Description

Technical Field

[0001] This utility model relates to the field of assembly tooling technology, specifically a multi-screw positioning and installation tooling. Background Technology

[0002] Currently, screws are mostly installed one by one. If multiple screws need to be tightened in the same plane and the torque of the screws needs to be precisely controlled, an electric screwdriver is often used to tighten the screws one by one. It is necessary to pre-tighten them first and then tighten them again by diagonal tightening.

[0003] When using the existing method of diagonal tightening for multi-screw positioning installation, the screws must first be screwed into the threaded holes for manual pre-tightening, then each screw must be pre-tightened in sequence using an electric screwdriver, and finally diagonally tightened. This process is cumbersome, inefficient, and does not make it easy to ensure that all screws are subjected to uniform force during installation and tightening, nor is it easy to install and tighten multiple screws simultaneously with the same force. Utility Model Content

[0004] The purpose of this invention is to provide a multi-screw positioning and installation fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-screw positioning and mounting fixture, comprising:

[0007] A fixed frame, with a rotating handle rotatably connected inside the fixed frame via a bearing;

[0008] The adjustment component is located below the fixed frame;

[0009] A transmission assembly is disposed above a fixed frame. The transmission assembly includes multiple threaded collars. A right-angle fixed ring is rotatably connected to the outer side of each threaded collar. Multiple telescopic transmission shafts are rotatably connected to the upper surface of the fixed frame via bearings at equal angles. A first bevel gear is fixedly installed on both the handle and the outer surface of the threaded collar.

[0010] An mounting assembly is disposed at the lower end of a threaded collar, the mounting assembly comprising multiple mounting rings.

[0011] Furthermore, the upper end of the threaded collar is screwed with a fixed threaded cap, and a screwdriver bit is movably inserted into the fixed threaded cap.

[0012] Furthermore, a sliding rod is symmetrically fixedly installed on the outer side of the mounting ring, and a sliding sleeve that is fixedly connected to the right-angle fixing ring is slidably connected to the outer side of the sliding rod. A spring is movably sleeved on the outer side of the sliding rod below the sliding sleeve.

[0013] Furthermore, multiple spring telescopic rods are symmetrically fixedly installed on the outer surface of the mounting ring, and baffles are symmetrically and movably provided below the mounting ring, with the multiple spring telescopic rods fixedly connected to the baffles at corresponding positions.

[0014] Furthermore, multiple telescopic rods are fixedly installed at equal angles inside the fixed frame. One end of each telescopic rod is fixedly connected to a right-angle fixed ring at the corresponding position. Both ends of the telescopic transmission shaft are fixedly installed with bevel gears. The bevel gears are meshed and connected to the bevel gears at the corresponding positions.

[0015] Furthermore, the adjustment component includes:

[0016] The rotating frame is rotatably connected to the lower end of the fixed frame via bearings.

[0017] Multiple arc-shaped slide rails are fixedly installed at equal angles on the outer surface of the rotating frame;

[0018] Multiple levers are rotatably connected inside the arc-shaped slide rail;

[0019] The first fixing ring is fixedly installed on the upper end of the lever and is rotatably connected to the telescopic end of the telescopic transmission shaft at the corresponding position.

[0020] Preferably, a fastening bolt is screwed onto the upper surface of the fixed frame, and the fastening bolt passes through the fixed frame and is movably fitted with the rotating frame.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. By inserting the screw into the mounting ring, two baffles support and initially fix it. The electric screwdriver drives the handle to rotate, causing the telescopic drive shaft to rotate the threaded collar, providing power for the rotation of the screwdriver bit inside. Pressing the fixing frame, the threaded collar drives the screwdriver bit to move down, pressing against the screw, so that the screwdriver bit and the screw nut are inserted. Then the electric screwdriver is continuously rotated to tighten multiple screws at the same time, so that multiple screwdriver bits rotate with the same force, which facilitates the simultaneous installation and tightening of multiple screws with the same force, improves the screw installation efficiency, and reduces the occurrence of uneven force when tightening multiple screws.

[0023] 2. Move the rotating frame to make multiple arc-shaped slide rails push the lever to move, which in turn moves the telescopic section of the telescopic transmission shaft to adjust the position of the threaded collar. This allows for simultaneous adjustment of multiple threaded collars. Then, tighten the fastening bolts so that their lower ends abut against the inner wall of the rotating frame to fix the rotating frame and improve the firmness and stability of the threaded collar position after adjustment.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-5 In this embodiment of the utility model, a multi-screw positioning and installation fixture includes a fixed frame 1. Inside the fixed frame 1, a rotating handle 101 is rotatably connected via bearings. An adjustment component 2 is located below the fixed frame 1, and a transmission component 3 is located above the fixed frame 1. The transmission component 3 includes multiple threaded collars 301. A right-angle fixed ring 306 is rotatably connected to the outer side of each threaded collar 301. Multiple telescopic transmission shafts 303 are rotatably connected to the upper surface of the fixed frame 1 via bearings at equal angles. The telescopic transmission shafts 303 can freely extend and retract to adjust the position of the installation component 4 and adapt to the installation of screws with different spacings. A first bevel gear 302 is fixedly installed on the outer surface of both the rotating handle 101 and the threaded collar 301. The installation component 4 is located at the lower end of the threaded collar 301 and includes multiple installation rings 402.

