Description

Technical Field

[0001] This application relates to the field of positioning ruler technology, and more specifically, to a positioning ruler that can assist in manual drilling. Background Technology

[0002] When drilling holes in components, the drilling positions need to be marked on the components first. The drilling positions are generally obtained by measurement. When marking, the staff needs to use a ruler or other tools to measure the drilling positions and then mark them with a marking pen. Since the marking pen can usually only mark the drilling points, it cannot visually mark the size and range of the drilling on the board. It is also impossible to mark the drilling range according to the distance between the drilling drill bits. This can easily lead to the drilling size being too large or too small after drilling is completed. At the same time, manual drilling is done by manually holding an electric drill, which can easily cause the hole to be crooked and it is not easy to control the drilling depth.

[0003] Therefore, a positioning ruler that can assist in manual drilling is needed to solve the above problems. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a positioning ruler that assists in manual drilling, comprising: a ruler having two mutually perpendicular parts, each with a sliding part that slides in cooperation with the ruler; a limiting plate fixedly disposed at one end of the ruler for abutting against the side of the part to be drilled; a positioning screw threaded onto the sliding part, one end of which abuts against the ruler for positioning; an annular part fixedly connected to the two sliding parts; an annular groove formed on the annular part and coaxially disposed with the annular part; a sliding block slidably disposed within the annular groove; an adjusting rod passing through the sliding block and slidingly cooperating with the sliding block, the sliding direction of the adjusting rod pointing towards the axis of the annular part; a limiting screw threaded onto the sliding block, one end of which abuts against the adjusting rod for positioning; and a marking pen disposed at one end of the adjusting rod.

[0006] By using the sliding part and the annular part, the sliding part is slid to the predetermined scale position of the ruler. The ruler is used to measure the drilled part, and the annular part is adjusted to the drilling position. At this time, the drilling position is marked by the annular groove, the sliding block, and the marking pen. The marking range of the marking pen can be adjusted by the adjusting rod. The size of the hole drilled on the part can be marked for different sizes of drill bits, which makes it easy to observe the drilling range.

[0007] Furthermore, a hinge portion is fixedly provided on the annular portion, and a connecting ring is hinged to the hinge portion. The connecting ring is folded around the axis of the hinge portion, so that the connecting ring has a first state parallel to the upper end face of the annular portion and a second state perpendicular to the upper end face of the annular portion. A positioning ring is slidably provided on the connecting ring. When the connecting ring is in the first state, the positioning ring is coaxial with the annular portion.

[0008] By using the connecting ring, the ring can be adjusted to the second state during marking to avoid obstructing the marking pen. After marking is completed, the marking pen can be moved to the position furthest from the central axis of the ring by adjusting the lever. At this time, the connecting ring is deflected from the second state to the first state.

[0009] Furthermore, a threaded rod is fixedly connected to the hinge, the threaded rod passes through the positioning ring and guides the positioning ring, and a threaded sleeve located between the connecting ring and the positioning ring is threadedly connected to the threaded rod.

[0010] By rotating the threaded sleeve, the position of the threaded sleeve on the second retaining ring is adjusted. When the positioning ring abuts against the threaded sleeve, it cannot continue to move downward, thus controlling the hole depth. By adjusting the position of the threaded sleeve, the hole depth can be adjusted. At the same time, the threaded rod can guide the positioning ring.

[0011] Furthermore, a second retaining ring is fixedly connected to one end of the threaded rod that passes through the positioning ring, and a pressing spring is connected between the second retaining ring and the positioning ring, with the two ends of the pressing spring fixed to the second retaining ring and the positioning ring respectively.

[0012] Furthermore, three protrusions are fixedly provided on the positioning ring, and positioning screws are threaded onto the protrusions, with the axis of the positioning screws pointing towards the center of the positioning ring.

[0013] By rotating the connecting spring, one end of the positioning screw abuts against the electric drill, thereby limiting the electric drill's position. By adjusting the length of the protruding part of the positioning screw, the drill bit of the electric drill is controlled to be coaxial with the ring part.

