Description

Technical Field

[0001] This utility model relates to the field of power tool auxiliary devices, and in particular to an electric drill with an angle auxiliary positioning device. Background Technology

[0002] An electric drill is a common handheld power tool widely used in construction, decoration, and manufacturing to drill holes in materials such as metal, wood, and concrete. A traditional electric drill mainly consists of a motor, chuck, drill shank, and switch, and relies on the operator to manually control the feed direction and tilt angle of the drill bit.

[0003] However, manual hand-held operation makes it difficult to maintain a stable angle, especially in scenarios requiring angled drilling. Problems such as drill bit deviation and hole tilting are prone to occur, leading to hole position deviation, assembly difficulties, or even workpiece scrap.

[0004] Therefore, it is necessary to provide an electric drill with an angle-assisted positioning device to solve the above problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an electric drill with an angle-assisted positioning device.

[0006] This utility model provides an electric drill with an angle-assisted positioning device, comprising: Base plate; Two support blocks, both of which are fixedly connected to the surface of the base plate; An adjustable drilling mechanism is provided, comprising two sets of limiting components and an adjustable drilling assembly. The adjustable drilling assembly includes a rotating rod, a first support rod, a second support rod, a support plate, a lifting block, and an insertion hole. The two ends of the rotating rod are rotatably connected to the two support blocks, respectively. The first support rod is fixedly connected to the circumferential surface of the rotating rod, and the support plate is fixedly connected to the circumferential surface of the rotating rod. The lower end of the second support rod is fixedly connected to the surface of the support plate. The lifting block is slidably connected to the circumferential surfaces of the first and second support rods. The insertion hole is opened on the surface of the lifting block, and an electric drill is slidably connected to the inner wall of the insertion hole. Both sets of limiting components are used to restrict the rotation of the rotating rod.

[0007] Preferably, both sets of the limiting components include a handle and a limiting nut, the limiting nut being threadedly connected to the circumferential surface of the rotating rod, and the handle being fixedly connected to the surface of the limiting nut.

[0008] Preferably, a spring is fitted on the circumferential surface of the first support rod, with the upper end of the spring abutting the surface of the lifting block and the lower end of the spring abutting the surface of the rotating rod.

[0009] Preferably, the upper ends of both the first support rod and the second support rod are fixedly connected to a stabilizing block.

[0010] Preferably, an adjusting nut is threaded onto the circumferential surface of the second support rod.

[0011] Preferably, the two sets of limiting components are located symmetrically on both sides of the rotating rod.

[0012] Compared with related technologies, the electric drill with an angle-assisted positioning device provided by this utility model has the following beneficial effects: 1. By setting a rotatable adjustable drilling mechanism, and using a limit nut and handle to lock the angle of the rotating rod, the electric drill feeds in a preset direction. With the base plate as the reference surface and the support rod as the guide structure, the drilling angle is ensured to be accurate and stable. This replaces the traditional manual angle finding method and effectively solves the problem in the background technology of "drill bit deviation, hole tilting, hole position deviation and even workpiece scrap due to unstable operation", which significantly improves the hole forming accuracy and operation reliability.

[0013] 2. By setting an adjustable nut on the second support rod and cooperating with the lifting block to form a depth limiting structure, when the electric drill is pressed down, the lifting block slides to contact the adjusting nut and stops moving down, thus achieving precise control of the drilling depth; at the same time, the spring provides a reset buffer force to avoid hard impact on the parts and extend the service life. This design not only improves the consistency of multi-hole processing, but also reduces the time for repeated measurement and adjustment, further improving construction efficiency.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to the following: Figures 1 to 3 An electric drill with an angle-assisted positioning device includes: Base plate 1; Two support blocks 2 are fixedly connected to the surface of the base plate 1; The adjustable drilling mechanism includes two sets of limiting components and an adjustable drilling assembly. The adjustable drilling assembly includes a rotating rod 301, a first support rod 302, a second support rod 303, a support plate 304, a lifting block 305, and an insertion hole 306. The two ends of the rotating rod 301 are rotatably connected to the two support blocks 2 respectively. The first support rod 302 is fixedly connected to the circumferential surface of the rotating rod 301. The support plate 304 is fixedly connected to the circumferential surface of the rotating rod 301. The lower end of the second support rod 303 is fixedly connected to the surface of the support plate 304. The lifting block 305 is slidably connected to the circumferential surfaces of the first support rod 302 and the second support rod 303. The insertion hole 306 is opened on the surface of the lifting block 305. An electric drill is slidably connected to the inner wall of the insertion hole 306. Both sets of limiting components are used to limit the rotation of the rotating rod 301.

