Description

Technical Field

[0001] This utility model relates to a plate drilling device, and more particularly to a plate drilling device that prevents deviation. Background Technology

[0002] In the field of sheet metal processing, drilling is a fundamental and crucial process, widely used in furniture manufacturing, building decoration, electronic device casing processing, automotive interior parts production, and many other industries. Existing sheet metal drilling equipment is mainly divided into two categories based on its level of automation and structural form: manual operation and mechanical fixed operation. Traditional manual operation equipment typically relies on workers holding a drill bit or a small portable drilling device, determining the drilling position manually by visual inspection, marking, or simple measuring tools before drilling. Mechanical fixed operation equipment is usually equipped with a worktable, positioning mechanism, and power-driven drill bit assembly. The sheet metal is placed on the worktable, initially fixed by positioning components or clamping structures, and then the drill bit assembly completes the drilling operation.

[0003] Existing sheet metal drilling devices suffer from several technical defects in practical applications. Among these, the problem of sheet metal or drilling position deviation caused by various factors is particularly prominent, seriously affecting drilling accuracy, processing quality, and production efficiency. When manually operating the drilling tool, workers need to maintain a stable posture for extended periods, resulting in high labor intensity and fatigue. Even slight hand tremors or positioning errors can cause the drilling position to deviate from the preset coordinates. Although traditional devices are equipped with positioning components, their fixing structure design is unreasonable. For example, using fastening bolts inside the positioning components to clamp the sheet metal requires the use of specialized tools such as wrenches to tighten the bolts, increasing the steps of sheet metal installation and removal. In practical applications, fixing each sheet metal takes about 2-3 minutes, reducing positioning efficiency by more than 40% compared to rapid clamping methods, seriously affecting the continuity of overall operations. Furthermore, traditional devices often use single-sided or simple mechanical clamping, resulting in poor adaptability to sheet metal of different thicknesses. Traditional fixing structures cannot be adjusted according to sheet metal thickness, requiring repeated manual adjustments of the clamps, further reducing production efficiency.

The first strap wheel and the second strap wheel are meshed and connected. The outer periphery of the center position of the first strap wheel is connected to the beginning end of the strap, and the outer periphery of the center position of the second strap wheel is connected to the end end of the strap. The strap is wrapped in opposite directions around the outer periphery of the first strap wheel and the second strap wheel, and the center position of the strap is located outside the base.

[0007] Furthermore, it also includes a second motor, which is disposed inside the base and is located below the rotating slot. The second motor is rotatably connected to the rotating rod via a rotating shaft, and is electrically connected to the controller and the battery respectively.

[0008] Furthermore, it also includes a first telescopic rod, which is located at the top of the vertical rod and is perpendicular to the vertical rod. The end of the first telescopic rod is connected to the beginning of the L-shaped fixed rod. The first telescopic rod is electrically connected to the controller and the battery respectively.

[0009] Furthermore, it also includes a second telescopic rod, which is located inside the L-shaped fixed rod and is arranged parallel to the connecting rod. The end of the second telescopic rod is connected to the beginning of the connecting rod, and the second telescopic rod is electrically connected to the controller and the battery respectively.

[0010] Furthermore, it also includes a locking and positioning device, which includes an adjusting gear rotatably mounted on the side wall of the base via a fixed shaft. The beginning of the fixed shaft passes through the adjusting gear and the side wall of the base in sequence and is connected to the adjusting knob. A transmission rod is provided at a position opposite to the adjusting gear, and teeth are provided on the opposite side of the two transmission rods. Both transmission rods are meshed with the adjusting gear through corresponding teeth. A clamping block is provided at the end of each of the two transmission rods. The two clamping blocks are mirror images of each other on both sides of the base. A clamping plate is provided below each of the two clamping blocks. The two clamping plates are movably connected to the corresponding clamping blocks via corresponding adjusting rods. The beginnings of the two adjusting rods pass through the corresponding clamping blocks and are connected to corresponding rotating handles.

[0013] Furthermore, the inner wall of the base is provided with limiting protrusions corresponding to the positions of the two transmission rods, and the multiple limiting protrusions are all L-shaped structures. Each of the two transmission rods is provided with a limiting groove corresponding to the position of the limiting protrusion, and the multiple limiting protrusions are respectively engaged in the corresponding limiting groove.

[0014] Furthermore, a plurality of shock-absorbing vertical plates are provided on the side of the base opposite to the plate, and the shock-absorbing vertical plates are arranged perpendicularly to the base.