[0014] Furthermore, a first retaining ring is fixedly connected to the marking pen, and a connecting spring is provided between the first retaining ring and the adjusting rod. The two ends of the connecting spring are respectively fixedly connected to the first retaining ring and the adjusting rod.

[0015] The first retaining ring ensures that the marking end of the pen is higher than the bottom of the ring. Pressing the pen compresses the connecting spring, causing the marking end of the pen to contact the surface of the part for marking.

[0016] Furthermore, an indicator window is provided on the sliding part, through which the ruler scale can be observed.

[0017] The beneficial effects of this application are as follows:

[0018] 1. By using the sliding part and the annular part, the sliding part is slid to the predetermined scale position of the ruler. The ruler is used to measure the drilled part, and the annular part is adjusted to the drilling position. At this time, the drilling position is marked by the annular groove, the sliding block and the marking pen. The marking range of the marking pen can be adjusted by the adjusting rod. The size of the hole drilled on the part can be marked for different sizes of drill bits, which is convenient for actual observation of the drilling range.

[0019] 2. With the positioning ring and threaded rod in place, the positioning ring limits the electric drill when drilling, and the threaded rod guides it to prevent the drilling from being skewed.

[0020] 3. Adjust the position of the threaded sleeve on the second retaining ring by rotating the threaded sleeve. When the positioning ring abuts against the threaded sleeve, it cannot move further downward, thus controlling the hole depth. Adjust the position of the threaded sleeve to adjust the hole depth.

[0035] Reference Figure 1-4A positioning ruler for assisting manual drilling includes: a ruler 10, a sliding part 11, a positioning screw 12, an annular part 13, an annular groove 15, a sliding block 16, an adjusting rod 17, a limiting screw 31, and a marking pen 18. Two rulers 10 are provided perpendicularly to each other. A sliding part 11 is provided on each ruler 10 and slides in cooperation with it. A limiting plate 26 is fixedly provided at one end of each ruler 10 for abutting against the side of the part to be drilled. Through the cooperation of the limiting plate 26 and the two rulers 10, points on the surface of the sheet metal part can be positioned. The sliding part 11 is sleeved on the ruler 10 and can slide and adjust its position on the ruler 10. The positioning screw 12 is threaded onto the sliding part 11. By rotating the positioning screw 12, one end of the positioning screw 12 can abut against the ruler 10, thereby positioning the sliding part 11. An indicator window 30 is provided on the sliding part 11, through which the scale of the ruler 10 can be observed. The annular part 13 is fixedly connected to the two sliding parts 11, so that the center of the annular part 13 is directly opposite the scale of the indicator window 30. An annular groove 15 is formed on the annular part 13 and is coaxially arranged with the annular part 13. The sliding block 16 is slidably disposed in the annular groove 15 and slides along the trajectory of the annular groove 15. The adjusting rod 17 passes through the sliding block 16 and is slidably engaged with the sliding block 16. The sliding direction of the adjusting rod 17 points to the axis of the annular part 13. A marking pen 18 is provided at one end of the adjusting rod 17. When marking, the sliding part 11 is slid to the predetermined scale position of the ruler 10. The ruler 10 is used to measure the drilled part, adjusting the annular part 13 to the drilling position with its center at the drilling point. The annular groove 15, sliding block 16, and marking pen 18 mark the drilling position. Simultaneously, the marking range of the marking pen 18 is adjusted by the adjusting rod 17, allowing for marking of the size of holes drilled on parts with different drill bit diameters, facilitating a more intuitive observation of the drilling range. To prevent the marking pen 18 from constantly contacting the part, a first retaining ring 20 is fixedly connected to the marking pen 18. A connecting spring 19 is provided between the first retaining ring 20 and the adjusting rod 17, with both ends of the connecting spring 19 fixedly connected to the first retaining ring 20 and the adjusting rod 17, respectively. When the marking pen 18 is pressed and the connecting spring 19 is compressed, the marking end of the marking pen 18 contacts the surface of the part. When not marking, the marking end of the marker 18 is higher than the bottom surface of the annular portion 13 and will not contact the surface of the part. The marker 18 can be any marker pen in the prior art. The adjustment rod 17 is provided with a scale, so that by observing the scale, the marker 18 can be positioned at the center of the annular portion 13, at which time the surface of the part at the center of the annular portion 13 can be marked.

