Description

Technical Field

[0001] This utility model relates to the field of flanged pear-shaped clamps, specifically a flanged pear-shaped clamp that is easy to install. Background Technology

[0002] Flanging fixtures are devices used to fix the edges of workpieces. They are mainly used in machining or welding processes to ensure workpiece stability and improve machining efficiency.

[0003] For example, announcement number CN218168490U (named "Sheet Metal Flanging Fixture") includes a U-shaped frame. The bottom of the U-shaped frame has a driving assembly, and both sides of the U-shaped frame have clamping assemblies. Openings are located on both sides of the top of the U-shaped frame. The driving assembly includes a motor, which is fixedly installed on one side of the U-shaped frame. The motor's output end extends into the U-shaped frame and is fixedly connected to a worm gear. Rotating columns are rotatably connected to both sides of the bottom of the U-shaped frame via bearings. Turbines are fixedly connected to the outside of the two rotating columns. By setting up the driving assembly and clamping assembly, when clamping a sheet metal part, the sheet metal part is first placed at the top center of the U-shaped frame. The motor drives the worm gear to rotate forward and backward, which in turn drives the two worm gears to rotate forward and backward. The two rotating columns then rotate, causing the two lead screws to rotate forward and backward. The four lead screws move closer or further apart from the two lead screws, and the four rotating rods rotate until the two clamping plates move closer or further apart. This effectively fixes sheet metal parts of different sizes, improving work efficiency and practicality.

[0004] The aforementioned flanging clamp uses clamping components to hold and fix sheet metal parts. However, the clamping components have a limited range of fixing the sheet metal parts, and the clamping opening is not very secure, which makes it inconvenient to clamp sheet metal parts for flanging. To address this, we provide a convenient flanging pear-shaped clamp. Utility Model Content

[0005] The purpose of this utility model is to provide a conveniently installed flanging pear-shaped clamp to solve the problem mentioned in the background art that the existing flanging clamps use clamping components to clamp and fix sheet metal parts, but the clamping components have a limited fixing range for sheet metal parts and the clamping opening has poor firmness, resulting in inconvenience in flanging and clamping sheet metal parts.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conveniently installed flanged pear-shaped clamp, comprising a clamp platform, the clamp platform having two transverse guide grooves inside, each transverse guide groove having a threaded screw inside, a screw slider being movably mounted on the screw, and a movable base being welded to the upper end of the screw slider; Also includes: The clamp beam is located on the inner side of the movable platform, and a connecting shaft is welded to the rear end face of the clamp beam. An extension shaft is welded to one end of the connecting shaft. Both the connecting shaft and the extension shaft are rotatably connected to the movable platform in an anti-detachment through-connection manner. The lifting guide seat is welded to the upper end of the clamp beam, and a pear-shaped clamping plate is provided at the front end of the lifting guide seat. The pear-shaped clamping plate is welded to the clamp platform, and a movable clamping plate is provided above the pear-shaped clamping plate. A horizontal adjustment groove is provided at both ends of the clamp beam, and a screw hole plate is welded inside the horizontal adjustment groove. A horizontal screw is movably installed inside the screw hole plate, and a horizontal locking block is provided at one end of the horizontal screw.

[0007] Preferably, the top of the lifting guide seat is provided with a top screw hole, and a vertical screw is rotatably installed inside the top screw hole. The lifting guide seat is provided with a lifting slider that is movably lifted inside, and the lifting slider and the movable clamping plate are integrated into one structure.

[0008] Preferably, the lifting slider has a first pressing insertion hole inside, and the vertical screw is inserted into and abuts against the lifting slider through the first pressing insertion hole.

[0009] Preferably, the horizontal locking block has a second pressing insertion hole inside, through which the horizontal screw is inserted and abuts against the horizontal locking block.

[0010] Preferably, an outer ring block is provided on the outside of the extension shaft, the outer ring block is welded to the outer wall of the movable platform, and a socket ear plate is welded to one end of the extension shaft.

[0011] Preferably, the outer ring block has eight flange adjustment holes inside, and a positioning pin is inserted into one flange adjustment hole and the insertion ear plate.

[0012] Preferably, both ends of the clamping platform are fixed with servo motors by screws, and the output shaft of the servo motor is connected to the threaded screw inside the transverse guide groove through a coupling.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a servo motor to drive a lead screw to rotate, adjusting the distance between two movable platforms so that both ends of the sheet metal part abut against the two clamping beams. Then, four movable clamping plates are clamped and fixed to the upper ends of four pear-shaped clamping plates, and the four pear-shaped clamping plates are abutted and fixed by rotating a vertical screw, achieving vertical clamping and beam clamping of the sheet metal part. Finally, four horizontal clamping blocks are clamped to the four ends of the sheet metal part, and the horizontal clamping blocks are abutted and fixed by rotating a horizontal screw, thus clamping and fixing the sheet metal part from all directions. This prevents the sheet metal part from detaching from the clamp during the flanging process. It overcomes the problem that existing flanging clamps use clamping components to clamp and fix the sheet metal part, but the clamping components have a limited fixing range and poor clamping opening firmness, making sheet metal flanging clamping inconvenient.
