rope. The mounting frame has a circular hole in the middle, the mounting plate is located above the circular hole of the mounting frame, the collection frame is placed in the circular hole, and the pull rope is symmetrically fixedly connected inside the collection frame.

[0011] More preferably, it also includes a protective shell, on the top of the mounting bracket, a protective shell for preventing debris generated during drilling from getting stuck at the connection between the gear and the rack, the gear being located inside the protective shell, the bidirectional screw penetrating the protective shell and being rotatably connected to the protective shell, the rack sliding inside the protective shell, and the slider engaging with the protective shell.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention uses an electric slide rail to drive the slider to move, which in turn drives the rack to rotate the gear. Under the action of the gear, the bidirectional screw drives the clamping block to clamp the workpiece, ensuring that the workpiece remains stable during the drilling process and preventing deviation, thereby improving the accuracy of the drilling position. The anti-slip plate design can effectively fix the workpiece and prevent it from sliding or flying out under the action of drilling force, ensuring the safety of the operator. The stable workpiece can reduce unnecessary wear of the drill bit and extend the service life of the tool.

[0013] 2. This utility model uses an air pump to draw the generated waste chips into a collection cylinder, thereby timely cleaning the waste chips and preventing them from accumulating in the drilling area, thus avoiding affecting the drilling quality and the smoothness of the holes. Timely removal of waste chips can reduce the time interrupted by cleaning, improve the ability to operate continuously, prevent chips from entering the equipment, reduce damage to the equipment, and extend the equipment's lifespan.

[0014] 3. This utility model uses a collection frame to collect waste material from the surface of the mounting frame after drilling, thereby providing a clean and flat surface for the next workpiece, ensuring the consistency and stability of each drilling, and centralized collection of waste material can reduce cleaning time and make the operation more efficient.

[0020] 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.

[0021] Example: An auxiliary clamping mechanism for a drilling machine, such as Figures 1-4 As shown, the equipment includes a mounting frame 1, an electric slide rail 2, a slider 3, a connecting rod 4, a mounting plate 5, a fixing block 6, a moving block 7, an elastic element 8, a rack 9, a guide rod 10, a double-acting screw 11, a gear 12, a clamping block 13, and an anti-slip plate 14. The mounting frame 1 is mounted on the frame of the drilling equipment. The electric slide rail 2 is screwed onto the upper part of the mounting frame 1. The slider 3 is slidably connected to the electric slide rail 2. The connecting rod 4 is welded to the front side of the slider 3. The mounting plate 5 is welded to the end of the connecting rod 4 away from the slider 3. The fixing block 6 is welded to the rear part of the connecting rod 4. Two columns are welded to the bottom of the fixing block 6. The moving block 7 is slidably connected between the two columns of the fixing block 6. The elastic elements 8 are symmetrically connected between the fixed block 6 and the movable block 3. The two elastic elements 8 are wound around the corresponding columns. The bottom of the movable block 7 is connected to the rack 9 by welding. The top front side of the mounting frame 1 is connected to the guide rod 10 by welding. The top rear side of the mounting frame 1 is rotatably connected to the bidirectional screw 11. The gear 12 is connected to the bidirectional screw 11 by welding. The gear 12 meshes with the rack 9. The clamping blocks 13 are symmetrically connected between the bidirectional screw 11 and the guide rod 10. The two clamping blocks 13 are threaded to the bidirectional screw 11 and slidably connected to the guide rod 10. The anti-slip plates 14 are connected to the sides of the two clamping blocks 13 that are close to each other by welding. The sides of the two anti-slip plates 14 that are close to each other are toothed.

