Description

Technical Field

[0001] This utility model relates to an auxiliary positioning mechanism for an impact drill, belonging to the field of drilling tool technology. Background Technology

[0002] In various building construction and equipment installation scenarios, after the fixture is installed and leveled, it needs to be fixed to the ground with expansion bolts. Currently, the ground mounting holes for the bolts are usually drilled manually using a hand-held impact drill.

[0003] Impact drills achieve drilling through a combination of impact and rotation. Because of the significant impact force generated during drilling, they are difficult to control. In actual drilling operations, a high level of operator skill is required. If the operator lacks proficiency, it is difficult to accurately control the drilling position and direction when using a handheld impact drill. This often leads to a series of adverse consequences, such as drilling holes that are too large, exceeding actual needs and affecting the stability of subsequent expansion bolt installation; off-center holes, where the actual hole position deviates from the intended position, preventing the fixture from accurately fixing the hole as designed; and skewed holes are also common, where the hole's axis deviates from the intended direction, similarly negatively impacting installation quality and structural stability.

[0004] These problems not only affect the quality of drilling, increase the rework rate during construction, and raise construction costs, but also increase the difficulty of drilling operations, requiring operators to expend more physical strength and energy to complete the drilling work, resulting in greater labor intensity. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary positioning mechanism for impact drills, so as to effectively improve drilling quality, reduce drilling difficulty, and reduce the labor intensity of operators.

[0006] The technical solution provided by this utility model is as follows: An auxiliary positioning mechanism for an impact drill includes a first support arm, a second support arm, a mounting bracket, a gear, a rack, a gas spring, and a connector. The connector is rotatably connected to the end of the first support arm in a manner that allows it to rotate around the Z-axis. The connector is also pinned to the second support arm via a pin. The two ends of the gas spring are respectively connected to the connector and the second support arm. The mounting bracket is connected to the end of the second support arm away from the connector. The gear is rotatably disposed within the mounting bracket. The rack is mounted on the mounting bracket in a manner that allows it to rise and fall along the Z-axis, and the rack meshes with the gear. The lower end of the rack is provided with a fixing sleeve for fixing the impact drill.

[0007] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: The impact drill auxiliary positioning mechanism provided by this utility model can achieve stable support and precise positioning of the impact drill. The connecting piece can rotate around the Z-axis, and is connected to the second support arm via a pin and rotates around the pin, allowing the impact drill to perform drilling operations at different angles and positions. The gas spring provides the necessary buffering and support force, and the cooperation of the gear and rack enables the rack to rise and fall along the Z-axis to adapt to drilling requirements of different depths. The fixed sleeve ensures the stability of the impact drill during operation, avoiding drilling position deviations caused by impact drill shaking.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the gear is connected to a handle, and by operating the handle, the gear is driven to rotate, causing the rack to move up and down along the Z-axis.

[0010] The beneficial effect of adopting the above-mentioned further solution is that, during the drilling process, the operator can conveniently adjust the height of the rack through the handle, thereby adjusting the drilling depth of the impact drill, replacing the handheld impact drill, and making drilling more stable.

[0011] Furthermore, it also includes a mobile trolley and a rotating seat, the rotating seat being disposed on the mobile trolley, and the end of the first support arm away from the connector being rotatably connected to the mobile trolley via the rotating seat.

[0012] The beneficial effect of adopting the above-mentioned further solution is that, by adding a mobile trolley and a rotating seat, the operator can easily move the auxiliary positioning mechanism to different working positions and adjust the angle of the first support arm by rotating the seat to adapt to different working requirements.

[0013] Furthermore, the connector is rotatably connected to the end of the first support arm via a bearing unit.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the use of bearing unit connection makes the rotation of the connecting parts more stable and smooth, and reduces friction and resistance.

[0015] Furthermore, a support block is provided on the first support arm.

[0016] The advantage of adopting the above-mentioned further solution is that, when not in use, the first support arm can be rotated above the second support arm for folding and storage. At this time, the support block is located between the first and second support arms, preventing them from colliding with each other and avoiding damage, while also reducing space occupation and facilitating carrying and storage.

[0017] Furthermore, the second support arm includes a first link and a second link, the first link and the second link are arranged in parallel, and the two ends of the first link and the second link are respectively pin-connected to the mounting bracket and the connector.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the second support arm adopts a double linkage structure, which can withstand greater impact force and torque, and improves the load-bearing capacity and stability of the entire auxiliary positioning mechanism.

[0019] Furthermore, the mobile trolley includes a base, casters, a push handle, and a foot brake. The base has a fixing position for fixing the rotating seat, the push handle is located on one side of the base, the casters are located at the bottom of the base, and the foot brake is used to lock the casters to prevent the mobile trolley from moving.

[0020] The advantages of adopting the above-mentioned further solution are that the fixing holes on the base are used to fix the rotating seat, the push handle makes it convenient for the operator to push the trolley to move, and the combined use of the casters and foot brakes allows the trolley to move flexibly and be stably fixed in a designated position when needed.

[0021] Furthermore, the rack is provided with a connecting block, the connecting block is provided with a locking block, and the fixing sleeve is detachably connected to the connecting block.

[0022] The beneficial effect of adopting the above-mentioned further solution is that, through the setting of connecting blocks and locking blocks, the impact drill can be easily installed and disassembled, avoiding the drilling position deviation caused by the impact drill becoming loose.