[0015] The beneficial effects of this utility model are as follows: 1. This utility model adopts a combination of a base, rotating rod, vertical rod, telescopic crossbar, L-shaped fixing rod, connecting rod, drill motor, connector, and drill bit. This solves the problems of traditional devices often using single-sided or simple mechanical clamping, resulting in poor adaptability to plates of different thicknesses and the inability of traditional fixing structures to adjust according to plate thickness, requiring repeated manual adjustments and reducing production efficiency. In use, first, install the drill bit into the mounting hole of the connector, then snap the vertical rod into the top of the rotating rod to complete the installation. Next, rotate the handle to cause the clamping plate to move downwards, increasing the distance between the clamping plate and the clamping block, thus securing the base to the operating table. Then, rotate the adjustment knob; the adjustment gear will rotate accordingly, driving the transmission rod to move. Since the two transmission rods are positioned above and below the adjustment gear, they will simultaneously move inwards or outwards. The displacement of the two transmission rods is the same because their movement distance is controlled by the adjusting gear. Similarly, the displacement distance of the two clamping blocks is also the same. Through the above technical means, it can be ensured that the base is relatively located at the center of the operating table, which is used to prevent the position of the plate from deviating during subsequent positioning. Stop rotating the adjusting knob when the clamping blocks reach the positions of both sides of the operating table, and push the base towards the operating table so that the bottom surface of the base is completely located on the top surface of the operating table. Then rotate the adjusting knob again to adjust the position of the clamping blocks so that the end of the operating table is in contact with the inner wall of the positioning plate, so that the base is relatively located on the center line of the operating table. Then, by rotating the rotating handle, the clamping plate is displaced upward, thereby clamping the operating table between the clamping plate and the clamping blocks, so that the position of the base is relatively fixed on the operating table, that is, the center position of the base is basically coincident with the center position of the operating table.Then, place the board to be drilled onto the work surface and pull the strap. Because the two ends of the strap are wrapped in opposite directions around the first and second strap wheels, the first and second strap wheels rotate in opposite directions, thus lengthening the exposed portion of the strap until it is fitted around the outer circumference of the board. Then, start the controller to activate the first motor, which drives the power gear. Since the power gear meshes with the first strap wheel, and the first strap wheel meshes with the second strap wheel, the rotation of the power gear simultaneously drives the first and second strap wheels to rotate synchronously, thus wrapping the strap around them and tightening it inwards to secure the board. One side of the board should be close to the base and against the shock-absorbing vertical plate, ensuring the center axis of the board coincides with the center axis of the base. This completes the securing operation of the board. Subsequent operations... The operator inputs the drilling dimensions into the controller, which then controls the second motor to adjust the angle and pushes out the telescopic sleeve via the first telescopic rod, thereby adjusting the position of the L-shaped fixing rod (including the drill bit position). When the drill bit reaches the designated position (i.e., the drilling position input into the controller above), the controller controls the second telescopic rod to extend, bringing the drill bit into contact with the upper surface of the material. The drill motor is then activated to perform the drilling operation, while simultaneously controlling the second telescopic rod to gradually extend, applying a downward force towards the material to complete the drilling operation. This invention employs a wraparound fixing method, adaptable to materials of varying thicknesses, eliminating the need for frequent clamp adjustments, thus improving production efficiency. It effectively reduces offset between the material and the drilling position, enhancing drilling accuracy and processing quality. This invention is relatively easy to operate, effectively reducing the workload of workers, improving the continuity and efficiency of drilling operations, and enhancing its convenience and practicality.

[0016] 2. This utility model employs a combination of a first motor, a drive wheel, a first strapping wheel, a second strapping wheel, and a strap. In use, the board to be drilled is placed on the work surface, and the strap is pulled. Because the two ends of the strap are wrapped in opposite directions around the first and second strapping wheels, the first and second strapping wheels rotate in opposite directions, causing the strap to disengage from them until it is fitted around the outer circumference of the board. Then, the controller is activated, starting the motor, which drives the drive gear to rotate. The drive gear meshes with the first strapping wheel. The first strapping wheel is connected to the second strapping wheel. Therefore, when the power gear rotates, it drives the first and second strapping wheels to rotate synchronously. The strap then wraps around the first and second strapping wheels, tightening the strap inward to fix the plate inside the strap and bringing the plate close to the base and into contact with the shock-absorbing vertical plate. This ensures that the center of the plate basically coincides with the center of the base, completing the plate fixing operation. The operation is relatively simple, effectively reducing the labor burden of workers, improving the continuity and efficiency of drilling operations, and enhancing the convenience and practicality of this utility model.