[0022] When the device is needed, first fix the mounting bracket 1 to the frame of the drilling equipment, then install the drilling machine on the mounting plate 5. The operator then places the workpiece on the mounting bracket 1, starts the electric slide rail 2, and drives the slider 3 to descend. The slider 3 moves the fixed block 6 and the mounting plate 5 downwards together. Simultaneously, the operator starts the drilling machine. As the fixed block 6 descends, the moving block 7 is driven, and the rack 9 descends accordingly. Because the rack 9 meshes with the gear 12, the gear 12 rotates clockwise, thereby driving the double-acting screw 11 to rotate clockwise, causing the clamping blocks 13 on both sides to move closer together until the anti-slip plate 14 contacts and clamps the workpiece. At this point, the slider 3 stops descending, the fixed block 6 continues to move downwards, compressing the elastic element 8, and the drill bit opens. When the workpiece is first contacted and drilling begins, the anti-slip plate 14, with its toothed design, effectively prevents the workpiece from shifting. After drilling is completed, the operator drives the slider 3 upward via the electric slide rail 2. The connecting rod 4 and the fixing block 6 move upward accordingly, and the elastic element 8 gradually resets. When the slider 3 rises to a certain distance, the elastic element 8 fully resets, and the slider 3 continues to rise. The fixing block 6 pulls the moving block 7 upward, and the rack 9 rises accordingly. The gear 12 rotates counterclockwise, and the bidirectional screw 11 rotates in the opposite direction. The clamping blocks 13 on both sides move away from each other, releasing the workpiece. When the slider 3 reaches the end of the electric slide rail 2, the electric slide rail 2 is turned off, and the clamping blocks 13 return to their original positions. The workpiece is now unclamped and can be removed. If drilling is required again, the above steps can be repeated.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes support rods 15, receiving frames 16, air pumps 17, conveying pipes 18, collecting cylinders 19, sealing doors 20, collecting frames 21, and pull ropes 22. The support rods 15 are symmetrically mounted on the front and rear sides of the top of the mounting frame 1 using screws. The receiving frames 16 are mounted between two support rods 15 on the same side using screws. Multiple material passage holes are linearly arranged on the side of the two receiving frames 16 that are close to each other. The sides of the two receiving frames 16 that are far apart from each other are connected to and communicate with the conveying pipes 18. The two conveying pipes 18... The air pump 17 is connected to and communicates with the two conveying pipes 18. The bottom of the two conveying pipes 18 is connected to and communicates with the collection cylinder 19. The two collection cylinders 19 are made of breathable material and are welded to the mounting frame 1. The sealing door 20 is rotatably connected to the side of the two collection cylinders 19 that is far away from each other. A round hole is opened in the middle of the mounting frame 1. The mounting plate 5 is located directly above the round hole of the mounting frame 1. The collection frame 21 is placed in the round hole. The pull rope 22 is symmetrically fixedly connected to the upper part of the collection frame 21.

[0024] like Figure 1As shown, it also includes a protective shell 23. The top rear side of the mounting bracket 1 is fixedly connected to the protective shell 23 to prevent the waste generated during drilling from getting stuck at the connection between the gear 12 and the rack 9. The gear 12 is located inside the protective shell 23. The bidirectional screw 11 passes through the protective shell 23 and is rotatably connected to the protective shell 23. The rack 9 slides inside the protective shell 23. The slider 3 contacts and engages with the protective shell 23.

[0025] To prevent the waste generated during drilling from affecting the drilling effect, the operator can start the air pump 17 during drilling. The waste is sucked into the receiving frame 16 by the airflow generated by the air pump 17, and then enters the collection cylinder 19 through the conveying pipe 18 and the air pump 17. When the waste in the collection cylinder 19 reaches three-quarters of its capacity, the operator can open the sealing door 20 to clean the waste. After cleaning, the sealing door 20 is closed. After drilling is completed, the air pump 17 is turned off and the workpiece is taken out. If there is residual waste on the surface of the mounting frame 1, it may affect the placement stability of the next workpiece. Therefore, the operator should sweep this waste into the collection frame 21. When the collection frame 21 is full, it is pulled out by the pull rope 22, the waste is poured into the waste bucket, and then the collection frame 21 is put back in its original position.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
