Description

Technical Field

[0001] This utility model relates to a punching device. Background Technology

[0002] Currently, drilling equipment plays an important role in the processing and construction fields. Large machine tool-type drilling equipment is usually installed in processing workshops and is suitable for large-scale, high-precision workpiece processing. Its advantages lie in its strong stability and high processing accuracy, but it lacks flexibility and cannot meet the needs of outdoor and variable scenarios.

[0003] Meanwhile, small portable drilling rigs, especially handheld ones, are widely used in diverse situations such as outdoor construction due to their ease of carrying and movement. However, handheld drilling rigs have significant drawbacks in actual operation. On the one hand, it is difficult to accurately control the drilling depth, easily leading to over-drilling or insufficient drilling depth. On the other hand, ensuring the verticality of the drill hole is also quite challenging, requiring a high level of experience from the operator. Inexperienced personnel cannot guarantee drilling quality, and even experienced personnel are easily affected by interference in complex environments, leading to errors. Although additional straightening tools can be used to improve this, it undoubtedly increases the complexity and inconvenience of operation. Given the above, many ordinary people lacking professional knowledge and operating experience face significant difficulties when facing drilling needs. Therefore, it is necessary to design a drilling device that is easy for beginners to operate, thereby improving the ease of use and accuracy of drilling. Utility Model Content

[0004] In order to overcome the shortcomings of the above-mentioned background technology, the present invention provides a punching device that is simple to operate and easy to use.

[0005] The technical implementation scheme of this utility model is as follows: a drilling device includes a base plate, two vertical shafts are vertically arranged on the upper end of the base plate, and mounting plates are slidably arranged on the two vertical shafts. A conversion head is arranged on the mounting plate. A drilling machine is quickly connected to the upper end of the conversion head, and a drill bit is quickly connected to the lower end. A limit ring is provided on one of the vertical shafts to limit the descent height of the mounting plate, and a spring is provided on the other vertical shaft. A vertical hole is opened on the base plate to allow the drill bit to pass through. An extension part is provided on one side of the base plate. The extension part includes a horizontal shaft arranged horizontally on one side of the base plate and a slider slidably connected to the horizontal shaft. A telescopic limit plate is provided on the slider.

[0006] More preferably, distance scales are provided on the vertical axis and the horizontal axis respectively.

[0007] More preferably, the bottom of the slider has a receiving cavity, the top wall of the receiving cavity has a vertically penetrating pin hole, the telescopic limiting plate is disposed in the receiving cavity, and the upper end of the telescopic limiting plate is provided with a pin shaft that slides with the pin hole. A preload spring is sleeved on the pin shaft, the upper end of the preload spring abuts against the top wall of the receiving cavity, and the lower end abuts against the telescopic limiting plate.

[0008] More preferably, the base plate is provided with a receiving hole that slides with the horizontal axis, the receiving hole near the slider is formed into a stepped hole structure, and the horizontal axis away from the slider is provided with a sleeve.

[0009] More preferably, the base plate has two split holes, which are centrally symmetrical about the projection point of the drill bit on the upper surface of the base plate, and limit posts are provided in the two split holes respectively.

[0010] More preferably, the upper surface of the base plate is provided with a V-shaped groove, and the vertical extension line of the drill bit intersects with the V-shaped groove.

[0011] More preferably, the limiting ring includes a limiting ring body, on which a horizontal threaded hole penetrating its side wall is provided, and a locking adjustment rod is internally threaded into the horizontal threaded hole.

[0012] This utility model has the following advantages: 1. The drilling device can accurately control the drilling depth by adjusting the height of the limiting ring, avoiding drilling too deep or too shallow; the base plate abuts against the workpiece, which can effectively ensure the verticality of the drilling and reduce errors; adjusting the distance between the slider and the horizontal axis can flexibly change the distance between the pre-drilling position and the edge of the workpiece to meet different drilling position requirements; the spring on the vertical axis can assist the mounting plate in resetting, making the drilling process smoother and more stable. The overall design greatly reduces the difficulty of operation, allowing even novices to quickly get started and perform accurate drilling.