[0036] A hinge portion 21 is fixedly provided on the annular portion 13, and a connecting ring 22 is hinged to the hinge portion 21. The connecting ring 22 has two states: a first state parallel to the upper end face of the annular portion 13 and a second state perpendicular to the upper end face of the annular portion 13, which are folded around the axis of the hinge portion 21. When marking, the connecting ring 22 can be adjusted to the second state to avoid obstructing the marking pen 18. After marking is completed, the marking pen 18 is moved to the position furthest from the central axis of the annular portion 13 by adjusting the lever 17. At this time, the connecting ring 22 is deflected from the second state to the first state, and the marking pen 18 and adjusting lever 17 will not obstruct the connecting ring 22. A positioning ring 14 is slidably provided on the connecting ring 22. When the connecting ring 22 is in the first state, the positioning ring 14 is coaxial with the annular portion 13.

[0037] Three threaded rods 23 are fixedly connected to the connecting ring 22. The threaded rods 23 pass through the positioning ring 14 and slide in engagement with the positioning ring 14. A second retaining ring 27 is fixedly connected to one end of the threaded rod 23 that passes through the positioning ring 14. A pressing spring 25 is connected between the second retaining ring 27 and the positioning ring 14. The two ends of the pressing spring 25 are fixed to the second retaining ring 27 and the positioning ring 14, respectively. When drilling, the positioning ring 14 limits the electric drill, making the drill bit coaxial with the annular part 13. At the same time, the threaded rods 23 guide the drill to prevent skewed drilling.

[0038] A threaded sleeve 24 is threadedly connected to the threaded rod 23, located between the connecting ring 22 and the positioning ring 14. The threaded rod 23 and two guide rods 26 are circumferentially distributed on the connecting ring 22. By rotating the threaded sleeve 24, its position on the second retaining ring 27 is adjusted. Thus, when the positioning ring 14 abuts against the threaded sleeve 24, it cannot move further downward, thereby controlling the hole depth. By adjusting the position of the threaded sleeve 24, the drilling depth can be adjusted.

[0039] The positioning ring 14 is fixedly provided with three circumferentially evenly distributed protrusions 28. The protrusions 28 are threaded with positioning screws 29. The axis of the positioning screws 29 points to the center of the positioning ring 14. By rotating the positioning screws 29, one end of the positioning screws 29 abuts against the electric drill, thereby limiting the electric drill. By adjusting the length of the positioning screws 29 extending out of the protrusions 28, the drill bit of the electric drill is controlled to be coaxial with the ring part 13, thus ensuring drilling accuracy.

[0040] Working process or usage method:

[0041] 1. During positioning, the annular part 13 is positioned at the drilling position by the ruler 10 and the sliding part 11, with the axis of the annular part 13 aligned with the drilling point. At this time, the sliding part 11 is positioned by the positioning screw 12, and the connecting ring 22 is adjusted to the second state. At this time, it will not obstruct the adjusting rod 17. The center position of the annular part 13 can be marked by the marking pen 18, and the sliding block 16 can slide along the trajectory of the annular groove 15. The drilling range can be marked according to the diameter of the drill bit.

[0042] 2. After marking is completed, move the adjusting rod 17 to the position furthest from the central axis of the annular part 13. At this time, the connecting ring 22 is deflected from the second state to the first state. At this time, the marking pen 18 and the adjusting rod 17 are located outside the connecting ring 22. The electric drill is limited by the three positioning screws 29. By rotating the threaded sleeve 24, the position of the threaded sleeve 24 on the second retaining ring 27 is adjusted. Thus, when the positioning ring 14 abuts against the threaded sleeve 24, it cannot continue to move downward, thereby controlling the hole depth. By adjusting the position of the threaded sleeve 24, the drilling depth is adjusted.