[0017] 3. This utility model uses a second motor to control the rotation of the rotating rod. During operation, the controller controls the second motor to adjust the angle. As the second motor drives the rotating rod to rotate, it in turn drives the telescopic crossbar to rotate, thereby achieving the purpose of adjusting the angle of the telescopic crossbar. This simplifies the operation steps of adjusting the angle and improves the convenience and practicality of this utility model.

[0018] 4. This utility model connects the first telescopic rod to the L-shaped fixed rod. Since the L-shaped fixed rod is located at the innermost layer of the telescopic crossbar, the innermost telescopic sleeve of the multiple telescopic sleeves sequentially arranged from the outside to the inside of the telescopic crossbar is fitted onto the outer periphery of the starting end of the L-shaped fixed rod, connecting the telescopic crossbar and the L-shaped fixed rod. The position of the L-shaped fixed rod is adjusted by pushing out the telescopic sleeve through the first telescopic rod, which simplifies the operation steps for adjusting the position and improves the convenience and practicality of this utility model.

[0019] 5. This utility model connects the second telescopic rod to the connecting rod, and controls the extension of the second telescopic rod through the controller so that the drill bit contacts the upper surface of the plate. Then the drill motor is started to perform the drilling operation. At the same time, the second telescopic rod is controlled to gradually extend, that is, to apply a downward force towards the plate to complete the drilling operation. This simplifies the drilling operation steps and improves the convenience and practicality of this utility model.

[0020] 6. This utility model uses a snap-fit ​​positioning device to make the base more stable on the work surface and ensure that the base is relatively centered on the work surface. This prevents the position of the board from deviating during subsequent positioning, improves the adaptability of this utility model to boards of different thicknesses, and enhances the convenience and practicality of this utility model.

[0021] 7. By placing the locking and positioning device inside the protective plate, this utility model prevents damage or impact on the locking and positioning device during use, thereby affecting the normal operation of the locking device. This effectively reduces the probability of damage to the locking device, ensures the service life of the locking device, and improves the practicality of this utility model.

[0022] 8. This utility model, by extending a positioning plate downward from the bottom surface of the clamping block, enables the clamping block to better engage with the end of the operating table, and allows the base to be positioned relative to the center line of the operating table, eliminating the need for manual adjustment, simplifying the operation steps, and improving the convenience and practicality of this utility model.

[0023] 9. By combining the limiting protrusion and the limiting groove, this utility model enables both transmission rods to maintain linear movement, ensuring normal movement of the transmission rods and effectively preventing tilting. This extends the service life of the transmission rods and improves the practicality of this utility model while ensuring its normal use.

[0024] 10. This utility model protects the side walls of the base by using multiple shock-absorbing vertical plates, reducing the impact force of the plates on the base when the straps are tightened, extending the service life of the base, and improving the practicality of this utility model.

The outer periphery of the center position of the first strap wheel 13 is connected to the beginning end of the strap 15, and the outer periphery of the center position of the second strap wheel 14 is connected to the end of the strap 15. The strap 15 is wrapped around the outer periphery of the first strap wheel 13 and the second strap wheel 14 in opposite directions, and the center position of the strap 15 is located outside the base 1. A plate 16 is engaged in the strap 15. like Figure 1 , Figure 2 As shown, multiple shock-absorbing vertical plates 38 are provided on the side of the base 1 opposite to the plate 16, and the shock-absorbing vertical plates 38 are arranged perpendicularly to the base 1. like Figure 2 As shown, the telescopic crossbar 4 includes multiple telescopic sleeves 17 arranged sequentially from the outside to the inside, with the innermost telescopic sleeve 17 fitted around the outer periphery of the beginning end of the L-shaped fixed rod 5. like Figure 2 As shown, it also includes a transformer 39 (not shown in the figure), a controller 18, and a battery 19. The transformer 39 is electrically connected to the battery 19, and the controller 18 is electrically connected to the battery 19.