[0013] 2. The vertical and horizontal axes of the drilling device are respectively equipped with distance scales, which facilitates precise control when adjusting the drilling depth and drilling position, thereby improving drilling accuracy and consistency.

[0014] 3. The storage hole on the base plate of the punching device matches the horizontal shaft, allowing the horizontal shaft to be retracted when the extension part is not in use, reducing the size of the device and making it convenient to carry and store.

[0015] In addition, the symmetrical center holes and limiting posts on the base plate can quickly locate the center point during drilling, ensuring that the drill bit is accurately aligned with the center of the workpiece, improving drilling accuracy and efficiency, and reducing errors caused by positional offset.

[0016] 5. The V-groove of the base plate of the drilling device and its intersection with the vertical extension line of the drill bit provide stable support and limit for the rod-shaped workpiece, preventing the workpiece from rolling or shifting when drilling on its surface, and ensuring a stable and accurate drilling process.

Detailed Implementation

[0023] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0024] like Figure 1-5The drilling device shown includes a base plate 1, a drill 41, and an extension section. The upper end of the base plate 1 has two vertical shafts 2, and a mounting plate 3 is provided on both shafts 2. The mounting plate 3 has two sliding holes that are adapted to the shafts 2 and are slidably connected to the shafts 2. A conversion head 4 is provided at one end of the mounting plate 3. The upper end of the conversion head 4 is used to connect to the drill 41, and the lower end is used to connect to the drill bit 42. The conversion head 4 is quickly detached from the drill 41 and the drill bit 42, respectively, using a quick-release bayonet connection, which can be disassembled and replaced at any time. The base plate 1 has a vertical hole 11 that allows the drill bit 42 to pass through. All surfaces of the base plate 1 are flat and smooth. When drilling, the workpiece is placed against the upper surface of the base plate 1, or the bottom surface of the base plate 1 is placed against the workpiece. This can maintain the verticality of the drilling and reduce errors. In addition, an extension part is provided on one side of the base plate 1. The extension part includes a horizontal axis 7, a slider 8, and a telescopic limiting plate 9. The horizontal axis 7 is horizontally set on one side of the base plate 1, the slider 8 is slidably set on the horizontal axis 7, and the telescopic limiting plate 9 is slidably set on the slider 8. The main function of the extension part is to measure or limit the distance between the drilling position and the side of the workpiece.

[0025] One of the vertical axes 2 is equipped with a limit ring 5, which is used to limit the descent height of the drill bit 42, such as... Figure 3 As shown, in a specific embodiment, the limiting ring 5 includes a limiting ring body 51. The limiting ring body 51 has a horizontal threaded hole 52 that penetrates its side wall, and a locking adjustment rod 53 is internally threaded into the horizontal threaded hole 52. The limiting ring body 51 can be locked at a certain position on the vertical axis 2 by the locking adjustment rod 53. At this time, the minimum height of the mounting plate 3 will be locked, and the depth that the drill bit 42 can drill when the drill 41 is used for drilling will also be locked. Furthermore, there is a distance scale 10 on the vertical axis 2. By observing the corresponding position of the limiting ring body 51 and the distance scale 10, the drilling depth of the drill bit 42 can be precisely controlled.

[0026] In addition, a spring 6 is provided on another vertical shaft 2. The spring 6 is sleeved on the vertical shaft 2, with its lower end abutting against the base plate 1 and its upper end abutting against the mounting plate 3. The spring 6 can apply an upward elastic force to the mounting plate 3 to assist the mounting plate in resetting. The drilling process is made smoother and more stable by setting the spring 6.

