Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to a clamping fixture for sheet metal processing. Background Technology

[0002] In automated equipment, centering and clamping fixtures are required to center and clamp the raw materials, making it easier for the robot to pick them up. The robot's movement is point-to-point. If there is a problem with the placement of the material at the origin (such as tilting), the same problem will occur at the destination, which will affect subsequent processing steps.

[0003] Therefore, a centering clamping fixture is needed to center and fix the material, making it easier for the robot to pick up the material.

[0004] Chinese Patent Application No. 202322277615.6 discloses a sheet metal processing clamping device, including a base and two first L-shaped clamping plates. Support rods are fixedly connected to the outer surfaces of the front and rear sides of each of the first L-shaped clamping plates. Movable rods are movably fitted onto the outer surfaces of the two support rods. Second L-shaped clamping plates are fixedly connected to the outer surfaces of the two movable rods away from the support rods. Threaded holes are formed on the outer surfaces of both the support rods and the movable rods, and bolts are threaded into the corresponding threaded holes on the support rods and movable rods. This sheet metal processing clamping device, by setting up support rods and movable rods, and cooperating with threaded holes and bolts, solves the problem that in most existing clamping devices, the clamping plate area is fixed and cannot be adjusted. When clamping a large area of ​​sheet metal, the clamping force is concentrated in one place, resulting in unstable clamping of the sheet metal.

[0005] It uses positive and negative lead screws to drive the connecting block to move, thereby clamping and fixing the sheet metal parts. However, the positive and negative lead screws have high requirements for the operating environment and are expensive.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of this utility model is to provide a clamping fixture for sheet metal processing that can effectively solve the above-mentioned technical problems.

[0008] To achieve the purpose of this utility model, the following technical solution is adopted:

[0009] A clamping fixture for sheet metal processing includes: a fixed plate; a cylinder fixedly mounted on the fixed plate, the cylinder extending in an inclined direction relative to the fixed plate; a fixed seat fixedly mounted on the fixed plate, a rotating hole provided on one side of the fixed seat, a rotating shaft rotatably connected to the rotating hole; a rotating body fixedly connected to the end of the rotating shaft, the end of the piston rod of the cylinder being rotatably connected to the rotating body; two hinged rods movably connected to the rotating body, the ends of the hinged rods being hinged to pressing blocks.

[0010] Furthermore, the cylinder is tilted and mounted on the fixed plate.

[0011] Furthermore: the rotating shaft is fixedly connected to the middle of the rotating body, one end of the hinge rod is movably connected to the edge of the rotating body, and the other end of the hinge rod is movably connected to the end of the pressing block.

[0012] Furthermore, the middle part of the pressing block is rotatably connected to the edge of the fixed base.

[0013] Furthermore: an elastic body is fixedly installed on the fixed base, and a movable plate is fixedly connected to the elastic body. When the rotating body rotates, it contacts the surface of the movable plate.

[0014] Furthermore: a guide rod is fixedly connected to the movable plate, the guide rod passes through the fixed base, and a guide component is fixedly connected to the guide rod.

[0024] like Figures 1 to 3 As shown, the clamping fixture for sheet metal processing of this utility model includes: a fixed plate 1; a cylinder 2 fixedly installed on the fixed plate 1, the tail of the cylinder 2 being fixedly connected to the fixed plate 1 via a mounting seat 3, the cylinder 2 being inclinedly arranged on the fixed plate 1, and when the piston rod of the cylinder 2 extends, it extends along the axial direction of the cylinder 2, that is, the extension direction of the cylinder 2 is inclined to the fixed plate 1; a fixed seat 4 fixedly installed on the fixed plate 1, the fixed seat 4 being fixedly installed by bolts, a rotating hole 5 being provided on one side of the fixed seat 4, and a rotating shaft 6 being rotatably connected to the rotating hole 5; a rotating body 7 being fixedly connected to the end of the rotating shaft 6, and the end of the piston rod being rotatably connected to the rotating body 7; two hinged rods 8 being movably connected to the rotating body 7, and a pressing block 9 being hinged to the end of the hinged rod 8; when the cylinder 2 drives the rotating body 7 to rotate, it pulls the hinged rods 8, causing the pressing block 9 to contact the sheet metal part and fix the sheet metal part.

[0025] It should be explained in detail here that the rotating shaft 6 is fixedly connected to the middle of the rotating body 7, one end of the hinge rod 8 is movably connected to the edge of the rotating body 7, the other end of the hinge rod 8 is movably connected to the end of the pressing block 9, and the middle of the pressing block 9 is rotatably connected to the edge of the fixed seat 4. Thus, when the cylinder 2 drives the rotating body 7 to rotate, the middle of the rotating body 7 will rotate around the rotating shaft 6, which will drive the hinge rod 8 to rotate, thereby causing the pressing block 9 to rotate around its middle, and thus perform pressing.

[0026] As a further improvement of this application: an elastic body 11 is fixedly installed on the fixed base 4, and a movable plate 10 is fixedly connected to the elastic body 11. When the rotating body 7 rotates, it contacts the surface of the movable plate 10. When the rotating body 7 rotates, it pushes the movable plate 10 to move upward. When the rotating body 7 does not push the movable plate 10, the movable plate 10 moves downward under the action of gravity. A guide rod 12 is fixedly connected to the movable plate 10. The guide rod 12 passes through the fixed base 4. A guide member 13 is fixedly connected to the guide rod 12. The guide member 13 is generally conical.

[0027] In actual use, when the moving plate 10 moves upward, the guide rod 12 drives the guide member 13 to move upward. The guide member 13 passes through the through hole on the sheet metal part. Since the guide member 13 is cone-shaped, when the sheet metal part is not properly positioned, the guide member 13 will pass through the through hole on the sheet metal part to align the sheet metal part.

[0028] It should be added here that the fixed base 4 is provided with a through hole, and the guide rod 12 passes through the through hole and slides in contact with its inner wall, so that the guide rod 12 can guide the movement of the moving plate 10, so that the moving plate 10 can move vertically up and down.

[0029] The material of the elastic body 11 can be rubber or an elastic telescopic rod.

[0030] Working principle:

[0031] When the cylinder 2 drives the rotating body 7 to rotate, the middle part of the rotating body 7 will rotate around the rotating shaft 6, driving the hinge rod 8 to rotate, thereby causing the pressing block 9 to rotate around its middle part. Moreover, during this process, the rotating body 7 will push the moving plate 10 to move upward. Under the action of the guide rod 12, the moving plate 10 will move vertically upward, so that the conical guide 13 can pass through the through hole on the sheet metal part. On the one hand, the guide 13 will align the sheet metal part, and on the other hand, the pressing block 9 will press the sheet metal part.

[0032] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
