Description

Technical Field

[0001] This utility model relates to the technical field of positioning devices for drilling holes in automotive anti-collision beams, specifically a positioning device for drilling holes in automotive anti-collision beams. Background Technology

[0002] Drilling anti-collision beams is a crucial step in automobile manufacturing. Existing positioning devices for drilling anti-collision beams suffer from low positioning accuracy, leading to easy displacement of the anti-collision beams during drilling, which affects drilling quality and efficiency. Furthermore, adjusting the drilling position is inconvenient and cannot meet the drilling requirements of anti-collision beams of different specifications. Therefore, a positioning device for drilling anti-collision beams is proposed to solve the aforementioned problems. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a positioning device for drilling holes in automotive anti-collision beams, which has the advantages of accurate positioning and easy adjustment of the drilling position, thus solving the problems of low positioning accuracy and inconvenient drilling position adjustment in existing devices.

[0005] (II) Technical Solution

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a positioning device for drilling holes in an automobile anti-collision beam, including an anti-collision beam, clamping mechanisms are provided on both the left and right sides of the anti-collision beam, a pressing mechanism is provided on the top of each of the two clamping mechanisms, a sliding mechanism is provided on the opposite side of the two pressing mechanisms, and a drilling mechanism located between the two pressing mechanisms is slidably connected to the outside of the sliding mechanism.

[0007] The sliding mechanism includes two fixed plates, which are fixedly connected to opposite sides of two pressing mechanisms. Two sliding rods, symmetrically distributed front and back on the outside of the drilling mechanism, are slidably connected inside the two fixed plates. Two first fastening screws, which are threaded to the top of the two fixed plates and respectively contact the top of the two sliding rods, are also threaded to the top of the two fixed plates.

[0008] The drilling mechanism includes an assembly shell, on which sliding plates are fixedly connected to both the front and rear sides. The two sliding plates are slidably connected to the outer sides of the two sliding rods respectively. The top of each of the two sliding plates is threaded with a second fastening screw that contacts the top of the sliding rod on the same side.

[0009] The beneficial effects of this utility model are:

[0010] The clamping and pressing mechanisms securely clamp and press down the crash beam, ensuring it won't shift during drilling and improving drilling accuracy. The sliding mechanism works in conjunction with the drilling mechanism; by adjusting the position of the sliding rod within the fixed plate and the position of the sliding plate on the sliding rod, the position of the drilling mechanism can be flexibly adjusted to meet the drilling requirements of crash beams of different specifications.

[0011] The positioning device for drilling holes in the car anti-collision beam has the advantages of precise positioning and easy adjustment of the drilling position.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, the clamping mechanism includes a top plate located above the anti-collision beam. A screw is fixedly connected to the bottom of the top plate, and a base plate is sleeved on the outside of the screw. A reinforcing ring located outside the screw is fixedly connected to the top of the base plate, and a slot adapted to the anti-collision beam is opened on the top of the base plate. A nut located below the base plate is threadedly connected to the outside of the screw.

[0014] The beneficial effect of adopting the above-mentioned further solution is that by rotating the nut, the position of the base plate on the screw can be adjusted, thereby making the slot tightly engage with the anti-collision beam, achieving stable clamping of the anti-collision beam, which is suitable for anti-collision beams of different thicknesses.

[0015] Furthermore, a reinforcing rib is fixedly connected between the reinforcing ring and the base plate, and the nut is trapezoidal in shape and can be used as a base.

[0016] The beneficial effects of adopting the above-mentioned further solutions are that the reinforcing ribs can enhance the connection strength between the reinforcing ring and the base plate, and improve the stability of the clamping mechanism; the trapezoidal nut is used as a base, which can make the whole device more stable.

[0017] Furthermore, the pressing mechanism includes a column, which is fixedly connected to the top of the top plate. A pressure plate is slidably connected to the outside of the column. The bottom of the pressure plate and the top of the top plate are fixedly connected to the same spring located outside the column. A limit plate is fixedly connected to the top of the column, and a fixing plate is fixedly connected to the outside of the pressure plate.

[0018] The beneficial effects of adopting the above-mentioned further solution are that the spring can provide a certain rebound force, making it easier to lift the drilling mechanism after drilling is completed, while also playing a buffering role during drilling to avoid damage to the anti-collision beam; the limiting plate can prevent the pressure plate from falling off the column.

[0019] Furthermore, the sliding rod has limit grooves on both the front and rear sides, and four sliders are fixedly connected inside the fixing plate and are symmetrically distributed front and back. The four sliders are located inside the four limit grooves and are adapted to the four limit grooves respectively. The top of the sliding rod is flat and is adapted to the first fastening screw and the second fastening screw.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the cooperation between the slider and the limiting groove can limit the movement direction of the slide rod and ensure that the slide rod slides stably within the fixed plate; the flat surface at the top of the slide rod facilitates the tightening of the first fastening screw and the second fastening screw.

[0021] Furthermore, a drilling device is snapped into the interior of the assembly shell. The output end of the drilling device passes through the assembly shell and extends to the bottom of the assembly shell. A third fastening screw is threaded onto the outer side of the assembly shell and contacts the outer side of the drilling device. Anti-slip grooves are provided on the outer sides of the first and second fastening screws. The outer side of the third fastening screw is rounded. The first, second, and third fastening screws can all be rotated by hand.

[0022] The advantages of adopting the above-mentioned further solution are that the drilling equipment can be securely installed in the assembly housing by the third fastening screw, which is convenient for disassembly and replacement; the anti-slip grooves on the outside of the first and second fastening screws facilitate manual operation and improve adjustment efficiency; and the rounded corners on the outside of the third fastening screw can prevent scratches to the operator.