[0018] In the specific implementation process, the base plate 1 is placed on the surface of the plate to be drilled as a reference surface. The first support rod 302 and the second support rod 303 are grasped and rotated, which drives the rotating rod 301 to rotate within the support block 2, thereby adjusting the overall tilt angle of the support plate 304 and the lifting block 305. When the second support rod 303 forms the required drilling angle with the base plate 1, the rotation is stopped and the limit component is used for limiting. The electric drill is then inserted into the insertion hole 306 on the lifting block 5, allowing it to slide and feed in the set direction, thereby achieving precise control of the drilling angle. This replaces manual angle finding and effectively ensures the accuracy of the hole direction, improving the work accuracy.

[0019] refer to Figures 1 to 3 As shown, both sets of limiting components include a handle 401 and a limiting nut 402. The limiting nut 402 is threadedly connected to the circumferential surface of the rotating rod 301, and the handle 401 is fixedly connected to the surface of the limiting nut 402.

[0020] In the above embodiment, handles 401 and limiting nuts 402 are symmetrically arranged on both sides of the rotating rod 301. When the angle is adjusted to the correct position, the limiting nuts 402 are tightened by rotating the handles 401 and pressed against the side of the support block 2. The rotating rod 301 is fixed by using the self-locking principle of the thread, which prevents the angle from shifting due to vibration during drilling. This achieves quick locking and releasing, is easy to operate and has reliable positioning, and improves the stability and reusability of the device.

[0021] refer to Figures 1 to 3 As shown, a spring 7 is sleeved on the circumferential surface of the first support rod 302. The upper end of the spring 7 abuts against the surface of the lifting block 305, and the lower end of the spring 7 abuts against the surface of the rotating rod 301.

[0022] In the above embodiment, a spring 7 is sleeved on the first support rod 302, with its lower end abutting against the rotating rod 301 and its upper end abutting against the lifting block 305. When the hand-held electric drill applies downward force to drill a hole, the lifting block 305 slides down along the support rod and compresses the spring 7. After drilling is completed, the spring 7 automatically rebounds and pushes the lifting block 305 back to its original position, realizing reset buffering, avoiding damage to the components from impact, and providing moderate downward pressure assistance to reduce operator fatigue.

[0023] refer to Figures 1 to 3 As shown, the upper ends of the first support rod 302 and the second support rod 303 are both fixedly connected to a stabilizing block 6.

[0024] In the above embodiment, a stabilizing block 6 is added to the top of the first support rod 302 and the second support rod 303 to enhance the connection rigidity of the upper end of the support rod, prevent the electric drill from shaking during drilling and causing the lifting block 305 to wobble, improve the overall structural stability, make the electric drill slide more smoothly in the insertion hole 306, ensure that the drill bit feeds stably along the predetermined trajectory, and reduce hole position deviation.

[0025] refer to Figures 1 to 3 As shown, the circumferential surface of the second support rod 303 is threaded with an adjusting nut 5.

[0026] In the above embodiment, an adjusting nut 5 is threaded onto the second support rod 303. The position of the adjusting nut 5 on the rod is controlled by rotating the adjusting nut 5. When the electric drill is pressed down, the lifting block 305 slides down the rod until it contacts the adjusting nut 5 and stops, thereby limiting the maximum drilling depth and realizing depth limit control. This replaces repeated measurements, ensures that the depth of multiple holes is consistent, and improves the efficiency of batch operations and the quality of hole formation.

[0027] refer to Figures 1 to 3 As shown, the two sets of limiting components are symmetrically located on both sides of the rotating rod 301.

[0028] In the above embodiment, two sets of limiting components are symmetrically arranged on both sides of the rotating rod 301. When the limiting nuts 402 on both sides are tightened at the same time, the force on both ends of the rotating rod 301 is even, avoiding torsional deformation or eccentricity caused by unilateral tightening, ensuring accurate angle positioning and structural stability, and improving the balance and long-term reliability of the device.

[0029] The working principle of the electric drill with an angle-assisted positioning device provided by this utility model is as follows: When using this device, the base plate 1 is first pressed against the surface of the material to be processed as a reference surface. Then, by rotating the first support rod 302 and the second support rod 303, the rotating rod 301 is rotated. After adjusting to the required drilling angle, the limit nuts 402 on both sides are tightened to make them press against the support block 2, thereby fixing the rotation angle. Next, the electric drill is inserted into the insertion hole 306 of the lifting block 305. When the electric drill is pressed down, the lifting block 305 slides down along the support rod and compresses the spring 7. The drill bit feeds steadily in the set direction to complete the drilling. At the same time, the drilling depth can be controlled by adjusting the lower stroke of the lifting block 305 by adjusting the nut 5. The entire process is precisely guided by the mechanical structure to achieve the drilling angle and depth, replacing manual operation based on experience. This effectively solves the problems mentioned in the background technology, such as "it is difficult to maintain a stable angle by manual operation, which can easily cause drill bit deviation, hole tilting, hole position deviation, or even workpiece scrapping". It realizes fast, accurate, and repeatable directional drilling operations.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
