Description

Technical Field

[0001] This utility model relates to the field of automotive door frame processing technology, specifically to an automotive door frame clamping fixture. Background Technology

[0002] The car door frame refers to the frame surrounding the car door, usually made of metal or plastic. Its main function is to support the door, maintain its stability and airtightness, and also prevent door collisions and improve the overall structural strength of the vehicle. Car door frames are usually also equipped with sealing strips to prevent water and dust from entering the car and keep the interior clean and comfortable.

[0003] Chinese patent CN219562014U discloses a clamping fixture for an automotive door frame, relating to the technical field of automotive door frame processing equipment. It includes a clamping mechanism comprising a mounting frame, a first cylinder fixed at the center of the inner wall of the mounting frame, placement frames fixed at the ends of the horizontal output shafts of multiple sets of first cylinders, second anti-slip pads fixed at the bottom walls of the inner cavities of multiple placement frames, and mounting components extending into the inner cavities of multiple placement frames fixed at the top walls of the placement frames. A flipping mechanism includes a counterweight horizontal plate, a vertical plate fixed to one side of the top wall of the counterweight horizontal plate, and a first driving component fixed to the outer wall of the vertical plate. This application activates multiple sets of first cylinders to extend, causing the placement frames to move outward and engage with the automotive door frame. Then, the mounting components are activated to firmly clamp and fix the automotive door frame. Activating the first driving component causes the flipping frames to flip synchronously, thereby allowing the angle of the automotive door frame to be adjusted, facilitating welding processing on the other side of the automotive door frame.

[0004] The aforementioned patent addresses the drawback of existing clamping fixtures, which require welding only one side of the car door frame first, then removing the door frame, rotating it 180°, and re-fixing it before welding the other side, which is quite cumbersome. This implementation provides another solution to the problem raised in the aforementioned patent. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automotive door frame clamping fixture, which has the advantage of facilitating the flipping of the door frame. This solves the problem that existing clamping fixtures can only perform welding on one side of the door frame first, and after welding, the door frame must be removed, flipped 180°, and then re-fixed before welding the other side, which is quite cumbersome.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a car door frame clamping fixture, comprising a base platform and a turntable, wherein a rotating clamping mechanism is provided between the base platform and the turntable;

[0007] The rotating clamping mechanism includes a motor fixedly installed on the lower surface of the inner cavity of the base platform. A rotating rod extending through to the upper surface of the base platform is fixedly installed at the output end of the motor. A turntable is fixedly installed on the top of the rotating rod. A first U-shaped groove plate and a second U-shaped groove plate are fixedly installed on the upper surface of the turntable. Three miniature electric telescopic rods are fixedly installed on opposite sides of the inner surfaces of the first and second U-shaped groove plates. A clamping plate is fixedly installed at one end of each miniature electric telescopic rod. A rubber block is fixedly installed on the surface of the clamping plate. An mounting plate is fixedly installed on the opposite side of the first U-shaped groove plate. An electric telescopic rod is fixedly installed on the surface of the mounting plate. A clamping block is fixedly installed between two electric telescopic rods. A V-shaped groove is formed on the surface of the clamping block. Rubber strips are fixedly installed on opposite sides of the inner surfaces of the V-shaped groove.

[0008] Furthermore, the first U-shaped groove plate is vertically disposed on the surface of the turntable, and the second U-shaped groove plate is horizontally disposed on the surface of the turntable, with the first U-shaped groove plate and the second U-shaped groove plate being interconnected.

[0009] Furthermore, a fixing frame is fixedly installed on the surface of the motor. The fixing frame is ring-shaped and has multiple legs fixedly installed on its surface. The fixing frame is fixedly installed on the lower surface of the inner cavity of the base plate by the legs and bolts.

[0010] Furthermore, a sleeve is fixedly installed on the upper surface of the base platform, the opening size of the sleeve is the same as the inner diameter of the turntable, and an anti-detachment ring is fixedly installed on the side surface of the turntable, the diameter of the anti-detachment ring being larger than the opening diameter of the sleeve.

[0011] Furthermore, both the upper surface of the base platform and the lower surface of the turntable are provided with annular grooves, and a number of ball bearings are rolled and installed in the annular grooves.

[0012] Furthermore, a circular hole communicating with the inner cavity of the base platform is provided on the upper surface of the base platform, and the rotating rod is located in the circular hole.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This automotive door frame clamping fixture features a rotating clamping mechanism between a base and a turntable. During use, the door frame is clamped and fixed onto the turntable, and then the turntable is driven by a motor to rotate, facilitating the processing of both sides of the door frame. This solves the problem of existing clamping fixtures requiring welding only one side of the door frame first, followed by removal, 180° rotation, and re-fixing before welding the other side – a cumbersome process.