Those skilled in the art will also recognize that, in addition to implementing the controller in purely computer-readable program code form, the same functionality can be achieved by logically programming the method steps to make the controller take the form of logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded microcontrollers. Therefore, such a controller can be considered a hardware component, and the means included therein for implementing various functions can also be considered as structures within the hardware component. Alternatively, the means for implementing various functions can be considered as both software modules implementing the method and structures within the hardware component.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, it also includes a locking and positioning device, which includes an adjusting gear 25 rotatably mounted on the side wall of the base 1 via a fixed shaft. The beginning of the fixed shaft passes through the adjusting gear 25 and the side wall of the base 1 in sequence and is connected to the adjusting knob 26. Transmission rods 27 are provided at positions above and below the adjusting gear 25. Teeth 28 are provided on the opposite side of the two transmission rods 27 and the adjusting gear 25.

[0041] like Figure 2 , Figure 5As shown, the inner wall of the base 1 is provided with limiting protrusions 36 corresponding to the positions of the two transmission rods 27.

The multiple limiting protrusions 36 are respectively engaged in the corresponding limiting grooves 37.

[0042] The materials of the above components will be selected according to the actual use to ensure performance and stability. For different use environments (such as high temperature and humid conditions), it is recommended to prioritize the selection of components with corresponding weather-resistant materials. For details, please refer to the "Environmental Adaptability Parameter Table" manual. The above components should be cleaned, repaired, maintained and replaced in a timely manner in a combination of regular and irregular methods according to the actual usage frequency, operating conditions and other factors to ensure that they are always in good operating condition.

[0043] The specific working principle is as follows: When using it, first install the drill bit into the mounting hole of the connector, and then snap the vertical rod into the top of the rotating rod to complete the installation operation; Then, rotating the handle causes the clamping plate to shift downwards, increasing the distance between the clamping plate and the clamping block. This allows the base to be engaged with the worktable. Next, rotating the adjustment knob causes the adjustment gear to rotate, which in turn moves the transmission rods. Since the two transmission rods are positioned above and below the adjustment gear, they will simultaneously move relative to each other, either inwards or outwards. Because their movement distance is controlled by the adjustment gear, the two transmission rods will move the same distance. Similarly, the two clamping blocks will also move the same distance. This technique ensures that the base is centered on the worktable. To prevent deviations in the plate position during subsequent positioning, stop rotating the adjustment knob when the clamping block reaches the positions on both sides of the worktable. Push the base towards the worktable so that the bottom surface of the base is completely on the top surface of the worktable. Then rotate the adjustment knob again to adjust the position of the clamping block so that the end of the worktable is in contact with the inner wall of the positioning plate and the base is positioned relative to the center line of the worktable. Then, by rotating the handle, the clamping plate is displaced upward, thereby clamping the worktable between the clamping plate and the clamping block, so that the position of the base is relatively fixed on the worktable, that is, the center position of the base is basically coincident with the center position of the worktable. Then, place the board to be drilled onto the work surface and pull the strap. Because the two ends of the strap are wrapped in opposite directions around the first and second strapping wheels, the first and second strapping wheels rotate in opposite directions, thus lengthening the exposed portion of the strap until it is fitted around the outer circumference of the board. Then, start the controller to activate the first motor, which drives the drive gear. Since the drive gear meshes with the first strapping wheel, and the first strapping wheel meshes with the second strapping wheel, the rotation of the drive gear simultaneously drives the first and second strapping wheels to rotate synchronously, thus wrapping the strap around them and tightening it inwards to secure the board. The plate is secured by straps, with one side of the plate close to the base and the shock-absorbing vertical plate. The central axis of the plate is aligned with the central axis of the base, thus securing the plate. The operator then inputs the drilling dimensions into the controller, which controls the second motor to adjust the angle and pushes out the telescopic sleeve via the first telescopic rod. This adjusts the position of the L-shaped fixing rod (including the position of the drill bit). When the drill bit reaches the designated position (the drilling position input into the controller above), the controller extends the second telescopic rod to contact the upper surface of the plate. The drill motor is then started to perform the drilling operation, while the second telescopic rod gradually extends, applying a downward force towards the plate to complete the drilling operation. After drilling is completed, the controller stops the drill motor and shortens the second telescopic rod to disengage the drill bit from the material. Then, the controller shortens the first telescopic rod and starts the second motor to return the drill bit to its initial position. The controller then reverses the direction of the first motor (or the controller stops the first motor and manually stretches the strap to loosen it). The strap is then loosened to make it longer, making it easier to remove the material. After the material is removed, the controller starts the first motor again to tighten the strap, completing the drilling operation.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
