Description

Technical Field

[0001] The invention belongs to the field of clamps, and in particular relates to an obliquely opened clamp mechanism for automobile trim strips. Background Art

[0002] Trimmings are mainly used to decorate automobile bodies. With the development of the automobile industry, the demand for trims is increasing. During the processing of trims, they need to be clamped by claws. Most of the existing claws are direct clamping type, which use cylinders to drive the claws to clamp the two sides of the trim. Since the texture of the trim is relatively soft, the clamping force provided by the cylinder can easily cause the trim to deform. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an obliquely opened clamping claw mechanism for automobile trim strips in view of the current status of the prior art.

[0004] The technical solution adopted by the present invention to solve the above technical problems is: to provide an obliquely opened clamping jaw mechanism for automobile trim strips, comprising: a mounting seat, the end of which is provided with a workpiece placement groove;

[0005] A clamping claw seat, which is arranged on the mounting seat, and a movable space is opened in the clamping claw seat;

[0006] A clamping jaw cylinder connected to the clamping jaw seat, an output shaft is provided at the end of the clamping jaw cylinder, and the output shaft movably passes through the clamping jaw seat and extends into the movable space;

[0007] An engaging claw, one end of which is movably inserted into the movable space and is rotatably connected to the output shaft, and the other end of the engaging claw is provided with an engaging inclined surface;

[0008] When the output shaft moves backward, the engaging claw can be driven to rotate around the connection between the engaging claw and the output shaft, and the engaging inclined surface can move toward the workpiece placement groove.

[0009] In the above-mentioned oblique opening clamping jaw mechanism for automobile trim, the engaging claw includes an integrally formed engaging portion and a connecting portion, an angle is provided between the engaging portion and the connecting portion, the connecting portion is rotatably connected to the output shaft, and the engaging inclined surface is arranged at the end of the engaging portion.

[0010] In the above-mentioned oblique opening clamping jaw mechanism for automobile trim strips, the clamping jaw seat comprises: a mounting plate connected to the mounting seat;

[0011] A connecting plate, which is arranged on the mounting plate, the clamping cylinder is connected to the connecting plate, and the output shaft movably passes through the connecting plate;

[0012] A limiting member is arranged on the mounting plate, the movable space is enclosed by the limiting member and the connecting plate, and the embracing portion and the connecting portion both movably penetrate the limiting member.

[0013] In the above-mentioned oblique opening clamp mechanism for automobile trim, the limiting member includes a limiting horizontal plate and a limiting vertical plate, a telescopic gap is provided between the limiting horizontal plate and the limiting vertical plate, and the embracing portion is movably inserted into the telescopic gap.

DETAILED DESCRIPTION

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] like Figures 1 to 3As shown, the oblique opening clamping jaw mechanism for automobile trim strips comprises: a mounting seat 1, an end of which is provided with a workpiece placement groove 2; a clamping jaw seat, which is arranged on the mounting seat 1, and a movable space 3 is opened in the clamping jaw seat; a clamping jaw cylinder 4, which is connected to the clamping jaw seat, and an output shaft 5 is arranged at the end of the clamping jaw cylinder 4, and the output shaft 5 movably passes through the clamping jaw seat and extends into the movable space 3; an engaging jaw, one end of which is movably inserted into the movable space 3 and is rotatably connected to the output shaft 5, and the other end of the engaging jaw is provided with an engaging inclined surface 15; when the output shaft 5 moves backward, it can drive the engaging jaw to rotate around the connection between it and the output shaft 5 and the engaging inclined surface 15 can move toward the workpiece placement groove 2.

[0022] The clamping claw cylinder 4 is connected to the clamping claw seat, and the output shaft 5 extends into the movable space 3. One end of the engaging claw is movably inserted into the movable space 3. The output shaft 5 is rotatably connected to the end of the engaging claw. When the output shaft 5 moves backward, it can drive the engaging claw to rotate around the connection between it and the output shaft 5. Because the output shaft 5 moves backward, the engaging claw will also move backward at this time, that is, the other end of the engaging claw makes a circular motion while moving backward. The engaging claw is driven by the output shaft 5 from the expanded state to the contracted state, so that the engaging inclined surface 15 can move toward the workpiece placement groove 2 until the engaging inclined surface 15 abuts against the end face of the workpiece on the workpiece placement groove 2, ensuring that the engaging claw will not contact the two side ends of the workpiece.

[0023] The engaging claw includes an integrally formed engaging portion 6 and a connecting portion 7 , wherein an angle is formed between the engaging portion 6 and the connecting portion 7 , the connecting portion 7 is rotationally connected to the output shaft 5 , and an engaging inclined surface 15 is disposed at the end of the engaging portion 6 .

[0024] A folded angle is provided between the embracing portion 6 and the connecting portion 7 so that the opening of the embracing claws is larger, making it easier to place the workpiece in the workpiece placement groove 2 .

[0025] The clamping jaw seat includes: a mounting plate 8, which is connected to the mounting seat 1; a connecting plate 9, which is arranged on the mounting plate 8, the clamping jaw cylinder 4 is connected to the connecting plate 9, and the output shaft 5 movably passes through the connecting plate 9; a limiting member, which is arranged on the mounting plate 8, the movable space 3 is enclosed by the limiting member and the connecting plate 9, and the embracing part 6 and the connecting part 7 movably pass through the limiting member.

[0026] When the output shaft 5 moves forward and backward, the limiting member can limit the connecting portion 7 .

[0027] The limiting member comprises a limiting transverse plate 10 and a limiting vertical plate 11 . A telescopic gap 12 is defined between the limiting transverse plate 10 and the limiting vertical plate 11 . The embracing portion 6 is movably inserted into the telescopic gap 12 .

[0028] The connecting portion 7 is provided with a first inclined surface 13 and a second inclined surface 14 . The first inclined surface 13 is movably pressed against the position-limiting horizontal plate 10 , and the second inclined surface 14 is movably pressed against the position-limiting vertical plate 11 .

[0029] When the output shaft 5 moves backward, the second inclined surface 14 can slide on the limiting vertical plate 11, and then the limiting vertical plate 11 causes the connecting part 7 to rotate, that is, drives the engaging part 6 to contract. When the output shaft 5 moves forward, the second inclined surface 14 can slide along the limiting horizontal plate 10, so that the engaging part 6 expands.

[0030] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the scope defined by the spirit of the present invention.
