On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0025] See also Figures 1 to 4 , is an automatic workpiece clamping and flipping device according to an embodiment of the present invention, comprising a flipping assembly 10 and a clamping jaw assembly 20 installed on one side of the flipping assembly 10 .

[0026] The flip assembly 10 includes a fixed seat 11, a motor 12 mounted on the bottom surface of the fixed seat 11, a rotating member 13 rotatably mounted on the side of the fixed seat 11, a plurality of guide rods 14 evenly spaced and connected to a side of the rotating member 13 facing away from the fixed seat 11, and a push-pull cylinder 15 connected to one end of the guide rod 14 away from the rotating member 13. The fixed seat 11 is hollow, the rotor of the motor 12 is inserted into the interior of the fixed seat 11 and is coaxially connected to a first bevel gear 120, one end of the rotating member 13 is inserted into the interior of the fixed seat 11 and is coaxially connected to a second bevel gear 130, the second bevel gear 130 is matched and meshed with the first bevel gear 120, so that the motor 12 can drive the rotating member 13 to perform compound rotation to achieve flipping of the workpiece.

[0027] In this embodiment, the maximum rotation angle of the rotating member 13 is 180 degrees.

[0028] In this embodiment, the axis direction of the motor 12 and the axis direction of the rotating member 13 are perpendicular to each other.

[0029] The clamping jaw assembly 20 includes a movable support 21 slidably connected to the guide rod 14, force arms 22 hingedly installed on opposite sides of the top of the movable support 21, clamping blocks 23 respectively installed at the ends of each force arm 22, distance sensors 24 respectively installed on one side of each clamping block 23, a driving rod 25 hingedly connected to the middle of each force arm 22, and a clamping cylinder 26 installed at the bottom of the movable support 21; one side of the movable support 21 is used to connect the piston rod of the push-pull cylinder 15; the piston rod of the clamping cylinder 26 passes through the movable support 21 and then hingedly connects the two driving rods 25 upward and away from the end of the force arm 22, so that the clamping cylinder 26 can drive the two force arms 22 to approach each other, that is, the two clamping blocks 23 to approach each other, so as to clamp the workpiece.

[0030] In actual use, the automatic workpiece clamping and flipping device of the utility model is placed between two workstations, and the motor 12 is used to drive the entire clamping jaw assembly 20 to move to one workstation. After the two force arms 22 are controlled by the clamping cylinder 26 to clamp the workpiece, the motor 12 rotates in the opposite direction to drive the entire clamping jaw assembly 20 to move to another workstation. The clamping cylinder 26 controls the two force arms 22 to release the workpiece, and accurately completes operations such as clamping, flipping and transferring the workpiece, reducing the need for manual intervention, reducing errors caused by human factors, and greatly improving production efficiency.

[0031] In this embodiment, a plurality of guide sleeves 210 are installed at intervals on the movable support 21 , and the guide sleeves 210 are matched and connected with the guide rods 14 one by one to achieve a sliding connection between the movable support 21 and the guide rods 14 .

[0032] In this embodiment, V-shaped cutouts 230 are provided on the inner side of the clamping block 23. The design of the V-shaped cutouts 230 can increase the contact area between the clamping block 23 and the workpiece, which helps to disperse the clamping force, reduce the local pressure on the workpiece, and avoid damage to the workpiece during the clamping process. At the same time, the shape of the V-shaped cutouts 23 can match the contours of various workpieces, and can find the corresponding clamping position regardless of whether it is a straight line, a curve or a broken line, thereby improving the versatility and applicability of the clamping block.

[0033] In this embodiment, the extension and retraction direction of the clamping cylinder 26 is perpendicular to the axis direction of the rotating member 13 .

[0034] The above-mentioned automatic workpiece clamping and flipping device has a simple structure and is easy to use. A clamping jaw assembly 20 is installed on the rotating member 13, and is driven by the first bevel gear 120 and the second bevel gear 130. It can accurately complete operations such as clamping, flipping and transferring the workpiece, reducing the need for manual intervention, reducing errors caused by human factors, and greatly improving production efficiency.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