[0035] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0036] like Figure 1 - Figure 5As shown, an auxiliary positioning mechanism for an impact drill includes a moving trolley 7, a rotating base 8, a first support arm 1, a second support arm 2, a mounting bracket 3, a gear 301, a rack 302, a gas spring 4, and a connecting member 5. The rotating base 8 is mounted on the moving trolley 7. One end of the first support arm 1 is rotatably connected to the moving trolley 7 via the rotating base 8, and the first support arm 1 is rotatable about the Z-axis. The connecting member 5 is rotatably connected to the other end of the first support arm 1 in a manner that allows it to rotate about the Z-axis. The connecting member 5 is also pinned to the second support arm 2 via a pin, thereby allowing the second support arm 2 to rotate about the Z-axis. The pin rotates, and the connecting member can be two opposing connecting plates. The two ends of the gas spring 4 are respectively connected to the connecting member 5 and the second support arm 2. The gas spring 4 provides necessary buffering and support force for the second support arm 2. The mounting bracket 3 is pinned to the end of the second support arm 2 away from the connecting member 5. The gear 301 is rotatably disposed in the mounting bracket 3. The rack 302 is mounted on the mounting bracket 3 in a manner that allows it to rise and fall along the Z-axis, and the rack 302 meshes with the gear 301. The lower end of the rack 302 is provided with a fixing sleeve 13 for fixing the impact drill 14.

[0037] The gear 301 is connected to a handle 6. By operating the handle 6, the gear 301 is driven to rotate, causing the rack 302 to move up and down along the Z-axis.

[0038] The connector 5 is rotatably connected to the end of the first support arm 1 via the bearing unit 9.

[0039] The first support arm 1 is provided with a support block 10, for reference Figure 8 As shown, when not in use, the first support arm 1 can be rotated above the second support arm 2 for folding and storage. At this time, the support block 10 is located between the first support arm 1 and the second support arm 2, preventing them from colliding with each other and avoiding damage, while also reducing space occupation and making it easy to carry and store.

[0040] The second support arm 2 includes a first link 101 and a second link 102. The first link 101 and the second link 102 are arranged in parallel. The two ends of the first link 101 and the second link 102 are respectively pin-connected to the mounting bracket 3 and the connector 5. The first link 101, the second link 102, the mounting bracket 3 and the connector 5 form a four-bar linkage mechanism.

[0041] The mobile trolley 7 includes a base 701, casters 702, a push handle 703, and a foot brake 704. The base 701 has a fixing hole on its upper part for fixing the rotating seat 8. The push handle 703 is located on one side of the base 701, making it easy for the operator to push the trolley to move. The casters 702 are located at the bottom of the base 701, allowing the trolley to move flexibly between different working positions. The foot brake 704 is used to lock the casters 702. When it is necessary to fix the position of the trolley, the operator can use the foot brake 704 to stably fix the trolley in the designated position and prevent the trolley from moving during operation.

[0042] The rack 302 is provided with a connecting block 11, the connecting block 11 is provided with a locking block 12, and the fixing sleeve 13 is detachably connected to the connecting block 11. In use, the impact drill 14 is fixed to the rack 302 by the locking block 12 and the fixing sleeve 13, and the impact drill 14 can move with the movement of the rack 302.

[0043] The impact drill 14 can move horizontally through the cooperation of the rotating seat 8 and the bearing unit 9, and can move vertically through the four-bar linkage.

[0044] The method for drilling using the auxiliary positioning mechanism of the impact drill 14 is as follows:

[0045] S1. Place the impact drill 14 into the fixing sleeve 13 at the lower end of the rack 302, with the drill bit of the impact drill 14 pointing vertically downward. Use the locking block 12 to fasten the impact drill 14. By rotating the bolt on the locking block 12 or using other locking methods, make the locking block 12 fit tightly against the impact drill 14 and firmly fix it in the fixing sleeve 13 to prevent the impact drill 14 from shaking or falling off during the drilling process.

[0046] S2. Push the mobile carriage 7 equipped with the impact drill 14 to the vicinity of the predetermined hole position. When the carriage reaches the appropriate position, step on the foot brake 704 equipped with the mobile carriage 7 to firmly fix the carriage on the ground and prevent the carriage from moving during the drilling process.

[0047] S3, Reference Figure 6 and Figure 7 The operator holds handle 6 and moves impact drill 14 to the desired drilling position, and impact drill 14 is accurately positioned.

[0048] S4. Turn on the switch of the impact drill 14 to start it working. Simultaneously, continue to slowly rotate the handle 6 connected to the gear 301. Through the meshing transmission of the gear 301 and rack 302, the impact drill 14 descends at a stable speed. During its descent, the impact drill 14 drills a hole in the ground. As the impact drill 14 continues to descend, the hole depth gradually increases. During drilling, it is important to maintain a uniform rotation speed of the handle 6 to avoid problems such as uneven hole diameter or rough hole walls caused by excessively fast or slow speeds.

[0049] S5. Continuously observe the hole depth according to the actual drilling requirements. The hole depth can be accurately determined by setting a depth mark on the rack 302 or by installing a depth measuring device on the impact drill 14. When the hole depth reaches the required size, stop rotating the handle 6 connected to the gear 301 to stop the impact drill 14 from descending. Then turn off the switch of the impact drill 14 to stop its operation.

[0050] S6. If multiple holes need to be drilled, repeat steps S2-S5 to complete the drilling of multiple holes.

[0051] S7. After completing all drilling tasks, first remove the impact drill 14 from the fixed sleeve 13, then release the foot brake 704 of the moving trolley 7, and move the trolley to the designated storage position, such as... Figure 8 As shown, the first support arm 1 is rotated to be above the second support arm 2 for folding and storage.

[0052] The impact drill 14 auxiliary positioning mechanism provided by this utility model can replace manual hand-held impact drill 14 for drilling, and achieve stable support and precise positioning of impact drill 14.
