Description

Clipper with quick clamping function

The present invention relates to the technical field of a spreader, in particular a clip hanger for connecting to a transport device and moving with the transport device.

Generally, for the surface processing of a light weight and small workpiece, such as painting the surface of the workpiece or other similar processing procedures, a suitable gripper can be used to clamp and move the workpiece.

Taiwan Patent No. M402879 discloses a hanger device which is provided with a hanging clamp on a hanger base, the hanger has opposite first and second clamping portions, and the first and second clamping portions respectively The clamping arm and the actuating arm have a shaft connecting portion between the clamping arm and the trigger arm, and the first and second clamping portions are rotatably shaft-mounted on the hanger seat by the shaft connecting portion. When the hanger passes a touch device, the contact arm of the hanger is touched to open the clamp arm; after the hanger passes the device, the clamp arm of the hanger returns to the clamping position.

It should be noted that the touch device is a front end plate and a rear slant plate formed at an opposite end of a pressing plate. The hanging clip moves from the front slanting plate into the pressing plate, the hanging is gradually opened; the hanging clip moves within the length of the pressing plate, and the hanging clip is continuously opened; the hanging clip is moved by the pressing plate The rear sloping plate is hanged and gradually clamped. In other words, within the total length of the compression plate and the rear swash plate, the workpiece cannot be removed because the hanger has not been clamped, otherwise the workpiece will fall. Therefore, it is obviously time consuming and inconvenient for the processing program.

The purpose of the present invention is to provide a clip hanger with a quick grip function, which has the effect of enabling the clip hanger to be quickly opened and closed for gripping a workpiece and improving production efficiency.

The object of the present invention is to provide a clip hanger with a quick grip function, which has the effect of being able to adjust the opening and closing angle (opening and closing range).

In order to achieve the above purpose and effect, the clip hanger is mounted on one side of a substrate, and the first clamp group can be opened and closed for holding a workpiece. Further, the first clamping group includes a first clamping arm and a second clamping arm, the first clamping arm is opposite to the second clamping arm and is respectively pivoted on the substrate, and one side of the first clamping arm Extending outwardly, a first pushing portion protrudes, and one side of the second clamping arm extends outwardly with a protruding second pushing portion. The first pushing portion and the second pushing portion can push the first clamping arm and the second clamping arm to be relatively open by a suitable pushing device, such as a pneumatic cylinder. And the pushing stroke of the pushing device can be used to adjust the opening angle of the first clamping arm and the second clamping arm.

The following is a detailed description of the preferred embodiments and the drawings in accordance with the purpose and function of the present invention.

Referring to FIGS. 1 and 2, a clip hanger includes a substrate 10 and a first clamping group 20. The first clamping group 20 is mounted on one side of the substrate 10, and the first clamping group 20 is openable for clamping a workpiece (not shown).

Further, the first clamping group 20 is pivotally disposed on the substrate 10. A spring 28 is a first clamping arm 22 and a second clamping arm 24. The first clamping arm 22 is opposite to the second clamping arm 24 and is disposed between the first clamping arm 22 and the second clamping arm 24 with a pivoting shaft 26, and the two ends of the spring 28 are respectively The first clamp arm 22 and the second clamp arm 24 are connected.

It should be noted that one side of the first clamping arm 22 extends outwardly with a first pushing portion 30 protruding. One side of the second clamping arm 24 extends outwardly with a second pushing portion 32 protruding.

A further first positioning shaft 34 is mounted at one end of the first clamp arm 22. A second positioning shaft 36 is mounted at one end of the second clamp arm 24. A first auxiliary lever 38 is disposed on the substrate 10 and opposite to one end of the first clamping group 20. The first auxiliary lever 38 can be used to stop the first positioning shaft 34 located at one end of the first clamping arm 22 and the second positioning shaft 36 located at one end of the second clamping arm 24.

Referring to FIG. 3, the first pushing portion 30 and the second clamping portion are pushed by a suitable pushing device (for example, a pneumatic cylinder, not shown), thereby pushing the first clamping arm 22 and the second clamping arm. 24 is rotated by the pivot shaft 26 as a rotation axis, such that the first clamp arm 22 and the second clamp arm 24 can be relatively open.

When the force acting on the first pushing portion 30 and the second pushing portion 32 is released, the first clamping arm 22 and the second clamping arm 24 can be restored to the initial state by the spring 28 Location (as shown in Figure 1). Further, the first positioning shaft 34 and the second positioning shaft 36 are reliably disposed on the first auxiliary lever 38 or the substrate 10.

According to the structure of the present invention and the manner of actuation thereof, the operator can move a predetermined workpiece (not shown) to the first clamp arm 22 and the first clamp arm 22 and the second clamp arm 24 are opened. The second clamping arm 24 then releases the force acting on the first pushing portion 30 and the second pushing portion 32 to form the first clamping arm 22 and the second clamping arm 24 to clamp Workpiece.

Thus, the first clamping arm 22 and the second clamping arm 24 are opened, and the workpiece is moved into the first clamping arm 22 and the second clamping arm 24 to clamp the workpiece. The first clamping arm 22 and the second clamping arm 24 can be used in the whole process. Quick opening and closing and short time consumption can increase production efficiency.

Then, the pushing device pushes the strokes of the first pushing portion 30 and the second pushing portion 32 to correspond to the opening and closing angle of the first clamping arm 22 and the second clamping arm 24. In other words, the effect of adjusting the opening and closing angle of the first clamping arm 22 and the second clamping arm 24 can be achieved by changing the actuation stroke of the pushing device.

Referring to Figures 4 and 5, another embodiment of the present invention includes a second clamping set 40. The second clamping group 40 is mounted on the other side of the substrate 10 and parallel to the first clamping group 20. Further, the second clamping group 40 includes a third clamping arm 42 and a fourth clamping arm 44. The third clamping arm 42 is opposite to the fourth clamping arm 44 and is pivoted on the substrate 10 , and a spring 46 is connected to the third clamping arm 42 and the fourth clamping arm 44 . Further, one side of the third clamping arm 42 extends outwardly with a protruding third pushing portion 48. One side of the fourth clamping arm 44 extends outwardly with a protruding fourth pushing portion 50.

A third positioning shaft 52 is mounted on one end of the third clamping arm 42. A fourth positioning shaft 54 is mounted on one end of the fourth clamping arm 44. A second auxiliary blocking lever 56 is disposed on the substrate 10 and opposite thereto. One end of the second clamping group 40, and the second auxiliary blocking lever 56 is used for stopping the third clamping arm The third positioning shaft 52 at one end of 42 and the fourth positioning shaft 54 at one end of the fourth clamping arm 44.

In the same manner as the operation of the previous embodiment, the third clamping arm 42 and the fourth clamping arm 44 can be opened in a relatively open manner by pushing the third pushing portion 48 and the fourth pushing portion 50 by a suitable pushing device. . When the force of the pushing device is released, the third clamping arm 42 and the fourth clamping arm 44 can return to the initial position under the action of the spring 46.

The above is a preferred embodiment and a design of the present invention. The preferred embodiments and the drawings are merely illustrative and not intended to limit the scope of the present invention. The scope of the rights covered by the contents of the “Scope of Application for Patent Application” shall not fall within the scope of this new type and shall be the scope of rights of the applicant.