[0032] Specifically, a handle is provided on the fixed frame 1 for easy hand holding. The telescopic transmission shaft 303 is extended and retracted by adjusting component 2, and the position of mounting component 4 is adjusted. The bit inside the threaded collar 301 is rotated by transmission component 3, which tightens the screw inside the mounting ring 402.

[0033] Example 1

[0034] like Figure 1-4 As shown, in this embodiment, multiple telescopic rods 305 are fixedly installed at equal angles inside the fixed frame 1. One end of the telescopic rod 305 is fixedly connected to the right-angle fixed ring 306 at the corresponding position. Both ends of the telescopic transmission shaft 303 are fixedly installed with bevel gears 304. The bevel gears 302 and the bevel gears 304 at the corresponding positions are meshed and connected for transmission.

[0035] In this embodiment, the first telescopic rod 305 extends and retracts synchronously with the telescopic transmission shaft 303, maintaining the stability of the right-angle fixed ring 306. At the same time, the telescopic transmission shaft 303 passes through the right-angle fixed ring 306, improving the meshing stability of the first bevel gear 302 and the second bevel gear 304. The electric screwdriver drives the handle 101 to rotate. Through the transmission of the first bevel gear 302 and the second bevel gear 304, the telescopic transmission shaft 303 drives the threaded collar 301 to rotate, providing power for the rotation of the screwdriver bit inside.

[0036] like Figure 5 As shown, in this embodiment, a fixed threaded cap 401 is screwed onto the upper end of the threaded collar 301. A screwdriver bit is movably inserted into the fixed threaded cap 401. The screwdriver bit is installed inside the threaded collar 301 through the fixed threaded cap 401, which also makes it easy to replace the screwdriver bit. A sliding rod 404 is symmetrically fixedly installed on the outer side of the mounting ring 402. A sliding sleeve 403, which is fixedly connected to the right-angle fixed ring 306, is slidably connected to the outer side of the sliding rod 404. A spring 405 is movably sleeved on the outer side of the sliding rod 404 below the sliding sleeve 403.

[0037] In practice, the spring force of spring 405 pushes the slide bar 404 downward, making it easier to install the screw inside the mounting ring 402. When tightening the screw, multiple screws are first inserted into the threaded groove, and then the fixing frame 1 is pressed down. The threaded collar 301 drives the bit to move down and abut against the screw. Then the electric screwdriver drives the bit to rotate slightly, so that the bit is inserted into the screw nut. Then the electric screwdriver is continuously rotated to tighten multiple screws at the same time, so that multiple bits rotate with the same force, which makes it easier to install and tighten multiple screws at the same time with the same force, improving the screw installation efficiency and reducing the occurrence of uneven force when tightening multiple screws.

[0038] like Figure 4 and Figure 5As shown, in this embodiment, multiple spring telescopic rods 407 are symmetrically fixedly installed on the outer surface of the mounting ring 402. The spring telescopic rods 407 are provided with a return spring inside, so that the spring telescopic rods 407 always have a contraction force. Baffles 406 are symmetrically and movably provided below the mounting ring 402, and the multiple spring telescopic rods 407 are fixedly connected to the baffles 406 at the corresponding positions.

[0039] In practice, the screw is inserted into the mounting ring 402, and the two baffles 406 support and initially fix it. When tightening the screw to the end, the screw presses against the inclined surface in the middle of the baffle 406, causing the baffle 406 to move to both sides, so that the screw nut fits against the upper end of the thread groove, and the screw is completely tightened.

[0040] Example 2

[0041] Based on Embodiment 1, in order to solve the problem that multiple telescopic drive shafts 303 are not convenient to adjust simultaneously.

[0042] like Figure 2-4 As shown, in this embodiment, the adjustment component 2 includes: a rotating frame 201 rotatably connected to the lower end of the fixed frame 1 via a bearing; multiple arc-shaped slide rails 202 fixedly installed at equal angles on the outer surface of the rotating frame 201; multiple levers 203 rotatably connected to the inside of the arc-shaped slide rails 202; a first fixing ring 204 fixedly installed on the upper end of the lever 203 and rotatably connected to the telescopic end of the telescopic transmission shaft 303 at the corresponding position; and a fastening bolt 102 screwed onto the upper surface of the fixed frame 1, the fastening bolt 102 penetrating the fixed frame 1 and movably fitting against the rotating frame 201.

[0043] In practice, the rotating frame 201 is moved, causing multiple arc-shaped slide rails 202 to push the lever 203 to move. Under the sliding limit of the telescopic drive shaft 303 and the first telescopic rod 305, the lever 203 moves along the telescopic direction of the telescopic drive shaft 303, causing the telescopic section of the telescopic drive shaft 303 to move, adjusting the position of the threaded collar 301, so that multiple threaded collars 301 can be adjusted simultaneously. Then, the fastening bolt 102 is tightened so that its lower end abuts against the inner wall of the rotating frame 201, fixing the rotating frame 201 and improving the firmness and stability of the threaded collar 301 after position adjustment.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