[0027] In one specific embodiment, reference Figure 1 and Figure 2The device comprises two parallel horizontal shafts 7. Two parallel storage holes 12 are provided on the side of the base plate 1. The two horizontal shafts 7 are slidably disposed in the two parallel storage holes 12. The slider 8 also has two horizontal holes, and is slidably fitted onto the two horizontal shafts 7 through these holes. A receiving cavity 81 is provided at the bottom of the slider 8. A vertically penetrating pin hole 82 is provided on the top wall of the receiving cavity 81. A telescopic limiting plate 9 is slidably disposed in the receiving cavity 81, and a pin 91 is provided at the upper end of the telescopic limiting plate 9, which slides with the pin hole 82. A preload spring 92 is fitted on the pin 91, with its upper end abutting against the top wall of the receiving cavity 81 and its lower end abutting against the telescopic limiting plate 9. When using the extension section, the horizontal shafts 7 can extend from the storage holes 12; when not in use, the horizontal shafts 7 can be retracted into the storage holes 12. Figure 4 The diagram shows the structure in its stowed state. It is compact, easy to use and carry. In addition, in order to prevent the horizontal axis 7 from easily separating from the storage hole 12, the end of the storage hole 12 near the slider 8 is set as a stepped hole, and a sleeve 71 is fixed to the end of the horizontal axis 7 away from the slider 8. The radius of the sleeve 71 is adapted to the storage hole 12, and the radius of the horizontal axis 7 is slightly smaller than the radius of the storage hole 12. In addition, a threaded hole with an axial extension is provided on the end of the horizontal axis 7 opposite to the sleeve 71, and a large-head screw is installed at the threaded hole. Its function is to prevent the slider 8 from separating from the horizontal axis 7.

[0028] Additionally, it should be noted that a longitudinal threaded hole 84 is provided on one side of the slider 8. This longitudinal threaded hole 84 communicates with one of the horizontal holes 83 on the slider 8, and a locking screw 85 is provided in the longitudinal threaded hole 84. The locking screw 85 abuts against the horizontal axis 7 in the horizontal hole 83, thereby locking the slider 8. In this way, when using the extension part for auxiliary drilling, the position of the drilling point from the edge of the workpiece can be locked. Similarly, a distance scale 10 is also provided on the horizontal axis 7 to facilitate precise drilling point positioning.

[0029] like Figure 5 As shown, when in use, pull out the horizontal axis 7 to its maximum extension, hook the telescopic limiting plate 9 onto the edge of the workpiece a, drag the base plate 1 to the pre-drilling position, lock the drilling point with reference to the distance scale 10 on the horizontal axis 7, and then rotate the locking screw 85 to lock the slider 8. At this time, the distance between the drilling point and the edge of the workpiece will be fixed. Afterwards, when drilling in other positions, simply move the device.

[0030] In a preferred embodiment, the lower end of the pin 91 is provided with an external thread, and the top of the telescopic limiting plate 9 is provided with a vertical threaded hole 93. The pin 91 and the telescopic limiting plate 9 are connected by a threaded hole. By adjusting the length of the pin 91 in the vertical threaded hole 93, the extension length of the telescopic limiting plate 9 in the receiving cavity 81 can be adjusted.

[0031] Furthermore, two center-splitting holes 13 are formed on the base plate 1. The two center-splitting holes 13 are centrally symmetrical about the projection point of the drill bit 42 on the upper surface of the base plate 1, and each of the two center-splitting holes 13 is provided with a limiting post 14. The limiting post 14 can be installed at the upper end of the center-splitting hole 13 or at the lower end of the center-splitting hole 13. By setting the center-splitting holes 13 and the limiting posts 14, the plate can be centered. Figure 5 In the process, a hole is drilled in workpiece b. Workpiece b is placed between two limiting posts 14 and rotated so that it abuts against the inner side of the two limiting posts 14, which allows for quick centering. In addition, a V-shaped groove 15 is provided on the upper end face of the base plate 1. The vertical extension line of the drill bit 42 intersects the V-shaped groove 15. When drilling holes in the surface of the rod-shaped structure, it can be placed in the V-shaped groove 15 for restraint to prevent lateral displacement during drilling.

[0032] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the inventive concept, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
